REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of PartnerRe Ltd.

We have reviewed the accompanying condensed consolidated balance sheet of PartnerRe Ltd. and subsidiaries (the “Company”) as of September 30, 2013, and the related condensed consolidated statements of operations and comprehensive income for the three-month and nine-month periods ended September 30, 2013 and 2012, and of shareholders’ equity, and of cash flows for the nine-month periods ended September 30, 2013 and 2012. These interim condensed consolidated financial statements are the responsibility of the Company’s management.

We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to such condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of PartnerRe Ltd. and subsidiaries as of December 31, 2012 and the related consolidated statements of operations and comprehensive income (loss), shareholders’ equity, and of cash flows for the year then ended (not presented herein); and in our report dated February 26, 2013, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2012 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Organization

PartnerRe Ltd. (the Company) predominantly provides reinsurance and certain specialty insurance lines on a worldwide basis through its principal wholly-owned subsidiaries, including Partner Reinsurance Company Ltd., Partner Reinsurance Europe SE and Partner Reinsurance Company of the U.S. Risks reinsured include, but are not limited to, property, casualty, motor, agriculture, aviation/space, catastrophe, credit/surety, engineering, energy, marine, specialty property, specialty casualty, multiline and other lines, mortality, longevity, accident and health and alternative risk products. The Company’s alternative risk products include weather and credit protection to financial, industrial and service companies on a worldwide basis.

Effective December 31, 2012, the Company completed the acquisition of Presidio Reinsurance Group, Inc. (Presidio), a California-based U.S. specialty accident and health reinsurance and insurance writer. The Condensed Consolidated Statements of Operations and Cash Flows include the results of Presidio from January 1, 2013.

2. Significant Accounting Policies

The Company’s Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. The Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries. Intercompany accounts and transactions have been eliminated. To facilitate comparison of information across periods, certain reclassifications have been made to prior year amounts to conform to the current year’s presentation.

The preparation of financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While Management believes that the amounts included in the Condensed Consolidated Financial Statements reflect its best estimates and assumptions, actual results could differ from those estimates. The Company’s principal estimates include:

•

Unpaid losses and loss expenses;

•

Policy benefits for life and annuity contracts;

•

Gross and net premiums written and net premiums earned;

•

Recoverability of deferred acquisition costs;

•

Recoverability of deferred tax assets;

•

Valuation of goodwill and intangible assets; and

•

Valuation of certain assets and derivative financial instruments that are measured using significant unobservable inputs.

In the opinion of Management, all adjustments (which include normal recurring adjustments) necessary for a fair presentation of results for the interim periods have been made. As the Company’s reinsurance operations are exposed to low-frequency, high-severity risk events, some of which are seasonal, results for certain interim periods may include unusually low loss experience, while results for other interim periods may include significant catastrophic losses. Consequently, the Company’s results for interim periods are not necessarily indicative of results for the full year. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

3. Fair Value

(a) Fair Value of Financial Instrument Assets

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value by maximizing the use of observable inputs and minimizing the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about what market participants would use in pricing the asset or liability based on the best information available in the circumstances. The level in the hierarchy within which a given fair value measurement falls is determined based on the lowest level input that is significant to the measurement.

The Company determines the appropriate level in the hierarchy for each financial instrument that it measures at fair value. In determining fair value, the Company uses various valuation approaches, including market, income and cost approaches. The hierarchy is broken down into three levels based on the observability of inputs as follows:

•

Level 1 inputs—Unadjusted, quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

The Company’s financial instruments that it measures at fair value using Level 1 inputs generally include: equities and real estate investment trusts listed on a major exchange, exchange traded funds and exchange traded derivatives, including futures that are actively traded.

•

Level 2 inputs—Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets and significant directly or indirectly observable inputs, other than quoted prices, used in industry accepted models.

The Company’s financial instruments that it measures at fair value using Level 2 inputs generally include: U.S. government issued bonds; U.S. government sponsored enterprises bonds; U.S. state, territory and municipal entities bonds; Non-U.S. sovereign government, supranational and government related bonds consisting primarily of bonds issued by non-U.S. national governments and their agencies, non-U.S. regional governments and supranational organizations; investment grade and high yield corporate bonds; catastrophe bonds; mortality bonds; asset-backed securities; mortgage-backed securities; certain equities traded on foreign exchanges; certain fixed income mutual funds; foreign exchange forward contracts; over-the-counter derivatives such as foreign currency option contracts, credit default swaps, interest rate swaps and to-be-announced mortgage-backed securities (TBAs).

•

Level 3 inputs—Unobservable inputs.

The Company’s financial instruments that it measures at fair value using Level 3 inputs generally include: inactively traded fixed maturities including U.S. state, territory and municipal bonds; privately issued corporate securities; special purpose financing asset-backed bonds; unlisted equities; real estate and certain other mutual fund investments; inactively traded weather derivatives; notes and loan receivables, notes securitizations, annuities and residuals, private equities and longevity and other total return swaps.

The tables above do not include financial instruments that are measured using unobservable inputs (Level 3) where the unobservable inputs were obtained from external sources and used without adjustment. These financial instruments include mortality bonds (included within corporate fixed maturities), mutual fund investments (included within equities), and certain insurance-linked securities (included within other invested assets).

The Company has established a Valuation Committee which is responsible for determining the Company’s invested asset valuation policy and related procedures, for reviewing significant changes in the fair value measurements of securities classified as Level 3 from period to period, and for reviewing in accordance with the invested asset valuation policy an independent internal peer analysis that is performed on the fair value measurements of all securities that are classified as Level 3. The Valuation Committee is comprised of members of the Company’s senior management team and meets on a quarterly basis. The Company’s invested asset valuation policy is monitored by the Company’s Audit Committee of the Board of Directors (Board) and approved annually by the Company’s Risk and Finance Committee of the Board.

Changes in the fair value of the Company’s financial instruments subject to the fair value option during the three months and nine months ended September 30, 2013 and 2012 were as follows (in thousands of U.S. dollars):


	For the three months ended September 30, 2013			For the three months ended September 30, 2012		For the nine months ended September 30, 2013			For the nine months ended September 30, 2012

Total	$	11,482		$	212,305	$	(492,077	)	$	337,880

All of the above changes in fair value are included in the Condensed Consolidated Statements of Operations under the caption Net realized and unrealized investment gains (losses).

The following methods and assumptions were used by the Company in estimating the fair value of each class of financial instrument recorded in the Condensed Consolidated Balance Sheets. There have been no material changes in the Company’s valuation techniques during the periods presented.

Fixed maturities

•

U.S. government and government sponsored enterprises—U.S. government and government sponsored enterprises securities consist primarily of bonds issued by the U.S. Treasury, corporate debt securities issued by the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation, the Federal Home Loan Bank and the Private Export Funding Corporation. These securities are generally priced by independent pricing services. The independent pricing services may use actual transaction prices for securities that have been actively traded. For securities that have not been actively traded, each pricing source has its own proprietary method to determine the fair value, which may incorporate option adjusted spreads (OAS), interest rate data and market news. The Company generally classifies these securities in Level 2.

•

U.S. states, territories and municipalities—U.S. states, territories and municipalities securities consist primarily of bonds issued by U.S. states, territories and municipalities. These securities are generally priced by independent pricing services using the techniques described for U.S. government and government sponsored enterprises above. The Company generally classifies these securities in Level 2. Certain of the bonds that are issued by municipal housing authorities are not actively traded and are priced based on internal models using unobservable inputs. Accordingly, the Company classifies these securities in Level 3. The significant unobservable input used in the fair value measurement of these U.S. states, territories and municipalities securities classified as Level 3 is credit spreads. A significant increase (decrease) in credit spreads in isolation could result in a significantly lower (higher) fair value measurement.

•

Non-U.S. sovereign government, supranational and government related—Non-U.S. sovereign government, supranational and government related securities consist primarily of bonds issued by non-U.S. national governments and their agencies, non-U.S. regional governments and supranational organizations. These securities are generally priced by independent pricing services using the techniques described for U.S. government and government sponsored enterprises above. The Company generally classifies these securities in Level 2.

•

Corporate—Corporate securities consist primarily of bonds issued by U.S. and foreign corporations covering a variety of industries and issuing countries. These securities are generally priced by independent pricing services and brokers. The pricing provider incorporates information including credit spreads, interest rate data and market news into the valuation of each security. The Company generally classifies these securities in Level 2. When a corporate security is inactively traded or the valuation model uses unobservable inputs, the Company classifies the security in Level 3.

•

Asset-backed securities—Asset-backed securities primarily consist of bonds issued by U.S. and foreign corporations that are backed by student loans, automobile loans, credit card receivables, equipment leases, and special purpose financing. With the exception of special purpose financing, these asset-backed securities are generally priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. The Company generally classifies these securities in Level 2. Special purpose financing securities are generally inactively traded and are priced based on valuation models using unobservable inputs. The Company generally classifies these securities in Level 3. The significant unobservable inputs used in the fair value measurement of these asset-backed securities classified as Level 3 are prepayment speeds and credit spreads. Significant increases (decreases) in these prepayment speeds and credit spreads in isolation could result in a significantly lower (higher) fair value measurement.

•

Residential mortgage-backed securities—Residential mortgage-backed securities primarily consist of bonds issued by the Government National Mortgage Association, the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation, as well as private, non-agency issuers. With the exception of private, non-agency issuers, these residential mortgage-backed securities are generally priced by independent pricing services and brokers. When current market trades are not available, the pricing provider or the Company will employ proprietary models with observable inputs including other trade information, prepayment speeds, yield curves and credit spreads. The Company generally classifies these securities in Level 2.

•

Other mortgage-backed securities—Other mortgage-backed securities primarily consist of commercial mortgage-backed securities. These securities are generally priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. The Company generally classifies these securities in Level 2.

In general, the methods employed by the independent pricing services to determine the fair value of the securities that have not been actively traded involve the use of “matrix pricing” in which the independent pricing source applies the credit spread for a comparable security that has traded recently to the current yield curve to determine a reasonable fair value. The Company uses a pricing service ranking to consistently select the most appropriate pricing service in instances where it receives multiple quotes on the same security. When fair values are unavailable from these independent pricing sources, quotes are obtained directly from broker-dealers who are active in the corresponding markets. Most of the Company’s fixed maturities are priced from the pricing services or dealer quotes. The Company will typically not make adjustments to prices received from pricing services or dealer quotes; however, in instances where the quoted external price for a security uses significant unobservable inputs, the Company will classify that security as Level 3. The methods used to develop and substantiate the unobservable inputs used are based on the Company’s valuation policy and are dependent upon the facts and circumstances surrounding the individual investments which are generally transaction specific. The Company’s inactively traded fixed maturities are classified as Level 3. For all fixed maturity investments, the bid price is used for estimating fair value.

To validate prices, the Company compares the fair value estimates to its knowledge of the current market and will investigate prices that it considers not to be representative of fair value. The Company also reviews an internally generated fixed maturity price validation report which converts prices received for fixed maturity investments from the independent pricing sources and from broker-dealers quotes and plots OAS and duration on a sector and rating basis. The OAS is calculated using established algorithms developed by an independent risk analytics platform vendor. The OAS on the fixed maturity price validation report are compared for securities in a similar sector and having a similar rating, and outliers are identified and investigated for price reasonableness. In addition, the Company completes quantitative analyses to compare the performance of each fixed maturity investment portfolio to the performance of an appropriate benchmark, with significant differences identified and investigated.

Short term investments

Short term investments are valued in a manner similar to the Company’s fixed maturity investments and are generally classified in Level 2.

Equities

Equity securities include U.S. and foreign common and preferred stocks, mutual funds and exchange traded funds. Equities and exchange traded funds are generally classified in Level 1 as the Company uses prices received from independent pricing sources based on quoted prices in active markets. Equities classified as Level 2 are generally mutual funds invested in fixed income securities, where the net asset value of the fund is provided on a daily basis, and common stocks traded in inactive markets. Equities classified as Level 3 are generally mutual funds invested in securities other than the common stock of publicly traded companies, where the net asset value is not provided on a daily basis, and inactively traded common stocks. The significant unobservable inputs used in the fair value measurement of inactively traded common stocks classified as Level 3 include market return information, weighted using management’s judgment, from comparable selected publicly traded companies in the same industry, in a similar region and of a similar size, including net income multiples, tangible book value multiples, revenue multiples and adjusted earnings multiples. Significant increases (decreases) in any of these inputs could result in a significantly higher (lower) fair value measurement. Significant unobservable inputs used in measuring the fair value measurement of inactively traded common stocks also include a liquidity discount. A significant increase (decrease) in the liquidity discount could result in a significantly lower (higher) fair value measurement.

To validate prices, the Company completes quantitative analyses to compare the performance of each equity investment portfolio to the performance of an appropriate benchmark, with significant differences identified and investigated.

Other invested assets

The Company’s exchange traded derivatives, such as futures are generally classified as Level 1 as their fair values are quoted prices in active markets. The Company’s foreign exchange forward contracts, foreign currency option contracts, credit default swaps, interest rate swaps and TBAs are generally classified as Level 2 within the fair value hierarchy and are priced by independent pricing services.

Included in the Company’s Level 3 classification, in general, are certain inactively traded weather derivatives; notes and loan receivables, notes securitizations, annuities and residuals, private equities and longevity and other total return swaps. For Level 3 instruments, the Company will generally (i) receive a price based on a manager’s or trustee’s valuation for the asset; (ii) perform a

liquidation analysis using investee company financial statements, that are generally audited on an annual basis, adjusted if necessary for the recoverability of intangible assets; (iii) develop an internal discounted cash flow model to measure fair value; or (iv) use market return information, adjusted if necessary and weighted using management’s judgment, from comparable selected publicly traded equity funds, in a similar region and of a similar size. Where the Company receives prices from the manager or trustee, these prices are based on the manager’s or trustee’s estimate of fair value for the assets and are generally audited on an annual basis. Where the Company develops its own discounted cash flow models, the inputs will be specific to the asset in question, based on appropriate historical information, adjusted as necessary, and using appropriate discount rates. The significant unobservable inputs used in the fair value measurement of other invested assets classified as Level 3 include credit spreads, prepayment speeds, constant default rates and gross revenue to fair value ratios. Significant increases (decreases) in any of these inputs in isolation could result in a significantly lower (higher) fair value measurement. Significant unobservable inputs used in the fair value measurement of other invested assets classified as Level 3 also include an assessment of the recoverability of intangible assets and market return information, weighted using management’s judgment, from comparable selected publicly traded companies in the same industry, in a similar region and of a similar size. Significant increase (decrease) in these inputs in isolation could result in a significantly higher (lower) fair value measurement. As part of the Company’s modeling to determine the fair value of an investment, the Company considers counterparty credit risk as an input to the model, however, the majority of the Company’s counterparties are investment grade rated institutions and the failure of any one counterparty would not have a significant impact on the Company’s consolidated financial statements.

To validate prices, the Company will compare them to benchmarks, where appropriate, or to the business results generally within that asset class and specifically to those particular assets.

Funds held – directly managed

The segregated investment portfolio underlying the funds held – directly managed account is comprised of fixed maturities and other invested assets which are fair valued on a basis consistent with the methods described above. Substantially all fixed maturities and short-term investments within the funds held – directly managed account are classified as Level 2 within the fair value hierarchy.

The other invested assets within the segregated investment portfolio underlying the funds held – directly managed account, which are classified as Level 3 investments, are primarily real estate mutual fund investments carried at fair value. For the real estate mutual fund investments, the Company receives a price based on the real estate fund manager’s valuation for the asset and further adjusts the price, if necessary, based on appropriate current information on the real estate market. Significant increases (decreases) to the adjustment to the real estate fund manager’s valuation could result in a significantly lower (higher) fair value measurement.

To validate prices within the segregated investment portfolio underlying the funds held – directly managed account, the Company utilizes the methods described above.

(b) Fair Value of Financial Instrument Liabilities

At September 30, 2013 and December 31, 2012, the fair values of financial instrument liabilities recorded in the Condensed Consolidated Balance Sheets approximate their carrying values, with the exception of the debt related to senior notes (Senior Notes) and the debt related to capital efficient notes (CENts).

The following methods and assumptions were used by the Company in estimating the fair value of each class of financial instrument liability recorded in the Condensed Consolidated Balance Sheets for which the Company does not measure that instrument at fair value:

•

the fair value of the Senior Notes was calculated based on discounted cash flow models using observable market yields and contractual cash flows based on the aggregate principal amount outstanding of $250 million from PartnerRe Finance A LLC and $500 million from PartnerRe Finance B LLC at September 30, 2013 and December 31, 2012; and

•

the fair value of the CENts was calculated based on discounted cash flow models using observable market yields and contractual cash flows based on the aggregate principal amount outstanding of $63 million from PartnerRe Finance II Inc. at September 30, 2013 and December 31, 2012.

The carrying values and fair values of the Senior Notes and CENts at September 30, 2013 and December 31, 2012 were as follows (in thousands of U.S. dollars):


	September 30, 2013				December 31, 2012
	Carrying Value		Fair Value		Carrying Value		Fair Value
Debt related to senior notes ⁽¹⁾	$	750,000	$	852,507	$	750,000	$	859,367
Debt related to capital efficient notes ⁽²⁾		63,384		61,853		63,384		66,990

(1)

PartnerRe Finance A LLC and PartnerRe Finance B LLC, the issuers of the Senior Notes, do not meet consolidation requirements under U.S. GAAP. Accordingly, the Company shows the related intercompany debt of $750 million in its Condensed Consolidated Balance Sheets at September 30, 2013 and December 31, 2012.

(2)

PartnerRe Finance II Inc., the issuer of the CENts, does not meet consolidation requirements under U.S. GAAP. Accordingly, the Company shows the related intercompany debt of $71 million in its Condensed Consolidated Balance Sheets at September 30, 2013 and December 31, 2012.

At September 30, 2013, the Company’s debt related to the Senior Notes and CENts was classified as Level 2 in the fair value hierarchy.

Disclosures about the fair value of financial instrument liabilities exclude insurance contracts and certain other financial instruments.

4. Derivatives

The Company’s derivative instruments are recorded in the Condensed Consolidated Balance Sheets at fair value, with changes in fair value mainly recognized in either net foreign exchange gains and losses or net realized and unrealized investment gains and losses in the Condensed Consolidated Statements of Operations or accumulated other comprehensive income or loss in the Condensed Consolidated Balance Sheets, depending on the nature of the derivative instrument. The Company’s objectives for holding or issuing these derivatives are as follows:

Foreign Exchange Forward Contracts

The Company utilizes foreign exchange forward contracts as part of its overall currency risk management and investment strategies. From time to time, the Company also utilizes foreign exchange forward contracts to hedge a portion of its net investment exposure resulting from the translation of its foreign subsidiaries and branches whose functional currency is other than the U.S. dollar.

Foreign Currency Option Contracts and Futures Contracts

The Company utilizes foreign currency option contracts to mitigate foreign currency risk. The Company uses exchange traded treasury note futures contracts to manage portfolio duration and commodity and equity futures to hedge certain investments. The Company also uses commodities futures to replicate the investment return on certain benchmarked commodities.

Credit Default Swaps

The Company purchases protection through credit default swaps to mitigate the risk associated with its underwriting operations, most notably in the credit/surety line, and to manage market exposures.

The Company also assumes credit risk through credit default swaps to replicate investment positions. The original term of these credit default swaps is generally five years or less and there are no recourse provisions associated with these swaps. While the Company would be required to perform under exposure assumed through credit default swaps in the event of a default on the underlying issuer, no issuer was in default at September 30, 2013. The counterparties on the Company’s assumed credit default swaps are all investment grade rated financial institutions.

Insurance-Linked Securities

The Company enters into various weather derivatives and longevity total return swaps for which the underlying risks reference parametric weather risks for the weather derivatives and longevity risk for the longevity total return swaps.

Total Return and Interest Rate Swaps and Interest Rate Derivatives

The Company enters into total return swaps referencing various project, investments and principal finance obligations. The Company enters into interest rate swaps to mitigate the interest rate risk on certain of the total return swaps and certain fixed maturity investments. The Company also uses other interest rate derivatives to mitigate exposure to interest rate volatility.

To-Be-Announced Mortgage-Backed Securities

The Company utilizes TBAs as part of its overall investment strategy and to enhance investment performance.

The net fair values and the related net notional values of derivatives included in the Company’s Condensed Consolidated Balance Sheets at September 30, 2013 and December 31, 2012 were as follows (in thousands of U.S. dollars):

(1)

At September 30, 2013 and December 31, 2012, insurance-linked securities include a longevity swap for which the notional amount is not reflective of the overall potential exposure of the swap. As such, the Company has included the probable maximum loss under the swap within the net notional exposure as an approximation of the notional amount.

(2)

The Company enters into interest rate swaps to mitigate notional exposures on certain total return swaps and certain fixed maturities. Accordingly, the notional value of interest rate swaps on certain total return swaps is not presented separately in the table.

The fair value of all derivatives at September 30, 2013 and December 31, 2012 is recorded in Other invested assets in the Company’s Condensed Consolidated Balance Sheets. At September 30, 2013 and December 31, 2012, none of the Company’s derivatives were designated as hedges.

The gains and losses in the Condensed Consolidated Statements of Operations for derivatives not designated as hedges for the three months and nine months ended September 30, 2013 and 2012 were as follows (in thousands of U.S. dollars):


	For the three			For the three			For the nine			For the nine

Offsetting of Derivatives

The gross and net fair values of derivatives that are subject to offsetting in the Condensed Consolidated Balance Sheets at September 30, 2013 and December 31, 2012 were as follows (in thousands of U.S. dollars):


				Gross		Net amounts of			Gross amounts not offset
	Gross			amounts		assets/ liabilities			in the balance sheet

Total derivative liabilities	$	(30,502	)	$	—	$	(30,502	)	$	12,051		$	—	$	(18,451	)

(1)	Amounts include all derivative instruments, irrespective of whether there is a legally enforceable master netting arrangement in place.

Generally, credit default swaps, total return swaps and interest rate swaps are subject to a master netting or similar agreements as they are entered into using International Swaps and Derivatives Association agreements which provide for the ability to settle the derivative asset and liability with each counterparty on a net basis. Futures contracts and foreign exchange forward contracts are traded on a regulated exchange which permits netting.

5. Shareholders’ Equity

Series F Non-Cumulative Redeemable Preferred Shares

On February 14, 2013, the Company issued Series F non-cumulative redeemable preferred shares (Series F preferred shares) as follows (in millions of U.S. dollars or shares, except percentage amounts):


	Series F
Date of issuance		February 2013
Number of preferred shares issued		10.0
Annual dividend rate		5.875	%
Total consideration	$	242.3
Underwriting discounts and commissions	$	7.7
Aggregate liquidation value	$	250.0

The net proceeds received were used, together with available cash, to redeem the Series C Cumulative Redeemable Preferred Shares (Series C preferred shares). On or after March 1, 2018, the Company may redeem the Series F preferred shares in whole at any time, or in part from time to time, at $25.00 per share, plus an amount equal to the portion of the quarterly dividend attributable to the then-current dividend period to, but excluding, the redemption date. The Company may also redeem the Series F preferred shares at any time upon the occurrence of a certain “capital disqualification event” or certain changes in tax law. Dividends on the Series F preferred shares are non-cumulative and are payable quarterly.

In the event of liquidation of the Company, the Series F preferred shares rank on parity with each of the other series of preferred shares and would rank senior to the common shares, and holders thereof would receive a distribution of $25.00 per share, or the aggregate liquidation value, plus declared but unpaid dividends, if any.

Series C Cumulative Redeemable Preferred Shares

On March 18, 2013, the Company redeemed the Series C preferred shares for the aggregate liquidation value of $290 million plus accrued dividends. In connection with the redemption, the Company recognized a loss of $9.1 million related to the original issuance costs of the Series C preferred shares and calculated as a difference between the redemption price and the consideration received after underwriting discounts and commissions. The loss was recognized in determining the net income attributable to PartnerRe Ltd. common shareholders.

6. Net Income per Share

The reconciliation of basic and diluted net income per share for the three months and nine months ended September 30, 2013 and 2012 is as follows (in thousands of U.S. dollars, except per share amounts):


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012

At September 30, 2013 and 2012, share based awards to purchase 140.5 thousand and 1,233.3 thousand common shares, respectively, were excluded from the calculation of diluted weighted average number of common shares and common share equivalents outstanding because their exercise prices were greater than the average market price of the common shares.

7. Noncontrolling Interests

During March 2013, the Company formed Lorenz Re Ltd. (Lorenz Re), a Bermuda domiciled special purpose insurer to provide additional capacity to the Company for a diversified portfolio of catastrophe reinsurance treaties over a multi-year period on a fully collateralized reinsurance basis. The original business was written by the Company and was ceded to Lorenz Re effective April 1, 2013.

In conjunction with the formation of Lorenz Re, the Company and third party investors each contributed 50% of Lorenz Re’s non-voting redeemable preferred share capital of approximately $75 million. On May 1, 2013, the Company sold $10.5 million of its original investment in Lorenz Re to third party investors. The Company did not record any gain or loss on the sale of this investment. Lorenz Re’s preferred shares are expected to be redeemed following the commutation of the portfolio back to the Company on or before June 1, 2016.

Lorenz Re is considered to be a variable interest entity. The Company has concluded that it is the primary beneficiary as it has the power to direct and has more than an insignificant economic interest in the activities of Lorenz Re. Lorenz Re is consolidated by the Company and all inter-company balances and transactions are eliminated. Net income and shareholders’ equity attributable to Lorenz Re’s third party investors are recorded in the Condensed Consolidated Financial Statements as noncontrolling interests.

At September 30, 2013, the total assets of Lorenz Re were $100.9 million, primarily consisting of cash and investments, and the total liabilities were $18.9 million, primarily consisting of unearned premiums and unpaid losses and loss expenses. The assets of Lorenz Re can only be used to settle the liabilities of Lorenz Re and there is no recourse to the Company for any liabilities of Lorenz Re.

The reconciliation of the beginning and ending balance of the noncontrolling interests in Lorenz Re for the nine months ended September 30, 2013 is as follows (in thousands of U.S. dollars):


	Total
	2013
Balance at January 1	$	—
Net income attributable to noncontrolling interests		5,296
Sale of shares to noncontrolling interests		47,193

8. Commitments and Contingencies

(a) Concentration of Credit Risk

Financing receivables

Included in the Company’s Other invested assets are certain notes receivable which meet the definition of financing receivables and are accounted for using the cost method of accounting. These notes receivable are collateralized by commercial or residential property. The Company utilizes a third party consultant to determine the initial investment criteria and to monitor the subsequent performance of the notes receivable. The process undertaken prior to the investment in these notes receivable includes an examination of the underlying collateral. The Company reviews its receivable positions on at least a quarterly basis using actual redemption experience. At September 30, 2013 and December 31, 2012, based on the latest available information, the Company recorded an allowance for credit losses related to these notes receivable of $2.7 million and $3.0 million, respectively.

The Company monitors the performance of the notes receivable based on the type of underlying collateral and by assigning a “performing” or a “non-performing” indicator of credit quality to each individual receivable. At September 30, 2013, the Company’s notes receivable of $33.3 million were all performing and were collateralized by residential property and commercial property of $25.5 million and $7.8 million, respectively. At December 31, 2012, the Company’s notes receivable of $46.7 million were all performing and were collateralized by residential property and commercial property of $31.3 million and $15.4 million, respectively.

The Company purchased $1.9 million and $29.0 million of financing receivables during the three months and nine months ended September 30, 2013, respectively. The Company purchased $0.2 million and $37.6 million of financing receivables during the three months and nine months ended September 30, 2012, respectively. There were no sales of financing receivables during the three months and nine months ended September 30, 2013 and 2012, however, the outstanding balances were reduced by settlements of the underlying debt.

(b) Employment Agreements

During the three months and nine months ended September 30, 2013, the Company recorded pre-tax charges of $2.4 million and $45.7 million, respectively, related to the expected costs of the restructuring, which were primarily related to the termination plans, within other operating expenses. The continuing salary and other employment benefit costs related to the affected employees will be expensed as the employee remains with the Company and provides service.

In connection with the restructuring, and included within the total expected costs of between $60 million and $70 million announced by the Company in April 2013, the Company expects to incur a charge of approximately $10 million related to certain real estate costs in the fourth quarter of 2013, with further real estate related charges totaling between $5 million and $10 million expected to be incurred in 2014.

(c) Legal Proceedings

There has been no significant change in legal proceedings at September 30, 2013 compared to December 31, 2012. See Note 17(e) to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

(d) Taxation

As part of the 2014 Budget proposals, the French government has proposed tax legislation changes. These proposals would temporarily increase the corporation income tax rate from 36% to 38% and could limit the deductibility of interest payments to non-French affiliates. These changes may be effective retroactively to January 1, 2013. These proposals have not been enacted into the French tax code and, therefore, may be modified during the French legislative process. It is expected that the 2014 Budget proposals, including any tax proposals, will be finalized and enacted into law in December 2013. The Company is in the process of monitoring and evaluating the impact of these developments on its operations. The Company may incur a charge in the fourth quarter of 2013 relating to these tax proposals, which may be material, when these proposed tax changes are finalized and enacted into the French tax code. The Company is not currently able to determine a reasonable estimate of the amount of the charge given the uncertainty that exists related to these proposals.

9. Credit Agreements

In the normal course of its operations, the Company enters into agreements with financial institutions to obtain unsecured and secured credit facilities. These facilities are used primarily for the issuance of letters of credit, although a portion of these facilities may also be used for liquidity purposes.

On April 18, 2013, the Company modified its existing three-year syndicated unsecured credit facility to reduce the available facility from $500 million to $50 million and reduce its access to a revolving line of credit from $375 million to $50 million. This facility expired on July 15, 2013 and was not renewed.

See Note 18 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for further information related to the credit facilities available to the Company.

10. Segment Information

The Company monitors the performance of its operations in three segments, Non-life, Life and Health and Corporate and Other as described in Note 20 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The Non-life segment is further divided into four sub-segments: North America, Global (Non-U.S.) P&C, Global Specialty and Catastrophe. Following the acquisition of Presidio on December 31, 2012, Presidio’s results are included in the Life and Health segment. Effective January 1, 2013, the Life segment is referred to as Life and Health to reflect the inclusion of Presidio’s results following its acquisition and the Global (Non-U.S.) Specialty sub-segment is referred to as Global Specialty.

Since the Company does not manage its assets by segment, net investment income is not allocated to the Non-life segment. However, because of the interest-sensitive nature of some of the Company’s Life and Health products, net investment income is considered in Management’s assessment of the profitability of the Life and Health segment. The following items are not considered in evaluating the results of the Non-life and Life and Health segments: net realized and unrealized investment gains and losses, interest expense, amortization of intangible assets, net foreign exchange gains and losses, income tax expense or benefit and interest in earnings and losses of equity investments. Segment results are shown before consideration of intercompany transactions.

Management measures results for the Non-life segment on the basis of the loss ratio, acquisition ratio, technical ratio, other operating expense ratio and combined ratio (all defined below). Management measures results for the Non-life sub-segments on the basis of the loss ratio, acquisition ratio and technical ratio. Management measures results for the Life and Health segment on the basis of the allocated underwriting result, which includes revenues from net premiums earned, other income or loss and allocated net investment income for Life and Health, and expenses from life policy benefits, acquisition costs and other operating expenses.

The following tables provide a summary of the segment results for the three months and nine months ended September 30, 2013 and 2012 (in millions of U.S. dollars, except ratios):

10. Subsequent Events

At September 30, 2013, the Company had an equity investment in Essent Group Ltd. (Essent), a non-public U.S. mortgage guaranty insurance company, which was recorded at cost of $36 million. Essent became a publicly traded company on October 30, 2013 and, as a result, from this date the Company will record its investment in Essent at fair value, which was approximately $105 million based on the closing market price on October 31, 2013. The Company will report this unrealized gain and any subsequent changes in the fair value of this investment in net realized and unrealized investment gains and losses in the Consolidated Statements of Operations.

ITEM 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Executive Overview

The Company is a leading global reinsurer, with a broadly diversified and balanced portfolio of traditional reinsurance risks and capital markets risks.

Successful risk management is the foundation of the Company’s value proposition, with diversification of risks at the core of its risk management strategy. The Company’s ability to succeed in the risk assumption and management business is dependent on its ability to accurately analyze and quantify risk, to understand volatility and how risks aggregate or correlate, and to establish the appropriate capital requirements and limits for the risks assumed. All risks, whether they are reinsurance related risks or capital market risks, are managed by the Company within an integrated framework of policies and processes to ensure the intelligent and consistent evaluation and valuation of risk, and to ultimately provide an appropriate return to shareholders. The Company’s Risk Management framework is discussed below and further in Risk Management in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

A discussion of the Company’s long-term objective and annualized growth in Diluted Tangible Book Value per Share plus dividends, the metric that Management uses to measure its success in achieving its long-term objective, are described below in Key Financial Measures.

Overview of the Results of Operations for the Three Months and Nine Months Ended September 30, 2013

The Company measures its performance in several ways. Among the performance measures accepted under U.S. GAAP is diluted net income or loss per share, a measure that focuses on the return provided to the Company’s common shareholders. Diluted net income or loss per share is obtained by dividing net income or loss attributable to PartnerRe Ltd. common shareholders by the weighted average number of common shares and common share equivalents outstanding. Net income or loss attributable to PartnerRe Ltd. common shareholders is defined as net income or loss less preferred dividends and loss on redemption of preferred shares. See the discussion of the non-GAAP performance measures that the Company uses (operating earnings or loss and Operating ROE) and the reconciliation of those non-GAAP performance measures to the most directly comparable GAAP measures in Key Financial Measures below.

The following key factors affected the year over year comparison of the Company’s results and are discussed in more detail in Review of Net Income below.

Large catastrophic and large loss events

Given the Company’s reinsurance operations are exposed to low frequency and high severity risk events, some of which are seasonal, results for certain periods may include unusually low loss experience, while results for other periods may include significant catastrophic losses. Consequently, the Company’s results for interim periods may be volatile from period to period and are not necessarily indicative of results for the full year. The results for the three months and nine months ended September 30, 2013 and 2012 demonstrate this volatility. During the three months ended September 30, 2013, the Company incurred losses of $55 million, net of retrocession and reinstatement premiums, related to the hailstorm that affected large parts of Germany in July 2013 (German Hailstorm). During the nine months ended September 30, 2013, the Company incurred losses of $156 million, net of retrocession and reinstatement premiums, related to the combined impact of the extensive flooding in Alberta, Canada (Alberta Floods) in June 2013, the German Hailstorm and the floods that impacted large areas of Central Europe in June 2013 (European Floods). The results for the three months and nine months ended September 30, 2012 included large losses of $85 million in the agriculture line of business of the Company’s North America sub-segment related to the severe drought conditions in the U.S. during 2012 (U.S. drought).

The following tables reflect the impact of large catastrophic losses related to the German Hailstorm in the three months ended September 30, 2013 and Alberta Floods, German Hailstorm and European Floods in the nine months ended September 30, 2013 on the Company’s technical result, pre-tax net income, loss ratio, technical ratio and combined ratio by segment and sub-segment for the three months and nine months ended September 30, 2013, and the large catastrophic losses by event for the nine months ended September 30, 2013 (in millions of U.S. dollars):

Volatility in capital markets

The results for the nine months ended September 30, 2013 and 2012 and for the three months ended September 30, 2012 were impacted by the volatility in the capital markets primarily as result of increases in risk-free interest rates during 2013 and narrowing spreads in 2012. The results for the three months ended September 30, 2013 were less impacted given the overall changes in interest rates, credit spreads and equity markets were more modest.

Restructuring charges

In April 2013, the Company announced the restructuring of its business support operations into a single integrated worldwide support platform and changes to the structure of its Global Non-life Operations. The restructuring includes involuntary and voluntary employee termination plans in certain jurisdictions (collectively, termination plans) and certain real estate related costs. Employees affected by the termination plans have varying leaving dates, largely through to mid-2014. The Company expects to incur a charge, totaling between $60 million and $70 million to be incurred primarily in 2013 with the remainder expected to be incurred in 2014. During the three months and nine months ended September 30, 2013, the Company recorded pre-tax charges of approximately $2 million and $46 million, respectively, related to the expected costs of the restructuring, which were primarily related to the termination plans, within other operating expenses. The continuing salary and other employment benefit costs related to the affected employees will be expensed as the employee remains with the Company and provides service.

Acquisition of Presidio

Effective December 31, 2012, the Company completed the acquisition of Presidio Reinsurance Group, Inc. (Presidio), a California-based U.S. specialty accident and health reinsurance and insurance writer. The Condensed Consolidated Statements of Operations and Cash Flows, and the Life and Health segment, include the results of Presidio from January 1, 2013.

Net income

Net income, net income attributable to noncontrolling interests, preferred dividends, loss on redemption of preferred shares, net income attributable to PartnerRe Ltd. common shareholders and diluted net income per share for the three months and nine months ended September 30, 2013 and 2012 were as follows (in millions of U.S. dollars, except per share data):


	For the three months ended September 30, 2013		For the three months ended September 30, 2012		For the nine months ended September 30, 2013		For the nine months ended September 30, 2012

Diluted net income per share attributable to PartnerRe Ltd. common shareholders	$	5.84	$	7.53	$	5.93	$	15.19

Three-month result

The decrease in net income of $149 million, from $487 million in the three months ended September 30, 2012 to $338 million in the same period of 2013 resulted primarily from:

•

a decrease of $241 million in pre-tax net realized and unrealized investment gains, mainly as a result of narrowing credit spreads in the three months ended September 30, 2012 compared to modest changes in interest rates, credit spreads and equity markets in the same period of 2013; partially offset by

•

an increase of $96 million in the Non-life underwriting result, which was mainly driven by an increase in combined favorable prior year and prior quarters’ loss development and a relatively lower level of catastrophic losses related to the German Hailstorm in the three months ended September 30, 2013 compared to large losses related to the U.S. drought in the same period of 2012.

The decrease in net income attributable to PartnerRe Ltd. common shareholders and diluted net income per share for the three months ended September 30, 2013 compared to the same period of 2012 was primarily due to the above factors. For diluted net income per share specifically, the decrease was partially offset by the accretive impact of a reduction in the diluted number of common shares and common share equivalents outstanding as a result of share repurchases.

Nine-month result

The decrease in net income of $625 million, from $1,023 million in the nine months ended September 30, 2012 to $398 million in the same period of 2013 resulted primarily from:

•

an increase of $748 million in pre-tax net realized and unrealized investment losses, mainly as a result of increases in the U.S. and European risk-free interest rates during 2013 compared to narrowing spreads and improvements in equity markets in 2012;

•

a decrease of $66 million in net investment income, driven by lower reinvestment rates; and

•

an increase of $54 million in other operating expenses included in Corporate and Other, driven by the charge related to the costs of the restructuring described above; partially offset by

•

a decrease of $144 million in income tax expense, resulting from a lower pre-tax net income in the nine months ended September 30, 2013 compared to the same period of 2012; and

•

an increase of $79 million in the Non-life underwriting result, which was mainly driven by an increase in favorable prior year loss development.

The decrease in net income attributable to PartnerRe Ltd. common shareholders and diluted net income per share for the nine months ended September 30, 2013 compared to the same period of 2012 was primarily due to the above factors. For diluted net income per share specifically, the decrease was partially offset by the accretive impact of a reduction in the diluted number of common shares and common share equivalents outstanding as a result of share repurchases.

The factors affecting the year over year comparison of the Company’s results are discussed below in Review of Net Income, Results by Segment and Financial Condition, Liquidity and Capital Resources, and may continue to affect our results of operations and financial condition in the future.

Key Financial Measures

In addition to the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Operations and Comprehensive Income, Management uses certain key measures to evaluate its financial performance and the overall growth in value generated for the Company’s common shareholders.

The Company’s long-term objective is to manage a portfolio of diversified risks that will create total shareholder value. The Company measures its success in achieving its long-term objective by targeting a return, which is variable and can be adjusted by Management, in excess of a referenced risk-free rate over the reinsurance cycle. The return, which is currently targeted at 700 basis points in excess of the referenced risk-free rate, is calculated using compound annual growth in diluted tangible book value per common share and common share equivalents outstanding plus dividends per common share (annualized growth in Diluted Tangible Book Value per Share plus dividends). Management uses annualized growth in Diluted Tangible Book Value per Share plus dividends as its prime measure of long-term financial performance and believes this measure aligns the Company’s stated long-term objective with the measure most investors use to evaluate total shareholder value creation given that it focuses on the tangible value of total shareholder returns, excluding the impact of goodwill and intangibles. Given the Company’s profitability in any particular quarterly or annual period can be significantly affected by the level of large catastrophic losses, Management assesses this long-term objective over the reinsurance cycle as the Company’s performance during any particular quarterly or annual period is not necessarily indicative of its performance over the longer-term reinsurance cycle.

While annualized growth in Diluted Tangible Book Value per Share plus dividends is the Company’s prime financial measure, management also uses other key financial measures to monitor performance as set forth below, together with definitions of their calculations, at September 30, 2013 and December 31, 2012 and for the three months and nine months ended September 30, 2013 and 2012:


	September 30, 2013			December 31, 2012
Diluted tangible book value per common share and common share equivalents outstanding⁽¹⁾	$	94.86		$	90.86
Annualized growth in diluted tangible book value per common share and common share equivalents outstanding plus dividends⁽²⁾		8.7	%


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012
Operating earnings attributable to PartnerRe Ltd. common shareholders (in millions of U.S. dollars)⁽³⁾	$	311		$	244		$	564		$	568
Annualized operating return on beginning diluted book value per common share and common share equivalents outstanding⁽⁴⁾		22.6	%		18.4	%		13.0	%		13.9	%
Combined ratio⁽⁵⁾		74.9	%		80.7	%		84.2	%		85.1	%

(1)

Diluted tangible book value per common share and common share equivalents outstanding (Diluted Tangible Book Value per Share) is calculated using common shareholders’ equity attributable to PartnerRe Ltd. (total shareholders’ equity less noncontrolling interests and the aggregate liquidation value of preferred shares) less goodwill and intangible assets, net of tax, divided by the weighted average number of common shares and common share equivalents outstanding (assuming exercise of all stock-based awards and other dilutive securities). The presentation of Diluted Tangible Book Value per Share is a non-GAAP financial measure within the meaning of Regulation G (see Comment on Non-GAAP Measures below) and is reconciled to the most directly comparable GAAP financial measure below.

(2)

Annualized growth in diluted tangible book value per common share and common share equivalents outstanding plus dividends (annualized growth in Diluted Tangible Book Value per Share plus dividends) is calculated using Diluted Tangible Book Value per Share plus dividends per common share divided by Diluted Tangible Book Value per Share at the beginning of the year and annualizing. The presentation of annualized growth in Diluted Tangible Book Value per Share plus dividends is a non-GAAP financial measure within the meaning of Regulation G (see Comment on Non-GAAP Measures below) and is reconciled to the most directly comparable GAAP financial measure below.

(3)

Operating earnings attributable to PartnerRe Ltd. common shareholders (operating earnings) is calculated as net income or loss available to PartnerRe Ltd. common shareholders excluding net realized and unrealized gains or losses on investments, net of tax (except where the Company has made a strategic investment in an insurance or reinsurance related investee), net foreign exchange gains or losses, net of tax, loss on redemption of preferred shares and the interest in earnings or losses of equity investments, net of tax (except where the Company has made a strategic investment in an insurance or reinsurance related investee and where the Company does not control the investee’s activities), and is calculated after preferred dividends. The presentation of operating earnings or loss is a non-GAAP financial measure within the meaning of Regulation G (see Comment on Non-GAAP Measures below) and is reconciled to the most directly comparable GAAP financial measure below.

(4)

Annualized operating return on beginning diluted book value per common share and common share equivalents outstanding (Operating ROE) is calculated using annualized operating earnings or loss, as defined above, per diluted common share and common share equivalents outstanding, divided by diluted book value per common share and common share equivalents outstanding as of the beginning of the year, as defined above. The presentation of Operating ROE is a non-GAAP financial measure within the meaning of Regulation G (see Comment on Non-GAAP Measures below) and is reconciled to the most directly comparable GAAP financial measure below.

(5)

The combined ratio of the Non-life segment is calculated as the sum of the technical ratio (losses and loss expenses and acquisition costs divided by net premiums earned) and the other operating expense ratio (other operating expenses divided by net premiums earned).

Diluted Tangible Book Value per Share: Diluted Tangible Book Value per Share focuses on the underlying fundamentals of the Company’s financial position and performance without the impact of goodwill or intangible assets. As discussed above, the Company uses this measure as the basis for its prime measure of long-term shareholder value creation, growth in Diluted Tangible Book Value per Share plus dividends. Management believes that Diluted Tangible Book Value per Share aligns the Company’s stated long-term objectives with the measure most investors use to evaluate total shareholder value creation and that it focuses on the tangible value of shareholder returns, excluding the impact of goodwill and intangibles. Diluted Tangible Book Value per Share is impacted by the Company’s net income or loss, capital resources management and external factors such as foreign exchange, interest rates, credit spreads and equity markets, which can drive changes in realized and unrealized gains or losses on its investment portfolio.

The following table shows the Diluted Tangible Book Value per Share at September 30, 2013 and December 31, 2012 and the calculation of the annualized growth in Diluted Tangible Book Value per Share plus dividends for the nine months ended September 30, 2013. As described above, this metric is a long-term performance measure, however, the below table shows the annualized total shareholder value creation for the current period in order for the shareholders to monitor its performance.


	September 30, 2013			December 31, 2012
Diluted tangible book value per common share and share equivalents outstanding	$	94.86		$	90.86
Dividends per common share for the nine months ended September 30, 2013		1.92

Diluted tangible book value per share plus dividends	$	96.78
Annualized growth in diluted tangible book value per share plus dividends		8.7	%

The Company’s Diluted Tangible Book Value per Share increased by 4.4% to $94.86 at September 30, 2013 from $90.86 at December 31, 2012 primarily due to net income attributable to PartnerRe Ltd. and the accretive impact of the share repurchases, which were partially offset by dividends on the common and preferred shares. The annualized growth in Diluted Tangible Book Value per Share plus dividends was 8.7% for the nine months ended September 30, 2013 and was driven by the same factors as the Diluted Tangible Book Value per Share.

Over the past five years, since September 30, 2008, the Company has generated a compound annualized growth in Diluted Tangible Book Value per Share plus dividends in excess of 13%.

The presentation of Diluted Tangible Book Value per Share is a non-GAAP financial measure within the meaning of Regulation G and should be considered in addition to, and not as a substitute for, measures of financial performance prepared in accordance with GAAP (see Comment on Non-GAAP Measures). The table below provides a reconciliation of Diluted Tangible Book Value per Share to the most directly comparable GAAP financial measure, diluted book value per common share and common share equivalents outstanding, at September 30, 2013 and December 31, 2012 (in millions of U.S. dollars):


	September 30, 2013		December 31, 2012
Diluted book value per common share and common share equivalents outstanding⁽¹⁾	$	105.53	$	100.84

Diluted tangible book value per share	$	94.86	$	90.86

(1)

Diluted book value per common share and common share equivalents outstanding (Diluted Book Value per Share) is calculated using common shareholders’ equity attributable to PartnerRe Ltd. (total shareholders’ equity less noncontrolling interests and the aggregate liquidation value of preferred shares) divided by the weighted average number of common shares and common share equivalents outstanding (assuming exercise of all stock-based awards and other dilutive securities).

Operating earnings attributable to PartnerRe Ltd. common shareholders (operating earnings): Management uses operating earnings to measure its financial performance as this measure focuses on the underlying fundamentals of the Company’s operations by excluding net realized and unrealized gains or losses on investments (except where the Company has made a strategic investment in an investee whose operations are insurance or reinsurance related and where the Company does not control the investee’s activities), net foreign exchange gains or losses, loss on redemption of preferred shares and certain interest in earnings or losses of equity investments (except where the Company has made a strategic investment in an investee whose operations are insurance or reinsurance related and where the Company does not control the investee’s activities). Net realized and unrealized gains or losses on investments in any particular period are not indicative of the performance of, and distort trends in, the Company’s business as they predominantly result from general economic and financial market conditions, and the timing of realized gains or losses on investments is largely opportunistic. Net foreign exchange gains or losses are not indicative of the performance of, and distort trends in, the Company’s business as they predominantly result from general economic and foreign exchange market conditions. Loss on the redemption of preferred shares is not indicative of the performance of, and distorts trends in, the Company’s business as it resulted from general economic and financial market conditions, and the timing of the loss on redemption was largely opportunistic. Interest in earnings or losses of equity investments are also not indicative of the performance of, or trends in, the Company’s business where the investee’s operations are not insurance or reinsurance related and where the Company does not control the investee companies’ activities. Management believes that the use of operating earnings or loss enables investors and other users of the Company’s financial information to analyze its performance in a manner similar to how Management analyzes performance. Management also believes that this measure follows industry practice and, therefore, allows the users of financial information to compare the Company’s performance with its industry peer group, and that the equity analysts and certain rating agencies which follow the Company, and the insurance industry as a whole, generally exclude these items from their analyses for the same reasons.

Operating earnings increased by $67 million, from $244 million in the three months ended September 30, 2012 to $311 million in the same period of 2013. The increase was primarily due to an improvement in the Non-life underwriting result, driven by a higher level of favorable prior year and prior quarters’ loss development, which was partially offset by an increase in the income tax expense associated with the higher level of pre-tax operating earnings.

Operating earnings decreased by $4 million, from $568 million in the nine months ended September 30, 2012 to $564 million in the same period of 2013. The decrease was primarily due to a decline in net investment income driven by lower reinvestment rates, and higher operating expenses driven by a charge related to the restructuring. These decreases were partially offset by an increase in Non-life and Life underwriting results, driven by a higher level of favorable prior year loss development, and a decrease in the income tax expense associated with the lower level of pre-tax operating earnings.

The other lesser factors contributing to the increases or decreases in operating earnings in the three months and nine months ended September 30, 2013 compared to the same periods of 2012 are further described in Review of Net Income below.

The presentation of operating earnings attributable to PartnerRe Ltd. common shareholders is a non-GAAP financial measure within the meaning of Regulation G and should be considered in addition to, and not as a substitute for, measures of financial performance prepared in accordance with GAAP (see Comment on Non-GAAP Measures). The table below provides a reconciliation of operating earnings to the most directly comparable GAAP financial measure for the three months and nine months ended September 30, 2013 and 2012 (in millions of U.S. dollars):

Operating ROE: Management uses annualized Operating ROE as a measure of profitability that focuses on the return to common shareholders on an annual basis. To support the Company’s growth objectives, most economic decisions, including capital attribution and underwriting pricing decisions, incorporate an Operating ROE impact analysis. For the purpose of that analysis, an appropriate amount of capital (equity) is attributed to each transaction for determining the transaction’s priced return on attributed capital. Subject to an adequate return for the risk level as well as other factors, such as the contribution of each risk to the overall risk level and risk diversification, capital is attributed to the transactions generating the highest priced return on deployed capital. Management’s challenge consists of (i) attributing an appropriate amount of capital to each transaction based on the risk created by the transaction, (ii) properly estimating the Company’s overall risk level and the impact of each transaction on the overall risk level, (iii) assessing the diversification benefit, if any, of each transaction, and (iv) deploying available capital. The risk for the Company lies in mis-estimating any one of these factors, which are critical in calculating a meaningful priced return on deployed capital, and entering into transactions that do not contribute to the Company’s growth objectives. The Company’s Operating ROE’s for quarterly periods are annualized.

Annualized Operating ROE increased from 18.4% in the three months ended September 30, 2012 to 22.6% in the same period of 2013. The increase in annualized Operating ROE was primarily due to the increase in operating earnings in the three months ended September 30, 2013 compared to the same period of 2012, as described above, and was partially offset by a higher beginning diluted book value per share at January 1, 2013 compared to January 1, 2012. The factors contributing to increases or decreases in operating earnings are described further in Review of Net Income below.

Annualized Operating ROE decreased modestly from 13.9% in the nine months ended September 30, 2012 to 13.0% in the same period of 2013. The decrease in annualized Operating ROE was primarily due to the modest decline in operating earnings in the nine months ended September 30, 2013 compared to the same period of 2012, as described above, and also due to a higher beginning diluted book value per share at January 1, 2013 compared to January 1, 2012. The factors contributing to increases or decreases in operating earnings are described further in Review of Net Income below.

The presentation of Operating ROE is a non-GAAP financial measure within the meaning of Regulation G and should be considered in addition to, and not as a substitute for, measures of financial performance prepared in accordance with GAAP (see Comment on Non-GAAP Measures). The table below provides a reconciliation of Operating ROE to the most directly comparable GAAP financial measure for the three months and nine months ended September 30, 2013 and 2012:


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012

Annualized operating return on beginning diluted book value per common share		22.6	%		18.4	%		13.0	%		13.9	%

Combined ratio: The combined ratio is used industry-wide as a measure of underwriting profitability for Non-life business. A combined ratio under 100% indicates underwriting profitability, as the total losses and loss expenses, acquisition costs and other operating expenses are less than the premiums earned on that business. While an important metric of underwriting profitability, the combined ratio does not reflect all components of profitability, as it does not recognize the impact of investment income earned on premiums between the time premiums are received and the time loss payments are ultimately made to clients. The key challenges in managing the combined ratio metric consist of (i) focusing on underwriting profitable business even in the weaker part of the reinsurance cycle, as opposed to growing the book of business at the cost of profitability, (ii) diversifying the portfolio to achieve a good balance of business, with the expectation that underwriting losses in certain lines or markets may potentially be offset by underwriting profits in other lines or markets, and (iii) maintaining control over expenses.

The Non-life combined ratio decreased by 5.8 points, from 80.7% in the three months ended September 30, 2012 to 74.9% in the same period of 2013. The decrease in the combined ratio for the three months ended September 30, 2013 compared to the same period of 2012 primarily reflected the increase in net favorable prior year loss development and a lower level of large and catastrophic losses.

The Non-life combined ratio decreased by 0.9 points, from 85.1% in the nine months ended September 30, 2012 to 84.2% in the same period of 2013. The modest decrease in the combined ratio in the nine months ended September 30, 2013 compared to the same period of 2012 was primarily due to the increase in net favorable prior year loss development and a lower other operating expense ratio driven by an increased level of net premiums earned, which was partially offset by a higher level of large catastrophic losses and large losses. The impact on the combined ratio of the catastrophic events for each period is analyzed above.

The other lesser factors contributing to increases or decreases in the combined ratio are described further in Review of Net Income below.

The Company uses the combined ratio to measure its overall underwriting profitability for its Non-life segment as a whole. Given the Company does not allocate operating expenses to its Non-life sub-segments, Management measures the underwriting profitability of the Non-life sub-segments by using the technical result and technical ratio as described in Results by Segment below.

Other Key Financial Measures

In addition to using the annualized growth in Diluted Tangible Book Value per Share plus dividends as the Company’s prime financial long-term measure, and diluted tangible book value per common share and common share equivalents outstanding (Diluted Tangible Book Value per Share) as the basis for this measure, the Company uses other metrics to monitor its financial performance and to measure total shareholder value. Other such metrics used by Management include, but are not limited to, diluted book value per common share and common share equivalents outstanding (Diluted Book Value per Share) and Diluted Tangible Book Value per Share plus the discount in Non-life loss reserves per common share and common share equivalents outstanding (Diluted Tangible Book Value plus the discount in Non-life reserves). Diluted Book Value per Share is a similar metric to Diluted Tangible Book Value per Share, except that it includes the impact on book value of goodwill and intangible assets. Diluted Tangible Book Value plus the discount in Non-life loss reserves is a shorter-term metric that adjusts the Company’s Diluted Tangible Book Value per Share for the impact that changes in interest rates have on the time value of money that is embedded in the Company’s Non-life loss reserves.

Comment on Non-GAAP Measures

Throughout this filing, the Company’s results of operations have been presented in the way that Management believes will be the most meaningful and useful to investors, analysts, rating agencies and others who use financial information in evaluating the performance of the Company. This presentation includes the use of Diluted Tangible Book Value per Share, Diluted Tangible Book Value per Share plus dividends, operating earnings or loss and Operating ROE that are not calculated under standards or rules that comprise U.S. GAAP. These measures are referred to as non-GAAP financial measures within the meaning of Regulation G. Management believes that these non-GAAP financial measures are important to investors, analysts, rating agencies and others who use the Company’s financial information and will help provide a consistent basis for comparison between years and for comparison with the Company’s peer group, although non-GAAP measures may be defined or calculated differently by other companies. Investors should consider these non-GAAP measures in addition to, and not as a substitute for, measures of financial performance prepared in accordance with GAAP. A reconciliation of these measures to the most directly comparable U.S. GAAP financial measures, diluted book value per share, net income or loss and return on beginning common shareholders’ equity calculated with net income or loss attributable to common shareholders, is presented above.

Risk Management

In the reinsurance industry, the core of the business model is the assumption and management of risk. A key challenge is to create economic value through the intelligent and optimal assumption and management of reinsurance and capital markets and investment risks while limiting and mitigating those risks that can destroy tangible as well as intangible value, those risks for which the organization is not sufficiently compensated, and those risks that could threaten the ability of the Company to achieve its objectives. While many companies start with a return goal and then attempt to shed risks that may derail that goal, the Company starts with a capital-based risk appetite and then looks for risks that meet its return targets within that framework. Management believes that this construct allows the Company to balance the cedants’ need for certainty of claims payment with the shareholders’ need for an adequate return.

All business decisions entail a risk/return trade-off, and these decisions are applicable to the Company’s risks. In the context of assumed business risks, this requires an accurate evaluation of risks to be assumed, and a determination of the appropriate economic returns required as fair compensation for such risks.

The Company’s results are primarily determined by how well the Company understands, prices and manages assumed risk. Management also believes that every organization faces numerous risks that could threaten the successful achievement of a company’s goals and objectives. These include choice of strategy and markets, economic and business cycles, competition, changes in regulation, data quality and security, fraud, business interruption and management continuity; all factors which can be viewed as either strategic, financial, or operational risks that are common to any industry. See Risk Factors in Item 1A of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. For additional information related to the Company’s risk management approach, see Business—Risk Management in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Assumed Risks

Central to the Company’s assumed risk framework is its risk appetite. The Company’s risk appetite is a statement of how much and how often the Company will tolerate operating losses and economic losses during an annual period. The Company’s risk appetite is expressed as the maximum operating loss and the maximum economic loss that the Board is willing to incur. The Company’s risk appetite is approved by the Board on an annual basis.

The Company establishes key risk limits for any risk source deemed by Management to have the potential to cause operating losses or economic losses greater than the Company’s risk appetite. The Risk and Finance Committee of the Board (Risk and Finance Committee) approves the key risk limits. Executive and Business Unit Management may set additional specific and aggregate risk limits within the key risk limits approved by the Risk and Finance Committee. The actual level of risk is dependent on current market conditions and the need for balance in the Company’s portfolio of risks. On a periodic basis, Management reviews and reports to the Risk and Finance Committee the actual limits deployed against the approved limits.

Management established key risk limits that are approved by the Risk and Finance Committee for eight risk sources at December 31, 2012. For a detailed discussion of these eight risk sources see Business—Risk Management in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

During the nine months ended September 30, 2013, the Company added agriculture risk to its Risk Management framework, as the ninth key risk. The risk limit for agriculture risk was approved by the Risk and Finance Committee. The following discussion updates Risk Management in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Agriculture Risk

The Company defines this risk as the risk that losses from multi-peril crop insurance materially exceed the net premiums that are received to cover such risks, which may result in operating and economic losses to the Company. Multi-peril crop underwriting losses of the magnitude that have the potential to exceed the Company’s risk appetite are associated with the systemic impacts of severe weather events, particularly drought or flooding, over a large geographic area. Localized events such as convective thunderstorms or hail, while potentially devastating, are unlikely to have the large geographic footprint necessary to create material losses exceeding the net premiums collected.

Multi-peril crop risk is managed through geographic diversification both within individual countries and across countries. This is accomplished through the allocation and tracking of capacity across exposure zones (defined as individual countries) and is accompanied by regular extreme event modeling, and a combination of quantitative and qualitative analysis.

The Company utilizes probable maximum loss estimates, net of retrocession, to manage its exposures. The limit approved measure is aggregated by contract within an exposure zone to establish the total exposures. Actual exposures deployed and estimated probable maximum losses in a specific zone will vary from period to period depending on Management’s assessment of current market conditions, the results from exposure modeling, and other analysis.

The following table shows the limits approved by the Risk and Finance Committee and the actual limits deployed at September 30, 2013 and December 31, 2012:

With respect to the Natural Catastrophe Risk, see Natural Catastrophe Probable Maximum Loss (PML) below for a discussion of the Company’s estimated exposures for selected peak industry natural catastrophe perils at July 1, 2013. For a discussion of operational and financial risks, other underwriting risks and exposure controls, retrocessions and claims, see Business—Risk Management in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Natural Catastrophe Probable Maximum Loss (PML)

The following discussion of the Company’s natural catastrophe probable maximum loss (PML) information contains forward-looking statements based upon assumptions and expectations concerning the potential effect of future events that are subject to uncertainties. See Item 1A of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a list of the Company’s risk factors. Any of these risk factors could result in actual losses that are materially different from the Company’s PML estimates below.

Natural catastrophe risk is a source of significant aggregate exposure for the Company and is managed by setting risk appetite and limits, as discussed above. The peril zones in the disclosure below are major peril zones for the industry. The Company has exposures in other peril zones that can potentially generate losses greater than the PML estimates below. The Company’s PMLs represent an estimate of loss for a single event for a given return period. The table below discloses the Company’s 1-in-250 and 1-in-500 year return period estimated loss for a single occurrence of a natural catastrophe event in a one-year period. For risk management purposes, the Company focuses more on the 1-in-250 PML estimate for wind perils and the 1-in-500 PML for earthquake perils.

The PML estimates below include all significant exposure from our Non-life and Life and Health business operations. This includes coverage for property, marine, energy, aviation, engineering, workers’ compensation and mortality. In addition, the PML estimates include the contractual limits of insurance-linked securities. The PML estimates do not include casualty coverage that could be exposed as a result of a catastrophic event. In addition, they do not include estimates for contingent losses to insureds that are not directly impacted by the event (e.g. loss of earnings due to disruption in supply lines).

For additional information related to the Company’s natural catastrophe PML information and definitions, see Business—Natural Catastrophe Probable Maximum Loss (PML) in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

The table below shows the Company’s single occurrence estimated net PML exposures (pre-tax and net of retrocession and reinstatement premiums) for certain selected peak industry natural catastrophe perils at July 1, 2013 (in millions of U.S. dollars):


		Single Occurrence Estimated Net Exposure
Zone	Peril	1-in-250 year PML		1-in-500 year PML (Earthquake Perils Only)
U.S. Southeast	Hurricane	$	1,054		—
U.S. Northeast	Hurricane		1,121		—
U.S. Gulf Coast	Hurricane		1,025		—
Caribbean	Hurricane		276		—
Europe	Windstorm		872		—
Japan	Typhoon		124		—
California	Earthquake		575	$	679
British Columbia	Earthquake		305		513
Japan	Earthquake		435		457
Australia	Earthquake		418		552
New Zealand	Earthquake		250		272

The Company estimates that the incremental loss at the 1-in-250 year return period from a U.S. hurricane impacting more than one of the three hurricane risk zones in the U.S. would be 20% higher than the PML of the largest zone impacted. In addition, there is the potential for a hurricane to impact the Caribbean peril zone and one or more U.S. hurricane peril zones.

Critical Accounting Policies and Estimates

Critical Accounting Policies and Estimates of the Company at September 30, 2013 have not changed materially compared to December 31, 2012. The following discussion updates specific information related to the Company’s estimates for losses and loss expenses and life policy benefits and valuation of investments and funds held – directly managed, including certain derivative financial instruments. See Critical Accounting Policies and Estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of the Company’s other critical accounting policies which are not specifically updated in this report given they have not changed materially compared to December 31, 2012.

Losses and Loss Expenses and Life Policy Benefits

Losses and Loss Expenses

Because a significant amount of time can elapse between the assumption of risk, occurrence of a loss event, the reporting of the event to an insurance company (the primary company or the cedant), the subsequent reporting to the reinsurance company (the reinsurer) and the ultimate payment of the claim on the loss event by the reinsurer, the Company’s liability for unpaid losses and loss expenses (loss reserves) is based largely upon estimates. The Company categorizes loss reserves into three types of reserves: reported outstanding loss reserves (case reserves), additional case reserves (ACRs) and incurred but not reported (IBNR) reserves. The Company updates its estimates for each of the aforementioned categories on a quarterly basis using information received from its cedants. The Company also estimates the future unallocated loss adjustment expenses (ULAE) associated with the loss reserves and these form part of the Company’s loss adjustment expense reserves. The Company’s Non-life loss reserves for each category and sub-segment are reported in the table included later in this section.

The amount of time that elapses before a claim is reported to the cedant and then subsequently reported to the reinsurer is commonly referred to in the industry as the reporting tail. For all lines, the Company’s objective is to estimate ultimate losses and loss expenses. Total loss reserves are then calculated by subtracting losses paid. Similarly, IBNR reserves are calculated by subtraction of case reserves and ACRs from total loss reserves.

The Company analyzes its ultimate losses and loss expenses after consideration of the loss experience of various reserving cells. The Company assigns treaties to reserving cells and allocates losses from the treaty to the reserving cell. The reserving cells are selected in order to ensure that the underlying treaties have homogeneous loss development characteristics (e.g., reporting tail) but are large enough to make estimation of trends credible. The selection of reserving cells is reviewed annually and changes over time as the business of the Company evolves. For each reserving cell, the Company’s estimates of loss reserves are reached after a review of the results of several commonly accepted actuarial projection methodologies. In selecting its best estimate, the Company considers the appropriateness of each methodology to the individual circumstances of the reserving cell and underwriting year for which the projection is made.

See Critical Accounting Policies and Estimates—Losses and Loss Expenses and Life Policy Benefits in Item 7 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information on the reserving methodologies employed by the Company, the principal reserving methods used for the reserving lines, the principal parameter assumptions underlying the methods and the main underlying factors upon which the estimates of reserving parameters are predicated.

The Company’s best estimate of total loss reserves is typically in excess of the midpoint of the actuarial ultimate liability estimate. The Company believes that there is potentially significant risk in estimating loss reserves for long-tail lines of business and for immature underwriting years that may not be adequately captured through traditional actuarial projection methodologies as these methodologies usually rely heavily on projections of prior year trends into the future. In selecting its best estimate of future liabilities, the Company considers both the results of actuarial point estimates of loss reserves as well as the potential variability of these estimates as captured by a reasonable range of actuarial liability estimates. The selected best estimates of reserves are always within the reasonable range of estimates indicated by the Company’s actuaries.

During the three months and nine months ended September 30, 2013 and 2012, the Company reviewed its estimate for prior year losses for the Non-life segment (defined below in Results by Segment) and, in light of developing data, adjusted its ultimate loss ratios for prior accident years. The following table summarizes the net prior year favorable loss development for each sub-segment of the Company’s Non-life segment for the three months and nine months ended September 30, 2013 and 2012 (in millions of U.S. dollars):


	For the three months ended September 30, 2013		For the three months ended September 30, 2012		For the nine months ended September 30, 2013		For the nine months ended September 30, 2012
Net Non-life prior year favorable loss development:
North America	$	94	$	67	$	155	$	167

Catastrophe		29		3		96		22

Total net Non-life prior year favorable loss development	$	238	$	189	$	548	$	468

The net Non-life prior year favorable loss development for the three months and nine months ended September 30, 2013 and 2012 was driven by the following factors (in millions of U.S. dollars):


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012

Total net Non-life prior year favorable loss development	$	238		$	189		$	548		$	468

(1)

Net prior year loss development due to changes in premiums includes, but it is not limited to, the impact to prior years’ reserves associated with (increases) decreases in the estimated or actual premium exposure reported by cedants.

(2)

Net prior year loss development due to all other factors includes, but is not limited to, loss experience, changes in assumptions and changes in methodology.

For a discussion of net prior year favorable loss development by Non-life sub-segment, see Results by Segment below. See Critical Accounting Policies and Estimates—Losses and Loss Expenses and Life Policy Benefits in Item 7 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information by reserving lines.

The following table shows the gross reserves reported by cedants (case reserves), those estimated by the Company (ACRs and IBNR reserves) and the total gross, ceded and net loss reserves recorded at September 30, 2013 for each Non-life sub-segment (in millions of U.S. dollars):


	Case reserves		ACRs		IBNR reserves		Total gross loss reserves recorded		Ceded loss reserves			Total net loss reserves recorded
North America	$	971	$	147	$	2,280	$	3,398	$	(21	)	$	3,377
Global (Non-U.S.) P&C		1,317		10		1,098		2,425		(19	)		2,406
Global Specialty		1,997		53		1,929		3,979		(196	)		3,783
Catastrophe		427		192		144		763		(50	)		713

Total Non-life reserves	$	4,712	$	402	$	5,451	$	10,565	$	(286	)	$	10,279

The net loss reserves represent the Company’s best estimate of future losses and loss expense amounts based on the information available at September 30, 2013. Loss reserves rely upon estimates involving actuarial and statistical projections at a given time that reflect the Company’s expectations of the costs of the ultimate settlement and administration of claims. Estimates of ultimate liabilities are contingent on many future events and the eventual outcome of these events may be different from the assumptions underlying the reserve estimates. These estimates are continually reviewed and the ultimate liability may be in excess of, or less than, the amounts provided, for which any adjustments will be reflected in the period in which the need for an adjustment is determined.

The Company’s best estimates are point estimates within a reasonable range of actuarial liability estimates. These ranges are developed using stochastic simulations and techniques and provide an indication as to the degree of variability of the loss reserves. The Company interprets the ranges produced by these techniques as confidence intervals around the point estimates for each Non-life sub-segment. However, due to the inherent volatility in the business written by the Company, there can be no assurance that the final settlement of the loss reserves will fall within these ranges.

The point estimates related to net loss reserves recorded by the Company and the range of actuarial estimates at September 30, 2013 were as follows for each Non-life sub-segment (in millions of U.S. dollars):


	Recorded Point Estimate		High		Low
Net Non-life sub-segment loss reserves:
North America	$	3,377	$	3,554	$	2,680
Global (Non-U.S.) P&C		2,406		2,533		2,064
Global Specialty		3,783		3,914		3,297
Catastrophe		713		723		570

It is not appropriate to add together the ranges of each sub-segment in an effort to determine a high and low range around the Company’s total Non-life carried loss reserves.

Of the Company’s $10,279 million of net Non-life loss reserves at September 30, 2013, net loss reserves for accident years 2005 and prior of $749 million are guaranteed by Colisée Re, pursuant to the Reserve Agreement. The Company is not subject to any loss reserve variability associated with the guaranteed reserves. See Business — Reserves in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of the Reserve Agreement.

A significant amount of judgment was used to estimate the range of potential losses related to the earthquakes that occurred in New Zealand in September 2010, February 2011 and June 2011 (the 2010 and the February and June 2011 New Zealand Earthquakes) and the Japan Earthquake (collectively, 2011 catastrophic events) and there remains a considerable degree of uncertainty related to the range of possible ultimate losses. These risks and uncertainties include the ongoing cedant revisions of loss estimates for each of these events, the degree to which inflation impacts construction materials required to rebuild affected properties, the characteristics of the Company’s program participation for certain affected cedants and potentially affected cedants, and the expected length of the claims settlement period for 2011 catastrophic events. In addition, there is additional complexity related to the 2010 and the February and June 2011 New Zealand Earthquakes given multiple earthquakes occurred in the same region in a relatively short time period, resulting in cedants continuing to revise their allocation of losses between the various events impacting different treaties, under which the Company may provide different amounts of coverage. Loss estimates arising from earthquakes are inherently more uncertain than those from other catastrophic events and the Company believes there remains a high degree of uncertainty related to its loss estimates for the 2011 catastrophic events, and the ultimate losses arising from these events may be materially in excess of, or less than, the amounts provided for in the Consolidated Balance Sheet at September 30, 2013.

Based upon information currently available and the estimated range of potential ultimate liabilities, the Company believes that unpaid loss and loss expense reserves contemplate a reasonable provision for exposure related to the 2011 catastrophic events. In addition to the sum of the point estimates recorded for each of the 2011 catastrophic events, at December 31, 2011 the Company recorded additional gross reserves of $50 million (net reserves of $48 million after the impact of retrocession), specifically related to these events within its Catastrophe sub-segment. The additional gross reserves recorded were in consideration of the number of events,

the complexity of certain events and the continuing uncertainties in estimating the ultimate losses for these events in the aggregate. The Company continues to evaluate the additional gross reserves that were recorded as part of its periodic reserving process and changes to the amounts recorded may either result in: i) the reallocation of some or all of the additional reserves to one or more of the 2011 catastrophic events; or ii) the release of some or all of the additional reserves to net income in future periods; or iii) an increase in additional reserves recorded. During the three months and nine months ended September 30, 2013, the Company reduced the additional gross reserves by $nil and $10 million, respectively, based on updated information from cedants, while still remaining cautious due to the uncertainties related to the specific factors regarding the 2011 catastrophic events.

Life Policy Benefits

Policy benefits for life and annuity contracts relate to the business in the Company’s Life and Health segment, which predominantly includes reinsurance of longevity, subdivided into standard and non-standard annuities, and mortality business, which includes death and disability covers (with various riders) primarily written in Continental Europe, term assurance and critical illness (TCI) primarily written in the United Kingdom and Ireland, and guaranteed minimum death benefit (GMDB) business primarily written in Continental Europe. Effective December 31, 2012, following the acquisition of Presidio, the Company writes specialty accident and health business, predominantly in the U.S. Presidio’s primary lines of business include Health Maintenance Organizations (HMO) reinsurance, medical reinsurance and provider and employer excess of loss programs.

The Company categorizes life reserves into three types of reserves: reported outstanding loss reserves (case reserves), IBNR reserves and reserves for future policy benefits. Such liabilities are established based on methods and underlying assumptions in accordance with U.S. GAAP and applicable actuarial standards. Principal assumptions used in the establishment of reserves for future policy benefits have been determined based upon information reported by ceding companies, supplemented by the Company’s actuarial estimates of mortality, critical illness, persistency and future investment income, with appropriate provision to reflect uncertainty. Case reserves, IBNR reserves and reserves for future policy benefits are generally calculated at the treaty level. The Company updates its estimates for each of the aforementioned categories on a periodic basis using information received from its cedants.

The Company’s reserving practices begin with the categorization of the contracts written as short duration, long duration, or universal life business for U.S. GAAP reserving purposes. This categorization determines the Company’s reserving methodology. See Critical Accounting Policies and Estimates—Losses and Loss Expenses and Life Policy Benefits—Life Policy Benefits in Item 7 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information on the reserving methodologies employed by the Company for its longevity, mortality and accident and health lines.

The following table provides the Company’s gross and net policy benefits for life and annuity contracts by reserving line at September 30, 2013 (in millions of U.S. dollars):


	Case reserves		IBNR reserves		Reserves for future policy benefits		Total gross Life and Health reserves recorded		Ceded reserves			Total net Life and Health reserves recorded

Valuation of Investments and Funds Held – Directly Managed, including certain Derivative Financial Instruments

The Company defines fair value as the price received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company measures the fair value of its financial instruments according to a fair value hierarchy that prioritizes the information used to measure fair value into three broad levels.

Under the fair value hierarchy, Management uses certain assumptions and judgments to derive the fair value of its investments, particularly for those assets with significant unobservable inputs, commonly referred to as Level 3 assets. At September 30, 2013, the Company’s financial instruments that were measured at fair value and categorized as Level 3 were as follows (in millions of U.S. dollars):


	September 30, 2013
Fixed maturities	$	842
Equities		33
Other invested assets (including certain derivatives)		96
Funds held—directly managed account		16

Total	$	987

For additional information on the valuation techniques, methods and assumptions that were used by the Company to estimate the fair value of its fixed maturities, short-term investments, equities, other invested assets and investments underlying the funds held – directly managed account, see Note 3 to Condensed Consolidated Financial Statements included in Item 1 of Part I of this report. For information on the Company’s use of derivative financial instruments, see Note 4 to Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.

Results of Operations—for the Three Months and Nine Months Ended September 30, 2013 and 2012

The following discussion of Results of Operations contains forward-looking statements based upon assumptions and expectations concerning the potential effect of future events that are subject to uncertainties. See Item 1A of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a complete list of the Company’s risk factors. Any of these risk factors could cause actual results to differ materially from those reflected in such forward-looking statements.

The Company’s reporting currency is the U.S. dollar. The Company’s significant subsidiaries and branches have one of the following functional currencies: U.S. dollar, euro or Canadian dollar. As a significant portion of the Company’s operations is transacted in foreign currencies, fluctuations in foreign exchange rates may affect year over year comparisons. To the extent that fluctuations in foreign exchange rates affect comparisons, their impact has been quantified, when possible, and discussed in each of the relevant sections. See Note 2(m) to Consolidated Financial Statements in Item 8 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of translation of foreign currencies.

The foreign exchange fluctuations for the principal currencies in which the Company transacts business were as follows:

•

the U.S. dollar average exchange rate was stronger against most currencies, except the Euro, in the three months and nine months ended September 30, 2013 compared to the same periods of 2012; and

•

the U.S. dollar ending exchange rate weakened against most currencies, except the Canadian dollar, at September 30, 2013 compared to December 31, 2012.

Review of Net Income

Management analyzes the Company’s net income or loss in three parts: underwriting result, investment result and other components of net income or loss. Underwriting result consists of net premiums earned and other income or loss less losses and loss expenses and life policy benefits, acquisition costs and other operating expenses. Investment result consists of net investment income, net realized and unrealized investment gains or losses and interest in earnings or losses of equity investments. Net investment income includes interest and dividends, net of investment expenses, generated by the Company’s investment activities, as well as interest income generated on funds held assets. Net realized and unrealized investment gains or losses include sales of the Company’s fixed income, equity and other invested assets and investments underlying the funds held – directly managed account and changes in net unrealized gains or losses. Interest in earnings or losses of equity investments includes the Company’s strategic investments. Other components of net income or loss include technical result and other income or loss, other operating expenses, interest expense, amortization of intangible assets, net foreign exchange gains or losses and income tax expense or benefit.

The components of net income for the three months and nine months ended September 30, 2013 and 2012 were as follows (in millions of U.S. dollars):


	For the three months ended September 30, 2013			% Change			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			% Change			For the nine months ended September 30, 2012

Amortization of intangible assets relates to intangible assets acquired in the acquisition of Paris Re in 2009 and Presidio in 2012.

Underwriting result is a measurement that the Company uses to manage and evaluate its Non-life and Life and Health segments, as it is a primary measure of underlying profitability for the Company’s core reinsurance operations, separate from the investment results. The Company believes that in order to enhance the understanding of its profitability, it is useful for investors to evaluate the components of net income or loss separately and in the aggregate. Underwriting result should not be considered a substitute for net income or loss and does not reflect the overall profitability of the business, which is also impacted by investment results and other items.

The following table provides the components of the underwriting result and combined ratio for the Non-life segment for the three months and nine months ended September 30, 2013 and 2012 and the components are discussed further below (in millions of U.S. dollars):

Three-month result

The underwriting result for the Non-life segment increased by $96 million (corresponding to a decrease of 5.8 points on the combined ratio), from $201 million (80.7 points on the combined ratio) in the three months ended September 30, 2012 to $297 million (74.9 points on the combined ratio) in the same period of 2013. The increase in the Non-life underwriting result and the corresponding decrease in the combined ratio in the three months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

Net favorable prior year loss development – an increase of $49 million (decrease of 2.1 points on the technical ratio) from $189 million (18.2 points on the technical ratio) in the three months ended September 30, 2012 to $238 million (20.3 points on the technical ratio) in the same period of 2013. The increase in net favorable prior year loss development was primarily driven by increases in the North America and Catastrophe sub-segments. The components of the net favorable prior year loss development are described in more detail in the discussion of individual sub-segments in Results by Segment below.

•

Large catastrophic losses and large losses – a decrease of $30 million (decrease of 3.5 points on the technical ratio) from $85 million (8.2 points on the technical ratio) related to the U.S. drought impacting the agriculture line of business of the North America sub-segment in the three months ended September 30, 2012 to $55 million (4.7 points on the technical ratio) in the same period of 2013 related to the German Hailstorm.

•

Net favorable prior quarters’ loss development – an increase of $12 million (decrease of 0.7 points on the technical ratio) from $17 million (1.7 points on the technical ratio) in the three months ended September 30, 2012 to $29 million (2.4 points on the technical ratio) in the same period of 2013. The net favorable prior quarters’ loss development in the three months ended September 30, 2013 was driven by the Catastrophe sub-segment and is described in more detail in Results by Segment below.

•

The current accident year technical result, adjusted for large catastrophic losses, large losses and prior quarters’ loss development – was comparable in the three months ended September 30, 2013 and 2012 reflecting a low level of attritional losses in the North America sub-segment and upward premium adjustments and lower loss picks in the Global (Non-U.S.) P&C sub-segment in 2013. These increases were offset by a higher level of mid-sized loss activity and higher acquisition costs driven by profit commissions in the Specialty sub-segment in 2013 compared to the same period of 2012. While the current accident year technical result increased modestly in the three months ended September 30, 2013 compared to the same period of 2012, the corresponding technical ratio also increased modestly due to a shift in the mix of business resulting from a relatively lower level of catastrophe business as a proportion of the Non-life segment.

The underwriting result for the Life and Health segment, which does not include allocated investment income, improved by $10 million, from breakeven in the three months ended September 30, 2012 to $10 million in the same period of 2013. The improvement in the Life and Health underwriting result was primarily due to higher net favorable loss development, which was driven by the mortality line of business. See Results by Segment below.

Net investment income decreased by $13 million, from $135 million in the three months ended September 30, 2012 to $122 million in the same period of 2013. The decrease in net investment income was primarily attributable to a decrease in net investment income from fixed maturities due to lower reinvestment rates. See Corporate and Other – Net Investment Income below for more details.

Net realized and unrealized investment gains decreased by $241 million, from $257 million in the three months ended September 30, 2012 to $16 million in the same period of 2013. The net realized and unrealized investment gains of $16 million in the three months ended September 30, 2013 were primarily due to narrowing credit spreads and modest improvements in worldwide equity markets, which were partially offset by losses related to treasury futures and increases in U.S. and European risk-free interest rates. See Corporate and Other – Net Realized and Unrealized Investment Gains (Losses) below for more details.

Other operating expenses included in Corporate and Other increased by $4 million, from $25 million in the three months ended September 30, 2012 to $29 million in the same period of 2013. The increase was primarily due to an increase in information technology costs.

Interest expense in the three months ended September 30, 2013 was comparable to the same period of 2012.

Net foreign exchange losses decreased modestly, from $2 million in the three months ended September 30, 2012 to $1 million in the same period of 2013. The net foreign exchange loss for the three months ended September 30, 2013 resulted primarily from currency movements on certain unhedged equity securities, which were partially offset by the difference in the forward points embedded in the Company’s hedges. The Company hedges a significant portion of its currency risk exposure as discussed in Quantitative and Qualitative Disclosures about Market Risk in Item 3 of Part I of this report.

Income tax expense increased by $6 million, from $64 million in the three months ended September 30, 2012 to $70 million in the same period of 2013, reflecting a relatively higher distribution of the Company’s pre-tax net income to taxable jurisdictions in the three months ended September 30, 2013 compared to the same period of 2012. See Corporate and Other – Income Taxes below for more details.

Nine-month result

The underwriting result for the Non-life segment increased by $79 million (corresponding to a decrease of 0.9 points on the combined ratio), from $408 million (85.1 points on the combined ratio) in the nine months ended September 30, 2012 to $487 million (84.2 points on the combined ratio) in the same period of 2013. The increase in the Non-life underwriting result and the corresponding decrease in the combined ratio in the nine months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

Net favorable prior year loss development – an increase of $80 million (decrease of 0.7 points on the technical ratio) from $468 million (17.2 points on the technical ratio) in the nine months ended September 30, 2012 to $548 million (17.9 points on the technical ratio) in the same period of 2013. The increase in net favorable prior year loss development was primarily driven by increases in the Catastrophe and Global (Non-U.S.) P&C sub-segments, which were partially offset by decreases in the Global Specialty and North America sub-segments. The components of the net favorable prior year loss development are described in more detail in the discussion of individual sub-segments in Results by Segment below.

•

The current accident year technical result, adjusted for large catastrophic losses and large losses - an increase in the technical result (and a corresponding decrease in the technical ratio) primarily driven by the inclusion of premium adjustments and related acquisition costs of $29 million in the nine months ended September 30, 2012 in the agriculture line of business of the North America sub-segment, which were directly associated with favorable prior year loss development on the 2011 underwriting year. Adjusting for this impact, the increase in the current accident year technical result was primarily due to the same factors described in the three-month result above.

These factors driving the increase in the Non-life underwriting result and the corresponding decrease in the combined ratio in the nine months ended September 30, 2013 compared to the same period of 2012 were partially offset by:

•

Large catastrophic losses and large losses - an increase of $71 million (increase of 2.1 points on the technical ratio) from $85 million (3.1 points on the technical ratio) in the nine months ended September 30, 2012 related to the U.S. drought that impacted the agriculture line of the North America sub-segment to $156 million (5.2 points on the technical ratio) in the same period of 2013 related to the Alberta Floods, German Hailstorm and European Floods.

The underwriting result for the Life and Health segment, which does not include allocated investment income, improved by $22 million, from a loss of $7 million in nine months ended September 30, 2012 to a gain of $15 million in the same period of 2013. The improvement in the Life and Health underwriting result was primarily due to higher net favorable loss development, driven by the mortality line of business. See Results by Segment below.

Net investment income decreased by $66 million, from $436 million in the nine months ended September 30, 2012 to $370 million in the same period of 2013. The decrease in net investment income was primarily attributable to a decrease in net investment income from fixed maturities due to lower reinvestment rates. See Corporate and Other – Net Investment Income below for more details.

Net realized and unrealized investment losses increased by $748 million, from gains of $488 million in the nine months ended September 30, 2012 to losses of $260 million in the same period of 2013. The net realized and unrealized investment losses of $260 million in the nine months ended September 30, 2013 were primarily due to increases in the U.S. and European risk-free interest rates. See Corporate and Other – Net Realized and Unrealized Investment Gains (Losses) below for more details.

Other operating expenses included in Corporate and Other increased by $54 million, from $74 million in the nine months ended September 30, 2012 to $128 million in the same period of 2013. The increase was primarily due to a charge related to the restructuring described in Overview above in the nine months ended September 30, 2013.

Interest expense in the nine months ended September 30, 2013 was comparable to the same period of 2012.

Net foreign exchange losses increased by $13 million, from gains of $3 million in the nine months ended September 30, 2012 to losses of $10 million in the same period of 2013. The net foreign exchange losses during the nine months ended September 30, 2013 resulted primarily from currency movements on certain unhedged equity securities. The Company hedges a significant portion of its currency risk exposure as discussed in Quantitative and Qualitative Disclosures about Market Risk in Item 3 of Part I of this report.

Income tax expense increased by $144 million, from $181 million in the nine months ended September 30, 2012 to $37 million in the same period of 2013, reflecting a decrease in pre-tax net income in the nine months ended September 30, 2013 compared to the same period of 2012. See Corporate and Other – Income Taxes below for more details.

Results by Segment

The Company monitors the performance of its operations in three segments, Non-life, Life and Health and Corporate and Other. The Non-life segment is further divided into four sub-segments, North America, Global (Non-U.S.) Property and Casualty (Global (Non-U.S.) P&C), Global Specialty and Catastrophe. Segments and sub-segments represent markets that are reasonably homogeneous in terms of geography, client types, buying patterns, underlying risk patterns and approach to risk management. See the description of the Company’s segments and sub-segments as well as a discussion of how the Company measures its segment results in Note 20 to Consolidated Financial Statements included in Item 8 of Part II of Form 10-K for the year ended December 31, 2012 and in Note 10 to Consolidated Financial Statements included in Item 1 of Part I of this report. Effective January 1, 2013, the Life segment is referred to as Life and Health to reflect the inclusion of Presidio’s results following its acquisition on December 31, 2012 and the Global (Non-U.S.) Specialty sub-segment is referred to as Global Specialty.

Non-life Segment

North America

The North America sub-segment is comprised of lines of business that are considered to be either short, medium or long-tail. The short-tail lines consist primarily of agriculture, property and motor business. Casualty is considered to be long-tail, while credit/surety and multiline are considered to have a medium tail. The casualty line typically tends to have a higher loss ratio and a lower technical result due to the long-tail nature of the risks involved. Casualty treaties typically provide for investment income on premiums invested over a longer period as losses are typically paid later than for other lines. Investment income, however, is not considered in the calculation of technical result.

The following table provides the components of the technical result and the corresponding ratios for this sub-segment for the three months and nine months ended September 30, 2013 and 2012 (in millions of U.S. dollars):

Three-month result

Gross and net premiums written increased by 31% and net premiums earned increased by 27% in the three months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned were primarily attributable to the agriculture line of business and were driven by new business written and, to a lesser extent, upward premium adjustments related to a significant treaty in the three months ended September 30, 2013.

Nine-month result

Gross and net premiums written and net premiums earned increased by 33%, 32% and 29%, respectively, in the nine months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned were primarily attributable to the agriculture line of business due to the same factors described in the three-month result and the casualty line of business driven by new business written. Notwithstanding the diverse conditions prevailing in various markets within this sub-segment, the Company was able to write business that met its portfolio objectives.

Large catastrophic losses and large losses are shown net of any related reinsurance, reinstatement premiums and profit commissions.

Three-month result

The increase of $126 million in the technical result (and the corresponding decrease of 29.5 points on the technical ratio) in the three months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

Large catastrophic losses and large losses – a decrease of $85 million (decrease of 25.4 points on the technical ratio) related to the U.S. drought impacting the agriculture line of business in the three months ended September 30, 2012 compared to no significant catastrophic losses and large losses in the three months ended September 30, 2013.

•

Net favorable prior year loss development – an increase of $27 million (decrease of 2.3 points on the technical ratio) from $67 million (19.9 points on the technical ratio) in the three months ended September 30, 2012 to $94 million (22.2 points on the technical ratio) in the same period of 2013. The net favorable loss development for prior accident years in the three months ended September 30, 2013 and 2012 was driven by most lines of business, with the casualty line being the most pronounced.

•

The current accident year technical result, adjusted for large catastrophic losses, large losses and prior quarters’ loss development – an increase in the technical result (and corresponding decrease in the technical ratio) primarily due to a low level of attritional losses in the property line of business during the three months ended September 30, 2013 and normal fluctuations in profitability between periods.

These factors driving the increase in the technical result in the three months ended September 30, 2013 compared to the same period of 2012 were partially offset by:

•

Net adverse prior quarters’ loss development – an increase of $8 million (increase of 1.9 points on the technical ratio) related to the Alberta Floods.

Nine-month result

The increase of $104 million in the technical result (and the corresponding decrease of 7.3 points on the technical ratio) in the nine months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

Large catastrophic losses and large losses – a decrease of $69 million (decrease of 8.5 points on the technical ratio) from $85 million (9.9 points on the technical ratio) related to the U.S. drought impacting the agriculture line of business in the nine months ended September 30, 2012 to $16 million (1.4 points on the technical ratio) related to the Alberta Floods in the same period of 2013.

•

The current accident year technical result, adjusted for large catastrophic losses and large losses – an increase in the technical result (and corresponding decrease in the technical ratio) primarily due to the inclusion of prior year premium adjustments and related acquisition costs of approximately $29 million in the agriculture line of business in the nine months ended September 30, 2012, which were directly associated with favorable prior year loss development on the 2011 underwriting year. Adjusting for this impact, the current accident year technical result increased primarily due to a modestly lower level of mid-sized loss activity and normal fluctuations in profitability between periods.

These factors driving the increase in the technical result in the nine months ended September 30, 2013 compared to the same period of 2012 were partially offset by:

•

Net favorable prior year loss development – a decrease of $12 million (increase of 5.5 points on the technical ratio) from $167 million (19.4 points on the technical ratio) in the nine months ended September 30, 2012 to $155 million (13.9 points on the technical ratio) in the same period of 2013. The net favorable loss development for prior accident years in the nine months ended September 30, 2013 was driven by most lines of business, with the casualty line being the most pronounced, while the credit/surety and agriculture lines experienced combined adverse loss development for prior accident years of $8 million. The net favorable loss development for prior accident years in the nine months ended September 30, 2012 was driven by most lines of business, with the casualty line being the most pronounced.

Global (Non-U.S.) P&C

The Global (Non-U.S.) P&C sub-segment is composed of short-tail business, in the form of property and proportional motor business, that represented approximately 90% and 83% of net premiums written in the three months and nine months ended September 30, 2013, respectively, and long-tail business, in the form of casualty and non-proportional motor business, that represented the balance of net premiums written.

Business reported in this sub-segment is, to a significant extent, originally denominated in foreign currencies and is reported in U.S. dollars. The U.S. dollar can fluctuate significantly against other currencies and this should be considered when making period to period comparisons. The following table summarizes the effect of foreign exchange fluctuations, described in the Results of Operations above, on gross and net premiums written and net premiums earned in the three months and nine months ended September 30, 2013 compared to the same periods of 2012:

Three-month result

Gross and net premiums written and net premiums earned increased by 28%, 29% and 12% on a constant foreign exchange basis, respectively, in the three months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned resulted primarily from new business written in the motor line of business at the January 1, 2013 renewal and upward premium adjustments in the property line of business. The increase in net premiums earned was lower than the increases in gross and net premiums written due to the effect of cancellations and non-renewals in the property line of business during the second half of 2012.

Nine-month result

Gross and net premiums written increased by 15% and net premiums earned increased by 7% on a constant foreign exchange basis, respectively, in the nine months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned resulted primarily from the new motor business described in the three-month result. The increase in net premiums earned was lower than the increases in gross and net premiums written due to the same factor described in the three-month result. Notwithstanding the continued competitive conditions in most markets, the Company was able to write business that met its portfolio objectives.

Three-month result

The increase of $35 million in the technical result (and the corresponding decrease of 17.1 points on the technical ratio) in the three months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

The current accident year technical result, adjusted for large catastrophic losses and prior quarters’ loss development – an increase in the technical result (and a corresponding decrease in the technical ratio) due to higher upward premium adjustments reported by cedants, lower loss picks in certain lines of business and a modestly lower level of mid-sized loss activity in the three months ended September 30, 2013 compared to the same period of 2012, partially offset by normal fluctuations in profitability between periods.

•

Net favorable (adverse) prior quarters’ loss development – an increase of $12 million in the technical result (decrease of 6.3 points on the technical ratio) from adverse development of $4 million (2.3 points on the technical ratio) in the three months ended September 30, 2012 to favorable development of $8 million (4.0 points on the technical ratio) in the same period of 2013.

•

Net favorable prior year loss development – an increase of $9 million (decrease of 2.5 points on the technical ratio) from $28 million (16.7 points on the technical ratio) in the three months ended September 30, 2012 to $37 million (19.2 points on the technical ratio) in the same period of 2013. The net favorable loss development for prior accident years in the three months ended September 30, 2013 was driven by all lines of business, with the property line being the most pronounced. The net favorable loss development for prior accident years in the three months ended September 30, 2012 was driven by all lines of business.

Nine-month result

The increase of $84 million in the technical result (and the corresponding decrease of 15.3 points on the technical ratio) in the nine months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

Net favorable prior year loss development – an increase of $57 million (decrease of 9.8 points on the technical ratio) from $74 million (15.0 points on the technical ratio) in the nine months ended September 30, 2012 to $131 million (24.8 points on the technical ratio) in the same period of 2013. The net favorable loss development for prior accident years in the nine months ended September 30, 2013 was driven by all lines of business, with the property line being the most pronounced and included favorable loss emergence related to certain catastrophic and large loss events. The net favorable loss development for prior accident years in the nine months ended September 30, 2012 was driven by all lines of business.

•

The current accident year technical result, adjusted for large catastrophic losses – an increase in the technical result (and a corresponding decrease in the technical ratio) due to lower loss picks in certain lines of business, a lower level of mid-sized loss activity and higher upward premium adjustments reported by cedants in the nine months ended September 30, 2013 compared to the same period of 2012, partially offset by normal fluctuations in profitability between periods.

These factors driving the increase in the technical result in the nine months ended September 30, 2013 compared to the same period of 2012 were partially offset by:

•

Large catastrophic losses – an increase of $14 million (increase of 2.6 points on the technical ratio) related to the European Floods and German Hailstorm compared to no large catastrophic losses in the nine months ended September 30, 2012.

Global Specialty

The Global Specialty sub-segment is primarily comprised of lines of business that are considered to be either short, medium or long-tail. The short-tail lines consist of agriculture, energy and specialty property. Aviation/space, credit/surety, engineering and marine are considered to have a medium tail, while specialty casualty is considered to be long-tail.

Three-month result

Gross and net premiums written and net premiums earned increased by 9%, 8% and 4% on a constant foreign exchange basis, respectively, in the three months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned were primarily driven by new business written in most lines of business and upward premium adjustments in the credit/surety line. These increases in gross and net premiums written and net premiums earned were partially offset by cancellations and non-renewals in the marine line of business. The increase in net premiums earned was lower than the increases in gross and net premiums written as the new business written during the three months ended September 30, 2013 is not yet fully reflected in net premiums earned.

Nine-month result

Gross premiums written increased by 6% and net premiums written and earned increased by 5% on a constant foreign exchange basis, respectively, in the nine months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned were primarily driven by the same factors described in the three-month result. These increases in gross and net premiums written and net premiums earned were partially offset by decreased participations in the aviation/space line of business and cancellations and non-renewals in the marine line of business. Notwithstanding the diverse conditions prevailing in various markets within this sub-segment, the Company was able to write business that met its portfolio objectives.

Three-month result

The decrease of $61 million in the technical result (and the corresponding increase of 17.7 points on the technical ratio) in the three months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

The current accident year technical result, adjusted for large catastrophic losses and prior quarters’ loss development – a decrease in the technical result (and corresponding increase in the technical ratio) due to a higher level of mid-sized loss activity, an increase in the acquisition cost ratio driven by higher profit commission adjustments in the aviation/space and marine lines and a decrease in upward premium adjustments reported by cedants in the three months ended September 30, 2013 compared to the same period of 2012. These decreases in the technical result were partially offset by lower loss picks in certain lines of business and normal fluctuations in profitability between periods.

•

Net (adverse) favorable prior quarters’ loss development – a decrease of $17 million in the technical result (increase of 4.7 points on the technical ratio) from $16 million (4.4 points on the technical ratio) in the three months ended September 30, 2012.

•

Net favorable prior year loss development – a decrease of $13 million (increase of 4.6 points on the technical ratio) from $91 million (25.0 points on the technical ratio) in the three months ended September 30, 2012 to $78 million (20.4 points on the technical ratio) in the same period of 2013. The net favorable loss development for prior accident years in the three months ended September 30, 2013 and 2012 was driven by all lines of business, and was most pronounced in the marine, aviation/space and specialty property lines.

Nine-month result

The decrease of $87 million in the technical result (and the corresponding increase of 9.1 points on the technical ratio) in the nine months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

Net favorable prior year loss development – a decrease of $39 million (increase of 4.6 points on the technical ratio) from $205 million (19.8 points on the technical ratio) in the nine months ended September 30, 2012 to $166 million (15.2 points on the technical ratio) in the same period of 2013. The net favorable loss development for prior accident years in the nine months ended September 30, 2013 and 2012 was driven by most lines of business, predominantly the aviation/space, marine and specialty property lines.

•

The current accident year technical result, adjusted for large catastrophic losses – a decrease in the technical result (and corresponding increase in the technical ratio) due to a higher level of mid-sized loss activity and a decrease in upward premium adjustments reported by cedants in the nine months ended September 30, 2013 compared to the same period of 2012, partially offset by lower loss picks in certain lines of business and normal fluctuations in profitability.

•

Large catastrophic losses – an increase of $21 million (increase of 1.9 points on the technical ratio) related to the Alberta and European Floods compared to no large catastrophic events in the nine months ended September 30, 2012.

Catastrophe

The Catastrophe sub-segment writes business predominantly on a non-proportional basis and is exposed to volatility resulting from catastrophic losses. Thus, profitability in any one quarter is not necessarily predictive of future profitability. The results for the three months and nine months ended September 30, 2013 and 2012 demonstrate this volatility. The three months ended September 30, 2013 included a modestly higher level of large catastrophic losses resulting from the German Hailstorm and the nine months ended September 30, 2013 included a higher level of large catastrophic losses resulting from the Alberta Floods, German Hailstorm and European Floods. The results for the three months and nine months ended September 30, 2012 contained no significant catastrophic losses. The varying amounts of catastrophic losses can significantly impact the technical result and ratio and affect year over year comparisons as discussed below.

The Catastrophe sub-segment results are presented before the inter-company quota share of a diversified portfolio of catastrophe treaties to the Company’s fully collateralized reinsurance vehicle, Lorenz Re Ltd. (see Note 7 to the Unaudited Condensed Consolidated Financial Statements included in Item 1 of Part I of this report).

Premiums

The Catastrophe sub-segment represented 6% and 10% of total net premiums written in the three months and nine months ended September 30, 2013 and 2012, respectively, compared to 6% and 12% of total net premiums written in the same periods of 2012.

Business reported in this sub-segment is, to an extent, originally denominated in foreign currencies and is reported in U.S. dollars. The U.S. dollar can fluctuate significantly against other currencies and this should be considered when making period to period comparisons. The following table summarizes the effect of foreign exchange fluctuations, described in the Results of Operations above, on gross and net premiums written and net premiums earned in the three months and nine months ended September 30, 2013 compared to the same periods of 2012:


	Gross premiums written			Net premiums written			Net premiums earned

Three-month result

Gross and net premiums written increased by 10% and net premiums earned increased by 3% on a constant foreign exchange basis in the three months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written were primarily due to new business written in the three months ended September 30, 2013, which was partially offset by cancellations and non-renewals due to lower pricing and cedant program restructurings. Net premiums earned are normally significantly higher than gross and net premiums written during the three months ended September 30, 2013 due to the seasonality of the earnings pattern for U.S. wind business, which results in higher earned premiums being recognized in quarters with more exposure.

Nine-month result

Gross premiums written increased by 2% and net premiums written and earned increased by 3% on a constant foreign exchange basis in the nine months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned were primarily due to new business and reinstatement premiums related to the European and Alberta Floods, and were partially offset by cancellations and non-renewals.

Large catastrophic losses are shown net of any related reinsurance, reinstatement premiums and profit commissions.

Three-month result

The technical result and technical ratio in the three months ended September 30, 2013 were comparable to the same period of 2012 as a result of:

•

Large catastrophic losses – an increase of $52 million (increase of 30.7 points on the technical ratio) related to the German Hailstorm compared to no significant catastrophic losses in the three months ended September 30, 2012.

This factor driving the decrease in the technical result in the three months ended September 30, 2013 compared to the same period of 2012 was almost entirely offset by:

•

Net favorable prior year loss development – an increase of $26 million (decrease of 15.1 points on the technical ratio) from $3 million (1.7 points on the technical ratio) in the three months ended September 30, 2012 to $29 million (16.8 points on the technical ratio) in the same period of 2013. The net favorable loss development for prior accident years in the three months ended September 30, 2013 and 2012 was primarily due to favorable loss emergence.

•

Net favorable prior quarters’ loss development – an increase of $25 million (decrease of 14.7 points on the technical ratio) in the three months ended September 30, 2012 to $30 million (17.6 points on the technical ratio) compared to the same period of 2012. The net favorable prior quarters’ loss development in the three months ended September 30, 2013 included favorable development related to the Alberta and European Floods.

The current accident year technical result and ratio, adjusted for large catastrophic losses and prior quarters’ loss development, in the three months ended September 30, 2013 was comparable to the same period of 2012.

Nine-month result

The decrease of $21 million in the technical result (and the corresponding increase of 7.4 points on the technical ratio) in the nine months ended September 30, 2013 compared to the same period of 2012 was primarily attributable to:

•

Large catastrophic losses – an increase of $105 million (increase of 35.1 points on the technical ratio) related to the German Hailstorm, Alberta Floods and European Floods compared to no significant catastrophic losses in the nine months ended September 30, 2012.

This factor driving the decrease in the technical result in the nine months ended September 30, 2013 compared to the same period of 2012 was partially offset by:

•

Net favorable prior year loss development – an increase of $74 million (decrease of 21.9 points on the technical ratio) from $22 million (6.5 points on the technical ratio) in the nine months ended September 30, 2012 to $96 million (28.4 points on the technical ratio) in the same period of 2013. The net favorable loss development for prior accident years in the nine months ended September 30, 2013 and 2012 was primarily due to favorable loss emergence.

•

The current accident year technical result, adjusted for large catastrophic losses – an increase in the technical result (and corresponding decrease in the technical ratio) primarily due to a modestly lower level of mid-sized loss activity and normal fluctuations in profitability and premiums earned between periods.

Life and Health Segment

Effective January 1, 2013, the Life and Health segment includes the results of Presidio, following its acquisition on December 31, 2012. This affects period over period comparisons, primarily in the accident and health line of business.

The following table provides the components of the allocated underwriting result for this segment for the three months and nine months ended September 30, 2013 and 2012 (in millions of U.S. dollars):

Business reported in this segment is, to a significant extent, originally denominated in foreign currencies and is reported in U.S. dollars. The U.S. dollar can fluctuate significantly against other currencies and this should be considered when making period to period comparisons. The following table summarizes the effect of foreign exchange fluctuations, described in the Results of Operations above, on gross and net premiums written and net premiums earned in the three months and nine months ended September 30, 2013 compared to the same periods of 2012:


	Gross premiums written			Net premiums written			Net premiums earned

Increase as reported in U.S. dollars		20	%		19	%		19	%

Three-month result

Gross premiums written increased by 24% and net premiums written and earned increased by 23% on a constant foreign exchange basis in the three months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned were primarily due to the inclusion of Presidio’s gross and net premiums written and net premiums earned in the accident and health line of business in the three months ended September 30, 2013 and, to a lesser extent, growth in the mortality line of business.

Nine-month result

Gross premiums written increased by 19% and net premiums written and earned increased by 18% on a constant foreign exchange basis in the nine months ended September 30, 2013 compared to the same period of 2012. The increases in gross and net premiums written and net premiums earned were primarily due to the same factors described in the three-month result.

Allocated underwriting result

Three-month result

The allocated underwriting result increased by $10 million, from $15 million in the three months ended September 30, 2012 to $25 million in the same period of 2013. The increase was primarily driven by a higher level of net favorable prior year loss development in the three months ended September 30, 2013 compared to the same period of 2012 and the inclusion of Presidio’s results. These factors driving the increase in the allocated underwriting result were partially offset by higher operating expenses.

The increase in net favorable prior year loss development of $7 million resulted from net favorable loss development of $13 million in the three months ended September 30, 2013 compared to net favorable loss development of $6 million in the same period of 2012. The net favorable prior year loss development of $13 million during the three months ended September 30, 2013 was primarily related to the GMDB business, driven by favorable claims experience and improvements in the capital markets. The net favorable prior year loss development of $6 million in the three months ended September 30, 2012 was primarily related to the GMDB business, driven by improvements in the capital markets.

Other operating expenses increased by $5 million, from $12 million in the three months ended September 30, 2012 to $17 million in the same period of 2013 primarily due to the inclusion of Presidio’s operating expenses. The overall impact on the allocated underwriting result of including Presidio’s operating expenses was partially offset by the Managing General Agent (MGA) fees earned by Presidio, which are included in other income.

Nine-month result

The allocated underwriting result increased by $18 million, from $42 million in the nine months ended September 30, 2012 to $60 million in the same period of 2013. The increase was primarily driven by a higher level of net favorable prior year loss development in the nine months ended September 30, 2013 compared to the same period of 2012, the inclusion of Presidio’s results and an increase in other income. These factors driving the increase in the allocated underwriting result were partially offset by higher operating expenses.

The increase in net favorable prior year loss development of $18 million resulted from net favorable loss development of $33 million in the nine months ended September 30, 2013 compared to $15 million in the same period of 2012. The net favorable prior year loss development of $33 million and $15 million during the nine months ended September 30, 2013 and 2012, respectively, was primarily related to the GMDB business, as described in the three-month result, and certain short-term treaties in the mortality line of business.

Other income increased by $6 million, from $3 million in the nine months ended September 30, 2012 to $9 million in the same period of 2013 primarily due to the inclusion of the MGA fees earned by Presidio.

Other operating expenses increased by $14 million, from $38 million in the nine months ended September 30, 2012 to $52 million in the same period of 2013 primarily due to the same factor described in the three-month result.

Premium Distribution by Line of Business

The distribution of net premiums written by line of business for the three months and nine months ended September 30, 2013 and 2012 was as follows:


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012

Total		100	%		100	%		100	%		100	%

The changes in the distribution of net premiums written by line of business between the three months and nine months ended September 30, 2013 and the same periods of 2012 reflected the Company’s response to existing market conditions and may also be affected by the timing of renewals of treaties, a change in treaty structure, premium adjustments reported by cedants and significant increases or decreases in other lines of business. In addition, foreign exchange fluctuations affected the comparison for all lines.

•

Multiline and other: the increase in the distribution of net premiums written in the three months and nine months ended September 30, 2013 compared to the same periods of 2012 was driven by new business written in the North America and Global Specialty sub-segments.

•

Agriculture: the increase in the distribution of net premiums written in the three months and nine months ended September 30, 2013 compared to the same periods of 2012 was primarily driven by new business written in the North America sub-segment and, to a lesser extent, the Global Specialty sub-segment.

•

Marine: the decrease in the distribution of net premiums written in the three months and nine months ended September 30, 2013 compared to the same periods of 2012 was driven by cancellations and non-renewals in the Global Specialty sub-segment.

Premium Distribution by Reinsurance Type

The Company typically writes business on either a proportional or non-proportional basis. On proportional business, the Company shares proportionally in both the premiums and losses of the cedant. On non-proportional business, the Company is typically exposed to loss events in excess of a predetermined dollar amount or loss ratio. In both proportional and non-proportional business, the Company typically reinsures a large group of primary insurance contracts written by the ceding company. In addition, the Company writes business on a facultative basis. Facultative arrangements are generally specific to an individual risk and can be written on either a proportional or non-proportional basis. Generally, the Company has more influence over pricing, as well as terms and conditions, in non-proportional and facultative arrangements.

The distribution of gross premiums written by reinsurance type for the three months and nine months ended September 30, 2013 and 2012 was as follows:


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012
Non-life segment
Proportional		59	%		54	%		52	%		48	%
Non-proportional		15			18			25			29
Facultative		8			10			6			7
Life and Health segment
Proportional		18			18			16			15
Non-proportional		—			—			1			1

Total		100	%		100	%		100	%		100	%

The distribution of gross premiums written by reinsurance type is affected by changes in the allocation of capacity among lines of business, the timing of receipt by the Company of cedant accounts and premium adjustments by cedants. In addition, foreign exchange fluctuations affected the comparison for all treaty types.

The changes in the distribution of gross premiums written by reinsurance type between the three months and nine months ended September 30, 2013 and the same periods of 2012 reflect a shift from non-proportional business to proportional business in the Non-life segment. This shift was driven by all Non-life sub-segments, except for the Catastrophe sub-segment, and specifically included an increase in gross premiums written in the agriculture line of business, which is predominantly written on a proportional basis. In addition, the shift was also driven by a relative decrease in the Catastrophe sub-segment’s gross premiums written, which are predominantly written on a non-proportional basis, as a percentage of total gross premiums written due to larger increases in gross premiums written in all other Non-life sub-segments and the Life and Health segment.

Premium Distribution by Geographic Region

The following table provides the geographic distribution of gross premiums written based on the location of the underlying risk for the three months and nine months ended September 30, 2013 and 2012:


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012
Asia, Australia and New Zealand		11	%		12	%		11	%		11	%
Europe		35			37			40			42
Latin America, Caribbean and Africa		12			13			10			11
North America		42			38			39			36

Total		100	%		100	%		100	%		100	%

The increase in the distribution of gross premiums written in North America during the three months and nine months ended September 30, 2013 compared to the same periods of 2012 was primarily due to an increase in gross premiums written in the Company’s North America Non-life sub-segment and in the Life and Health segment. The increase in the North America sub-segment was driven by the agriculture line of business in the three months ended September 30, 2013 and by the agriculture and casualty lines in the nine months ended September 30, 2013 compared to the same periods of 2012. The increase in the Life and Health segment was driven by the inclusion of Presidio’s business from January 1, 2013.

Premium Distribution by Production Source

The Company generates its gross premiums written both through brokers and through direct relationships with cedants. The percentage of gross premiums written by production source for the three months and nine months ended September 30, 2013 and 2012 was as follows:


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012
Broker		72	%		70	%		71	%		70	%
Direct		28			30			29			30

Total		100	%		100	%		100	%		100	%

The percentage of gross premiums written through brokers in the three months and nine months ended September 30, 2013 compared to the same periods of 2012 increased slightly due to an increase in the percentage of gross premiums written through brokers in Europe and North America and the inclusion of Presidio’s business, which is solely written through brokers.

Corporate and Other

Corporate and Other is comprised of the Company’s capital markets and investment related activities, including principal finance transactions, insurance-linked securities and strategic investments, and its corporate activities, including other operating expenses.

Net Investment Income

The table below provides net investment income by asset source for the three months and nine months ended September 30, 2013 and 2012 (in millions of U.S. dollars):


	For the three months ended September 30, 2013			% Change			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			% Change			For the nine months ended September 30, 2012

Because of the interest-sensitive nature of some of the Company’s Life and Health products, net investment income is considered in Management’s assessment of the profitability of the Life and Health segment (see Life and Health segment above). The following discussion includes net investment income from all investment activities, including the net investment income allocated to the Life and Health segment.

Three-month result

Net investment income decreased in the three months ended September 30, 2013 compared to the same period of 2012 due to:

•

a decrease in net investment income from fixed maturities primarily as a result of lower reinvestment rates and cash outflows from the fixed maturity portfolio primarily to finance the Company’s share repurchase activity; partially offset by

•

an increase in net investment income from equities primarily as a result of higher dividend income.

Nine-month result

Net investment income decreased in the nine months ended September 30, 2013 compared to the same period of 2012 primarily due to:

•

a decrease in net investment income from funds held and other primarily due to lower investment income reported by cedants; and

•

a decrease in net investment income from funds held – directly managed primarily related to the lower average balance in the funds held – directly managed account and lower reinvestment rates.

Net Realized and Unrealized Investment Gains (Losses)

The Company’s portfolio managers have dual investment objectives of optimizing current investment income and achieving capital appreciation. To meet these objectives, it is often desirable to buy and sell securities to take advantage of changing market conditions and to reposition the investment portfolios. Accordingly, recognition of realized gains and losses is considered by the Company to be a normal consequence of its ongoing investment management activities. In addition, the Company records changes in fair value for substantially all of its investments as unrealized investment gains or losses in its Condensed Consolidated Statements of Operations. Realized and unrealized investment gains and losses are generally a function of multiple factors, with the most significant being prevailing interest rates, credit spreads, and equity market conditions.

The components of net realized and unrealized investment gains (losses) for the three months and nine months ended September 30, 2013 and 2012 were as follows (in millions of U.S. dollars):


	For the three months ended September 30, 2013			For the three months ended September 30, 2012			For the nine months ended September 30, 2013			For the nine months ended September 30, 2012
Net realized investment gains on fixed maturities and short-term investments	$	19		$	44		$	100		$	123
Net realized investment gains on equities		15			5			69			53

Net realized and unrealized investment gains (losses)	$	16		$	257		$	(260	)	$	488

Three-month result

Net realized and unrealized investment gains decreased by $241 million, from $257 million in the three months ended September 30, 2012 to $16 million in the same period of 2013. The net realized and unrealized investment gains of $16 million in the three months ended September 30, 2013 were primarily due to realized gains on treasury note futures, narrowing credit spreads and modest improvements in worldwide equity markets, which were partially offset by unrealized losses on treasury note futures and increases in U.S. and European risk-free interest rates.

Net realized gains and the change in net unrealized investment losses on other invested assets were a combined loss of $24 million in the three months ended September 30, 2013 and primarily related to treasury note futures. Net realized and the change in net unrealized investment losses on other invested assets were a combined loss of $4 million in the three months ended September 30, 2012 and primarily related to net realized and unrealized losses on treasury note futures which were partially offset by realized gains on commodity futures and private placement investments and unrealized gains on weather derivatives.

Net realized and unrealized investment (losses) gains on funds held – directly managed of $1 million loss and $9 million gain in the three months ended September 30, 2013 and 2012, respectively, primarily related to the change in net unrealized investment (losses) gains on fixed maturities in the segregated investment portfolio underlying the funds held – directly managed account and were driven by changes in risk-free interest rates.

Nine-month result

Net realized and unrealized investment losses decreased by $748 million, from a gain of $488 million in the nine months ended September 30, 2012 to a loss of $260 million in the same period of 2013. The net realized and unrealized investment losses of $260 million in the nine months ended September 30, 2013 were primarily due to increases in U.S. and European risk-free interest rates and unrealized losses on treasury note futures, which were partially offset by realized gains on treasury note futures and improvements in worldwide equity markets.

Net realized gains and the change in net unrealized investment losses on other invested assets were a combined gain of $57 million in the nine months ended September 30, 2013 and primarily related to treasury note futures. Net realized losses and the change in net unrealized investment gains on other invested assets were a combined loss of $11 million in the nine months ended September 30, 2012 and primarily related to realized and unrealized losses on treasury note futures, which were partially offset by net unrealized gains on private placement investments and weather derivatives and realized gains on to-be-announced mortgage-backed securities (TBAs).

Net realized and unrealized investment (losses) gains on funds held – directly managed of $18 million loss and $18 million gain in the nine months ended September 30, 2013 and 2012, respectively, primarily related to the change in net unrealized investment (losses) gains on fixed maturities in the segregated investment portfolio underlying the funds held – directly managed account and were driven by changes in risk-free interest rates.

Other Operating Expenses

The Company’s total other operating expenses for the three months and nine months ended September 30, 2013 and 2012 were as follows (in millions of U.S. dollars):


	For the three months ended September 30, 2013		% Change			For the three months ended September 30, 2012		For the nine months ended September 30, 2013		% Change			For the nine months ended September 30, 2012
Other operating expenses	$	108		15	%	$	95	$	369		24	%	$	299

Three-month result

Other operating expenses represent 7.6% and 7.7% of net premiums earned (Non-life and Life and Health) for the three months ended September 30, 2013 and 2012, respectively. Other operating expenses included in Corporate and Other were $29 million and $25 million, of which $27 million and $23 million are related to corporate activities for the three months ended September 30, 2013 and 2012, respectively.

Other operating expenses increased by 15% in the three months ended September 30, 2013 compared to the same period of 2012 primarily due to higher information technology costs, the inclusion of Presidio’s operating expenses, the charges related to the restructuring and the impact of foreign exchange.

Nine-month result

Other operating expenses represent 9.8% and 9.0% of net premiums earned (Non-life and Life and Health) for the nine months ended September 30, 2013 and 2012, respectively. Other operating expenses included in Corporate and Other were $128 million and $74 million, of which $122 million and $64 million are related to corporate activities for the nine months ended September 30, 2013 and 2012, respectively.

Other operating expenses increased by 24% in the nine months ended September 30, 2013 compared to the same period of 2012 primarily due to the charges related to the restructuring, the inclusion of Presidio’s operating expenses and modestly higher personnel costs.

Income Taxes

The Company’s effective income tax rate, which we calculate as income tax expense or benefit divided by net income or loss before taxes, may fluctuate significantly from period to period depending on the geographic distribution of pre-tax net income or loss in any given period between different jurisdictions with comparatively higher tax rates and those with comparatively lower tax rates. The geographic distribution of pre-tax net income or loss can vary significantly between periods due to, but not limited to, the following factors: the business mix of net premiums written and earned; the geographic location, quantum and nature of net losses and loss expenses incurred; the quantum and geographic location of other operating expenses, net investment income, net realized and unrealized investment gains and losses; and the quantum of specific adjustments to determine the income tax basis in each of the Company’s operating jurisdictions. In addition, a significant portion of the Company’s gross and net premiums are currently written and earned in Bermuda, a non-taxable jurisdiction, including the majority of the Company’s catastrophe business, which can result in significant volatility in the Company’s pre-tax net income or loss from period to period.

The Company’s income tax expense and effective income tax rate for the three months and nine months ended September 30, 2013 and 2012 were as follows (in millions of U.S. dollars):


	For the three			For the three			For the nine			For the nine
	months ended			months ended			months ended			months ended
	September 30, 2013			September 30, 2012			September 30, 2013			September 30, 2012
Income tax expense	$	70		$	64		$	37		$	181
Effective income tax rate		17.4	%		11.6	%		8.7	%		15.1	%

Three-month result

Income tax expense and the effective income tax rate during the three months ended September 30, 2013 were $70 million and 17.4%, respectively. Income tax expense and the effective income tax rate during the three months ended September 30, 2013 were primarily driven by the geographic distribution of the Company’s pre-tax net income between its various taxable and non-taxable jurisdictions. The income tax expense and the effective income tax rate included a relatively even distribution of the Company’s pre-tax net income between its various jurisdictions. Specifically, the Company’s pre-tax net income recorded in non-taxable jurisdictions and jurisdictions with comparatively lower tax rates was driven by a relatively low level of catastrophe losses and net favorable prior year loss development. The Company’s pre-tax net income recorded in jurisdictions with comparatively higher tax rates was primarily due to net favorable prior year loss development, certain true-up to tax return adjustments and net realized and unrealized investment gains.

Income tax expense and the effective income tax rate during the three months ended September 30, 2012 were $64 million and 11.6%, respectively. Income tax expense and the effective income tax rate during the three months ended September 30, 2012 were primarily driven by the geographic distribution of the Company’s pre-tax net income between its various taxable and non-taxable jurisdictions. The income tax expense and the effective income tax rate included a relatively even distribution of the Company’s pre-tax net income between its various jurisdictions. Specifically, the Company’s pre-tax net income recorded in non-taxable jurisdictions and jurisdictions with comparatively lower tax rates was driven by the absence of catastrophe losses and net realized and unrealized gains. The Company’s pre-tax net income recorded in jurisdictions with comparatively higher tax rates was primarily due to net favorable prior year loss development and net realized and unrealized investment gains.

Nine-month result

Income tax expense and the effective income tax rate during the nine months ended September 30, 2013 were $37 million and 8.7%, respectively. Income tax expense and the effective income tax rate during the nine months ended September 30, 2013 were primarily driven by the geographic distribution of the Company’s pre-tax net income between its various taxable and non-taxable jurisdictions. Specifically, the income tax expense and the effective income tax rate included a significant portion of the Company’s pre-tax net income recorded in non-taxable jurisdictions and jurisdictions with comparatively lower tax rates driven by net favorable prior year loss development and partially offset by net realized and unrealized investment losses and catastrophe losses. The Company’s pre-tax net income recorded in jurisdictions with comparatively higher tax rates was driven by net favorable prior year loss development and certain true-up to tax return adjustments, which were partially offset by net realized and unrealized investment losses and catastrophe losses related to the Alberta and European Floods.

Income tax expense and the effective income tax rate during the nine months ended September 30, 2012 were $181 million and 15.1%, respectively. Income tax expense and the effective income tax rate during the nine months ended September 30, 2012 were primarily driven by the geographic distribution of the Company’s pre-tax net income between its various taxable and non-taxable jurisdictions. Specifically, the income tax expense and the effective income tax rate included a relatively even distribution of the Company’s pre-tax net income between its various jurisdictions. The Company’s pre-tax net income recorded in non-taxable jurisdictions and jurisdictions with comparatively lower tax rates was driven by the absence of catastrophe losses and net realized and unrealized investment gains. The Company’s pre-tax net income recorded in jurisdictions with comparatively higher tax rates was driven by net favorable prior year loss development and net realized and unrealized investment gains.

Financial Condition, Liquidity and Capital Resources

The Company purchased, as part of its acquisition of Paris Re, an investment portfolio and a funds held – directly managed account.

The discussion of the segregated investment portfolio underlying the funds held – directly managed account is included separately in Funds Held – Directly Managed below.

Investments

Investment philosophy

The Company employs a prudent investment philosophy. It maintains a high quality, well balanced and liquid portfolio having the dual objectives of optimizing current investment income and achieving capital appreciation. The Company’s invested assets are comprised of total investments, cash and cash equivalents and accrued investment income. From a risk management perspective, the Company allocates its invested assets into two categories: liability funds and capital funds. For additional information on the Company’s capital and liability funds, see Financial Condition, Liquidity and Capital Resources—Investments in Item 7 Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

The Company’s total invested assets at September 30, 2013 and December 31, 2012 were split between liability and capital funds as follows (in millions of U.S. dollars):


	September 30, 2013		% of Total Invested Assets			December 31, 2012		% of Total Invested Assets
Liability funds	$	10,331		59	%	$	10,723		59	%
Capital funds		7,184		41			7,453		41

Total invested assets	$	17,515		100	%	$	18,176		100	%

The decrease of $661 million in total invested assets at September 30, 2013 compared to December 31, 2012 was primarily related to a decrease in total investments and a decrease in investments underlying the funds held – directly managed account, which was partially offset by an increase in cash. The decrease in total investments was primarily related to the sale and maturity of fixed maturities to fund the Company’s share repurchases and dividends and increases in U.S. and European risk-free rates. The decrease in the funds held – directly managed account, was primarily driven by the run-off of the related loss reserves and increasing U.S. and European risk-free interest rates.

The liability funds were comprised of cash and cash equivalents and high quality fixed income securities. The decrease in the liability funds at September 30, 2013 compared to December 31, 2012 was primarily driven by an increase in net reinsurance assets related to business written during 2013.

The capital funds were generally comprised of accrued investment income, investment grade and below investment grade fixed maturity securities, preferred and common stocks, private placement equity and bond investments, emerging markets and high-yield fixed income securities and certain other specialty asset classes. The decrease in the capital funds at September 30, 2013 compared to December 31, 2012 was primarily driven by the decrease in total invested assets, as described above. At September 30, 2013, approximately 61% of the capital funds were invested in cash and cash equivalents and investment grade fixed income securities.

Overview

Total investments and cash were $16.7 billion at September 30, 2013 compared to $17.1 billion at December 31, 2012. The major factors contributing to the decrease in the nine months ended September 30, 2013 were:

•

a net decrease of $537 million, due to the repurchase of common shares of $594 million under the Company’s share repurchase program, partially offset by the issuance of common shares under the Company’s employee equity plans of $57 million;

•

net realized and unrealized losses related to the investment portfolio of $242 million primarily resulting from a decrease in the fixed maturity and short-term investment portfolios of $357 million reflecting increasing U.S. and European risk-free interest rates, which was partially offset by an increase in the equity portfolio of $61 million and an increase in other invested assets of $56 million driven by gains on treasury note futures (see discussion related to duration below);

•

dividend payments on common and preferred shares totaling $152 million;

•

a net payment of $48 million related to the redemption of Series C preferred shares of $290 million which was partially offset by proceeds related to the issuance of the Series F preferred shares of $242 million, after underwriting discounts and commissions (see Note 5 to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this report and Contractual Obligations, Commitments and Contingencies and Shareholders’ Equity and Capital Resources Management below); and

•

various other factors which net to approximately $127 million, the largest being the amortization of net premium on investments; partially offset by

•

net cash provided by operating activities of $584 million; and

•

an increase in net payables for securities sold of $86 million.

Trading securities

The following discussion relates to the composition of the Company’s trading securities, the Company’s other invested assets and the investments underlying the funds held – directly managed account are discussed separately below. Trading securities are carried at fair value with changes in fair value included in net realized and unrealized investment gains and losses in the Condensed Consolidated Statements of Operations.

At September 30, 2013, approximately 95% of the Company’s fixed maturity and short-term investments, which includes fixed income type mutual funds, were publicly traded and approximately 90% were rated investment grade (BBB- or higher) by Standard & Poor’s (or estimated equivalent).

The average credit quality, the average yield to maturity and the expected average duration of the Company’s fixed maturities and short-term investments, which includes fixed income type mutual funds, at September 30, 2013 and December 31, 2012 were as follows:


	September 30, 2013	December 31, 2012
Average credit quality	A	A
Average yield to maturity	2.5%	2.0%
Expected average duration	2.7 years	2.7 years

The increase in the average yield to maturity on fixed maturities, short-term investments and cash and cash equivalents at September 30, 2013 compared to December 31, 2012, was primarily due to increases in U.S. and European risk-free interest rates.

For the purposes of managing portfolio duration, the Company uses exchange traded treasury note futures. The use of treasury note futures reduced the expected average duration of the investment portfolio from 4.0 years to 2.7 years at September 30, 2013, and reflects the Company’s decision to continue to hedge against potential further rises in risk-free interest rates.

The Company’s investment portfolio generated a total accounting return (calculated based on the carrying value of all investments in local currency) of 0.9% and 0.8% for the three months and nine months ended September 30, 2013, respectively, compared to 2.4% and 5.6%, respectively, in the same periods of 2012. The total accounting return in the three months ended September 30, 2013 was mainly due to narrowing credit spreads and improvements in equity markets, which were partially offset by increases in U.S. and European risk-free interest rates, while the same period of 2012 was primarily impacted by narrowing credit spreads and improvements in equity markets. The total accounting return in the nine months ended September 30, 2013 was mainly due to improvements in equity markets and narrowing credit spreads and partially offset by increases in U.S. and European risk-free interest rates, while the same period of 2012 was primarily impacted by narrowing credit spreads, improvements in equity markets and modest declines in U.S. and European risk-free interest rates.

The cost, fair value and credit ratings of the Company’s fixed maturities, short-term investments and equities classified as trading at September 30, 2013 were as follows (in millions of U.S. dollars):

The decrease of $0.7 billion in the fair value of the Company’s fixed maturities from $14.4 billion at December 31, 2012 to $13.7 billion at September 30, 2013, primarily reflects the sale and maturity of fixed maturities to fund the Company’s share repurchases and dividend payments and increases in U.S. and European risk-free interest rates. At September 30, 2013, there has been a shift in the distribution of the fixed maturity portfolio compared to December 31, 2012. Specifically, the Company has decreased its corporate bonds and residential mortgage-backed securities, and increased its U.S. government and asset-backed securities.

At September 30, 2013, 84% of this category was rated AA with the remaining 16%, although not specifically rated, generally considered to have a credit quality equivalent to AA+ corporate issues.

The U.S. states, territories and municipalities category includes obligations of U.S. states, territories, or counties.

The non-U.S. sovereign government, supranational and government related category includes obligations of non-U.S. sovereign governments, political subdivisions, agencies and supranational debt.

GSEs, or government sponsored enterprises, includes securities that are issued by U.S. government agencies, such as Freddie Mac and Fannie Mae.

Residential mortgage-backed securities includes U.S. residential mortgage-backed securities, which generally have a low risk of default and carry the implicit backing of the U.S. government. The issuers of these securities are U.S. government agencies or GSEs, which set standards on the mortgages before accepting them into the program. Although these U.S. government backed securities do not carry a formal rating, they are generally considered to have a credit quality equivalent to or greater than AA+ corporate issues. They are considered prime mortgages and the major risk is uncertainty of the timing of prepayments. While there have been market concerns regarding sub-prime mortgages, the Company did not have direct exposure to these types of securities in its own portfolio at September 30, 2013, other than $22 million of investments in distressed asset vehicles (included in Other invested assets). At September 30, 2013, the Company’s U.S. residential mortgage-backed securities included approximately $2 million (less than 1% of U.S. residential mortgage-backed securities) of collateralized mortgage obligations, where the Company deemed the entry point and price of the investment to be attractive.

At September 30, 2013, insurance-linked securities include a longevity swap for which the notional amount is not reflective of the overall potential exposure of the swap. As such, the Company has included the probable maximum loss under the swap within the net notional exposure as an approximation of the notional amount.

At September 30, 2013, the Company’s strategic investments included $209 million of investments classified in Other invested assets. These strategic investments include investments in non-publicly traded companies, private placement equity and bond investments, notes and loans receivable and other specialty asset classes, and the investments in distressed asset vehicles comprised of sub-prime mortgages, which were discussed above in the residential mortgaged-backed securities category of Investments–Trading Securities. In addition to the Company’s strategic investments that are classified in Other invested assets, strategic investments of $36 million are recorded in equities and other assets at September 30, 2013.

At September 30, 2013, the Company’s principal finance activities included $107 million of investments classified in Other invested assets, which were comprised primarily of asset-backed securities, notes and loans receivable, annuities and residuals and private placement equity investments, which were partially offset by the combined fair value of total return, interest rate and certain credit default swaps related to principal finance activities.

For total return swaps within the principal finance portfolio, the Company uses internal valuation models to estimate the fair value of these derivatives and develops assumptions that require significant judgment, such as the timing of future cash flows, credit spreads and the general level of interest rates. For interest rate swaps, the Company uses externally modeled quoted prices that use observable market inputs. At September 30, 2013, all of the Company’s principal finance total return and interest rate swap portfolio was related to tax advantaged real estate income. For credit default swaps within the principal finance portfolio, the Company uses externally modeled quoted prices that use observable market inputs to estimate the fair value.

The Company also utilizes credit default swaps to mitigate the risk associated with certain of its underwriting obligations, most notably in the credit/surety line, to replicate investment positions or to manage market exposures and to reduce the credit risk for specific fixed maturities in its investment portfolio. The counterparties to the Company’s credit default swaps are all investment grade financial institutions rated A- or better by Standard & Poor’s at September 30, 2013. The Company uses externally modeled quoted prices that use observable market inputs to estimate the fair value of these swaps.

The Company has entered into various weather derivatives and longevity total return swaps for which the underlying risks reference parametric weather risks and longevity risks, respectively. The Company uses internal valuation models to estimate the fair value of these derivatives and develops assumptions that require significant judgment, except for exchange traded weather derivatives. In determining the fair value of exchange traded weather derivatives, the Company uses quoted market prices.

The Company uses exchange traded treasury note futures for the purposes of managing portfolio duration. The Company also uses equity futures to replicate equity investment positions.

The Company utilizes foreign exchange forward contracts and foreign currency option contracts as part of its overall currency risk management and investment strategies.

The Company utilizes to-be-announced mortgage-backed securities (TBAs) as part of its overall investment strategy and to enhance investment performance. TBAs represent commitments to purchase future issuances of U.S. government agency mortgage backed securities. For the period between purchase of a TBA and issuance of the underlying security, the Company’s position is accounted for as a derivative. The Company’s policy is to maintain designated cash balances at least equal to the amount of outstanding TBA purchases.

At September 30, 2013, the Company’s other invested assets did not include any exposure to peripheral EU countries (Portugal, Italy, Ireland, Greece and Spain) and included direct exposure to mutual fund investments in other EU countries of less than $3 million. The counterparties to the Company’s credit default swaps, foreign exchange forward contracts and foreign currency option contracts include European finance sector institutions rated A- or better by Standard & Poor’s and the Company manages its exposure to individual institutions. The Company also has exposure to the euro related to the utilization of foreign exchange forward contracts and other derivative financial instruments in its hedging strategy (see Quantitative and Qualitative Disclosures About Market Risk—Foreign Currency Risk in Item 3 below).

Funds Held – Directly Managed

For a discussion of the funds held – directly managed account and the related quota share retrocession agreement, see Business—Reserves—Reserve Agreement in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. See also Quantitative and Qualitative Disclosures about Market Risk—Counterparty Credit Risk in Item 7A of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 and in Item 3 below. The composition of the investments underlying the funds held – directly managed account at September 30, 2013 is discussed below.

At September 30, 2013, approximately 98% of the fixed income investments underlying the funds held – directly managed account were publicly traded and substantially all (more than 99%) were rated investment grade (BBB- or higher) by Standard & Poor’s (or estimated equivalent).

The average credit quality, the average yield to maturity and the expected average duration of the fixed maturities and short-term investments underlying the funds held – directly managed account at September 30, 2013 and December 31, 2012 were as follows:


	September 30, 2013			December 31, 2012
Average credit quality		AA			AA
Average yield to maturity		1.2	%		1.0	%
Expected average duration		3.1 years			3.0 years

The increase in the average yield to maturity on fixed maturities, short-term investments and cash and cash equivalents underlying the funds held – directly managed account at September 30, 2013 compared to December 31, 2012, was primarily due to increases in U.S. and European risk-free interest rates. The average credit quality and the expected average duration of the fixed maturities underlying the funds held – directly managed account at September 30, 2013 were comparable to December 31, 2012.

The cost, fair value and credit rating of the investments underlying the funds held – directly managed account at September 30, 2013 were as follows (in millions of U.S. dollars):

The decrease in the fair value of the investment portfolio underlying the funds held – directly managed account from $833 million at December 31, 2012 to $638 million at September 30, 2013 was primarily related the run-off of loss reserves associated with this account and increases in U.S. and European risk-free interest rates.

The U.S. government category includes U.S. treasuries which are not rated, however, they are generally considered to have a credit quality equivalent to or greater than AA+ corporate issues.

The U.S. government sponsored enterprises (GSEs) category includes securities that carry the implicit backing of the U.S. government and securities issued by U.S. government agencies (such as Freddie Mac and Fannie Mae). At September 30, 2013, 82% of this category was rated AA with the remaining 18%, although not specifically rated, generally considered to have a credit quality equivalent to AA+ corporate issues.

The non-U.S. sovereign government, supranational and government related category includes obligations of non-U.S. sovereign governments, political subdivisions, agencies and supranational debt. The fair value and credit ratings of non-U.S. sovereign government, supranational and government related obligations underlying the funds held – directly managed account at September 30, 2013 were as follows (in millions of U.S. dollars):

At September 30, 2013, the investments underlying the funds held – directly managed account included less than $1 million of securities issued by peripheral European Union (EU) sovereign governments (Portugal, Italy, Ireland, Greece and Spain).

Corporate bonds underlying the funds held – directly managed account are comprised of obligations of U.S. and foreign corporations. The fair value of corporate bonds issued by U.S. and foreign corporations underlying funds held – directly managed account by economic sector at September 30, 2013 were as follows (in millions of U.S. dollars):

At September 30, 2013, other than the U.S., France, the U.K. and the Netherlands, which accounted for 39%, 16%, 12% and 11% respectively, no other country accounted for more than 10% of the Company’s corporate bonds underlying the funds held – directly managed account.

At September 30, 2013, the ten largest issuers accounted for 31% of the corporate bonds underlying the funds held – directly managed account and no single issuer accounted for more than 4% of corporate bonds underlying the funds held – directly managed account (or more than 2% of the investments and cash underlying the funds held – directly managed account). At September 30, 2013, all of the finance sector corporate bonds held were rated investment grade (BBB- or higher) by Standard & Poor’s (or estimated equivalent) and 98% were rated A- or better.

At September 30, 2013, the fair value of corporate bonds underlying the funds held – directly managed account that were issued by companies in the European Union were as follows (in millions of U.S. dollars):

European Exposures

For a discussion of the Company’s management of the recent uncertainties related to European sovereign debt exposures, the uncertainties surrounding Europe in general and the Company’s responses to them, see Financial Condition, Liquidity and Capital Resources—Investments—European exposures in Item 7 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

There have not been any significant changes to the Company’s guidelines adopted in response to the European crisis during the nine months ended September 30, 2013.

The Company’s exposures to European sovereign governments and other European related investment risks are discussed above within each category of the Company’s investment portfolio and the investments underlying the funds held – directly managed account. In addition, the Company’s other investment and derivative exposures to European counterparties are discussed in Other Invested Assets above. See Risk Factors in Item 1A of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for further discussion of the Company’s exposure to the European sovereign debt crisis.

Funds Held by Reinsured Companies (Cedants)

In addition to the funds held – directly managed account described above, the Company writes certain business on a funds held basis. Funds held by reinsured companies at September 30, 2013 have not changed significantly since December 31, 2012. See Funds Held by Reinsured Companies (Cedants) in Item 7 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Unpaid Losses and Loss Expenses

The Company establishes loss reserves to cover the estimated liability for the payment of all losses and loss expenses incurred with respect to premiums earned on the contracts that the Company writes. Loss reserves do not represent an exact calculation of the liability. Estimates of ultimate liabilities are contingent on many future events and the eventual outcome of these events may be different from the assumptions underlying the reserve estimates. The Company believes that the recorded unpaid losses and loss expenses represent Management’s best estimate of the cost to settle the ultimate liabilities based on information available at September 30, 2013.

At September 30, 2013 and December 31, 2012, the Company recorded gross and net Non-life reserves for unpaid losses and loss expenses as follows (in millions of U.S. dollars):


	September 30, 2013		December 31, 2012
Gross Non-life reserves for unpaid losses and loss expenses	$	10,565	$	10,709
Net Non-life reserves for unpaid losses and loss expenses		10,279		10,418
Net reserves guaranteed by Colisée Re		749		857

The net Non-life reserves for unpaid losses and loss expenses at September 30, 2013 and December 31, 2012 include $749 million and $857 million of reserves guaranteed by Colisée Re (see Item 1 of Part I and Note 8 to Consolidated Financial Statements included in Item 8 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of the Reserve Agreement).

The following table provides a reconciliation of the net Non-life reserves for unpaid losses and loss expenses for the nine months ended September 30, 2013 (in millions of U.S. dollars):


	For the nine months ended September 30, 2013
Net liability at December 31, 2012	$	10,418
Net incurred losses related to:
Current year		2,269
Prior years		(548	)

		1,721
Change in Paris Re Reserve Agreement		(46	)
Net paid losses		(1,812	)
Effects of foreign exchange rate changes		(2	)

Net liability at September 30, 2013	$	10,279

The decrease in net Non-life reserves for unpaid losses and loss expenses from $10,418 million at December 31, 2012 to $10,279 million at September 30, 2013 primarily reflects the payment of losses, which was partially offset by net losses incurred during the nine months ended September 30, 2013.

See Critical Accounting Policies and Estimates—Losses and Loss Expenses and Life Policy Benefits and Results by Segment above for a discussion of losses and loss expenses and prior years’ reserve developments. See also Business—Reserves in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of the impact of foreign exchange on unpaid losses and loss expenses.

Policy Benefits for Life and Annuity Contracts

At September 30, 2013 and December 31, 2012, the Company recorded gross and net policy benefits for life and annuity contracts as follows (in millions of U.S. dollars):


	September 30, 2013		December 31, 2012
Gross policy benefits for life and annuity contracts	$	1,909	$	1,813
Net policy benefits for life and annuity contracts		1,902		1,793

The following table provides a reconciliation of the net policy benefits for life and annuity contracts for the nine months ended September 30, 2013 (in millions of U.S. dollars):


	For the nine months ended September 30, 2013
Net liability at December 31, 2012	$	1,793
Net incurred losses related to:
Current year		591
Prior years		(33	)

		558
Net paid losses		(465	)
Effects of foreign exchange rate changes		16

Net liability at September 30, 2013	$	1,902

The increase in net policy benefits for life and annuity contracts from $1,793 million at December 31, 2012 to $1,902 million at September 30, 2013 is primarily due to incurred losses, which were partially offset by paid losses.

See Critical Accounting Policies and Estimates—Losses and Loss Expenses and Life Policy Benefits and Results by Segment above for a discussion of life policy benefits and prior years’ reserve developments. See also Business—Reserves in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Reinsurance Recoverable on Paid and Unpaid Losses

The Company has exposure to credit risk related to reinsurance recoverable on paid and unpaid losses. See Note 9 to Consolidated Financial Statements and Quantitative and Qualitative Disclosures about Market Risk—Counterparty Credit Risk in Item 7A of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of the Company’s risk related to reinsurance recoverable on paid and unpaid losses and the Company’s process to evaluate the financial condition of its reinsurers.

Contractual Obligations, Commitments and Contingencies

In the normal course of its business, the Company is a party to a variety of contractual obligations, which are discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. These contractual obligations are considered by the Company when assessing its liquidity requirements and the Company is confident in its ability to meet all of its obligations.

Other than the items discussed below, the Company’s contractual obligations at September 30, 2013 have not changed materially compared to December 31, 2012.

On February 14, 2013, the Company issued 5.875% Series F non-cumulative redeemable preferred shares (Series F preferred shares) for a total consideration of $242 million after underwriting discounts, commissions and other related expenses. The Company has a non-cumulative dividend commitment of $14.7 million per annum in relation to the Series F preferred shares. On or after March 1, 2018, the Company may redeem the Series F preferred shares at the aggregate liquidation value of $250 million. See Shareholders’ Equity and Capital Resources Management below for more details related to the Series F preferred shares.

On March 18, 2013, the Company redeemed the 6.75% Series C cumulative redeemable preferred shares (Series C preferred shares) for the aggregate liquidation value of $290 million plus accrued dividends.

Tax developments

As part of the 2014 Budget proposals, the French government has proposed tax legislation changes. This proposal would temporarily increase the corporation income tax rate from 36% to 38% and could limit the deductibility of interest payments to non-French affiliates. These changes may be effective retroactively to January 1, 2013. These proposals have not been enacted into the French tax code and, therefore, may be modified during the French legislative process. It is expected that the 2014 Budget proposals, including any tax proposals, will be finalized and enacted into law in December 2013. The Company is in the process of monitoring and evaluating the impact of these developments on its operations. The Company may incur a charge in the fourth quarter of 2013 relating to these tax proposals, which may be material, when these proposed tax changes are finalized and enacted into the French tax code. The Company is not currently able to determine a reasonable estimate of the amount of the charge given the uncertainty that exists related to these proposals.

Shareholders’ Equity and Capital Resources Management

Shareholders’ equity attributable to PartnerRe Ltd. common shareholders’ was $6.6 billion at September 30, 2013, a 5% decrease compared to $6.9 billion at December 31, 2012. The major factors contributing to the decrease in shareholders’ equity during the nine months ended September 30, 2013 were:

•

dividend payments of $152 million related to both the Company’s common and preferred shares; and

•

a net decrease of $48 million related to the redemption of Series C preferred shares of $290 million which was partially offset by proceeds of $242 million, after underwriting discounts, commissions and other expenses, related to the issuance of the Series F preferred shares (see Note 5 to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this report and Contractual Obligations, Commitments and Contingencies and Shareholders’ Equity and Capital Resources Management above); partially offset by

•

comprehensive income of $375 million, which was primarily related to net income of $392 million and was partially offset by the change in the currency translation adjustment of $17 million.

See Results of Operations and Review of Net Income above for a discussion of the Company’s net income for the nine months ended September 30, 2013.

As part of its long-term strategy, the Company will continue to actively manage capital resources to support its operations throughout the reinsurance cycle and for the benefit of its shareholders, subject to the ability to maintain strong ratings from the major rating agencies and the unquestioned ability to pay claims as they arise. Generally, the Company seeks to increase its capital when its current capital position is not sufficient to support the volume of attractive business opportunities available. Conversely, the Company will seek to reduce its capital, through the payment of dividends on its common shares or stock repurchases, when available business opportunities are insufficient or unattractive to fully utilize the Company’s capital at adequate returns. The Company may also seek to reduce or restructure its capital through the repayment or purchase of debt obligations, or increase or restructure its capital through the issuance of debt, when opportunities arise.

Management uses certain key measures to evaluate its financial performance and the overall growth in value generated for the Company’s common shareholders. For a discussion related to growth in Diluted Tangible Book Value per Share plus accumulated dividends see Key Financial Measures above.

The table below sets forth the capital structure of the Company at September 30, 2013 and December 31, 2012 (in millions of U.S. dollars):


	September 30, 2013				December 31, 2012
Capital Structure:

The decrease in total capital during the nine months ended September 30, 2013 was related to the same factors describing shareholders’ equity above.

Indebtedness

There was no change in the Company’s indebtedness at September 30, 2013 compared to December 31, 2012 and the Company did not enter into any short-term borrowing arrangements during the three months ended September 30, 2013. See Note 10 to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of the Company’s indebtedness.

Shareholders’ Equity

Share Repurchases

In September 2013, the Company’s Board of Directors approved a new share repurchase authorization up to a total of 6 million common shares, which replaced the prior authorization of 6 million common shares approved in March 2013. Unless terminated earlier by resolution of the Company’s Board of Directors, the program will expire when the Company has repurchased all shares authorized for repurchase thereunder. At September 30, 2013, the Company had approximately 6.0 million common shares remaining under its current share repurchase authorization and approximately 33.2 million common shares were held in treasury and are available for reissuance.

During the nine months ended September 30, 2013, the Company repurchased under its authorized share repurchase program, 6.6 million of its common shares at a total cost of $594 million, representing an average cost of $89.41 per share. These shares were repurchased at a discount to diluted book value per share at December 31, 2012 of approximately 11%.

Subsequently, during the period from October 1, 2013 to October 31, 2013, the Company repurchased 0.1 million common shares at a total cost of $8 million, representing an average cost of $91.77 per share. Following these repurchases, the Company had approximately 5.9 million common shares remaining under its current share repurchase authorization and approximately 33.3 million common shares are held in treasury and are available for reissuance. See Unregistered Sales of Equity Securities and Use of Proceeds in Item 2 of Part II of this report.

Redeemable Preferred Shares

On February 14, 2013, the Company issued 10 million of 5.875% Series F non-cumulative redeemable preferred shares for a total consideration of $242 million after underwriting discounts, commissions and other related expenses. The Series F preferred shares have an aggregate liquidation value of $250 million. On or after March 1, 2018, the Company may redeem the Series F preferred shares in whole at any time, or in part from time to time, at $25.00 per share, plus an amount equal to the portion of the quarterly dividend attributable to the then-current dividend period to, but excluding, the redemption date. The Company may also redeem the Series F preferred shares at any time upon the occurrence of a certain “capital disqualification event” or certain changes in tax law. Dividends on the Series F preferred shares are non-cumulative and are payable quarterly. In the event of liquidation of the Company, the Series F preferred shares rank on parity with each of the other series of preferred shares and would rank senior to the common shares, and holders thereof would receive a distribution of $25.00 per share, or the aggregate liquidation value, plus declared but unpaid dividends, if any. See Note 5 to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this report and Contractual Obligations, Commitments and Contingencies and Shareholders’ Equity and Capital Resources Management above.

On March 18, 2013, the Company redeemed all of its Series C preferred shares for the aggregate liquidation value of $290 million plus accrued dividends.

See also Note 11 to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of the Company’s other series of preferred shares.

Liquidity

Liquidity is a measure of the Company’s ability to access sufficient cash flows to meet the short-term and long-term cash requirements of its business operations. Management believes that its significant cash flows from operations and high quality liquid investment portfolio will provide sufficient liquidity for the foreseeable future. At September 30, 2013 and December 31, 2012, cash and cash equivalents were $1.6 billion and $1.1 billion, respectively. The increase in cash and cash equivalents was primarily due to cash provided by the Company’s investing and operating activities, which was partially utilized to fund the Company’s share repurchases and dividend payments.

Cash flows from operations increased to $584 million for the nine months ended September 30, 2013 from $469 million in the same period of 2012. The increase was primarily due to higher underwriting cash flows, which were related to a higher level of premium receipts driven by the increase in gross premiums written and a lower level of loss payments in the nine months ended September 30, 2013 compared to the same period of 2012. This increase in cash flows from operations was partially offset by lower investment income.

Net cash provided by investing activities was $584 million in the nine months ended September 30, 2013 compared to net cash used by investing activities of $11 million during the same period of 2012. The net cash provided by investing activities in the nine months ended September 30, 2013 reflects the sale and maturity of investments to fund financing activities, as described below.

Net cash used in financing activities was $736 million in the nine months ended September 30, 2013 compared to $458 million in the same period of 2012. Net cash used in financing activities in the nine months ended September 30, 2013 was primarily related to the Company’s share repurchases, the redemption of the Series C preferred shares and dividend payments on common and preferred shares, which were partially offset by proceeds from the issuance of the Series F preferred shares. Net cash used in financing activities in the same period of 2012 was related to share repurchases and dividend payments on common and preferred shares.

The Company believes that annual positive cash flows from operating activities will be sufficient to cover claims payments, absent a series of additional large catastrophic loss activity. In the event that paid losses accelerate beyond the ability to fund such payments from operating cash flows, the Company would use its cash balances available, liquidate a portion of its high quality and liquid investment portfolio or borrow under the Company’s revolving line of credit (see Credit Agreements below) or access certain uncommitted facilities. As discussed in Investments above, the Company’s investments and cash totaled $16.7 billion at September 30, 2013, the main components of which were investment grade fixed maturities, short-term investments and cash and cash equivalents totaling $14.1 billion.

Financial strength ratings and senior unsecured debt ratings represent the opinions of rating agencies on the Company’s capacity to meet its obligations. There was no change in the Company’s current financial strength ratings at September 30, 2013 compared to December 31, 2012. See also Shareholders’ Equity and Capital Resources Management—Liquidity in Item 7 of Part II of the Company’s Annual report on Form 10-K for the year ended December 31, 2012.

Credit Agreements

Other than the expiration of the credit facility discussed above, the Company’s credit facilities have not changed significantly since December 31, 2012. See Credit Agreements in Item 7 of Part II and Note 18 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for further information related to the credit facilities available to the Company.

Currency

See Results of Operations and Review of Net Income above for a discussion of the impact of foreign exchange and net foreign exchange gains and losses during the nine months ended September 30, 2013 and 2012.

The foreign exchange gain or loss resulting from the translation of the Company’s subsidiaries’ and branches’ financial statements (expressed in euro or Canadian dollar functional currency) into U.S. dollars is classified in the currency translation adjustment account, which is a component of accumulated other comprehensive income or loss in shareholders’ equity. The currency translation adjustment account decreased by $17 million during the nine months ended September 30, 2013 due to the translation of the Company’s subsidiaries and branches, whose functional currencies are the Canadian dollar and the euro.

The following table provides a reconciliation of the currency translation adjustment for the nine months ended September 30, 2013 (in millions of U.S. dollars):


	For the nine months ended September 30, 2013
Currency translation adjustment at December 31, 2012	$	33
Change in currency translation adjustment included in accumulated other comprehensive loss		(17	)

Currency translation adjustment at September 30, 2013	$	16

From time to time, the Company enters into net investment hedges. At September 30, 2013, there were no outstanding foreign exchange contracts hedging the Company’s net investment exposure.

See Quantitative and Qualitative Disclosures About Market Risk—Foreign Currency Risk in Item 3 of Part I below for a discussion of the Company’s risk related to changes in foreign currency movements.

Management believes that the Company is principally exposed to five types of market related risk: interest rate risk, credit spread risk, foreign currency risk, counterparty credit risk and equity price risk. How these risks relate to the Company, and the process used to manage them, is discussed in Item 7A of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The following discussion of market risks at September 30, 2013 focuses only on material changes from December 31, 2012 in the Company’s market risk exposures, or how those exposures are managed.

Interest Rate Risk

The Company’s fixed maturity portfolio and the fixed maturity securities in the investment portfolio underlying the funds held – directly managed account are exposed to interest rate risk. Fluctuations in interest rates have a direct impact on the market valuation of these securities. The Company manages interest rate risk on liability funds by constructing bond portfolios in which the economic impact of a general interest rate shift is comparable to the impact on the related liabilities. The Company believes that this process of matching the duration mitigates the overall interest rate risk on an economic basis. The Company manages the exposure to interest rate volatility on capital funds by choosing a duration profile that it believes will optimize the risk-reward relationship. For additional information on liability funds and capital funds, see Financial Condition, Liquidity and Capital Resources in Item 7 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

At September 30, 2013, the Company estimates that the hypothetical case of an immediate 100 basis points or 200 basis points parallel shift in global bond curves would result in a change in the fair value of investments exposed to interest rate risk, the fair value of funds held – directly managed account exposed to interest rate risk, total invested assets, and shareholders’ equity as follows (in millions of U.S. dollars):


	-200 Basis Points		% Change			-100 Basis Points		% Change			September 30, 2013		+100 Basis Points		% Change			+200 Basis Points		% Change
Fair value of investments exposed to interest rate risk⁽¹⁾⁽²⁾	$	15,936		6	%	$	15,517		3	%	$	15,098	$	14,679		(3	)%	$	14,260		(6	)%
Fair value of funds held – directly managed account exposed to interest rate risk⁽²⁾		696		6			676		3			656		636		(3	)		616		(6	)
Total invested assets⁽³⁾		18,393		5			17,954		3			17,515		17,076		(3	)		16,637		(5	)
Shareholders’ equity		7,502		13			7,063		7			6,624		6,185		(7	)		5,746		(13	)

(1)

Includes certain other invested assets, certain cash and cash equivalents and funds holding fixed income securities.

(2)

Excludes accrued interest.

(3)

Includes total investments, cash and cash equivalents, the investment portfolio underlying the funds held – directly managed account and accrued interest.

The changes do not take into account any potential mitigating impact from the equity market, taxes or the corresponding change in the economic value of the Company’s reinsurance liabilities, which, as noted above, would substantially offset the economic impact on invested assets, although the offset would not be reflected in the Condensed Consolidated Balance Sheets.

As discussed above, the Company strives to match the foreign currency exposure in its fixed income portfolio to its multicurrency liabilities. The Company believes that this matching process creates a diversification benefit. Consequently, the exact market value effect of a change in interest rates will depend on which countries experience interest rate changes and the foreign currency mix of the Company’s fixed maturity portfolio at the time of the interest rate changes. See Foreign Currency Risk below.

The impact of an immediate change in interest rates on the fair value of investments and funds held – directly managed exposed to interest rate risk, the Company’s total invested assets and shareholders’ equity, in both absolute terms and as a percentage of total invested assets and shareholders’ equity, has not changed significantly at September 30, 2013 compared to December 31, 2012.

Other than the changes related to the redemption of the Series C preferred shares and the issuance of the Series F preferred shares, the fair value of the Company’s preferred securities did not change significantly at September 30, 2013, compared to December 31, 2012. See Shareholders’ Equity and Capital Resources Management—Redeemable Preferred Shares above for a discussion of the issuance of Series F non-cumulative preferred shares in February 2013 and the redemption of the Series C preferred shares in March 2013.

The fair value of the Company’s outstanding debt obligations decreased modestly at September 30, 2013 compared to December 31, 2012, primarily due to rising U.S. risk-free rates.

For additional information related to the Company’s debt obligations and preferred securities, see Item 7A of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. For additional information related to the Company’s debt obligations also see Note 3 to the Condensed Consolidated Financial Statements in Item 1 of Part I of this report.

Credit Spread Risk

The Company’s fixed maturity portfolio and the fixed maturity securities in the investment portfolio underlying the funds held – directly managed account are exposed to credit spread risk. Fluctuations in market credit spreads have a direct impact on the market valuation of these securities. The Company manages credit spread risk by the selection of securities within its fixed maturity portfolio. Changes in credit spreads directly affect the market value of certain fixed maturity securities, but do not necessarily result in a change in the future expected cash flows associated with holding individual securities. Other factors, including liquidity, supply and demand, and changing risk preferences of investors, may affect market credit spreads without any change in the underlying credit quality of the security.

At September 30, 2013, the Company estimates that the hypothetical case of an immediate 100 basis points or 200 basis points parallel shift in global credit spreads would result in a change in the fair value of investments and the fair value of funds held – directly managed account exposed to credit spread risk, total invested assets and shareholders’ equity as follows (in millions of U.S. dollars):


	-200 Basis Points		% Change			-100 Basis Points		% Change			September 30, 2013		+100 Basis Points		% Change			+200 Basis Points		% Change
Fair value of investments exposed to credit spread risk⁽¹⁾⁽²⁾	$	15,956		6	%	$	15,527		3	%	$	15,098	$	14,669		(3	)%	$	14,240		(6	)%
Fair value of funds held – directly managed account exposed to credit spread risk⁽²⁾		674		3			665		1			656		647		(1	)		638		(3	)
Total invested assets⁽³⁾		18,391		5			17,953		3			17,515		17,077		(3	)		16,639		(5	)
Shareholders’ equity		7,500		13			7,062		7			6,624		6,186		(7	)		5,748		(13	)

(1)

Includes certain other invested assets, certain cash and cash equivalents and funds holding fixed income securities.

(2)

Excludes accrued interest.

(3)

Includes total investments, cash and cash equivalents, the investment portfolio underlying the funds held – directly managed account and accrued interest.

The changes above also do not take into account any potential mitigating impact from the equity market, taxes, and the change in the economic value of the Company’s reinsurance liabilities, which may offset the economic impact on invested assets.

The impact of an immediate change in credit spreads on the fair value of investments and funds held – directly managed exposed to credit spread risk, the Company’s total invested assets and shareholders’ equity, in both absolute terms and as a percentage of total invested assets and shareholders’ equity, has not changed significantly at September 30, 2013 compared to December 31, 2012.

Foreign Currency Risk

Through its multinational reinsurance operations, the Company conducts business in a variety of non-U.S. currencies, with the principal exposures being the euro, Canadian dollar, British pound, New Zealand dollar, and Australian dollar. As the Company’s reporting currency is the U.S. dollar, foreign exchange rate fluctuations may materially impact the Company’s Condensed Consolidated Financial Statements.

The table below summarizes the Company’s gross and net exposure in its Condensed Consolidated Balance Sheet at September 30, 2013 to foreign currency as well as the associated foreign currency derivatives the Company has entered into to manage this exposure (in millions of U.S. dollars):


	euro			CAD			GBP			NZD			AUD			Other			Total⁽¹⁾
Total assets	$	4,462		$	1,187		$	1,620		$	139		$	127		$	727		$	8,262
Total liabilities		(4,567	)		(694	)		(1,021	)		(246	)		(209	)		(1,384	)		(8,121	)

Total gross foreign currency exposure		(105	)		493			599			(107	)		(82	)		(657	)		141
Total derivative amount		152			(17	)		(532	)		114			106			696			519

Net foreign currency exposure		47			476			67			7			24			39			660

(1)

As the U.S. dollar is the Company’s reporting currency, there is no currency risk attached to the U.S. dollar and it is excluded from this table. The U.S. dollar accounted for the difference between the Company’s total foreign currency exposure in this table and the total assets and total liabilities in the Company’s Condensed Consolidated Balance Sheet at September 30, 2013.

The above numbers include the Company’s investment in PartnerRe Holdings Europe Limited, whose functional currency is the euro, and certain of its subsidiaries and branches, whose functional currencies are the euro or Canadian dollar.

At September 30, 2013, assuming all other variables remain constant and disregarding any tax effects, a change in the U.S. dollar of 10% or 20% relative to the other currencies held by the Company would result in a change in the Company’s net assets of $66 million and $132 million, respectively, inclusive of the effect of foreign exchange forward contracts and other derivative financial instruments.

Counterparty Credit Risk

The Company has exposure to credit risk primarily as a holder of fixed maturity securities. The Company controls this exposure by emphasizing investment grade credit quality in the fixed maturity securities it purchases. At September 30, 2013, approximately 53% of the Company’s fixed maturity portfolio (including the funds held – directly managed account and funds holding fixed maturity securities) was rated AA (or equivalent rating) or better. At September 30, 2013, approximately 74% the Company’s fixed maturity and short-term investments (including funds holding fixed maturity securities and excluding the funds held – directly managed account) was rated A- or better and 10% was rated below investment grade or not rated. The Company believes this high quality concentration reduces its exposure to credit risk on fixed maturity investments to an acceptable level. At September 30, 2013, the Company is not exposed to any significant credit concentration risk on its investments, excluding securities issued by the U.S. government which are rated AA+. In addition, the single largest corporate issuer and the top 10 corporate issuers accounted for less than 3% and less than 19% of the Company’s total corporate fixed maturity securities (excluding the funds held – directly managed account), respectively, at September 30, 2013. Within the segregated investment portfolio underlying the funds held – directly managed account, the single largest corporate issuer and the top 10 corporate issuers accounted for less than 4% and less than 31% of total corporate fixed maturity securities underlying the funds held – directly managed account at September 30, 2013, respectively.

The Company keeps cash and cash equivalents in several banks and ensures that there are no significant concentrations at any point in time, in any one bank.

To a lesser extent, the Company is also exposed to the following credit risks:

•

as a party to foreign exchange forward contracts and other derivative contracts;

•

in its underwriting operations, most notably in the credit/surety line and for alternative risk products;

•

the credit risk of its cedants in the event of their insolvency or their failure to honor the value of the funds held balances due to the Company;

•

the credit risk of Colisée Re in the event of insolvency or Colisée Re’s failure to honor the value of the funds held balances for any other reason;

•

the credit risk of AXA or its affiliates in the event of their insolvency or their failure to honor their obligations under the Acquisition Agreements (see Business—Reserves—Reserve Agreement in Item 1 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012);

•

as it relates to its business written through brokers if any of the Company’s brokers is unable to fulfill their contractual obligations with respect to payments to the Company;

•

as it relates to its reinsurance balances receivable and reinsurance recoverable on paid and unpaid losses; and

•

under its retrocessional reinsurance contracts.

The concentrations of the Company’s counterparty credit risk exposures have not changed materially at September 30, 2013, compared to December 31, 2012. See Counterparty Credit Risk in Item 7A of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional discussion of credit risks.

Equity Price Risk

The Company invests a portion of its capital funds in marketable equity securities (fair market value of $934 million, excluding funds holding fixed income securities of $188 million) at September 30, 2013. These equity investments are exposed to equity price risk, defined as the potential for loss in market value due to a decline in equity prices. The Company believes that the effects of diversification and the relatively small size of its investments in equities relative to total invested assets mitigate its exposure to equity price risk. The Company estimates that its equity investment portfolio has a beta versus the S&P 500 Index of approximately 0.92 on average. Portfolio beta measures the response of a portfolio’s performance relative to a market return, where a beta of 1 would be an equivalent return to the index. Given the estimated beta for the Company’s equity portfolio, a 10% and 20% movement in the S&P 500 Index would result in a change in the fair value of the Company’s equity portfolio, total invested assets and shareholders’ equity at September 30, 2013 as follows (in millions of U.S. dollars):


	20% Decrease		% Change			10% Decrease		% Change			September 30, 2013		10% Increase		% Change			20% Increase		% Change
Equities⁽¹⁾	$	762		(18	)%	$	848		(9	)%	$	934	$	1,020		9	%	$	1,106		18	%
Total invested assets⁽²⁾		17,343		(1	)		17,429		—			17,515		17,601		—			17,687		1
Shareholders’ equity		6,452		(3	)		6,538		(1	)		6,624		6,710		1			6,796		3

(1)

Excludes funds holding fixed income securities of $188 million.

(2)

Includes total investments, cash and cash equivalents, the investment portfolio underlying the funds held – directly managed account and accrued interest.

This change does not take into account any potential mitigating impact from the fixed maturity securities or taxes.

There was no material change in the absolute or percentage impact of an immediate change of 10% in the S&P 500 Index on the Company’s equity portfolio, total invested assets and shareholders’ equity at September 30, 2013 compared to December 31, 2012.

ITEM 4.

CONTROLS AND PROCEDURES

The Company carried out an evaluation, under the supervision and with the participation of Management, including the Chief Executive Officer and Chief Financial Officer, as of September 30, 2013, of the effectiveness of the design and operation of disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2013, the disclosure controls and procedures are effective such that information required to be disclosed by the Company in reports that it files or submits pursuant to the Securities Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and is accumulated and communicated to Management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosures.

There have been no changes in the Company’s internal control over financial reporting identified in connection with such evaluation that occurred during the three months ended September 30, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.
