1.   History and Organization

Aspen Insurance Holdings Limited (“Aspen Holdings”) was incorporated on May 23, 2002 and holds subsidiaries that provide insurance and reinsurance on a worldwide basis. Its principal operating subsidiaries are Aspen Insurance UK Limited (“Aspen U.K.”), Aspen Insurance Limited (“Aspen Bermuda”), Aspen Specialty Insurance Company (“Aspen Specialty”) and Aspen Underwriting Limited (corporate member of Lloyd’s Syndicate 4711, “AUL”), (collectively, the “Insurance Subsidiaries”).

2.   Basis of Preparation

The accompanying unaudited condensed consolidated financial statements have been prepared on the basis of generally accepted accounting principles in the United States (“GAAP”) for interim financial information and in accordance with the instructions toForm 10-Q and Article 10 ofRegulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP 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 nine months ended September 30, 2009 are not necessarily indicative of the results that may be expected for the year ended December 31, 2009. The unaudited condensed consolidated financial statements include the accounts of Aspen Holdings and its wholly-owned subsidiaries, which are collectively referred to herein as the “Company.” All intercompany transactions and balances have been eliminated on consolidation.

The balance sheet at December 31, 2008 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP 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, 2008 contained in Aspen’s Annual Report onForm 10-K filed with the United States Securities and Exchange Commission (FileNo. 001-31909).

Assumptions and estimates made by management have a significant effect on the amounts reported within the consolidated financial statements. The most significant of these relate to the losses and loss adjustment expenses, the value of investments, reinsurance recoverables and the fair value of derivatives. All material assumptions and estimates are regularly reviewed and adjustments made as necessary, but actual results could be significantly different from those expected when the assumptions or estimates were made.

New Accounting Pronouncements Adopted in 2009

In June 2009, the Financial Accounting Standards Board (“FASB”) issued Statement No. 168“The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles – a replacement of FASB Statement No. 162”(“the Codification”). The Codification establishes the FASB Accounting Standards Codification (“ASC”) as the source of authoritative accounting principles to be applied in preparation of financial statements in accordance with GAAP. The Codification supersedes all existing U.S. accounting standards; all other accounting literature not included in the Codification (other than Securities and Exchange Commission guidance for publicly traded companies) is considered non-authoritative. The Codification was effective on a prospective basis for interim and annual reporting periods ending after September 15, 2009. The adoption of the Codification changed the Company’s references to U.S. GAAP accounting standards but did not impact the consolidated results of operations, financial condition or cash flows for the nine months ended September 30, 2009.

In May 2009, the FASB issued new guidance for accounting for subsequent events. The new guidance which is now part of ASC 855Subsequent Events, requires disclosures of the date through which subsequent events have been evaluated and whether that date is the date the financial statements were issued or the date the financial statements were available to be issued. Additionally, the guidance replaces Type 1 and Type 2 subsequent events with recognized and

9

non-recognized subsequent events. The guidance requires prospective application and is effective for interim and annual periods ending after June 15, 2009. The adoption of the new guidance requires additional disclosures and has not had an impact on the consolidated results of operations, financial condition or cash flows for the nine months ended September 30, 2009.

In April 2009, the FASB issued new guidance related to the disclosure of the fair value of financial instruments. The new guidance, which is now part of ASC 825Financial Instruments, requires disclosures about the fair value of financial instruments in interim financial statements as well as in annual financial statements. Additionally, the new guidance requires disclosure of the methods and significant assumptions used to estimate the fair value of financial instruments on an interim basis as well as changes of the methods and significant assumptions from prior periods. It does not change the accounting treatment for these financial instruments. The provisions of the new guidance have not had an impact on the consolidated financial statements for the three or nine months ended September 30, 2009.

In April 2009, the FASB issued new guidance for determining when a market is not orderly and for estimating fair market value when the volume or level of activity for the asset or liability has significantly decreased. The new guidance, which is now part of ASC 820Fair Value Measurements and Disclosures,was effective for interim periods ending after June 15, 2009. The adoption of the new guidance has not had an impact on the consolidated financial statements for the three or nine months ended September 30, 2009.

In April 2009, the FASB issued new guidance for the accounting forother-than-temporary impairments. Under the new guidance, which is now part of ASC 320Investments — Debt and Equity Securities, debt securities where the amortized cost is greater than the fair market value shall be assessed to determine if the impairment isother-than-temporary. If a company intends to sell a security (that is, it has decided to sell the security) or it is more likely than not that it will be required to sell a security prior to recovery of its cost basis, a security would be written down to fair value with the full charge recorded in earnings. If a company does not intend to sell a security and it is not more likely than not that it will be required to sell the security prior to recovery, the amount ofother-than-temporary impairment related to credit losses would be recognized in earnings. Any remaining difference between the fair value and the cost basis would be recognized as part of other comprehensive income. The adoption of the new guidance has not had a material impact on the consolidated financial statements for the three or nine months ended September 30, 2009.

In May 2008, the FASB issued new guidance for the accounting for financial guarantee insurance contracts. Under the new guidance, which is now part of ASC 944Financial Services — Insurance, an insurance enterprise is required to recognize a claim liability prior to an event of default when there is evidence that credit deterioration has occurred in an insured financial obligation. The guidance also clarifies recognition and measurement for premium revenue and claim liabilities. It is effective for fiscal years beginning after December 15, 2008, and all interim periods within the fiscal year except for some disclosures about the insurance enterprise’s risk management activities. The adoption of the new guidance has not had an impact on the consolidated financial statements for the three or nine months ended September 30, 2009.

In March 2008, the FASB issued new guidance on the disclosure of derivative instruments and hedging activities. The new guidance, which is now part of ASC 815Derivatives and Hedging Activities, changes the disclosure requirements for derivative instruments and hedging activities. Entities are required to provide enhanced disclosures about (a) how and why an entity uses derivative instruments, (b) how derivative instruments and related hedged items are accounted for and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. The guidance requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The Company adopted the disclosures required by the new guidance in the first quarter of 2009. The provisions of the new

10

guidance only required additional disclosure which did not have an impact on the consolidated results of operations, financial condition or cash flows.

Accounting standards not yet adopted

In August 2009, the FASB issued new guidance for the accounting for the fair value measurement of liabilities. The new guidance, which is now part of ASC 820Fair Value Measurements and Disclosures, provides clarification that in certain circumstances in which a quoted price in an active market for the identical liability is not available, a company is required to measure the fair value using one or more of the following techniques: the quoted price of the identical liability when traded as an asset and the quoted prices for similar liabilities, or similar liabilities when traded as assets or another valuation technique that is consistent with the principles of ASC 820. The new guidance is effective for interim and annual periods beginning after August 27, 2009. The Company does not expect that the provisions of the new guidance will have an impact on the Company’s consolidated financial statements.

In June 2009, the FASB issued revised guidance on the accounting for variable interest entities. The revised guidance which was issued as Statement No. 167,“Amendments to FASB Interpretation No. 46R” has not yet been adopted into the Codification. The revised guidance replaces the quantitative approach previously required for determining the primary beneficiary of a variable interest entity with an approach focused on the power to direct activities that significantly impact an entity’s economic performance and the obligation to absorb losses of the entity or the right to receive benefits from the entity. It also requires ongoing assessment of whether an enterprise is a variable interest entity. The statement is effective for each annual reporting period that begins after November 15, 2009. The Company is currently evaluating the impact, if any, that the provisions of the revised guidance will have on its consolidated financial statements.

In June 2009, the FASB issued new guidance on the accounting for the transfer of financial assets. The new guidance, which was issued as Statement No. 166,“Accounting For Transfers of Financial Assets – an amendment of FASB Statement No. 140” has not yet been adopted into the Codification. The new guidance eliminates the concept of a qualifying special purpose entity and therefore any qualifying special purpose entities in existence before the effective date will need to be evaluated for consolidation. The criteria for reporting a transfer of financial assets has also changed. The guidance is effective on a prospective basis on January 1, 2010 and interim and annual periods thereafter. The Company does not expect that the provisions of the new guidance will have an impact on the Company’s consolidated financial statements.

3.   Earnings Per Ordinary Share

Basic earnings per ordinary share are calculated by dividing net income available to holders of Aspen’s ordinary shares by the weighted average number of ordinary shares outstanding. Diluted earnings per ordinary share are based on the weighted average number of ordinary shares and dilutive potential ordinary shares outstanding during the period of calculation using the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2009 and 2008, respectively:

Purchase of preference shares.  On March 31, 2009, we purchased 2,672,500 of our 7.401% $25 liquidation price preference shares (NYSE: AHL-PA) at a price of $12.50 per share. The purchase resulted in a first quarter gain of approximately $31.5 million, net of a non-cash charge of $1.2 million reflecting the write off of the pro-rata portion of the original issuance costs of the 7.401% preference shares.

4.   Segment Reporting

The Company has four reportable business segments: property reinsurance; casualty reinsurance; international insurance; and U.S. insurance. The Company has considered similarities in economic characteristics, products, customers, distribution, and the regulatory environment of the Company’s operating segments and quantitative thresholds to determine the Company’s reportable segments.

Property Reinsurance.  Our property reinsurance segment is written on both a treaty and facultative basis and consists of the following principal lines of business: treaty catastrophe, treaty risk excess, treaty pro rata, and property facultative. Treaty reinsurance contracts provide for automatic coverage of a type or category of risk underwritten by our ceding clients. We also write some structured reinsurance contracts out of Aspen Bermuda. These contracts are tailored to the individual client circumstances and although written by a single team are accounted for within the business segment that best reflects the economic characteristics of the contract. We also include within this segment credit, surety and political risk reinsurance contracts written by the Zurich branch of Aspen U.K. This portfolio is written principally on a treaty basis.

Casualty Reinsurance.  Our casualty reinsurance segment is written on both a treaty and facultative basis and consists of the following principal lines of business: U.S. treaty, international treaty, and casualty facultative. The casualty treaty reinsurance we write includes excess of loss and pro rata reinsurance which are applied to portfolios of primary insurance policies. Our excess of loss positions come most commonly from layered reinsurance structures with underlying ceding company retentions. We also write some structured reinsurance contracts.

International Insurance.  Our international insurance segment consists of the following principal lines of business: U.K. commercial property and construction, U.K. commercial liability, excess casualty (which now includes non-marine and transportation liability), professional liability, marine hull, energy property damage, marine, energy and construction liability, aviation, financial institutions, management and technology liability, specie, financial and political risk insurance and specialty reinsurance written principally by Aspen U.K. and our Lloyd’s operations, Syndicate 4711. Specialty reinsurance consists of marine and aviation reinsurance as well as terrorism, nuclear, personal accident, crop and satellite. Our international insurance lines are written on a primary and excess of loss basis and our specialty reinsurance is written on both a treaty pro rata and excess of loss basis.

U.S. Insurance.  Our U.S. insurance segment consists principally of property and casualty insurance written on an excess and surplus lines basis. We also write property insurance that provides lead underwriting support to a select group of U.S. program managers. This is referred to as our risk solutions business.

We do not allocate our assets by segment as we evaluate underwriting results of each segment separately from the results of our investment portfolio. Segment profit or loss for each of the Company’s operating segments is measured by underwriting profit or loss. Underwriting profit or loss provides a basis for management to evaluate the segment’s underwriting performance.

As at September 30, 2009, the Company held 138 fixed maturities (December 31, 2008 — 634 fixed maturities) in an unrealized loss position with a fair value of $251.0 million (December 31, 2008 — $1,061.8 million) and gross unrealized losses of $8.0 million (December 31, 2008 — $103.0 million). The Company believes that the gross unrealized losses are attributable mainly to a combination of widening credit spreads and interest rate movements and has concluded that the period of those investments in an unrealized loss position is temporary.

Other-than-temporary impairments.  The Company recordedother-than-temporary impairments for the three and nine months ended September 30, 2009 of $1.8 million (2008 — $55.8 million) and $19.9 million (2008 — $55.8 million), respectively. We review all of our investments in fixed maturities designated available for sale for potential impairment each quarter based on criteria including issuer-specific circumstances, credit ratings actions and general macro-economic conditions. The process of determining whether a decline in value is“other-than-temporary” requires considerable judgment. As part of the assessment process we evaluate whether it is more likely than not that we will sell any fixed maturity security in an unrealized loss position before its market value recovers to amortized cost. Once a security has been identified asother-than-temporarily impaired, the amount of any impairment included in net income is determined by reference to that portion of the unrealized loss that is considered to be credit related. Non-credit related unrealized losses are included in other comprehensive income.Other-than-temporary impairment is discussed further in Note 2 of the unaudited condensed consolidated financial statements.

Other investments.  Other investments as at September 30, 2009 and December 31, 2008 are as follows:

	September 30, 2009				December 31, 2008
	Cost		Carrying Value		Cost		Carrying Value

Total other investments	$	25.0	$	25.9	$	311.3	$	286.9

Investment funds.  Investment funds represented our investments in funds of hedge funds which were recorded using the equity method of accounting. Adjustments to the carrying value of these investments were made based on the net asset values reported by the fund managers, resulting in a carrying value that approximated fair value. Realized and unrealized gains of $Nil (2008 — loss of $42.2 million) and $20.2 million (2008 — loss of $48.3 million) were recognized through the statement of operations in the three and nine months ended September 30, 2009, respectively. We invested $150.0 million in the share capital of two funds in 2006, a further $247.5 million in one of these funds and $112.5 million in the

21

share capital of a third fund in 2007. In 2008, we sold share capital in the funds that cost $198.6 million for proceeds of $177.2 million realizing a loss of $21.4 million. In February 2009, we gave notice to redeem the balance of the funds in June 2009. As a result, we recognized proceeds from the redemption of funds of $307.1 million at June 30, 2009.

The Company’s involvement with the funds ceased at June 30, 2009. The carrying value of the receivables represents the Company’s maximum exposure to loss at the balance sheet date. Of the $16.3 million receivable at September 30, 2009, $4.8 million was received by October 31, 2009 with the remaining balance of $11.5 million to be received subsequent to the completion of the audited financial statements for the fund.

Cartesian Iris 2009A.  On May 19, 2009, Aspen Holdings invested $25 million in Cartesian Iris 2009A L.P. through our wholly owned subsidiary, Acorn Limited. Cartesian Iris 2009A L.P. is a Delaware Limited Partnership formed to provide capital to Iris Re, a newly formed Class 3 Bermudian reinsurer focusing on insurance linked securities. In addition to the investment in Cartesian Iris 2009A L.P., Aspen provides certain underwriting and actuarial services in return for a percentage of profits from Iris Re. In the three and nine months ended September 30, 2009, a fee of $0.1 million was payable to Aspen.

The Company accounts for its investment in accordance with the equity method of accounting. Adjustments to the carrying value of this investment are made based on the Company’s share of capital including its share of income and expenses, which is provided in the quarterly management accounts of the partnership. The adjusted carrying value approximates fair value. In the three and nine months ended September 30, 2009, the Company’s share of gains and losses increased the value of our investment by $1.2 million (2008-$Nil) and $0.9 million (2008-$Nil), respectively. The increase in value has been recognized in realized and unrealized gains and losses in the condensed consolidated statement of operations. For more information see Note 12(c).

The Company’s involvement with Cartesian Iris 2009A L.P. is limited to its investment in the partnership and it is not committed to making further investments in Cartesian Iris 2009A L.P.; accordingly, the carrying value of the investment represents the Company’s maximum exposure to a loss as a result of its involvement with the partnership at each balance sheet date.

6.   Fair Value Measurements

The Company’s estimates of fair value for financial assets and liabilities are based on the framework established in the fair value accounting guidance. The framework prioritizes the inputs, which refer broadly to assumptions market participants would use in pricing an asset or liability, into three levels, which are described in more detail below.

The Company considers prices for actively traded Treasury securities to be derived based on quoted prices in active markets for identical assets, which are Level 1 inputs in the fair value hierarchy. The Company considers prices for other securities priced via vendors, indices, or broker-dealers to be derived based on inputs that are observable for the asset, either directly or indirectly, which are Level 2 inputs in the fair value hierarchy.

The Company considers securities, other financial instruments and derivative insurance contracts subject to fair value measurement whose valuation is derived by internal valuation models to be based largely on unobservable inputs, which are Level 3 inputs in the fair value hierarchy. There have been no changes in the Company’s use of valuation techniques during the year.

Our fixed income securities are traded on theover-the-counter market, based on prices provided by one or more market makers in each security. Securities such as U.S. Government, U.S. Agency, Foreign Government and investment grade corporate bonds have multiple market makers in addition to readily observable market value indicators such as expected credit spread, except for Treasury securities, over the yield curve. We use a variety of pricing sources to value our fixed income securities including those securities that have pay down/prepay features such as mortgage-backed securities and asset-backed securities in order to ensure fair and accurate pricing. The fair value estimates of the investment grade securities in our portfolio do not use significant unobservable inputs or modeling techniques.

The following table presents the table within the fair value hierarchy at which the Company’s financial assets are measured on a recurring basis at September 30, 2009.

Fixed income maturities classified as Level 3 include holdings where there are significant unobservable inputs in determining the assets’ fair value and also securities of Lehman Brothers Holdings, Inc. (“Lehman Brothers”). Although the market value of Lehman Brothers bonds was based on broker dealer quoted prices, management believes that the valuation is based, in part, on market expectations of future recoveries out of bankruptcy proceedings, which involve significant unobservable inputs to the valuation. Derivatives at fair value consist of the credit insurance contract as described in Note 8.

7.   Reinsurance

We purchase retrocession and reinsurance to limit and diversify our own risk exposure and to increase our own insurance underwriting capacity. These agreements provide for recovery of a portion of losses and loss expenses from reinsurers. As is the case with most reinsurance treaties, we remain liable to the extent that reinsurers do not meet their obligations under these agreements, and therefore, in line with our risk management objectives, we evaluate the financial condition of our reinsurers and monitor concentrations of credit risk. In addition, we have entered into reinsurance agreements and derivative instruments as described below:

Ajax Re.  On April 25, 2007, we entered into a reinsurance agreement that provided us with coverage incepting on August 18, 2007. Under the reinsurance agreement, Ajax Re Limited (“Ajax Re”) provided us with $100 million of aggregate indemnity protection for certain losses from individual earthquakes in California occurring between August 18, 2007 and May 1, 2009. The reinsurance agreement was fully collateralized by proceeds received by Ajax Re from the issuance of catastrophe bonds. The amount of the recovery was limited to the lesser of our losses and the proportional amount of $100 million based on the Property Claims Services (“PCS”) reported losses and the attachment level of $23.1 billion and the exhaustion level of $25.9 billion. For further information, see Note 12(c). At the balance sheet date and at expiry of the contract on May 1, 2009, no recovery was due from Ajax Re.

In order to ensure that Ajax Re had sufficient funding to service the LIBOR portion of interest due on the bonds issued by Ajax Re, Ajax Re entered into a total return swap (the “swap”) with Lehman Brothers Special Financing, Inc. (“Lehman Financing”), whereby Lehman Financing directed Ajax Re to invest the proceeds from the bonds into permitted investments. Lehman Brothers also provided a guarantee of Lehman Financing’s obligations under the swap.

On September 15, 2008, Lehman Brothers filed for bankruptcy, which is a termination event under the swap. Ajax Re terminated the swap on September 16, 2008. Nevertheless, Aspen remained within its risk tolerances during the period of cover without benefit of this reinsurance.

Foreign Exchange Contract	Net Foreign Exchange Gains and Losses	$	—		$	(3.8	)

Credit insurance contract.  On November 28, 2006, the Company entered into a credit insurance contract which, subject to its terms, insures the Company against losses due to the inability of one or more of our reinsurance counterparties to meet their financial obligations to the Company.

The Company considers the contract to be a derivative instrument because the final settlement is expected to take place two years after expiry of cover and include an amount attributable to outstanding and IBNR claims which may not at that point in time be due and payable to the Company.

As a result of the application of derivative accounting guidance, the contract is treated as an asset or a liability and measured at the directors’ estimate of its fair value. Changes in the estimated fair value from time to time will be included in the consolidated statement of operations.

The contract is for a maximum of five years and provides 90% cover for a named panel of reinsurers up to individual definedsub-limits. The contract does allow, subject to certain conditions, for substitution

26

and replacement of panel members if the Company’s panel of reinsurers changes. Payments are made on a quarterly basis throughout the period of the contract based on the aggregate limit, which was set initially at $477 million but is subject to adjustment. The carrying value of the derivative is the Company’s maximum exposure to loss.

Foreign exchange contract.  The Company uses forward exchange contracts to manage foreign currency risk. A forward foreign currency exchange contract involves an obligation to purchase or sell a specified currency at a future date at a price set at the time of the contract. Foreign currency exchange contracts will not eliminate fluctuations in the value of our assets and liabilities denominated in foreign currencies but rather allow us to establish a rate of exchange for a future point in time. The foreign currency contracts are recorded as derivatives at fair value with changes recorded as a net foreign exchange gain or loss in the Company’s statement of operations.

9.   Reserves for Losses and Adjustment Expenses

The following table represents a reconciliation of beginning and ending consolidated loss and loss adjustment expenses (“LAE”) reserves:

	As at			As at
	September 30, 2009			December 31, 2008

Total paid		(620.5	)		(739.4	)
Foreign exchange losses (gains)		103.4			(219.0	)
Net losses and LAE reserves at period end		2,980.5			2,787.0
Plus reinsurance recoverable on unpaid losses at period end		333.5			283.3
Loss and LAE reserves at September 30, 2009 and December 31, 2008	$	3,314.0		$	3,070.3

For the nine months ended September 30, 2009, there were reserve releases of $71.0 million compared to $95.6 million for the nine months ended September 30, 2008 in our estimate of the ultimate claims to be paid in respect of prior accident years.

The net loss and loss expenses disposed of represents reductions in reserves for several Lloyd’s syndicates which we originally assumed under reinsurance to close arrangements accounted for by the syndicates prior to 2007.

Total issued share capital				141				142
Additional paid-in capital ($ in millions)			$	1,760.6			$	1,754.8

Additional paid-in capital includes the aggregate liquidation preferences of our preference shares of $363.2 million (2008 — $430.0 million) less issue costs of $9.6 million (2008 — $10.8 million).

Purchase of preference shares.  On March 31, 2009, we purchased 2,672,500 of our 7.401% $25 liquidation price preference shares (NYSE : AHL-PA) at a price of $12.50 per share. For earnings per share purposes, the purchase resulted in a first quarter gain of approximately $31.5 million, net of a non-cash charge of $1.2 million reflecting the write off of the pro-rata portion of the original issuance costs of the 7.401% preference shares.

Ordinary Shares.  The following table summarizes transactions in our ordinary shares during the nine month period ended September 30, 2009.

11.   Share Based Payments

The Company has issued options and other equity incentives under four arrangements: investor options, employee awards, non-employee director awards and the employee share purchase plans. When options are exercised or other equity awards have vested, new shares are issued as the Company does not currently hold treasury shares. The Company applies a fair-value based measurement method and an estimate of future forfeitures in the calculation of the compensation costs of stock options and restricted share units.

Investor Options.  The investor options were issued on June 21, 2002 to Wellington Investment Holdings (Jersey) Limited (“Wellington Investment”) and members of Syndicate 2020 who were not corporate members of Syndicate 2020. The options conferred to the members of Syndicate 2020 are held for their benefit by Appleby Services (Bermuda) Ltd. (formerly Appleby Trust (Bermuda) Limited) (“Names’ Trustee”). The subscription price payable under the options is initially £10 and increases by 5% per annum, less any dividends paid. Option holders are not entitled to participate in any dividends prior to exercise and would not rank as a creditor in the event of liquidation. If not exercised, the options will expire on June 21, 2012. Wellington Investment exercised all of its options on March 28, 2007.

During the three and nine months ended September 30, 2009, the Names’ Trustee exercised 627 options and 4,469 options on a cash and cashless basis, respectively (2008 — 2,868 and 17,391, respectively).

Employee and Non-Executive Director awards.  Employee options and other awards are granted under the Aspen 2003 Share Incentive Plan and non-executive director awards are granted under the 2006 Stock Option Plan for Non-Employee Directors.

Stock options are granted with an exercise price equivalent to the fair value of the share on the grant date. The weighted average value at grant date is determined using the Black-Scholes option pricing model. Stock options typically vest over a three-year period with a ten-year contract period (except for options granted in 2007 which have a7-year exercise period) with vesting dependent on time and performance conditions established at the time of grant. No options were granted during 2009. However, 106,166 and 164,625 options were exercised in the three and nine months ended September 30, 2009.

Compensation costs charged against income in respect of employee options for the three and nine months ended September 30, 2009 were $0.5 million and $1.6 million, respectively (2008 — $1.1 million and $3.1 million).

Restricted share units (“RSU’s”) to employees vest equally over a two or three-year period. Some of the grants vest at year-end, while some other grants vest on the anniversary of the date of grant. The fair value of the restricted share units is based on the closing price on the date of the grant. The fair value is expensed through the income statement evenly over the vesting period. During the three and nine months ended September 30, 2009, the Company granted to employees nil and 42,291 restricted share units, respectively. In the case of non-employee directors (other than the Chairman whose RSU’s vest annually over a three-year period), one-twelfth of the RSU’s vest on each one month anniversary of the date of grant, with 100% of the RSU’s becoming vested on the first anniversary of the date of grant. During the three and nine months ended September 30, 2009, the Company granted to non-employee directors nil and 33,755 restricted share units, respectively.

Compensation costs charged against income in respect of restricted share units for the three and nine months ended September 30, 2009 were $0.7 million and $2.1 million, respectively (2008 — $1.0 million and $2.1 million).

29

The fair value of performance share awards is based on the value of the average of the high and low of the share price on the date of the grant less a deduction for expected dividends which would not accrue during the vesting period. Performance shares vest over a three or four-year period with shares eligible for vesting dependent on the achievement of performance targets at the end of specified periods as established at the time of grant. For the three and nine months ended September 30, 2009, the Company granted nil and 912,919 performance shares, respectively.

Compensation costs charged against income in the three and nine months ended September 30, 2009 in respect of performance shares were $5.5 million and $11.9 million, respectively (2008 — $0.6 million credit and $3.7 million charge).

Employee Share Purchase Plans.  On April 30, 2008, the shareholders of the Company approved the Employee Share Purchase Plan (the “ESPP”), the U.K. Sharesave Plan and the international plan, which are implemented by a series of consecutive offering periods as determined by the Board. In respect of the ESPP, employees can save up to $500 per month over a two-year period, at the end of which they will be eligible to purchase Company shares at a discounted price. In respect of the U.K. Sharesave Plan, employees can save up to £250 per month over a three-year period, at the end of which they will be eligible to purchase Company shares at a discounted price. The purchase price will be eighty-five percent (85%) of the fair market value of a share on the offering date which may be adjusted upon changes in capitalization of the Company. No shares were issued under the plan during 2008 or 2009.

12.   Commitments and Contingencies

(a)   Restricted assets

We are obliged by the terms of our contractual obligations to U.S. policyholders and by undertakings to certain regulatory authorities to facilitate the issue of letters of credit or maintain certain balances in trust funds for the benefit of policyholders.

The following table shows the forms of collateral or other security provided to policyholders as at September 30, 2009 and December 31, 2008.

(1)	These letters of credit are not secured by cash or securities, though we have the ability to issue secured letters of credit under the revolving credit facility
(2)	As of September 30, 2009, the Company had funds on deposit of $588.7 million and £21.2 million (December 31, 2008 — $604.6 million and £25.3 million) as collateral for the secured letters of credit.

Funds at Lloyd’s.  AUL operates in Lloyd’s as the corporate member for Syndicate 4711. Lloyd’s determines Syndicate 4711’s required regulatory capital principally based on the syndicate’s annual business plan. Such capital, called Funds at Lloyd’s, comprises: cash, investments and a fully collateralized letter of credit. The amounts of cash, investments and letter of credit at September 30, 2009 amount to $212.6 million (December 31, 2008 — $200.3 million).

(c)   Variable interest entities

Ajax Re.  As disclosed in Note 7, we entered into a reinsurance agreement with Ajax Re that provided the Company with $100 million of aggregate indemnity protection for certain losses from individual earthquakes in California occurring between August 18, 2007 and May 1, 2009.

Ajax Re was a special purpose Cayman Islands exempted company licensed as a restricted Class B reinsurer in the Cayman Islands and formed solely for the purpose of entering into certain reinsurance agreements and other risk transfer agreements with subsidiaries of Aspen to provide up to $1 billion of reinsurance protection covering various perils, subject to Ajax Re’s ability to raise the necessary capital.

The Company has determined that Ajax Re had the characteristics of a variable interest entity that are addressed by the guidance included in ASC 810,Consolidation.As a result, Ajax Re was not consolidated because the majority of the expected losses and expected residual returns would not be absorbed by the Company but rather by the bond holders of Ajax Re.

Cartesian Iris 2009A L.P.  As disclosed in Note 5, on May 19, 2009, Aspen Holdings invested $25 million in Cartesian Iris 2009A L.P. through our wholly owned subsidiary, Acorn Limited. Cartesian Iris 2009A L.P. is a Delaware Limited Partnership formed to provide capital to Iris Re, a newly formed Class 3 Bermudian reinsurer focusing on insurance linked securities. In addition to the investment in Cartesian Iris 2009A L.P., Aspen provides certain underwriting and actuarial services in return for a percentage of profits. In the three and nine months ended September 30, 2009, a fee of $0.1 million was payable to Aspen. The Company’s investment in Cartesian Iris 2009A L.P. represents 31.25% of the equity invested in the partnership.

The Company has determined that Cartesian Iris 2009A L.P. has the characteristics of a variable interest entity that are addressed by the guidance in ASC 810,Consolidation. As a result, Cartesian Iris 2009A L.P. is not consolidated because the majority of the expected losses and expected residual returns will not be absorbed by the Company. The Company has no decision-making power, those powers having been reserved for the general partner.

The Company’s involvement with Cartesian Iris 2009A L.P. is limited to its investment in the partnership and it is not committed to making further investments in Cartesian Iris 2009A L.P.; accordingly, the carrying value of the investment represents the Company’s maximum exposure to a loss as a result of its involvement with the partnership at each balance sheet date.

Item 2.   Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is a discussion and analysis of our financial condition and results of operations for the three and nine months ended September 30, 2009 and 2008. This discussion and analysis should be read in conjunction with the unaudited condensed consolidated financial statements and related notes contained in thisForm 10-Q and the audited consolidated financial statements and related notes for the fiscal year ended December 31, 2008, as well as the discussions of critical accounting policies, contained in our Financial Statements in our 2008 Annual Report onForm 10-K filed with the United States Securities and Exchange Commission.

Some of the information contained in this discussion and analysis or set forth elsewhere in thisForm 10-Q, including information with respect to our plans and strategy for our business and in “Outlook and Trends” below, includes forward-looking statements that involve risk and uncertainties. Please see the section captioned “Cautionary Statement Regarding Forward-Looking Statements” in this report and the “Risk Factors” in Item 1A of our 2008 Annual Report onForm 10-K for more information on factors that could cause actual results to differ materially from the results described in or implied by any forward-looking statements contained in this discussion and analysis.

Recent Developments

On October 6, 2009, Aspen U.K. and Aspen Bermuda entered into a $200 million secured letter of credit facility with Barclays Bank plc. All letters of credit issued under the facility will be used to support reinsurance obligations of the parties to the agreement and their respective subsidiaries.

Overview

We are a Bermuda holding company. We write insurance and reinsurance business through our wholly-owned subsidiaries in three major jurisdictions: Aspen U.K. and AUL, corporate member of Syndicate 4711 at Lloyd’s of London (United Kingdom), Aspen Bermuda (Bermuda) and Aspen Specialty (United States). Aspen U.K. also has branches in Paris, France; Zurich, Switzerland; Dublin, Ireland; Singapore; Australia; and Canada. We operate in global markets for property and casualty insurance and reinsurance.

The most significant features of our results for the three and nine months ended September 30, 2009 were:

•  Net income after tax for the three months ended September 30, 2009 of $145.8 million, compared with a net loss after tax of $126.1 million for the third quarter of 2008. For the nine months ended September 30, 2009, net income after tax was $347.6 million compared to $82.0 million for the same period last year.

•  A combined ratio of 80.3% for the three months ended September 30, 2009 versus 123.3% for the three months ended September 30, 2008;

•  Third quarter net investment income of $58.9 million, up 205.2% over the same quarter last year and down 18.4% over the second quarter of 2009;

•  Diluted earnings per ordinary share after preference share dividends of $1.63 for the three months ended September 30, 2009 increased by $3.26 over the comparative period in 2008. Diluted earnings per ordinary share after preference share dividends was $4.25 for the nine months ended September 30, 2009, an increase of 498.6% compared to the same period last year; and

32

•  Tangible book value per ordinary share at September 30, 2009 was $34.30, an increase of 26.4% compared to $27.14 at September 30, 2008.

Tangible book value per ordinary share is based on total shareholders’ equity, less intangible assets and preference shares (liquidation preference less issue expenses), divided by the number of ordinary shares in issue at the end of the period.

Shareholders’ equity and ordinary shares in issue as at September 30, 2009 and September 30, 2008 were:

	As at			As at
	September 30, 2009			September 30, 2008
	($ in millions, except for share amounts)
Total shareholders’ equity	$	3,212.1		$	2,637.6
Intangible assets		(8.2	)		(8.2	)
Preference shares less issue expenses		(353.6	)		(419.2	)
Net tangible assets attributable to ordinary shareholders	$	2,850.3		$	2,210.2
Ordinary shares		83,094,615			81,450,413
Diluted ordinary shares		86,192,623			84,325,027

The following overview of our results for the three months ended September 30, 2009 and 2008 and of our financial condition at September 30, 2009, is intended to identify important trends and should be read in conjunction with the more detailed discussion further below.

Gross written premiums.  Total gross written premiums increased by 11.1% to $490.3 million in the third quarter of 2009 when compared to 2008 with the increase attributable mainly to property and casualty reinsurance segments.. The table below shows our gross written premiums for each segment for the three months ended September 30, 2009 and 2008, and the percentage change in gross written premiums for each segment.

	For the Three Months					For the Three Months
Business Segment	Ended September 30, 2009					Ended September 30, 2008
	($ in millions)		% increase/			($ in millions)
			(decrease)
Property reinsurance	$	171.2		12.0	%	$	152.8
Casualty reinsurance		96.5		21.1			79.7
International insurance		183.9		1.7			180.8
U.S. insurance		38.7		38.2			28.0
Total	$	490.3		11.1	%	$	441.3

Gross written premiums for the quarter have increased to $490.3 million from $441.3 million in the third quarter of 2008 due mainly to increased contributions from our property reinsurance and casualty reinsurance segments. The casualty reinsurance segment has benefited principally from $13.0 million of premium adjustments, particularly in our U.S. treaty business. The property reinsurance segment has benefited from a $27.3 million contribution from the newly established credit, surety and political risk business line compensating for reductions in premiums written in our treaty risk excess business line. Our U.S. insurance segment has also experienced growth in the quarter particularly in the property line due mainly to new business subsequent to the reshaping of the portfolio in 2008 and increased prices forcatastrophe-exposed business. Gross written premiums in the international insurance segment have increased marginally by 1.7% to $183.9 million when compared to the third quarter of 2008 due to a $4.7 million contribution from the specie and management and technology liability business lines which commenced underwriting after the third quarter of 2008, compensating for a small net reduction in premiums written in the other business lines.

33

Reinsurance.  Total reinsurance ceded for the quarter of $28.2 million has decreased by $9.3 million from the third quarter of 2008. Ceded written premiums in the third quarter of 2008 included $7.4 million of reinstatement premiums in relation to Hurricanes Ike and Gustav.

Loss ratio.  We monitor the ratio of losses and loss adjustment expenses to net earned premium (the “loss ratio”) as a measure of relative underwriting performance where a lower ratio represents a better result than a higher ratio. The loss ratios for our four business segments for the three months ended September 30, 2009 and 2008 were as follows:

	For the Three Months			For the Three Months
Business Segment	Ended September 30, 2009			Ended September 30, 2008
Property reinsurance		25.9	%		118.6	%
Casualty reinsurance		63.0	%		67.2	%
International insurance		60.3	%		89.4	%
U.S. insurance		47.4	%		130.1	%
Total Loss Ratio		49.9	%		95.2	%

The loss ratio for the quarter of 49.9% has decreased by 45.3 percentage points compared to the third quarter of 2008 mainly due to the hurricane losses incurred in 2008 with no comparable events in the third quarter of 2009. The property reinsurance loss ratio of 25.9% is 92.7 percentage points below the third quarter of 2008 due mainly to the absence of catastrophes but also due to $19.1 million of prior year reserve releases in the quarter compared to a $3.3 million release in the third quarter of 2008.

The underlying changes in accident year loss ratios by segment are shown in the table below. The prior year adjustment in the table below reflects claims development and excludes premium adjustments.

									Accident Year Loss
									Ratio Excluding
	Total Loss			Prior Year			Hurricane Claims		Prior Year
For the Three Months Ended September 30, 2009	Ratio			Adjustment			Adjustment		Adjustments
Property reinsurance		25.9	%		12.0	%		—		37.9	%
Casualty reinsurance		63.0	%		8.3	%		—		71.3	%

Casualty reinsurance		67.2	%		8.6	%		—			75.8	%
International insurance		89.4	%		1.2	%		(25.1	)%		65.5	%

Total		95.2	%		3.6	%		(42.8	)%		56.0	%

Reserve releases.  The loss ratios take into account changes in our assessments of reserves for unpaid claims and loss adjustment expenses arising from earlier years. In the three months ended September 30, 2009 and 2008, we recorded a reduction in the level of reserves for prior years. The amounts of these reductions and their effect on the loss ratio in each period are shown in the following table:

34

	For the Three Months			For the Three Months
	Ended September 30, 2009			Ended September 30, 2008
Reserve releases ($ in millions)	$	44.2		$	15.6
% of net premiums earned		9.4	%		3.6	%

Reserve releases in the quarter increased by $28.6 million from the third quarter in 2008 due mainly to an increase in releases in the property reinsurance and the international insurance segments. Property reinsurance reserve releases increased by $15.8 million to $19.1 million due to better than expected development on outstanding claims particularly in our risk excess and property pro-rata lines of business. Our international insurance segment has also seen net reserve releases of $16.4 million as a result of favorable loss experience across most lines of business. These have been partially offset by reductions in reserve releases of $0.2 million in the casualty reinsurance segment and reserve strengthening in the U.S. insurance segment. The U.S. insurance segment strengthened prior year reserves by $0.8 million due to adverse experience from the casualty insurance business line compared to reserve releases of $0.7 million in the third quarter of 2008. Further information relating to the movement of prior year reserves can be found below under “Reserves for Loss and Loss Adjustment Expenses.”

Expense ratio.  We monitor the ratio of expenses to net earned premium (the “expense ratio”) as a measure of the cost effectiveness of our policy acquisition, operating and administrative processes. The table below presents the contribution of the policy acquisition expenses and operating and administrative expenses to the expense ratio and the total expense ratios for each of the three months ended September 30, 2009 and 2008:

	For the Three Months			For the Three Months
	Ended September 30, 2009			Ended September 30, 2008
Policy acquisition expenses		16.9	%		16.2	%
Operating and administrative expenses		13.5	%		11.9	%
Expense ratio		30.4	%		28.1	%

The policy acquisition expense ratio of 16.9% for the quarter has increased marginally from 16.2% in the third quarter of 2008, due mainly to an adjustment in acquisition expenses in casualty reinsurance and a change in the mix of business for U.S. insurance which has seen an increase in the proportion of property insurance business written that has higher average commission rates than casualty business.

The increase in the operating and administrative expense ratio to 13.5% from 11.9% in the third quarter of 2008 was driven predominantly byperformance-related remuneration linked to our improved performance during the period.

Net investment income.  In the third quarter of 2009, we generated net investment income of $58.9 million (2008 — $19.3 million). The increase in net investment income was due primarily to the comparative quarter in 2008 experiencing a loss of $42.2 million from our investment in funds of hedge funds. Investment income from fixed maturities decreased by $2.6 million compared to September 30, 2008 as a result of lower bond yields.

Change in fair value of derivatives.  In the three months ended September 30, 2009, we recorded a reduction of $2.0 million (2008 — $2.1 million reduction in the credit insurance contract less an adjustment of $1.4 million in changes in foreign exchange) in the estimated fair value of our credit insurance contract including an interest expense charge of $0.2 million (2008 — $0.2 million). Further information on these contracts can be found in Note 8 to the financial statements.

Other revenues and expenses.  Other revenues and expenses in the three months ended September 30, 2009 included $7.9 million of foreign currency exchange gains (2008 — $2.7 million loss) and $14.6 million of realized and unrealized investment gains (2008 — $58.1 million loss). Realized and unrealized gains included $8.7 million (2008 — $Nil) of unrealized gains and $1.3 million (2008 — $Nil) of net realized gains from our fixed income maturities trading portfolio for the three months ended September 30, 2009. The realized investment gains

35

in 2009 include a charge of $1.8 million for investments we believe to beother-than-temporarily impaired (2008 — $55.8 million).

Other-than-temporary impairments.  We review all of our investments in fixed maturities designated as available for sale for potential impairment each quarter based on criteria including issuer-specific circumstances, credit ratings actions and general macro-economic conditions. The process of determining whether a decline in value is“other-than-temporary” requires considerable judgment. As part of the assessment process we evaluate whether it is more likely than not that we will sell any fixed maturity security in an unrealized loss position before its market value recovers to amortized cost. Once a security has been identified asother-than-temporarily impaired, the amount of any impairment included in net income is determined by reference to the portion of the unrealized loss that is considered credit-related. Non-credit related unrealized losses are included in other comprehensive income.Other-than-temporary impairment losses of $1.8 million for the quarter are credit-related and therefore are included in the income statement. Theother-than-temporary impairment charge of $55.8 million in the third quarter of 2008 was attributable mainly to the write-down of Lehman Brothers bonds subsequent to that company’s collapse in September 2008.

Taxes.  The estimated effective rate of tax for the quarter is 14.8% (2008 — 13.6% credit). This is subject to revision in future periods if circumstances change and in particular, depending on the relative claims experience of those parts of business underwritten in Bermuda where the rate of tax on corporate profits is zero while the U.K. corporate tax rate is 28%.

Dividends.  The dividend has been maintained at $0.15 per ordinary share for the quarter.

Dividends paid on our preference shares in the three months ended September 30, 2009 were $5.6 million (2008 — $6.9 million). The reduction between the two periods is due to the repurchase and cancellation on March 31, 2009 of 2,672,500 of our 7.401% $25 liquidation preference shares.

Shareholders’ equity and financial leverage.  Total shareholders’ equity increased by $239.6 million to $3,212.1 million for the three months ended September 30, 2009. The most significant movements were:

•  net retained income after tax for the period of $127.6 million; and

•  unrealized appreciation on investments, net of taxes of $90.7 million.

As at September 30, 2009, total ordinary shareholders’ equity was $2,858.5 million compared to $2,359.9 million at December 31, 2008. The remainder of our total shareholders’ equity, as at September 30, 2009, was funded by two classes of preference shares with a total value as measured by their respective liquidation preferences of $353.6 million net of share issuance costs (December 31, 2008 — $419.2 million).

The amounts outstanding under our senior notes, less amortization of expenses, of $249.6 million (December 31, 2008 — $249.5 million) were the only material debt that we had outstanding as of September 30, 2009 and December 31, 2008.

Management monitors the ratio of debt to total capital, with total capital being defined as shareholders’ equity plus outstanding debt. At September 30, 2009, this ratio was 7.2% (December 31, 2008 — 8.2%).

Our preference shares are classified in our balance sheet as equity but may receive a different treatment in some cases under the capital adequacy assessments made by certain rating agencies. Such securities are often referred to as ‘hybrids’ as they have certain attributes of both debt and equity. We also monitor the ratio of the total of debt and hybrids to total capital which was 17.4% as of September 30, 2009 (December 31, 2008 — 22.1%).

36

Capital Management.  On March 31, 2009, we repurchased and cancelled 2,672,500 of our 7.401% $25 liquidation value preference shares (NYSE: AHL-PA) at a price of $12.50 per share. The purchase resulted in a gain attributable to ordinary shareholders of $31.5 million for the first quarter of 2009, which was not recognized in the income statement but was included in the calculation of earnings per share.

Liquidity.  Management monitors the liquidity of Aspen Holdings and of each of its Insurance Subsidiaries. With respect to Aspen Holdings, management monitors its ability to service debt, to finance dividend payments and to provide financial support to the Insurance Subsidiaries. As at September 30, 2009, Aspen Holdings held $8.9 million (2008 — $25.0 million) in cash and cash equivalents which, taken together with dividends declared or expected to be declared by subsidiary companies and our credit facilities, management considered sufficient to provide Aspen Holdings liquidity at such time.

At September 30, 2009, our subsidiaries held $939.9 million (2008 — $716.6 million) in cash and cash equivalents that are readily realizable securities. Management monitors the value, currency and duration of the cash and investments within its Insurance Subsidiaries to ensure that they are able to meet their insurance and other liabilities as they become due and was satisfied that there was a comfortable margin of liquidity as at September 30, 2009 and for the foreseeable future.

As of September 30, 2009, we had in issue $441.3 million and £18.8 million in letters of credit to cedants, for which the Company had funds on deposit of $588.7 million and £21.2 million as collateral for the secured letters of credit. Further information relating to letters of credit is found below under “Liquidity.”

Outlook and Trends

Property Reinsurance.  Within our property reinsurance segment, we had commented last quarter on the highly satisfactory pricing environment for U.S. catastrophe with pricing on average up 17% at the half year stage and the favorable impact this had on written premium. The proportional treaty and risk excess business lines have also performed well given challenging conditions where rates have increased between 3% and 5%.

Casualty Reinsurance.  The pricing conditions in the casualty reinsurance segment continue to be mixed with some rate increases in international business, with the U.S. closer to flat. Whereas in 2008 rate decreases were common, they are now less frequent with most business renewing on an “as before basis”. The international casualty line which represents approximately 30% of this segment is showing more positive trends. Specifically, we are experiencing more positive movement in professional lines and disciplined general liability pricing. We continue to believe that U.S. casualty rates across the market as a whole are inadequate and that pricing improvement is needed.

International Insurance.  In our international insurance segment as a whole, average rate increases are still in the double digits, although we continue to see significant variation by line of business. In energy and marine hull accounts, there has been some moderation from the high increases seen in previous quarters this year but average rates rises in these lines were 10% and 9%, respectively in the quarter. Significant price increases are also being achieved in the financial institutions account, particularly on larger clients. In aviation, the important October renewal season has completed and our current pricing confidence is well supported. For the quarter, we experienced average rate increases of 19% with increments of approximately 25% in airline business on average. Elsewhere in the segment, U.K. property rates are broadly flat within a range of +5% and −5%. Employers’ liability and public liability renewals in the U.K. are also tending to renew at close to expiring prices. In our U.K. professional liability line, conditions are still challenging but the rating trend is still upwards and we have achieved average rate increases in this line of 5%year-to-date.

U.S. Insurance.  In our U.S. insurance segment, the rating environment is unchanged from the second quarter. We continue to see some evidence of better pricing in catastrophe-exposed property risks but this is not the case in other property lines or casualty lines.

Application of Critical Accounting Policies

Our condensed consolidated financial statements are based on the selection of accounting policies and the application of significant accounting estimates, which require management to make significant estimates and assumptions. We believe that some of the more critical judgments in the areas of accounting estimates and assumptions that affect our financial condition and results of operations are related to reserves for property and liability losses, premiums receivable in respect of assumed reinsurance, the fair value of derivatives and the value of investments, including the extent of anyother-than-temporary impairment. For a detailed discussion of our critical accounting policies please refer to our 2008 Annual Report onForm 10-K filed with the United States Securities and Exchange Commission and the notes to the financial statements contained in this report.

We have discussed the application of these critical accounting estimates with our Board of Directors and Audit Committee.

Results of Operations for the Three Months Ended September 30, 2009 Compared to the Three Months Ended September 30, 2008

The following is a discussion and analysis of our consolidated results of operations for the three months ended September 30, 2009 and 2008 starting with a discussion of segmental results and then summarizing our consolidated results under “Total Income Statement — Third quarter” below.

Underwriting Results by Operating Segments

The Company is currently organized into four business segments: property reinsurance, casualty reinsurance, international insurance, and U.S. insurance. The Company has considered similarities in economic characteristics, products, customers, distribution, and the regulatory environment of the Company’s operating segments and quantitative thresholds to determine the Company’s reportable segments.

Management measures segment results on the basis of the combined ratio, which is obtained by dividing the sum of the losses and loss expenses, acquisition expenses and operating and administrative expenses by net premiums earned. Indirect operating and administrative expenses are allocated to segments based on each segment’s proportional share of gross earned premiums. As a relatively new company, our historical combined ratio may not be indicative of future underwriting performance. We do not manage our assets by segment; accordingly, investment income and total assets are not allocated to the individual segments. Please refer to the tables in Note 4 in our unaudited financial statements of this report for a summary of gross and net written and earned premiums, underwriting results and combined ratios and reserves for each of our four business segments for the three months ended September 30, 2009 and 2008.

The contributions of each segment to gross written premiums in the three months ended September 30, 2009 and 2008 were as follows:

	Gross Written Premiums
	For the Three Months			For the Three Months
Business Segment	Ended September 30, 2009			Ended September 30, 2008

Property Reinsurance

Our property reinsurance segment is mainly written on a treaty basis and includes catastrophe, risk excess, and proportional treaty risks. We also write U.S. and international property facultative risks. Our property reinsurance business is written out of Bermuda, London, the U.S., Paris, Zurich and Singapore. Aspen U.K.’s Paris branch writes property facultative business in continental Europe and the Zurich branch writes property and casualty reinsurance in Europe. We also write some structured risks out of Aspen Bermuda. We also include within this segment credit, surety and political risk reinsurance contracts written by the Zurich branch of Aspen U.K. This portfolio is written principally on a treaty basis.

Gross written premiums.  Gross written premiums in our property reinsurance segment increased by 12.0% compared to the three months ended September 30, 2008. This increase is attributed mainly to new premiums from the credit and surety line of business which began writing business in 2009 in addition to our geographic expansion into Singapore where we write property treaty and facultative business. The reduction in written premiums by our risk excess business line is due to a large contract which had previously been written on a combined risk excess and pro-rata basis which renewed on a pro-rata basis only.

The table below shows our gross written premiums for each line of business for the three months ended September 30, 2009 and 2008, and the percentage change in gross written premiums for each such line:

	Gross Written Premiums

Total	$	171.2		12.0	%	$	152.8

* Not meaningful — This line of business was not operational at September 30, 2008.

Losses and loss adjustment expenses.  The net loss ratio for the three months ended September 30, 2009 was 25.9% compared to 118.6% in 2008. An absence of significant catastrophe-related losses in the quarter compared to losses from Hurricanes Ike and Gustav in the third quarter of 2008 is the main driver for the reduction in the net loss ratio. Reserve releases in the quarter were $19.1 million, up from $3.3 million in the third quarter of 2008 with the increase driven by better than expected development on outstanding claims, particularly in our risk excess and property pro-rata lines.

Further information relating to the movement of prior year reserves is found below under “Reserves for Losses and Loss Adjustment Expenses.”

Policy acquisition, operating and administrative expenses.  Total expenses were $45.4 million equivalent to 32.2% of net premiums earned for the three months ended September 30, 2009 compared with $38.1 million or 27.4% of net premiums earned for the three months ended September 30, 2008. The increase in the expense ratio is driven by the higher operating and administrative expense ratio which increased to 14.9% from 10.6% in the third quarter of 2008. The increase in operating and administrative expenses of $6.3 million from the third quarter of 2008 is attributable mainly to an increase in performance-related expenses.

Casualty Reinsurance

Our casualty reinsurance segment is written mainly on a pro rata and treaty basis with a small proportion of facultative risks. Casualty treaty reinsurance is primarily written on an excess of loss basis and includes coverage for claims arising from automobile accidents, employers’ liability, professional indemnity and other third party liabilities. It is written in respect of cedants located mainly in the United States, the United Kingdom, Europe and Australia. We also write some structured reinsurance contracts out of Aspen Bermuda.

Gross written premiums.  Gross written premium increased by 21.1% to $96.5 million due mainly to additional premiums of $13.0 million for the 2006 and 2007 years in our U.S. casualty treaty line. The table below shows our gross written premiums for each line of business for the three months ended September 30, 2009 and 2008, and the percentage change in gross written premiums for each such line:

	Gross Written Premiums
	For the Three Months					For the Three Months

Casualty facultative		5.4		25.6			4.3
Total	$	96.5		21.1	%	$	79.7

Losses and loss adjustment expenses.  Losses and loss adjustment expenses for the third quarter of 2009 decreased by $3.3 million when compared to the third quarter of 2008. The decrease is attributable mainly to the third quarter of 2008 including a $10 million increase in loss provisions for potential exposure associated with the global financial crisis. Prior year reserve releases are further discussed below under “Reserves for Losses and Loss Expenses.”

Policy acquisition, operating and administrative expenses.  Total expenses were $29.1 million for the three months ended September 30, 2009 equivalent to 25.3% of net premiums earned (2008 — 23.2%). Policy acquisition expenses have increased by $2.6 million in the third quarter of 2009 compared to the same period in 2008, as the comparative period included an adjustment to brokerage in the international treaty business line. Operating and administrative expenses of $9.9 million are broadly in line with the same period in 2008.

International Insurance

Our international insurance segment comprises marine hull, marine, energy and construction liability, energy property damage, aviation, professional liability, excess casualty, financial institutions, financial and political risk, specie, management and technology liability, U.K. commercial property (including construction) and U.K. commercial liability insurance. The U.K. commercial liability line of business consists of U.K. employers’ and public liability insurance. Our specialty reinsurance lines of business include aviation, marine and other specialty reinsurance.

Gross written premiums.  Overall premiums have increased marginally to $183.9 for the quarter from $180.8 million in the equivalent period in 2008. The increase in gross written premium is attributable to a $4.7 million contribution from the specie and management and technology liability business lines which commenced underwriting after the third quarter of 2008, compensating for a small net reduction in premiums written in the other business lines. We have written 26% less premium in energy property insurance than the comparable period of 2008 due to a lack of demand for wind cover and we have written 50% less premium in financial institutions due to the repositioning of the business line following the global financial crisis.

41

Gross written premiums in our U.K. commercial property and liability lines have also been adversely impacted by exchange rate movements as premiums are written in British Pounds which has weakened against the U.S. Dollar during the period.

The table below shows our gross written premiums for each line of business for the three months ended September 30, 2009 and 2008, and the percentage change in gross written premiums for each line:

Losses and loss adjustment expenses.  The loss ratio for the quarter was 60.3% compared to 89.4% for the three months ended September 30, 2008, a decrease of 29.1 percentage points. During the third quarter of 2008, the segment was impacted by Hurricanes Ike and Gustav which increased the loss ratio by 25.1 percentage points during that quarter. The three months ended September 30, 2009 were not impacted by any such catastrophic events with the only notable net loss being $7.0 million following a failed satellite launch. Prior year reserve releases have increased by $14.5 million to $16.4 million due to generally favorable loss experience across a number of lines of business.

Policy acquisition, operating and administrative expenses.  Policy acquisition expenses were $31.0 million for the three months ended September 30, 2009 equivalent to 16.5% of net premiums earned (2008 — $26.5 million or 16.7% of net earned premium). The increase in operating and administrative expenses to $24.5 million in the third quarter of 2009 from $21.1 million for the comparative period in 2008 is attributable mainly to an increase in profit-related staff costs. The additional costs have been partly offset by favorable movements in the exchange rates between the U.S. Dollar and the British Pound.

U.S. Insurance

We write both U.S. property and casualty insurance on an excess and surplus lines basis. We also write property insurance that provides underwriting support to a select group of U.S. program managers. This is referred to as our risk solutions business.

Gross written premiums.  Gross written premiums increased by 38.2% compared to the third quarter of 2008 due mainly to new business subsequent to the reshaping of our property insurance line in 2008 and increased prices for catastrophe-exposed business. Casualty premium is broadly in line with the prior period while an additional $2.5 million contribution was recognized in the new risk solutions line of business.

The table below shows our gross written premiums for each line of business for the three months ended September 30, 2009 and 2008, and the percentage change in gross written premiums for each such line:

	Gross Written Premiums
	For the Three Months					For the Three Months

Total	$	38.7		38.2	%	$	28.0

* Not meaningful — This line of business was not operational at September 30, 2008.

Losses and loss adjustment expenses.  The loss ratio has decreased from 130.1% for the third quarter of 2008 to 47.4% for the same period in 2009 mainly as a result of the prior period experiencing $15.0 million of losses related to Hurricanes Ike and Gustav. In the third quarter of 2008, there were reserve releases of $0.7 million compared to $0.8 million of reserve strengthening in the third quarter of 2009 due to a small deterioration in casualty insurance which exhibited marginally worse than expected experience.

Policy acquisition, operating and administrative expenses.  Policy acquisition expenses have increased to $5.0 million in the current period from $3.9 million for the equivalent period in 2008 due mainly to higher earned premium and changes in the business mix.

Operating and administrative expenses have increased to $8.3 million in 2009 from $6.2 million in 2008 due mainly to an increase related to certain reorganization costs.

Total Income Statement — Third quarter

Our statements of operations consolidates the underwriting results of our four segments and includes certain other revenue and expense items that are not allocated to the business segments.

Gross written premiums.  Gross written premiums for the third quarter of 2009 have increased by 11.1% to $490.3 million when compared to the third quarter of 2008 due mainly to increased contributions from our property reinsurance and casualty reinsurance segments. The casualty reinsurance segment has benefited principally from $13.0 million of premium adjustments, particularly in our U.S. treaty business. The property reinsurance segment has benefited from a $27.3 million contribution from the newly established credit, surety and political risk business line compensating for reductions in premiums written in our treaty risk excess business line. Our U.S. insurance segment has also experienced growth in the quarter particularly in the property line due mainly to new business subsequent

43

to the reshaping of the portfolio in 2008 and increased prices for catastrophe exposed business. Gross written premiums in the international insurance segment have increased marginally by 1.7% to $183.9 million when compared to the third quarter of 2008 due to a $4.7 million contribution from the specie and management and technology liability business lines which commenced underwriting after the third quarter of 2008, compensating for a small net reduction in premiums written in the other business lines.

Reinsurance ceded.  Total reinsurance ceded for the three months ended September 30, 2009 of $28.2 million decreased by $9.3 million from the third quarter of 2008. The reduction in ceded written premiums in the quarter is due to the comparative period including $7.4 million of reinstatement premiums associated with Hurricanes Ike and Gustav.

Gross premiums earned.  Gross premiums earned reflect the portion of gross premiums written which are recorded as revenues over the policy periods of the risks we write. The earned premium recorded in any year includes premium from policies incepting in prior years and excludes premium to be earned subsequent to the reporting date. Gross premiums earned in the third quarter of 2009 increased by 8.1% compared to the third quarter of 2008 reflecting the earning of the newer business lines written in the second half of 2008.

Net premiums earned.  Net premiums earned have increased by $36.7 million or 8.5% in the third quarter of 2009 compared to 2008 which is consistent with the increase in gross earned premiums. The increase in gross earned premiums has been partially offset by an increase in ceded earned premiums resulting from the increases in reinsurance purchased to cover new lines.

Losses and loss adjustment expenses.  The decrease in losses and loss adjustment expenses resulted from the prior year experiencing $186.0 million of losses from Hurricanes Ike and Gustav. Reserve releases are higher in the current quarter due generally to favorable development across most lines.

The underlying changes in accident year loss ratios by segment are shown in the table below. The prior year adjustment in the table below reflects claims development and excludes premium adjustments.

Expenses.  We monitor the ratio of expenses to gross earned premium (the “gross expense ratio”) as a measure of the cost effectiveness of our policy acquisition, operating and administrative processes. The table below presents the contribution of the policy acquisition expenses and operating and administrative expenses to the expense ratio and the total expense ratios for the three months ended September 30, 2009 and 2008. We also show the effect of reinsurance which impacts on the reported net expense ratio by expressing the expenses as a proportion of net earned premiums.

Changes in the acquisition and operating and administrative ratios to gross earned premiums and the impact of reinsurance on net earned premiums by segment for each of the three months ended September 30, 2009 and 2008 are shown in the following table:

	For the Three Months Ended September 30, 2009															For the Three Months Ended September 30, 2008

The policy acquisition ratio, gross of the effect of reinsurance, has increased to 15.2% for the three months ended September 30, 2009 from 14.6% for the comparative period in 2008. The third quarter of 2008 had an adjustment to brokerage in the casualty reinsurance segment which contributed to a lower expense figure in that period. The increase was also due to changes in business mix in the U.S. insurance and international insurance segments which changed the relative contributions from business lines which have different average acquisition costs.

Between the two periods we have experienced a $12.1 million increase in our operating and administrative expenses. The increase is due mainly to profit related staff costs but also to $1.8 million of expenses associated with the new teams.

Net investment income.  Net investment income consists of interest on fixed income securities, short term investments and money market holdings, and the change in value of other investments, less investment management fees. In the third quarter of 2009, we generated net investment income of $58.9 million (2008 — $19.3 million). The $39.6 million increase in investment income was primarily due to the 2008 period having losses of $42.2 million from our investment in funds of hedge funds reported in investment income in the three months ended September 30, 2008. Book yield on our fixed income portfolio of 4.4% is broadly in line with the second quarter of 2009, however, it has decreased from 4.9% in the third quarter of 2008 due mainly to the decrease in interest rates. The portfolio duration increased from 3.2 years at the end of the second quarter of 2009 to 3.3 years. This compares with 3.5 years in the third quarter of 2008. The average credit quality of our fixed income portfolio is “AA+”, with 73% (2008 — 88%) of the portfolio being rated “AA” or higher.

Change in fair value of derivatives.  In the three months ended September 30, 2009, we recorded a reduction of $2.0 million (2008 — $0.7 million) in the estimated fair value of our credit insurance contract including $0.2 million (2008 — $0.3 million) of interest expense. Further information on these contracts can be found in Note 8 to the financial statements.

Other-than-temporary impairments.  We review all of our fixed maturities for potential impairment each quarter based on criteria including issuer-specific circumstances, credit ratings actions and general macro-economic conditions. The process of determining whether a decline in value is “other-than-temporary” requires considerable judgment. As part of the assessment process we also evaluate whether it is more likely than not that we will sell any fixed maturity security in an unrealized loss position before its market value recovers to amortized cost. Once a security has been identified as other-than-temporarily impaired, the amount of any impairment included in net income is determined by reference to the portion of the unrealized loss that is considered credit-related. Non-credit related unrealized losses are included in other comprehensive income. The realized investments losses in the third quarter of 2009 include a $1.8 million charge for investments we believe to be other-than-temporarily impaired (2008 — $55.8 million). Other-than-temporary impairment losses of $1.8 million for the quarter were credit related and therefore are included in the income statement. The other-than-temporary impairment charge of

46

$55.8 million in the third quarter of 2008 was attributable mainly to the write-down of Lehman Brothers bonds subsequent to that company’s collapse in September 2008.

Income before tax.  In the third quarter of 2009, income before tax was $171.1 million and comprised $92.5 million of underwriting profit, $58.9 million in net investment income, $22.5 million of net realized and unrealized investment and foreign exchange gains $3.9 million of interest expense and $1.1 million of other income. In the third quarter of 2008, we reported a loss before tax of $145.9 million which comprised $101.2 million of underwriting loss, $19.3 million in net investment income, $60.8 million of net foreign exchange and investment losses, $0.6 million of other income and $3.8 million of interest expense. Underwriting losses in the third quarter of 2008 were heavily impacted by Hurricanes Ike and Gustav. Our higher net investment income in the quarter was due to the absence of losses from our investments funds of hedge funds which we redeemed with effect on June 30, 2009.

Income tax expense.  Income tax expense for the three months ended September 30, 2009 was $25.3 million. Our effective consolidated tax rate for the three months ended September 30, 2009 was 14.8% (2008 — 13.6% credit). The charge represents an estimate of the tax rate which will apply to our pre-tax income for 2009. As discussed in the “Overview” above, the effective tax rate may be subject to revision.

Net income after tax.  Net income after tax for the three months ended September 30, 2009 was $145.8 million, equivalent to $1.69 basic earnings per ordinary share adjusted for the $5.6 million preference share dividends and $1.63 fully diluted earnings per ordinary share adjusted for the preference share dividends on the basis of the weighted average number of ordinary shares in issue during the three months ended September 30, 2009. The net loss for the three months ended September 30, 2008 was $126.1 million equivalent to a basic and diluted loss of $1.63 per ordinary share.

Results of Operations for the Nine Months Ended September 30, 2009 Compared to the Nine Months Ended September 30, 2008

The following is a discussion and analysis of our consolidated results of operations for the nine months ended September 30, 2009 and 2008 starting with a discussion of segmental results and then summarizing our consolidated results under “Total Income Statement — Nine months ended September 30, 2009” below.

Underwriting Results by Operating Segments

Property Reinsurance

For a description of our property reinsurance segment, refer to “Results of Operations for the Three Months Ended September 30, 2009 Compared to the Three Months Ended September 30, 2008 — Property Reinsurance,” above.

Gross written premiums.  Gross written premiums in our property reinsurance segment increased by 12.7% compared to the nine months ended September 30, 2008. This increase is mainly due to the $42.9 million contribution from our new credit, surety and political risk team.

The table below shows our gross written premiums for each line of business for the nine months ended September 30, 2009 and 2008, and the percentage change in gross written premiums for each such line:

Losses and loss adjustment expenses.  The net loss ratio for the nine months ended September 30, 2009 was 23.6% compared to 61.9% in 2008 due to a lack of hurricane losses in 2009 and a $27.1 million increase in prior year reserve releases compared to the prior period. The loss ratio in 2008 was adversely affected by $131.2 million of losses from Hurricanes Ike and Gustav and a high incidence of risk losses particularly in the first quarter of 2008. Reserve releases in the year to date were $46.6 million, up from $19.5 million in the nine months ending September 30, 2008 due mainly to favorable loss experience in relation to reductions in loss provisions for 2008 hurricane losses and better than expected development on outstanding claims. Further information relating to the movement of prior year reserves is found below under “Reserves for Losses and Loss Adjustment Expenses.”

Policy acquisition, operating and administrative expenses.  Total expenses were $128.4 million for the nine months ended September 30, 2009 equivalent to 31.2% of net premiums earned (2008 — 31.5%). The policy acquisition expense ratio for the nine months ended September 30, 2009 of 18.7% is in line with 2008. The increase in the operating and administrative expenses to $51.3 million from $49.7 million for the comparative period in 2008 is mainly attributable to profit related staff costs partly offset by continued cost management and favorable movement in the exchange rate between the U.S. Dollar and British Pounds between the two periods.

Casualty Reinsurance

For a description of our casualty reinsurance segment, refer to “Results of Operations for the Three Months Ended September 30, 2009 Compared to the Three Months Ended September 30, 2008 — Casualty Reinsurance.”

Gross written premiums.  The 7.4% increase in gross written premiums for the segment was due mainly to an increased contribution from our U.S. treaty business unit which has recorded additional premiums from adjustable contracts. The reduction in premiums from the international treaty business line was due to increased competition. The table below shows our gross written premiums for each line of business for the nine months ended September 30, 2009 and 2008, and the percentage change in gross written premiums for each such line:

	Gross Written Premiums
	For the Nine Months					For the Nine Months
Lines of Business	Ended September 30, 2009					Ended September 30, 2008
	($ in millions)		% increase/			($ in millions)

U.S. treaty	$	237.8		21.0	%	$	196.6
International treaty		92.8		(16.0	)		110.5
Casualty facultative		11.7		1.7			11.5
Total	$	342.3		7.4	%	$	318.6

Losses and loss adjustment expenses.  Losses and loss adjustment expenses increased by $22.1 million in 2009 compared to the equivalent period in 2008, due primarily to a $29.4 million decrease in prior year reserve releases. The change in reserve releases is mainly due to the international casualty treaty line which experienced a reserve strengthening of $5.6 million in the period compared to a $22.6 million release in the nine months ended September 30, 2008. The reserve strengthening for international casualty was due to adverse development on our auto and general liability accounts. Prior year reserve movements are further discussed below under “Reserves for Losses and Loss Expenses.”

Policy acquisition, operating and administrative expenses.  Total expenses were $91.1 million for the nine months ended September 30, 2009 equivalent to 27.9% of net premiums earned (2008 — 26.9%). The policy acquisition expense ratio has increased to 18.7% in 2009 from 15.7% in 2008 driven mainly by a $2.0 million increase in profit commission accruals but also due to 2008 including an adjustment to brokerage which resulted in a lower expense. This has been offset by a decrease in the operating and administrative expense ratio from 11.2% in 2008 to 9.2% in the current year due to a $3.0 million reallocation of expenses to property reinsurance, and favorable movement in the exchange rate between the U.S. Dollar and British Pound between the two periods.

For a description of our international insurance segment, refer to “Results of Operations for the Three Months Ended September 30, 2009 Compared to the Three Months Ended September 30, 2008 — International Insurance.”

Gross written premiums.  Overall premiums have reduced by $21.7 million in the period compared to the nine months ended September 30, 2008, mainly due to our response to market conditions in certain lines of business and adverse exchange rate movements impacting our U.K. property and liability business lines. The contribution from our professional liability and excess casualty business lines has increased as these new lines were still being established in the first half of 2008. Marine, energy and construction liability has also benefited from additional premiums from loss affected contracts in 2008. Even though rates for Gulf of Mexico energy risks have improved significantly, some clients chose to buy less insurance or retain the risk altogether. Our premiums written in financial institutions have also decreased due to the repositioning of this line following the global financial crisis. We also declined a number of risks that did not meet our underwriting criteria.

Losses and loss adjustment expenses.  The net loss ratio for the nine months ended September 30, 2009 was 67.1% compared to 68.5% in 2008. The improvement in the loss ratio in the period is due mainly to $39.8 million of losses from Hurricanes Ike and Gustav in 2008. The reduction in reserve releases from $20.0 million in 2008 to $12.7 million in 2009 is predominately due to increased provisions for those lines affected by the global financial crisis and to adverse development on our marine, energy and construction liability and non-marine and transportation liability (which now forms part of excess casualty) business lines. Current year losses have been impacted by our aviation and specialty reinsurance lines which have suffered from a $10.6 million net loss associated with the Air France disaster and a $7.0 million satellite loss. In the first half of 2008, the segment suffered from a $6.4 million satellite loss, a $15.9 million pollution loss in France and a $3.4 million airline loss. Prior year reserve releases are further discussed under “Reserves for Losses and Loss Expenses.”

Policy acquisition, operating and administrative expenses.  Total expenses were $154.8 million for the nine months ended September 30, 2009 equivalent to 29.1% of net premiums earned (2008 — 29.4%). The acquisition expense ratio has reduced by 0.4 percentage points in the period due to changes in the relative contributions from the business lines.

Operating and administrative expenses have increased by $7.7 million compared to the nine months ended September 30, 2008 mainly due to the recognition of profit-related staff costs, increases in personnel costs associated with the establishment of our new underwriting teams and costs associated with the Lloyd’s syndicate.

U.S. Insurance

We write both U.S. property and casualty insurance on an excess and surplus lines basis. We also write property insurance that provides underwriting support to a select group of U.S. program managers. We refer to this as our risk solutions business.

Gross written premiums.  Gross written premiums increased by 28.6% compared to the prior period of 2008. The written premium increase is the result of new business written as the property account has been reshaped, increased prices for catastrophe exposed business and the program property business written by the new risk solutions team.

The table below shows our gross written premiums for each line of business for the nine months ended September 30, 2009 and 2008, and the percentage change in gross written premiums for each such line:

	Gross Written Premiums

* Not Meaningful — This line of business was not operational at September 30, 2008.

Losses and loss adjustment expenses.  Losses for the period have decreased by $1.1 million. Even though the period in 2008 experienced losses of $15.0 million from Hurricanes Ike and Gustav, the period benefitted from $8.1 million of reserve releases. In contrast, the nine-month period in 2009 experienced reserve strengthening of $6.9 million. This strengthening is attributable to adverse loss development on our casualty line where incurred development has been greater than expected.

Policy acquisition, operating and administrative expenses.  Policy acquisition expenses have decreased by $0.5 million due to changes in the mix of property business. Operating and administrative expenses have increased from $18.8 million in 2008 to $24.9 million in 2009 due primarily to reorganization costs. The expense ratio continues to be adversely impacted in the short-term as a result of the investment we have made to rebuild the account and reshape our U.S. operations.

Total Income Statement — Nine Months ended September 30, 2009

Our statements of operations consolidates the underwriting results of our four segments and includes certain other revenue and expense items that are not allocated to the business segments.

Gross written premiums.  Gross written premiums increased in the first nine months of 2009 by 6.1% compared to the corresponding period in 2008 as a result of a number of factors including the $42.9 million contribution from our new credit, surety and political risk team included in the property reinsurance segment, an increased contribution from our U.S. casualty treaty business unit which has recorded additional premiums from adjustable contracts and new U.S. insurance business written as the property account has been reshaped, increased prices for catastrophe-exposed business and the program property business written by the new risk solutions team.

Reinsurance ceded.  Our reinsurance spend of $208.0 million is 51.9% higher than the corresponding period of 2008, because in 2007 we had taken the opportunity to purchase property covers at favorable prices for two wind seasons. We have experienced a general increase in price for reinsurance in 2009, an increase due to the purchase of reinsurance for our newer lines and due to reinstatement costs following losses in our financial institutions and aviation insurance business lines.

51

Gross premiums earned.  Gross premiums earned in the first nine months of 2009 increased by 11.6% compared to 2008 primarily from the new lines of business which have now earned premium through a full year and also as a result of the favorable market conditions particularly in property reinsurance and U.S. property insurance.

Net premiums earned.  Net premiums earned have increased by 10.1% in the first nine months of 2009 compared to the first nine months of 2008 due to additional premiums from our new lines of business being partially offset by additional reinsurance costs.

Losses and loss adjustment expenses.  The loss ratio decreased from 66.1% in the nine months period of 2008 to 53.5% in the nine months ended September 30, 2009. Excluding the impact of Hurricanes Ike and Gustav, the loss ratio has increased in 2009 by 2.6 percentage points predominantly as a result of a reduction in prior year reserve releases by $24.6 million. Further information relating to movements in prior year reserves can be found below under “Reserves for Loss and Loss Adjustment Expenses.”

The underlying changes in loss ratios by segment are shown in the table below. The prior year adjustment in the table below reflects claims development and does not reflect the impact of prior year premium adjustments.

Expenses.  We monitor the ratio of expenses to gross earned premium (the “gross expense ratio”) as a measure of the cost effectiveness of our policy acquisition, operating and administrative processes. The table below presents the contribution of the policy acquisition expenses and operating and administrative expenses to the expense ratio and the total expense ratios for the nine months ended September 30, 2009 and 2008.

We also show the effect of reinsurance which impacts on the reported net expense ratio by expressing the expenses as a proportion of net earned premiums. Changes in the acquisition and operating and administrative ratios to gross earned premiums and the impact of reinsurance on net earned premiums by segment for each of the nine months ended September 30, 2009 and 2008 are shown in the following table (ratios shown as percentages):

The policy acquisition ratio, gross of the effect of reinsurance, has increased marginally to 15.9% for the nine months ended September 30, 2009 from 15.7% for the comparative period in 2008. The operating and administrative expense ratio has improved to 11.4% in 2009 from 11.8% in 2008 driven by increased earned premium, cost management initiatives and favorable movements in the exchange rate between the U.S. dollar and British Pound between the two periods.

Net investment income.  Net investment income consists of interest on fixed income securities, short term investments and money market holdings, and the change in value of other investments, less investment management fees. In the first nine months of 2009, we generated net investment income of $190.3 million (2008 — $128.9 million). The $61.4 million increase in investment income was primarily due to $20.2 million of gains from our investment in funds of hedge funds compared to $48.3 million of losses in the comparable period of 2008. The contribution from fixed income investments and cash has reduced by $7.1 million as during the period, the book yield on our fixed income portfolio has decreased from 4.9% to 4.4%. During the same period, the fixed income portfolio duration has decreased from 3.5 years to 3.3 years.

Change in fair value of derivatives.  In the nine months ended September 30, 2009, we recorded a reduction of $5.8 million (2008 — $3.8 million credit insurance contract; $1.4 million foreign exchange contract) in the estimated fair value of our credit insurance contract including $0.4 million (2008 — $0.6 million) of interest expense. In the third quarter of 2009, we held foreign currency derivative contracts to purchase $18.8 million of foreign currencies. The foreign currency contracts are recorded as derivatives at fair value with the gain or loss recorded in net foreign exchange gains and losses. For the nine months ended September 30, 2009, the impact of foreign currency contracts on net income was a charge of $1.8 million (2008 — $3.8 million). Further information on these contracts can be found in Notes 7 and 8 to the financial statements.

Other-than-temporary impairments.  We review all of our fixed maturities for potential impairment each quarter based on criteria including issuer-specific circumstances, credit ratings actions and general macro-economic conditions. The process of determining whether a decline in value is “other-than-temporary” requires considerable judgment. As part of the assessment process we also evaluate whether it is more likely than not that we will sell any fixed maturity security in an unrealized loss position before its market value recovers to amortized cost. Once a security has been identified as other-than-temporarily impaired, the amount of any impairment included in net income is determined by reference to the portion of the unrealized loss that is considered credit-related. Non-credit related unrealized losses are included in other comprehensive income. The realized investments losses in the nine months ended September 30, 2009 include a $19.9 million charge for investments we believe to be other-than-temporarily impaired (2008— $55.8 million). Other-than-temporary impairment losses of $19.9 million for the nine-month period are credit related and therefore are included in the income statement. The other-than-temporary

53

impairment charge of $55.8 million in the third quarter of 2008 was attributable mainly to the write-down of Lehman Brothers bonds subsequent to that company’s collapse in September 2008.

Income before tax.  In the first nine months of 2009, income before tax was $408.6 million and comprised $215.1 million of underwriting profit, $190.3 million in net investment income, $15.9 million of net foreign exchange and investment gains, $11.8 million of interest expense and $0.9 million of other expenses. In the first nine months of 2008, income before tax was $98.8 million and comprised $42.9 million of underwriting profit, $128.9 million in net investment income, $59.7 million of net foreign exchange and investment losses, $11.7 million of interest expense and $1.6 million of other expenses. The higher underwriting profit in the first nine months of 2009 was due primarily to the lack of catastrophes in the period which was partly offset by a $24.6 million reduction in prior year reserve releases. Our higher investment income in the first nine months of 2009 compared to the prior period was due to a positive contribution from our fund of hedge fund investments, compared to a loss from the fund of hedge funds in the prior period.

Income tax expense.  Income tax expense for the nine months ended September 30, 2009 was $61.0 million. Our consolidated tax rate for the nine months ended September 30, 2009 was 15.0% (2008 — 17.0%). The charge represents an estimate of the tax rate which will apply to our pre-tax income for 2009. As discussed in the “Overview” above, the effective tax rate may be subject to revision.

Net income after tax.  Net income after tax for the nine months ended September 30, 2009 was $347.6 million, equivalent to $4.37 basic earnings per ordinary share adjusted for the $18.3 million preference share dividends and $4.25 fully diluted earnings per ordinary share adjusted for the preference share dividends on the basis of the weighted average number of ordinary shares in issue during the nine months ended September 30, 2009. The net income for the nine months ended September 30, 2008 was $82.0 million equivalent to basic earnings of $0.73 per ordinary share and fully diluted earnings of $0.71 per share.

Reserves for Losses and Loss Expenses

As of September 30, 2009, we had total net loss and loss adjustment expense reserves of $2,980.5 million (December 31, 2008 — $2,787.0 million). This amount represented our best estimate of the ultimate liability for payment of losses and loss adjustment expenses. Of the total gross reserves for unpaid losses of $3,314.0 million at the balance sheet date of September 30, 2009, a total of $1,999.4 million or 60.0% represented IBNR claims (December 31, 2008 — $3,070.3 million and 58.3%, respectively). The following tables analyze gross and net loss and loss adjustment expense reserves by segment.

(1) The 2008 net reserve position for each of our segments has been revised with no overall effect on the total. As a result of a re-allocation of reinsurance recoverables among the segments, the net reserve position for property reinsurance increased by $69.9 million from $380.7 million to $450.6 million, for casualty reinsurance decreased by $3.6 million from $1,308.8 million to $1,305.2 million, for international insurance decreased by $97.2 million from $1,003.7 million to $906.5 million and for U.S. insurance increased by $30.9 million from $93.8 million to $124.7 million.

The increase in reinsurance recoverables in 2009 is due to increased recoveries in our international insurance segment related mainly to losses from Hurricane Ike, the Air France disaster and the global financial crisis. This has been offset by the continued settlement of losses associated with Hurricanes Katrina, Rita and Wilma.

For the nine months ended September 30, 2009, there was a reduction of our estimate of the ultimate net claims to be paid in respect of prior accident years of $71.0 million. An analysis of this reduction by line of business is as follows for each of the three and nine months ended September 30, 2009 and 2008:

	For the Three Months Ended					For the Nine Months Ended
Business Segment	September 30, 2009			September 30, 2008		September 30, 2009			September 30, 2008
	($ in millions)					($ in millions)
Property reinsurance	$	19.1		$	3.3	$	46.6		$	19.5
Casualty reinsurance		9.5			9.7		18.6			48.0
International insurance		16.4			1.9		12.7			20.0
U.S. insurance		(0.8	)		0.7		(6.9	)		8.1
Total Losses and loss expense reserves reductions	$	44.2		$	15.6	$	71.0		$	95.6

The key elements which gave rise to the net favorable development during the three months ended September 30, 2009 were as follows:

Property Reinsurance:  The reserve release in the current quarter is a result of better than expected incurred development on all classes in the segment, including settlement of Hurricane Ike and Gustav claims, spread across several accident years.

Casualty Reinsurance:  The release in the quarter is largely driven by the U.S. casualty lines ($9.5 million) which continue to exhibit favorable development across the 2003 — 2006 accident years.

International Insurance:  All areas in the segment were either flat or showed reserve releases. The most significant of these were releases of $6.6 million in U.K. liability, $2.4 million in aviation, $4.7 million in specialty reinsurance, and $1.2 million in U.K. property, with the balance of $1.5 million spread through several other lines.

U.S. Insurance:The small deterioration this quarter is from casualty insurance which exhibited marginally worse than expected experience.

We did not make any significant changes in assumptions used in our reserving process. However, because the period of time we have been in operation is relatively short, for longer tail lines in particular, our loss experience is limited and reliable evidence of changes in trends of numbers of claims incurred, average settlement amounts, numbers of claims outstanding and average losses per claim will necessarily take years to develop.

For a more detailed description see “Management’s Discussion and Analysis — Critical Accounting Policies” and “Management’s Discussion and Analysis — Reserves for Losses and Loss Adjustment Expenses,” included in our 2008 Annual Report onForm 10-K filed with the United States Securities and Exchange Commission.

Investment funds.  Investment funds represented our investments in funds of hedge funds which were recorded using the equity method of accounting. Adjustments to the carrying value of these investments were made based on the net asset values reported by the fund managers, resulting in a carrying value that approximates fair value. Realized and unrealized gains or losses of $nil (2008 — loss of $42.2 million) and $20.2 million (2008 — loss of $48.3 million) have been recognized through the statement of operations in the three and nine months ended September 30, 2009, respectively. We invested $150.0 million in the share capital of two funds in 2006, a further $247.5 million in one of these funds and $112.5 million in the share capital of a third fund in 2007. In 2008, we sold share capital in the funds that cost $198.6 million for proceeds of $177.2 million realizing a loss of $21.4 million. In February 2009, we gave notice to redeem the balance of the funds with effect on June 30, 2009. As a result, we recognized proceeds from the redemption of funds of $307.1 million at June 30, 2009.

Our involvement with the funds ceased at June 30, 2009. The carrying value of the receivables represents our maximum exposure to loss at the balance sheet date of the $16.3 million receivable at September 30, 2009, $4.8 million was received by October 31, 2009 with the remaining balance of $11.5 million to be received subsequent to the completion of the audited financial statements for the funds.

Cartesian Iris 2009A L.P.  On May 19, 2009, we invested $25 million with Cartesian Iris 2009A L.P. through our wholly owned subsidiary, Acorn Limited. Cartesian Iris 2009A L.P. is a Delaware Limited Partnership formed to provide capital to Iris Re, a newly formed Class 3 Bermuda reinsurer focusing on insurance linked securities. In addition to returns on our investment, we will receive a fee for providing advice on risk selection, pricing and portfolio design. In the three and nine months ended September 30, 2009, a fee of $0.1 million was payable to Aspen.

Valuation of Investments

Valuation of Fixed Income and Short Term Available for Sale Investments and Fixed Income and Short Term Trading Investments.  All of the fixed income securities are traded on the over the counter market, based on prices provided by one or more market makers in each security. In addition, there are readily observable market value indicators. We use a variety of pricing sources to value our fixed income securities including those securities that have prepayment features such as mortgage-backed securities and asset-backed securities in order to ensure fair and accurate pricing. The fair value estimates of the securities in our portfolio are not sensitive to significant unobservable inputs or modeling techniques.

57

Valuation of Other Investments.  The value of our investments in funds of hedge funds were based upon monthly net asset values using fair value reported by the underlying funds to our funds of hedge funds managers. The financial statements of our funds of hedge funds were subject to annual audits evaluating the net asset positions of the underlying investments. We periodically reviewed the performance of our funds of hedge funds and evaluated the reasonableness of the valuations.

The value of our investment in Cartesian Iris 2009A L.P. is based on our shares of the capital position of the partnership which includes income and expenses reported by the limited partnership as provided in its quarterly management accounts. Cartesian Iris 2009A L.P. is subject to annual audit evaluating the financial statements of the partnership. We periodically review the management accounts of Cartesian Iris 2009A L.P. and evaluate the reasonableness of the valuation of our investment.

Other-than-temporary impairment.  We review all of our fixed maturities for potential impairment each quarter based on criteria including issuer-specific circumstances, credit ratings actions and general macro-economic conditions. The process of determining whether a decline in value is“other-than-temporary” requires considerable judgment. As part of the assessment process we also evaluate whether it is more likely than not that we will sell any fixed maturity security in an unrealized loss position before its market value recovers to amortized cost. Once a security has been identified asother-than-temporarily impaired, the amount of any impairment included in net income is determined by reference to that portion of the unrealized loss that is considered to be credit related. Non-credit related unrealized losses are included in other comprehensive income.Other-than-temporary impairment is discussed further in Notes 2 and 5 of the unaudited condensed consolidated financial statements.

Capital Management

On March 31, 2009, we repurchased and cancelled 2,672,500 of our 7.401% $25 liquidation value preference shares (NYSE : AHL-PA) at a price of $12.50 per share. The repurchase resulted in a first quarter gain attributable to ordinary shareholders of approximately $31.5 million which was not recognized in the income statement but was included in the calculation of earnings per share.

The following table shows our capital structure at September 30, 2009 compared to December 31, 2008.

	As at		As at
	September 30, 2009		December 31, 2008
	($ in millions)
Share capital, additional paid-in capital and retained income and accumulated other comprehensive income attributable to ordinary shareholders	$	2,858.5	$	2,359.9
Preference shares (liquidation preference less issue expenses)		353.6		419.2
Long-term debt		249.6		249.5
Total capital	$	3,461.7	$	3,028.6

Management monitors the ratio of debt to total capital, with total capital being defined as shareholders’ equity plus outstanding debt. At September 30, 2009, this ratio was 7.2% (December 31, 2008 — 8.2%).

Our preference shares are classified in our balance sheet as equity but may receive a different treatment in some cases under the capital adequacy assessments made by certain rating agencies. Such securities are often referred to as ‘hybrids’ as they have certain attributes of both debt and equity. We also monitor the ratio of the total of debt and hybrids to total capital which was 17.4% as of September 30, 2009 (December 31, 2008 — 22.1%).

Access to capital.  Our business operations are in part dependent on our financial strength and the market’s perception thereof, as measured by shareholders’ equity, which was $3,212.1 million at September 30, 2009 (December 31, 2008 — $2,779.1 million). We believe our financial strength provides

58

us with the flexibility and capacity to obtain funds through debt or equity financing. Our continuing ability to access the capital markets is dependent on, among other things, our operating results, market conditions and our perceived financial strength. We regularly monitor our capital and financial position, as well as investment and securities market conditions, both in general and with respect to Aspen Holdings’ securities. Our ordinary shares and all our preference shares are listed on the New York Stock Exchange.

Liquidity

Liquidity is a measure of a company’s ability to generate cash flows sufficient to meet short-term and long-term cash requirements of its business operations. Management monitors the liquidity of Aspen Holdings and of each of its Insurance Subsidiaries and arranges credit facilities to enhance short-term liquidity resources on a stand-by basis.

Holding company.  We monitor the ability of Aspen Holdings to service debt, to finance dividend payments to ordinary and preference shareholders and to provide financial support to the Insurance Subsidiaries.

As at September 30, 2009, Aspen Holdings held $8.9 million (December 31, 2008 — $32.4 million) in cash and cash equivalents which management considers sufficient to provide Aspen Holdings liquidity at such time, taken together with dividends declared or expected to be declared by subsidiary companies and our credit facilities. Holding company liquidity depends on dividends, capital distributions and interest payments from our Insurance Subsidiaries.

In the nine months ended September 30, 2009, Aspen U.K. Holdings paid Aspen Holdings a dividend of $138.0 million. In the nine months ended September 30, 2008, Aspen Bermuda and Aspen U.K. Holdings paid Aspen Holdings dividends totaling $70.0 million. Aspen Holdings also received interest of $27.4 million (2008 — $27.4 million) from Aspen U.K. Holdings in respect of an intercompany loan.

The ability of our Insurance Subsidiaries to pay us dividends or other distributions is subject to the laws and regulations applicable to each jurisdiction, as well as the Insurance Subsidiaries’ need to maintain capital requirements adequate to maintain their insurance and reinsurance operations and their financial strength ratings issued by independent rating agencies. For a discussion of the various restrictions on our ability and our Insurance Subsidiaries’ ability to pay dividends, see Part I, Item 1 “Business — Regulatory Matters” in our 2008 Annual Report onForm 10-K filed with the United States Securities and Exchange Commission. Also for a more detailed discussion of our Insurance Subsidiaries’ ability to pay dividends see Note 15 of our annual financial statements in our 2008 Annual Report onForm 10-K filed with the United States Securities and Exchange Commission.

Insurance subsidiaries.  As of September 30, 2009, the Insurance Subsidiaries held approximately $939.9 million (December 31, 2008 — $777.2 million) in cash and short-term investments that are readily realizable securities. Management monitors the value, currency and duration of cash and investments held by its Insurance Subsidiaries to ensure that they are able to meet their insurance and other liabilities as they become due and was satisfied that there was a comfortable margin of liquidity as at September 30, 2009 and for the foreseeable future.

On an ongoing basis, our Insurance Subsidiaries’ sources of funds primarily consist of premiums written, investment income and proceeds from sales and redemptions of investments.

Cash is used primarily to pay reinsurance premiums, losses and loss adjustment expenses, brokerage commissions, general and administrative expenses, taxes, interest and dividends and to purchase new investments.

The potential for individual large claims and for accumulations of claims from single events means that substantial and unpredictable payments may need to be made within relatively short periods of time.

59

We manage these risks by making regular forecasts of the timing and amount of expected cash outflows and ensuring that we maintain sufficient balances in cash and short-term investments to meet these estimates. Notwithstanding this policy, if our cash flow forecast is incorrect, we could be forced to liquidate investments prior to maturity, potentially at a significant loss.

The liquidity of our Insurance Subsidiaries is also affected by the terms of our contractual obligations to policyholders and by undertakings to certain regulatory authorities to facilitate the issue of letters of credit or maintain certain balances in trust funds for the benefit of policyholders. The following table shows the forms of collateral or other security provided to policyholders as at September 30, 2009 and December 31, 2008:

	As at September 30,			As at December 31,
	2009			2008
	($ in millions except percentages)
Assets held in multi-beneficiary trusts	$	1,409.7		$	1,345.6
Assets held in single beneficiary trusts		55.9			54.0
Letters of credit issued under our revolving credit facilities (1)		59.3			84.6
Secured letters of credit (2)		412.3			422.4
Total	$	1,937.2		$	1,906.6
Total as % of cash and invested assets		29.4	%		33.1	%

(1)	These letters of credit are not secured by cash or securities, though we have the ability to issue secured letters of credit under the revolving credit facility.
(2)	As of September 30, 2009, the Company had funds on deposit of $588.7 million and £21.2 million (December 31, 2008 — $604.6 million and £25.3 million) as collateral for the secured letters of credit.

Funds at Lloyd’s.  AUL operates in Lloyd’s as the corporate member for Syndicate 4711. Lloyd’s determines Syndicate 4711’s required regulatory capital principally based on the syndicate’s annual business plan. Such capital, called Funds at Lloyd’s, comprises cash, investments and a fully collateralized letter of credit. The amounts of cash, investments and letter of credit at September 30, 2009 amount to $212.6 million (December 31, 2008 — $200.3 million).

Further information on these arrangements can be found in our 2008 Annual Report onForm 10-K filed with the United States Securities and Exchange Commission.

Consolidated cash flows for the nine months ended September 30, 2009.  Total net cash flow from operations from December 31, 2008 through September 30, 2009 was $489.1 million, an increase of $44.8 million over the comparative period. The increase was due mainly to an increase in premium receipts from increases in written premium net claims settlements. For the nine months ended September 30, 2009, our cash flow from operations provided us with sufficient liquidity to meet our operating requirements. On August 27, 2009, we paid a dividend of $0.15 per ordinary share to shareholders of record on August 12, 2009. On October 1, 2009, dividends totaling $3.2 million on our Perpetual Preferred Income Equity Replacement Securities (“Perpetual PIERS”) were paid to our dividend disbursing agent, for payment to our Perpetual PIERS holders of record on September 15, 2009. On October 1, 2009, dividends totaling $2.5 million on our Perpetual Non-Cumulative Preference Shares (“Perpetual Preference Shares”) were paid to our dividend disbursing agent, for payment to our Perpetual Preference Share holders of record on September 15, 2009.

Credit Facility.  On August 2, 2005, we entered into a five-year $400 million revolving credit facility pursuant to a credit agreement dated as of August 2, 2005 (the “credit facilities”) by and among the Company, certain of our direct and indirect subsidiaries, including the Insurance Subsidiaries (collectively, the “Borrowers”) the lenders party thereto, Barclays Bank plc, as administrative agent and letter of credit issuer, Bank of America, N.A. and Calyon, New York Branch, as co-syndication agents, Credit Suisse, Cayman Islands Branch and Deutsche Bank AG, New York Branch, as co-documentation agents and The Bank of New York, as collateral agent. On September 1, 2006, the aggregate limit available under the credit facility was increased to $450 million.

60

The facility can be used by any of the Borrowers to provide funding for our Insurance Subsidiaries, to finance the working capital needs of the Company and our subsidiaries and for general corporate purposes of the Company and our subsidiaries. The revolving credit facility provides for a $250 millionsub-facility for collateralized letters of credit. The facility will expire on August 2, 2010. As of September 30, 2009, no borrowings were outstanding under the credit facilities, though we had $59.3 million of outstanding uncollateralized letters of credit. The fees and interest rates on the loans and the fees on the letters of credit payable by the Borrowers increase based on the consolidated leverage ratio of the Company.

Under the credit facilities, we must maintain at all times a consolidated tangible net worth of not less than approximately $1.1 billion plus 50% of consolidated net income and 50% of aggregate net cash proceeds from the issuance by the Company of its capital stock, each as accrued from January 1, 2005. On June 28, 2007, we amended the credit agreement to permit dividend payments on existing and future hybrid capital notwithstanding a default or an event of default under the credit agreement. On April 13, 2006, the agreement was amended to remove any downward adjustment on maintaining the Company’s consolidated tangible net worth in the event of a net loss. The Company must also not permit its consolidated leverage ratio of total consolidated debt to consolidated tangible net worth to exceed 35%. In addition, the credit facilities contain other customary affirmative and negative covenants as well as certain customary events of default, including with respect to a change in control. The various affirmative and negative covenants, include, among others, covenants that, subject to important exceptions, restrict the ability of the Company and its subsidiaries to: create or permit liens on assets; engage in mergers or consolidations; dispose of assets; pay dividends or other distributions, purchase or redeem the Company’s equity securities or those of its subsidiaries and make other restricted payments; permit the rating of any insurance subsidiary to fall below A.M. Best financial strength rating of B++ or Standard & Poor’s (“S&P”) financial strength rating of A-; make certain investments; agree with others to limit the ability of the Company’s subsidiaries to pay dividends or other restricted payments or to make loans or transfer assets to the Company or another of its subsidiaries. The credit facilities also include covenants that restrict the ability of our subsidiaries to incur indebtedness and guarantee obligations.

On April 29, 2009, Aspen Bermuda replaced its existing letter of credit facility with Citibank Europe dated October 29, 2008 in a maximum aggregate amount of up to $450 million with a new letter of credit facility in a maximum aggregate amount of up to $550 million. As at September 30, 2009 we had $395.9 million of outstanding collateralized letters of credit under this facility.

On October 6, 2009, Aspen U.K. and Aspen Bermuda entered into a $200 million secured letter of credit facility with Barclays Bank plc, which is described on our current report on Form 8-K filed on October 7, 2009. No letters of credit were outstanding under this facility as at September 30, 2009.

Contractual Obligations and Commitments

The following table summarizes our contractual obligations (other than our obligations to employees, our Perpetual PIERS and our Perpetual Preference Shares) under long-term debt, operating leases and reserves relating to insurance and reinsurance contracts as of September 30, 2009:

											Later
	2009		2010		2011		2012		2013		Years		Total
	($ in millions)

Long-Term Debt Obligations (1)		—		—		—		—		—	$	250.0	$	250.0
Reserves for Losses and loss adjustment expenses (2)	$	154.0	$	931.0	$	608.4	$	398.2	$	273.6	$	948.8	$	3,314.0

(1)

The long-term debt obligations disclosed above do not include the $15 million annual interest payments on our outstanding senior notes.

(2)

In estimating the time intervals into which payments of our reserves for losses and loss adjustment expenses fall, as set out above, we have utilized actuarially assessed payment patterns. By the nature of the insurance and reinsurance contracts under which these liabilities are assumed, there can be no certainty that actual payments will fall in the periods shown and there could be a material acceleration or deceleration of claims payments depending on factors outside our control. This uncertainty is heightened by the short time in which we have operated, thereby providing limited Company-specific claims loss payment patterns. The total amount of payments in respect of our reserves, as well as the timing of such payments, may differ materially from our current estimates for the reasons set out above under “— Critical Accounting Policies-Reserves for Losses and Loss Expenses.”

61

Further information on operating leases is given in our 2008 Annual Report onForm 10-K filed with the United States Securities and Exchange Commission.

For a discussion of derivative instruments we have entered into, please see Note 8 to our unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2009 included elsewhere in this report.

Off-Balance Sheet Arrangements

Ajax Re.  Ajax Re was a variable interest entity under the guidance contained in ASC 820Consolidations. We had a variable interest in the entity, however we were not the primary beneficiary of the entity and therefore we were not required to consolidate its results into our consolidated financial statements. For further details on the Ajax Re transactions please see Note 7 to the unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2009 included elsewhere in this report.

We are not party to any transaction, agreement or other contractual arrangement to which an affiliated entity unconsolidated with us is a party, other than that noted above with Ajax Re, that management believes is reasonably likely to have a current or future effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Cartesian Iris 2009A L.P.  Cartesian Iris 2009A L.P. is a variable interest entity under the guidance contained in ASC 820Consolidations. On May 19, 2009 we invested $25.0 million with Cartesian Iris 2009A L.P. through our wholly owned subsidiary, Acorn Limited. Cartesian Iris 2009A L.P. is a Delaware Limited Partnership formed to provide capital to Iris Re, a newly formed Class 3 Bermuda reinsurer focusing on insurance linked securities. In addition to returns on our investment, we will receive a fee for providing advice on risk selection, pricing and portfolio design. In the three and nine months ended September 30, 2009, a fee of $0.1 million was payable to Aspen. For more information please see Note 5 and 12(c) to the unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2009 included elsewhere in this report.

Effects of Inflation

Inflation may have a material effect on our consolidated results of operations by its effect on interest rates and on the cost of settling claims. The potential exists, after a catastrophe or other large property loss, for the development of inflationary pressures in a local economy as the demand for services such as construction typically surges. We believe this had an impact on the cost of claims arising from the 2005 hurricanes. The cost of settling claims may also be increased by global commodity price inflation. We seek to take both these factors into account when setting reserves for any events where we think they may be material.

Our calculation of reserves for losses and loss expenses in respect of casualty business includes assumptions about future payments for settlement of claims and claims-handling expenses, such as medical treatments and litigation costs. We write casualty business in the United States, the United Kingdom and Australia and certain other territories, where claims inflation has in many years run at higher rates than general inflation. To the extent inflation causes these costs to increase above reserves established for these claims, we will be required to increase our loss reserves with a corresponding reduction in earnings. The actual effects of inflation on our results cannot be accurately known until claims are ultimately settled.

In addition to general price inflation we are exposed to a persisting long-term upwards trend in the cost of judicial awards for damages. We seek to take this into account in our pricing and reserving of casualty business.

62

We also seek to take into account the projected impact of inflation on the likely actions of central banks in the setting of short-term interest rates and consequent effects on the yields and prices of fixed interest securities. We consider that although inflation is currently low, in the medium-term there is a risk that inflation, interest rates and bond yields will rise with the result that the market value of certain of our fixed interest investments may reduce.

Cautionary Statement Regarding Forward-Looking Statements

ThisForm 10-Q contains, and the Company may from time to time make other verbal or written, forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended, that involve risks and uncertainties, including statements regarding our capital needs, business strategy, expectations and intentions. Statements that use the terms “believe,” “do not believe,” “anticipate,” “expect,” “plan,” “estimate,” “project,” “seek,” “will,” “may,” “aim,” “continue,” “intend,” “guidance” and similar expressions are intended to identify forward-looking statements. These statements reflect our current views with respect to future events and because our business is subject to numerous risks, uncertainties and other factors, our actual results could differ materially from those anticipated in the forward-looking statements. The risks, uncertainties and other factors set forth in the Company’s 2008 Annual Report onForm 10-K filed with the Securities and Exchange Commission and other cautionary statements made in this report, as well as the following factors, should be read and understood as being applicable to all related forward-looking statements wherever they appear in this report.

All forward-looking statements address matters that involve risks and uncertainties. Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in these statements. We believe that these factors include, but are not limited to, the following:

•  the continuing and uncertain impact of the current depressed credit environment, the banking crises and economic recessions in many of the countries in which we operate and of the measures being taken by governments to counter these issues;

•  the risk of a material decline in the value or liquidity of all or parts of our investment portfolio;

•  changes in insurance and reinsurance market conditions;

•  changes in our ability to exercise capital management initiatives or to arrange banking facilities as a result of prevailing market changes or changes in our financial position;

•  our ability to execute our business plan to enter new markets, introduce new products and develop new distribution channels, including their integration into our existing operations;

•  increased counterparty risk due to the impairment of financial institutions;

•  changes in the total industry losses, or our share of total industry losses, resulting from past events such as Hurricanes Ike and Gustav and, with respect to such events, our reliance on loss reports received from cedants and loss adjustors, our reliance on industry loss estimates and those generated by modeling techniques, changes in rulings on flood damage or other exclusions as a result of prevailing lawsuits and case law, any changes in our reinsurers’ credit quality and the amount and timing of reinsurance recoverables;

•  the impact of acts of terrorism and related legislation and acts of war;

•  the possibility of greater frequency or severity of claims and loss activity, including as a result of natural or man-made (including economic and political risks) catastrophic events, than our underwriting, reserving, reinsurance purchasing or investment practices have anticipated;

•  evolving interpretive issues with respect to coverage after major loss events;

63

•  the level of inflation in repair costs due to limited availability of labor and materials after catastrophes;

•  the effectiveness of our loss limitation methods;

•  changes in the availability, cost or quality of reinsurance or retrocessional coverage;

•  the reliability of, and changes in assumptions to, natural and man-made catastrophe pricing, accumulation and estimated loss models;

•  loss of key personnel;

•  a decline in our operating subsidiaries’ ratings with S&P, A.M. Best or Moody’s Investor Service;

•  changes in general economic conditions, including inflation, foreign currency exchange rates, interest rates and other factors that could affect our investment portfolio;

•  increased competition on the basis of pricing, capacity, coverage terms or other factors and the related demand and supply dynamics as contracts come up for renewal;

•  decreased demand for our insurance or reinsurance products and cyclical changes in the insurance and reinsurance sectors;

•  changes in government regulations or tax laws in jurisdictions where we conduct business; and

•  Aspen Holdings or Aspen Bermuda becoming subject to income taxes in the United States or the United Kingdom.

In addition, any estimates relating to loss events involve the exercise of considerable judgment and reflect a combination ofground-up evaluations, information available to date from brokers and cedants, market intelligence, initial tentative loss reports and other sources. Due to the complexity of factors contributing to the losses and the preliminary nature of the information used to prepare estimates, there can be no assurance that our ultimate losses will remain within the stated amounts.

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 this report. We undertake no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise or disclose any difference between our actual results and those reflected in such statements.

If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we projected. Any forward-looking statements you read in this report reflect our current views with respect to future events and are subject to these and other risks, uncertainties and assumptions relating to our operations, results of operations, growth strategy and liquidity. All subsequent written and oral forward-looking statements attributable to us or individuals acting on our behalf are expressly qualified in their entirety by the points made above. You should specifically consider the factors identified in this report which could cause actual results to differ before making an investment decision.

Item 3.   Quantitative and Qualitative Disclosures about Market Risk

Interest rate risk.  Our investment portfolio consists primarily of fixed income securities. Accordingly, our primary market risk exposure is to changes in interest rates. Fluctuations in interest rates have a direct impact on the market valuation of these securities. As interest rates rise, the market value of our fixed-income portfolio falls, and the converse is also true. Our strategy for managing interest rate risk includes maintaining a high quality portfolio with a relatively short duration to reduce the effect of interest rate changes on book value.

As at September 30, 2009, our fixed income portfolio had an approximate duration of 3.3 years. The table below depicts interest rate change scenarios and the effect on our interest-rate sensitive invested assets:

Effect of Changes in Interest Rates on Portfolio Given a Parallel Shift in the Yield Curve
Movement in Rates in Basis Points	−100			−50			0			50			100
	($ in millions, except percentages)
Market value $ in millions	$	5,799.0		$	5,707.4		$	5,615.9		$	5,524.4		$	5,432.8
Gain/(loss) $ in millions		183.1			91.5			0.0			(91.5	)		(183.1	)
Percentage of portfolio		3.26	%		1.63	%		0.00	%		(1.63	)%		(3.26	)%

Equity risk.  We had invested in two funds of hedge funds where the underlying hedge funds consisted of diverse strategies and securities. In February 2009, we gave notice to redeem our remaining investments in funds of hedge funds with effect on June 30, 2009, which would reduce our exposure to equity risk. As the notices of redemption have taken effect, we are no longer exposed to changes in the net asset value of the funds.

Foreign currency risk.  Our reporting currency is the U.S. Dollar. The functional currencies of our segments are U.S. Dollars, British Pounds, Euros, Swiss Francs, Australian Dollars and Singaporean Dollars. As of September 30, 2009, approximately 83% of our cash, cash equivalents and investments were held in U.S. Dollars, approximately 8% were in British Pounds and approximately 9% were in other currencies. For the nine months ended September 30, 2009, approximately 17% of our gross premiums were written in currencies other than the U.S. Dollar and the British Pound and we expect that a similar proportion will be written in currencies other than the U.S. Dollar and the British Pound in the remainder of 2009. Other foreign currency amounts are re-measured to the appropriate functional currency and the resulting foreign exchange gains or losses are reflected in the statement of operations. Functional currency amounts of assets and liabilities are then translated into U.S. Dollars. The unrealized gain or loss from this translation, net of tax, is recorded as part of shareholders’ equity. The change in unrealized foreign currency translation gain or loss during the period, net of tax, is a component of comprehensive income. Both the re-measurement and translation are calculated using current exchange rates for the balance sheets and average exchange rates for the statement of operations. We may experience exchange losses to the extent our foreign currency exposure is not hedged, which in turn would adversely affect our results of operations and financial condition. Management estimates that a 10% change in the exchange rate between British Pounds and U.S. Dollars as at September 30, 2009, would have impacted reported net comprehensive income by approximately $18.1 million for the nine months ended September 30, 2009. We manage our foreign currency risk by seeking to match our liabilities under insurance and reinsurance policies that are payable in foreign currencies with investments that are denominated in these currencies. This may involve the use of forward exchange contracts from time to time. A forward exchange contract involves an obligation to purchase or sell a specified currency at a future date at a price set at the time of the contract. Foreign currency exchange contracts will not eliminate fluctuations in the value of our assets and liabilities denominated in foreign currencies, but rather allows us to establish a rate of exchange for a future point in time. All realized gains and losses on foreign exchange forward contracts are recognized in the Statements of Operations. There were no outstanding foreign currency

contracts at September 30, 2009 compared to $90.5 million of U.S. and foreign currency contracts at September 30, 2008.

Credit risk.  We have exposure to credit risk primarily as a holder of fixed income securities. Our risk management strategy and investment policy is to invest in debt instruments of high credit quality issuers and to limit the amount of credit exposure with respect to particular ratings categories, business sectors and any one issuer. As at September 30, 2009 and December 31, 2008, the average rating of fixed income securities in our investment portfolio was “AA+ and AAA”, respectively.

In addition, we are exposed to the credit risk of our insurance and reinsurance brokers to whom we make claims payments for our policyholders, as well as to the credit risk of our reinsurers and retrocessionaires who assume business from us. Other than fully collateralized reinsurance the substantial majority of our reinsurers have a rating of “A” (Excellent), the third highest of fifteen rating levels, or better by A.M. Best and the minimum rating of any of our material reinsurers is “A−” (Excellent), the fourth highest of fifteen rating levels, by A.M. Best.

We have also entered into a credit insurance contract which, subject to its terms, insures us against losses due to the inability of one or more of our reinsurance counterparties to meet their financial obligations to the Company. Payments are made on a quarterly basis throughout the period of the contract based on the aggregate limit, which was set initially at $477 million but is subject to adjustment. See Note 8 to the unaudited financial statements for the three months ended September 30, 2009 above.

The table below shows our reinsurance recoverables as of September 30, 2009 and December 31, 2008, and our reinsurers’ ratings.

Item 4.   Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the design and operation of the Company’s disclosure controls and procedures as of the end of the period of this report. Our management does not expect that our disclosure controls or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. As a result of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons or by collusion of two or more people. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. As a result of the inherent limitations in a cost-effective control system, misstatement due to error or fraud may occur and not be detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the disclosure requirements are met. Based on the evaluation of the disclosure controls and procedures, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective in ensuring that information required to be disclosed in the reports filed or submitted to the Commission under the Exchange Act by the Company is recorded, processed, summarized and reported in a timely fashion, and is accumulated and communicated to management, including the Company’s Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

The Company’s management has performed an evaluation, with the participation of the Company’s Chief Executive Officer and the Company’s Chief Financial Officer, of changes in the Company’s internal control over financial reporting that occurred during the quarter ended September 30, 2009. Based upon that evaluation, the Company’s management is not aware of any change in its internal control over financial reporting that occurred during the quarter ended September 30, 2009 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
