(in millions, except per share amounts)

(Unaudited)

Evan G. Greenberg, Chairman and Chief Executive Officer of ACE Limited, commented: “ACE had an excellent first quarter and a very good start to the year. After-tax operating income of $777 million was driven by both strong underwriting and investment income results, which generated an operating ROE of 11.2%. Per share book and tangible book value grew 2.4% and 3%, respectively.

“Underwriting results were particularly strong in the quarter, with underwriting income up 7% and a P&C combined ratio of 88.8%. Underwriting income benefited from excellent current accident year underwriting income growth before catastrophe losses of 17% as a result of double-digit growth in earned premium and improved margin.

“Premium revenue growth across the company was exceptionally strong, with total P&C net premiums up 12%, or nearly 14% in constant dollars. In North America, our P&C business grew 11% in the quarter and continued to achieve positive rate increases with overall pricing up in casualty-related lines and down in property-related. Internationally, where our P&C business grew more than 12% in constant dollars, pricing was generally flat. Commercial P&C market conditions globally are stable but growing more competitive. This is not a surprise - we are a disciplined organization and prepared. Given our excellent diversification by product, geography and distribution, many areas of our business have attractive growth prospects, and as a result we are confident in our ability to outperform.”

Regulation G—Non-GAAP Financial Measures

In presenting our results, we 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 and financial condition. However, they should not be viewed as a substitute for measures determined in accordance with generally accepted accounting principles (GAAP).

Adjusted net realized gains (losses), net of tax, includes net realized gains (losses) and net realized gains (losses) recorded in other income (expense) related to unconsolidated subsidiaries, and excludes realized gains and losses from fair value changes on crop derivatives. These derivatives were purchased to provide economic benefit, in a manner similar to reinsurance protection, in the event that a significant decline in commodity pricing will impact underwriting results. We view changes in the fair value of these derivatives as part of the results of our underwriting operations, and therefore realized gains and losses from these derivatives are reclassified to adjusted losses and loss expenses.

Net premiums written on a constant-dollar basis and P&C net premiums written on a constant-dollar basis are financial measures which exclude the impact of foreign exchange. We believe it is useful to evaluate the trends in net premiums written, exclusive of the effect of fluctuations in exchange rates between the U.S. dollar and the currencies in which our international business is transacted, as these exchange rates could fluctuate significantly between periods and distort the analysis of trends. The impact is determined by assuming constant foreign exchange rates between periods by translating prior period results using the same local currency exchange rates as the comparable current period. P&C net premiums written excluding acquisitions on a constant-dollar basis exclude the net premiums written of Fianzas Monterrey and ABA Seguros acquired in 2013 in order to adjust for the distortive effect of acquisitions.

Underwriting income, P&C underwriting income, and Global P&C underwriting income are calculated by subtracting losses and loss expenses, policy benefits, policy acquisition costs and administrative expenses from net premiums earned. P&C underwriting income also includes gains (losses) from fair value changes on crop derivatives. 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 adjusted net realized gains (losses). Current accident year underwriting income excluding catastrophe losses is underwriting income adjusted to exclude catastrophe losses, prior period development (PPD), and gains (losses) from fair value changes on crop derivatives. We believe it is useful to exclude catastrophe losses, as they are not predictable as to timing and amount, and PPD as these unexpected loss developments on historical reserves are not indicative of our current underwriting performance. We believe the use of these measures enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business.

Operating income or income excluding adjusted 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 adjusted net realized gains (losses) and net realized gains (losses) included in other income (expense) related to partially-owned entities because the amount of these gains (losses) is heavily influenced by the availability of market opportunities.

P&C combined ratio excluding catastrophe losses and PPD or current accident year P&C combined ratio excluding catastrophe losses exclude impacts of catastrophe losses and PPD. We believe this measure provides a better evaluation of our core underwriting performance and enhances the understanding of the trends in our property and casualty business that may be obscured by these items.

Global P&C performance metrics comprise consolidated operating results (including corporate) and exclude the operating results of the company’s Life and Insurance – North American Agriculture segments. We believe that these measures are useful and meaningful to investors as they are used by management to assess the company’s global P&C operations which are the most economically similar. We exclude the Insurance – North American Agriculture and Life segments because the results of these businesses do not always correlate with the results of our global P&C operations.

Life net premiums written and deposits collected, excluding life reinsurance, is adjusted to include deposits collected on universal life and investment contracts (life deposits) and exclude results from our life reinsurance business. Life deposits are not reflected as revenues in our consolidated statements of operations in accordance with GAAP. We include life deposits in presenting growth in our Life business because new life deposits are an important component of production and key to our efforts to grow our business. We exclude results associated with life reinsurance as there is no new life reinsurance business currently being written.

Operating return on equity (ROE) or ROE calculated using operating income is an annualized financial measure. The ROE numerator includes income adjusted to exclude adjusted net realized gains (losses), net of tax. The ROE denominator includes the average shareholders’ equity for the period adjusted to exclude unrealized gains (losses) on investments, net of tax. To annualize a quarterly rate, multiply by four. Annualized ROE calculated using operating income is a useful measure as it enhances the understanding of the return on shareholders’ equity by highlighting the underlying profitability relative to shareholders’ equity excluding the effect of unrealized gains and losses on our investments.

Tangible book value per common share is shareholders’ equity less goodwill and other intangible assets divided by the shares outstanding. We believe that goodwill and other intangible assets are not indicative of our underlying insurance results or trends and make book value comparisons to less acquisitive peer companies less meaningful.

See reconciliation of Non-GAAP Financial Measures on pages 20-21 in the Financial Supplement. These measures should not be viewed as a substitute for net income, return on equity, or effective tax rate determined in accordance with GAAP.
