	Any forward-looking statements made in this financial supplement reflect the Company’s current views with respect to future events and financial performance and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such statements involve risks and uncertainties which may cause actual results to differ materially from those set forth in these statements. For example, the Company’s forward-looking statements, such as statements concerning exposures, reserves and recoverables, could be affected by the frequency of unpredictable catastrophic events, actual loss experience, uncertainties in the reserving or settlement process, new theories of liability, judicial, legislative and other governmental developments, litigation tactics, the amount and timing of reinsurance receivable and credit developments among reinsurers. The Company’s forward-looking statements could also be affected by competition, pricing and policy term trends, the levels of new and renewal business achieved, market acceptance, changes in demand, actual market developments, rating agency action, possible terrorism or the outbreak and effects of war and economic, political, regulatory, insurance and reinsurance business conditions, as well as management’s response to these factors. Other factors that could affect forward-looking statements are identified in the Company’s filings with the Securities and Exchange Commission, including the Company’s Annual Report on Form 10-K for the year ended December 31, 2004, the Company’s quarterly reports on Form 10-Q and in the Company’s earnings press release, which are available on the Company’s website.
	Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the dates on which they are made. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

ACE Limited   Non-GAAP Financial Measures   (in millions of U.S. dollars)   (Unaudited)

Regulation G - Non-GAAP Financial Measures

In presenting our results, we have included and discussed certain non-GAAP measures. These non-GAAP measures, which may be defined differently by other companies, are important for an understanding of our overall results of operations; however, they should not be viewed as a substitute for measures determined in accordance with GAAP. A reconciliation of book value per share to diluted book value per ordinary share is provided on page 22.

In presenting our segment operating results we have shown our performance with reference to underwriting results. Underwriting results are calculated by subtracting losses and loss expenses, life and annuity benefits, policy acquisition costs and administrative expenses from net premiums earned. We use underwriting results and operating ratios to monitor the results of our operations without the impact of certain factors, including investment income, other income and expenses, interest and income tax expense and net realized gains (losses).

The following non-GAAP measure is a common performance measurement and is defined as income (loss) excluding net realized gains (losses) and the tax expense on net realized gains (losses). We believe this presentation enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. We exclude net realized gains (losses) because the amount of these gains (losses) is heavily influenced by, and fluctuates in part, according to the availability of market opportunities. We believe these amounts are largely independent of our business and including them would distort the analysis of trends. Income excluding net realized gains (losses) should not be viewed as a substitute for net income determined in accordance with generally accepted accounting principles (GAAP).
