PART I

Item 1.  Business

GENERAL
 
White Mountains Insurance Group, Ltd. (the “Company” or the “Registrant”) is an exempted Bermuda limited liability company whose principal businesses are conducted through its insurance and reinsurance subsidiaries. Within this report, the term “White Mountains” is used to refer to one or more entities within the consolidated organization, as the context requires. The Company’s headquarters is located at 14 Wesley Street, Hamilton, Bermuda HM 11, its principal executive office is located at 80 South Main Street, Hanover, New Hampshire 03755-2053 and its registered office is located at Clarendon House, 2 Church Street, Hamilton, Bermuda HM 11. White Mountains’ reportable segments are OneBeacon, Sirius Group, HG Global/BAM and Other Operations.
The OneBeacon segment consists of OneBeacon Insurance Group, Ltd. (“OneBeacon Ltd.”), an exempted Bermuda limited liability company that owns a family of U.S. based property and casualty insurance companies (collectively, “OneBeacon”). OneBeacon is a specialty property and casualty insurance writer that offers a wide range of insurance products through independent agencies, regional and national brokers, wholesalers and managing general agencies. As of December 31, 2012, White Mountains owned 75.2% of OneBeacon Ltd.’s outstanding common shares.  In October 2012, OneBeacon entered into a definitive agreement to sell its runoff business and in February 2012, OneBeacon sold its AutoOne Insurance business (“AutoOne”). Accordingly, the runoff business and AutoOne are presented as discontinued operations in White Mountains’ financial statements.
The Sirius Group segment consists of Sirius International Insurance Group, Ltd., an exempted Bermuda limited liability company, and its subsidiaries (collectively, “Sirius Group”). Sirius Group provides insurance and reinsurance products for property, accident and health, aviation and space, trade credit, marine, agriculture and certain other exposures on a worldwide basis through its subsidiaries, Sirius International Insurance Corporation (“Sirius International”), Sirius America Insurance Company (“Sirius America”) and Lloyd’s Syndicate 1945 (“Syndicate 1945”). Sirius Group also specializes in the acquisition and management of runoff insurance and reinsurance companies both in the United States and internationally through its White Mountains Solutions division. 
The HG Global/BAM segment consists of White Mountains’ investment in HG Global Ltd. (“HG Global”) and the consolidated results of Build America Mutual Assurance Company (“BAM”). During the third quarter of 2012, White Mountains capitalized HG Global with approximately $600 million to fund the start-up of BAM. BAM is a municipal bond insurer domiciled in New York that was established to provide insurance on bonds issued to support essential U.S. public purposes such as schools, utilities, core governmental functions and existing transportation facilities. HG Global, together with its subsidiaries, provided the initial capitalization of BAM through the purchase of $503 million of surplus notes issued by BAM (the “BAM Surplus Notes”). HG Global, through its wholly-owned subsidiary, HG Re Ltd. (“HG Re”), also provides 15%-of-par, first loss reinsurance protection for policies underwritten by BAM. As of December 31, 2012, White Mountains owned 97.3% of HG Global's preferred equity and 88.7% of its common equity. White Mountains does not have an ownership interest in BAM, which is a mutual insurance company owned by its members. However, accounting principles generally accepted in the United States (“GAAP”) requires White Mountains to consolidate BAM's results in its financial statements. BAM's results do not affect White Mountains' adjusted book value per share and are attributed to non-controlling interests.
White Mountains’ Other Operations segment consists of the Company and its intermediate holding companies, its wholly-owned investment management subsidiary, White Mountains Advisors LLC (“WM Advisors”), White Mountains’ variable annuity reinsurance business, White Mountains Life Reinsurance (Bermuda) Ltd. (“WM Life Re”), which is in runoff, as well as various other entities not included in other segments.
On October 7, 2011, White Mountains completed its sale of Esurance Holdings, Inc. and its subsidiaries (“Esurance Insurance”) and Answer Financial Inc. and its subsidiaries (“AFI”) (collectively, “Esurance”). Accordingly, Esurance is no longer a reportable segment and is included in discontinued operations in White Mountains’ financial statements.

White Mountains’ Operating Principles
 
White Mountains strives to operate within the spirit of four operating principles. These are:
 
Underwriting Comes First.  An insurance enterprise must respect the fundamentals of insurance. There must be a realistic expectation of underwriting profit on all business written, and demonstrated fulfillment of that expectation over time, with focused attention to the loss ratio and to all the professional insurance disciplines of pricing, underwriting and claims management.

Maintain a Disciplined Balance Sheet.  The first concern here is that insurance liabilities must always be fully recognized. Loss reserves and expense reserves must be solid before any other aspect of the business can be solid. Pricing, marketing and underwriting all depend on informed judgment of ultimate loss costs and that can be managed effectively only with a disciplined balance sheet.
 
Invest for Total Return. Historical insurance accounting has tended to hide unrealized gains and losses in the investment portfolio and over reward reported investment income (interest and dividends). Regardless of the accounting, White Mountains must invest for the best growth in value over time. In addition to investing our bond portfolios for total after-tax return, that will mean prudent investment in equities consistent with leverage and insurance risk considerations.

Think Like Owners.  Thinking like owners has a value all its own. There are stakeholders in a business enterprise and doing good work requires more than this quarter’s profit. But thinking like an owner embraces all that without losing the touchstone of a capitalist enterprise.

ONEBEACON

OneBeacon, with its U.S. corporate headquarters in Minnetonka, Minnesota, is a specialty property and casualty insurance writer that offers a wide range of insurance products through independent agencies, regional and national brokers, wholesalers and managing general agencies. As a specialty underwriter, OneBeacon believes that it will generate superior returns as compared to an underwriter that takes a more “generalist” underwriting approach and that its knowledge regarding its specialized insurance products, targeted industries, classes of business and risk characteristics provides it with a competitive edge when determining the terms and conditions on individual accounts. OneBeacon’s products relate to: professional liability, marine, energy, entertainment, sports and leisure, excess property, excess environmental, group accident, property and inland marine, public entities, technology, surety and tuition refund. Additionally, OneBeacon wrote collector cars and boats insurance through an exclusive underwriting agreement with Hagerty Insurance Agency (“Hagerty”) that was terminated effective January 1, 2013. See Collector Cars and Boats on page 5.
OneBeacon also has assets, liabilities and capital related to non-specialty business that it no longer writes, principally non-specialty commercial lines and certain other runoff business, including nearly all of its asbestos and environmental reserves (“Runoff Business”). On October 17, 2012, OneBeacon entered into a definitive agreement to sell the Runoff Business (the “Runoff Transaction”). Upon completion of the Runoff Transaction, which is expected to occur in the second half of 2013 subject to regulatory approval, OneBeacon will be focused exclusively on specialty business. See Discontinued Operations on page 24 for a description of the Runoff Transaction.
At December 31, 2012 and 2011, OneBeacon had $5.4 billion and $5.8 billion of total assets and $1.0 billion and $1.1 billion of common shareholders’ equity, respectively. At December 31, 2012 and 2011, White Mountains reported $251 million and $273 million of non-controlling interest related to its ownership in OneBeacon. OneBeacon wrote $1.2 billion and $1.1 billion in net written premiums in 2012 and 2011, respectively.

Following OneBeacon's announcement of the Runoff Transaction, A.M. Best, Fitch, Moody's and Standard & Poor's each issued a press release regarding the ratings implications. A.M. Best placed the Runoff Subsidiaries under review with negative implications; Fitch placed the Runoff Subsidiaries on credit watch negative; and Moody's assigned a negative outlook. Standard & Poor's downgraded and subsequently, at the request
of OneBeacon, withdrew its rating on the Runoff Subsidiaries. All four ratings agencies affirmed the ratings of the Ongoing Subsidiaries with
stable outlook.

Property and Casualty Insurance Overview
Generally, property and casualty insurance companies write insurance policies in exchange for premiums paid by their customers (the insured). An insurance policy is a contract between the insurance company and the insured where the insurance company agrees to pay for losses suffered by the insured that are covered under the contract. Such contracts often are subject to subsequent legal interpretation by courts, legislative action and arbitration.
OneBeacon writes both property insurance and casualty insurance. Property insurance generally covers the financial consequences of accidental losses to the insured’s property, such as a business’ building, inventory and equipment or personal property. Casualty insurance (often referred to as liability insurance) generally covers the financial consequences of a legal liability of an individual or an organization resulting from negligent acts and omissions causing bodily injury and/or property damage to a third party. Premiums from ocean and inland marine, private passenger auto, fire and allied lines and certain commercial multiple peril and auto policies generally represent OneBeacon’s property lines of business, and claims from such business are typically reported and settled in a relatively short period of time. Premiums from general liability, workers compensation, commercial and personal auto liability and certain commercial multiple peril policies generally represent OneBeacon’s casualty lines of business, and claims from such business can take years, even decades, to settle.

OneBeacon derives substantially all of its revenues from earned premiums, investment income and net realized and unrealized investment gains and losses on investment securities. Earned premiums represent premiums received from insureds, which are recognized as revenue over the period of time that insurance coverage is provided (i.e., ratably over the life of the policy). A significant period of time normally elapses between the receipt of insurance premiums and the payment of insurance claims. During this time, OneBeacon invests the premiums, earns investment income and generates net realized and unrealized gains and losses on investment activities.
Insurance companies incur a significant amount of their total expenses from policyholder losses, which are commonly referred to as claims. In settling policyholder losses, various loss adjustment expenses (“LAE”) are incurred such as insurance adjusters’ fees and litigation expenses. In addition, insurance companies incur policy acquisition expenses, such as commissions paid to agents and premium taxes, and other expenses related to the underwriting process, including their employees’ compensation and benefits. The key measure of relative underwriting performance for an insurance company is the combined ratio. An insurance company’s combined ratio under GAAP is calculated by adding the ratio of incurred loss and LAE to earned premiums (the “loss and LAE ratio”) and the ratio of policy acquisition and other underwriting expenses to earned premiums (the “expense ratio”). A combined ratio under 100% indicates that an insurance company is generating an underwriting profit. However, when considering investment income and investment gains or losses, insurance companies operating at a combined ratio of greater than 100% can be profitable.

A description of business written by each underwriting unit in OneBeacon’s Specialty Products follows:

OneBeacon Professional Insurance (“Professional Insurance”)

Additionally, Professional Insurance provides employment practices liability, management liability and other tailored products for complex organizations including health care provider excess insurance and HMO reinsurance. General liability, property and workers compensation coverages are also available for financial institutions. Professional Insurance policies are primarily issued on a “claims made” basis, which generally covers claims that are made against an insured during the time period when a liability policy is in effect, regardless of when the event causing the loss occurred. This coverage differs from “claims occurrence” basis policies, which generally cover losses on events that occur during a period specified in the policy, regardless of when the claim is reported.

Collector Cars and Boats
Through its exclusive partnership with Hagerty, OneBeacon offered tailored coverages for collectible vehicles and wooden boats, automotive museums and restoration shops. Notable features included agreed value for the insured vehicle or boat, flexible usage, and overseas shipping/foreign touring coverage supported by in-house claims expertise. In January 2013, OneBeacon and Hagerty terminated their relationship and OneBeacon sold Essentia Insurance Company (“Essentia”), an indirect wholly-owned subsidiary that wrote OneBeacon’s Hagerty collector car and boat business, to Markel Corporation. OneBeacon will recognize a $23 million pre-tax gain on sale ($15 million after tax) in the first quarter of 2013.

Tuition Reimbursement
A.W.G. Dewar, Inc. (“Dewar”) has been a leading provider of tuition reimbursement insurance since 1930. Dewar’s product, classified as credit insurance, protects both schools and parents from the financial consequences of a student's withdrawal or dismissal from school.

Marketing and Distribution
OneBeacon offers its products through a network of independent agents, regional and national brokers and wholesalers. Overall, OneBeacon has approximately 2,700 distribution relationships across the country. In recent years, OneBeacon has expanded its distribution channels to include select managing general agencies (“MGAs”), either through acquisitions or exclusive relationships. These MGAs focus on a particular customer group with tailored products and services, and related expertise.
OneBeacon protects the integrity of its franchise value by selectively appointing distribution partners that demonstrate business and industry knowledge and geographic profiles that align with its target markets and specialized capabilities. OneBeacon believes in the added value provided by independent distribution partners as they conduct more complete assessments of their clients’ needs, which result in more appropriate coverages and prudent risk management. OneBeacon also believes that independent insurance agencies and brokers will continue to be a significant force in overall industry premium production.

Underwriting and Pricing
OneBeacon believes there must be a realistic expectation of attaining an underwriting profit on all the business it writes, as well as a demonstrated fulfillment of that expectation over time. Consistent with the “underwriting comes first” operating principle, adequate pricing is a critical component for achieving an underwriting profit. OneBeacon underwrites its book with a disciplined approach towards pricing its insurance products and is willing to forgo a business opportunity if it believes it is not priced appropriately to the exposure.
OneBeacon actively monitors pricing activity and measures usage of tiers, credits, debits and limits. In addition, OneBeacon regularly updates base rates to achieve targeted returns on capital and attempts to shift writings away from lines and classes where pricing is inadequate. To the extent changes in premium rates, policy forms or other matters are subject to regulatory approval (see “REGULATION—United States” on page 26 and “Risk Factors—Regulation may restrict our ability to operate on page 38), OneBeacon proactively monitors its pending regulatory filings to facilitate, to the extent possible, their prompt processing and approval. Lastly, OneBeacon expends considerable effort to measure and verify exposures and insured values.

Competition
Property and casualty insurance is highly competitive. OneBeacon’s businesses each compete against a different subset of companies. In general terms, OneBeacon competes in one or more of its businesses with most of the large multi-line insurance companies, such as ACE, AIG, Chubb Group, CNA, Liberty Mutual, Travelers and Zurich Insurance Group. OneBeacon also competes with most of the specialty companies, such as Allied World Assurance Company, HCC Insurance Holdings, Inc., Ironshore Inc., Markel Corporation, RLI Corp. and W.R. Berkley Corporation. Lastly, OneBeacon competes in certain of its businesses with various local and regional insurance companies.
The more significant competitive factors for most insurance products OneBeacon offers are price, product terms and conditions, agency and broker relationships and claims service. OneBeacon’s underwriting principles and dedication to independent distribution partners are unlikely to make it the low-cost provider in most markets. While it is often difficult for insurance companies to differentiate their products, OneBeacon believes that by providing superior specialty products to satisfy market needs and relying on agents and brokers who value its targeted expertise, superior claims service, and disciplined underwriting, it establishes a competitive advantage. The continued existence of carriers operating with lower cost structures places ongoing pressure on OneBeacon’s pricing and terms and conditions, which may impact its ability to compete.

Claims Management
Effective claims management is a critical factor in achieving satisfactory underwriting results. OneBeacon maintains an experienced staff of appraisers, medical specialists, managers and field adjusters strategically located throughout its operating territories. OneBeacon also maintains a special investigative unit designed to detect insurance fraud and abuse and support efforts by regulatory bodies and trade associations to curtail fraud.
Claims operations are organized into ongoing claims and runoff claims, with specific claims resources supporting the respective operations. This approach allows OneBeacon to better identify and manage claims handling costs. In addition, a shared claims service unit manages costs related to all claims staff and vendors. OneBeacon has adopted a total claims cost management approach that gives equal importance to controlling claims handling expenses, legal expenses and claims payments, enabling it to lower the sum of the three. This approach requires the utilization of a considerable number of conventional metrics to monitor the effectiveness of various programs implemented to lower total loss costs. OneBeacon utilizes the metrics to guard against implementation of expense containment programs that will cost more than it expects to save.

OneBeacon’s claims department utilizes a claims workstation to record reserves, payments and adjuster activity and, with support from expert tools, assists each claim handler in identifying recovery potential, estimating property damage, evaluating claims and identifying fraud. OneBeacon’s commitment and performance in fighting insurance fraud has reduced claim costs and aided law enforcement investigations.

Catastrophe Risk Management and Reinsurance Protection
In the normal course of its business, OneBeacon purchases reinsurance from high-quality, highly rated, third-party reinsurers in order to minimize loss from large losses or catastrophic events.
The timing and size of catastrophe losses are unpredictable and the level of losses experienced in any year could be material to OneBeacon’s operating results and financial position. Examples of catastrophes include losses caused by earthquakes, wildfires, hurricanes and other types of storms and terrorist acts. The extent of losses caused by catastrophes is a function of the amount and type of insured exposure in the area affected by the event as well as the severity of the event. OneBeacon uses models (primarily AIR Worldwide (“AIR”) Version 12) to estimate the probability of the occurrence of a catastrophic event as well as potential losses under various scenarios. OneBeacon uses this model output in conjunction with other data to manage its exposure to catastrophe losses through individual risk selection and by limiting its concentration of insurance written in catastrophe-prone areas such as coastal regions. In addition, OneBeacon imposes wind deductibles on existing coastal windstorm exposures.
OneBeacon seeks to further reduce its potential loss from catastrophe exposures through the purchase of catastrophe reinsurance. Effective May 1, 2012, OneBeacon renewed its property catastrophe reinsurance program through April 30, 2013. The program provides coverage for OneBeacon’s property business as well as certain acts of terrorism. Under the program, the first $25 million of losses resulting from any single catastrophe are retained and the next $155 million of losses resulting from the catastrophe are reinsured in three layers, although OneBeacon retains a co-participation of 55% of losses from $25 million to $40 million, 15% of losses from $40 million to $80 million and 10% of losses from $80 million to $180 million. Thus, for a $180 million loss, OneBeacon would retain $49 million. Any loss above $180 million would be retained in full. In the event of a catastrophe, OneBeacon’s property catastrophe reinsurance program is reinstated for the remainder of the original contract term by paying a reinstatement premium that is based on the percentage of coverage reinstated and the original property catastrophe coverage premium. OneBeacon anticipates that the $180 million limit is sufficient to cover its Northeast windstorm losses with a modeled 0.4% probability of occurrence (1-in-250-year event). This $180 million limit was reduced from the $225 million limit that OneBeacon’s previous catastrophe reinsurance program provided, as a result of lower catastrophe exposure as a specialty-focused company.
In addition to the corporate catastrophe reinsurance protection that it secures, OneBeacon may also purchase dedicated
reinsurance protection for specific businesses. In 2012, OneBeacon purchased insurance to protect its collector cars and boats business from catastrophic losses. This treaty covered losses in excess of $2.5 million up to $25 million in two layers. The first layer, $2.5 million in excess of $2.5 million, carried a 5% co-participation. The company had a 20% co-participation on the second layer, $20 million in excess of $5 million. Catastrophe losses above $25 million are retained in full. Reinstatement premiums are paid if the coverage is attached.
OneBeacon also purchased a per-occurrence treaty for IMU that protects against large occurrences, whether a single large claim or a catastrophe. The IMU treaty attaches at $2 million per occurrence. Coverage is provided up to $60 million. The first layer of the marine treaty is $5 million in excess of $2 million, with an annual aggregate deductible of $1.5 million for large losses and $5 million for catastrophes losses. For losses in the second layer, $10 million excess of $50 million, OneBeacon retains half of the loss. Losses above $60 million are retained in full. Reinstatement premiums are paid in full or in part depending on the layer and the occurrence if the coverage is attached. The corporate catastrophe treaty provides coverage for losses retained under both the collector cars and boats and marine reinsurance treaties.
OneBeacon also purchases property-per-risk reinsurance coverage to reduce large loss volatility. The property-per-risk reinsurance program reinsures losses in excess of $10 million up to $100 million. Individual risk facultative reinsurance may be purchased above $100 million where OneBeacon deems it appropriate. Under the property-per-risk program, OneBeacon retains a co-participation of 10% for losses in excess of $20 million up to $50 million and a co-participation of 20% for losses in excess of $50 million. The property-per-risk program also provides one limit of reinsurance protection for losses in excess of $10 million up to $100 million on an individual risk basis for foreign terrorism losses. However, any nuclear events, or biological, chemical or radiological terrorist attacks are not covered.
OneBeacon also maintains a casualty reinsurance program that provides protection for individual policies involving general liability, automobile liability, professional liability or umbrella liability. OneBeacon’s healthcare professional liability treaty covers losses in excess of $5 million up to $20 million in two layers. The first layer, $5 million in excess of $5 million, has a 20% co-participation. All other casualty business is covered in a separate treaty covering losses in excess of $5 million up to $21 million. This treaty has a 22.5% co-participation in the first layer ($6 million in excess of $5 million) and a 10% co-participation in the second layer ($10 million in excess of $11 million). OneBeacon purchases a treaty to protect against large workers compensation losses that covers 100% of the loss in excess of $1 million up to $10 million per person. In addition, for casualty losses involving more than one insured, OneBeacon maintains a treaty that covers up to $40 million in excess of a $10 million retention.

OneBeacon’s property catastrophe reinsurance program does not cover property losses resulting from any nuclear events or biological, chemical or radiological terrorist attacks or losses resulting from acts of terrorism as defined under the Terrorism Risk Insurance Act of 2002 (the “Terrorism Act” or “TRIA”), as amended, committed by an individual or individuals acting on behalf of any foreign person or foreign interest, as well as domestic acts of terrorism. See “Terrorism” below.
Reinsurance contracts do not relieve OneBeacon of its obligation to its policyholders. Therefore, collectibility of balances due from reinsurers is critical to OneBeacon’s financial strength. See Note 4—“Third-Party Reinsurance” of the accompanying consolidated financial statements.

Terrorism
Since the terrorist attacks of September 11, 2001, OneBeacon has sought to mitigate the risk associated with any future terrorist attacks by limiting the aggregate insured value of policies in geographic areas with exposure to losses from terrorist attacks. This is accomplished by either limiting the total insured values exposed, or, where applicable, through the use of terrorism exclusions.
In December 2007, the U.S. government extended the Terrorism Act until December 31, 2014. The Terrorism Act established a federal “backstop” for commercial property and casualty losses, including workers compensation, resulting from acts of terrorism by or on behalf of any foreign person or foreign interest. As extended, the law now also covers domestic acts of terrorism. The law limits the industry’s aggregate liability by requiring the federal government to share 85% of certified losses once a company meets a specific retention or deductible as determined by its prior year’s direct written premiums and limits the aggregate liability to be paid by the government and industry without further action by Congress at $100 billion. In exchange for this “backstop,” primary insurers are required to make coverage available to commercial insureds for losses from acts of terrorism as specified in the Terrorism Act. The following types of coverage are excluded from the Terrorism Act: commercial automobile, burglary and theft, surety, farmowners multi-peril and all professional liability coverage except directors and officers coverage.
OneBeacon estimates its individual retention level for commercial policies subject to the Terrorism Act to be approximately $100 million in 2013. The federal government will pay 85% of covered terrorism losses that exceed OneBeacon’s or the industry’s retention levels in 2013, up to a total of $100 billion.
OneBeacon’s current property and casualty catastrophe reinsurance programs provide coverage for both “certified” and “non-certified” events as defined under the Terrorism Act provided such losses are not the result of a nuclear, biological, chemical or radiological terrorist attack, or for “certified” acts committed by an individual or individuals acting on behalf of any foreign person or foreign interest. See “Catastrophe Management and Reinsurance Protection” above.
OneBeacon closely monitors and manages its concentration of risk by geographic area. OneBeacon’s guideline is to control its exposures so that its total maximum expected loss from a likely terrorism event within any half-mile radius in a metropolitan area or around a target risk will not exceed $200 million, or $300 million in all other areas, before considering the Terrorism Act. Reports monitoring OneBeacon’s terrorism exposures are generated quarterly, and the exposure of potential new business located in areas of existing concentration or that individually present significant exposure is evaluated during the underwriting process. As a result, OneBeacon believes that it has taken appropriate actions to limit its exposure to losses from terrorist attacks and will continue to monitor its terrorism exposure in the future. Nonetheless, risks insured by OneBeacon, including those covered by the Terrorism Act, remain exposed to terrorist attacks and the possibility remains that losses resulting from future terrorist attacks could prove to be material.

Loss and Loss Adjustment Expense Reserves
OneBeacon establishes loss and LAE reserves that are estimates of future amounts needed to pay claims and related expenses for insured events that have already occurred. The process of estimating reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain. See “CRITICAL ACCOUNTING ESTIMATES — Loss and LAE Reserves — OneBeacon” on page 75 for a full discussion regarding OneBeacon’s loss reserving process.
The following information presents (1) OneBeacon’s reserve development over the preceding ten years and (2) a reconciliation of reserves on a regulatory basis to reserves determined in accordance with GAAP, each as prescribed by Securities Act Industry Guide No. 6.
Section I of the 10 year table shows the estimated liability that was recorded at the end of each of the indicated years for all current and prior accident year unpaid loss and LAE. The liability represents the estimated amount of loss and LAE for claims that were unpaid at the balance sheet date, including incurred but not reported (“IBNR”) reserves. In accordance with GAAP, the liability for unpaid loss and LAE is recorded in the balance sheet gross of the effects of reinsurance with an estimate of reinsurance recoverables arising from reinsurance contracts reported separately as an asset. The net balance represents the estimated amount of unpaid loss and LAE outstanding as of the balance sheet date, reduced by estimates of amounts recoverable under reinsurance contracts.

10


Section II shows the cumulative amount of net loss and LAE paid relating to recorded liabilities as of the end of each succeeding year. Section III shows the re-estimated amount of the previously recorded net liability as of the end of each succeeding year. Estimates of the liability for unpaid loss and LAE are increased or decreased as payments are made and more information regarding individual claims and trends, such as overall frequency (the average number of claims submitted per policy during a given period of time) and severity (the average value of claims submitted per policy during a given period of time) patterns, becomes known. Section IV shows the cumulative net (deficiency)/redundancy representing the aggregate change in the liability from original balance sheet dates and the re-estimated liability through December 31, 2012. Section V shows the re-estimated gross liability and re-estimated reinsurance recoverables through December 31, 2012. Section VI shows the cumulative gross (deficiency)/redundancy representing the aggregate change in the liability from original balance sheet dates and the re-estimated liability through December 31, 2012.

OneBeacon’s Senior Notes

2012 OBH Senior Notes
In November 2012, OneBeacon U.S. Holdings, Inc. (“OBH”), an intermediate holding company of OneBeacon, issued $275 million face value of senior unsecured debt (the “2012 OBH Senior Notes”) through a public offering, at an issue price of 99.9%. The net proceeds from the issuance of the 2012 OBH Senior Notes were used to repurchase OBH's existing outstanding senior notes, the 2003 OBH Senior Notes (as defined below). The OBH 2012 Senior Notes, which are fully and unconditionally guaranteed as to the payment of principal and interest by OneBeacon Ltd., bear an annual interest rate of 4.6%, payable semi-annually in arrears on May 9 and November 9 until maturity on November 9, 2022. See Note 6 - Debt for more details regarding the 2012 OBH Senior Notes.

2003 OBH Senior Notes
In May 2003, OBH issued $700 million face value of senior unsecured debt (the “2003 OBH Senior Notes”) through a public offering, at an issue price of 99.7%. The 2003 OBH Senior Notes had an annual interest rate of 5.875%, payable semi-annually in arrears on May 15 and November 15, and were scheduled to mature on May 15, 2013.
From 2008 through 2011, OneBeacon repurchased a total of $430 million of the face value of its outstanding 2003 OBH Senior Notes through various transactions. In the fourth quarter of 2012, in connection with the issuance of the 2012 OBH Senior Notes, OBH purchased and retired the remaining $270 million aggregate principal amount of outstanding 2003 OBH Senior Notes for $276 million.

Reinsurance Overview
Reinsurance is an arrangement in which a reinsurance company (the ‘‘reinsurer’’) agrees to indemnify an insurance company (the ‘‘ceding company’’) for insurance risks underwritten by the ceding company. Reinsurance can benefit a ceding company in a number of ways, including reducing exposure on individual risks, providing catastrophe protections from large or multiple losses, and assisting in maintaining acceptable capital levels as well as financial and operating leverage ratios. Reinsurance can also provide a ceding company with additional underwriting capacity by permitting it to accept larger risks and underwrite a greater number of risks without a corresponding increase in its capital. Reinsurers may also purchase reinsurance, known as retrocessional reinsurance, to cover risks assumed from ceding companies. Reinsurance companies often enter into retrocessional agreements for many of the same reasons that ceding companies enter into reinsurance agreements.
Reinsurance is generally written on a treaty or facultative basis. Treaty reinsurance is an agreement whereby the reinsurer assumes a specified portion or category of risk under all qualifying policies issued by the ceding company during the term of the agreement, usually one year. When underwriting treaty reinsurance, the reinsurer does not evaluate each individual risk and generally accepts the original underwriting decisions made by the ceding company. Treaty reinsurance is typically written on either a proportional or excess of loss basis. A proportional reinsurance treaty is an arrangement whereby a reinsurer assumes a predetermined proportional share of the premiums and losses generated on specified business. An excess of loss treaty is an arrangement whereby a reinsurer assumes losses that exceed a specific retention of loss by the ceding company. Facultative reinsurance, on the other hand, is underwritten on a risk-by-risk basis, which allows the reinsurer to determine pricing for each exposure.
Sirius Group writes treaty and facultative reinsurance, as well as primary direct business. The majority of Sirius Group's premiums are derived from excess of loss and proportional reinsurance contracts, which in 2012 amounted to 63% and 19%, respectively, of its total net written premiums, while primary direct business represented 18% of total net written premiums.
A significant period of time normally elapses between the receipt of reinsurance premiums and the payment of reinsurance claims. While premiums are generally paid to the reinsurer upon inception of the underlying coverage, the claims process is delayed and generally begins upon the occurrence of an event causing an insured loss followed by: (1) the reporting of the loss by the insured to its broker or agent; (2) the reporting by the broker or agent to the ceding company; (3) the reporting by the ceding company to its reinsurance intermediary or agent; (4) the reporting by the reinsurance intermediary or agent to the reinsurer; (5) the ceding company’s adjustment and payment of the loss; and (6) the payment to the ceding company by the reinsurer. During this time, reinsurers invest the premiums and earn investment income and generate net realized and unrealized investment gains and losses on investments. The period of time between the receipt of premiums and the payment of claims is typically longer for a reinsurer than for a primary insurer.

For each of the years ended December 31, 2012, 2011 and 2010, 82%, 85%, and 86%, respectively, of Sirius Group’s net written premiums were for reinsurance products, with the remainder being insurance products. Sirius Group is expanding its primary direct business in the United States for the accident and health line, which could result in increased direct insurance business for years 2013 and forward.

Accident and Health
Sirius Group is an insurer of direct accident and health insurance business in the U.S., either on an admitted or surplus lines basis, as well as international medical business written through International Medical Group, Inc. (“IMG”), which is the largest agent writing on Sirius Group's behalf. In 2012, Sirius Group had $114 million in gross written premiums through IMG. Sirius Group also writes proportional and excess treaties covering employer medical stop loss for per person (specific) and per employer (aggregate) exposures. In addition, Sirius Group writes some medical, health and personal accident coverages written on a treaty and facultative basis.

Other Property
Sirius Group is a leader in the broker market for property treaties written on a proportional and excess of loss basis.  For its international business, the book consists of treaty, written on both a proportional and excess of loss basis, facultative, and direct business, primarily in Europe. In the United States, the book predominantly centers on significant participations on proportional and excess of loss treaties for carefully chosen partners in the excess & surplus lines segment of the market.

Property Catastrophe Excess
Property catastrophe excess of loss treaties cover losses from catastrophic events. Sirius Group writes a worldwide portfolio with the largest concentration of exposure in Europe and the United States, and seeks to set prices and terms on treaties wherever possible. The U.S. book written in Bermuda has a national account focus supporting principally the lower and/or middle layers of large capacity programs. Additionally, Stockholm writes a U.S. portfolio mainly consisting of select small regional and standard lines carriers. The exposures written in the international portfolio are diversified across many countries, regions and perils.

Trade Credit
Sirius Group writes credit and bond reinsurance, mostly on companies with worldwide operations. Most debtors are based in Europe, representing approximately 62% of Sirius Group’s exposure. The bulk of the business is traditional short term commercial credit insurance, covering pre-agreed domestic and export sales of goods and services with typical coverage periods of 60 to 120 days. Losses under these policies (protection of undisputed debts against declared insolvency and protracted default) are correlated to adverse changes in a respective country’s gross national product.

Aviation and Space
Aviation insurance covers loss of or damage to an aircraft and the aircraft operations’ liability to passengers, cargo and hull as well as to third parties. Additionally, liability arising out of non-aircraft operations such as hangars, airports and aircraft products can be covered. Space insurance covers loss of or damage to a satellite during launch and in orbit.  The book consists of treaty, written on both on a proportional and excess of loss basis, facultative, and direct business.


14


Marine
Sirius Group provides marine reinsurance, primarily written on an excess of loss and proportional basis.  Coverage offered includes damage to ships and goods in transit, marine liability lines, and offshore energy industry insurance. Sirius Group also writes yacht business, both on a reinsurance and a direct basis. The marine portfolio is diversified across many countries and regions.

Agriculture
Sirius Group primarily provides proportional and stop loss coverage to companies writing U.S. government-sponsored Multi-Peril Crop Insurance (“MPCI”). Sirius Group’s participation is net of the government’s stop loss reinsurance protection. Sirius Group also provides coverage for crop-hail and certain named perils when bundled with MPCI business.  Sirius Group also writes some agriculture business outside of the United States.

Contingency
Sirius Group underwrites contingency insurance, primarily for event cancellation and non-appearance, primarily on a direct policy and facultative reinsurance basis.  Additionally, coverage for liabilities arising from contractual bonus, prize redemption and over-redemption is also offered.  The contingency portfolio is diversified across many countries and regions.

Casualty
Through 2011, Sirius Group’s casualty treaty division accepted reinsurance submissions for all lines of general casualty and professional liability business.  Due to insufficient U.S. casualty premium rates and global interest rates, the overall casualty book of business has decreased over time and effective January 1, 2012, Sirius Group no longer writes casualty business other than incidental exposures. Sirius Group could resume writing casualty business if premium rates and contract terms improve to favorable levels.

Lloyd’s Syndicate
In 2011, Sirius Group established Syndicate 1945, and focused on writing accident and health and contingency business.  Effective in 2013, Syndicate 1945 licenses have been approved to include property and marine business. Syndicate 1945 began writing business effective July 1, 2011 and had gross written premiums net of commissions of $58 million and $5 million in 2012 and 2011, respectively.  Syndicate 1945 has Lloyd's approved net capacity for 2013 of £93 million ($150 million based on the December 31, 2012 GBP to USD exchange rate).

White Mountains Solutions
White Mountains Solutions is a Connecticut-based division of Sirius Group specializing in the acquisition and management of runoff liabilities for insurance and reinsurance companies both in the United States and internationally.  The White Mountains Solutions team is comprised of a dedicated group of financial, actuarial and claims professionals experienced in the management and resolution of complex insurance liabilities as well as the structuring of transactions designed to enable owners to exit an insurance business and extract trapped capital. Acquisitions typically involve purchases at a significant discount to book value and undergo an extensive due diligence process. Sirius Group can derive value from these acquisitions not only from the discount purchase price, but also from the investment income on insurance float, the potential settlement of claims below the carried level of reserves and the harvesting of other embedded assets, including the value of shell companies and licenses.
 Since its formation in 2004, White Mountains Solutions has executed eleven transactions, which have resulted in approximately $163 million of cumulative after-tax income through December 31, 2012.
In November 2012, White Mountains Solutions completed the acquisitions of four runoff entities following receipt of regulatory approvals. The transactions entail the acquisition of Physicians Insurance Company of Ohio (“PICO”) and Citation Insurance Company (“Citation”) from PICO Holdings and also the acquisition of two American International Group, Inc. (“AIG”) runoff subsidiaries, American General Indemnity Company (“American General”) and American General Property Insurance Company (“American General Property”). White Mountains Solutions acquired 100% of the stock of PICO and Citation for a purchase price of $15 million and 100% of the stock of American General and American General Property for a purchase price of $35 million. In total, the transactions resulted in an after-tax gain of $14 million recorded in other revenues.
In addition, on December 11, 2012, White Mountains Solutions announced the execution of a definitive agreement to acquire American Fuji Fire and Marine Insurance Company from AIG, and on February 15, 2013 executed a definitive agreement to acquire Empire Insurance Company from Leucadia National Corporation. Both of these transactions are expected to close during the first half of 2013 subject to receipt of regulatory approvals.
On December 30, 2011, Sirius Group completed a transaction led by White Mountains Solutions to acquire the runoff loss reserve portfolio of Old Lyme Insurance Company Ltd. (“Old Lyme”), a Bermuda reinsurer in runoff since 2008. Old Lyme's loss reserves of approximately $23 million were transferred via novation agreements into White Shoals Re Ltd. (“White Shoals”), a wholly-owned Bermuda reinsurance company established by Sirius Group earlier in 2011. The transaction resulted in an after-tax gain of $7 million recorded in other revenues.

15


 On February 26, 2010, White Mountains Solutions completed the acquisition of Central National from Drum Financial Corporation for $5 million. Central National ceased writing business in 1989 and has operated under the control of the Nebraska Department of Insurance since 1990. The transaction resulted in an after-tax gain of $13 million recorded in other revenues.

Marketing and Distribution
Sirius Group obtains most of its reinsurance submissions from reinsurance intermediaries that represent the ceding company. The process of placing an intermediary reinsurance program typically begins when a ceding company enlists the aid of a reinsurance intermediary in structuring a reinsurance program. The ceding company and the reinsurance intermediary will often consult with one or more lead reinsurers as to the pricing and contract terms for the reinsurance protection being sought. Once the ceding company has approved the terms quoted by the lead reinsurer, the reinsurance intermediary will offer participation to qualified reinsurers until the program is fully subscribed. Sirius Group considers both the reinsurance intermediary and the ceding company to be its clients in any placement. Sirius Group has developed strong business relationships over a long period of time with the management of many of its ceding companies and reinsurance intermediaries.
Sirius Group pays ceding companies a ceding commission under most proportional reinsurance treaties and some excess of loss reinsurance treaties. The ceding commission is generally based on the ceding company’s cost of acquiring and administering the business being reinsured (e.g., agent commissions, premium taxes and certain miscellaneous expenses). The ceding commissions paid to ceding companies constitute the majority of Sirius Group’s total acquisition costs. Additionally, Sirius Group pays reinsurance intermediaries commissions based on negotiated percentages of the premium they produce.
During the years ended December 31, 2012, 2011 and 2010, Sirius Group received no more than 10% of its gross written premiums from any individual ceding company. During the years ended December 31, 2012, 2011, and 2010, Sirius Group received a majority of its gross reinsurance premiums written from three major, third-party reinsurance intermediaries as detailed in the following table:

Underwriting and Pricing
Sirius Group maintains a disciplined underwriting strategy which, while considering overall exposure, focuses on writing more business when market terms and conditions are favorable and reducing business volume during soft markets when terms and conditions become less favorable. Sirius Group offers clients a wide range of reinsurance products across multiple lines of business to satisfy their risk management needs.
Sirius Group derives its reinsurance business from a broad spectrum of ceding companies, including national, regional, specialty, and excess and surplus lines writers, both internationally and in the United States. Sirius Group prices its products by assessing the desired return on the expected capital needed to write a given contract and on the expected underwriting results of the contract. Sirius Group’s pricing indications are based on a number of underwriting factors including historical results, analysis of exposure and estimates of future loss costs, a review of other programs displaying similar exposure characteristics and the ceding company’s underwriting and claims experience. Additionally, in the United States, Sirius Group’s underwriters, actuaries and claims personnel perform audits of certain ceding companies. Generally, ceding company audits are not customary outside the United States. Sirius Group’s staff reviews the financial stability and creditworthiness of all ceding companies globally. Such reviews provide important input to support underwriting decisions.

Reinsurers do not have the stringent regulations with respect to contract terms and policy exclusions that are generally imposed on primary insurers. For example, the Terrorism Act is not applicable to reinsurers. As a result, terrorism exclusions on reinsurance contracts are dictated by the marketplace. Sirius Group evaluates terrorism exposure from its ceding companies and applies exclusions as it deems appropriate and as are permitted by market conditions. Reinsurance on U.S. commercial risks written by Sirius Group subsequent to the terrorist acts of September 11, 2001 generally contains clauses that exclude acts of terrorism certified under the Terrorism Act. Reinsurance on personal risks written by Sirius Group subsequent to the terrorist acts of September 11, 2001 generally contains exclusions related to nuclear, biological, radiological and chemical attacks.

Competition
The worldwide insurance and reinsurance markets are highly competitive. Competition is influenced by a variety of factors, including price charged and other terms and conditions offered, financial strength ratings, prior history and relationships, as well as expertise and the speed at which the company has historically paid claims.
Sirius Group competes for business in Europe, Bermuda, the United States, and other international markets with numerous global competitors. Sirius Group's competitors include other insurance and reinsurance companies and underwriting syndicates at Lloyd's of London. Some of the companies that Sirius Group competes directly with include Allied World Assurance Company Holdings AG, Arch Capital Group Ltd., Aspen Insurance Holdings Ltd., Axis Capital Holdings, Ltd., Endurance Specialty Holdings Ltd., Everest Re Group, Ltd., General Reinsurance Corporation, Hannover Ruckversicherung AG, Montpelier Re Holdings, Ltd., Munich Re Group, Odyssey Re Holdings Corp., PartnerRe Ltd., Platinum Underwriters Holdings Ltd., Renaissance Re Holdings Ltd., Scor Global P&C, Swiss Re Group, Transatlantic Holdings, Inc., Validus Holdings, Ltd., and XL Capital Ltd.
In addition, in recent years the persistent low interest rate environment and ease of entry into the reinsurance sector has led to increased competition in the property catastrophe excess reinsurance line. This alternative capital provides collateralized property catastrophe protection in the form of catastrophe bonds, industry loss warranties, sidecars and other vehicles that facilitate the ability for non-reinsurance entities, such as hedge funds and pension funds, to compete for property catastrophe excess reinsurance business outside of the traditional treaty market. Sirius Group has observed reduced pricing and/or reduced shares in certain property catastrophe excess reinsurance markets as a result.

Claims Management
Sirius Group maintains a staff of experienced insurance and reinsurance claim specialists.  Its reinsurance claims specialists work closely with intermediaries to obtain specific claims information from ceding companies. Where customary and appropriate, Sirius Group’s claims staff performs selective on-site claim reviews to assess ceding companies’ claim handling abilities and reserve techniques. In addition, Sirius Group’s claims specialists review loss information provided by ceding companies for adequacy and accuracy. The results of these claim reviews are shared with the underwriters and actuaries to assist them in pricing products and establishing loss reserves.
Sirius Group also uses TPAs for certain claims, including claims arising from certain of Sirius Group’s runoff claims related to certain acquired companies. Sirius Group’s claims staff performs on-site claim audits of certain TPAs to ensure the propriety of the controls and processes over claims serviced by the TPAs.

Catastrophe Risk Management
Sirius Group has exposure to losses caused by hurricanes, earthquakes, tornadoes, winter storms, windstorms, floods, tsunamis, terrorist acts and other catastrophic events. In the normal course of business, Sirius Group regularly manages its concentration of exposures to catastrophic events, primarily by limiting concentrations of exposure to what it deems acceptable levels and, if necessary, purchasing reinsurance. In addition, Sirius Group seeks to limit losses that might arise from acts of terrorism in its insurance and reinsurance contracts by exclusionary provisions where available.
Sirius Group licenses third-party global property catastrophe models from AIR Worldwide Corporation (“AIR”) and Risk Management Solutions Inc. (“RMS”), which are two of the leading vendors of industry-standard catastrophe modeling software, as well as utilizing its own proprietary models to calculate expected probable maximum loss (“PML”) from various property natural catastrophe scenarios. Sirius Group prices its property catastrophe contracts using the aforementioned third-party software and internal models and other methods. In 2012, Sirius Group started using a new proprietary property underwriting and pricing tool (“GPI”), which consolidates and reports on all its worldwide property exposures.  GPI is used to calculate individual and aggregate PMLs by statistically blending multiple third-party and proprietary models. For business that Sirius Group determines to have exposure to natural catastrophic perils, as part of its underwriting process it models and assesses the exposure to assess whether there is an appropriate premium for the exposure.

(1) Adjusted GAAP capital and common shareholder’s equity at December 31, 2012 for Sirius Group is determined on a legal-entity basis and
excludes $58 of equity in net unrealized gains from Symetra’s fixed maturity portfolio, net of taxes.

In addition to the above, Sirius Group also has significant exposure to United States Gulf Coast windstorms (i.e., Florida to Texas), New Madrid earthquakes, and, to a lesser extent, Japanese, Latin American and Canadian windstorms and earthquakes. 
AIR and RMS provide new versions of their models on a periodic basis, usually annually or every other year, which Sirius Group will implement for use upon appropriate testing and achieving comfort with the model enhancements. In 2011, RMS released Version 11, which significantly increased expected losses to the wind models in the United States and Europe.  For example, expected U.S. and European RMS insured industry annual aggregate wind loss increased 35% and 65%, respectively, versus the prior RMS version. Two of the main drivers of the U.S. wind increases were slower inland decay of winds from the coast, which would cause larger losses farther inland, and updates to structure and contents vulnerability, especially for commercial lines. Key drivers of the European model change included a full spectrum of smaller storm events that significantly increased short-term losses and annual aggregate losses, and an improved clustering model. Clustering is defined as the heightened risk that many losses might occur in a single year based on atmospheric conditions.
Prior to January 2012, Sirius Group used AIR Version 12 to estimate its PMLs in the United States. With GPI, Sirius Group enhanced its PML reporting methodology for exposures in the United States to approximate an averaging of AIR and RMS, further adjusted for each treaty by underwriting judgment regarding the specific exposures underlying each cedent's portfolio.  For exposures in countries other than the United States, Sirius Group chooses either AIR or RMS for PML reporting based on underwriting and actuarial assessment as to the integrity of the model by territory and underlying data availability.  The model of choice is then further adjusted in GPI for each treaty by underwriting judgment regarding the specific exposures underlying each cedent's portfolio.
Catastrophe modeling is dependent upon several broad economic and scientific assumptions, such as storm surge (the water that is pushed toward the shore by the force of a windstorm), demand surge (the localized increase in prices of goods and services that often follows a catastrophe) and zone density (the percentage of insured perils that would be affected in a region by a catastrophe). Third-party modeling software also does not provide information for all territories or perils (e.g. tsunami) for which Sirius Group writes business.
Catastrophe modeling is inherently uncertain due to process risk (i.e. the probability and magnitude of the underlying event) and parameter risk (i.e. the probability of making inaccurate model assumptions). In particular, obtaining geographic and policy coverage data on the primary policies reinsured by Sirius Group is essential. Accordingly, Sirius Group’s ability to develop its catastrophe exposure is dependent on the quality and accuracy of data obtained from its clients.
If Sirius Group’s assumptions about any of the above variables are incorrect, the potential incurred losses from an actual catastrophe could be materially higher than the expectation of losses generated from modeled catastrophe scenarios; as a result, Sirius Group’s results of operations and financial condition could be materially adversely affected.
Sirius Group does not believe that it can rely solely upon catastrophe modeling to measure its exposure to natural catastrophe risk. For example, the losses arising from hurricane Katrina for both Sirius Group and the industry were substantially in excess of losses previously predicted by third-party models from such an event. This was due to issues such as inadequate storm surge and demand surge assumptions in the models, as well as flooding from levees breaking which was not fully contemplated in these models. Sirius Group monitors gross and net property catastrophe occurrence limits by country and region globally. Occurrence limits for peak zones in Europe, Japan, and the United States are assessed versus modeled catastrophe risk as another measure in understanding total property catastrophe exposure to large events.

Reinsurance Protection
Sirius Group's reinsurance protection primarily consists of pro-rata and excess of loss protections to cover aviation, trade credit, and certain property exposures. Sirius Group's proportional reinsurance programs provide protection for part of the non-proportional treaty accounts written in Europe, the Americas, Asia, the Middle East, and Australia.  These reinsurance protections are designed to increase underwriting capacity where appropriate, and to reduce exposure both to large catastrophe losses and to a frequency of smaller loss events.  Attachment points and coverage limits vary by region around the world. In addition to its proportional reinsurance, Sirius Group also purchases excess of loss reinsurance protection for $15 million in excess of a retention of $5 million for the facultative and direct property portfolios written by the Stockholm, Hamburg and London branches (excluding business written in the United States).  For the facultative and direct property portfolios written by the Hamburg and Stockholm branches, an additional $15 million of reinsurance protection in excess of the $20 million coverage has been purchased for 2013. Sirius Group also has $5 million of protection in excess of a retention of $5 million for the London branch for facultative and direct U.S.-catastrophe exposed business (excluding Florida risks), which was renewed through June 30, 2013. As a result of hurricane Sandy in October 2012, Sirius Group recognized a full $5 million recovery on this account.
In 2012, 2011 and 2010, Sirius Group has had in place group excess of loss retrocessional coverage for its non-U.S. and non-Japan earthquake-related exposures. This cover was renewed for one year at April 1, 2012, providing $17 million of reinsurance protection through partially placed coverage of a $40 million layer in excess of Sirius Group's retention of $35 million. In addition, Sirius Group purchased two industry loss warranty (“ILW”) contracts that provide $10 million of coverage for a first event non-U.S. and non-Japan earthquake loss at a market loss event of $7.5 billion or more, with $5 million of additional coverage for a second market loss event at this level. Sirius Group also has $38 million of New Madrid earthquake ILW coverage through March 2013 that provides reinsurance protection both on a first and second market event of $20 billion.
In addition, Sirius Group has an ILW providing $5 million of coverage for a first loss European windstorm and flood at a market loss event of $5 billion, which expires March 2013. During the fourth quarter 2012, additional ILW protections providing $40 million of reinsurance coverage were purchased at different market loss levels for wind, flood, and all natural perils in Europe or Scandinavia, with the majority of these covers expiring in March 2013.
As of December 31, 2012, losses incurred from the February 2011 New Zealand earthquake totaled $47 million, $2 million of which was covered by Sirius Group’s non U.S. and non-Japan earthquake coverage.  During 2010, as a result of the Chile Earthquake in February 2010 Sirius Group recovered $65 million under its non U.S. and non-Japan earthquake coverage, which was a full limit loss.
Sirius Group's aviation reinsurance program is intended to reduce exposure to a frequency of small losses, a single large loss, or a combination of both.  In 2013, for the proportional and facultative aviation portfolios, reinsurance protection purchases were generally for coverage on losses from events that cause a market loss in excess of $150 million up to a full airline policy limit of $2 billion, including clash coverage. This program is in effect through November 2013. For the non-proportional aviation portfolio, reinsurance protection includes a 15% quota share treaty. In addition, the non-proportional portfolio is protected by $33 million in the form of first event ILWs, and $5 million of available limit in the form of second event ILWs. The first event ILWs attach at industry loss levels between $400 million and $1 billion.
For the marine yacht portfolio written by the London branch, reinsurance coverage is in place for $10 million in excess of a retention of $250,000.
For accident and health, Sirius Group has excess of loss protection covering personal accident and life of €10 million ($13 million based on the December 31, 2012 EUR to USD exchange rate) of protection in excess of a €5 million ($7 million based on the December 31, 2012 EUR to USD exchange rate) retention for the Stockholm, Hamburg, Liege and Singapore branches.
For 2012, Sirius Group ceded 20% and 50% of its trade credit and bond business, respectively, under a quota share retrocession, which supported growth in this line.  The treaty was renewed for 2013.
Almost all of Sirius Group's excess of loss reinsurance protections, excluding ILWs, include provisions that reinstate coverage at a cost of 100% or more of the original reinsurance premium.
 At December 31, 2012, Sirius Group had $15 million of reinsurance recoverables on paid losses and $322 million of reinsurance recoverables on unpaid losses that will become recoverable if claims are paid in accordance with current reserve estimates. Because retrocessional reinsurance contracts do not relieve Sirius Group of its obligation to its insureds, the collectability of balances due from Sirius Group's reinsurers is critical to its financial strength. Sirius Group monitors the financial strength and ratings of retrocessionaires on an ongoing basis. See Note 4 - “Third-party Reinsurance” to the accompanying consolidated financial statements for a discussion of Sirius Group's top reinsurers.

Loss and Loss Adjustment Expense Reserves
Sirius Group establishes loss and LAE reserves that are estimates of future amounts needed to pay claims and related expenses for insured events that have already occurred. The process of estimating reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain. See “CRITICAL ACCOUNTING ESTIMATES — Loss and LAE Reserves — Sirius Group” on page 86 for a full discussion regarding Sirius Group’s loss reserving process.
The following information presents (1) Sirius Group’s reserve development over the preceding ten years and (2) a reconciliation of reserves on a regulatory basis to reserves determined in accordance with GAAP, each as prescribed by Securities Act Industry Guide No. 6.
Section I of the 10 year table shows the estimated liability that was recorded at the end of each of the indicated years for all current and prior accident year unpaid loss and LAE. The liability represents the estimated amount of loss and LAE for claims that were unpaid at the balance sheet date, including IBNR reserves. In accordance with GAAP, the liability for unpaid loss and LAE is recorded in the balance sheet gross of the effects of reinsurance with an estimate of reinsurance recoverables arising from reinsurance contracts reported separately as an asset. The net balance represents the estimated amount of unpaid loss and LAE outstanding as of the balance sheet date, reduced by estimates of amounts recoverable under reinsurance contracts.
Section II shows the cumulative amount of net loss and LAE paid relating to recorded liabilities as of the end of each succeeding year. Section III shows the re-estimated amount of the previously recorded net liability as of the end of each succeeding year. Estimates of the liability for unpaid loss and LAE are increased or decreased as payments are made and more information regarding individual claims and trends, such as overall frequency and severity patterns, becomes known. Section IV shows the cumulative net (deficiency)/redundancy representing the aggregate change in the liability from original balance sheet dates and the re-estimated liability through December 31, 2012. Section V shows the re-estimated gross liability and re-estimated reinsurance recoverables through December 31, 2012. Section VI shows the cumulative gross (deficiency)/redundancy representing the aggregate change in the liability from original balance sheet dates and the re-estimated liability through December 31, 2012.

The cumulative net (deficiency)/redundancy in the table above includes adverse development from A&E claims. Sirius Group’s exposure to A&E claims results mainly from asbestos claims arising from treaty and facultative contracts written prior to 1985 at two companies acquired by Sirius America—MONY Reinsurance Corporation in 1991 and Christiania General Insurance Corporation in 1996. As a result, the table above reflects reserve development on A&E business that was not underwritten by Sirius Group.

21


Sirius Group’s net incurred losses from A&E claims have totaled $253 million over the past ten years. Although losses arising from A&E claims were on contracts that were not underwritten by Sirius Group, Sirius Group is liable for any additional losses arising from such contracts. Accordingly, Sirius Group cannot guarantee that it will not incur additional A&E losses in the future. Refer to “CRITICAL ACCOUNTING ESTIMATES” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for further details of Sirius Group’s A&E reserves.

Sirius Group’s Preference Shares and Senior Notes
In May 2007, Sirius International Group, Ltd. (“SIG”), an intermediate holding company of Sirius Group, issued $250 million non-cumulative perpetual preference shares, with a $1,000 per share liquidation preference (the “SIG Preference Shares”), and received $246 million of proceeds, net of $4 million of issuance costs and commissions. These shares were issued in an offering that was exempt from the registration requirements of the Securities Act of 1933. Holders of the SIG Preference Shares receive dividends on a non-cumulative basis when and if declared by SIG. See Note 1 - Significant Accounting Policies - Non-controlling Interest for more details regarding the SIG Preference Shares.
In March 2007, SIG issued $400 million face value of senior unsecured notes (the “SIG Senior Notes”) at an issue price of 99.715%. The SIG Senior Notes, which were issued in an offering that was exempt from the registration requirements of the Securities Act of 1933, bear an annual interest rate of 6.375%, payable semi-annually in arrears on March 20 and September 20, until maturity in March 2017. See Note 6 - Debt for more details regarding the SIG Senior Notes.

HG GLOBAL/BAM

BAM is domiciled in New York and was established to provide insurance on municipal bonds issued to support essential U.S. public purposes such as schools, utilities, core governmental functions and existing transportation facilities. Members of BAM’s senior management team have more than 25 years on average of experience in the bond insurance industry.
HG Global is domiciled in Bermuda and was established to fund the startup of BAM, and through its subsidiary, HG Re, to provide reinsurance to BAM. In 2012, HG Global was capitalized with $609 million to purchase surplus notes in BAM and to fund HG Re.
White Mountains believes that municipal bonds insured by BAM have strong appeal to retail investors, who buy smaller, less liquid issues, have less portfolio diversification and have fewer credit differentiation skills and analytical resources.  BAM focuses on underwriting small-to-medium sized investment grade bonds, primarily in the AA-, A and BBB categories. BAM seeks to provide insurance to the municipal bond market while building a relatively low risk insurance portfolio with conservative single risk limits (initially the aggregate par value of the insured bonds with a common revenue stream is limited to $100 million).
BAM launched in July 2012 after securing an “AA/stable” rating from Standard & Poor's (“AA” is the third highest of twenty-one financial strength ratings assigned by Standard & Poor's).  HG Global, together with its subsidiaries, funded the initial capitalization of BAM through the purchase of $503 million of BAM Surplus Notes.  BAM and HG Re entered into a first loss reinsurance treaty (“FLRT”), under which HG Re will provide first loss protection up to 15% of par outstanding on each bond insured by BAM in exchange for 60% of the premium, net of a ceding commission, charged by BAM. 

22


HG Re's obligations under the FLRT are satisfied by the assets in two collateral trusts: a Regulation 114 Trust and a Supplemental Trust.  Losses required to be reimbursed to BAM by HG Re are subject to an aggregate limit equal to the assets held in the collateral trusts at any point in time.  The Regulation 114 Trust target balance is equal to ceded unearned premiums and unpaid ceded loss and LAE expenses, if any.  The Supplemental Trust target balance is equal to approximately $400 million.  The collateral trust balances must be at target levels before excess capital can be distributed out of the Supplemental Trust to HG Re.  At any point in time, if the sum of the Regulation 114 Trust balance and the Supplemental Trust balance equal zero, BAM may choose to terminate the FLRT on a runoff basis. However, HG Re can elect to continue the FLRT by depositing into the Regulation 114 Trust assets with a fair market value not less than the greater of (i) $100 million or (ii) 10% of the then Regulation 114 Trust target balance.  At inception, the Supplemental Trust contained $300 million of BAM Surplus Notes and $100 million of cash and fixed income securities.  As the BAM Surplus Notes are repaid over time, the BAM Surplus Notes will be replaced in the Supplemental Trust by cash and fixed income securities.
The FLRT is perpetual with an initial term of 10 years. The FLRT can be amended after the first 10-year period and after each subsequent 5-year period on a prospective basis. If the parties are unable to mutually agree to amended terms, the dispute is resolved through arbitration, with the arbitrator determining amendments that would best achieve BAM and HG Global’s joint expectation of certain basic principles including maintenance of BAM’s rating, the provision to BAM of reliable first loss reinsurance, and HG Global achieving an equitable rate of return. Amended contract terms must be approved by the New York Department of Financial Services. Should BAM consider the amended terms to be unacceptable, it has the option to purchase HG Re, or cause another reinsurer to purchase HG Re, at fair value. Pursuant to the FLRT, BAM’s underwriting guidelines may only be amended with the consent of HG Re. In addition, HG Global has the right to designate two directors for election to BAM’s board of directors.
As of December 31, 2012, White Mountains owned 97.3% of HG Global's preferred equity and 88.7% of its common equity. At December 31, 2012, HG Global had $624 million of total assets and $623 million of shareholders' equity, $17 million of which is included in non-controlling interest. At December 31, 2012, BAM had $493 million of total assets and $(36) million of members’ equity, all of which is included in non-controlling interest.

OTHER OPERATIONS

White Mountains’ Other Operations segment consists of the Company and its intermediate holding companies, its wholly-owned investment management subsidiary (WM Advisors) and its variable annuity reinsurance business (WM Life Re), which is in runoff, as well as various other entities not included in other segments.

WM Advisors
WM Advisors is a registered investment adviser that manages White Mountains’ investments in fixed income and equity securities, including hedge funds and private equities. WM Advisors also has investment management agreements with third parties, most notably with Symetra Financial Corporation (“Symetra”). At December 31, 2012, WM Advisors had approximately $33.6 billion in assets under management, $6.2 billion of which related to consolidated subsidiaries of White Mountains.
WM Advisors has a sub-advisory agreement with Prospector Partners LLC (“Prospector”), a registered investment adviser, under which Prospector manages most of White Mountains’ publicly-traded common equity securities and convertible fixed maturity securities. At December 31, 2012, the value of White Mountains’ common equity and convertible fixed maturity securities managed by Prospector totaled $886 million, which represented 77% of White Mountains’ total common equity and convertible fixed maturity portfolio. Prospector also provides consulting and advisory services to White Mountains through a separate agreement on matters such as asset allocation, hedge fund and private equity investments, capital management and mergers and acquisitions.

WM Life Re
WM Life Re reinsures death and living benefit guarantees associated with certain variable annuities issued in Japan.  Sirius Group fronted the reinsurance contracts for and is 100% reinsured by WM Life Re. WM Life Re is in runoff.

23


WM Life Re has assumed the risk related to a shortfall between the account value and the guaranteed value that must be paid by the ceding company to an annuitant or to an annuitant’s beneficiary in accordance with the underlying annuity contracts.  The guaranteed value of the annuity contracts is equal to the initial single premium paid by the annuitant.  The annuity accounts are invested in four index funds: a Japanese government bond fund indexed to the Nomura Bond Performance Index (“Nomura BPI”) (roughly 35%), a foreign government bond fund indexed to the Citi World Group Government Bond Index, excluding Japan (“WGBI”) (roughly 35%), a Japanese equity fund indexed to the TOPIX Total Return Index (roughly 15%) and a foreign equity fund indexed to the MSCI Kokusai Total Return Index (roughly 15%).  The account is rebalanced monthly to maintain these same investment allocations. As of December 31, 2012, annuity contracts mature within 3 years on average (with a maximum of 3½ years and a minimum of 2½ years remaining).  The guarantee made by the ceding company to its annuitants was economically equivalent to guaranteeing that the underlying investment accounts would earn a return of approximately 2.7% per annum.  The average account value of annuity contracts covered by WM Life Re was approximately 104% of their guarantee value at the inception of the reinsurance contracts.  Accordingly, the guarantee made in WM Life Re’s contracts was economically equivalent to guaranteeing that the underlying investment accounts would earn a return of approximately 2.3% per annum.
WM Life Re reinsured ¥200 billion (approximately $1.7 billion at the then current exchange rate) of guarantees in September 2006 and an additional ¥56 billion (approximately $0.5 billion at the then current exchange rate) in March 2007.  WM Life Re has not subsequently written any additional business and the last policy reinsured under WM Life Re's existing contract will mature on June 30, 2016.  As of December 31, 2012, the total guarantee value was approximately ¥230.0 billion (approximately $2.7 billion at exchange rates on that date).  The average annual premium charged by WM Life Re under these contracts is equal to 1.11% times the total guarantee value.
WM Life Re uses derivative instruments, including put options, interest rate swaps, total return swaps on bond indices, forward contracts and futures contracts on major equity indices, currency pairs and government bonds, to mitigate the market risks associated with changes in the fair value of the reinsured variable annuity guarantees. WM Life Re measures its net exposure to changes in relevant interest rates, foreign exchange rates, implied volatilities and equity markets on a daily basis and adjusts its economic hedge positions within risk guidelines established by a risk committee that contains members of White Mountains’ and WM Life Re’s senior management. WM Life Re continually fair values its liability and the related hedge assets.  The guarantee is economically substantially similar to having sold put options on a basket of the four index funds. WM Life Re also monitors the effects of annuitant related experience against actuarial assumptions (surrender and mortality rates) on a weekly basis and adjusts relevant assumptions and economic hedge positions if required.
Under the terms of its reinsurance contracts, WM Life Re is required to hold eligible assets (generally cash, short-term investments, fixed income securities, and hedge assets such as options and futures) equal to the fair value of the liability, as defined in the reinsurance contracts, for the benefit of the cedant.  Increases in the fair value of the liability in excess of the increase in value of the hedge assets, such as occurs in the case of decreases in surrender assumptions or underperformance of the hedging portfolio, must therefore be funded on a current basis while the actual amounts that must be paid to settle the contracts may not be known and generally will not become payable for a number of years.  White Mountains contributed $25 million, $20 million and $45 million into WM Life Re during 2012, 2011 and 2010, respectively, to fulfill this requirement.
See “CRITICAL ACCOUNTING ESTIMATES - Fair Value Measurements” on page 90 for a discussion of the sensitivity of WM Life Re’s results to changes in market and annuitant-related variables.

Berkshire Exchange
On October 31, 2008, White Mountains completed the transaction with Berkshire Hathaway Inc. (“Berkshire”) that was announced on March 10, 2008, through which Berkshire exchanged substantially all of its 16.3% stake in White Mountains (1,634,921 of its 1,724,200 common shares) for 100% of a White Mountains subsidiary which held Commercial Casualty Insurance Company (“CCIC”), the International American Group, Inc. and $708 million in cash (the “Berkshire Exchange”). Upon the closing of the exchange transaction, CCIC and the International American Group, Inc. had a combined fair value of $85 million and a combined GAAP book value of $59 million.

DISCONTINUED OPERATIONS

OneBeacon
On October 17, 2012, one of OneBeacon's indirect wholly-owned subsidiaries, OneBeacon Insurance Group LLC, entered into the Runoff Transaction to sell the Runoff Business to Trebuchet US Holdings, Inc. (“Trebuchet”), a wholly-owned subsidiary of Armour Group Holdings Limited (together with Trebuchet, “Armour”). Pursuant to the terms of the agreement, at closing, OneBeacon will transfer to Trebuchet all of the issued and outstanding shares of common stock of certain legal entities that will contain the assets, liabilities (including gross and ceded loss reserves) and capital supporting the runoff business as well as certain elements of the runoff business infrastructure, including staff and office space. Additionally, as part of the Runoff Transaction, OneBeacon may provide financing in the form of surplus notes. The transaction is subject to regulatory approvals and is expected to close in the second half of 2013. As a result of the Runoff Transaction, the Runoff Business is reported as discontinued operations in White Mountains’ financial statements.

24


On February 22, 2012, OneBeacon completed the sale of AutoOne to Interboro Holdings, Inc. (“Interboro”). OneBeacon formed AutoOne in 2001 to provide products and services to automobile assigned risk markets primarily in New York and New Jersey. OneBeacon transferred to the buyer AutoOne Insurance Company (“AOIC”) and AutoOne Select Insurance Company (“AOSIC”), which contained the assets, liabilities, including loss reserves and unearned premiums, and capital supporting the AutoOne business, and transferred substantially all of the AutoOne infrastructure including systems and office space as well as certain staff. As a result of the sale, AutoOne is reported as discontinued operations in White Mountains’ financial statements.

Esurance
On October 7, 2011, White Mountains completed the sale of Esurance to Allstate for a cash payment of $1.01 billion, which was equal to $700 million plus the estimated pro forma tangible book value at closing of the legal entities sold of approximately $310 million. As a result of the sale, Esurance is reported as discontinued operations in White Mountains' financial statements.
Esurance Insurance wrote personal auto insurance in 30 states through its website and over the phone and also sold other lines of personal insurance for unaffiliated insurance companies. Esurance Insurance also wrote personal auto policies through select on-line agents and provided other insurance products through partnerships with industry leading online providers. The 30 states in which Esurance Insurance wrote business represent approximately 87% of the premium volume for the entire U.S. personal auto insurance market. AFI earned commissions by selling personal auto, homeowners, renters and condo insurance policies online and over the phone using a comparison quoting platform. AFI sold policies in 50 states and the District of Columbia for many insurance companies, including Esurance Insurance.
See Note 20—“Discontinued Operations” of the accompanying consolidated financial statements for details of amounts included in net assets held for sale, net income (loss) from discontinued operations and gains (losses) from sales of discontinued operations.

INVESTMENTS

White Mountains’ investment philosophy is to maximize long-term total returns (after-tax) while taking prudent levels of risk and maintaining a diversified portfolio.  Under White Mountains’ philosophy, each dollar of after-tax investment income or investment gains (realized or unrealized) is valued equally.
White Mountains’ investment portfolio mix as of December 31, 2012 consisted in large part of high-quality, short-duration, fixed maturity investments and short-term investments, but also included common equity securities, convertible fixed maturity securities and other long-term investments, such as hedge funds and private equities. White Mountains’ management believes that prudent levels of investments in common equity securities, convertible fixed maturity securities and other long-term investments are likely to enhance long-term after-tax total returns. See “Portfolio Composition” on page 60.
White Mountains’ overall fixed maturity investment strategy is to purchase securities that are attractively priced in relation to their investment risks. White Mountains also actively manages the average duration of the portfolio.  Duration is about 2.4 years including short-term investments and about 2.7 years excluding short-term investments at December 31, 2012.
Prospector’s equity investment strategy is to maximize risk-adjusted absolute return through investments in a variety of equity and equity-related instruments, using a bottom-up, value investing approach. Preservation of capital is of the utmost importance.  Prospector invests in the United States and other developed markets.

Prospector Funds
White Mountains owns approximately 71% of the limited partnership interests in Prospector Offshore Fund, Ltd. and approximately 72% of the limited partnership interests in Prospector Turtle Fund (collectively, the “Prospector Funds”).  These funds are managed by Prospector, a registered investment adviser, and are consolidated within White Mountains’ financial statements. The Prospector Funds are hedge funds that pursue investment opportunities in a variety of equity and equity-related instruments, chiefly in the financial services sector.
At December 31, 2012 and 2011, the Prospector Funds had $239 million and $217 million of total assets and accounted for $103 million and $98 million of White Mountains’ net assets.

Symetra
In 2004, White Mountains, Berkshire and several other private investors capitalized Symetra in order to purchase the life and investment operations of Safeco Corporation for $1.35 billion. The acquired companies focus mainly on group insurance, individual life insurance, structured settlements and retirement services. Symetra had an initial capitalization of approximately $1.4 billion, consisting of $1,065 million of common equity and $315 million of debt. White Mountains invested $195 million in Symetra in exchange for 17.4 million common shares, as adjusted for stock splits, of Symetra. In addition, White Mountains and Berkshire each received warrants to acquire an additional 9.5 million common shares of Symetra at $11.49 per share, as adjusted for stock splits.  One White Mountains designee and one member of White Mountains’ Board of Directors currently serves on Symetra’s seven member board of directors. White Mountains accounts for its investment in common shares of Symetra under the equity method and accounts for its Symetra warrants as a derivative investment at fair value.

25


In January 2010, Symetra completed an initial public offering at a price of $12 per share, whereby 25.3 million primary shares were sold to the public and 9.7 million secondary shares were sold by existing shareholders. White Mountains did not sell any of its shares of Symetra in the offering. As a result of the offering, White Mountains’ ownership in Symetra has decreased from 19% to 15% of the outstanding common shares of Symetra and from 24% to 20% of Symetra on a fully-converted basis including the warrants.
The following table presents the financial strength ratings assigned to Symetra’s principal insurance operating subsidiaries as of February 28, 2013:

Symetra’s total revenues and net income for the years ended December 31, 2012, 2011 and 2010 were $2,101 million and $205 million, $1,999 million and $200 million, and $1,879 million and $201 million. As of December 31, 2012 and 2011, Symetra had total assets of $29.5 billion and $28.2 billion and shareholders’ equity of $3.6 billion and $3.1 billion. Symetra’s shareholders’ equity excluding unrealized gains (losses) from its fixed maturity investments was $2.3 billion and $2.1 billion at December 31, 2012 and 2011.
As of December 31, 2012 and 2011, White Mountains’ investment in Symetra common shares was $288 million (excluding $63 million of pre-tax equity in unrealized gains from Symetra’s fixed maturity investments) and $261 million. As of December 31, 2012 and 2011, White Mountains’ investment in Symetra warrants was $30 million and $13 million. Since inception, White Mountains has received cash dividends from Symetra of $58 million on its common share investment and $32 million on its warrant investment.
During the fourth quarter of 2011, White Mountains recorded a GAAP other-than-temporary impairment write-down on its investment in Symetra common shares. White Mountains concluded that the accounting impairment on its investment in Symetra common shares arose due to the prolonged low interest rate environment in which life insurance companies currently operate and not due to reasons specific to Symetra. As a result, White Mountains does not believe that the accounting impairment equates to an impairment in Symetra’s long-term intrinsic business value. See CRITICAL ACCOUNTING ESTIMATES — White Mountains’ Investment in Symetra Common Shares on page 100 for a complete discussion of the methodology used to determine the GAAP other-than-temporary impairment on Symetra at December 31, 2011.

REGULATION

United States
White Mountains’ U.S.-based insurance and reinsurance operating subsidiaries are subject to regulation and supervision in each of the states where they are domiciled and licensed to conduct business. Generally, state regulatory authorities have broad supervisory and administrative powers over such matters as licenses, standards of solvency, premium rates, policy forms, investments, security deposits, methods of accounting, form and content of financial statements, reserves for unpaid loss and LAE, reinsurance, minimum capital and surplus requirements, dividends and other distributions to shareholders, periodic examinations and annual and other report filings. In general, such regulation is for the protection of policyholders rather than shareholders. White Mountains believes that it is in compliance with all applicable laws and regulations pertaining to its business that would have a material effect on its financial position in the event of non-compliance.
Most states have laws that establish standards for current, as well as continued, state accreditation. In addition, the National Association of Insurance Commissioners (“NAIC”) has risk-based capital (“RBC”) standards for property and casualty insurers as a means of monitoring certain aspects affecting the overall financial condition of insurance companies. The current RBC ratios of White Mountains’ active U.S.-based insurance and reinsurance operating subsidiaries are satisfactory and such ratios are not expected to result in any adverse regulatory action. White Mountains is not aware of any current recommendations by regulatory authorities that would be expected to have a material effect on its results of operations or liquidity.

26


The NAIC’s Annual Financial Reporting Model Regulation, or the Model Audit Rule (“MAR”), includes provisions that are similar to certain Sarbanes-Oxley requirements for public companies and requires certain insurance companies to appoint audit committees to oversee accounting and financial reporting processes as well as the audit of the statutory financial statements of the insurer.  Audit committees also are required to appoint independent auditors, among other things.  The appointed audit committee receives reports regarding significant deficiencies, material weaknesses and solvency concerns at the insurance company level.  Certain insurance companies are also required to annually file a management report on internal control over financial reporting.
As a condition of its license to do business in certain states, White Mountains’ U.S.-based insurance and reinsurance operating subsidiaries are required to participate in mandatory shared market mechanisms. Each state dictates the types of insurance and the level of coverage that must be provided. The most common type of shared market mechanism in which White Mountains is required to participate is an assigned risk plan. Many states operate assigned risk plans. These plans require insurers licensed within the applicable state to accept the applications for insurance policies of customers who are unable to obtain insurance in the voluntary market. The total number of such policies an insurer is required to accept is based on its market share of voluntary business in the state. Underwriting results related to assigned risk plans are typically adverse. Accordingly, White Mountains may be required to underwrite policies with a higher risk of loss than it would otherwise accept.
Reinsurance facilities are another type of shared market mechanism. Reinsurance facilities require an insurance company to accept all applications submitted by certain state designated agents. The reinsurance facility then allows the insurer to cede some of its business to the reinsurance facility so that the facility will reimburse the insurer for claims paid on ceded business. Typically, however, reinsurance facilities operate at a deficit, which is funded through assessments against the same insurers. As a result, White Mountains could be required to underwrite policies with a higher risk of loss than it would otherwise voluntarily accept.
Many states have laws and regulations that limit an insurer’s ability to exit a market. For example, certain states prohibit an insurer from withdrawing from one or more lines of insurance business in the state, unless the state regulators approve the company’s withdrawal plans. State regulators may refuse to approve such plans on the grounds that they could lead to market disruption. Such laws and regulations may restrict White Mountains’ ability to exit unprofitable markets.
Nearly all states have insurance laws requiring property and casualty insurance companies to file price schedules, policy or coverage forms, and other information with the state’s regulatory authority. In most cases, such price schedules and/or policy forms must be approved prior to use. While pricing laws vary from state to state, their objectives are generally to ensure that prices are adequate, not excessive and not discriminatory.
White Mountains’ U.S.-based insurance and reinsurance operating subsidiaries are subject to state laws and regulations that require investment portfolio diversification and that limit the amount of investment in certain categories. Non-compliance may cause non-conforming investments to be non-admitted in measuring statutory surplus and, in some instances, may require divestiture. White Mountains’ investment portfolio at December 31, 2012 complied with such laws and regulations in all material respects.
One of the primary sources of cash inflows for the Company and certain of its intermediate holding companies is dividends received from its insurance and reinsurance operating subsidiaries. Under the insurance laws of the states under which White Mountains’ U.S.-based insurance and reinsurance operating subsidiaries are domiciled, an insurer is restricted with respect to the timing or the amount of dividends it may pay without prior approval by regulatory authorities. See “Dividend Capacity” on page 64 for further discussion.
White Mountains is subject to regulation under certain state insurance holding company acts. These regulations contain reporting requirements relating to the capital structure, ownership, financial condition and general business operations of White Mountains’ insurance and reinsurance operating subsidiaries. These regulations also contain special reporting and prior approval requirements with respect to certain transactions among affiliates. Since the Company is an insurance holding company, the domiciliary states of its insurance and reinsurance operating subsidiaries impose regulatory application and approval requirements on acquisitions of White Mountains’ common shares which may be deemed to confer control over those subsidiaries, as that concept is defined under the applicable state laws. Acquisition of 10% of White Mountains’ common shares, or in some states as little as 5%, may be deemed to confer control under the insurance laws of some jurisdictions, and the application process for approval can be extensive and time consuming.
While the federal government does not directly regulate the insurance business, federal legislation and administrative policies affect the insurance industry. In addition, legislation has been introduced from time to time in recent years that, if enacted, could result in the federal government assuming a more direct role in the regulation of the insurance industry. For example, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) was enacted in 2010 and created the Federal Insurance Office (“FIO”) within the Treasury Department, which is responsible for gathering information and monitoring the insurance industry to identify gaps in the regulation of insurers that could contribute to a systemic crisis in the insurance industry or U.S. financial system. The FIO can also recommend changes to state insurance laws and regulations. Although the deadline was in January 2012, the FIO’s “Study and Report on the Regulation of Insurance” in the United States has not yet been released. White Mountains cannot predict whether the FIO will recommend any changes or whether states will adopt any such changes.

27


In addition, the U.S. government enacted the Terrorism Act in 2002 and established a federal “backstop” for commercial property and casualty losses, including workers compensation, resulting from acts of terrorism by or on behalf of any foreign person or foreign interest.  In December of 2007, the Terrorism Act was extended until December 31, 2014. As extended, the law now covers domestic acts of terrorism. In exchange for this “backstop”, primary insurers are required to make coverage available to commercial insureds for losses from acts of terrorism as specified in the Terrorism Act. OneBeacon is actively complying with the requirements of the Terrorism Act in order to ensure its ability to be reimbursed by the federal government for any losses it may incur as a result of future terrorist acts. (See “ONEBEACON — Terrorism” on page 10 for a further discussion of the Terrorism Act). A number of additional enacted and pending legislative measures could lead to increased consolidation and increased competition for business and for capital in the financial services industry. White Mountains cannot predict whether any state or federal measures will be adopted to change the nature or scope of the regulation of the insurance business or what effect such measures may have on its insurance and reinsurance operations. The Terrorism Act expires in 2014, and there can be no assurance that it will be extended.
The NAIC’s 2010 amendment to the Model Insurance Company Holding Company System Regulatory Act (the “Model Law”) enhances the authority of state insurance regulators in the adopting state to regulate insurers as well as their affiliated entities, on an enterprise risk basis. The amendment to the Model Law requires the ultimate controlling person in an insurer’s holding company structure to identify and report to state insurance regulators material risks within the structure that could pose enterprise risk to the insurer. The amendment to the Model Law will need to be adopted by individual state legislatures before they become binding on any given state. States may also deviate from these Model Law revisions as states differ in their approaches on several requirements. White Mountains cannot predict whether states will adopt the amendment to the Model Law, or if adopted, whether the amendment will differ from the Model Law.
Environmental cleanup of polluted waste sites is subject to both federal and state regulation. The Comprehensive Environmental Response Compensation and Liability Act of 1980 (“Superfund”) and comparable state statutes govern the cleanup and restoration of waste sites by potentially responsible parties (“PRPs”). These laws can impose liability for the entire cost of clean-up upon any PRP, regardless of fault. The insurance industry in general is involved in extensive litigation regarding coverage issues arising out of the cleanup of waste sites by insured PRPs and as a result has disputed many such claims. From time to time, comprehensive Superfund reform proposals are introduced in Congress, but none has yet been enacted. At this time, it remains unclear as to whether Superfund reform legislation will be enacted or that any such legislation will provide for a fair, effective and cost-efficient system for settlement of Superfund related claims. The NICO Cover includes coverage for such exposures at OneBeacon; however, there can be no assurance that the coverage provided under the NICO Cover will ultimately prove to be adequate.

Europe
Sweden
Sirius International is subject to regulation and supervision by the Swedish Financial Supervisory Authorities (the “Swedish FSA”). As Sweden is a member of the European Union (the “EU”), the Swedish FSA supervision is recognized across all locations within the EU. Generally, the Swedish FSA has broad supervisory and administrative powers over such matters as licenses, standards of solvency, investments, methods of accounting, form and content of financial statements, minimum capital and surplus requirements, and annual and other report filings. In general, such regulation is for the protection of policyholders rather than shareholders. White Mountains believes that it is in compliance with all applicable laws and regulations pertaining to its business that would have a material effect on its financial position in the event of non-compliance.
In accordance with provisions of Swedish law, Sirius International is permitted to transfer up to the full amount of its pre-tax income, subject to certain limitations, into an untaxed reserve referred to as a safety reserve, which equaled SEK 9.6 billion or $1.5 billion at December 31, 2012. Under GAAP, an amount equal to the safety reserve, net of a related deferred tax liability established at the Swedish tax rate, is classified as shareholder’s equity. The tax rate in effect on December 31, 2011 was 26.3%. The tax rate utilized on December 31, 2012 was the new Swedish tax rate of 22.0%. Generally, this deferred tax liability is only required to be paid by Sirius International if it fails to maintain predetermined levels of premium writings and loss reserves in future years. As a result of the indefinite deferral of these taxes, Swedish regulatory authorities do not apply any taxes to the safety reserve when calculating solvency capital under Swedish insurance regulations. Accordingly, under local statutory requirements, an amount equal to the deferred tax liability on Sirius International’s safety reserve ($327 million at December 31, 2012) is included in solvency capital. Access to the safety reserve is restricted to coverage of reinsurance losses.  Access for any other purpose requires the approval of Swedish regulatory authorities.  Similar to the approach taken by Swedish regulatory authorities, most major rating agencies generally include the $1.5 billion balance of the safety reserve, without any provision for deferred taxes, in Sirius International’s regulatory capital when assessing Sirius International’s financial strength.


28


United Kingdom
The financial services industry in the United Kingdom is regulated by the Financial Services Authority (“UK FSA”). The UK FSA regulates insurers, insurance intermediaries and Lloyd’s.  The UK FSA and Lloyd’s have common objectives in ensuring that the Lloyd’s market is appropriately regulated. Lloyd’s is required to implement certain rules prescribed by the UK FSA by the powers it has under the Lloyd’s Act of 1982 (“Lloyd’s Act”) relating to the operation of the Lloyd’s market. In addition, each year the UK FSA requires Lloyd’s to satisfy an annual solvency test that measures whether Lloyd’s has sufficient assets in the aggregate to meet all the outstanding liabilities of its members.
Lloyd’s permits its corporate and individual members (“Members”) to underwrite insurance risks through Lloyd’s syndicates. Members of Lloyd’s may participate in a syndicate for one or more underwriting years by providing capital to support the syndicate’s underwriting. All syndicates are managed by Lloyd’s approved managing agents. Managing agents receive fees and profit commissions in respect of the underwriting and administrative services they provide to the syndicates. Lloyd’s prescribes, in respect of its managing agents and Members, certain minimum standards relating to their management and control, solvency and various other requirements.
Sirius Group participates in the Lloyd’s market through the 100% ownership of White Mountains Sirius Capital Ltd., a Lloyd’s corporate Member, which in turn provides underwriting capacity to Syndicate 1945. Syndicate 1945 commenced underwriting on July 1, 2011 and Asta Capital Ltd. is its managing agent.  The Syndicate 1945 stamp capacity for 2013 is £93 million ($150 million based on the December 31, 2012 GBP to USD exchange rate). Stamp capacity is a measure of the amount of net premium (premiums written less acquisition costs) that a syndicate is authorized by Lloyd’s to write.
A corporate Member of Lloyd’s is bound by the rules of the Society of Lloyd’s which are prescribed by the by-laws and requirements of the Council of Lloyd’s under powers conferred by the Lloyd’s Act. These rules govern Sirius Group’s corporate Member participation in Syndicate 1945 and among other things prescribe Syndicate 1945’s membership subscription and level of contribution to the Lloyd’s Central Fund (“Central Fund”).
The underwriting capacity of a Member of Lloyd’s must be supported by providing a deposit in the form of cash, securities or letters of credit (“Funds at Lloyd’s”) in an amount to be determined pursuant to the capital adequacy requirements set by the UK FSA. The amount of such deposit is calculated for each member through the completion of an annual capital adequacy exercise. Pursuant to these requirements Lloyd’s must demonstrate that each Member has sufficient assets to meet its underwriting liabilities plus a required solvency margin.
At the syndicate level, managing agents are required to calculate the capital resources requirement of the members of each syndicate they manage. They perform an Individual Capital Assessment (“ICA”) in accordance with the UK FSA criteria. During the ICA process the managing agent evaluates the risks faced by the syndicate, including insurance, operational, market, liquidity, and credit risks and assesses the amount of capital syndicate Members should hold against that risk. The ICA is reviewed annually by Lloyd’s. Each syndicate is also required to submit a business plan to Lloyd’s on an annual basis, which is subject to the review and approval of the Lloyd’s Performance Management Directorate.
Lloyd’s has wide discretionary powers to regulate a Member’s underwriting. For example, Lloyd’s may change the way that syndicate expenses are allocated or vary the Funds at Lloyd’s investment criteria. Any such change may affect the Member’s return on investment. If a Member is unable to pay its obligations to policyholders, such obligations may be payable by the Central Fund, which, in many ways, resembles a state guaranty fund in the United States. If Lloyd’s determines that the Central Fund needs to be increased, it may levy premiums on current Lloyd’s Members. The Council of Lloyd’s has discretion to assess up to 3% of a Member’s underwriting capacity in any one year as a Central Fund contribution.

Solvency II
The European Commission, which is the executive body of the European Union, has proposed a directive on insurance regulation and solvency requirements known as Solvency II. The European Insurance and Occupational Pensions Authority (“EIOPA”) is an independent advisory body to the European Parliament and the Council of the European Union, and EIOPA is drafting the guidelines and standards to support the implementation of Solvency II. The Omnibus II Directive will set the date of entry into force of Solvency II. Many, including EIOPA have in the past adopted a working assumption for the timeline of Solvency II, setting January 1, 2014 as a basis for the entry into force of Solvency II. However, a definitive effective date for Solvency II regulation has not yet been established, but implementation could occur in the next couple of years. Sirius International is continuing to prepare for compliance with the upcoming Solvency II regulation, despite the uncertainty of the implementation date.

29


Solvency II has set the framework for the next generation of supervisory rules for insurance and reinsurance companies in the EU, and will impose economic risk-based solvency requirements across all EU Member States.  The aim of the Solvency II framework is to ensure that insurance and reinsurance undertakings are financially sound and can withstand adverse events in order to protect policyholders and the stability of the financial system as a whole. In addition to quantitative requirements, such as capital requirements (Pillar 1), insurance and reinsurance companies will be required to meet qualitative requirements relating to governance and risk-management (Pillar 2), as well as to regularly disclose information to supervisors and to the public (Pillar 3). Sirius International and its wholly-owned subsidiary, Sirius America, will be required to comply with Solvency II requirements. In addition, it is possible that the NAIC could adopt part or all of Solvency II, including minimum capital requirements that could be in excess of the current minimum capital requirements for White Mountains’ U.S.-based insurance and reinsurance subsidiaries established by state regulations.  If the NAIC adopted Solvency II, White Mountains’ U.S.-based insurance and reinsurance operating subsidiaries’ businesses and results of operations could be materially impacted.

Bermuda
Insurance Regulation
The Insurance Act 1978 of Bermuda and related regulations, as amended (the “Insurance Act”), regulates the insurance businesses of the Bermuda branch of Sirius International, Star Re Ltd., White Shoals, WM Life Re and HG Re, and provides that no person may carry on any insurance business in or from within Bermuda unless registered as an insurer under the Insurance Act by the Bermuda Monetary Authority (“BMA”). The BMA, in deciding whether to grant registration, has broad discretion to act as it thinks fit in the public interest. The BMA is required by the Insurance Act to determine whether the applicant is a fit and proper body to be engaged in the insurance business and, in particular, whether it has, or has available to it, adequate knowledge and expertise to operate an insurance business. In addition, the BMA is required by the Insurance Act to determine whether a person who proposes to control 10 percent, 20 percent, 33 percent or 50 percent (as applicable) of the voting powers of a Bermuda registered insurer or its parent company is a fit and proper person to exercise such degree of control.
The continued registration of an applicant as an insurer is subject to the applicant complying with the terms of its registration and such other conditions as the BMA may impose from time to time. The Insurance Act also grants to the BMA powers to supervise, investigate and intervene in the affairs of insurance companies.
The Insurance Act imposes solvency and liquidity standards on Bermuda insurance companies, as well as auditing and reporting requirements. White Mountains believes that it is in compliance with all applicable laws and regulations pertaining to its business that would have a material effect on its financial position in the event of non-compliance.

Certain Other Bermuda Law Considerations
The Company is an exempted company organized under the Companies Act 1981 of Bermuda (the “Companies Act”). As a result, the Company is required to comply with the provisions of the Companies Act regulating the payment of dividends and making of distributions from contributed surplus. A company is prohibited from declaring or paying a dividend, or making a distribution out of contributed surplus, if there are reasonable grounds for believing that:

(1)
the company is, or would after the payment be, unable to pay its liabilities as they become due; or
(2)
the realizable value of the company’s assets would thereby be less than its liabilities.

Under the Company’s bye-laws, each common share is entitled to dividends if, and when, dividends are declared by its board of directors, subject to any preferred dividend rights of the holders of any preference shares. Issued share capital is the aggregate par value of the company’s issued shares, and the share premium account is the aggregate amount paid for issued shares over and above their par value. Share premium accounts may be reduced in certain limited circumstances. In addition, the Companies Act regulates return of capital, reduction of capital and any purchase or redemption of shares by the Company.
Although the Company is incorporated in Bermuda, it has been designated as a non-resident of Bermuda for exchange control purposes by the BMA. Pursuant to its non-resident status, the Company may hold any currency other than Bermuda dollars and convert that currency into any other currency, other than Bermuda dollars, without restriction.

30


Shares may be offered or sold in Bermuda only in compliance with the provisions of the Investment Business Act 2003 and the Exchange Control Act 1972, and related regulations of Bermuda which regulate the sale of securities in Bermuda. In addition, specific permission is required from the BMA pursuant to the provisions of the Exchange Control Act 1972 and related regulations, for all issuances and transfers of securities of Bermuda companies, other than in cases where the BMA has granted a general permission. The BMA in its policy dated June 1, 2005 provides that where any equity securities, including the Company’s common shares, of a Bermuda company are listed on an appointed stock exchange, general permission is given for the issue and subsequent transfer of any securities of a company from and/or to a non-resident, for as long as any equity securities of such company remain so listed. The New York Stock Exchange is deemed to be an appointed stock exchange under Bermuda law. Notwithstanding the above general permission, the BMA has granted the Company permission to, subject to its common shares being listed on an appointed stock exchange, (a) issue and transfer its shares, up to the amount of its authorized capital from time to time, to persons resident and non-resident of Bermuda for exchange control purposes; (b) issue and transfer options, warrants, depositary receipts, rights, and other securities; and (c) issue and transfer loan notes and other debt instruments and options, warrants, receipts, rights over loan notes and other debt instruments to persons resident and non-resident of Bermuda for exchange control purposes.
Under Bermuda law, exempted companies are companies formed for the purpose of conducting business outside Bermuda from a principal place in Bermuda. As an exempted company, the Company may not, without the express authorization of the Bermuda legislature or under a license granted by the Bermuda Minister of Finance, participate in various specified business transactions, including

the acquisition or holding of land in Bermuda, except land held by way of lease or tenancy agreement which is required for the Company’s business and held for a term not exceeding 50 years, or which is used to provide accommodation or recreational facilities for the Company’s officers and employees and held with the consent of the Bermuda Minister of Finance, for a term not exceeding 21 years;
the taking of mortgages on land in Bermuda in excess of $50,000;
the acquisition of any bonds or debentures secured by any land in Bermuda, other than certain types of Bermuda government or public authority securities; or
subject to some exceptions, the carrying on of business of any kind in Bermuda for which the Company is not licensed in Bermuda.

Under Bermuda law, non-Bermudians (other than spouses of Bermudians) may not engage in any gainful occupation in Bermuda without an appropriate governmental work permit. Work permits may be granted or extended by the Bermuda government upon showing that, after proper public advertisement in most cases, no Bermudian (or spouse of a Bermudian) is available who meets the minimum standard requirements for the advertised position. The Bermuda government’s policy limits the duration of work permits to six years, with certain exemptions for key employees.

RATINGS

Insurance and reinsurance companies are evaluated by various rating agencies in order to measure each company’s financial strength. Higher ratings generally indicate financial stability and a stronger ability to pay claims. White Mountains believes that strong ratings are important factors in the marketing of insurance and reinsurance products and services to agents and consumers and ceding companies.
The following table presents the financial strength ratings assigned to White Mountains’ principal insurance and reinsurance operating subsidiaries as of February 28, 2013:

Following OneBeacon's announcement of the Runoff transaction, A.M. Best, Fitch, Moody's and Standard & Poor's each issued a press release regarding the ratings implications. A.M. Best placed the Runoff Subsidiaries under review with negative implications; Fitch placed the Runoff Subsidiaries on credit watch negative; and Moody's assigned a negative outlook. Standard & Poor's downgraded and subsequently, at the request of OneBeacon, withdrew its rating on the Runoff Subsidiaries. All four ratings agencies affirmed the ratings of the Ongoing Subsidiaries with stable Outlook.

EMPLOYEES

As of December 31, 2012, White Mountains employed approximately 1,700 people (consisting of 45 people at the Company, its intermediate holding companies, and HG Global, 1,200 people at OneBeacon, 418 people at Sirius Group, 38 people at WM Advisors and 8 people at WM Life Re). Management believes that White Mountains has satisfactory relations with its employees.

Item 1A.  Risk Factors
The information contained in this report may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. SeeFORWARD-LOOKING STATEMENTS(page 102) for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements. The Company’s actual future results and trends may differ materially depending on a variety of factors including, but not limited to, the risks and uncertainties discussed below.

Our investment portfolio may suffer reduced returns or losses which could adversely affect our results of operations and financial condition. Adverse changes in interest rates, foreign currency exchange rates, equity markets, debt markets or market volatility could result in significant losses to the fair value of our investment portfolio and could generate significant losses in our life reinsurance business.
Our investment portfolio consists of fixed maturity securities, convertible fixed maturity securities, short-term investments, common equity securities and other long-term investments such as hedge funds and private equities. We invest to maximize long-term after-tax total risk-adjusted return subject to our investment guidelines and various regulatory restrictions. However, investing entails substantial risks. We cannot assure you that we will achieve our investment objectives, and our investment performance may vary substantially over time. Investment returns are an important part of our strategy to grow adjusted book value per share, and fluctuations in the fixed income or equity markets could impair our results of operations and financial condition. Investments generate both income, consisting primarily of interest earned on fixed maturity investments and dividends earned on equity securities, and realized and unrealized investment gains on securities.
Both the investment income we generate and the fair market value of our investment portfolio are affected by general economic and market conditions, including fluctuations in interest rates, foreign currency exchange rates, debt market levels, equity market levels and market volatility. Interest rates are highly sensitive to many factors, including governmental monetary policies, domestic and international economic and political conditions and other factors beyond our control. Although we attempt to manage the risks of changes in interest rates, we may not be able to do so. In particular, a significant increase in interest rates could result in significant losses in the fair value of our investment portfolio and, consequently, could have an adverse effect on our results of operations and financial condition. We are exposed to changes in equity markets. A significant decline in the equity markets such as that experienced from September 2008 to March 2009 could have a material adverse effect on our results of operations and financial condition. Because a portion of our investment portfolio is invested in securities denominated in currencies other than U.S. dollar, the value of our portfolio is sensitive to changes in foreign currency rates. We are also exposed to changes in the volatility levels of various investment markets. The underlying conditions are outside of our control and could adversely affect the value of our investments and our results of operations and financial condition.
Our life reinsurance business has reinsured the risk related to a shortfall between the account value and the guaranteed value that must be paid in respect of certain Japanese variable annuity contracts. We use derivative instruments to mitigate the market risks associated with changes in the fair value of these guarantees.  These derivative instruments include put options, interest rate swaps, total return swaps and futures contracts on major equity indices, currency pairs and government bonds. However, these derivatives may not fully mitigate our exposure to the changes in the fair value of the guarantees.  For example, WM Life Re reported significant losses in 2008 because the increase in the fair value of its liabilities exceeded the increase in the fair value of the related derivative instruments.
The fair value of our life reinsurance contracts and the related derivative instruments is significantly affected by general economic and market conditions such as equity market returns and volatility, interest rate fluctuations and foreign currency exchange rates.  These conditions are outside of our control and could generate significant losses that would adversely affect our results of operations and financial condition.

Unpredictable catastrophic events could adversely affect our results of operations and financial condition.
We write insurance and reinsurance policies that cover losses from catastrophic events. Our property lines policies cover unpredictable natural and other disasters, such as hurricanes, windstorms, earthquakes, floods, fires and explosions. In recent years, the frequency of major catastrophes has increased.  We have significant exposure to a major earthquake or series of earthquakes in California, the Midwestern United States, Japan or Latin America and to windstorm damage in Northern Europe, the Northeast United States, the United States Atlantic Coast (i.e., Massachusetts to Florida) and the United States Gulf Coast (i.e., Florida to Texas) regions. In addition, we are exposed to losses from terrorist attacks, such as the attacks on the United States on September 11, 2001. We are also exposed to losses caused by the same types of catastrophic events in other lines of business such as marine, aviation, trade credit and accident and health.
The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area affected by the event and the severity of the event. Increases in the value and concentration of insured property or insured employees, the effects of inflation, changes in cyclical weather patterns and increased terrorism may increase the frequency and/or severity of claims from catastrophic events in the future. Claims from catastrophic events could materially adversely affect our results of operations and financial condition. Our ability to write new insurance and reinsurance policies could also be impacted as a result of corresponding reductions in our capital levels.

33


We seek to manage our exposure to catastrophic losses by limiting the aggregate insured value of policies in geographic areas with exposure to catastrophic events by estimating a PML for many different catastrophe scenarios and by buying reinsurance. To manage and analyze aggregate insured values and PML, we use a variety of tools, including external and internal catastrophe modeling software packages. Our estimates of PML are dependent on many variables, including assumptions about the demand surge and storm surge, loss adjustment expenses, insurance-to-value and storm intensity in the aftermath of weather- related catastrophes utilized to model the event, the relationship of the actual event to the modeled event and the quality of data provided to us by ceding companies (in the case of our reinsurance operations). Accordingly, if our assumptions about the variables are incorrect, the losses we might incur from an actual catastrophe could be materially higher than our expectation of losses generated from modeled catastrophe scenarios and our results of operations and financial condition could be materially adversely affected.

We may not maintain favorable financial strength or creditworthiness ratings which could adversely affect our ability to conduct business.
Third-party rating agencies assess and rate the financial strength, including claims-paying ability, of insurers and reinsurers. These ratings are based upon criteria established by the rating agencies and are subject to revision at any time at the sole discretion of the agencies. Some of the criteria relate to general economic conditions and other circumstances outside the rated company’s control. These financial strength ratings are used by policyholders, agents and brokers as an important means of assessing the suitability of insurers and reinsurers as business counterparties and have become an increasingly important factor in establishing the competitive position of insurance and reinsurance companies. These financial strength ratings do not refer to our ability to meet non-insurance obligations and are not a recommendation to purchase or discontinue any policy or contract issued by us or to buy, hold or sell our securities. The maintenance of an “A-” or better financial strength rating from A.M. Best and/or Standard & Poor’s is particularly important to our ability to write new or renewal property and casualty insurance and reinsurance business in most markets, while the maintenance of an “AA” or better financial strength rating from Standard and Poor’s is particularly important to BAM’s ability to write municipal bond insurance.  General creditworthiness ratings are used by existing or potential investors to assess the likelihood of repayment on a particular debt issue. The maintenance of an investment grade creditworthiness rating (e.g., “BBB-” or better from Standard & Poor’s, “Baa3” or better from Moody’s and “BBB-” or better from Fitch) is particularly important to our ability to raise new debt with acceptable terms.  We believe that strong creditworthiness ratings are important factors that provide better financial flexibility when issuing new debt or restructuring existing debt.
Rating agencies periodically evaluate us to confirm that we continue to meet the criteria of the ratings previously assigned to us. See “RATINGS” on page 32 for a summary of financial strength ratings on our significant insurance and reinsurance operating subsidiaries. A downgrade, withdrawal or negative watch/outlook of our financial strength ratings could severely limit or prevent our operating subsidiaries from writing new policies or renewing existing policies, which could have a material adverse effect on our results of operations and financial condition. A downgrade, withdrawal or negative watch/outlook of our creditworthiness ratings could limit our ability to raise new debt or could make new debt more costly and/or have more restrictive conditions.
Additionally, some of Sirius Group’s assumed reinsurance contracts contain optional cancellation, commutation and/or funding provisions that would be triggered if A.M. Best and/or Standard & Poor’s were to downgrade the financial strength ratings of Sirius Group’s significant reinsurance operating subsidiaries ratings below “A-”. A client may choose to exercise these rights depending on, among other things, the reasons for such a downgrade, the extent of the downgrade, the prevailing market conditions, the degree of unexpired coverage, and the pricing and availability of replacement reinsurance coverage. We cannot predict in advance how many of our clients would actually exercise such rights in the event of such a downgrade but widespread exercise of these options could be materially adverse.
 
There is no certainty that the Runoff Transaction will close. 
 Consummation of the sale of the OneBeacon's Runoff Business pursuant is subject to conditions, primarily regulatory approval, that are outside of the control of the parties. There can be no assurance as to whether or when such conditions may be satisfied and a closing would occur. If the Runoff Transaction does not close, there can be no assurance that we will effectively manage the Runoff Business in the future.

The property and casualty insurance and reinsurance industries are highly competitive and cyclical and we may not be able to compete effectively in the future.
The property and casualty insurance and reinsurance industries are highly competitive and have historically been cyclical, experiencing periods of severe price competition and less selective underwriting standards (“soft markets”) followed by periods of relatively high prices and more selective underwriting standards (“hard markets”). In general terms, OneBeacon competes in one or more of its businesses with most of the large multi-line insurance companies, such as ACE, AIG, Chubb Group, CNA, Liberty Mutual, Travelers and Zurich Insurance Group. OneBeacon also competes with most of the specialty companies, such as Allied World Assurance Company, HCC Insurance Holdings, Inc., Ironshore Inc., Markel Corporation, RLI Corp. and W.R. Berkley Corporation. Lastly, OneBeacon competes in certain of its businesses with various local and regional insurance companies. Sirius Group competes with numerous reinsurance companies throughout the world, including Allied World Assurance Company Holdings AG, Arch Capital Group Ltd., Aspen Insurance Holdings Ltd., Axis Capital Holdings, Ltd., Endurance Specialty Holdings Ltd., Everest Re Group, Ltd., General Reinsurance Corporation, Hannover Ruckversicherung AG, Montpelier Re Holdings, Ltd., Munich Re Group, Odyssey Re Holdings Corporation, Partner Re Ltd., Platinum Underwriters Holdings Ltd., Renaissance Re Holdings Ltd., Scor Global P&C, Swiss Re Group, Transatlantic Holdings, Inc., Validus Holdings, Ltd. and XL Capital Ltd. Many of these competitors have greater resources than we do, have established long-term and continuing business relationships throughout the insurance and reinsurance industries and may have higher financial strength ratings, which can be a significant competitive advantage for them.
OneBeacon offers its products through a number of distribution partners, consisting of independent agents, regional and national brokers, wholesalers and MGAs. Many of OneBeacon’s distribution partners offer insurance products sold by other insurance companies in addition to OneBeacon’s insurance products.  We could be adversely affected if these distribution partners place more of their business with other insurance companies as a result of price competition or other factors.  Additionally, OneBeacon’s distribution partners compete with other independent agents, regional and national brokers, wholesalers and MGAs to place insurance products.  We could be adversely affected if OneBeacon’s distribution partners are unable to maintain a competitive position in their respective markets.
Soft primary insurance market conditions could lead to a significant reduction in reinsurance premium rates, less favorable contract terms and fewer submissions for our reinsurance underwriting capacity. The supply of reinsurance is also related to the level of reinsured losses and the level of industry capital which, in turn, may fluctuate in response to changes in rates of return earned in the reinsurance industry. As a result, the reinsurance business historically has been a cyclical industry characterized by periods of intense price competition due to excess underwriting capacity as well as periods when shortages of capacity permitted improvements in reinsurance rate levels and terms and conditions. For example, the industry experienced soft casualty market conditions of lower prices and less favorable terms from 1997 to 2001 during which profitability suffered, while the losses incurred from the terrorist attacks of September 11, 2001 and the 2005 U.S. hurricanes triggered price increases. In addition, in recent years the persistent low interest rate environment and ease of entry into the reinsurance sector has led to increased competition from third party capital in the property catastrophe excess reinsurance line. This alternative capital provides collateralized property catastrophe protection in the form of catastrophe bonds, industry loss warranties, sidecars and other vehicles that facilitate the ability for non-reinsurance entities, such as hedge funds and pension funds, to compete for property catastrophe excess reinsurance business outside of the traditional treaty market. We have observed reduced pricing and/or reduced shares in certain property catastrophe excess reinsurance markets as a result.
We expect to continue to experience the effects of the insurance and reinsurance industries’ cyclicality.  If we are unable to maintain our competitive position throughout soft and hard market cycles, our insurance and reinsurance businesses may be adversely affected and we may not be able to compete effectively in the future.

Our loss and loss adjustment expense reserves may be inadequate to cover our ultimate liability for losses and as a result our financial results could be adversely affected.
We are required to maintain adequate reserves to cover our estimated ultimate liabilities for loss and loss adjustment expenses. Loss and LAE reserves are typically comprised of (1) case reserves for claims reported and (2) IBNR reserves for losses that have occurred but for which claims have not yet been reported which include a provision for expected future development on case reserves. These reserves are estimates based on actuarial, claims and underwriting assessments of what we believe the settlement and administration of claims will cost based on facts and circumstances then known to us. Because of the uncertainties that surround estimating ultimate loss and LAE reserves, we cannot be certain that our reserves are adequate and actual claims and claim expenses paid might exceed our reserves due to the uncertainties that surround estimating loss and LAE reserves. If we determine in the future that our reserves are insufficient to cover our actual losses and LAE, we would have to add to our reserves, which could have a material adverse effect on our results of operations and financial condition.  For further discussion of our loss and LAE reserves, including our asbestos and environmental reserves, see “CRITICAL ACCOUNTING ESTIMATES - Loss and LAE Reserves” on page 74.

We may not be able to successfully alleviate risk through reinsurance and retrocessional arrangements. Additionally, we may not be able to collect all amounts due from our reinsurers under our existing reinsurance and retrocessional arrangements.
We attempt to limit our risk of loss through reinsurance and retrocessional arrangements. Retrocessional arrangements refer to reinsurance purchased by a reinsurer to cover its own risks assumed from ceding companies. The availability and cost of reinsurance and retrocessional protection is subject to market conditions, which are outside of our control. In addition, the coverage under our reinsurance and retrocessional arrangements may be inadequate to cover our future liabilities. As a result, we may not be able to successfully alleviate risk through these arrangements, which could have a material adverse effect on our results of operations and financial condition.
We are not relieved of our obligations to our policyholders or ceding companies by purchasing reinsurance. Accordingly, we are subject to credit risk with respect to our reinsurance and retrocessions in the event that a reinsurer is unable to pay amounts owed to us as a result of a deterioration in its financial condition. A number of reinsurers in the industry experienced such a deterioration in the aftermath of the 2001 terrorist attacks and the active 2005 hurricane season. To mitigate this risk, we annually review and periodically monitor our reinsurers’ financial condition. While we believe that our reinsurers’ financial condition is strong, it is possible that one or more of our reinsurers will be significantly adversely affected by future significant loss events, causing them to be unable to pay amounts owed to us. We also may be unable to recover amounts due under our reinsurance and retrocessional arrangements if our reinsurers choose to withhold payment due to a dispute or other factors beyond our control.

Brokers, agents or policyholders may react negatively to the Runoff Transaction.
Following OneBeacon's announcement of the Runoff Transaction, A.M. Best, Fitch, Moody's and Standard & Poor's each issued a press release regarding the ratings implications. A.M. Best placed the Runoff Subsidiaries under review with negative implications; Fitch placed the Runoff Subsidiaries on credit watch negative; and Moody's assigned a negative outlook. Standard & Poor's downgraded and subsequently, at the request of OneBeacon, withdrew its rating on the Runoff Subsidiaries. All four rating agencies affirmed the ratings on the Ongoing Subsidiaries with stable outlook.
The Runoff Subsidiaries have been underwriting specialty policies that have been ceded to the Ongoing Subsidiaries, and they will continue to do so on a limited basis up until the closing of the Runoff Transaction and for a limited time following the closing through a fronting and reinsurance agreement with Armour. It is possible that certain brokers, agents or policyholders dealing with specialty policies underwritten by the Runoff Subsidiaries could determine that the Runoff Subsidiaries no longer meet their placement standards and could cease placing business with the Runoff Subsidiaries. While OneBeacon believes that the Runoff Subsidiaries' financial strength is robust notwithstanding the Runoff Transaction, it intends to take various steps to provide assurances to the Runoff Subsidiaries’ brokers, agents and policyholders. However, there is no assurance that the Runoff Subsidiaries will be successful in continuing to underwrite the specialty business on an interim basis, which may have an adverse impact on OneBeacon.

Our reinsurance operations are largely dependent upon ceding companies’ evaluation of risk.
Sirius Group, like other reinsurance companies that write treaty reinsurance, generally does not evaluate separately each of the assumed individual insurance risks under our reinsurance contracts. As such, we are largely dependent upon the cedents’ original underwriting decisions. We are subject to the risk that the cedents may not have adequately or accurately evaluated the risks that they have insured, and we have reinsured, and that the premiums ceded may not adequately compensate us for the risks we assume. If our reserves are insufficient to cover our actual loss and LAE arising from our treaty reinsurance business, we would have to strengthen our reserves and incur charges to our earnings. These charges could be significant and could have a material adverse effect on our results of operations and financial condition.

We have significant foreign operations that expose us to certain additional risks, including foreign currency risks and political risk.
Sirius Group conducts a significant portion of its business outside of the United States. As a result, a significant portion of our assets, liabilities, revenues and expenses are denominated in currencies other than the U.S. dollar and are therefore subject to foreign currency risk. Our foreign currency risk cannot be eliminated entirely and significant changes in foreign exchange rates may adversely affect our results of operations and financial condition.
Our foreign operations are also subject to legal, political and operational risks that may be greater than those present in the United States. As a result, our operations at these foreign locations could be temporarily or permanently disrupted.

Our debt, preferred stock and related service obligations could adversely affect our business.
As of December 31, 2012, we had approximately $752 million face value of indebtedness and $250 million face value of non-cumulative perpetual preference shares outstanding.

36


Our ability to meet our debt, preferred stock and related service obligations will depend on our future performance, which will be affected by financial, business, economic, regulatory and other factors, many of which are beyond our control.  We are also subject to restrictive financial covenants contained in our revolving credit facility that require us to maintain specified financial ratios and to satisfy financial condition tests.  These covenants can restrict us in several ways, including our ability to incur additional indebtedness.  A breach of these covenants could result in an event of default under our revolving credit facility which would allow lenders to declare any amounts owed under the revolving credit facility to be immediately due and payable.  A failure by certain of our subsidiaries to pay principal and interest on a credit facility, mortgage or similar debt agreement (“covered debt”), where such a default results in the acceleration of at least $75 million principal amount of covered debt, could trigger a cross acceleration provision contained in our revolving credit facility.  A failure by OneBeacon Ltd. subsidiaries to pay principal and interest on covered debt, where such failure results in the acceleration of at least $75 million principal amount of covered debt, could trigger the acceleration of the 2012 OBH Senior Notes. A failure by SIG subsidiaries to pay principal and interest on covered debt, where such failure results in the acceleration of at least $25 million principal amount of covered debt, could trigger the acceleration of the SIG Senior Notes. If we do not have enough cash to repay accelerated debt, we may be required to refinance all or part of our existing debt, sell assets, borrow more cash or sell equity.  We cannot assure you that we will be able to accomplish any of these alternatives on terms acceptable to us, if at all.
We could incur additional indebtedness and issue additional preferred stock in the future. To the extent new debt, new preferred stock and other obligations are added to our and our subsidiaries’ current debt and preferred stock levels, the risks described in the previous paragraph would increase.

We are a holding company with no direct operations, and our insurance and reinsurance subsidiaries’ ability to pay dividends and other distributions to us is restricted by law.
As a holding company with no direct operations, we rely on net investment income and dividends, tax sharing payments and other permitted payments from our subsidiaries to pay our expenses. Our subsidiaries may not be able to generate cash flow sufficient to pay a dividend or distribute funds to us. In addition, under the insurance laws of the jurisdictions in which our insurance and reinsurance subsidiaries are domiciled, an insurer or reinsurer is restricted with respect to the timing or the amount of dividends it may pay without prior approval by regulatory authorities.
Our top tier regulated insurance and reinsurance operating subsidiaries have the ability to pay approximately $1.2 billion of dividends and group contributions to us without prior approval of regulatory authorities during 2013.  At December 31, 2012, the Company and its intermediate holding companies had $132 million of net unrestricted cash, short-term investments and fixed maturity investments and $618 million of common equity securities and other long-term investments outside of OneBeacon and Sirius Group and $300 million available to be drawn from its revolving credit facility.  In addition, at December 31, 2012, OneBeacon Ltd. and its intermediate holding companies had $272 million of net unrestricted cash, short-term investments and fixed maturity investments and $33 million of common equity securities and convertible fixed maturity investments outside of its regulated and unregulated insurance operating subsidiaries; Sirius Group and its intermediate holding companies had $72 million of net unrestricted cash, short-term investments and fixed maturity investments and $18 million of other long-term investments outside of its regulated and unregulated insurance and reinsurance operating subsidiaries. See “Dividend Capacity” on page 64. Management believes that our cash balances, cash flows from operations and cash flows from investments are adequate to meet expected cash requirements for the foreseeable future on both a holding company and operating subsidiary level. However, if our insurance and reinsurance subsidiaries cannot pay dividends in future periods or if we contribute additional funds to fulfill our obligations under our life reinsurance contracts, we may have difficulty servicing our debt, paying dividends on our common and preferred shares and meeting our holding company expenses. For additional information relating to insurance and reinsurance regulations governing our operations, see “Regulation” on page 26.

We may suffer losses from unfavorable outcomes from litigation and other legal proceedings.
In the ordinary course of business, we are subject to litigation and other legal proceedings as part of the claims process, the outcomes of which are uncertain. We maintain reserves for these legal proceedings as part of our loss and LAE reserves. We also maintain separate reserves for legal proceedings that are not related to the claims process.  Additionally, we have agreed to indemnify Allstate in respect of certain litigation and other matters arising out of the operations of Esurance prior to the closing of the Esurance Sale.  In the event of an unfavorable outcome in one or more legal matters, our ultimate liability may be in excess of amounts we have currently reserved for and such additional amounts may be material to our results of operations and financial condition. For a description of our significant ongoing non-claims related legal proceedings, see “Legal Proceedings” on page 41 and Note 19 Commitments and Contingencies on page F-74.
As industry practices and legal, judicial, social and other conditions change, unexpected and unintended issues related to claims and coverage may emerge. These issues may adversely affect our results of operations and financial condition by either extending coverage beyond our underwriting intent or by increasing the number and size of claims. In some instances, these changes may not become apparent until sometime after we have issued insurance and reinsurance contracts that are affected by the changes.


37


Regulation may restrict our ability to operate.
The insurance and reinsurance industries are subject to extensive regulation under U.S., state and foreign laws. Governmental agencies have broad administrative power to regulate many aspects of the insurance business, which include premium rates, marketing practices, advertising, policy forms and capital adequacy. These governmental agencies are concerned primarily with the protection of policyholders rather than shareholders. Insurance laws and regulations impose restrictions on the amount and type of investments, prescribe solvency standards that must be met and maintained and require the maintenance of reserves. In our insurance underwriting, we rely heavily upon information gathered from third parties such as credit report agencies and other data aggregators. The use of this information is also highly regulated and any changes to the current regulatory structure could materially affect how we underwrite and price premiums.
Changes in laws and regulations may restrict our ability to operate and/or have an adverse effect upon the profitability of our business within a given jurisdiction. In addition, state and federal legislation has been proposed to establish catastrophe funds and underwriting in coastal areas which could impact our business.
In addition, the Dodd-Frank Act, which was enacted in 2010, created the FIO within the Treasury Department. The FIO is responsible for gathering information and monitoring the insurance industry to identify gaps in the regulation of insurers that could contribute to a systemic crisis in the insurance industry or U.S. financial system. The FIO also has the authority to recommend changes to state insurance laws and regulations. We cannot predict whether the FIO will recommend any such changes, whether any states will adopt any such changes, or what effect such changes may have on our insurance operations.
Our non-U.S. reinsurance companies are subject to foreign regulations, including Solvency II which regulates insurance firms that operate in the EU.  A definitive effective date for Solvency II regulation has not yet been established, but implementation could occur in the next few years. Solvency II was enacted to reduce the risk that insurers would not be able to pay claims to policyholders as well as promote financial stability through minimum capital requirements as well as other requirements for the governance and risk management of insurers and the supervision of insurers.  We cannot predict what regulations will be adopted to implement Solvency II nor the impact of such regulation upon our non-U.S. reinsurers or their wholly owned subsidiaries.  In addition, it is possible that the NAIC could adopt part or all of Solvency II including minimum capital requirements that could be in excess of our current minimum capital requirements established by state regulations.  If the NAIC adopted Solvency II including additional capital requirements, our business and results of operations could be materially impacted.

We could be subject to litigation, regulatory enforcement action and damage to our reputation if confidential personally identifiable information is mishandled or stolen.
Our operating entities collect and store personally identifiable information from consumers.  If our data security measures fail and personally identifiable information is mishandled or stolen, we could be subject to litigation and regulatory enforcement action.  Further, such a failure could damage our reputation, which could have an adverse effect on our business, results of operations and financial condition.

Our profitability may be adversely impacted by inflation, legislative actions and judicial decisions.
The effects of inflation could cause claim costs to rise in the future. In addition, legislative actions and judicial decisions continue to broaden liability and policy definitions and to increase the severity of claim payments, such as described above with respect to asbestos and environmental claims. To the extent inflation and these legislative actions and judicial decisions cause claim costs to increase above reserves established for these claims, we will be required to increase our loss and LAE reserves with a corresponding reduction in our net income in the period in which the deficiency is identified.

We have successfully created shareholder value through acquisitions and dispositions of insurance and reinsurance entities. We may not be able to continue to create shareholder value through such transactions in the future.
In past years, we have completed numerous acquisitions and dispositions of insurance and reinsurance entities, many of which have contributed significantly to our growth in adjusted book value. Failure to identify and complete future acquisition and disposition opportunities could limit our ability to achieve our target returns. Even if we were to identify and complete future acquisition or disposition opportunities, there is no assurance that such opportunities will ultimately achieve their anticipated benefits.


38


We have significant deferred tax assets which we may be unable to utilize if we do not generate sufficient future taxable income.
We have a deferred tax asset of $146 million (net of a valuation allowance of $36 million) related to net operating loss carryforwards, capital loss carryforwards and tax credit carryforwards at December 31, 2012 that are subject to carryforward limitations in the United States.  We also have a deferred tax asset of $317 million (net of a valuation allowance of $192 million) related to net operating loss carryforwards in Luxembourg at December 31, 2012 that are not subject to limitation. The loss carryforwards in Luxembourg primarily relate to tax deductible write-downs in 2007 and 2008 of investments in U.S. subsidiaries held by Luxembourg subsidiaries. Utilization of these assets and other assets included in our worldwide net deferred tax asset of $228 million (net of a valuation allowance of $254 million) is dependent on generating sufficient future taxable income of the appropriate character (i.e. ordinary income or capital gains) in the appropriate jurisdiction. If it is determined that it is more likely than not that sufficient future taxable income will not be generated, we would be required to increase the valuation allowance in future periods, which would have an adverse effect on our results of operations and financial condition.

Changes in tax laws or tax treaties may cause more of the income of certain non-U.S. companies in our group to become subject to taxes in the United States.
The taxable income of our U.S. subsidiaries is subject to U.S. federal, state and local income tax and other taxes. The income of the non-U.S. companies in our group is generally subject to a lower effective tax rate than that imposed by the United States. Certain of our non-U.S. companies are eligible for the benefits of tax treaties between the United States and other countries. We believe our non-U.S. companies will continue to be eligible for treaty benefits. However, it is possible that factual changes or changes to U.S. tax laws or changes to tax treaties that presently apply to our non-U.S. companies could increase income subject to tax, or the tax rate on income, in the United States.  For example, legislation has been introduced into Congress that would tax a corporation based on the domicile of its officers rather than the domicile of the corporation.  Similarly, changes to the applicable tax laws, treaties or regulations of other countries could subject the income of members of our group to higher rates of tax outside the United States.

We have significant deferred tax assets which we may be unable to utilize pursuant to the newly enacted Swedish tax legislation.
On January 1, 2013, new tax legislation became effective in Sweden that limits the deductibility of interest paid on certain intra-group debt instruments. Uncertainty exists with respect to the interpretation of the legislation. Adverse interpretation of the legislation could cause us to write down some or all of the $55 million in deferred tax assets related to intra-group debt instruments in our internal capital structure, which would have an adverse effect on our results of operations and financial condition.

We depend on our key personnel to manage our business effectively and they may be difficult to replace.
Our performance substantially depends on the efforts and abilities of our management team and other executive officers and key employees. Furthermore, much of our competitive advantage is based on the expertise, experience and know-how of our key management personnel. We do not have fixed term employment agreements with any of our key employees nor key man life insurance and the loss of one or more of these key employees could adversely affect our business, results of operations and financial condition. Our success also depends on the ability to hire and retain additional personnel. Difficulty in hiring or retaining personnel could adversely affect our results of operations and financial condition.

Bermuda law differs from the laws in effect in the United States and may afford less protection to shareholders.
We are organized under the laws of Bermuda, and a portion of our assets are located outside the United States. As a result, it may not be possible for our shareholders to enforce court judgments obtained in the United States against us based on the civil liability provisions of the federal or state securities laws of the United States, either in Bermuda or in countries other than the United States where we will have assets. In addition, there is some doubt as to whether the courts of Bermuda and other countries would recognize or enforce judgments of U.S. courts obtained against us or our directors or officers based on the civil liabilities provisions of the federal or state securities laws of the United States or would hear actions against us or those persons based on those laws.

Our corporate affairs are governed by the Companies Act. The Companies Act differs in some material respects from laws generally applicable to U.S. corporations and shareholders, including the provisions relating to interested directors, amalgamations, mergers and acquisitions, takeovers, shareholder lawsuits and indemnification of directors. Generally, the duties of directors and officers of a Bermuda company are owed to the company only. Shareholders of Bermuda companies generally do not have rights to take action against directors or officers of the company and may only do so in limited circumstances. Class actions and derivative actions are generally not available to shareholders under Bermuda law. The Bermuda courts, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong to the company where the act complained of is alleged to be beyond the corporate power of the company or illegal, or would result in the violation of the company’s memorandum of association or bye-laws. Furthermore, consideration would be given by a Bermuda court to acts that are alleged to constitute a fraud against non-controlling shareholders or, for instance, where an act requires the approval of a greater percentage of the company’s shareholders than that which actually approved it.
When the affairs of a company are being conducted in a manner that is oppressive or prejudicial to the interests of some part of the shareholders, one or more shareholders may apply to the Supreme Court of Bermuda, which may make such order as it sees fit, including an order regulating the conduct of the company’s affairs in the future or ordering the purchase of the shares of any shareholders by other shareholders or by the company. Additionally, under our bye-laws and as permitted by Bermuda law, each shareholder has waived any claim or right of action against our directors or officers for any action taken by directors or officers in the performance of their duties, except for actions involving fraud or dishonesty. In addition, the rights of our shareholders and the fiduciary responsibilities of our directors under Bermuda law are not as clearly established as under statutes or judicial precedent in existence in jurisdictions in the United States, particularly the State of Delaware. Therefore, our shareholders may have more difficulty protecting their interests than would shareholders of a corporation incorporated in a jurisdiction within the United States.

Item 3.  Legal Proceedings
White Mountains, and the insurance and reinsurance industry in general, is subject to litigation and arbitration in the normal course of business. Other than those items listed below, White Mountains was not a party to any material litigation or arbitration other than as routinely encountered in claims activity, none of which is expected by management to have a material adverse effect on its financial condition and/or cash flows.

Esurance Sale
In 2011, the Company sold its Esurance and Answer Financial businesses (the "Transferred Companies") to The Allstate Corporation (“Allstate”) for a purchase price of approximately $1.01 billion. The purchase price consisted of $700 million plus the tangible book value of the Transferred Companies at the closing, which was estimated to be $308 million. Following closing, Allstate was required to prepare a final closing statement, including an audited balance sheet for the Transferred Companies as of the closing date.  The Company is disputing Allstate's calculation of tangible book value in the closing statement.  The amount in dispute is approximately $20 million.  The dispute principally relates to (i) the elimination of $25 million (pre-tax) of deferred acquisition costs ($16 million, after tax) and (ii) the inclusion of a liability equal to the costs associated with an Esurance extra-contractual (“ECO”) matter settled in April 2012 of $5 million ($3 million, after tax). Per the agreement governing the sale of the Transferred Companies (the “Sale Agreement”), disputes over the closing statement are to be arbitrated by an independent accountant.
The Company believes this final closing statement was required to be prepared and audited no later than January 5, 2012.  Allstate did not deliver the final closing statement to the Company until June 6, 2012, with an audit report dated June 1, 2012. As a result, in addition to the substantive disputes over the final closing statement, the Company also believes that Allstate's failure to have the final closing statement prepared and audited by the required date constituted a breach of Allstate's obligations under the Sale Agreement. The Company brought suit in the United States District Court for the Southern District of New York in connection with such breach. The court concluded that the Company’s breach claim should also be arbitrated by the independent accountant under the Sale Agreement. That process is proceeding.

Tribune Company
In June 2011, Deutsche Bank Trust Company Americas, Law Debenture Company of New York and Wilmington Trust Company (collectively referred to as “Plaintiffs”), in their capacity as trustees for certain senior notes issued by the Tribune Company (“Tribune”), filed lawsuits in various jurisdictions (the “Noteholder Actions”) against numerous defendants including OneBeacon, OBIC-sponsored benefit plans and other affiliates of White Mountains in their capacity as former shareholders of Tribune seeking recovery of the proceeds from the sale of common stock of Tribune in connection with Tribune's leveraged buyout in 2007 (the “LBO”). Tribune filed for bankruptcy in 2008 in the Delaware bankruptcy court (the “Bankruptcy Court”) and emerged from bankruptcy at the end of 2012 in a Chapter 11 reorganization. During the bankruptcy proceedings, the Bankruptcy Court granted Plaintiffs permission to commence these LBO-related actions. Plaintiffs seek recovery of the proceeds received by the former Tribune shareholders on a theory of constructive fraudulent transfer asserting that Tribune purchased or repurchased its common shares without receiving fair consideration at a time when it was, or as a result of the purchases of shares, was rendered, insolvent. OneBeacon has entered into a joint defense agreement with other affiliates of White Mountains that are defendants in the action. Certain subsidiaries of White Mountains received a total of approximately $39 million for Tribune common stock tendered in connection with the LBO.
        In December 2011, the Judicial Panel on Multidistrict Litigation granted a motion to consolidate all of the Noteholder Actions for pretrial matters and transfer all such proceedings to the United States District Court for the Southern District of New York.
        In addition, OneBeacon, OBIC-sponsored benefit plans and other affiliates of White Mountains in their capacity as former shareholders of Tribune, along with thousands of former Tribune shareholders, have been named as defendants in an adversary proceeding brought by the Official Committee of Unsecured Creditors of the Tribune Company, on behalf of the Tribune Company, which seeks to avoid the repurchase of shares by Tribune in the LBO on a theory of intentional fraudulent transfer (the “Committee Action”). The Committee Action has been consolidated with the Noteholder Actions.
In September 2012, a case management order was entered in the consolidated cases, setting forth, among other things, a briefing schedule for an omnibus motion to dismiss in the Noteholder Actions. The court is expected to hear oral argument on that motion in March 2013. Discovery and other motion practice (other than motions to amend the complaints) in the Committee Action and the Noteholder Actions is stayed until further order of the court.

 Ace American Insurance Company
A subsidiary of OneBeacon, OBH, was sued in Federal Court in the Eastern District of Pennsylvania on August 17, 2012 by Ace American Insurance Company (“Ace”).  The complaint alleges that OBH, through a professional recruiting firm, improperly hired a group of Ace employees from Ace's surety division.  The complaint sought injunctive relief and unspecified damages. After court-ordered expedited discovery was completed, the claims for injunctive relief were resolved pursuant to a confidential agreement.  The remaining claim against OBH is for damages only and is scheduled to be heard in April.  After the claims against OBH for injunctive relief were resolved, Ace filed a Demand for Arbitration against five of the former Ace surety employees hired by OneBeacon, alleging breach of their duty of loyalty to Ace and misappropriation of Ace trade secrets.  OneBeacon believes that Ace's damages claim against OBH and the claims against the individual employees are without merit and intends to vigorously defend both.

(a) 
Due to the global financial crisis, during 2008 White Mountains experienced significant decreases in: realized and unrealized investment returns reported in revenues; net income; total assets; and adjusted book value per share.
(b) 
As a result of the Esurance Sale, the AutoOne Sale, and the Runoff Transaction, White Mountains has reclassified the results from these businesses for the past five years in the table above to discontinued operations, net of tax. In 2012, discontinued operations, net of tax, includes a $91 loss related to the sale of the Runoff Business and a net loss of $24 related to the operations of the Runoff Business. In 2011, discontinued operations, net of tax, includes a $678 gain related to the Esurance Sale, a $19 loss related to the AutoOne Sale, and a $37 net loss related to the Runoff Business.
(c) 
At December 31, 2012, White Mountains had $75 outstanding under its credit facility, which was repaid in January 2013. During 2011 and 2010, OneBeacon repurchased $150 and $187 face value of the OBH Senior Notes. At December 31, 2008, White Mountains had $200 outstanding under its credit facility, which was repaid during 2009.
(d) 
During 2012, White Mountains capitalized HG Global with approximately $600 to fund the start-up of BAM. At December 31, 2012, White Mountains owned 97.3% of HG Global’s preferred equity and 88.7% of its common equity. White Mountains does not have an ownership interest in BAM, which is a mutual insurance company owned by its members. Accordingly, all of BAM’s results are attributed to non-controlling interest.
(e) 
Includes the dilutive effects of outstanding incentive options to acquire common shares. Non-qualified options were not included in the diluted earnings per share denominator as their inclusion would be anti-dilutive for the periods presented.
(f) 
Adjusted book value per share is a non-GAAP measure which is derived by expanding the GAAP book value per share calculation to include the effects of assumed conversion of all in-the-money convertible securities and to exclude the net unrealized gains (losses) from Symetra’s fixed maturity portfolio and unearned restricted common shares. See the reconciliation of adjusted book value per share to book value per share on page 47.
(g) 
During 2012, 2011 and 2010, White Mountains repurchased 1,329,640, 646,502 and 687,871, respectively, of its common shares through a combination of tender offers, open market transactions and other transactions.
(h) 
Includes outstanding options to acquire common shares, when applicable, and excludes unearned shares of restricted stock, the compensation of which, at the date of calculation, has yet to be amortized.

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion contains “forward-looking statements”. White Mountains intends statements that are not historical in nature, which are hereby identified as forward-looking statements, to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. White Mountains cannot promise that its expectations in such forward-looking statements will turn out to be correct. White Mountains’ actual results could be materially different from and worse than its expectations. See “FORWARD-LOOKING STATEMENTS” on page 102 for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.
The following discussion also includes three non-GAAP financial measures, adjusted comprehensive income, adjusted book value per share and adjusted capital, that have been reconciled to their most comparable GAAP financial measures (see page 73). White Mountains believes these measures to be more relevant than comparable GAAP measures in evaluating White Mountains’ financial performance and condition.

White Mountains ended 2012 with an adjusted book value per share of $588, an increase of 8.6%, including dividends, from December 31, 2011. White Mountains reported adjusted comprehensive income of $245 million in 2012 compared to adjusted comprehensive income of $745 million in 2011, which included an after-tax gain of $678 million from the Esurance Sale.
OneBeacon's book value per share decreased 0.8% during 2012, including dividends. OneBeacon's 2012 results included $101 million of after-tax GAAP losses related to the sale of its Runoff Business, which resulted in a decrease of $12 to White Mountains’ adjusted book value per share (net of non-controlling interest). OneBeacon's GAAP combined ratio was 98% for 2012 compared to 92% for 2011. The increase was primarily driven by higher catastrophe losses, mainly from hurricane Sandy, lower favorable loss reserve development and higher expenses. Sirius Group's GAAP combined ratio was 90% for 2012 compared to 100% for 2011. Sirius Group’s combined ratio for 2012 included 13 points of catastrophe losses, 11 points of which were from hurricane Sandy, compared to 24 points of catastrophe losses for 2011. Additionally, Sirius Group’s combined ratio for 2012 included 3 points of losses from its agricultural line of business, primarily as a result of the drought in the midwestern United States.
Total net written premiums increased 8% to $2,127 million in 2012 from $1,978 million in 2011, due to higher net written premiums at both OneBeacon and Sirius Group.  OneBeacon’s net written premiums increased 11% to $1,179 million in 2012, primarily due to new business and improved retention in several lines, particularly within the accident, government risk, energy and technology businesses. In January 2013, OneBeacon terminated its relationship with Hagerty and sold Essentia, the wholly owned subsidiary that wrote OneBeacon’s Hagerty collector car and boat business, to Markel Corporation. Business written through Hagerty generated net written premiums of approximately 8% of White Mountains’ consolidated net written premiums in each of 2012, 2011 and 2010. OneBeacon will recognize a $23 million pre-tax gain on the sale of Essentia ($15 million after tax) in the first quarter of 2013. Sirius Group’s net written premiums increased 3% to $948 million in 2012, primarily due to increases in the accident and health and property lines of business, partially offset by a decrease in the trade credit line of business.
White Mountains’ GAAP investment return was 4.9% in 2012. The fixed income portfolio return (in local currencies) of 3.8% was higher than the Barclay’s Intermediate Aggregate Bond Index return of 3.6%, despite significantly less duration risk, while the equity portfolio return was 7.7% compared to the S&P 500 Index return of 16.0%. In addition, adjusted book value per share increased $10 in 2012 from share repurchases and $3 from foreign currency translation.
Effective January 1, 2013, Sweden reduced its corporate tax rate from 26.3% to 22.0%, and Luxembourg increased its corporate tax rate from 28.8% to 29.2%.  This resulted in a reduction in Sirius Group's net deferred tax liabilities in Sweden and an increase in Sirius Group's net deferred tax assets in Luxembourg at December 31, 2012. In addition, during the quarter Sirius Group had a net release of valuation allowances on deferred tax assets in Luxembourg and White Mountains established a valuation allowance on deferred tax assets of a group of U.S. companies reported in the Other Operations segment. In total, these changes resulted in an increase to adjusted book value per share of $13 in the fourth quarter of 2012.

Overview-Year Ended December 31, 2011 versus Year Ended December 31, 2010
White Mountains ended 2011 with an adjusted book value per share of $542, an increase of 23%, including dividends, from December 31, 2010. White Mountains reported adjusted comprehensive income of $745 million in 2011 compared to adjusted comprehensive income of $141 million in 2010. The increase in adjusted book value per share in 2011 was driven by an $89 increase from the gain from the Esurance Sale, net of transaction related expenses.
OneBeacon’s book value per share increased 3% during 2011, including dividends. OneBeacon's GAAP combined ratio was 92% for 2011 compared to 96% for 2010. The decrease was primarily driven by improved current accident year results, partially offset by higher catastrophe losses. Sirius Group’s GAAP combined ratio was 100% for 2011 compared to 94% for 2010. Both years were impacted by significant catastrophe losses as 2011 included 24 points of catastrophe losses compared to 23 points in 2010.
Total net written premiums decreased 3% to $1,978 million in 2011 from $2,034 million in 2010. Excluding the $180 million of net written premiums in 2010 related to OneBeacon’s personal lines business, net written premiums were up 7% in 2011, due to higher net written premiums at both OneBeacon and Sirius Group. OneBeacon's net written premiums increased 8% to $1,063 million in 2011, primarily due to new business and improved retention in several lines, particularly within the accident, government risk, energy and technology businesses. Sirius Group's net written premiums increased 6% to $916 million in 2011, primarily due to increases in the accident and health and trade credit lines of business and foreign currency translation.
White Mountains’ GAAP investment return was 2.9% in 2011. The fixed income portfolio return (in local currencies) of 3.1% was lower than the Barclay’s Intermediate Aggregate Bond Index return of 6.0%, as the fixed income portfolio trailed the longer-duration benchmark as rates declined. The equity portfolio return was 1.4% compared to the S&P 500 Index return of 2.1%.
In addition, adjusted book value per share increased $17 in 2011 from the release of a valuation allowance against deferred tax assets in two Luxembourg subsidiaries and $5 from share repurchases. Also, adjusted book value per share decreased $6 in 2011 from a GAAP other-than-temporary impairment write-down on the investment in Symetra common shares. White Mountains concluded that the accounting impairment on its investment in Symetra common shares existed due to the prolonged low interest rate environment in which life insurance companies operate and not from reasons specific to Symetra itself. As a result, White Mountains does not believe that the accounting impairment equates to an impairment in Symetra's long-term intrinsic business value. See CRITICAL ACCOUNTING ESTIMATES - White Mountains’ Investment in Symetra Common Shares on page 100 for a more detailed discussion.  Foreign currency translation did not have a significant impact on adjusted book value per share in 2011.

Consolidated Results—Year Ended December 31, 2012 versus Year Ended December 31, 2011
White Mountains’ total revenues increased 12% to $2,436 million in 2012 compared to $2,173 million in 2011, primarily due to higher earned insurance and reinsurance premiums, foreign currency translation gains, higher net realized and unrealized investment gains and an improvement of the mark-to-market performance of the Symetra warrants, partially offset by lower net investment income. Earned premiums increased 7% to $2,064 million in 2012, with an 11% increase at OneBeacon and a 3% increase at Sirius Group. Net investment income was down 17% to $154 million in 2012, principally due to a lower invested asset base driven by share repurchases and lower fixed maturity yields. White Mountains reported net realized and unrealized investment gains of $118 million in 2012 compared to $74 million in 2011. Net realized and unrealized investment gains for both periods were impacted by foreign currency translation on U.S. dollar-denominated investments at Sirius International, the effects of which are offset in other comprehensive income (see “Impact of Foreign Currency on Investment Returns” on page 59). Other revenues increased to a gain of $100 million in 2012 from a loss of $10 million in 2011, due primarily to $40 million in foreign currency translation gains and $18 million in mark-to-market gains on the Symetra warrants in 2012, compared to $6 million in foreign currency translation losses and $25 million in mark-to-market losses on the Symetra warrants in 2011.  Other revenues included a $25 million loss from WM Life Re in 2012 compared to a $16 million loss in 2011. See Note 8 - Variable Annuity Reinsurance for details regarding WM Life Re’s total impact on White Mountains’ statement of operations. Other revenues in 2012 also included a $15 million pre-tax gain on Sirius Group’s sale of IMG, $14 million in pre-tax transaction gains from White Mountains Solutions’ acquisitions that closed in 2012, a $5 million pre-tax gain on OneBeacon’s sale of a shell company and a $6 million pre-tax loss from OneBeacon’s repurchase of its remaining 2003 OBH Senior Notes. Other revenues in 2011 included a $7 million pre-tax gain from Sirius Group’s acquisition of Old Lyme.
White Mountains’ total expenses increased 5% to $2,173 million in 2012 compared to $2,075 million in 2011. Losses and LAE expenses increased 2% and insurance and reinsurance acquisition expenses increased by 7%, driven by increased business volume. The increase in loss and LAE expenses was partially offset by lower catastrophe losses. Other underwriting expenses increased 20%, driven by increased business volume, start-up costs for new specialty businesses at OneBeacon and the migration of OneBeacon’s corporate functions to Minnesota. General and administrative expenses were $172 million in 2012, which includes $20 million in expenses from the consolidation of BAM, compared to $167 million in 2011. Excluding the $20 million of expenses related to BAM, general and administrative expenses decreased 9% in 2012, primarily due to lower incentive compensation expenses. 2011 included a higher level of incentive compensation expenses as a result of the gain from the Esurance Sale and a 35% increase in White Mountains’ stock price during 2011 compared to a 14% increase in 2012. Interest expense on debt decreased 19% to $45 million in 2012 compared to $55 million in 2011, primarily due to reductions of outstanding debt resulting from repurchases of the 2003 OBH Senior Notes.

Consolidated Results—Year Ended December 31, 2011 versus Year Ended December 31, 2010
White Mountains’ total revenues decreased 7% to $2,173 million in 2011 compared to $2,334 million in 2010, primarily due to lower earned insurance premiums, net investment income, net investment gains and other revenues. Earned premiums were down 5% to $1,925 million in 2011, due primarily to a 14% decrease at OneBeacon, which was driven by the sale of its personal lines business in 2010. Excluding the $202 million of earned premiums in 2010 related to OneBeacon’s personal lines business, earned premiums were up 5% in 2011, with a 3% increase at OneBeacon and an 8% increase at Sirius Group. Net investment income was down 12% to $185 million in 2011, due primarily to lower fixed maturity yields and a reduction in invested assets from the sale of OneBeacon’s personal lines business in 2010, repurchases of a portion of the 2003 OBH Senior Notes and share repurchases. White Mountains reported net realized and unrealized investment gains of $74 million in 2011 compared to $78 million in 2010. Net realized and unrealized investment gains for both periods were significantly impacted by foreign currency translation on U.S. dollar-denominated investments at Sirius International, the effects of which are offset in other comprehensive income (see “Impact of Foreign Currency on Investment Returns” on page 59). Other revenues decreased to a loss of $10 million in 2011 from a gain of $18 million in 2010, due primarily to foreign currency translation losses and higher mark-to-market losses on the Symetra warrants, partially offset by lower losses reported by WM Life Re.  Other revenues included a $16 million loss from WM Life Re in 2011 compared to a $45 million loss in 2010.  Other revenues in 2011 also included a $7 million pre-tax gain from Sirius Group’s acquisition of Old Lyme, while other revenues in 2010 included a $13 million pre-tax gain from Sirius Group’s acquisition of Central National.
White Mountains’ total expenses decreased 3% to $2,075 million in 2011 compared to $2,144 million in 2010. Excluding the $218 million of expenses reported in 2010 related to OneBeacon’s personal lines business, White Mountains’ total expenses increased 8% in 2011, as losses and LAE expenses, insurance and reinsurance acquisition expenses and other underwriting expenses increased 10%, 6% and 2%, driven by increased business volume. The increase in loss and LAE expenses was also due to higher catastrophe losses. General and administrative expenses increased 14% to $167 million in 2011 compared to $147 million in 2010, due primarily to increased compensation expenses as a result of the gain from the Esurance Sale and to the 35% increase in White Mountains’ stock price during 2011.  Interest expense on debt decreased 4% to $55 million in 2011 compared to $57 million in 2010, primarily due to reductions of outstanding debt resulting from repurchases of the 2003 OBH Senior Notes.

Income Taxes
The Company and its Bermuda-domiciled subsidiaries are not subject to Bermuda income tax under current Bermuda law.  In the event there is a change in the current law such that taxes are imposed, the Company and its Bermuda-domiciled subsidiaries would be exempt from such tax until March 31, 2035, pursuant to the Bermuda Exempted Undertakings Tax Protection Act of 1966. The Company has subsidiaries and branches that operate in various other jurisdictions around the world that are subject to tax in the jurisdictions in which they operate. The jurisdictions in which the Company’s subsidiaries and branches are subject to tax are Australia, Belgium, Canada, Germany, Gibraltar, Luxembourg, the Netherlands, Singapore, Sweden, Switzerland, the United Kingdom and the United States.
White Mountains reported an income tax benefit of $16 million in 2012 on pre-tax income of $263 million. Effective January 1, 2013, Sweden reduced its corporate tax rate from 26.3% to 22.0% and Luxembourg increased its corporate tax rate from 28.8% to 29.2%. This resulted in a reduction in deferred tax liabilities in Sweden and an increase in deferred tax assets in Luxembourg at December 31, 2012. As a result, Sirius Group recognized $73 million in tax benefits from these changes. In addition, during the quarter Sirius Group had a net release of valuation allowances on deferred tax assets in Luxembourg, resulting in a tax benefit of $41 million, and White Mountains established a valuation allowance on deferred tax assets of a group of U.S. companies reported in the Other Operations segment, resulting in a tax expense of $38 million. In total, White Mountains recognized $76 million in overall net tax benefits from these changes. Excluding the impact of these changes, White Mountains effective tax rate for 2012 was 23%, which was lower than the U.S. statutory rate of 35% due primarily to income generated in jurisdictions other than the United States.
White Mountains reported an income tax benefit of $110 million in 2011 on pre-tax income of $98 million, due primarily to a $130 million tax benefit from the release of a valuation allowance against certain deferred tax assets as a result of the reorganization of Sirius Group. In connection with the reorganization, which included Sirius Group’s acquisition of a Luxembourg holding company from OneBeacon in January 2012, internal debt was contributed to holding companies that had large deferred tax assets offset by full valuation allowances.  Because the reorganization created a future stream of income for these holding companies, White Mountains was required to reduce the valuation allowances by $130 million in the fourth quarter of 2011. White Mountains also recorded a reclassification of $3 million of equity from White Mountains’ common shareholders’ equity to non-controlling interest, which represents OneBeacon’s minority shareholders’ portion of the excess of the purchase price over the net assets of the Luxembourg holding company.  Excluding the valuation allowance reduction, White Mountains effective tax rate for 2011 was 20%, which was lower than the U.S. statutory rate of 35% due primarily to income generated in jurisdictions other than the United States. 
The income tax expense related to pre-tax income for 2010 represented an effective tax rate of 16.0%, which was lower than the U.S. statutory rate of 35% due primarily to income generated in jurisdictions other than the United States.

Discontinued Operations
On October 17, 2012, OneBeacon entered into an agreement to sell its runoff business to Armour and recorded $101 million in after-tax losses related to the Runoff Transaction in 2012. These losses are composed of a $92 million after-tax loss on sale and a $9 million after-tax loss related to a reduction in the workers compensation loss reserve discount rate on reserves being transferred as part of the sale. The transaction is expected to close in the second half of 2013. On October 7, 2011, White Mountains completed the sale of Esurance to Allstate for cash equal to $700 million plus the tangible book value at closing of the entities being sold and recorded a gain of $678 million.  In 2011, OneBeacon agreed to sell its AutoOne business to Interboro and recorded a charge of $19 million after tax for the estimated loss on the sale. The AutoOne transaction closed in February 2012. 
As a result of these transactions, the results of the Runoff Business, the Esurance and AutoOne businesses and related transaction gains and losses are reported in discontinued operations in White Mountains’ GAAP financial statements.

I. Summary of Operations By Segment

White Mountains conducts its operations through four segments: (1) OneBeacon, (2) Sirius Group, (3) HG Global/BAM and (4) Other Operations. While investment results are included in these segments, because White Mountains manages the majority of its investments through its wholly-owned subsidiary, WM Advisors, a discussion of White Mountains’ consolidated investment operations is included after the discussion of operations by segment. White Mountains’ segment information is presented in Note 14 —“Segment Information” to the Consolidated Financial Statements.

OneBeacon Results—Year Ended December 31, 2012 versus Year Ended December 31, 2011
OneBeacon ended 2012 with a book value per share of $10.63, a decrease of 0.8%, including dividends (a quarterly dividend of $0.21 per share) from December 31, 2011. The decrease in book value was driven by a $92 million estimated after-tax loss on the Runoff Transaction and $24 million of net after-tax operating losses from discontinued operations, which included a $9 million after-tax charge related to the Runoff Transaction from a reduction in the workers compensation loss reserve discount rate. This negative impact to book value was partially offset by a $14 million increase from the sale of OneBeacon Holdings (Luxembourg) S.à r.l. to Sirius Group. The transaction was recorded as an increase in OneBeacon’s equity and was eliminated in White Mountains’ consolidated financial statements. OneBeacon’s GAAP return of investments was 4.4% for 2012.
OneBeacon’s GAAP combined ratio increased to 98% for 2012 from 92% for 2011, primarily driven by lower favorable loss reserve development, higher catastrophe losses and higher expenses. Favorable loss reserve development for 2012 was $7 million, or 1 point, compared to $30 million, or 3 points, for 2011. The favorable reserve development for 2012 was primarily in the workers' compensation, multiple peril liability and general liability lines, mostly offset by adverse loss reserve development on excess property claims. The combined ratio for 2012 included 5 points of net catastrophe losses ($56 million, including $8 million of ceded reinstatement premiums), due primarily to the impact of hurricane Sandy, compared to 4 points ($37 million) of catastrophe losses for 2011, primarily related to hurricane Irene, tornados in the southeastern and midwestern United States as well as storms and freezing weather in the northeastern and southwestern United States. The increase in the expense ratio is primarily the result of start up costs for new specialty businesses and costs associated with actions taken to migrate certain corporate functions to Minnesota in 2012.
OneBeacon’s net written premiums increased 11% in 2012 to $1,179 million, compared to $1,063 million in 2011, primarily due to the growth in several underwriting units, particularly within the Professional Insurance, Technology and Accident units. In January 2013, OneBeacon terminated its relationship with Hagerty and sold Essentia, the wholly owned subsidiary that wrote OneBeacon’s Hagerty collector car and boat business, to Markel Corporation. For the years ended December 31, 2012, 2011 and 2010, business written through Hagerty generated net written premiums of approximately 15%, 16% and 13%, respectively, of OneBeacon’s consolidated net written premiums. OneBeacon will recognize a $23 million pre-tax gain on the sale of Essentia ($15 million after tax) in the first quarter of 2013.
OneBeacon’s other revenues in 2012 included a $6 million loss related to the repurchase of its 2003 OBH Senior Notes, offset in part by a $5 million gain on the sale of a shell company, Pennsylvania General Insurance. OneBeacon’s other revenues in 2011 included a $12 million loss related to the partial redemption of a portion of the 2003 OBH Senior Notes.
OneBeacon’s losses and LAE expenses increased 19% and insurance and reinsurance acquisition expenses increased by 13%, driven by increased business volume. The increase in loss and LAE expenses was also partially due to higher catastrophe losses, driven by hurricane Sandy. Other underwriting expenses increased 26%, driven by increased business volume, start-up costs for new specialty businesses at OneBeacon and the migration of OneBeacon’s corporate functions to Minnesota. Interest expense decreased 18% to $17 million in 2012, reflecting lower outstanding debt.
Reinsurance protection. OneBeacon purchases reinsurance in order to minimize loss from large risks or catastrophic events. OneBeacon also purchases individual property reinsurance coverage for certain risks to reduce large loss volatility through property-per-risk excess of loss reinsurance programs and individual risk facultative reinsurance. OneBeacon also maintains excess of loss casualty reinsurance programs that provide protection for individual risk or catastrophe losses involving workers compensation, general liability, automobile liability, professional liability or umbrella liability. The availability and cost of reinsurance protection is subject to market conditions, which are outside of management’s control. Limiting risk of loss through reinsurance arrangements serves to mitigate the impact of large losses; however, the cost of this protection in an individual period may exceed the benefit.
OneBeacon’s net combined ratio for 2012 was lower than its gross combined ratio by 1 point, primarily due to the significant amount of reinsurance cessions related to hurricane Sandy, which were partially off-set by the impact of the cost of facultative reinsurance and property reinsurance, and also the cost of catastrophe reinsurance and marine reinsurance. OneBeacon’s net combined ratio for 2011 was higher than its gross combined ratio by 4 points, primarily due to the impact of the cost of facultative reinsurance and property reinsurance, and also the cost of catastrophe reinsurance and marine reinsurance.

OneBeacon Results—Year Ended December 31, 2011 versus Year Ended December 31, 2010
OneBeacon ended 2011 with a book value per share of $11.56, an increase of 3%, including dividends (quarterly dividends of $0.21 per share and a special dividend of $1.00 per share paid in June 2011) from December 31, 2010. OneBeacon’s GAAP investment return was 3.0% for 2011. OneBeacon’s results for 2011 were adversely impacted by a decline in the value of investment assets in OneBeacon’s pension plan, the loss resulting from a debt tender on the 2003 OBH Senior Notes, and the loss on the AutoOne sale.

52


OneBeacon’s GAAP combined ratio for 2011 decreased to 92% from 96% for 2010, primarily due to better current accident year results, partially offset by higher catastrophe losses. OneBeacon experienced a number of large losses in its property and inland marine business during 2010. The GAAP combined ratio for 2011 included 4 points of catastrophe losses compared to 2 points in 2010.  The GAAP combined ratio included 3 points of favorable loss reserve development for both years.
OneBeacon’s net written premiums decreased 8% in 2011 to $1,063 million from $1,168 million in 2010. Excluding $171 million of net written premiums in 2010 related to OneBeacon’s personal lines business, which was sold in July of 2010, OneBeacon’s net written premiums increased 8% in 2011, primarily due to new business and improved retention in several lines, particularly within the collector cars and boats, accident, government risk, energy and technology businesses.
OneBeacon's other revenues in 2011 included a $12 million loss related to the repurchase of a portion of the 2003 OBH Senior Notes. OneBeacon's other revenues in 2010 included a $9 million net gain on the sale of OneBeacon’s personal lines business, partially offset by an $11 million loss related to the repurchase of a portion of the 2003 OBH Senior Notes.
OneBeacon’s policy acquisition expenses decreased 12% to $221 million and other underwriting expenses decreased 17% to $162 million in 2011. Excluding the personal lines business that OneBeacon sold in 2010, OneBeacon’s policy acquisition expenses increased 4% and other underwriting expenses were essentially flat in 2011. Interest expense decreased 31% to $21 million in 2011, reflective of lower outstanding debt.
Reinsurance protection. OneBeacon’s net combined ratio for 2011 was higher than its gross combined ratio by 4 points, primarily due to the impact of the cost of facultative reinsurance and property reinsurance, and also the cost of catastrophe reinsurance and marine reinsurance. OneBeacon’s net combined ratio for 2010 was higher than its gross combined ratio by 4 points, primarily due to the impact of the cost of catastrophe reinsurance and facultative reinsurance.

Sirius Group Results—Year Ended December 31, 2012 versus Year Ended December 31, 2011
Sirius Group's GAAP combined ratio was 90% for 2012 compared to 100% for 2011. The decrease was primarily due to lower catastrophe losses, as the 2012 combined ratio included 13 points ($117 million) of catastrophe losses net of reinsurance and reinstatement premiums, primarily due to $98 million of losses from hurricane Sandy, compared to 24 points ($218 million) in 2011, primarily due to the Japan earthquake and tsunami, the New Zealand earthquakes and the floods in Thailand. Additionally, the 2012 combined ratio included 3 points of agricultural losses principally as a result of the drought in the midwestern United States. Favorable loss reserve development was 4 points for 2012. The major reductions in loss reserve estimates were recognized in casualty runoff ($32 million), property ($28 million), marine/energy ($12 million), trade credit ($7 million) and aviation/space ($5 million) lines, partially offset by a $46 million increase in asbestos and environmental loss reserves and a $4 million increase in accident and health. Favorable loss reserve development was 5 points for 2011 and was primarily attributable to $41 million of favorable development on property lines, partially offset by asbestos and environmental increases of $12 million.
Sirius Group's gross written premiums increased 4% (6% in local currencies) to $1,179 million in 2012 from $1,128 million for 2011, while net written premiums increased 3% (5% in local currencies) to $948 million for 2012 from $916 million in 2011.  These increases were primarily from the property and accident and health lines of business, partially offset by decreases in the casualty and trade credit lines.  Net written premiums for 2012 increased less than gross written premiums due to increased retrocessions on the property and accident and health lines of business. Net earned premiums increased 2% (4% in local currencies) to $932 million for 2012 from $912 million in 2011.
Sirius Group's other revenues primarily consisted of $40 million of foreign currency translation gains recorded in 2012 compared to foreign currency translation losses of $6 million in 2011. (See Impact of Foreign Currency on Investment Returns of on page 59.) Additionally, Sirius Group recorded pre-tax transaction gains of $14 million from White Mountains Solutions’ acquisitions of PICO, Citation, American General and American General Property and $15 million on the sale of its interest in an affiliate, IMG, a managing general underwriter in the medical and travel business. In 2011, Sirius Group recorded a $7 million pre-tax gain from White Mountains Solutions’ acquisition of the loss reserve portfolio of Old Lyme.
 Sirius Group's other underwriting expenses increased $11 million in 2012, primarily due to higher incentive compensation costs and professional fees. General and administrative expenses increased $10 million in 2012, primarily due to higher incentive compensation costs in addition to severance and separation costs as a result of a reduction in staff.
Reinsurance protection.  Sirius Group's reinsurance protection primarily consists of pro-rata and excess of loss protections to cover aviation, trade credit, and certain accident and health and property exposures. Sirius Group's proportional reinsurance programs provide protection for part of the non-proportional treaty accounts written in Europe, the Americas, Asia, the Middle East and Australia.  This reinsurance is designed to increase underwriting capacity where appropriate, and to reduce exposure both to large catastrophe losses and to a frequency of smaller loss events.  Attachment points and coverage limits vary by region around the world.
Sirius Group's gross combined ratio was lower than the net combined ratio by 6 points for 2012 and 7 points for 2011.  The higher net combined ratio for 2012 was primarily due to the cost of property retrocessions with limited ceded property loss recoveries. The higher net combined ratio for 2011 was due to the Japan and New Zealand earthquake losses, very little of which were ceded under Sirius Group's retrocessional reinsurance coverage, in addition to the cost of the property retrocessions. 

Sirius Group Results—Year Ended December 31, 2011 versus Year Ended December 31, 2010
Sirius Group's GAAP combined ratio was 100% for 2011 compared to 94% for 2010.  Both years were impacted by significant catastrophe losses as the 2011 GAAP combined ratio included 24 points of catastrophe losses compared to 23 points in 2010. For 2011, catastrophe losses included $81 million (9 points) of losses from the Japan earthquake and tsunami, $51 million (6 points) of losses from the February and June 2011 New Zealand earthquakes, $34 million (4 points) from floods in Thailand, and $25 million (3 points) of losses from severe weather and tornados in the Midwestern United States.  Catastrophe losses for 2010 were primarily due to the Chile and New Zealand earthquakes, European floods and Deepwater Horizon.  Favorable net loss reserve development for 2011 was 5 points, primarily attributable to $41 million of favorable development on property lines, including $13 million of loss reserve reductions for the 2010 Chile earthquake, partially offset by asbestos and environmental increases of $12 million. Favorable loss reserve development for 2010 was 7 points, mostly from short-tailed lines of business, primarily property, accident and health, and marine. The increase in the 2011 GAAP combined ratio also reflects worse current accident year underwriting results in the accident and health, marine, and aviation lines, partially offset by improved underwriting results in the trade credit line.

54


Sirius Group's gross written premiums increased 5% (2% in local currencies) to $1,128 million in 2011 from $1,079 million in 2010, while net written premiums increased 6% (3% in local currencies) to $916 million in 2011 from $866 million in 2010.  These increases were primarily due to increases in the accident and health and trade credit lines of business and foreign exchange translation.  Earned premiums increased 8% (5% in local currencies) to $912 million in 2011 from $848 million in 2010.  In addition to the changes noted above for written premiums, earned premiums increased due to a change in business mix. Trade credit and accident and health premiums, which have a longer earnings recognition period than Sirius Group's other writings, have been an increasingly higher percentage of Sirius Group's total written premiums in recent years.
Sirius Group's other revenues consisted primarily of $6 million of foreign currency translation losses recorded in 2011 compared to $28 million of foreign currency translation gains in 2010.  Additionally, Sirius Group acquired the loss reserve portfolio of Old Lyme and recorded a pre-tax gain of approximately $7 million in other revenues in 2011, which reflects the excess of the fair value of the net assets acquired over the consideration paid. In 2010, Sirius Group acquired Central National and recorded a pre-tax gain of approximately $13 million in other revenues.
Sirius Group's other underwriting expenses increased $6 million in 2011, primarily due to foreign exchange, higher professional fees mainly from systems initiatives, somewhat offset by lower incentive compensation costs. 
Reinsurance protection.  Sirius Group's net combined ratio for 2011 was higher than its gross combined ratio by 7 points and the net combined ratio was lower than the gross combined ratio by 6 points for 2010.  The higher net combined ratio for 2011 was due to the Japan and New Zealand earthquake losses, very little of which were ceded under Sirius Group's retrocessional reinsurance coverage, in addition to the cost of the property retrocessions. The lower net combined ratio for 2010 was primarily due to significant retrocessional recoveries, including recovery of the full $65 million limit under Sirius Group's non-U.S./non-Japan earthquake cover triggered by losses from the Chile earthquake.

HG Global reported pre-tax income of $14 million in 2012, which was driven by $18 million of interest income on the BAM Surplus Notes, partially offset by startup and operational costs. BAM reported $36 million in pre-tax losses in 2012 that were driven by $18 million of interest expense on the BAM Surplus Notes and startup and operational costs. Since BAM is a mutual insurance company owned by its members, BAM's results do not affect White Mountains' adjusted book value per share as they are attributed to non-controlling interests.

Other Operations Results—Year December 31, 2012 versus Year Ended December 31, 2011
White Mountains’ Other Operations segment reported pre-tax income of $8 million in 2012 compared to a pre-tax loss of $103 million in 2011.  The improvement in the 2012 results was driven by an improvement in the mark-to-market performance of the Symetra warrants, higher pre-tax income from investments, lower incentive compensation expenses and lower losses from WM Life Re. 2011 included a higher level of incentive compensation expenses as a result of the gain from the Esurance Sale and a 35% increase in White Mountains’ stock price during 2011 compared to a 14% increase in 2012.  The value of White Mountains' investment in Symetra warrants increased $18 million in 2012 compared to a decrease of $25 million in 2011. WM Life Re reported pre-tax loss of $19 million in 2012 compared to pre-tax loss of $27 million in 2011. See Note 8 - Variable Annuity Reinsurance for details regarding WM Life Re’s total impact on White Mountains’ statement of operations.
Share repurchases. White Mountains repurchased and retired 1,329,640 of its common shares for $669 million in 2012 at an average price per share of $503.09, or approximately 86% of White Mountains' December 31, 2012 adjusted book value per share.

Other Operations Results—Year Ended December 31, 2011 versus Year Ended December 31, 2010
White Mountains’ Other Operations segment reported pre-tax loss of $103 million in 2011 compared to a pre-tax loss of $100 million in 2010.  The increase in the pre-tax loss in 2011 was driven by higher mark-to-market losses on the Symetra warrants and higher incentive compensation expenses, partially offset by lower losses from WM Life Re.
The value of White Mountains’ investment in Symetra warrants decreased $25 million in 2011 compared to a decrease of $1 million in 2010. WM Life Re reported pre-tax losses $27 million 2011 compared to $61 million of pre-tax loss in 2010.  During the fourth quarter of 2011, WM Life Re reported approximately $13 million of losses from changes in assumptions used to calculate the value of its variable annuity guarantee liabilities, including a $7 million loss due to lower surrender assumptions.  During 2010, WM Life Re reported $48 million in losses from reductions in surrender assumptions.
Share repurchases. White Mountains repurchased and retired 646,502 of its common shares for $253 million in 2011 at an average share price of $390, which was approximately 72% of White Mountains' December 31, 2011 adjusted book value per share.

Investment Returns—Year Ended December 31, 2012 versus Year Ended December 31, 2011
White Mountains’ GAAP pre-tax total return on invested assets was 4.9% for 2012, which includes 0.5% of foreign currency gains, compared to 2.9% for 2011, which includes 0.2% of foreign currency losses. White Mountains’ high-quality, short-duration, fixed income portfolio returned 4.4% (3.8% in local currencies) for 2012, outperforming the Barclays U.S. Intermediate Aggregate Index return of 3.6%. White Mountains’ fixed income portfolio returned 3.1% for 2011, trailing the benchmark of 6.0% as rates declined during 2011. White Mountains’ value-oriented equity portfolio, approximately 19% of GAAP invested assets at December 31, 2012, returned 7.7% for 2012, compared to the S&P 500 Index return of 16.0%, while the equity portfolio returned 1.4% in 2011, compared to the S&P 500 Index return of 2.1%.  The underperformance against the benchmark in both periods reflects large positions in other long-term investments and convertible fixed maturity investments (as opposed to common equity securities), which tend to lag the index in strong markets. It also reflects underweight exposure in common equity and convertible securities to the technology, consumer discretionary, and industrial sectors and an overweight position in materials, in particular gold mining stocks, relative to the S&P 500 Index.
Net investment income was down 17% to $154 million in 2012, due primarily to a lower invested asset base driven by share repurchases and lower fixed maturity yields.
WM Advisors has a sub-advisory agreement with Prospector, a registered investment adviser, under which Prospector manages most of White Mountains’ publicly-traded common equity securities and convertible fixed maturity securities. Total annualized returns for White Mountains’ equity portfolio managed by Prospector compared to the annualized total returns of the S&P 500 Index are as follows:

Investment Returns—Year Ended December 31, 2011 versus Year Ended December 31, 2010
White Mountains’ GAAP pre-tax total return on invested assets was 2.9% for 2011, which includes 0.2% of foreign currency losses, compared to 5.0% for 2010, which includes 0.5% of foreign currency gains. White Mountains’ fixed income portfolio returned 3.1% for 2011, lagging the Barclays U.S. Intermediate Aggregate Index return of 6.0%. White Mountains’ high-quality, short-duration fixed income portfolio trailed the longer-duration benchmark as rates declined during 2011.  White Mountains’ equity portfolio, approximately 14% of GAAP invested assets at December 31, 2011, returned 1.4% for 2011, compared to the S&P 500 Index return of 2.1%, while the equity portfolio returned 12.6% in 2010, compared to the S&P 500 Index return of 15.1%.  White Mountains’ equity portfolio included convertible fixed maturity investments whose returns were hurt by rising credit spreads on the fixed maturity component of the instruments.
Net investment income was down 12% to $185 million in 2011, due primarily to lower fixed maturity yields and a lower invested asset base in the first nine months of 2011, partially offset by the effect of the increase in invested assets during the fourth quarter of 2011 as a result of the Esurance Sale.

Symetra Common Shares
During 2012, White Mountains recorded $30 million in after-tax equity in earnings from its investment in Symetra's common shares, which increased the value of the investment in Symetra's common shares used in the calculation of White Mountains' adjusted book value per share to $16.58 per Symetra common share at December 31, 2012, compared to Symetra's quoted stock price of $12.98 and Symetra's book value per common share excluding unrealized gains and losses from its fixed maturity investment portfolio of $18.97.
White Mountains accounts for its investment in common shares of Symetra using the equity method. Under the equity method, the GAAP carrying value of White Mountains' investment in Symetra common shares is normally equal to the percentage of Symetra's GAAP book value represented by White Mountains' common share ownership, which was 15% at December 31, 2012 and 2011. At December 31, 2011, White Mountains concluded that its investment in Symetra common shares was other-than-temporarily impaired and wrote down the GAAP book value of the investment to its estimated fair value of $261 million, or $15 per share at December 31, 2011, which resulted in $46 million of after-tax equity in losses of unconsolidated affiliates and $137 million of after-tax equity in net unrealized losses of unconsolidated affiliates. The write-down reduced adjusted book value per share by approximately $6. Under GAAP, a decline in the fair value of an investment is considered to be other-than-temporary when the fair value of the investment is not expected to recover to its GAAP carrying value in the near term. White Mountains concluded that the accounting impairment on its investment in Symetra common shares existed due to the prolonged low interest rate environment in which life insurance companies currently operate and not from reasons specific to Symetra itself. As a result, White Mountains does not believe that the accounting impairment equates to an impairment in Symetra's long-term intrinsic business value. See “White Mountains’ Investment in Symetra Common Shares” under CRITICAL ACCOUNTING ESTIMATES on page 100.

Impact of Foreign Currency on Investment Returns
White Mountains’ foreign assets and liabilities are valued using period-end exchange rates, and its foreign revenues and expenses are valued using average exchange rates over the period. Foreign currency exchange rate risk is the risk that White Mountains will incur losses on a U.S. dollar basis due to adverse changes in foreign currency exchange rates. See “Foreign Currency Exchange Risk” on page 105.
A summary of the impact of foreign currency translation on White Mountains’ consolidated financial results for the years ended December 31, 2012, 2011 and 2010 follows:

(1) Component of net realized and unrealized investments gains on the income statement.

At December 31, 2012, White Mountains’ investment portfolio included approximately $1.2 billion in non-U.S. dollar-denominated investments, most of which are held at Sirius International and denominated in Swedish kronor or euros. The value of the investments in this portfolio is impacted by changes in the exchange rate between the U.S. dollar and the kronor and between the U.S. dollar and the euro.  During 2012, the U.S. dollar weakened 6% against the kronor and 2% against the euro.  These currency movements resulted in approximately $38 million of pre-tax foreign currency investment gains for the year ended December 31, 2012, which are recorded as components of net realized and unrealized investment gains and unrealized foreign currency gains and losses on investments.  During 2011, the U.S. dollar strengthened 3% against the kronor and 3% against the euro, which resulted in $21 million of pre-tax foreign currency losses for the year.  During 2010, the U.S. dollar weakened 6% against the kronor and strengthened 7% against the euro, which resulted in $32 million of pre-tax foreign currency gains for the year.

59


Sirius International holds a large portfolio of investments that are denominated in U.S. dollars, but its functional currency is the Swedish kronor. When Sirius International prepares its stand-alone GAAP financial statements, it translates its U.S. dollar-denominated investments to Swedish kronor and recognizes the related foreign currency translation gains or losses through income. When White Mountains consolidates Sirius International, it translates Sirius International’s stand-alone GAAP financial statements to U.S. dollars and recognizes the foreign currency gains or losses arising from this translation, including those associated with Sirius International’s U.S. dollar-denominated investments, through other comprehensive income.  Since White Mountains reports its financial statements in U.S. dollars, there is no net effect to adjusted book value per share or to investment returns from foreign currency translation on its U.S. dollar-denominated investments at Sirius International.  However, net realized and unrealized investment gains, other revenues and other comprehensive income can be significantly affected during periods of high volatility in the foreign exchange rate between the U.S. dollar and the Swedish kronor.
The amount of foreign currency translation on Sirius International’s U.S. dollar denominated investments recognized as a decrease of net income and an increase of other comprehensive income was $40 million in 2012. The amount of foreign currency translation on Sirius International’s U.S. dollar denominated investments recognized as an increase of net income and decrease of other comprehensive income was $25 million in 2011. The amount of foreign currency translation on Sirius International’s U.S. dollar denominated investments recognized as a decrease of net income and an increase of other comprehensive income was $49 million in 2010.

White Mountains’ investment portfolio consists of debt and equity securities issued in over 30 countries worldwide. The United States represents the country of issue for 76% of White Mountains’ fixed maturity, common equity and convertible fixed maturity investment portfolio. White Mountains has minimal sovereign risk exposure to European peripheral countries such as Ireland, Greece, Portugal, Spain and Italy (“peripheral countries”). White Mountains’ portfolio includes 0.6% of total fixed maturity, convertible fixed maturity and common equity investments issued from these peripheral countries at December 31, 2012.  However, White Mountains may have indirect exposure to peripheral countries through securities issued from non-peripheral countries as the issuers of those securities could have exposure to peripheral countries.

LIQUIDITY AND CAPITAL RESOURCES

Operating Cash and Short-term Investments
Holding company level.  The primary sources of cash for the Company and certain of its intermediate holding companies are expected to be distributions and tax sharing payments received from its insurance and reinsurance operating subsidiaries, capital raising activities, net investment income and proceeds from sales and maturities of investments. The primary uses of cash are expected to be repurchases of the Company’s common shares, payments on and repurchases/retirements of its debt obligations, dividend payments to holders of the Company’s common shares, to non-controlling interest holders of OneBeacon Ltd.’s common shares and to holders of the SIG Preference Shares, purchases of investments, payments made to tax authorities, contributions to operating subsidiaries and operating expenses.
Operating subsidiary level.  The primary sources of cash for White Mountains’ insurance and reinsurance operating subsidiaries are expected to be premium collections, net investment income, proceeds from sales and maturities of investments, contributions from holding companies and capital raising activities. The primary uses of cash are expected to be claim payments, policy acquisition costs, purchases of investments, payments on and repurchases/retirements of its debt obligations, distributions and tax sharing payments made to holding companies and operating expenses.
Both internal and external forces influence White Mountains’ financial condition, results of operations and cash flows. Claim settlements, premium levels and investment returns may be impacted by changing rates of inflation and other economic conditions. In many cases, significant periods of time, sometimes several years or more, may lapse between the occurrence of an insured loss, the reporting of the loss to White Mountains and the settlement of the liability for that loss. The exact timing of the payment of claims and benefits cannot be predicted with certainty. White Mountains’ insurance and reinsurance operating subsidiaries maintain portfolios of invested assets with varying maturities and a substantial amount of cash and short-term investments to provide adequate liquidity for the payment of claims.
Management believes that White Mountains’ cash balances, cash flows from operations, routine sales and maturities of investments and the liquidity provided by the WTM Bank Facility are adequate to meet expected cash requirements for the foreseeable future on both a holding company and insurance and reinsurance operating subsidiary level.

Dividend Capacity
 
Under the insurance laws of the states and jurisdictions that White Mountains’ insurance and reinsurance operating subsidiaries are domiciled, an insurer is restricted with respect to the timing and the amount of dividends it may pay without prior approval by regulatory authorities. Accordingly, there can be no assurance regarding the amount of such dividends that may be paid by such subsidiaries in the future. Following is a description of the dividend capacity of White Mountains’ insurance and reinsurance operating subsidiaries:
 
OneBeacon:
Generally, OneBeacon's top tier regulated insurance operating subsidiaries have the ability to pay dividends during any 12-month period without the prior approval of regulatory authorities in an amount set by formula based on the greater of prior year statutory net income or 10% of prior year end statutory surplus, subject to the availability of unassigned funds. OneBeacon Insurance Company (“OBIC”), OneBeacon's primary top tier regulated insurance operating subsidiary, has the ability to pay $330 million of dividends during 2013 (based on its 2012 statutory net income of $330 million) without prior approval of regulatory authorities, subject to the availability of unassigned funds. The amount of dividends available to be paid by OBIC in any given year is also subject to cash flow and earnings generated by OBIC's business, which now just comprises the Runoff Business, as well as to dividends received from its subsidiaries, including Atlantic Specialty Insurance Company (“ASIC”). At December 31, 2012, OBIC had $0.7 billion of unassigned funds and $0.9 billion of statutory surplus.
As disclosed in Note 2 - “Significant Transactions” of the accompanying consolidated financial statements, during the fourth quarter of 2012, OneBeacon executed various intercompany reinsurance agreements which, along with other internal capital transactions among our insurance operating subsidiaries, resulted in ASIC becoming the lead insurance company for the ongoing specialty business and OBIC becoming the lead insurance company for the Runoff Business. Notwithstanding these restructuring transactions, OneBeacon continues to manage its statutory capital on a combined basis. Although OBIC remains a top tier regulated insurance operating subsidiary and maintains sufficient statutory capital to support the Runoff Business, the majority of the group's statutory capital is now included in ASIC to support the ongoing specialty business.
ASIC has the ability to pay dividends during any 12-month period without the prior approval of regulatory authorities in an amount set by formula based on the lesser of net investment income, as defined by statute, or 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus. Given the changes in structure noted above, ASIC will likely require prior approval by regulatory authorities in order to pay dividends until it builds up a historical net investment income stream and earned surplus balance under its new structure. At December 31, 2012, ASIC had negative earned surplus and $0.7 billion of statutory surplus.
During 2012, OneBeacon's top tier regulated insurance operating subsidiaries paid $173 million of dividends to their immediate parent, which included the distribution of a regulated insurance subsidiary with a value of $34 million.
During 2012, OneBeacon's unregulated insurance operating subsidiaries paid $5 million of dividends to their immediate parent. At December 31, 2012, OneBeacon's unregulated insurance operating subsidiaries had $29 million of net unrestricted cash, short-term investments and fixed maturity investments.
During 2012, OneBeacon Ltd. paid $80 million of regular quarterly dividends to its common shareholders. White Mountains received $60 million of these dividends.
At December 31, 2012, OneBeacon Ltd. and its intermediate holding companies had $272 million of net unrestricted cash, short-term investments and fixed maturity investments and $33 million of common equity securities and convertible fixed maturity investments outside of its regulated and unregulated insurance operating subsidiaries.

Sirius Group:
Subject to certain limitations under Swedish law, Sirius International is permitted to transfer a portion of its pre-tax income to its Swedish parent companies to minimize taxes (referred to as a group contribution). In 2012, Sirius International transferred $82 million of its 2011 pre-tax income to its Swedish parent companies as a group contribution. In 2013, Sirius International currently intends to transfer approximately $110 million (based on the December 31, 2012 SEK to USD exchange rate) of its 2012 pre-tax income to its Swedish parent companies as a group contribution.
Sirius International has the ability to pay dividends subject to the availability of unrestricted statutory surplus. Historically, Sirius International has allocated the majority of its pre-tax income, after group contributions to its Swedish parent companies, to the Safety Reserve (see “Safety Reserve” below). At December 31, 2012, Sirius International had $852 million (based on the December 31, 2012 SEK to USD exchange rate) of unrestricted statutory surplus, which is available for distribution in 2013. The amount of dividends available to be paid by Sirius International in any given year is also subject to cash flow and earnings generated by Sirius International’s business, as well as to dividends received from its subsidiaries, including Sirius America. During 2012, Sirius International distributed $24 million of dividends to its immediate parent and declared an additional $75 million of dividends at December 31, 2012 (for a total of $99 million). The $75 million was paid in January 2013. In 2013, Sirius International currently intends to distribute an additional $50 million of dividends to its immediate parent.

64


Sirius America has the ability to pay dividends during any twelve-month period without the prior approval of regulatory authorities in an amount set by formula based on the lesser of net investment income, as defined by statute, or 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus. Based upon 2012 statutory net investment income, Sirius America has the ability to pay $15 million of dividends during 2013 without prior approval of regulatory authorities, subject to the availability of earned surplus.  At December 31, 2012, Sirius America had $56 million of earned surplus and $528 million of statutory surplus.  In 2012, Sirius America paid $55 million of dividends to its immediate parent.
During 2012, Sirius Group distributed $40 million to its immediate parent and declared an additional $75 million at December 31, 2012 (for a total of $115 million). The $75 million was paid in January 2013.
At December 31, 2012, Sirius Group and its intermediate holding companies had $72 million of net unrestricted cash, short-term investments and fixed maturity investments and $18 million of other long-term investments outside of its regulated and unregulated insurance and reinsurance operating subsidiaries.

Sirius Group 2011 Reorganization
During the fourth quarter of 2011, White Mountains completed a rebranding and reorganization (the “Reorganization”) of its reinsurance business. As part of the Reorganization, White Mountains' reinsurance businesses adopted the Sirius name globally and Sirius America (formerly WMRe America) became a wholly owned subsidiary of Sirius International (formerly WMRe Sirius). In connection with the Reorganization, A.M. Best upgraded the financial strength rating of Sirius America from “A-” (Excellent, the fourth highest of sixteen ratings) to a group “A” (Excellent, the third highest of sixteen ratings), consistent with Sirius International's rating, and all financial strength ratings from the four major ratings agencies were affirmed with stable outlook. Additionally, A.M. Best upgraded the creditworthiness ratings from “bbb-” (Adequate, the tenth highest of twenty-two ratings) on the SIG Senior Notes to “bbb” (Adequate, the ninth highest of twenty-two ratings) and from “bb” (Speculative, the twelfth highest of twenty-two ratings) on the SIG Preference Shares to “bb+” (Speculative, the eleventh highest of twenty-two ratings).  S&P upgraded the creditworthiness ratings from “BBB-” (Adequate, the tenth highest of twenty-two ratings) on the SIG Senior Notes to “BBB” (Adequate, the ninth highest of twenty-two ratings) and from “BB” (Speculative, the twelfth highest of twenty-two ratings) on the SIG Preference Shares to “BB+” (Speculative, the eleventh highest of twenty-two ratings). 
In conjunction with the Reorganization, the following capital transactions occurred in October 2011: 
·        Sirius America paid $250 million to its immediate parent, which included $67 million of dividends and a $183 million return of capital;
·        Sirius International paid $169 million to an intermediate holding company of Sirius Group for a portion of Sirius America.
·        An intermediate holding company of Sirius Group contributed the remaining shares of Sirius America with a GAAP book value of $436 million to Sirius International, which subsequently owned 100% of the shares of Sirius America;
·        Sirius Group distributed $425 million to White Mountains, which included approximately $300 million that was freed up at Sirius International and Sirius America as a result of the Reorganization and the commutation of quota-share agreements between Sirius Group and Esurance as a result of the Esurance Sale;
·        White Mountains contributed a portion of its common share investment in Symetra to an intermediate holding company of Sirius Group.  At December 31, 2011, White Mountains' entire common share investment in Symetra, which had a carrying value of $261 million, was held by Sirius Group.

Capital Maintenance
In connection with Sirius Group's reorganization in October 2011, Sirius International and Sirius America entered into a capital maintenance agreement, which obligates Sirius International to make contributions to Sirius America's surplus in order for Sirius America to maintain surplus equal to at least 125% of the company action level risk based capital as defined in the NAIC Property/Casualty Risk-Based Capital Report. The agreement provides for a maximum contribution to Sirius America of $200 million.  Sirius International also provides Sirius America with accident year stop loss reinsurance, which protects Sirius America's accident year loss and allocated loss adjustment expense ratio in excess of 70%, with a limit of $110 million.

Safety Reserve
Subject to certain limitations under Swedish law, Sirius International is permitted to transfer pre-tax income amounts into an untaxed reserve referred to as a safety reserve. At December 31, 2012, Sirius International's safety reserve amounted to SEK 9.6 billion, or $1.5 billion (based on the December 31, 2012 SEK to USD exchange rate). Under GAAP, an amount equal to the safety reserve, net of a related deferred tax liability established at the Swedish tax rate, is classified as shareholder’s equity. The tax rate in effect on December 31, 2011 was 26.3%. The tax rate utilized on December 31, 2012 was the new Swedish tax rate of 22.0%. Generally, this deferred tax liability is only required to be paid by Sirius International if it fails to maintain prescribed levels of premium writings and loss reserves in future years. As a result of the indefinite deferral of these taxes, Swedish regulatory authorities do not apply any taxes to the safety reserve when calculating solvency capital under Swedish insurance regulations. Accordingly, under local statutory requirements, an amount equal to the deferred tax liability on Sirius International's safety reserve ($327 million at December 31, 2012) is included in solvency capital. Access to the safety reserve is restricted to coverage of reinsurance losses. Access for any other purpose requires the approval of Swedish regulatory authorities. Similar to the approach taken by Swedish regulatory authorities, most major rating agencies generally include the $1.5 billion balance of the safety reserve, without any provision for deferred taxes, in Sirius International's capital when assessing Sirius International's financial strength.
 
HG Global/BAM:
HG Global has $613 million face value of preferred shares outstanding, of which White Mountains owns 97.3%. Holders of the HG Global preferred shares receive cumulative dividends at a fixed annual rate of 6.0% on a quarterly basis, when and if declared by HG Global. HG Global did not declare or pay any preferred dividends in 2012. As of December 31, 2012, HG Global has accrued $16.8 million of dividends payable to holders of its preferred shares, $16.3 million of which is payable to White Mountains and eliminated in consolidation.
HG Re is a Special Purpose Insurer subject to regulation and supervision by the BMA, but does not require regulatory approval to pay dividends. However, HG Re’s dividend capacity is limited by amounts held in the collateral trusts pursuant to the FLRT with BAM. As of December 31, 2012, HG Re had statutory capital of $412 million, of which $12 million (which partially relates to accrued interest on the BAM Surplus Notes held by HG Re) was available for dividends to HG Global and $400 million was held as collateral in the Supplemental Trust pursuant to the FLRT with BAM.
Interest on the BAM Surplus Notes is payable quarterly at a fixed annual rate of 8.0%. Interest and principal payments are subject to approval of the New York State Department of Financial Services. BAM did not pay any interest on the BAM Surplus Notes in 2012. As of December 31, 2012, HG Global has accrued $18.4 million of interest receivable on the BAM Surplus Notes.

Other Operations:
During 2012, WM Advisors did not pay any dividends to its immediate parent. At December 31, 2012, WM Advisors had approximately $18 million of net unrestricted cash and short-term investments.
At December 31, 2012, the Company and its intermediate holding companies had $132 million of net unrestricted cash, short-term investments and fixed maturity investments, $540 million of common equity securities and $78 million of other long-term investments included in its Other Operations segment. During 2012, White Mountains paid a $7 million common share dividend.

Insurance Float

Insurance float is an important aspect of White Mountains’ insurance operations. Insurance float represents funds that an insurance or reinsurance company holds for a limited time. In an insurance or reinsurance operation, float arises because premiums are collected before losses are paid. This interval can extend over many years. During that time, the insurer or reinsurer invests the funds. When the premiums that an insurer or reinsurer collects do not cover the losses and expenses it eventually must pay, the result is an underwriting loss, which is considered to be the cost of insurance float.  One manner in which White Mountains calculates its insurance float is by taking its net investment assets and subtracting its total adjusted capital. Although insurance float can be calculated using numbers determined under GAAP, insurance float is not a GAAP concept and, therefore, there is no comparable GAAP measure.

66


Insurance float can increase in a number of ways, including through acquisitions of insurance and reinsurance operations, organic growth in existing insurance and reinsurance operations and recognition of losses that do not cause a corresponding reduction in investment assets.  Conversely, insurance float can decrease in a number of other ways, including sales of insurance and reinsurance operations, shrinking or runoff of existing insurance and reinsurance operations, the acquisition of operations that do not have substantial investment assets (e.g., an agency) and the recognition of gains that do not cause a corresponding increase in investment assets.  White Mountains has historically obtained its insurance float primarily through acquisitions, as opposed to organic growth. It is White Mountains’ intention to generate low-cost float over time through a combination of acquisitions and organic growth in its existing insurance and reinsurance operations. However, White Mountains will seek to increase its insurance float organically only when market conditions allow for an expectation of generating underwriting profits.
Certain operational leverage metrics can be measured with ratios that are calculated using insurance float.  There are many activities that do not change the amount of insurance float at an insurance company but can have a significant impact on the company’s operational leverage metrics.  For example, investment gains and losses, foreign currency gains and losses, debt issuances and repurchases/repayments, common and preferred share issuances and repurchases and dividends paid to shareholders are all activities that do not change insurance float but that can meaningfully impact operational leverage metrics.
The following table illustrates White Mountains’ consolidated insurance float position as of December 31, 2012 and 2011:

(1) The non-controlling interest arising from White Mountains’ investments in consolidated limited partnerships has not been included in total capital because White Mountains does not have the ability to utilize the assets supporting this non-controlling interest in its insurance operations or in support of its debt obligations.

(3) Excludes funds held by ceding companies from which White Mountains does not receive interest credits.
(4) Excludes funds held by White Mountains under reinsurance treaties for which White Mountains does not provide interest credits.


67


During 2012, insurance float decreased by $480 million, primarily due to the AutoOne Sale and the continued runoff of reserves at OneBeacon and Sirius America, the final settlement and commutation of Scandinavian Re’s multi-year retrocessional Casualty Aggregate Stop Loss Agreement with St. Paul, as well as commutations and runoff of Sirius Group's casualty business and payments of losses incurred in 2010 and 2011 related to major catastrophes, primarily from earthquakes in Chile, Japan and New Zealand.  These catastrophe losses increased White Mountains’ insurance float when they were first recorded, which is now reversing and decreasing insurance float as the catastrophe losses are paid. These decreases in insurance float were partially offset by an increase in float resulting from the $101 million in after tax losses recognized at OneBeacon related to the Runoff Transaction and $113 million of after tax catastrophe losses recognized by White Mountains in 2012, primarily due to hurricane Sandy. Based on December 31, 2012 balances, the closing of the Runoff Transaction is expected to decrease insurance float by approximately $340 million.

The non-controlling interest arising from White Mountains’ investments in consolidated limited partnerships has not been included in total
capital because White Mountains does not have the ability to utilize the assets supporting this non-controlling interest in its insurance
operations or in support of its debt obligations.
(2) 
Includes the regulatory capital represented by the deferred tax liability on the safety reserve at Sirius International (See “Safety
Reserve” on page 66) of $327 and $370 at December 31, 2012 and 2011,

Management believes that White Mountains has the flexibility and capacity to obtain funds externally as needed through debt or equity financing on both a short-term and long-term basis. However, White Mountains can provide no assurance that, if needed, it would be able to obtain additional debt or equity financing on satisfactory terms, if at all.
White Mountains has a revolving credit facility with a syndicate of lenders administered by Bank of America, N.A. with a total commitment of $375 million (the “WTM Bank Facility”) that has a maturity date of August 12, 2015. As of December 31, 2012, White Mountains had $75 million outstanding under the WTM Bank Facility, which the Company repaid in January 2013.
The WTM Bank Facility contains various affirmative, negative and financial covenants that White Mountains considers to be customary for such borrowings, including certain minimum net worth and maximum debt to capitalization standards. Failure to meet one or more of these covenants could result in an event of default, which ultimately could eliminate availability under this facility and result in acceleration of principal repayment on any amounts outstanding. At December 31, 2012, White Mountains was in compliance with all of the covenants under the WTM Bank Facility and anticipates it will continue to remain in compliance with these covenants for the foreseeable future.

68


It is possible that, in the future, one or more of the rating agencies may lower White Mountains’ existing ratings. If one or more of its ratings were lowered, White Mountains could incur higher borrowing costs on future borrowings and its ability to access the capital markets could be impacted. In addition, White Mountains’ insurance and reinsurance operating subsidiaries could be adversely impacted by a lowering of their financial strength ratings, including a possible reduction in demand for their products in certain markets.
In November 2012, OBH issued $275 million face value of senior unsecured debt through a public offering, at an issue price of 99.9%. The net proceeds from the issuance of the 2012 OBH Senior Notes were used to repurchase the remaining 2003 OBH Senior Notes. The 2012 OBH Senior Notes, which are fully and unconditionally guaranteed as to the payment of principal and interest by OneBeacon Ltd., bear an annual interest rate of 4.60%, payable semi-annually in arrears on May 9 and November 9, until maturity on November 9, 2022.

The 2012 OBH Senior Notes and the SIG Senior Notes were issued under indentures that contain restrictive covenants which, among other things, limit the ability of OneBeacon, Ltd., OBH, SIG and their respective subsidiaries to create liens and enter into sale and leaseback transactions and limits the ability of OneBeacon, Ltd., OBH, SIG and their respective subsidiaries to consolidate, merge or transfer their properties and assets. The indentures do not contain any financial ratios or specified levels of net worth or liquidity to which OneBeacon, Ltd., OBH or SIG must adhere. At December 31, 2012, OneBeacon, Ltd., OBH and SIG were in compliance with all of the covenants under the 2012 OBH Senior Notes and the SIG Senior Notes, and anticipates it will continue to remain in compliance with these covenants for the foreseeable future.

Capital Lease
In December 2011, OneBeacon Insurance Company (“OBIC”), an indirect wholly-owned subsidiary of OneBeacon Ltd., sold the majority of its fixed assets and capitalized software to OneBeacon Services LLC (“OB Services”), another indirect wholly-owned subsidiary of OneBeacon Ltd. The fixed assets and capitalized software were sold at a cost equal to book value with no gain or loss recorded on the sale. Subsequent to purchasing the fixed assets and capitalized software from OBIC, OB Services entered into lease financing arrangements with US Bancorp Equipment Finance, Inc. (“US Bancorp”) and Fifth Third Equipment Finance Company (“Fifth Third”) whereby OB Services sold its fixed assets and its capitalized software, respectively, to US Bancorp and Fifth Third. The assets were sold at a cost equal to net book value. OB Services then leased the fixed assets back from US Bancorp for a lease term of five years and leased the capitalized software back from Fifth Third for a lease term of four years. OB Services received cash proceeds of $23 million as a result of entering into the sale-leaseback transactions. At the end of the lease terms, OB Services will be obligated to purchase the leased assets for a nominal fee, after which all rights, title and interest would transfer to OB Services. At December 31, 2012, OB Services has recorded a capital lease obligation of $18 million included within other liabilities and a capital lease asset of $16 million included within other assets.

Represents expected future cash outflows resulting from loss and LAE payments. The amounts presented are gross of reinsurance
recoverables on unpaid losses of $429 and include the discount on OneBeacon’s workers compensation loss and LAE reserves of $5 as of
December 31, 2012. These balances exclude amounts included in held for sale as of December 31, 2012 for reinsurance recoverables on
unpaid losses of $1,800, loss and LAE reserves of $2,100 and the remaining purchase accounting fair value adjustment of $150 related to the OneBeacon Acquisition.
(2) 
At December 31, 2012, White Mountains had $75 outstanding under its credit facility that was repaid in January 2013.

White Mountains’ loss reserves do not have contractual maturity dates. However, based on historical payment patterns, the preceding table includes an estimate of when management expects White Mountains’ loss reserves to be paid. The timing of claim payments is subject to significant uncertainty. White Mountains maintains a portfolio of marketable investments with varying maturities and a substantial amount of short-term investments to provide adequate liquidity for the payment of claims.

69


The SIG Preference Shares are not included in the table above as these perpetual preferred shares have no stated maturity date and are redeemable only at the option of SIG. See “Sirius Group’s Preference Shares and Senior Notes” on page 22 for more details.
The balances included in the table above regarding White Mountains’ long-term incentive compensation plans include amounts payable for performance shares and units, as well as deferred compensation balances. Exact amounts to be paid for performance shares cannot be predicted with certainty, as the ultimate amounts of these liabilities are based on the future performance of White Mountains and in some cases the market price of the Company’s and OneBeacon Ltd.’s common shares at the time the payments are made.
The estimated payments reflected in the table are based on current accrual factors (including performance relative to targets and common share price) and assume that all outstanding balances were 100% vested as of December 31, 2012.
There are no provisions within White Mountains’ operating leasing agreements that would trigger acceleration of future lease payments. The capital lease that OneBeacon entered into in conjunction with the sale-leaseback of certain of OneBeacon’s fixed assets and capitalized software contains provisions that could trigger an event of default, including a failure to make payments when due under the capital lease. If an event of default were to occur, the lessor would have a number of remedies available including the acceleration of future lease payments or the possession of the property covered under the lease agreement.
White Mountains does not finance its operations through the securitization of its trade receivables, through special purpose entities or through synthetic leases. Further, except as noted in the following paragraph, White Mountains has not entered into any material arrangements requiring it to guarantee payment of third-party debt or lease payments or to fund losses of an unconsolidated special purpose entity.
Through Sirius International, White Mountains has a long-term investment as a stockholder in LUC Holdings, an entity that has entered into a lease to rent the London Underwriting Center (“LUC”) through 2016. LUC Holdings in turn subleases space in the LUC. In the LUC Holdings stockholders agreement, the stockholders have guaranteed any shortfall between the lease and the sub-leases on a joint and several basis. As a consequence, in recent years the stockholders have funded an operating shortfall of LUC. At December 31, 2012, White Mountains has recorded a liability of $4 million for its share of the expected future shortfall between LUC Holdings’ head lease payments and sub-lease receipts. White Mountains does not believe that future shortfalls, if any, will have a material impact on its results of operations.
White Mountains also has future binding commitments to fund certain other long-term investments. These commitments, which total approximately $125 million, do not have fixed funding dates and are therefore excluded from the table above.
WM Life Re reinsures death and living benefit guarantees associated with certain variable annuities issued in Japan.  WM Life Re has assumed the risk related to a shortfall between the account value and the guaranteed value that must be paid by the ceding company to an annuitant or to an annuitant’s beneficiary in accordance with the underlying annuity contracts. WM Life Re uses derivative instruments, including put options, interest rate swaps, total return swaps and futures contracts on major equity indices, currency pairs and government bonds, to mitigate the risks associated with changes in the fair value of the reinsured variable annuity guarantees. As of December 31, 2012, the total guarantee value was approximately ¥230 billion (approximately $2.7 billion) and the related account values were approximately 87% of this amount.  
The following table represents expected future cash outflows for WM Life Re’s reinsurance contracts.

White Mountains purchases derivative instruments, including futures and over-the-counter option contracts on interest rates, major equity indices, and foreign currencies, to mitigate the risks associated with changes in the fair value of the reinsured variable annuity guarantees. At December 31, 2012, the fair value of these derivative instruments was $98 million. In addition, WM Life Re held approximately $394 million of cash and fixed maturity investments at December 31, 2012 posted as collateral to its reinsurance counterparties.

Share Repurchases
In 2006, White Mountains' board of directors authorized the Company to repurchase up to 1,000,000 of its common shares, from time to time, subject to market conditions. In 2010 and 2012, White Mountains' board of directors authorized the Company to repurchase an additional 600,000 and 1,000,000, respectively, of its common shares, for a total authorization of 2.6 million shares. Shares may be repurchased on the open market or through privately negotiated transactions. The repurchase authorizations do not have a stated expiration date. At December 31, 2012, White Mountains may repurchase an additional 685,496 shares under these board authorizations. In addition, from time to time White Mountains has also repurchased its common shares through tender offers that were separately approved by its board of directors.

70


During 2012, White Mountains repurchased a total of 1,329,640 of its common shares for $669 million at an average share price of $503, which was 86% of White Mountains' adjusted book value per share of $588 at December 31, 2012. These repurchases were comprised of (1) 502,801 common shares repurchased under the board authorization for $256 million at an average share price of $508; (2) 816,829 common shares repurchased through a fixed-price tender offer for $409 million at a share price of $500; and (3) 10,010 common shares repurchased to satisfy employee income tax withholdings, pursuant to employee benefit plans. Shares repurchased pursuant to employee benefit plans do not fall under the board authorization referred to above.
During 2011, White Mountains repurchased a total of 646,502 of its common shares during for $253 million at an average share price of $390, which was 72% of White Mountains' adjusted book value per share of $542 at December 31, 2011. These repurchases were comprised of (1) 313,967 common shares repurchased under the board authorization for $114 million at an average share price of $364; (2) 332,346 common shares repurchased through two “modified Dutch auction” self-tender offers for $139 million at an average share price of $418; and (3) 189 common shares repurchased to satisfy employee income tax withholdings, pursuant to employee benefit plans.

Cash Flows
Detailed information concerning White Mountains’ cash flows during 2012, 2011 and 2010 follows:

Cash flows from operations for the years ended 2012, 2011 and 2010

Net cash flows (used for) provided from continuing operations was $(30) million, $94 million and $29 million in 2012, 2011 and 2010, respectively. Cash flows from continuing operations decreased $124 million from 2011 to 2012 due to declining net investment income, primarily due to a decrease in the overall average invested asset base, the final settlement and commutation of Scandinavian Re’s multi-year retrocessional Casualty Aggregate Stop Loss Agreement with St. Paul, as well as commutations and runoff of Sirius Group's casualty business and payments of losses incurred in 2010 and 2011 related to major catastrophes, primarily from earthquakes in Chile, Japan and New Zealand.  Net cash flows (used for) provided from discontinued operations was $(196) million, $(209) million and $27 million in 2012, 2011 and 2010, respectively. The cash outflows from discontinued operations in 2012 and 2011 were primarily due to the runoff of reserves related to non-specialty commercial lines businesses that OneBeacon has exited since 2010.
White Mountains does not believe that these trends will have a meaningful impact on its future liquidity or its ability to meet its future cash requirements.

Cash flows from investing and financing activities for the year ended December 31, 2012

Financing and Other Capital Activities

TRANSACTIONS WITH RELATED PERSONS

See Note 18—“Transactions with Related Persons” in the accompanying Consolidated Financial Statements.

NON-GAAP FINANCIAL MEASURES

This report includes three non-GAAP financial measures that have been reconciled to their most comparable GAAP financial measures. White Mountains believes these measures to be more relevant than comparable GAAP measures in evaluating White Mountains’ results of operations and financial condition.
Adjusted comprehensive income is a non-GAAP financial measure that excludes the change in equity in net unrealized gains and losses from Symetra’s fixed maturity portfolio, net of applicable taxes, from comprehensive income. In the calculation of comprehensive income under GAAP, fixed maturity investments are marked-to-market while the liabilities to which those assets are matched are not. Symetra attempts to earn a “spread” between what it earns on its investments and what it pays out on its products. In order to try to fix this spread, Symetra invests in a manner that tries to match the duration and cash flows of its investments with the required cash outflows associated with its life insurance and structured settlements products. As a result, Symetra typically earns the same spread on in-force business whether interest rates fall or rise. Further, at any given time, some of Symetra’s structured settlement obligations may extend 40 or 50 years into the future, which is further out than the longest maturing fixed maturity investments regularly available for purchase in the market (typically 30 years). For these long-dated products, Symetra is unable to fully match the obligation with assets until the remaining expected payout schedule comes within the duration of securities available in the market. If at that time, these fixed maturity investments have yields that are lower than the yields expected when the structured settlement product was originally priced, the spread for the product will shrink and Symetra will ultimately harvest lower returns for its shareholders. GAAP comprehensive income increases when rates decline, which would suggest an increase in the value of Symetra - the opposite of what is happening to the intrinsic value of the business. Therefore, White Mountains’ management and Board of Directors use adjusted comprehensive income when assessing Symetra’s quarterly financial performance. In addition, this measure is typically the predominant component of change in adjusted book value per share, which is used in calculation of White Mountains’ performance for both short-term (annual bonus) and long-term incentive plans. The reconciliation of adjusted comprehensive income to comprehensive income is included on page 48.
Adjusted book value per share is a non-GAAP measure which is derived by expanding the GAAP calculation of book value per White Mountains common share to exclude equity in net unrealized gains and losses from Symetra’s fixed maturity portfolio, net of applicable taxes. In addition, the number of common shares outstanding used in the calculation of adjusted book value per share are adjusted to exclude unearned restricted common shares, the compensation cost of which, at the date of calculation, has yet to be amortized. The reconciliation of adjusted book value per share to GAAP book value per share is included on page 47.
Total capital at White Mountains is comprised of White Mountains’ common shareholders’ equity, debt and non-controlling interest in OneBeacon Ltd and the SIG Preference Shares. Total adjusted capital excludes the equity in net unrealized gains and losses from Symetra’s fixed maturity portfolio, net of applicable taxes from total capital. The reconciliation of total capital to total adjusted capital is included on page 67.

CRITICAL ACCOUNTING ESTIMATES

Management’s Discussion and Analysis of Financial Condition and Results of Operations discuss the Company’s consolidated financial statements, which have been prepared in accordance with GAAP. The financial statements presented herein include all adjustments considered necessary by management to fairly present the financial position, results of operations and cash flows of White Mountains.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Certain of these estimates are considered critical in that they involve a higher degree of judgment and are subject to a significant degree of variability. On an ongoing basis, management evaluates its estimates, including those related to fair value measurements of investments and other financial instruments, valuation of liabilities associated with an assumed reinsurance agreement covering benefit guarantees on variable annuities in Japan, its property-casualty loss and LAE reserves and its property-casualty reinsurance contracts. Management bases it estimates on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.

1. Loss and LAE Reserves

General
White Mountains establishes loss and LAE reserves that are estimates of amounts needed to pay claims and related expenses in the future for insured events that have already occurred. The process of estimating reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain.
Loss and LAE reserves are typically comprised of (1) case reserves for claims reported and (2) reserves for losses that have occurred but for which claims have not yet been reported, referred to as incurred but not reported reserves, which include a provision for expected future development on case reserves. Case reserves are estimated based on the experience and knowledge of claims staff regarding the nature and potential cost of each claim and are adjusted as additional information becomes known or payments are made. IBNR reserves are derived by subtracting paid loss and LAE and case reserves from estimates of ultimate loss and LAE. Actuaries estimate ultimate loss and LAE using various generally accepted actuarial methods applied to known losses and other relevant information. Like case reserves, IBNR reserves are adjusted as additional information becomes known or payments are made.
Ultimate loss and LAE are generally determined by extrapolation of claim emergence and settlement patterns observed in the past that can reasonably be expected to persist into the future. In forecasting ultimate loss and LAE with respect to any line of business, past experience with respect to that line of business is the primary resource, but cannot be relied upon in isolation. White Mountains’ own experience, particularly claims development experience, such as trends in case reserves, payments on and closings of claims, as well as changes in business mix and coverage limits, is the most important information for estimating its reserves. External data, available from organizations such as statistical bureaus, consulting firms and reinsurance companies, is sometimes used to supplement or corroborate White Mountains’ own experience, and can be especially useful for estimating costs of new business. For some lines of business, such as “long-tail” coverages discussed below, claims data reported in the most recent accident year is often too limited to provide a meaningful basis for analysis due to the typical delay in reporting of claims. For this type of business, White Mountains uses a selected loss ratio method for the initial accident year or years. This is a standard and accepted actuarial reserve estimation method in these circumstances in which the loss ratio is selected based upon information used in pricing policies for that line of business, as well as any publicly available industry data, such as industry pricing, experience and trends, for that line of business.
Uncertainties in estimating ultimate loss and LAE are magnified by the time lag between when a claim actually occurs and when it is reported and settled. This time lag is sometimes referred to as the “claim-tail”. The claim-tail for most property coverages is typically short (usually a few days up to a few months). The claim-tail for liability/casualty coverages, such as automobile liability, general liability, products liability, multiple peril coverage, and workers compensation, can be especially long as claims are often reported and ultimately paid or settled years, even decades, after the related loss events occur. During the long claims reporting and settlement period, additional facts regarding coverages written in prior accident years, as well as about actual claims and trends may become known and, as a result, White Mountains may adjust its reserves. If management determines that an adjustment is appropriate, the adjustment is booked in the accounting period in which such determination is made in accordance with GAAP. Accordingly, should reserves need to be increased or decreased in the future from amounts currently established, future results of operations would be negatively or positively impacted, respectively.
In determining ultimate loss and LAE, the cost to indemnify claimants, provide needed legal defense and other services for insureds and administer the investigation and adjustment of claims are considered. These claim costs are influenced by many factors that change over time, such as expanded coverage definitions as a result of new court decisions, inflation in costs to repair or replace damaged property, inflation in the cost of medical services and legislated changes in statutory benefits, as well as by the particular, unique facts that pertain to each claim. As a result, the rate at which claims arose in the past and the costs to settle them may not always be representative of what will occur in the future. The factors influencing changes in claim costs are often difficult to isolate or quantify and developments in paid and incurred losses from historical trends are frequently subject to multiple and conflicting interpretations. Changes in coverage terms or claims handling practices may also cause future experience and/or development patterns to vary from the past. A key objective of actuaries in developing estimates of ultimate loss and LAE, and resulting IBNR reserves, is to identify aberrations and systemic changes occurring within historical experience and accurately adjust for them so that the future can be projected reliably. Because of the factors previously discussed, this process requires the use of informed judgment and is inherently uncertain.
White Mountains’ actuaries use several generally accepted actuarial methods to evaluate its loss reserves, each of which has its own strengths and weaknesses. Management places more or less reliance on a particular method based on the facts and circumstances at the time the reserve estimates are made.

74


These methods generally fall into one of the following categories or are hybrids of one or more of the following categories:

Historical paid loss development methods: These methods use historical loss payments over discrete periods of time to estimate future losses. Historical paid loss development methods assume that the ratio of losses paid in one period to losses paid in an earlier period will remain constant. These methods necessarily assume that factors that have affected paid losses in the past, such as inflation or the effects of litigation, will remain constant in the future. Because historical paid loss development methods do not use case reserves to estimate ultimate losses, they can be more reliable than the other methods discussed below that look to case reserves (such as actuarial methods that use reported losses) in situations where there are significant changes in how case reserves are established by a company’s claims adjusters. However, historical paid loss development methods are more leveraged, meaning that small changes in payments have a larger impact on estimates of ultimate losses, than actuarial methods that use reported losses because cumulative loss payments take much longer to equal the expected ultimate losses than cumulative reported amounts. In addition, and for similar reasons, historical paid loss development methods are often slow to react to situations when new or different factors arise than those that have affected paid losses in the past. 
Historical reported loss development methods:  These methods, like historical paid loss development methods, assume that the ratio of losses in one period to losses in an earlier period will remain constant in the future. However, instead of using paid losses, these methods use reported losses (i.e., the sum of cumulative historical loss payments plus outstanding case reserves) over discrete periods of time to estimate future losses. Historical reported loss development methods can be preferable to historical paid loss development methods because they explicitly take into account open cases and the claims adjusters’ evaluations of the cost to settle all known claims. However, historical reported loss development methods necessarily assume that case reserving practices are consistently applied over time. Therefore, when there have been significant changes in how case reserves are established, using reported loss data to project ultimate losses can be less reliable than other methods.
Expected loss ratio methods:  These methods are based on the assumption that ultimate losses vary proportionately with premiums. Expected loss ratios are typically developed based upon the information used in pricing, and are multiplied by the total amount of premiums written to calculate ultimate losses. Expected loss ratio methods are useful for estimating ultimate losses in the early years of long-tailed lines of business, when little or no paid or reported loss information is available.
Adjusted historical paid and reported loss development methods:  These methods take traditional historical paid and reported loss development methods and adjust them for the estimated impact of changes from the past in factors such as inflation, the speed of claim payments or the adequacy of case reserves. Adjusted historical paid and reported loss development methods are often more reliable methods of predicting ultimate losses in periods of significant change, provided the actuaries can develop methods to reasonably quantify the impact of changes.
 
White Mountains performs an actuarial review of its recorded reserves each quarter. White Mountains’ actuaries compare the previous quarter’s estimates of paid loss and LAE, case reserves and IBNR to amounts indicated by actual experience. Differences between previous estimates and actual experience are evaluated to determine whether a given actuarial method for estimating loss and LAE should be relied upon to a greater or lesser extent than it had been in the past. While some variance is expected each quarter due to the inherent uncertainty in loss and LAE, persistent or large variances would indicate that prior assumptions and/or reliance on certain reserving methods may need to be revised going forward.

OneBeacon

OneBeacon, like other insurance companies, categorizes and tracks its insurance reserves by “line of business”, such as automobile liability, multiple peril package business, and workers compensation. Furthermore, OneBeacon regularly reviews the appropriateness of reserve levels at the line of business level, taking into consideration the variety of trends that impact the ultimate settlement of claims for the subsets of claims in each particular line of business.
In its selection of recorded reserves, OneBeacon historically gave greater weight to adjusted paid loss development methods, which are not dependent on the consistency of case reserving practices, over methods that rely on reported losses. In recent years, the amount of weight given to methods based on reported losses has increased with OneBeacon’s confidence that its case reserving practices have been more consistently applied.

75


Upon completion of each quarterly review, OneBeacon’s actuaries select indicated reserve levels based on the results of the actuarial methods described previously, which are the primary consideration in determining management’s best estimate of required reserves. However, in making its best estimate, management also considers other qualitative factors that may lead to a difference between held reserves and actuarially recommended levels in the future. Typically, these factors exist when management and OneBeacon’s actuaries conclude that there is insufficient historical reported and paid loss information or that trends included in the historical reported and paid loss information are unlikely to repeat in the future. Such factors include, among others, recent entry into new markets or new products, improvements in the claims department that are expected to lessen future ultimate loss costs and legal and regulatory developments. At December 31, 2012 and 2011, total carried reserves, including reserves that are presented as liabilities held for sale in the December 31, 2012 balance sheet related to the Runoff Business, were 6% and 10%, respectively, above the actuarial point estimate.

For loss and allocated LAE reserves, excluding A&E, the key assumption as of December 31, 2012 was that the impact of the various reserving factors, as described below, on future paid losses would be similar to the impact of those factors on the historical loss data with the exception of severity trends, which have been relatively stable over the relevant historical period. The actuarial methods used would project losses assuming continued stability in severity trends. Management has considered future increases in loss severity trends, including the impact of inflation, in making its reserve selections.
The major causes of material uncertainty (“reserving factors”) generally will vary for each product line, as well as for each separately analyzed component of the product line. The following section details reserving factors by product line. There could be other reserving factors that may impact ultimate claim costs. Each reserving factor presented will have a different impact on estimated reserves. Also, reserving factors can have offsetting or compounding effects on estimated reserves. For example, in workers compensation, the use of expensive medical procedures that result in medical cost inflation may enable workers to return to work faster, thereby lowering indemnity costs. Thus, in almost all cases, it is impossible to discretely measure the effect of a single reserving factor and construct a meaningful sensitivity expectation. Actual results will likely vary from expectations for each of these assumptions, resulting in an ultimate claim liability that is different from that being estimated currently.


76


Workers compensation
Workers compensation covers an employer’s liability for injuries, disability or death of employees, without regard to fault, as prescribed by state workers compensation law and other statutes. Workers compensation is generally considered a long tail coverage, as it takes a relatively long period of time to finalize claims from a given accident year. While certain payments such as initial medical treatment or temporary wage replacement for the injured worker are made quickly, some other payments are made over the course of several years, such as awards for permanent partial injuries. In addition, some payments can run as long as the injured worker’s life, such as permanent disability benefits and ongoing medical care. Despite the possibility of long payment tails, the reporting lags are generally short, settlements are generally not complex, and most of the liability can be considered high frequency with moderate severity. The largest reserve risk generally comes from the low frequency, high severity claims providing lifetime coverage for medical expense arising from a worker’s injury.
Examples of common reserving factors that can change and, thus, affect the estimated workers compensation reserves include:

General workers compensation reserving factors
Mortality trends of injured workers with lifetime benefits and medical treatment or dependents entitled to survivor benefits
Degree of cost shifting between workers compensation and health insurance
Changes in claim handling philosophies (e.g., case reserving standards)
 
Indemnity reserving factors 
Time required to recover from the injury
Degree of available transitional jobs
Degree of legal involvement
Changes in the interpretations and processes of various workers compensation bureaus’ oversight of claims
Future wage inflation for states that index benefits
Changes in the administrative policies of second injury funds
Re-marriage rate for spouse in instances of death
 
Medical reserving factors
Changes in the cost of medical treatments, including prescription drugs, and underlying fee schedules
Frequency of visits to health providers
Number of medical procedures given during visits to health providers
Types of health providers used
Type of medical treatments received
Use of preferred provider networks and other medical cost containment practices
Availability of new medical processes and equipment
Changes in the use of pharmaceutical drugs
Degree of patient responsiveness to treatment

Changes in underwriting standards

Multiple peril
Multiple peril represents a package policy sold to insureds or to members of trade associations or other groups that include general liability and property insurance. General liability covers businesses for any liability resulting from bodily injury and property damage arising from general business operations, accidents on a premises and the products manufactured or sold. Property covers losses to a business’ premises, inventory and equipment as a result of weather, fire, theft and other causes. Because commercial multiple peril provides a combination of property and liability coverage typically for small businesses, it includes both short and long tail coverages. For property coverage, it generally takes a relatively short period of time to close claims, while for the other coverages, generally for the liability coverages, it takes a longer period of time to close claims. The reserving risk for this line is dominated by the liability coverage portion of this product, except occasionally in the event of catastrophic or large single losses.

77


Multiple peril liability reserves here are generally analyzed as two components: bodily injury and property damage. Bodily injury payments reimburse the claimant for damages pertaining to physical injury as a result of the policyholder’s legal obligation arising from non-intentional acts such as negligence, subject to the insurance policy provisions. In some cases the damages can include future wage loss (which is a function of future earnings power and wage inflation) and future medical treatment costs. Property damage payments result from damages to the claimant’s private property arising from the policyholder’s legal obligation for non-intentional acts. In most cases, property damage losses are a function of costs as of the loss date, or soon thereafter. Defense costs are also a part of the insured costs covered by liability policies and can be significant, sometimes greater than the cost of the actual paid claims, though for some products this risk is mitigated by policy language such that the insured portion of defense costs erodes the amount of policy limit available to pay the claim.
Multiple peril liability is generally considered a long tail line, as it takes a relatively long period of time to finalize and settle claims from a given accident year. The speed of claim reporting and claim settlement is a function of the specific coverage provided and the jurisdiction, among other factors. There are numerous components underlying the multiple peril liability product line. Some of these have relatively moderate payment patterns (with most of the claims for a given accident year closed within 5 to 7 years), while others can have extreme lags in both reporting and payment of claims (e.g., a reporting lag of a decade for “construction defect” claims).
Examples of common reserving factors that can change and, thus, affect the estimated multiple peril liability reserves include:

Multiple peril liability reserving factors
Changes in claim handling philosophies (e.g., case reserving standards)
Changes in policy provisions or court interpretations of such provisions
New theories of liability
Trends in jury awards
Changes in the propensity to sue, in general with specificity to particular issues
Changes in statutes of limitations
Changes in the underlying court system
Distortions from losses resulting from large single accounts or single issues
Changes in tort law
Shifts in lawsuit mix between federal and state courts
Changes in settlement patterns

Multiple peril liability book of business reserving factors 
Changes in policy provisions (e.g., deductibles, policy limits, or endorsements)
Changes in underwriting standards
Product mix (e.g., size of account, industries insured, or jurisdiction mix)

Commercial automobile liability
The commercial automobile product line is a mix of property and liability coverages and, therefore, includes both short and long tail coverages. The payments that are made quickly typically pertain to auto physical damage (property) claims and property damage (liability) claims. The payments that take longer to finalize and are more difficult to estimate relate to bodily injury claims. Commercial automobile reserves are typically analyzed in two components; liability and collision/comprehensive claims. This second component has minimum reserve risk and fast payouts and, accordingly, separate reserving factors are not presented. The liability component includes claims for both bodily injury and property damage. In general, claim reporting lags are minor, claim complexity is not a major issue, and the line is viewed as high frequency, low to moderate severity.

78


Examples of common reserving factors that can change and, thus, affect the estimated commercial automobile liability reserves include:

Bodily injury and property damage liability reserving factors
Trends in jury awards
Changes in the underlying court system
Changes in case law
Litigation trends
Frequency of claims with payment capped by policy limits
Change in average severity of accidents, or proportion of severe accidents
Subrogation opportunities
Changes in claim handling philosophies (e.g., case reserving standards)
Frequency of visits to health providers
Number of medical procedures given during visits to health providers
Types of health providers used
Types of medical treatments received
Changes in cost of medical treatments
Degree of patient responsiveness to treatment
 
Commercial automobile liability book of business reserving factors
Changes in policy provisions (e.g., deductibles, policy limits, or endorsements)
Changes in mix of insured vehicles (e.g., long-haul trucks versus local and smaller vehicles, or fleet risks versus non-fleet risks)
Changes in underwriting standards

General liability
See the above discussions under the liability product lines with regard to reserving factors for multiple peril, which are similar to the reserving factors used for general liability.

OneBeacon Loss and LAE Development - Ongoing Business

Loss and LAE development—2012
During 2012, OneBeacon experienced $7 million of net favorable loss and LAE reserve development on prior accident year reserves. The favorable reserve development was primarily from workers' compensation, multiple peril liability and general liability lines. This favorable development was offset somewhat by unexpected adverse development on excess property claims.

Loss and LAE development—2011
During 2011, OneBeacon experienced $30 million of net favorable loss and LAE reserve development on prior accident year loss reserves. The favorable loss reserve development was primarily due to lower than expected severity on non-catastrophe losses related to professional liability lines, multiple peril liability lines and other general liability lines.
With respect to the favorable loss reserve development in specialty insurance operations, at December 31, 2010, management had revised its expectations downward for future loss emergence in the professional liability business, which had initially been based on market analysis when this business was initiated in 2002 and 2003. However, during 2011, losses continued to be significantly lower than these revised expectations. As a result, management lowered its selected reserves on the earliest years which affected more recent years as total loss expectations for those years are based in part on prior years’ results. The impact of this revised estimate was a decrease to professional liability reserves of $12 million.
During 2010, management began separately reviewing loss reserves for some business which had been previously managed as a part of OneBeacon’s former commercial lines underwriting unit.  As of December 31, 2010, the reserves for these businesses had been selected based on expected emergence that was based on the historic loss development of former commercial lines underwriting unit.  However, during 2011 the actual emerged experience for these businesses was significantly lower than the expected emergence.  As a result of this favorable emergence, management lowered the loss reserves for these businesses by $14 million during 2011.
In addition to the development described for the lines of business above, OneBeacon also recorded a $4 million net decrease in reserves in other lines of business as a result of its review of loss reserves at December 31, 2011.

Loss and LAE development—2010
In 2010, OneBeacon experienced $36 million of net favorable loss and LAE reserve development on prior accident year loss reserves. The favorable loss reserve development was primarily due to lower than expected severity on non-catastrophe losses related to professional liability lines, multiple peril liability lines and other general liability lines, as well as development on personal lines business. The favorable development also included an $8 million release of commercial catastrophe reserves associated with storms occurring in 2004 and 2005.
Specifically, at December 31, 2009, management had revised its expectations downward with respect to future loss emergence in the professional liability business, which had initially been based on market analysis when this business was initiated in 2002 and 2003. However, during 2010, losses continued to be significantly lower than these revised expectations. As a result, management lowered its selected reserves on the earliest years which affected more recent years as total loss expectations for those years are based in part on prior years’ results. The impact of this revised estimate was a decrease to professional liability reserves of $19 million.
At December 31, 2009, management had recorded $8 million of reserves for certain claims related to catastrophes from accident years 2004 and 2005 related to OneBeacon’s excess property business. During 2010, these claims were resolved for amounts below OneBeacon’s policy coverage therefore the reserves were no longer necessary. In addition to the development described for the lines of business above, management also recorded a $9 million net decrease in IBNR in other lines of business, primarily personal lines, as a result of its review of loss reserves at December 31, 2010.

OneBeacon Loss and LAE Development - Runoff Business

Loss and LAE development—2012
During 2012, OneBeacon experienced $40 million of net unfavorable loss and LAE development related to the Runoff Business primarily driven by case incurred development on claims related to multiple peril liability lines and general liability lines and also the impact of an adverse court ruling in Mississippi regarding a disputed assessment from an involuntary pool for hurricane Katrina claims. In addition, there was a change in the workers' compensation tabular discount rate from 4.5% to 3.5% that resulted in unfavorable loss reserve development of $15 million.

Loss and LAE development—2011
During 2011, OneBeacon experienced $27 million of net unfavorable loss and LAE reserve development on prior accident year loss reserves relating to the Runoff Business. The net unfavorable loss reserve development resulted from a detailed review of runoff expenses, principally unallocated loss adjustment expenses (“ULAE”), completed during the fourth quarter of 2011. Specifically, OneBeacon completed a detailed review of loss and defense and cost containment expenses (allocated LAE or “ALAE”) and other adjusting expenses (ULAE) during the fourth quarter of 2011. The analysis considered costs, based on current non-staff expenses and staffing projections for the runoff business, as OneBeacon continued efforts to segregate its claims operations between ongoing claims and runoff claims. The analysis also factored in the revised definition of runoff claims to include the non-specialty commercial lines business that was exited via the renewal rights agreement sale beginning with January 1, 2010 effective dates.

Loss and LAE development—2010
During 2010, OneBeacon experienced $23 million of net favorable loss and LAE reserve development on prior accident year loss reserves relating to the Runoff Business. The net favorable loss reserve development was primarily due to lower than expected severity on multiple peril liability lines and other general liability lines, particularly for accident years 2004 through 2009. As a result of the lower than expected case incurred loss and ALAE, actuarial methods based on case incurred losses produced lower estimated ultimate losses, resulting in lower estimates of required IBNR.

The recorded reserves represent management’s best estimate of unpaid loss and LAE by line of business. OneBeacon uses the results of several different actuarial methods to develop its estimate of ultimate reserves. While OneBeacon has not determined the statistical probability of actual ultimate paid losses falling within the range, OneBeacon believes that it is reasonably likely that actual ultimate paid losses will fall within the ranges noted above because the ranges were developed by using several different generally accepted actuarial methods.
The probability that ultimate losses will fall outside of the ranges of estimates by line of business is higher for each line of business individually than it is for the sum of the estimates for all lines taken together due to the effects of diversification. The diversification effects result from the fact that losses across OneBeacon’s different lines of business are not completely correlated. Although OneBeacon believes its reserves are reasonably stated, ultimate losses may deviate, perhaps materially, from the recorded reserve amounts and could be above or below the range of actuarial projections. This is because ranges are developed based on known events as of the valuation date, whereas the ultimate disposition of losses is subject to the outcome of events and circumstances that may be unknown as of the valuation date.

The percentages shown in the following table represent the linear interpolation of where OneBeacon’s recorded loss and LAE reserves, net of reinsurance recoverable on unpaid losses, are within the range of reserve estimates at December 31, 2012 and 2011, where the low end of the range equals zero, the middle of the range equals 50% and the high end of the range equals 100%. The middle of the range (50%) does not necessarily represent the actuarial indication within the range of possible outcomes, provided above. During 2012, OneBeacon modeled the range of reserves for its Ongoing Business at a more refined line of business level than it had previously used; the prior period has been restated to reflect the more refined range.

In selecting its best estimate, management continues to monitor the impact of future increases in inflation, including adverse changes in tort liability. These types of changes could result in deterioration in the loss reserves. During 2012, inflation continued to emerge in the loss data for some lines of business which increased the actuarial indications and related estimated range of outcomes. Since these changes in inflation assumptions are now being partially reflected in the actuarial methods, management does not need to select reserves as high in the range of actuarial indications. This has had some impact on most lines but has a particular impact on general liability - claims made and medical malpractice within both OneBeacon’s Ongoing Business and its Runoff Business. Additionally, as OneBeacon continues to pay down the obligations associated with its Runoff Business, the uncertainty and volatility associated with those reserves is also declining such that carried reserves, which continue to exceed actuarial indications, are expectedly closer to the middle of the range.
Also in 2012, management lowered held reserves in several businesses that had been previously managed as part of OneBeacon’s former commercial lines underwriting group. This development was primarily related to workers compensation and general liability occurrence. This favorable development resulted in recorded reserves being lower in the range as of December 31, 2012 compared to December 31, 2011.
The percentages shown in the following table represent the linear interpolation of where OneBeacon’s recorded loss and LAE reserves on its Ongoing Business, net of reinsurance recoverable on unpaid losses, are within the range of reserves estimates by line of business at December 31, 2012 and 2011. Similar to the preceding table, the low end of the range equals zero, the middle of the range equals 50% and the high end of the range equals 100%.

Sensitivity Analysis
The following discussion includes disclosure of possible variations from current estimates of loss reserves in OneBeacon’s Ongoing Business due to a change in certain key assumptions. Each of the impacts described below is estimated individually, without consideration for any correlation among key assumptions or among lines of business. Therefore, it would be inappropriate to take each of the amounts described below and add them together in an attempt to estimate volatility for OneBeacon’s reserves in total.
It is important to note that the variations discussed are not meant to be a worst-case scenario, and therefore, it is possible that future variations may be more than amounts discussed below.

Workers compensation: Recorded loss and LAE reserves, net of reinsurance recoverable, for Ongoing and Runoff Business workers compensation were $254 million at December 31, 2012. The two most important assumptions for workers compensation reserves are loss development factors and loss cost trends, particularly medical cost inflation. Loss development patterns are dependent on medical cost inflation. Approximately half of the workers compensation net reserves are related to future medical costs. Across the entire reserve base, a 0.5 point change in calendar year medical inflation would have changed the estimated net reserve by approximately $46 million at December 31, 2012, in either direction.
 
Professional liability:  Recorded loss and LAE reserves, net of reinsurance recoverable, for professional liability were $410 million across all lines at December 31, 2012. A key assumption for professional liability is the implicit loss cost trend, particularly the severity inflation trend component of loss costs. Across the entire reserve base, a 5.0 point change in assumed annual severity would have changed the estimated net reserve by approximately $68 million at December 31, 2012, in either direction.

Multiple peril liability: Recorded loss and LAE reserves for the Ongoing and Runoff Businesses, net of reinsurance recoverable, excluding that provided under the GRC Cover, for multiple peril were $142 million at December 31, 2012. Reported loss development patterns are a key assumption for this line of business, particularly for more mature accident years. Historically, assumptions on reported loss development patterns have been impacted by, among other things, emergence of new types of claims (e.g. construction defect claims) or a shift in the mixture between smaller, more routine claims and larger, more complex claims. If case reserve adequacy for multiple peril claims changed by 10.0 points this would have changed the estimated net reserve by approximately $14 million at December 31, 2012, in either direction.

A&E Reserves
OneBeacon’s reserves include provisions made for claims that assert damages from A&E related exposures. Substantially all of these reserves have been reclassified to liabilities held for sale as of December 31, 2012, as they relate to the Runoff Business. Asbestos claims relate primarily to injuries asserted by those who allegedly came in contact with asbestos or products containing asbestos. Environmental claims relate primarily to pollution and related clean-up cost obligations, particularly as mandated by federal and state environmental protection agencies. In addition to the factors described above regarding the reserving process, OneBeacon estimates its A&E reserves based upon, among other factors, facts surrounding reported cases and exposures to claims, such as policy limits and deductibles, current law, past and projected claim activity and past settlement values for similar claims, as well as analysis of industry studies and events, such as recent settlements and asbestos-related bankruptcies. The cost of administering A&E claims, which is an important factor in estimating loss and LAE reserves, tends to be higher than in the case of non-A&E claims due to the higher legal costs typically associated with A&E claims.
A large portion of OneBeacon’s A&E losses resulted from the operations of the Employers Group, an entity acquired by one of the legacy companies in 1971. These operations, including business of Employers Surplus Lines Insurance Company and Employers Liability Assurance Corporation, provided primary and excess liability insurance for commercial insureds, including Fortune 500-sized accounts, some of whom subsequently experienced claims for A&E losses. OneBeacon stopped writing such coverage in 1984.
OneBeacon’s liabilities for A&E losses from business underwritten in the recent past are substantially limited by the application of exclusionary clauses in the policy language that eliminated coverage for such claims. After 1987 for pollution and 1992 for asbestos, most liability policies contained industry- standard absolute exclusions of such claims. In earlier years, various exclusions were also applied, but the wording of those exclusions was less strict and subsequent court rulings have reduced their effectiveness.

83


OneBeacon also incurred A&E losses via its participation in industry pools and associations. The most significant of these pools was Excess Casualty Reinsurance Association (“ECRA”), which provided excess liability reinsurance to U.S. insurers from 1950 until the early 1980s. ECRA incurred significant liabilities for A&E, of which OneBeacon bears approximately a 4.6% and 4.7% share, or $67 million and $77 million at December 31, 2012 and 2011, respectively, which is fully reflected in OneBeacon’s loss and LAE reserves.
More recently, since the 1990s, OneBeacon has experienced an influx of claims from commercial insureds, including many non-Fortune 500-sized accounts written during the 1970s and 1980s, who are named as defendants in asbestos lawsuits. As a number of large well-known manufacturers of asbestos and asbestos-containing products have gone into bankruptcy, plaintiffs have sought recoveries from peripheral defendants, such as installers, transporters or sellers of such products, or from owners of premises on which the plaintiffs’ exposure to asbestos allegedly occurred. At December 31, 2012, 481 policyholders had asbestos-related claims against OneBeacon. In 2012, 106 new insureds with such peripheral involvement presented asbestos claims under prior OneBeacon policies.
Historically, most asbestos claims have been asserted as product liability claims. Recently, insureds who have exhausted the available products liability limits of their insurance policies have sought from insurers such as OneBeacon payment for asbestos claims under the premises and operations coverage of their liability policies, which may not be subject to similar aggregate limits. OneBeacon expects this trend to continue. However, to date there have been fewer of these premises and operations coverage claims than product liability coverage claims. This may be due to a variety of factors, including that it may be more difficult for underlying plaintiffs to establish losses as stemming from premises and operations exposures, which requires proof of the defendant’s negligence, rather than products liability under which strict legal liability applies. Premises and operations claims may vary significantly and policyholders may seek large amounts, although such claims frequently settle for a fraction of the initial alleged amount. Accordingly, there is a great deal of variation in damages awarded for the actual injuries. As of December 31, 2012, there were approximately 379 active claims by insureds against OneBeacon without product liability coverage asserting operations or premises coverage, which may not be subject to aggregate limits under the policies.
OneBeacon has a reinsurance contract with NICO under which OneBeacon is entitled to recover from NICO up to $2.5 billion in the future for asbestos claims arising from business written by OneBeacon in 1992 and prior, environmental claims arising from business written by OneBeacon in 1987 and prior, and certain other exposures. Under the terms of the NICO Cover, NICO receives the economic benefit of reinsurance recoverables from certain of OneBeacon’s third-party reinsurers in existence at the time the NICO Cover was executed (“Third-Party Recoverables”). As a result, the Third-Party Recoverables serve to protect the $2.5 billion limit of NICO coverage for the benefit of OneBeacon. Any amounts uncollectible from third-party reinsurers due to dispute or the reinsurers’ financial inability to pay are covered by NICO under its agreement with OneBeacon. Third-Party Recoverables are typically for the amount of loss in excess of a stated level each year. Of claim payments from 2000 through 2012, approximately 47% of asbestos and environmental losses have been recovered under the historical third-party reinsurance.
During 2011, OneBeacon completed a study of its legacy A&E exposures. Reasonable estimates of potential adverse scenarios continue to be within the $2.5 billion reinsurance cover issued by NICO. Based on the results of the study, OneBeacon increased the point estimate of incurred losses ceded to NICO from $2.2 billion to $2.3 billion, an increase of $122 million for asbestos, environmental and other mass tort exposures, net of underlying reinsurance. Due to the NICO Cover, there was no impact to income or equity from the change in the estimate.
As part of its previously described actuarial review process, OneBeacon reviews A&E activity each quarter and compares that activity to what was assumed in the most recently completed study. As of December 31, 2012, OneBeacon noted no change in the range of reasonable outcomes around its best estimate described above.
As noted above, OneBeacon has ceded estimated incurred losses of approximately $2.3 billion to the NICO Cover at December 31, 2012. Since entering into the NICO Cover, approximately 9% of the $2.3 billion of utilized coverage relates to uncollectible Third Party Recoverables and settlements on Third Party Recoverables through December 31, 2012. Net losses paid totaled approximately $1.5 billion as of December 31, 2012. To the extent that actual experience differs from OneBeacon’s estimate of incurred A&E losses and Third Party Recoverables, future losses could exceed the $198 million of protection remaining under the NICO Cover.

84


OneBeacon’s reserves for A&E losses, net of Third-Party Recoverables but prior to NICO recoveries, were $0.7 billion at December 31, 2012. An industry benchmark of reserve adequacy is the “survival ratio”, computed as a company’s reserves divided by its historical average yearly loss payments. This ratio indicates approximately how many more years of payments the reserves can support, assuming future yearly payments are equal to historical levels. OneBeacon’s survival ratio was 10.4 years at December 31, 2012. This was computed as the ratio of A&E reserves, net of Third-Party Recoverables prior to the NICO Cover of $0.7 billion plus the remaining unused portion of the NICO Cover of $198 million, to the average A&E loss payments over the three-year period ended December 31, 2012, net of Third-Party Recoverables. OneBeacon’s survival ratio was 13.3 years at December 31, 2011. OneBeacon believes that as a result of the NICO Cover and its historical third-party reinsurance programs, OneBeacon should not experience material financial loss from A&E exposures under current coverage interpretations and that its survival ratio compares favorably to industry survival ratios. However, the survival ratio is a simplistic measure estimating the number of years it would be before the current ending loss reserves for these claims would be paid using recent annual average payments subject to adjustments for unusual items. Many factors, such as aggressive settlement procedures, mix of business and coverage provided, have a significant effect on the amount of A&E reserves and payments and the resultant survival ratio. Thus, caution should be exercised in attempting to determine reserve adequacy for these claims based simply on this survival ratio.
OneBeacon’s reserves for A&E losses at December 31, 2012 represent management’s best estimate of its ultimate liability based on information currently available. However, significant uncertainties, including but not limited to case law developments, medical and clean-up cost increases and industry settlement practices, limit management’s ability to accurately estimate ultimate liability and OneBeacon may be subject to A&E losses beyond currently estimated amounts. In addition, OneBeacon remains liable for risks reinsured in the event that a reinsurer does not honor its obligations under reinsurance contracts. See Note 3—“Reserves for Unpaid Loss and LAE—Asbestos and environmental loss and LAE reserve activity” of the accompanying historical consolidated financial statements for more information regarding its A&E reserves.

Sirius Group

The estimation of net reinsurance loss and LAE reserves is subject to the same risk as the estimation of insurance loss and LAE reserves. In addition to those risk factors which give rise to inherent uncertainties in establishing insurance loss and LAE reserves, the inherent uncertainties of estimating such reserves are even greater for the reinsurer, due primarily to: (1) the claim-tail for reinsurers being further extended because claims are first reported to the original primary insurance company and then through one or more intermediaries or reinsurers, (2) the diversity of loss development patterns among different types of reinsurance treaties or facultative contracts, (3) the necessary reliance on the ceding companies for information regarding reported claims and (4) the differing reserving practices among ceding companies.

Sirius Group’s A&E exposures are principally the result of runoff of businesses acquired in the 1990s.
(2) 
Included in this class are primarily the runoff exposures from various acquisitions.

In order to reduce the potential uncertainty of loss reserve estimation, Sirius Group obtains information from numerous sources to assist in the process. Sirius Group’s underwriting and pricing actuaries devote considerable effort to understanding and analyzing each insured’s operations and loss history during the underwriting of the business, using a combination of insured and industry statistics. Such statistics normally include historical premium and loss data by class of business, individual claim information for larger claims, distributions of insurance limits provided, loss reporting and payment patterns, and rate change history. This analysis is used to project expected loss ratios for each treaty during the upcoming contract period. These expected ultimate loss ratios are aggregated across all treaties and are input directly into the loss reserving process to generate the expected loss ratios that are used to estimate IBNR.
Upon notification of a loss from an insured (typically a ceding company), Sirius Group establishes case reserves, including LAE reserves, based upon Sirius Group’s share of the amount of reserves established by the insured and Sirius Group’s independent evaluation of the loss. In cases where available information indicates that reserves established by a ceding company are inadequate, Sirius Group establishes case reserves or IBNR in excess of its share of the reserves established by the ceding company. Also, in certain instances, Sirius Group may decide not to establish case reserves or IBNR, when the information available indicates that reserves established by ceding companies are not adequately supported. In addition, specific claim information reported by insureds or obtained through claim audits can alert management to emerging trends such as changing legal interpretations of coverage and liability, claims from unexpected sources or classes of business, and significant changes in the frequency or severity of individual claims where customary. Generally, ceding company audits are not customary outside the United States. This information is often used to supplement estimates of IBNR.
Although loss and LAE reserves are initially determined based on underwriting and pricing analyses, Sirius Group regularly reviews the adequacy of its recorded reserves by using a variety of generally accepted actuarial methods, including historical incurred and paid loss development methods. If actual loss activity differs substantially from expectations, an adjustment to recorded reserves may be warranted. As time passes, loss reserve estimates for a given year will rely more on actual loss activity and historical patterns than on initial assumptions based on pricing indications.
Sirius Group’s expected annual loss reporting assumptions are updated at least once a year. Expected loss ratios underlying the current accident year are updated quarterly, to reflect new business that is underwritten by the company.

As mentioned above, there can be a considerable time lag from the time a claim is reported to a ceding company to the time it is reported to the reinsurer. The lag can be several years in some cases. This lag can be due to a number of reasons, including the time it takes to investigate a claim, delays associated with the litigation process, the deterioration in a claimant’s physical condition many years after an accident occurs, etc. In its loss reserving process, Sirius Group assumes that such lags are predictable, on average, over time and therefore the lags are contemplated in the loss reporting patterns used in its actuarial projection methods. This means that, as a reinsurer, Sirius Group must rely on such actuarial estimates for a longer period of time after reserves are first estimated than does a primary insurance company.
Backlogs in the recording of assumed reinsurance can also complicate the accuracy of loss reserve estimation. As of December 31, 2012, there were no significant backlogs related to the processing of assumed reinsurance information at Sirius Group.
Sirius Group relies heavily on information reported by ceding companies, as discussed above. In order to determine the accuracy and completeness of such information, Sirius Group underwriters, actuaries, and claims personnel perform audits of certain ceding companies where customary. Generally, ceding company audits are not customary outside the United States. In such cases, Sirius Group reviews information from ceding companies for unusual or unexpected results. Any material findings are discussed with the ceding companies. Sirius Group sometimes encounters situations where it is determined that a claim presentation from a ceding company is not in accordance with contract terms.  Most situations are resolved amicably and without the need for litigation or arbitration. However, in the infrequent situations where a resolution is not possible, Sirius Group will vigorously defend its position in such disputes.
Sirius Group also obtains reinsurance whereby another reinsurer contractually agrees to indemnify Sirius Group for all or a portion of the risks underwritten by Sirius Group. Such arrangements, where one reinsurer provides reinsurance to another reinsurer, are usually referred to as “retrocessional reinsurance” arrangements. Sirius Group establishes estimates of amounts recoverable from retrocessional reinsurance in a manner consistent with the loss and LAE liability associated with reinsurance contracts offered to its customers, net of an allowance for uncollectible amounts, if any. Net reinsurance loss reserves represent loss and LAE reserves reduced by ceded reinsurance recoverable on unpaid losses.
In 2012, Sirius Group had net favorable loss reserve development of $34 million. The major reductions in loss reserve estimates were recognized in casualty runoff ($32 million), property ($28 million), marine/energy ($12 million), trade credit ($7 million) and aviation/space ($5 million) lines, partially offset by a $46 million increase in asbestos loss reserves and a $4 million increase in accident and health. In 2011, Sirius Group had net favorable loss reserve development of $47 million, primarily attributable to $41 million of favorable development on property lines, including $13 million of loss reserve reductions for the 2010 Chile earthquake, partially offset by asbestos and environmental increases of $12 million.  In 2010, Sirius Group had net favorable loss reserve development of $57 million, primarily related to short-tailed lines, such as property, accident and health, and marine, from recent underwriting years. Included in the $57 million favorable loss reserve development was the recognition of $16 million in deferred gains from a retrocessional reinsurance contract that incepted in 2000 and was fully collected in 2010.
The actuarial methods described above are used to calculate a point estimate of loss and LAE reserves for each company within Sirius Group. These point estimates are then aggregated to produce an actuarial point estimate for the entire segment. Once a point estimate is established, Sirius Group’s actuaries estimate loss reserve ranges to measure the sensitivity of the actuarial assumptions used to set the point estimates. These ranges are calculated from historical variations in loss ratios, payment and reporting patterns by class and type of business.
The actuarial analysis is a primary consideration for management in determining its best estimate of loss and LAE reserves. In making its best estimate, management also considers other qualitative factors that may lead to a difference between its best estimate of loss and LAE reserves and the actuarial point estimate. Typically, these factors exist when management and the company’s actuaries conclude that there is insufficient historical incurred and paid loss information or that trends included in the historical incurred and paid loss information are unlikely to repeat in the future. These factors may include, among others, changes in the techniques used to assess underwriting risk, more accurate and detailed levels of data submitted with reinsurance applications, the uncertainty of the current reinsurance pricing environment, the level of inflation in loss costs, changes in ceding company reserving practices, and legal and regulatory developments. At December 31, 2012 and 2011, total carried net reserves were 2.4% and 2.7% above the actuarial point estimate, respectively.

The probability that ultimate losses will fall outside of the range of estimates by class of business is higher for each class of business individually than it is for the sum of the estimates for all classes taken together due to the effects of diversification. Management believes that it is reasonably likely that actual ultimate losses will fall within the total range noted above because the ranges were developed by using generally accepted actuarial methods supplemented with input of underwriting and claims staff. However, due to the inherent uncertainty, ultimate losses may deviate, perhaps materially, from the recorded reserve amounts and could be above or below the range of actuarial projections.

Sirius Group A&E Reserves
Sirius Group's A&E exposure is primarily from reinsurance contracts written between 1974 through 1985 by acquired companies, mainly MONY Reinsurance Company and Christiania General Insurance Company. The exposures are mostly higher layer excess of loss treaty and facultative coverages with relatively low limits exposed for each claim. In 2012, Sirius Group increased its net A&E exposure through two incoming runoff portfolios acquired by White Mountains Solutions. These acquisitions added $11 million in net asbestos reserves and $1 million in net environmental reserves.
The acquisition of companies having modest portfolios of A&E exposure has been typical of several prior White Mountains Solutions transactions and is likely to be an element of at least some future acquisitions. However, the acquisitions of new A&E liabilities is undertaken only after careful due diligence and utilizing conservative reserving assumptions in relation to industry benchmarks. In the case of those portfolios acquired during 2012, the exposures arise almost entirely from old assumed reinsurance contracts having small limits of liability.
In addition to the $11 million increase in asbestos reserves from the two incoming portfolios acquired by White Mountains Solutions mentioned above, Sirius Group recorded $46 million and $10 million of asbestos-related incurred losses and LAE on its already existing asbestos reserves in 2012 and 2011, respectively.  In the first six months of 2012, Sirius Group increased net asbestos reserves by $12 million in response to its quarterly monitoring of newly reported claims. Based on the monitoring trends noted in the first six months 2012, Sirius Group conducted an in-depth analysis of its asbestos exposure, which was completed in third quarter. The main focus of the analysis was on the internal claims analysis of all treaty and facultative contracts likely to have asbestos exposure.  An external expert with extensive asbestos claims experience was utilized to enhance the review.  This analysis entailed examining total expected asbestos losses and LAE from a variety of information sources, including previous asbestos studies, reported client data and external benchmarking scenarios.  The analysis resulted in a net asbestos loss reserve increase of $33 million recognized in third quarter. An additional $2 million of asbestos losses were recognized in fourth quarter 2012. The 2011 incurred losses were primarily the result of management's monitoring of a variety of metrics including: actual paid and reported claims activity; net survival ratios; peer comparisons; and industry benchmarks.
Offsetting the $1 million increase in environmental reserves mentioned above, Sirius Group recorded a decrease of $1 million in 2012 of environmental-related losses on its already existing reserves in 2012. In 2011, Sirius Group recorded $2 million of environmental losses.

Sirius Group’s net reserves for A&E losses were $189 million and $163 million at December 31, 2012 and 2011, respectively. Sirius Group’s A&E three-year net loss paid survival ratio was approximately 9.0 years and 11.1 years at December 31, 2012 and 2011. The decrease in the paid survival ratio in 2012 was driven by an unusually high net paid loss of $9 million made in first quarter 2012 to commute one of Sirius Group's top five asbestos exposures.

Sirius Group A&E Claims Activity
 Sirius Group has a specialized unit that handles claims relating to A&E exposures. The issues presented by these types of claims require expertise and an awareness of the various trends and developments in relevant jurisdictions. Generally, Sirius Group sets up claim files for each reported claim by cedent for each individual insured. In many instances, a single claim notification from a cedent could involve several years and layers of coverage resulting in a file being set up for each involvement. Precautionary claim notices are submitted by the ceding companies in order to preserve their right to pursue coverage under the reinsurance contract. Such notices do not contain an incurred loss amount. Accordingly, an open claim file is not established. As of December 31, 2012, Sirius Group had 1,859 open claim files for asbestos and 281 open claim files for environmental exposures.

The costs associated with administering the underlying A&E claims by Sirius Group’s clients tend to be higher than non-A&E claims due to generally higher legal costs incurred by ceding companies in connection with A&E claims ceded to Sirius Group under the reinsurance contracts.

2. Fair Value Measurements

General
White Mountains measures certain assets and liabilities at estimated fair value in its consolidated financial statements, with changes therein recognized in current period earnings. In addition, White Mountains discloses estimated fair value for certain liabilities measured at historical or amortized cost. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants (an exit price) at a particular measurement date. Fair value measurements are categorized into a hierarchy that distinguishes between inputs based on market data from independent sources (“observable inputs”) and a reporting entity’s internal assumptions based upon the best information available when external market data is limited or unavailable (“unobservable inputs”).  Quoted prices in active markets for identical assets have the highest priority (“Level 1”), followed by observable inputs other than quoted prices including prices for similar but not identical assets or liabilities (“Level 2”), and unobservable inputs, including the reporting entity’s estimates of the assumptions that market participants would use, having the lowest priority (“Level 3”).
Assets and liabilities carried at fair value include substantially all of the investment portfolio; derivative instruments, both exchange traded and over the counter instruments; and reinsurance assumed liabilities associated with variable annuity benefit guarantees. Valuation of assets and liabilities measured at fair value require management to make estimates and apply judgment to matters that may carry a significant degree of uncertainty. In determining its estimates of fair value, White Mountains uses a variety of valuation approaches and inputs. Whenever possible, White Mountains estimates fair value using valuation methods that maximize the use of observable prices and other inputs. Where appropriate, assets and liabilities measured at fair value have been adjusted for the effect of counterparty credit risk.


90


Invested Assets
White Mountains’ invested assets that are measured at fair value include fixed maturity securities, common and preferred equity securities, convertible fixed maturity securities and interests in hedge funds and private equity funds.
Where available, the estimated fair value of investments is based upon quoted prices in active markets. In circumstances where quoted prices are unavailable, White Mountains uses fair value estimates based upon other observable inputs including matrix pricing, benchmark interest rates, market comparables, and other relevant inputs. Where observable inputs are not available, the estimated fair value is based upon internal pricing models using assumptions that include inputs that may not be observable in the marketplace but which reflect management’s best judgment given the circumstances and consistent with what other market participants would use when pricing such instruments.
As of December 31, 2012, approximately 95.0% of the investment portfolio recorded at fair value was priced based upon quoted market prices or other observable inputs. Investments valued using Level 1 inputs include fixed maturities, primarily investments in U.S. Treasuries, common equities and short-term investments, which include U.S. Treasury Bills. Investments valued using Level 2 inputs comprise fixed maturities including corporate debt, state and other governmental debt, convertible fixed maturity securities and mortgage and asset-backed securities. Fair value estimates for investments that trade infrequently and have few or no observable market prices are classified as Level 3 measurements. Level 3 fair value estimates based upon unobservable inputs include White Mountains’ investments in hedge funds and private equity funds, as well as investments in certain debt securities, including asset-backed securities, where quoted market prices are unavailable. White Mountains uses brokers and outside pricing services to assist in determining fair values. For investments in active markets, White Mountains uses the quoted market prices provided by outside pricing services to determine fair value. The outside pricing services used by White Mountains have indicated that if no observable inputs are available for a security, they will not provide a price. In those circumstances, White Mountains estimates the fair value using industry standard pricing models and observable inputs such as benchmark interest rates, matrix pricing, market comparables, broker quotes, issuer spreads, bids, offers, credit rating prepayment speeds and other relevant inputs. White Mountains performs procedures to validate the market prices obtained from the outside pricing sources. Such procedures, which cover substantially all of its fixed maturity investments include, but are not limited to, evaluation of model pricing methodologies and review of the pricing services’ quality control processes and procedures on at least an annual basis, comparison of market prices to prices obtained from a different independent pricing vendors on at least a semi-annual basis, monthly analytical reviews of certain prices, and review of assumptions utilized by the pricing service for selected measurements on an ad hoc basis throughout the year. White Mountains also performs back-testing of selected sales activity to determine whether there are any significant differences between the market price used to value the security prior to sale and the actual sale price on an ad-hoc basis throughout the year. Prices provided by the pricing services that vary by more than 5% and $1 million from the expected price based on these procedures are considered outliers. In circumstances where the results of White Mountains’ review process do not appear to support the market price provided by the pricing services, White Mountains challenges the price.  During the past year, approximately fifteen securities fell outside White Mountains’ expected results, thereby triggering the challenge with the pricing service. If White Mountains cannot gain satisfactory evidence to support the challenged price, it relies upon its own pricing methodologies to estimate the fair value of the security in question. The fair values of such securities are considered to be Level 3 measurements.

White Mountains uses quoted market prices where available as the inputs to estimate fair value for its investments in active markets. Such measurements are considered to be either Level 1 or Level 2 measurements, depending on whether the quoted market price inputs are for identical securities (Level 1) or similar securities (Level 2). Level 3 measurements for fixed maturities at December 31, 2012 comprise securities for which the estimated fair value has not been determined based upon quoted market price inputs for identical or similar securities.

Fair Value Measurements — transfers between levels
 During 2012, two fixed maturity securities classified as Level 3 measurements in the prior period were recategorized as Level 2 measurements because quoted market prices for similar securities that were considered reliable and could be validated against an alternative source were available at December 31, 2012.  These measurements comprise “Transfers out” of Level 3 and “Transfers in” to Level 2 of $61.8 million for the period ended December 31, 2012. For the year-ended December 31, 2012, “Transfers out” of Level 2 and “Transfers in” to Level 3 fixed maturity investments of $22.1 million consists of one asset-backed security for which the estimated fair value was determined using a single broker quote.
At December 31, 2011, ten fixed maturity securities which had been classified as Level 3 measurements at January 1, 2011 were recategorized as Level 2 measurements because quoted market prices for similar securities that were considered reliable and could be validated against an alternative source were available at December 31, 2011. These measurements comprise “Transfers out” of Level 3 and “Transfers in” to Level 2 of $269.2 million for the period ended December 31, 2011.  One security that was classified as a Level 2 investment at January 1, 2011 was priced with unobservable inputs and represents “Transfers in” of $18.2 million in Level 3 investments.  The fair value of this security was estimated using industry standard pricing models, in which management selected inputs using its best judgment.  The pricing models used by White Mountains use the same valuation methodology for all Level 3 measurements for fixed maturities. The security is considered to be Level 3 because the measurements are not directly observable. At December 31, 2011, the estimated fair value for this security determined using the industry standard pricing models was $1.6 million less than the estimated fair value based upon quoted prices provided by a third party pricing vendor.
The following table summarizes the amount of total gains (losses) included in earnings attributable to unrealized investment gains (losses) for Level 3 investments for years ended December 31, 2012, 2011, and 2010:

Symetra Warrants
White Mountains holds warrants to acquire common shares of Symetra. The warrants are recorded at fair value. White Mountains uses a Black-Scholes valuation model to determine the fair value of the Symetra warrants. The major assumptions used in valuing the Symetra warrants at December 31, 2012 were a risk free rate of 0.21%, volatility of 38.9%, an expected life of 1.6 years, a strike price of $11.49 per share and a share price of $12.98 per share. The major assumptions used in valuing the Symetra warrants at December 31, 2011 were a risk free rate of 0.31%, volatility of 36.0%, an expected life of 2.6 years, a strike price of $11.49 per share and a share price of $9.07 per share.  The inputs used in the valuation model are observable inputs. However, since a quoted market price is not available for the warrants themselves, they are categorized as a Level 2 measurement.

Other Long-Term Investments
Other long-term investments accounted for at fair value at December 31, 2012 consist of $115 million in hedge funds and $125 million in private equity funds.  At December 31, 2012, White Mountains held investments in 16 hedge funds and 38 private equity funds.  The largest investment in a single fund was $16.0 million and $27.4 million at December 31, 2012 and 2011.
The fair value of White Mountains’ investments in hedge funds and private equity funds is based upon White Mountains’ proportionate interest in the underlying fund’s net asset value, which is deemed to approximate fair value.  White Mountains employs a number of procedures to assess the reasonableness of the fair value measurements for its other long-term investments including obtaining and reviewing each fund’s audited financial statements and discussing each fund’s pricing with the fund’s manager.  However, since the fund managers do not provide sufficient information to independently evaluate the pricing inputs and methods for each underlying investment, the inputs are considered to be unobservable.  Accordingly, the fair values of White Mountains’ investments in hedge funds and private equity funds have been classified as Level 3.
In circumstances where the underlying investments are publicly traded, such as the investments made by hedge funds, the fund manager uses current market prices to determine fair value. In circumstances where the underlying investments are not publicly traded, such as the investments made by private equity funds, the private equity fund managers generally consider the need for a liquidity discount on each of the underlying investments when determining the fund’s net asset value.  In circumstances where White Mountains’ portion of a fund’s net asset value is deemed to differ from fair value due to illiquidity or other factors associated with White Mountains’ investment in the fund, the net asset value is adjusted accordingly.  At December 31, 2012, there were no circumstances where illiquidity or other factors required an adjustment to the net asset value related to any of its investments in hedge funds or private equity funds.

Sensitivity analysis of likely returns on hedge fund and private equity fund investments
White Mountains’ investment portfolio includes investments in hedge funds and private equity funds. At December 31, 2012, the value of investments in hedge funds and in private equity funds was $115 million and $125 million, respectively.  The underlying investments are typically publicly traded and private common equity investments, and, as such, are subject to market risks that are similar to White Mountains’ common equity securities. The following illustrates the estimated effect on December 31, 2012 fair value resulting from a 10% change and a 30% change in market value:

Variable Annuity Reinsurance Liabilities
White Mountains has entered into agreements to reinsure death and living benefit guarantees associated with certain variable annuities in Japan. White Mountains carries the benefit guarantees at fair value. The fair value of the guarantees is estimated using actuarial and capital market assumptions related to the projected discounted cash flows over the term of the reinsurance agreement. The valuation uses assumptions about surrenders rates, market volatilities and other factors, and includes a risk margin which represents the additional compensation a market participant would require to assume the risks related to the business. The selection of surrender rates, market volatility assumptions, risk margins and other factors require the use of significant management judgment. Assumptions regarding future policyholder behavior, including surrender and lapse rates, are generally unobservable inputs and significantly impact the fair value estimate. Market conditions including, but not limited to, changes in interest rates, equity indices, market volatility and foreign currency exchange rates as well as variations in actuarial assumptions regarding policyholder behavior may result in significant fluctuations in the fair value of the liabilities associated with these guarantees that could materially affect results of operations. All of White Mountains' variable annuity reinsurance liabilities ($442 million) were classified as Level 3 measurements at December 31, 2012.
Generally, the liabilities associated with these guarantees increase with declines in the equity markets, interest rates and currencies against the Japanese yen, as well as with increases in market volatilities. In 2008, particularly in the fourth quarter, as a result of worldwide declines in equity markets, interest rates and the strengthening of the Japanese yen, the underlying investment accounts declined substantially and have stayed low. The collective account values were approximately 87% and 78% of the guarantee value at December 31, 2012 and December 31, 2011. The liability is also affected by annuitant related behavioral and actuarial assumptions, including surrender and mortality rates. WM Life Re lowered its projected surrender rates in 2011 and 2010 to reflect the behavior observed during the turbulent markets experienced throughout those years.
WM Life Re uses derivative instruments, including put options, interest rate swaps, total return swaps on bond and equity indices and forwards and futures contracts on major equity indices, currency pairs and government bonds, to mitigate the risks associated with changes in the fair value of the reinsured variable annuity guarantees. The types of inputs used to estimate the fair value of these derivative instruments, with the exception of actuarial assumptions regarding policyholder behavior and risk margins, are generally the same as those used to estimate the fair value of the variable annuity liabilities.
As of December 31, 2012, the value of bond funds tracking the WGBI was approximately ¥68 billion ($786 million). By country, the largest exposures, together comprising over 90% of the WGBI, were the United States (42%), France (10%), Germany (9%), the United Kingdom (8%), Italy (9%), Spain (4%), Canada (3%), the Netherlands (3%), and Belgium (3%). Eurozone countries together comprised approximately 41%. To reduce hedging basis risk (i.e., the risk that changes in the WGBI will cause WM Life Re's variable annuity guarantee liabilities to change in value at a different rate than the derivative hedges), in December 2009 WM Life Re entered into a series of total return swap contracts on the performance of the WGBI. As of December 31, 2010, approximately 49% of WM Life Re's WGBI-related liability was hedged with WGBI swaps. Because these swaps were denominated in US dollars, WM Life Re continued to hedge the results into Japanese yen to match the benchmark denominated in Japanese yen. In 2011, driven in large part by instability of Eurozone markets, WM Life Re significantly increased coverage of its WGBI exposure. Because the market for WGBI total return swaps was, and continues to be illiquid, WM Life Re entered into a series of total return swaps on the JP Morgan European Government Bond Index (JPM European GBI). Although the JPM European GBI is not an exact match for the European component of the WGBI, its construction rules and holdings are substantially similar. These swaps are denominated in Japanese yen and, therefore, need not be hedged into Japanese yen. As of December 31, 2012, the total notional amounts of WGBI and JPM European GBI swaps were $75 million and ¥28 billion ($324 million), respectively. At that date, approximately 64% and 96% of the total WGBI and European component of the WGBI, respectively, were hedged with total return swaps. All $75 million notional amount of WGBI swaps matured in January 2013, reducing coverage on the total WGBI by 3% to approximately 61%. The JPM European GBI total return swaps have maturities laddered during 2015 and 2016 to approximate the maturities of the policies reinsured. The residual WGBI exposure is hedged primarily with bond futures.
Under the terms of these swap contracts, WM Life Re receives cash flows based on a fixed return, reset at the beginning of each month based on current LIBOR and is required to pay cash flows based on the performance of the WGBI or JPM European GBI during that month plus a fixed amount.
WM Life Re hedges the remaining WGBI-related liability exposure with the limited types of available derivatives that most closely fit the country and term exposures of the WGBI. Since liability exposures are determined by the performance of the overall account value, including the funds that track the Nomura BPI, TOPIX, and MSCI Kokusai, periodic portfolio rebalancing may be required. At such times and within limits, exchange-traded futures may be used to maintain overall neutral exposure as opposed to entering into new, or unwinding existing, swaps.

As of December 31, 2012, the value of bond funds tracking the Nomura BPI was approximately ¥73 billion ($844 million). In January 2010, because the types and tenors of liquid Japanese bond futures currently available are extremely limited, to more closely track the performance of bond funds tracking the Nomura BPI, WM Life Re entered into its first total return swap contract on the performance of that index. As of December 31, 2012, the total notional amount of Nomura BPI swaps was ¥57 billion ($662 million), covering approximately 90% of WM Life Re's Nomura BPI-related liability exposure. Of these swaps, ¥13 billion ($159 million), which mature between 2015 and 2016, track the government bond component of the index only (approximately 76% of the index), leaving WM Life Re exposed to credit spread risk on the non-government portion. However, WM Life Re was able to temporarily convert these swaps into swaps that track the complete index through August 2013, at which time they will revert back to swaps that track the government bond component only unless WM Life Re is able to roll the conversion for another period of time. The remaining ¥44 billion ($511 million) track the complete index. Of these, one with a notional amount of ¥10 billion ($130 million) matured in January 2013 and was replaced with a swap of equal size maturing January 2014. The remaining swaps on the complete index mature during 2013. WM Life Re will look for opportunities to replace these swaps as they mature; however, the market is extremely illiquid and there is no guaranty that WM Life Re will be able to do so. Under the contracts, WM Life Re receives cash flows based on a fixed return, reset at the beginning of each period (monthly for the complete index swaps and semi-annually for the government bond only swaps) based on current LIBOR and is required to pay cash flows based on the performance of the Nomura BPI during that period plus a fixed amount. Remaining Nomura BPI exposure is hedged with liquid Japanese bond futures and is subject to basis risk relating to the difference between the tenor of the bond futures and the tenor of the assets in the annuity funds covered by WM Life Re’s variable annuity guarantees.
As of December 31, 2012, the value of equity funds tracking the MSCI Kokusai was approximately ¥30 billion ($346 million). To reduce hedging basis risk, in 2011 WM Life Re entered into a series of total return swaps on the MSCI Kokusai, denominated in Japanese yen with maturities laddered during 2015 and 2016 to approximate the maturities of the policies reinsured. As of December 31, 2012, the total notional amount of MSCI Kokusai swaps was ¥14.5 billion ($177 million) and the percent of MSCI Kokusai fund exposure hedged by these swaps was approximately 60%. The remaining 40% of this exposure continues to be hedged with a variety of more liquid instruments, including exchange-traded futures. WM Life Re continues to assess ways to increase its coverage with total return swaps but there is no guaranty that WM Life Re will be able to do so.
During 2009, WM Life Re entered into long term Japanese interest rate swaps, largely replacing its use of short term Japanese Government Bond (“JGB”) futures to hedge its discount rate exposure.  By doing so, WM Life Re better matched the term structure of its discount rate exposure, substantially reduced its exposure to changes in Japanese interest rate swap spreads and significantly reduced the potential costs associated with rolling JGB futures contracts during times of relative market illiquidity.  During December 2012, after the relevant Japanese interest rate swap rates fell to their lowest level in many years, the resulting potential benefit, net of cost, to WM Life Re of maintaining its Japanese interest rate swap hedge portfolio was deemed to be limited. Therefore, the decision was made to unwind or offset these Japanese interest rate swaps. During December 2012, approximately 24% of the notional amount of Japanese interest rate swap contracts was unwound and during January 2013 the remaining 76% was unwound or offset. As of December 31, 2012 and 2011, the notional amount of Japanese interest rate swaps was ¥153 billion ($1.8 billion) and ¥183 billion ($2.4 billion), respectively.
The following table summarizes the estimated financial impact on WM Life Re's derivatives and benefit guarantee liabilities of instantaneous changes in individual market variables as of December 31, 2012, proforma for the unwinding or offsetting of Japanese interest rate swaps in January of 2013. Remaining hedging coverage of Japanese interest rate swap exposure was 12%, primarily from WM Life Re’s put option portfolio. The table below assumes that all other market variables are constant and does not reflect the inter-dependencies between individual variables.

In the unfavorable scenario, Japanese interest rates are decreased 70 bps, Japanese swap spreads are tightened by 25 bps, and foreign bond fund yields are increased 70 bps.  Conversely, in the favorable scenario, Japanese interest rates are increased 70 bps, Japanese swap spreads are widened 25 bps and foreign bond fund yields are decreased 70 bps. Without taking into account the proforma effect of Japanese interest rate swaps that were unwound or offset in January of 2013, the favorable interest rate change scenario results in an increase of the net value of WM Life Re’s derivative assets and variable annuity guarantee liability of $10, while the unfavorable scenario results in a decrease of $1.

White Mountains’ sensitivities for market implied volatilities vary by term. For equity implied volatilities, White Mountains changes implied volatilities by 15%, 13%, 11%, 9%, 7% and 7% for each of the terms to maturity for years one through six, respectively. For foreign currency implied volatilities, White Mountains changes implied volatilities by 6%, 5.5%, 5%, 4.5%, 4% and 4% for each of the terms to maturity for years one through six, respectively.

To test the impact of multiple variables moving simultaneously, WM Life Re performs capital market “shock” testing. Prior to 2009, in performing this testing, WM Life Re had not incorporated basis risk and other hedge underperformance relative to expectations in its models; it had assumed that its hedges would behave as modeled. However, the financial market turmoil of late 2008 and early 2009 demonstrated that, in periods of severe financial market disruption, various aspects of WM Life Re's hedging program may underperform or over-perform. As a result, WM Life Re now also estimates the efficacy of its hedging program in its “shock” testing. Estimated hedge effectiveness is based on actual results during the recent stressed market environment encompassing the fourth quarter of 2008 and the first quarter of 2009. Hedge effectiveness assumptions also incorporate any subsequent changes to the hedging program that were not in place during this stress period. Although this period captures a historically volatile period that included large market movements over short time periods, hedges may be less effective than the current assumptions to the extent future market movements of the magnitude of these “shocks” occur more quickly than during this recent stress period.
The table below summarizes as of December 31, 2012 and 2011, the estimated financial impact of simultaneous market events, as well as December 31, 2012 on a proforma basis, adjusted for the unwinding or offsetting of the remaining Japanese interest rate swaps during January 2013. Unlike the individual sensitivity analysis illustrated above, the analysis in the table below reflects the inter-dependencies between individual variables.

Assumed hedge effectiveness in down and up markets of 93% and 106%, respectively, as of December 31, 2012 and 93% and 107%, respectively, as of December 31, 2011. Hedge effectiveness as of December 31, 2012 has been adjusted for 24% reduction in Japan interest rate swap coverage due to the unwinding of Japanese interest rate swaps at the end of December. Proforma hedge effectiveness as of December 31, 2012 has been adjusted for the unwinding or offsetting of the remaining Japanese interest rate swaps during January 2013. Some Japanese interest rate swap coverage remains primarily through WM Life Re's put option portfolio.

WM Life Re applies shocks to the Japanese interest rates and foreign bond fund yields in opposite directions. In the down market scenario, Japanese interest rates are decreased 70 bps, Japanese interest rate swap spreads are tightened by 25 bps, and foreign bond fund yields are increased 70 bps. The “up market” scenario assumes opposite movements in the same variables. For other variables, the “down market” scenario assumes equity indices decrease 20%, foreign currencies depreciate by 15% against the Japanese yen and implied market volatility increases as described in footnote 3 to the table above.  The “up market” scenario assumes opposite movements in the same variables. Through December 31, 2012, both the up and down scenarios produce an expected net loss due to the convexity of the liability value, coupled with the assumption that the shock scenarios happen instantaneously without adjustment of the hedging portfolio. The proforma 2012 sensitivity analysis up market scenario results in a positive $10 million due to the reduction in the liability from higher discount rates that is no longer offset by losses from the Japanese interest rate swaps that have been unwound. However, this also causes the proforma 2012 down market scenario to be $13 million worse than the down market scenario as of December 31, 2012.
WM Life Re projects future surrender rates by year for policies based on a combination of actual experience and expected policyholder behavior. Actual policyholder behavior, either individually or collectively, may differ from projected behavior as a result of a number of factors such as the level of the account value versus guarantee value and applicable surrender charge, views of the primary insurance company's financial strength and ability to pay the guarantee at maturity, annuitants' need for money in a prolonged recession and time remaining to receive the guarantee at maturity. Policyholder behavior is especially difficult to predict given that WM Life Re's reinsurance contracts are relatively new and the recent financial turmoil is unprecedented for this type of product in the Japanese market. Actual policyholder behavior may differ materially from WM Life Re's projections.
During the third quarter of 2010, WM Life Re lowered the surrender assumptions that it uses to calculate its variable annuity guarantee liability. WM Life Re’s previous assumptions reflected its expectation that surrenders would rise as the surrender charges in the underlying annuities decline. However, the persistent instability in financial and foreign exchange markets has kept surrenders low. The lower surrender assumptions resulted in a $48 million increase in WM Life Re’s variable annuity guarantee liability, but reduced its exposure to adverse changes in surrender rates in the future. During the fourth quarter of 2011, WM Life Re lowered the surrender assumptions again to reflect the somewhat lower surrenders that emerged versus expected in the policy cohort that rolled into policy year seven, resulting in a $7.2 million increase in the variable annuity guaranty liability. No surrender assumption adjustments were required during 2012.

97


As of December 31, 2012, WM Life Re's surrender assumptions vary from 0.1% currently to 3.0% depending on the level of account value versus guarantee value; at the account value levels as of December 31, 2012, the average assumed surrender rate was approximately 0.5% per annum. The potential increase in the fair value of the liability due to a change in current actuarial assumptions is as follows:

The amounts in the table above could increase in the future if the fair value of the variable annuity guarantee liability changes due to factors other than the surrender assumptions (e.g., a decline in the ratio of the annuitants’ aggregate account values to their aggregate guarantee values).
As of December 31, 2011, WM Life Re increased the variable annuity guaranty liability by $6 million to partially reflect a “basis swap” implied by foreign exchange rates which results in lower projected returns (in Japanese yen) for the portion of funds invested in countries outside of Japan. Since the financial crisis in 2008, there has been a break in expected arbitrage free relationships between swap interest rates and foreign exchange rates (in particular, between the U.S. and Japan). This adjustment recognizes that this anomaly of trading values may be more than temporary. The balance of this reserve was $2.2 million as of December 31, 2012.

3. Sirius Group Reinsurance Estimates

There is a time lag from the point when premium and related commission and expense activity is recorded by a ceding company to the point when such information is reported by the ceding company to Sirius Group. This time lag can vary from one to several contractual reporting periods (i.e. quarterly/monthly). This lag is common in the reinsurance business, but slightly longer when a reinsurance intermediary is involved.
As a result of this time lag in reporting, Sirius Group estimates a portion of its written premium and related commissions and expenses. Given the nature of Sirius Group’s business, estimated premium balances, net of related commissions and expenses, comprise a large portion of total premium balances receivable. The estimation process begins by identifying which major accounts have not reported activity at the most recent period end. In general, premium estimates for excess of loss business are based on expected premium income included in the contractual terms. For proportional business, Sirius Group’s estimates are derived from expected premium volume based on contractual terms or ceding company reports and other correspondence and communication with underwriters, intermediaries and ceding companies. Once premium estimates are determined, related commission and expense estimates are derived using contractual terms.
Sirius Group closely monitors its estimation process on a quarterly basis and adjusts its estimates as more information and actual amounts become known. There is no assurance that the amounts estimated by Sirius Group will not deviate from the amounts reported by the ceding company or reinsurance intermediary. Any such deviations are reflected in the results of operations when they become known.

4. Reinsurance Transactions

White Mountains’ insurance and reinsurance subsidiaries purchase reinsurance from time to time to protect their businesses from losses due to exposure aggregation, to manage their operating leverage ratios and to limit ultimate losses arising from catastrophic events. Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured policies. Amounts related to reinsurance contracts are recorded in accordance with ASC 944, “Accounting and Reporting for Reinsurance of Short-Duration and Long-Duration Contracts” (“ASC 944”).
In connection with White Mountains’ acquisition of OneBeacon in 2001, Aviva caused OneBeacon to purchase reinsurance contracts with two reinsurance companies rated “AA+” (Very Strong, the second highest of twenty-one financial strength ratings) by Standard & Poor’s and “A++” (Superior, the highest of sixteen financial strength ratings) by A.M. Best. One is a reinsurance cover with NICO which entitles OneBeacon to recover up to $2.5 billion in ultimate loss and LAE incurred related primarily to claims arising from business written by its predecessor prior to 1992 for asbestos claims and 1987 for environmental claims, respectively. As of December 31, 2012, OneBeacon has ceded estimated incurred losses of approximately $2.3 billion to NICO under the NICO Cover. The other contract is a reinsurance cover with GRC for up to $570 million of additional losses on all claims arising from accident years 2000 and prior. As of December 31, 2012, OneBeacon has ceded estimated incurred losses of $562 million to GRC under the GRC Cover. The NICO Cover and GRC Cover, which were contingent on and occurred contemporaneously with the acquisition of OneBeacon, were put in place in lieu of a seller guarantee of loss and LAE reserves and are therefore accounted for as a seller guarantee under GAAP in accordance with Emerging Issues Task Force Topic No. D 54. NICO and GRC are wholly-owned subsidiaries of Berkshire. All of these balances relate to the Runoff Business, the results of which are included in discontinued operations and the balances as of
December 31, 2012 of which have been included in assets or liabilities held for sale on the consolidated balance sheet.
The collectibility of reinsurance recoverables is subject to the solvency and willingness to pay of the reinsurer. White Mountains is selective in choosing its reinsurers, placing reinsurance principally with those reinsurers with a strong financial condition, industry ratings and underwriting ability. Management monitors the financial condition and ratings of its reinsurers on an ongoing basis. See Note 4 —“Third-Party Reinsurance” in the accompanying Consolidated Financial Statements for additional information on White Mountains’ reinsurance programs.

5. White Mountains’ Investment in Symetra Common Shares

In September 2011, the U.S. Federal Reserve Bank (the “Fed”) began “Operation Twist”, which decreased long-term interest rates on fixed maturity investments. Under Operation Twist, the Fed sold shorter-term U.S. treasury securities, which have maturities of generally 3 years or less, to fund the purchase of longer-term U.S. securities, with maturities between
6 and 30 years. In December 2012, the Fed stated that it expects to continue to take actions to keep long-term interest rates low until unemployment reaches 6.5%. Lower long-term interest rates tend to reduce the return on equity that life insurers earn as they reinvest their cash flows from higher yielding long duration bonds into lower yielding long duration bonds. Quoted stock prices of life insurers tend to be highly correlated with their return on equity. Thus, as long-term interest rates decline, the quoted stock prices of life insurers tend to decline. At the same time, lower interest rates tend to increase the stated GAAP book values of life insurance companies, primarily from unrealized gains on fixed income investments, as the assets are marked-to-market, but the liabilities are not. Thus, the precipitous decline in long-term interest rates that occurred with Operation Twist caused a significant decline in the quoted stock prices of life insurance companies and an even more significant decline in those prices relative to stated GAAP book value. As a result, the quoted stock price of many life insurance companies at December 31, 2011, including Symetra, was well below their stated GAAP book value, a trend inconsistent with historical patterns.
White Mountains accounts for its investment in Symetra common shares using the equity method of accounting. Under the equity method, the GAAP carrying value of White Mountains’ investment in Symetra common shares is normally equal to the percentage of Symetra’s GAAP book value represented by White Mountains’ common share ownership, which was 15% at December 31, 2012 and 2011.  Under GAAP, a decline in the fair value of an investment is considered to be other-than-temporary when the fair value of the investment is not expected to recover to its GAAP carrying value in the near term.  Declines in the fair value of an investment that are considered to be other-than-temporary are recognized as a write-down to the GAAP carrying value of the investment. Having observed the divergence between the quoted market price for Symetra’s common shares and its GAAP carrying value, management evaluated White Mountains’ investment in Symetra common shares to determine whether an other-than-temporary impairment under GAAP existed at December 31, 2011.  As a result of this evaluation, management concluded that White Mountains’ investment in Symetra common shares was other-than-temporarily impaired and wrote down the GAAP book value of the investment to its estimated fair value of $261 million at December 31, 2011, or approximately $15 per Symetra common share.

100


The GAAP fair value of an investment is the price that would be paid by a market participant to acquire it in the investment’s principal or most advantageous market.  For investments that are publicly traded, quoted market prices generally provide the best measurement of GAAP fair value. However, a decline in the quoted market price of an investment below its GAAP carrying value is not necessarily indicative of a loss in value that is other-than-temporary, and in circumstances where the characteristics of the investment being measured are not the same as those for which quoted market prices are available, unadjusted quoted market prices do not represent GAAP fair value.  White Mountains’ investment in Symetra common shares is different than the shares that are traded on the public stock exchange, principally due to the size of its position and its representation on Symetra’s Board of Directors.  In circumstances like this, GAAP requires that fair value be determined giving consideration to multiple valuation techniques.  Management considered three different valuation techniques to determine the GAAP fair value of White Mountains’ investment in Symetra common shares at December 31, 2011. A description of each technique follows.

Valuation techniques based on actuarial appraisals
When determining the value of life insurance holding companies that are acquisition targets, market participants commonly utilize an approach that values the company as the sum of (A) adjusted statutory net worth of any regulated life insurance companies (i.e. statutory surplus plus asset valuation reserve) plus the GAAP net assets of any non-life businesses, less holding company debt and (B) the present value of future earnings related to business in force as of the valuation date plus the present value of future earnings related to business written after the valuation date.  White Mountains used this approach when it acquired its initial investment in Symetra in 2004.  Part A of the calculation can be performed using observable inputs from the statutory and GAAP financial statements.  Part B of the calculation requires a large number of actuarial calculations including assumptions such as discount rates, mortality, persistency and future investment results that, while based on historical data and are supportable, are nonetheless judgmental and largely unobservable.  For Symetra, part A is approximately $15 per share as of December 31, 2011.  Symetra management provided White Mountains with an actuarial appraisal that demonstrates that part B would be a meaningful positive value in most reasonable scenarios.  When determining the GAAP fair value of White Mountains’ investment in Symetra common shares at December 31, 2011, management ascribed the greatest weight to part A, as it is observable and less subjective.

Valuation techniques based on multiples from recent transactions
As described in “Non-GAAP Financial Measures”, White Mountains uses growth in adjusted book value to assess Symetra’s financial performance.  Adjusted book value excludes unrealized gains and losses from Symetra’s fixed maturity investment portfolio.  Life insurance industry analysts and market participants commonly use multiples of adjusted book value per share to determine relative values of companies in the life insurance industry.
In December 2011, Tokio Marine announced that it had agreed to acquire Delphi Financial Group (“Delphi”) for $2.7 billion. The acquisition price for that transaction represented a multiple of approximately 1.6 times Delphi’s September 30, 2011 adjusted book value of $1.6 billion. The acquisition price of $43.875 per share represented a premium of approximately 73% over Delphi’s last traded market price prior to the announcement of the acquisition.  If the same adjusted book value and market price multiples were applied to Symetra at December 31, 2011, the estimated fair value would range from $16 to $30 per share.
The Delphi acquisition highlights the wide disparity between values of life insurance companies based on quoted market prices and the value of those companies in a private market transaction.  However, the range of fair value estimates generated by applying the adjusted book value per share multiple and market premium observed in the Delphi acquisition is wide, and there have been no other significant acquisitions of life insurance companies in 2011.  Therefore, management did not ascribe significant weight to valuations determined using the adjusted book value per share multiple or market price premium observed in recent acquisition activity when determining the GAAP fair value of White Mountains’ investment in Symetra common shares at December 31, 2011.

Valuation techniques based on quoted market prices
White Mountains’ representation on Symetra’s Board of Directors gives it the ability to exercise significant influence over Symetra’s operations and policies.  Generally, market participants are willing to pay a premium to obtain the ability to exert influence over the operations and policies of an investee, which is not reflected in the quoted market price of Symetra’s common shares.  There is no reliable means to calculate the value of this premium for an investment in a life insurance company.  The actuarial appraisals used by market participants described above implicitly consider the ability to influence an investee’s operations and policies in the actuarial assumptions underlying projected future earnings, but the value associated with the ability to exert influence is not explicitly calculated separately from other components of value.  As a result, management did not ascribe significant weight to valuations based on quoted market prices when determining the GAAP fair value of White Mountains’ investment in Symetra common shares at December 31, 2011, as the premium associated with the ability to exert influence over the operations and policies of Symetra is unobservable and highly subjective.

101


After considering all of the above, management determined that the best estimate of the GAAP fair value of White Mountains’ investment in Symetra’s common shares at December 31, 2011 was $15 per share, which approximated Symetra’s adjusted statutory-basis net worth. The write down of $199 million to $261 million represented management’s best estimate of the amount by which the value of the investment had been other-than-temporarily impaired for GAAP at that date. After-tax, this represented a reduction of White Mountains adjusted book value per share of $6. Given the scarcity of relevant observable inputs and the wide range of estimates developed under the approaches used, the estimated GAAP fair value of White Mountains’ investment in Symetra’s common shares involved a significant degree of judgment, is very subjective in nature and, accordingly, is considered a Level 3 fair value measurement.
An other-than-temporary impairment for GAAP does not equate to a permanent impairment in value. The reasons why management concluded that an other-than-temporary impairment for GAAP existed at December 31, 2011 related to the environment in which life insurance companies operated and not from reasons specific to Symetra itself.  Symetra has recorded solid growth in adjusted book value per share since the financial crisis at the end of 2008, continues to pay quarterly dividends to its shareholders and has maintained strong financial strength and creditworthiness ratings and capital ratios.  Management does not believe that the write-down in 2011 is an indication of impairment in Symetra’s long-term intrinsic business value. At December 31, 2012 the GAAP carrying value of White Mountains’ investment in the Symetra common shares was $351 million, which reflects White Mountains’ equity in Symetra’s earnings and unrealized investment gains as well as the amortization of the basis difference that arose upon recognition of the impairment in 2011 (see Note 15). Management does not believe that the investment in Symetra’s common shares is other-than-temporarily impaired at December 31, 2012.

FORWARD-LOOKING STATEMENTS

The information contained in this report may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical facts, included or referenced in this report which address activities, events or developments which White Mountains expects or anticipates will or may occur in the future are forward-looking statements. The words “will”, “believe,” “intend,” “expect,” “anticipate,” “project,” “estimate,” “predict” and similar expressions are also intended to identify forward-looking statements. These forward-looking statements include, among others, statements with respect to White Mountains:

changes in adjusted book value per share or return on equity;
business strategy;
financial and operating targets or plans;
incurred losses and the adequacy of its loss and LAE reserves and related reinsurance;
projections of revenues, income (or loss), earnings (or loss) per share, dividends, market share or other financial forecasts;
expansion and growth of its business and operations; and
future capital expenditures.

These statements are based on certain assumptions and analyses made by White Mountains in light of its experience and perception of historical trends, current conditions and expected future developments, as well as other factors believed to be appropriate in the circumstances. However, whether actual results and developments will conform with its expectations and predictions is subject to a number of risks and uncertainties that could cause actual results to differ materially from expectations, including:

the risks associated with Item 1A of this Report on Form 10-K;
claims arising from catastrophic events, such as hurricanes, earthquakes, floods or terrorist attacks;
the continued availability of capital and financing;
general economic, market or business conditions;
business opportunities (or lack thereof) that may be presented to it and pursued;
competitive forces, including the conduct of other property and casualty insurers and reinsurers;
changes in domestic or foreign laws or regulations, or their interpretation, applicable to White Mountains, its competitors or its clients;
an economic downturn or other economic conditions adversely affecting its financial position;
recorded loss reserves subsequently proving to have been inadequate;
actions taken by ratings agencies from time to time, such as financial strength or credit ratings downgrades or placing ratings on negative watch; and
other factors, most of which are beyond White Mountains’ control.


102


Consequently, all of the forward-looking statements made in this report are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by White Mountains will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, White Mountains or its business or operations. White Mountains assumes no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events or otherwise.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

White Mountains’ consolidated balance sheet includes a substantial amount of assets and liabilities whose fair values are subject to market risk. The term market risk refers to the risk of loss arising from adverse changes in interest rates, credit spreads, equity markets prices and other relevant market rates and prices. Due to White Mountains’ sizable investment portfolio market risk can have a significant effect on White Mountains’ consolidated financial position.

Interest Rate and Credit Spread Risk
Fixed Maturity Portfolios.  In connection with the Company’s consolidated insurance and reinsurance subsidiaries, White Mountains invests in interest rate sensitive securities, primarily debt securities. White Mountains generally manages the interest rate risk associated with its portfolio of fixed maturity and convertible fixed maturity investments by monitoring the average duration of the portfolio. White Mountains’ fixed maturity and convertible fixed maturity portfolios are comprised primarily of investment grade corporate securities; U.S. government and agency securities; foreign government, agency and provincial obligations; preferred stocks; asset-backed and mortgage-backed securities; and municipal obligations.
Increases and decreases in prevailing interest rates generally translate into decreases and increases in fair values of fixed maturity and convertible fixed maturity investments, respectively. Additionally, fair values of interest rate sensitive instruments may be affected by the creditworthiness of the issuer, prepayment options, relative values of alternative investments, the liquidity of the instrument and other market factors.
The table below summarizes the estimated effects of hypothetical increases and decreases in market interest rates on White Mountains’ fixed maturity and convertible fixed maturity investments. Size of interest rate decreases may be limited in order to floor interest rates at a de minimis level.

The magnitude of the fair value decrease in rising rates scenarios may be more significant than the fair value increase in comparable falling rates scenarios. This can occur because (a) the analysis floors interest rates at a de minimis level in falling rate scenarios, muting price increases, (b) portions of the fixed income portfolio may be callable, muting price increases in falling interest rate scenarios and or (c) portions of the fixed income portfolio may experience cash flow extension in higher interest rate environments, which generally results in lower prices.

103


White Mountains’ overall fixed maturity investment strategy is to purchase securities that are attractively priced in relation to their investment risks. Widening and tightening of credit spreads generally translate into decreases and increases in fair values of fixed maturity investments, respectively. Size of credit spread tightening may be limited in order to floor yields of non-government bonds above short term government bond yields. The table below summarizes the estimated effects of hypothetical widening and tightening of pre-tax credit spreads on White Mountains’ fixed maturity and convertible fixed maturity portfolio.

(1) Fair value does not include $6.8 of defaulted bonds and $36.6 of convertibles whose market values are significantly influenced by the underlying stock.
Assumes no sensitivity to general credit spread movements for these securities.     

The magnitude of the fair value decrease in wider credit spread scenarios may be more significant than the fair value increase in comparable tighter credit spread scenarios. This can occur because the analysis limits the credit spread tightening in order to floor yields of non-government bonds above short government bond yields, muting price increases.

Equity Price Risk
The carrying values of White Mountains’ common equity securities and other long-term equity investments are based on quoted market prices or management’s estimates of fair value as of the balance sheet date. Market prices of common equity securities, in general, are subject to fluctuations.  These fluctuations could cause the amount realized upon sale or exercise of these instruments to differ significantly from the current reported value. The fluctuations may result from perceived changes in the underlying economic characteristics of the investment, the relative price of alternative investments, supply and demand imbalances for a particular security, or other market factors. Assuming a hypothetical 10% increase or decrease in the equity market at December 31, 2012, the carrying value of White Mountains’ equity securities would have increased or decreased by approximately $132 million pre-tax.


104


Long-term obligations
White Mountains carries its financial instruments on its balance sheet at fair value with the exception of its fixed-rate, long-term indebtedness and the SIG Preference Shares, which are recorded as non-controlling interest.

Variable Annuity Guarantee Risk
White Mountains entered into an agreement to reinsure death and living benefit guarantees associated with certain variable annuities issued in Japan. The reinsurance agreement assumes risk related to a shortfall between the account value and the guaranteed value that must be paid by the ceding company to an annuitant or to an annuitant’s beneficiary in accordance with the underlying annuity contracts. Generally, the liabilities associated with these guarantees increase with declines in the equity markets, interest rates and currencies against the Japanese yen, as well as with increases in market volatilities. The liability is also affected by annuitant-related actuarial assumptions, including surrender and mortality rates. At December 31, 2012, the total liability for the reinsured variable annuity guarantees was $442 million.
WM Life Re uses derivative instruments, including put options, interest rate swaps, total return swaps on bond indices and forward and futures contracts on currency pairs and government bonds to mitigate the risks associated with changes in the fair value of the reinsured variable annuity guarantees. At December 31, 2012, the fair value of these derivative instruments was $98 million. In addition, WM Life Re held approximately $394 million of cash and fixed maturity investments at December 31, 2012.
WM Life Re measures its net exposure to changes in relevant interest rates, foreign exchange rates and equity markets on a daily basis and adjusts its economic hedge positions within risk guidelines established by senior management. WM Life Re also monitors the effects of annuitant-related experience against actuarial assumptions (including surrender and mortality rates) on a weekly basis and adjusts relevant assumptions and economic hedge positions if required. While WM Life Re actively manages its economic hedge positions, several factors, including policyholder behavior and mismatches between underlying variable annuity funds and the hedge indices, may result in the failure of economic hedges to perform as intended. See discussion of fair value measurement of reinsured variable annuity liabilities and derivative instruments and sensitivity analyses of significant inputs in “CRITICAL ACCOUNTING ESTIMATES — Fair Value Measurements” on page 90.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. Summary of Significant Accounting Policies

Basis of Presentation
The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and include the accounts of White Mountains Insurance Group, Ltd. (the “Company” or the “Registrant”), its subsidiaries (collectively with the Company, “White Mountains”) and other entities required to be consolidated under GAAP. The Company is an exempted Bermuda limited liability company whose principal businesses are conducted through its property and casualty insurance and reinsurance subsidiaries and affiliates. The Company’s headquarters is located at 14 Wesley Street, Hamilton, Bermuda HM 11, its principal executive office is located at 80 South Main Street, Hanover, New Hampshire 03755-2053 and its registered office is located at Clarendon House, 2 Church Street, Hamilton, Bermuda HM 11. White Mountains’ reportable segments are OneBeacon, Sirius Group, HG Global/BAM and Other Operations. 
The OneBeacon segment consists of OneBeacon Insurance Group, Ltd. (“OneBeacon Ltd.”), an exempted Bermuda limited liability company that owns a family of U.S. based property and casualty insurance companies (collectively “OneBeacon”). OneBeacon is a specialty property and casualty insurance writer that offers a wide range of insurance products through independent agencies, regional and national brokers, wholesalers and managing general agencies. As of December 31, 2012 and 2011, White Mountains owned 75.2% and 75.5% of OneBeacon Ltd.’s outstanding common shares.
As discussed further in Note 2, OneBeacon entered into a definitive agreement to sell its runoff business in October 2012 (the “Runoff Transaction”) and sold its AutoOne Insurance business (“AutoOne”) in February 2012.  Accordingly, the runoff business and AutoOne are presented as discontinued operations. Assets and liabilities associated with the runoff business as of December 31, 2012 and AutoOne as of December 31, 2011 have been presented as held for sale in the financial statements. Prior year income statement and cash flow amounts have been reclassified to conform to the current year’s presentation. (See Note 20 for discontinued operations).
The Sirius Group segment consists of Sirius International Insurance Group, Ltd., an exempted Bermuda limited liability company, and its subsidiaries (collectively, “Sirius Group”). Sirius Group provides insurance and reinsurance products for property, accident and health, aviation and space, trade credit, marine, agriculture and certain other exposures on a worldwide basis through its subsidiaries, Sirius International Insurance Corporation (“Sirius International”), Sirius America Insurance Company (“Sirius America”) and Lloyds Syndicate 1945 (“Syndicate 1945”). Sirius Group also specializes in the acquisition and management of runoff insurance and reinsurance companies both in the United States and internationally through its White Mountains Solutions division (“WM Solutions”).
The HG Global/BAM segment consists of White Mountains’ investment in HG Global Ltd. (“HG Global”) and the consolidated results of Build America Mutual Assurance Company (“BAM”). During the third quarter of 2012, White Mountains capitalized HG Global with approximately $600 million to fund the start-up of BAM. BAM is a municipal bond insurer domiciled in New York that was established to provide insurance on bonds issued to support essential U.S. public purposes such as schools, utilities, core governmental functions and existing transportation facilities. HG Global, together with its subsidiaries, provided the initial capitalization of BAM through the purchase of $503 million of surplus notes issued by BAM (the “BAM Surplus Notes”). HG Global, through its wholly-owned subsidiary, HG Re Ltd. (“HG Re”), also provides 15%-of-par, first loss reinsurance protection for policies underwritten by BAM. As of December 31, 2012, White Mountains owned 97.3% of HG Global's preferred equity and 88.7% of its common equity. White Mountains does not have an ownership interest in BAM, which is a mutual insurance company owned by its members. However, GAAP requires White Mountains to consolidate BAM's results in its financial statements. BAM's results are attributed to non-controlling interests.
White Mountains’ Other Operations segment consists of the Company and its intermediate holding companies, its wholly-owned investment management subsidiary, White Mountains Advisors LLC (“WM Advisors”), White Mountains’ variable annuity reinsurance business, White Mountains Life Reinsurance (Bermuda) Ltd. (“WM Life Re”), which is in runoff, as well as various other entities not included in other segments. For 2011, the Other Operations segment also included the consolidated results of the Tuckerman Capital, LP fund (“Tuckerman Fund I”). On December 31, 2011, Tuckerman Fund I was dissolved and all of the net assets of the fund were distributed to the owners of the fund, of which White Mountains owned approximately 94%. In conjunction with the dissolution, White Mountains received a portion of the shares of Hamer, LLC (“Hamer”) and Bri-Mar Manufacturing, LLC (“Bri-Mar”), two small manufacturing companies.  Prior to the dissolution, Tuckerman Fund I was consolidated within White Mountains' financial statements.  The consolidated results of Hamer and Bri-Mar are included in the Other Operations segment from January 1, 2012 through September 30, 2012, from which point these companies are no longer consolidated by White Mountains.

F-5


White Mountains’ discontinued operations consist of Esurance Holdings, Inc. and its subsidiaries (“Esurance Insurance”), Answer Financial Inc. and its subsidiaries (“AFI”), the Runoff Transaction and AutoOne.  Esurance Insurance wrote personal auto insurance directly to customers in 30 states through its website and over the phone and also sold other lines of personal insurance for unaffiliated insurance companies.  Esurance Insurance also wrote personal auto policies through select online agents and provided other insurance products through partnerships with industry leading online providers.  Esurance Insurance earned commissions and fees by referring to unaffiliated insurance companies those shoppers that it could not underwrite because of pricing or underwriting eligibility.  AFI sold insurance online and through call centers for both Esurance Insurance and unaffiliated companies utilizing a comparison quoting platform.  The OneBeacon runoff business included assets, liabilities and capital that was principally related to non-specialty commercial lines and certain other runoff business that it no longer writes, including nearly all of of its asbestos and environmental reserves. AutoOne was formed by OneBeacon in 2001 to provide products and services to automobile assigned risk markets primarily in New York and New Jersey.
All significant intercompany transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain amounts in the prior period financial statements have been reclassified to conform to the current presentation.

Significant Accounting Policies

Investment Securities
At December 31, 2012, White Mountains’ invested assets consisted of securities and other investments held for general investment purposes.  White Mountains’ portfolio of fixed maturity investments and common equity securities held for general investment purposes are classified as trading and are reported at fair value as of the balance sheet date.  Changes in unrealized gains and losses are reported pre-tax in revenues. Realized investment gains and losses are accounted for using the specific identification method and are reported pre-tax in revenues. Premiums and discounts on all fixed maturity investments are accreted to income over the anticipated life of the investment.
White Mountains’ invested assets that are measured at fair value include fixed maturity securities, common and preferred equity securities, convertible fixed maturity securities and other long-term investments, such as interests in hedge funds and private equities. In determining its estimates of fair value, White Mountains uses a variety of valuation approaches and inputs. Whenever possible, White Mountains estimates fair value using valuation methods that maximize the use of quoted prices and other observable inputs.
As of both December 31, 2012 and 2011, approximately 95% of the investment portfolio recorded at fair value was priced based upon quoted market prices or other observable inputs. Investments valued using Level 1 inputs include fixed maturities, primarily investments in U.S. Treasuries, common equities and short-term investments, which include U.S. Treasury Bills. Investments valued using Level 2 inputs comprise fixed maturities including corporate debt, state and other governmental debt, convertible fixed maturity securities and mortgage and asset-backed securities. Fair value estimates for investments that trade infrequently and have few or no observable market prices are classified as Level 3 measurements. Level 3 fair value estimates based upon unobservable inputs include White Mountains’ investments in hedge funds and private equity funds, as well as investments in certain debt securities, including asset-backed securities, where quoted market prices are unavailable. White Mountains uses brokers and outside pricing services to assist in determining fair values. For investments in active markets, White Mountains uses the quoted market prices provided by outside pricing services to determine fair value. The outside pricing services used by White Mountains have indicated that if no observable inputs are available for a security, they will not provide a price. In those circumstances, White Mountains estimates the fair value using industry standard pricing models and observable inputs such as benchmark interest rates, matrix pricing, market comparables, broker quotes, issuer spreads, bids, offers, credit rating prepayment speeds and other relevant inputs. White Mountains performs procedures to validate the market prices obtained from the outside pricing sources. Such procedures, which cover substantially all of its fixed maturity investments include, but are not limited to, evaluation of model pricing methodologies and review of the pricing services’ quality control processes and procedures on at least an annual basis, comparison of market prices to prices obtained from a different independent pricing vendors on at least a semi-annual basis, monthly analytical reviews of certain prices, and review of assumptions utilized by the pricing service for selected measurements on an ad hoc basis throughout the year. White Mountains also performs back-testing of selected sales activity to determine whether there are any significant differences between the market price used to value the security prior to sale and the actual sale price on an ad-hoc basis throughout the year. Prices provided by the pricing services that vary by more than 5% and $1 million from the expected price based on these procedures are considered outliers. In circumstances where the results of White Mountains’ review process do not appear to support the market price provided by the pricing services, White Mountains challenges the price.  During the past year, approximately fifteen securities fell outside White Mountains’ expected results, thereby triggering the challenge with the pricing service. If White Mountains cannot gain satisfactory evidence to support the challenged price, it relies upon its own pricing methodologies to estimate the fair value of the security in question. The fair values of such securities are considered to be Level 3 measurements.

F-6


White Mountains’ investments in debt securities, including asset-backed securities, are generally valued using matrix and other pricing models. Key inputs include benchmark yields, benchmark securities, reported trades, issuer spreads, bids, offers, credit ratings and prepayment speeds.  Income on mortgage-backed and asset-backed securities is recognized using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When actual prepayments differ significantly from anticipated prepayments, the estimated economic life is recalculated and the remaining unamortized premium or discount is amortized prospectively over the remaining economic life.
Short-term investments consist of money market funds, certificates of deposit and other securities which, at the time of purchase, mature or become available for use within one year.  Short-term investments are carried at amortized cost, which approximated fair value as of December 31, 2012 and 2011.

Other Long-term Investments
White Mountains’ other long-term investments comprise primarily of hedge funds and private equity funds. White Mountains made the fair value election for most of its investments in hedge funds and private equity interests. For the hedge fund and private equity investments for which White Mountains has made the fair value election, changes in fair value are reported in revenues on a pre-tax basis. For those hedge fund and private equity investments for which White Mountains has not made the fair value election, White Mountains accounts for its interests under the equity method.

Derivative Financial Instruments
White Mountains holds a variety of derivative financial instruments for both risk management and investment purposes. White Mountains recognizes all derivatives as either assets or liabilities, measured at fair value, in the consolidated balance sheets.

Warrants
White Mountains holds warrants to acquire common shares of Symetra which are included as investments in unconsolidated affiliates. White Mountains also holds warrants that it has received in the restructuring (e.g., securities received from bankruptcy proceedings) of certain of its common equity and/or fixed maturity investments. The Symetra warrants held by White Mountains are entitled to dividends declared to common shareholders. White Mountains accounts for its investments in warrants as derivatives.

Derivatives—Variable Annuity Reinsurance
White Mountains has entered into agreements to reinsure death and living benefit guarantees associated with certain variable annuities in Japan through its wholly owned subsidiary, WM Life Re. The accounting for benefit guarantees differs depending on whether or not the guarantee is classified as a derivative or an insurance liability.
Guaranteed minimum accumulation benefits (“GMABs”) are paid to an annuitant for any shortfall between accumulated account value at the end of the accumulation period and the annuitant’s total deposit, less any withdrawal payments made to the annuitant during the accumulation period. GMABs meet the definition of a derivative for accounting purposes. Therefore, GMABs are carried at fair value, with changes thereon recognized in income in the period of the change. The liability for the reinsured GMAB contracts has been determined using internal valuation models that use assumptions for interest rates, equity markets, foreign exchange rates and market volatilities at the valuation date, as well as annuitant-related actuarial assumptions, including surrender and mortality rates.
If an annuitant dies during the accumulation period of an annuity contract, guaranteed minimum death benefits (“GMDBs”) are paid to the annuitant’s beneficiary for shortfalls between accumulated account value at the time of an annuitant’s death and the annuitant’s total deposit, less any living benefit payments or withdrawal payments previously made to the annuitant. White Mountains has elected to measure its GMDB liabilities at fair value.
The valuation of these liabilities involves significant judgment and is subject to change based upon changes in capital market assumptions and emerging surrender and mortality experience of the underlying contracts in force.
WM Life Re has entered into derivative contracts that are designed to economically hedge against changes in the fair value of living and death benefit liabilities associated with its variable annuity reinsurance arrangements. The derivatives include futures and over-the-counter option contracts on interest rates, major bond and equity indices, and foreign currencies. All WM Life Re’s derivative instruments are recorded as assets or liabilities at fair value on the balance sheet within other assets. These derivative financial instruments do not meet the criteria for hedge accounting treatment, and accordingly, changes in fair value are recognized in the current period as gains or losses in the income statement within other revenues.
 WM Life Re includes the effect of counterparty credit risk when determining the fair value of its derivative contracts and its GMAB and GMDB liabilities.

Cash
Cash includes amounts on hand and demand deposits with banks and other financial institutions. Amounts presented in the statement of cash flows are shown net of balances acquired and sold in the purchase or sale of the Company’s consolidated subsidiaries and exclude changes in amounts of restricted cash (See Note 8).

Insurance and Reinsurance Operations
White Mountains accounts for insurance and reinsurance policies that it writes in accordance with ASC 944. Premiums written are recognized as revenues and are earned ratably over the term of the related policy or reinsurance treaty. Unearned premiums represent the portion of premiums written that are applicable to future insurance or reinsurance coverage provided by policies or treaties in force.  White Mountains charges fees on certain of its insurance policies. Refundable fees are classified with premiums and recognized in earnings over the policy term. Fees that represent a reimbursement of expenses, such as installment fees, are recorded as a reduction of underwriting expenses.
Deferred acquisition costs represent commissions, premium taxes, brokerage expenses and other costs which are directly attributable to and vary with the production of business. These costs are deferred and amortized to the extent they relate to successful contract acquisitions over the applicable premium recognition period as insurance and reinsurance acquisition expenses. Deferred acquisition costs are limited to the amount expected to be recovered from future earned premiums and anticipated investment income. This limitation is referred to as a premium deficiency. A premium deficiency is recognized if the sum of expected loss and loss adjustment expenses (“LAE”), expected dividends to policyholders, unamortized acquisition costs, and maintenance costs exceeds related unearned premiums and anticipated investment income. A premium deficiency is recognized by charging any unamortized acquisition costs to expense to the extent required in order to eliminate the deficiency. If the premium deficiency exceeds unamortized acquisition costs then a liability is accrued for the excess deficiency.
Losses and LAE are charged against income as incurred. Unpaid insurance losses and LAE are based on estimates (generally determined by claims adjusters, legal counsel and actuarial staff) of the ultimate costs of settling claims, including the effects of inflation and other societal and economic factors. Unpaid reinsurance losses and LAE are based primarily on reports received from ceding companies and actuarial projections. Unpaid loss and LAE reserves represent management’s best estimate of ultimate losses and LAE, net of estimated salvage and subrogation recoveries, if applicable. Such estimates are regularly reviewed and updated and any adjustments resulting there from are reflected in current operations. The process of estimating loss and LAE involves a considerable degree of judgment by management and the ultimate amount of expense to be incurred could be considerably greater than or less than the amounts currently reflected in the financial statements.
OneBeacon discounts certain of its long-term workers compensation loss and LAE reserves when such liabilities constitute unpaid but settled claims under which the payment pattern and ultimate costs are fixed and determinable on an individual claim basis. OneBeacon discounts these reserves using an average discount rate which is determined based on the various assumptions including consideration of when the claims will be settled (3.5% and 4.5% at December 31, 2012 and 2011). As of December 31, 2012, the discount on OneBeacon’s workers compensation loss and LAE reserves amounted to $4.6 million (excluding $77.9 million on reserves classified as discontinued operations). As of December 31, 2011, the discount on OneBeacon’s workers compensation loss and LAE reserves amounted to $108.3 million.
White Mountains’ insurance and reinsurance subsidiaries enter into ceded reinsurance contracts from time to time to protect their businesses from losses due to concentration of risk, to manage their operating leverage ratios and to limit losses arising from catastrophic events. Such reinsurance contracts are executed through excess of loss treaties and catastrophe contracts under which the reinsurer indemnifies White Mountains for a specified part or all of certain types of losses over stipulated amounts arising from any one occurrence or event. White Mountains has also entered into quota share treaties with reinsurers under which all risks meeting prescribed criteria are covered on a pro-rata basis. The amount of each risk ceded by White Mountains is subject to maximum limits which vary by line of business and type of coverage.
Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured policies. The collectability of reinsurance recoverables is subject to the solvency of the reinsurers. White Mountains is selective in regard to its reinsurers, principally placing reinsurance with those reinsurers with a strong financial condition, industry ratings and underwriting ability. Management monitors the financial condition and ratings of its reinsurers on an ongoing basis.
Reinsurance premiums, commissions, expense reimbursements and reserves related to reinsured business are accounted for on a basis consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums ceded to other companies are reported as a reduction of premiums written. Expense allowances received in connection with reinsurance ceded have been accounted for as a reduction of the related policy acquisition costs and are deferred and amortized accordingly. Funds held by ceding companies represent amounts due to White Mountains in connection with certain assumed reinsurance agreements in which the ceding company retains a portion of the premium to provide security against future loss payments. The funds held by ceding companies are generally invested by the ceding company and a contractually agreed interest amount is credited to the Company and recognized as investment income. Funds held under reinsurance treaties represent contractual payments due to the reinsurer that White Mountains has retained to secure obligations of the reinsurer. Such amounts are recorded as liabilities in the consolidated financial statements.
Accruals for contingent commission liabilities are established for reinsurance contracts that provide for the stated commission percentage to increase or decrease based on the loss experience of the contract. Changes in the estimated liability for such arrangements are recorded as contingent commissions. Accruals for contingent commission liabilities are determined through the review of the contracts that have these adjustable features and are estimated based on expected loss and LAE.

F-8


Municipal Bond Insurance
All of the contracts issued by BAM are accounted for as insurance contracts under ASC 944-605, Financial Guarantee Insurance Contracts. Premiums are received upfront and an unearned premium revenue liability, equal to the amount of the cash received, is established at contract inception. Premium revenues are recognized in revenue over the period of the contracts in proportion to the amount of insurance protection provided using a constant rate. The constant rate is calculated based on the relationship between the par outstanding in a given reporting period compared with the sum of each of the par amounts outstanding for all periods.
Deferred acquisition costs represent commissions, premium taxes, excise taxes and other costs which are directly attributable to and vary with the production of business. These costs are deferred and amortized to the extent they relate to successful contract acquisitions over the applicable premium recognition period as acquisition expenses. Deferred acquisition costs are limited to the amount expected to be recovered from future earned premiums and anticipated investment income.

Mandatory Shared Market Mechanisms
As a condition to its licenses to do business in certain states, White Mountains’ insurance operations must participate in various mandatory shared market mechanisms commonly referred to as “residual” or “involuntary” markets. These markets generally consist of risks considered to be undesirable from a standard or routine underwriting perspective. Each state dictates the levels of insurance coverage that are mandatorily assigned to participating insurers within these markets. The total amount of such business an insurer must accept in a particular state is generally based on that insurer’s market share of voluntary business written within that state. In certain cases, White Mountains is obligated to write business from shared market mechanisms at a future date based on its historical market share of all voluntary policies written within that state. Involuntary business generated from mandatory shared market mechanisms is accounted for as direct insurance business or as assumed reinsurance depending upon the structure of the mechanism.
OneBeacon’s market assignments are typically required to be written in the current period, however, in certain cases OneBeacon is required to accept policy assignments at a future date. Anticipated losses associated with future market assignments are recognized when the amount of such anticipated losses is determined to be probable and can be reasonably estimated.

Insurance-related Assessments
Under existing guaranty fund laws in all states, insurers licensed to do business in those states can be assessed for certain obligations of insolvent insurance companies to policyholders and claimants. White Mountains records guaranty fund assessments when it is probable that an assessment will be made and the amount can be reasonably estimated.

Deferred Software Costs
White Mountains capitalizes costs related to computer software developed for internal use during the application development stage of software development projects. These costs generally consist of certain external, payroll and payroll-related costs. White Mountains begins amortization of these costs once the project is completed and ready for its intended use. Amortization is on a straight-line basis and over a useful life of three to five years. At December 31, 2012 and 2011, White Mountains had unamortized deferred software costs of $17.1 million and $22.8 million.

Federal and Foreign Income Taxes
A significant portion of White Mountains’ subsidiaries file consolidated tax returns in the United States. Income earned or losses generated by companies outside the United States are generally subject to an overall effective tax rate lower than that imposed by the United States.
Deferred tax assets and liabilities are recorded when a difference between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts for tax purposes exists, and for other temporary differences. The deferred tax asset or liability is recorded based on tax rates expected to be in effect when the difference reverses. The deferred tax asset is recognized when it is more likely than not that it will be realized.

Foreign Currency Exchange
The U.S. dollar is the functional currency for all of White Mountains’ businesses except for Sirius International, the Canadian reinsurance operations of Sirius America and certain other smaller international activities.  White Mountains also invests in securities denominated in foreign currencies. Assets and liabilities recorded in these foreign currencies are translated into U.S. dollars at exchange rates in effect at the balance sheet date, and revenues and expenses are converted using the average exchange rates for the period. Net foreign exchange gains and losses arising from the translation are generally reported in shareholders’ equity, in accumulated other comprehensive income or loss.

F-9


Assets and liabilities relating to foreign operations are translated into the functional currency using current exchange rates; revenues and expenses are translated into the functional currency using the weighted average exchange rate for the period.  The resulting exchange gains and losses are reported as a component of net income in the period in which they arise. As of December 31, 2012 and 2011, White Mountains had unrealized foreign currency translation gains of $85.7 million and $46.1 million recorded in accumulated other comprehensive income on its consolidated balance sheet.

Non-controlling Interest
Non-controlling interests consist of the ownership interests of non-controlling shareholders in consolidated subsidiaries, and are presented separately on the balance sheet. The portion of comprehensive income attributable to non-controlling interests is presented net of related income taxes in the statement of operations and comprehensive income. The percentage of the non-controlling shareholders’ ownership interest in OneBeacon Ltd. at December 31, 2012 and 2011 was 24.8% and 24.5%.
In 2012, HG Global was capitalized with $594.5 million from White Mountains and $14.5 million from certain management members of BAM, the latter of which is included in non-controlling interest. Upon closing, certain BAM management members also received additional common and preferred shares of HG Global that resulted in a $2.2 million allocation of the carrying value of White Mountains' investment in HG Global to the non-controlling interest, which was recorded as an adjustment to paid-in surplus in White Mountains' consolidated statement of changes in equity.
White Mountains is required to consolidate BAM in its GAAP financial statements. However, since BAM is a mutual insurance company that is owned by its members, BAM's results do not affect White Mountains' common shareholders' equity as they are attributable to non-controlling interests. For the year ended December 31, 2012, BAM reported $36.3 million in pre-tax losses that have been allocated to non-controlling interest.
On May 24, 2007, Sirius International Group, Ltd. (“SIG”), an intermediate holding company of Sirius Group, issued $250.0 million non-cumulative perpetual preference shares, with a $1,000 per share liquidation preference (the “SIG Preference Shares”), and received $245.7 million of proceeds, net of $4.3 million of issuance costs and commissions. These shares were issued in an offering that was exempt from the registration requirements of the Securities Act of 1933. Holders of the SIG Preference Shares receive dividends on a non-cumulative basis when and if declared by SIG. The holders of the SIG Preference Shares have the right to elect two directors to SIG’s board in the event of non-payment of dividends for six quarterly dividend periods. The right ceases upon the payment of dividends for four quarterly periods or the redemption of the SIG Preference Shares. In addition, SIG may not declare or pay dividends on its common shares (other than stock dividends and dividends paid for purposes of any employee benefit plans of SIG and its subsidiaries) unless it is current on its most recent dividend period. The dividend rate is fixed at an annual rate of 7.506% until June 30, 2017 and dividends are paid on a semi-annual basis. After June 30, 2017, the dividend rate will be paid at a floating annual rate, equal to the greater of (1) the 3 month LIBOR plus 3.20% or (2) 7.506% and dividends will be paid on a quarterly basis. The SIG Preference Shares are redeemable solely at the discretion of SIG on or after June 30, 2017 at their liquidation preference of $1,000 per share, plus any declared but unpaid dividends. Prior to June 30, 2017, SIG may elect to redeem the SIG Preference Shares at an amount equal to the greater of (1) the aggregate liquidation preference of the shares to be redeemed and (2) the sum of the present values of the aggregate liquidation preference of the shares to be redeemed and the remaining scheduled dividend payments on the shares to be redeemed (excluding June 30, 2017), discounted to the redemption date on a semi-annual basis at a rate equal to the rate on a comparable treasury issue plus 45 basis points. In the event of liquidation of SIG, the holders of the SIG Preference Shares would have preference over the common shareholders and would receive a distribution equal to the liquidation preference per share, subject to availability of funds. SIG Preference Shares and dividends thereon are included in non-controlling interest on the balance sheet and as non-controlling interest expense on the statement of income and comprehensive income.
At December 31, 2012 and 2011, the non-controlling equity interest in White Mountains, consolidated limited partnerships was $41.5 million and $54.2 million.  At December 31, 2012 and 2011, the non-controlling equity interest in A.W.G. Dewar Inc, a subsidiary of OneBeacon, was $2.8 million and $2.3 million. At December 31, 2012 and December 31, 2011, the non-controlling equity interest in Passage2Health Limited, a subsidiary of Sirius Group, was $0.2 million and $0.6 million.

Recently Adopted Changes in Accounting Principles

Transfers of Financial Assets and Amendments to FIN 46R
On June 12, 2009, the Financial Accounting Standards Board (“FASB”)  issued Accounting Standards Update (“ASU”)  2009-16, Accounting for Transfers of Financial Assets, an amendment of FASB Statement No. 140 (included in ASC 860) and ASU 2009-17, Amendments to FIN46(R) (included in ASC 810).  Both ASU 2009-16 and ASU 2009-17 became effective as of the beginning of the first annual reporting period that began after November 15, 2009. White Mountains adopted the new guidance on January 1, 2010.
Upon adoption, White Mountains determined that its ownership interest in Tuckerman Fund II did not meet the criteria for consolidation under the revised guidance for variable interest entities and, accordingly, effective January 1, 2010, White Mountains deconsolidated its investment in Tuckerman Fund II. Upon deconsolidation, White Mountains made the fair value election for its investment in Tuckerman Fund II and recognized an adjustment to decrease opening retained earnings by $0.4 million.

Policy Acquisition Costs
On January 1, 2012, White Mountains adopted ASU 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts (ASC 944). The new standard changes the types of policy acquisition costs that are eligible for deferral. Specifically, the new guidance limits deferrable costs to those that are incremental direct costs of contract acquisition and certain costs related to acquisition activities performed by the insurer, such as underwriting, policy issuance and processing, medical and inspection costs and sales force contract selling. The ASU defines incremental direct costs as those costs that result directly from and were essential to the contract acquisition and would not have been incurred absent the acquisition. Accordingly, under the new guidance, deferrable acquisition costs are limited to costs related to successful contract acquisitions. Acquisition costs that are not eligible for deferral are to be charged to expense in the period incurred.
 White Mountains adopted ASU 2010-26 prospectively. Upon adoption, certain acquisition costs, primarily a portion of the profit sharing commissions associated with OneBeacon’s collector car and boats business, no longer met the criteria for deferral.  During the year ended December 31, 2012, White Mountains recognized $5.6 million of expense related to such previously deferrable acquisition costs that, if White Mountains had adopted ASU 2010-26 retrospectively, would have been recognized during 2011.

Fair Value Measurements
On January 1, 2012, White Mountains adopted ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. The ASU clarifies existing guidance with respect to the concepts of highest and best use and valuation premise and measuring instruments classified within a reporting entity’s shareholders’ equity.  The ASU also clarifies disclosure requirements, requiring disclosure of quantitative information about unobservable inputs used in Level 3 fair value measurements. The ASU also amends existing guidance. In circumstances where a reporting entity manages a portfolio of financial assets and liabilities based on the net market and counterparty credit risk exposures, the ASU permits determination of the fair value of those instruments to be based on the net risk exposure. In addition, the ASU permits the application of premiums or discounts to be applied in a fair value measurement to the extent that market participants would consider them in valuing the financial instruments. The ASU also expands the required disclosures for Level 3 measurements, requiring that reporting entities provide a narrative description of the sensitivity of Level 3 fair value measurements to changes in unobservable inputs and the interrelationships between those inputs, if any.  (See Note 5).

Comprehensive Income
For fiscal periods beginning after December 15, 2011, ASU 2011-05, Comprehensive Income (ASC 220) became effective, which requires all components of comprehensive income to be reported in a continuous financial statement or in consecutive statements displaying the components of net income and the components of other comprehensive income. Since White Mountains presents comprehensive income in a continuous financial statement, adoption of ASU 2011-05 had no effect on White Mountains’ financial statement presentation.


F-11


Recent Accounting Pronouncements

Offsetting Assets and Liabilities
On December 16, 2011, the FASB issued ASU 2011-11, Disclosures about Offsetting Assets and Liabilities (ASC 210). The new standard expands the required disclosures in circumstance where either balances have been offset or the right of offset exists. The required disclosures are intended to provide information to enable financial statement users to evaluate the effect or potential effect of netting arrangements on a reporting entity’s financial position. Disclosures required under the new standard include the gross amount of assets and liabilities recognized; the amounts that have been offset to arrive at the amounts presented in the statement of financial position; and any amounts subject to an enforceable master netting arrangement, whether or not such amounts have been offset. In addition, a description of the rights of set off should be disclosed. ASU 2011-11 is effective for periods beginning on or after January 1, 2013. White Mountains is party to master netting arrangements in connection with the derivative instruments held by WM Life Re and discloses information regarding the amounts covered under such agreements as well as the amounts of collateral held and provided. Accordingly, White Mountains does not expect any significant changes to its disclosures upon adoption.

NOTE 2. Significant Transactions

Formation of HG Global and BAM
In 2012, White Mountains capitalized HG Global with $594.5 million to fund BAM, a newly formed mutual municipal bond insurer. As of December 31, 2012, White Mountains owned 97.3% of HG Global’s preferred equity and 88.7% of its common equity. HG Global, together with its subsidiaries, provided the initial capitalization of BAM through the purchase of $503.0 million of BAM Surplus Notes. Through HG Re, which had statutory capital of $412.0 million at December 31, 2012, HG Global provides first loss reinsurance protection for policies underwritten by BAM of up to 15% of par outstanding, on a per policy basis. HG Re’s obligations to BAM are collateralized in trusts, and there is an aggregate loss limit that is equal to the total assets in the collateral trusts at any point in time. For the year ended December 31, 2012, HG Global had pre-tax income of $14.2 million, which included $18.4 million of interest income on the BAM Surplus Notes. For the year ended December 31, 2012, BAM had a pre-tax loss of $36.3 million that was recorded in net loss attributable to non-controlling interests, which included $18.4 million of interest expense on the BAM Surplus Notes.

Sale of OneBeacon Runoff Business
On October 17, 2012, one of OneBeacon’s indirect wholly-owned subsidiaries, OneBeacon Insurance Group LLC, entered into a definitive agreement with Trebuchet US Holdings, Inc. (“Trebuchet”), a wholly-owned subsidiary of Armour Group Holdings Limited (together with Trebuchet, “Armour”), to sell its runoff business (the “Runoff Transaction”). Pursuant to the terms of the agreement, at closing OneBeacon will transfer to Trebuchet all of the issued and outstanding shares of common stock of certain legal entities that will contain the assets, liabilities (including gross and ceded loss reserves) and capital supporting the runoff business as well as certain elements of the runoff business infrastructure, including staff and office space. The transaction is subject to regulatory approvals.
For the year ended December 31, 2012, White Mountains recorded $91.5 million after-tax loss on sale and a $24.0 million in loss from operations, which included a $9.0 million after-tax loss related to an reduction in the workers compensation loss reserve discount rate on reserves being transferred as part of the sale (see Note 20).

WM Solutions
On December 3, 2012, WM Solutions acquired four runoff entities including Physicians Insurance Company of Ohio (“PICO”) and Citation Insurance Company (“Citation”) from PICO Holdings and two AIG runoff subsidiaries, American General Indemnity Company (“American General”) and American General Property Insurance Company (“American General Property”). The transactions resulted in a gain of $14.5 million recorded in other revenues.
On December 30, 2011, WM Solutions acquired the runoff loss reserve portfolio of Old Lyme, a Bermuda-based reinsurer in runoff, for $6.0 million in cash and a purchase note for $2.1 million (see Note 6).  The transaction resulted in a gain of $7.2 million recorded in other revenues.
On February 26, 2010, WM Solutions acquired Central National for $5 million in cash. Central National ceased writing business in 1989 and has operated under the control of the Nebraska Department of Insurance since 1990. The transaction resulted in a gain of $12.8 million recorded in other revenues.


F-12


Sale of AutoOne
On August 30, 2011, OneBeacon entered into a definitive agreement (the “Purchase Agreement”) to sell the AutoOne business to Interboro Holdings, Inc. (“Interboro”). On February 22, 2012, OneBeacon completed the sale of AutoOne to Interboro Holdings, Inc. (“Interboro”). OneBeacon formed AutoOne in 2001 to provide products and services to automobile assigned risk markets primarily in New York and New Jersey. OneBeacon transferred to the buyer AutoOne Insurance Company (“AOIC”) and AutoOne Select Insurance Company (“AOSIC”), which contained the assets, liabilities (including loss reserves and unearned premiums), and the capital of the AutoOne business, and transferred substantially all of the AutoOne infrastructure including systems and office space as well as certain staff.  As a result of the sale, AutoOne is reported as discontinued operations (see Note 20).

Sale of Esurance
On October 7, 2011, White Mountains completed the sale of Esurance Insurance and AFI to The Allstate Corporation (“Allstate”) for $700.0 million in excess of tangible book value.  White Mountains recorded a gain on the sale of $677.5 million in discontinued operations.  The transaction is subject to a true-up of the estimated tangible book value of the entities sold through the date of closing and certain other contingencies (see Note 19).

OneBeacon Personal Lines and Commercial Lines Sales
In July 2010, OneBeacon completed the sale of its traditional personal lines business (the “Personal Lines Transaction”) to Tower Group, Inc. (“Tower”). The Personal Lines Transaction included two insurance companies, York Insurance Company of Maine (“York”) and Massachusetts Homeland Insurance Company (“MHIC”), through which the majority of the traditional personal lines business was written on a direct basis.  Subsequent to the transaction, OneBeacon cedes to Tower, on a 100% quota share basis, traditional personal lines business not directly written by York and MHIC; and OneBeacon assumes, on a 100% quota share basis, certain specialty lines business written directly by York.  The Personal Lines Transaction also included two attorneys-in-fact managing the reciprocal insurance exchanges (“reciprocals”) that wrote the traditional personal lines business in New York and New Jersey, the surplus notes issued by the New York and New Jersey reciprocals, and the remaining renewal rights to certain other traditional personal lines insurance policies.  The sale of the two attorneys-in-fact and the transfer of the surplus notes triggered deconsolidation of the reciprocals by White Mountains.  OneBeacon and Tower also entered into a Transition Services Agreement (“TSA”), pursuant to which OneBeacon provides certain services to Tower during a three-year term.
OneBeacon received $166.6 million as consideration, which was based upon the carrying value of the traditional personal lines business as of July 1, 2010.  For the year ended December 31, 2010, OneBeacon recorded an after-tax net gain of $24.6 million on the sale that is comprised of $8.5 million included in other revenues and a $16.1 million tax benefit. OneBeacon’s second quarter financial statements included $5.6 million of the tax benefit, which related to the difference between the tax basis of the companies sold as part of the Personal Lines Transaction and the net asset value of those entities under GAAP.  Net written premiums for the business sold were approximately $420.0 million for the year ended December 31, 2009.
 On December 3, 2009, OneBeacon sold the renewal rights to approximately $490.0 million in premiums from its non-specialty commercial lines business to The Hanover Insurance Group (“The Hanover”). The transaction includes small commercial accounts and the non-specialty portion of the middle-market business, beginning with January 1, 2010 effective dates (the “Commercial Lines Transaction”). As consideration for the Commercial Lines Transaction, OneBeacon received $23.2 million, reflected in other revenues.  In accordance with the terms of the Commercial Lines Transaction, during the years ended December 31, 2011 and 2010, OneBeacon was paid additional consideration of $0.8 million and $10.2 million, reflected in other revenues, for aggregate premium renewals exceeding $200.0 million.

NOTE 3. Reserves for Unpaid Losses and Loss Adjustment Expenses

Insurance
White Mountains’ insurance subsidiaries establish loss and LAE reserves that are estimates of amounts needed to pay claims and related expenses in the future for insured events that have already occurred. The process of estimating reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain.
Loss and LAE reserves are typically comprised of (1) case reserves for claims reported and (2) reserves for losses that have occurred but for which claims have not yet been reported, referred to as incurred but not reported (“IBNR”) reserves, which include a provision for expected future development on case reserves. Case reserves are estimated based on the experience and knowledge of claims staff regarding the nature and potential cost of each claim and are adjusted as additional information becomes known or payments are made. IBNR reserves are derived by subtracting paid loss and LAE and case reserves from estimates of ultimate loss and LAE. Actuaries estimate ultimate loss and LAE using various generally accepted actuarial methods applied to known losses and other relevant information. Like case reserves, IBNR reserves are adjusted as additional information becomes known or payments are made.

F-13


Ultimate loss and LAE are generally determined by extrapolation of claim emergence and settlement patterns observed in the past that can reasonably be expected to persist into the future. In forecasting ultimate loss and LAE with respect to any line of business, past experience with respect to that line of business is the primary resource, but cannot be relied upon in isolation. White Mountains’ own experience, particularly claims development experience, such as trends in case reserves, payments on and closings of claims, as well as changes in business mix and coverage limits, is the most important information for estimating its reserves. External data, available from organizations such as statistical bureaus, consulting firms and reinsurance companies, is sometimes used to supplement or corroborate White Mountains’ own experience, and can be especially useful for estimating costs of new business. For some lines of business, such as “long-tail” coverages discussed below, claims data reported in the most recent accident year is often too limited to provide a meaningful basis for analysis due to the typical delay in reporting of claims. For this type of business, White Mountains uses a selected loss ratio method for the initial accident year or years. This is a standard and accepted actuarial reserve estimation method in these circumstances in which the loss ratio is selected based upon information used in pricing policies for that line of business, as well as any publicly available industry data, such as industry pricing, experience and trends, for that line of business.
Uncertainties in estimating ultimate loss and LAE are magnified by the time lag between when a claim actually occurs and when it is reported and settled. This time lag is sometimes referred to as the “claim-tail”. The claim-tail for most property coverages is typically short (usually a few days up to a few months). The claim-tail for liability/casualty coverages, such as automobile liability, general liability, products liability, multiple peril coverage, and workers compensation, can be especially long as claims are often reported and ultimately paid or settled years, even decades, after the related loss events occur. During the long claims reporting and settlement period, additional facts regarding coverages written in prior accident years, as well as about actual claims and trends may become known and, as a result, White Mountains may adjust its reserves. If management determines that an adjustment is appropriate, the adjustment is booked in the accounting period in which such determination is made in accordance with GAAP. Accordingly, should reserves need to be increased or decreased in the future from amounts currently established, future results of operations would be negatively or positively impacted, as applicable.
In determining ultimate loss and LAE, the cost to indemnify claimants, provide needed legal defense and other services for insureds and administer the investigation and adjustment of claims are considered. These claim costs are influenced by many factors that change over time, such as expanded coverage definitions as a result of new court decisions, inflation in costs to repair or replace damaged property, inflation in the cost of medical services and legislated changes in statutory benefits, as well as by the particular, unique facts that pertain to each claim. As a result, the rate at which claims arose in the past and the costs to settle them may not always be representative of what will occur in the future. The factors influencing changes in claim costs are often difficult to isolate or quantify and developments in paid and incurred losses from historical trends are frequently subject to multiple and conflicting interpretations. Changes in coverage terms or claims handling practices may also cause future experience and/or development patterns to vary from the past. A key objective of actuaries in developing estimates of ultimate loss and LAE, and resulting IBNR reserves, is to identify aberrations and systemic changes occurring within historical experience and accurately adjust for them so that the future can be projected reliably. Because of the factors previously discussed, this process requires the use of informed judgment and is inherently uncertain.
White Mountains’ actuaries use several generally accepted actuarial methods to evaluate its loss reserves, each of which has its own strengths and weaknesses. Management places more or less reliance on a particular method based on the facts and circumstances at the time the reserve estimates are made.

F-14


These methods generally fall into one of the following categories or are hybrids of one or more of the following categories:

Historical paid loss development methods:  These methods use historical loss payments over discrete periods of time to estimate future losses. Historical paid loss development methods assume that the ratio of losses paid in one period to losses paid in an earlier period will remain constant. These methods necessarily assume that factors that have affected paid losses in the past, such as inflation or the effects of litigation, will remain constant in the future. Because historical paid loss development methods do not use case reserves to estimate ultimate losses, they can be more reliable than the other methods discussed below that look to case reserves (such as actuarial methods that use incurred losses) in situations where there are significant changes in how case reserves are established by a company’s claims adjusters. However, historical paid loss development methods are more leveraged, meaning that small changes in payments have a larger impact on estimates of ultimate losses, than actuarial methods that use incurred losses because cumulative loss payments take much longer to equal the expected ultimate losses than cumulative incurred amounts. In addition, and for similar reasons, historical paid loss development methods are often slow to react to situations when new or different factors arise than those that have affected paid losses in the past.
 
Historical incurred loss development methods:  These methods, like historical paid loss development methods, assume that the ratio of losses in one period to losses in an earlier period will remain constant in the future. However, instead of using paid losses, these methods use incurred losses (i.e., the sum of cumulative historical loss payments plus outstanding case reserves) over discrete periods of time to estimate future losses. Historical incurred loss development methods can be preferable to historical paid loss development methods because they explicitly take into account open cases and the claims adjusters’ evaluations of the cost to settle all known claims. However, historical incurred loss development methods necessarily assume that case reserving practices are consistently applied over time. Therefore, when there have been significant changes in how case reserves are established, using incurred loss data to project ultimate losses can be less reliable than other methods.

Expected loss ratio methods:  These methods are based on the assumption that ultimate losses vary proportionately with premiums. Expected loss ratios are typically developed based upon the information used in pricing, and are multiplied by the total amount of premiums written to calculate ultimate losses. Expected loss ratio methods are useful for estimating ultimate losses in the early years of long-tailed lines of business, when little or no paid or incurred loss information is available.

Adjusted historical paid and incurred loss development methods:  These methods take traditional historical paid and incurred loss development methods and adjust them for the estimated impact of changes from the past in factors such as inflation, the speed of claim payments or the adequacy of case reserves. Adjusted historical paid and incurred loss development methods are often more reliable methods of predicting ultimate losses in periods of significant change, provided the actuaries can develop methods to reasonably quantify the impact of changes.

White Mountains performs an actuarial review of its recorded reserves each quarter. White Mountains’ actuaries compare the previous quarter’s estimates of paid loss and LAE, case reserves and IBNR to amounts indicated by actual experience. Differences between previous estimates and actual experience are evaluated to determine whether a given actuarial method for estimating loss and LAE should be relied upon to a greater or lesser extent than it had been in the past. While some variance is expected each quarter due to the inherent uncertainty in loss and LAE, persistent or large variances would indicate that prior assumptions and/or reliance on certain reserving methods may need to be revised going forward.
The actuarial analysis is a primary consideration for management in determining its best estimate of loss and LAE reserves. In making its best estimate, management also considers other qualitative factors that may lead to a difference between its best estimate of loss and LAE reserves and the actuarial point estimate. Typically, these factors exist when management and the company’s actuaries conclude that there is insufficient historical incurred and paid loss information or that trends included in the historical incurred and paid loss information are unlikely to repeat in the future. These factors may include, among others, changes in the techniques used to assess underwriting risk, more accurate and detailed levels of data submitted with reinsurance applications, the uncertainty of the current reinsurance pricing environment, the level of inflation in loss costs, changes in ceding company reserving practices, and legal and regulatory developments.

Reinsurance
Sirius Group establishes loss and LAE reserves that are estimates of future amounts needed to pay claims and related expenses for events that have already occurred. Sirius Group also obtains reinsurance whereby another reinsurer contractually agrees to indemnify White Mountains for all or a portion of the reinsurance risks underwritten by White Mountains. Such arrangements, where one reinsurer provides reinsurance to another reinsurer, are usually referred to as “retrocessional reinsurance” arrangements. White Mountains establishes estimates of amounts recoverable from retrocessional reinsurance in a manner consistent with the loss and LAE liability associated with reinsurance contracts offered to its customers (the “ceding companies”), net of an allowance for uncollectible amounts. Net reinsurance loss reserves represent loss and LAE reserves reduced by retrocessional reinsurance recoverable on unpaid losses.
The estimation of net reinsurance loss and LAE reserves is subject to the same risk as the estimation of insurance loss and LAE reserves. In addition to those risk factors which give rise to inherent uncertainties in establishing insurance loss and LAE reserves, the inherent uncertainties of estimating such reserves are even greater for the reinsurer, due primarily to: (1) the claim-tail for reinsurers being further extended because claims are first reported to the original primary insurance company and then through one or more intermediaries or reinsurers, (2) the diversity of loss development patterns among different types of reinsurance treaties or facultative contracts, (3) the necessary reliance on the ceding companies for information regarding reported claims and (4) the differing reserving practices among ceding companies.
As with insurance reserves, the process of estimating reinsurance reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain. Based on the above, such uncertainty may be larger relative to the reserves for a company that principally writes reinsurance compared to an insurance company, and certainty may take a longer time to emerge.
Upon notification of a loss from an insured (typically a ceding company), Sirius Group establishes case reserves, including LAE reserves, based upon Sirius Group’s share of the amount of reserves established by the insured and Sirius Group’s independent evaluation of the loss. In cases where available information indicates that reserves established by a ceding company are inadequate, Sirius Group establishes case reserves or IBNR in excess of its share of the reserves established by the ceding company.  Also, in certain instances, Sirius Group may decide not to establish case reserves or IBNR, when the information available indicates that reserves established by ceding companies are not adequately supported. In addition, specific claim information reported by insureds or obtained through claim audits can alert management to emerging trends such as changing legal interpretations of coverage and liability, claims from unexpected sources or classes of business, and significant changes in the frequency or severity of individual claims where customary. Generally, ceding company audits are not customary outside the United States. This information is often used to supplement estimates of IBNR.
Although loss and LAE reserves are initially determined based on underwriting and pricing analyses, Sirius Group regularly reviews the adequacy of its recorded reserves by using a variety of generally accepted actuarial methods, including historical incurred and paid loss development methods. If actual loss activity differs substantially from expectations, an adjustment to recorded reserves may be warranted. As time passes, loss reserve estimates for a given year will rely more on actual loss activity and historical patterns than on initial assumptions based on pricing indications.
The actuarial methods described above are used to calculate a point estimate of loss and LAE reserves for each company within Sirius Group. These point estimates are then aggregated to produce an actuarial point estimate for the entire segment. Once a point estimate is established, Sirius Group’s actuaries estimate loss reserve ranges to measure the sensitivity of the actuarial assumptions used to set the point estimates. These ranges are calculated from historical variations in loss ratios, payment and reporting patterns by class and type of business.

Loss and LAE development —2012
During the year ended December 31, 2012, White Mountains experienced $41.9 million of net favorable loss reserve development, which consisted of $7.4 million of net favorable loss reserve development at OneBeacon and $34.5 million of net favorable loss reserve development at Sirius Group.
During 2012, OneBeacon experienced $7.4 million of net favorable loss and LAE reserve development on prior accident year reserves. The favorable reserve development at OneBeacon was primarily from workers' compensation, multiple peril liability and general liability lines. This favorable development was offset somewhat by adverse development on excess property claims.
In 2012, Sirius Group had net favorable loss reserve development of $34.5 million. The major reductions in loss reserve estimates at Sirius Group were recognized in casualty runoff ($31.5 million), property ($28.4 million), marine/energy ($11.6 million), trade credit ($6.8 million) and aviation/space ($5.3 million) lines, partially offset by a $46.4 million increase in asbestos loss reserves and a $4.3 million increase in accident and health.


F-17


Loss and LAE development —2011
During the year ended December 31, 2011, White Mountains experienced $76.7 million of net favorable loss reserve development, which consisted of $29.8 million of net favorable loss and LAE reserve development on prior accident year loss reserves at OneBeacon and $46.9 million of net favorable loss reserve development at Sirius Group.
OneBeacon’s net favorable loss and LAE reserve development was primarily due to lower than expected severity on non catastrophe losses related to professional liability lines, multiple peril liability lines and other general liability lines. With respect to the favorable loss reserve development in specialty insurance operations, at December 31, 2010, management had revised its expectations downward for future loss emergence in the professional liability business, which had initially been based on market analysis when this business was initiated in 2002 and 2003. However, during 2011, losses continued to be significantly lower than these revised expectations. As a result, management lowered its selected reserves on the earliest years which affected more recent years as total loss expectations for those years are based in part on prior years’ results. The impact of this revised estimate was a decrease to professional liability reserves of $11.5 million.
During 2010, management began separately reviewing loss reserves for some business which had been previously managed as a part of OneBeacon’s former commercial lines underwriting unit. As of December 31, 2010, the reserves for these businesses had been selected based on expected emergence that was based on the historic loss development of former commercial lines underwriting unit. However, during 2011 the actual emerged experience for these businesses was
significantly lower than the expected emergence. As a result of this favorable emergence, management lowered the loss
reserves for these businesses by $14.0 million during 2011.
In addition to the development described for the lines of business above, OneBeacon also recorded a $4.3 million net decrease in reserves in other lines of business as a result of its review of loss reserves at December 31, 2011.
The net favorable loss reserve development at Sirius Group was primarily attributable to $41.2 million of favorable development on property lines including, $13.1 million of loss reserve reductions for the 2010 Chile earthquake, partially offset by asbestos and environmental increases of $12.3 million.

Loss and LAE development —2010
During the year ended December 31, 2010, White Mountains experienced $93.1 million of net favorable loss reserve development, which consisted of $36.0 million of net favorable loss and LAE reserve development on prior accident year loss reserves at OneBeacon and $57.1 million of net favorable loss reserve development at Sirius Group.
OneBeacon’s net favorable loss reserve development was primarily due to lower than expected severity on non-catastrophe losses related to professional liability lines, multiple peril liability lines and other general liability lines, as well as development on personal lines business. The favorable development also included a $7.5 million release of commercial catastrophe reserves associated with storms occurring in 2004 and 2005.
Specifically, at December 31, 2009, management had revised its expectations downward with respect to future loss emergence in the professional liability business, which had initially been based on market analysis when this business was initiated in 2002 and 2003. However, during 2010, losses continued to be significantly lower than these revised expectations. As a result, management lowered its selected reserves on the earliest years which affected more recent years as total loss expectations for those years are based in part on prior years’ results. The impact of this revised estimate was a decrease to professional liability reserves of $19.3 million.
At December 31, 2009, OneBeacon had recorded $7.5 million of reserves for certain claims related to catastrophes from accident years 2004 and 2005 related to OneBeacon’s excess property business. During 2010, these claims were resolved for amounts below OneBeacon’s policy coverage therefore the reserves were no longer necessary.
In addition to the development described for the lines of business above, OneBeacon also recorded a $9.2 million net decrease in IBNR in other lines of business, primarily personal lines, as a result of its review of loss reserves at December 31, 2010.
The net favorable loss reserve development at Sirius Group was primarily related to short-tailed lines, such as property, accident and health and marine, in recent underwriting years. Included in the $57.1 million favorable loss reserve development was the recognition of $16.3 million in deferred gains from a retrocessional reinsurance contract that incepted in 2000 and was fully collected in 2010.

Fair value adjustment to loss and LAE reserves
In connection with purchase accounting for acquisitions, White Mountains is required to adjust loss and LAE reserves and the related reinsurance recoverables to fair value on their respective acquired balance sheets.  The net reduction to loss and LAE reserves is being recognized through an income statement charge ratably with and over the period the claims are settled.
White Mountains recognized $10.6 million, $8.3 million and $8.5 million of such charges, recorded as loss and LAE during 2012, 2011 and 2010. As of December 31, 2012, the pre-tax un-accreted adjustment was $5.7 million.

F-18


Asbestos and Environmental Loss and Loss Adjustment Expense Reserve Activity
White Mountains’ reserves include provisions made for claims that assert damages from asbestos and environmental related exposures. Asbestos claims relate primarily to injuries asserted by those who came in contact with asbestos or products containing asbestos. Environmental claims relate primarily to pollution and related clean-up cost obligations, particularly as mandated by U.S. federal and state environmental protection agencies. In addition to the factors described above regarding the reserving process, White Mountains estimates its A&E reserves based upon, among other factors, facts surrounding reported cases and exposures to claims, such as policy limits and deductibles, current law, past and projected claim activity and past settlement values for similar claims, as well as analysis of industry studies and events, such as recent settlements and asbestos-related bankruptcies. The cost of administering A&E claims, which is an important factor in estimating loss reserves, tends to be higher than in the case of non-A&E claims due to the higher legal costs typically associated with A&E claims.
Substantially all of OneBeacon's reserves for unpaid loss and LAE for asbestos and environmental exposures relates to discontinued operations (see Note 20). As of December 31, 2012, the remaining unpaid loss and LAE loss reserves for asbestos and environmental exposures related to continuing operations is less than $1.0 million on both a gross and net basis at December 31, 2012.
In 2012, Sirius Group increased its net A&E exposure through two incoming runoff portfolios acquired by White Mountains Solutions. These acquisitions added $11.0 million in net asbestos reserves and $0.7 million in net environmental reserves.
The acquisition of companies having modest portfolios of A&E exposure has been typical of several prior White Mountains Solutions transactions and is likely to be an element of at least some future acquisitions. However, the acquisitions of new A&E liabilities is undertaken only after careful due diligence and utilizing conservative reserving assumptions in relation to industry benchmarks. In the case of those portfolios acquired during 2012, the exposures arise almost entirely from old assumed reinsurance contracts having small limits of liability.
In addition to the $11.0 million increase in asbestos reserves from the two incoming portfolios acquired by White Mountains Solutions mentioned above, Sirius Group recorded $46.4 million and $10.3 million of asbestos-related incurred losses and LAE on its already existing asbestos reserves in 2012 and 2011, respectively.  In the first six months of 2012, Sirius Group increased net asbestos reserves by $12.0 million in response to its quarterly monitoring of newly reported claims. Based on the monitoring trends noted in the first six months 2012, Sirius Group conducted an in-depth analysis of its asbestos exposure, which was completed in third quarter. The main focus of the analysis was on the internal claims analysis of all treaty and facultative contracts likely to have asbestos exposure.  An external expert with extensive asbestos claims experience was utilized to enhance the review.  This analysis entailed examining total expected asbestos losses and LAE from a variety of information sources, including previous asbestos studies, reported client data and external benchmarking scenarios.  The analysis resulted in a net asbestos loss reserve increase of $33.0 million recognized in third quarter. An additional $2.0 million of asbestos losses were recognized in fourth quarter 2012. The 2011 incurred losses were primarily the result of management's monitoring of a variety of metrics including: actual paid and reported claims activity; net survival ratios; peer comparisons; and industry benchmarks.
Offsetting the $0.7 million increase in environmental reserves mentioned above, Sirius Group recorded a decrease of $0.5 million in 2012 of environmental-related losses on its already existing reserves in 2012. In 2011, Sirius Group recorded $2.0 million of environmental losses.
Sirius Group’s net reserves for A&E losses were $189.4 million and $162.7 million at December 31, 2012 and 2011, respectively. Sirius Group’s A&E three-year net loss paid survival ratio was approximately 9.0 years and 11.1 years at December 31, 2012 and 2011. The decrease in the paid survival ratio in 2012 was driven by an unusually high net paid loss of $8.5 million made in first quarter 2012 to commute one of Sirius Group's top five asbestos exposures.
White Mountains’ reserves for A&E losses at December 31, 2012 represent management’s best estimate of its ultimate liability based on information currently available. However, as case law expands, and medical and clean-up costs increase and industry settlement practices change, White Mountains may be subject to asbestos and environmental losses beyond currently estimated amounts. White Mountains cannot reasonably estimate at the present time loss reserve additions arising from any such future adverse developments and cannot be sure that allocated loss reserves, plus the remaining capacity under the NICO Cover and other reinsurance contracts, will be sufficient to cover additional liability arising from any such adverse developments.

NOTE 4. Third-Party Reinsurance

In the normal course of business, White Mountains’ insurance and reinsurance subsidiaries may seek to limit losses that may arise from catastrophes or other events by reinsuring with third-party reinsurers. White Mountains remains liable for risks reinsured in the event that the reinsurer does not honor its obligations under reinsurance contracts. The effects of reinsurance on White Mountains’ insurance and reinsurance subsidiaries’ written and earned premiums and on losses and LAE were as follows:

OneBeacon
In the normal course of its business, OneBeacon purchases reinsurance from high-quality, highly rated, third-party reinsurers in order to minimize loss from large losses or catastrophic events.
The timing and size of catastrophe losses are unpredictable and the level of losses experienced in any year could be material to OneBeacon’s operating results and financial position. Examples of catastrophes include losses caused by earthquakes, wildfires, hurricanes and other types of storms and terrorist acts. The extent of losses caused by catastrophes is a function of the amount and type of insured exposure in the area affected by the event as well as the severity of the event. OneBeacon uses models (primarily AIR Worldwide (“AIR”) Version 12) to estimate the probability of the occurrence of a catastrophic event as well as potential losses under various scenarios. OneBeacon uses this model output in conjunction with other data to manage its exposure to catastrophe losses through individual risk selection and by limiting its concentration of insurance written in catastrophe-prone areas such as coastal regions. In addition, OneBeacon imposes wind deductibles on
existing coastal windstorm exposures.
Since the terrorist attacks of September 11, 2001, OneBeacon has sought to mitigate the risk associated with any future terrorist attacks by limiting the aggregate insured value of policies in geographic areas with exposure to losses from terrorist attacks. This is accomplished by either limiting the total insured values exposed, or, where applicable, through the use of terrorism exclusions.
In December 2007, the U.S. government extended the Terrorism Risk Insurance Act of 2002 (the “Terrorism Act” or “TRIA”) until December 31, 2014. The Terrorism Act established a federal “backstop” for commercial property and casualty losses, including workers compensation, resulting from acts of terrorism by or on behalf of any foreign person or foreign interest. As extended, the law now also covers domestic acts of terrorism. The law limits the industry’s aggregate liability by requiring the federal government to share 85% of certified losses once a company meets a specific retention or deductible as determined by its prior year’s direct written premiums and limits the aggregate liability to be paid by the government and industry without further action by Congress at $100.0 billion. In exchange for this “backstop,” primary insurers are required to make coverage available to commercial insureds for losses from acts of terrorism as specified in the Terrorism Act. The following types of coverage are excluded from the program: commercial automobile, burglary and theft, surety, farmowners multi-peril and all professional liability coverage except directors and officers coverage.
OneBeacon estimates its individual retention level for commercial policies subject to the Terrorism Act to be approximately $100.0 million in 2013, which is based on 2012 net written premiums. The federal government will pay 85% of covered terrorism losses that exceed OneBeacon’s or the industry’s retention levels in 2013 up to a total of $100.0 billion.
OneBeacon seeks to further reduce its potential loss from catastrophe exposures through the purchase of catastrophe reinsurance. Effective May 1, 2012, OneBeacon renewed its property catastrophe reinsurance program through April 30, 2013. The program provides coverage for OneBeacon’s property business as well as certain acts of terrorism. Under the program, the first $25.0 million of losses resulting from any single catastrophe are retained and the next $155.0 million of losses resulting from the catastrophe are reinsured in three layers, although OneBeacon retains a co-participation of 55% of losses from $25.0 million to $40.0 million, 15% of losses from $40.0 million to $80.0 million and 10% of losses from $80.0 million to $180.0 million. Thus, for a $180.0 million loss, OneBeacon would retain $49.3 million. Any loss above $180.0 million would be retained in full. In the event of a catastrophe, OneBeacon’s property catastrophe reinsurance program is reinstated for the remainder of the original contract term by paying a reinstatement premium that is based on the percentage of coverage reinstated and the original property catastrophe coverage premium. This $180.0 million limit was reduced from the $225.0 million limit that OneBeacon’s previous catastrophe reinsurance program provided, as a result of lower catastrophe exposure as a specialty-focused company. As a result of hurricane Sandy in October 2012, OneBeacon recorded ceded losses of $15.6 million and reinstatement premiums of $1.9 million related to this treaty.
In addition to the corporate catastrophe reinsurance protection that it secures, OneBeacon may also purchase dedicated reinsurance protection for specific businesses. In 2012, OneBeacon purchased insurance to protect its collector cars and boats business from catastrophic losses. This treaty covered losses in excess of $2.5 million up to $25.0 million in two layers. The first layer, $2.5 million in excess of $2.5 million, carried a 5% co-participation. The company had a 20% co-participation on the second layer, $20.0 million in excess of $5 million. Catastrophe losses above $25.0 million are retained by the company in full. Reinstatement premiums are paid if the coverage is attached. As a result of hurricane Sandy in October 2012, OneBeacon recorded ceded losses of $11.9 million and reinstatement premiums of $1.4 million related to this treaty.
OneBeacon also purchased a per-occurrence treaty for its Inland Marine Underwriters business (“IMU”) that protects against large occurrences, whether a single large claim or a catastrophe. The IMU treaty attaches at $2.0 million per occurrence. Coverage is provided up to $60.0 million. The first layer of the marine treaty is $5.0 million in excess of $2.0 million, with an annual aggregate deductible of $1.5 million for large losses and $5.0 million for catastrophes losses. For losses in the layer $10.0 million excess of $50.0 million, the company retains half of the loss. The portion of loss above $60.0 million is retained in full by the company. Reinstatement premiums are paid in full or in part depending on the layer and the occurrence if the coverage is attached. As a result of hurricane Sandy in October 2012, OneBeacon recorded ceded loss of $41.0 million and reinstatement premiums of $5.4 million related to this treaty. Losses retained under both the collector cars and boats and marine reinsurance treaties are subject to the corporate catastrophe treaty.

F-22


Through June 30, 2010 OneBeacon ceded $25.6 million of written premiums from its Northeast homeowners business written through OneBeacon Insurance Company (“OBIC”) and its subsidiary companies, along with Adirondack and New Jersey Skylands Insurance Association.  Effective July 1, 2010, the closing date of the Personal Lines Transaction, the agreement was amended to remove OneBeacon as a signatory. 
OneBeacon’s property catastrophe reinsurance program does not cover property losses resulting from any nuclear events or biological, chemical or radiological terrorist attacks or losses resulting from acts of terrorism as defined under the Terrorism Act, as amended, committed by an individual or individuals acting on behalf of any foreign person or foreign interest, as well as domestic acts of terrorism. Such losses are subject to coverage provided to insurance companies by TRIA.
 OneBeacon also purchases property-per-risk reinsurance coverage to reduce large loss volatility. The property-per-risk reinsurance program reinsures losses in excess of $10.0 million up to $100.0 million. Individual risk facultative reinsurance may be purchased above $100.0 million where OneBeacon deems it appropriate. Under the property-per-risk program, OneBeacon retains a co-participation of 10% for losses in excess of $20.0 million up to $50.0 million and a co-participation of 20% for losses in excess of $50.0 million. The property-per-risk treaty also provides one limit of reinsurance protection for losses in excess of $10.0 million up to $100.0 million on an individual risk basis for terrorism losses. However, any nuclear events, or biological, chemical or radiological terrorist attacks are not covered.
OneBeacon also maintains a casualty reinsurance program that provides protection for individual policies involving general liability, automobile liability, professional liability or umbrella liability. OneBeacon's healthcare professional liability treaty covers losses in excess of $5.0 million up to $20.0 million in two layers. The first layer, $5.0 million excess of $5.0 million has a 20% co-participation. All other casualty business is covered in a separate treaty covering losses in excess of $5.0 million up to $21.0 million. This treaty has a 22.5% co-participation in the first layer ($6.0 million excess of $5.0 million) and a 10% co-participation in the second layer of $10.0 million excess of $11.0 million. OneBeacon purchases a treaty to protect against large workers compensation losses that covers 100% of the loss in excess of $1.0 million up to $10.0 million per person. In addition, for casualty losses involving more than one insured, OneBeacon maintains a dedicated treaty that covers up to $40.0 million in excess of a $10.0 million retention.
At December 31, 2012, OneBeacon had $3.3 million and $107.3 million of reinsurance recoverables on paid and unpaid losses. Reinsurance contracts do not relieve OneBeacon of its obligation to its policyholders. OneBeacon is selective with its reinsurers, placing reinsurance with only those reinsurers having a strong financial condition. OneBeacon monitors the financial strength of its reinsurers on an ongoing basis. Uncollectible amounts historically have not been significant. As of December 31, 2012, 90% of reinsurance recoverables on paid and unpaid losses are from reinsurers with an A.M. Best rating of A (Excellent, which is the third highest of 16 financial strength ratings) or better. The largest recoverable from an individual reinsurer was $10.1 million with Hannover Ruckversich, which has an A.M. Best Company (“A.M. Best”) ratings of A++ (Superior, which is the highest of 16 financial strength ratings). The reinsurance balances associated with the runoff business are included in discontinued operations (see Note 20).

Sirius Group
Sirius Group's reinsurance protection primarily consists of pro-rata and excess of loss protections to cover aviation, trade credit, and certain property exposures. Sirius Group's proportional reinsurance programs provide protection for part of the non-proportional treaty accounts written in Europe, the Americas, Asia, the Middle East, and Australia.  These reinsurance protections are designed to increase underwriting capacity where appropriate, and to reduce exposure both to large catastrophe losses and to a frequency of smaller loss events.  Attachment points and coverage limits vary by region around the world. In addition to its proportional reinsurance, Sirius Group also purchases excess of loss reinsurance protection for $15.0 million in excess of a retention of $5.0 million for the facultative and direct property portfolios written by the Stockholm, Hamburg and London branches (excluding business written in the United States).  For the facultative and direct property portfolios written by the Hamburg and Stockholm branches, an additional $15.0 million of reinsurance protection in excess of the $20.0 million coverage has been purchased for 2013. Sirius Group also has $5.0 million of protection in excess of a retention of $5.0 million for the London branch for facultative and direct U.S.-catastrophe exposed business (excluding Florida risks), which was renewed through June 30, 2013. As a result of hurricane Sandy in October 2012, Sirius Group recognized a full $5.0 million recovery on this account.
In 2012, 2011 and 2010, Sirius Group has had in place group excess of loss retrocessional coverage for its non-U.S. and non-Japan earthquake-related exposures. This cover was renewed for one year at April 1, 2012, providing $17.0 million of reinsurance protection through partially placed coverage of a $40.0 million layer in excess of Sirius Group's retention of
$35.0 million. In addition, Sirius Group purchased two industry loss warranty (“ILW”) contracts that provide $10.0 million of coverage for a first event non-U.S. and non-Japan earthquake loss at a market loss event of $7.5 billion or more, with $5.0 million of additional coverage for a second market loss event at this level. Sirius Group also has $37.5 million of New Madrid earthquake ILW coverage through March 2013 that provides reinsurance protection both on a first and second market event of $20.0 billion.

F-23


In addition, Sirius Group has an ILW providing $5.0 million of coverage for a first loss European windstorm and flood at a market loss event of $5.0 billion, which expires March 2013. During the fourth quarter 2012, additional ILW protections providing $40.0 million of reinsurance coverage were purchased at different market loss levels for wind, flood, and all natural perils in Europe or Scandinavia, with the majority of these covers expiring in March 2013.
As of December 31, 2012, losses incurred for the February 2011 New Zealand earthquake totaled $47.0 million, $2.0 million of which was covered by Sirius Group’s non-U.S. and non-Japan earthquake coverage.  During 2010, as a result of the Chile Earthquake in February 2010, Sirius Group recovered $65.0 million under its non-U.S. and non-Japan earthquake coverage, which was a full limit loss.
Sirius Group's aviation reinsurance program is intended to reduce exposure to a frequency of small losses, a single large loss, or a combination of both.  In 2013, for the proportional and facultative aviation portfolios, reinsurance protection purchases were generally for coverage on losses from events that cause a market loss in excess of $150.0 million up to a full airline policy limit of $2.25 billion, including clash coverage. This program is in effect through November 2013. For the non-proportional aviation portfolio, reinsurance protection includes a 15% quota share treaty. In addition, the non-proportional portfolio is protected by $33.0 million in the form of first event ILWs, and $5.0 million of available limit in the form of second event ILWs. The first event ILWs attach at industry loss levels between $400.0 million and $1.0 billion.  The majority of the reinsurance protections, excluding ILWs, include a reinstatement of the cover in case of loss.
For the marine yacht portfolio written by the London branch, reinsurance coverage is in place for $9.8 million in excess of a retention of $0.3 million.
For accident and health, Sirius Group has excess of loss protection covering personal accident and life of €10.0 million ($13.0 million based on the December 31, 2012 EUR to USD exchange rate) of protection in excess of a €5.0 million ($7.0 million based on the December 31, 2012 EUR to USD exchange rate) retention for the Stockholm, Hamburg, Liege and Singapore branches.
For 2012, Sirius Group ceded 20% and 50% of its trade credit and bond business, respectively, under a quota share retrocession, which supported growth in this line.  The treaty was renewed for 2013.
Almost all of Sirius Group's excess of loss reinsurance protections, excluding ILWs, include provisions that reinstate coverage at a cost of 100% or more of the original reinsurance premium.
At December 31, 2012, Sirius Group had $14.6 million of reinsurance recoverables on paid losses and $321.8 million of reinsurance recoverables on unpaid losses that will become recoverable if claims are paid in accordance with current reserve estimates. Because retrocessional reinsurance contracts do not relieve Sirius Group of its obligation to its insureds, the collectability of balances due from Sirius Group's reinsurers is critical to its financial strength. Sirius Group monitors the financial strength and ratings of retrocessionaires on an ongoing basis.

F-28


Fair value measurements at December 31, 2012
White Mountains used quoted market prices or other observable inputs to determine fair value for the 95.0% of its investment portfolio. Investments valued using Level 1 inputs include fixed maturity investments, primarily investments in U.S. Treasuries, common equities and short-term investments, which include U.S. Treasury Bills. Investments valued using Level 2 inputs consist of fixed maturity investments including corporate debt, state and other governmental debt, convertible fixed maturity securities and mortgage and asset-backed securities. Fair value estimates for investments that trade infrequently and have few or no observable market prices are classified as Level 3 measurements. Level 3 fair value estimates based upon unobservable inputs include White Mountains’ investments in hedge funds and private equity funds, as well as investments in certain debt securities where quoted market prices are unavailable. White Mountains uses brokers and outside pricing services to assist in determining fair values. For investments in active markets, White Mountains uses the quoted market prices provided by outside pricing services to determine fair value. The outside pricing services used by White Mountains have indicated that if no observable inputs are available for a security, they will not provide a price. In those circumstances, White Mountains estimates the fair value using industry standard pricing models and observable inputs such as benchmark interest rates, matrix pricing, market comparables, broker quotes, issuer spreads, bids, offers, credit rating, prepayment speeds and other relevant inputs. White Mountains performs procedures to validate the market prices obtained from the outside pricing sources. Such procedures, which cover substantially all of its fixed maturity investments include, but are not limited to, evaluation of model pricing methodologies and review of the pricing services’ quality control processes and procedures on at least an annual basis, comparison of market prices to prices obtained from different independent pricing vendors on at least a semi-annual basis, monthly analytical reviews of certain prices, and review of assumptions utilized by the pricing service for selected measurements on an ad hoc basis throughout the year. White Mountains also performs back-testing of selected sales activity to determine whether there are any significant differences between the market price used to value the security prior to sale and the actual sale price on an ad-hoc basis throughout the year. Prices provided by the pricing services that vary by more than 5.0% and $1.0 million from the expected price based on these procedures are considered outliers. In circumstances where the results of White Mountains’ review process do not appear to support the market price provided by the pricing services, White Mountains challenges the price. If White Mountains cannot gain satisfactory evidence to support the challenged price, it relies upon its own pricing methodologies to estimate the fair value of the security in question. The fair values of such securities are considered to be Level 3 measurements.
 White Mountains’ investments in debt securities are generally valued using matrix and other pricing models. Key inputs include benchmark yields, benchmark securities, reported trades, issuer spreads, bids, offers, credit ratings and prepayment speeds.  Income on mortgage-backed and asset-backed securities is recognized using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When actual prepayments differ significantly from anticipated prepayments, the estimated economic life is recalculated and the remaining unamortized premium or discount is amortized or accreted prospectively over the remaining economic life.
White Mountains employs a number of procedures to assess the reasonableness of the fair value measurements for its other long-term investments, including obtaining and reviewing the audited annual financial statements of each hedge fund and private equity fund and periodically discussing each fund’s pricing with the fund manager. However, since the fund managers do not provide sufficient information to evaluate the pricing inputs and methods for each underlying investment, the inputs are considered to be unobservable. Accordingly, the fair value of White Mountains’ investments in hedge funds and private equity funds has been classified as Level 3 measurements. The fair value of White Mountains’ investments in hedge funds and private equity funds has been determined using net asset value.
 In addition to the investments described above, White Mountains has $79.7 million and $68.1 million of investment-related liabilities recorded at fair value and included in other liabilities as of December 31, 2012 and December 31, 2011.  These liabilities relate to securities that have been sold short by limited partnerships in which White Mountains has investments and is required to consolidate under GAAP.  All of the liabilities included have a Level 1 designation.

Mortgage-backed, Asset-backed Securities
White Mountains purchases commercial and residential mortgage-backed securities with the goal of maximizing risk adjusted returns in the context of a diversified portfolio. White Mountains’ non-agency commercial mortgage-backed portfolio (“CMBS”) is generally short-term and structurally senior, with more than 25 points of subordination on average for fixed rate CMBS and more than 50 points of subordination on average for floating rate CMBS as of December 31, 2012.  In general, subordination represents the percentage principal loss on the underlying collateral that would be absorbed by other securities lower in the capital structure before the more senior security incurs a loss. White Mountains believes these levels of protection will mitigate the risk of loss tied to the refinancing challenges facing the commercial real estate market.  As of December 31, 2012, on average less than 1.0% of the underlying loans were reported as non-performing for all non-agency CMBS held by White Mountains. White Mountains is not an originator of residential mortgage loans and did not hold any residential mortgage-backed securities (“RMBS”) categorized as sub-prime as of December 31, 2012. White Mountains’ investments in hedge funds and private equity funds contain negligible amounts of sub-prime mortgage-backed securities at December 31, 2012. White Mountains considers sub-prime mortgage-backed securities as those that have underlying loan pools that exhibit weak credit characteristics, or those that are issued from dedicated sub-prime shelves or dedicated second-lien shelf registrations (i.e., White Mountains considers investments backed primarily by second-liens to be sub-prime risks regardless of credit scores or other metrics).

F-32


White Mountains categorizes mortgage-backed securities as “non-prime” (also called “Alt A” or “A-”) if they are backed by collateral that has overall credit quality between prime and sub-prime based on White Mountains’ review of the characteristics of their underlying mortgage loan pools, such as credit scores and financial ratios. White Mountains’ non-agency residential mortgage-backed portfolio is generally moderate-term and structurally senior. White Mountains does not own any collateralized debt obligations, including residential mortgage-backed collateralized debt obligations.

Certain of the hedge fund investments in which White Mountains is invested are no longer active and are in the process of disposing of their underlying investments. Distributions from such funds are remitted to investors as the fund’s underlying investments are liquidated. At December 31, 2012, distributions of $3.3 million were outstanding from these investments. The actual amount of the final distribution remittances remain subject to market fluctuations. The date at which such remittances will be received is not determinable at December 31, 2012.
White Mountains has also submitted redemption requests for certain of its investments in active hedge funds.  At December 31, 2012, redemptions of $1.9 million are outstanding and are subject to market fluctuations. Redemptions are recorded as receivables when approved by the hedge funds and no longer subject to market fluctuations.
Investments in private equity funds are generally subject to a “lock-up” period during which investors may not request a redemption. Distributions prior to the expected termination date of the fund may be limited to dividends or proceeds arising from the liquidation of the fund’s underlying investments. In addition, certain private equity funds provide an option to extend the lock-up period at either the sole discretion of the fund manager or upon agreement between the fund and the investors.
At December 31, 2012, investments in private equity funds were subject to lock-up periods as follows:

Rollforward of Fair Value Measurements by Level
White Mountains uses quoted market prices where available as the inputs to estimate fair value for its investments in active markets. Such measurements are considered to be either Level 1 or Level 2 measurements, depending on whether the quoted market price inputs are for identical securities (Level 1) or similar securities (Level 2). Level 3 measurements for fixed maturity investments, common equity securities, convertible fixed maturity investments and other long-term investments at December 31, 2012 and 2011 consist of securities for which the estimated fair value has not been determined based upon quoted market price inputs for identical or similar securities.

Fair Value Measurements — transfers between levels
 During 2012, two fixed maturity securities classified as Level 3 measurements in the prior period was recategorized as Level 2 measurements because quoted market prices for similar securities that were considered reliable and could be validated against an alternative source were available at December 31, 2012.  These measurements comprise “Transfers out” of Level 3 and “Transfers in” to Level 2 of $61.8 million for the period ended December 31, 2012. For the year-ended December 31, 2012, “Transfers out” of Level 2 and “Transfers in” to Level 3 fixed maturity investments of $22.1 million consists of one asset-backed security for which the estimated fair value was determined using a single broker quote.
At December 31, 2011, ten fixed maturity securities which had been classified as Level 3 measurements at January 1, 2011 were recategorized as Level 2 measurements because quoted market prices for similar securities that were considered reliable and could be validated against an alternative source were available at December 31, 2011. These measurements comprise “Transfers out” of Level 3 and “Transfers in” to Level 2 of $269.2 million for the period ended December 31, 2011.  One security that was classified as a Level 2 investment at January 1, 2011 was priced with unobservable inputs and represents “Transfers in” of $18.2 million in Level 3 investments.  The fair value of this security was estimated using industry standard pricing models, in which management selected inputs using its best judgment.  The pricing models used by White Mountains use the same valuation methodology for all Level 3 measurements for fixed maturities. The security is considered to be Level 3 because the measurements are not directly observable. At December 31, 2011, the estimated fair value for this security determined using the industry standard pricing models was $1.6 million less than the estimated fair value based upon quoted prices provided by a third party pricing vendor.

2012 OBH Senior Notes
In November 2012, OneBeacon U.S. Holdings, Inc. (“OBH”), an intermediate holding company of OneBeacon, issued $275 million face value of senior unsecured debt (the "2012 OBH Senior Notes") through a public offering, at an issue price of 99.9% and received $272.9 million of proceeds. The 2012 OBH Senior Notes bear an annual interest rate of 4.6% payable semi-annually in arrears on May 9 and November 9, until maturity on November 9, 2022, and are fully and unconditionally guaranteed as to the payment of principal and interest by OneBeacon Ltd.

Taking into effect the amortization of the original issue discount and all underwriting and issuance expenses, the 2012 OBH Senior Notes have an effective yield to maturity of approximately 4.7% per annum.
OBH recorded $1.8 million in interest expense on the 2012 OBH Senior Notes for the year ended December 31, 2012.

2003 OBH Senior Notes
In May 2003, OBH issued $700.0 million face value of senior unsecured debt (the “2003 OBH Senior Notes”) through a public offering, at an issue price of 99.7% and received $693.4 million of proceeds. The 2003 OBH Senior Notes had an annual interest rate of 5.875%, payable semi-annually in arrears on May 15 and November 15, until maturity in May 2013. White Mountains fully and unconditionally guaranteed the payment of principal and interest on the 2003 OBH Senior Notes for a fee equal to 25 basis points per annum on the outstanding principal amount of the 2003 OBH Senior Notes.
OBH incurred $7.3 million in expenses related to the issuance of the 2003 OBH Senior Notes (including $4.5 million in underwriting fees), which were recognized into interest expense over the life of the 2003 OBH Senior Notes. Taking into effect the amortization of the original issue discount and all underwriting and issuance expenses, the 2003 OBH Senior Notes had an effective yield to maturity of approximately 6.0% per annum.  OBH recorded $15.1 million, $20.5 million and $29.5 million in interest expense, inclusive of amortization of issuance costs, on the 2003 OBH Senior Notes for the years ended December 31, 2012, 2011 and 2010.
On June 1, 2010, through a cash tender offer, OBH repurchased and retired $156.4 million aggregate principal amount of 2003 OBH Senior Notes for an aggregate purchase price of $165.4 million, which resulted in a $9.6 million loss, including transaction fees.
In addition to the cash tender offer, during 2010 OBH repurchased and retired $29.7 million of outstanding 2003 OBH Senior Notes for $30.8 million, which resulted in a $1.2 million loss and OBIC purchased $1.1 million of outstanding 2003 OBH Senior Notes for $1.1 million.
On April 6, 2011, through a cash tender offer, OBH purchased and retired $150.0 million aggregate principal amount of 2003 OBH Senior Notes for $161.6 million, which resulted in a $12.0 million loss, including transaction fees.
In December 2012, OBH repurchased the remaining $269.8 million of 2003 OBH Senior Notes for $275.9 million, which resulted in a $6.3 million loss, including transaction fees and the write-off of the remaining $0.2 million in unamortized deferred costs and original issue discount at the time of repurchase, in the year ended December 31, 2012.

SIG Senior Notes
In March 2007, SIG issued $400.0 million face value of senior unsecured notes (“SIG Senior Notes”) at an issue price of 99.715% for net proceeds of $392.0 million after taking into effect both deferrable and non-deferrable issuance costs, including the interest rate lock agreement described below. The SIG Senior Notes were issued in an offering that was exempt from the registration requirements of the Securities Act of 1933. The SIG Senior Notes bear an annual interest rate of 6.375%, payable semi-annually in arrears on March 20 and September 20, until maturity in March 2017.
SIG incurred $3.6 million in expenses related to the issuance of the SIG Senior Notes (including $2.6 million in underwriting fees), which have been deferred and are being recognized into interest expense over the life of the SIG Senior Notes.

F-38


In anticipation of the issuance of the SIG Senior Notes, SIG entered into an interest rate lock agreement to hedge its interest rate exposure from the date of the agreement until the pricing of the SIG Senior Notes. The agreement was terminated on March 15, 2007 with a loss of $2.4 million, which was recorded in other comprehensive income. The loss is being reclassified from accumulated other comprehensive income over the life of the SIG Senior Notes using the interest method and is included in interest expense. At December 31, 2012, the unamortized balance of the loss remaining in accumulated other comprehensive income was $1.2 million.
Taking into effect the amortization of the original issue discount and all underwriting and issuance expenses, including the interest rate lock agreement, the SIG Senior Notes yield an effective rate of approximately 6.5% per annum. White Mountains recorded $26.2 million of interest expense, inclusive of amortization of issuance costs and the interest rate lock agreement, on the SIG Senior Notes for the years ended December 31, 2012, 2011, and 2010.

WTM Bank Facility
On August 12, 2011, White Mountains entered into a revolving credit facility with a total commitment of $375.0 million (the “WTM Bank Facility”) with a syndicate of lenders administered by Bank of America, N.A. that has a maturity date of August 12, 2015. The WTM Bank Facility replaces the previous revolving credit facility which had a total commitment of $475.0 million.  White Mountains recorded $1.7 million, $3.1 million and $1.1 million of interest expense on the WTM Bank Facility for the years ended December 31, 2012, 2011 and 2010.
In December 2012, White Mountains borrowed $150.0 million under the WTM Bank Facility at a blended interest rate of 3.53%. White Mountains repaid $75.0 million in December 2012. As of December 31, 2012, White Mountains had a balance of $75.0 million outstanding under the revolving credit facility, which was fully repaid in January 2013.
The WTM Bank Facility contains various affirmative, negative and financial covenants which White Mountains considers to be customary for such borrowings, including certain minimum net worth and maximum debt to capitalization standards.  Failure to meet one or more of these covenants could result in an event of default, which ultimately could eliminate availability under these facilities and result in acceleration of principal repayment on any amounts outstanding. 

Old Lyme Note
On December 31, 2011 Sirius Group acquired the runoff loss reserve portfolio of Old Lyme (see Note 2).  As part of the acquisition, Sirius Group entered into a five-year $2.1 million purchase note.  The principal amount of the purchase note is subject to upward adjustments for favorable loss reserve development (up to 50% of $6.0 million) and downward adjustments for any adverse loss reserve development.

Sierra Note
In connection with its acquisition of the Sierra Insurance Group Companies (“Sierra Group”) on March 31, 2004, Sirius Group entered into a $62.0 million purchase note (the “Sierra Note”), $58.0 million of which may be adjusted over its six-year term to reflect favorable or adverse loss reserve development on the acquired reserve portfolio and runoff of remaining policies in force (mainly workers compensation business), as well as certain other balance sheet protections. Since inception the principal of the Sierra Note had been reduced by $29.0 million as a result of adverse development on the acquired reserves and runoff of unearned premium, which includes $5.2 million and $22.8 million of adverse development which occurred during 2008 and 2005 and $1.9 million and $9.1 million of favorable development in 2010 and 2007. Interest accrued on the unpaid balance of the Sierra Note at a rate of 4.0% per annum, compounded quarterly, and was payable at its maturity.
On October 31, 2008, White Mountains disposed of its remaining interest in the Sierra Group as part of the Berkshire Exchange transaction. White Mountains was still obligated to repay the Sierra Note, but Berkshire provided White Mountains an indemnity, whereby Berkshire reimbursed White Mountains all amounts due under the Sierra Note at its maturity, as adjusted for future reserve development, except for the portion of interest on the Sierra Note that accrued from its issue date through December 31, 2007, plus interest on this accrued amount through the date of repayment.
The Sierra Note matured on March 31, 2010.  However, the final amount due was in dispute with respect to the amount of loss reserve development.  On September 15, 2010, White Mountains paid Sierra the undisputed amounts owed of $42.8 million on the Sierra Note which consisted of $33.0 million for the principal repayment and $9.8 million for accrued interest.  Berkshire reimbursed White Mountains $36.7 million, which consisted of the $33.0 million principal balance and $3.7 million for accrued interest.
During the fourth quarter of 2011, the dispute was settled through arbitration.  White Mountains paid additional interest accrued on the Sierra Note and recognized $5.5 million of interest expense.

Atlantic Specialty Note
In connection with its acquisition of Atlantic Specialty Insurance Company on March 31, 2004, OneBeacon issued a $20.0 million ten-year note to the seller (the “Atlantic Specialty Note”). The note accrued interest at a rate of 5.2%, except that the outstanding principal amount in excess of $15.0 million accrued interest at a rate of 3.6%. In 2010, OneBeacon repaid the remaining $14.0 million outstanding principal on the note.

In 2012, new tax legislation was enacted in Sweden, which was effective January 1, 2013, that reduces the corporate tax rate from 26.3% to 22.0%. This resulted in a reduction of $65.4 million in Sirius Group’s deferred tax liabilities in Sweden.
The non-U.S. component of pre-tax income was $250.0 million, $65.4 million and $74.4 million for the years ended December 31, 2012, 2011 and 2010.

Tax Payments and Receipts
Net income tax payments to (receipts from) national governments (primarily the United States) totaled $17.5 million, $12.5 million, and $(47.0) million for the years ended December 31, 2012, 2011 and 2010.

Deferred Tax Inventory
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts for tax purposes.

White Mountains’ deferred tax assets are net of U.S. federal, state, and non-U.S. valuation allowances and, to the extent they relate to non-U.S. jurisdictions, they are shown at year-end exchange rates.

Valuation Allowance
White Mountains records a valuation allowance against deferred tax assets if it becomes more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in valuation allowances from period to period are included in income tax expense in the period of change. In determining whether or not a valuation allowance, or change therein, is warranted, White Mountains considers factors such as prior earnings history, expected future earnings, carryback and carryforward periods and strategies that if executed would result in the realization of a deferred tax asset.  It is possible that certain planning strategies or projected earnings in certain subsidiaries may not be feasible to utilize the entire deferred tax asset, which could result in material changes to White Mountains' deferred tax assets and tax expense.

F-41


Of the $254.0 million valuation allowance at December 31, 2012, $192.0 million relates to deferred tax assets on net operating losses in Luxembourg subsidiaries (discussed below under “Net Operating Loss and Capital Loss Carryforwards”) and $62.0 million relates to deferred tax assets on U.S. losses and other federal deferred tax benefits.  Of the $232.6 million valuation allowance at December 31, 2011, $225.5 million relates to deferred tax assets on net operating losses in Luxembourg subsidiaries (discussed below under “Net Operating Loss and Capital Loss Carryforwards”) and $6.9 million relates to deferred tax assets on U.S. losses and other federal deferred tax benefits.

Luxembourg
During the fourth quarters of 2012 and 2011, White Mountains recorded net tax benefits of $41.3 million and $129.5 million from the net release of valuation allowances against deferred tax assets in Luxembourg-domiciled subsidiaries.  These companies had built up substantial deferred tax assets due to net operating loss carryforwards (“NOLs”).  The loss carryforwards primarily relate to tax deductible write downs in 2007 and 2008 of investments in U.S. subsidiaries. There were partial valuation allowances on these deferred tax assets in periods prior to the fourth quarter of 2012 and 2011 because the companies did not expect sufficient future taxable income to utilize them.
During the fourth quarter of 2012 and 2011, Sirius Group undertook a series of reorganizations to optimize operational and capital efficiency.  As part of the reorganizations, investments and outstanding internal debt instruments were contributed to Luxembourg-domiciled subsidiaries with net operating loss carryforwards. One of the companies, S.I. Holdings (Luxembourg) S.à r.l., (“SI Holdings”) (formerly OneBeacon Holdings (Luxembourg) S.à r.l.), was acquired from OneBeacon on January 24, 2012.  As the plan for the Sirius Group to acquire SI Holdings and contribute the notes was in place on December 31, 2011, and this was a transaction between entities under common control, White Mountains accounted for the tax effects of the transaction as if it had occurred in 2011. An investment portfolio was contributed to SI Holdings in January 2013, pursuant to a plan in place on December 31, 2012, that will generate income utilizing the deferred tax asset over an extended period of time. The deferred tax assets for the remaining NOLs at the companies are offset by a valuation allowance as no additional taxable income is expected.

United States
During the fourth quarter 2012, White Mountains recorded tax expense of $37.8 million to establish a valuation allowance against deferred tax assets of Guilford Holdings, Inc. and subsidiaries (“Guilford”), as White Mountains management determined that the strategies supporting the deferred tax assets were no longer feasible to utilize the assets.  Guilford consists of service companies that are included in the Other Operations segment.
During the fourth quarter 2012, White Mountains recorded tax expense of $3.9 million to establish a valuation allowance against deferred tax assets related to foreign tax credit carryforwards at Sirius Re Holdings, Inc. and subsidiaries (“SRHI”) that expire in 2016 and 2017. SRHI is no longer expected to generate sufficient taxable income to utilize these credits. SRHI has an additional $4.6 million of foreign tax credits that expire in 2018-2022 that are still expected to be utilized.
During 2012, White Mountains recorded tax expense of $13.7 million to establish valuation allowances against deferred tax assets of BAM and Houston General Insurance Exchange (“Houston General Insurance”) as it is uncertain if these companies will have sufficient taxable income to utilize their deferred tax assets. However, since BAM and Houston General Insurance are mutual insurance companies that are owned by their members, their results do not affect White Mountains’ common shareholders’ equity as they are attributable to non-controlling interests.

White Mountains expects to utilize net operating loss carryforwards in Luxembourg of $1,308.5 million but does not expect to utilize the remainder as they belong to companies that are not expected to have sufficient income in the future.  These losses primarily relate to tax deductible write-downs in 2007 and 2008 of investments in U.S. subsidiaries held by Luxembourg subsidiaries.  Included in the U.S. net operating loss carryforwards are losses of $29.0 million subject to an annual limitation on utilization under Internal Revenue Code Section 382.  At December 31, 2012, there were U.S. foreign tax credit carryforwards available of $10.6 million, which begin to expire in 2016.  As discussed above, a deferred tax valuation allowance of $3.9 million has been established for these credits. At December 31, 2012, there were U.S. low-income housing tax credit carryforwards available of $4.8 million, which begin to expire in 2031.  At December 31, 2012, there were U.S. investment tax credit carryforwards available of $0.2 million, which begin to expire in 2031. Also, at December 31, 2012, there were U.S. alternative minimum tax credit carryforwards of $1.5 million which do not expire.
During 2010, White Mountains International S.à r.l. (“WMI”) received a tax ruling in Luxembourg which allowed it to change its tax functional currency in Luxembourg to the Swedish krona from the euro.  Pursuant to the ruling, WMI revalued its NOL carryforwards in Luxembourg using the December 31, 2008 euro/krona exchange rate.  This resulted in WMI recording an $11.9 million deferred tax benefit in 2010 for the increase in its NOLs in Luxembourg.

Uncertain Tax Positions
Under ASC 740-10, recognition of the benefit of a given tax position is based upon whether a company determines that it is more likely than not that a tax position will be sustained upon examination based upon the technical merits of the position. In evaluating the more-likely-than-not recognition threshold, White Mountains must presume that the tax position will be subject to examination by a taxing authority with full knowledge of all relevant information. If the recognition threshold is met, then the tax position is measured at the largest amount of benefit that is more than 50% likely of being realized upon ultimate settlement.
A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

If White Mountains determines in the future that its reserves for unrecognized tax benefits on permanent differences and interest and penalties are not needed, the reversal of $17.7 million of such reserves at December 31, 2012 would be recorded as an income tax benefit and would impact the effective tax rate. If White Mountains determines in the future that its reserves for unrecognized tax benefits on temporary differences are not needed, the reversal of $28.9 million of such reserves at December 31, 2012 would not impact the effective tax rate due to deferred tax accounting but would accelerate the payment of cash to the taxing authority. The vast majority of White Mountains’ reserves for unrecognized tax benefits on temporary differences relate to deductions for loss reserves that the timing of the deductions is uncertain.

F-43


White Mountains classifies all interest and penalties on unrecognized tax benefits as part of income tax expense. During the years ended December 31, 2012, 2011 and 2010 White Mountains recognized $1.2 million, $0.6 million, $1.9 million in interest (benefit) expense, net of any tax benefit. The balance of accrued interest at December 31, 2012 and 2011 is $8.0 million and $6.8 million, net of any tax benefit.

Tax Examinations
With few exceptions, White Mountains is no longer subject to U.S. federal, state or non-U.S. income tax examinations by tax authorities for years before 2005.
The IRS is conducting an examination of income tax returns for 2005 and 2006 for certain U.S. subsidiaries of OneBeacon.  On January 5, 2011, White Mountains received Form 4549-A (Income Tax Discrepancy Adjustments) from the IRS relating to the examination of tax years 2005 and 2006. The estimated total assessment, including interest and utilization of alternative minimum and foreign tax credit carryovers, is $20.8 million. White Mountains disagrees with the adjustments proposed by the IRS and is defending its position. Although the timing of the resolution of these issues is uncertain, it is reasonably possible that the resolution could occur within the next 12 months.  An estimate of the range of potential outcomes cannot be made at this time. When ultimately settled, White Mountains does not expect the resolution of this examination to result in a material change to its financial position.
On July 28, 2011, the IRS commenced an examination of the income tax returns for 2007, 2008 and 2009 for certain U.S. subsidiaries of OneBeacon.  White Mountains has received proposed adjustments but does not expect the resolution of this examination to result in a material change to its financial position.
On December 15, 2011, the IRS commenced an examination of the income tax returns for 2010 for certain U.S. subsidiaries of AFI.  Pursuant to a Stock Purchase Agreement dated as of May 17, 2011 between White Mountains and Allstate, White Mountains is required to indemnify Allstate for any changes in pre-closing taxes.  White Mountains does not expect the resolution of this examination to result in a material change to its financial position.
The IRS conducted an examination of income tax returns for 2006 and 2007 for certain U.S. subsidiaries of Sirius Group.  On October 26, 2011, the Sirius Group received and signed the IRS Revenue Agent’s Report, which contained no proposed adjustments.  The IRS also examined the U.S. income tax return filed by WM Belvaux S.à r.l., a Luxembourg subsidiary, for tax year 2007.  On May 3, 2011, the exam was completed with no proposed adjustments.

Note 8. Derivatives

Variable Annuity Reinsurance

White Mountains has entered into agreements to reinsure death and living benefit guarantees associated with certain variable annuities in Japan.  At December 31, 2012, the total guarantee value was approximately ¥230.0 billion (approximately $2.7 billion at exchange rates on that date).  The collective account values of the underlying variable annuities were approximately 87% of the guarantee value at December 31, 2012.

The fair value of White Mountains’ variable annuity reinsurance liabilities are estimated using actuarial and capital market assumptions related to the projected discounted cash flows over the term of the reinsurance agreement. Assumptions regarding future policyholder behavior, including surrender and lapse rates, are generally unobservable inputs and significantly impact the fair value estimates. Market conditions including, but not limited to, changes in interest rates, equity indices, market volatility and foreign currency exchange rates as well as the variations in actuarial assumptions regarding policyholder behavior may result in significant fluctuations in the fair value estimates. Generally, the liabilities associated with these guarantees increase with declines in the equity markets, interest rates and currencies against the Japanese yen, as well as with increases in market volatilities. White Mountains uses derivative instruments, including put options, interest rate swaps, total return swaps on bond and equity indices and forwards and futures contracts on major equity indices, currency pairs and government bonds, to mitigate the risks associated with changes in the fair value of the reinsured variable annuity guarantees. The types of inputs used to estimate the fair value of these derivative instruments, with the exception of actuarial assumptions regarding policyholder behavior and risk margins, are generally the same as those used to estimate the fair value of variable annuity liabilities.

WM Life Re enters into both over-the-counter (“OTC”) and exchange traded derivative instruments to economically hedge the liability from the variable annuity benefit guarantee. In the case of OTC derivatives, WM Life Re has exposure to credit risk for amounts that are uncollateralized by counterparties. WM Life Re’s internal risk management guidelines establish net counterparty exposure thresholds that take into account over-the-counter counterparties’ credit ratings. WM Life Re has entered into master netting agreements with certain of its OTC counterparties whereby the collateral provided (held) is calculated on a net basis. Collateral held consists of money-market instruments, carried at amortized cost, which approximates fair value.  The OTC derivative contracts are subject to restrictions on liquidation of the instruments and distribution of proceeds under collateral agreements.

Forward Contracts

White Mountains is exposed to foreign currency risk related to Sirius International as its functional currency is the Swedish krona (SEK). In addition, Sirius International holds net assets denominated in euros (EUR), British pound sterling (GBP), and U.S. Dollars (USD). Beginning in September 2012, White Mountains entered into forward contracts through a twelve month trial program with a third-party currency specialist manager to determine whether purchasing external forward currency contracts would improve the management of foreign currency exposure at Sirius Group. White Mountains monitors its exposure to foreign currency and adjusts its forward positions within the risk guidelines and ranges established by senior management for each currency, as necessary. While White Mountains actively manages its forward positions, mismatches between movements in foreign currency rates and its forward contracts may result in currency positions being outside the pre-defined ranges and/or foreign currency losses. At December 31, 2012, White Mountains held approximately $31.2 million (SEK 202.8 million) total gross notional value of foreign currency forward contracts.
All of White Mountains’ forward contracts are traded over-the-counter. The fair value of the contracts has been estimated using OTC quotes for similar instruments and accordingly, the measurements have been classified as Level 2 measurements at December 31, 2012.
The following tables summarize the changes in White Mountains’ forward contracts for the year ended December 31, 2012:

NOTE 9. Earnings Per Share

Basic earnings per share amounts are based on the weighted average number of common shares outstanding including unvested restricted shares that are considered participating securities. Diluted earnings per share amounts are based on the weighted average number of common shares including unvested restricted shares and the net effect of potentially dilutive common shares outstanding. The following table outlines the Company’s computation of earnings per share for the years ended December 31, 2012, 2011 and 2010:

NOTE 10. Retirement and Postretirement Plans

OneBeacon sponsors qualified and non-qualified, non-contributory, defined benefit pension plans covering substantially all employees who were employed as of December 31, 2001, as well as former employees and retirees that had met the eligibility requirements. Current plans include the OneBeacon qualified pension plan (the “Qualified Plan”) and the OneBeacon non-qualified pension plan (the “Non-qualified Plan”) (collectively the “Plans”). The Plans were frozen and curtailed in 2002 and, as a result, the projected benefit obligation is equal to the accumulated benefit obligation.
The benefits for the Plans are based primarily on years of service and employees’ compensation through December 31, 2002. OneBeacon’s funding policy is consistent with the funding requirements of U.S. federal laws and regulations.
The following tables set forth the obligations and funded status, assumptions, plan assets and cash flows associated with the various pension plans at December 31, 2012 and 2011:

The funded status of the consolidated pension plans at December 31, 2012 was $5.2 million, which represents an over-funding of $32.8 million related to the Qualified Plan and an under-funding of $27.6 million related to the Non-qualified Plan. The Non-qualified Plan, which is unfunded, does not hold any assets. OneBeacon has set aside $13.4 million in an irrevocable rabbi trust for the benefit of Non-qualified Plan participants. In accordance with GAAP, the assets held in the rabbi trust are not reflected in the funded status of the consolidated pension plans as presented.

Assumptions
The weighted average discount rate assumptions used to determine benefit obligations was 3.64% and 4.38% at December 31, 2012 and 2011. The weighted average assumptions used to determine net periodic benefit cost included a 4.38% discount rate and 5.75% expected long-term rate of return on plan assets for the year ended December 31, 2012.  The weighted average assumptions used to determine net periodic benefit cost included a 4.94% discount rate and 5.75% expected long-term rate of return on plan assets for the year ended December 31, 2011.
OneBeacon’s discount rate assumptions used to account for the Plans reflect the rates at which the benefit obligations could be effectively settled. For 2012 and 2011, in addition to consideration of published yields for high quality long-term corporate bonds, U.S. Treasuries and insurance company annuity contract pricing, consideration was given to a cash flow matching analysis.
OneBeacon performed an analysis of expected long-term rates of return based on the allocation of its Qualified Plan assets at December 31, 2012 and 2011 to develop expected rates of return for 2012 and 2011 for each significant asset class or economic indicator. A range of returns was developed based both on forecasts and on broad market historical benchmarks for expected return, correlation, and volatility for each asset class.

Plan Assets
The majority of the Qualified Plans’ assets are managed by Prospector Partners, LLC (“Prospector”), a related party (see Note 18). The investment policy places an emphasis on preserving invested assets through a diversified portfolio of high-quality income producing investments and equity investments.
The investment management process integrates the risks and returns available in the investment markets with the risks and returns available to the Qualified Plan in establishing the proper allocation of invested assets. The asset classes include fixed maturity, equity, convertible fixed maturities, and cash and short-term investments. Fixed maturity and convertible fixed maturities include bonds, convertible fixed maturities and convertible preferred stocks of companies from diversified industries. Equity securities primarily include investments in large-cap and mid-cap companies primarily located in the United States. Cash and short-term investments include registered investment companies and common/collective trust funds.
The factors examined in establishing the appropriate investment mix include the outlook for risk and return in the various investment markets and sectors and the long-term need for capital growth.
The Qualified Plan’s investments are stated at fair value. Many factors are considered in arriving at fair market value. In general, fixed maturity investments such as corporate bonds and government securities are valued based on yields currently available on comparable securities of issuers with similar credit ratings. Shares of common and preferred stock are valued at quoted market prices when available.  Convertible fixed maturities are valued based on quoted market prices, analysis of listed markets and use of sensitivity analyses. Registered investment companies are valued at the net asset value as reported by the fund at year-end.
The fair value of the Qualified Plan’s assets and their related inputs at December 31, 2012 by asset category were as follows:

As described above, the Qualified Plan’s investment securities are exposed to various risks such as interest rate, market, and credit risks. Market prices of common equity securities, in general, are subject to fluctuations which would cause the amount to be realized upon sale or exercise of the instruments to differ significantly from the current reported value. The fluctuations may result from perceived changes in the underlying economic characteristics of the investee, the relative price of alternative investments, general market conditions and supply and demand imbalances for a particular security. Increases and decreases in prevailing interest rates generally translate into decreases and increases in fair values of fixed maturity and convertible fixed maturity investments, respectively. Additionally, fair values of interest rate sensitive instruments may be affected by the creditworthiness of the issuer, prepayment options, relative values of alternative investments, the liquidity of the instrument and other general market conditions.
 
Cash Flows

Other Benefit Plans
OneBeacon sponsors an employee savings plan (defined contribution plan) covering the majority of its employees. The contributory plan provides qualifying employees with matching contributions of 50% up to the first six percent of salary (subject to U.S. federal limits on allowable contributions in a given year). Total expense for the plan was $2.8 million, $3.0 million and $3.8 million in 2012, 2011 and 2010.
OneBeacon’s employee stock ownership plan (“ESOP”) provides all of its participants with an annual base contribution in common shares equal to 3% of their salary, up to the applicable Social Security wage base ($110,100 for 2012). Additionally, those participants not otherwise eligible to receive certain other OneBeacon benefits can earn a variable contribution of up to 6% of their salary, subject to the applicable IRS annual covered compensation limits ($250,000 for 2012) and contingent upon OneBeacon’s performance.  In April 2007, the ESOP was merged into the 401(k) Plan to form the OneBeacon 401(k) Savings and ESOP Plan (“KSOP”). White Mountains recorded $4.8 million, $6.3 million and $3.0 million in compensation expense to pay benefits and allocate common shares to participant’s accounts for the years ended 2012, 2011 and 2010.
OneBeacon had a post-employment benefit liability, which primarily relates to disability coverage for former employees, of $7.1 million and $6.7 million at December 31, 2012 and 2011.
Sirius Group sponsors an employee savings plan (defined contribution plan) covering the majority of its U.S. employees. The contributory plan provides qualifying employees with matching contributions of 100% up to the first two percent and 50% of the next four percent of salary (subject to U.S. federal limits on allowable contributions in a given year). Total expense for the plan was $1.0 million, $1.1 million and $1.0 million in 2012, 2011 and 2010.
Sirius Group provides all of its participants with a variable contribution up to 7% of their salary, contingent upon Sirius Group’s performance.
Sirius Group funds other governmental pension plans and other employee savings plans in various countries for its global employees. The expense for those plans totaled $7.5 million, $9.6 million and $8.1 million in 2012, 2011 and 2010.

NOTE 11. Employee Share-Based Incentive Compensation Plans

White Mountains’ share-based incentive compensation plans are designed to incentivize key employees and service providers to maximize shareholder value over long periods of time. White Mountains believes that this is best pursued by utilizing a pay-for-performance program that closely aligns the financial interests of management with those of its shareholders. White Mountains accomplishes this by emphasizing highly variable long-term compensation that is contingent on performance over a number of years rather than entitlements. White Mountains expenses all its share-based compensation. As a result, White Mountains’ calculation of its owners’ returns includes the expense of all outstanding share-based compensation awards.

Incentive Compensation Plans
White Mountains’ Long-Term Incentive Plan (the “WTM Incentive Plan”) provides for grants of various types of share-based and non share-based incentive awards to key employees and service providers of White Mountains. The WTM Incentive Plan was adopted by the Board, was approved by the Company’s sole shareholder in 1985 and was subsequently amended by its shareholders in 1995, 2001, 2003, 2005 and 2010. Share-based incentive awards that may be granted under the plan include performance shares, restricted shares, performance units, incentive stock options and non-qualified stock options (“Non-Qualified Options”). Performance shares are conditional grants of a specified maximum number of common shares or an equivalent amount of cash. Awards generally vest at the end of a three-year period, are subject to the attainment of pre-specified performance goals, and are valued based on the market value of common shares at the time awards are paid. Performance shares earned under the WTM Incentive Plan are typically paid in cash but may be paid in common shares or by deferral into certain non-qualified compensation plans of White Mountains. Compensation expense is recognized on a pro rata basis over the vesting period of the awards.
The OneBeacon Long-Term Incentive Plan (the “OneBeacon Incentive Plan”) provides for grants to key employees of OneBeacon Ltd various types of share-based incentive awards, including performance shares, restricted shares, restricted stock units and Non-Qualified Options.
The Sirius Group Performance Plan provides for granting phantom White Mountains performance shares (the “WTM Phantom Share Plan”) to certain key employees of Sirius Group. Beginning with the 2011-2013 performance cycle, employees of Sirius Group were granted performance shares from the WTM Incentive Plan.  The performance goals for full payment of performance shares issued under these plans are identical to those of the WTM Incentive Plan. Performance shares earned under the WTM Phantom Share Plan are typically paid in cash but could be paid in common shares or by deferral into certain non-qualified compensation plans of White Mountains.  Compensation expense is recognized on a pro rata basis over the vesting period of the awards.
White Mountains offers certain types of share-based compensation under qualified retirement plans. The defined contribution plans of OneBeacon and Sirius Group (the “401(k) Plans”) offer its participants the ability to invest their balances in several different investment options, including the Company’s or OneBeacon’s common shares. OneBeacon’s employee stock ownership plan (“ESOP”) is a OneBeacon-funded benefit plan that provides all of its participants with an annual base contribution in common shares equal to 3% of their salary, up to the applicable Social Security wage base ($110,100 for 2012). Additionally, those participants not otherwise eligible to receive certain other OneBeacon benefits can earn a variable contribution of up to 6% of their salary, subject to the applicable IRS annual covered compensation limits ($250,000 for 2012) and contingent upon OneBeacon’s performance.  In April 2007, the ESOP was merged into the 401(k) Plan to form the OneBeacon 401(k) Savings and ESOP Plan (“KSOP”).  Sirius Group’s profit sharing plan is a Sirius Group-funded benefit plan that provides all of its participants with a variable contribution up to 7% of their salary, contingent upon Sirius Group’s performance.

Performance Shares
Performance shares are designed to reward company-wide performance. The level of payout ranges from zero to two times the number of shares initially granted, depending on White Mountains’ financial performance. Performance shares become payable at the conclusion of a performance cycle (typically three years) if pre-defined financial targets are met.
The principal performance measure used for determining performance share payouts is after-tax growth in White Mountains’ intrinsic business value per share. The Compensation Committee historically has considered the growth in intrinsic business value per share to be based equally on the growth of economic value per share and growth in adjusted book value per share, both inclusive of dividends. Economic value is calculated by adjusting the GAAP book value per share for differences between the GAAP carrying values of certain assets and liabilities and White Mountains’ estimate of their underlying economic values (for example, the time value discount in loss reserves).

WTM performance share payments in 2012 for the 2009-2011 performance cycle ranged from 147% to 155% of target. At December 31, 2012, White Mountains paid $9.9 as a partial payment for the 2010-2012 performance cycle. There were no payments made in 2011 and 2010 for the 2008-2010 and 2007-2009 performance cycles; those performance shares did not meet the threshold performance goals and expired.
(2) 
Amounts include changes in assumed forfeitures, as required under GAAP.

For the 2009-2011 performance cycle, the Company issued common shares for 9,577 performance shares earned and all other performance shares earned were settled in cash.
If all outstanding performance shares had vested on December 31, 2012, the total additional compensation cost to be recognized would have been $21.1 million, based on accrual factors at December 31, 2012 (common share price and payout assumptions).

The targeted performance goal for full payment of outstanding performance shares granted under the WTM Incentive Plan to non-investment personnel for the 2012-2014 performance cycles is an 8% growth in intrinsic business value per share. Growth of 2% or less would result in no payout and growth of 14% or more would result in a payout of 200%.
The targeted performance goal for full payment of outstanding performance shares granted under the WTM Incentive Plan to non-investment personnel for the 2011-2013 performance cycles is a 10% growth in intrinsic business value per share. Growth of 3% or less would result in no payout and growth of 17% or more would result in a payout of 200%.
The targeted performance goal for full payment of outstanding performance shares granted under the WTM Incentive Plan to non-investment personnel for the 2010-2012 performance cycles is an 11% growth in intrinsic business value per share. Growth of 4% or less would result in no payout and growth of 18% or more would result in a payout of 200%.
For investment personnel, the targeted performance goal for full payment of outstanding performance shares granted under the WTM Incentive Plan is based one-third on growth in intrinsic business value per share (as described above), one-third on achieving a total return on invested assets as measured against metrics based on U.S. Treasury Note returns and one-third on achieving a total return on invested assets as measured against metrics based on the Barclays U.S. Intermediate Aggregate Index returns.

For Prospector Partners, the targeted performance goal for full payment of outstanding performance shares granted under the WTM Incentive Plan is based equally on growth in intrinsic business value per share (as described above) and achieving a total return on invested assets as measured against metrics based on U.S. Treasury Note returns.

During the first quarter of 2007, White Mountains issued 15,000 restricted shares to the Company’s Chairman and CEO in connection with his hiring that would vest in the event of a change in control of the Company before January 20, 2012.  During 2010, the Compensation Committee modified the vesting terms so that the 15,000 restricted shares time vest in three equal annual installments beginning on January 20, 2013. During 2012, the Compensation Committee accelerated the vesting date of the first installment from January 20, 2013 to December 31, 2012.
 
During the third quarter of 2012, White Mountains issued 2,500 restricted shares that vest on January 1, 2015 and 1,200 restricted shares that vest on July 16, 2015. During the first quarter of 2012, White Mountains issued 25,460 restricted shares that vest on January 1, 2015 and 3,000 restricted shares that vest in two equal annual installments beginning in February 2014.  During the second quarter of 2011, White Mountains issued 250 restricted shares that vest on January 1, 2014. During the first quarter of 2011, White Mountains issued 27,000 restricted shares that vest on January 1, 2014.  During the first quarter of 2010, White Mountains issued 19,750 restricted shares that vested on December 31, 2012. The unrecognized compensation cost associated with outstanding restricted share awards at December 31, 2012 is expected to be recognized ratably over the remaining vesting periods.

Stock Options

Non-Qualified Options
In January 2007, the Company issued 200,000 seven-year Non-Qualified Options to the Company’s Chairman and CEO (the “original grant”) that vest in equal annual installments over five years and that had an initial exercise price of $650 per common share that escalated at an annual rate of 5% less the annual regular dividend rate (the “Escalator”). The fair value of the Non-Qualified Options was $27.2 million at the grant date.  The fair value of the Non-Qualified Options at the grant date was estimated using a closed-form option model using an expected volatility assumption of 29.7%, a risk-free interest rate assumption of 1.1% (or 4.7% less the Escalator), a forfeiture assumption of 0%, an expected dividend rate assumption of 1.4% and a term assumption of seven years.
At the 2010 Annual General Meeting of Members held on May 26, 2010 (the “modification date”), the Company’s shareholders approved the following amendments to the Non-Qualified Options (the “amended grant”): (1) extend the term of the Non-Qualified Options by three years to January 20, 2017; (2) freeze the exercise price at $742 per common share, the exercise price on February 24, 2010; (3) extinguish 75,000 of the 200,000 Non-Qualified Options; and (4) limit the potential in-the-money value of the Non-Qualified Options in excess of $100 million to 50% of the amount in excess of $100 million.  The fair value of the amended grant was $4.4 million at the modification date, while the fair value of the original grant as of the modification date was $3.5 million. The fair value of the amended grant was estimated using a closed-form option model using an expected volatility assumption of 34.0%, a risk-free interest rate assumption of 2.43%, a forfeiture assumption of 0%, an expected dividend rate assumption of 0.32% and a term assumption of 6.67 years. The fair value of the original grant as of the modification date was estimated using a closed-form option model using an expected volatility assumption of 41.0%, a risk-free interest rate assumption of 1.57%, a forfeiture assumption of 0%, an expected dividend rate assumption of 0.32% and a term assumption of 3.67 years.
Prior to the modification, $18.2 million of the original grant fair value had been amortized into income. In connection with the modification, White Mountains recognized $8.7 million of the remaining $9.0 million of unamortized option expense related to the original grant.  As of the first quarter in 2011, the Non-Qualified Options have been fully amortized.
For the years ended December 31, 2011 and 2010 White Mountains recognized a total of $0.1 million and $11.9 million of expense related to amortizing the Non-Qualified Options.

If the outstanding OneBeacon performance shares had been vested on December 31, 2012, the total additional compensation cost to be recognized would have been $1.9 million, based on December 31, 2012 accrual factors (common share price and payout assumptions).
The targeted performance goal for full payment of the outstanding OneBeacon performance shares granted during 2012 is growth in intrinsic business value per share of 10%. At a growth in intrinsic business value per share of 3% or less, no performance shares would be earned and at a growth in intrinsic business value per share of 17% or more, 200% of performance shares would be earned. 
The targeted performance goal for full payment of the outstanding OneBeacon performance shares granted during 2011 is growth in intrinsic business value per share of 11%. At a growth in intrinsic business value per share of 4% or less, no performance shares would be earned and at a growth in intrinsic business value per share of 18% or more, 200% of performance shares would be earned. 
The targeted performance goal for full payment of the outstanding OneBeacon performance shares granted during 2010 is growth in intrinsic business value per share of 12%. At a growth in intrinsic business value per share of 5% or less, no performance shares would be earned and at a growth in intrinsic business value per share of 19% or more, 200% of performance shares would be earned.

Non-Qualified Options
In November 2006, in connection with its initial public offering, OneBeacon Ltd. issued to its key employees 1,420,000 fixed price OneBeacon Non-Qualified Options to acquire OneBeacon Ltd. common shares at an above-market fixed exercise price.  The options vest in equal installments on each of the third, fourth and fifth anniversaries of their issuance and expire 5.5 years from the date of issuance.  The fair value of each option award at grant was estimated using a Black-Scholes option pricing model using an expected volatility assumption of 30%, a risk-free interest rate assumption of 4.6%, a forfeiture assumption of 5%, an expected dividend rate assumption of 3.4% and an expected term assumption of 5.5 years.  The options originally had a per share exercise price of $30.00.  On May 27, 2008, the OneBeacon Compensation Committee of the Board of Directors (the “OB Compensation Committee”) amended the exercise price to $27.97 as a result of the $2.03 per share special dividend paid in the first quarter of 2008. On November 16, 2010, the OB Compensation Committee adjusted the exercise price to $25.47 as a result of the $2.50 per share special dividend paid in the third quarter of 2010.
The compensation expense associated with the options and the incremental fair value of the award modifications is being recognized ratably over the remaining period.

On March 1, 2012, OneBeacon issued 300,000 restricted shares to key employees that vest in two equal installments on February 28, 2014 and 2015. On May 25, 2011, OneBeacon issued 630,000 restricted shares to its CEO that vest four equal annual installments beginning on February 22, 2014, 2015, 2016 and 2017.  Concurrently with the grant of the restricted shares, 35,000 OneBeacon performance shares issued to OneBeacon’s CEO for the 2011-2013 performance share cycle were forfeited and performance share awards to OneBeacon’s CEO for the subsequent 5 years have been or will also be reduced by 35,000 shares.  The restricted shares contain dividend participation features, and therefore, are considered participating securities.  The unrecognized compensation cost associated with outstanding restricted share awards at December 31, 2012 is expected to be recognized ratably over the remaining vesting periods.

Restricted Stock Units
The Non-Qualified Options granted by OneBeacon Ltd., in connection with its initial public offering, did not include a mechanism in the options to reflect the contribution to total return from the regular quarterly dividend.  As a result, during the first quarter of 2008, OneBeacon granted 116,270 Restricted Stock Units (“RSUs”) to actively employed option holders.  The RSUs were scheduled to vest in three equal installments on each of November 9, 2009, 2010 and 2011 subject to, for each vesting tranche of units, the attainment of 4% growth in OneBeacon’s book value per share from January 1, 2008 through the end of the calendar year immediately following the applicable vesting date.
Consistent with the terms of the RSU plan, all of the tranches of RSUs vested and were deferred into a OneBeacon non-qualified deferred compensation plan that was paid out in May 2012.
The expense associated with the RSUs was recognized ratably over the vesting period.  For the years ended December 31, 2011 and 2010, OneBeacon recognized expense of $0.1 million and $0.5 million.

Share-based Compensation Under Qualified Retirement Plans

Contributions to the KSOP with respect to the years ended 2012, 2011 and 2010 were made with either the Company’s or OneBeacon Ltd.’s common shares, dependent on the employer.  The variable contribution amounts for eligible participants of the KSOP constituted approximately 3%, 2% and 1% of salary for the years ended 2012, 2011 and 2010. White Mountains recorded $4.8 million, $6.3 million and $3.0 million in compensation expense to pay benefits and allocate common shares to participant’s accounts for the years ended 2012, 2011 and 2010. As of December 31, 2012 and 2011, the plans owned 3% or less of either of the Company’s or OneBeacon Ltd.’s total common shares outstanding.  All White Mountains common shares held by the KSOP are considered outstanding for earnings (loss) per share computations.

NOTE 13. Statutory Capital and Surplus

White Mountains’ insurance and reinsurance operations are subject to regulation and supervision in each of the jurisdictions where they are domiciled and licensed to conduct business. Generally, regulatory authorities have broad supervisory and administrative powers over such matters as licenses, standards of solvency, premium rates, policy forms, investments, security deposits, methods of accounting, form and content of financial statements, reserves for unpaid loss and LAE, reinsurance, minimum capital and surplus requirements, dividends and other distributions to shareholders, periodic examinations and annual and other report filings. In general, such regulation is for the protection of policyholders rather than shareholders.  In addition, the NAIC uses risk-based capital (“RBC”) standards for property and casualty insurers as a means of monitoring certain aspects affecting the overall financial condition of insurance companies. At December 31, 2012, White Mountains’ active insurance and reinsurance operating subsidiaries exceeded their respective RBC requirements.
OneBeacon’s consolidated combined policyholders’ surplus of its insurance operating subsidiaries as reported to regulatory authorities as of December 31, 2012 and 2011 was $0.9 billion and $1.0 billion. OneBeacon’s consolidated combined statutory net income for the years ended December 31, 2012, 2011 and 2010 was $82.0 million, $119.6 million and $257.2 million. The principal differences between OneBeacon’s combined statutory amounts and the amounts reported in accordance with GAAP include deferred acquisition costs, deferred taxes, and market value adjustments for debt securities. The minimum policyholders' surplus necessary to satisfy OneBeacon's regulatory requirements was $207.5 million at December 31, 2012, which equals the authorized control level of the NAIC risk-based capital of OneBeacon’s primary top tier regulated operating subsidiary.
Sirius International is subject to regulation and supervision in Sweden by the Financial Supervisory Authority (“FSA”). Sirius International’s total regulatory capital at December 31, 2012 was $2.5 billion.  In accordance with FSA regulations, Sirius International holds restricted equity of $1.6 billion as a component of Swedish regulatory capital. This restricted equity cannot be paid as dividends. The minimum regulatory capital held by Sirius International necessary to satisfy the requirements established by the FSA was $109.2 million at December 31, 2012.
Sirius America’s policyholders’ surplus, as reported to regulatory authorities as of December 31, 2012 and 2011, was $528.3 million and $533.7 million. Sirius America’s statutory net income for the years ended December 31, 2012, 2011 and 2010 was $26.2 million, $101.4 million and $70.2 million The principal differences between Sirius America’s statutory amounts and the amounts reported in accordance with GAAP include deferred acquisition costs, deferred taxes, gains recognized under retroactive reinsurance contracts and market value adjustments for debt securities. The minimum policyholders’ surplus necessary to satisfy Sirius America’s regulatory requirements was $127.8 million at December 31, 2012, which equals the authorized control level of the NAIC risk-based capital based on Sirius America’s policyholders’ surplus.
Central National’s policyholders’ surplus, as reported to regulatory authorities as of December 31, 2012 and 2011, was $11.2 million and $13.4 million. Central National’s statutory net income for the years ended December 31, 2012 and 2011 was $1.7 million and $0.1 million. The minimum policyholders’ surplus necessary to satisfy Central National’s regulatory requirements was $1.7 million at December 31, 2012, which equals the authorized control level of the NAIC risk-based capital based on Central National’s policyholders’ surplus.
American General's policyholders' surplus, as reported to regulatory authorities as of December 31, 2012 was $8.6 million. The minimum policyholders' surplus necessary to satisfy American General’s regulatory requirements was $0.1 million at December 31, 2012, which equals the authorized control level of the NAIC risk-based capital based on American General’s policyholders' surplus.
American General Property's policyholders' surplus, as reported to regulatory authorities as of December 31, 2012 was $24.5 million. The minimum policyholders' surplus necessary to satisfy American General Property's regulatory requirements was $2.5 million at December 31, 2012, which equals the authorized control level of the NAIC risk-based capital based on American General Property’s policyholders' surplus.
PICO's policyholders' surplus, as reported to regulatory authorities as of December 31, 2012 was $6.3 million. The minimum policyholders' surplus necessary to satisfy PICO's regulatory requirements was $0.2 million at December 31, 2012, which equals the authorized control level of the NAIC risk-based capital based on PICO's policyholders' surplus.
Citation's policyholders' surplus, as reported to regulatory authorities as of December 31, 2012 was $13.1 million. The minimum policyholders' surplus necessary to satisfy Citation's regulatory requirements was $0.9 million at December 31, 2012, which equals the authorized control level of the NAIC risk-based capital based on Citation's policyholders' surplus.
White Shoals Re Ltd. (“White Shoals Re”) is also subject to regulation and supervision by the Bermuda Monetary Authority (“BMA”). Generally, the BMA has broad supervisory and administrative powers over such matters as licenses, standards of solvency, investments, methods of accounting, form and content of financial statements, minimum capital and surplus requirements, and annual and other report filings. In general, such regulation is for the protection of policyholders rather than shareholders. As of December 31, 2012, White Shoals Re had statutory capital and surplus of $15.5 million. The minimum regulatory capital held by White Shoals Re necessary to satisfy the requirements established by the BMA was $7.0 million at December 31, 2012.

F-61

HG Re is a Special Purpose Insurer under Bermuda insurance regulations and is subject to regulation and supervision by the BMA. As of December 31, 2012, HG Re had statutory capital of $412.0 million. As a Special Purpose Insurer, HG Re does not have minimum regulatory capital requirements.
BAM is domiciled in New York and is subject to regulation by the New York Department of Financial Services. New York financial guarantee insurance law establishes single risk and aggregate limits with respect to insured obligations insured by financial guarantee insurers. BAM’s members’ surplus, as reported to regulatory authorities as of December 31, 2012 was $483.7 million, which exceeds the minimum members’ surplus necessary for BAM to maintain its New York State financial guarantee insurance license of $65.0 million.

Dividend Capacity
There are no restrictions under Bermuda law or the law of any other jurisdiction on the payment of dividends from retained earnings by White Mountains. However, under the insurance laws of the states and jurisdictions under which White Mountains' insurance and reinsurance operating subsidiaries are domiciled, an insurer is restricted with respect to the timing and the amount of dividends it may pay without prior approval by regulatory authorities. At December 31, 2012, White Mountains’ top tier insurance and reinsurance subsidiaries have approximately $2.9 billion of GAAP shareholders' equity (net of $268 million of noncontrolling interest at OneBeacon), $1.2 billion of which can be distributed to White Mountains without prior regulatory approval. As a result, at December 31, 2012, $1.7 billion of White Mountains' GAAP shareholders' equity held in its insurance and reinsurance subsidiaries was not available for the payment of dividends without prior regulatory approval, and approximately $800 million of White Mountains’ retained earnings is unrestricted with respect to the payment of dividends to White Mountains’ common shareholders. When determining whether to make distributions from its insurance and reinsurance operating subsidiaries, White Mountains also considers factors such as internal capital targets and rating agency capital requirements. Accordingly, there can be no assurance regarding the amount of such dividends that may be paid by such subsidiaries in the future.
Following is a description of the dividend capacity of White Mountains’ insurance and reinsurance operating subsidiaries:

OneBeacon:
Generally, OneBeacon's top tier regulated insurance operating subsidiaries have the ability to pay dividends during any twelve-month period without the prior approval of regulatory authorities in an amount set by formula based on the greater of prior year statutory net income or 10% of prior year end statutory surplus, subject to the availability of unassigned funds. OneBeacon Insurance Company (“OBIC”), OneBeacon's primary top tier regulated insurance operating subsidiary, has the ability to pay $329.9 million of dividends during 2013 (based on its 2012 statutory net income of $329.9 million) without prior approval of regulatory authorities, subject to the availability of unassigned funds. The amount of dividends available to be paid by OBIC in any given year is also subject to cash flow and earnings generated by OBIC's business, which now just comprises the Runoff Business, as well as to dividends received from its subsidiaries, including Atlantic Specialty Insurance Company (“ASIC”). At December 31, 2012, OBIC had $0.7 billion of unassigned funds and $0.9 billion of statutory surplus. 
As disclosed in Note 2 - “Significant Transactions”, during the fourth quarter of 2012, OneBeacon executed various intercompany reinsurance agreements which, along with other internal capital transactions among our insurance operating subsidiaries, resulted in ASIC becoming the lead insurance company for the ongoing specialty business and OBIC becoming the lead insurance company for the Runoff Business. As a result of the internal restructuring transactions, OBIC’s 2012 statutory net income was significantly higher than that of the OneBeacon’s consolidated combined statutory net income as statutory net losses at lower-tiered subsidiaries more than offset the income recorded at OBIC. Notwithstanding these restructuring transactions, OneBeacon continues to manage its statutory capital on a combined basis. Although OBIC remains a top tier regulated insurance operating subsidiary and maintains sufficient statutory capital to support the Runoff Business, the majority of the group's statutory capital is now included in ASIC to support the ongoing specialty business.
ASIC has the ability to pay dividends during any twelve-month period without the prior approval of regulatory authorities in an amount set by formula based on the lesser of net investment income, as defined by statute, or 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus. Given the changes in structure noted above, ASIC will likely require prior approval by regulatory authorities in order to pay dividends until it builds up a historical net investment income and earned surplus balance under its new structure. At December 31, 2012, ASIC had negative earned surplus and $0.7 billion of statutory surplus.
During 2012, OneBeacon's top tier regulated insurance operating subsidiaries paid $173.1 million of dividends to their immediate parent, which included the distribution of a regulated insurance subsidiary with a value of $34.0 million.
During 2012, OneBeacon's unregulated insurance operating subsidiaries paid $4.9 million of dividends to their immediate parent.  At December 31, 2012, OneBeacon's unregulated insurance operating subsidiaries had $28.6 million of net unrestricted cash, short-term investments and fixed maturity investments.

F-62


During 2012, OneBeacon Ltd. paid $80.0 million of regular quarterly dividends to its common shareholders. White Mountains received $60.0 million of these dividends.
At December 31, 2012, OneBeacon Ltd. and its intermediate holding companies had $272.4 million of net unrestricted cash, short-term investments and fixed maturity investments and $33.3 million of common equity securities and convertible fixed maturity investments outside of its regulated and unregulated insurance operating subsidiaries.

Sirius Group:
Subject to certain limitations under Swedish law, Sirius International is permitted to transfer a portion of its pre-tax income to its Swedish parent companies to minimize taxes (referred to as a group contribution). In 2012, Sirius International transferred $82.0 million of its 2011 pre-tax income to its Swedish parent companies as a group contribution. In 2013, Sirius International currently intends to transfer approximately $110.0 million (based on the December 31, 2012 SEK to USD exchange rate) of its 2012 pre-tax income to its Swedish parent companies as a group contribution.
Sirius International has the ability to pay dividends subject to the availability of unrestricted statutory surplus. Historically, Sirius International has allocated the majority of its pre-tax income, after group contributions to its Swedish parent companies, to the Safety Reserve (see “Safety Reserve” below). At December 31, 2012, Sirius International had $852.0 million (based on the December 31, 2012 SEK to USD exchange rate) of unrestricted statutory surplus, which is available for distribution in 2013. The amount of dividends available to be paid by Sirius International in any given year is also subject to cash flow and earnings generated by Sirius International’s business, as well as to dividends received from its subsidiaries, including Sirius America. During 2012, Sirius International distributed $24.0 million of dividends to its immediate parent and declared an additional $75.0 million of dividends at December 31, 2012 (for a total of $99.0 million). The $75.0 million was paid in January 2013. In connection with the Reorganization, Sirius International’s unrestricted statutory surplus increased by $436.3 million due to the contribution of the remaining shares of Sirius America. In 2013, Sirius International currently intends to distribute $50.0 million of dividends to its immediate parent.
Sirius America has the ability to pay dividends during any twelve-month period without the prior approval of regulatory authorities in an amount set by formula based on the lesser of net investment income, as defined by statute, or 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus. Based upon 2012 statutory net investment income, Sirius America has the ability to pay $15.0 million of dividends during 2013 without prior approval of regulatory authorities, subject to the availability of earned surplus.  At December 31, 2012, Sirius America had $528.3 million of statutory surplus and $56.1 million of earned surplus.  In 2012, Sirius America paid $55.0 million of dividends to its immediate parent.
During 2012, Sirius Group distributed $40.0 million to its immediate parent and declared an additional $75.0 million at December 31, 2012 (for a total of $115.0 million). The $75.0 million was paid in January 2013.
At December 31, 2012, Sirius Group and its intermediate holding companies had $72.0 million of net unrestricted cash, short-term investments and fixed maturity investments and $18.0 million of other long-term investments outside of its regulated and unregulated insurance and reinsurance operating subsidiaries.

Capital Maintenance
In connection with Sirius Group's reorganization in October 2011, Sirius International and Sirius America entered into a capital maintenance agreement, which obligates Sirius International to make contributions to Sirius America's surplus in order for Sirius America to maintain surplus equal to at least 125% of the company action level risk based capital as defined in the NAIC Property/Casualty Risk-Based Capital Report. The agreement provides for a maximum contribution to Sirius America of $200.0 million.  Sirius International also provides Sirius America with accident year stop loss reinsurance, which protects Sirius America's accident year loss and allocated loss adjustment expense ratio in excess of 70%, with a limit of $110.0 million.

Safety Reserve
Subject to certain limitations under Swedish law, Sirius International is permitted to transfer pre-tax amounts into an untaxed reserve referred to as a safety reserve. At December 31, 2012, Sirius International’s safety reserve amounted to SEK 9.6 billion or $1.5 billion at the December 31, 2012 exchange rate of 6.50 USD to SEK. Under GAAP, an amount equal to the safety reserve, net of a related deferred tax liability established at the Swedish tax rate, is classified as shareholder's equity. The tax rate in effect on December 31, 2011 was 26.3%. The tax rate utilized on December 31, 2012 was the new Swedish tax rate of 22.0%. Generally, this deferred tax liability is only required to be paid by Sirius International if it fails to maintain predetermined levels of premium writings and loss reserves in future years. As a result of the indefinite deferral of these taxes, Swedish regulatory authorities do not apply any taxes to the safety reserve when calculating solvency capital under Swedish insurance regulations. Accordingly, under local statutory requirements, an amount equal to the deferred tax liability on Sirius International’s safety reserve ($326.7 million at December 31, 2012) is included in solvency capital. Access to the safety reserve is restricted to coverage of reinsurance losses. Access for any other purpose requires the approval of Swedish regulatory authorities. Similar to the approach taken by Swedish regulatory authorities, most major rating agencies generally include the $1.5 billion balance of the safety reserve, without any provision for deferred taxes, in Sirius International’s capital when assessing Sirius International’s financial strength.

F-63


HG Global/BAM:
HG Global has $613.0 million face value of preferred shares outstanding, of which White Mountains owns 97.3%. Holders of the HG Global preferred shares receive cumulative dividends at a fixed annual rate of 6.0% on a quarterly basis, when and if declared by HG Global. HG Global did not declare or pay any preferred dividends in 2012. As of December 31, 2012, HG Global has accrued $16.8 million of dividends payable to holders of its preferred shares, $16.3 million of which is payable to White Mountains and eliminated in consolidation.
HG Re is a Special Purpose Insurer subject to regulation and supervision by the BMA, but does not require regulatory approval to pay dividends. However, HG Re’s dividend capacity is limited by amounts held in the collateral trusts pursuant to the FLRT with BAM. As of December 31, 2012, HG Re had statutory capital of $412.0 million, of which $12.0 million (which primarily relates to accrued interest on the BAM Surplus Notes held by HG Re) was available for dividends to HG Global and $400.0 million was held as collateral in the Supplemental Trust pursuant to the FLRT with BAM.
Interest on the BAM Surplus Notes is payable quarterly at a fixed annual rate of 8.0%. Interest and principal payments on the BAM Surplus Notes are subject to approval of the New York State Department of Financial Services. BAM did not pay any interest on the BAM Surplus Notes in 2012. As of December 31, 2012, HG Global has accrued $18.4 million of interest receivable on the BAM Surplus Notes.

Other Operations:
During 2012, WM Advisors did not pay any dividends to its immediate parent. At December 31, 2012, WM Advisors had approximately $18.4 million of net unrestricted cash and short-term investments.

During 2012, White Mountains paid a $6.6 million common share dividend.

NOTE 14. Segment Information

Symetra
At December 31, 2012, White Mountains owned 17.4 million common shares of Symetra and warrants to acquire an additional 9.5 million common shares. In January 2010, Symetra completed an initial public offering at a price of $12.00 per share, with 25.3 million shares sold by Symetra and 9.7 million shares sold by existing shareholders. White Mountains did not sell any of its shares in the offering. As a result of the offering, White Mountains’ fully converted ownership in Symetra decreased from 24% to approximately 20% during the first quarter of 2010. The issuance of the new Symetra shares at a price below its adjusted book value per share diluted White Mountains’ investment in Symetra’s common shares, resulting in a $16.0 million decrease to White Mountains’ carrying value in Symetra.
White Mountains accounts for its investment in common shares of Symetra using the equity method. Under the equity method, the GAAP carrying value of White Mountains’ investment in Symetra common shares is normally equal to the percentage of Symetra’s GAAP book value represented by White Mountains’ common share ownership, which was 15% at December 31, 2012. At December 31, 2011, due to the prolonged low interest rate environment in which life insurance companies currently operate, White Mountains concluded that its investment in Symetra common shares was other-than-temporarily impaired and wrote down the GAAP book value of the investment to its estimated fair value of $261.0 million, or $15 per share at December 31, 2011.  White Mountains recorded $45.9 million of after-tax equity in losses of unconsolidated affiliates and $136.6 million of after-tax equity in net unrealized losses of unconsolidated affiliates. 
Under GAAP, a decline in the fair value of an investment is considered to be other-than-temporary when the fair value of the investment is not expected to recover to its GAAP carrying value in the near term.  Declines in the fair value of an investment that are considered to be other-than-temporary are recognized as a write-down to the GAAP carrying value of the investment.  The GAAP fair value of an investment is the price that would be paid by a market participant to acquire it in the investment’s principal (or most advantageous) market. For investments that are publicly traded, quoted market prices generally provide the best measurement of GAAP fair value. However, a decline in the quoted market price of an investment below its GAAP carrying value is not necessarily indicative of a loss in value that is other-than-temporary, and in circumstances where the characteristics of the investment being measured are not the same as those for which quoted market prices are available, unadjusted quoted market prices do not represent GAAP fair value. White Mountains’ investment in Symetra common shares is different than the shares that are traded on the public stock exchange, principally due to the size of its position and its representation on Symetra’s Board of Directors. In circumstances like this, GAAP requires that fair value be determined giving consideration to multiple valuation techniques. Management considered three different valuation techniques to determine the GAAP fair value of White Mountains’ investment in Symetra common shares at December 31, 2011.

Valuation techniques based on actuarial appraisal
When determining the value of life insurance holding companies that are acquisition targets, market participants commonly utilize an approach that values the company as the sum of (A) adjusted statutory net worth of any regulated life insurance companies (i.e. statutory surplus plus asset valuation reserve) plus the GAAP net assets of any non-life businesses, less holding company debt and (B) the present value of future earnings related to business in force as of the valuation date plus the present value of future earnings related to business written after the valuation date. Part A of the calculation can be performed using observable inputs from the statutory and GAAP financial statements. Part B of the calculation requires a large number of actuarial calculations including assumptions such as discount rates, mortality, persistency and future investment results that, while based on historical data and are supportable, are nonetheless judgmental and largely unobservable. For Symetra, part A is approximately $15 per share as of December 31, 2011. Symetra management provided White Mountains with an actuarial appraisal that demonstrates that part B would be a meaningful positive value in most reasonable scenarios. When determining the GAAP fair value of White Mountains’ investment in Symetra common shares at December 31, 2011, management ascribed the greatest weight to part A, as it is observable and less subjective.

Valuation techniques based on multiples from recent transactions
White Mountains uses growth in adjusted book value to assess Symetra’s financial performance. Adjusted book value excludes unrealized gains and losses from Symetra’s fixed maturity investment portfolio. Life insurance industry analysts and market participants commonly use multiples of adjusted book value per share to determine relative values of companies in the life insurance industry. Applying this approach to Symetra at December 31, 2011, utilizing multiples which were observed in a recently announced transaction within the life insurance industry provides an estimated fair value range from $16 to $30 per share. However, the range of fair value estimates generated by applying the adjusted book value per share multiple and market premium observed in the recently announced transaction is wide, and there have been no other significant acquisitions of life insurance companies in 2011. Therefore, management did not ascribe significant weight to valuations determined using the adjusted book value per share multiple or market price premium observed in recent acquisition activity when determining the GAAP fair value of White Mountains’ investment in Symetra common shares at December 31, 2011.


F-67


Valuation techniques based on quoted market prices
White Mountains’ representation on Symetra’s Board of Directors gives it the ability to exercise significant influence over Symetra’s operations and policies. Generally, market participants are willing to pay a premium to obtain the ability to exert influence over the operations and policies of an investee, which is not reflected in the quoted market price of Symetra’s common shares. There is no reliable means to calculate the value of this premium for an investment in a life insurance company. The actuarial appraisals used by market participants described above implicitly consider the ability to influence an investee’s operations and policies in the actuarial assumptions underlying projected future earnings, but the value associated with the ability to exert influence is not explicitly calculated separately from other components of value. As a result, management did not ascribe significant weight to valuations based on quoted market prices when determining the GAAP fair value of White Mountains’ investment in Symetra common shares at December 31, 2011, as the premium associated with the ability to exert influence over the operations and policies of Symetra is unobservable and highly subjective.
After considering these valuation techniques, management determined that the best estimate of the GAAP fair value of White Mountains’ investment in Symetra’s common shares at December 31, 2011 was $15 per share. Given the scarcity of relevant observable inputs and the wide range of estimates developed under the approaches used, the estimated GAAP fair value of White Mountains’ investment in Symetra’s common shares involved a significant degree of judgment, is very subjective in nature and, accordingly, is considered a Level 3 fair value measurement.
As a result of recording the write-down, White Mountains’ carrying value of its investment in Symetra differs from the carrying value by applying its ownership share against Symetra’s GAAP equity as normally done under the equity method. The pre-tax basis difference of $195.8 million as of December 31, 2011 is being amortized over a 30 year period pro rata based on estimated future cash flows associated with Symetra’s underlying assets and liabilities to which the basis difference has been attributed. White Mountains continues to record its equity in Symetra’s earnings and net unrealized gains (losses). In addition, White Mountains recognizes the amortization of the basis difference through equity in earnings of unconsolidated affiliates and equity in net unrealized gains (losses) from investments in unconsolidated affiliates consistent with the original attribution of the writedown between equity in earnings and equity in net unrealized gains (losses). For the year ended December 31, 2012, White Mountains recognized after-tax amortization of $3.3 million through equity in earnings of unconsolidated affiliates and $12.1 million through equity in net unrealized gains from investments in unconsolidated affiliates. At December 31, 2012, the pre-tax unamortized basis difference was $179.2 million. Management does not believe that the investment in Symetra’s common shares is other-than-temporarily impaired at December 31, 2012.
White Mountains accounts for its Symetra warrants as derivatives with changes in fair value recognized through the income statement as a gain or loss recognized through other revenues.  White Mountains uses a Black Scholes valuation model to determine the fair value of the Symetra warrants.  The major assumptions used in valuing the Symetra warrants at December 31, 2012 were a risk free rate of 0.21%, volatility of 38.9%, an expected life of 1.6 years, a strike price of $11.49 per share and a share price of $12.98 per share.
During 2012, White Mountains received cash dividends from Symetra of $4.9 million on its common share investment which is accounted for as a reduction of White Mountains’ investment in Symetra in accordance with equity accounting. During 2012, White Mountains also received cash dividends from Symetra of $2.7 million on its investment in Symetra warrants that was recorded as net investment income.

Hamer and Bri-Mar
White Mountains received equity interests in Hamer and Bri-Mar, two small manufacturing companies distributed to White Mountains in connection with the dissolution of the Tuckerman Capital, LP fund (see Note 16). Effective October 1, 2012, these investments are accounted for under the equity method. For the three months ended December 31, 2012, White Mountains recorded equity in earnings of $0.4 million for Hamer.  Bri-Mar did not have any earnings for the three months ended December 31, 2012. As of December 31, 2012, White Mountains’ investments in Hamer and Bri-Mar was $4.0 million and $1.9 million, respectively.

Pentelia
White Mountains obtained an equity interest of 33% in Pentelia Capital Management (“PCM”) for $1.6 million in April 2007. This investment is accounted for under the equity method. For the year ended December 31, 2012, 2011 and 2010, White Mountains recorded $(1.3) million, $(0.2) million, and $0.5 million of equity in earnings in PCM.  As of December 31, 2012 and 2011, White Mountains investment in PCM was $0.5 million and $1.7 million.

Delos
In August 2006, Sirius Group sold a wholly-owned subsidiary to an investor group led by Lightyear Capital for $138.8 million in cash and recognized a pre-tax gain of $14.0 million in other revenue. As part of this transaction, White Mountains acquired an equity interest of approximately 18% for $32.0 million in the acquiring entity, Delos, and accounted for its investment in Delos under the equity method. In December 2010, White Mountains sold its investment in Delos for $21.7 million and recognized a pre-tax loss of $10.9 million in other revenue.

NOTE 16. Variable Interest Entities

BAM
BAM is a newly formed mutual insurance company. As a mutual company BAM is owned by its members and a portion of each member’s charges represents a contribution to member’s surplus. During 2012, White Mountains capitalized HG Global to fund BAM through the purchase of $503.0 million of BAM Surplus Notes. The equity at risk funded by BAM’s members is not sufficient to fund its operations without the additional subordinated financial support provided by the BAM Surplus Notes and accordingly, BAM is considered to be a variable interest entity (“VIE”). The proceeds from the issuance of the BAM Surplus Notes represent substantially all of the equity at risk in BAM at December 31, 2012.
BAM and HG Global, through its wholly-owned subsidiary, HG Re, entered into a first loss reinsurance treaty (“FLRT”), under which HG Re will provide first loss protection up to 15% of par outstanding on each bond insured by BAM in exchange for 60% of the premium, net of a ceding commission, charged by BAM.  HG Re's obligations under the FLRT are satisfied by the assets in two collateral trusts: a Regulation 114 Trust and a Supplemental Trust.  Losses required to be reimbursed to BAM by HG Re are subject to an aggregate limit equal to the assets held in the collateral trusts at any point in time. In addition, HG Global has the right to designate two directors for election to BAM’s board of directors. White Mountains is required to consolidate the results of BAM. Since BAM is owned by its members, its equity and results of operations are included in non-controlling interests.

Reciprocals
Reciprocals are policyholder-owned insurance carriers organized as unincorporated associations. Each policyholder insured by the reciprocal shares risk with the other policyholders. Policyholders share profits and losses in the same proportion as the amount of insurance purchased but are not subject to assessment for net losses of the reciprocal.
OneBeacon had capitalized three reciprocals by loaning funds to them in exchange for surplus notes. In 2002, OneBeacon formed New Jersey Skylands Management LLC (“NJSM”) to provide management services for a fee to New Jersey Skylands Insurance Association, a reciprocal, and its wholly-owned subsidiary New Jersey Skylands Insurance Company (together, “New Jersey Skylands Insurance”). In 2004, OneBeacon formed Houston General Management Company to provide management services for a fee to another reciprocal, Houston General Insurance. In 2006, Adirondack AIF, LLC (“AAIF”), a wholly-owned subsidiary of OneBeacon, entered into an agreement to provide management services for a fee to Adirondack Insurance, a reciprocal. OneBeacon has no ownership interest in the reciprocals.  Under the provisions of ASC 810, OneBeacon had determined that each of the reciprocals qualifies as a VIE. Further, OneBeacon had determined that it is the primary beneficiary as it has both the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and the obligation to absorb losses or receive benefits of the entity that could potentially be significant to the VIE as a result of the management services provided to the reciprocal and the funds loaned to it. Accordingly, OneBeacon consolidates Houston General Insurance and, until the completion of the Personal Lines Transaction on July 1, 2010, consolidated New Jersey Skylands Insurance and Adirondack Insurance.
As described in Note 2, the Personal Lines Transaction, which was completed on July 1, 2010, included the sale of NJSM and AAIF and the transfer of the surplus notes issued by New Jersey Skylands Insurance and Adirondack Insurance. Completion of the Personal Lines Transaction triggered deconsolidation of New Jersey Skylands Insurance and Adirondack Insurance.
Subsequent to the Personal Lines Transaction, Houston General Insurance is OneBeacon’s only reciprocal. At December 31, 2012 and 2011, consolidated amounts related to Houston General Insurance included total assets of $97.7 million and $105.9 million, respectively, and total liabilities of $120.4 million and $126.2 million, respectively. At December 31, 2012, the net amount of capital at risk is equal to the surplus note of $23.7 million less the accumulated losses of $22.7 million which includes accrued interest on the surplus note of $19.7 million which eliminates in consolidation.

Prospector Offshore Fund
White Mountains has determined that the Prospector Offshore Fund, Ltd. (“the Prospector Fund”) is a VIE for which White Mountains is the primary beneficiary and is required to consolidate the Prospector Fund. At December 31, 2012 and 2011, White Mountains consolidated total assets of $151.0 million and $135.8 million and total liabilities of $51.1 million and $31.6 million of the Prospector Offshore Fund. In addition, at December 31, 2012 and 2011, White Mountains recorded non-controlling interest of $28.9 million and $38.9 million in the Prospector Offshore Fund. For the years ended December 31, 2012, 2011 and 2010 White Mountains recorded $2.6 million, $0.2 million and $(3.2) million of non-controlling interest income (expense) related to the Prospector Offshore Fund. At December 31, 2012, the net amount of capital at risk is equal to White Mountains’ investment in the Fund of $71.1 million, which represents White Mountains’ ownership interest of 71.1% in the Prospector Fund.
    
Tuckerman Fund I
On December 31, 2011, the Tuckerman Capital, LP fund (“Tuckerman Fund I”) was dissolved and all of the net assets of the fund were distributed to the owners of the fund, of which White Mountains owned approximately 94%. In conjunction with the dissolution, White Mountains received a portion of the shares of Hamer and Bri-Mar, two small manufacturing companies that were owned by the Tuckerman Fund I. The consolidated results of Hamer and Bri-Mar are included in the Other Operations segment from January 1, 2012 through September 30, 2012, at which point the results of these companies were no longer consolidated by White Mountains.
Prior to the dissolution, White Mountains had determined that Tuckerman Fund I was a VIE for which White Mountains was the primary beneficiary and was required to consolidate Tuckerman Fund I. At December 31, 2011, White Mountains consolidated assets of $17.6 million, liabilities of $9.9 million, non-controlling interests of $3.5 million and $2.2 million of non-controlling interest expense related to the companies distributed by Tuckerman Fund I. At December 31, 2010, White Mountains consolidated total assets of $19.4 million and total liabilities of $12.3 million of Tuckerman Fund I.  In addition, at December 31, 2010, White Mountains recorded non-controlling interest of $2.4 million in Tuckerman Fund I.  For the year ended December 31, 2010 White Mountains recorded $1.0 million of non-controlling interest expense related to Tuckerman Fund I.

Prospector
Mr. John Gillespie is the founder and Managing Member of Prospector.  Prospector serves as a discretionary adviser with respect to specified assets, primarily equity securities, managed by WM Advisors on behalf of White Mountains and other clients of WM Advisors.
Pursuant to an investment management agreement with WM Advisors (the “WMA Agreement”), Prospector charges WM Advisors fees based on the following schedule: 100 basis points on the first $200.0 million of assets under management; 50 basis points on the next $200.0 million; and 25 basis points on amounts over $400.0 million. At December 31, 2012, Prospector managed a total of $465.9 million of assets for White Mountains (excluding OneBeacon and Symetra) under this arrangement.  Prospector has a separate investment management agreement with Symetra that began on July 1, 2010.  Until that date, Symetra was a party to the WMA Agreement and subject to the above fee schedule.
Prospector has separate investment management agreements with OneBeacon (the “OneBeacon Agreements”) pursuant to which Prospector supervises and directs specified assets, primarily equity securities, including assets in OneBeacon’s defined benefit and defined contribution plans (the “ERISA Assets”).  All assets managed under the OneBeacon Agreements are subject to a single fee schedule that is substantially similar to the terms of the WMA Agreement fee schedule.  At December 31, 2012, Prospector managed $533.6 million of assets for OneBeacon under this arrangement, including $205.9 million of ERISA Assets.
During 2012, 2011 and 2010, Prospector earned $6.4 million, $6.0 million, and $6.6 million in total fees pursuant to the WMA Agreement and the OneBeacon Agreements.
Prospector also advises White Mountains on matters including capital management, asset allocation, private equity investments and mergers and acquisitions. Pursuant to a Consulting Agreement for those services, Prospector was granted 7,000 performance shares for the 2013-2015 cycle, 7,750 performance shares for the 2012-2014 cycle and 8,500 performance shares for the 2011-2013 performance cycle. In accordance with the terms of the WTM Incentive Plan, performance against target governing the performance shares will be confirmed by the Compensation Committee of the Board following the end of each performance cycle and the number of performance shares actually awarded at that time will range from 0% to 200% of the target number granted.  Based on the Company’s performance, Prospector received 49% of the 9,200 performance shares granted for the 2010-2012 performance cycle for a total payout of $2.5 million.  Unless and until the Consulting Agreement has been terminated, and subject to the approval of the Compensation Committee, at the beginning of each performance cycle Prospector is to be granted performance shares with a value of approximately $4.5 million.  The Compensation Committee establishes the performance target for such performance shares.
Pursuant to a revenue sharing agreement, Prospector has agreed to pay White Mountains 6% of the revenues in excess of $500,000 of certain of Prospector’s funds in return for White Mountains having made a founding investment in 1997.  During 2012, 2011 and 2010, White Mountains earned $0.5 million, $0.2 million, and $0.7 million under this arrangement.

F-72


At December 31, 2012, White Mountains had $117.2 million invested in limited partnership investment interests managed by Prospector (the “Funds”).  This total includes $12.9 million of OneBeacon assets.  Under the limited partnership agreements, Prospector serves as general partner and general manager of the Funds and is paid management and incentive performance fees by White Mountains and OneBeacon.  For the year ended December 31, 2012, White Mountains and OneBeacon incurred $1.1 million in management fees and $1.3 million in incentive fees.  In addition, Messrs. Barrette, Davis, Gillespie and Waters, each a director of the Company, and Mr. Campbell, an executive officer of the Company, owned limited partnership investment interests managed by Prospector as of such date.

Oakum Bay Capital
Mr. Kernan Oberting, a Managing Director of White Mountains Capital, is the Founder, Chairman of the Board and Chairman of the Risk Committee of Oakum Bay Capital (“OBC”). OBC serves as the general manager of, and owns general partnership interests in, the KVO Capital Partners (“KCP”) and the Trimarc Capital Fund (“TCF”), which are hedge funds with an aggregate of $66 million under management as of December 31, 2012. Mr. Brooke Parish, who is Mr. Oberting's brother-in-law, is the CEO of OBC. Mr. David Oberting, who is Mr. Oberting's brother, is the portfolio manager of KCP.
In connection with Mr. Oberting commencing employment with White Mountains Capital, on July 16, 2012, the Company purchased $2 million of preferred equity and received 7.5% of the common equity of OBC. The preferred equity is entitled to dividends at a rate of 5% per annum, increasing to 10% per annum after four years, and is mandatorily redeemable after six years. After giving effect to the common equity investment, Mr. Oberting and Mr. Parish beneficially owned 27.5% and 45%, respectively, of the common equity of OBC.
In addition, at the time it purchased the preferred equity in OBC, the Company invested $6 million in TCF. In 2010, the Company had invested $4 million in TCF. As of December 31, 2012, White Mountains had $9.9 million invested in TCF. Under TCF's limited partnership agreements, OBC is paid management and incentive performance fees by White Mountains.
For the year ended December 31, 2012, White Mountains paid $56,811 of management fees and $88,090 of incentive fees. OBC receives the management fees and 40% of the incentive fees. Mr. Oberting has limited partnership investments in KCP and TCF. Mr. Barrette had a limited partnership investment in KCP that was redeemed in full in September 2012.

Other Relationships and Transactions
WMA provides investment advisory and management services to Symetra.  At December 31, 2012 and 2011, WMA had $27.4 billion and $26.3 billion of assets under management from Symetra.  During 2012, 2011 and 2010, WMA earned $15.9 million, $15.2 million and $13.8 million in fees from Symetra.
On July 12, 2012, the Company repurchased 50,000 WTM common shares from John J. Byrne, a beneficial owner of the Company. The price per share was $528.45, the market price at the time the agreement was reached.
On December 19, 2012, the Company repurchased 285,000 WTM common shares from mutual funds managed by Franklin Mutual Advisers, a beneficial owner of the Company. The price per share was $519.06, the market price at the time the agreement was reached.
On January 7, 2011, the Company repurchased 140,000 WTM common shares from mutual funds managed by Franklin Mutual Advisers at a price per share of $342.50, which was $2.50 less than the market price at the time the agreement was reached.
Mr. Gillespie, a director of the Company, indirectly through general and limited partnership interests holds a 33% interest in Dowling & Partners Connecticut Fund III, LP (“Fund III”).  Two of the Company’s indirect subsidiaries, OneBeacon Professional Insurance (“OB Professional Insurance”) and White Mountains Specialty Underwriting, Inc. (“WMSUI”), had previously borrowed approximately $8.0 million and $7.0 million, respectively, from Fund III in connection with an incentive program sponsored by the State of Connecticut known as the Connecticut Insurance Reinvestment Act (the “CIR Act”).  The CIR Act provides for Connecticut income tax credits to be granted for qualifying investments made by approved fund managers.  Both loans were repaid in full during 2006.  The loans were qualifying investments which generated tax credits to be shared equally between Fund III on the one hand and OB Professional Insurance and WMSUI on the other.  As a result of his interest in Fund III, during 2009, Mr. Gillespie generated approximately $0.5 million in such tax credits.

NOTE 19. Commitments and Contingencies

White Mountains leases certain office space under non-cancellable operating leases that expired on various dates through 2021. Rental expense for all of White Mountains’ locations was $18.8 million, $22.8 million and $28.1 million for the years ended December 31, 2012, 2011 and 2010. White Mountains also has various other lease obligations that are immaterial in the aggregate.  White Mountains’ future annual minimum rental payments required under non-cancellable leases, which are primarily for office space, are $14.8 million, $13.5 million, $11.8 million, and $33.3 million for 2013, 2014, 2015 and 2016 and thereafter, respectively.
White Mountains also has future binding commitments to fund certain other-long term investments. These commitments, which total $124.7 million, do not have fixed funding dates.

Capital Lease
OBIC sold the majority of its fixed assets and capitalized software to OneBeacon Services LLC (“OB Services”) at a cost equal to book value with no gain or loss recorded on the sale. Subsequent to purchasing the fixed assets and capitalized software from OBIC, OB Services entered into lease financing arrangements with US Bancorp and Fifth Third whereby OB Services sold its furniture and equipment and its capitalized software, respectively, to US Bancorp and Fifth Third. The assets were sold at a cost equal to net book value. OB Services then leased the fixed assets back from US Bancorp for a lease term of five years and leased the capitalized software back from Fifth Third for a lease term of four years. OB Services received cash proceeds of $23.1 million as a result of entering into the sale-leaseback transactions. At the end of the lease terms, OB Services will be obligated to purchase the leased assets for a nominal fee, after which all rights, title and interest would transfer to OB Services. In accordance with ASC 840, OBIC recorded the sale of the assets with no gain or loss recognized while OB Services has recorded a capital lease obligation and a capital lease asset. As of December 31, 2012 and 2011, OB Services had a capital lease obligation of $18.2 million and $23.1 million, respectively, included within other liabilities and a capital lease asset of $16.1 million and $22.9 million included within other assets. The underlying assets will continue to be depreciated over their respective useful lives. OB Services’ future annual minimum rental payments are $5.3 million for each of the years ended December 31, 2013, 2014 and 2015 and $1.9 million for the year ended December 31, 2016.

Assigned Risks
As a condition of its license to do business in certain states, White Mountains’ insurance operations are required to participate in mandatory shared market mechanisms. Each state dictates the types of insurance and the level of coverage that must be provided. The total amount of business an insurer is required to accept is based on its market share of voluntary business in the state. In certain cases, White Mountains is obligated to write business from mandatory shared market mechanisms at some time in the future based on the market share of voluntary policies it is currently writing. Underwriting results related to assigned risk plans are typically adverse and are not subject to the predictability associated with White Mountains’ voluntarily written business.
Under existing guaranty fund laws in all states, insurers licensed to do business in those states can be assessed for certain obligations of insolvent insurance companies to policyholders and claimants. White Mountains accrues any significant insolvencies when the loss is probable and the assessment amount can be reasonably estimated. The actual amount of such assessments will depend upon the final outcome of rehabilitation proceedings and will be paid over several years. At December 31, 2012, the reserve for such assessments totaled $12.9 million.

Esurance
On October 7, 2011, the Company completed the sale of its Esurance and Answer Financial subsidiaries (the “Transferred Subsidiaries”) to Allstate pursuant a Stock Purchase Agreement dated as of May 17, 2011 (filed as an exhibit to the Company’s current report on Form 8-K on May 18, 2011, the “Agreement”). 
The Company has certain contingent liabilities under the Agreement as follows:  (i) the final purchase price payable by Allstate under the Agreement, which is based upon the book value of the Transferred Subsidiaries at the closing date, is subject to a true-up process that has not yet been concluded, (ii) subject to specified thresholds and limits, the Company generally indemnifies Allstate for breaches of its representations and warranties in the Agreement for a period of eighteen months (although longer for specified representations and warranties) from the closing, (iii) the Company indemnifies Allstate for breaches of certain covenants in the Agreement, including certain agreements by the Company not to engage in certain competing business activities for two years after the closing and not to solicit certain employees of the Transferred Subsidiaries for three years after the closing, and (iv) subject to specified thresholds and limits, the Company indemnifies Allstate for specified matters related to the pre-closing period, including (a) specified litigation matters, (b) losses of the Transferred Subsidiaries arising from extra-contractual claims and claims in excess of policy limits (“ECO/EPL losses”), (c) certain corporate reorganizations effected to remove entities from the Transferred Subsidiaries that were not being sold in the transaction, and (d) certain tax matters, including certain net operating losses being less than stated levels.  In addition, the Company retains 90% of positive or negative development in the loss reserves of the Transferred Subsidiaries as of the closing date (net of ECO/EPL losses), to be computed annually on the first three anniversaries of the closing date.

Legal Contingencies
White Mountains, and the insurance and reinsurance industry in general, are routinely subject to claims related litigation and arbitration in the normal course of business, as well as litigation and arbitration that do not arise from, or are directly related to, claims activity. White Mountains’ estimates of the costs of settling matters routinely encountered in claims activity are reflected in the reserves for unpaid loss and LAE.  See Note 3.
White Mountains considers the requirements of ASC 450 when evaluating its exposure to non-claims related litigation and arbitration.  ASC 450 requires that accruals be established for litigation and arbitration if it is probable that a loss has been incurred and it can be reasonably estimated.  ASC 450 also requires that litigation and arbitration be disclosed if it is probable that a loss has been incurred or it there is a reasonable possibility that a loss may have been incurred.

F-74


Although the ultimate outcome of claims and non-claims related litigation and arbitration, and the amount or range of potential loss at any particular time, is often inherently uncertain, management does not believe that the ultimate outcome of such claims and non-claims related litigation and arbitration will have a material adverse effect on White Mountains’ financial condition, results of operations or cash flows.
The following summarizes significant ongoing non-claims related litigation or arbitration as of December 31, 2012:

Esurance Sale
In 2011, the Company sold its Esurance and Answer Financial businesses (the “Transferred Companies”) to The Allstate Corporation (”Allstate”) for a purchase price of approximately $1.01 billion.  The purchase price consisted of $700.0 million plus the tangible book value of the Transferred Companies at the closing, which was estimated to be $308.0 million.  Following closing, Allstate was required to prepare a final closing statement, including an audited balance sheet for the Transferred Companies as of the closing date.  The Company is disputing Allstate’s calculation of tangible book value in the closing statement.  The amount in dispute is approximately $20.0 million, after tax.  The dispute principally relates to (i) the elimination of $24.7 million (pre-tax) of deferred acquisition costs ($16.0 million, after tax) and (ii) the inclusion of a liability equal to the costs associated with an Esurance extra-contractual (“ECO”) matter settled in April 2012 of $5.2 million ($3.4 million, after tax). Per the agreement governing the sale of the Transferred Companies (the “Sale Agreement”), disputes over the closing statement are to be arbitrated by an independent accountant.
The Company believes this final closing statement was required to be prepared and audited no later than January 5, 2012. Allstate did not deliver the final closing statement to the Company until June 6, 2012, with an audit report dated June 1, 2012. As a result, in addition to the substantive disputes over the final closing statement, the Company also believes that Allstate's failure to have the final closing statement prepared and audited by the required date constituted a breach of Allstate's obligations under the Sale Agreement.  The Company brought suit in the United States District Court for the Southern District of New York in connection with such breach. The court concluded that the Company’s breach claim should also be arbitrated by the independent accountant under the Sale Agreement. That process is proceeding.

Tribune Company
In June 2011, Deutsche Bank Trust Company Americas, Law Debenture Company of New York and Wilmington Trust Company (collectively referred to as “Plaintiffs”), in their capacity as trustees for certain senior notes issued by the Tribune Company (”Tribune”), filed lawsuits in various jurisdictions (the “Noteholder Actions”) against numerous defendants including OneBeacon, OBIC-sponsored benefit plans and other affiliates of White Mountains in their capacity as former shareholders of Tribune seeking recovery of the proceeds from the sale of common stock of Tribune in connection with Tribune’s leveraged buyout in 2007 (the “LBO”). Tribune filed for bankruptcy in 2008 in the Delaware bankruptcy court (the "Bankruptcy Court") and emerged from bankruptcy at the end of 2012 in a Chapter 11 reorganization.  During the bankruptcy proceedings, the Bankruptcy Court granted Plaintiffs permission to commence these LBO-related actions. Plaintiffs seek recovery of the proceeds received by the former Tribune shareholders on a theory of constructive fraudulent transfer asserting that Tribune purchased or repurchased its common shares without receiving fair consideration at a time when it was, or as a result of the purchases of shares, was rendered, insolvent. OneBeacon has entered into a joint defense agreement with other affiliates of White Mountains that are defendants in the action. Certain subsidiaries of White Mountains received approximately $39 million for Tribune common stock tendered in connection with the LBO.
        In December 2011, the Judicial Panel on Multidistrict Litigation granted a motion to consolidate all of the Noteholder Actions for pretrial matters and transfer all such proceedings to the United States District Court for the Southern District of New York.
        In addition, OneBeacon, OBIC-sponsored benefit plans and other affiliates of White Mountains in their capacity as former shareholders of Tribune, along with thousands of former Tribune shareholders, have been named as defendants in an adversary proceeding brought by the Official Committee of Unsecured Creditors of the Tribune Company, on behalf of the Tribune Company, which seeks to avoid the repurchase of shares by Tribune in the LBO on a theory of intentional fraudulent transfer (the “Committee Action”). The Committee Action has since been consolidated with the Noteholder Actions.
In September 2012, a case management order was entered in the consolidated cases, setting forth, among other things, a briefing schedule for an omnibus motion to dismiss in the Noteholder Actions. The court is expected to hear oral argument on that motion in March 2013. Discovery and other motion practice (other than motions to amend the complaints) in the Committee Action and the Noteholder Actions is stayed until further order of the court.

F-75


 Ace American Insurance Company
A subsidiary of OneBeacon, OBH, was sued in Federal Court in the Eastern District of Pennsylvania on August 17, 2012 by Ace American Insurance Company (“Ace”).  The complaint alleges that OBH, through a professional recruiting firm, improperly hired a group of Ace employees from Ace's surety division.  The complaint sought injunctive relief and unspecified damages. After court-ordered expedited discovery was completed, the claims for injunctive relief were resolved pursuant to a confidential agreement.  The remaining claim against OBH is for damages only and is scheduled to be heard in April.  After the claims against OBH for injunctive relief were resolved, Ace filed a Demand for Arbitration against five of the former Ace surety employees hired by OneBeacon, alleging breach of their duty of loyalty to Ace and misappropriation of Ace trade secrets.  OneBeacon believes that Ace's damages claim against OBH and the claims against the individual employees are without merit and intends to vigorously defend both.

NOTE 20. Discontinued Operations

Esurance
On October 7, 2011, White Mountains completed the sale of Esurance Insurance and AFI to Allstate (see Note 2).  As a result of the transaction, Esurance Insurance, AFI and the business Esurance Insurance cedes to Sirius Group (collectively, “the Esurance Disposal Group”) are reported as discontinued operations.  White Mountains recognized a gain of $677.5 million on the Esurance Sale which is recorded net of tax in discontinued operations.  Effective as of December 31, 2011, the results of operations for the Esurance Disposal Group have been classified as discontinued operations and are presented, net of related income taxes, in the statement of comprehensive income.

AutoOne
 On February 22, 2012, OneBeacon completed the sale of the AutoOne business to Interboro. AutoOne operated as a division within OneBeacon that offered products and services to automobile assigned risk markets. The transaction included the sale of two insurance entities, AOIC and AOSIC, through which substantially all of the AutoOne business was written on a direct basis. The results of operations for the AutoOne business have been classified as discontinued operations and are presented, net of related income taxes, in the statement of comprehensive income. The assets and liabilities associated with the AutoOne business as of December 31, 2011 have been presented in the balance sheet as held for sale.
During 2012, OneBeacon and Interboro finalized the post-closing adjustments to the closing balance sheet resulting in OneBeacon recording a net gain of $0.5 million after tax. This after-tax net gain is included in loss from sale of discontinued operations in the statements of comprehensive income (loss) for the year ended December 31, 2012. During 2011, OneBeacon recorded an after-tax loss of $19.2 million in loss from sale of discontinued operations for the estimated loss on sale of AutoOne.

Runoff Transaction
 On October 17, 2012, OneBeacon entered into an agreement to sell its runoff business to Armour. During 2012, the results of operations for the runoff business have been classified as discontinued operations and are presented, net of related income taxes, in the statement of comprehensive income. Prior year results of operations have been reclassified to conform to the current period’s presentation. The assets and liabilities associated with the runoff business as of December 31, 2012 have been presented in the balance sheet as held for sale. The amounts classified as discontinued operations exclude investing and financing activities that are conducted on an overall consolidated level and, accordingly, there were no separately identifiable investments associated with the runoff business. Therefore, the prior period balance sheet has not been reclassified to conform to the current period’s presentation.
For the year ended December 31, 2012, White Mountains recorded a $91.5 million after-tax loss on sale and a $24.0 million loss from operations which included a $9.0 million after-tax loss related to an reduction in the workers compensation loss reserve discount rate on reserves being transferred as part of the sale.
 

F-76


Loss and LAE reserve development. During 2012, OneBeacon experienced $40.0 million of net unfavorable loss reserve development from the runoff business. The net unfavorable loss reserve development was primarily related to related to case incurred development on multiple peril liability and general liability claims and the impact of an adverse court ruling in Mississippi regarding a disputed assessment from an involuntary pool for hurricane Katrina claims. In addition, there was a change in the workers' compensation tabular discount rate from 4.5% to 3.5% that resulted in a charge of $15.2 million.
During 2011, OneBeacon experienced $26.7 million of net unfavorable loss reserve development from the runoff business. The net unfavorable loss reserve development resulted from a detailed review of runoff expenses, principally unallocated loss adjustment expenses (“ULAE”), completed during the fourth quarter of 2011. Specifically, OneBeacon completed a detailed review of loss and defense and cost containment expenses (allocated LAE or “ALAE”) and other adjusting expenses (ULAE) during the fourth quarter of 2011. The analysis considered costs, based on current non-staff expenses and staffing projections for the runoff business, as OneBeacon continued efforts to segregate its claims operations between ongoing claims and runoff claims. The analysis also factored in the revised definition of runoff claims to include the non-specialty commercial lines business that was exited via the renewal rights agreement sale beginning with January 1, 2010 effective dates.
During 2010, OneBeacon experienced $23.1 million of net favorable loss reserve development from the runoff business. The net favorable loss reserve development was primarily due to lower than expected severity on multiple peril liability lines and other general liability lines, particularly for accident years 2004 through 2009. As a result of the lower than expected case incurred loss and ALAE, actuarial methods based on case incurred losses produced lower estimated ultimate losses, resulting in lower estimates of required IBNR.
 
Reinsurance. Included in the assets held for sale are reinsurance recoverables from two reinsurance contracts with subsidiaries of Berkshire Hathaway Inc. that OneBeacon was required to purchase in connection with White Mountains’ acquisition of OneBeacon in 2001: a reinsurance contract with National Indemnity Company (“NICO”) for up to $2.5 billion in old asbestos and environmental (“A&E”) claims and certain other exposures (the “NICO Cover”) and an adverse loss reserve development cover from General Reinsurance Corporation (“GRC”) for up to $570.0 million, comprised of $400.0 million of adverse loss reserve development occurring in years 2000 and prior in addition to $170.0 million of reserves ceded as of the date of the OneBeacon Acquisition (the “GRC Cover”) . The NICO Cover and GRC Cover, which were contingent on and occurred contemporaneously with the OneBeacon Acquisition, were put in place in lieu of a seller guarantee of loss and LAE reserves and are therefore accounted for under GAAP as a seller guarantee. As of December 31, 2012, the total reinsurance recoverable on paid and unpaid losses of $1,401.9 million related to both the NICO cover and the GRC cover has been included in assets held for sale. Both NICO and GRC have an A.M Best rating of A++, Superior, which is the highest of fifteen ratings.
The total reinsurance recoverables on paid and unpaid losses in assets held for sale were $15.6 million and $1,840.8 million as of December 31, 2012. The reinsurance recoverable on unpaid amount is gross of $150.1 million in purchase accounting adjustments that will become recoverable if claims are paid in accordance with current reserve estimates. In addition, $36.7 million of the amount that is currently included in assets held for sale on the balance sheet will be reported in reinsurance recoverables on unpaid losses when the Runoff Transaction closes (at the then current value) as a result of a related reinsurance contract.

Asbestos and environmental loss and LAE reserve activity. OneBeacon's reserves include provisions made for claims that assert damages from A&E related exposures. Substantially all of these reserves have been reclassified to liabilities held for sale as of December 31, 2012, as they relate to the runoff business. Asbestos claims relate primarily to injuries asserted by those who came in contact with asbestos or products containing asbestos. Environmental claims relate primarily to pollution and related clean-up obligations, particularly as mandated by Federal and state environmental protection agencies. In addition to the factors regarding the reserving process, OneBeacon estimates its A&E reserves based upon, among other factors, facts surrounding reported cases and exposures to claims, such as policy limits and deductibles, current law, past and projected claim activity and past settlement values for similar claims, as well as analysis of industry studies and events, such as recent settlements and asbestos-related bankruptcies. The cost of administering A&E claims, which is an important factor in estimating loss reserves, tends to be higher than in the case of non-A&E claims due to the higher legal costs typically associated with A&E claims.
OneBeacon's reserves for A&E losses at December 31, 2012 represent management's best estimate of its ultimate liability based on information currently available. However, significant uncertainties, including but not limited to case law developments, medical and clean up cost increases and industry settlement practices, limit OneBeacon's ability to accurately
estimate ultimate liability and OneBeacon may be subject to A&E losses beyond currently estimated amounts. In addition,
OneBeacon remains liable for risks reinsured in the event that a reinsurer does not honor its obligations under reinsurance
contracts. OneBeacon cannot reasonably estimate at the present time loss reserve additions arising from any such future adverse loss reserve developments and cannot be sure that allocated loss reserves, plus the remaining capacity under the NICO Cover and other reinsurance contracts, will be sufficient to cover additional liability arising from any such adverse loss reserve
developments.
The following tables summarize reported A&E loss and LAE reserve activities (gross and net of reinsurance) for
OneBeacon for the years ended December 31, 2012, 2011 and 2010, respectively.

Earnings (Loss) Per Share
Basic earnings (loss) per share amounts are based on the weighted average number of common shares outstanding including unvested restricted shares that are considered participating securities.  Diluted earnings (loss) per share amounts are based on the weighted average number of common shares including unvested restricted shares and the net effect of potentially dilutive common shares outstanding.  The following table outlines the computation of earnings (loss) per share for discontinued operations for the years ended December 31, 2012, 2011 and 2010:

Restricted shares issued by White Mountains contain dividend participation features, and therefore, are considered participating securities.

NOTE 21. Subsequent Event

Sale of Essentia
On January 2, 2013, OneBeacon completed the sale of Essentia Insurance Company (“Essentia”), an indirect wholly owned subsidiary that wrote policies for the Hagerty collector car and boat business, to Markel Corporation. OneBeacon will recognize a pre-tax gain on sale of approximately $23 million ($15 million after tax) in the first quarter of 2013. The Hagerty business associated with this agreement generated net written premiums of approximately $179.7 million, $166.6 million and $153 million (8.0% of WhiteMountains’ consolidated written premiums for all periods), for the years ended December 31, 2012, 2011 and 2010.

MANAGEMENT’S RESPONSIBILITY FOR FINANCIAL STATEMENTS
 
Management is responsible for the preparation and fair presentation of the financial statements included in this report.  The financial statements have been prepared in conformity with GAAP in the United States.  The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.
The Audit Committee of the Board, which is comprised entirely of independent, qualified directors, is responsible for the oversight of our accounting policies, financial reporting and internal control including the appointment and compensation of our independent registered public accounting firm.  The Audit Committee meets periodically with management, our independent registered public accounting firm and our internal auditors to ensure they are carrying out their responsibilities.  The Audit Committee is also responsible for performing an oversight role by reviewing our financial reports.  Our independent registered public accounting firm and internal auditors have full and unlimited access to the Audit Committee, with or without management present, to discuss the adequacy of internal control over financial reporting and any other matters which they believe should be brought to their attention.

MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
 
Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934.  There are inherent limitations in the effectiveness of any internal control over financial reporting, including the possibility of human error and the circumvention or overriding of internal control.  Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation.  Further, an effective internal control environment as of a point in time may become inadequate in the future because of changes in conditions, or deterioration in the degree of compliance with the policies and procedures.
We assessed the effectiveness of White Mountains' internal control over financial reporting as of December 31, 2012. Our assessment did not include an assessment of the internal control over financial reporting for certain recent acquisitions. These acquisitions were Physicians Insurance Company of Ohio, Citation Insurance Company, American General Indemnity Company and American General Property Insurance Company which combined represent less than 1% of White Mountains' total assets as of December 31, 2012 and less than 1% of White Mountains' total revenue for the year ended December 31, 2012. In making our assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on this assessment, we have concluded that White Mountains maintained effective internal control over financial reporting as of December 31, 2012.
PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm, has audited the effectiveness of White Mountains’ internal control over financial reporting as of December 31, 2012 as stated in their report which appears on page F-82.

Report of Independent Registered Public Accounting Firm
 
To the Board of Directors and Shareholders of White Mountains Insurance Group, Ltd.:

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of White Mountains Insurance Group, Ltd. and its subsidiaries (the "Company") at December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedules listed in the accompanying index present fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedules, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on these financial statements, on the financial statement schedules, and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As described in Management's Annual Report on Internal Control Over Financial Reporting, management has excluded Physicians Insurance Company of Ohio, Citation Insurance Company, American General Indemnity Company and American General Property Insurance Company from its assessment of internal control over financial reporting as of December 31, 2012 because the entities were recently acquired by the Company. We have also excluded Physicians Insurance Company of Ohio, Citation Insurance Company, American General Indemnity Company and American General Property Insurance Company from our audit of internal control over financial reporting. Physicians Insurance Company of Ohio, Citation Insurance Company, American General Indemnity Company and American General Property Insurance Company are wholly-owned subsidiaries whose combined total assets and combined total revenues represent less than 1% and 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2012.

SELECTED QUARTERLY FINANCIAL DATA
(Unaudited)
 
Selected quarterly financial data for 2012 and 2011 is shown in the following table. The quarterly financial data includes, in the opinion of management, all recurring adjustments necessary for a fair presentation of the results of operations for the interim periods. As a result of the Esurance Sale and AutoOne Sale, the results of operations for Esurance and AutoOne have been classified as discontinued operations and are now presented, net of related income taxes, as such in the statement of comprehensive income. Prior year amounts have been reclassified to conform to the current period’s presentation (see Note 20).

The amounts shown represent OneBeacon’s discount on its long-term workers compensation loss and LAE reserves, as such liabilities constitute unpaid but settled claims under which the payment pattern and ultimate costs are fixed and determinable on an individual basis. OneBeacon discounts these reserves using a discount rate which is determined based on the facts and circumstances applicable at the time the claims are settled (3.5%, 4.5% and 5.0% at December 31, 2012, 2011 and 2010). Also the amounts shown include unamortized fair value adjustments to reserves for unpaid claims and claims adjustment expenses made in purchase accounting as a result of White Mountains’ purchase of OneBeacon for the years ended December 31, 2012, 2011 and 2010.
(2) 
The amount shown represents unamortized fair value adjustments to reserves for unpaid claims and claims adjustment expenses made in purchase accounting as a result of White Mountains’ purchase of Sirius International during 2004.
