PART I.
ITEM 1. BUSINESS

GENERAL

The Chubb Corporation (the Corporation) was incorporated as a business
corporation under the laws of the State of New Jersey in June 1967. The
Corporation is a holding company with subsidiaries principally engaged in the
property and casualty insurance business. The Corporation and its subsidiaries
employed approximately 11,900 persons worldwide on December 31, 1999.

In July 1999, the Corporation completed its acquisition of Executive Risk
Inc. The results of operations of Executive Risk are included in the
Corporation's consolidated results of operations from the date of acquisition.
Executive Risk offers directors and officers, errors and omissions and
professional liability coverages through its insurance subsidiaries, Executive
Risk Indemnity Inc., Executive Risk Specialty Insurance Company and Quadrant
Indemnity Company. Additional information related to the Corporation's
acquisition of Executive Risk is included in Note (3) of the notes to
consolidated financial statements incorporated by reference from the
Corporation's 1999 Annual Report to Shareholders.

Revenues, income before income tax and assets for each operating segment
for the three years ended December 31, 1999 are included in Note (16) of the
notes to consolidated financial statements incorporated by reference from the
Corporation's 1999 Annual Report to Shareholders.

The property and casualty insurance subsidiaries provide insurance
coverages principally in the United States, Canada, Europe and parts of
Australia, Latin America and the Far East. Revenues of the property and casualty
insurance subsidiaries by geographic area for the three years ended December 31,
1999 are included in Note (16) of the notes to consolidated financial statements
incorporated by reference from the Corporation's 1999 Annual Report to
Shareholders.

PROPERTY AND CASUALTY INSURANCE

The principal members of the Property and Casualty Insurance Group (the
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 Specialty
Insurance Company and Quadrant Indemnity Company in the United States, as well
as Chubb Insurance Company of Canada, Chubb Insurance Company of Europe, S.A.,
Chubb Insurance Company of Australia Limited, Chubb do Brasil Companhia de
Seguros and Chubb Atlantic Indemnity Ltd.

Federal is the manager of Vigilant, Pacific Indemnity, Great Northern,
Chubb National, Chubb Indemnity and Chubb New Jersey. Effective January 1, 2000,
Federal became the manager of Executive Risk Indemnity Inc., Executive Risk
Specialty Insurance Company and Quadrant Indemnity Company. Federal also
provides certain services to other members of the Group. Acting subject to the
supervision and control of the Boards of Directors of the members of the Group,
the Chubb & Son division of 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.

The Group presently underwrites most forms of property and casualty
insurance. All members of the Group write non-participating policies. Several
members of the Group also write participating policies, particularly in the
workers' compensation class of business, under which dividends are paid to the
policyholders.

Premiums Written
An analysis of the Group's premiums written during the past three years is
shown in the following table:

(a) Intercompany items eliminated.

Reinsurance premiums assumed and ceded in 1997 were affected by changes in
reinsurance agreements with the Royal & Sun Alliance Insurance Group plc (Sun
Alliance). These changes are described in Note (8) of the notes to consolidated
financial statements incorporated by reference from the Corporation's 1999
Annual Report to Shareholders.

The net premiums written during the last five years for major classes of
the Group's business are incorporated by reference from page 16 of the
Corporation's 1999 Annual Report to Shareholders.

One or more members of the 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 and parts of Australia, Latin America and the
Far East. In 1999, approximately 82% of the Group's direct business was produced
in the United States, where the Group's businesses enjoy broad geographic
distribution with a particularly strong market presence in the Northeast. The
five states accounting for the largest amounts of direct premiums written were
New York with 13%, California with 10% and New Jersey, Pennsylvania and Texas
each with 5%. No other state accounted for 5% or more of such premiums.
Approximately 10% of the Group's direct premiums written was produced in Europe
and 4% was produced in Canada.

Underwriting Results

A frequently used industry measurement of property and casualty insurance
underwriting results is the combined loss and expense ratio. 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,
other non-underwriting income or expense and income taxes are not reflected in
the combined ratio. The profitability of property and casualty insurance
companies depends on income from both underwriting operations and investments.

The net premiums and the loss, expense and combined loss and expense ratios
of the Group for the last five years are shown in the following table:



NET PREMIUMS COMBINED

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, 1999 and 1998, such ratio for the Group was 1.76 and
1.95, respectively.

Producing and Servicing of Business

In the United States and Canada, the Group is represented by approximately
4,500 independent agents and accepts business on a regular basis from an
estimated 1,100 insurance brokers. In most instances, these agents and brokers
also represent other companies which compete with the Group. The offices
maintained by the Group assist these agents and brokers in producing and
servicing the Group's business. In addition to the administrative offices in
Warren, New Jersey, the Group operates 7 zone offices and branch and service
offices throughout the United States and Canada.

The Group's overseas business is developed by its foreign agents and
brokers through local branch offices of the Group and by its United States and
Canadian agents and brokers. In conducting its overseas business, the Group
reduces the risks relating to currency fluctuations by maintaining investments
in those foreign currencies in which the Group transacts business, with
characteristics similar to the liabilities in those currencies. The net asset or
liability exposure to the various foreign currencies is regularly reviewed.

Business for the Group is also produced through participation in a number
of underwriting pools and syndicates including, among others, Associated
Aviation Underwriters, Cargo Reinsurance Association, American Cargo War Risk
Reinsurance Exchange and American Accident Reinsurance Group. 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.

Reinsurance

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

A large portion of the Group's reinsurance is effected under contracts
known as treaties under which all risks meeting prescribed criteria are
automatically covered. Most of the 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 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 Group's capacity to
underwrite risks changes. Reinsurance contracts do not relieve the Group of its
primary obligation to the policyholders.

The existing reinsurance program of the Executive Risk insurance
subsidiaries at the time of the acquisition was designed to limit the loss
retained from a loss occurrence to an amount lower than that typically retained
by the Group. Executive Risk has utilized reinsurance to a greater extent
because its size has limited the amount of risk it could retain. Most of
Executive Risk's reinsurance program has been left in place and will be reviewed
during 2000.

The collectibility of reinsurance is subject to the solvency of the
reinsurers. The Group is selective in regard to its reinsurers, placing
reinsurance with only those reinsurers with strong balance sheets and superior
underwriting ability. The Group monitors the financial strength of its
reinsurers on an ongoing basis. As a result, uncollectible amounts have not been
significant.

The Group has an exposure to insured losses caused by hurricanes,
earthquakes, winter storms, windstorms and other catastrophic events. The
frequency and severity of catastrophes are unpredict-

4
5

able. 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. The Group continually assesses its concentration of underwriting
exposures in catastrophe prone areas globally and develops strategies to manage
this exposure through individual risk selection, subject to regulatory
constraints, and through the purchase of catastrophe reinsurance. The Group uses
modeling techniques and concentration management tools that allow it to better
monitor and control catastrophe exposures. The Group maintains records showing
concentrations of risk in catastrophe prone areas such as California (earthquake
and brush fires) and the Southeast coast of the United States (hurricanes). The
Group's current catastrophe reinsurance program provides coverage for individual
catastrophic events of approximately 78% of losses between $100 million and $450
million in the United States and approximately 90% of losses between $25 million
and $175 million outside the United States.

Unpaid Claims and Claim Adjustment Expenses and Related Amounts Recoverable
from Reinsurers

Insurance companies are required to establish a liability in their accounts
for the ultimate costs (including claim adjustment expenses) of claims which
have been reported but not settled and of claims which 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 claims and claim
adjustment expenses is a complex and imprecise science that reflects significant
judgmental factors. This is true because claim settlements to be made in the
future will be impacted by changing rates of inflation and other economic
conditions, changing legislative, judicial and social environments and changes
in the Group's claim handling procedures. In many liability cases, significant
periods of time, ranging up to several years or more, may elapse between the
occurrence of an insured loss, the reporting of the loss to the Group and the
settlement of the loss. Approximately 65% of the Group's net unpaid claims and
claim adjustment expenses at December 31, 1999 were for incurred but not
reported (IBNR) losses--claims which had not yet been reported to the Group,
some of which were not yet known to the insured, and future development on
reported claims. In spite of this imprecision, financial reporting requirements
dictate that insurance companies report a single amount as the estimate of
unpaid claims and claim adjustment expenses as of each evaluation date. These
estimates are continually reviewed and updated. Any resulting adjustments are
reflected in current operating results.

The Group's estimates of losses for reported claims are established
judgmentally on an individual case basis. Such estimates are based on the
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 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 Group's estimates are based on both
expected and actual reported losses. Salvage and subrogation estimates are
developed from patterns of actual recoveries.

The Group's estimates of unpaid claim adjustment expenses are based on
analyses of the relationship of projected ultimate claim 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 Group's estimates of reinsurance recoverable related to reported and
unreported claims and claim 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.

The anticipated effect of inflation is implicitly considered when
estimating liabilities for unpaid claims and claim adjustment expenses.
Estimates of the ultimate value of all unpaid claims 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 claims. There is no precise method for subsequently evaluating
the adequacy of the consideration given to inflation, since claim settlements
are affected by many factors.

The following table provides a reconciliation of the beginning and ending
liability for unpaid claims and claim adjustment expenses, net of reinsurance
recoverable, and a reconciliation of the ending net liability to the
corresponding liability on a gross basis for the years ended December 31, 1999,
1998 and 1997:

========= ========= ========


As reestimated at December 31, 1999, the liability for unpaid claims and
claim adjustment expenses, net of reinsurance recoverable, as established at the
previous year-end was redundant by $205.6 million. This compares with favorable
development of $218.4 million and $65.3 million during 1998 and 1997,
respectively. Such redundancies were reflected in the Group's operating results
in these respective years. Each of the past three years benefited from favorable
claim experience for certain liability classes; this was offset in part by
losses incurred relating to asbestos and toxic waste claims of $46.8 million,
$67.8 million and $125.2 million in 1999, 1998 and 1997, respectively. The
higher favorable development in 1999 and 1998 compared with 1997 was due to more
favorable loss experience for executive protection and excess liability
coverages as well as the substantially lower incurred losses related to asbestos
and toxic waste claims.

As a result of the termination of the reinsurance agreements with Sun
Alliance, there were portfolio transfers of gross loss reserves and reinsurance
recoverable as of January 1, 1997. The effect of these portfolio transfers was
to increase net loss reserves by $286.2 million in 1997 and decrease paid losses
by the same amount. The loss portfolio transfers had no effect on incurred
claims and claim adjustment expenses.

Unpaid claims and claim adjustment expenses, net of reinsurance
recoverable, increased by $698.9 million in 1999, $485.3 million in 1998 and
$808.7 million in 1997. The increase in 1999 includes $605.8 million of net
reserves assumed in July upon the acquisition of Executive Risk. The 1999
increase would have been $548.7 million greater except that loss reserves were
reduced by payments in that amount during the year related to the settlement of
asbestos-related claims against Fibreboard Corporation. The Fibreboard reserves
and related loss payments are presented in the table on page 7.

The Fibreboard settlement is further discussed in Item 7 of this report on pages
21 and 22. The increase in net loss reserves in 1997 includes the effect of the
portfolio transfers with Sun Alliance.

Excluding the Fibreboard reserves, the effect of the Executive Risk
reserves assumed and the effect of the portfolio transfers, loss reserves, net
of reinsurance recoverable, increased by $641.8 million or 8% in 1999, $485.3
million or 6% in 1998, and $516.5 million or 7% in 1997. Substantial reserve
growth has occurred each year in those liability classes, primarily excess
liability and executive protection, that are characterized by delayed loss
reporting and extended periods of settlement. These coverages represent a
significant portion of the Group's business. The 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
year-end 1999 was flat compared with the number at year-end 1998, which was in
turn 4% higher than that at year-end 1997.

The uncertainties relating to unpaid claims, particularly for asbestos and
toxic waste claims on insurance policies written many years ago, are discussed
in Item 7 of this report on pages 20 through 23.

The following table provides a reconciliation of the beginning and ending
liability for unpaid claims and claim adjustment expenses, net of reinsurance
recoverable, related to asbestos and toxic waste claims for the years ended
December 31, 1999, 1998 and 1997. Reinsurance recoveries related to such claims
are not significant.

- ---------------
(a) As a result of the termination of the reinsurance agreements with Sun
Alliance, there was a portfolio transfer of asbestos and toxic waste loss
reserves as of January 1, 1997. The effect of the portfolio transfer was to
increase loss reserves by $55.6 million and decrease paid losses by the same
amount. The loss portfolio transfer had no effect on incurred claims and
claim adjustment expenses.

The method by which asbestos claims are established by the Group's claim
staff was changed in 1998. Previously, claims were generally established for
each lawsuit. Since the change was implemented in 1998, one master claim is
generally established for all similar claims and lawsuits involving an insured.
Prior year claim counts were not adjusted to conform to the new methodology. A
counted claim can have from one to thousands of claimants. Management does not
believe the following claim count data is meaningful for analysis purposes.

There were approximately 1,600 asbestos claims outstanding at December 31,
1999 compared with 2,000 asbestos claims outstanding at December 31, 1998 and
3,700 asbestos claims outstanding at December 31, 1997. In 1999, approximately
200 claims were opened and 600 claims were closed. In 1998, approximately 500
claims were opened and 2,200 claims were closed, including claims "closed" to
adjust the data base to the methodology implemented in 1998. In 1997,
approximately 1,300 claims were opened and 1,500 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,
1999 compared with 650 toxic waste claims outstanding at December 31, 1998 and
800 toxic waste claims outstanding at December 31, 1997. Approximately 300
claims were opened in 1999, 250 claims were opened in 1998 and 300 claims were
opened in 1997. There were approximately 350 claims closed in 1999, 400 claims
closed in 1998 and 300 claims closed in 1997. Generally, a toxic waste claim is
established for each lawsuit, or alleged equivalent, against an insured where
potential liability has been determined to exist

7
8

under a policy issued by a member of the Group. Because indemnity payments to
date for toxic waste claims have not been significant in the aggregate and 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 claims and claim adjustment expenses, net of
reinsurance recoverable, for the ten years prior to 1999. The amounts in the
table for the years ended December 31, 1989 through 1998 do not include
Executive Risk's unpaid claims and claim adjustment expenses. The top line of
the table shows the estimated liability for unpaid claims and claim 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
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 the current year's operating
results. 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, 1999. The amounts noted are cumulative
in nature; that is, an increase in a loss estimate that related to a prior
period occurrence generates a deficiency in each intermediate year. For example,
a deficiency recognized in 1993 relating to losses incurred prior to December
31, 1989, such as the $675.0 million increase in loss reserves related to the
Fibreboard settlement, would be included in the cumulative deficiency amount for
each year in the period 1989 through 1992. Yet, the deficiency would be
reflected in operating results only in 1993. The effect of changes in estimates
of the liabilities for claims occurring in prior years on income before income
taxes in each of the past three years is shown in the reconciliation table on
page 6.

In each of the years 1989 through 1998, there was favorable development for
certain liability classes as the result of favorable loss experience. In each of
these years, this favorable development was offset, in varying degrees, by
unfavorable development related to asbestos and toxic waste claims. The years
1989 through 1992 in particular reflect the effects of the $675 million increase
in loss reserves related to the Fibreboard settlement. The cumulative net
deficiencies experienced relating to asbestos and toxic waste claims were also,
to varying degrees, the result of: (1) an increase in the actual number of
claims filed; (2) an increase in the number of unasserted claims estimated; (3)
an increase in the severity of actual and unasserted claims; and (4) an increase
in litigation costs associated with such claims.

Conditions and trends that have affected development of the liability for
unpaid claims and claim 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 1989 column, as of December 31, 1999 the Group had paid
$3,922.1 million of the currently estimated $4,798.9 million of claims and claim
adjustment expenses that were unpaid at the end of 1989; thus, an estimated
$876.8 million of losses incurred through 1989 remain unpaid as of December 31,
1999, approximately 60% 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 beginning
with 1992 and the reestimation of these amounts as of December 31, 1999. Amounts

The amounts for the years 1989 through 1998 do not include Executive Risk's
unpaid claims and claim adjustment expenses. During the period from the date
Executive Risk was acquired through December 31, 1999, the decrease in its
estimates for claims occurring in prior years was $10.5 million.

The cumulative deficiencies for the years 1989 through 1992 include the effect
of the $675 million increase in claims and claim adjustment expenses related to
the Fibreboard settlement.

Investments

Investment decisions are centrally managed by investment professionals
based on guidelines established by management and approved by the board of
directors for each member of the Group.

The main objectives in managing the investment portfolio of the Group 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. To accomplish this, the investment function must be
highly integrated with the operating functions and capable of responding to the
changing conditions in the marketplace. Investment strategies are developed
based on many factors including underwriting results and the Group's resulting
tax position, regulatory requirements, fluctuations in interest rates and
consideration of other market risks.

The investment portfolio of the Group is primarily comprised of high
quality bonds, principally tax-exempt, U.S. Treasury, government agency,
mortgage-backed securities and corporate issues. In addition, the portfolio
includes equity securities held primarily with the objective of capital
appreciation.

In 1999, the Group invested new cash primarily in tax-exempt bonds and
corporate bonds. In 1998, the Group invested new cash primarily in tax-exempt
bonds and, to a lesser extent, equity securities. In 1997, the Group invested
new cash primarily in tax-exempt bonds and, to a lesser extent, corporate bonds
and mortgage-backed securities. In each year, the Group tried to achieve the
appropriate mix in its portfolio to balance both investment and tax strategies.
At December 31, 1999, 70% of the Group's fixed maturity portfolio was invested
in tax-exempt bonds compared with 71% at December 31, 1998 and 68% at December
31, 1997.

The investment results of the Group for each of the past three years are

REAL ESTATE GROUP

The Real Estate Group is composed of Bellemead Development Corporation and
its subsidiaries. The Real Estate Group is involved in commercial development
activities primarily in New Jersey and residential development activities
primarily in central Florida.

In October 1996, the Corporation announced that the Real Estate Group was
exploring the possible sale of all or a portion of its real estate assets. In
November 1997, the Real Estate Group sold a substantial portion of its
commercial properties for $736.9 million,which included $628.3 million in cash
and the assumption of $108.6 million in debt. In addition to the sale to the
joint venture in November 1997, The Real Estate Group sold selected commercial
properties as well as residential properties in each of the past three years.

The Real Estate Group owns approximately $355 million of land, which is
expected to be developed in the future, and approximately $190 million of
commercial properties and land parcels under lease. The Real Estate Group is
continuing to explore the sale of certain of its remaining properties.
Additional information related to the Corporation's real estate operations is
included in Item 7 of this report on pages 24 and 25.

REGULATION, PREMIUM RATES AND COMPETITION

The Corporation 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 and its subsidiaries. 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 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 claims and claim 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 Group operates. Some
countries have minimal regulatory requirements, while others regulate insurers
extensively. Foreign insurers in many countries are faced with greater
restrictions than domestic competitors. In certain countries, the 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
11
12

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, 1999, each member of
the 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 Group underwrites. Ocean marine insurance
rates are exempt from regulation.

Subject to regulatory requirements, the Group's management determines the
prices charged for its policies based on a variety of factors including claim
and claim 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 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 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 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.

There are approximately 3,000 property and casualty insurance companies in
the United States operating independently or in groups and no single company or
group is dominant. According to A.M. Best, the Group is the 14th largest United
States property and casualty insurance group based on 1998 net premiums written.
The relatively large size and underwriting capacity of the Group provide
opportunities not available to smaller companies.

Price competition increased in the property and casualty marketplace during
1987 and has continued through 1999, particularly in the commercial classes. The
Group continues to be selective in the writing of new business and to reinforce
the sound relationships with customers who appreciate the stability, expertise
and added value the Group provides.

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 1999,
assessments to the members of the Group amounted to approximately $8.3 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

12
13

coverages. Some states also require insurers to participate in facilities that
provide homeowners and crime insurance. 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 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
limitation of Year 2000 liability, tort reform, natural disaster reinsurance,
hazardous waste removal and liability measures, containment of medical costs,
patients' rights, privacy, e-commerce, international trade, automobile safety,
financial services deregulation including the removal of barriers preventing
banks from engaging in the insurance business 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 product liability and
commercial general liability as well as extension and protection of employee
benefits, including workers' compensation and disability benefits.

Legislative and judicial developments pertaining to asbestos and toxic
waste exposures are discussed in Item 7 of this report on pages 20 through 23.

ITEM 2. PROPERTIES

The executive offices of the Corporation and the administrative offices of
the Property and Casualty Insurance Group are in Warren, New Jersey. The
Property and Casualty Insurance Group maintains zone administrative and branch
offices in major cities throughout the United States and also has offices in
Canada, Europe, Australia, the Far East and Latin America. Office facilities are
leased with the exception of buildings in Branchburg, New Jersey and Simsbury,
Connecticut. Management considers its office facilities suitable and adequate
for the current level of operations. See Note (14) of the notes to consolidated
financial statements incorporated by reference from the Corporation's 1999
Annual Report to Shareholders.

ITEM 3. LEGAL PROCEEDINGS

The Corporation and its subsidiaries are 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.

Information regarding certain litigation to which property and casualty
insurance subsidiaries of the Corporation are a party is included in Item 7 of
this report on pages 20 through 23.

PART II.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED SECURITY HOLDER
MATTERS

Incorporated by reference from the Corporation's 1999 Annual Report to
Shareholders, page 64.

ITEM 6. SELECTED FINANCIAL DATA

Selected financial data for the five years ended December 31, 1999 are
incorporated by reference from the Corporation's 1999 Annual Report to
Shareholders, pages 36 through 39.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

The following discussion presents our past results and our expectations for
the near term future. The supplementary financial information and the
consolidated financial statements and related notes, all of which are integral
parts of the following analysis of our results and our financial position, are
incorporated by reference from the Corporation's 1999 Annual Report to
Shareholders, pages 15, 16 and 40 through 61.

Certain statements in this document, as well as certain statements
incorporated by reference herein, may be considered to be "forward looking
statements" as that term is defined in the Private Securities Litigation Reform
Act of 1995, such as statements that include the words or phrases "will likely
result", "are expected to", "will continue", "is anticipated", "estimate",
"project" or similar expressions. Such statements are subject to certain risks
and uncertainties. The factors which could cause actual results to differ
materially from those suggested by any such statements include, but are not
limited to, those discussed or identified from time to time in the Corporation's
public filings with the Securities and Exchange Commission and specifically to:
risks or uncertainties associated with the Corporation's expectations with
respect to premium price increases, the non-renewal of underpriced insurance
accounts or business retention or profitability estimates, as well as with
respect to loss reserve adequacy, its investment income or cash flow
projections, or its announced real estate plans, and more generally, to: general
economic conditions including changes in interest rates and the performance of
the financial markets, changes in domestic and foreign laws, regulations and
taxes, changes in competition and pricing environments, regional or general
changes in asset valuations, the occurrence of significant natural disasters,
the development of major Year 2000 or privacy liabilities, the inability to
reinsure certain risks economically, the adequacy of loss reserves or currency
conversion transactions, as well as general market conditions, competition,
pricing and restructurings.

Operating income, which excludes realized investment gains and losses, was
$565 million in 1999 compared with $615 million in 1998 and $701 million in
1997. Operating income in 1998 reflects a first quarter restructuring charge of
$26 million after taxes related to the implementation of a cost control
initiative.

Net income, which includes realized investment gains and losses, was $621
million in 1999 compared with $707 million in 1998 and $770 million in 1997.

ACQUISITION OF EXECUTIVE RISK INC.

In July 1999, The Chubb Corporation (Corporation) completed its acquisition
of Executive Risk Inc. Executive Risk is a specialty insurance company offering
primarily executive protection coverages, particularly directors and officers,
errors and omissions and professional liability.

15
16

Executive Risk shareholders received 1.235 shares of the Corporation's
common stock for each outstanding common share of Executive Risk. In addition,
outstanding Executive Risk stock options were converted to stock options of the
Corporation. Approximately 14.3 million shares of common stock of the
Corporation were issued to Executive Risk shareholders and an additional 1.8
million shares of common stock of the Corporation were reserved for issuance
upon exercise of the converted Executive Risk stock options.

The acquisition has been accounted for using the purchase method of
accounting. Therefore, the results of operations of Executive Risk are included
in the Corporation's consolidated results of operations from the date of
acquisition. The assets and liabilities of Executive Risk were recorded at their
estimated fair values at the date of acquisition. The value of the stock options
assumed by the Corporation was included in the purchase price. The total
purchase price was approximately $832 million. The excess of the purchase price
over the estimated fair value of the net assets acquired, amounting to
approximately $517 million, has been recorded as goodwill and is being amortized
over 26 years.

PROPERTY AND CASUALTY INSURANCE

Property and casualty income before taxes was $626 million in 1999 compared
with $685 million in 1998 and $828 million in 1997. The decrease in earnings in
1999 was due to deterioration in underwriting results caused in large part by
the continued weakness in the standard commercial classes, which include
multiple peril, casualty and workers' compensation, and to a lesser extent,
higher catastrophe losses. The decrease in earnings in 1998 was due to a decline
in underwriting results
caused in large part by substantially higher catastrophe losses compared with
1997 and to a first quarter restructuring charge of $40 million before taxes.
Investment income increased in both 1999 and 1998 compared with the respective
prior years.

Catastrophe losses were $225 million in 1999, $173 million in 1998 and $57
million in 1997. The 1998 amount was net of reinsurance recoveries of
approximately $130 million related to Hurricane Georges. We did not have any
recoveries from our catastrophe reinsurance program during 1999 or 1997 since
there were no individual catastrophes for which our losses exceeded the initial
retention. Our initial retention level for each catastrophic event is
approximately $100 million in the United States and generally $25 million
outside the United States.

Reported net premiums written amounted to $5.7 billion in 1999, an increase
of 4% compared with 1998. Excluding premiums written by Executive Risk, premium
growth was 1% in 1999. Personal coverages accounted for $1.5 billion or 27% of
1999 premiums written, standard commercial coverages for $1.9 billion or 32% and
specialty commercial coverages for $2.3 billion or 41%. Reported net premiums
written increased 1% in 1998 compared with 1997. The reported growth in premiums
written in 1998 was affected by the termination in 1997 of certain reinsurance
agreements, which are discussed below.

For many years, a portion of the U.S. insurance business written by the
Corporation's property and casualty subsidiaries was reinsured on a quota share
basis with a subsidiary of the Sun Alliance Group plc. Similarly, a subsidiary
of the Corporation assumed a portion of Sun Alliance's property and casualty
business on a quota share basis. As a result of the 1996 merger of Sun Alliance
with Royal Insurance Holdings plc, the agreements pertaining to the exchange of
reinsurance were terminated effective January 1, 1997. Consequently, during
1997, the property and casualty subsidiaries retained a greater portion of the
business they wrote directly and assumed no reinsurance from Sun Alliance. There
was an additional impact on net premiums written in the first quarter of 1997
due to the effect of the portfolio transfers of unearned premiums as of January
1 of that year resulting from the changes in retention.

After adjusting 1997 reported net premiums for the effects of the
termination of the reinsurance agreements with Sun Alliance, net premiums
written increased 4% in 1998 compared with 1997.

Premium growth in personal lines was strong in both 1999 and 1998. In
commercial lines, intense competition in the worldwide marketplace has made
profitable premium growth difficult, particularly in the standard commercial
classes. Our priorities for 1999 were to renew good business at adequate prices
and not renew underperforming accounts where we could not attain price adequacy.
We made steady progress in this regard during 1999, increasing rates and
non-renewing underperforming business throughout the year. Further, many of our
competitors also increased rates during the latter part of 1999. As a result,
the pricing outlook in the standard commercial classes is considerably brighter
than it was at the outset of 1999.

Substantial premium growth was achieved in 1999 and 1998 outside the United
States, particularly in Europe, our largest foreign market. Excluding the
business that was assumed from Sun Alliance, non-U.S. premiums grew 12% and 9%
in 1999 and 1998, respectively, in original currency.

Underwriting results were unprofitable in 1999 compared with near-breakeven
results in 1998 and profitable results in 1997. The combined loss and expense
ratio, the common measure of underwriting profitability, was 102.8% in 1999
compared with 99.8% in 1998 and 96.9% in 1997.

The loss ratio was 70.3% in 1999 compared with 66.3% in 1998 and 64.5% in
1997. Losses from catastrophes represented 4.0 percentage points of the loss
ratio in 1999 compared with 3.3 percentage points in 1998 and 1.1 percentage
points in 1997. Catastrophe losses affecting results in 1999 resulted primarily
from weather-related events in the United States: winter storms in the first
quarter, windstorms and tornadoes in the second quarter and Hurricane Floyd in
the third quarter. The 1998 catastrophe losses resulted primarily from the
winter ice storms in Canada in the first quarter, the wind and hail storms in
the United States in the second quarter and Hurricane Georges in Puerto Rico in
the third quarter.

Our expense ratio was 32.5% in 1999 compared with 33.5% in 1998 and 32.4%
in 1997. The lower ratio in 1999 was due to salary and overhead expenses
decreasing due to a cost control initiative discussed below and a change in
accounting that resulted in the capitalization of certain costs incurred to
develop computer software for internal use. The increase in the expense ratio in
1998 was due primarily to an increase in commission expense caused in part by
higher contingent payments and also to written premiums growing at a somewhat
lesser rate than overhead expenses.

During the fourth quarter of 1997, we commenced an activity value analysis
process to identify and eliminate low-value activities and improve operational
efficiency while redirecting resources to activities having the greatest
potential to contribute to the Corporation's results. Implementation began in
the first quarter of 1998 and was substantially completed by the end of that
year. The cost control initiative resulted in approximately 500 job reductions
in the home office and the branch network through a combination of early
retirements, terminations and attrition. Other savings resulted from improved
vendor management and lower consulting expenses and other operating costs.

In the first quarter of 1998, we recorded a restructuring charge of $40
million related to the implementation of the cost control initiative. Of the $40
million restructuring charge, $30 million was comprised of accruals for
providing enhanced pension benefits and postretirement medical benefits to
employees who accepted an early retirement incentive offer and $5 million was
severance costs for employees who were terminated. The remainder of the charge
was for other expenses such as the cost of outplacement services. The initiative
was completed with no significant differences from the original estimates of the
restructuring costs. The liabilities related to the enhanced pension and
postretirement medical benefits were included in the pension and postretirement
medical benefits liabilities, which will be reduced as benefit payments are made
over time. Of the other restructuring costs, $1.5 million remained unpaid at
December 31, 1999.

PERSONAL INSURANCE

Our personal insurance business continued to produce exceptionally strong
results in 1999, measured by both growth and profitability.

Reported net premiums from personal insurance increased 12% in 1999
compared with a 5% increase in 1998. After adjusting 1997 reported net premiums
for the effects of the termination of the reinsurance agreement with Sun
Alliance, premium growth in 1998 was 10% compared with 1997. Our in-force policy
count increased in 1999 by about 10% for automobile, homeowners and other
personal coverages. Such growth was achieved while maintaining our disciplined
approach to pricing and risk selection. Premiums outside the United States grew
significantly in 1999 and 1998, although from a small base.

Our personal insurance business produced substantial underwriting profits
in each of the past three years. The combined loss and expense ratio was 89.9%
in 1999 compared with 85.6% in 1998 and 83.1% in 1997.

The profitability of our homeowners business each year is affected
substantially by the amount of catastrophe losses we incur. Homeowners results
were profitable by a similar margin in 1998 and 1997 as an unusually low
frequency of non-catastrophe related losses in 1998 substantially offset an
increase in catastrophe losses. Homeowners results in 1999 were less profitable
than in 1998 due to an increase in both catastrophe losses and non-catastrophe
losses. The frequency of non-catastrophe related losses returned to a more
normal level in 1999. Results in 1999 were also adversely affected by two large
losses aggregating $15 million net of reinsurance. Homeowners results were
unprofitable outside the United States in each of the past three years as we are
still building the critical mass necessary to absorb the costs of operating the
franchise. Catastrophe losses represented 11.8 percentage points of the loss
ratio for this class in 1999 compared with 8.5 percentage points in 1998 and 2.9
percentage points in 1997.

Our personal automobile business produced substantial profits in each of
the last three years. Results in each year benefited from stable loss frequency
and severity.

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

STANDARD COMMERCIAL INSURANCE

Reported net premiums from standard commercial insurance decreased 8% in
1999 compared with a 1% decrease in 1998. After adjusting 1997 reported net
premiums for the effects of the termination of the reinsurance agreement with
Sun Alliance, premiums increased 2% in 1998 compared with 1997. The decrease in
premiums in 1999 was the result of the strategy we put in place in late 1998 to
renew good business at adequate prices and not renew underperforming business
where we cannot attain price adequacy. As a result, retention levels were lower
in 1999 than in 1998. On the business that was renewed, rates have increased
steadily throughout 1999 and we expect this trend to continue. We achieved
premium growth in 1999 and 1998 in standard commercial lines outside the United
States.

Our standard commercial insurance business produced substantial
underwriting losses in each of the past three years, with results becoming
increasingly unprofitable each year. The combined loss and expense ratio was
123.6% in 1999 compared with 118.0% in 1998 and 114.5% in 1997.

It will take at least two annual renewal cycles to adequately reprice the
entire standard commercial book, and during that time we will continue to have
losses from underpriced business. Thus, it will be the latter part of 2000
before our pricing initiative is expected to have a noticeable effect on our
standard commercial results.

Multiple peril results were unprofitable in each of the past three years
due, in large part, to inadequate prices. Such results were progressively more
unprofitable each year. In the liability component of this class, results
deteriorated in 1998 and again in 1999 due to increases in the severity of
losses. Results in 1997 were adversely affected by substantial incurred losses
relating to asbestos and toxic waste claims. Results for the property component
deteriorated in 1998 due to higher catastrophe

18
19

losses compared with 1997. Property results deteriorated further in 1999 due
primarily to several large losses overseas. Catastrophe losses in 1999 were
similar to those in 1998. Catastrophe losses represented 9.6 percentage points
of the loss ratio for this class in 1999 compared with 8.6 percentage points in
1998 and 1.5 percentage points in 1997.

Results for our casualty business were unprofitable in each of the past
three years. Results deteriorated in 1999, primarily in the automobile and
primary liability components. In each year, but more so in 1998 and 1997,
casualty results were adversely affected by incurred losses relating to asbestos
and toxic waste claims. The excess liability component of our casualty coverages
was modestly unprofitable in 1999 compared with the near breakeven results in
1998 and the profitable results in 1997 due to increases in the frequency of
large losses as well as declining prices. Excess liability results in each of
the past three years benefited from favorable development of prior year loss
reserves. Results for the primary liability component were unprofitable in each
of the past three years, but more so in 1999 and 1997 due to a higher frequency
of large losses in those years. Results in the automobile component were
increasingly unprofitable in each of the past three years due to an increase in
the frequency of losses. Our commercial automobile book of business has been
inadequately priced, a consequence of the prolonged soft market.

Workers' compensation results were unprofitable in each of the past three
years, reflecting the cumulative effect of price reductions over the past
several years. Results were also adversely affected in 1999 and 1998 by an
increased frequency of large losses.

SPECIALTY COMMERCIAL INSURANCE

Reported net premiums from specialty commercial insurance increased by 9%
in 1999 compared with a 1% increase in 1998. Excluding premiums written by
Executive Risk, premium growth was 4% in 1999. After adjusting 1997 reported net
premiums for the effects of the termination of the reinsurance agreement with
Sun Alliance, premium growth in 1998 was 3% compared with 1997.

Our strategy of working closely with our customers and our ability to
differentiate our products continue to enable us to renew a large percentage of
our executive protection and financial institutions business. However, a
competitive market continues to put prices under pressure for this business.
Excluding premiums written by Executive Risk, executive protection premiums
increased 2% in 1999 while financial institutions premiums decreased 5%.

Property and marine premiums decreased due to the effect on retention
levels of pricing initiatives and non-renewing certain unprofitable accounts.
Other specialty commercial business includes $73 million of premiums in 1999
generated by Chubb Re, our reinsurance business that began operations during the
year.

Our specialty commercial business produced substantial underwriting profits
in each of the last three years. The combined loss and expense ratio was 93.6%
in 1999 compared with 91.5% in 1998 and 87.5% in 1997.

Property and marine results were unprofitable in each of the past three
years. The positive effect of the pricing initiatives and the culling of
unprofitable accounts in 1999 was somewhat offset by higher catastrophe losses.
Catastrophe losses for this class represented 10.2 percentage points of the loss
ratio in 1999 compared with 5.7 percentage points in 1998 and 4.9 percentage
points in 1997. Results in all three years were adversely affected by a high
frequency of large property losses, including several overseas losses in 1998
and 1997.

Executive protection results were highly profitable in each of the past
three years due to favorable loss experience on business worldwide, particularly
in the directors and officers and fiduciary components. However, such results
were less profitable in 1999 due to the less adequate prices in recent years.

Our financial institutions business was also profitable in each of the last
three years due to favorable loss experience in the fidelity component of this
business. The standard commercial business

19
20

written on financial institutions was unprofitable in 1999 and 1997 compared
with profitable results in 1998.

Our other commercial classes produced profitable results in 1999 and 1997
compared with near-breakeven results in 1998. The deterioration in 1998 was
attributable to our aviation business, which produced highly unprofitable
results. Our surety business produced highly profitable results in each of the
past three years.

REINSURANCE ASSUMED

Reinsurance assumed is treaty reinsurance that was assumed from Sun
Alliance. The reinsurance agreement with Sun Alliance was terminated effective
January 1, 1997. However, due to the lag in our reporting of such business, our
share of the Sun Alliance business for the last six months of 1996 was included
in our results in the first quarter of 1997. Such results were near breakeven.

LOSS RESERVES

Loss reserves are our property and casualty subsidiaries' largest
liability. At the end of 1999, gross loss reserves totaled $11.4 billion
compared with $10.4 billion and $9.8 billion at year-end 1998 and 1997,
respectively. Reinsurance recoverable on such loss reserves was $1.7 billion at
year-end 1999 compared with $1.3 billion and $1.2 billion at the end of 1998 and
1997, respectively. At year end 1999, gross loss reserves of $1.0 billion and
reinsurance recoverable of $390 million were related to Executive Risk.
Executive Risk has historically utilized reinsurance to a greater extent because
its size has limited the amount of risk it could retain.

Loss reserves, net of reinsurance recoverable, increased by $699 million or
8% in 1999 compared with $485 million or 6% in 1998. The increase in 1999
includes $606 million of net reserves assumed in July upon the acquisition of
Executive Risk. The 1999 increase would have been $549 million greater except
that loss reserves were reduced by payments in that amount during the year
related to the settlement of asbestos-related claims against Fibreboard
Corporation, which is discussed below. Excluding the Executive Risk reserves
assumed and the Fibreboard payments, loss reserves increased 7% in 1999.
Substantial reserve growth has occurred each year in those liability classes,
primarily excess liability and executive protection, that are characterized by
delayed loss reporting and extended periods of settlement.

During 1999, we experienced overall favorable development of $206 million
on loss reserves established as of the previous year-end. This compares with
favorable development of $218 million in 1998 and $65 million in 1997. Such
redundancies were reflected in operating results in these respective years. Each
of the past three years benefited from favorable claim experience for certain
liability classes; this was offset in part by losses incurred relating to
asbestos and toxic waste claims of $47 million, $68 million and $125 million in
1999, 1998 and 1997, respectively. The higher favorable development in 1999 and
1998 compared with 1997 was due to more favorable loss experience for executive
protection and excess liability coverages as well as the substantially lower
incurred losses related to asbestos and toxic waste claims.

The process of establishing loss reserves is a complex and imprecise
science that reflects significant judgmental factors. This is true because claim
settlements to be made in the future will be impacted by changing rates of
inflation and other economic conditions, changing legislative, judicial and
social environments and changes in our claim handling procedures. In many
liability cases, significant periods of time, ranging up to several years or
more, may elapse between the occurrence of an insured loss, the reporting of the
loss and the settlement of the loss. In fact, approximately 65% of our net loss
reserves at December 31, 1999 were 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.

Judicial decisions and legislative actions continue to broaden liability
and policy definitions and to increase the severity of claim payments. As a
result of this and other societal and economic

20
21

developments, the uncertainties inherent in estimating ultimate claim costs on
the basis of past experience continue to further complicate the already complex
loss reserving process.

The uncertainties relating to asbestos and toxic waste claims on insurance
policies written many years ago are exacerbated by inconsistent court decisions
and judicial and legislative interpretations of coverage that in some cases have
tended to erode the clear and express intent of such policies and in others have
expanded theories of liability. The industry 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.

Our most costly asbestos exposure related to an insurance policy issued to
Fibreboard Corporation by Pacific Indemnity Company in 1956. As a result of
events during 1999 that are described below, management believes that Pacific
Indemnity's exposure with respect to asbestos-related claims against Fibreboard
has ended.

In 1993, Pacific Indemnity Company, a subsidiary of the Corporation,
entered into a global settlement agreement with Continental Casualty Company (a
subsidiary of CNA Financial Corporation), Fibreboard Corporation, and attorneys
representing claimants against Fibreboard for all future asbestos-related bodily
injury claims against Fibreboard. This agreement was subject to final appellate
court approval. Pursuant to the global settlement agreement, a $1.525 billion
trust fund would be established to pay "future" claims, defined as claims that
were not filed in court before August 27, 1993. Pacific Indemnity would
contribute approximately $538 million to the trust fund and Continental Casualty
would contribute the remaining amount. In December 1993, upon execution of the
global settlement agreement, Pacific Indemnity and Continental Casualty paid
their respective shares into an escrow account. Upon final court approval of the
settlement, the amount in the escrow account, including interest earned thereon,
would be transferred to the trust fund.

Pacific Indemnity and Continental Casualty reached a separate agreement in
1993 for the handling of all "pending" asbestos-related bodily injury claims,
defined as claims pending on August 26, 1993 against Fibreboard. Pacific
Indemnity's obligation under this agreement with respect to such pending claims
was approximately $635 million, all of which was paid by the end of 1996. The
agreement further provided that the total responsibility of both insurers with
respect to pending and future asbestos-related bodily injury claims against
Fibreboard would be shared between Pacific Indemnity and Continental Casualty on
an approximate 35% and 65% basis, respectively.

At the same time, Pacific Indemnity, Continental Casualty and Fibreboard
entered into a trilateral agreement to settle all pending and future
asbestos-related bodily injury claims resulting from insurance policies that
were, or may have been, issued to Fibreboard by the two insurers. The trilateral
agreement would be triggered if the global settlement agreement was ultimately
disapproved. Pacific Indemnity's obligation under the trilateral agreement is
therefore similar to, and not duplicative of, that under those agreements
described above.

The trilateral agreement reaffirmed portions of an agreement reached in
March 1992 between Pacific Indemnity and Fibreboard. Among other matters, that
1992 agreement eliminated any Pacific Indemnity liability to Fibreboard for
asbestos-related property damage claims.

In July 1995, the United States District Court of the Eastern District of
Texas approved the global settlement agreement and the trilateral agreement. The
judgments approving these agreements were appealed to the United States Court of
Appeals for the Fifth Circuit. In July 1996, the Fifth Circuit Court affirmed
the 1995 judgments of the District Court. The objectors to the global settlement
agreement appealed to the United States Supreme Court. In June 1999, the Supreme
Court refused to affirm approval of the global settlement agreement. The case
was returned to the United States District Court of the Eastern District of
Texas for further proceedings. In September 1999, the District Court entered
judgment disapproving the global settlement agreement. That judgment was not
appealed and became final in November 1999.

The trilateral agreement was never appealed to the United States Supreme
Court and is final. Upon final disapproval of the global settlement agreement,
the trilateral agreement became effective.

21
22

In December 1999, the funds that had been held in the escrow account were paid
to a trust established to pay future asbestos-related bodily injury claims
against Fibreboard.

We continue to have potentially significant asbestos exposure, primarily on
those traditional defendants who manufactured, distributed or installed asbestos
products for whom we wrote excess liability coverages. Such exposure has
increased in recent years due to the erosion of much of the underlying limits
and the non-viability of other defendants.

Our other potential asbestos exposures are mostly peripheral defendants,
including a mix of manufacturers and distributors of certain products that
contain asbestos as well as premises owners. Generally, these insureds are named
defendants on a regional rather than a nationwide basis. As the resources of
traditional asbestos defendants have been depleted, more peripheral parties have
been drawn into litigation. Thus, we continue to receive notices of new asbestos
claims and new exposures on existing claims despite the fact that practically
all manufacturing and usage of asbestos ended nearly two decades ago.

Uncertainty remains as to our ultimate liability relating to asbestos
claims 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. Significant issues remain
unresolved, adding to the complexity and uncertainty of asbestos litigation.
These issues primarily involve questions regarding allocation of indemnity and
expense costs and exhaustion of policy limits. We are involved in disputes with
other insurers and with insureds over these issues, which increase the
difficulty of settlement negotiations.

Hazardous waste sites are another significant potential exposure. Under the
federal "Superfund" law and similar state statutes, when potentially responsible
parties (PRPs) fail to handle the clean-up, regulators have the work done and
then attempt to establish legal liability against the PRPs. The PRPs, with
proper government authorization in many instances, disposed of toxic materials
at a waste dump site or transported the materials to the site. Most sites have
multiple PRPs. 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 have become substantial, PRPs and
others have increasingly filed claims with their insurance carriers. Litigation
against insurers extends to issues of liability, coverage and other policy
provisions.

There is great 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. 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. Notwithstanding continued
pressure by the insurance industry and other interested parties to achieve a
legislative solution that would reform the liability provisions of the law,
Congress has not yet addressed the issue. It is currently 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.

The Superfund law does not address non-Superfund sites. For that reason, it
does not cover all existing hazardous waste exposures, such as those involving
sites that are subject to state law only. There remains significant uncertainty
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.

Litigation costs remain substantial, particularly for hazardous waste
claims. A substantial portion of the funds we have expended to date has been for
legal fees incurred in the prolonged litigation of coverage issues. Primary
policies provide a limit on indemnity payments but many do not limit defense

22
23

costs. This unlimited defense provided in the policies sometimes leads to the
payment of defense costs substantially exceeding the indemnity exposure.

Reserves for asbestos and toxic waste claims cannot be estimated with
traditional loss reserving techniques that rely on historical accident year loss
development factors. We have established 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 have been established to cover additional exposures on both known and
unasserted claims. These reserves are continually reviewed and updated. We have
evaluated ultimate incurred losses using newly emerging techniques for
estimating environmental liabilities and have expanded our claim data base. As a
result, we are somewhat more confident about the range of likely ultimate
incurred losses relating to asbestos and toxic waste claims. Therefore, the
incurred losses relating to asbestos and toxic waste claims were only $47
million in 1999 and $68 million in 1998, substantially less than the $125
million in 1997. Further increases in such loss reserves in 2000 and future
years are possible as legal and factual issues concerning these claims continue
to be clarified. The amount cannot be reasonably estimated.

Management believes that the aggregate loss reserves of the property and
casualty subsidiaries at December 31, 1999 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, management considers facts currently
known and the present state of the law and coverage litigation. However, given
the expansion of coverage and liability by the courts and the legislatures in
the past and the possibilities of similar interpretations in the future,
particularly as they relate to asbestos and toxic waste claims, as well as the
uncertainty in determining what scientific standards will be deemed acceptable
for measuring hazardous waste site clean-up, additional increases in loss
reserves may emerge which would adversely affect results in future periods. The
amount cannot reasonably be estimated at the present time.

CATASTROPHE EXPOSURE

The Corporation's property and casualty subsidiaries have an exposure to
insured losses caused by hurricanes, earthquakes, winter storms, windstorms and
other catastrophic events. The frequency and severity of 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 used modeling technologies and concentration management tools
that allow us to better monitor and control catastrophe exposures. 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.

INVESTMENTS AND LIQUIDITY

Growth in investment income in 1999 and 1998 was primarily due to increases
in invested assets, which reflected strong cash flow from operations over the
period, partially offset by lower average yields on new investments. The
effective tax rate on our investment income was 15.7% in 1999 compared with
15.3% in 1998 and 16.7% in 1997. The effective tax rate fluctuates each year as
a result of changes in the percentage of our portfolio invested in tax-exempt
bonds. Investment income after taxes increased 9% in 1999 compared with 1998 and
7% in 1998 compared with 1997. Excluding the investment income of Executive
Risk, such growth was 5% in 1999.

Generally, premiums are received by our property and casualty subsidiaries
months or even years before losses are paid under the policies purchased by such
premiums. These funds are used first to make current claim and expense payments.
The balance is invested together with the investment income generated by the
existing portfolio to build the portfolio and thereby increase future investment
income. Historically, cash receipts from operations, consisting of insurance
premiums and

23
24

investment income, have provided more than sufficient funds to pay losses,
operating expenses and dividends to the Corporation.

New cash available for investment by the property and casualty subsidiaries
was approximately $940 million in 1999 compared with $860 million in 1998 and
$1,260 million in 1997. New cash available in 1999 was not affected by the
Fibreboard-related payments during the year since such payments were made from
the escrow account that was funded in 1993. New cash in 1997 included
approximately $330 million received as the net result of the portfolio transfers
of unearned premiums and loss reserves as of January 1, 1997 related to the
termination of the reinsurance agreements with Sun Alliance.

In 1999, new cash was invested in tax-exempt bonds and corporate bonds.
Also, during 1999, we reduced our equity securities portfolio by approximately
$350 million with $145 million of the proceeds used to fund the purchase of a
28% interest in Hiscox plc, a leading U.K. personal and commercial specialty
insurer. In 1998, new cash was invested primarily in tax-exempt bonds and, to a
lesser extent, equity securities. In 1997, new cash was invested in tax-exempt
bonds and, to a lesser extent, corporate bonds and mortgage-backed securities.
In addition, in the first quarter of 1997, $250 million of foreign denominated
bonds were sold due to the reduction in foreign liabilities resulting from the
termination of the reinsurance agreements with Sun Alliance, with the proceeds
invested in U.S. dollar denominated securities. In each year, we tried to
achieve the appropriate mix in our portfolio to balance both investment and tax
strategies.

The property and casualty subsidiaries maintain sufficient investments in
highly liquid, short-term securities at all times to provide for immediate cash
needs, and the Corporation maintains bank credit facilities that are available
to respond to unexpected cash demands.

CORPORATE AND OTHER

Corporate and other includes investment income earned on corporate invested
assets, interest and other expenses not allocable to the operating subsidiaries,
and the results of our real estate subsidiary. Corporate and other produced a
loss before taxes of $4 million in 1999 compared with income of $23 million in
1998 and $41 million in 1997. The decrease in corporate and other income in 1998
and again in 1999 was due primarily to increasingly higher interest expense in
each year.

REAL ESTATE

In October 1996, we announced that we were exploring the possible sale of
all or a significant portion of our real estate assets. In November 1997, our
real estate subsidiary sold a substantial portion of its commercial properties
for $737 million, which included $628 million in cash and the assumption of $109
million in debt. The proceeds from the sale were used to repay outstanding short
term debt and certain term loans and mortgages. In the fourth quarter of 1996,
we had recorded an impairment loss of $255 million, or $160 million after taxes,
to reduce the carrying value of these assets to their estimated fair value.

Real estate operations resulted in a loss before taxes of $4 million in
both 1999 and 1998 and $9 million in 1997, which amounts are included in the
corporate and other results for those respective years.

Revenues in 1997 included $380 million from the November sale of real
estate properties. Proceeds received from that sale that related to mortgages
receivable are not classified as revenues. In addition to the November 1997
sale, we sold selected commercial properties as well as residential properties
in each of the past three years. Real estate revenues were $97 million in 1999,
$82 million in 1998 and $616 million in 1997. Revenues in 1999 and 1998 reflect
the reduced operating activity as a result of the sale of a substantial portion
of our real estate assets in 1997.

We own approximately $355 million of land which we expect will be developed
in the future. In addition, we own approximately $190 million of commercial
properties and land parcels under lease. We are continuing to explore the sale
of certain of our remaining properties.

24
25

Loans receivable, which were issued in connection with our joint venture
activities and other property sales, are primarily purchase money mortgages.
Such loans, which amounted to $81 million at December 31, 1999, are generally
collateralized by buildings and, in some cases, land. We continually evaluate
the ultimate collectibility of such loans and establish appropriate reserves.

The carrying value of the real estate assets we plan to dispose of in the
near term is based on the estimated fair value of these assets. The
recoverability of the carrying value of the remaining real estate assets is
assessed based on our ability to fully recover costs through a future revenue
stream. The assumptions used reflect a continued 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 as presently contemplated, it is possible that additional
impairment losses may be recognized.

INVESTMENT GAINS AND LOSSES

Net investment gains realized by the Corporation and its property and
casualty subsidiaries were as follows:



1999 1998 1997
---- ---- ----
(in millions)

Equity securities........................................... $63 $100 $ 75
Fixed maturities............................................ 24 42 30
--- ---- ----
Realized investment gains before tax........................ $87 $142 $105
=== ==== ====
Realized investment gains after tax......................... $56 $ 92 $ 68
=== ==== ====


Decisions to sell securities are governed principally by considerations of
investment opportunities and tax consequences. Thus, realized investment gains
and losses may vary significantly from year to year.

Sales of equity securities in each of the last three years resulted in net
realized investment gains due primarily to the significant appreciation in the
United States equity markets. 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.

Fixed maturity securities which the Corporation and its insurance
subsidiaries 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, 1999, 12% of
the fixed maturity portfolio was classified as held-to-maturity compared with
15% at December 31, 1998 and 18% at December 31, 1997.

The unrealized appreciation or depreciation of investments carried at
market value, which includes equity securities and fixed maturities classified
as available-for-sale, 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 $59 million, $138 million and $147 million at
December 31, 1999, 1998 and 1997, respectively. Such unrealized appreciation was
not reflected in the consolidated financial statements.

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

MARKET RISK

The main objectives in managing the investment portfolios of the
Corporation and its property and casualty subsidiaries 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.

Market risk represents the potential for loss due to adverse changes in the
fair value of financial instruments. The market risks of the Corporation and its
property and casualty subsidiaries relate primarily to the investment portfolio,
which exposes the Corporation to risks related to interest rates and, to a
lesser extent, credit quality, prepayment, foreign currency exchange rates and
equity prices. 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 fixed income security to
changes in interest rates. 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 and its
property and casualty subsidiaries.

The table on the following page 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, 1999 and 1998. The
cash flows are based on the earlier of the call date or the maturity date or,
for mortgage-backed securities, expected payment patterns. Actual cash flows
could differ from the expected amounts.

The Corporation and its property and casualty subsidiaries have
consistently invested in high quality marketable securities. As a result, we
believe that we have minimal credit quality risk. Taxable bonds in our domestic
portfolio comprise U.S. Treasury, government agency, mortgage-backed and
corporate securities. During 1998, to increase our investment returns, we
shifted a portion of the taxable portfolio from government agency
mortgage-backed securities and lower yielding U.S. Treasury securities to
commercial mortgage-backed securities and corporate bonds. Approximately 60% of
taxable bonds 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,
approximately 90% are rated AA or better with more than half rated AAA. Only 1%
of our bond portfolio is below investment grade. Taxable bonds have an average
maturity of 7 years while tax-exempt bonds mature on average in 9 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 and
the effective yield of a security. Such risk exists primarily within our

27
28

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 33% and 40% of our taxable bond
portfolio at year-end 1999 and 1998, respectively. About 35% of our
mortgage-backed securities holdings at December 31, 1999 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 40% of our
mortgage-backed securities were call protected AAA rated commercial securities.
The remaining mortgage-backed holdings were all 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 their 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 we have loss reserves and other liabilities. Such
investments have characteristics similar to our liabilities in those currencies.
At December 31, 1999, the property and casualty subsidiaries held foreign
investments of $1.5 billion supporting their international operations. Such
foreign 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 Canadian dollar and the
British pound sterling. The table below provides information about those fixed
maturity investments that are denominated in these two currencies. The table
presents cash flows of principal amounts in U.S. dollar equivalents by expected
maturity dates at December 31, 1999 and 1998. Actual cash flows could differ
from the expected amounts.

Equity price risk is the potential loss arising from adverse changes in the
value of equity securities. 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 equity securities are high
quality, diversified across industries and readily marketable. A hypothetical
decrease of 10% in the

28
29

market prices of the equity securities held at December 31, 1999 and 1998 would
have resulted in a decrease of $77 million and $109 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.

Interest rate risk also exists on our debt obligations. At December 31,
1999, the expected cash flows of principal amounts of such debt obligations were
a $15 million 7.3% term loan in 2001, $100 million of 6 7/8% notes in 2003 and
$642 million after 2004 with a weighted average interest rate of 7.0%.

YEAR 2000 READINESS DISCLOSURE

The Year 2000 issue referred to the potential that certain information
technology (IT) systems and applications as well as non-IT systems, such as
equipment with embedded chips and microprocessors, would be unable to properly
process data containing dates beginning with the year 2000. The issue existed
because many computer systems used two digits rather than four to define the
applicable year. Such systems, if not remediated, might have recognized the date
"00" as the year 1900 rather than the year 2000, resulting in a system failure
or miscalculation causing disruptions of normal business activities or other
unforeseen problems.

In 1995, we initiated a project to ensure Year 2000 readiness of the
Corporation's systems and applications. A significant focus of the project was
the retirement, renovation or rewriting of those mainframe systems that were not
Year 2000 ready. From 1995 through 1999, we completed remediation and testing
procedures on all of our mainframe IT systems as well as our personal computers,
servers and other non-mainframe computers and related software. Our Year 2000
compliance project also included developing a plan to evaluate the readiness of
third parties with whom we interact, preparing contingency plans to address the
noncompliance of any such third parties and physically testing electronic data
interchanges with third parties for Year 2000 compliance.

As a result of these remediation efforts, our internal systems proved to be
Year 2000 ready and we did not have any significant Year 2000 related
difficulties interacting with any third party with whom we conduct business. We
have not experienced any disruption of our business and therefore we have not
needed to implement any contingency plans.

The Year 2000 team included employees of the Corporation and software
consultants. A portion of the remediation effort was accomplished by redirecting
existing systems resources to the Year 2000 effort. However, we do not believe
that this had a significant adverse effect on other systems initiatives.

The cost to address the Year 2000 IT systems issue, including compensation
of employees and the cost of consultants, approximated $36 million.
Approximately $6 million, $14 million and $9 million was incurred in 1999, 1998
and 1997, respectively. These amounts do not include the cost of computer
equipment purchased to replace equipment that would have been upgraded in the
normal course of business, but not necessarily prior to January 2000. Future
expenditures related to the Year 2000 issue are expected to be negligible.

We have closely monitored the potential impact of the Year 2000 issue on
insurance coverages written by our property and casualty subsidiaries. To date,
we have received a relatively small number of claims related to the Year 2000
issue. The policies under which such claims have been made include provisions
that we believe either preclude or limit the amount of coverage. For these
reasons, management does not believe at this time that there is a likelihood of
a significant adverse financial impact from Year 2000 related losses.
Nevertheless, it is possible that Year 2000 related losses may emerge that would
adversely affect operating results in future periods.

CAPITAL RESOURCES

In February 1994, the Board of Directors authorized the repurchase of up to
10,000,000 shares of common stock. Through March 1997, the Corporation had
repurchased 6,851,600 shares under the 1994

29
30

share repurchase authorization. In March 1997, the Board of Directors replaced
the 1994 authorization with a new authorization to repurchase up to 17,500,000
shares of common stock. In July 1998, the Board of Directors authorized the
repurchase of up to an additional 12,500,000 shares. Through December 31, 1999,
the Corporation had repurchased 20,591,600 shares under the 1997 and 1998
authorizations. As of December 31, 1999, 9,408,400 shares remained under the
current share repurchase authorizations. In the aggregate, the Corporation
repurchased 2,596,700 shares in open-market transactions in 1999 at a cost of
$145 million, 8,203,000 shares in 1998 at a cost of $609 million and 12,940,500
shares in 1997 at a cost of $828 million.

The Corporation filed a shelf registration statement which the Securities
and Exchange Commission declared effective in September 1998, under which up to
$600 million of various types of securities may be issued by the Corporation or
Chubb Capital Corporation, a wholly owned subsidiary. No securities have been
issued under this registration statement.

The Corporation has outstanding $300 million of unsecured 6.15% notes due
in 2005 and $100 million of unsecured 6.60% debentures due in 2018. Chubb
Capital has outstanding $100 million of unsecured 6 7/8 % notes due in 2003. The
Chubb Capital notes are guaranteed by the Corporation.

The long term debt obligations of Executive Risk remained in place
subsequent to the acquisition. 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 two credit agreements with a group of banks that
provide for unsecured borrowings of up to $500 million in the aggregate. The
$200 million short term revolving credit facility, which was to have terminated
on July 7, 1999, was extended to July 5, 2000, and may be renewed or replaced.
The $300 million medium term revolving credit facility terminates on July 11,
2002. On the respective termination dates, any loans then outstanding become
payable. There have been no borrowings under these agreements. These facilities
are available for general corporate purposes and to support Chubb Capital's
commercial paper borrowing arrangement.

CHANGE IN ACCOUNTING PRINCIPLES

In 1999, the Corporation adopted Statement of Position (SOP) 98-1,
Accounting for the Costs of Computer Software Developed or Obtained for Internal
Use, which was issued by the American Institute of Certified Public Accountants.
This SOP requires that certain costs incurred to develop or obtain computer
software for internal use should be capitalized and amortized over the
software's expected useful life. Prior to 1999, we expensed all development
costs of internal use computer software. The SOP has been applied prospectively.
The adoption of SOP 98-1 increased the Corporation's net income in 1999 by $17
million. The effect on net income will decrease in future years as the new
method of accounting is phased in.

For the purposes of complying with the amendments to the rules governing
Form S-8 (effective July 13, 1990) under the Securities Act of 1933, the
undersigned registrant hereby undertakes as follows, which undertaking shall be
incorporated by reference into registrant's Registration Statements on Form S-8
Nos. 33-29185 (filed June 7, 1989), 33-30020 (filed July 18, 1989), 33-49230

S-4 on Form S-8 No. 333-73073 (filed July 19, 1999):

Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing
provisions, or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities
(other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification
by it is against public policy as expressed in the Act and will be
governed by the final adjudication of such issue.
