                              THE CHUBB CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1)  General

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

            The amounts included in this report are unaudited but include those
      adjustments, consisting of normal recurring items, which management
      considers necessary for a fair presentation. These consolidated financial
      statements should be read in conjunction with the consolidated financial
      statements and related notes in the Notes to Consolidated Financial
      Statements included in the Corporation's 2004 Annual Report on Form 10-K.

2)  Investments

            Short term investments, which have an original maturity of one year
      or less, are carried at amortized cost which approximates market value.
      Fixed maturities classified as held-to-maturity are carried at amortized
      cost. Fixed maturities classified as available-for-sale and equity
      securities are carried at market value as of the balance sheet date.

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

3)  Income Tax

            In connection with the sale of a subsidiary a number of years ago,
      the Corporation agreed to indemnify the buyer for certain pre-closing tax
      liabilities. During the first three months of 2005, this obligation was
      settled with the purchaser. Accordingly, the income tax liability was
      reduced, which resulted in the recognition of a tax benefit of $22
      million.

4)  Segments Information

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

            The reporting format for property and casualty underwriting results
      by business unit has been changed to more closely reflect the way the
      business is now managed. Prior period amounts have been reclassified to
      conform with the new presentation.

            The property and casualty underwriting operations consist of four
      separate business units: personal insurance, commercial insurance,
      specialty insurance and reinsurance assumed. The personal segment targets
      the personal insurance market. The personal classes include automobile,
      homeowners and other personal coverages. The commercial segment includes
      those classes of business that are generally available in broad markets
      and are of a more commodity nature. Commercial classes include multiple
      peril, casualty, workers' compensation and property and marine. The
      specialty segment includes those classes of business that are available in
      more limited markets since they require specialized underwriting and claim
      settlement. Specialty classes include professional liability coverages and
      surety. Reinsurance assumed includes the business produced by Chubb Re.

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

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

                                                                          Page 7


            Revenues and income before income tax of the operating segments were
      as follows:

-     our ability to retain existing business;

-     our expectations with respect to cash flow projections and
      investment income and with respect to other income;

-     the adequacy of loss reserves including:

            -     our expectations relating to reinsurance recoverables;

            -     the effects of proposed asbestos liability legislation,
                  including the impact of claims patterns arising from the
                  possibility of legislation and those that may arise if
                  legislation is not passed;

            -     our estimates relating to ultimate asbestos liabilities; 

            -     the impact from the bankruptcy protection sought by various
                  asbestos producers and other related businesses;

            -     the willingness of parties, including us, to settle disputes;

            -     developments in judicial decisions or regulatory or
                  legislative actions relating to coverage and liability for

CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

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

EXECUTIVE SUMMARY

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

      -     Net income was $470 million in the first quarter of 2005 compared
            with $361 million in the comparable period of 2004.

      -     Premium growth was 1% in the first quarter of 2005, reflecting
            modest growth in our insurance business and a decrease in written
            premiums in our reinsurance assumed business. We maintained
            underwriting discipline in a more competitive market environment.
            Rates were generally stable in most classes of business.

      -     Underwriting results were highly profitable as evidenced by the
            combined loss and expense ratio of 89.4% in the first quarter of
            2005 compared with 92.6% in the corresponding 2004 quarter.

      -     Property and casualty investment income after taxes increased by 14%
            in the first quarter of 2005.

                                                                         Page 12

     Net income included realized investment gains after tax of $29 million in
the first quarter of 2005 and $53 million in the first quarter of 2004.
Decisions to sell securities are governed principally by considerations of
investment opportunities and tax consequences. As a result, realized gains and
losses on the sale of investments may vary significantly from period to period.

      Earnings from our property and casualty business were significantly higher
in the first quarter of 2005 compared with the same period of 2004.

      Underwriting income was substantially higher in the first quarter of 2005
due primarily to improvement in our personal insurance business. Our commercial
insurance business produced exceptionally strong results in the first quarter of
2005 and 2004.

      Investment income also increased significantly in the first quarter of
2005 compared with 2004.

      The profitability of the property and casualty insurance business depends
on the results of both underwriting operations and investments. We view these as
two distinct operations. The underwriting functions are managed separately from
the investment function. Accordingly, in assessing our performance, management
evaluates underwriting results separately from investment results.

  UNDERWRITING RESULTS

      We evaluate the underwriting results of our property and casualty
insurance business in the aggregate and also for each of our business units.

      The combined loss and expense ratio, expressed as a percentage, is the key
measure of underwriting profitability traditionally used in the property and
casualty insurance business. Management evaluates the performance of our
underwriting operations and of each of our business units using, among other
measures, the combined loss and expense ratio calculated in accordance with
statutory accounting principles. It is the sum of the ratio of losses and loss
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.

      Statutory accounting principles applicable to property and casualty
insurance companies differ in certain respects from generally accepted
accounting principles (GAAP). Under statutory accounting principles, policy
acquisition and other underwriting expenses are recognized immediately, not at
the time premiums are earned. Management uses underwriting results determined in
accordance with GAAP, among other measures, to assess the overall performance of
our underwriting operations. To convert underwriting results to a GAAP basis,
policy acquisition expenses are deferred and amortized over the period in which
the related premiums are earned. Underwriting income determined in accordance
with GAAP is defined as premiums earned less losses and loss expenses incurred
and GAAP underwriting expenses incurred.

  Net Premiums Written

      Property and casualty net premiums written were $3.1 billion in the first
quarter of 2005, an increase of 1% compared with the first quarter of 2004.

      Insurance premiums grew 3% in the first quarter of 2005 compared with the
same period of 2004. Over 75% of our insurance premiums are written in the
United States. Insurance premiums in the U.S. grew by 1% in the first quarter.
Insurance premiums outside the U.S. grew 7% on a reported basis and 3% in local
currencies.

                                                                         Page 14


      We experienced modest premium growth in the first quarter in each of our
insurance business units, while maintaining underwriting discipline in a more
competitive market environment. Rates were generally stable in most classes of
business. We continued to retain a high percentage of our existing customers and
to find opportunities to write new business at adequate rates. We expect that
pricing pressure will continue throughout 2005.

      As expected, reinsurance assumed premiums generated by Chubb Re decreased
by 12% in the first quarter compared with the same period of 2004.

  Reinsurance Ceded

      Our premiums written are net of amounts ceded to reinsurers who assume a
portion of the risk under the insurance policies that are subject to the
reinsurance. After several years of significant price increases, the cost of
reinsurance in the marketplace has leveled off. However, the reinsurance
capacity for certain coverages, such as terrorism, continues to be limited and
expensive.

      We expect our reinsurance costs in 2005 to be less than those in 2004. In
January 2005, we discontinued our executive protection per risk treaty.
Underwriting actions we have taken in recent years have resulted in lower
average limits on those large risks we write, which we believe made this treaty
no longer economical. On our casualty clash treaty, which operates like a
catastrophe treaty, we increased our retention from $50 million to $75 million.
This treaty now provides $125 million of coverage in excess of $75 million per
insured event. We did not renew a high excess surety per risk treaty as we
believe the cost was not justified.

      Our property reinsurance program was renewed in April 2005. On the
property per risk treaty, our retention remained at $15 million. Our property
catastrophe treaty for events in the United States was modified to increase the
coverage in the northeastern part of the country by $100 million. The program
now provides coverage of approximately 85% of losses between $250 million and
$1.25 billion, with additional coverage of 80% of losses between $1.25 billion
and $1.6 billion in the northeastern part of the country. Our property
catastrophe treaty for events outside the United States was modified to increase
our retention from $25 million to $50 million.

      Our property reinsurance treaties generally contain terrorism exclusions.
Since September 2001, we have changed our underwriting protocols to address
terrorism and the limited availability of terrorism reinsurance. However, given
the uncertainty of the potential threats, we cannot be sure that we have
addressed all the possibilities.

      It is unclear at this time whether Congress will reauthorize the Terrorism
Risk Insurance Act of 2002 (TRIA) for periods subsequent to December 31, 2005.
Regardless of whether or not TRIA is extended, we will continue to manage this
type of catastrophic risk by monitoring and controlling terrorism risk
aggregations. Nevertheless, given the unpredictable nature of terrorism, its
targets, frequency and severity as well as the limited terrorism coverage in our
reinsurance program, our future operating results could be more volatile.

  Profitability

      Underwriting results were highly profitable in the first quarter of both
2005 and 2004. Our combined loss and expense ratio was 89.4% in the first
quarter of 2005 compared with 92.6% in 2004.

                                                                         Page 15


      The loss ratio was 60.6% for the first quarter of 2005 compared with 62.5%
in 2004. The improvement in the loss ratio in 2005 was due to lower catastrophe
losses. Catastrophe losses during the first quarter of 2005 amounted to $20
million which represented 0.6 of a percentage point of the loss ratio compared
with $97 million or 3.5 percentage points in 2004.

      Our expense ratio decreased to 28.8% for the first quarter of 2005 from
30.1% in 2004 due to lower contingent commissions as well as a modest decrease
in overhead expenses as we continued to make progress in reducing our cost
structure.

      We have not yet concluded the negotiations with our brokers and agents on
2005 commission arrangements. At this point, we continue to expect that total
producer compensation in 2005 will be at about 2004 levels and we accrued at
that rate in the first quarter of 2005. The lower contingent commissions in the
first quarter of 2005 compared with the same period in 2004 was due largely to
the fact that we accrued contingent commissions in the first quarter of 2004 at
a higher rate in anticipation of high premium growth during 2004.

  REVIEW OF UNDERWRITING RESULTS BY BUSINESS UNIT

      The reporting format for property and casualty underwriting results by
business unit has been changed to more closely reflect the way the business is
now managed. Prior period amounts have been reclassified to conform with the new
presentation.

      The changes to the reporting format are as follows:

      Personal Insurance

      -     Valuable articles results, which have been included in other
            personal, are now included in homeowners.

      -     Accident results, which have been included in other specialty, are
            now included in other personal.

      Commercial Insurance

      -     Commercial insurance results for financial institutions, which have
            been included in financial institutions results in specialty
            insurance, are now included in the appropriate commercial insurance
            lines.

      Specialty Insurance

      -     Executive protection results are now combined with the professional
            liability and financial fidelity results for financial institutions
            into a new professional liability line. Financial institutions
            results are no longer reported separately.

      -     Surety results, which have been included in other specialty, are now
            reported separately within specialty insurance.

      Reinsurance Assumed

      -     Reinsurance assumed results, which have been included in other
            specialty, are now reported as a separate business unit.

                                                                         Page 16


      Underwriting results during 2005 and 2004 by business unit were as
follows:



                                  Net Premiums Written         Combined Loss and

  Personal Insurance

      Premiums from personal insurance coverages, which represent 25% of total
premiums written, increased by 5% in the first quarter of 2005 compared with the
same quarter in 2004. Premium growth was driven by our homeowners business due
to increased insurance-to-value and, to a lesser extent, modestly higher rates
and an increase in the in force policy count. The low growth in personal
automobile premiums was due to our maintaining underwriting discipline in a more
competitive marketplace. The decrease in other personal premiums was
attributable to our accident business, due in large part to the non-renewal of
one large account.

      Our personal insurance business produced highly profitable underwriting
results in the first quarter of 2005 compared with modestly profitable results
in 2004. The combined loss and expense ratio was 84.5% in the first quarter of
2005 compared with 97.5% in 2004. Excluding catastrophe losses, the combined
ratio was 83.1% and 87.3% in the first quarter of 2005 and 2004, respectively.

      Homeowners results were highly profitable in 2005 compared with modestly
unprofitable results in 2004. The improvement was due to lower catastrophe
losses as well as better pricing and contract wording changes related to mold
damage that we have implemented over the past few years. Catastrophe losses
represented 2.6 and 16.8 percentage points of the loss ratio for this class in
the first quarter of 2005 and 2004, respectively. The catastrophe losses in 2004
were primarily from severe winter weather in the northeastern part of the United
States where we have a significant market presence.

                                                                         Page 17


      Our personal automobile business produced similarly profitable results in
2005 and 2004. This business continues to experience stable claim frequency and
severity. Other personal coverages, which include excess liability, yacht and
accident insurance, produced highly profitable results in both years due to
favorable loss experience.

  Commercial Insurance

      Premiums from commercial insurance, which represent 44% of our total
writings, increased by 2% in the first quarter of 2005 compared with the same
period a year ago. Rates were flat in the first quarter of 2005 compared with
the first quarter of 2004 as we continued to experience more competition in the
marketplace. Retention levels in the first quarter of 2005 were slightly higher
than those in the comparable period of 2004. New business volume was down from
2004 levels as competitors have worked to retain their better accounts. We
continued to get favorable terms and conditions on business written. We expect
that rates will be relatively stable through the remainder of 2005.

      Our commercial insurance business produced highly profitable underwriting
results in the first quarter of 2005 and 2004. The combined loss and expense
ratio was 84.0% for the first quarter of 2005 compared with 82.9% in 2004. These
results reflect the cumulative effect of price increases, better terms and
conditions and more stringent risk selection in recent years. Results in both
years also benefited from low property losses.

      Multiple peril results were highly profitable in 2005 and 2004. The
property component of this business was exceptionally profitable in both years.
Catastrophe losses represented 0.5 of a percentage point of the loss ratio for
this class in the first quarter of 2005 compared with 3.9 percentage points in
2004.

      Our casualty business produced less profitable results in 2005 compared
with 2004. The primary liability and automobile components of this business were
highly profitable in both years but more so in 2004. The excess liability
component produced breakeven results in 2005 compared with modestly profitable
results in 2004.

      Workers' compensation results were highly profitable in 2005 and 2004 due
in large part to our disciplined risk selection during the past several years.

      Property and marine results were highly profitable in both years due to
few severe losses. Catastrophe losses represented 1.3 percentage points of the
loss ratio for this class in 2005 compared with 3.7 percentage points in 2004.

  Specialty Insurance

      Premiums from specialty insurance, which represent 23% of our total
writings, increased by 1% in the first quarter of 2005 compared with the same
period a year ago. Premium growth in the professional liability classes of
business was constrained by the competitive pressure on rates and our commitment
to maintain underwriting discipline. Rates for most classes were generally
stable. However, rates in the for-profit directors and officers liability
component were down, particularly for large public companies. New business
volume in 2005 was similar to 2004 levels. In line with our strategy in recent
years, we continue to focus on small and middle market publicly traded and
privately held companies. Retention levels in 2005 were also similar to 2004
levels. We continued to get adequate rates and favorable terms and conditions on
both new business and renewals.

                                                                         Page 18


      Our specialty insurance business produced unprofitable underwriting
results in the first quarter of 2005 and 2004. The combined loss and expense
ratio was 105.0% for the first quarter of 2005 compared with 103.7% in 2004.

      Our professional liability results improved in 2005 but were modestly
unprofitable. The improvement in 2005 was due to the cumulative effect of price
increases, lower policy limits and better terms and conditions in recent years.
Results in 2005 and 2004 were adversely affected by unfavorable development on
loss reserves related to accident years 2002 and prior. The adverse development
was due in large part to claims that have arisen due to corporate failures and
allegations of management misconduct and accounting irregularities. The fidelity
component of this business was highly profitable in both years but more so in
2005. Fidelity results in 2004 were adversely affected by several large losses
outside the United States.

      Surety results were highly unprofitable in 2005 compared with highly
profitable results in 2004. Our surety business tends to be characterized by
infrequent but potentially high severity losses. The unprofitable results in
2005 were due to one $60 million loss.

  Reinsurance Assumed

      Premiums from our reinsurance assumed business generated by Chubb Re,
which represent 8% of total premiums written, decreased by 12% in the first
quarter of 2005 compared with the first quarter of 2004. The decrease in
premiums was expected as there were fewer attractive opportunities in the
reinsurance market.

      Our reinsurance assumed business was highly profitable in the first
quarter of 2005 and 2004, but more so in 2005. The combined loss and expense
ratio was 88.0% in the first quarter of 2005 compared with 93.1% in 2004. The
improvement in 2005 was largely the result of the favorable settlement of one
loss.

  LOSS RESERVES

      Unpaid losses and loss expenses, also referred to as loss reserves, are
the largest liability of our property and casualty subsidiaries.

      Our loss reserves include the accumulation of individual case estimates
for claims that have been reported and estimates of claims that have been
incurred but not reported as well as estimates of the expenses associated with
settling all reported and unreported claims. Estimates are based upon past loss
experience modified for current trends as well as prevailing economic, legal and
social conditions. Our loss reserves are not discounted to present value.

      We continually review our loss reserves using a variety of statistical and
actuarial techniques. We update the reserves as loss experience develops,
additional claims are reported and new information becomes available. Any
changes in estimates are reflected in operating results in the period in which
the estimates are changed.

                                                                         Page 19


      Our loss reserves include significant amounts related to asbestos and
toxic waste claims and the September 11, 2001 attack. The components of our loss
reserves were as follows:

      Loss reserves, net of reinsurance recoverable, increased by $510 million
during the first quarter of 2005. The loss reserves related to asbestos and
toxic waste claims and the September 11 attack are significant components of our
total loss reserves, but they distort the growth trend in our loss reserves.
Excluding such loss reserves, our loss reserves, net of reinsurance recoverable,
increased by $563 million during the first quarter of 2005.

      The components of our net loss reserves were as follows:

      Loss reserves for each of our business units increased in the first
quarter of 2005, with the most significant increases in the long tail liability
classes of business within commercial and specialty insurance and reinsurance
assumed. The relatively small increase in personal insurance loss reserves was
due in part to a $23 million reduction in unpaid claims related to catastrophes.

                                                                         Page 20


      Based on all information currently available, we believe that the
aggregate loss reserves of our property and casualty subsidiaries at March 31,
2005 were adequate to cover claims for losses that had occurred, including both
those known to us and those yet to be reported. In establishing such reserves,
we consider facts currently known and the present state of the law and coverage
litigation. However, given the judicial decisions and legislative actions that
have broadened the scope of coverage and expanded theories of liability in the
past and the possibilities of similar interpretations in the future,
particularly as they relate to asbestos claims and, to a lesser extent, toxic
waste claims, it is possible that management's estimate of the ultimate
liability for losses that had occurred as of March 31, 2005 may increase in
future periods. Such increases in estimates could have a material adverse effect
on the Corporation's future operating results. However, management does not
expect that any such increases would have a material effect on the Corporation's
consolidated financial condition or liquidity.

  INVESTMENT RESULTS

      Property and casualty investment income before taxes increased by 13% in
the first quarter of 2005 compared with the same period in 2004. Growth was due
to an increase in invested assets since the first quarter of 2004. The increase
in invested assets was due to substantial cash flow from operations over the
period. Growth in investment income in 2005 was dampened, however, by lower
available reinvestment rates on fixed maturities that matured over the past
year.

      The effective tax rate on investment income was 19.5% in the first quarter
of 2005 compared with 20.1% in the comparable period in 2004. The effective tax
rate fluctuates as a result of our holding a different proportion of our
investment portfolio in tax-exempt securities during each period.

      On an after-tax basis, property and casualty investment income increased
by 14% in the first quarter of 2005. Management uses property and casualty
investment income after-tax, a non-GAAP financial measure, to evaluate its
investment performance because it reflects the impact of any change in the
proportion of the investment portfolio invested in tax-exempt securities and is
therefore more meaningful for analysis purposes than investment income before
income tax.

CHUBB FINANCIAL SOLUTIONS

      Chubb Financial Solutions (CFS) was organized in 2000 to develop and
provide customized products to address specific financial needs of corporate
clients. CFS operated through both the capital and insurance markets.

      In April 2003, the Corporation announced its intention to exit CFS's
non-insurance business and to run-off the existing financial products portfolio.

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

                                                                         Page 21


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

      The fair value of our credit default swaps is subject to fluctuations
arising from, among other factors, changes in credit spreads, the financial
ratings of referenced asset-backed securities, actual credit events reducing
subordination, credit correlation within a portfolio, anticipated recovery rates
related to potential defaults and changes in interest rates. Changes in fair
value are included in income in the period of the change.

      The non-insurance business of CFS produced breakeven results in the first
quarter of 2005 compared with a loss before taxes of $14 million in the
comparable period of 2004. The loss in the first quarter of 2004 was primarily
related to the termination during the quarter of CFS's obligations under certain
portfolio credit default swaps.

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

      The notional amount of CFS's credit default swaps was $8.2 billion at
March 31, 2005. Our realistic loss exposure is a very small portion of the $8.2
billion notional amount as our position is senior to subordinated interests of
$5.3 billion in the aggregate. In addition, using our internal ratings models,
we estimate that the credit ratings of the individual portfolio credit default
swaps at March 31, 2005 were AAA.

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

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

      In the fourth quarter of 2003, CFS terminated two asset-backed portfolio
credit default swaps that had experienced deterioration in credit quality and
simultaneously entered into a new contract that guaranteed principal and
interest obligations. The Corporation has guaranteed CFS's obligations under the
new contract. CFS's potential payment obligation extends to the date when the
last of the underlying obligations expires. At March 31, 2005, the remaining
notional amount of referenced securities was $1.8 billion. Under the new
agreement, CFS's maximum potential payment obligation is limited to $500 million
regardless of the amount of losses that might be incurred on the $1.8 billion of
referenced securities. Moreover, if losses are incurred, CFS's payment
obligations are limited to an extended payment schedule under which no payment
would be due until 2010 at the earliest.

      CFS established a liability of $186 million related to the principal and
interest contract, which represented the estimated fair value of the guarantee
at its inception. The principal and interest guarantee is not a derivative
contract. Therefore, the liability related to this contract is not
marked-to-market each period and remained at $186 million at March 31, 2005. Due
to the nature of the guarantee, we will reduce this liability only upon either
the expiration or settlement of the guarantee. If actual losses are incurred, a
liability for the losses will be established, and a portion of the guarantee
liability will be released. The amount released will depend on our evaluation of
expected ultimate loss experience.

CORPORATE AND OTHER

      Corporate and other includes investment income earned on corporate
invested assets, interest expense and other expenses not allocated to the
operating subsidiaries and the results of our real estate and other
non-insurance subsidiaries. It also includes income from our investment in
Allied World Assurance Company, Ltd.

      Corporate and other produced a loss before taxes of $62 million in the
first quarter of 2005 compared with a loss of $33 million in the first quarter
of 2004. The significantly higher loss in 2005 was due to the recognition of a
real estate impairment loss, which is discussed below. Results in the first
quarter of 2004 included a loss at The Chubb Institute, Inc., our post-secondary
educational subsidiary, which we sold in the third quarter of 2004.

  REAL ESTATE

      Real estate operations resulted in a loss before taxes of $43 million in
the first quarter of 2005 compared with a loss of $5 million in the same period
in 2004, which amounts are included in the corporate and other results.

      During the first quarter of 2005, we committed to a plan to sell a parcel
of land in New Jersey that we had previously intended to hold and develop. The
decision to sell the property was based on our assessment of the current real
estate market and our concern about zoning issues. As a result of our decision
to sell this property in the near term, we reassessed the recoverability of its
carrying value. Based on our reassessment, we recognized an impairment loss of
$43 million to reduce the carrying value of the property to its estimated fair
value.

                                                                         Page 23


      In addition to the aforementioned parcel of land that we plan to dispose
of in the near term, we own approximately $190 million of land that we expect
will be developed in the future. Our real estate assets also include
approximately $155 million of commercial properties and land parcels under
lease, of which $22 million relates to a variable interest entity in which we
are the primary beneficiary.

      The recoverability of the carrying value of our real estate assets, other
than the parcel of land that we plan to dispose of in the near term, is assessed
based on our ability to fully recover costs through a future revenue stream. The
assumptions used reflect future improvement in demand for office space, an
increase in rental rates and the ability and intent to obtain financing in order
to hold and develop such remaining properties and protect our interests over the
long term. Management believes that it has made adequate provisions for
impairment of real estate assets. However, if the assets are not sold or
developed or if leased properties do not perform as presently contemplated, it
is possible that additional impairment losses may be recognized that would have
a material adverse effect on the Corporation's results of operations.

      Of the net realized gains on sales of equity securities, $47 million and
$46 million in the first quarter of 2005 and 2004, respectively, related to our
share of gains recognized by investment partnerships in which we have an
interest.

      We regularly review those invested assets whose fair value is less than
cost to determine if an other than temporary decline in value has occurred. In
evaluating whether a decline in value of any investment is other than temporary,
we consider various quantitative and qualitative factors including the length of
time and the extent to which the fair value has been less than the cost, the
financial condition and near term prospects of the issuer, whether the issuer is
current on contractually obligated interest and principal payments, and our
intent and ability to hold the investment for a period of time sufficient to
allow us to recover our cost. If a decline in the fair value of an individual
security is deemed to be other than temporary, the difference between cost and
estimated fair value is charged to income as a realized investment loss. The
fair value of the investment becomes its new cost basis. There were no other
than temporary impairment writedowns in the first quarter of 2005 or 2004.

                                                                         Page 24


INCOME TAXES

      In connection with the sale of a subsidiary a number of years ago, we
agreed to indemnify the buyer for certain pre-closing tax liabilities. During
the first quarter of 2005, we settled this obligation with the purchaser.
Accordingly, we reduced our income tax liability, which resulted in the
recognition of a benefit of $22 million.

CAPITAL RESOURCES AND LIQUIDITY

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

  CAPITAL RESOURCES

      Capital resources provide protection for policyholders, furnish the
financial strength to support the business of underwriting insurance risks and
facilitate continued business growth. At March 31, 2005, the Corporation had
shareholders' equity of $10.4 billion and total debt of $2.8 billion.

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

      In June 2003, a shelf registration statement that the Corporation filed in
March 2003 was declared effective by the Securities and Exchange Commission.
Under the registration statement, up to $2.5 billion of various types of
securities may be issued. At March 31, 2005, the Corporation had approximately
$650 million remaining under the shelf registration statement.

      In July 1998, the Board of Directors authorized the repurchase of up to
12,500,000 shares of the Corporation's common stock. The authorization has no
expiration. The Corporation made no share repurchases during the first quarter
of 2005. As of March 31, 2005, 3,287,100 shares remained under the share
repurchase authorization.

  RATINGS

      The Corporation and its insurance subsidiaries are rated by major rating
agencies. These ratings reflect the rating agency's opinion of our financial
strength, operating performance, strategic position and ability to meet our
obligations to policyholders.

      Ratings are an important factor in establishing our competitive position
in the insurance markets. There can be no assurance that our ratings will
continue for any given period of time or that they will not be changed.

                                                                         Page 25


      It is possible that positive or negative ratings actions by one or more of
the rating agencies may occur in the future. If our ratings were downgraded, the
Corporation may incur higher borrowing costs and may have more limited means to
access capital. In addition, reductions in our ratings could adversely affect
the competitive position of our insurance operations, including a possible
reduction in demand for our products in certain markets.

  LIQUIDITY

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

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

      New cash from operations available for investment by the property and
casualty subsidiaries was approximately $900 million in the first quarter of
2005 compared with $825 million in the same period in 2004.

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

      The Corporation's liquidity requirements in the past have been met by
dividends from its property and casualty subsidiaries and the issuance of
commercial paper and debt and equity securities. It is expected that our
liquidity requirements in the future will be met by these sources of funds or,
if necessary, borrowings from our credit facilities.

INVESTED ASSETS

      The main objectives in managing our investment portfolios are to maximize
after-tax investment income and total investment returns while minimizing credit
risks in order to provide maximum support to the insurance underwriting
operations. Investment strategies are developed based on many factors including
underwriting results and our resulting tax position, regulatory requirements,
fluctuations in interest rates and consideration of other market risks.
Investment decisions are centrally managed by investment professionals based on
guidelines established by management and approved by the boards of directors.

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

      In the first quarter of 2005, we invested new cash in tax-exempt bonds 
and, to a lesser extent, taxable bonds and equity securities. Taxable bonds we
invested in were primarily mortgage-backed securities and corporate bonds. Our
objective is to achieve the appropriate mix of taxable and tax-exempt securities
in our portfolio to balance both investment and tax strategies.

                                                                         Page 26


      The unrealized appreciation before tax of investments carried at market
value, which includes fixed maturities classified as available-for-sale and
equity securities, was $545 million and $961 million at March 31, 2005 and
December 31, 2004, respectively. Such unrealized appreciation is reflected in a
separate component of other comprehensive income, net of applicable deferred
income tax.

      The unrealized market appreciation before tax of those fixed maturities
carried at amortized cost was $17 million at March 31, 2005 and $21 million at
December 31, 2004. Such unrealized appreciation was not reflected in the
consolidated financial statements.

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

                                                                         Page 27


Item 4 - Controls and Procedures

      As of March 31, 2005, an evaluation of the effectiveness of the design and
operation of the Corporation's disclosure controls and procedures was performed
under the supervision and with the participation of the Corporation's
management, including the chief executive officer and chief financial officer.
Based on that evaluation, the chief executive officer and chief financial
officer concluded that the Corporation's disclosure controls and procedures were
effective as of the evaluation date.

      During the three month period ended March 31, 2005, there were no changes
in internal control over financial reporting that have materially affected, or
are reasonably likely to materially affect, the Corporation's internal control
over financial reporting.

                                                                         Page 28
