The Chubb Corporation (Chubb) was incorporated as a business corporation under the laws of the State of New Jersey in June 1967. Chubb and its subsidiaries are referred to collectively as the Corporation. Chubb is a holding company for a family of property and casualty insurance companies known informally as the Chubb Group of Insurance Companies (the P&C Group). Since 1882, the P&C Group has provided property and casualty insurance to businesses and individuals around the world. According to A.M. Best, the P&C Group is the 12th largest U.S. property and casualty insurance group based on 2002 net written premiums.

Chubb Financial Solutions (CFS) was organized in 2000 to develop and provide customized risk-financing services through both the capital and insurance markets. CFS’s non-insurance business was primarily structured credit derivatives, principally as a counterparty in portfolio credit default swaps. In the second quarter of 2003, the Corporation implemented a plan to exit the credit derivatives business and is running off the financial products portfolio of CFS. Additional information related to CFS’s operations is presented in the Chubb Financial Solutions section of Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A).

At December 31, 2003, the Corporation had total assets of $38.4 billion and shareholders’ equity of $8.5 billion. Revenues, income before income tax and assets for each operating segment for the three years ended December 31, 2003 are included in Note (15) of the Notes to Consolidated Financial Statements. The Corporation employed approximately 12,300 persons worldwide on December 31, 2003.

The Corporation’s principal executive offices are located at 15 Mountain View Road, Warren, New Jersey 07061-1615, and our telephone number is (908) 903-2000.

The Corporation’s internet address is www.chubb.com. The Corporation’s annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act are available free of charge on this website as soon as reasonably practicable after they have been electronically filed with or furnished to the Securities and Exchange Commission. The Corporation’s Corporate Governance Guidelines, charters of certain key committees of its Board of Directors, Restated Certificate of Incorporation, By-Laws, Code of Business Conduct and Code of Ethics for CEO and Senior Financial Officers are also available on the Corporation’s website or by writing to the Corporation’s Corporate Secretary.

The P&C Group is divided into three strategic business units. Chubb Commercial Insurance offers a full range of commercial customer insurance products, including coverage for multiple peril, casualty, workers’ compensation and property and marine. Chubb Commercial Insurance is known for writing niche business, where our expertise can add value for our agents, brokers and policyholders. Chubb Specialty Insurance offers a wide variety of specialized executive protection and professional liability products for privately and publicly owned companies, financial institutions, professional firms and healthcare organizations. Chubb Specialty Insurance also includes our surety and accident businesses, as well as our reinsurance assumed business produced by Chubb Re. Chubb Personal Insurance offers products for individuals with fine homes and possessions who require more coverage choices and higher limits than standard insurance policies.

The P&C Group provides insurance coverages principally in the United States, Canada, Europe, Australia, and parts of Latin America and Asia. Revenues of the P&C Group by geographic area for the three years ended December 31, 2003 are included in Note (15) of the Notes to Consolidated Financial Statements.

The principal members of the P&C Group are Federal Insurance Company (Federal), Pacific Indemnity Company (Pacific Indemnity), Vigilant Insurance Company (Vigilant), Great Northern Insurance Company (Great Northern), Chubb Custom Insurance Company (Chubb Custom), Chubb

National Insurance Company (Chubb National), Chubb Indemnity Insurance Company (Chubb Indemnity), Chubb Insurance Company of New Jersey (Chubb New Jersey), Texas Pacific Indemnity Company, Northwestern Pacific Indemnity Company, Executive Risk Indemnity Inc. (Executive Risk Indemnity), Executive Risk Specialty Insurance Company (Executive Risk Specialty) and Quadrant Indemnity Company (Quadrant) in the United States, as well as Chubb Atlantic Indemnity Ltd. (a Bermuda company), Chubb Insurance Company of Canada, Chubb Insurance Company of Europe, S.A., Chubb Insurance Company of Australia Limited, Chubb Argentina de Seguros, S.A. and Chubb do Brasil Companhia de Seguros.

Federal is the manager of Vigilant, Pacific Indemnity, Great Northern, Chubb National, Chubb Indemnity, Chubb New Jersey, Executive Risk Indemnity, Executive Risk Specialty and Quadrant. Federal also provides certain services to other members of the P&C Group. Acting subject to the supervision and control of the Boards of Directors of the members of the P&C Group, Federal provides day to day executive management and operating personnel and makes available the economy and flexibility inherent in the common operation of a group of insurance companies.

A summary of the P&C Group’s premiums written during the past three years is shown in the following table:

The net premiums written during the last three years for major classes of the P&C Group’s business are included in the Property and Casualty Insurance Results — Underwriting Results section of MD&A.

One or more members of the P&C Group are licensed and transact business in each of the 50 states of the United States, the District of Columbia, Puerto Rico, the Virgin Islands, Canada, Europe, Australia, and parts of Latin America and Asia. In 2003, approximately 82% of the P&C Group’s direct business was produced in the United States, where the P&C Group’s businesses enjoy broad geographic distribution with a particularly strong market presence in the Northeast. The four states accounting for the largest amounts of direct premiums written were New York with 12%, California with 10%, Texas with 6% and New Jersey with 5%. No other state accounted for 5% of such premiums. Approximately 10% of the P&C Group’s direct premiums written was produced in Europe and 4% was produced in Canada.

A frequently used industry measurement of property and casualty insurance underwriting results is the combined loss and expense ratio. The P&C Group uses the combined loss and expense ratio calculated in accordance with statutory accounting principles. This ratio is the sum of the ratio of incurred losses and related loss adjustment expenses to premiums earned (loss ratio) plus the ratio of underwriting expenses to premiums written (expense ratio) after reducing both premium amounts by dividends to policyholders. When the combined ratio is under 100%, underwriting results are generally considered profitable; when the combined ratio is over 100%, underwriting results are generally considered unprofitable. Investment income is not reflected in the combined ratio. The profitability of property and casualty insurance companies depends on the results of both underwriting operations and investments.

The combined loss and expense ratios during the last three years in total and for the major classes of the P&C Group’s business are included in the Property and Casualty Insurance Results — Underwriting Results section of MD&A.

Another frequently used measurement in the property and casualty insurance industry is the ratio of statutory net premiums written to policyholders’ surplus. At December 31, 2003 and 2002, such ratio for the P&C Group was 1.74 and 2.00, respectively.

In the United States and Canada, the P&C Group is represented by approximately 5,000 independent agencies and accepts business on a regular basis from an estimated 1,000 insurance brokers. In most instances, these agencies and brokers also represent other companies that compete with the P&C Group. The P&C Group’s branch and service offices assist these agencies and brokers in producing and servicing the P&C Group’s business. In addition to the administrative offices in Warren and Whitehouse Station, New Jersey, the P&C Group has seven zone offices and branch and service offices throughout the United States and Canada.

The P&C Group’s overseas business is developed by its foreign agencies and brokers through local branch offices of the P&C Group and by its United States and Canadian agencies and brokers. In conducting its overseas business, the P&C Group reduces the risks relating to currency fluctuations by maintaining investments in those foreign currencies in which the P&C Group has loss reserves and other liabilities. Such investments have characteristics similar to liabilities in those currencies. The net asset or liability exposure to the various foreign currencies is regularly reviewed.

Business for the P&C Group is also produced through participation in certain underwriting pools and syndicates. Such pools and syndicates provide underwriting capacity for risks which an individual insurer cannot prudently underwrite because of the magnitude of the risk assumed or which can be more effectively handled by one organization due to the need for specialized loss control and other services.

In accordance with the normal practice of the insurance industry, the P&C Group assumes and cedes reinsurance with other insurers or reinsurers. Reinsurance is ceded to provide greater diversification of risk and to limit the P&C Group’s maximum net loss arising from large risks or from hazards of potential catastrophic events.

Ceded reinsurance contracts do not relieve the P&C Group of its primary obligation to the policyholders. Thus, a credit exposure exists with respect to reinsurance ceded to the extent that any reinsurer is unable to meet the obligations assumed under the reinsurance contracts. The collectibility of reinsurance is subject to the solvency of the reinsurers and other factors. The P&C Group is selective in regard to its reinsurers, placing reinsurance with only those reinsurers with strong balance sheets and superior underwriting ability. The P&C Group monitors the financial strength of its reinsurers on an ongoing basis. As a result, uncollectible amounts have not been significant.

A large portion of the P&C Group’s ceded reinsurance is effected under contracts known as treaties under which all risks meeting prescribed criteria are automatically covered. Most of the P&C Group’s treaty reinsurance arrangements consist of excess of loss and catastrophe contracts with other insurers or reinsurers which protect against a specified part or all of certain types of losses over stipulated amounts arising from any one occurrence or event. In certain circumstances, reinsurance is also effected by negotiation on individual risks. The amount of each risk retained by the P&C Group is subject to maximum limits which vary by line of business and type of coverage. Retention limits are continually reviewed and are revised periodically as the P&C Group’s capacity to underwrite risks changes.

For a further discussion of the cost and availability of reinsurance, see the Property and Casualty Insurance Results — Underwriting Results section of MD&A.

Unpaid Losses and Loss Adjustment Expenses and Related Amounts Recoverable from Reinsurers

Insurance companies are required to establish a liability in their accounts for the ultimate costs (including loss adjustment expenses) of claims that have been reported but not settled and of claims that have been incurred but not reported. Insurance companies are also required to report as assets the portion of such liability that will be recovered from reinsurers.

The process of establishing the liability for unpaid losses and loss adjustment expenses is complex and imprecise as it must take into consideration many variables that are subject to the outcome of future events. As a result, subjective judgments as to our ultimate exposure to losses are an integral component of our loss reserving process.

The P&C Group’s estimates of losses for reported claims are established judgmentally on an individual case basis. Such estimates are based on the P&C Group’s particular experience with the type of risk involved and its knowledge of the circumstances surrounding each individual claim. These estimates are reviewed on a regular basis or as additional facts become known. The reliability of the estimation process is monitored through comparison with ultimate settlements.

The P&C Group’s estimates of losses for unreported claims are principally derived from analyses of historical patterns of the development of paid and reported losses by accident year for each class of business. This process relies on the basic assumption that past experience, adjusted for the effects of current developments and likely trends, is an appropriate basis for predicting future outcomes. For certain classes of business where anticipated loss experience is less predictable because of the small number of claims and/or erratic claim severity patterns, the P&C Group’s estimates are based on both expected and actual reported losses. Salvage and subrogation estimates are developed from patterns of actual recoveries.

The P&C Group’s estimates of unpaid loss adjustment expenses are based on analyses of the relationship of projected ultimate loss adjustment expenses to projected ultimate losses for each class of business. Claim staff has discretion to override these expense formulas where judgment indicates such action is appropriate.

The P&C Group’s estimates of reinsurance recoverable related to reported and unreported losses and loss adjustment expenses represent the portion of such liabilities that will be recovered from reinsurers. Amounts recoverable from reinsurers are recognized as assets at the same time and in a manner consistent with the liabilities associated with the reinsured policies.

Estimates are continually reviewed and updated. Any changes in estimates are reflected in operating results in the period in which the estimates are changed.

The anticipated effect of inflation is implicitly considered when estimating liabilities for unpaid losses and loss adjustment expenses. Estimates of the ultimate value of all unpaid losses are based in part on the development of paid losses, which reflect actual inflation. Inflation is also reflected in the case estimates established on reported open claims which, when combined with paid losses, form another basis to derive estimates of reserves for all unpaid losses. There is no precise method for subsequently evaluating the adequacy of the consideration given to inflation, since claim settlements are affected by many factors.

Additional information related to the P&C Group’s estimates related to unpaid losses and loss adjustment expenses and the uncertainties in the estimation process is presented in the Property and Casualty Insurance Results — Loss Reserves section of MD&A.

The P&C Group continues to emphasize early and accurate reserving, inventory management of claims and suits, and control of the dollar value of settlements. The number of outstanding claims at

The significant uncertainties relating to asbestos and toxic waste claims on insurance policies written many years ago are discussed in the Property and Casualty Insurance Results — Loss Reserves section of MD&A.

One master claim is generally established for all similar asbestos claims and lawsuits involving an insured. A counted claim can have from one to thousands of claimants. Generally, a toxic waste claim is established for each lawsuit, or alleged equivalent, against an insured where potential liability has been determined to exist under a policy issued by a member of the P&C Group. Management does not believe the following claim count data is meaningful for analysis purposes.

There were approximately 800 asbestos claims outstanding at December 31, 2003 compared with 900 asbestos claims outstanding at December 31, 2002 and 1,000 asbestos claims outstanding at December 31, 2001. In 2003, approximately 200 claims were opened and 300 claims were closed. In 2002, approximately 300 claims were opened and 400 claims were closed. In 2001, approximately 200 claims were opened and 300 claims were closed. Indemnity payments per claim have varied over time due primarily to variations in insureds, policy terms and types of claims. Management cannot predict whether indemnity payments per claim will increase, decrease or remain the same.

There were approximately 600 toxic waste claims outstanding at December 31, 2003 and 2002, compared with 650 toxic waste claims outstanding at December 31, 2001. Approximately 300 claims were opened in 2003 and 250 claims were opened in both 2002 and 2001. There were approximately 300 claims closed in both 2003 and 2002, and 250 claims closed in 2001. Because payments to date for toxic waste claims have varied from claim to claim, management cannot determine whether past claims experience will prove to be representative of future claims experience.

The table on page 9 presents the subsequent development of the estimated year-end liability for unpaid losses and loss adjustment expenses, net of reinsurance recoverable, for the ten years prior to 2003. The Corporation acquired Executive Risk Inc. in 1999. The amounts in the table for the years ended December 31, 1993 through 1998 do not include Executive Risk’s unpaid losses and loss adjustment expenses.

The top line of the table shows the estimated net liability for unpaid losses and loss adjustment expenses recorded at the balance sheet date for each of the indicated years. This liability represents the estimated amount of losses and loss adjustment expenses for claims arising in all prior years that are unpaid at the balance sheet date, including losses that had been incurred but not yet reported to the P&C Group.

The upper section of the table shows the reestimated amount of the previously recorded net liability based on experience as of the end of each succeeding year. The estimate is increased or decreased as more information becomes known about the frequency and severity of claims for each individual year. The increase or decrease is reflected in operating results in the year the estimate is changed. The “cumulative deficiency (redundancy)” as shown in the table represents the aggregate change in the reserve estimates from the original balance sheet dates through December 31, 2003. The amounts noted are cumulative in nature; that is, an increase in a loss estimate that is related to a prior period occurrence generates a deficiency in each intermediate year. For example, a deficiency recognized in 2003 relating to losses incurred prior to December 31, 1993 would be included in the cumulative deficiency amount for each year in the period 1993 through 2002. Yet, the deficiency would be reflected in operating results only in 2003. The effect of changes in estimates of the liabilities for losses occurring in prior years on income before income taxes in each of the past three years is shown in the reconciliation of the beginning and ending liability for unpaid losses and loss adjustment expenses in the Property and Casualty Insurance Results — Loss Reserves section of MD&A.

In each of the years 1993 through 2002, there was substantial unfavorable development related to asbestos and toxic waste claims. The cumulative net deficiencies experienced related to asbestos and

toxic waste claims were the result of: (1) an increase in the actual number of claims filed; (2) an increase in the number of potential claims estimated; (3) an increase in the severity of actual and potential claims; (4) an increasingly adverse litigation environment; and (5) an increase in litigation costs associated with such claims. In addition to the unfavorable development related to asbestos and toxic waste claims in 2001 and 2002, there was unfavorable development in the executive protection classes, principally directors and officers liability and errors and omissions liability, due to adverse loss trends related to the corporate failures and allegations of management misconduct and accounting irregularities in recent years. In the years 1993 through 2000, the unfavorable development related to asbestos and toxic waste claims was offset in varying degrees by favorable loss experience for certain executive protection coverages, particularly directors and officers liability and fiduciary liability, and commercial excess liability.

Conditions and trends that have affected development of the liability for unpaid losses and loss adjustment expenses in the past will not necessarily recur in the future. Accordingly, it is not appropriate to extrapolate future redundancies or deficiencies based on the data in this table.

The middle section of the table on page 9 shows the cumulative amount paid with respect to the reestimated liability as of the end of each succeeding year. For example, in the 1993 column, as of December 31, 2003 the P&C Group had paid $5,037.8 million of the currently estimated $6,594.1 million of losses and loss adjustment expenses that were unpaid at the end of 1993; thus, an estimated $1,556.3 million of losses incurred through 1993 remain unpaid as of December 31, 2003, approximately 80% of which relates to asbestos and toxic waste claims.

The lower section of the table on page 9 shows the gross liability, reinsurance recoverable and net liability recorded at each year-end and the reestimation of these amounts as of December 31, 2003.

The liability for unpaid losses and loss adjustment expenses, net of reinsurance recoverable, reported in the accompanying consolidated financial statements prepared in accordance with generally accepted accounting principles (GAAP) comprises the liabilities of U.S. and foreign members of the P&C Group as follows:

Members of the P&C Group are required to file annual statements with insurance regulatory authorities prepared on an accounting basis prescribed or permitted by such authorities (statutory basis). There is no difference between the liability for unpaid losses and loss expenses reported in the statutory basis financial statements of the U.S. members of the P&C Group and such liability reported on a GAAP basis in the consolidated financial statements.

The amounts for the years 1993 through 1998 do not include Executive Risk’s unpaid losses and loss adjustment expenses. Executive Risk was acquired in 1999.

Investment decisions are centrally managed by investment professionals based on guidelines established by management and approved by the respective boards of directors for each member of the P&C Group.

Bellemead Development Corporation and its subsidiaries (Bellemead) are involved in commercial development activities primarily in New Jersey and residential development activities primarily in central Florida. Additional information related to the Corporation’s real estate operations is included in the Corporate and Other — Real Estate section of MD&A.

Chubb is a holding company with subsidiaries primarily engaged in the property and casualty insurance business and is therefore subject to regulation by certain states as an insurance holding company. All states have enacted legislation which regulates insurance holding company systems such as the Corporation. This legislation generally provides that each insurance company in the system is required to register with the department of insurance of its state of domicile and furnish information concerning the operations of companies within the holding company system which may materially affect the operations, management or financial condition of the insurers within the system. All transactions within a holding company system affecting insurers must be fair and equitable. Notice to the insurance commissioners is required prior to the consummation of transactions affecting the ownership or control of an insurer and of certain material transactions between an insurer and any person in its holding company system and, in addition, certain of such transactions cannot be consummated without the commissioners’ prior approval.

The P&C Group is subject to regulation and supervision in the states in which it does business. In general, such regulation is for the protection of policyholders rather than shareholders. The extent of such regulation varies but generally has its source in statutes which delegate regulatory, supervisory and administrative powers to a department of insurance. The regulation, supervision and administration relate to, among other things, the standards of solvency which must be met and maintained; the

licensing of insurers and their agents; restrictions on insurance policy terminations; unfair trade practices; the nature of and limitations on investments; premium rates; restrictions on the size of risks which may be insured under a single policy; deposits of securities for the benefit of policyholders; approval of policy forms; periodic examinations of the affairs of insurance companies; annual and other reports required to be filed on the financial condition of companies or for other purposes; limitations on dividends to policyholders and shareholders; and the adequacy of provisions for unearned premiums, unpaid losses and loss adjustment expenses, both reported and unreported, and other liabilities.

The extent of insurance regulation on business outside the United States varies significantly among the countries in which the P&C Group operates. Some countries have minimal regulatory requirements, while others regulate insurers extensively. Foreign insurers in many countries are subject to greater restrictions than domestic competitors. In certain countries, the P&C Group has incorporated insurance subsidiaries locally to improve its position.

The National Association of Insurance Commissioners has a risk-based capital requirement for property and casualty insurance companies. The risk-based capital formula is used by state regulatory authorities to identify insurance companies which may be undercapitalized and which merit further regulatory attention. The formula prescribes a series of risk measurements to determine a minimum capital amount for an insurance company, based on the profile of the individual company. The ratio of a company’s actual policyholders’ surplus to its minimum capital requirement will determine whether any state regulatory action is required. At December 31, 2003, each member of the P&C Group had more than sufficient capital to meet the risk-based capital requirement.

Regulatory requirements applying to premium rates vary from state to state, but generally provide that rates not be “excessive, inadequate or unfairly discriminatory.” Rates for many lines of business, including automobile and homeowners insurance, are subject to prior regulatory approval in many states. However, in certain states, prior regulatory approval of rates is not required for most lines of insurance which the P&C Group underwrites. Ocean marine insurance rates are exempt from regulation.

Subject to regulatory requirements, the P&C Group’s management determines the prices charged for its policies based on a variety of factors including loss and loss adjustment expense experience, inflation, tax law and rate changes, and anticipated changes in the legal environment, both judicial and legislative. Methods for arriving at prices vary by type of business, exposure assumed and size of risk. Underwriting profitability is affected by the accuracy of these assumptions, by the willingness of insurance regulators to approve changes in those rates which they control and by such other matters as underwriting selectivity and expense control.

The property and casualty insurance industry is highly competitive both as to price and service. Members of the P&C Group compete not only with other stock companies but also with mutual companies, other underwriting organizations and alternative risk sharing mechanisms. Some competitors obtain their business at a lower cost through the use of salaried personnel rather than independent agents and brokers. Rates are not uniform for all insurers and vary according to the types of insurers and methods of operation. The P&C Group competes for business not only on the basis of price, but also on the basis of availability of coverage desired by customers and quality of service, including claim adjustment service. The P&C Group’s products and services are generally designed to serve specific customer groups or needs and to offer a degree of customization that is of value to the insured. The P&C Group continues to work closely with its customers and to reinforce with them the stability, expertise and added value the P&C Group provides.

There are approximately 3,300 property and casualty insurance companies in the United States operating independently or in groups and no single company or group is dominant. The relatively large size and underwriting capacity of the P&C Group provide opportunities not available to smaller companies.

In all states, insurers authorized to transact certain classes of property and casualty insurance are required to become members of an insolvency fund. In the event of the insolvency of a licensed insurer writing a class of insurance covered by the fund in the state, members are assessed to pay certain claims against the insolvent insurer. Generally, fund assessments are proportionately based on the members’ written premiums for the classes of insurance written by the insolvent insurer. In certain states, a portion of these assessments is recovered through premium tax offsets and policyholder surcharges. In 2003, assessments to the members of the P&C Group amounted to $11 million. The amount of future assessments cannot be reasonably estimated.

State insurance regulation requires insurers to participate in assigned risk plans, reinsurance facilities and joint underwriting associations, which are mechanisms that generally provide applicants with various basic insurance coverages when they are not available in voluntary markets. Such mechanisms are most prevalent for automobile and workers’ compensation insurance, but a majority of states also mandate participation in Fair Plans or Windstorm Plans, which provide basic property coverages. Some states also require insurers to participate in facilities that provide homeowners, crime and other classes of insurance where periodic market constrictions may occur. Participation is based upon the amount of a company’s voluntary written premiums in a particular state for the classes of insurance involved. These involuntary market plans generally are underpriced and produce unprofitable underwriting results.

In several states, insurers, including members of the P&C Group, participate in market assistance plans. Typically, a market assistance plan is voluntary, of limited duration and operates under the supervision of the insurance commissioner to provide assistance to applicants unable to obtain commercial and personal liability and property insurance. The assistance may range from identifying sources where coverage may be obtained to pooling of risks among the participating insurers.

Although the federal government and its regulatory agencies generally do not directly regulate the business of insurance, federal initiatives often have an impact on the business in a variety of ways. Current and proposed federal measures which may significantly affect the insurance business include federal terrorism insurance, asbestos liability reform measures, tort reform, corporate governance including the expansion of the Securities and Exchange Commission’s oversight authority over public companies and public accounting firms, ergonomics, health care reform including the containment of medical costs, medical malpractice reform and patients’ rights, privacy, e-commerce, international trade, federal regulation of insurance companies and the taxation of insurance companies.

Insurance companies are also affected by a variety of state and federal legislative and regulatory measures as well as by decisions of their courts that define and extend the risks and benefits for which insurance is provided. These include redefinitions of risk exposure in areas such as water damage, including mold; products liability and commercial general liability; extension and protection of employee benefits, including workers’ compensation and disability benefits; and credit scoring.

Legislative and judicial developments pertaining to asbestos and toxic waste exposures are discussed in the Property and Casualty Insurance Results — Loss Reserves section of MD&A.

The executive offices of the Corporation are in Warren, New Jersey. The administrative offices of the P&C Group are in Warren and Whitehouse Station, New Jersey. The P&C Group maintains zone administrative and branch offices in major cities throughout the United States and also has offices in Canada, Europe, Australia, Latin America and Asia. Office facilities are leased with the exception of buildings in Whitehouse Station and Branchburg, New Jersey and Simsbury, Connecticut. Management considers its office facilities suitable and adequate for the current level of operations.

As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2002, a purported class action complaint was filed in the United States District Court for the District of New Jersey on August 31, 2000 by the California Public Employees’ Retirement System. The complaint alleges that the Corporation and one current officer, Henry B. Schram, and two former officers, Dean R. O’Hare and David B. Kelso, and Executive Risk Inc. and three of its former officers, Stephen J. Sills, Robert H. Kullas and Robert V. Deutsch, are liable for certain misrepresentations and omissions regarding, among other matters, disclosures made between April 27, 1999 and October 15, 1999 relating to the improved pricing in the Corporation’s standard commercial insurance business and relating to the offer of the Corporation’s securities to, and solicitation of votes from, the former shareholders of Executive Risk Inc. in connection with the Corporation’s acquisition of Executive Risk Inc. On August 11, 2003, the trial court dismissed the entire action with prejudice. On September 10, 2003, the plaintiffs filed a Notice of Appeal to the United States Court of Appeals for The Third Circuit. The Corporation is defending the action vigorously.

As previously disclosed, beginning in December 2002, Chubb Indemnity was served with a number of complaints related to a series of actions commenced by various plaintiffs against Chubb Indemnity and other non-affiliated insurers in the District Courts of Nueces and Bexar Counties in Texas. As of December 31, 2003, Chubb Indemnity has been served with a total of thirty-nine complaints in Texas. Since July 2003, the trial court has ordered dismissal of fifteen of the Nueces County cases and five Nueces County cases have been voluntarily dismissed by plaintiffs. Also, beginning in June 2003, Chubb Indemnity was served with similar cases in Cuyahoga County, Ohio. As of December 31, 2003, Chubb Indemnity has been served in eleven cases in Ohio. The allegations and the damages sought in the Ohio actions are substantially similar to those in the Texas actions. Chubb Indemnity is vigorously defending all of these actions.

Information regarding certain litigation to which the P&C Group is a party is included in the Property and Casualty Insurance Results — Loss Reserves section of MD&A.

Chubb and its subsidiaries are also defendants in various lawsuits arising out of their businesses. It is the opinion of management that the final outcome of these matters will not materially affect the consolidated financial position of the registrant.

No matters were submitted to a vote of the shareholders during the last quarter of the year ended December 31, 2003.

All of the foregoing officers serve at the pleasure of the Board of Directors of the Corporation and have been employees of the Corporation for more than five years except for Mr. Finnegan and Ms. Bober.

Before joining the Corporation in 2002, Mr. Finnegan was Executive Vice President of General Motors Corporation and Chairman, President and Chief Executive Officer of General Motors Acceptance Corporation (GMAC). Previously, he had also served as President, Vice President and Group Executive of GMAC.

Prior to joining the Corporation in 1999, Ms. Bober was Senior Vice President, General Counsel and Secretary of General Signal Corporation since 1997. Previously, she was a partner in the law firm of Jones, Day, Reavis & Pogue.

Item 5. Market for the Registrant’s Common Stock and Related Security Holder Matters

The common stock of the Corporation is listed and principally traded on the New York Stock Exchange (NYSE) under the trading symbol “CB”. The following are the high and low closing sale prices as reported on the NYSE Composite Tape and the quarterly dividends declared per share for each quarter of 2003 and 2002.

At February 27, 2004, there were approximately 5,800 common shareholders of record.

The declaration and payment of future dividends to the Corporation’s shareholders will be at the discretion of the Corporation’s Board of Directors and will depend upon many factors, including the Corporation’s operating results, financial condition and capital requirements, and the impact of regulatory constraints discussed in Note (20)(f) of the Notes to Consolidated Financial Statements.

Underwriting income in 2002 and 2003 has been increased by reductions in net surety bond losses related to Enron of $88.0 million ($57.2 million after-tax or $0.33 per share) and $17.0 million ($11.1 million after-tax or $0.06 per share), respectively.


(c)	Underwriting income has been reduced by net costs of $635.0 million and other charges included costs of $10.0 million (in the aggregate, $420.0 million after-tax or $2.39 per share) related to the September 11 attack.


(d)	Federal and foreign income tax in 2002 included a $40.0 million ($0.23 per share) charge to establish a tax valuation allowance from not being able to recognize, for accounting purposes, certain U.S. tax benefits related to European losses. Federal and foreign income tax in 2003 included a $40.0 million ($0.22 per share) credit for the reversal of the tax valuation allowance established in 2002.


(e)	Amounts in years prior to 2003 have been restated to reflect the accounting changes prescribed by Financial Accounting Standards Board Interpretation No. 46, Consolidation of Variable Interest Entities, an interpretation of Accounting Research Bulletin No. 51.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s discussion and analysis of financial condition and results of operations addresses the financial condition of The Chubb Corporation and its subsidiaries as of December 31, 2003 compared with December 31, 2002 and the results of operations for each of the three years in the period ended December 31, 2003. This discussion should be read in conjunction with the consolidated financial statements and related notes and the other information contained in this report.

The consolidated financial statements include amounts based on informed estimates and judgments of management for those transactions that are not yet complete. Such estimates and judgments affect the reported amounts in the financial statements. Those estimates and judgments that were most critical to the preparation of the financial statements involved the adequacy of loss reserves and the recoverability of related reinsurance recoverables, the fair value of future obligations under financial products contracts and the recoverability of the carrying value of real estate properties. These estimates and judgments, which are discussed within the following analysis of our results of operations, require the use of assumptions about matters that are highly uncertain and therefore are subject to change as facts and circumstances develop. If different estimates and judgments had been applied, materially different amounts might have been reported in the financial statements.

The following highlights do not address all of the matters covered in the other sections of Management’s Discussion and Analysis of Financial Condition and Results of Operations or contain all of the information that may be important to the Corporation’s shareholders or the investing public. This


	•	Net income was $809 million in 2003 compared with $223 million in 2002 and $112 million in 2001.

	•	The fundamentals of our property and casualty insurance business are strong. Premium growth was 22% in 2003 and 30% in 2002. Rate increases have been substantial in recent years, often with more favorable policy terms and conditions.

	•	Our underwriting results in the past three years were adversely affected by losses related to asbestos and toxic waste claims, the September 11, 2001 attack in the United States and surety losses arising from the bankruptcy of Enron Corp.


	•	Asbestos and toxic waste losses were $250 million in 2003, $741 million in 2002 and $61 million in 2001.

	•	Results in 2001 were adversely affected by net costs of $645 million related to the September 11 attack.

	•	Results in 2001 were adversely affected by net surety losses of $220 million related to Enron. Results in 2002 and 2003 benefited from reductions in net surety losses related to Enron of $88 million and $17 million, respectively.


	•	Our combined loss and expense ratio, as adjusted to exclude the effects of asbestos and toxic waste losses, the September 11 attack and the Enron surety losses and related benefits, was 95.7% in 2003 compared with 98.6% in 2002 and 99.6% in 2001.

	•	During 2003, we experienced overall unfavorable development of $397 million on loss reserves established as of the previous year end, due primarily to two factors.


	•	We strengthened asbestos loss reserves by $250 million in the fourth quarter.

	•	We experienced unfavorable development of about $140 million in our executive protection classes, principally directors and officers liability and errors and omissions liability, as adverse loss trends in recent accident years related to corporate failures and allegations of management misconduct and accounting irregularities more than offset favorable loss experience in older accident years.


	•	Property and casualty investment income after taxes increased by 11% in 2003 compared with growth of 2% in 2002.

	•	The non-insurance business of Chubb Financial Solutions (CFS) produced a loss before taxes of $127 million in 2003 compared with a loss of $70 million in 2002 and income of $9 million in 2001. As announced in April 2003, we are exiting this business and are running off the financial products portfolio of CFS. We reduced our aggregate notional exposure by $14 billion during 2003 to approximately $25 billion at year end.

	•	Because of substantially improved results in Chubb Europe throughout 2003, we eliminated a $40 million tax valuation allowance in the fourth quarter that was established in the fourth quarter of 2002.

	•	We began expensing the cost of stock options in 2003, which resulted in a reduction in net income of $46 million.

Net income included realized investment gains after taxes of $55 million in 2003, $22 million in 2002 and $1 million in 2001. Decisions to sell securities are governed principally by considerations of investment opportunities and tax consequences. As a result, realized gains and losses on the sale of investments may vary significantly from period to period.

Our property and casualty business produced income before taxes of $1,133 million in 2003 compared with income of $278 million in 2002 and a loss of $53 million in 2001.

Asbestos and toxic waste losses, costs related to the September 11 attack and Enron-related surety losses and related benefits are significant components in understanding and assessing our financial performance. However, these items, which are discussed below, had a distorting effect on our results.

As adjusted, property and casualty earnings in 2003 were significantly higher than in the prior two years due primarily to a substantial improvement in underwriting results. Earnings in 2003 also benefited from a significant increase in investment income.

The profitability of the property and casualty insurance business depends on the results of both underwriting operations and investments, which we view as two distinctive operations. The underwriting functions are managed separately from the investment function. Accordingly, in assessing our performance, we evaluate underwriting results separately from investment results.

We evaluate the underwriting results of our property and casualty insurance business in the aggregate and also for each of our three separate business units: personal insurance, commercial insurance and specialty insurance.

The combined loss and expense ratio, expressed as a percentage, is the key measure of underwriting profitability traditionally used in the property and casualty business. We evaluate the performance of our underwriting operations and of each of our business units using the combined loss and expense ratio calculated in accordance with statutory accounting principles. It is the sum of the ratio of losses to premiums earned (loss ratio) plus the ratio of underwriting expenses to premiums written (expense ratio) after reducing both premium amounts by dividends to policyholders. When the combined ratio is under 100%, underwriting results are generally considered profitable; when the combined ratio is over 100%, underwriting results are generally considered unprofitable.

Statutory accounting principles differ in certain respects from generally accepted accounting principles (GAAP). Under statutory accounting principles applicable to property and casualty insurance companies, policy acquisition and other underwriting expenses are recognized immediately, not at the time premiums are earned. We use underwriting results determined in accordance with GAAP, among other measures, to assess the overall performance of the underwriting operations. To convert 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 incurred and GAAP underwriting expenses incurred.

Net premiums written amounted to $11.1 billion in 2003, an increase of 22% over 2002. Net premiums written increased 30% in 2002 compared with 2001. Premiums written in 2001 included net reinsurance reinstatement premium revenue of $30 million related to the September 11 attack.

About 80% of our net premiums written are in the United States. Premium growth in the U.S. was 22% in 2003 and 31% in 2002. Substantial premium growth was also achieved outside the United States in 2003 and 2002. Reported non-U.S. premiums grew 25% in 2003 and 27% in 2002. In local currencies, such premiums grew 15% and 24% in 2003 and 2002, respectively.

Premium growth in 2002 and 2003 in all segments of our business was due primarily to higher rates. Premium growth was particularly strong in the commercial and specialty classes. Premium growth in our other specialty insurance business was primarily from Chubb Re, our reinsurance business that began operations in 1999.

In the wake of heavy insurance industry losses in recent years, exacerbated by the tragic event of September 11, 2001, many insurance companies sought substantial price increases, raised deductibles, reduced coverage limits or declined outright to renew coverage. In this environment, we have taken advantage of the opportunities to write new business and have retained more of our existing accounts. During 2002, we experienced substantial rate increases on business we wrote, often with more favorable policy terms and conditions. In 2003, we continued to get rate increases on much of the business we wrote, although the size of such increases decelerated throughout the year. We expect that rate increases will continue into 2004, although the size of rate increases will continue to decelerate.

Our premiums written are net of amounts ceded to reinsurers who assume a portion of the risk under the insurance policies that are subject to the reinsurance. As a result of the substantial losses incurred by reinsurers in recent years, the cost of reinsurance in the marketplace has increased significantly and reinsurance capacity for certain coverages, such as terrorism, is limited and expensive.

In 2002, we did not renew a workers’ compensation catastrophe treaty that had substantially reduced our net losses from the September 11 attack because the terms and price that were offered were uneconomical.

Our property reinsurance program renews each April. The 2002 renewal of the property per risk treaty and property catastrophe treaties in the aggregate cost approximately $120 million more on an

annualized basis, with more restrictive terms, including terrorism exclusions. Our property per risk retention increased from $10 million to $15 million. Our catastrophe treaty for events in the United States was modified to increase our initial retention, to increase the reinsurance coverage at the top and to reduce our participation in certain layers of the program.

Our 2003 reinsurance program was similar to that in 2002. Reinsurance costs increased in line with the higher premiums on the policies reinsured. We discontinued some lower limit treaties that we believed were no longer economical and increased our participation in certain layers of the treaties renewed. Our property catastrophe treaty for events in the United States was again modified in 2003 to increase the reinsurance coverage at the top due to our increased exposure in certain catastrophe exposed areas. The program now provides coverage for individual catastrophe events of approximately 86% of losses between $150 million and $850 million, with additional coverage above $850 million that varies depending on geographic location.

It is expected that reinsurance costs will increase in 2004 in line with the higher premiums on the policies reinsured. In January 2004, we discontinued a casualty per risk treaty that responded primarily to excess liability exposures over $25 million, due to a reduction in the number of such exposures that we believed made this treaty no longer economical. Our executive protection per risk treaty was renewed on terms similar to the prior year, except our initial deductible on directors and officers liability losses was increased.

Underwriting results in 2003, 2002 and 2001 were adversely affected by incurred losses of $250 million, $741 million and $61 million, respectively, related to asbestos and toxic waste claims. Underwriting results in 2001 were adversely affected by net costs of $635 million related to the September 11 attack and Enron related surety losses of $220 million. Results in 2002 and 2003 benefited from reductions in surety losses related to Enron of $88 million and $17 million, respectively.

The combined loss and expense ratio, as reported and as adjusted to exclude the effects of the asbestos and toxic waste losses, the September 11 attack and the Enron surety losses and related benefits, was as follows:

The loss ratio, as adjusted, improved in 2003 despite higher catastrophe losses, reflecting the favorable experience resulting from our disciplined underwriting standards in recent years. Losses from catastrophes other than the September 11 attack were $294 million in 2003 which represented 2.9 percentage points of the loss ratio compared with $98 million or 1.2 percentage points in 2002 and $114 million or 1.7 percentage points in 2001. Other than reinsurance recoveries related to the September 11 attack, we did not have any recoveries from our catastrophe reinsurance program during the three year period since there were no other individual catastrophes for which our losses exceeded the initial retention. Our initial retention level for each catastrophic event in the United States was

Our expense ratio decreased in 2002 and again in 2003 due in large part to premiums written growing at a substantially higher rate than overhead expenses. The improvement in 2003 was achieved despite an approximate 0.4 of a percentage point adverse impact of expensing stock options.

Asbestos and Toxic Waste Losses. In October 2002, our actuaries and claim personnel together with our outside actuarial consultants completed their periodic ground-up exposure based analysis of our asbestos related liabilities. Upon completion of the analysis and assessment of the results, we increased our net loss reserves by $625 million in the third quarter. In the fourth quarter of 2002, we reduced our previous estimate of reinsurance recoverable on potential asbestos claims, resulting in an additional increase in our net loss reserves of $75 million. Prior to the completion of the analysis, we had incurred asbestos and toxic waste net losses of $41 million in the first half of 2002 and $61 million during all of 2001.

In the fourth quarter of 2003, our actuaries and claim personnel together with our outside actuarial consultants performed a rigorous update of the 2002 ground-up analysis of our asbestos related liabilities. Upon completion of the update, we increased our net loss reserves by an additional $250 million. Our asbestos and toxic waste exposure is further discussed under “Loss Reserves.”

Enron-Related Surety Losses. Our surety losses arising from the Enron bankruptcy relate to bonds issued to various obligees in connection with Enron commitments. Although certain of these surety bonds were the subject of litigation, we recognized our maximum exposure of $220 million, net of reinsurance, in the fourth quarter of 2001. As of the end of 2002, the litigation was settled, resulting in an $88 million reduction in our surety net loss reserves. Results in 2003 benefited from a $17 million recovery from the sale of a bankruptcy claim against various Enron entities.

September 11 Attack. The pre-tax costs of $645 million related to the September 11 attack had three components. First, in our insurance business, we incurred estimated net losses and loss expenses of $555 million plus reinsurance reinstatement costs of $50 million, for an aggregate cost of $605 million. Each of our underwriting segments was affected by the September 11 attack. However, the impact was by far the greatest on our financial institutions business. Second, in our reinsurance business written through Chubb Re, we incurred estimated net losses and loss expenses of $110 million and recognized reinstatement premium revenue of $80 million, for a net cost of $30 million. Finally, we recorded a $10 million charge, included in other charges, as our share of the losses publicly estimated by Hiscox plc, a U.K. insurer in which we had a 28% interest during 2001.

We estimate that our gross losses and loss expenses from the September 11 attack were about $3.2 billion. Most of the losses were from property exposure and business interruption losses. We also had significant workers’ compensation losses. Our net losses and loss expenses of $665 million were significantly lower than the gross amount due to various reinsurance agreements. Our property exposures were protected by facultative reinsurance, property per risk treaties that limited our net loss per risk, and our property catastrophe treaties. Our workers’ compensation losses were protected by a casualty catastrophe treaty and a casualty “clash” treaty that operates like a catastrophe treaty.

Certain of our reinsurers questioned our interpretation and/or application of some provisions of our property per risk reinsurance agreements with regard to the September 11 losses. The questions raised generally involved the applicable limit of reinsurance coverage available to us, the definition of what constitutes one risk, our accumulation of exposure in the various buildings destroyed or damaged and our adherence to our underwriting guidelines. During 2003, we resolved all of the questions that had been raised by our property per risk reinsurers. That resolution will result in our collecting an amount of reinsurance that confirms our estimate of net costs of $645 million related to the September 11 attack.

It is possible that our estimate of ultimate losses related to the September 11 attack may change in the future, and that the change in estimate could have a material effect on the Corporation’s results of

Net premiums from personal insurance, which represent 23% of the premiums written by our property and casualty subsidiaries, increased by 12% in 2003 compared with a 17% increase in 2002. In both years, premium growth occurred in all classes. Premium growth was particularly significant in our homeowners business due primarily to higher rates and increased insurance-to-value. Homeowners premiums were up 14% and 22% in 2003 and 2002, respectively, while the in-force policy count remained flat in 2003 after being up slightly in 2002.

Our personal insurance business produced modestly profitable underwriting results in 2003 and 2002 compared with slightly unprofitable results in 2001. Results in 2001 included net costs of $20 million related to the September 11 attack. The combined loss and expense ratios for the classes of business within the personal insurance segment, as reported and as adjusted to exclude the effects of the September 11 attack, were as follows:

Homeowners results were similarly unprofitable in 2003 and 2002 as higher catastrophe losses in 2003 were offset by a decrease in non-catastrophe losses and the impact of improved pricing. Results in 2003 benefited from a decline in fire and water damage losses. Results improved in 2002 compared with 2001. The improvement in 2002 was due to a decrease in the frequency of both catastrophe and non-catastrophe losses. Results in 2002 and 2001 were adversely affected by an increase in the severity of water damage claims, including those related to mold, particularly in Texas. Losses from catastrophes other than the September 11 attack represented 13.4 percentage points of the loss ratio for this class in 2003 compared with 2.9 percentage points in 2002 and 5.4 percentage points in 2001. Homeowners results were modestly profitable in Europe in 2003 compared with unprofitable results in 2002 and 2001. We are in the process of exiting our personal lines business in Continental Europe, with the exception of the ultra high net worth market segment.

Our remediation plan relating to our homeowners business in the United States, which began in the latter part of 2001, is on track. We have made substantial progress in implementing rate increases in states where rates have been deficient. While the impact of losses related to water damage, including mold, decreased in 2003 compared with the prior two years, we remain concerned about the potential for such claims. We have made regulatory filings in most states to introduce contract changes that would enable us to treat mold as a separate peril available at an appropriate price. These changes have been implemented in 41 states, including Texas, California, Florida and New York, and approved in four other states.

Our personal automobile business was modestly profitable in each of the last three years. Results in each year benefited from stable loss severity.

Other personal coverages, which include insurance for personal valuable articles and excess liability, produced highly profitable results in each of the past three years, as favorable loss experience has continued.

Net premiums from commercial insurance, which represent 37% of our total writings, increased by 21% in 2003 compared with a 37% increase in 2002. The substantial premium growth in both years, which occurred in all segments of this business, was due in large part to significantly higher rates as well as an increase in our in-force policy count. Rates increased substantially in 2002 and 2003, although the level of rate increases in 2003 declined from 2002 levels as we experienced more competition in the U.S. marketplace across most lines of business. Despite this, retention levels have remained steady. New business accelerated toward the end of 2001. During 2002, we wrote more than two dollars of new business for every dollar of business we lost; during 2003, this ratio was about 1.7 to 1. The substantial growth in new business was produced with the same tightened underwriting discipline that existed over the past several years. We expect that rates will continue to rise but that the level of rate increases will continue to decline.

Our commercial insurance results were adversely affected by incurred losses of $250 million in 2003, $741 million in 2002 and $61 million in 2001 related to asbestos and toxic waste claims. Results in 2001 were also adversely affected by net costs of $103 million related to the September 11 attack. The combined loss and expense ratios for the classes of business within commercial insurance, as reported and as adjusted to exclude the effects of the asbestos and toxic waste losses and the September 11 attack, were as follows:

On an as adjusted basis, our commercial insurance business produced highly profitable results in 2003 and 2002 compared with unprofitable results in 2001. Results, as adjusted, have shown substantial improvement in each succeeding year. The improvement has been due in large part to the cumulative effect of price increases, better terms and conditions and more stringent risk selection in recent years.

Multiple peril results were highly profitable in 2003 compared with near breakeven results in 2002. The improved results were driven by the property component of this business where incurred losses were flat. Results in 2002 showed modest improvement over 2001 results, as adjusted, due to highly profitable overseas results. Losses from catastrophes other than the September 11 attack represented

Results for our casualty business, as adjusted, were highly profitable in 2003 and 2002 compared with unprofitable results in 2001. The improvement was due to higher rates and the culling of business where we could not attain price adequacy. In particular, the automobile component showed substantial improvement, producing highly profitable results in 2003 and 2002 compared with unprofitable results in 2001. Results for the primary liability component were profitable in all three years, improving in each succeeding year. The excess liability component produced near breakeven results in 2003 and 2002 compared with unprofitable results in 2001.

Workers’ compensation results were profitable in each of the past three years. The strong results were due to higher rates as well as our disciplined risk selection during the past several years.

Property and marine results were highly profitable in 2003 and 2002 compared with highly unprofitable results in 2001. Results in 2003 and 2002 benefited from improved pricing, higher deductibles, better terms and conditions and a low number of severe losses. The strong results in 2003 were achieved despite a $25 million loss that resulted from an adverse arbitration decision rendered against an insurance pool in which we were formerly a 5.5% participant. The decision related to a fire that occurred in 1995. Results in 2001 were adversely affected by a high frequency of large losses, both in the United States and overseas. Losses from catastrophes other than the September 11 attack represented 6.3 percentage points of the loss ratio for this class in 2003 compared with 6.6 percentage points in 2002 and 5.4 percentage points in 2001.

Net premiums from specialty insurance, which represent 40% of our total writings, increased by 31% in 2003 compared with a 34% increase in 2002. Premiums in 2001 included net reinsurance reinstatement premiums of $35 million related to the September 11 attack, primarily consisting of $80 million of premium revenue in our reinsurance business offset in part by costs of $40 million in our financial institutions business.

The growth in 2002 and 2003 in executive protection and the professional liability component of our financial institutions business was primarily attributable to higher rates. In response to claim severity trends, we initiated a program in the latter half of 2001 to increase pricing and improve policy terms and to not renew business that did not meet our underwriting criteria. We have implemented tighter terms and conditions, including lower policy limits and higher deductibles. We have continued to reprofile our book of business, generating most of our new business from small and middle market customers. Rate increases moderated during the latter half of 2003 due to increased competition in the marketplace. In the fidelity and standard commercial components of our financial institutions business, rate increases have begun to moderate as well.

Growth in our other specialty insurance business was primarily from Chubb Re, our reinsurance assumed business. We write only treaty reinsurance, primarily casualty reinsurance. Premiums produced by Chubb Re amounted to $984 million in 2003 compared with $488 million in 2002 and $199 million in 2001, excluding the net reinstatement premium revenue of $80 million.

Our specialty insurance results in 2001 were adversely affected by net costs of $512 million related to the September 11 attack and Enron-related surety losses of $220 million. Results in 2002 and 2003 benefited from reductions in surety losses related to Enron of $88 million and $17 million, respectively. The combined loss and expense ratios for the classes of business within specialty insurance, as reported and as adjusted to exclude the effects of the September 11 attack and the Enron surety losses and related benefits, were as follows:

Our specialty insurance underwriting results, as adjusted, were near breakeven in 2003 compared with unprofitable results in 2002 and profitable results in 2001.

Executive protection results were unprofitable in 2003 and 2002 compared with profitable results in 2001. Results in 2003 and 2002 were adversely affected by directors and officers liability and errors and omissions liability claim experience, particularly from claims that have arisen due to the corporate failures and allegations of management misconduct and accounting irregularities in recent years. The improvement in 2003 was in our European operations where results in 2002 were particularly unprofitable due to deteriorating loss trends caused by an increase in litigation, often involving European companies being sued in U.S. courts for securities fraud.

Our financial institutions business produced similarly unprofitable results in 2003 and 2002. Results in 2001, as adjusted, were profitable. The fidelity component of this business was highly profitable in each of the last three years due to favorable loss experience. Results for the professional liability component were highly unprofitable in 2003 and 2002 compared with modestly unprofitable results in 2001. The deterioration was due to the same adverse directors and officers liability and errors and omissions liability claim trends experienced in our executive protection business. Financial institutions continue to be the focus of scrutiny by regulators and the plaintiffs’ bar related to investment banking and mutual fund scandals. The standard commercial business written on financial institutions produced profitable results in all three years, reflecting the rate increases and more stringent risk selection in recent years.

Other specialty results, as adjusted, were highly profitable in 2003 and 2002 compared with near breakeven results in 2001. As adjusted, our surety results were highly profitable in each of the past three years. Our reinsurance assumed business generated by Chubb Re and our accident business were both profitable in 2003 and 2002 compared with modestly unprofitable results in 2001.

As a result of disarray in the surety reinsurance market caused by several years of declining prices and high losses, the availability of surety reinsurance in the near term has been significantly reduced. As a result, our future surety results could be more volatile.

Our surety business tends to be characterized by infrequent but potentially high severity losses. Since the end of 2001, we have been reducing our exposure on an absolute basis and by specific bond

Notwithstanding our efforts to manage and reduce our surety exposure, we continue to have substantial commercial surety exposure for outstanding bonds. In that regard, we have exposures related to commercial surety bonds issued on behalf of companies that have experienced deterioration in creditworthiness, including several gas forward purchase surety bonds. We therefore may experience an increase in filed claims and may incur high severity losses. Such losses would be recorded if and when claims are filed and determined to be valid, and could have a material adverse effect on the Corporation’s results of operations and liquidity.

In particular, we have in force $520 million of gas forward purchase surety bonds with one principal, Aquila, Inc. Our exposure under these bonds will decline over the terms of the bonds, which extend until 2012. These surety bonds, which are uncollateralized, secure Aquila’s obligation to supply gas under long-term forward purchase agreements. Under the terms of these bonds, our entire obligation to pay could be triggered if Aquila failed to provide gas under its forward purchase contracts or was the subject of a bankruptcy filing. There is currently no reinsurance in place covering our exposure under these bonds. Aquila continues to perform its obligations under the related gas forward purchase agreements.

A property and casualty subsidiary issued a reinsurance contract to an insurer who provides financial guarantees on debt obligations. At December 31, 2003, the amount of aggregate principal commitments related to this contract was approximately $350 million, net of reinsurance. These commitments expire by 2023.

Loss reserves, which are our property and casualty subsidiaries’ largest liability, include significant amounts related to asbestos and toxic waste claims, the September 11 attack and our Enron surety exposure. The components of our loss reserves were as follows:

The loss reserves related to asbestos and toxic waste claims, the September 11 attack and our Enron surety exposure are significant components of our total loss reserves, but they distort the growth trend in our loss reserves. Adjusted to exclude such loss reserves, our loss reserves, net of reinsurance recoverable, increased by $2,070 million or 19% in 2003 compared with $1,098 million or 11% in 2002.

Loss reserves for each of our business segments increased in 2002 and again in 2003. The increase was most significant in specialty insurance, due in large part to directors and officers and errors and omissions claim activity and the strong growth in our reinsurance assumed business. There was minimal loss reserve growth in commercial insurance in 2002, reflecting the exposure reductions over the several years prior to 2002.

Loss reserves include estimates for claims that have been reported and claims that have not been reported and include estimates of all expenses associated with settling those claims. Estimates are based upon past claim experience modified for current trends as well as prevailing economic, legal and social conditions.

We continually review and update our loss reserves. Based on all information currently available, we believe that the aggregate loss reserves of the property and casualty subsidiaries at December 31, 2003 were adequate to cover claims for losses that had occurred, including both those known to us and those yet to be reported. In establishing such reserves, we consider facts currently known and the present state of the law and coverage litigation. However, given the judicial decisions and legislative actions that have broadened the scope of coverage and expanded theories of liability in the past and the possibilities of similar interpretations in the future, particularly as they relate to asbestos claims and, to a lesser extent, toxic waste claims, additional liabilities may emerge in future periods for amounts in excess of carried reserves. Such increases in estimates could have a material adverse effect on the Corporation’s future operating results. However, management does not expect that any such increases would have a material effect on the Corporation’s consolidated financial condition or liquidity.

Because loss reserve estimates are subject to the outcome of future events, changes in estimates are unavoidable given that loss trends vary and time is required for changes in trends to be recognized and confirmed. As a result, the actual emergence of losses could vary, perhaps substantially, from the estimate of losses included in our financial statements, particularly when settlements may not occur until well into the future. Estimates are continually reviewed and updated as loss experience develops and new information becomes available. Any changes in estimates are reflected in operating results in the period in which the estimates are changed. Reserve changes that increase previous estimates of ultimate cost are referred to as unfavorable or adverse development or reserve strengthening. Reserve changes that decrease previous estimates of ultimate cost are referred to as favorable development or reserve releases.

A reconciliation of the beginning and ending loss reserves, net of reinsurance, for the three years ended December 31, 2003 is as follows:

During 2003, we experienced overall unfavorable development of $397 million on loss reserves established as of the previous year end. This compares with unfavorable one year development of $790 million in 2002 and favorable development of $196 million in 2001. Such development was reflected in operating results in these respective years.

The unfavorable development in 2003 was due primarily to two factors. First, we strengthened asbestos loss reserves by $250 million in the fourth quarter. Second, we experienced unfavorable development of about $140 million in our executive protection classes, principally directors and officers liability and errors and omissions liability, as adverse loss trends in recent accident years more than offset favorable loss experience in older accident years. The adverse development was due in large part to claims related to the corporate failures and allegations of management misconduct and accounting irregularities in recent years.

The unfavorable development in 2002 was due primarily to our strengthening asbestos and toxic waste loss reserves by $741 million during the year. In addition, we experienced unfavorable development of about $100 million in the homeowners class due to the increase in the severity of water damage and related mold claims. In the executive protection classes, the adverse loss trends in Europe and the United States in the more recent accident years more than offset favorable loss experience in the United States in older accident years, resulting in unfavorable development of about $50 million during 2002. Offsetting the unfavorable development somewhat was the $88 million reduction in surety loss reserves related to the Enron settlement.

The favorable development in 2001 was due primarily to favorable loss experience in our commercial excess liability and executive protection coverages, offset in part by losses incurred related to asbestos and toxic waste claims.

In Item 1 of this report, we present an analysis of our consolidated loss reserve development on a calendar year basis for each of the ten years prior to 2003.

Our U.S. property and casualty subsidiaries are required to file annual statements with insurance regulatory authorities prepared on an accounting basis prescribed or permitted by such authorities. These annual statements include an analysis of loss reserves, referred to as Schedule P, that presents accident year loss development information by line of business for the nine years prior to 2003. It is our intention to post the Schedule P for our combined U.S. property and casualty subsidiaries on our website as soon as it becomes available.

The process of establishing loss reserves is complex and imprecise as it must take into consideration many variables that are subject to the outcome of future events. As a result, subjective judgments as to our ultimate exposure to losses are an integral component of our loss reserving process.

We analyze loss reserves in two components: (1) reserves relating to all claims other than asbestos and toxic waste claims and (2) reserves relating to asbestos and toxic waste claims. Within the first component, we review each of the numerous classes of business as part of our overall analysis of loss reserves, taking into consideration the variety of trends that impact the ultimate settlement of claims in each particular class of business. Due to the multitude of such classes and the volume of detail for each, it would not be possible to provide complete quantitative actuarial claim data for all such classes, nor do we believe that such disclosure by class of business would be meaningful or useful to the reader.

Reserves Relating to Claims Other than Asbestos and Toxic Waste Claims. Our loss reserves include amounts related to short tail and long tail classes of business. Short tail classes consist principally of homeowners, commercial property and marine business. For these classes, the estimation of loss reserves is less complex because claims are generally reported and settled shortly after the loss occurs and the claims relate to tangible property.

Long-tail classes include directors and officers liability, errors and omissions liability and other executive protection coverages, commercial excess liability, and other liability classes. Most of our loss reserves relate to long tail liability classes of business. For many liability claims significant periods of time, ranging up to several years or more, may elapse between the occurrence of the loss, the reporting of the loss and the settlement of the claim. The longer the time span between the incidence of a loss and the settlement of the claim, the more the ultimate settlement amount can vary. For the long tail liability classes, a relatively small proportion of net losses in the more recent accident years are reported claims and an even smaller proportion are paid losses. Therefore, a relatively large proportion of our net losses for these classes are reserves for incurred but not reported (IBNR) losses — claims that had not yet been reported to us, some of which were not yet known to the insured, and future development on reported claims. In fact, approximately 60% of our aggregate net loss reserves at December 31, 2003 were for IBNR.

To estimate loss reserves, we use a variety of complex actuarial methods that analyze experience trends and other relevant factors. These methods generally utilize analyses of historical patterns of the development of paid and reported losses by accident year by class of business. This process relies on the basic assumption that past experience, adjusted for the effects of current developments and likely trends, is an appropriate basis for predicting future outcomes. For certain long tail classes of business where anticipated loss experience is less predictable because of the small number of claims and/or erratic claim severity patterns, estimates are based on both expected losses and actual reported losses. These classes include directors and officers liability, errors and omissions liability and commercial excess liability, among others. For these classes, we judgmentally set ultimate losses for each accident year based on our evaluation of loss trends and the current risk environment. The expected ultimate losses are adjusted as the accident years mature.

Our loss reserve review process does not calculate a range of loss reserve estimates. Using the various complex actuarial methods and different underlying assumptions, management selects the carried reserve for each class of business.

The inherent uncertainty in the process of establishing loss reserves arises from a number of factors. These factors include but are not limited to:


	•	Changes in the inflation rate for goods and services related to covered damages such as medical care and home repair costs,


	•	Changes in the judicial environment regarding the interpretation of policy provisions relating to the determination of coverage,

	•	Changes in the general attitude of juries in the determination of liability and damages,

	•	Changes in our estimates of the number and/or severity of claims that have been incurred but not reported as of the date of the financial statements,

	•	Changes in our underwriting standards and

	•	Any changes in our claim handling procedures.

In addition, we must consider the uncertain effects of emerging or potential claims and coverage issues. These issues can have a negative effect on our loss reserves by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims. Examples of emerging or potential claims and coverage issues include increases in the number and size of water damage claims related to remediation of mold conditions and increases in the number and size of directors and officers liability and errors and omissions liability claims arising out of investment banking practices and accounting and other corporate malfeasance. As a result of issues such as these, the uncertainties inherent in estimating ultimate claim costs on the basis of past experience have become increasingly unpredictable, further complicating the already complex loss reserving process. The future impact of these issues and other unforeseen emerging or potential claims and coverage issues is extremely hard to predict and could materially adversely affect the adequacy of our loss reserves.

Reserves Relating to Asbestos and Toxic Waste Claims. The uncertainties relating to asbestos and toxic waste claims on insurance policies written many years ago are exacerbated by inconsistent court decisions as well as judicial interpretations and legislative actions that in some cases have tended to broaden coverage beyond the original intent of such policies and in others have expanded theories of liability. The industry as a whole is engaged in extensive litigation over these coverage and liability issues and is thus confronted with a continuing uncertainty in its efforts to quantify these exposures.

Reserves for asbestos and toxic waste claims cannot be estimated with traditional actuarial techniques that rely on historical accident year loss development factors. Quantitative techniques have to be supplemented by subjective considerations including management judgment. It is therefore not possible to determine the future development of asbestos and toxic waste claims with the same degree of reliability as is the case for other types of claims. Such development will be affected by the extent to which courts and legislatures continue to expand the intent of the policies and the scope of the coverage. We establish case reserves and expense reserves for costs of related litigation where sufficient information has been developed to indicate the involvement of a specific insurance policy. In addition, IBNR reserves are established to cover additional exposures on both known and unasserted claims.

Asbestos Reserves. Asbestos remains the most significant and difficult mass tort for the insurance industry in terms of claims volume and dollar exposure. Asbestos claims relate primarily to bodily injuries asserted by those who came in contact with asbestos or products containing asbestos. Early court cases established the “continuous trigger” theory with respect to insurance coverage. Under this theory, insurance coverage is deemed to be triggered from the time a claimant is first exposed to asbestos until the manifestation of any disease. This interpretation of a policy trigger can involve insurance companies over many years and increases their exposure to liability.

The plaintiffs’ bar continues to solicit new claimants through extensive advertising and through asbestos medical screenings. Litigation is then initiated even though many of the claimants do not show any signs of asbestos-related disease. Thus, new asbestos claims and new exposures on existing claims have continued unabated despite the fact that usage of asbestos has declined since the mid-1970’s. Based on published projections, we expect that we will continue receiving asbestos claims at the current rate for at least the next several years.

To date, approximately 70 manufacturers and distributors of asbestos products have filed for bankruptcy protection as a result of asbestos liabilities. The rapid increase in both the frequency and severity of claims in recent years accelerated the pace at which these bankruptcies were filed.

Our most significant individual asbestos exposures involve product liability on the part of “traditional” defendants who manufactured, distributed or installed asbestos products. We wrote excess liability and/or general liability coverages for these insureds. While these insureds are relatively few in number, such exposure has increased in recent years due to the increased volume of claims, the erosion of much of the underlying limits and the bankruptcies of target defendants.

Our other asbestos exposures involve product and non-product liability on the part of “peripheral” defendants, including a mix of manufacturers, distributors and installers of certain products that contain asbestos in small quantities and owners of properties on which asbestos exists. Generally, these insureds are named defendants on a regional rather than a nationwide basis. As the financial resources of traditional asbestos defendants have been depleted, plaintiffs are targeting these viable peripheral parties with greater frequency and, in many cases, for larger awards.

Asbestos claims against the major manufacturers, distributors or installers of asbestos products were presented under the products liability section of primary general liability policies as well as under excess liability policies, both of which typically had aggregate limits that capped an insurer’s liability. In recent years, a number of asbestos claims by insureds are being presented as “non-products” claims, such as those by installers of asbestos products and by property owners who allegedly had asbestos on their property, under the premises or operations section of primary general liability policies. Unlike products exposures, these non-products exposures typically had no aggregate limits, creating potentially greater exposure. Further, in an effort to seek additional insurance coverage, some insureds with installation activities who have substantially eroded their products coverage are presenting new asbestos claims as non-products operations claims or attempting to reclassify previously settled products claims as non-products claims to restore a portion of previously exhausted products aggregate limits. It is difficult to predict whether insureds will be successful in asserting claims under non-products coverage or whether insurers will be successful in asserting additional defenses. Therefore, the impact of such efforts on insurers is uncertain.

The expanded focus of asbestos litigation beyond asbestos manufacturers and distributors to installers and premises owners has created, in some instances, conflicts among insureds, primary insurers and excess insurers, mainly involving questions regarding allocation of indemnity and expense costs and exhaustion of policy limits. These issues are generating costly coverage litigation with the potential for inconsistent results.

In establishing our asbestos reserves, we evaluate the exposure presented by each insured. As part of this evaluation, we consider the available insurance coverage; limits and deductibles; the jurisdictions involved; past settlement values of similar claims; the potential role of other insurance, particularly underlying coverage below our excess liability policies; and applicable coverage defenses, including asbestos exclusions.

We have assumed a continuing unfavorable legal environment with no benefit from any federal asbestos reform legislation. A recent proposal, which envisioned a sizable trust funded primarily by defendants and insurers, appears highly unlikely to pass.

In the third quarter of 2002, our actuaries and claim personnel together with our outside actuarial consultants commenced their periodic ground-up exposure-based analysis of our asbestos related liabilities. As part of this analysis, they considered the following adverse trends:


	•	Estimates of the ultimate liabilities for traditional asbestos defendants have increased as the number of plaintiff claims has surged over the past few years. The notable increase in claimants as well as potential future claimants has resulted in large settlements of asbestos related litigation. As a result, it now appears more likely that many of these traditional defendants will


		access higher excess layers of insurance coverage as well as more years of coverage than previously anticipated.

	•	Claims have been more aggressively pursued against peripheral asbestos defendants in recent years, partly in response to the bankruptcy or exhaustion of insurance coverage for many of the major traditional defendants.

	•	The number of claims filed under the non-aggregate premises or operations section of general liability policies has increased, creating potentially greater exposure.

	•	The litigation environment has become increasingly adverse. More than half of lawsuits filed in recent years have been filed in five plaintiff oriented states, where significant verdicts historically have been rendered against commercial defendants.

	•	The number of asbestos defendants in bankruptcy has increased, resulting in an increase in the number and cost of declaratory judgment lawsuits to resolve coverage disputes and to effect settlements in the bankruptcy courts.

Upon completion of the analysis and assessment of the results, we increased our net asbestos loss reserves by $545 million in the third quarter of 2002. Following a thorough review in the fourth quarter by our internal actuarial, claim and reinsurance personnel, we reduced our estimate of reinsurance recoverable on potential asbestos claims. As a result, our net asbestos loss reserves increased by an additional $75 million.

In the fourth quarter of 2003, our actuaries and claim personnel together with our outside actuarial consultants performed a rigorous update of their 2002 ground-up exposure-based analysis of our asbestos related liabilities. The review noted the same adverse trends observed during the 2002 analysis, particularly a further increase in estimates of the ultimate liabilities for several of our traditional asbestos defendants. In addition, the number of insureds for whom we established reserves and the average severity of claims were both higher than anticipated. Upon completion of the update, we increased our net asbestos loss reserves by $250 million.

The following table presents a reconciliation of the beginning and ending loss reserves related to asbestos claims.

Significant uncertainty remains as to our ultimate liability relating to asbestos related claims. This uncertainty is due to such factors as the long latency period between asbestos exposure and disease manifestation and the resulting potential for involvement of multiple policy periods for individual claims as well as the increase in the volume of claims by unimpaired plaintiffs and the increase in claims filed under the non-aggregate premises or operations section of general liability policies. There is also the possibility, however remote, of federal legislation that would address the asbestos problem.

Toxic Waste Reserves. Toxic waste claims relate primarily to pollution and related cleanup costs. Our insureds have two potential areas of exposure — hazardous waste dump sites and pollution at the insured site primarily from underground storage tanks and manufacturing processes.

Most PRPs named to date are parties who have been generators, transporters, past or present landowners or past or present site operators. The PRPs disposed of toxic materials at a waste dump site or transported the materials to the site. These PRPs had proper government authorization in many instances. Insurance policies issued to PRPs were not intended to cover the clean-up costs of pollution and, in many cases, did not intend to cover the pollution itself. Pollution was not a recognized hazard at the time many of these policies were written. In more recent years, however, policies specifically exclude such exposures.

As the costs of environmental clean-up became substantial, PRPs and others increasingly filed claims with their insurance carriers. Litigation against insurers extends to issues of liability, coverage and other policy provisions.

There is substantial uncertainty involved in estimating our liabilities related to these claims. First, the liabilities of the claimants are extremely difficult to estimate. At any given site, the allocation of remediation costs among governmental authorities and the PRPs varies greatly depending on a variety of factors. Second, different courts have addressed liability and coverage issues regarding pollution claims and have reached inconsistent conclusions in their interpretation of several issues. These significant uncertainties are not likely to be resolved definitively in the near future.

Uncertainties also remain as to the Superfund law itself. Superfund’s taxing authority expired on December 31, 1995 and has not been re-enacted. Federal legislation appears to be at a standstill. At this time, it is not possible to predict the direction that any reforms may take, when they may occur or the effect that any changes may have on the insurance industry.

Without federal movement on Superfund reform, the enforcement of Superfund liability is shifting to the states. States are being forced to reconsider state-level cleanup statutes and regulations. As individual states move forward, the potential for conflicting state regulation becomes greater. Significant uncertainty remains as to the cost of remediating the state sites. Because of the large number of state sites, such sites could prove even more costly in the aggregate than Superfund sites.

In establishing our toxic waste reserves, we evaluate the exposure presented by each insured. As part of this evaluation, we consider the probable liability, available insurance coverage, past settlement values of similar exposures as well as facts that are unique to each insured.

Uncertainty remains as to our ultimate liability relating to toxic waste claims. However, toxic waste losses appear to be developing as expected due to relatively stable claim trends. In many cases, claims are being settled for less than initially anticipated due to more efficient site remediation efforts. In other cases, we have been successful at buying back our policies.

Despite the stable claim trends, we increased our toxic waste loss reserves by $80 million in the third quarter of 2002 based on the estimate of our actuaries and actuarial consultants as to our ultimate exposure.

The following table presents a reconciliation of the beginning and ending loss reserves, net of reinsurance recoverable, related to toxic waste claims. There are virtually no reinsurance recoveries related to these claims.

Our property and casualty subsidiaries have exposure to losses caused by hurricanes, earthquakes, winter storms, windstorms and other natural catastrophic events. The frequency and severity of natural catastrophes are unpredictable.

The extent of losses from a catastrophe is a function of both the total amount of insured exposure in an area affected by the event and the severity of the event. We continually assess our concentration of underwriting exposures in catastrophe prone areas globally and develop strategies to manage this exposure through individual risk selection, subject to regulatory constraints, and through the purchase of catastrophe reinsurance. In recent years, we have invested in modeling technologies and concentration management tools that allow us to better monitor and control our accumulations of potential losses from catastrophe exposures. We maintain records showing concentrations of risk in catastrophe exposed areas such as California (earthquake and brush fires) and the gulf and east coasts of the United States (hurricanes). We also continue to explore and analyze credible scientific evidence, including the impact of global climate change, that may affect our potential exposure under insurance policies.

Despite these efforts, the occurrence of one or more severe catastrophic events in heavily populated areas could have a material adverse effect on the Corporation’s results of operations, financial condition or liquidity.

The tragic event of September 11 changed the way the property and casualty insurance industry views catastrophic risk. Numerous classes of business have become exposed to terrorism related catastrophic risks in addition to the catastrophic risks related to natural occurrences. This has required us to change how we identify and evaluate risk accumulations. We have changed our underwriting protocols to address terrorism and the limited availability of terrorism reinsurance. However, given the uncertainty of the potential threats, we cannot be sure that we have addressed all the possibilities.

The Terrorism Risk Insurance Act of 2002 (the Terrorism Act) was signed into law on November 26, 2002. The Terrorism Act established a temporary program under which the federal government will share the risk of loss from certain acts of international terrorism with the insurance industry. The program terminates on December 31, 2005. The Terrorism Act is applicable to almost all commercial lines of insurance. Insurance companies with direct commercial insurance exposure in the United States are required to participate in the program. Each insurer has a separate deductible in the event of an act of terrorism before federal assistance becomes available. The deductible is based on a percentage of direct commercial earned premiums from the previous calendar year. For 2004, that deductible is 10% of direct commercial premiums earned in 2003. For losses above the deductible, the federal government will pay for 90% of covered losses, while the insurer contributes 10%. There is a combined annual aggregate limit for the federal government and all insurers of $100 billion; above this amount, insurers are not liable for covered losses. For certain classes of business, such as workers’

compensation, terrorism coverage is mandatory. For those classes of business where it is not mandatory, insureds may choose not to accept the terrorism coverage, which would reduce our exposure. While the provisions of the Terrorism Act will serve to mitigate our exposure in the event of a large-scale terrorist attack, our deductible is substantial, approximating $600 million in 2004. Therefore, we are making a concerted effort to monitor and control terrorism risk aggregations. However, our future operating results could be more volatile due to the limited terrorism coverage in our reinsurance program.

We also have exposure outside the United States to risk of loss from acts of terrorism. In some jurisdictions, we have access to government mechanisms that would mitigate our exposure.

Property and casualty investment income before taxes increased by 14% in 2003 compared with 2002 and by 3% in 2002 compared with 2001. Growth in both years was due to an increase in invested assets, which reflected substantial cash flow from operations over the period. Growth in 2003 also benefited from capital contributions to the property and casualty subsidiaries by the Corporation of $1 billion in the fourth quarter of 2002 and $800 million in the second quarter of 2003. Growth in 2002 benefited from a capital contribution in the fourth quarter of 2001 that added $500 million to the invested assets of the property and casualty subsidiaries. Lower available reinvestment rates on fixed maturities that matured in each year dampened growth in investment income.

The effective tax rate on our investment income was 20.3% in 2003 compared with 18.2% in 2002 and 17.0% in 2001. The effective tax rate increased each year as a result of our holding a smaller proportion of our investment portfolio in tax-exempt securities.

On an after-tax basis, property and casualty investment income increased by 11% in 2003 and 2% in 2002. Management uses property and casualty investment income after-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.

Other charges include miscellaneous income and expenses of the property and casualty subsidiaries.

Other charges in 2003 included expenses of $18 million related to the restructuring of our operations in Continental Europe. The restructuring costs consist primarily of severance costs related to branch closings and work force reductions.

Other charges in 2001 included goodwill amortization of approximately $20 million. The accounting for goodwill was changed in 2002 as discussed further under “Changes in Accounting Principles”. As a result, there was no goodwill amortization in 2003 and 2002.

Other charges in 2001 also included the $10 million charge for our share of the losses of Hiscox plc from the September 11 attack.

Chubb Financial Solutions (CFS) was organized in 2000 to develop and provide customized products to address specific financial needs of corporate clients. CFS operated through both the capital and insurance markets. The insurance and reinsurance solutions were written by our property and casualty subsidiaries, and the results of such business are included within our underwriting results.

In April 2003, the Corporation announced its intention to exit CFS’s non-insurance business and to run-off the existing financial products portfolio. Our objective is to exit this business as quickly as

CFS’s non-insurance business was primarily structured credit derivatives, principally as a counterparty in portfolio credit default swap contracts. The Corporation guaranteed all of these obligations.

In a typical portfolio credit default swap, CFS participated in the senior layer of a structure designed to replicate the performance of a portfolio of corporate securities, a portfolio of asset-backed securities or a specified pool of loans. The structure of these portfolio credit default swaps generally requires CFS to make payment to counterparties to the extent cumulative losses, related to numerous credit events, exceed a specified threshold. The risk below that threshold, referred to as subordination, is assumed by other parties with the primary risk layer sometimes retained by the buyer. The amount of subordination for each contract varies based on the credit quality of the underlying portfolio and the term to maturity of the contract. Credit events generally arise when one of the referenced entities within a portfolio becomes bankrupt, undergoes a debt restructuring or fails to make timely interest or principal payments.

Portfolio credit default swaps are derivatives and are carried in the financial statements at estimated fair value, which represents management’s best estimate of the cost to exit our positions. Most of these credit default swaps tend to be unique transactions and there is no traded market for such exposures. To estimate the fair value of the obligation in each credit default swap, we use internal valuation models that are similar to external valuation models.

The fair value of our credit default swaps is subject to fluctuations arising from, among other factors, changes in credit spreads, the financial ratings of referenced asset-backed securities, actual credit events reducing subordination, credit correlation within a portfolio, anticipated recovery rates related to potential defaults and changes in interest rates. Changes in fair value are included in income in the period of the change. Thus, CFS’s results are subject to volatility, which has had a significant effect on the Corporation’s results of operations from period to period. The market risks associated with our obligations under portfolio credit default swaps are discussed under the Financial Products section of Quantitative and Qualitative Disclosures About Market Risk.

The non-insurance business of CFS produced a loss before taxes of $127 million in 2003 compared with a loss of $70 million in 2002 and income of $9 million in 2001.

The loss in 2002 was due to adverse movement in the mark-to-market adjustment, which resulted in an increase in the fair value of our future obligations related to the portfolio credit default swaps. Of the increase in the fair value of our obligations, $53 million was due to downgrades in the financial ratings of certain referenced securities underlying two of our asset backed portfolio credit default swaps. Other factors contributing to the increase were a widening of market credit spreads and, for one credit default swap, erosion in the risk layers that are subordinate to the CFS risk layer due to actual losses in those subordinate layers.

The substantial loss in 2003 was due to further deterioration in the credit quality of certain referenced securities underlying the two asset-backed credit default swaps. In the first nine months of the year, the fair value of our future obligations related to these two swaps increased by $70 million. Then, in the fourth quarter, as described below, we terminated the two swaps and replaced them with a principal and interest guarantee agreement, which resulted in an additional loss of $96 million. The losses related to these two asset-backed swaps were partially offset by mark-to-market gains during the year on our corporate credit default swaps.

Revenues from the non-insurance business of CFS, primarily consisting of the change in fair value of derivatives contracts, were negative $62 million in 2003, negative $51 million in 2002 and positive $29 million in 2001. Revenues were negative in 2003 and 2002 due to the adverse impact of changes in fair value in both years and the impact in 2003 of the agreement to terminate the two asset-backed portfolio credit default swaps and replace them with a principal and interest guarantee.

CFS’s aggregate exposure, or retained risk, from its in-force portfolio credit default swaps is referred to as notional amount. Notional amounts are used to express the extent of involvement in swap transactions. These amounts are used to calculate the exchange of contractual cash flows and are not necessarily representative of the potential for gain or loss. The notional amounts are not recorded on the balance sheet.

At December 31, 2002, the notional amount of CFS’s credit default swaps was approximately $38.7 billion, of which $3.9 billion related to the two asset-backed swaps that had experienced deterioration in credit quality. In connection with our plan to exit the credit derivatives business, we have accelerated the reduction of our notional exposure.

In the fourth quarter of 2003, CFS paid $50 million to terminate the two asset-backed portfolio credit default swaps that had experienced deterioration in credit quality and simultaneously entered into a new contract that guarantees principal and interest obligations on only $2.3 billion of the original $3.9 billion notional amount. The Corporation has guaranteed CFS’s obligations under the new contract. CFS’s potential payment obligations have been extended from the original termination dates of 2007 and 2008 to the date when the last of the underlying obligations expire. Under the new agreement, CFS’s maximum payment obligation is limited to $500 million regardless of the amount of losses that might be incurred on the $2.3 billion of referenced securities. Moreover, if losses are incurred, CFS’s payment obligations are limited to an extended payment schedule under which no payment would be due until 2010 at the earliest.

CFS established a liability of $186 million related to the new principal and interest contract, which represented the estimated fair value of the guarantee at its inception. At the same time, CFS eliminated the carried liability of $140 million on the two swaps that were terminated.

The principal and interest guarantee is not a derivative contract. Therefore, the liability related to this contract will not be marked-to-market each period. Due to the nature of the guarantee, we will reduce this liability only upon either the expiration or settlement of the guarantee. If actual losses are incurred, a liability for the losses will be established, and a portion of the guarantee liability will be released. The amount released will depend on our evaluation of expected ultimate loss experience.

During 2003, CFS terminated its obligations under certain other portfolio credit default swaps. In addition, CFS entered into a portfolio credit default swap that exactly offsets the provisions of an in force credit default swap with a notional exposure of $500 million. These transactions had almost no impact on CFS’s results of operations.

As a result of these transactions, the notional amount of CFS’s credit default swaps was reduced to $24.7 billion at December 31, 2003. Our realistic loss exposure is a very small portion of the $24.7 billion notional amount due to several factors. Our position is senior to subordinated interests of $5.9 billion in the aggregate. Of the $5.9 billion of subordination, there were only $37 million of defaults through December 31, 2003, none of which has pierced the subordination limits of any of our contracts. In addition, using our internal ratings models, we estimate that the credit ratings of the individual portfolio credit default swaps at December 31, 2003 were either AAA or AA.

In addition to portfolio credit default swaps, CFS entered into a derivative contract linked to an equity market index and a few other insignificant non-insurance transactions.

The notional amount and fair value of our future obligations under derivative contracts by type of risk were as follows:

Corporate and other includes investment income earned on corporate invested assets, interest expense and other expenses not allocated to the operating subsidiaries, and the results of our real estate and other non-insurance subsidiaries. Corporate and other produced a loss before taxes of $157 million in 2003 compared with losses of $74 million and $23 million in 2002 and 2001, respectively. The increasingly higher loss in 2002 and 2003 was due to an increase in interest expense and a decrease in investment income in each of the years compared with the prior year. Interest expense increased in 2003 due to the issuance of $600 million of debt in the fourth quarter of 2002, $500 million of debt in the first quarter of 2003 and $460 million of debt in the second quarter of 2003. The higher interest expense in 2002 was due to the issuance of $600 million of debt in the fourth quarter of 2001. The decrease in investment income in 2002 and again in 2003 was due to lower average corporate invested assets resulting from the capital contributions to the property and casualty subsidiaries.

Results in 2003 included a loss at The Chubb Institute, Inc., our post secondary educational subsidiary, which provides programs primarily relating to information technology. As part of our focus on our core insurance business, we are analyzing our alternatives with respect to Chubb Institute. The effect of this loss on 2003 results was substantially offset by income from our investment in Allied World Assurance Company, Ltd.

Real estate operations resulted in a loss before taxes of $14 million in 2003 compared with losses of $6 million in 2002 and $4 million in 2001. These amounts are included in the corporate and other results. In each year, we sold selected commercial properties as well as residential properties. Real estate revenues were $72 million in 2003, $76 million in 2002 and $87 million in 2001.

We own approximately $285 million of land which we expect will be developed in the future. In addition, our real estate assets include approximately $180 million of commercial properties and land parcels under lease, of which $23 million related to a variable interest entity in which we are the primary beneficiary. We are continuing to explore the sale of certain of our remaining properties.

The recoverability of the carrying value of our real estate assets is assessed based on our ability to fully recover costs through a future revenue stream. The assumptions used reflect future improvement in demand for office space, an increase in rental rates and the ability and intent to obtain financing in order to hold and develop such remaining properties and protect our interests over the long term. Management believes that it has made adequate provisions for impairment of real estate assets. However, if the assets are not sold or developed or if leased properties do not perform as presently

A primary reason for the sale of fixed maturities in each of the last three years has been to improve our after-tax portfolio return without sacrificing quality where market opportunities have existed to do so.

We regularly review our invested assets with a fair value below cost to determine if an other than temporary decline in value has occurred. In evaluating whether a decline in value of any investment is other than temporary, we consider various quantitative and qualitative factors including the length of time and the extent to which the fair value has been less than the cost, the financial condition and near term prospects of the issuer, whether the debtor is current on contractually obligated interest and principal payments, and our intent and ability to hold the investment for a period of time sufficient to allow us to recover our cost. If a decline in the fair value of an individual security is deemed to be other than temporary, the difference between cost and estimated fair value is charged to income as a realized investment loss. The fair value of the investment becomes its new cost basis.

The writedowns of fixed maturities in 2003 were primarily due to collateral deterioration of several asset-backed securities and price declines of a few corporate credits in the airline and energy sectors.

The writedowns in 2002 and 2001 were primarily due to credit deterioration and corporate failures of several issuers, particularly in the telecommunications and, to a lesser extent, energy-related industries.

We establish deferred income taxes on the undistributed earnings of foreign subsidiaries. Similarly, we establish deferred tax assets related to the expected future U.S. tax benefit of losses and foreign taxes incurred by our foreign subsidiaries. To evaluate the realization of the future tax benefit of these deferred tax assets, management must consider whether it is more likely than not that sufficient taxable income will be generated. Management’s judgment is based on its assessment of business plans and related projections of future taxable income that reflect assumptions about increased premium volume, higher rates and improved policy terms as well as available tax planning strategies. The tax loss carryforwards and foreign tax credits have no expiration. However, we are

During the years 2000 through 2002, Chubb Insurance Company of Europe (Chubb Europe) incurred substantial losses. These losses were the result of underwriting losses during the period due to inadequate prices and adverse claims trends, particularly for directors and officers liability and errors and omissions liability coverages. At December 31, 2002, the deferred income tax asset related to the expected future U.S. tax benefit of the losses and foreign taxes incurred by Chubb Europe was $140 million. During the fourth quarter of 2002, we established a valuation allowance of $40 million for the portion of these tax assets that we could not recognize for accounting purposes due to the requirement to evaluate realization over a near term horizon.

Due to profitable results in Chubb Europe during 2003, as of December 31, 2003, the deferred income tax asset related to the expected future U.S. tax benefit of the losses and foreign taxes incurred by Chubb Europe had been reduced to $100 million. As a result, in the fourth quarter of 2003, we concluded that it is more likely than not that the deferred tax assets will be realized over a near term horizon and we eliminated the valuation allowance.

Capital resources and liquidity represent the overall financial strength of the Corporation and its ability to generate cash flows from its operating subsidiaries, borrow funds at competitive rates and raise new capital to meet operating and growth needs.

Capital resources provide protection for policyholders, furnish the financial strength to support the business of underwriting insurance risks and facilitate continued business growth. At December 31, 2003, the Corporation had shareholders’ equity of $8.5 billion and total debt of $2.8 billion.

In March 2003, the Corporation issued $225 million of unsecured 3.95% notes due in 2008 and $275 million of unsecured 5.2% notes due in 2013. Net proceeds from the issuance of the notes were $495 million.

In June 2003, a shelf registration statement that the Corporation filed in March 2003 was declared effective by the Securities and Exchange Commission. Under the registration statement, up to $2.5 billion of various types of securities may be issued. At December 31, 2003, the Corporation had approximately $650 million remaining under the shelf registration statement.

In June 2003, the Corporation sold 15,525,000 shares of common stock. Net proceeds from the sale of the shares were $887 million. Concurrently, the Corporation issued $460 million of unsecured 2.25% senior notes due in 2008 and 18.4 million purchase contracts. The senior notes and purchase contracts were issued together in the form of 7% equity units, each of which initially represents $25 principal amount of senior notes and one purchase contract. The net proceeds from this offering were $446 million. Each purchase contract obligates the investor to purchase for $25 a variable number of shares of the Corporation’s common stock on August 16, 2006. The number of shares to be purchased will be determined based on a formula that considers the market price of our common stock immediately prior to the time of settlement in relation to the $59.50 per share sale price of our common stock at the time the equity units were offered. Upon settlement of the purchase contracts, the Corporation will receive proceeds of approximately $460 million and will issue between approximately 6,500,000 and 7,700,000 shares of common stock.

In 2002, the Corporation issued $600 million of unsecured 4% senior notes due in 2007 and 24 million mandatorily exercisable warrants to purchase the Corporation’s common stock. The senior notes and warrants were issued together in the form of 7% equity units, each of which initially

represents $25 principal amount of senior notes and one warrant. The net proceeds were $582 million. Each warrant obligates the investor to purchase for $25 a variable number of shares of the Corporation’s common stock on or before November 16, 2005. The number of shares to be purchased will be determined based on a formula that considers the market price of our common stock immediately prior to the time of settlement in relation to the $56.64 per share sale price of our common stock at the time the equity units were offered. Upon settlement of the warrants, the Corporation will receive proceeds of approximately $600 million and will issue between approximately 8,700,000 and 10,600,000 shares of common stock.

The equity units are further described in Notes (10)(a) and (20)(c) of the Notes to Consolidated Financial Statements.

The proceeds from the issuance of the notes, the common stock and the equity units are being used for general corporate purposes, including capital contributions to our property and casualty subsidiaries to support growth.

The Corporation also has outstanding $300 million of unsecured 6.15% notes due in 2005, $400 million of unsecured 6% notes due in 2011, $100 million of unsecured 6.6% debentures due in 2018 and $200 million of unsecured 6.8% debentures due in 2031.

Chubb Executive Risk Inc., a wholly owned subsidiary of the Corporation, has outstanding $75 million of unsecured 7 1/8% notes due in 2007. Executive Risk Capital Trust, wholly owned by Chubb Executive Risk, has outstanding $125 million of 8.675% capital securities. The sole assets of the Trust are debentures issued by Chubb Executive Risk. The capital securities are subject to mandatory redemption in 2027 upon repayment of the debentures. The capital securities are also subject to mandatory redemption under certain circumstances beginning in 2007. The Corporation has guaranteed the unsecured notes and the capital securities.

Management continuously monitors the amount of capital resources that the Corporation maintains both for itself and its operating subsidiaries. In connection with our long-term capital strategy, the Corporation from time to time contributes capital to its property and casualty subsidiaries. In addition, in order to satisfy its capital needs as a result of any rating agency capital adequacy or other future rating issues, or in the event the Corporation were to need additional capital to make strategic investments in light of market opportunities, the Corporation may take a variety of actions, which could include the issuance of additional debt and/or equity securities.

In July 1998, the Board of Directors authorized the repurchase of up to 12,500,000 shares of the Corporation’s common stock. In June 2001, the Board of Directors authorized the repurchase of up to an additional 16,000,000 shares. The 1998 authorization has no expiration; the 2001 authorization expired on June 30, 2003. As of December 31, 2003, 3,287,100 shares remained under the 1998 share repurchase authorization. The Corporation made no share repurchases during 2003. The Corporation repurchased 1,500,000 shares in open-market transactions in 2002 at a cost of $99 million and 7,971,600 shares in 2001 at a cost of $556 million. We do not anticipate that we will repurchase any shares of our common stock in 2004.

The Corporation and its insurance subsidiaries are rated by major rating agencies. These ratings reflect the rating agency’s opinion of our financial strength, operating performance, strategic position and ability to meet our obligations to policyholders. Standard & Poor’s Ratings Services lowered certain of our ratings in the first quarter of 2003. Following the announcement of our fourth quarter 2003 earnings, which included charges taken to strengthen our asbestos loss reserves and to limit our exposure on the two credit default swaps written by CFS that had experienced deterioration in credit quality, Moody’s Investors Service lowered our debt ratings and changed to negative the outlook for our ratings.

The following table summarizes the Corporation’s credit ratings from the major independent rating organizations as of March 9, 2004.

The following table summarizes our property and casualty subsidiaries’ financial strength ratings from the major independent rating organizations as of March 9, 2004.

Ratings are an important factor in establishing our competitive position in our operating businesses. There can be no assurance that our ratings will continue for any given period of time or that they will not be changed. Further reductions in our ratings could adversely affect the competitive position of our operating businesses.

It is possible that positive or negative ratings actions may occur in the future. If our ratings were downgraded, the Corporation may incur higher borrowing costs and may have more limited means to access capital.

The following table provides our future payments due by period under contractual obligations as of December 31, 2003, aggregated by type of obligation.

The Corporation had certain commitments totaling $394 million at December 31, 2003 to fund limited partnership investments. These capital commitments can be called by the partnerships during the commitment period (on average, 1-4 years) to fund working capital needs or the purchase of new investments.

The Corporation does not have any material off-balance sheet arrangements, except as discussed in Note (16) of the Notes to Consolidated Financial Statements.

Liquidity is a measure of our ability to generate sufficient cash flows to meet the short and long term cash requirements of our business operations.

Our property and casualty operations provide liquidity in that premiums are generally received months or even years before losses are paid under the policies purchased by such premiums. Historically, cash receipts from operations, consisting of insurance premiums and investment income, have provided more than sufficient funds to pay losses, operating expenses and dividends to the Corporation. After satisfying our cash requirements, excess cash flows are used to build the investment portfolio and thereby increase future investment income.

New cash from operations available for investment by the property and casualty subsidiaries was approximately $3.1 billion in 2003 compared with $1.9 billion in 2002 and $570 million in 2001. New cash available in 2003 was higher than in 2002 due to the substantial growth in premium receipts in 2003 without a commensurate increase in paid losses or operating expenses. The increase in new cash in 2002 was due to the significant growth in premium receipts while paid losses were similar in 2002 and 2001.

In addition to the cash from operations, the property and casualty subsidiaries received capital contributions from the Corporation of $800 million in the second quarter of 2003, $1 billion in the fourth quarter of 2002 and $750 million in the fourth quarter of 2001. In 2001, $250 million was used by a property and casualty subsidiary to fund the purchase of a 19% interest in Allied World Assurance Holdings, Ltd, a newly formed Bermuda-based insurer. In 2002, the interest in Allied World Assurance Holdings was transferred as a dividend from the property and casualty subsidiary to the Corporation.

Our property and casualty subsidiaries maintain investments in highly liquid, short-term and other marketable securities to provide for immediate cash needs.

The Corporation’s liquidity requirements in the past have been met by dividends from its property and casualty subsidiaries and the issuance of commercial paper and debt and equity securities. Liquidity requirements in the future will be met by these sources of funds as well as borrowings from its credit facilities.

The declaration and payment of future dividends to the Corporation’s shareholders will be at the discretion of the Corporation’s Board of Directors and will depend upon many factors, including our operating results, financial condition, capital requirements and any regulatory constraints.

As a holding company, the Corporation’s ability to continue to pay dividends to shareholders and to satisfy its obligations, including the payment of interest and principal on debt obligations, relies on the availability of liquid assets in the Corporation, which is dependent in large part on the dividend paying ability of its property and casualty subsidiaries. Various state insurance laws restrict the Corporation’s property and casualty subsidiaries as to the amount of dividends they may pay without the prior approval of regulatory authorities. The restrictions are generally based on net income and on certain levels of policyholders’ surplus as determined in accordance with statutory accounting practices. Dividends in excess of such thresholds are considered “extraordinary” and require prior regulatory approval. During 2003, these subsidiaries paid cash dividends to the Corporation totaling $270 million. The maximum dividend distribution that may be made by the property and casualty subsidiaries to the Corporation during 2004 without prior approval is approximately $630 million.

We believe that our strong financial position and conservative debt level provide us with the flexibility and capacity to obtain funds externally through debt or equity financings on both a short term and long term basis. However, should our ratings be downgraded, our ability to access the markets to satisfy our liquidity requirements could be adversely affected.

The Corporation has two credit agreements with a group of banks that provide for unsecured borrowings of up to $500 million in the aggregate. The $250 million short term revolving credit facility, which was to have terminated on June 27, 2003, was extended to June 24, 2004 and may be renewed or replaced. The $250 million medium term revolving credit facility terminates on June 28, 2007. On the respective termination dates for these agreements, any loans then outstanding become payable. There have been no borrowings under these agreements. Various interest rate options are available to the Corporation, all of which are based on market interest rates. The facilities are available for general corporate purposes and to support the Corporation’s commercial paper borrowing arrangement.

The main objectives in managing our investment portfolios are to maximize after-tax investment income and total investment returns while minimizing credit risks in order to provide maximum support to the insurance underwriting operations. Investment strategies are developed based on many

factors including underwriting results and our resulting tax position, regulatory requirements, fluctuations in interest rates and consideration of other market risks. Investment decisions are centrally managed by investment professionals based on guidelines established by management and approved by the boards of directors.

Our investment portfolio is primarily comprised of high quality bonds, principally tax-exempt, U.S. Treasury and government agency, mortgage-backed securities and corporate issues as well as foreign bonds that support our international operations. In addition, the portfolio includes equity securities held primarily with the objective of capital appreciation.

In 2003, we invested new cash in tax-exempt bonds and taxable bonds and, to a lesser extent, equity securities. The taxable bonds were primarily mortgage-backed securities, foreign government bonds and U.S. Treasury securities. In 2002, we invested new cash in mortgage-backed securities and, to a lesser extent, U.S. Treasury securities. In 2001, we invested new cash primarily in corporate bonds. Our objective is to achieve the appropriate mix of taxable and tax-exempt securities in our portfolio to balance both investment and tax strategies. At December 31, 2003, 51% of our fixed maturity portfolio was invested in tax-exempt bonds compared with 53% at December 31, 2002 and 59% at December 31, 2001.

Fixed maturity securities that we have the ability and intent to hold to maturity are classified as held-to-maturity. The remaining fixed maturities, which may be sold prior to maturity to support our investment strategies, such as in response to changes in interest rates and the yield curve or to maximize after-tax returns, are classified as available-for-sale. Fixed maturities classified as held-to-maturity are carried at amortized cost while fixed maturities classified as available-for-sale are carried at market value. At December 31, 2003, 2% of the fixed maturity portfolio was classified as held-to-maturity compared with 5% at December 31, 2002 and 8% at December 31, 2001.

Changes in the general interest rate environment affect the returns available on new fixed maturity investments. While a rising interest rate environment enhances the returns available, it reduces the market value of existing fixed maturity investments and thus the availability of gains on disposition. A decline in interest rates reduces the returns available on new investments but increases the market value of existing investments, creating the opportunity for realized investment gains on disposition.

The unrealized appreciation before tax of investments carried at market value, which includes fixed maturities classified as available-for-sale and equity securities, was $1,036 million, $901 million and $389 million at December 31, 2003, 2002 and 2001, respectively. Such unrealized appreciation is reflected in a separate component of other comprehensive income, net of applicable deferred income tax.

The unrealized market appreciation before tax of those fixed maturities carried at amortized cost was $35 million, $56 million and $64 million at December 31, 2003, 2002 and 2001, respectively. Such unrealized appreciation was not reflected in the consolidated financial statements.

Changes in unrealized market appreciation or depreciation of fixed maturities were due primarily to fluctuations in interest rates.

Effective January 1, 2002, the Corporation adopted Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets. SFAS No. 142 may not be applied retroactively to financial statements of prior periods. Under SFAS No. 142, goodwill is no longer amortized. Goodwill amortization was approximately $20 million in 2001.

Effective January 1, 2003, the Corporation adopted the fair value method of accounting for stock-based employee compensation plans, which is the method of accounting defined in SFAS No. 123, Accounting for Stock-Based Compensation. Under the fair value method of accounting, compensation cost is measured based on the fair value of the award at the grant date and recognized over the service

period. Prior period financial statements were not restated. The adoption of the fair value method of accounting for stock-based employee compensation plans resulted in a reduction in net income of approximately $46 million in 2003.

In the fourth quarter of 2003, the Corporation adopted Financial Accounting Standards Board Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities, an interpretation of Accounting Research Bulletin No. 51. FIN 46 requires that a variable interest entity be consolidated by its primary beneficiary. As a result of its variable interests in a real estate partnership, our real estate subsidiary is the primary beneficiary of the partnership. We applied FIN 46 by retroactively restating prior year financial statements with a cumulative-effect adjustment as of the beginning of the first year restated. The effect of the restatement on previously reported December 31, 2000 shareholders’ equity was a decrease of $33.5 million. The effect on net income for 2001 and 2002, as previously reported, and on net income for 2003 was immaterial.

These changes in accounting are discussed further in Note (2) of the Notes to Consolidated Financial Statements.

Market risk represents the potential for loss due to adverse changes in the fair value of financial instruments. Our primary exposure to market risks relates to our investment portfolio, which is sensitive to changes in interest rates and, to a lesser extent, credit quality, prepayment, foreign currency exchange rates and equity prices. We also have exposure to market risks through CFS’s financial products portfolio and our debt obligations. Analytical tools and monitoring systems are in place to assess each of these elements of market risk.

Interest rate risk is the price sensitivity of a security that promises a fixed return to changes in interest rates. Changes in market interest rates directly affect the market value of our fixed income securities. We view the potential changes in price of our fixed income investments within the overall context of asset and liability management. Our actuaries estimate the payout pattern of our liabilities, primarily our property and casualty loss reserves, to determine their duration, which is the present value of the weighted average payments expressed in years. We set duration targets for our fixed income investment portfolios after consideration of the duration of these liabilities and other factors, which we believe mitigates the overall effect of interest rate risk for the Corporation.

The following table provides information about our fixed maturity investments, which are sensitive to changes in interest rates. The table presents cash flows of principal amounts and related weighted average interest rates by expected maturity dates at December 31, 2003 and 2002. The cash

We have consistently invested in high quality marketable securities. As a result, we believe that we have minimal credit quality risk. Approximately 70% of the taxable bonds in our portfolio are issued by the U.S. Treasury or U.S. government agencies or rated AA or better by Moody’s or Standard and Poor’s. Of the tax-exempt bonds, more than 90% are rated AA or better with about 65% rated AAA. Approximately 2% of our bond portfolio is below investment grade. Our taxable bonds have an average maturity of five years, while our tax-exempt bonds mature on average in nine years.

Prepayment risk refers to the changes in prepayment patterns related to decreases and increases in interest rates that can either shorten or lengthen the expected timing of the principal repayments and thus the average life of a security, potentially reducing or increasing its effective yield. Such risk exists primarily within our portfolio of mortgage-backed securities. We monitor such risk regularly and invest primarily in those classes of mortgage-backed securities that are less subject to prepayment risk.

Mortgage-backed securities comprised 32% and 34% of our taxable bond portfolio at year-end 2003 and 2002, respectively. About 68% of our mortgage-backed securities holdings at December 31, 2003 related to residential mortgages consisting of government agency pass-through securities, government agency collateralized mortgage obligations (CMOs) and AAA rated non-agency CMOs backed by government agency collateral or single family home mortgages. The majority of the CMOs are actively

traded in liquid markets and market value information is readily available from broker/dealers. An additional 17% of our mortgage-backed securities were call protected AAA rated commercial mortgage-backed securities. The remaining mortgage-backed holdings were in investment grade commercial mortgage-backed securities.

Foreign currency risk is the sensitivity to foreign exchange rate fluctuations of the market value and investment income related to foreign currency denominated financial instruments. The functional currency of our foreign operations is generally the currency of the local operating environment since business is primarily transacted in such local currency. We reduce the risks relating to currency fluctuations by maintaining investments in those foreign currencies in which our property and casualty subsidiaries have loss reserves and other liabilities. Such investments have characteristics similar to our liabilities in those currencies. At December 31, 2003, the property and casualty subsidiaries held non-U.S. investments of $3.7 billion supporting their international operations. These investments have quality and maturity characteristics similar to our domestic portfolio. The principal currencies creating foreign exchange rate risk for the property and casualty subsidiaries are the British pound sterling, the euro and the Canadian dollar. The following table provides information about those fixed maturity investments that are denominated in these currencies. The table presents cash flows of principal amounts in U.S. dollar equivalents by expected maturity dates at December 31, 2003 and 2002. Actual cash flows could differ from the expected amounts.

Equity price risk is the potential loss in market value of our equity securities resulting from adverse changes in stock prices. In general, equities have more year-to-year price variability than intermediate term high grade bonds. However, returns over longer time frames have been consistently higher. Our publicly traded equity securities are high quality, diversified across industries and readily marketable. Our portfolio also includes alternative investments, primarily investment partnerships. These investments by their nature are less liquid than other investments. We actively manage our market risk by allocating a comparatively small amount of funds to alternative investments, performing extensive research prior to investing in a new investment and monitoring the performance of the entities in which we have invested. A hypothetical decrease of 10% in the market price of each of the equity securities held at December 31, 2003 and 2002 would have resulted in a decrease of $151 million and $99 million, respectively, in the fair value of the equity securities portfolio.

All of the above risks are monitored on an ongoing basis. A combination of in-house systems and proprietary models and externally licensed software are used to analyze individual securities as well as each portfolio. These tools provide the portfolio managers with information to assist them in the evaluation of the market risks of the portfolio.

The Corporation, through CFS’s business, assumed exposure to credit risk through portfolio credit default swaps. In a typical portfolio credit default swap, the occurrence of certain defined credit events related to referenced entities within a specified portfolio will result in a deterioration of the subordination. When losses related to cumulative credit events exceed the subordination, the contract requires CFS to make payment to its counterparty. These obligations are guaranteed by the Corporation. As discussed in the Chubb Financial Solutions section of MD&A, we have exited this business and are running off CFS’s remaining portfolio credit default swaps.

Valuation models are used to estimate the fair value of our obligation in each credit default swap. Within these models, credit spreads are a critical input used to estimate the probability of the occurrence of credit events. The fair value of a portfolio credit default swap is also a function of the financial ratings of referenced asset-backed securities, actual credit events reducing subordination, credit correlation within a portfolio, anticipated recovery rates related to potential defaults and changes in interest rates.

At December 31, 2003, our in-force corporate portfolio credit default swaps have final maturities within two to nine years, with an expected average remaining life of four years. Our in-force asset-backed portfolio credit default swaps have final maturities that range from 2011 to 2041. However, due to amortization of the underlying assets and other terms related to those swaps, the expected average remaining life is seven years.

The following table provides information about our portfolio credit default swaps by maturity, including the fair value of future obligations:

CFS also assumed exposure to credit risk through the principal and interest guarantee entered into in 2003 that guarantees to the counterparty the payment of any principal or interest amount due and not paid with respect to a group of referenced securities. The notional exposure under the guarantee is $2.3 billion. However, CFS’s maximum payment obligation is limited to $500 million. At the inception of the agreement, CFS established a liability of $186 million for the estimated fair value of the guarantee.

We also have interest rate risk on our debt obligations. The following table provides information about our long term debt obligations and related interest rate swap at December 31, 2003. For debt obligations, the table presents expected cash flow of principal amounts and related weighted average

Consolidated financial statements of the Corporation at December 31, 2003 and 2002 and for each of the three years in the period ended December 31, 2003 and the report of independent auditors thereon and the Corporation’s unaudited quarterly financial data for the two-year period ended December 31, 2003 are listed in Item 15(a) of this report.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

As of December 31, 2003, an evaluation of the effectiveness of the design and operation of the Corporation’s disclosure controls and procedures was performed under the supervision and with the participation of the Corporation’s management, including the chief executive officer and chief financial officer. Based on that evaluation, the chief executive officer and chief financial officer concluded that the Corporation’s disclosure controls and procedures were effective as of the evaluation date.

During the three month period ended December 31, 2003, there were no changes in internal control over financial reporting that have materially affected, or are reasonably likely to affect, the Corporation’s internal control over financial reporting.

In accordance with Section 10A(i)(2) of the Securities Exchange Act of 1934, as amended by Section 202 of the Sarbanes-Oxley Act of 2002, the Corporation is required to disclose the approval by the Audit Committee of the Board of Directors of non-audit services to be performed by Ernst & Young LLP, the Corporation’s independent auditors. Non-audit services are services other than those provided in connection with an audit or review of the financial statements.

	By	/s/ JOHN D. FINNEGAN



	(John D. Finnegan Chairman, President and
	Chief Executive Officer)

Pursuant to the requirements of the Securities Exchange Act of 1934, this report has been signed below by the following persons on behalf of the registrant and in the capacities and on the dates indicated:

Management is responsible for the integrity of the financial information included in this annual report and for ascertaining that such information presents fairly the financial position and operating results of the Corporation. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States. Such statements include informed estimates and judgments of management for those transactions that are not yet complete. Financial information presented elsewhere in this annual report is consistent with that in the financial statements.

The accounting systems and internal accounting controls of the Corporation are designed to provide reasonable assurance that assets are safeguarded against losses from unauthorized use or disposition, that transactions are executed in accordance with management’s authorization and that the financial records are reliable for preparing financial statements and maintaining accountability for assets. Qualified personnel throughout the organization maintain and monitor these internal accounting controls on an ongoing basis. In addition, the Corporation’s Internal Audit Department systematically reviews these controls, evaluates their adequacy and effectiveness and reports thereon.

The Audit Committee of the Board of Directors engages Ernst & Young LLP, on behalf of the Corporation, as independent auditors to audit the Corporation’s financial statements and express their opinion thereon. They have full access to each member of management in conducting their audits. Such audits are conducted in accordance with auditing standards generally accepted in the United States and include a review and evaluation of the system of internal accounting controls, tests of the accounting records and other auditing procedures they consider necessary to express their opinion on the consolidated financial statements.

The Corporation’s accounting policies and internal controls are under the general oversight of the Board of Directors acting through its Audit Committee. This Committee is composed entirely of Directors who are not officers or employees of the Corporation. The Committee meets regularly with management, the internal auditors and the independent auditors to review the accounting principles and practices employed by the Corporation and to discuss auditing, internal control and financial reporting matters. Both the internal and independent auditors have, at all times, unrestricted access to the Audit Committee, without members of management present, to discuss the results of their audits, their evaluations of the adequacy of the Corporation’s internal accounting controls and the quality of the Corporation’s financial reporting, and any other matter that they believe should be brought to the attention of the Committee.

All other schedules are omitted since the required information is not present or is not present in amounts sufficient to require submission of the schedule, or because the information required is included in the financial statements and notes thereto.

We have audited the accompanying consolidated balance sheets of The Chubb Corporation as of December 31, 2003 and 2002, and the related consolidated statements of income, shareholders’ equity, cash flows and comprehensive income for each of the three years in the period ended December 31, 2003. Our audits also included the financial statement schedules listed in the index at Item 15(a). These financial statements and schedules are the responsibility of the Corporation’s management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of The Chubb Corporation at December 31, 2003 and 2002, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2003, in conformity with accounting principles generally accepted in the United States. Also, in our opinion, the related financial statement schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein.

As discussed in Note (2) to the financial statements, in 2003 the Corporation changed their method of accounting for stock-based employee compensation and adopted FASB Interpretation No. 46, Consolidation of Variable Interest Entities, an interpretation of Accounting Research Bulletin No. 51.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and include the accounts of The Chubb Corporation (Chubb) and its subsidiaries (collectively, the Corporation). Significant intercompany transactions have been eliminated in consolidation.

The consolidated financial statements include amounts based on informed estimates and judgments of management for those transactions that are not yet complete. Such estimates and judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Chubb is a holding company with subsidiaries principally engaged in the property and casualty insurance business. The property and casualty insurance subsidiaries (the P&C Group) underwrite most lines of property and casualty insurance in the United States, Canada, Europe, Australia and parts of Latin America and Asia. The geographic distribution of property and casualty business in the United States is broad with a particularly strong market presence in the Northeast.

Chubb Financial Solutions (CFS) was organized in 2000 to develop and provide customized risk-financing services through both the capital and insurance markets. CFS’s non-insurance business was primarily structured credit derivatives, principally as a counterparty in portfolio credit default swap contracts. In the second quarter of 2003, the Corporation implemented a plan to exit the credit derivatives business and is running off the financial products portfolio of CFS.

In 2003, the Corporation adopted Financial Accounting Standards Board (FASB) Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities, an interpretation of Accounting Research Bulletin No. 51. As required under FIN 46, the Corporation has consolidated a real estate partnership in which its real estate subsidiary, Bellemead Development Corporation (Bellemead), is the primary beneficiary. The accounting change has been retroactively applied; accordingly, prior year financial statements have been restated to reflect the change in accounting described in Note (2)(c).

Certain amounts in the consolidated financial statements for prior years have been reclassified to conform with the 2003 presentation.

Short term investments, which have an original maturity of one year or less, are carried at amortized cost.

Fixed maturities, which include bonds and redeemable preferred stocks, are purchased to support the investment strategies of the Corporation. These strategies are developed based on many factors including rate of return, maturity, credit risk, tax considerations and regulatory requirements. Fixed maturities that may be sold prior to maturity to support the investment strategies of the Corporation are classified as available-for-sale and carried at market value as of the balance sheet date. Those fixed maturities that the Corporation has the ability and positive intent to hold to maturity are classified as held-to-maturity and carried at amortized cost.

Premiums and discounts arising from the purchase of mortgage-backed securities are amortized using the interest method over the estimated remaining term of the securities, adjusted for anticipated prepayments.

Equity securities include common stocks, non-redeemable preferred stocks and alternative investments, primarily investment partnerships. Common and non-redeemable preferred stocks are carried at market value as of the balance sheet date. Investment partnerships are carried at the Corporation’s equity in the estimated market value of the investments held by the partnerships.

Unrealized appreciation or depreciation of investments carried at market value is excluded from net income and credited or charged, net of applicable deferred income tax, directly to a separate component of comprehensive income.

Realized gains and losses on the sale of investments are determined on the basis of the cost of the specific investments sold and are credited or charged to income. When the market value of any investment is lower than its cost, an assessment is made to determine if the decline is other than temporary. If the decline is deemed to be other than temporary, the investment is written down to market value and the amount of the writedown is charged to income as a realized investment loss. The market value of the investment becomes its new cost basis.

The P&C Group engages in securities lending whereby certain securities from their portfolios are loaned to other institutions for short periods of time. Cash collateral obtained from the borrower, equal to the market value of the loaned securities plus accrued interest, is deposited with a lending agent and invested by the lending agent in accordance with the Corporation’s guidelines to generate additional income, which the P&C Group shares with the lending agent. The P&C Group maintains full ownership rights to the securities loaned and continues to earn interest on them. Accordingly, such securities are included in invested assets. The securities lending collateral is recognized as an asset with a corresponding liability for the obligation to return the collateral.

Premiums are earned on a monthly pro rata basis over the terms of the policies and include estimates of audit premiums and premiums on retrospectively rated policies. Assumed reinsurance premiums are earned over the terms of the reinsurance contracts. Unearned premiums represent the portion of direct and assumed premiums written applicable to the unexpired terms of the policies and reinsurance contracts in force.

Ceded reinsurance premiums are charged to income over the terms of the reinsurance contracts. Prepaid reinsurance premiums represent the portion of premiums ceded to reinsurers applicable to the unexpired terms of the reinsurance contracts in force.

Reinsurance reinstatement premiums are recognized in the same period as the loss event that gave rise to the reinstatement premiums.

Acquisition costs that vary with and are primarily related to the production of business are deferred and amortized over the period in which the related premiums are earned. Such costs include commissions, premium taxes and certain other underwriting and policy issuance costs. Commissions received related to reinsurance premiums ceded are considered in determining net acquisition costs eligible for deferral. Deferred policy acquisition costs are reviewed to determine that they do not exceed recoverable amounts. Anticipated investment income is considered in the determination of the recoverability of deferred policy acquisition costs.

Liabilities for unpaid losses and loss expenses include the accumulation of individual case estimates for claims reported as well as estimates of incurred but not reported claims and estimates of loss settlement expenses, less estimates of anticipated salvage and subrogation recoveries.

Reinsurance recoverable on unpaid losses and loss expenses represent estimates of the portion of such liabilities that will be recovered from reinsurers. Amounts recoverable from reinsurers are recognized as assets at the same time and in a manner consistent with the unpaid losses associated with the reinsured policies. A provision for estimated uncollectible reinsurance is recorded based on an evaluation of balances due from reinsurers and other available information.

Estimates are based upon past loss experience modified for current trends as well as prevailing economic, legal and social conditions. Such estimates are continually reviewed and updated. Any changes in estimates are reflected in operating results in the period in which the estimates are changed.

Credit derivatives, principally portfolio credit default swaps, are carried at estimated fair value as of the balance sheet date. Changes in fair value are recognized in income in the period of the change and are included in other revenues.

A liability for the estimated fair value of a principal and interest guarantee was recognized at the inception of the guarantee contract. Due to the nature of the guarantee, the liability will be reduced only upon either expiration or settlement of the guarantee.

Assets and liabilities related to the credit derivatives and the guarantee are included in other assets and other liabilities.

Real estate properties are carried at cost less accumulated depreciation and any writedowns for impairment. Real estate taxes, interest and other carrying costs incurred prior to completion of the assets for their intended use are capitalized. Also, costs incurred during the initial leasing of income producing properties are capitalized until the project is substantially complete, subject to a maximum time period subsequent to completion of major construction activity.

Real estate properties are reviewed for impairment whenever events or circumstances indicate that the carrying value of such properties may not be recoverable. In performing the review for recoverability of carrying value, estimates are made of the future undiscounted cash flows from each of the properties during the period the property will be held and upon its eventual disposition. If the expected future undiscounted cash flows are less than the carrying value of any property, an impairment loss is recognized, resulting in a writedown of the carrying value of the property. Measurement of such impairment is based on the fair value of the property.

Rental revenues are recognized on a straight-line basis over the term of the lease. Profits on land, residential unit and commercial building sales are recognized at closing, subject to compliance with applicable accounting guidelines.

Investment in partially owned company includes the Corporation’s 19% interest in a corporate joint venture, Allied World Assurance Holdings, Ltd. The equity method of accounting is used for this investment.

Goodwill represents the excess of the purchase price over the fair value of net assets of subsidiaries acquired. Prior to 2002, goodwill was amortized using the straight-line method over 26 years. Effective January 1, 2002, goodwill is no longer amortized but rather is tested at least annually for impairment (see Note (2)(a)).

Property and equipment used in operations, including certain costs incurred to develop or obtain computer software for internal use, are capitalized and carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets.

Chubb and its domestic subsidiaries file a consolidated federal income tax return.

Deferred income tax assets and liabilities are recognized for the expected future tax effects attributable to temporary differences between the financial reporting and tax bases of assets and liabilities, based on enacted tax rates and other provisions of tax law. The effect on deferred tax assets and liabilities of a change in tax laws or rates is recognized in income in the period in which such change is enacted. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that all or some portion of the deferred tax assets will not be realized.

The Corporation does not consider the earnings of its foreign subsidiaries to be permanently reinvested. Accordingly, U.S. federal income taxes are accrued on undistributed earnings of foreign subsidiaries.

Prior to 2003, the intrinsic value method of accounting was used for stock-based employee compensation plans. Under the intrinsic value method, compensation cost was measured as the excess, if any, of the quoted market price of the stock at the measurement date over the amount an employee must pay to acquire the stock. Effective January 1, 2003, the Corporation adopted the fair value method of accounting for stock-based employee compensation plans (see Note (2)(b)).

Assets and liabilities relating to foreign operations are translated into U.S. dollars using current exchange rates as of the balance sheet date. Revenues and expenses are translated into U.S. dollars using the average exchange rates during the year.

The functional currency of foreign operations is generally the currency of the local operating environment since business is primarily transacted in such local currency. Translation gains and losses, net of applicable income tax, are excluded from net income and are credited or charged directly to a separate component of comprehensive income.

In the statement of cash flows, short term investments are not considered to be cash equivalents. The effect of changes in foreign exchange rates on cash balances was immaterial.

(a) Effective January 1, 2002, the Corporation adopted Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets. The Statement addresses how intangible assets should be accounted for upon their acquisition and how goodwill and other intangible assets should be accounted for after they have been initially recognized in the financial statements. In accordance with SFAS No. 142, goodwill is no longer amortized but rather is tested at least annually for impairment. SFAS No. 142 may not be applied retroactively to financial statements of prior periods.

The Corporation completed a transitional goodwill impairment test during 2002 and an annual goodwill impairment test during 2002 and 2003. As a result of the tests, management determined that there was no impairment of goodwill.

Adoption of SFAS No. 142 as of January 1, 2001 would have increased net income for 2001 by $19.9 million or $0.11 per basic and diluted share.

(b) Effective January 1, 2003, the Corporation adopted the fair value method of accounting for stock-based employee compensation plans, which is the method of accounting defined in SFAS No. 123, Accounting for Stock-Based Compensation. Under the fair value method of accounting, compensation cost is measured based on the fair value of the award at the grant date and recognized over the service period. The Corporation has elected to use the modified prospective method of transition, as permitted by SFAS No. 148, Accounting for Stock-Based Compensation — Transition and Disclosure. Under this method, stock-based employee compensation cost is recognized from the beginning of 2003 as if the fair value method of accounting had been used to account for all employee awards granted, modified, or settled in years beginning after December 15, 1994. Prior period financial statements were not restated. The adoption of the fair value method of accounting for stock-based employee compensation plans increased compensation cost by $66.2 million for the year ended December 31, 2003, which resulted in a reduction in net income of $46.0 million or $0.25 per basic and diluted share.

The following information illustrates the pro forma effect on net income and earnings per share as if the fair value method of accounting for stock-based employee compensation had been applied retroactively to financial statements of prior periods.

The weighted average fair value of stock options granted during 2003, 2002 and 2001 was $9.71, $19.11 and $18.22, respectively. The fair value of each stock option was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions.

(c) In January 2003, the FASB issued FIN 46 which explains how to identify a variable interest entity and how an enterprise assesses its interests in a variable interest entity to determine whether to consolidate that entity. A variable interest entity is an entity in which the equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support or the equity investors do not have the characteristics of a controlling financial interest. FIN 46 requires that a variable interest entity be consolidated by its primary beneficiary, which is the party that will absorb a majority of the entity’s expected losses, receive a majority of the entity’s expected residual returns, or both.

The provisions of FIN 46 were effective immediately for variable interest entities created after January 31, 2003 and for variable interest entities in which the Corporation obtains an interest after that date. The Corporation has not acquired a material interest in any variable interest entities subsequent to January 31, 2003.

For any variable interest entities in which the Corporation holds a variable interest that it acquired prior to February 1, 2003, the provisions of FIN 46, as revised in December 2003, are effective no later than the quarter ending March 31, 2004. For any such variable interest entity for which the Corporation determines that it is the primary beneficiary, the Corporation should initially measure the assets, liabilities and noncontrolling interests of the entity at their carrying amounts. Any difference between the net amount added to the Corporation’s balance sheet and the amount of any previously recognized interest in the newly consolidated entity should be recognized as the cumulative effect of an accounting change.

Bellemead has a collateralized mortgage note receivable from a real estate partnership in which it does not have an equity interest. The partnership is a variable interest entity. Bellemead has certain lease obligations related to the property held by the partnership. As a result of its variable interests, Bellemead is the primary beneficiary of the partnership. Accordingly, consolidation of the real estate partnership is required under FIN 46.

The Corporation has elected to adopt the provisions of FIN 46 as of December 31, 2003 and has applied FIN 46 by retroactively restating prior year financial statements with a cumulative-effect adjustment as of the beginning of the first year restated. The effect of the restatement on previously reported December 31, 2000 shareholders’ equity was a decrease of $33.5 million. The effect on net income for 2001 and 2002, as previously reported, and on net income for 2003 was immaterial.

There were no other interests in variable interest entities identified that would require consolidation or disclosure.

In November 2001, the Corporation acquired a 19% interest in Allied World Assurance Holdings, Ltd, a newly formed Bermuda-based company, for approximately $250 million. Allied World Assurance was established to underwrite insurance and reinsurance business worldwide.

(a) Insurance losses and loss expenses of the P&C Group include $250 million, $741 million and $61 million in 2003, 2002 and 2001, respectively, related to asbestos and toxic waste claims. The P&C Group’s asbestos and toxic waste related exposure is further discussed in Note (11).

(b) In the fourth quarter of 2001, surety bond losses of $220 million, net of reinsurance, were recognized related to the bankruptcy of Enron Corp. The surety losses represented the maximum exposure of the P&C Group relating to bonds issued to various obligees in connection with Enron commitments. Certain of these bonds were the subject of litigation. As of the end of 2002, the litigation was settled, resulting in an $88 million reduction in surety loss reserves. In 2003, the sale of a bankruptcy claim against various Enron entities resulted in a $17 million surety recovery.

(c) In the third quarter of 2001, net costs of $645 million were incurred related to the September 11 attack in the United States. The net costs consisted of estimated net losses and loss expenses of $665 million less net reinsurance reinstatement premium revenue of $30 million plus a $10 million charge for the Corporation’s share of the losses publicly estimated by Hiscox plc, a U.K. insurer in which the Corporation had a 28% interest during 2001.

Gross losses and loss expenses of the P&C Group from the September 11 attack are estimated at about $3.2 billion. Most of the claims were from property exposure and business interruption losses. There were also significant workers’ compensation losses. The net losses and loss expenses of $665 million were significantly lower than the gross amount due to various reinsurance agreements. The property exposures were protected by facultative reinsurance, property per risk treaties that limited the net loss per risk, and property catastrophe treaties. Workers’ compensation losses were protected by a casualty catastrophe treaty and a casualty clash treaty.

It is possible that the estimate of ultimate losses related to the September 11 attack may change in the future, and that the change in estimate could have a material effect on the Corporation’s results of operations. However, management does not expect that any such change would have a material effect on the Corporation’s financial condition or liquidity.

In the ordinary course of business, the P&C Group assumes and cedes reinsurance with other insurance companies and are members of various pools and associations. Reinsurance is ceded to provide greater diversification of risk and to limit the maximum net loss potential arising from large or concentrated risks. A large portion of the reinsurance ceded by the P&C Group is effected under contracts known as treaties and in some instances by negotiation on individual risks. Certain of these arrangements consist of excess of loss and catastrophe contracts that protect against losses over stipulated amounts arising from any one occurrence or event.

Ceded reinsurance contracts do not relieve the insurance subsidiaries from their primary obligation to their policyholders. Thus, a credit exposure exists with respect to reinsurance ceded to the extent that any reinsurer is unable to meet the obligations assumed under the reinsurance contracts. The Corporation evaluates the financial condition of its reinsurers on an ongoing basis to minimize its exposure to losses from reinsurer insolvencies.

Premiums earned and insurance losses and loss expenses are reported net of reinsurance in the consolidated statements of income.

The effect of reinsurance on the premiums written and earned of the P&C Group was as follows:

Assumed reinsurance premiums earned and written and ceded reinsurance premiums earned and written for 2001 included reinstatement premiums of $95.0 million and $65.0 million, respectively, related to the September 11 attack.

Reinsurance recoveries by the P&C Group that have been deducted from insurance losses and loss expenses were $767.0 million, $1,216.1 million and $3,367.4 million in 2003, 2002 and 2001, respectively. The 2002 and 2001 amounts included recoveries of $177.1 million and $2,385.2 million, respectively, related to the September 11 attack.

(a) The amortized cost and estimated market value of fixed maturities were as follows:

The amortized cost and estimated market value of fixed maturities at December 31, 2003 by contractual maturity were as follows:

Actual maturities could differ from contractual maturities because borrowers may have the right to call or prepay obligations.

(b) The components of unrealized appreciation or depreciation of investments carried at market value were as follows:

At December 31, 2003, equity securities and fixed maturities with an aggregate market value of $228.7 million had been in an unrealized loss position for a period greater than 12 months. The aggregate amount of unrealized depreciation on such invested assets was $11.7 million.

The change in unrealized appreciation or depreciation of investments carried at market value was as follows:

The unrealized appreciation of fixed maturities carried at amortized cost is not reflected in the financial statements. The change in unrealized appreciation of fixed maturities carried at amortized cost was a decrease of $20.6 million, $8.2 million and $4.6 million for the years ended December 31, 2003, 2002 and 2001, respectively.

Policy acquisition costs deferred and the related amortization charged against income were as follows:

Depreciation expense related to income producing properties was $4.1 million, $4.5 million and $4.2 million for 2003, 2002 and 2001, respectively.

Depreciation expense related to property and equipment was $103.9 million, $98.6 million and $90.9 million for 2003, 2002 and 2001, respectively.

The mortgages are obligations of Bellemead and are payable in varying amounts monthly through 2010. At December 31, 2003, the interest rate for the mortgages payable approximated 8.5%.

The 6 7/8% notes were obligations of Chubb Capital Corporation (Chubb Capital), a wholly owned subsidiary of Chubb, and were paid when due.

The Corporation filed a shelf registration statement which the Securities and Exchange Commission declared effective in June 2003, under which up to $2.5 billion of various types of securities may be issued. At December 31, 2003, approximately $650 million remained under the shelf.

In March 2003, Chubb issued $225 million of unsecured 3.95% notes due April 1, 2008 and $275 million of unsecured 5.2% notes due April 1, 2013, the aggregate net proceeds from which were $495 million.

In June 2003, Chubb issued $460 million of unsecured 2.25% senior notes due August 16, 2008 and 18.4 million purchase contracts to purchase the Corporation’s common stock. The notes and purchase contracts were issued together in the form of 7% equity units. The net proceeds were $446 million. Each equity unit initially represents one purchase contract and $25 principal amount of senior notes. The notes are pledged by the holders to secure their obligations under the purchase contracts. Chubb will make quarterly interest payments to the holders of the notes initially at a rate of 2.25% per year.

In November 2002, Chubb issued $600 million of unsecured 4% senior notes due November 16, 2007 and 24 million mandatorily exercisable warrants to purchase the Corporation’s common stock. The notes and warrants were issued together in the form of 7% equity units. The net proceeds were $582 million. Each equity unit initially represents one warrant and $25 principal amount of senior notes. The notes are pledged by the holders to secure their obligations under the warrants. Chubb will make quarterly interest payments to the holders of the notes initially at a rate of 4% per year.

The 2.25% notes and the 4% notes will be remarketed in May 2006 and August 2005, respectively. At the time the respective notes are remarketed, the remarketing agent will have the ability to reset the interest rate on the notes in order to generate sufficient remarketing proceeds to satisfy the holder’s obligation under the purchase contract or warrant. If the senior notes are not successfully remarketed, the Corporation will exercise its rights as a secured party to obtain and extinguish the notes and deliver its common stock to the holders pursuant to the purchase contracts or warrants. The purchase contracts and warrants are further described in Note (20)(c).

The 6.15% notes, the 6% notes, the 6.6% debentures and the 6.8% debentures are all unsecured obligations of Chubb.

The 7 1/8% notes are obligations of Chubb Executive Risk Inc., a wholly owned subsidiary, and are fully and unconditionally guaranteed by Chubb.

Executive Risk Capital Trust, wholly owned by Chubb Executive Risk, has outstanding $125 million of 8.675% capital securities. The Trust in turn used the proceeds from the issuance of the capital securities to acquire $125 million of Chubb Executive Risk 8.675% junior subordinated deferrable interest debentures due February 1, 2027. The sole assets of the Trust are the debentures. The debentures and the related income effects are eliminated in the consolidated financial statements. The capital securities are subject to mandatory redemption on February 1, 2027, upon repayment of the debentures. The capital securities are also subject to mandatory redemption in certain other specified circumstances beginning in 2007 at a redemption price that includes a make whole premium through 2017 and at par thereafter. Chubb Executive Risk has the right, at any time, to defer payments of interest on the debentures and hence distributions on the capital securities for a period not exceeding ten consecutive semi-annual periods up to the maturity dates of the respective securities. During any such period, interest will continue to accrue and Chubb Executive Risk may not declare or pay any dividends. The capital securities are unconditionally and on a subordinated basis guaranteed by Chubb.

Chubb is a party to a cancelable interest rate swap agreement with a notional amount of $125.0 million that replaces the fixed rate of the capital securities with the 3-month LIBOR rate plus 204 basis points. The swap agreement provides only for the exchange of interest on the notional amount. The interest rate swap matures in February 2027. The fair value of the swap is included in other assets, offset by a corresponding increase to long term debt.

The amounts of long term debt due annually during the five years subsequent to December 31, 2003 are as follows:

(b) Interest costs of $130.1 million, $83.8 million and $55.0 million were incurred in 2003, 2002 and 2001, respectively. Interest paid was $122.2 million, $85.0 million and $55.5 million in 2003, 2002 and 2001, respectively.

(c) The Corporation has two credit agreements with a group of banks that provide for unsecured borrowings of up to $500 million in the aggregate. The $250 million short term revolving credit facility, which was to have terminated on June 27, 2003, was extended to June 24, 2004, and may be renewed or replaced. The $250 million medium term revolving credit facility terminates on June 28, 2007. On the respective termination dates for these agreements, any loans then outstanding become payable. There have been no borrowings under these agreements. Various interest rate options are available to the Corporation, all of which are based on market interest rates. The Corporation pays a fee to have these credit facilities available. Unused credit facilities are available for general corporate purposes and to support Chubb Capital’s commercial paper borrowing arrangement.

The process of establishing loss reserves is complex and imprecise as it must take into consideration many variables that are subject to the outcome of future events. As a result, subjective judgments as to the P&C Group’s ultimate exposure to losses are an integral component of the loss reserving process.

Most of the P&C Group’s loss reserves relate to long tail liability classes of business. For many liability claims significant periods of time, ranging up to several years or more, may elapse between the occurrence of the loss, the reporting of the loss and the settlement of the claim. The longer the time span between the incidence of a loss and the settlement of the claim, the more the ultimate settlement amount can vary.

The inherent uncertainty in the process of establishing loss reserves arises from a number of factors. These factors include, but are not limited to, changes in the inflation rate for goods and services related to covered damages such as medical care and home repair costs; changes in the judicial environment regarding the interpretation of policy provisions relating to the determination of coverage; changes in the general attitude of juries in the determination of liability and damages; changes in the estimates of the number and/or severity of claims that have been incurred but not reported as of the date of the financial statements; and changes in the P&C Group’s underwriting standards and/ or claim handling procedures.

In addition, the uncertain effects of emerging or potential claims and coverage issues must be taken into consideration. These issues can have a negative effect on loss reserves by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims. As a result of such issues, the uncertainties inherent in estimating ultimate claim costs on the basis of past experience have become increasingly unpredictable, further complicating the already complex loss reserving process. The future impact of these issues and other unforeseen emerging or potential claims and coverage issues is extremely hard to predict and could materially adversely affect the adequacy of the P&C Group’s loss reserves.

The uncertainties relating to asbestos and toxic waste claims on insurance policies written many years ago are exacerbated by inconsistent court decisions as well as judicial interpretations and legislative actions that in some cases have tended to broaden coverage beyond the original intent of such policies and in others have expanded theories of liability. The industry as a whole is engaged in extensive litigation over these coverage and liability issues and is thus confronted with a continuing uncertainty in its efforts to quantify these exposures.

Asbestos remains the most significant and difficult mass tort for the insurance industry in terms of claims volume and dollar exposure. Asbestos claims relate primarily to bodily injuries asserted by those who came in contact with asbestos or products containing asbestos. Early court cases established the “continuous trigger” theory with respect to insurance coverage. Under this theory, insurance coverage is deemed to be triggered from the time a claimant is first exposed to asbestos until the manifestation of any disease. This interpretation of a policy trigger can involve insurance companies over many years and increases their exposure to liability.

The plaintiffs’ bar continues to solicit new claimants through extensive advertising and through asbestos medical screenings. Litigation is then initiated even though many of the claimants do not show any signs of asbestos-related disease. Thus, new asbestos claims and new exposures on existing claims have continued unabated despite the fact that usage of asbestos has declined since the mid-1970’s. Based on published projections, it is expected that the P&C Group will continue receiving asbestos claims at the current rate for at least the next several years.

The P&C Group’s most significant individual asbestos exposures involve product liability on the part of “traditional” defendants who manufactured, distributed or installed asbestos products for whom the P&C Group wrote excess liability and/or general liability coverages. While these insureds are relatively few in number, such exposure has increased in recent years due to the increased volume of claims, the erosion of much of the underlying limits and the bankruptcies of target defendants.

Other asbestos exposures involve product and non-product liability on the part of “peripheral” defendants, including a mix of manufacturers, distributors and installers of certain products that contain asbestos in small quantities and owners of properties on which asbestos exists. Generally, these insureds are named defendants on a regional rather than a nationwide basis. As the financial resources of traditional asbestos defendants have been depleted, plaintiffs are targeting these viable peripheral parties with greater frequency and, in many cases, for larger awards.

In establishing asbestos reserves, the exposure presented by each insured is evaluated. As part of this evaluation, consideration is given to the available insurance coverage; limits and deductibles; the jurisdictions involved; past settlement values of similar claims; the potential role of other insurance, particularly underlying coverage below excess liability policies; and applicable coverage defenses, including asbestos exclusions.

Significant uncertainty remains as to the ultimate liability of the P&C Group relating to asbestos related claims. This uncertainty is due to such factors as the long latency period between asbestos exposure and disease manifestation and the resulting potential for involvement of multiple policy periods for individual claims as well as the increase in the volume of claims by unimpaired plaintiffs and the increase in claims filed under the non-aggregate premises or operations section of general liability policies. There is also the possibility, however remote, of federal legislation that would address the asbestos problem.

Toxic waste claims relate primarily to pollution and related cleanup costs. The P&C Group’s insureds have two potential areas of exposure, hazardous waste dump sites and pollution at the insured site primarily from underground storage tanks and manufacturing processes.

Under the federal “Superfund” law and similar state statutes, when potentially responsible parties (PRPs) fail to handle the clean-up at a hazardous waste site, regulators have the work done and then attempt to establish legal liability against the PRPs. Most sites have multiple PRPs. Most PRPs named to date are parties who have been generators, transporters, past or present landowners or past or present site operators. The PRPs disposed of toxic materials at a waste dump site or transported the materials to the site. Insurance policies issued to PRPs were not intended to cover the clean-up costs of pollution and, in many cases, did not intend to cover the pollution itself.

There is substantial uncertainty involved in estimating the P&C Group’s liabilities related to these claims. First, the liabilities of the claimants are extremely difficult to estimate. At any given site, the allocation of remediation costs among governmental authorities and the PRPs varies greatly depending on a variety of factors. Second, different courts have addressed liability and coverage issues regarding pollution claims and have reached inconsistent conclusions in their interpretation of several issues. These significant uncertainties are not likely to be resolved definitively in the near future.

Uncertainties also remain as to the Superfund law itself. Superfund’s taxing authority expired on December 31, 1995 and has not been re-enacted. At this time, it is not possible to predict the direction that any reforms may take, when they may occur or the effect that any changes may have on the insurance industry.

In establishing toxic waste reserves, the exposure presented by each insured is evaluated. As part of this evaluation, consideration is given to the probable liability, available insurance coverage, past settlement values of similar exposures as well as facts that are unique to each insured.

A reconciliation of the beginning and ending liability for unpaid losses and loss expenses, net of reinsurance recoverable, and a reconciliation of the net liability to the corresponding liability on a gross basis is as follows:

The gross liability for unpaid losses and loss expenses and reinsurance recoverable included $999.3 million and $748.2 million, respectively, at December 31, 2003, $2,062.6 million and $1,557.9 million, respectively, at December 31, 2002, and $2,775.2 million and $2,238.8 million, respectively, at December 31, 2001 related to the September 11 attack.

During 2003, the P&C Group experienced overall unfavorable development of $397.3 million on net unpaid losses and loss expenses established as of the previous year end. This compares with unfavorable one year development of $789.7 million in 2002 and favorable development of $195.5 million in 2001. Such development was reflected in operating results in these respective years.

The unfavorable development in 2003 was due primarily to two factors. First, asbestos loss reserves were strengthened by $250 million. Second, unfavorable development of about $140 million was experienced in the executive protection classes, principally directors and officers liability and errors and omissions liability, as adverse loss trends in recent accident years related to corporate failures and allegations of management misconduct and accounting irregularities more than offset favorable loss experience in older accident years.

The unfavorable development in 2002 was due primarily to strengthening of asbestos and toxic waste loss reserves by $741 million during the year. In addition, unfavorable development of about $100 million was experienced in the homeowners class due to an increase in the severity of water damage and related mold claims. In the executive protection classes, adverse loss trends in the more recent accident years more than offset favorable loss experience in older accident years, resulting in unfavorable development of about $50 million in 2002. Offsetting the unfavorable development somewhat was the $88 million reduction in surety loss reserves related to the Enron settlement.

The favorable development in 2001 was due primarily to favorable loss experience in certain long tail liability coverages, offset in part by losses incurred related to asbestos and toxic waste claims.

Management believes that the aggregate loss reserves of the P&C Group at December 31, 2003 were adequate to cover claims for losses that had occurred, including both those known and those yet to be reported. In establishing such reserves, management considers facts currently known and the present state of the law and coverage litigation. However, given the judicial decisions and legislative actions that have broadened the scope of coverage and expanded theories of liability in the past and the possibilities of similar interpretations in the future, particularly as they relate to asbestos claims and, to a lesser extent, toxic waste claims, additional liabilities may emerge in future periods for amounts in excess of carried reserves. Such increases in estimates could have a material adverse effect on the Corporation’s future operating results. However, management does not expect that any such increases would have a material effect on the Corporation’s consolidated financial condition.

Federal and foreign income taxes paid were $133.9 million, $38.5 million and $53.4 million in 2003, 2002 and 2001, respectively.

(b) The effective income tax rate is different than the statutory federal corporate tax rate. The reasons for the different effective tax rate were as follows:

(c) The tax effects of temporary differences that gave rise to deferred income tax assets and liabilities were as follows:

Deferred income tax assets are established related to the expected future U.S. tax benefit of losses and foreign taxes incurred by the Corporation’s foreign subsidiaries. Realization of these deferred tax assets depends on the ability to generate sufficient taxable income in future periods in the appropriate taxing jurisdictions. A valuation allowance of $40.0 million was established at December 31, 2002 to reflect management’s assessment that the realization of a portion of the deferred tax assets was uncertain due to the inability of a foreign subsidiary to generate sufficient taxable income in the near term. This foreign subsidiary was profitable in 2003, which reduced the deferred tax assets related to the expected future U.S. tax benefit of losses incurred by the subsidiary. Although realization of the remaining deferred tax assets is not assured, management concluded that it is more likely than not that the foreign subsidiary will generate sufficient taxable income in the near term to realize such deferred tax assets. Accordingly, the valuation allowance was eliminated at December 31, 2003.

(a) The Corporation has several non-contributory defined benefit pension plans covering substantially all employees. Prior to 2001, benefits were generally based on an employee’s years of service and average compensation during the last five years of employment. Effective January 1, 2001, the Corporation changed the formula for providing pension benefits from the final average pay formula to a cash balance formula, which credits employees semi-annually with an amount equal to a percentage of eligible compensation based on age and years of service as well as an interest credit based on individual account balances. Employees hired prior to 2001 will generally be eligible to receive vested benefits based on the higher of the final average pay or cash balance formulas.

The Corporation’s funding policy is to contribute amounts that meet regulatory requirements plus additional amounts determined by management based on actuarial valuations, current market conditions and other factors. This may result in no contribution being made in a particular year.

The Corporation also provides certain other postretirement benefits, principally health care and life insurance, to retired employees and their beneficiaries and covered dependents. Substantially all employees hired before January 1, 1999 may become eligible for these benefits upon retirement if they meet minimum age and years of service requirements. The expected cost of these benefits is accrued during the years that the employees render the necessary service.

The Corporation does not fund these benefits in advance. Benefits are paid as covered expenses are incurred. Health care coverage is contributory. Retiree contributions vary based upon a retiree’s age, type of coverage and years of service with the Corporation. Life insurance coverage is non-contributory.

The Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Act), which was enacted in December 2003, introduces a prescription drug benefit under Medicare as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least equivalent to Medicare. In accordance with FASB Staff Position 106-1, Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003, the Corporation has elected to defer recognizing the effects of the Act on any measures of the benefit obligation and net postretirement benefit cost. Authoritative guidance on the accounting for the federal subsidy is pending and that guidance, when issued, may require the Corporation to restate previously reported information. The Corporation does not expect the impact of the Act to be significant.

The Corporation uses December 31 as the measurement date for its pension and other postretirement benefit plans.

The following table sets forth the plans’ funded status and amounts recognized in the balance sheets:

The Corporation made pension plan contributions of $235.6 million during 2003. No contributions were made during 2002.

Effective January 1, 2003, assumptions related to the estimation of eligible compensation used to project the pension plan benefit obligation were revised, resulting in an increase in the benefit obligation of approximately $85 million.

The accumulated benefit obligation for the pension plans was $733.8 million and $591.7 million at December 31, 2003 and 2002, respectively.

The weighted average assumptions used to determine the benefit obligations were as follows:

The components of net pension and other postretirement benefit costs were as follows:

The weighted average assumptions used to determine net pension and other postretirement benefit costs were as follows:

The Corporation determined the expected long term rate of return on assets by considering the historical returns and the expectations for future returns for each asset class as well as the target allocation of plan assets. The Corporation seeks to obtain a rate of return that over time equals or exceeds the returns of the broad markets in which the plan assets are invested. The target allocation of plan assets is 55% to 65% invested in equity securities, with the remainder invested in fixed maturities. The portfolio is rebalanced periodically, when percentages deviate from this target allocation.

Plan assets are currently invested in a diversified portfolio of predominately U.S. equity securities and fixed maturities. The pension plan weighted average asset allocation was as follows:

The weighted average health care cost trend rate assumptions used to measure the expected cost of medical benefits were as follows:

The health care cost trend rate assumption has a significant effect on the amount of the accumulated other postretirement benefit obligation and the net other postretirement benefit cost reported. To illustrate, a one percent increase or decrease in the trend rate for each year would increase or decrease the accumulated other postretirement benefit obligation at December 31, 2003 by approximately $34 million and the aggregate of the service and interest cost components of net other postretirement benefit cost for the year ended December 31, 2003 by approximately $4 million.

(b) The Corporation has a savings plan, the Capital Accumulation Plan, in which substantially all employees are eligible to participate. Under this plan, the employer makes a matching contribution equal to 100% of each eligible employee’s pre-tax elective contributions, up to 4% of the employee’s eligible compensation. Contributions are invested at the election of the employee in the Corporation’s common stock or in various other investment funds. Employer contributions of $23.2 million, $20.3 million and $18.6 million were charged against income in 2003, 2002 and 2001, respectively.

(a) The Long-Term Stock Incentive Plan (the Plan) provides for the granting of stock options, performance shares, restricted stock and other stock-based awards to key employees. The maximum number of shares of the Corporation’s common stock in respect to which stock-based awards may be granted under the Plan is 13,000,000. At December 31, 2003, 1,844,000 shares were available for grant under the Plan.

Stock options are granted at exercise prices not less than the fair market value of the Corporation’s common stock on the date of grant. The terms and conditions upon which options become exercisable may vary among grants. The options generally become exercisable over the two year period following the date of grant. Options expire no later than ten years from the date of grant.

Performance share awards are based on the achievement of various goals over performance cycle periods and are payable in cash, in shares of the Corporation’s common stock or in a combination of both. Restricted stock awards consist of shares of the Corporation’s common stock granted at no cost to the employees. Shares of restricted stock become outstanding when granted, receive dividends and have voting rights. The shares are subject to forfeiture and to restrictions that limit sale or transfer during the restriction period.

Prior to 2003, the Corporation used the intrinsic value method of accounting for stock-based employee compensation, under which compensation cost was measured as the excess, if any, of the quoted market price of the stock at the measurement date over the amount an employee must pay to acquire the stock. Compensation cost was generally not recognized for stock options granted since the exercise price of such grants was not less than the market price of the underlying stock on the date of grant. However, compensation cost was recognized for certain options that were modified subsequent to their grant. Effective January 1, 2003, the Corporation adopted the fair value method of accounting for stock-based employee compensation using the modified prospective method of transition (see Note (2)(b)). Under the fair value method of accounting for stock-based employee compensation, an amount equal to the fair market value of stock options at the date of grant is expensed over the period that such options become exercisable. The amount charged against income with respect to stock options was $56.0 million, $0.6 million and $9.4 million in 2003, 2002 and 2001, respectively.

The cost of performance share awards, which is based on the fair market value of the awards at the date of grant, is expensed over the performance cycle. An amount equal to the fair market value of restricted share awards at the date of grant is expensed over the restriction period. The aggregate amount charged against income with respect to performance share and restricted stock awards was $17.8 million, $21.6 million and $16.5 million in 2003, 2002 and 2001, respectively.

(b) The Corporation has a Stock Purchase Plan under which substantially all employees are eligible to purchase shares of the Corporation’s common stock based on compensation. At December 31, 2003, there were 1,463,000 shares subscribed, giving employees the right to purchase such shares in June 2004 at a price of $66.36, which was a 10% discount from the market price at the date of grant. Under the fair value method of accounting for stock-based employee compensation, an amount equal to the fair market value of purchase rights at the date of grant is expensed over the two year term of the plan. The amount charged against income with respect to the purchase rights was $10.3 million in 2003. Prior to 2003, compensation cost was not recognized for such rights in accordance with the intrinsic value method of accounting for stock-based employee compensation.

(c) The Corporation has a leveraged Employee Stock Ownership Plan (ESOP) in which substantially all employees are eligible to participate. At its inception in 1989, the ESOP used the proceeds of a $150.0 million loan from Chubb to purchase 7,792,204 newly issued shares of the Corporation’s common stock. The loan is due in September 2004 and bears interest at 9%. The receivable from the ESOP has been recorded as a separate reduction of shareholders’ equity on the consolidated balance sheets. This balance is reduced as repayments are made on the loan principal.

Chubb and its participating subsidiaries make semi-annual contributions to the ESOP. The contributions, together with the dividends on the shares of common stock in the ESOP, are used by the ESOP to make loan interest and principal payments to Chubb. As interest and principal are paid, a portion of the common stock is allocated to eligible employees.

The Corporation uses the cash payment method of recognizing ESOP expense. In 2003, 2002 and 2001, cash contributions to the ESOP of $11 million were charged against income. Dividends on shares of common stock in the ESOP used for debt service were $8 million for 2003, 2002 and 2001.

The number of allocated and unallocated shares held by the ESOP at December 31, 2003 were 4,666,000 and 519,000, respectively. All such shares are considered outstanding for the computation of earnings per share.

The principal business of the Corporation is property and casualty insurance. The profitability of the property and casualty insurance business depends on the results of both underwriting operations and investments, which are viewed as two distinctive operations. The underwriting operations are managed separately from the investment function.

The property and casualty underwriting operations consist of three separate business units: personal insurance, commercial insurance and specialty insurance. The personal segment targets the personal insurance market. The personal classes include automobile, homeowners and other personal coverages. The commercial segment includes those classes of business that are generally available in broad markets and are of a more commodity nature. Commercial classes include multiple peril, casualty, workers’ compensation and property and marine. The specialty segment includes those classes of business that are available in more limited markets since they require specialized underwriting and claim settlement. Specialty classes include executive protection, financial institutions and other specialty coverages.

CFS’s non-insurance business was primarily structured credit derivatives, principally as a counterparty in portfolio credit default swap contracts. The Corporation has implemented a plan to exit the credit derivatives business.

Corporate and other includes investment income earned on corporate invested assets, corporate expenses and the Corporation’s real estate and other non-insurance subsidiaries.

Performance of the property and casualty underwriting segments is based on statutory underwriting results. Under statutory accounting principles, policy acquisition and other underwriting expenses are recognized immediately, not at the time premiums are earned. Statutory underwriting profit is arrived at by reducing premiums earned by losses and loss expenses incurred and statutory underwriting expenses incurred.

Managements uses underwriting results determined in accordance with generally accepted accounting principles (GAAP) 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 is defined as premiums earned less losses and loss expenses incurred and GAAP underwriting expenses incurred.

Investment income performance is based on investment income net of investment expenses, excluding realized investment gains.

Distinct investment portfolios are not maintained for each underwriting segment. Property and casualty invested assets are available for payment of losses and expenses for all classes of business. Therefore, such assets and the related investment income are not allocated to underwriting segments.

Revenues, income before income tax and assets of each operating segment were as follows:

Property and casualty commercial insurance underwriting results for 2003, 2002 and 2001 included net losses of $250 million, $741 million and $61 million, respectively, related to asbestos and toxic waste claims.

Property and casualty specialty insurance underwriting results in 2001 included net surety bond losses of $220 million related to the bankruptcy of Enron Corp. Specialty insurance underwriting results for 2002 and 2003 benefited from reductions in net surety bond losses related to Enron of $88 million and $17 million, respectively.

Property and casualty underwriting results for 2001 included a loss of $635 million from the September 11 attack, comprising $20 million in personal insurance, $103 million in commercial insurance and $512 million in specialty insurance.

Other charges for 2001 included $10 million for the Corporation’s share of the estimated losses of Hiscox from the September 11 attack.

The international business of the property and casualty insurance segment is conducted primarily through subsidiaries that operate solely outside of the United States. Their assets and liabilities are located principally in the countries where the insurance risks are written. International business is also written by branch offices of certain domestic subsidiaries.

(a) CFS participated in derivative financial instruments, principally as a counterparty in portfolio credit default swaps. CFS’s participation in a typical portfolio credit default swap was designed to replicate the performance of a portfolio of corporate securities, a portfolio of asset-backed securities or a specified pool of loans. Chubb has issued unconditional guarantees with respect to all obligations of CFS arising from these transactions.

CFS’s aggregate exposure or retained risk, referred to as notional amounts, from in force derivative financial instruments was as follows:

Notional amounts are used to express the extent of involvement in derivative transactions. The notional amounts are used to calculate the exchange of contractual cash flows and are not necessarily representative of the potential for gain or loss. Notional amounts are not recorded on the balance sheet.

Future obligations with respect to derivative financial instruments are carried at estimated fair value at the balance sheet date and are included in other liabilities. The fair value of future obligations under CFS’s derivative financial instruments was as follows:

CFS has entered into a contract that guarantees to the counterparty the payment of any principal and interest amount due and not paid with respect to a group of referenced securities. The notional exposure under the guarantee is $2.3 billion. However, CFS’s maximum payment obligation is limited to $500 million regardless of the amount of losses that might be incurred on the $2.3 billion portfolio. Moreover, if losses are incurred, CFS’s payment obligations are limited to an extended payment schedule under which no payment would be due until 2010 at the earliest. Chubb has guaranteed CFS’s obligations under the contract. The carried liability at December 31, 2003 related to the guarantee was $186.4 million and was included in other liabilities.

(b) A property and casualty insurance subsidiary issued a reinsurance contract to an insurer that provides financial guarantees on debt obligations. At December 31, 2003, the aggregate principal commitments related to this contract for which the subsidiary was contingently liable amounted to approximately $350 million, net of reinsurance. These commitments expire by 2023.

(c) The P&C Group has exposures related to commercial surety bonds issued on behalf of companies that have experienced deterioration in credit worthiness, including several gas forward purchase surety bonds. In particular, the P&C Group has in force $520 million of gas forward purchase surety bonds with one principal, Aquila, Inc. The P&C Group’s exposure under these bonds will decline over the terms of the bonds, which extend until 2012. These surety bonds, which are uncollateralized, secure Aquila’s obligation to supply gas under long-term forward purchase agreements. Under the terms of these bonds, the P&C Group’s entire obligation to pay could be triggered if Aquila failed to provide gas under its forward purchase contracts or was the subject of a bankruptcy filing. There is currently no reinsurance in place covering the P&C Group’s exposure under these bonds. Aquila continues to perform its obligations under the related gas forward purchase agreements.

(d) The Corporation occupies office facilities under lease agreements that expire at various dates through 2019; such leases are generally renewed or replaced by other leases. In addition, the Corporation leases data processing, office and transportation equipment.

Most leases contain renewal options for increments ranging from five to fifteen years; certain lease agreements provide for rent increases based on price-level factors. All leases are operating leases.

At December 31, 2003, future minimum rental payments required under non-cancellable operating leases were as follows:

(e) The Corporation had certain commitments totaling $394 million at December 31, 2003 to fund limited partnership investments. These capital commitments can be called by the partnerships during the commitment period (on average, 1-4 years) to fund working capital needs or the purchase of new investments.

Basic earnings per common share is based on net income divided by the weighted average number of common shares outstanding during the year. Diluted earnings per share includes the potential dilutive effect of outstanding awards under stock-based employee compensation plans and the purchase contracts and mandatorily exercisable warrants to purchase the Corporation’s common stock.

The following table sets forth the computation of basic and diluted earnings per share:

In 2003, 2002 and 2001, options to purchase 11.7 million shares, 8.5 million shares and 4.0 million shares of common stock with weighted average exercise prices of $70.98 per share, $73.07 per share and $76.27 per share, respectively, were excluded from the computation of diluted earnings per share because the options’ exercise prices were greater than the average market price of the Corporation’s common stock. For additional disclosure regarding the stock-based compensation awards, see Note (14).

The purchase contracts and mandatorily exercisable warrants will have no effect on diluted earnings per share, except during periods when the average market price of a share of the Corporation’s common stock is above the threshold appreciation price of $71.40 and $69.10, respectively. Since the average market price of the Corporation’s common stock during the periods the purchase contracts and warrants were outstanding was below these prices, the shares issuable upon the exercise of the purchase contracts and warrants were excluded from the computation of diluted earnings per share.

Comprehensive income is defined as all changes in shareholders’ equity, except those arising from transactions with shareholders. Comprehensive income includes net income and other comprehensive income, which for the Corporation consists of changes in unrealized appreciation or depreciation of investments carried at market value and changes in foreign currency translation gains or losses.

Fair values of financial instruments are based on quoted market prices where available. Fair values of financial instruments for which quoted market prices are not available are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rates and the estimated amounts and timing of future cash flows. In such instances, the derived fair value estimates cannot be substantiated by comparison to independent markets and are not necessarily indicative of the amounts that would be realized in a current market exchange. Certain financial instruments, particularly insurance contracts, are excluded from fair value disclosure requirements.

The methods and assumptions used to estimate the fair value of financial instruments are as follows:


	(i) The carrying value of short term investments approximates fair value due to the short maturities of these investments.

	(ii) Fair values of fixed maturities with active markets are based on quoted market prices. For fixed maturities that trade in less active markets, fair values are obtained from independent pricing services. Fair values of fixed maturities are principally a function of current interest rates. Care should be used in evaluating the significance of these estimated market values which can fluctuate based on such factors as interest rates, inflation, monetary policy and general economic conditions.

	(iii) Fair values of equity securities with active markets are based on quoted market prices. For other equity securities, fair values are based on external market valuations.

	(iv) Fair values of real estate mortgages and notes receivable are estimated individually as the value of the discounted future cash flows of the loan, subject to the estimated fair value of the underlying collateral.

	(v) The fair value of the interest rate swap is based on a price quoted by a dealer.

	(vi) Long term debt consists of mortgages payable, long term notes and capital securities. Fair values of mortgages payable are estimated using discounted cash flow analyses. Fair values of the long term notes and capital securities are based on prices quoted by dealers.

	(vii) Fair values of credit derivatives, principally portfolio credit default swaps, are determined using internal valuation models that are similar to external valuation models. Such valuations require considerable judgment and are subject to significant uncertainty. The fair values of credit default swaps are subject to fluctuations arising from, among other factors, changes in credit spreads, the financial ratings of referenced asset-backed securities, actual credit events reducing subordination, credit correlation within a portfolio, anticipated recovery rates related to potential defaults and changes in interest rates.

(a) The authorized but unissued preferred shares may be issued in one or more series and the shares of each series shall have such rights as fixed by the Board of Directors.

(b) In June 2003, Chubb sold 15,525,000 shares of common stock through a public offering. The net proceeds from the sale of $887 million were credited to common stock and paid-in surplus.

(c) In June 2003, Chubb issued 18.4 million purchase contracts to purchase the Corporation’s common stock and $460 million of 2.25% senior notes. The purchase contracts and notes were issued together in the form of 7% equity units. In November 2002, Chubb issued 24 million mandatorily exercisable warrants to purchase the Corporation’s common stock and $600 million of 4% senior notes. The warrants and notes were issued together in the form of 7% equity units. For further discussion of the notes and equity units, see Note (10)(a).

Each purchase contract obligates the holder to purchase, and obligates Chubb to sell, on or before August 16, 2006, for a settlement price of $25, a variable number of newly issued shares of the Corporation’s common stock. Each warrant obligates the holder to purchase, and obligates Chubb to sell, on or before November 16, 2005, for a settlement price of $25, a variable number of newly issued shares of the Corporation’s common stock. The number of shares of the Corporation’s common stock to be purchased will be determined based on a formula that considers the market price of the Corporation’s common stock immediately prior to the time of settlement in relation to the sale price of the common stock at the time the respective equity units were offered, which was $59.50 per share for the June 2003 offering and $56.64 per share for the November 2002 offering. Upon settlement of the purchase contracts, Chubb will receive proceeds of approximately $460 million and will issue between approximately 6.5 million and 7.7 million shares of common stock. Upon settlement of the warrants, Chubb will receive proceeds of approximately $600 million and will issue between approximately 8.7 million and 10.6 million shares of common stock.

Chubb will make quarterly contract adjustment payments to the equity unit holders at a rate of 4.75% per year on the stated amount of $25 per purchase contract until the purchase contract is settled. Chubb will make quarterly warrant fee payments to the equity unit holders at a rate of 3% per year on the stated amount of $25 per warrant until the warrant is settled. The $66.2 million present value of the contract adjustment payments and the $49.9 million present value of the warrant fee payments were accrued as a liability at the date of issuance of the respective equity units with an offsetting charge to paid-in surplus. Subsequent contract adjustment and warrant fee payments will be allocated between this liability account and interest expense based on a constant rate calculation over the respective term of the purchase contracts and warrants. Paid-in surplus also reflected a charge of $11.9 million in 2003 and $15.0 million in 2002, representing the portion of the equity unit issuance costs that was allocated to the purchase contracts and warrants, respectively.

(d) The Corporation has a shareholders rights plan under which each shareholder has one right for each share of common stock of the Corporation held. Each right entitles the holder to purchase from Chubb one one-thousandth of a share of Series B Participating Cumulative Preferred Stock at an exercise price of $240. The rights are attached to all outstanding shares of common stock and trade with the common stock until the rights become exercisable. The rights are subject to adjustment to prevent dilution of the interests represented by each right.

The rights will become exercisable and will detach from the common stock ten days after a person or group either acquires 20% or more of the outstanding shares of the Corporation’s common stock or announces a tender or exchange offer which, if consummated, would result in that person or group owning 20% or more of the outstanding shares of the Corporation’s common stock.

In the event that any person or group acquires 20% or more of the outstanding shares of the Corporation’s common stock, each right will entitle the holder, other than such person or group, to purchase that number of shares of the Corporation’s common stock having a market value of two times the exercise price of the right. In the event that, following the acquisition of 20% or more of the Corporation’s outstanding common stock by a person or group, the Corporation is acquired in a merger or other business combination transaction or 50% or more of the Corporation’s assets or earning power is sold, each right will entitle the holder to purchase common stock of the acquiring company having a value equal to two times the exercise price of the right.

At any time after any person or group acquires 20% or more of the Corporation’s common stock, but before such person or group acquires 50% or more of such stock, the Corporation may exchange all or part of the rights, other than the rights owned by such person or group, for shares of the Corporation’s common stock at an exchange ratio of one share of common stock per right.

The rights do not have the right to vote or to receive dividends. The rights may be redeemed in whole, but not in part, at a price of $0.01 per right by the Corporation at any time until the tenth day after the acquisition of 20% or more of the Corporation’s outstanding common stock by a person or group. The rights will expire at the close of business on March 12, 2009, unless previously exchanged or redeemed by the Corporation.

(e) The property and casualty insurance subsidiaries are required to file annual statements with insurance regulatory authorities prepared on an accounting basis prescribed or permitted by such authorities (statutory basis). For such subsidiaries, statutory accounting practices differ in certain respects from GAAP.

A comparison of shareholders’ equity on a GAAP basis and policyholders’ surplus on a statutory basis is as follows:

(f) As a holding company, Chubb’s ability to continue to pay dividends to shareholders and to satisfy its obligations, including the payment of interest and principal on debt obligations, relies on the availability of liquid assets in Chubb, which is dependent in large part on the dividend paying ability of its property and casualty insurance subsidiaries. Various state insurance laws restrict the Corporation’s property and casualty insurance subsidiaries as to the amount of dividends they may pay without the prior approval of regulatory authorities. The restrictions are generally based on net income and on certain levels of policyholders’ surplus as determined in accordance with statutory accounting practices. Dividends in excess of such thresholds are considered “extraordinary” and require prior regulatory approval. During 2003, these subsidiaries paid cash dividends to Chubb totaling $270.0 million.

The maximum dividend distribution that may be made by the property and casualty insurance subsidiaries to Chubb during 2004 without prior approval is approximately $630 million.

Summarized unaudited quarterly financial data for 2003 and 2002 are shown below. In management’s opinion, the interim financial data contain all adjustments, consisting of normal recurring items, necessary to present fairly the results of operations for the interim periods.


(a)	In the third quarter of 2002, losses and expenses included net losses of $625.0 million ($406.3 million after-tax or $2.38 per basic and diluted share) related to asbestos and toxic waste claims. Excluding the impact of such losses, the losses to premiums earned ratio was 68.7% and the combined ratio was 99.9%.

(b)

In the fourth quarter of 2003, losses and expenses included net losses of $250.0 million ($162.5 million after-tax or $0.86 per basic and diluted share) related to asbestos claims. Excluding the impact of such losses, the losses to premiums earned ratio was 65.2% and the combined ratio was 94.8%. Losses and expenses also included a $96.0 million loss ($62.4 million after-tax or $0.33 per basic and diluted share) related to an agreement that caps Chubb Financial Solutions’ exposure from two credit derivative contracts that had experienced deterioration in credit quality. Federal and foreign income tax included a $40.0 million ($0.21 per basic and diluted share) credit for the reversal of the tax valuation allowance established in 2002.

(c)

In the fourth quarter of 2002, losses and expenses included net losses of $75.0 million ($48.7 million after-tax or $0.29 per basic and diluted share) related to asbestos claims and a reduction in net surety losses of $88.0 million ($57.2 million after-tax or $0.33 per basic and diluted share) resulting from the settlement of litigation related to Enron Corp. Excluding the effect of such losses, the losses to premiums earned ratio was 70.9% and the combined ratio was 101.8%. Federal and foreign income tax included a $40.0 million ($0.23 per basic and diluted share) charge to establish a tax valuation allowance from not being able to recognize, for accounting purposes, certain U.S. tax benefits related to European losses.

CONSOLIDATED SUMMARY OF INVESTMENTS — OTHER THAN INVESTMENTS IN RELATED PARTIES

The condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto.

Chubb and its domestic subsidiaries file a consolidated federal income tax return. The federal income tax (credit) represents an allocation under the Corporation’s tax allocation agreements.

The condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto.

In 2002, Chubb contributed $131.9 million of property, consisting of land and office buildings in Whitehouse Station, New Jersey, to a consolidated insurance subsidiary and another consolidated insurance subsidiary distributed its $259.1 million investment in a partially owned company, Allied World Assurance Holdings, Ltd., to Chubb. These noncash transactions have been excluded from the statement of cash flows.


*	Property and casualty assets are available for payment of losses and expenses for all classes of business; therefore, such assets and the related investment income have not been allocated to the underwriting segments.
