Fourth quarter highlights included:

• The overall return on equity was 17.6%, and the operating return on equity was 15.5%.

• Book value per share increased to $22.97.

• Investment income increased 24%.

• GAAP combined ratio was 92.6%.

• Cash flow from operations was $151 million.

• Repurchased 4.6 million shares of common stock for $112 million.

     The Company also announced that its Board of Directors has increased the Company’s share repurchase authorization by 10 million shares, to 11.5 million shares. The increased authorization represents approximately 7 percent of the Company’s shares outstanding at December 31, 2009. Repurchases may be made from time to time at prevailing prices in the open market or in privately negotiated transactions, subject to market conditions and other factors.

     Commenting on the Company’s performance, William R. Berkley, chairman and chief executive officer, said: “We are pleased with our results for the quarter. Underwriting performance was in line with our expectations and investment returns are approaching their historic levels. Operating return on equity of 15.5 percent reached our target even as we continued to invest in new operating units that will better position us for the future.

     “As we maintain disciplined pricing, our existing book of business continues to modestly shrink. It is still hard to find new business that is attractively priced in the current marketplace. However, we are beginning to see improving price trends in selected lines of business.

     “Our investment portfolio continues to perform well with the fixed income portion having an average rating of AA and a duration that is slightly shorter than the duration of our liabilities. We feel comfortable with our existing investment portfolio and remain optimistic about its longer term performance.

     “In the fourth quarter, the company repurchased 4.6 million shares of its common stock, and in January of 2010 we repurchased another 3.8 million shares. As our earnings generate capital in excess of what our business requires, we will evaluate how to use the excess in our already well-capitalized business. We see signs of a cyclical change and are particularly well-positioned for a market turn. We are expecting to achieve our goal of a 15% return on equity for the year and continue to be positive on the opportunities for our company,” Mr. Berkley concluded.

(1)	Operating income is a non-GAAP financial measure defined by the Company as net income excluding income or losses from investment funds and net investment gains and losses. The Company refined its definition of operating income beginning with the second quarter of 2009. Management believes that excluding income and losses from investment funds and net investment gains and losses, which result primarily from changes in general economic conditions, provides a useful indicator of trends in the Company’s underlying operations.
(2)	Return on equity represents net income and net operating 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 and withdrawals 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.
