                              THE CHUBB CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1)     General

              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 2000 Annual Report to Shareholders.

2)     Adoption of New Accounting Pronouncements

              Effective January 1, 2001, the Corporation adopted Statement of
       Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative
       Instruments and Hedging Activities, and SFAS No. 138, Accounting for
       Certain Derivative Instruments and Certain Hedging Activities. SFAS No.
       133 establishes accounting and reporting standards for derivative
       instruments and hedging activities, and SFAS No. 138 provides additional
       guidance related to accounting and reporting for certain derivative
       instruments and hedging activities. SFAS No. 133 requires that all
       derivatives be recognized in the balance sheet as assets or liabilities
       and be measured at fair value. The Statements may not be applied
       retroactively to financial statements of prior periods. Currently, the
       Corporation's use of derivatives is not significant. Thus, the adoption
       of SFAS No. 133 and SFAS No. 138 did not have a significant effect on the
       Corporation's financial position or results of operations.

              Effective April 1, 2001, the Corporation adopted the Emerging
       Issues Task Force (EITF) consensus on Issue No. 99-20, Recognition of
       Interest Income and Impairment on Purchased and Retained Beneficial
       Interests in Securitized Financial Assets. EITF Issue No. 99-20 requires
       that investors in certain asset-backed securities recognize changes in a
       security's estimated yield prospectively. EITF Issue No. 99-20 also
       requires that if the carrying value of any such asset-backed security
       exceeds its current fair value, investors determine whether the excess
       represents an other than temporary decline in value and recognize any
       such decline as a loss in the income statement. The adoption of EITF
       Issue No. 99-20 did not have a significant effect on the Corporation's
       financial position or results of operations.

3)     Accounting Pronouncements Not Yet Adopted

              In June 2001, the Financial Accounting Standards Board (FASB)
       issued SFAS No. 141, Business Combinations, and SFAS No. 142, Goodwill
       and Other Intangible Assets. SFAS No. 141 requires all business
       combinations initiated after June 30, 2001 to be accounted for using the
       purchase method.

              Under SFAS No. 142, goodwill will no longer be amortized but
       rather will be tested at least annually for impairment. The provisions of
       SFAS No. 142 shall be effective for the Corporation for the year
       beginning January 1, 2002. The Statement shall be applied to all goodwill
       recognized in the Corporation's financial statements at that date. SFAS
       No. 142 may not be applied retroactively to financial statements of prior
       periods. The effect of the adoption of SFAS No. 142 on the Corporation's
       financial position or results of operations has not yet been determined.

4)     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 or depreciation of
       investments carried at market value was as follows:

6)     Segments Information

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

              The property and casualty underwriting segments reflect certain
       reclassifications to present results in a manner more consistent with the
       way the business is now managed. Prior period amounts have been restated
       to conform to the new presentation.

PROPERTY AND CASUALTY INSURANCE

       Earnings from our property and casualty business were lower in the first
six months and second quarter of 2001 compared with the same periods of 2000.
The lower earnings in 2001 were due to a deterioration in underwriting results
caused in large part by substantially higher catastrophe losses. Investment
income increased modestly in the first six months of 2001 compared with 2000.
Property and casualty income before taxes amounted to $367.8 million in the
first six months of 2001 and $165.0 million in the second quarter compared with
$397.3 million and $223.9 million, respectively, in 2000.

       Net premiums written were $3.4 billion in the first six months of 2001,
an increase of 8.0% compared with the same period in 2000. Net premiums written
were $1.6 billion in the second quarter of 2001, an increase of 7.0% over the
comparable period of 2000. U.S. premiums grew 8.2% in the first six months of
2001 and 6.1% in the second quarter. Substantial premium growth was achieved
outside the United States in 2001. Non-U.S. premiums grew about 16% in local
currencies in both the first six months and second quarter. However, due to the
strength of the U.S. dollar, reported non-U.S. premium growth was 7.1% in the
first six months of 2001 and 11.5% in the second quarter.

       Premium growth in personal lines remained strong. Competition in the
worldwide marketplace has made profitable premium growth difficult in the
commercial classes, which include multiple peril, casualty, workers'
compensation and property and marine. However, our strategy to increase the
pricing in these classes continued to show success, resulting in premium growth
of 6.4% for these classes in the second quarter of 2001 compared with flat
premiums in the first quarter. Premium growth in the specialty lines was
restricted in 2001, particularly in the second quarter, primarily due to the
lack of growth in our executive protection business caused by our writing fewer
multi-year policies as well as our pricing and pruning initiative.

       Underwriting results were unprofitable in the first six months and second
quarter of 2001 compared with near breakeven results in the first six months of
2000 and profitable results in the second quarter of 2000. Our combined loss and
expense ratio was 101.7% in the first six months of 2001 and 103.5% in the
second quarter compared with 100.2% and 98.6%, respectively, in 2000.

       The loss ratio was 68.5% for the first six months of 2001 and 70.0% for
the second quarter compared with 67.5% and 65.9%, respectively, in the prior
year. The loss ratios in both years, but more so in 2001, were adversely
affected by catastrophe losses. Catastrophe losses during the first six months
of 2001 amounted to $91.8 million which represented 2.8 percentage points of the
loss ratio compared with $54.6 million or 1.8 percentage points in 2000.
Catastrophe losses for the second quarter of 2001 amounted to $80.3 million or
4.9 percentage points of the loss ratio compared with $24.3 million or 1.6
percentage points in 2000. The catastrophe losses in both years resulted
primarily from storms in the United States, particularly tropical storm Allison
in the second quarter of 2001.

       Our expense ratio was 33.2% for the first six months of 2001 and 33.5%
for the second quarter compared with 32.7% for both periods in the prior year.
The increase in the expense ratio in 2001 was due to overhead expenses growing
at a higher rate than written premiums as well as slightly higher commission
expenses.

  PERSONAL INSURANCE

       Premiums from personal insurance coverages, which represent 28% of the
premiums written by our property and casualty subsidiaries, increased by 15.0%
in the first six months of 2001 and 16.0% in the second quarter compared with
the similar periods in 2000. Our in-force policy count for automobile,
homeowners and other personal coverages continued to grow significantly.

       Our personal insurance business produced modestly unprofitable
underwriting results in 2001 compared with profitable results in 2000. The
combined loss and expense ratios were 102.1% for the first six months of 2001
and 103.4% for the second quarter compared with 95.8% and 94.1%, respectively,
in 2000.

       Homeowners results were unprofitable in both years, but more so in 2001.
The deterioration in 2001 was due to a higher frequency of non-catastrophe
losses, particularly large losses, as well as rate deficiencies in a number of
states. Catastrophe losses represented 7.0 percentage points of the loss ratio
for this class in the first six months of 2001 and 11.2 percentage points in the
second quarter compared with 11.7 percentage points and 10.4 percentage points,
respectively, in 2000. Homeowners results outside the United States improved in
2001 but remained unprofitable as we are still building the critical mass
necessary to absorb the costs of operating the franchise.

       Our automobile business produced somewhat less profitable results in 2001
compared with 2000 due in part to higher catastrophe losses in the second
quarter.

       Other personal coverages, which include insurance for personal valuables
and excess liability, produced highly profitable results in both years due to
continued favorable loss experience.

  COMMERCIAL INSURANCE

       Premiums from commercial insurance, which represent 36% of our total
writings, increased by 3.0% in the first six months of 2001 and 6.4% in the
second quarter compared with the similar periods in 2000. In late 1998, we put
in place a strategy to renew good business at adequate prices and not renew
underperforming accounts where we could not attain price adequacy. The increase
in premiums in the second quarter of 2001 was due to the near completion of the
pruning process. Retention levels in the first six months of 2001 improved
modestly from year ago levels but remained below historical levels. On the
business that was renewed, rate increases remained firm but the level of rate
increases flattened in the second quarter. Renewal rates in the U.S. were up
approximately 15% in the quarter, the same increase as in the first quarter.

       Our commercial insurance underwriting results remained unprofitable in
the first six months of 2001 but showed significant improvement compared with
2000, despite substantially higher catastrophe losses. The combined loss and
expense ratio was 109.6% for the first six months of 2001 and 112.8% for the
second quarter compared with 113.2% and 110.4%, respectively, in 2000. Results
improved in all segments of this business other than property and marine. Such
improvement was due in large part to the cumulative effect of the pricing
increases and more stringent risk selection in recent years.

                                                                      Page 13


       Multiple peril results remained unprofitable in 2001. However, results
improved considerably compared with the results in 2000, primarily in the
liability component of this business. Results in the property component were
similar in the first six months of both years as a reduction in non-catastrophe
losses in 2001 was substantially offset by an increase in catastrophe losses.
Catastrophe losses represented 6.3 percentage points of the loss ratio for this
class in the first six months of 2001 and 11.7 points in the second quarter.
There were virtually no catastrophe losses for this class in the same periods of
2000.

       Results for our casualty business also improved considerably in the first
six months of 2001 compared with the prior year, but remained unprofitable. The
improvement was primarily in the automobile component of the casualty coverages
due to a lower frequency of losses. Results in the primary liability component
also improved. The excess liability component produced unprofitable results in
2001 compared with near breakeven results in 2000. Casualty results were
adversely affected in both years, but more so in 2001, by incurred losses
related to asbestos and toxic waste claims.

       Workers' compensation results were profitable in 2001 compared with
modestly unprofitable results in 2000. The substantial improvement in 2001 was
due to a lower frequency of losses.

       Property and marine results were highly unprofitable in both years, but
more so in 2001. Results in the first six months of both years were adversely
affected by large losses, both in the United States and overseas. The
deterioration in 2001 was due to substantially higher catastrophe losses and a
number of large losses in the second quarter. Results in the second quarter of
2001 included five losses that represented approximately 24 percentage points of
the loss ratio for this class for the quarter. Catastrophe losses represented
9.4 percentage points of the loss ratio for this class in the first six months
of 2001 and 17.7 percentage points in the second quarter compared with 1.9
percentage points and 2.1 percentage points, respectively, in 2000.

  SPECIALTY INSURANCE

       Premiums from specialty commercial insurance, which represent 36% of our
total writings, increased by 8.1% in the first six months of 2001 and 0.3% in
the second quarter compared with the same periods in 2000. Our strategy of
working closely with our customers and our ability to differentiate our products
continue to enable us to renew a considerable percentage of our executive
protection and financial institutions business. Financial institutions had solid
premium growth of 14.2% in the first six months of 2001 and 9.7% in the second
quarter. Executive protection, however, had premium growth of only 3.5% in the
first six months of 2001 with no growth in the second quarter due to our writing
fewer multi-year policies and a slowdown in new business opportunities. In
addition, recent trends in claim severity indicated a need for higher rates and
improved policy terms. As a result, we have implemented a program to increase
the pricing on this business and to not renew accounts where we cannot attain
price adequacy. Executive protection earned premiums increased by 12.8% in the
first six months of 2001 and 11.2% in the second quarter, reflecting higher
rates on business renewed.

       Growth in our other specialty insurance business is significantly
affected by Chubb Re, our reinsurance business that began operations in 1999. In
the first quarter of 2001, premiums written through Chubb Re increased 87%
whereas in the second quarter such premiums were at about the same level as the
comparable period in 2000.

       Our specialty commercial business produced less profitable underwriting
results in 2001 compared with the highly profitable results in 2000. The
combined loss and expense ratio was 93.6% for the first six months of 2001 and
94.7% for the second quarter compared with 89.1% and 90.1%, respectively, in
2000.

       Executive protection results were profitable in 2001 and 2000 on business
worldwide due to favorable development of prior year loss reserves, particularly
in the directors and officers liability and fiduciary liability components.
However, profit margins have narrowed in the most recent accident years.
Employment practice liability results were unprofitable in both years. Executive
protection results in the second quarter of 2001 were also adversely affected by
several large fidelity losses.

       Our financial institutions business also produced profitable results in
2001 and 2000, but more so in 2000. Both years benefited from favorable loss
experience in the fidelity component. Results in 2001 in the standard commercial
business written on financial institutions were adversely affected by one $10
million property loss, net of reinsurance, in the first quarter.

       Results in our other specialty classes were profitable in the first six
months of 2001 compared with unprofitable results in 2000. Results improved in
both our surety and accident lines of business. Surety results in 2000 were
adversely affected by one large loss in the second quarter. Business written
through Chubb Re produced a modest underwriting loss in 2001 and 2000.

  LOSS RESERVES

       Gross loss reserves were $11,929.6 million and $11,904.6 million at June
30, 2001 and December 31, 2000, respectively. Reinsurance recoverables on such
loss reserves were $1,765.0 million and $1,853.3 million at June 30, 2001 and
December 31, 2000, respectively.

       Loss reserves, net of reinsurance recoverable, increased by $113.3
million during the first six months of 2001. Loss reserves for personal
insurance and specialty insurance increased during the period while loss
reserves for commercial insurance decreased by $126.4 million. Such decrease
reflects the significant exposure reductions of the past three years and
improved accident year results.

       Losses incurred related to asbestos and toxic waste claims were $30.3
million in the first six months of 2001 and $14.1 million for the same period in
2000.

  INVESTMENTS

       Investment income after taxes increased by 2.9% in the first six months
of 2001 and 4.0% in the second quarter compared with the same periods in 2000.
The growth in investment income in 2001 was due to an increase in invested
assets since the second quarter of 2000 offset in part by lower investment
yields. The effective tax rate on investment income increased to 16.8% in the
first six months of 2001 from 16.2% in the comparable period in 2000 due to
holding a somewhat larger proportion of our investment portfolio in taxable
fixed income securities.

       During the first six months of 2001, new cash available for investment
was invested in taxable bonds.

       The property and casualty subsidiaries maintain sufficient investments in
highly liquid, short term securities at all times to provide for immediate cash
needs.

CORPORATE AND OTHER

       Corporate and other includes investment income earned on corporate
invested assets, interest expense and other expenses not allocable to the
operating subsidiaries, and the results of our real estate and other
non-insurance subsidiaries. Corporate and other produced a loss before taxes of
$2.5 million in the first six months of 2001 compared with a loss of $10.9
million in the first six months of 2000. The improvement was primarily due to
higher invest-ment income on corporate assets and earnings in the first quarter
from Chubb Financial Solutions, our financial services business that began
operations in 2000. Chubb Financial Solutions produced a modest loss in the
second quarter.

INVESTMENT GAINS AND LOSSES

       Decisions to sell securities are governed principally by considerations
of investment opportunities and tax consequences. As a result, realized
investment gains and losses may vary significantly from period to period. Net
realized investment gains before taxes were $10.3 million in the first six
months of 2001 compared with net gains of $11.9 million for the same period in
2000.

CAPITAL RESOURCES

       In July 1998, the Board of Directors authorized the purchase of up to
12,500,000 shares of the Corporation's common stock. In June 2001, the Board of

3,889,800 shares in open-market transactions at a cost of $280.6 million. As of
June 30, 2001, 3,287,100 shares remained under the 1998 share purchase
authorization and 14,448,100 shares remained under the 2001 authorization.

       The Corporation's $200 million short term revolving credit facility,

There have been no borrowings under this agreement.
