	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 concerning exposures, reserves and recoverables could be affected by the frequency of unpredictable catastrophic events, actual loss experience which differs from the Company’s assumptions, uncertainties in the reserving or settlement process, new theories of liability, planned public offerings, judicial and legislative developments, litigation tactics, credit developments among reinsurers and the Company’s forward-looking statements concerning the maturity profile of CDO’s could change if a transaction is unwound early and settlement is reached. 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, 2003, 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.

⁽¹⁾ Structured Municipal: includes excess of loss reinsurance on portfolios of municipal credits where the company attached in excess of the AAA rating level.

⁽²⁾ Other Municipal: primarily includes first mortgage bonds on investor-owned utilities and government-sponsored project finance.

⁽³⁾ For ACE, collateralized debt obligations (CDO’s) are structured financings backed by a pool of investment grade assets. These financings are typically structured in multiple tranches (layers) from equity (first loss) through super senior (high excess). Losses on defaulted pool assets are allocated successively first to the equity tranche then to higher rated tranches. Market supply and demand factors influence pricing and the amount and position in the structure where ACE chooses to participate.

⁽⁴⁾ Consumer Receivables: principally includes auto loan receivables, residential mortgage-backed securities and credit card receivables.

⁽⁵⁾ Commercial Receivables: principally includes equipment leases and commercial mortgage-backed securities.

⁽⁶⁾ Other Structured Finance: predominantly trade receivable securitization, secured structured lending, and future flow transactions.

⁽⁷⁾ Gross par approximates net par as the company is a net line writer.

Note - Ratings are internally determined based on rating agency guidelines

⁽¹⁾ Active operations include the run-off operations of CIS and certain other divisions.

⁽²⁾ The Active operations’ obligations with respect to further funding of the run-off of Century Indemnity Company, a Brandywine subsidiary, are limited under the Brandywine Restructuring Order (the “Order”). Under the Order, the Company provided $800 million aggregate excess of loss reinsurance agreement, with respect to the Brandywine Runoff. (Refer to the “Asbestos and Environmental Claims” section of the “Management’s Discussion and Analysis of Financial Conditions and Results of Operations” incorporated into our filed Form 10-K for the year ended December 31, 2003 for additional information about the Order and other Company obligations.) At March 31, 2004, approximately $466 million in losses and recoverable bad debt reserves were ceded by Century to the aggregate excess of loss reinsurance agreement.

⁽³⁾ As part of the Westchester acquisition, National Indemnity provided reinsurance protection for all losses occurring prior to 1997. At December 31, 2003, the remaining unimpaired limit in the reinsurance cover was approximately $600 million.

Non-GAAP Financial Measures

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 33. The following non-GAAP measure is a common performance measurement and is defined as income (loss) excluding net realized gains (losses) on investments and the tax effect of net realized gains (losses) on investments. 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) on investments 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).
