Segment—Key Component

Financial Guaranty Profile

Through its Financial Services segment, the Company is an active participant in the financial guaranty market. The Company’s financial guaranty exposure comprises exposure to municipal and non-municipal obligations. At March 31, 2003, the Company had total financial guaranty exposure outstanding of $82.6 billion of which 60.0 percent represented exposure to municipal obligations and 40.0 percent to non-municipal obligations.

The financial guaranty portfolio is broadly diversified by payment source, geographic location, and maturity schedule. The Company limits its exposure to losses by underwriting primarily investment grade obligations. The following details the composition of the Company’s financial guaranty business:

	March 31, 2003				December 31, 2002

Total Exposure	$	82,597	100%		$	81,765	100.0%

(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 (CDOs) 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.

ACE Limited

Segment—Key Component

Financial Guaranty Profile

The greatest proportion of the Company’s municipal financial guaranty exposure (23.7%), comprises general obligation bonds that are supported by the issuer’s taxing authority and of special revenue bonds and other special obligations of states and local governments that are supported by the issuer’s ability to impose and collect fees and charges for public services or specific projects. Maturities for municipal obligations can range from one to 30 years, with the average maturity in the 12-15 year range. The weighted average credit quality of the municipal portfolio was A as of March 31, 2003.

The Company’s non-municipal exposure includes exposure to asset-backed obligations, including those backed by consumer receivables, commercial receivables and collateralized debt obligations (“CDOs”) as well as single name corporate obligations. Legal maturities for non-municipal transactions range from 1-30 years. Maturities of single name corporate credit default swaps (CDS) range from 1-5 years with an average maturity of 1.8 years. The weighted average credit quality of the non-municipal portfolio was AA- as of March 31, 2003.

The Company conducts its financial guaranty business by entering into insurance and reinsurance arrangements as well as CDS. Exposure to CDS included in total exposure amounted to $21.5 billion and $20.7 billion at March 31, 2003 and December 31, 2002, respectively. The Company’s principal CDS exposure is to CDOs and single name corporate obligations. The preponderance of the Company’s CDO exposure is highly rated senior layer CDOs. Senior Layer CDOs are structured with first loss protection in the form of subordination or over collateralization so that the Company’s risk typically attaches at or above the AAA rating level. The Company also participates in Funded Equity CDO transactions wherein a substantial portion of the Company’s exposure is mitigated by premium. Rate on line for such transactions is typically 75%-85% of the total exposure.

Ratings distributions of the Company’s senior layer CDOs and single name corporate credit default swaps as of March 31, 2003 are shown below:

	A	AA	AAA	BBB	BIG
Senior Layer CDOs	7.2%	15.5%	70.2%	6.2%	0.9%
Single Name Corporate CDS	49.7%	18.5%	17.3%	11.1%	3.4%

Financial Guaranty Profile

Because credit default swaps are considered derivative transactions under FAS 133, the Company is required to mark-to-market its outstanding exposure at each financial reporting date. This is in contrast to the accounting treatment for a similar risk that is written as an insurance contract and is required in spite of the fact that the Company does not trade its credit default swap positions. Rather, its business is analogous to a buy and hold strategy. The mark-to-market adjustment reflects the estimated cost to the Company to purchase mirror protection on its outstanding exposures and is not an estimate of expected losses incurred. Expected losses are provided for in outstanding loss reserves, which the Company believes are adequate. In the first quarter, the Company recorded a FAS 133 mark-to-market loss before tax of $2.1 million.

The following table summarizes the Company's scheduled outstanding credit default swap portfolio by year as of March 31, 2003:

($ billions)	2003		2004		2005		2006		2007		Thereafter

As illustrated in the table above, it is important to consider the composition of the recoverable balance and the related exposures in three components: Brandywine, Westchester and Active Operations recoverable. Active operations include the run-off operations of CIS. Additional information on reinsurance recoverable on a consolidated basis and for active operations for December 31, 2002 can be found on pages 25 and 26, respectively.

The Company's obligations with respect to further funding of the Brandywine runoff are limited pursuant to the Brandywine Restructuring Order under an $800 million aggregate excess of loss reinsurance agreement. (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 recently filed Form 10-K for the year ended December 31, 2002 for additional information about the order and other Company obligations.) At December 31, 2002, approximately $466 million in losses and recoverable bad debt reserves were ceded to the aggregate excess of loss reinsurance agreement leaving a remaining limit of approximately $334 million.

As part of the Westchester acquisition, National Indemnity provided reinsurance protection for all losses occurring prior to 1997. At December 31, 2002, the remaining limit in the reinsurance cover was approximately $600 million.

The remaining balance of reinsurance recoverable consist of recoverables primarily associated with active operations.

(1) General collections balances represent amounts in process of collection in the normal course of business, for which we have no indication of dispute or credit issues. We provide bad debt reserves based primarily on the application of historical loss experience to credit categories and historical dispute statistics.

(2) Other includes amounts recoverable that are in dispute, or are from companies who are in supervision, rehabilitation or liquidation. Our estimation of this reserve considers the credit quality of the reinsurer, and whether we have received collateral or other credit protections such as parental guarantees. In addition, we also consider any information we may have regarding the reinsurers plans to dispute amounts recoverable and make judgements based on our knowledge and experience regarding the specific items in dispute.

Reconciliation to Generally Accepted Accounting Principles

Regulation G—Non-GAAP Financial Measures

In presenting our operating results, we have included and discussed certain non-GAAP measures. These non-GAAP measures, which may be defined differently by other companies, are important to an understanding of our overall results of operations; however, they should not be viewed as a substitute for measures determined in accordance with GAAP. Net operating income (loss) is a common performance measurement and is defined as net income (loss) excluding net realized gains (losses) on investments, the tax effect of net realized gains (losses) on investments and the cumulative effect of adopting a new accounting standard, net of income tax. We believe this presentation of net operating income (loss) 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 from net operating income (loss) because the amount of these gains (losses) is heavily influenced by, and fluctuates in part, according to the availability of market opportunities. The cumulative effect of adopting a new accounting standard is excluded from our calculation of net operating income (loss). We believe these amounts are largely independent of our business and including them would distort the analysis of trends. Net operating income (loss) should not be viewed as a substitute for net income determined in accordance with generally accepted accounting principles (GAAP).
