This financial supplement is for information purposes only. It should be read in conjunction with other documents filed or to be filed shortly by Aspen Insurance Holdings Limited (the ‘‘Company’’ or ‘‘Aspen’’) with the United States Securities and Exchange Commission.

BASIS OF PREPARATION

Definitions and presentation:    All financial information contained herein is unaudited except for information for the fiscal year ended December 31, 2006. Unless otherwise noted, all data is in US dollars millions, except for per share, percentage and ratio information.

In presenting the Company’s results, management has included and discussed certain ‘‘non-GAAP financial measures’’, as such term is defined in Regulation G. Management believes that these non-GAAP measures, which may be defined differently by other companies, better explain the Company’s results of operations in a manner that allows for a more complete understanding of the underlying trends in the Company’s business. However, these measures should not be viewed as a substitute for those determined in accordance with GAAP. The reconciliation of such non-GAAP financial measures to their respective most directly comparable GAAP financial measures in accordance with Regulation G is included in this financial supplement.

Operating income (a non-GAAP financial measure):    Operating income is an internal performance measure used by the Company in the management of its operations and represents after-tax operational results excluding, as applicable, after-tax net realized capital gains or losses and after-tax net foreign exchange gains or losses.

The Company excludes after-tax net realized capital gains or losses and after-tax net foreign exchange gains or losses from its calculation of operating income because the amount of these gains or losses is heavily influenced by, and fluctuates in part, according to the availability of market opportunities. The Company believes these amounts are largely independent of its business and underwriting process and including them distorts the analysis of trends in its operations. In addition to presenting net income determined in accordance with GAAP, the Company believes that showing operating income enables investors, analysts, rating agencies and other users of its financial information to more easily analyze the Company’s results of operations in a manner similar to how management analyzes the Company’s underlying business performance. Operating income should not be viewed as a substitute for GAAP net income. Please see page 22 for a reconciliation of operating income to net income.

Annualized Operating Return on Average Equity (‘‘Operating ROAE’’) (a non-GAAP financial measure):    Annualized Operating Return on Average Equity 1) is calculated using operating income, as defined above and 2) excludes from average equity, the average after-tax unrealized appreciation or depreciation on investments and the average after-tax unrealized foreign exchange gains or losses and the aggregate value of the liquidation preferences of our preference shares. Unrealized appreciation (depreciation) on investments is primarily the result of interest rate movements and the resultant impact on fixed income securities, and unrealized appreciation (depreciation) on foreign exchange is the result of exchange rate movements between the U.S. dollar and the British pound. Such appreciation (depreciation) is not related to management actions or operational performance (nor is it likely to be realized). Therefore the Company believes that excluding these unrealized appreciations (depreciations) provides a more consistent and useful measurement of operating performance, which supplements GAAP information. Average equity is calculated as the arithmetic average on a monthly basis for the stated periods. The Company presents Operating ROAE as a measure that is commonly recognized as a standard of performance by investors, analysts, rating agencies and other users of its financial information. See page 22 for a reconciliation of operating income to net income and page 15 for a reconciliation of average equity.

Diluted book value per ordinary share (a non-GAAP financial measure):    The Company has included diluted book value per ordinary share because it takes into account the effect of dilutive securities; therefore, the Company believes it is a better measure of calculating shareholder returns than book value per share. Please see page 22 for a reconciliation of diluted book value per share to basic book value per share.

Underwriting ratios (GAAP financial measures):    The Company, along with others in the industry, uses underwriting ratios as measures of performance. The loss ratio is the ratio of net claims and claims adjustment expenses to net premiums earned. The acquisition expense ratio is the ratio of underwriting expenses (commissions; premium taxes, licenses and fees; as well as other underwriting expenses) to net premiums earned. The general and administrative expense ratio is the ratio of general and administrative expenses to net premiums earned. The combined ratio is the sum of the loss ratio, the acquisition expense ratio and the general and administrative expense ratio. These ratios are relative measurements that describe for every $100 of net premiums earned or written, the cost of losses and expenses, respectively. The combined ratio presents the total cost per $100 of earned premium. A combined ratio below 100% demonstrates underwriting profit; a combined ratio above 100% demonstrates underwriting loss.

GAAP combined ratios differ from US statutory combined ratios primarily due to the deferral of certain third party acquisition expenses for GAAP reporting purposes and the use of net premiums earned rather than net premiums written in the denominator when calculating the acquisition expense and the general and administrative expense ratios.
