Full year 2007 highlights included:

• Return on equity was 22.3%.

• GAAP combined ratio was 88.1%.

• Net investment income grew 15% to $673 million.

• Paid loss ratio was 42%.

• Repurchased 15.2 million shares of the Company’s common stock, including 3.2 million shares in the fourth quarter.

     Commenting on the Company’s performance, William R. Berkley, chairman and chief executive officer, said: “We are pleased with our financial results for the fourth quarter and full year, having achieved a twenty-two percent return on equity after tax for both periods. The Company continued to have strong underwriting performance with a combined ratio of 88.1% and a paid loss ratio of 42%. While we anticipate 2008 will be increasingly competitive from an underwriting perspective, we still expect to deliver excellent returns.

     “Investment income grew by fifteen percent in 2007, without any sacrifice to the quality of the investment portfolio. We have virtually no sub-prime exposure. It is likely that investment returns will continue to be under pressure due to current economic uncertainties and the shape of the yield curve.

     “In the current environment, capital oversight is an important part of management’s responsibility. We repurchased over fifteen million shares of our common stock in 2007, representing eight percent of our outstanding shares.

     “In the long-run, every business succeeds because of its people, its relationships with its distribution and its ultimate customers. We continue to believe that we will be able to deliver outstanding returns to our shareholders and exceed our minimum targeted return of fifteen percent after tax for the foreseeable future,” Mr. Berkley concluded.
