NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Note 1. Summary of Significant Accounting Policies

Basis of Presentation

These interim 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 insurance subsidiaries and other affiliates. The Company’s headquarters is located at 26 Reid 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’s reportable segments are HG Global/BAM, MediaAlpha and Other Operations.

The HG Global/BAM segment consists of HG Global Ltd. and its wholly-owned subsidiaries (“HG Global”) and the consolidated results of Build America Mutual Assurance Company (“BAM”). BAM is the first and only mutual bond insurance company in the United States. By insuring the timely payment of principal and interest, BAM provides market access to, and lowers interest expense for, issuers of municipal bonds used to finance essential public purposes such as schools, utilities and transportation facilities. BAM is owned by and operated for the benefit of its members, the municipalities that purchase BAM’s insurance for their debt issuances. HG Global was established to fund the startup of BAM and, through its wholly-owned subsidiary, HG Re Ltd. (“HG Re”), to provide 15%-of-par, first loss reinsurance protection for policies underwritten by BAM. HG Global, together with its subsidiaries, provided the initial capitalization of BAM through the purchase of $503.0 million of surplus notes issued by BAM (the “BAM Surplus Notes”). As of June 30, 2017 and December 31, 2016, White Mountains owned 96.9% of HG Global’s preferred equity and 88.4% of its common equity. White Mountains does not have an ownership interest in BAM. However, GAAP requires White Mountains to consolidate BAM’s results in its financial statements. BAM’s results are attributed to non-controlling interests.

The MediaAlpha segment consists of QL Holdings LLC and its wholly-owned subsidiary QuoteLab, LLC (collectively “MediaAlpha”). MediaAlpha is an advertising technology company that develops transparent and efficient platforms for the buying and selling of insurance and other vertical-specific performance media (i.e., clicks, calls and leads). MediaAlpha’s exchange technology, machine learning and analytical tools facilitate transparent, real-time transactions between advertisers (buyers of advertising inventory) and publishers (sellers of advertising inventory). MediaAlpha works with over 300 advertisers and 225 publishers across a number of insurance (auto, motorcycle, home, renter, health and life) and non-insurance (travel, education, personal finance and home services) verticals.

White Mountains’s Other Operations segment consists of the Company and its intermediate holding companies, its wholly-owned investment management subsidiary, White Mountains Advisors LLC (“WM Advisors”) and certain consolidated and unconsolidated private capital investments. The consolidated private capital investments consist of Wobi Insurance Agency Ltd. (“Wobi”) and Removal Stars Ltd. (“Buzzmove”). White Mountains’s Other Operations segment also includes its variable annuity reinsurance business, White Mountains Life Reinsurance (Bermuda) Ltd. (“Life Re Bermuda”), which completed its runoff with all of its contracts fully matured on June 30, 2016, and its U.S.-based service provider, White Mountains Financial Services LLC (collectively, “WM Life Re”).

On May 2, 2017, OneBeacon Insurance Group, Ltd. (“OneBeacon Ltd.”) entered into a definitive agreement to be acquired by Intact Financial Corporation (“Intact”), which is expected to close in the third or fourth quarter of 2017 (the “OneBeacon Transaction”). OneBeacon Ltd., an exempted Bermuda limited liability company that owns a family of property and casualty insurance companies (collectively, “OneBeacon”), offers a wide range of insurance products in the United States through independent agencies, regional and national brokers, wholesalers and managing general agencies. On July 21, 2016, White Mountains completed its sale of Tranzact Holdings, LLC (“Tranzact”) to an affiliate of Clayton, Dubilier & Rice, LLC. On April 18, 2016, White Mountains completed its sale of Sirius International Insurance Group, Ltd., and its subsidiaries (collectively, “Sirius Group”) to CM International Holding PTE Ltd. (“CMI”), the Singapore-based investment arm of China Minsheng Investment Corp., Ltd. White Mountains has presented the results of OneBeacon, Tranzact and Sirius Group as discontinued operations in the statement of operations and comprehensive income for all periods prior to each transaction’s completion date. White Mountains has presented OneBeacon’s assets and liabilities as held for sale as of June 30, 2017 and December 31, 2016. On March 7, 2017, White Mountains completed the sale of Star & Shield Services LLC, Star & Shield Risk Management LLC, and Star & Shield Claims Services LLC (collectively “Star & Shield”) and its investment in Star & Shield Insurance Exchange (“SSIE”) surplus notes to K2 Insurance Services, LLC. Star & Shield provides management services for a fee to SSIE, a reciprocal that is owned by its members, who are policyholders. White Mountains was required to consolidate SSIE in its GAAP financial statements until White Mountains completed the sale. White Mountains has presented Star & Shield’s and SSIE’s assets and liabilities as held for sale as of December 31, 2016. See Note 15 — “Held for Sale and Discontinued Operations”.

All significant intercompany transactions have been eliminated in consolidation. Certain amounts in the prior period financial statements have been reclassified to conform to the current presentation. These interim financial statements include all adjustments considered necessary by management to fairly state the financial position, results of operations and cash flows of White Mountains. These interim financial statements may not be indicative of financial results for the full year and should be read in conjunction with the Company’s 2016 Annual Report on Form 10-K.

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. Refer to the Company’s 2016 Annual Report on Form 10-K for a complete discussion regarding White Mountains’s significant accounting policies.

Recently Adopted Changes in Accounting Principles

Stock Compensation

Effective January 1, 2017, White Mountains adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (ASC 718) which simplifies certain aspects of the accounting for share-based compensation. The new guidance provides an accounting policy election to account for forfeitures by either applying an assumption, as required under existing guidance, or by recognizing forfeitures when they actually occur. At adoption, White Mountains did not change its accounting policy for forfeitures, which is to apply an assumed forfeiture rate. The new guidance has also changed the threshold for partial cash settlement to settle statutory withholding requirements for equity classified awards, increasing the threshold up to the maximum statutory tax rate. As a result of adoption, White Mountains reported $9.2 million and $5.8 million of statutory withholding tax payments made in connection with the settlement of restricted shares as financing cash flows for the six-month periods ended June 30, 2017 and 2016. Such payments were classified as operating cash flows prior to adoption.

In addition, the new guidance changed the treatment for excess tax benefits which arise from the difference between the deduction for tax purposes and the compensation costs recognized for financial reporting. Under the new guidance, a reporting entity will recognize excess tax benefits or expense in current period earnings, regardless of whether it is in a taxes payable position.

Business Combinations - Measurement Period Adjustments

Effective January 1, 2016, White Mountains adopted ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, which requires adjustments to provisional amounts recorded in connection with a business combination that are identified during the measurement period to be recorded in the reporting period in which the adjustment amounts are determined, rather than as retroactive adjustments to prior periods. White Mountains has not recognized any adjustments to estimated purchase accounting amounts for the year to date period ended June 30, 2017 and accordingly, there was no effect to White Mountains’s financial statements upon adoption.

Amendments to Consolidation Analysis

On January 1, 2016, White Mountains adopted ASU 2015-02, Amendments to the Consolidation Analysis (ASC 810) which amends the guidance for determining whether an entity is a variable interest entity (“VIE”). ASU 2015-02 eliminates the separate consolidation guidance for limited partnerships and, with it, the presumption that a general partner should consolidate a limited partnership. In addition, ASU 2015-02 changes the guidance for determining if fee arrangements qualify as variable interests and the effect fee arrangements have on the determination of the primary beneficiary. Adoption of ASU 2015-02 did not affect the consolidation analysis for any of White Mountains’s investments.

Share-Based Compensation Awards

On January 1, 2016, White Mountains adopted ASU 2014-12, Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASC 718). The new guidance requires that a performance target that affects vesting and that can be achieved after the requisite service period be treated as a performance condition. Compensation cost is to be recognized in the period when it becomes probable the performance target will be achieved in an amount equal to the compensation cost attributable to the periods for which service has been rendered. Adoption did not have any effect on White Mountains’s financial position, results of operations, cash flows, presentation or disclosures.

Debt Issuance Costs

On January 1, 2016, White Mountains adopted ASU 2015-03, Imputation of Interest (ASC 835), which requires debt issuance costs to be presented as a deduction from the carrying amount of the related debt, consistent with the treatment required for debt discounts. The new guidance requires amortization of debt issuance costs to be classified within interest expense and also requires disclosure to the debt’s effective interest rate. As of June 30, 2017, there was an insignificant amount of unamortized debt issuance costs included in debt.

Recently Issued Accounting Pronouncements

Stock Compensation

In May 2017, the FASB issued ASU 2017-09, Stock Compensation: Scope of Modification Accounting (ASC 718), which narrows the scope of transactions subject to modification accounting to changes in terms of an award that result in a change in the award’s fair value, vesting conditions or classification. The new guidance becomes effective for fiscal years beginning after December 15, 2017.

Cash Flow Statement

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (ASC 230), which addresses the classification and presentation of certain items, including debt prepayment and extinguishment costs, contingent consideration payments made after a business combination and distributions received from equity method investees, for which there was diversity in practice.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash (ASC 230). Under current guidance, restricted amounts of cash or cash equivalents are excluded from the cash flow statement. The new guidance requires restricted cash and restricted cash equivalents to be included in the reconciliation of beginning and end-of-period amounts presented on the statement of cash flows. In addition, the new guidance requires a description of the nature of the changes in restricted cash and cash equivalents during the periods presented.

The updated guidance in ASU 2016-15 and ASU 2016-18 are both effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. White Mountains is evaluating the expected impact of this new guidance.

Credit Losses

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (ASC 326), which establishes new guidance for the recognition of credit losses for financial assets measured at amortized cost. The new ASU requires reporting entities to estimate the credit losses expected over the life of a credit exposure using historical information, current information and reasonable and supportable forecasts that affect the collectability of the financial asset. This differs from current U.S. GAAP, which delays recognition until it is probable a loss has been incurred. The new guidance is expected to accelerate recognition of credit losses. The types of assets within the scope of the new guidance include premium receivables, reinsurance recoverables and loans. ASU 2016-13 is effective for annual periods beginning after January 1, 2020, including interim periods. White Mountains is evaluating the expected impact of this new guidance.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842). The new guidance requires lessees to recognize lease assets and liabilities on the balance sheet for both operating and financing leases, with the exception of leases with an original term of 12 months or less. Under existing guidance recognition of lease assets and liabilities is not required for operating leases. The lease assets and liabilities to be recognized are both measured initially based on the present value of the lease payments. Under the new guidance, a sale-leaseback transaction must meet the recognition criteria under ASC 606, Revenues in order to be accounted for as sale. The new guidance is effective for White Mountains for years beginning after December 15, 2018, including interim periods therein. White Mountains is evaluating the expected impact of this new guidance and available adoption methods.

Financial Instruments - Recognition and Measurement

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (ASC 825-10). The new ASU modifies the guidance for financial instruments, including investments in equity securities. Under the new guidance, all equity securities with readily determinable fair values are required to be measured at fair value with changes therein recognized through current period earnings. In addition, the new ASU requires a qualitative assessment for equity securities without readily determinable fair values to identify impairment, and for impaired equity securities to be measured at fair value. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, with early adoption permitted. White Mountains measures its portfolio of investment securities at fair value with changes therein recognized through current period earnings and accordingly, does not expect the adoption of ASU 2016-01 to have a significant impact on its financial statements.

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606), which modifies the guidance for revenue recognition. Under ASU 2014-09, revenue is to be recognized at an amount that reflects the consideration to which an entity expects to be entitled in exchange for goods or services transferred to customers. The new guidance sets forth the steps to be followed to recognize revenue: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. Subsequently, the FASB issued additional ASUs clarifying the guidance in and providing implementation guidance for ASU 2014-09.

In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers, which delays the effective date of ASU 2014-09 and all related ASUs to annual and interim reporting periods beginning after December 15, 2017. Revenue from insurance contracts, investment income and investments gains and losses are excluded from the scope of 2014-09. The new guidance is applicable to some of White Mountains’s revenue streams, including certain fee arrangements as well as commissions and other non-insurance revenues. White Mountains is evaluating the new guidance, but does not expect ASU 2014-09 to have a significant effect on recognition of White Mountains’s revenues from customers.

Note 2. Significant Transactions

Sale of OneBeacon

On May 2, 2017, OneBeacon Ltd. entered into a definitive agreement to be acquired by Intact in an all-cash transaction for $18.10 per share, or roughly 1.65x tangible book value. White Mountains owns 75.7% of OneBeacon’s outstanding common shares, representing 96.9% of the voting power as of June 30, 2017. On July 18, 2017, White Mountains voted its shares of OneBeacon Ltd. in favor of the OneBeacon Transaction. White Mountains expects to receive gross proceeds of $1.3 billion from the OneBeacon Transaction, which is expected to close in the third or fourth quarter of 2017 and is subject to regulatory approval and other customary closing conditions. The results of OneBeacon have been presented as discontinued operations in the statement of operations and comprehensive income for all periods and OneBeacon’s assets and liabilities have been presented as held for sale as of June 30, 2017 and December 31, 2016. As the OneBeacon Transaction was set at a fixed price, the results of OneBeacon do not impact White Mountains’s adjusted book value per share including the estimated gain from the transaction between signing and closing. See Note 15 — “Held for Sale and Discontinued Operations”.

Sale of Star & Shield

On March 7, 2017, White Mountains completed its sale of Star & Shield and its investment in SSIE surplus notes to K2 Insurances LLC. White Mountains did not recognize any gain or loss on the sale. Through December 31, 2016, Star & Shield’s assets and liabilities are reported as held for sale within White Mountains’s GAAP financial statements. See Note 15 — “Held for Sale and Discontinued Operations”.

Acquisition of Buzzmove

On August 4, 2016, White Mountains acquired a 70.9% ownership share in Buzzmove for a purchase price of GBP 6.1 million (approximately $8.1 million based upon the foreign exchange spot rate at the date of acquisition). White Mountains recognized total assets acquired related to Buzzmove of $11.5 million, including $7.6 million of goodwill and $1.1 million of intangible assets, and total liabilities assumed of $0.1 million, reflecting acquisition date fair values.

Sale of Tranzact

On July 21, 2016, White Mountains completed the sale of Tranzact to Clayton, Dubilier & Rice, LLC and received net proceeds of $221.3 million. In connection with the sale of Tranzact, the purchaser directly repaid $56.3 million for the portion of Tranzact’s debt attributable to White Mountains’s common shareholders. On October 5, 2016, White Mountains received additional proceeds of $1.2 million following the release of the post-closing purchase price adjustment escrow.

White Mountains recorded a $51.9 million gain from the sale of Tranzact in discontinued operations, which included a $30.2 million tax expense for the reversal of a tax valuation allowance that is offset by a tax benefit recorded in continuing operations. See Note 6 — “Income Taxes”. The increase to White Mountains’s book value from the sale of Tranzact was $82.1 million. A reconciliation of the gain reported in discontinued operations to the impact to White Mountains’s book value is as follows:



Gain from sale of Tranzact reported in discontinued operations	$	51.9
Add back reclassification from continuing operations for the release of a tax valuation allowance	30.2
Increase to White Mountains’s book value from sale of Tranzact	$	82.1

In the first quarter of 2017, White Mountains recorded a $1.0 million reduction to the gain from sale of Tranzact in discontinued operations as a result of state tax expense.

Through July 21, 2016, Tranzact’s results of operations are reported as discontinued operations and assets and liabilities held for sale within White Mountains’s GAAP financial statements. See Note 15 — “Held for Sale and Discontinued Operations”.

Sale of Sirius Group

On April 18, 2016, White Mountains completed the sale of Sirius Group to CMI for approximately $2.6 billion. $161.8 million of this amount was used to purchase certain assets to be retained by White Mountains out of Sirius Group, including shares of OneBeacon. The amount paid at closing was based on an estimate of Sirius Group’s closing date tangible common shareholder’s equity. During the third quarter of 2016, there was a final true-up to Sirius Group’s tangible common shareholder’s equity that resulted in a $4.0 million reduction to the gain. During 2016, White Mountains recorded $363.2 million of gain from sale of Sirius Group in discontinued operations and $113.3 million in other comprehensive income from discontinued operations from Sirius Group.

During the second quarter of 2017, White Mountains recorded a $0.6 million reduction to the gain from sale of Sirius Group as a result of a change to the valuation of the accrued incentive compensation payable to Sirius Group employees.

Through April 18, 2016, Sirius Group’s results are reported as discontinued operations and assets and liabilities held for sale within White Mountains’s GAAP financial statements.

The transactions to purchase the investments in OneBeacon and the other investments held by Sirius Group prior to the closing are presented in the statement of cash flows as net settlement of investment cash flows within discontinued operations. See Note 15 — “Held for Sale and Discontinued Operations”.

Sale of Symetra

On February 1, 2016, Symetra Financial Corporation (“Symetra”) closed its merger agreement with Sumitomo Life Insurance Company (“Sumitomo Life”) and White Mountains received proceeds of $658.0 million, or $32.00 per common share. White Mountains also received a special dividend of $0.50 per share as part of the transaction that was paid in the third quarter of 2015. See Note 12 — “Investment in Symetra”.

Note 3. Investments Securities

White Mountains’s portfolio of investment securities held for general investment purposes consists of fixed maturity investments, short-term investments, common equity securities, and other-long term investments, which are all classified as trading securities. Trading securities are reported at fair value as of the balance sheet date. Net realized and unrealized investment gains (losses) on trading securities are reported in pre-tax revenues.

White Mountains’s fixed maturity investments are generally valued using industry standard pricing methodologies. Key inputs include benchmark yields, benchmark securities, reported trades, issuer spreads, bids, offers, credit ratings and prepayment speeds. Income on mortgage 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.

Realized investment gains (losses) resulting from sales of investment securities are accounted for using the specific identification method. Premiums and discounts on all fixed maturity investments are amortized or accreted to income over the anticipated life of the investment. Short-term investments consist of interest-bearing 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 or accreted cost, which approximated fair value as of June 30, 2017 and December 31, 2016.

Other long-term investments consist primarily of hedge funds, private equity funds and unconsolidated private capital investments.

Net Investment Income

White Mountains’s net investment income is comprised primarily of interest income associated with White Mountains’s fixed maturity investments and short-term investments and dividend income from its common equity securities and other long- term investments.

⁽²⁾White Mountains holds a 20% ownership interest in OneTitle Holdings LLC (“OTH”) and has provided a $10.0 million surplus note facility under which OTH’s wholly-owned insurance subsidiary, OneTitle National Guaranty Company, Inc. may, under certain circumstances, draw funds. At June 30, 2017, no funds had been drawn on the surplus note facility.

Hedge Funds and Private Equity Funds

White Mountains holds investments in hedge funds and private equity funds, which are included in other long-term investments. The fair value of these investments is generally estimated using the net asset value (“NAV”) of the funds. As of June 30, 2017, White Mountains held investments in two hedge funds and eight private equity funds. The largest investment in a single fund was $53.8 million as of June 30, 2017 and $21.5 million as of December 31, 2016. The following table summarizes investments in hedge funds and private equity funds by investment objective and sector as of June 30, 2017 and December 31, 2016:

Redemption of investments in certain hedge funds is subject to restrictions including lock-up periods where no redemptions or withdrawals are allowed, restrictions on redemption frequency and advance notice periods for redemptions. Amounts requested for redemptions remain subject to market fluctuations until the redemption effective date, which generally falls at the end of the defined redemption period. As of June 30, 2017, one hedge fund with a fair value of $53.8 million was subject to a lock-up period that expires on September 1, 2018.

The following summarizes the June 30, 2017 fair value of hedge funds subject to restrictions on redemption frequency and advance notice period requirements for investments in active hedge funds:



	Notice Period

Total	$	53.8	$	18.3	$	72.1

As of June 30, 2017, White Mountains did not have any redemption requests outstanding for investments in active hedge funds that would be subject to market fluctuations. Redemption requests are recorded as a receivable when the hedge fund investment is 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.

As of June 30, 2017, investments in private equity funds were subject to lock-up periods as follows:



Millions	1-3 years	3 – 5 years	5 – 10 years	>10 years	Total
Private Equity Funds — expected lock-up period remaining	$3.6	$20.9	$29.7	$22.2	$76.4

Fair value measurements as of June 30, 2017

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 or liabilities 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”). As of June 30, 2017 and December 31, 2016, White Mountains used quoted market prices or other observable inputs to determine fair value for approximately 91% and 94% of its investment portfolio. Investments valued using Level 1 inputs include fixed maturity investments, primarily investments in U.S. Treasuries, short-term investments, which include U.S. Treasury Bills and common equity securities. Investments valued using Level 2 inputs are primarily comprised of fixed maturity investments, which have been disaggregated into classes, including debt securities issued by corporations, mortgage and asset-backed securities, municipal obligations, and foreign government, agency and provincial obligations. Investments valued using Level 2 inputs also include certain passive exchange traded funds (“ETFs”) that track U.S. stock indices such as the S&P 500 but are traded on foreign exchanges and that management values using the fund manager’s published NAV to account for the difference in market close times. 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’s investments in certain fixed maturity investments, equity securities and other long-term investments where quoted market prices are unavailable or are not considered reasonable. Transfers between levels are based on investments held as of the beginning of the period.

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 White Mountains uses have indicated that they will only provide prices where observable inputs are available. In circumstances where quoted market prices are unavailable or are not considered reasonable, White Mountains estimates the fair value using industry standard pricing methodologies and observable inputs such as benchmark yields, reported trades, broker-dealer quotes, issuer spreads, benchmark securities, bids, offers, credit ratings, prepayment speeds, reference data including research publications and other relevant inputs. Given that many fixed maturity investments do not trade on a daily basis, the outside pricing services evaluate a wide range of fixed maturity investments by regularly drawing parallels from recent trades and quotes of comparable securities with similar features. The characteristics used to identify comparable fixed maturity investments vary by asset type and take into account market convention.

White Mountains’s process to assess the reasonableness of the market prices obtained from the outside pricing sources

covers substantially all of its fixed maturity investments and includes, but is not limited to, the evaluation of pricing methodologies and a review of the pricing services’ quality control processes and procedures on at least an annual basis, a comparison of its invested asset prices obtained from alternate independent pricing vendors on at least a semi-annual basis, monthly analytical reviews of certain prices and a review of the underlying assumptions utilized by the pricing services for select 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 $1.0 million from the expected price based on these assessment procedures are considered outliers. Also considered outliers are prices that have not changed from period to period and prices that have trended unusually compared to market conditions. In circumstances where the results of White Mountains’s review process does not appear to support the market price provided by the pricing services, White Mountains challenges the vendor provided 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 valuation process described above is generally applicable to all of White Mountains’s fixed maturity investments. The techniques and inputs specific to asset classes within White Mountains’s fixed maturity investments for Level 2 securities that use observable inputs are as follows:

Debt securities issued by corporations: The fair value of debt securities issued by corporations is determined from a pricing evaluation technique that uses information from market sources and integrates relative credit information, observed market movements, and sector news. Key inputs include benchmark yields, reported trades, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including sector, coupon, credit quality ratings, duration, credit enhancements, early redemption features and market research publications.

Mortgage and asset-backed securities: The fair value of mortgage and asset-backed securities is determined from a pricing evaluation technique that uses information from market sources and leveraging similar securities. Key inputs include benchmark yields, reported trades, underlying tranche cash flow data, collateral performance, plus new issue data, as well as broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including issuer, vintage, loan type, collateral attributes, prepayment speeds, default rates, recovery rates, cash flow stress testing, credit quality ratings and market research publications.

Municipal obligations: The fair value of municipal obligations is determined from a pricing evaluation technique that uses information from market makers, brokers-dealers, buy-side firms, and analysts along with general market information. Key inputs include benchmark yields, reported trades, issuer financial statements, material event notices and new issue data, as well as broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including type, coupon, credit quality ratings, duration, credit enhancements, geographic location and market research publications.

Foreign government, agency and provincial obligations: The fair value of foreign government, agency and provincial obligations is determined from a pricing evaluation technique that uses feeds from data sources in each respective country, including active market makers and inter-dealer brokers. Key inputs include benchmark yields, reported trades, broker-dealer quotes, two-sided markets, benchmark securities, bids, offers, local exchange prices, foreign exchange rates and reference data including coupon, credit quality ratings, duration and market research publications.

Level 3 valuations are generated from techniques that use assumptions not observable in the market. These unobservable assumptions reflect White Mountains’s assumptions that market participants would use in valuing the investment. Generally, certain securities may start out as Level 3 when they are originally issued but as observable inputs become available in the market, they may be reclassified to Level 2.

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 periodic and audited annual financial statements of hedge funds and private equity funds and discussing each fund’s pricing with the fund manager throughout the year. 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. The fair value of White Mountains’s investments in hedge funds and private equity funds has generally been determined using the fund manager’s NAV. In the event White Mountains believes that its estimate of NAV of a hedge fund or private equity fund differs from that reported by the fund manager due to illiquidity or other factors, White Mountains will adjust the reported NAV to more appropriately represent the fair value of its investment in the hedge fund or private equity fund. As of June 30, 2017 and December 31, 2016, White Mountains did not have any adjustments to the reported NAV of its investments in hedge funds and private equity funds.

Fair Value Measurements by Level

The following tables summarize White Mountains’s fair value measurements for investments as of June 30, 2017 and December 31, 2016 by level. The major security types were based on the legal form of the securities. White Mountains has disaggregated its fixed maturity investments based on the issuing entity type, which impacts credit quality, with debt securities issued by U.S. government entities carrying minimal credit risk, while the credit and other risks associated with other issuers, such as corporations, foreign governments, municipalities or entities issuing mortgage and asset-backed securities vary depending on the nature of the issuing entity type. White Mountains further disaggregates debt securities issued by corporations and common equity securities by industry sector because investors often reference commonly used benchmarks and their subsectors to monitor risk and performance. Accordingly, White Mountains has further disaggregated these asset classes into subclasses based on the similar sectors and industry classifications it uses to evaluate investment risk and performance against commonly used benchmarks, such as the Bloomberg Barclays U.S. Intermediate Aggregate and S&P 500 indices. The fair value measurements for derivative assets associated with White Mountains’s variable annuity business are presented in Note 7.

Mortgage and Asset-backed Securities

White Mountains purchases commercial mortgage-backed securities (“CMBS”) and residential mortgage-backed securities (“RMBS”) with the goal of maximizing risk adjusted returns in the context of a diversified portfolio. 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). White Mountains did not hold any RMBS categorized as sub-prime as of June 30, 2017.

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’s review of the characteristics of their underlying mortgage loan pools, such as credit scores and financial ratios. As of June 30, 2017, White Mountains did not hold any RMBS classified as non-prime. White Mountains’s non-agency RMBS portfolio is generally moderate-term and structurally senior. White Mountains does not own any collateralized loan obligations. White Mountains does not own any collateralized debt obligations, with the exception of $6.3 million of non-agency RMBS resecuritization tranches, each a senior tranche in its own right and each collateralized by a single earlier vintage Super Senior or Senior non-agency RMBS.

⁽²⁾At issuance, Senior, or in the case of resecuritization, the underlying securities, were rated “AAA” by Standard & Poor’s, “Aaa” by Moody’s or “AAA” by Fitch and were senior to non-“AAA” or non-“Aaa” bonds.

⁽³⁾At issuance, Subordinate were not rated “AAA” by Standard & Poor’s, “Aaa” by Moody’s or “AAA” by Fitch and were junior to “AAA” or “Aaa” bonds.

Non-agency Commercial Mortgage-backed Securities

White Mountains’s non-agency CMBS portfolio is generally moderate-term and structurally senior, with more than 30 points of subordination on average for both fixed rate and floating rate as of June 30, 2017. In general, subordination represents the percentage principal loss on the underlying collateral that would have to be absorbed by other securities lower in the capital structure before the more senior security incurs a loss. As of June 30, 2017, none of the underlying loans of the non-agency CMBS held by White Mountains were reported as non-performing.

The amount of fixed and floating rate securities and their tranche levels of White Mountains’s non-agency CMBS securities are as follows as of June 30, 2017:

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, and other long-term investments as of June 30, 2017 and 2016 consist of securities for which the estimated fair value has not been determined based upon quoted market price inputs for identical or similar securities.

The following tables summarize the changes in White Mountains’s fair value measurements by level for the three months ended June 30, 2017 and 2016:

Fair Value Measurements — transfers between levels - Six-month period ended June 30, 2017 and 2016

Transfers between levels are recorded using the fair value measurement as of the end of the quarterly period in which the event or change in circumstance giving rise to the transfer occurred.

During the first six months of 2017, one fixed maturity investments classified as Level 3 measurement in the prior period was transferred to Level 2 measurement because quoted market prices for similar securities that were considered reliable and could be validated against an alternative source were available at June 30, 2017. These measurements comprise “Transfers out” of Level 3 and “Transfers in” to Level 2 of $11.1 million for the period ended June 30, 2017.

During the first six months of 2016, there were no fixed maturity investments classified as Level 3 measurements in the prior period that were transferred to Level 2 measurements.

WTM Bank Facility

On August 14, 2013, White Mountains entered into a revolving credit facility with a syndicate of lenders administered by Wells Fargo Bank, N.A., which has a total commitment of $425.0 million and has a maturity date of August 14, 2018 (the “WTM Bank Facility”). As of June 30, 2017, the WTM Bank Facility was undrawn.

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.

MediaAlpha Bank Facility

On May 12, 2017, MediaAlpha entered into a secured credit facility (the “MediaAlpha Bank Facility”) with Western Alliance Bank, which has a total commitment of $20.0 million and has a maturity date of May 12, 2020. The MediaAlpha Bank Facility replaced MediaAlpha’s previous credit facility (the “Previous MediaAlpha Bank Facility”), which had a total commitment of $20.0 million. The MediaAlpha Bank Facility consists of a $5.0 million term loan facility, which has an outstanding balance of $4.6 million as of June 30, 2017, and a revolving loan facility for $15.0 million, which has an outstanding balance of $6.0 million as of June 30, 2017.

During both the three and six months ended June 30, 2017, MediaAlpha borrowed $11.0 million, $5.0 million on the term loan and $6.0 million on the revolving loan, under the MediaAlpha Bank Facility. During both the three and six months ended June 30, 2017, MediaAlpha repaid $0.4 million on the term loan under the MediaAlpha Bank Facility.

During the three and six months ended June 30, 2017, MediaAlpha repaid $11.7 million and $12.9 million under the Previous MediaAlpha Bank Facility.

The MediaAlpha Bank Facility carries a variable interest rate that is based on the Prime Rate, as published by the Wall Street Journal, plus a spread of 1.5% on the term loan facility and 0.25% on the revolving credit facility as of June 30, 2017.

The MediaAlpha Bank Facility is secured by intellectual property and the common stock of MediaAlpha’s subsidiaries, and contains various affirmative, negative and financial covenants that White Mountains considers to be customary for such borrowings, including a fixed charge coverage ratio and an asset coverage ratio.

Compliance

At June 30, 2017, White Mountains was in compliance with the covenants under all of its debt instruments.

Note 6. 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 Barbados, Gibraltar, Israel, Luxembourg, the Netherlands, the United Kingdom and the United States.

White Mountains’s effective tax rate related to pre-tax loss from continuing operations for the three months ended June 30, 2017 was different from the U.S. statutory rate of 35%, primarily due to a full valuation allowance on all U.S. operations, a tax benefit recorded at BAM and consolidated pre-tax loss being near break-even. For the three months ended June 30, 2017, BAM had other comprehensive income that was available to partially offset its loss from continuing operations. As a result, BAM recorded a tax benefit of $1.7 million in net income from continuing operations, with an offsetting tax expense in other comprehensive income.

White Mountains’s effective tax rate related to pre-tax income from continuing operations for the six months ended June 30, 2017 was different from the U.S. statutory rate of 35%, primarily due to a full valuation allowance on all U.S. operations, a tax benefit recorded at BAM and consolidated pre-tax income being near break-even. For the six months ended June 30, 2017, BAM had other comprehensive income that was available to partially offset its loss from continuing operations. As a result, BAM recorded a tax benefit of $2.3 million in net income from continuing operations, with an offsetting tax expense in other comprehensive income.

White Mountains’s income tax benefit related to pre-tax loss from continuing operations for the three and six months ended June 30, 2016, represented a net effective tax rate of 15.9% and 10.2%. The effective tax rate for the three and six months ended June 30, 2016 was lower than the U.S. statutory rate of 35%, primarily due to a full valuation allowance on all U.S. operations and losses generated in jurisdictions other than the United States.

In arriving at the effective tax rate for the three and six months ended June 30, 2017 and 2016, White Mountains forecasted all income and expense items including the change in unrealized investment gains (losses) and realized investment gains (losses) for the years ending December 31, 2017 and 2016.

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.

In the second quarter of 2016, White Mountains recorded an increase in deferred tax assets of $0.6 million and a corresponding increase in valuation allowance of $0.6 million related to the settlement of the IRS audit of Guilford Holdings, Inc. and subsidiaries for tax year 2012.

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 2013.

Note 7. Derivatives

Variable Annuity Reinsurance

White Mountains entered into agreements to reinsure death and living benefit guarantees associated with certain variable annuities in Japan. During the third quarter of 2015, the variable annuity contracts reinsured by WM Life Re began to mature and were fully runoff by June 30, 2016. The reinsurance agreement was commuted in December 2016.

The following table summarizes the pre-tax operating results of WM Life Re for the three and six months ended June 30, 2016.

⁽¹⁾Consists of over-the-counter instruments.

⁽²⁾Consists of interest rate swaps, total return swaps, foreign currency forward contracts, and bond forwards. Fair value measurement based upon bid/ask pricing quotes for similar instruments that are actively traded, where available. Swaps for which an active market does not exist have been priced using observable inputs including the swap curve and the underlying bond index.

⁽³⁾Consists of exchange traded equity index, foreign currency and interest rate futures. Fair value measurements based upon quoted prices for identical instruments that are actively traded.

All of White Mountains’s variable annuity reinsurance liabilities were classified as Level 3 measurements. The fair value of White Mountains’s variable annuity reinsurance liabilities were estimated using actuarial and capital market assumptions related to the projected discounted cash flows over the term of the reinsurance agreement. Actuarial assumptions regarding future policyholder behavior, including surrender and lapse rates, were generally unobservable inputs and significantly impacted the fair value estimates. Generally, the liabilities associated with these guarantees increased with declines in the equity markets, interest rates and currencies against the Japanese yen, as well as with increases in market volatilities. White Mountains used derivative instruments 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, were generally the same as those used to estimate the fair value of variable annuity liabilities.

Forward Contracts

White Mountains’s investment portfolio contains investment grade fixed maturity investments denominated in British Pound Sterling (GBP) and common equity securities denominated in Euro (EUR) and other European currencies. White Mountains has entered into foreign currency forward contracts to manage its foreign currency exposure related to these investments. The contracts do not meet the criteria to be accounted for as a hedge. White Mountains actively manages its net foreign currency exposure and adjusts its foreign currency positions within ranges established by senior management. Mismatches between currency driven movements in foreign denominated investments and foreign currency forward contracts may result in net foreign currency positions being outside pre-defined ranges and/or net foreign currency gains/(losses). At June 30, 2017, White Mountains held $302.0 million (GBP 150.0 million and EUR 104.0 million) total gross notional value of foreign currency forward contracts.

White Mountains’s foreign currency 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 June 30, 2017.

The net realized derivative loss recognized in net realized and unrealized investment gains (losses) for both the three and six months ended June 30, 2017 was $1.7 million. The net unrealized derivative loss recognized in net realized and unrealized investment gains (losses) for the three and six months ended June 30, 2017 was $8.5 million and $11.3 million. White Mountains’s forward contracts are subject to master netting agreements. As of June 30, 2017 and December 31, 2016, the gross liability amount offset under the master netting agreement and the net amount recognized in other long-term investments was $12.5 million and $1.2 million.

White Mountains does not hold or provide any collateral under its forward contracts. The following table summarizes the gross notional amount associated with the forward currency contracts:



	June 30, 2017
Millions	Notional Amount⁽¹⁾		Carrying Value			Standard & Poor's Rating ⁽²⁾
Barclays Bank PLC	$	187.3	$	(8.2	)	A-
JP Morgan	114.7		(4.3		)	A+
Total	$	302.0	$	(12.5	)

⁽¹⁾At June 30, 2017, WTM entered into a spot trade of $57.0 (EUR 50.0) in anticipation of settling a forward currency contract (gross notional: $52.7 (EUR 50.0) with JP Morgan set to expire on July 6, 2017.

⁽²⁾ Standard & Poor’s ratings as detailed above are: “A+” (Strong, which is the fifth highest of twenty-three creditworthiness ratings) and “A-” (Strong, which is the seventh highest of twenty-three creditworthiness ratings).

Note 8. Municipal Bond Guarantee Insurance

In 2012, HG Global was capitalized with $594.5 million from White Mountains and $14.5 million from non-controlling interests to fund BAM, a newly formed mutual municipal bond insurer. As of June 30, 2017, White Mountains owned 96.9% of HG Global’s preferred equity and 88.4% 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 and surplus of $469.7 million at June 30, 2017, 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 three and six months ended June 30, 2017, HG Global had pre-tax income of $6.7 million and $13.3 million, which included $4.7 million and $9.5 million of interest income on the BAM Surplus Notes. For the three and six months ended June 30, 2016, HG Global had pre-tax income of $5.9 million and $13.2 million, which included $4.4 million and $8.9 million of interest income on the BAM Surplus Notes.

For the three and six months ended June 30, 2017, White Mountains reported pre-tax losses of $11.5 million and $23.7 million on BAM that were recorded in net loss attributable to non-controlling interests, which included $4.7 million and $9.5 million of interest expense on the BAM Surplus Notes. For the three and six months ended June 30, 2016, White Mountains reported pre-tax losses of $9.0 million and $16.6 million on BAM that were recorded in net loss attributable to non-controlling interests, which included $4.4 million and $8.9 million of interest expense on the BAM Surplus Notes.

Effective January 1, 2014, HG Global and BAM agreed to change the interest rate on the BAM Surplus Notes for the five years ending December 31, 2018 from a fixed rate of 8.0% to a variable rate equal to the one-year U.S. treasury rate plus 300 basis points, set annually, which is 3.54% and 3.78% for 2016 and 2017. Prior to the end of 2018, BAM has the option to extend the variable rate period for an additional three years. At the end of the variable rate period, the interest rate will be fixed at the higher of the then current variable rate or 8.0%. No payment of interest or principal on the BAM Surplus Notes may be made without the approval of the New York State Department of Financial Services. BAM has stated its intention to seek regulatory approval to pay interest and principal on its surplus notes only to the extent that its remaining qualified statutory capital (“QSC”) exceeds $500 million and its remaining QSC and other capital resources continue to support its outstanding obligations, business plan and its AA stable rating from S&P.

During the three months ended June 30, 2017, in order to further support BAM’s long-term capital position and business prospects, HG Global agreed to contribute the $203.0 million Series A BAM Surplus Notes (“Series A Notes”) into the supplemental collateral trust (the “Supplemental Trust”) at HG Re, HG Global’s wholly owned reinsurance subsidiary. The Supplemental Trust already holds the $300.0 million Series B BAM Surplus Notes (“Series B Notes” and, collectively with the Series A Notes, the “BAM Surplus Notes”). Assets held in the Supplemental Trust serve to collateralize HG Re’s obligations to BAM under the first loss reinsurance treaty between BAM and HG Re. HG Global and BAM also agreed to change the payment terms of the Series B Notes, so that payments will reduce principal and accrued interest on a pro rata basis, consistent with the payment terms on the Series A Notes. The terms of the Series B Notes had previously stipulated that payments would first reduce interest owed, then reduce principal owed once all accrued interest had been paid. Such change is subject to approval by the New York Department of Financial Services, which is expected in the third quarter of 2017.

HG Global and BAM have also made certain changes to the ceding commission arrangements under the reinsurance treaty between HG Re and BAM. These changes will accelerate growth in BAM’s statutory capital but will not impact the net risk premium ceded from BAM to HG Re.

Under GAAP, if the terms of a debt instrument are amended, unless there is a greater than 10% change in the expected discounted future cash flows of such instrument, a change in the instrument’s carrying value is not permitted. White Mountains has determined that the impact of the changes to the terms of the BAM Surplus Notes on the expected discounted future cash flows is not greater than 10%.

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.

The following table provides a schedule of BAM’s insured obligations:



	June 30, 2017		December 31, 2016
Contracts outstanding	5,564		4,807
Remaining weighted average contract period outstanding (in years)	10.9		10.8

Note 9. Earnings Per Share

White Mountains calculates earnings per share using the two-class method, which allocates earnings between common and unvested restricted common shares. Both classes of shares participate equally in earnings on a per share basis. Basic earnings per share amounts are based on the weighted average number of common shares outstanding adjusted for unvested restricted common shares. Diluted earnings per share amounts are also impacted by the net effect of potentially dilutive common shares outstanding. The following table outlines the Company’s computation of earnings per share from continuing operations for the three and six months ended June 30, 2017 and 2016. See Note 15 — “Held for Sale and Discontinued Operations”.

⁽¹⁾ Restricted shares issued by White Mountains receive dividends, and therefore, are considered participating securities.

⁽²⁾Restricted shares outstanding vest either in equal annual installments or upon a stated date. See Note 13 — “Employee Share-Based Compensation Plans”.

⁽³⁾The diluted earnings per share denominator for the three and six months ended June 30, 2016 includes the impact of 120,000 common shares issuable upon exercise of the non-qualified options outstanding, which resulted in 10,863 and 6,194 incremental shares outstanding over the period.

Note 11. Segment Information

White Mountains has determined that its reportable segments are HG Global/BAM, MediaAlpha and Other Operations. As a result of the Sirius Group and Tranzact sales and the OneBeacon Transaction, the results of operations for Sirius Group and OneBeacon, previously reported in their own respective segments, and Tranzact, previously reported in the Other Operations segment, have been classified as discontinued operations and are now presented, net of related income taxes, as such in the statement of operations and comprehensive income. Beginning in the second quarter of 2017, MediaAlpha’s results have been presented as a separate segment within White Mountains’s consolidated financial statements. Prior year amounts have been reclassified to conform to the current period’s presentation. See Note 15 — “Held for Sale and Discontinued Operations”.

White Mountains has made its segment determination based on consideration of the following criteria: (i) the nature of the business activities of each of the Company’s subsidiaries and affiliates; (ii) the manner in which the Company’s subsidiaries and affiliates are organized; (iii) the existence of primary managers responsible for specific subsidiaries and affiliates; and (iv) the organization of information provided to the chief operating decision makers and the Board of Directors.

Significant intercompany transactions among White Mountains’s segments have been eliminated herein. Financial information for White Mountains’s segments follows:

Note 12. Investment in Symetra

White Mountains’s investment in Symetra represented an investment in which White Mountains had a significant voting and economic interest but did not control the entity.

In August 2015, Symetra announced it had entered into a definitive merger agreement with Sumitomo Life pursuant to which Sumitomo Life would acquire all of the outstanding shares of Symetra. Following the announcement and Symetra shareholders’ November 5, 2015 meeting to approve the transaction, White Mountains relinquished its representation on Symetra’s board of directors. As a result, White Mountains changed its accounting for Symetra common shares from the equity method to fair value as of December 31, 2015. During the fourth quarter of 2015, White Mountains recognized $258.8 million ($241.1 million after tax) of unrealized investment gains through net income, representing the difference between the carrying value of Symetra common shares under the equity method at the date of change and fair value at December 31, 2015. White Mountains also received a special dividend of $0.50 per share as part of the transaction that was paid in the third quarter of 2015. On February 1, 2016, Symetra closed its definitive merger agreement with Sumitomo Life and White Mountains received proceeds of $658.0 million, or $32.00 per common share. White Mountains recognized $4.7 million in pre-tax net investment gains associated with Symetra in the first quarter of 2016.

Note 13. Employee Share-Based Incentive Compensation Plans

White Mountains’s 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 of White Mountains. White Mountains’s share-based compensation incentive awards consist of performance shares, restricted shares and stock options.

Share-Based Compensation Based on White Mountains Common Shares

WTM Performance Shares

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 approved for payment. The following table summarizes performance share activity for the three and six months ended June 30, 2017 and 2016 for performance shares granted under the WTM Incentive Plan:

⁽¹⁾WTM performance share payments in 2017 for the 2014-2016 performance cycle, which were paid in March 2017, ranged from 34% to 76% of target. WTM performance share payments in 2016 for the 2013-2015 performance cycle ranged from 140% to 142% of target.

⁽²⁾Amounts include changes in assumed forfeitures, as required under GAAP.

⁽³⁾Outstanding performance share awards as of June 30, 2017 and 2016 exclude 2,195 and 7,315 performance share awards granted to employees of Sirius Group.

For performance shares earned in the 2014-2016 performance cycle, all performance shares earned were settled in cash. For the performance shares earned in the 2013-2015 performance cycle, the Company issued 5,000 common shares and settled the remainder in cash. If all the outstanding WTM performance shares had vested on June 30, 2017, the total additional compensation cost to be recognized would have been $32.3 million, based on accrual factors (common share price and payout assumptions) at June 30, 2017.

Stock Options

Non-Qualified Options

As January 20, 2017, the 125,000 Non-Qualified options issued to the Company’s former Chairman and CEO had been exercised.

The Non-Qualified Options were fully amortized as of 2011.

Note 14. Fair Value of Financial Instruments

White Mountains accounts for its financial instruments at fair value with the exception of the WTM Bank Facility, which was undrawn at June 30, 2017 and December 31, 2016, the MediaAlpha Bank Facility and the Previous MediaAlpha Bank Facility, which is recorded as debt at face value less unamortized original issue discount.

The fair value estimate for the MediaAlpha Bank Facility and the Previous MediaAlpha Bank Facility has been determined based on a discounted cash flows approach and is considered to be a Level 3 measurement.

Note 15. Held for Sale and Discontinued Operations

OneBeacon

On May 2, 2017, OneBeacon entered into a definitive agreement to be acquired by Intact Financial Corporation in an all-cash transaction for $18.10 per share, or roughly 1.65x tangible book value.

On July 18, 2017, White Mountains voted its shares of OneBeacon Ltd. in favor of the OneBeacon Transaction. White Mountains expects to receive gross proceeds of $1.3 billion from the OneBeacon Transaction, which is expected to close in the third or fourth quarter of 2017 and is subject to regulatory approval and other customary closing conditions. The results of OneBeacon have been presented as discontinued operations in the statement of operations and comprehensive income for all periods and OneBeacon’s assets and liabilities have been presented as held for sale as of June 30, 2017 and December 31, 2016. See Note 2 — “Significant Transactions”.

During 2016, White Mountains recorded a $51.9 million gain from the sale of Tranzact in discontinued operations, which included a $30.2 million tax expense for the reversal of a tax valuation allowance that is offset by a tax benefit recorded in continuing operations.

In the first quarter of 2017, White Mountains recorded a $1.0 million reduction to the gain from sale of Tranzact in discontinued operations as a result of 2016 tax payments.

During 2016, White Mountains recognized a $21.4 million tax benefit in continuing operations related to the reversal of a valuation allowance that resulted from the gain on the sale of Tranzact recognized within discontinued operations.

During 2016, White Mountains recorded $363.2 million of gain from sale of Sirius Group in discontinued operations in the statement of operations and $113.3 million in other comprehensive income from discontinued operations.

Earnings Per Share

White Mountains calculates earnings per share using the two-class method, which allocates earnings between common and unvested restricted common shares. Both classes of shares participate equally in earnings on a per share basis. Basic earnings per share amounts are based on the weighted average number of common shares outstanding adjusted for unvested restricted common shares. Diluted earnings per share amounts are also impacted by net effect of potentially dilutive common shares outstanding. The following table outlines the Company’s computation of earnings per share for discontinued operations for the three and six months ended June 30, 2017 and 2016:



	Three Months Ended						Six Months Ended
	June 30,						June 30,

Diluted earnings per share (in dollars):	$	.61		$	75.11		$	7.47		$	80.96

⁽¹⁾Restricted shares issued by White Mountains contain dividend participation features, and therefore, are considered participating securities.

⁽²⁾Net earnings attributable to White Mountains’s common shareholders, net of restricted share amounts, is equal to undistributed earnings for the three and six months ended June 30, 2017 and 2016.

⁽³⁾ Restricted common shares outstanding vest either in equal annual installments or upon a stated date. See Note 13 — “Employee Share-Based Compensation Plans”.

⁽⁴⁾The diluted earnings per share denominator for the three and six months ended June 30, 2016 includes the impact of 120,000 common shares issuable upon exercise of the non-qualified options outstanding, which resulted in 10,863 and 6,194 incremental shares outstanding over the period.

Fair Value of Financial Instruments

The OBH Senior Notes are recorded as debt at face value less unamortized original issue discount. The following table summarizes the fair value and carrying value of this financial instrument as of June 30, 2017 and December 31, 2016:



	June 30, 2017				December 31, 2016
Millions	Fair Value		Carrying Value		Fair Value		Carrying Value
OBH Senior Notes	$	282.4	$	273.3	$	274.2	$	273.2

The fair value estimate for the OBH Senior Notes has been determined using quoted market prices. The OBH Senior Notes are considered a Level 2 measurement.

OneBeacon Surplus Notes

In the fourth quarter of 2014, in conjunction with OneBeacon’s sale of its runoff business to an affiliate of Armour Group Holdings Limited (the “OneBeacon Runoff Transaction”), OneBeacon provided financing in the form of surplus notes (the “OneBeacon Surplus Notes”) with a par value of $101.0 million which had a fair value of $70.5 million and $71.9 million as of June 30, 2017 and December 31, 2016. The OneBeacon Surplus Notes, issued by one of the transferred entities, Bedivere Insurance Company (the “Issuer”) were in the form of both seller priority and pari passu notes.

Subsequent to closing, the OneBeacon Surplus Notes are included in OneBeacon’s investment portfolio, classified within other long-term investments. The internal valuation model used to estimate the fair value of the OneBeacon Surplus Notes is based on discounted expected cash flows using information as of the measurement date.

Below is a table illustrating the valuation adjustments taken to arrive at estimated fair value of the OneBeacon Surplus Notes as of June 30, 2017 and December 31, 2016:



	Type of Surplus Note						Total as of June 30, 2017			Total as of December 31, 2016
Millions	Seller Priority			Pari Passu			Total as of June 30, 2017			Total as of December 31, 2016

Fair value⁽⁴⁾	$	48.9		$	21.6		$	70.5		$	71.9

⁽¹⁾

Represents the value of the surplus notes, at current market yields on comparable publicly traded debt, and assuming issuer is allowed to make principal and interest payments when its financial capacity is available, as measured by statutory capital in excess of a 250% RBC score under the National Association of Insurance Commissioners’ risk-based capital standards for property and casualty companies. The favorable year-to-date change in impact is due principally to the narrowing of non-investment grade credit spreads as well as the time value of money benefit from moving three months closer to modeled cash receipts.

⁽²⁾

Represents anticipated delay in securing regulatory approvals of interest and principal payments to reflect graduated changes in Issuer's statutory surplus. The monetary impact of the anticipated delay is measured based on credit spreads of public securities with roughly equivalent percentages of discounted payments missed. The favorable year-to-date change in impact is driven primarily by the narrowing of non-investment grade credit spreads, which causes negative valuation impact from the anticipated delay in securing regulatory approval to be lower.

⁽³⁾ Represents impact of liquidity spread to account for OneBeacon's sole ownership of the notes, lack of a trading market, and unique nature of the ongoing regulatory approval process. The unfavorable year-to-date change in impact is due largely to an increase in the assumed liquidity spread to 400 basis points at June 30, 2017 from 250 basis points at December 31, 2016.

⁽⁴⁾ The decrease in the fair value of the surplus notes during the six months ended June 30, 2017 was driven primarily by an increase in the assumed liquidity spread, partially offset by the narrowing of non-investment grade credit spreads as well as the time value of money benefit generated by moving three months closer to modeled cash receipts.

Note 16. Contingencies

Legal Contingencies

White Mountains is 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 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 if there is a reasonable possibility that a loss may have been incurred.

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’s financial condition, results of operations or cash flows.

The following summarizes White Mountains’s significant legal contingencies, ongoing non-claims related litigation or arbitration as of June 30, 2017:

Litigation Related to the OneBeacon Transaction

On June 2, 2017, Stephen Bushansky, a purported OneBeacon shareholder, filed a class action complaint against OneBeacon and each of OneBeacon’s directors in the U.S. District Court for the District of Minnesota (the “Minnesota Court”), purportedly on behalf of OneBeacon’s public shareholders. Thereafter, three additional lawsuits were filed in the Minnesota Court by additional purported shareholders, Darrin Dickers, Raymond Martino and Robert Berg (collectively with Bushansky, the “Plaintiffs”). The complaints in each pending class action allege that OneBeacon’s preliminary proxy statement filed with the U.S. Securities and Exchange Commission (“SEC”) omitted or misrepresented certain material information, allegedly in violation of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 14a-9 and sought to enjoin OneBeacon and Intact Financial Corporation from closing the OneBeacon Transaction, or if the transaction closes, to award Plaintiffs damages and costs.

On June 26, 2017, Plaintiffs jointly filed a motion for preliminary injunction to enjoin the shareholder vote on the OneBeacon Transaction, but withdrew their motion on July 7, 2017. OneBeacon’s shareholders approved the OneBeacon Transaction on July 18, 2017 at a special general meeting of shareholders. Plaintiffs have not dismissed their cases and OneBeacon’s responsive pleadings are due August 14, 2017. OneBeacon believes the cases lack merit and continues to vigorously defend this litigation.

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, OneBeacon-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”). The Bankruptcy Court granted Plaintiffs permission to commence these LBO-related actions, and in 2011, the Judicial Panel on Multidistrict Litigation granted a motion to consolidate the actions for pretrial matters and transferred all such proceedings to the U.S. District Court for the Southern District of New York (the “SDNY”).

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 and OneBeacon-sponsored benefit plans received approximately $32.0 million for Tribune common stock tendered in connection with the LBO.

The Court granted an omnibus motion to dismiss the Noteholder Actions in September 2013 and Plaintiffs’ appealed. On March 29, 2016, a three judge panel of the U.S Second Circuit Court of Appeals affirmed the dismissal of the Noteholder Actions. On July 22, 2016, the Plaintiff’s petition to the Second Circuit for reconsideration or for a rehearing en banc was denied in full. On September 9, 2016 the Plaintiffs filed for a writ of certiorari, seeking review in the U. S. Supreme Court.

In addition, OneBeacon and OneBeacon-sponsored benefit plans 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 (the “Committee”), 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”). Tribune emerged from bankruptcy in 2012, and a litigation trustee replaced the Committee as plaintiff in the Committee Action. This matter was consolidated for pretrial matters with the Noteholder Actions in the SDNY and was stayed pending the motion to dismiss in the Noteholder Actions. An omnibus motion to dismiss the shareholder defendants in the Committee Action was filed in May 2014 and the motion was granted on January 6, 2017. The plaintiff has requested permission to move the SDNY to certify the decision as a final judgment capable of immediate appeal. No amount has been accrued in connection with this matter as of June 30, 2017, as the amount of loss, if any, cannot be reasonably estimated.

Note 17. Subsequent Event

In July 2017, White Mountains repurchased 235,000 common shares for $199.8 million.


Item 2.	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’s actual results could be materially different from and worse than its expectations. See “FORWARD-LOOKING STATEMENTS” for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

The following discussion also include six non-GAAP financial measures (i) adjusted book value per share, (ii) percentage change in adjusted book value per share including the estimated gain from the OneBeacon Transaction and excluding the new adjustments from HG Global/BAM, (iii) adjusted capital, (iv) return on common equity securities and other long-term investments including high-yield fixed maturity investments, (v) return on fixed maturity investments excluding high-yield fixed maturity investments and (vi) earnings before interest, taxes, depreciation and amortization ("EBITDA") that have been reconciled to their most comparable GAAP financial measures on page 67. White Mountains believes these measures to be useful in evaluating White Mountains’s financial performance and condition.

RESULTS OF OPERATIONS FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2017 AND 2016

Overview

White Mountains ended the second quarter of 2017 with book value per share of $798 and adjusted book value per share of $780. Book value per share increased 1% for both the second quarter and first six months of 2017 and adjusted book value per share decreased 2% for both the second quarter and first six months of 2017, including dividends.

During the second quarter of 2017, White Mountains changed its calculation of adjusted book value per share to (i) include a discount for the time value of money on the BAM Surplus Notes and (ii) add back the unearned premium reserve, net of deferred acquisition costs, at HG Global. These changes decreased adjusted book value per share by $23.

On May 2, 2017, OneBeacon entered into a definitive agreement to be acquired by Intact Financial Corporation in an all-cash transaction for $18.10 per share, or roughly 1.65x tangible book value (the “OneBeacon Transaction”). White Mountains expects to receive gross proceeds of $1.3 billion from the OneBeacon Transaction, which is expected to close in the third or fourth quarter of 2017 and is subject to regulatory approval and other customary closing conditions. As the OneBeacon Transaction was set at a fixed price, the results of OneBeacon do not impact White Mountains’s adjusted book value per share including the estimated gain from the transaction between signing and closing. Including the estimated net gain of $116 per share from the OneBeacon Transaction, book value per share would be approximately $914 and adjusted book value per share would be approximately $896 as of June 30, 2017. Excluding the changes for HG Global/BAM noted above, growth in book value per share including the estimated net gain from the OneBeacon Transaction was 1.6% and growth in adjusted book value per share including the estimated gain from the OneBeacon Transaction was 1.4% in the second quarter of 2017, driven primarily by good investment returns.

The estimated net gain per share from the OneBeacon Transaction increased by $9 to $116 per share in the second quarter of 2017. Approximately $3 of the increase was attributable to the impact of OneBeacon’s regular dividend paid during the second quarter of 2017. The remainder of the increase was due to revised estimation and recording of compensation costs in connection with the transaction in the second quarter of 2017. Beginning in the second quarter of 2017, OneBeacon’s results have been presented as discontinued operations. As a result, MediaAlpha’s results have been presented as a separate segment within White Mountains’s consolidated financial statements.

BAM’s gross written premiums and member surplus contributions totaled $20 million and $48 million in the second quarter and first six months of 2017, compared to $19 million and $32 million in the second quarter and first six months of 2016. Total pricing (i.e., premiums and member surplus contributions weighted by the par value of bonds insured) was 79 and 98 basis points in the second quarter and first six months of 2017, up from 58 and 60 basis points in the second quarter and first six months of 2016. BAM insured municipal bonds with par value of $2.7 billion and $5.1 billion in the second quarter and first six months of 2017, compared to $3.3 billion and $5.5 billion in the second quarter and first six months of 2016. The decrease in par value insured by BAM in the second quarter of 2017, as compared to last year, was primarily due to the rating uncertainty during S&P’s review, which commenced on June 6, 2017. On June 26, 2017, S&P affirmed BAM’s AA rating with stable outlook. BAM’s total claims paying resources increased $32 million to $676 million in the first six months of 2017, compared to an increase of $16 million to $617 million in the first six months of 2016.

MediaAlpha’s pre-tax loss was $2 million and $3 million in the second quarter and first six months of 2017, compared to $1 million in both the second quarter and first six months of 2016. MediaAlpha’s earnings before income taxes, depreciation and amortization (“EBITDA”) of $1 million and $3 million in the second quarter and first six months of 2017, compared to $2 million and $4 million in the second quarter and first six months of 2016. The increase in pre-tax loss and decrease in EBITDA was primarily driven by increased operating expenses of $1 million for both the second quarter and first six months of 2017, as MediaAlpha continued to invest in growth in new verticals.

The GAAP total return on invested assets, including continuing operations and discontinued operations, was 1.4% and 2.9% for the second quarter and first six months of 2017 compared to 0.8% and 2.4% for the second quarter and first six months of 2016.

The fixed income portfolio, excluding high-yield fixed maturity investments, returned 1.0% for the second quarter of 2017, in line with the longer duration Bloomberg Barclays U.S. Intermediate Aggregate Index return of 0.9%. Excluding high-yield fixed maturity investments, fixed income duration remained relatively constant in the quarter at approximately 3.0 years. The portfolio of common equity securities and other long-term investments, including high-yield fixed maturity investments, returned 2.6% for the second quarter of 2017, underperforming the S&P 500 Index return of 3.1% due to unfavorable other long-term investments results, primarily attributable to losses from currency hedges, as well as the impact of unconsolidated private capital investments and the OneBeacon Surplus Notes, which were both relatively flat during the quarter. The underperformance was partially offset by common equity security returns of 4.2% for the quarter, as White Mountains’s third party managers each outperformed their respective benchmarks. The losses on the currency hedges were offset by currency gains from non-USD denominated fixed maturity investments and non-USD denominated common equity securities, with currency hedges having a negligible impact on overall total returns for the second quarter of 2017.

The fixed income portfolio, excluding high-yield fixed maturity investments, returned 1.8% for the first six months of 2017, ahead of the longer duration Bloomberg Barclays U.S. Intermediate Aggregate Index return of 1.6%. The portfolio of common equity securities and other long-term investments, including high-yield fixed maturity investments, returned 6.0% for the first six months of 2017, underperforming the S&P 500 Index return of 9.3%, driven by asset allocation, as high-yield fixed maturity investments failed to keep pace with the S&P 500 Index, and unfavorable other long-term investments results, primarily attributable to losses from currency hedges, the impact of unconsolidated private capital investments and unfavorable mark-to-market adjustments to the OneBeacon Surplus Notes. The underperformance was partially offset by common equity security returns of 9.6% for the first six months of 2017, as White Mountains’s third party managers each outperformed their respective benchmarks. The losses on the currency hedges were offset by currency gains from non-USD denominated fixed maturity investments and non-USD denominated common equity securities, with currency hedges having a negligible impact on overall total returns for the first six months of 2017.

Consolidated Results - Three Months Ended June 30, 2017 versus Three Months Ended June 30, 2016

White Mountains’s total revenues increased 74% to $85 million in the second quarter of 2017, driven by higher investment returns. Net realized and unrealized investment gains increased to $34 million in the second quarter of 2017, compared to $3 million in the second quarter of 2016. Net investment income was $15 million in the second quarter of 2017 compared to $6 million in the second quarter of 2016. See Summary of Investment Results on page 57.

White Mountains’s total expenses increased 15% to $86 million in the second quarter of 2017, primarily due to general and administrative expenses, which increased 30% to $55 million in the second quarter of 2017. The increase in general and administrative expenses was driven by higher incentive compensation costs, primarily related to the OneBeacon Transaction.

White Mountains’s effective tax rate related to pre-tax loss from continuing operations for the second quarter of 2017 was different from the U.S. statutory rate of 35%, primarily due to a full valuation allowance on all U.S. operations, a tax benefit recorded at BAM and consolidated pre-tax loss being near break-even. For the second quarter of 2017, BAM had other comprehensive income that was available to partially offset its loss from continuing operations. As a result, BAM recorded a tax benefit of $2 million in net income from continuing operations, with an offsetting tax expense in other comprehensive income. White Mountains’s income tax benefit related to pre-tax loss from continuing operations for the second quarter of 2016 represented a net effective tax rate of 15.9%, which was lower than the U.S. statutory rate of 35%, primarily due to a full valuation allowance on all U.S. operations and losses generated in jurisdictions other than the United States.

Consolidated Results - Six Months Ended June 30, 2017 versus Six Months Ended June 30, 2016

White Mountains’s total revenues increased 66% to $179 million in the first six months of 2017, driven by higher investment returns. Net realized and unrealized investment gains increased to $70 million in the first six months of 2017, compared to $16 million in the first six months of 2016. Net investment income was $28 million in the first six months of 2017 compared to $9 million in the first six months of 2016. See Summary of Investment Results on page 57.

White Mountains’s total expenses increased 9% to $178 million in the first six months of 2017, primarily due to general and administrative expenses, which increased 20% to $113 million in the first six months of 2017. The increase in general and administrative expenses was driven by additional compensation expenses related to former company executives and higher incentive compensation costs in connection with the OneBeacon Transaction.

White Mountains’s income tax benefit related to pre-tax loss from continuing operations for the first six months of 2016 represented a net effective tax rate of 10.2%, which was lower than the U.S. statutory rate of 35%, primarily due to a full valuation allowance on all U.S. operations and losses generated in jurisdictions other than the United States.

I. Summary of Operations By Segment

White Mountains conducts its operations through three segments: (1) HG Global/BAM, (2) MediaAlpha and (3) Other Operations. While investment results are included in HG Global/BAM and Other Operations, White Mountains manages the majority of its investments through its wholly-owned subsidiary, WM Advisors. Accordingly, a discussion of White Mountains’s consolidated investment operations is included after the discussion of operations by segment. White Mountains’s segment information is presented in Note 11 — “Segment Information” to the Consolidated Financial Statements.

As a result of the Sirius Group and Tranzact sales and the OneBeacon Transaction, the results of operations for Sirius Group, Tranzact and OneBeacon have been classified as discontinued operations and are now presented separately, net of related income taxes, in the statement of comprehensive income. Prior year amounts have been reclassified to conform to the current period’s presentation. See Note 15 — “Held for Sale and Discontinued Operations”.

HG Global/BAM

BAM is a mutual insurance company whose affairs are managed on a statutory accounting basis, and it does not report stand-alone GAAP financial results. BAM is owned by its members, the municipalities that purchase BAM’s insurance for their debt issuances. BAM charges an insurance premium on each municipal bond insurance policy it insures. A portion of the premium is a member surplus contribution, which is contributed to BAM’s qualified statutory capital and conveys to the issuer certain interests in BAM, including the right to receive dividends in the future, subject to regulatory approval. The remainder is a risk premium, which is recorded as gross written premiums.

In order to further support BAM’s long-term capital position and business prospects, HG Global agreed to contribute the $203 million Series A BAM Surplus Notes (“Series A Notes”) into the supplemental collateral trust (the “Supplemental Trust”) at HG Re, HG Global’s wholly owned reinsurance subsidiary. The Supplemental Trust already holds the $300 million Series B BAM Surplus Notes (“Series B Notes” and, collectively with the Series A Notes, the “BAM Surplus Notes”). Assets held in the Supplemental Trust serve to collateralize HG Re’s obligations to BAM under the first loss reinsurance treaty between BAM and HG Re. HG Global and BAM also agreed to change the payment terms of the Series B Notes, so that payments will reduce principal and accrued interest on a pro rata basis, consistent with the payment terms on the Series A Notes. The terms of the Series B Notes had previously stipulated that payments would first reduce interest owed, then reduce principal owed once all accrued interest had been paid. Such change is subject to approval by the New York Department of Financial Services, which is expected in the third quarter of 2017.

On June 6, 2017, S&P placed BAM on credit watch negative and initiated a detailed review of BAM’s financial strength rating. On June 26, 2017, S&P concluded its review and affirmed BAM’s “AA/Stable” financial strength rating.

The following table presents the components of pre-tax income included in White Mountains’s HG Global/BAM segment related to the consolidation of HG Global, which includes HG Re and its other wholly-owned subsidiaries, and BAM for the three and six months ended June 30, 2017 and 2016:

During the second quarter of 2017, White Mountains changed its calculation of adjusted book value per share to (i) include a discount for the time value of money on the BAM Surplus Notes and (ii) add back the unearned premium reserve, net of deferred acquisition costs, at HG Global. At June 30, 2017, these adjustments reduced White Mountains’s adjusted book value per share by approximately $23. See “NON-GAAP FINANCIAL MEASURES” on page 67.

HG Global/BAM Results—Three Months Ended June 30, 2017 versus Three Months Ended June 30, 2016

In the second quarter of 2017, BAM insured $2.7 billion of municipal bonds, $2.6 billion of which were in the primary market, compared to $3.3 billion of municipal bonds, $3.1 billion of which were in the primary market, insured in the second quarter of 2016. The decrease in par value insured by BAM in the second quarter of 2017 was primarily due to the rating uncertainty during S&P’s review. Gross written premiums and member surplus contributions totaled $20 million for the second quarter of 2017, compared to $19 million for the second quarter of 2016. Total pricing (i.e., gross written premiums and member surplus contributions weighted by the par value of bonds insured) was 79 basis points in the second quarter of 2017, up from 58 basis points in the second quarter of 2016.

HG Global reported GAAP pre-tax income of $7 million in the second quarter of 2017, compared to $6 million the second quarter of 2016. Results for the second quarter of 2017 and 2016 were driven by $5 million and $4 million of interest income on the BAM Surplus Notes.

As a mutual insurance company that is owned by its members, BAM’s results do not affect White Mountains’s book value per share and adjusted book value per share. However, White Mountains consolidates BAM’s results in its GAAP financial statements and its results are attributed to non-controlling interests. White Mountains reported $12 million of GAAP pre-tax loss from BAM in the second quarter of 2017, compared to $9 million in the second quarter of 2016. The increase was primarily due to lower investment results. Results for the second quarter of 2017 include $5 million of interest expense on the BAM Surplus Notes and $10 million of operating expenses, compared to $4 million interest expense and $10 million of operating expenses in the second quarter of 2016.

HG Global/BAM Results—Six Months Ended June 30, 2017 versus Six Months Ended June 30, 2016

In the first six months of 2017, BAM insured $5.1 billion of municipal bonds, $4.6 billion of which were in the primary market, compared to $5.5 billion of municipal bonds, $5.2 billion of which were in the primary market, insured in the first six months of 2016. The decrease in par value insured by BAM in the first six months of 2017 was primarily due to the rating uncertainty during S&P’s review. Gross written premiums and member surplus contributions totaled $48 million for the first six months of 2017, compared to $32 million for the first six months of 2016. Total pricing was 98 basis points, up from 60 basis points in the first six months of 2016.

HG Global reported GAAP pre-tax income of $13 million in the first six months of 2017, compared to $13 million in the first six months of 2016. Results for the first six months of 2017 were driven by $10 million of interest income on the BAM Surplus Notes, compared to $9 million of interest income in the first six months of 2016. The increase in the interest income is due to the increase in the variable rate of the BAM Surplus Notes which is set annually. The variable rate is 3.78% for 2017 and was 3.54% for 2016.

White Mountains reported $24 million of GAAP pre-tax loss from BAM in the first six months of 2017, compared to $17 million in the first six months of 2016. Results for the first six months of 2017 were driven by $10 million of interest expense on the BAM Surplus Notes and $20 million of operating expenses, compared to $9 million interest expense and $19 million of operating expenses in the first six months of 2016. The increase in pre-tax loss in the first six months of 2017 was primarily due to higher realized and unrealized investment losses.

Claims Paying Resources

BAM’s “claims paying resources” represent the capital and other financial resources BAM has available to pay claims and, as such, is a key indication of BAM’s financial strength. BAM’s claims-paying resources include BAM’s qualified statutory capital, including member surplus contributions and contingency reserves, net unearned premiums, present value of future installment premiums and the first loss reinsurance protection provided by HG Re, which is collateralized and held in trusts. BAM expects member surplus contributions and HG Re’s reinsurance protection to be the primary drivers of continued growth of its claims-paying resources.

As of June 30, 2017, BAM’s claims paying resources increased 5% to $676 million from $644 million as of December 31, 2016. The increase was primarily driven by a $20 million increase in the HG Re collateral trusts and $17 million of member surplus contributions, partially offset by BAM’s statutory net loss for the six months ended June 30, 2017 of $12 million.

The following table presents BAM’s total claims paying resources as of June 30, 2017 and December 31, 2016:



Millions	June 30, 2017		December 31, 2016
Policyholders’ surplus	$	431.5	$	431.5

Present value of future installment premiums	6.4		3.3
Collateral trusts	182.6		163.0
Claims paying resources	$	675.9	$	643.7

As of June 30, 2016, BAM’s claims paying resources increased 3% to $617 million from $601 million as of December 31, 2015. The increase was primarily driven by $17 million of member surplus contributions and $12 million increase in the HG Re collateral trusts, partially offset by BAM’s statutory net loss for the six months ended of $16 million.

The following table presents BAM’s total claims paying resources as of June 30, 2016 and December 31, 2015:

Revenues increased $4 million in MediaAlpha’s non-P&C verticals, partially offset by a $1 million decrease in MediaAlpha’s P&C vertical, which includes auto, motorcycle, and home insurance. The decrease in MediaAlpha’s P&C vertical was driven primarily by reduced marketing budgets from auto carriers.

MediaAlpha’s cost of sales is comprised primarily of revenue share based payments to partners. Cost of sales were $26 million in the second quarter of 2017, compared to $23 million in the second quarter of 2016. The increase was driven by revenue growth. Cost of sales increased $4 million in MediaAlpha’s non-P&C verticals, partially offset by a $1 million decrease in MediaAlpha’s P&C vertical.

Other Operations Results—Three Months Ended June 30, 2017 versus Three Months Ended June 30, 2016

White Mountains’s Other Operations segment reported pre-tax income of $6 million in the second quarter of 2017, compared to pre-tax loss of $21 million in the second quarter of 2016. The improved results primarily were driven by higher investment returns, partially offset by higher compensation costs. White Mountains’s Other Operations segment reported $33 million of net realized and unrealized investment gains in the second quarter of 2017 compared to break-even results in the second quarter of 2016. White Mountains’s Other Operations segment reported $12 million of net investment income in the second quarter of 2017 compared to net investment income of $4 million in the second quarter of 2016. See Summary of Investment Results on page 57. White Mountains’s Other Operations segment other revenues were $1 million in the second quarter of 2017, compared to $7 million in the second quarter of 2016. The decrease was primarily driven by third party fees at WM Advisors. White Mountains’s Other Operations segment general and administrative expenses were $41 million in the second quarter of 2017, compared to $30 million in the second quarter of 2016. The increase was driven by higher incentive compensation costs, primarily in connection with the the OneBeacon Transaction and additional compensation expense related to the departure of the Company’s former CFO.

Other Operations Results—Six Months Ended June 30, 2017 versus Six Months Ended June 30, 2016

White Mountains’s Other Operations segment reported pre-tax income of $14 million in the first six months of 2017, compared to pre-tax loss of $50 million in the first six months of 2016. White Mountains’s Other Operations segment reported net realized and unrealized investment gains of $68 million in the first six months of 2017 compared to net realized and unrealized investment gains of $6 million in the first six months of 2016. White Mountains’s Other Operations segment reported $22 million of net investment income in the first six months of 2017 compared to net investment income of $4 million in the first six months of 2016. See Summary of Investment Results on page 57. White Mountains’s Other Operations segment other revenues were $4 million in the first six months of 2017, compared to $13 million in the first six months of 2016. The decrease was primarily driven by third party fees at WM Advisors. White Mountains’s Other Operations segment general and administrative expenses were $85 million in the first six months of 2017, compared to $69 million in first six months of 2016. The increase was primarily driven by higher incentive compensation costs, primarily in connection with the OneBeacon Transaction and additional compensation expense related to the departures of the Company’s former Chairman and CEO and former CFO.

Discontinued Operations

OneBeacon

OneBeacon’s reported book value per share increased 0.1% for the second quarter and 2.9% for the first six months of 2017, including dividends. OneBeacon’s combined ratio was 107% and 101% for the second quarter and first six months of 2017, compared to 103% and 99% for the second quarter and first six months of 2016. The increases in the combined ratios were driven largely by increased losses in the Financial Institutions, Healthcare, and Program businesses. Catastrophe losses added four points and two points to the combined ratios for the second quarter and first six months of 2017, compared to two points and one point for the second quarter and first six months of 2016. Texas hail storms primarily affecting Government Risks were the main driver of catastrophe losses in the quarter. Net unfavorable loss reserve development, primarily in the Program business, added three points and one point for the second quarter and first six months of 2017, compared to six points and three points in the second quarter and first six months of 2016, primarily in Healthcare. Transaction related incentive compensation expenses added two points and one point for the second quarter and first six months of 2017.

Net written premiums were $290 million and $547 million in the second quarter and first six months of 2017, compared to $261 million and $541 million in the second quarter and first six months of 2016. See Note 15 — “Held for Sale and Discontinued Operations”.

Tranzact

On July 21, 2016, White Mountains completed the sale of Tranzact to an affiliate of Clayton, Dubilier & Rice, LLC.

Tranzact’s results inured to White Mountains until the closing date of the transaction. Net loss from discontinued operations related to Tranzact was $3 million and $1 million for the second quarter and first six months of 2016. See Note 15 — “Held for Sale and Discontinued Operations”.

Sirius Group

On April 18, 2016, White Mountains completed the sale of Sirius Group to CMI. Sirius Group’s results inured to White

Mountains until the closing date of the transaction. For the second quarter stub period up until the closing date of the transaction, Sirius Group reported a comprehensive loss of $9 million, primarily due to $17 million of recorded losses from the Ecuador earthquake that occurred on April 16, 2016. For the first quarter of 2016, Sirius Group reported comprehensive income of $36 million, reflecting a combined ratio of 93%. See Note 15 — “Held for Sale and Discontinued Operations”.

II. Summary of Investment Results

White Mountains’s total investment results include continuing operations and discontinued operations. The OneBeacon and Sirius Group investment results are included in discontinued operations for each respective period.

During the third quarter of 2016, White Mountains established a portfolio of high-yield fixed maturity investments. Given the risk profile of these investments, White Mountains has included the returns associated with the high-yield fixed maturity investments with the returns from common equity securities and other long-term investments. See “NON-GAAP FINANCIAL MEASURES” on page 67.

For purposes of discussing rates of return, all percentages are presented gross of management fees and trading expenses in order to produce a better comparison to benchmark returns, while all dollar amounts are presented net of management fees and trading expenses.

A summary of White Mountains’s consolidated total operations’ pre-tax investment results, including returns from discontinued operations, for the three and six months ended June 30, 2017 and 2016 follows:

Investment Returns—Three and Six Months Ended June 30, 2017 versus Three and Six Months Ended June 30, 2016

White Mountains’s GAAP pre-tax total return on invested assets was 1.4% and 2.9% for the second quarter and first six months of 2017. White Mountains’s GAAP pre-tax total return on invested assets was 0.8% and 2.4% for the second quarter and first six months of 2016. The returns for the second quarter and first six months of 2017 were driven primarily by strong common equity securities returns while the second quarter and first six months of 2016 returns were driven primarily by a decline in interest rates.

Fixed income results

White Mountains maintains a high-quality, short-duration fixed income portfolio. As of June 30, 2017, the fixed income portfolio duration, including short-term investments but excluding high-yield fixed maturity investments, was approximately 3.0 years, compared to 2.6 years as of December 31, 2016 and 1.9 years as of June 30, 2016. Including both short-term and high-yield fixed maturity investments, duration was approximately 3.1 years as of June 30, 2017.

The increase in the duration of the fixed income portfolio since June 30, 2016 was primarily a result of establishing a new medium duration British Pound Sterling (GBP) investment grade corporate bond mandate with Legal & General Investment Management, Ltd. (“LGIM”), a third party manager. The duration of the LGIM portfolio was approximately 7.6 years as of June 30, 2017. White Mountains has entered into foreign currency forward contracts, which are recorded in other long-term investments, to manage its GBP foreign currency exposure relating to this mandate. As of June 30, 2017, these contracts had a total gross notional value of approximately $250 million (GBP 200 million) and a carrying value of ($10.6) million.

The fixed income portfolio returned 1.0% and 1.8% for the second quarter and first six months of 2017, outperforming the longer duration Bloomberg Barclays U.S. Intermediate Aggregate Index return of 0.9% and 1.6% for the comparable periods. The fixed income portfolio returned 0.8% and 2.4% for the second quarter and first six months of 2016, underperforming the longer duration Bloomberg Barclays U.S. Intermediate Aggregate Index return of 1.4% and 3.8% for the comparable periods given declining interest rates during the periods and the shorter duration positioning of the fixed income portfolio.

Common equity securities, other long-term investments, and high-yield fixed maturity investments results

White Mountains maintains a portfolio of common equity securities, other long-term investments and high-yield fixed maturity investments. White Mountains’s management believes that prudent levels of investments in common equity securities, other long-term investments and high-yield fixed maturity investments are likely to enhance long-term after-tax total returns. White Mountains’s portfolio of common equity securities, other long-term investments and high-yield fixed maturity investments represented approximately 32%, 20%, and 13% of total GAAP invested assets (including those held at OneBeacon) as of June 30, 2017, December 31, 2016, and June 30, 2016. The increase in this portfolio reflects the net addition of $495 million of investments in the second quarter of 2017, the bulk of which were added in anticipation of the removal of OneBeacon’s $442 million common equity securities, high-yield fixed maturity and other long-term investment portfolios upon the closing of the OneBeacon Transaction.

White Mountains’s portfolio of common equity securities, other long-term investments and high-yield fixed maturity investments returned 2.6% and 6.0% for the second quarter and first six months of 2017, underperforming the S&P 500 Index return of 3.1% and 9.3%. The underperformance versus the S&P 500 Index return for the second quarter was a result of unfavorable performance in other long-term investments, primarily attributable to losses from currency hedges, as well as the impact of unconsolidated private capital investments and the OneBeacon Surplus Notes, which were both relatively flat during the quarter. The underperformance was partially offset by strong common equity security performance as White Mountains’s third party managers each outperformed their respective benchmarks. For the first six months of 2017, the underperformance versus the S&P 500 Index was attributable to asset allocation, as high-yield fixed maturity investments failed to keep pace with the S&P 500 Index, and unfavorable other long-term investments results, primarily attributable to losses from currency hedges, the impact of unconsolidated private capital investments and unfavorable mark-to-market adjustments to the OneBeacon Surplus Notes.

White Mountains’s portfolio of common equity securities primarily consists of passive ETFs and publicly-traded common equity securities that are actively managed by third party managers. White Mountains’s portfolio of common equity securities and ETFs returned 4.2% and 9.6% for the second quarter and first six months of 2017, outperforming the S&P 500 Index return of 3.1% and 9.3%.

The portfolio of ETFs seeks to provide investment results that, before expenses, generally correspond to the performance of broad market indices. As of June 30, 2017 and December 31, 2016, White Mountains had $776 million and $322 million invested in S&P 500 ETFs, respectively. During the second quarter and first six months of 2017 and 2016, the ETFs essentially earned the effective index return, before expenses, over the period in which White Mountains was invested in these funds.

White Mountains’s third party manager relationships (the “actively managed portfolios”) have been with Silchester International Investors (“Silchester”), who invests in value-oriented non-U.S. equity securities through an open-ended unit trust, and Lateef Investment Management (“Lateef”), a growth at a reasonable price adviser managing a highly concentrated portfolio of mid-cap and large-cap growth companies. During the first quarter of 2017, White Mountains established a new active relationship with Lazard Asset Management (“Lazard”), to manage a Pan-European common equity portfolio, of which the majority of the securities are denominated in Euros (EUR). The actively managed portfolio of common equity securities, excluding the impact of foreign currency forward contracts, returned 6.4% and 13.7% for the second quarter and first six months of 2017, outperforming the S&P 500 Index return of 3.1% and 9.3% for the comparable periods. The actively managed portfolio of common equity securities returned -2.8% and -1.9% for the second quarter and first six months of 2016, lagging the S&P 500 Index return of 2.5% and 3.8% for the comparable periods.

White Mountains has entered into foreign currency forward contracts, which are recorded in other long-term investments, to mitigate its foreign currency exposure associated with the common equity portfolio managed by Lazard. As of June 30, 2017, these contracts had a total gross notional value of approximately $58 million (EUR 54 million) and a carrying value of $(4.4) million.

White Mountains maintains a portfolio of other long-term investments that consists primarily of hedge funds, private equity funds, unconsolidated private capital investments, the OneBeacon Surplus Notes, and various other investments. As of June 30, 2017, approximately 52% of these other long-term investments were invested in private equity funds with a general emphasis on narrow, sector-focused investments, and hedge funds with a general emphasis on long-short equities.

White Mountains’s other long-term investments returned -1.4% and -0.5% for the second quarter and first six months of 2017. The results for the second quarter of 2017 were primarily driven by the impact of currency hedges while the results for the first six months of 2017 were attributable to the impact of unconsolidated private capital investments and currency hedges as well as unfavorable mark-to-market adjustments to the OneBeacon Surplus Notes. White Mountains’s other long-term investments returned 3.9% for both the second quarter and first six months of 2016. The results for the second quarter and first six months of 2016 were driven by favorable mark-to-market adjustments to the OneBeacon Surplus Notes and solid hedge fund results.

During the third quarter of 2016, White Mountains established a new relationship with Principal Global Investors, LLC (“Principal”), a third party manager, to actively manage a relatively concentrated portfolio of high-yield fixed maturity investments. The Principal separate account is invested in issuers of U.S. dollar denominated publicly traded and 144A debt securities issued by corporations with generally at least one rating between "B-" and “BB+” inclusive by Standard and Poor’s or similar ratings from other rating agencies. The high-yield fixed maturity investments returned 3.0% and 5.2% for the second quarter and first six months of 2017, outperforming the Bloomberg Barclays U.S. High Yield Ba 2% Issuer Capped (minus Energy & Financials) Index return of 2.7% and 4.7% over the comparable periods.

Foreign Currency Translation

As of June 30, 2017, White Mountains had gross foreign currency exchange rate risk on approximately $448 million of net assets: cash and fixed maturity investments denominated in GBP managed by LGIM, cash and common equity securities denominated in EUR and other European currencies managed by Lazard, common equity securities managed by Silchester, Wobi and various other consolidated and unconsolidated private capital investments.

White Mountains entered into foreign currency forward contracts to mitigate the foreign currency exposure for the invested assets managed by LGIM and Lazard. The following table summarizes the fair value of the foreign denominated assets for these mandates, as well as the net exposure of the foreign currency forward contracts as of June 30, 2017:



$ in millions		Fair Value of Investment Portfolio		Gross Foreign Currency Forward Contract Exposure
Investment Mandate	Currency	(in USD)		(in USD)
LGIM	GBP	$	262.8	$	(260.5	)
Lazard	EUR	60.4		(62.2		)
	Totals	$	323.2	$	(322.7	)

At June 30, 2017, White Mountains’s net foreign currency exchange rate risk on net assets was approximately $125 million, net of foreign currency forward contract exposure.

Investment in Symetra Common Shares

During the third quarter of 2015, Symetra Financial Corporation (“Symetra”) announced that it entered into a definitive merger agreement with Sumitomo Life pursuant to which Sumitomo Life would acquire all of the outstanding shares of Symetra. On February 1, 2016, Symetra closed its definitive merger agreement with Sumitomo Life and White Mountains received proceeds of $658 million, or $32 per common share. White Mountains recognized $5 million in pre-tax net investment gains associated with Symetra during the first quarter of 2016. White Mountains also received a special dividend of $.50 per share as part of the transaction that was paid in the third quarter of 2015.

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 other operating subsidiaries, capital raising activities, net investment income, proceeds from sales and maturities of investments and, from time to time, proceeds from sales of operating subsidiaries. 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, distributions to non-controlling interest holders of consolidated subsidiaries, purchases of investments, payments to tax authorities, contributions to operating subsidiaries, operating expenses and, from time to time, purchases of operating subsidiaries.

Operating subsidiary level. The primary sources of cash for White Mountains’s insurance and other operating subsidiaries are expected to be premium and fee collections, net investment income, proceeds from sales and maturities of investments, contributions from holding companies, capital raising activities and, from time to time, proceeds from the sales of operating subsidiaries. The primary uses of cash are expected to be claim payments, policy acquisition costs, cost of sales, purchases of investments, payments on and repurchases/retirements of its debt obligations, distributions and tax sharing payments made to holding companies, distributions to non-controlling interest holders, operating expenses and, from time to time, purchases of operating subsidiaries.

Both internal and external forces influence White Mountains’s financial condition, results of operations and cash flows. premium and fee levels, claim settlements, cost of sales 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’s insurance 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’s cash balances, cash flows from operations, routine sales and maturities of investments and the liquidity provided by the WTM Bank Facility and the MediaAlpha Bank Facility are adequate to meet expected cash requirements for the foreseeable future on both a holding company and subsidiary level.

Dividend Capacity

Under the insurance laws of the states and jurisdictions that White Mountains’s insurance 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’s insurance and operating subsidiaries:

HG Global/BAM:

At June 30, 2017, HG Global had $619 million face value of preferred shares outstanding, of which White Mountains owned 96.9%. 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 the second quarter of 2017. As of June 30, 2017, HG Global has accrued $211 million of dividends payable to holders of its preferred shares, $204 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 to amounts held outside of the collateral trusts pursuant to the first loss reinsurance treaty (“FLRT”) with BAM. As of June 30, 2017, HG Re had statutory capital and surplus of $470 million and $490 million of assets held in the collateral trusts pursuant to the FLRT with BAM.

Effective January 1, 2014, HG Global and BAM agreed to change the interest rate on the BAM Surplus Notes for the five years ending December 31, 2018 from a fixed rate of 8.0% to a variable rate equal to the one-year U.S. treasury rate plus 300 basis points, set annually, which is 3.78% for 2017. Prior to the end of 2018, BAM has the option to extend the variable rate period for an additional three years. At the end of the variable rate period, the interest rate will be fixed at the higher of the then current variable rate or 8.0%. No payment of interest or principal on the BAM Surplus Notes may be made without the approval of the New York State Department of Financial Services. BAM has stated its intention to seek regulatory approval to pay interest and principal on its surplus notes only to the extent that its remaining qualified statutory capital (“QSC”) exceeds $500 million and its remaining QSC and other capital resources continue to support its outstanding obligations, business plan and its AA stable rating from S&P.

In order to further support BAM’s long-term capital position and business prospects, HG Global has agreed to contribute the $203 million Series A BAM Surplus Notes (“Series A Notes”) into the supplemental collateral trust (the “Supplemental Trust”) at HG Re, HG Global’s wholly owned reinsurance subsidiary. The Supplemental Trust already holds the $300 million Series B BAM Surplus Notes (“Series B Notes” and, collectively with the Series A Notes, the “Surplus Notes”). Assets held in the Supplemental Trust serve to collateralize HG Re’s obligations to BAM under the first loss reinsurance treaty between BAM and HG Re. HG Global and BAM also agreed to change the payment terms of the Series B Notes, so that payments will reduce principal and accrued interest on a pro rata basis, consistent with the payment terms on the Series A Notes. The terms of the Series B Notes had previously stipulated that payments would first reduce interest owed, then reduce principal owed once all accrued interest had been paid. Such change is subject to approval by the New York Department of Financial Services, which is expected in the third quarter of 2017.

MediaAlpha:

During the first six months of 2017, MediaAlpha paid $1.3 million of dividends, $0.8 million of which was paid to White Mountains. As of June 30, 2017, MediaAlpha had $5 million of net unrestricted cash.

Other Operations:

During the first six months of 2017, White Mountains paid a $5 million common share dividend. As of June 30, 2017, the Company and its intermediate holding companies had $1,083 million of net unrestricted cash, short-term investments and fixed maturity investments, $828 million of common equity securities and $65 million of other long-term investments included in its Other Operations segment.

Discontinued Operations - OneBeacon:

Pursuant to the OneBeacon Transaction, OneBeacon Ltd. can only pay regularly scheduled quarterly dividends to its shareholders. During the first six months of 2017, OneBeacon Ltd. paid $40 million of regular quarterly dividends to its common shareholders. White Mountains received $30 million of these dividends.

OneBeacon’s top-tier regulated U.S. insurance subsidiary, Atlantic Specialty Insurance Company (“ASIC”), has the ability to pay dividends to its immediate parent without the prior approval of regulatory authorities in an amount set by formula based on the lesser of (i) adjusted net investment income, as defined by statute, or (ii) 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus. During the first six month of 2017, ASIC paid $30 million of dividends to its immediate parent, which took into consideration the rolling 12-month portion of the statutorily-defined calculation of adjusted net investment income, including the timing of dividends paid. As of March 31, 2017, ASIC had $625 million of statutory surplus and $69 million of earned surplus.

In 2017, Split Rock has the ability to distribute statutory capital without the prior approval of the Bermuda Monetary Authority (the “BMA”), provided it does not reduce its total statutory capital, as shown in the previous year’s statutory financial statements, by 15% or more. In addition, Split Rock has the ability to pay dividends without the prior notification of regulatory authorities of up to 25% of its previous financial year’s total statutory capital and surplus, subject to meeting all appropriate liquidity and solvency requirements as specified in the Insurance Act of 1978 and the Companies Act of 1981.

As of December 31, 2016, Split Rock had $210 million of statutory capital and $60 million of statutory surplus for total statutory capital and surplus of $270 million.

Based upon the limitations described above, Split Rock currently has the ability to distribute up to $32 million of statutory capital and pay up to $60 million of dividends during 2017 without the prior approval of regulatory authorities. Split Rock did not pay any dividends or distributions during the first six months of 2017.

During the first six months of 2017, OneBeacon’s unregulated insurance subsidiaries paid $5 million of dividends to their immediate parent. As of June 30, 2017, OneBeacon’s unregulated insurance operating subsidiaries had $58 million of net unrestricted cash, short-term investments and fixed maturity investments and $71 million of other long-term investments, consisting of the OneBeacon Surplus Notes.

As of June 30, 2017, OneBeacon Ltd. and its intermediate holding companies had $51 million of net unrestricted cash, short-term investments and fixed maturity investments and $13 million of common equity securities outside of its regulated and unregulated insurance subsidiaries.

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 an unsecured revolving credit facility with a syndicate of lenders administered by Wells Fargo Bank, N.A., which has a total commitment of $425 million and a maturity date of August 14, 2018 (the “WTM Bank Facility”). As of June 30, 2017, the WTM Bank Facility was undrawn.

The WTM Bank Facility contain 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. These covenants can restrict White Mountains in several ways, including its ability to incur additional indebtedness. An uncured breach of these covenants could result in an event of default under the WTM Bank Facility, which would allow lenders to declare any amounts owed under the WTM Bank Facility to be immediately due and payable. In addition, a default under the WTM Bank Facility could occur if certain of White Mountains’s subsidiaries fail to pay principal and interest on a credit facility, mortgage or similar debt agreement (collectively, “covered debt”), or fail to otherwise comply with obligations in such covered debt agreements where such a default gives the holder of the covered debt the right to accelerate at least $75 million of principal amount of covered debt.

It is possible that, in the future, one or more of the rating agencies may lower White Mountains’s 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.

On May 12, 2017, MediaAlpha entered into a secured credit facility (the “MediaAlpha Bank Facility”) with Western Alliance Bank, which has a total commitment of $20 million and has a maturity date of May 12, 2020. The MediaAlpha Bank Facility replaced MediaAlpha’s previous credit facility (the “Previous MediaAlpha Bank Facility”), which had a total commitment of $20 million. The MediaAlpha Bank Facility consists of a $5 million term loan facility, which has an outstanding balance of $5 million as of June 30, 2017, and a revolving credit facility for $15 million, which has an outstanding balance of $6 million as of June 30, 2017. During the six months ended June 30, 2017, MediaAlpha repaid $13 million under the Previous MediaAlpha Bank Facility. The MediaAlpha Bank Facility carries a variable interest rate that is based on the Prime Rate, as published by the Wall Street Journal, plus a spread of 1.5% on the term loan facility and 0.25% on the revolving credit facility as of as of June 30, 2017.

Discontinued Operations

OneBeacon Ltd. and OneBeacon U.S. Holdings, Inc. (“OBH”), as co-borrowers and co-guarantors, have a revolving credit facility administered by U.S. Bank N.A. and also including BMO Harris Bank N.A., which has a total commitment of $65 million and has a maturity date of September 29, 2019 (the “OneBeacon Bank Facility”). As of June 30, 2017, the OneBeacon Bank Facility was undrawn.

The OneBeacon Bank Facility contain 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. These covenants can restrict White Mountains in several ways, including its ability to incur additional indebtedness. An uncured breach of these covenants could result in an event of default under the OneBeacon Bank Facility, which would allow lenders to declare any amounts owed under the OneBeacon Bank Facility to be immediately due and payable. In addition, a default under the OneBeacon Bank Facility could occur if OneBeacon fails to pay principal and interest on a credit facility, mortgage or similar debt agreement (collectively, “covered debt”), or fails to otherwise comply with obligations in such covered debt agreements where such a default gives the holder of the covered debt the right to accelerate at least $75 million of principal amount of covered debt.

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 “OBH Senior Notes”). The net proceeds from the issuance of the OBH Senior Notes were used to repurchase OBH’s previously issued senior notes. The 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 OBH Senior Notes were issued under indentures that contain restrictive covenants which, among other things, limit the ability of OneBeacon Ltd., OBH, and their respective subsidiaries to create liens and enter into sale and leaseback transactions and limits the ability of OneBeacon Ltd. and OBH to consolidate, merge or transfer its properties and assets. The indentures do not contain any financial ratios or specified levels of net worth or liquidity to which OneBeacon Ltd. or OBH must adhere. In addition, a failure by OneBeacon Ltd., OBH or their respective subsidiaries to pay principal and interest on covered debt, where such failure results in the acceleration of at least $75 million of the principal amount of covered debt, could trigger the acceleration of the OBH Senior Notes.

Pursuant to its merger agreement with Intact (the “Merger Agreement”), OneBeacon, without the prior written consent of Intact, cannot take certain actions until the effective time of the merger or termination of the Merger Agreement, including incurring any additional indebtedness, issuing equity, selling any material properties or assets, acquiring assets or making, or committing to make, capital expenditures, in each case except as permitted pursuant to the Merger Agreement.

Covenant Compliance

As of June 30, 2017, White Mountains was in compliance with all of the covenants under all of its debt instruments and expects to remain in compliance for the foreseeable future.

As of June 30, 2017, OneBeacon was in compliance with all of the covenants under the OBH Senior Notes and the OneBeacon Credit Facility. The closing of the OneBeacon Acquisition will not result in any default under the indenture for the 2012 Senior Notes. While the closing of the OneBeacon Acquisition would constitute an event of default under the Credit Facility, OneBeacon intends to voluntarily terminate the Credit Facility, which is undrawn, effective as of the closing.

Share Repurchases

White Mountains’s board of directors has authorized the Company to repurchase its common shares from time to time, subject to market conditions. The repurchase authorizations do not have a stated expiration date. As of June 30, 2017, White Mountains may repurchase an additional 878,130 shares under these board authorizations.

Cash Flows

Detailed information concerning White Mountains’s cash flows during the six months ended June 30, 2017 and 2016 follows:

Cash flows from continuing operations for the six months ended June 30, 2017 and June 30, 2016

Net cash used for continuing operations was $66 million in the first six months of 2017 and $121 million in the first six months of 2016. Cash used for continuing operations was lower in the first six months of 2017 compared to the first six months of 2016, primarily due to payments related to the settlement of certain liabilities and transaction costs in connection with the Sirius Group sale in the first six months of 2016. This decrease in cash used from operations was partially offset by an increase in incentive compensation and employee retirement payments in the first six months of 2017 relative to the first six months of 2016. White Mountains made long-term incentive payments totaling $22 million and $41 million during the first six months of 2017 and the first six months of 2016. During the first six months of 2017, White Mountains also paid $28 million in cash related to the departures of the Company’s former Chairman and CEO and former CFO. White Mountains does not believe these trends will have a meaningful impact on its future liquidity or its ability to meet its future cash requirements.

FAIR VALUE CONSIDERATIONS

General

White Mountains records certain assets and liabilities at 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.

Invested Assets

White Mountains’s invested assets that are measured at fair value include fixed maturity investments, common equity 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 benchmark yields, reported trades, broker dealer quotes, issuer spreads, benchmark securities, bids, offers, prepayment speeds, reference data including research publications 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 June 30, 2017, approximately 91% of the investment portfolio (including investments in discontinued operations) recorded at fair value was priced based upon quoted market prices or other observable inputs. Investments valued using Level 1 inputs include fixed maturity securities, primarily investments in U.S. Treasuries, common equity securities and short-term investments, which include U.S. Treasury Bills. Investments valued using Level 2 inputs comprise fixed maturity securities including debt securities issued by corporations, mortgage and asset-backed securities, municipal obligations and foreign government, agency and provisional obligations. Fair value estimates for investments that trade infrequently and have few or no observable market prices are classified as Level 3 measurements. Investments valued using Level 2 inputs also include certain ETFs that track U.S. stock indices such as the S&P 500 but are traded on foreign exchanges and that management values using the fund’s published NAV to account for the difference in market close times. Level 3 fair value estimates based upon unobservable inputs include White Mountains’s investments in surplus notes, as well as certain investments in fixed maturity investments, equity securities and other long-term investments where quoted market prices are unavailable or are not considered reasonable.

White Mountains determines when transfers between levels have occurred as of the beginning of the period. 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 methodologies and observable inputs such as benchmark yields, reported trades, broker dealer quotes, issuer spreads, bids, offers, credit ratings prepayment speeds, reference data including research publications 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 pricing methodologies and the pricing services’ quality control processes and procedures on at least an annual basis, comparison of market prices to prices obtained from alternative 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. Also considered outliers are prices that have not changed from period to period and prices that have trended unusually compared to market conditions. In circumstances where the results of White Mountains’s review process do not appear to support the market price provided by the pricing services, White Mountains challenges the price. The fair values of such securities are considered to be Level 3 measurements.

NON-GAAP FINANCIAL MEASURES

This report includes six non-GAAP financial measures, adjusted book value per share, percentage change in adjusted book value per share including the estimated gain from OneBeacon and excluding the new adjustments from HG Global/BAM, adjusted capital, return on common equity securities and other long-term investments including high-yield fixed maturity investments, return on fixed maturity investments excluding high-yield fixed maturity investments, and EBITDA that have been reconciled to their most comparable GAAP financial measures.

•

Adjusted book value per share is a non-GAAP financial measure, which is derived by adjusting the GAAP book value per share numerator to (i) include a discount for the time value of money on the BAM Surplus Notes and (ii) add back the unearned premium reserve, net of deferred acquisition costs, at HG Global. 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 calculation of adjusted book value per share also includes the dilutive effects of outstanding non-qualified options for periods prior to January 20, 2017, the expiration date of the non-qualified options.

Beginning in the second quarter of 2017, in its calculation of adjusted book value per share, White Mountains has included a time value of money discount relating to the expected future payments on the BAM Surplus Notes. Under GAAP, White Mountains is required to carry the BAM Surplus Notes, including accrued interest, at nominal value with no consideration for time value of money. Based on a debt service model that forecasts operating results for BAM through maturity of the surplus notes, the present value of the BAM Surplus Notes, including accrued interest, is estimated to be $172 million less than the nominal GAAP carrying value. White Mountains has also included the value of HG Global’s unearned premium reserve net of deferred acquisition costs. White Mountains believes these adjustments are useful to management and investors in analyzing the intrinsic value of HG Global, including the intrinsic value of the surplus notes and HG Global’s reinsurance subsidiary’s (HG Re’s) in-force business. The reconciliation of GAAP book value per share to adjusted book value per share is included on page 47.


•	The growth in adjusted book value per share included on page 45 includes the estimated gain from the OneBeacon Transaction and excludes the impact of the new adjustments related to HG Global/BAM. A reconciliation from GAAP to the reported percentage is as follows:



	As of June 30, 2017			As of March 31, 2017		Growth %
GAAP book value per share	$	797.80		$	792.77	0.6	%
Adjustments to book value per share (see reconciliation on page 47)	(17.80		)	6.06
Adjusted book value per share	780.00			798.83		-2.4	%
Estimated gain from OneBeacon Transaction	116.00			107.00
Adjusted book value per share including the estimated gain from the OneBeacon Transaction	896.00			905.83		-1.1	%
Reverse new adjustments related to HG Global/BAM (see page 47)	22.62			N/A
Adjusted book value per share including the estimated gain from the OneBeacon Transaction and excluding the new adjustments related to HG Global/BAM	$	918.62		$	905.83	1.4	%

•

Total capital at White Mountains is comprised of White Mountains’s common shareholders’ equity, debt and non-controlling interests other than non-controlling interests attributable to mutuals and reciprocals. Total adjusted capital is a non-GAAP financial measure, which is derived by adjusting total capital to (i) include a discount for the time value of money on the BAM Surplus Notes and (ii) add back the unearned premium reserve, net of deferred acquisition costs, at HG Global. The reconciliation of total capital to total adjusted capital is included on page 62.

•

In the third quarter of 2016, White Mountains purchased high-yield fixed maturity investments, which are U.S. dollar denominated publicly traded and 144A debt securities issued by corporations with generally at least one rating between “B-” and “BB+” inclusive by S&P or similar ratings from other rating agencies. Given the risk profile of these investments, the returns on high-yield fixed maturity investments have been included with the returns on common equity securities and other long-term investments and excluded from the returns on fixed income investments. A reconciliation of GAAP returns to the reported returns are as follows:



	June 30, 2017
	Three Months Ended							Six Months Ended
	GAAP return		Impact of high-yield fixed maturity investments ⁽¹⁾			Reported return		GAAP return		Impact of high-yield fixed maturity investments ⁽¹⁾			Reported return
Common equity securities and other long-term investment returns	2.5	%	0.1		%	2.6	%	6.3	%	(0.3	)	%	6.0	%
Fixed income investment returns	1.1	%	(0.1	)	%	1.0	%	2.1	%	(0.3	)	%	1.8	%

⁽¹⁾High-yield fixed maturity investments returned 3.0% and 5.2% for the second quarter and first six months of 2017.

•

In the second quarter of 2017, MediaAlpha became a reportable segment, and White Mountains has included MediaAlpha’s EBITDA calculation as a non-GAAP financial measure. EBITDA is defined as net income (loss) excluding interest expense on debt, income tax benefit (expense), depreciation and amortization. White Mountains believes that this non-GAAP financial measure is useful to management and investors in analyzing MediaAlpha’s economic performance without the effects of interest rates, levels of debt, effective tax rates, depreciation and amortization resulting from purchase accounting. In addition, White Mountains believes that investors use EBITDA as a supplemental measurement to evaluate the overall operating performance of companies within the same industry. See page 55 for the reconciliation of MediaAlpha’s GAAP net income to EBITDA.

CRITICAL ACCOUNTING ESTIMATES

As described in White Mountains’s Annual Report on Form 10-K for the year ended December 31, 2016 under “CRITICAL ACCOUTNING ESTIMATES”, the determination of the recoverability of the BAM Surplus Notes is based on a debt service model that forecasts operating results for BAM through maturity of the BAM Surplus Notes. In its most recent update of this model, White Mountains has (1) reflected the impact of the changes to the terms of the BAM Surplus Notes on expected future payments and (2) made more conservative assumptions about BAM’s future operating results, specifically forecasted increases in annual par insured volume and total premium rates. As a result, although the model continues to project that BAM can begin making payments on the BAM Surplus Notes in 2019, White Mountains now projects that the BAM Surplus Notes will be fully repaid approximately eight years prior to final maturity, which is seven years later than projected under the previous forecast.

Refer to the Company’s 2016 Annual Report on Form 10-K for a complete discussion regarding White Mountains’s critical accounting estimates.

Part II.	OTHER INFORMATION


Item 1.	Legal Proceedings.

Litigation Related to the OneBeacon Transaction

Tribune Company

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 and OneBeacon-sponsored benefit plans received approximately $32.0 million, for Tribune common stock tendered in connection with the LBO.

Item 1A. Risk Factors.

OneBeacon’s merger with Intact is subject to conditions, including certain conditions that may not be satisfied. Failure to complete the merger could adversely affect our financial position and the value of OneBeacon’s business.

Completion of OneBeacon’s merger with Intact is subject to the satisfaction or waiver of a number of closing conditions, including the receipt of required regulatory approvals or consents, including from the domestic insurance regulators of the states of Delaware, Pennsylvania, Texas and New York, the absence of any injunction or restraint enjoining the merger, as well as other conditions to closing that are customary in public company mergers. Many of the conditions to closing are outside of the Company’s control and may prevent or otherwise adversely affect the completion of the merger.
