prior year periods:

     o    Gross premiums written for continuing business grew 56% in the fourth
          quarter to $885 million.

     o    GAAP combined ratio for continuing business was 93.3% in the fourth
          quarter compared with a combined ratio of 112.4% in the prior year
          quarter.

     o    The paid loss ratio for continuing business decreased to 43.5% in the
          fourth quarter from 61.0% in the prior year quarter, and the
          paid-to-incurred loss ratio decreased to 67.8% in 2002 from 76.8% in
          2001.

     o    Cash flow from operations increased to $223 million in the fourth
          quarter compared with $81 million in the prior year quarter. For the
          full year, cash flow from operations increased to $766 million from
          $210 million in 2001.

     Commenting on the Company's results, William R. Berkley, chairman and chief
executive officer, said: "Our excellent results continue to reflect strategic
decisions made over the past several years to consolidate our operations and
focus on our most profitable lines of business. This focus also resulted in the
early recognition of past reserve deficiencies, and thus, we are able to reflect
in our current results the benefits of higher prices and improved terms and
conditions.

     "We are continuing our cautious reserving practices to guard against the
possibility of future adverse reserve development. We believe our current
financial statements reflect a prudent view in an uncertain world. The earned
premiums reported on our 2002 financial statements only partially reflect the
increased pricing that was in effect in 2002. If in fact year-end price levels
had been in effect for the full year and earned in that year, our 2002 results
would have been substantially better than those reported. As a result, we expect
significantly better results in 2003.

     "This year, even with lower investment returns, we achieved a return on
beginning capital of over 18%, and a return of 17% on an operating basis. We
look ahead with continued enthusiasm and believe overall industry problems will
result in a continuation of the current pricing environment of increasing rates
at least through 2004," Mr. Berkley concluded.

     Founded in 1967, W. R. Berkley Corporation is an insurance holding company

     cents per share after-tax.

(3)  Foreign currency gains represent net gains reported by the company's foreign subsidiaries
     and result primarily from translating into Argentine pesos, invested assets and life
     insurance liabilities denominated in US dollars, and of settling certain life insurance
     contracts for less than their stated value following the devaluation of the Argentine peso.
     The company also reported an unrealized foreign exchange loss of $15.2 million (net of
     minority interest) as a result of the translation of the net assets of its Argentine
     subsidiary to US dollars. Under generally accepted accounting principles, unrealized
     foreign exchange losses are reported directly to stockholders' equity.

(4)  The 2001 results for the discontinued business reflect loss reserve increases of $52.5
     million pre-tax, or 72 cents per share after-tax, in the fourth quarter and $102.5 million
     pre-tax, or $1.52 per share after-tax, for the full year. The 2001 results for the
     discontinued business also include a fourth quarter restructuring charge of $2.1 million
     after-tax, or 4 cents per share.

(1)  Full year 2001 pre-tax operating income for the specialty segment reflects World Trade
     Center losses of $9.0 million.

(2)  In the fourth quarter of 2002, the company changed its presentation of reinsurance premiums
     assumed from Lloyd's syndicates to reflect the company's proportionate share of the
     syndicates' reinsurance costs as ceded premiums and its share of the syndicates' brokerage
     cost as underwriting expenses. Previously, this business was presented similar to the
     manner it is reported by the syndicates, with reinsurance and brokerage costs netted
     against premiums. Amounts reported in prior quarters of 2002 were reclassified to reflect
     this change. The change had no effect on underwriting profits or net income for the current
     or prior quarters.

     Fourth quarter 2001 pre-tax operating income for the reinsurance segment reflects an
     increase in reinsurance reserves of $32.8 million and losses related to the Enron

     segment also reflects World Trade Center losses of $26.0 million.

     increases of $52.5 million in the fourth quarter and $102.5 million for full year.
