2. Summary of significant accounting policies

The accompanying unaudited condensed consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Results for the three and six months ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. The unaudited condensed consolidated financial statements include the accounts of Endurance Holdings and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Management is required to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying disclosures. Actual results could differ from those estimates. Among other matters, significant estimates and assumptions are used to record premiums written and ceded, to record the fair value of investments and to record reserves for losses and loss expenses and contingencies. Estimates and assumptions are periodically reviewed and the effects of revisions are recorded in the consolidated financial statements in the period that they are determined to be necessary.

The balance sheet at December 31, 2012 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2012 contained in Endurance Holdings’ Annual Report on Form 10-K for the fiscal year ended December 31, 2012 (the “2012 Form 10-K”).

Certain comparative information has been reclassified to conform to current year presentation.

2. Summary of significant accounting policies, cont’d.

There were no material changes in the Company’s significant accounting and reporting policies subsequent to the 2012Form 10-K.

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2011-11 “Disclosures About Offsetting Assets and Liabilities” (“ASU 2011-11”). ASU 2011-11 requires additional disclosures about financial instruments and derivative instruments relating to netting arrangements.

ASU 2011-11 was effective for interim and annual periods beginning on or after January 1, 2013, with retrospective presentation required. The Company adopted this standard effective January 1, 2013. This standard did not have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued ASU 2013-02 “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). ASU 2013-02 requires entities to report, in one location, information about reclassifications out of accumulated other comprehensive income (“AOCI”). ASU 2013-02 also requires companies to report changes in AOCI balances. For significant items reclassified out of AOCI into net income in their entirety in the same reporting period, reporting (either on the face of the statement where net income is presented or in the notes to the financial statements) is required about the effect of the reclassifications on the respective line items in the statement where net income is presented. For items that are not reclassified into net income in their entirety in the same reporting period, a cross reference to other disclosures currently required under US GAAP is required in the notes. The above information must be presented in one place (parenthetically on the face of the financial statements by income statement line item or in a note to the financial statements).

ASU 2013-02 was effective for fiscal years and interim periods beginning after December 15, 2012. The Company adopted this standard prospectively on January 1, 2013. This standard resulted in an additional note to the consolidated financial statements (see Note 6).

In July 2013, the FASB issued ASU 2013-11 “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”). The objective of ASU 2013-11 is to improve the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 seeks to reduce the diversity in practice by providing guidance on the presentation of unrecognized tax benefits to better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist.

ASU 2013-11 will be effective for annual and interim reporting periods beginning after December 15, 2013, with both early adoption and retrospective application permitted. The Company is currently evaluating the impact of this guidance; however, the Company does not expect this standard to have a material impact on the Company’s consolidated financial statements.

In addition to the Company’s fixed maturity, short-term and equity investments, the Company invests in (i) hedge funds and private investment funds that generally invest in senior secured bank debt, high yield credit, distressed debt, distressed real estate, derivatives, equity long/short strategies, currencies and commodities (“alternative funds”) and (ii) high yield loan and convertible debt funds (“specialty funds”). The Company’s alternative funds and specialty funds are recorded on the Company’s balance sheet as “other investments”. At June 30, 2013 and December 31, 2012, the Company had invested, net of capital returned, a total of $426.7 million and $394.5 million, respectively, in other investments. At June 30, 2013 and December 31, 2012, the carrying value of other investments was $569.4 million and $517.5 million, respectively. The following table summarizes the composition and redemption restrictions of other investments as of June 30, 2013 and December 31, 2012:

Hedge funds – The redemption frequency of the hedge funds range from monthly to biennially with notice periods from 30 to 90 days. Over one year, it is estimated that the Company can liquidate approximately 78% of the hedge fund portfolio, with the remainder over the following two years.

Private investment funds – The Company generally has no right to redeem its interest in any private investment funds in advance of dissolution of the applicable partnership. Instead, the nature of these investments is that distributions are received by the Company in connection with the liquidation of the underlying assets of the applicable limited partnership. It is estimated that the majority of the underlying assets of the limited partnerships would liquidate over 5 to 10 years from inception of the limited partnership. A secondary market, with unpredictable liquidity, exists for limited partner interests in private equity funds.

High yield loan funds – There are generally no restrictions on the Company’s right to redeem its interest in high yield loan funds with the exception of certain redemption frequency and notice requirements. The redemption frequency of these funds ranges from monthly to quarterly with notice periods from 30 to 90 days.

Convertible debt funds – There are generally no restrictions on the Company’s right to redeem its interest in convertible debt funds with the exception of certain redemption frequency and notice requirements. The redemption frequency of these funds is monthly with a required notice period of 5 days.

(1) Gross unrealized losses include unrealized losses on non-OTTI and non-credit OTTI securities recognized in accumulated other comprehensive income at June 30, 2013.

As of June 30, 2013, 865 available for sale securities were in an unrealized loss position aggregating $65.7 million. Of those, 38 securities with aggregated unrealized losses of $0.7 million at June 30, 2013 had been in a continuous unrealized loss position for twelve months or greater.

The unrealized losses on the Company’s available for sale securities at June 30, 2013 were primarily due to an increase in interest rates and widening of credit spreads, rather than any actual credit losses on these securities. Because the Company has the ability and intent to hold these securities until recovery, the Company currently believes it is probable that it will collect all amounts due according to their respective contractual terms. Therefore, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2013.

Of the $0.6 million (2012: $0.4 million) of OTTI losses recognized by the Company in the second quarter of 2013, the majority was related to expected losses on corporate securities following the Company’s decision to liquidate a specific portfolio. At June 30, 2013, the Company did not have the intent to sell any of the remaining securities in an unrealized loss position and determined that it was unlikely that the Company would be required to sell securities in an unrealized loss position.

The following table provides a roll-forward of the amount related to credit losses for the Company’s available for sale investments recognized in earnings for which a portion of an OTTI loss was recognized in accumulated other comprehensive income for the three and six months ended June 30, 2013:

Variable Interest Entities

Entities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equity investors, as a group, do not have the characteristics of a controlling financial interest are referred to as variable interest entities (“VIE”). A VIE is consolidated by the variable interest holder that is determined to have the controlling financial interest (primary beneficiary) as a result of having both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE’s capital structure, contractual terms, nature of the VIE’s operations and purpose and the Company’s relative exposure to the related risks of the VIE on the date it becomes initially involved in the VIE. The Company reassesses its VIE determination with respect to an entity on an ongoing basis.

The Company is involved in the normal course of business with VIEs primarily as a passive investor in residential and commercial mortgage-backed securities and through its interests in other investments in alternative and specialty funds that are structured as limited partnerships considered to be third party VIEs. The Company determined that it was not the primary beneficiary for any of these investments as of June 30, 2013. The Company believes its exposure to loss with respect to these investments is generally limited to the investment carrying amounts reported in the Company’s Condensed Consolidated Balance Sheets and any unfunded investment commitments.

4. Fair value measurement

The Company determines the fair value of the fixed maturity investments, short-term investments, equity securities, other investments, debt, and other assets and liabilities in accordance with current accounting guidance, which defines fair value and establishes a fair value hierarchy based on inputs to the various valuation techniques used for each fair value measurement. The Company determines the estimated fair value of each individual security utilizing the highest level inputs available. Valuation inputs by security type may include the following:

• Government and agencies fixed maturity securities – These securities are generally priced by pricing services or index providers. The pricing services or index providers may use current market trades for securities with similar quality, maturity and coupon. If no such trades are available, the pricing service typically uses analytical models which may incorporate option adjusted spreads, daily interest rate data and market/sector news. The Company generally classifies the fair values of government and agencies securities in Level 2. Current issue U.S. government securities are generally valued based on Level 1 inputs, which use the market approach valuation technique.

• Government guaranteed corporate fixed maturity securities – These securities are generally priced by pricing services or index providers. The pricing service or index providers may use current market trades for securities with similar quality, maturity and coupon. If no such trades are available, the pricing service typically uses analytical spread models which may incorporate inputs from the U.S treasury curve or LIBOR. The Company generally classifies the fair values of its government guaranteed corporate securities in Level 2.

• Corporate fixed maturity securities – These securities are generally priced by pricing services or index providers. The pricing services or index providers typically use discounted cash flow models that incorporate benchmark curves for treasury, swap and high issuance credits. Credit spreads are developed from current market observations for like or similar securities. The Company generally classifies the fair values of its corporate securities in Level 2.

• Equity securities – These securities are generally priced by pricing services or index providers. Depending on the type of underlying equity security or equity fund, the securities are priced by pricing services or index providers based on quoted market prices in active markets or through a discounted cash flow model that incorporates benchmark curves for treasury, swap and credits for like or similar securities. The Company generally classifies the fair values of its equity securities in Level 1 or 2.

4. Fair value measurement, cont’d.

• Other assets and liabilities – These balances include a variety of derivative instruments used to enhance the efficiency of the investment portfolio and economically hedge certain risks. These instruments are generally priced by pricing services, broker/dealers and/or recent trading activity. The market value approach valuation technique is used to estimate the fair value for these derivatives based on significant observable market inputs. Certain derivative instruments are priced by pricing services based on quoted market prices in active markets. These derivative instruments are generally classified in Level 1. Other derivative instruments are priced using industry valuation models and are considered Level 2, as the inputs to the valuation model are based on observable market inputs. Also included in this line item are proprietary, non-exchange traded derivative-based risk management products primarily used to address weather and energy risks. The trading market for these weather derivatives is generally linked to energy and agriculture commodities, weather and other natural phenomena. In instances where market prices are not available, the Company uses industry or internally developed valuation techniques such as spread option, Black Scholes, quanto and simulation modeling to determine fair value and classifies these in Level 3. These models may reference prices for similar instruments.

• Structured securities including agency and non-agency, residential and commercial, mortgage and asset-backed securities – These securities are generally priced by broker/dealers. Broker/dealers may use current market trades for securities with similar qualities. If no such trades are available, inputs such as bid and offer, prepayment speeds, the U.S. treasury curve, swap curve and cash settlement may be used in a discounted cash flow model to determine the fair value of a security. The Company generally classifies the fair values of its structured securities in Level 2.

• Other investments – Other investments, including alternative funds and specialty funds, are generally priced on net asset values (“NAV”) received from the fund managers or administrators. Due to the timing of the delivery of the final NAV by certain of the fund managers, valuations of certain alternative funds and specialty funds are estimated based on the most recently available information, including period end NAVs, period end estimates, or, in some cases, prior month or prior quarter NAVs. As this valuation technique incorporates both observable and significant unobservable inputs, the Company generally classifies the fair value of its other investments in Level 3.

• Debt – Outstanding debt consists of the Company’s 6.15% Senior Notes due October 15, 2015 and the 7.0% Senior Notes due July 15, 2034 (the “Senior Notes”). The fair values of these securities were obtained from a third party pricing service and pricing was based on the spread above the risk-free yield curve. These spreads are generally obtained from the new issue market, secondary trading and broker-dealer quotes. As these spreads and the yields for the risk-free yield curve are observable market inputs, the fair values of the Senior Notes are classified in Level 2.

The carrying values of cash and cash equivalents, accrued investment income, net receivable on sales of investments, net payable on purchases of investments and other financial instruments not described above approximated their fair values at June 30, 2013.

Transfers between levels are assumed to occur at the end of each period.

5. Earnings per share

The two-class method utilized by the Company is an earnings allocation formula that determines earnings per share for the holders of Endurance Holdings’ ordinary shares (also referred to as “common shares”) and participating common shares, which includes unvested restricted shares that receive cash dividends, according to dividends declared and participation rights in undistributed earnings. Net income available to common and participating common shareholders is reduced by the amount of dividends declared in the current period and by the contractual amount of dividends that must be paid for the current period related to the Company’s common and participating common shares. Any remaining undistributed earnings are allocated to the common and participating common shareholders to the extent that each security may share in earnings as if all of the earnings for the period had been distributed. In periods of loss, no losses are allocated to participating common shareholders. Instead, all such losses are allocated solely to the common shareholders.

Basic earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding. The weighted average number of common shares excludes any dilutive effect of outstanding options and convertible securities such as unvested restricted shares.

Diluted earnings per common share are based on the weighted average number of common shares and assumes the exercise of all dilutive stock options and the vesting or conversion of all convertible securities such as unvested restricted shares using the two-class method described above.

The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended June 30, 2013 and 2012:

7. Derivatives

The Company’s derivative instruments are recorded in the Condensed Consolidated Balance Sheets at fair value, with changes in fair value and gains and losses recognized in net realized and unrealized investment gains, net foreign exchange losses (gains) and other underwriting income (loss) in the Condensed Consolidated Statements of Income and Comprehensive (Loss) Income.

During 2012, the Company entered into the weather risk management business through its newly formed unit, Endurance Global Weather. Endurance Global Weather regularly transacts in certain derivative-based risk management products primarily to address weather and energy risks. The trading markets for these derivatives are generally linked to energy and agriculture commodities, weather and other natural phenomena. Generally, the Company’s current portfolio of such derivative contracts is of short duration and such contracts are predominantly seasonal in nature.

The Company’s derivatives are not designated as hedges under current accounting guidance. The Company invests a portion of its fixed maturity assets with third party investment managers with investment guidelines that permit the use of derivative instruments. The Company may enter derivative transactions directly or as part of strategies employed by its external investment managers. The Company’s objectives for holding these derivatives are as follows:

Interest Rate Futures, Swaps, Swaptions and Options- to manage exposure to interest rate risk, which can include increasing or decreasing its exposure to this risk through modification of the portfolio composition and duration.

Foreign Exchange Forwards, Futures and Options- as part of overall currency risk management and investment strategies.

Credit Default Swaps - to manage market exposures. The Company may assume or economically hedge credit risk through credit default swaps to replicate or hedge investment positions. The original term of these credit default swaps is generally five years or less.

Commodity Futures and Options- to economically hedge certain underwriting risks.

To-Be-Announced Mortgage-backed Securities (“TBAs”)- to enhance investment performance and as part of overall investment strategy. TBAs represent commitments to purchase or sell a future issuance of agency mortgage-backed securities. For the period between purchase of a TBA and issuance of the underlying securities, the Company’s position is accounted for as a derivative.

Energy and Weather Contracts- to address weather and energy risks. The Company may purchase or sell contracts with financial settlements based on the performance of an index linked to a quantifiable weather element, such as temperature, precipitation, snowfall or wind speed, and structures with multiple risk triggers indexed to a quantifiable weather element and a weather sensitive commodity price, such as temperature and electrical power or natural gas.

On January 1, 2013, the Company adopted new guidance that requires disclosure of financial instruments subject to a master netting agreement. At June 30, 2013, derivative assets of $0.7 million and liabilities of $1.5 million were traded under International Swaps and Derivatives Association Master Agreements (“ISDAs”) which provide for the ability to settle the derivative asset and liability with each counterparty on a net basis. TBAs and interest rate futures are not subject to ISDAs. At June 30, 2013 and December 31, 2012, none of the Company’s derivative instruments were netted. See Note 10 for information on collateral pledged.

9. Segment reporting, cont’d.

Reinsurance segment lines of business

• Catastrophe

• Property

• Casualty

• Other specialty

Management measures segment results on the basis of the combined ratio, which is obtained by dividing the sum of the net losses and loss expenses, acquisition expenses and general and administrative expenses by net premiums earned. When purchased within a single line of business, ceded reinsurance and recoveries are accounted for within that line of business. When purchased across multiple lines of business, ceded reinsurance and recoveries are allocated to the lines of business in proportion to the related risks assumed. The Company does not manage its assets by segment; accordingly, investment income and total assets are not allocated to the individual business segments. General and administrative expenses incurred by the segments are allocated directly. Remaining general and administrative expenses not directly incurred by the segments are allocated primarily based on estimated consumption, headcount and other variables deemed relevant to the allocation of such expenses. Ceded reinsurance and recoveries are recorded within the business segment to which they apply.

The following table provides a summary of segment revenues, results and reserves for losses and loss expenses for the three months ended June 30, 2013:

Overview

Endurance Holdings was organized as a Bermuda holding company on June 27, 2002 and has seven wholly-owned operating subsidiaries:

• Endurance Specialty Insurance Ltd. (“Endurance Bermuda”), domiciled in Bermuda with branch offices in Switzerland and Singapore;

• Endurance Reinsurance Corporation of America (“Endurance U.S. Reinsurance”), domiciled in Delaware;

• Endurance Worldwide Insurance Limited (“Endurance U.K.”), domiciled in England;

• Endurance American Insurance Company (“Endurance American”), domiciled in Delaware;

• Endurance American Specialty Insurance Company (“Endurance American Specialty”), domiciled in Delaware;

• Endurance Risk Solutions Assurance Co. (“Endurance Risk Solutions”), domiciled in Delaware; and

• American Agri-Business Insurance Company (“American Agri-Business”), domiciled in Texas and managed by ARMtech Insurance Services, Inc. (together with American Agri-Business, “ARMtech”).

The Company writes specialty lines of property and casualty insurance and reinsurance on a global basis and seeks to create a portfolio of specialty lines of business that are profitable and have limited correlation with one another. The Company’s portfolio of specialty lines of business is organized into two business segments, Insurance and Reinsurance.

In the Insurance segment, the Company writes agriculture, casualty and other specialty, professional lines, and property insurance. In the Reinsurance segment, the Company writes catastrophe, property, casualty, and other specialty reinsurance.

37

The Company’s Insurance and Reinsurance segments both include property related coverages which provide insurance or reinsurance of an insurable interest in tangible property for property loss, damage or loss of use. In addition, the Company’s Insurance and Reinsurance segments include various casualty insurance and reinsurance coverages which are primarily concerned with the losses caused by injuries to third parties, i.e., not the insured, or to property owned by third parties and the legal liability imposed on the insured resulting from such injuries.

Application of Critical Accounting Estimates

The Company’s condensed consolidated financial statements are based on the selection of accounting policies and application of significant accounting estimates which require management to make significant estimates and assumptions. The Company believes that some of the more critical judgments in the areas of accounting estimates and assumptions that affect its financial condition and results of operations are related to the recognition of premiums written and ceded, reserves for losses and loss expenses, other-than-temporary impairments within the investment portfolio and fair value measurements of certain portions of the investment portfolio. For a detailed discussion of the Company’s critical accounting estimates, please refer to the 2012 Form 10-K and the Notes to the Unaudited Condensed Consolidated Financial Statements in this Form 10-Q. There were no material changes in the application of the Company’s critical accounting estimates subsequent to the 2012 Form 10-K. Management has discussed the application of these critical accounting estimates with the Company’s Board of Directors and the Audit Committee of the Board of Directors.

Premiums

Gross premiums written in the three months ended June 30, 2013 were $572.7 million, a decrease of $31.4 million, or 5.2%, compared to the same period in 2012. Net premiums written in the three months ended June 30, 2013 were $464.6 million, a decrease of $19.8 million, or 4.1%. The change in net premiums written was driven by the following factors:

• A decrease in the catastrophe line of the Reinsurance segment, reflecting the impact of a more competitive market where pricing declined and reduced limits on certain renewal contracts, particularly on Florida exposures;

• A decline in premiums in the property line of the Reinsurance segment as the Company non-renewed business where price weakening led to profitability being below target levels;

• An increase in the casualty line of the Reinsurance segment driven primarily by two new contracts written in its U.S. based operations;

• An increase in net premiums in the agriculture line of the Insurance segment in the second quarter, primarily due to the net premiums in the comparable period in 2012 being impacted by ceded premium adjustments that did not recur this year; and

• A decrease in professional lines premiums in the Insurance segment, due primarily to the non-renewal of a large program relationship in late 2012.

The decrease in ceded premiums written by the Company in the quarter ended June 30, 2013 as compared to the same period in 2012 was primarily driven by the agriculture line of the Insurance segment as the Company ceded more premiums to the U.S. government in the second quarter of 2012, offset partially by the Company choosing to purchase additional protection in the current period in the catastrophe and property lines of the Reinsurance segment.

Net premiums earned for the three months ended June 30, 2013 were $543.3 million, an increase of $24.0 million, or 4.6%, from the second quarter of 2012. The increase in net premiums earned resulted from the growth in net premiums written, primarily in the property reinsurance line of business over the last twelve months.

Net Investment Income

The Company’s net investment income of $32.5 million increased by 2.2% or $0.7 million for the quarter ended June 30, 2013 as compared to the same period in 2012. Net investment income during the second quarter of 2013 included net mark to market gains of $6.8 million on other investments, comprised of alternative funds and specialty funds, as compared to mark to market losses of $0.1 million in the second quarter of 2012. Investment income generated from the Company’s available for sale investments, which consist of fixed maturity investments, short-term investments and equity securities, declined by $6.0 million for the three months ended June 30, 2013 compared to the same period in 2012. This decline resulted primarily from lower reinvestment rates over the past 12 months. Investment expenses, including investment management fees, for the three months ended June 30, 2013 were $3.8 million compared to $3.2 million for the same period in 2012.

39

The annualized net earned yield and total return of the investment portfolio for the three months ended June 30, 2013 and 2012 and the market yield and portfolio duration as of June 30, 2013 and 2012 were as follows:

	Three Months Ended June 30,
	2013			2012
Annualized net earned yield(1)		2.04	%		2.06	%
Total return on investment portfolio(2)		(1.22	)%		0.90	%
Market yield(3)		2.00	%		1.63	%
Portfolio duration(4)		3.05 years			2.60 years

(1) The actual net earned income from the investment portfolio after adjusting for expenses and accretion of discount and amortization of premium from the purchase price divided by the average book value of assets.

(2) Net of investment manager fees; includes realized and unrealized gains and losses.

(3) The internal rate of return of the investment portfolio based on the given market price or the single discount rate that equates a security price (inclusive of accrued interest) for the portfolio with its projected cash flows. Excludes other investments and operating cash.

(4) Includes only cash and cash equivalents and fixed income investments managed by the Company’s

investment managers.

During the second quarter of 2013, the yield on the benchmark three year U.S. Treasury bond fluctuated within a 46 basis point range, with a high of 0.75% and a low of 0.29%. Trading activity in the Company’s portfolio during the second quarter included reductions in corporates, U.S. government residential mortgage-backed securities, and U.S. government and government agencies securities, and increased allocations to foreign government bonds, commercial mortgage-backed securities, and equity securities. The duration of the fixed income investments increased to 3.05 years at June 30, 2013 from 2.49 years at December 31, 2012, primarily due to the increase in interest rates which reduced the rate of prepayments underlying the Company’s mortgage-backed securities portfolio, causing their average maturity to extend.

Net Realized and Unrealized Investment Gains

The Company’s investment portfolio is actively managed on a fair value basis to generate attractive economic returns and income. Movements in financial markets and interest rates influence the timing and recognition of net realized investment gains and losses as the portfolio is adjusted and rebalanced. Proceeds from sales of investments classified as available for sale during the three months ended June 30, 2013 were $937.4 million compared to $719.6 million during the same period a year ago. Net realized investment gains decreased during the three months ended June 30, 2013 compared to the same period in 2012. Realized investment gains and losses and the change in the fair value of derivative financial instruments for the three months ended June 30, 2013 and 2012 were as follows:

	Three Months Ended June 30,
	2013			2012
	(U.S. dollars in thousands)
Gross realized gains on investment sales	$	16,591		$	15,613
Gross realized losses on investment sales		(5,283	)		(822	)
Change in fair value of derivative financial instruments		(936	)		167
Net realized and unrealized investment gains	$	10,372		$	14,958

Net impairment losses recognized in earnings for the three months ended June 30, 2013 and 2012 were $0.6 million and $0.4 million, respectively.

40

Net Foreign Exchange Gains and Losses

For the three months ended June 30, 2013, the Company remeasured its monetary assets and liabilities denominated in foreign currencies, which resulted in a net foreign exchange loss of $3.4 million compared to a net foreign exchange gain of $0.3 million for the same period of 2012. The current period net foreign exchange loss resulted from offsetting exposures across the Company as the U.S. dollar strengthened against the Japanese Yen, Australian dollar and New Zealand dollar in the period. In the prior year, the minimal gain resulted from the offsetting impact of the U.S. dollar weakening against the Japanese Yen and strengthening against other major currencies, together with Company’s strategy of pursuing a balanced asset liability position by major currency.

Net Losses and Loss Expenses

The Company’s net losses and loss expense ratio for the three months ended June 30, 2013 decreased compared to the same period in 2012 due to increased levels of favorable prior year loss reserve development partially offset by increased levels of catastrophe related activity.

Favorable prior year loss reserve development was $62.8 million for the second quarter of 2013 compared to $19.6 million during the same period in 2012. In the second quarter of 2013, prior year loss reserves emerged favorably across all lines business of the Insurance and Reinsurance segments. Favorable reserve development in the second quarter of 2013 was higher than the second quarter of 2012 principally in the Reinsurance segment due to lower than expected reported losses in the property and catastrophe lines and from reductions in reserve estimates related to the Thailand flood losses of 2011 and Superstorm Sandy losses in 2012. Comparatively, the second quarter of 2012 experienced adverse development on some of the major 2011 loss events.

The following table details the impact of the catastrophe related activity for the three months ended June 30, 2013 and 2012.

Three Months Ended June 30, 2013			Three Months Ended June 30, 2012
Event	Net Loss		Event	Net Loss
(U.S. dollars in millions)
Floods in Canada	$	11.3	Earthquake in Italy	$	6.2
Floods in Europe		23.7	Windstorms in the United States		8.2
Windstorms in the United States		12.4
	$	47.4		$	14.4

For the three months ended June 30, 2013, natural catastrophe related losses added 9.3 percentage points to the Company’s net loss ratio after adjustment for reinstatement premiums and other loss sensitive accruals compared to 2.8 percentage points in the same period in 2012. In addition, the Company recorded a higher expected loss ratio in the second quarter of 2013 in the agriculture line of the Insurance segment reflecting a more challenging winter wheat growing season and a higher level of prevented planting claims for spring crops, which was offset by lower recorded reserves for attritional losses in the Insurance segment’s property, professional and casualty and other lines in the three months ended June 30, 2013 compared to the same period in 2012.

The Company participates in lines of business where claims may not be reported for many years. Accordingly, management does not believe that reported claims are the only valid means for estimating ultimate obligations. Ultimate losses and loss expenses may differ materially from the amounts recorded in the Company’s consolidated financial statements. These estimates are reviewed regularly and, as experience develops and new information becomes known, the reserves are adjusted as necessary. Reserve adjustments, if any, are recorded in earnings in the period in which they are determined. The overall loss reserves were established by the Company’s actuaries and reflect management’s best estimate of ultimate losses. See “Reserve for Losses and Loss Expenses” below for further discussion.

41

Acquisition Expenses

The acquisition expense ratio for the three months ended June 30, 2013 was modestly lower compared with the same period in 2012 due to a higher proportion of net earned premiums attributed to the agriculture line in the Insurance segment, which incurs a lower net acquisition expense rate, and due to the property reinsurance business line that has grown over the last twelve months, exhibiting a lower average acquisition expense rate than in prior periods.

General and Administrative Expenses

The Company’s general and administrative expense ratio for the second quarter of 2013 increased by 2.9 percentage points compared to the same period in 2012 due to an increase in personnel costs related to the addition of new underwriting teams over the last twelve months, current period costs associated with the Company’s senior leadership transition and increased annual incentive costs associated with improved year to date corporate operating results in 2013. At June 30, 2013, the Company had a total of 927 employees compared to 849 employees at June 30, 2012.

Income Tax Benefit (Expenses)

The Company recorded a tax benefit for the quarter ended June 30, 2013 of $0.9 million compared to a tax expense of $1.1 million for the quarter ended June 30, 2012. The current period tax benefit resulted from net losses recorded at the Company’s United States taxable jurisdictions, partially offset by increases recorded on the Company’s deferred tax asset valuation allowance.

Net Income

The Company generated net income of $61.0 million in the three months ended June 30, 2013 compared to net income of $72.5 million in the same period of 2012 primarily as a result of an increase in catastrophe losses and personnel costs partially offset by growth in net premiums earned and increased favorable prior year reserve development during the current period.

Premiums

Gross premiums written in the six months ended June 30, 2013 were $1,750.1 million, an increase of $84.3 million, or 5.1%, compared to the same period in 2012. Net premiums written in the six months ended June 30, 2013 were $1,373.5 million, an increase of $46.1 million, or 3.5%, compared to the same period in 2012. The change in net premiums written was driven by the following factors:

• Growth in premiums in the Reinsurance segment, principally due to new property premiums and modest rate increases on renewed business, particularly from the Company’s London, Zurich and Singapore offices;

• An expansion of net written premiums in the other specialty line of the Reinsurance segment, primarily due to new business generated by the trade credit and surety team that joined the Company in late 2012, partially offset by an absence of positive premium adjustments compared to 2012 and clients increasing their retentions upon renewal of certain treaties;

• An increase of premiums in the casualty line of the Reinsurance segment as a result of new business written on international motor and U.S. casualty treaties;

43

• A decrease of premiums in the catastrophe line of the Reinsurance segment reflecting the impact of a more competitive market where pricing declined and the Company chose to selectively reduce limits on some U.S. business, particularly in Florida; and

• A decrease in premiums in the Insurance segment, primarily in professional lines driven by the non-renewal of a large program relationship in late 2012.

Net premiums earned for the six months ended June 30, 2013 were $963.5 million, an increase of $32.5 million, or 3.5%, from the six months ended June 30, 2012 principally due to growth in net premiums written experienced over the last twelve months compared to the same period last year.

Net Investment Income

The Company’s net investment income of $81.8 million decreased by 8.0% or $7.1 million for the six months ended June 30, 2013 as compared to the same period in 2012. Net investment income during the first six months of 2013 included net mark to market gains of $29.8 million on other investments, comprised of alternative funds and specialty funds, as compared to mark to market gains of $23.1 million in the first six months of 2012. Investment income generated from the Company’s available for sale investments, which consist of fixed maturity investments, short-term investments and equity securities, declined by $13.5 million for the six months ended June 30, 2013 compared to the same period in 2012. This decline resulted primarily from lower reinvestment rates over the past 12 months, partly offset by a higher average investment portfolio balance. Investment expenses, including investment management fees, for the six months ended June 30, 2013 were $7.5 million compared to $6.6 million for the same period in 2012.

The annualized net earned yield and total return on the investment portfolio for the six months ended June 30, 2013 and 2012 and the market yield and portfolio duration as of June 30, 2013 and 2012 were as follows:

	Six Months Ended June 30,
	2013			2012
Annualized net earned yield(1)		2.56	%		2.89	%
Total return on investment portfolio(2)		(0.62	)%		2.29	%
Market yield(3)		2.00	%		1.63	%

During the six months ended June 30, 2013, the yield on the benchmark three year U.S. Treasury bond fluctuated within a 45 basis point range, with a high of 0.75% and a low of 0.29%. Trading activity in the Company’s portfolio for the six months ended June 30, 2013 included reductions in corporate securities, U.S. government residential mortgage-backed securities, and U.S. government and government agencies securities and increased allocations to foreign government bonds, non-agency commercial mortgage-backed securities, asset-backed securities, equity securities and other investments. The duration of the fixed income investments increased to 3.05 years at June 30, 2013 from 2.49 years at December 31, 2012, primarily due to the increase in interest rates which reduced the rate of prepayments underlying the Company’s mortgage-backed securities portfolio causing their average maturity to extend.

Net Realized and Unrealized Investment Gains

The Company’s investment portfolio is actively managed on a fair value basis to generate attractive economic returns and income. Movements in financial markets and interest rates influence the timing and recognition of net realized investment gains and losses as the portfolio is adjusted and rebalanced. Proceeds from sales of investments classified as available for sale during the six months ended June 30, 2013 were $1,395.5 million compared to $1,552.9 million during the same period a year ago. Net realized investment gains decreased during the six months ended June 30, 2013 compared to the same period in 2012.

Realized investment gains and losses and the change in the fair value of derivative financial instruments for the six months ended June 30, 2013 and 2012 were as follows:

	Six Months Ended June 30,
	2013			2012
	(U.S. dollars in thousands)
Gross realized gains on investment sales	$	24,011		$	22,861
Gross realized losses on investment sales		(6,746	)		(3,169	)
Change in fair value of derivative financial instruments		(658	)		469
Net realized and unrealized investment gains	$	16,607		$	20,161

Net impairment losses recognized in earnings for the six months ended June 30, 2013 and 2012 were $1.4 million and $0.6 million, respectively.

Net Foreign Exchange Gains

For the six months ended June 30, 2013, the Company remeasured its monetary assets and liabilities denominated in foreign currencies, which resulted in a net foreign exchange loss of $6.3 million compared to a gain of $18.5 million for the same period in 2012. The current period net foreign exchange loss resulted from offsetting exposures across the Company as the U.S. dollar strengthened against the Japanese Yen, Australian dollar and New Zealand dollar in the period. In the prior year the gain resulted from a decrease in the value of Japanese Yen net liabilities as the U.S. dollar strengthened against the Yen in the first half of the year.

Net Losses and Loss Expenses

The Company’s net losses and loss expense ratio for the six months ended June 30, 2013 decreased compared to the same period in 2012 due to increased levels of favorable prior year loss reserve development partially offset by increased levels of catastrophe related activity.

Favorable prior year loss reserve development was $113.5 million for the six months ended June 30, 2013 as compared to $36.5 million for the same period in 2012. In the six months ended June 30, 2013, prior year loss reserves emerged favorably across all lines of the Insurance segment and Reinsurance segment. In the six months ended June 30, 2012, prior year loss reserves emerged favorably across all lines of the Insurance segment and across the catastrophe, casualty and other specialty lines of the Reinsurance segment. Favorable reserve development in the first six months of 2013 was significantly higher than the first six months of 2012 principally in the Reinsurance segment due to much lower than expected reported losses in the property and catastrophe lines and from reductions in reserve estimates related to the Thailand flood losses of 2011 and Superstorm Sandy losses in 2012. Comparatively, the first half of 2012 included notable adverse development on some of the major 2011 loss events impacting the property line of business.

The following table details the impact of the catastrophe related activity for the six months ended June 30, 2013 and 2012.

Six Months Ended June 30, 2013			Six Months Ended June 30, 2012
Event	Net Loss		Event	Net Loss
(U.S. dollars in millions)
Floods in Canada		11.3	Windstorms in Kentucky		22.5
Floods in Europe		23.7	Earthquake in Italy		6.2
Windstorms in the United States		12.4	Windstorms in the United States		8.2
	$	47.4		$	36.9

For the six months ended June 30, 2013, catastrophe related losses added 5.2 percentage points to the Company’s net loss ratio after adjustment for reinstatement premiums and other loss sensitive accruals compared to 4.2 percentage points in the same period in 2012. In addition, the Company recorded a higher expected loss ratio in the agriculture line of the Insurance segment reflecting a more challenging winter wheat growing season and a higher level of prevented planting claims for spring crops. The overall increase in current year net losses incurred was partially offset by lower levels of attritional losses in the Insurance segment’s property and casualty and other lines in the six months ended June 30, 2013 compared to the same period in 2012.

The Company participates in lines of business in which claims may not be reported for many years. Accordingly, management does not believe that reported claims are the only valid means for estimating ultimate obligations. Ultimate losses and loss expenses may differ materially from the amounts recorded in the Company’s consolidated financial statements. These estimates are reviewed regularly and, as experience develops and new information becomes known, the reserves are adjusted as necessary. Reserve adjustments, if any, are recorded in earnings in the period in which they are determined. The overall loss reserves were established by the Company’s actuaries and reflect management’s best estimate of ultimate losses. See “Reserve for Losses and Loss Expenses” below for further discussion.

Acquisition Expenses

The acquisition expense ratio for the six months ended June 30, 2013 was comparable to the same period in 2012.

General and Administrative Expenses

The Company’s general and administrative expense ratio for the six months ended June 30, 2013 was higher than the same period in 2012 due to an increase in personnel costs related to the addition of new underwriting teams over the last twelve months, current period costs associated with the Company’s CEO transition and increased annual incentive costs associated with improved year to date corporate operating results in 2013. The comparable period in 2012 also benefited from a lower 2012 payout of the Company’s 2011 annual incentive compensation than was previously accrued.

Income Tax Expense

The Company recorded a tax expense for the six months ended June 30, 2013 of $3.3 million compared to a tax expense of $0.9 million for the same period in 2012 due to adjustments to deferred tax valuation allowances at the Company’s U.S. taxable jurisdictions in 2013.

Net Income

The Company produced net income of $161.3 million for the six months ended June 30, 2013 compared to a net income of $155.0 million in the same period of 2012 primarily due to increased net premiums earned and favorable prior year loss development, partially offset by higher general and administrative expenses and foreign exchange losses.

Reserve for Losses and Loss Expenses

As of June 30, 2013, the Company had accrued losses and loss expense reserves of $4.1 billion (December 31, 2012 - $4.2 billion). This amount represents management’s best estimate of the ultimate liability for payment of losses and loss expenses related to loss events. During the six months ended June 30, 2013 and 2012, the Company’s net paid losses and loss expenses were $549.3 million and $389.9 million, respectively.

As more fully described under “Reserving Process” in the Company’s Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2012 Form 10-K, the Company incorporates a variety of actuarial methods and judgments in its reserving process. Two key inputs in the various actuarial methods employed by the Company are initial expected loss ratios and expected loss reporting patterns. These key inputs impact the potential variability in the estimate of the reserve for losses and loss expenses and are applicable to each of the Company’s business segments. The Company’s loss and loss expense reserves consider and reflect, in part, deviations resulting from differences between expected loss and actual loss reporting as well as judgments relating to the weights applied to the reserve levels indicated by the actuarial methods. Expected loss reporting patterns are based upon internal and external historical data and assumptions regarding claims reporting trends over a period of time that extends beyond the Company’s own operating history.

Differences between actual reported losses and expected losses are anticipated to occur in any individual period and such deviations may influence future initial expected loss ratios and/or expected loss reporting patterns as the recent actual experience becomes part of the historical data utilized as part of the ongoing reserve estimation process. The Company has demonstrated the impact of changes in the speed of the loss reporting patterns, as well as changes in the expected loss ratios, within the table under the heading “Potential Variability in Reserves for Losses and Loss Expenses” in the Company’s Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2012 Form 10-K.

Losses and loss expenses for the three and six months ended June 30, 2013 included $62.8 million and $113.5 million in favorable development of reserves relating to prior accident years, respectively. The favorable loss reserve development experienced during the three and six months ended June 30, 2013 benefited the Company’s reported loss ratio by approximately 11.6 and 11.8 percentage points, respectively. This net reduction in estimated losses for prior accident years reflects lower than expected claims emergence for the six months ended June 30, 2013 in all lines of business within the Insurance and Reinsurance segments.

For the three and six months ended June 30, 2013, the Company did not materially alter any key inputs utilized to establish reserve for losses and loss expenses (initial expected loss ratios and loss reporting patterns) related to prior years for the insurance and reinsurance segments as the variances in reported losses for those segments were within the range of possible results anticipated by the Company.

Losses and loss expenses for the three and six months ended June 30, 2012 included $19.6 million and $36.5 million in favorable development of reserves relating to prior accident years, respectively. The favorable loss reserve development experienced during the three and six months ended June 30, 2012 benefited the Company’s reported loss ratio by approximately 3.8 and 3.9 percentage points, respectively. This net reduction in estimated losses for prior accident years resulted primarily from lower than expected claims emergence across all lines of business for both the three and six months ended June 30, 2012 included within the Insurance segment and the catastrophe, casualty and other specialty lines of business in the Reinsurance segment for both the three and six months ended June 30, 2012.

For the three and six months ended June 30, 2012, the Company did not materially alter the two key inputs utilized to establish its reserve for losses and loss expenses (initial expected loss ratios and loss reporting patterns) for business related to prior years for the insurance and reinsurance segments as the variances in reported losses for those segments were within the range of possible results anticipated by the Company.

49

Insurance

Agriculture.For the three and six months ended June 30, 2013 and 2012, the Company recorded favorable loss emergence due to lower than anticipated agriculture claims settlements for the 2012 and 2011 crop years.

Casualty and other specialty.For the three and six months ended June 30, 2013, the Company recorded favorable loss emergence within this line of business primarily due to lower than expected claims activity within the healthcare liability business. This favorable loss emergence was partially offset by adverse development within the U.S. based casualty business. For the three and six months ended June 30, 2012, the Company recorded favorable loss emergence within this line of business primarily due to favorable loss development within the healthcare liability and casualty businesses, partially offset by adverse development within the workers’ compensation business. The Company exited the workers’ compensation insurance line of business in 2009.

Professional lines. For the three and six months ended June 30, 2013, the Company recorded a modest amount of favorable loss emergence within this line of business, primarily due to lower than expected reported claims activity in the U.S. based director and officers’ liability business. For the three and six months ended June 30, 2012, the Company recorded favorable loss emergence in professional lines due to lower than expected claims activity.

Property. For the three and six months ended June 30, 2013 and 2012, the favorable loss emergence within the property line of business was primarily due to lower than expected reported and favorable case reserve development.

Reinsurance

Catastrophe. For the six months ended June 30, 2013 and 2012, the Company recorded significant favorable loss emergence within this line of business primarily due to lower than expected claims activity and favorable case reserve development, primarily related to the Thailand floods of 2011 and Superstorm Sandy in 2012.

Property. For the three and six months ended June 30, 2013, the Company recorded favorable loss emergence in the property line of business due to lower than expected claims activity and favorable case reserve development, primarily related to the Thailand floods of 2011 and Superstorm Sandy in 2012. For the three and six months ended June 30, 2012, the Company recorded unfavorable loss emergence in the property line of business due to higher than expected claims activity related to 2011 catastrophes.

Casualty. For the three and six months ended June 30, 2013 and 2012, the Company recorded favorable loss emergence within this line of business primarily due to lower than expected claims reported.

Other specialty. For the three and six months ended June 30, 2013 and 2012, the Company recorded favorable loss emergence within this line of business primarily due to lower than expected claims reported.

Underwriting Results by Business Segments

The determination of the Company’s business segments is based on the manner in which management monitors the performance of the Company’s underwriting operations. As a result, we report two business segments – Insurance and Reinsurance.

Management measures the Company’s results on the basis of the combined ratio, which is obtained by dividing the sum of the losses and loss expenses, acquisition expenses and general and administrative expenses by net premiums earned. The Company’s historic combined ratios may not be indicative of future underwriting performance. When purchased within a single line of business, ceded reinsurance and recoveries are accounted for within that line of business. When purchased across multiple lines of business, ceded reinsurance and recoveries are allocated to the lines of business in proportion to the related risks assumed. The Company does not manage its assets by business segment; accordingly, investment income and total assets are not allocated to the individual business segments. General and administrative expenses incurred by the business segments are allocated directly. Remaining general and administrative expenses not directly incurred by the business segments are allocated primarily based on estimated consumption, headcount and other variables deemed relevant to the allocation of such expenses. Ceded reinsurance and recoveries are recorded within the business segment to which they apply.

Insurance

The following table summarizes the underwriting results and associated ratios for the Company’s Insurance segment for the three and six months ended June 30, 2013 and 2012.

The increase in the Insurance segment net premiums written for the three months ended June 30, 2013 and the decrease for the six months ended June 30, 2013 compared to the same periods in 2012 were driven by the following factors:

• An increase in net premiums written within the agriculture line of business, as strong growth in policy counts driven by attracting new business was partially offset by higher cessions to the U.S. Government and third parties;

• A decrease in premiums in professional lines driven by the non-renewal of a large program relationship in late 2012; and

• Growth in premiums in the property line emanating from the Company’s contract binding authority business where new agents have been added, partially offset by business curtailed in several product lines in an effort to reallocate capital to more profitable lines of business.

Net premiums earned by the Company in the Insurance segment decreased in the six months ended June 30, 2013 compared to the same period in 2012 primarily due to the decrease in net premiums written in professional lines. Net premiums earned by the Company in the Insurance segment in the three months ended June 30, 2013 were comparable to the same period in 2012.

Losses and Loss Expenses. The net loss ratio in the Company’s Insurance segment increased by 2.2 percentage points for the three month period ended June 30, 2013 compared to the same period in 2012 and was

53

comparable for the six month periods ended June 30, 2013 and 2012. During the three and six months ended June 30, 2013, the Company’s previously estimated loss and loss expense reserve for the Insurance segment for prior accident years was reduced by $5.6 million and $22.9 million, respectively, which decreased the net loss ratio by 2.1 and 5.5 percentage points, as compared to reductions of $13.6 million and $21.5 million, which decreased the net loss ratio by 5.1 and 5.0 percentage points for the three and six months ended June 30, 2012. The lower level of favorable loss development in the second quarter of 2013 compared to 2012 was driven by the agriculture and casualty and other lines of business which experienced lower than expected claims activity in 2012.

Partially offsetting the decreased level of current period favorable prior year loss reserve releases in the three months ended June 30, 2013 was a decrease in certain current period accident quarter loss ratios compared to the three month period ended June 30, 2012. The current accident quarter loss ratio decreased by 0.8 percentage points for the three months ended June 30, 2013 compared to the same period in 2012 due to lower loss ratios in the Company’s property, professional and casualty and other lines from decreased levels of attritional loss activity in the current quarter. These improvements were offset by a higher expected loss ratio in the agriculture line to reflect a more challenging start to the growing season in 2013 compared to 2012 resulting from a more challenging winter wheat growing season and excess moisture prevented planting claims for spring crops.

Acquisition Expenses.The Company’s acquisition expense ratios in the Insurance segment in the second quarter and first six months of 2013 decreased compared to the same periods in 2012. The change in the acquisition expense ratio over both periods was driven by a higher proportion of net earned premiums attributed to the agriculture line which incurs a lower net acquisition expense rate and the decline in professional lines premiums over the periods which conversely incurs higher commissions.

General and Administrative Expenses.The increase in general and administrative expenses and expense ratios in the Insurance segment in the second quarter and first six months of 2013 compared to the same periods in 2012 was a result of an increase in personnel costs related to the addition of new underwriting teams over the last twelve months, higher annual incentive costs and increased levels of allocated expenses primarily from increased personnel expenses associated with the Company’s senior leadership transition.

The movements in net premiums written in the Reinsurance segment for the second quarter and six months ended June 30, 2013 compared to the same periods in 2012 were primarily due to the following factors:

• Growth in property premiums which were higher due to new premiums and modest rate increases on renewed business, particularly from the Company’s London, Zurich and Singapore offices;

• Expansion of net written premiums in the other specialty line, primarily due to new business generated by the trade credit and surety team that joined the Company in late 2012, partially offset by an absence of positive premium adjustments compared to 2012 and clients increasing their retentions upon renewal of certain treaties;

• Increased net written premiums within the casualty line as a result of new business written on international motor and U.S. casualty treaties; and

• A decrease in the catastrophe line reflecting the impact of a more competitive market where pricing declined and the Company chose to selectively reduce limits on certain U.S. business, particularly in Florida.

Ceded premiums written by the Company increased in the three and six months ended June 30, 2013 as compared to the same period in 2012 as the Company has chosen to purchase increased levels of protection in the catastrophe and property lines of business.

56

Net premiums earned by the Company in the Reinsurance segment for the three and six months ended June 30, 2013 increased compared to the same period in 2012 due to the growth in gross premiums written in more recent periods.

Losses and Loss Expenses. The net loss ratio in the Company’s Reinsurance segment for the three and six months ended June 30, 2013 decreased compared to the same periods in 2012 as a result of higher levels of prior year reserve development in 2013 compared to 2012. The Company recorded $57.2 million and $90.6 million of favorable prior year loss reserve development in the three and six months ended June 30, 2013 compared to $5.9 million and $15.0 million in the three and six months ended June 30, 2012. During the three and six months ended June 30, 2013, the majority of the favorable loss reserve development emanated from the property and catastrophe lines, driven by reductions in the Thailand flood losses of 2011 and Superstorm Sandy losses in 2012, and from much lower than expected attritional losses. The same periods in 2012 experienced adverse development on some of the major 2011 loss events.

Partially offsetting the increased levels of favorable prior year loss reserve development in the current periods, the Company recorded losses, net of reinstatement premiums and other loss sensitive accruals, of $47.4 million and $47.4 million in the quarter and six months ended June 30, 2013 in relation to European floods, Canadian floods and various U.S. tornado and storm losses. The net losses from these events added 18.8 and 9.5 percentage points to the Reinsurance segment’s net loss ratio for the second quarter and six months ended June 30, 2013, respectively. During the second quarter and six months ended June 30, 2012, the Company incurred losses of $14.4 million and $36.9 million related to the Kentucky and other Midwest windstorms and an Italian earthquake. The net losses from those events added 5.8 and 7.8 percentage points to the Reinsurance segment’s net loss ratio for the second quarter and six months ended June 30, 2012, respectively.

Acquisition Expenses. The Company’s acquisition expense ratio in the Reinsurance segment for the three months ended June 30, 2013 was lower than in the same period in 2012. The change in acquisition ratio for the three month period was due primarily to the growth of the property reinsurance business lines over the last twelve months exhibiting a lower average acquisition expense rate than in prior periods. In the six month period ended June 30, 2013, the acquisition ratio was comparable to the same period in 2012.

General and Administrative Expenses. The general and administrative expense ratios in the Reinsurance segment for the three and six months ended June 30, 2013 increased compared to those in the same periods in 2012 due to an increase in allocated current period costs associated with higher annual incentive costs and the Company’s senior leadership transition, offset partially by the impact of higher earned premiums.

Liquidity and Capital Resources

Endurance Holdings is a holding company that does not have any significant operations or assets other than its ownership of the shares of its direct and indirect subsidiaries. Endurance Holdings relies primarily on dividends and other permitted distributions from its subsidiaries to pay its operating expenses, interest on debt and dividends, if any, on its ordinary shares, its 7.75% Non-Cumulative Preferred Shares, Series A (“Series A Preferred Shares”) and its 7.5% Non-Cumulative Preferred Shares, Series B (“Series B Preferred Shares”). There are restrictions on the payment of dividends by the Company’s operating subsidiaries to Endurance Holdings, which are described in more detail below.

Ability of Subsidiaries to Pay Dividends.The ability of Endurance Bermuda to pay dividends is dependent on its ability to meet the requirements of applicable Bermuda law and regulations. Under Bermuda law, Endurance Bermuda may not declare or pay a dividend if there are reasonable grounds for believing that Endurance Bermuda is, or would after the payment be, unable to pay its liabilities as they become due, or the realizable value of Endurance Bermuda’s assets would thereby be less than the aggregate of its liabilities and its issued share capital and share premium accounts. Further, Endurance Bermuda, as a regulated insurance company in Bermuda, is subject to additional regulatory restrictions on the payment of dividends or distributions. As of June 30, 2013, Endurance Bermuda could pay a dividend or return additional paid-in capital totaling approximately $574.9 million (December 31, 2012 – $623.1 million) without prior regulatory approval based upon the Bermuda insurance and corporate regulations. In 2011, Endurance Holdings loaned Endurance Bermuda $200.0 million, which remains outstanding and is callable on demand.

Endurance U.S. Reinsurance, Endurance American, Endurance American Specialty and Endurance Risk Solutions are subject to regulation by the State of Delaware Department of Insurance and American Agri-Business is subject to regulation by the Texas Department of Insurance. Dividends for each U.S. operating subsidiary are limited to the greater of 10% of policyholders’ surplus or statutory net income, excluding realized capital gains. In addition, dividends may only be declared or distributed out of earned surplus. At December 31, 2012, Endurance U.S. Reinsurance, Endurance American, Endurance Risk Solutions and Endurance American Specialty did not have earned surplus; therefore, these companies are precluded from declaring or distributing dividends at June 30, 2013 without the prior approval of the applicable insurance regulator. At June 30, 2013, American Agri-Business (with notice to the Texas Department of Insurance) could pay dividends of $4.3 million without prior regulatory approval from the applicable regulators. In addition, any dividends paid by Endurance American, Endurance American Specialty and Endurance Risk Solutions would be subject to the dividend limitation of their respective parent insurance companies.

Under the jurisdiction of the United Kingdom’s Prudential Regulation Authority (“PRA”), Endurance U.K. must maintain a margin of solvency at all times, which is determined based on the type and amount of insurance business written. The PRA regulatory requirements impose no explicit restrictions on Endurance U.K.’s ability to pay a dividend, but Endurance U.K. would have to notify the PRA 28 days prior to any proposed dividend payment. Dividends may only be distributed from profits available for distributions. At June 30, 2013, Endurance U.K. did not have profits available for distributions.

Cash and Invested Assets. The Company’s aggregate invested assets, including fixed maturity investments, short-term investments, equity securities, other investments, cash and cash equivalents and pending securities transactions, as of June 30, 2013 totaled $6.4 billion, which is consistent with the aggregate invested assets of $6.6 billion as of December 31, 2012.

At June 30, 2013, the unrealized losses on the Company’s available for sale securities were primarily due to an increase in interest rates and widening of credit spreads, rather than any actual credit losses on these securities. Because the Company has the ability and intent to hold these securities until recovery, the Company currently believes it is probable that it will collect all amounts due according to their respective contractual terms. Therefore, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2013.

The Company’s aggregate direct exposure to the indebtedness and equity securities of those countries whose currency is the Euro or whose sovereign debt rating is below AAA (except the U.S.) was $442.5 million at June 30, 2013, compared to $247.1 million at December 31, 2012. The increase in exposures as of June 30, 2013 compared to December 31, 2012 is mainly due to Moody’s downgrade of the United Kingdom from “Aaa” to “Aa1” in February 2013.

58

In addition to the direct exposures above, the Company has indirect exposure to sovereign and non-sovereign investments whose currency is the Euro or whose sovereign debt rating is below AAA through a hedge fund with a primary focus on European indebtedness, principally focused on benefiting from the declining value of European sovereign indebtedness.

Cash Flows

	(U.S. dollars in thousands)
Net cash provided by operating activities	$	42,712		$	70,295

Cash and cash equivalents, beginning of period		1,124,019			890,914
Cash and cash equivalents, end of period	$	942,062		$	842,180

The decrease in cash flows provided by operating activities in the first half of 2013 compared to the same period in 2012 was primarily due to settlement of agriculture insurance losses incurred in 2012, as well as higher claim payments for catastrophe losses incurred in 2011 and 2012, partially offset by increased premium collections.

The increase in cash used in investing activities reflected the Company’s active management of its investment portfolio on a fair value basis to generate attractive economic returns and income. Movements in financial markets and interest rates influence the timing of investment sales and purchases. The increase in cash flows used in investing activities in 2013 principally reflected reduced proceeds from sales and maturities of available for sale investments partially offset by reduced purchases of available for sale investments compared to 2012.

The cash flows used in financing activities in 2013 were lower than in 2012 principally due to proceeds associated with the issuance of common shares partially offset by repurchases of common shares in 2013.

On May 28, 2013, prior to John R. Charman becoming the Company’s Chairman and Chief Executive Officer, Mr. Charman, together with members of his family, purchased from the Company $30.0 million of newly issued ordinary shares.

During the six months ended June 30, 2013, the Company used its capital to repurchase 318,252 ordinary shares in the open market for $14.6 million at an average price per share of $45.83. During the six months ended June 30, 2012, the Company repurchased $1.0 million of its 6.15% Senior Notes due October 15, 2015.

As of June 30, 2013 and December 31, 2012, the Company had pledged cash and cash equivalents and fixed maturity investments of $203.6 million and $224.4 million, respectively, in favor of certain ceding companies to collateralize obligations. As of June 30, 2013 and December 31, 2012, the Company had also pledged $319.1 million and $380.0 million of its cash and fixed maturity investments to meet collateral obligations for $269.4 million and $320.4 million in letters of credit outstanding under its credit facility, respectively. In addition, at June 30, 2013 and December 31, 2012, cash and fixed maturity investments with fair values of $275.1 million and $280.0 million were on deposit with U.S. state regulators, respectively.

Credit Facility. Under the Company’s credit facility, the Company and its subsidiaries have access to a revolving line of credit of up to $700.0 million, which expires April 19, 2016. As of June 30, 2013, there were no borrowings under this facility and letters of credit outstanding under the facility were $269.4 million.

59

Historically, the operating subsidiaries of the Company have generated sufficient cash flows to meet all of their obligations. Because of the inherent volatility of the business written by the Company, the seasonality in the timing of payments by ceding companies, the irregular timing of loss payments, the impact of a change in interest rates on the Company’s investment returns as well as seasonality in coupon payment dates for fixed maturity investments, cash flows from the Company’s operating activities may vary significantly between periods. The Company expects to continue to generate positive operating cash flows through 2013, absent the occurrence of additional significant loss events. 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 investment portfolio, access its existing credit facility, or arrange for additional financing. However, there can be no assurance that the Company will be successful in executing these strategies.

Currency and Foreign Exchange

The Company’s functional currencies are U.S. dollars for its U.S. and Bermuda operations and British Sterling for its U.K. operations. The reporting currency for all operations is U.S. dollars. The Company maintains a portion of its investments and liabilities in currencies other than the U.S. dollar. The Company has made a significant investment in the capitalization of Endurance U.K, which is subject to the PRA’s rules concerning the matching of the currency of its assets to the currency of its liabilities. Depending on the profile of Endurance U.K.’s liabilities, it may be required to hold some of its assets in currencies corresponding to the currencies of its liabilities. The Company may, from time to time, experience gains or losses resulting from fluctuations in the values of foreign currencies, which could have a material adverse effect on the Company’s results of operations.

Assets and liabilities of foreign operations whose functional currency is not the U.S. dollar are translated at exchange rates in effect at the balance sheet date. Revenues and expenses of such foreign operations are translated at average exchange rates during the year. The effect of the translation adjustments for foreign operations is included in accumulated other comprehensive income.

Other monetary assets and liabilities denominated in foreign currencies are revalued at the exchange rates in effect at the balance sheet date with the resulting foreign exchange gains and losses included in earnings. Revenues and expenses denominated in foreign currencies are translated at the prevailing exchange rate on the transaction date.

Effects of Inflation

The effects of inflation could cause the severity of claims to rise in the future. The Company’s estimates for losses and loss expenses include assumptions about future payments for settlement of claims and claims handling expenses, such as medical treatments and litigation costs. To the extent inflation causes these costs to increase above reserves established for these claims, the Company will be required to increase the reserve for losses and loss expenses with a corresponding reduction in its earnings in the period in which the deficiency is identified. In addition, inflation could lead to higher interest rates causing the current unrealized gain position on the Company’s fixed maturity portfolio to decrease or become an unrealized loss position. In response, the Company may choose to hold its fixed income investments to maturity, which would result in the unrealized gains largely amortizing through net investment income.

• the ability to maintain the availability of our systems and safeguard the security of our data in the event of a disaster or other unanticipated event; and

• changes in general economic conditions, including inflation, foreign currency exchange rates, interest rates, and other factors.

The foregoing review of important factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in our 2012 Form 10-K, including the risk factors set forth in Item 1A thereof.
