     Commenting on the Company’s performance, William R. Berkley, chairman and chief executive officer, said: “We are very pleased with the fourth quarter and full year results. The business continued its robust performance, generating an after-tax return on equity of over 27% for the fourth quarter. Each segment of the business reported underwriting profits in 2004. At the same time, we had cash flow for the year of over $1.6 billion. As a result of the cash flow and an upturn in investment yields, investment income reached $82 million in the fourth quarter. For the year, investment income grew 39% to over $291 million.

     “We continue to be optimistic about the environment and expect relative price stability in most parts of our marketplace. There is pressure on prices in some areas, but the overall business continues to look excellent. We expect to continue to enjoy moderate growth and we are confident that 2005 will result in after tax returns exceeding 20%,” Mr. Berkley concluded.

(1)	Net operating income is a non-GAAP financial measure defined by the Company as net income excluding realized investment gains and the effect of a change in accounting principle. Management believes that excluding realized investment gains, which result primarily from changes in general economic conditions and the effect of a change in accounting principle provides a useful indicator of trends in the Company’s underlying operations.
(2)	Return on equity represents net income expressed on an annualized basis as a percentage of beginning of year stockholders’ equity.
(3)	Cash flow from operations before cash transfers to/from trading account is a non-GAAP financial measure that excludes cash contributions to and withdrawals from the arbitrage trading account. Management believes that cash transfers to/from the arbitrage trading account are the result of changes in investment allocations and that excluding such transfers provides a useful measure of the Company’s cash flow.
(4)	Investments include cash and cash equivalents, accounts receivable from brokers and clearing organizations and securities sold but not yet purchased.
(5)	Stockholders’ equity includes after-tax unrealized gains from investments and foreign exchange of $112 million and $120 million as of December 31, 2004 and December 31, 2003, respectively.
