Evan G. Greenberg, Chairman and Chief Executive Officer of ACE Limited, stated: “ACE had a good first quarter, marked by strong operating and net income, with all divisions of the company making a positive contribution to results. Book value grew 2% and our ROE was over 18%.

“The strong U.S. dollar had a substantial and negative impact on our P&C premium revenue, which grew 7% in the quarter after adjusting for foreign exchange. We benefited from a generally firming market, particularly in our P&C reinsurance and global retail P&C insurance businesses. We also continued to benefit from the consolidation of Combined Insurance Company in our results.

“As the year goes on, I expect revenue growth to remain under pressure due to global recessionary conditions and foreign exchange. While many of our customers’ exposures are down due to reduced business activity, and many companies are in search of more affordable insurance alternatives, the quality of our portfolio of risks continues to improve given the firming pricing environment and the client flight to capability of a company like ACE.”

Other operating highlights were as follows:

• Net premiums written and earned increased 9%. Excluding the impact of foreign exchange, net premiums written and earned increased 15% and 16%, respectively.

• Net P&C premiums written and earned, which include international accident and health (A&H), increased 1%. Excluding the impact of foreign exchange, net P&C premiums written and earned increased 7%.

• Operating cash flow was $562 million, down 45%, due to large claim payment activity.

• Net loss reserves increased $103 million, excluding foreign exchange revaluation.

• Net investment income increased 3% to $502 million.

• Return on average equity was 18.4%.⁽³⁾

• Book value increased $272 million, or 2%, from December 31, 2008, while book value per share⁽⁴⁾ increased from $43.30 at December 31, 2008, to $43.82, or 1%.

⁽²⁾ Non-GAAP Financial Measures:

Operating Income or Income excluding net realized gains (losses), net of tax is a common performance measurement for insurance companies. 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) and net realized gains (losses) included in Other (income) expense related to partially-owned insurance companies because the amount of these gains (losses) do not relate to their respective operations.

Underwriting income is calculated by subtracting losses and loss expenses, policy benefits, policy acquisition costs and administrative expenses from net premiums earned. We use underwriting income and operating ratios to monitor the results of our operations without the impact of certain factors, including net investment income, other income (expense), interest and income tax expense and net realized gains (losses). We believe the use of these measures enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business.

Tangible shareholders’ equity is shareholders’ equity less goodwill and other intangible assets. See reconciliation of Non-GAAP Financial Measures on page 28 in the financial supplement.

These measures should not be viewed as a substitute for net income determined in accordance with generally accepted accounting principles (GAAP).

⁽³⁾ Calculated using income excluding net realized gains (losses) less perpetual preferred securities divided by average common shareholders' equity for the period. To annualize a quarterly rate, multiply by four.

⁽⁴⁾ Book value per common share is common shareholders’ equity divided by the shares outstanding. Tangible book value per common share is common shareholders’ equity less goodwill and other intangible assets divided by the shares outstanding.
