Ace Limited Reports Third Quarter Results

Net premiums written increased 4% to $2.3 billion for the quarter. Out of total net premiums written, consolidated property and casualty increased by 27%, while Financial Services declined 78% reflecting the erratic nature of production in this segment. Most of this decline was due to the absence of new loss portfolio transfer and equity CDO premium for the quarter.

Brian Duperreault, Chairman and Chief Executive Officer of ACE Limited commented: "This was another excellent quarter for our Company that once again demonstrated the growing strength of our organization, our global presence and diversified product capability. ACE recorded increased income before net realized gains (losses) in every operating segment for the quarter. We remain optimistic about business conditions for the balance of the year and beyond."

Other operating highlights were as follows:

-- The P&C combined ratio was 91.6% for the quarter compared with 98.0% a year ago

-- Current quarter catastrophe losses totaled $42 million or 1.9% of P&C earned premiums for the quarter, compared with $100 million, or 6.7% of P&C earned premiums in the comparable quarter of 2002

-- Operating cash flow amounted to $1.1 billion for the quarter

-- Net investment income increased 9% to $216 million

-- Diluted book value per ordinary share increased to $27.76 from $24.16 at December 30, 2002, up 15% (2)

Shareholders' equity is $8.3 billion, an increase of 31% from December 31, 2002. Tangible equity amounted to $5.6 billion, a gain of 53% in the first nine months. Total capital resources were $10.7 billion as of September 30, 2003. ACE's debt to total capital ratio improved to 17.7%. Income before net realized gains as a percent of average equity, including the application of FAS 115, on an annualized basis totaled 15.2% for the quarter, and 16.8% excluding FAS 115.

Financial results improved over the prior year's results for each segment; details are available in the financial supplement. Key items include:

-- Insurance-North American: Net premiums written rose 23% in the quarter and the combined ratio was 91.9% reflecting the positive contributions made by the major business units.

-- Insurance-Overseas General: Net premiums written were up 26% as reported and 19% excluding the effect of foreign exchange. The foreign exchange impact on earnings was minimal. The segment's combined ratio improved to 92.9%. We are experiencing particularly strong results in our European and Asia Pacific operations.

-- Global Reinsurance: Net premiums written were up 66%, a result of our continued strategy to diversify our reinsurance operations into a multi-line reinsurer. This segment had an excellent combined ratio of 75.0% in the quarter. The company is developing its casualty reinsurance market with segment net premium written year-to-date of $1 billion. We incurred catastrophe losses of $12 million in the quarter.

-- Financial Services: Net premiums written were $105 million in the third quarter of 2003, principally arising from the Financial Guaranty business. Income excluding net realized gains (losses) was up 19% in the quarter. The segment had a $26 million pre-tax realized gain on its FAS 133 mark-to-market and reported a combined ratio of 89.5% for the third quarter.

(1) Income (loss) excluding net realized gains (losses) on investments and the tax effect of net realized gains (losses) on investments is a common performance measurement. 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. This measure should not be viewed as a substitute for net income determined in accordance with generally accepted accounting principles(GAAP).

(2) Diluted book value per ordinary share is ordinary shareholders' equity and net proceeds from assumed conversions of outstanding in-the-money options divided by the sum of shares outstanding and the number of options assumed issued.
