BERKLEY CORPORATION ISSUES STATEMENT ON WORLD TRADE CENTER TRAGEDY Company Estimates Potential Pre-Tax Losses GREENWICH, CT., September 14, 2001 - W. R. Berkley Corporation (NYSE: BER) Chairman William R. Berkley issued the following statement today, "The events of the past several days have created much sadness in America as well as a sense of deep personal concern within our organization. This has not altered our confidence in our institutions or the importance of individual freedom. We have many friends who lost their lives in this abominable terrorist act and to all the families that suffered we offer our condolences." In addressing the business issue, Mr. Berkley commented, "Although it is too early to make a precise assessment of the financial impact to the company of these events, based on our preliminary analysis and our examination of all known exposures, we do not expect our pre-tax losses to exceed $10 million. In the unlikely event all reinsurance retentions are exhausted, our company's net pre-tax losses would be less than $25 million. We do not currently believe that we have any significant liability exposures." Founded in 1967, W. R. Berkley Corporation is an insurance holding company, which operates in five segments of the property casualty insurance business: specialty insurance, alternative markets, reinsurance, regional property casualty insurance and international. ******* This is a "Safe Harbor" Statement under the Private Securities Litigation Reform Act of 1995.
