“Chubb had an outstanding fourth quarter and an excellent 2014,” said John D. Finnegan, Chairman, President and Chief Executive Officer. “For the quarter, we produced record quarterly operating income per share of $2.29. Our combined ratio in the quarter of 84.3% was our best combined ratio for any quarter in the past six years, reflecting strong underwriting performance in all of our business units as well as low catastrophe losses. We are also pleased that in the fourth quarter we continued to achieve renewal rate increases while maintaining high retention levels in all of our businesses.

“For the full year 2014,” said Mr. Finnegan, “we generated operating income per share of $7.63 and net income per share of $8.62, both of which were the second-highest of any year in our history. Our excellent results in 2014, and our consistent financial performance over time, demonstrate the successful execution of our business and underwriting strategies. We remain committed to our long-standing strategy of focusing on underwriting discipline and superior claims handling, combined with best-in-class producer relationships, a strong balance sheet and active capital management.”

• A combined ratio of 89% to 90%.

• Catastrophe losses that have an impact of 4 percentage points on the 2015 combined ratio. The impact of each percentage point of catastrophe losses on operating income per share is approximately $0.36.

• A decline of 6% to 8% in property and casualty investment income after taxes, including a 1% negative impact of foreign currency translation.

• Approximately 230 million average diluted shares outstanding.

Definitions of Key Terms

Operating Income:

Operating income, a non-GAAP financial measure, is net income excluding after-tax realized investment gains and losses. Management uses operating income, among other measures, to evaluate its performance because the realization of investment gains and losses in any given period is largely discretionary as to timing and can fluctuate significantly, which could distort the analysis of trends.

Underwriting Income (Loss):

Management evaluates underwriting results separately from investment results. The underwriting operations consist of four separate business units: personal insurance, commercial insurance, specialty insurance and reinsurance assumed. Performance of the business units is measured based on statutory underwriting results. Statutory accounting principles applicable to property and casualty insurance companies differ in certain respects from generally accepted accounting principles (GAAP). Under statutory accounting principles, policy acquisition and other underwriting expenses are recognized immediately, not at the time premiums are earned. Statutory underwriting income (loss) is arrived at by reducing premiums earned by losses and loss expenses incurred and statutory underwriting expenses incurred.

Management uses underwriting results determined in accordance with GAAP, among other measures, to assess the overall performance of the underwriting operations. To convert statutory underwriting results to a GAAP basis, certain policy acquisition expenses are deferred and amortized over the period in which the related premiums are earned. Underwriting income (loss) determined in accordance with GAAP is defined as premiums earned less losses and loss expenses incurred and GAAP underwriting expenses incurred.

Property and Casualty Investment Income After Income Tax:

Management uses property and casualty investment income after income tax, a non-GAAP financial measure, to evaluate its investment results because it reflects the impact of any change in the proportion of tax exempt investment income to total investment income and is therefore more meaningful for analysis purposes than investment income before income tax.

Book Value per Common Share with Available-for-Sale Fixed Maturities at Amortized Cost:

Book value per common share represents the portion of consolidated shareholders’ equity attributable to one share of common stock outstanding as of the balance sheet date. Consolidated shareholders’ equity includes, as part of accumulated other comprehensive income or loss, the after-tax appreciation or depreciation, including unrealized other-than-temporary impairment losses, of the Corporation’s available-for-sale fixed maturities, which are carried at fair value. The appreciation or depreciation of available-for-sale fixed maturities is subject to fluctuation due to changes in interest rates and therefore could distort the analysis of trends. Management believes that book value per common share with available-for-sale fixed maturities at amortized cost, a non-GAAP financial measure, is an important measure of the underlying equity attributable to one share of common stock.

7

Combined Loss and Expense Ratio or Combined Ratio:

The combined loss and expense ratio, expressed as a percentage, is the key measure of underwriting profitability. Management uses the combined loss and expense ratio calculated in accordance with statutory accounting principles applicable to property and casualty insurance companies to evaluate the performance of the underwriting operations. It is the sum of the ratio of losses and loss expenses to premiums earned (loss ratio) and the ratio of statutory underwriting expenses to premiums written (expense ratio) after reducing both premium amounts by dividends to policyholders.

Net Written Premiums Growth (Decrease) Excluding the Impact of Foreign Currency Translation:

Management uses net written premiums growth (decrease) excluding the impact of foreign currency translation, a non-GAAP financial measure, to evaluate the trends in net written premiums, exclusive of the effect of fluctuations in exchange rates between the U.S. dollar and the currencies in which international business is transacted. The impact of foreign currency translation is excluded as exchange rates may fluctuate significantly and the effect of fluctuations could distort the analysis of trends. When excluding the impact of foreign currency translation, management uses the same exchange rate to translate each foreign currency denominated net written premium amount in both periods.

• the impact of legislative, regulatory, judicial and similar developments on companies we insure, particularly with respect to our longer tail lines of business;

• the impact of legislative, regulatory, judicial and similar developments on our business, including those relating to insurance industry reform, terrorism, catastrophes, the financial markets, solvency standards, capital requirements, accounting guidance and taxation;
