                   Notes to Consolidated Financial Statements
                               September 30, 2001
                                   (Unaudited)

        The accompanying interim consolidated financial statements should be
read in conjunction with the following notes and with the Consolidated Financial
Statements included in the Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 2000.

1.      FEDERAL AND FOREIGN INCOME TAXES

        The federal and foreign income tax provision has been computed based on
the Company's estimated annual effective tax rate which differs from the federal
income tax rate of 35% principally because of tax-exempt investment income.

2.      PER SHARE DATA

        Basic per share data is based upon the weighted average number of shares
outstanding during the year. Shares issued in connection with loans to
shareholders are not considered to be outstanding for the purpose of calculating
basic per share amounts unless and until the loan is fully satisfied. The
related amounts due from shareholders are excluded from stockholders' equity.
Diluted per share data reflects the dilution that would occur if dilutive
employee stock options were exercised. On March 6, 2001 the Company issued
3,105,000 shares of its common stock in a public offering. The Company received
net proceeds of $121 million from such offering.

3.      REINSURANCE CEDED

        The amounts of reinsurance ceded included in the statements of
operations are as follows (amounts in thousands):

Ceded losses and loss expenses                               $101,618        $76,458       $232,108         $178,253

        Ceded premiums earned were $258 million in the first nine months of 2001
and included ceded earned premiums of $31 million under the aggregate
reinsurance agreement described below. In 2001, the Company implemented a series
of changes to its ceded reinsurance program. These changes included increasing
the catastrophe reinsurance protection for weather-related losses to a maximum
of $48.5 million (from $34 million in 2000) above our retention of $6 million,
increasing retention levels for individual property casualty risks (generally to
$1 million in 2001 from $300,000 to $500,000 in 2000) and replacing various
individual reinsurance contracts with a multi-year aggregate reinsurance
agreement. The aggregate reinsurance agreement provides protection for
individual losses on an excess of loss or quota share basis, as specified for
each class of business covered by the agreement, and also provides protection
for our reinsurance segment for loss and loss adjustment expenses incurred above
a certain level beginning for the 2001 accident year. Coverage begins as the
various predecessor treaties expire through April 1, 2002 and is subject to
annual limits and an aggregate limit over the contract period.

5.      INDUSTRY SEGMENTS


        In the third quarter of 2001, the Company announced its plans to
discontinue its personal lines business and the alternative markets division of
its reinsurance segment. These discontinued businesses are now being managed and
reported collectively as a separate business segment ("inactive business").
Segment information for the prior period has been restated to reflect these
changes.

        The Company's operations are now conducted through six segments of the
property casualty insurance business: specialty lines of insurance (including
excess and surplus lines and commercial transportation); alternative markets
(including the management of alternative insurance market mechanisms);
reinsurance; regional property casualty insurance; international; and inactive
business. The specialty segment's business is principally within the excess and
surplus lines, professional liability, commercial transportation and surety
markets. The Company's alternative markets segment specializes in developing,
insuring and administering self-insurance programs and various alternative risk
transfer mechanisms for employers, employer groups, insurers and alternative
markets funds. The Company's reinsurance segment specializes in underwriting
property, casualty and surety reinsurance on both a treaty and facultative
basis. The regional property casualty insurance segment principally provides
commercial property casualty insurance products. The international segment
writes property and casualty insurance, as well as life insurance, and has
business in Argentina and the Philippines. For the nine months ended September
30, 2001 and 2000, the international segment wrote life insurance premiums of
$23.6 million and $24.7 million, respectively.


        The accounting policies of the segments are the same as those described
in the summary of significant accounting policies in the Company's Annual Report
on Form 10-K for the fiscal year ended December 31, 2000. Income tax expense
(benefits) are calculated in accordance with the Company's tax sharing
agreements, which provide for the recognition of tax loss carry-forwards only to
the extent of taxes previously paid. Summary financial information about the
Company's operating segments is presented in the following table. Income (loss)
before income taxes by segment consists of revenues less expenses related to the
respective segment's operations. These amounts include realized gains (losses)
where applicable. Intersegment revenues consist primarily of dividends and
interest on inter-company debt. Identifiable assets by segment are those assets
used in the operation of each segment.

                   W. R. Berkley Corporation and Subsidiaries
              Notes to Consolidated Financial Statements, Continued

6.      OTHER MATTERS

        Reclassifications have been made in the 2000 financial statements as
originally reported to conform them to the presentation of the 2001 financial
statements.

        In the opinion of management, the summarized financial information
reflects all adjustments (consisting of normal recurring accrual or adjustments)
which are necessary for a fair presentation of financial position and results of
operations for the interim periods. The consolidated results of operations for
the interim periods are not necessarily indicative of the results to be
anticipated for the entire year. Seasonal weather variations and other
catastrophes affect the severity and frequency of losses sustained by the
insurance and reinsurance subsidiaries. Although the effect on the Company's
business of such natural and man made catastrophes as tornadoes, hurricanes,
hailstorms, earthquakes and terrorist acts is mitigated by reinsurance, they
nevertheless can have a significant impact on the results of any one or more
reporting periods.

7.      RECENT ACCOUNTING PRONOUNCEMENTS

        In the first quarter 2001 the Company adopted FAS 133, "Accounting for
Derivative Instruments and Hedging Activities," which establishes accounting and
reporting standards for derivative instruments. The adoption of this statement
did not have a material impact on the Company's results of operations or
financial condition.

        In July 2001, the FASB issued Statement No. 141, "Business
Combinations", and Statement No. 142, "Goodwill and Other Intangible Assets".
Statement 141 requires that the purchase method of accounting be used for all
business combinations initiated after June 30, 2001 as well as all purchase
method business combinations completed after June 30, 2001. Statement 142 will
require that goodwill and intangible assets with indefinite useful lives no
longer be amortized, but instead tested for impairment at least annually in
accordance with the provisions of Statement 142. Amortization of goodwill was
$3,031,000 and $2,932,000 for the nine months ended September 30, 2001 and 2000,
respectively. Statement 142 is effective in fiscal years beginning after
December 15, 2001. The Company has not yet determined the impact of Statement
142 to its consolidated financial statements.

        In August 2001, the FASB issued Statement No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets". This Statement addresses financial
accounting and reporting for the impairment or disposal of long-lived assets.
The provisions of this Statement are effective for financial statements issued
for fiscal years beginning after December 15, 2001. The adoption of this
Statement will not have a material impact on the Company's results of operations
or financial condition.

8.      SUBSEQUENT EVENT

        On November 6, 2001 the Company issued 3,795,000 shares of its common
stock in a public offering and received net proceeds of $194.4 million. Proceeds
of the offering will be used to provide additional capital for the Company's
insurance subsidiaries and for general corporate purposes.

within the meaning of the Private Securities Litigation Reform Act of 1995. Any
forward-looking statements contained herein, including those related to the
Company's performance for the year 2001 and beyond, are based upon the Company's
historical performance and on current plans, estimates and expectations. They
are subject to various risks and uncertainties, including but not limited to,
the cyclical nature of the property casualty industry, the long-tail and
potential volatile nature of the reinsurance business, product demand and

uncertain nature of damage theories and loss amounts and the development of
additional facts related to the attacks of September 11, 2001, the increased
level of our retention, natural and man-made catastrophic losses, including as a
result of terrorist activities, the impact of competition, availability of
reinsurance, the ability of our reinsurers to pay reinsurance recoverables owed
to us, investment results, exchange rate and political risks, legislative and
regulatory developments, changes in the ratings assigned to us by rating
agencies, the effects of the refocusing of our business, including our
withdrawal from the personal lines business, uncertainty as to reinsurance
coverage for terrorist acts, availability of dividends from our insurance
company subsidiaries, our successful integration of acquired companies or
investment in new insurance ventures, our ability to attract and retain
qualified employees and other risks detailed from time to time in the Company's
filings with the Securities and Exchange Commission. These risks could cause the
Company's actual results for the year 2001 and beyond to differ materially from
those expressed in any forward-looking statement made by or on behalf of the
Company. Forward-looking statements speak only as of the date on which they are
made.

         of Operations

Operating Results for the First Nine Months of 2001 as Compared to the First
Nine Months of 2000

        The Company reported a net loss of $27 million, or 97 cents per diluted
share, in the first nine months of 2001, compared with net income of $18
million, or 70 cents per diluted share, in the earlier-year period. Following
are the components of net income (loss) for the nine months ended September 30,

        In the third quarter of 2001, the Company prepared a plan to
discontinue its personal lines business and the alternative markets division of
its reinsurance segment. The Company is withdrawing from the personal lines
business, both homeowners and private passenger automobile, by not renewing
existing policies and ceasing to write new personal lines business. The
after-tax loss related to the discontinued businesses was $51 million, or $1.78
per diluted share, for the first nine months of 2001. The Company also expects
to incur an after-tax charge of approximately $2 million for severance and
related costs in the fourth quarter of 2001.

        Underwriting - Gross and net premiums written increased by 19.6% and
21.9%, respectively, in the first nine months of 2001, compared with the
earlier-year period. Following is a summary of gross and net premiums written by
business segment for the nine months ended September 30, 2001 and 2000 (amounts

        The increase in gross premiums written reflects higher prices and an
increase in new business. Gross premiums written for the reinsurance segment
also reflect a planned reduction in pro rata treaty business. Ceded premiums
written, expressed as a percentage of gross premiums written, decreased to 16.1%
from 17.7% in the prior year. The decrease reflects higher net retentions for
the specialty segment, which was partially offset by additional premiums ceded
by the reinsurance segment under the aggregate reinsurance agreement (see Note 3
of "Notes to Consolidated Financial Statements").

        Underwriting results represent net premiums earned less net loss and
loss adjustment expenses incurred and underwriting expenses incurred.
Underwriting losses increased to $165 million in the nine months ended September
30, 2001 compared with $97 million in the earlier-year period. The increase in
underwriting losses reflects higher underwriting losses for the inactive
business segment and higher catastrophe losses. Underwriting losses for the
inactive business segment increased to $85 million in 2001 from $17 million in
2000 as a result of prior year loss development for the alternative markets
reinsurance division. Catastrophe losses were $92 million in 2001 compared with
$43 million in 2000. Catastrophe losses related to the September 11, 2001 events
were $35 million, including $26 million for the reinsurance segment and $9
million for the specialty segment. This represents our maximum retention for
property and business interruption coverages and our estimated policy limits on
risks exposed to casualty losses. These estimates are based on our analysis to
date and our examination of known exposures and may need to be increased as more
information becomes available. Ceded losses and loss expenses were $232 million
in the first nine months 2001 and included loss recoveries of $42 million under
the aggregate reinsurance agreement. Following is a summary of earned premiums
and combined ratios (losses, loss expenses and underwriting expenses expressed
as a percentage of premiums earned) by business segment for the nine months
ended September 30, 2001 and 2000 (amounts in thousands).

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


        The decrease in the specialty combined ratio reflects the impact of
pricing actions and other underwriting initiatives, which were offset by losses
related to the September 11, 2001 events. The decrease in the alternative
markets combined ratio reflects a lower expense ratio as a result of higher
premium volume. The increase in the reinsurance combined ratio reflects losses
related to the September 11, 2001 events and unfavorable prior year loss
development, which were offset by loss recoveries under the aggregate
reinsurance agreement. The decrease in the regional combined ratio reflects the
impact of pricing actions and other underwriting initiatives. The decrease in
the international combined ratio reflects lower losses and expenses for
automobile business in Argentina.

        Insurance Services - Insurance services income represents service fees
less related costs and expenses for the insurance services business. Insurance
service fees increased 17% to $55 million as a result of new accounts and higher
revenues on existing accounts, and insurance services income increased 21% to $6
million.

        Investments - The decrease in net investment income of 4% reflects a
decrease in the yield on the merger arbitrage account to 4.9% in 2001 from 10.5%
in 2000. This was somewhat offset by a higher yield on the fixed income
portfolio as a result of changes in asset allocations and an increase in average
invested assets.

        Other Items - Interest and other represents interest expense, corporate
expenses, and other miscellaneous income and expenses. The restructuring charge
in 2000 related to the reorganization of the reinsurance operations. Realized
investment gains and losses result from security sales and from changes in
provisions for other than temporary impairment of securities. The effective
income tax rate differs from the federal income tax rate of 35% principally
because of tax-exempt investment income.

Operating Results for the Third Quarter of 2001 as Compared to the Third Quarter
of 2000

        Net loss was $47 million, or $1.63 cents per diluted share, for the
third quarter of 2001 compared with net income of $7 million, or 27 cents per
diluted share, for the corresponding 2000 period. Following are the components
of net income for the third quarters of 2001 and 2000 (amounts in thousands).

        Gross and net premiums increased by 23.5% and 24.8%, respectively,
reflecting price increases and changes in reinsurance costs as discussed above.
Underwriting losses increased by $74 million and the combined ratio deteriorated
to 126.7% from 110.6% in the earlier-year period, generally for the reasons
discussed above. Net investment income decreased by 17%, generally for the
reasons discussed above.

Liquidity and Capital Resources

        Cash flow from operating activities (before trading account purchases)
increased to $129 million for the first nine months of 2001 from $79 million for
the same period in 2000. The increase in cash flow reflects higher collected
premiums, which more than offset an increase in paid losses. The cost basis of
the investment portfolio (including account receivable from brokers and clearing
organizations and securities sold but not yet purchased) was $3,350 million at
September 30, 2001 compared with $3,074 million at December 31, 2000. The
increase reflects cash flow from operations and the proceeds from the common
stock public offering completed in the first quarter of 2001.

        At September 30, 2001, as compared with December 31, 2000, the fixed
maturity investment portfolio was as follows: U.S. Government and cash
equivalent were 33.1% (31.1% in 2000); state and municipal securities were 19.5%
(23.7% in 2000); mortgage-backed securities were 22.5% (21.8% in 2000);
corporate securities were 19.7% (18.0% in 2000) and foreign bonds were 5.2%
(5.4% in 2000).

        The Company's equity portfolio is comprised of merger arbitrage
securities, which are classified as trading account assets, and other equity
investments, which are classified as available for sale. Net trading account
assets (trading account equity securities plus trading account receivable from
brokers and clearing organizations less trading account equity securities sold
but not yet purchased) were $460 million as of September 30, 2001 compared with
$448 million as of December 31, 2000.

        On March 6, 2001, the Company issued 3,105,000 shares of its common
stock in a public offering and received net proceeds of $121 million. In March
2001, the Company repaid $10 million short-term debt that was outstanding since
December 31, 2000.

        For the first nine months of 2001, stockholders' equity increased by
approximately $129 million to $810 million as a result of the common stock
public offering of $121 million and comprehensive income of $11 million. At
September 30, 2001 the Company's total capitalization was $1,378 million and the
percentage of the Company's capital attributable to long-term debt was 27%,
compared with 30% at December 31, 2000.

        On November 6, 2001, the Company issued 3,795,000 shares of its common
stock in a public offering and received net proceeds of $194.4 million. Proceeds
of the offering will be used to provide additional capital for the Company's
insurance subsidiaries and for general corporate purposes.

Liquidity and Capital Resources, see the Company's Annual Report on Form 10-K
for the fiscal year ended December 31, 2000.

Item 3.  Quantitative and Qualitative Disclosure About Market Risk

        The Company's market risk generally represents the risk of gain or loss
that may result from the potential change in the fair value of the Company's
investment portfolio as a result of fluctuations in prices, interest rates and
currency exchange rates.

        The cost of the Company's investments in Argentine bonds and bank
deposits was $129 million at September 30, 2001. The Company seeks to mitigate
foreign currency exchange rate risk associated with these investments by
maintaining its capital in US dollar denominated securities. Investments in
Argentine bonds and bank deposits, including those denominated in US dollars,
are subject to risks of changes in general political and economic conditions in
Argentina and to possible impairment in value as a result of further
deterioration in credit quality of such investments.

        The Company attempts to manage its interest rate risk by maintaining an
appropriate relationship between the average duration of the investment
portfolio and the approximate duration of its liabilities, i.e., policy claims
and debt obligations. The Company has maintained approximately the same duration
of its investment portfolio to its liabilities from December 31, 2000 to
September 30, 2001, and the overall market risk relating to the Company's
portfolio has remained similar to the risk at December 31, 2000.
