     WARREN, New Jersey, October 26, 2004 — The Chubb Corporation [NYSE: CB] today reported that net income in the third quarter of 2004 was $364.0 million or $1.88 per share, compared to $259.8 million ($1.37 per share) in the third quarter of 2003.

     Operating income, which the company defines as net income excluding after-tax realized investment gains and losses, increased to $332.3 million from $220.5 million in the third quarter of 2003. Operating income per share increased 48% to $1.72 from $1.16.

     The combined loss and expense ratio for the third quarter was 93.3% in 2004 and 96.6% in 2003. Including $180 million in hurricane losses, catastrophe losses in the 2004 third quarter were $196.1 million, accounting for 6.7 percentage points of the combined ratio, compared to $96.0 million (3.7 points) in the third quarter of 2003. The expense ratio for the third quarter was 29.4% in 2004 and 30.9% in 2003.

Nine Month Results

     For the first nine months of 2004, net income was $1.08 billion or $5.61 per share, compared with $736.5 million or $4.13 per share for the first nine months of 2003. Operating income totaled a record $981.4 million or $5.10 per share for the first nine months of 2004, compared with $680.8 million or $3.82 per share in the first nine months of 2003. Results for the first nine months include an after-tax loss of $11 million or $0.06 per share from Chubb Financial Solutions, compared with a loss of $20 million or $0.11 per share in the first nine months of 2003.

     Property and casualty net premiums written in the first nine months of 2004 increased 10% to $9.0 billion. Chubb Re accounted for 1 percentage point of this growth. The combined ratio for the first nine months was 92.9% in 2004 and 95.8% in 2003. Catastrophe losses for the first nine months (excluding the $80 million September 11th reserve release in the second quarter of 2004) were $338.5 million (3.9 percentage points of the combined ratio) in 2004, compared to $261.5 million (3.5 points) in 2003. The expense ratio for the first nine months was 29.7% in 2004 and 30.7% in 2003.

Outlook for 2004

     “Chubb had a terrific third quarter despite the severe hurricane season,” said John D. Finnegan, Chairman, President and Chief Executive Officer, “with solid premium growth, excellent underwriting profitability and higher investment income. Going forward, we are continuing to execute our underwriting strategy, control expenses and focus on selectively growing the business in areas that offer the best profit opportunities.

     “Each quarter this year has been outstanding, resulting in record earnings for the first nine months,” said Mr. Finnegan. “Based on these results and our expectations for the fourth quarter, we are confident that we will achieve our full-year earnings guidance of $6.80 to $7.20 per share. Consistent with our previous guidance, this estimate excludes realized investment gains and losses, excludes Chubb Financial Solutions results and assumes 3 percentage points of catastrophe losses for the year.”

Third Quarter Operations Review

     Chubb Personal Insurance (CPI) premiums grew 9% to $754 million. CPI’s combined ratio was 101.2%, compared to 99.9% in the third quarter of 2003. Catastrophe losses in the third quarter accounted for 19.0 percentage points of the combined ratio in 2004 compared to 10.7 percentage points in 2003. Excluding catastrophe losses, CPI’s combined ratio improved 7.0 points to 82.2% from 89.2%.

     The homeowners line grew 10%, and the combined ratio was 109.1%, which included 32.1 percentage points of catastrophe losses. Excluding catastrophe losses, the combined ratio was 77.0%. Personal automobile insurance grew 6% and had a combined ratio of 92.5%, while other personal lines, which include valuable articles, excess liability and yacht insurance, grew 12% and had a combined ratio of 88.0%.

     Chubb Commercial Insurance (CCI) premiums grew 10% to $1.12 billion. The combined ratio improved to 82.3% from 90.6%. Third quarter catastrophe losses accounted for 3.5 percentage points of the combined ratio in 2004, compared to 2.9 points in 2003.

     Average renewal rates in the U.S. increased 2% for CCI, which retained 85% of the U.S. accounts that came up for renewal. In the U.S., premiums from new accounts exceeded lost business by a 1.4-to-1 margin.

     Chubb Specialty Insurance (CSI) premiums grew 2% to $1.15 billion. The combined ratio was 99.2%, compared to 100.6% in the third quarter of 2003.

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 three separate business units: personal insurance, commercial insurance and specialty insurance. Performance of the business units is based on statutory underwriting results. Statutory accounting principles 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 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, the after-tax appreciation or depreciation on the Corporation’s available-for-sale fixed maturities, which are carried at market value. The appreciation or depreciation on 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 Ratio or Combined Loss and Expense 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.

FORWARD-LOOKING INFORMATION

     Certain statements in this document, and certain oral statements made by management from time to time, are “forward-looking statements” as that term is defined in the Private Securities Litigation Reform Act of 1995 (PSLRA).

Forward-looking statements are made based upon management’s current expectations and beliefs concerning trends and future developments and their potential effects on us. These statements are not guarantees of future performance. Actual results may differ materially from those suggested by forward-looking statements as a result of risks and uncertainties, which include, among others, those discussed or identified from time to time in our public filings with the Securities and Exchange Commission and those associated with:

• the effects on the capital markets and the markets for directors and officers and errors and omissions insurance;

• claims and litigation arising out of actual or alleged accounting or other corporate malfeasance by other companies;

• claims and litigation arising out of practices in the financial services industry;

• legislative or regulatory proposals or changes, including the changes in law and regulation implemented under the Sarbanes-Oxley Act of 2002;

• the effects of investigations into market practices in the U.S. property and casualty insurance industry;

• changes in interest rates, market credit spreads and the performance of the financial markets, generally and as they relate to credit risks assumed by our Chubb Financial Solutions unit in particular;

• the effects of inflation;

• changes in domestic and foreign laws, regulations and taxes;

• changes in competition and pricing environments;

• regional or general changes in asset valuations;

• the inability to reinsure certain risks economically;

• changes in the litigation environment;

• general market conditions; and

• our ability to implement management’s strategic plans and initiatives.

     The Corporation assumes no obligation to update any forward-looking information set forth in this document, which speak as of the date hereof.
