Brian Duperreault, Chairman and Chief Executive Officer of ACE Limited, commented: “This was a good quarter for us by any standard of measurement. We were able to demonstrate the earning power we have been building over the last three years. We benefited from growth in earned premiums, improved underwriting margins and strong positive cash flow. However, low investment yields limited our growth in investment income to 3%, which continues to lag the growth in underwriting income. Our annualized ROE from operations was 16.7%.^{( 3 )} In summary, an excellent start for the current fiscal year.”

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

² Annualized operating return on equity is calculated using net operating income (loss) less mezzanine equity dividend divided by average shareholders’ equity for the period.

³ Diluted book value per share is shareholder’s 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.
