Company Expects 2011 Operating Income per Share
In Range of $5.35 to $5.75

     WARREN, New Jersey, January 27, 2011— The Chubb Corporation [NYSE: CB] today reported that net income in the fourth quarter of 2010 was $620 million or $2.02 per share, compared to $695 million or $2.03 per share in the fourth quarter of 2009.

     Average diluted shares outstanding for the fourth quarter were 307.4 million in 2010 and 343.1 million in 2009.

     Operating income, which the company defines as net income excluding after-tax realized investment gains and losses, was $519 million, compared to $569 million in the fourth quarter of 2009. Operating income per share increased 2% to $1.69 from $1.66.

     Net written premiums for the fourth quarter were $2.9 billion, an increase of 3%. Premiums were up 2% in the U.S. and up 5% outside the U.S. (up 4% in local currencies).

     The fourth quarter combined loss and expense ratio was 87.0% in 2010 and 84.7% in 2009. The impact of catastrophes on the combined ratio was 1.4 percentage points in 2010 and negligible in 2009. Excluding the impact of catastrophes, the combined ratio was 85.6% in 2010 and 84.7% in 2009. The expense ratio for the fourth quarter was 30.9% in 2010 and 30.1% in 2009.

     Property and casualty investment income after taxes for the fourth quarter increased 1% to $320 million in 2010 from $317 million in 2009.

     Net income for the fourth quarter of 2010 included net realized investment gains of $155 million before tax ($0.33 per share after-tax). Net income for the fourth quarter of 2009 reflected net realized investment gains of $193 million before tax ($0.37 per share after-tax). Gains in both periods were largely related to the company’s alternative investments.

     During the fourth quarter of 2010, Chubb repurchased 8.1 million shares of its common stock at a total cost of $473 million.

     Book value per share was $52.24 at December 31, 2010 compared to $52.41 at the end of the third quarter.

Full Year Results

     For the year ended December 31, 2010, net income was $2.2 billion or $6.76 per share, compared to $2.2 billion or $6.18 per share for the year ended December 31, 2009. Operating income totaled $1.9 billion in 2010 and $2.2 billion in 2009. Operating income per share was $5.90 in 2010 and $6.14 in 2009.

     Average diluted shares outstanding were 321.6 million in 2010 and 353.0 million in 2009.

     Total net written premiums in 2010 increased 1% to $11.2 billion from $11.1 billion in 2009; excluding the effect of currency fluctuation, premiums were flat. Premiums were down 1% in the U.S. and up 9% outside the U.S. (up 3% in local currencies).

     The combined ratio in 2010 was 89.3%, compared to 86.0% in 2009. The impact of catastrophes accounted for 5.7 percentage points of the combined ratio in 2010 and 0.8 points in 2009. Excluding the impact of catastrophes, the combined ratio was 83.6% in 2010 and 85.2% in 2009. The expense ratio for the year was 31.2% in 2010 and 30.6% in 2009.

     Property and casualty investment income after taxes increased 1% to $1.3 billion.

     Net income for 2010 included net realized investment gains of $426 million before tax ($0.86 per share after-tax). Net income for 2009 reflected net realized investment gains of $23 million before tax ($0.04 per share after-tax).

     During 2010, Chubb repurchased 37.7 million shares of its common stock at a total cost of $2.0 billion.

     Book value per share increased 11% to $52.24 at December 31, 2010 from $47.09 at 2009 year end.

     “Chubb’s excellent results in both the fourth quarter of 2010 and the full year continue to demonstrate our ability to generate superior financial results, even in a challenging economic and industry environment,” said John D. Finnegan, Chairman, President and Chief Executive Officer. “Particularly noteworthy were combined ratios that were below 90% in both periods and $1.9 billion of operating income in 2010.

     “Our long-standing strategy of focusing on underwriting discipline combined with best-in-class producer relationships, a strong balance sheet and a conservative investment philosophy have enabled us to generate a very attractive average annual return on equity of 16% over the past five years,” said Mr. Finnegan. “During this same period, we have also returned more than $10 billion of capital to our shareholders through share repurchases and dividends. Our objective is to continue to deliver top-tier results in the future, regardless of the market environment. We believe that Chubb’s unique franchise and our track record of successful execution will enable us to achieve this goal.”

January 2011 Floods in Australia

     Chubb’s first quarter 2011 catastrophe losses will be impacted by flooding in Australia that has occurred in January, particularly in and around the city of Brisbane. Although it is still early in the loss estimation process and available information currently is limited, Chubb’s preliminary estimate of the losses from this flooding is in the range of $75 million to $100 million before tax.

2011 Operating Income Guidance

     Mr. Finnegan said that based on management’s current outlook, he expected Chubb to achieve 2011 operating income per share in the range of $5.35 to $5.75.

     The operating income guidance for 2011 assumes:

	•		Net written premiums that are flat to up 2%.
	•		Catastrophe losses that have an impact of 3.5 percentage points on the 2011 combined ratio, compared to 5.7 points of impact in 2010. The assumed impact of catastrophe losses in 2011 is based on Chubb’s long-term average annual catastrophe losses of 3 percentage points adjusted upward by 0.5 percentage points to take into account anticipated higher than usual catastrophe losses in the first quarter of 2011 resulting largely from the January floods in Australia.  The impact of each percentage point of catastrophe losses on 2011 operating income per share is approximately $0.25.
	•		A combined ratio between 91% and 93% for the year, based on combined ratios of 91% to 94% for CPI, 94% to 97% for CCI and 85% to 88% for CSI.
	•		A decline of 2% to 4% in property and casualty investment income after taxes.
	•		Approximately 291 million average diluted shares outstanding for the year.

     The guidance and related assumptions are subject to the risks outlined in the company’s forward-looking information safe-harbor statements (see below).

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, 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 performance because it reflects the impact of any change in the proportion of the investment portfolio invested in tax exempt securities 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 (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.

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) plus 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 Currency Fluctuation: Management uses net written premiums growth (decrease) excluding the impact of currency fluctuation, 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 our international business is transacted. In net written premiums growth (decrease) excluding the impact of currency fluctuation, the effect of fluctuations in the exchange rates is excluded as these rates may fluctuate significantly and could distort the analysis of trends. Net written premiums growth (decrease) excluding the impact of currency fluctuation is determined by using the same exchange rate to translate each foreign currency denominated net written premium amount in both periods.
