Third quarter highlights included:

• Premiums written increased 14% on a net basis and 16% on a gross basis.

• Average premium rates increased 3%.

• GAAP combined ratio was 99.1% including catastrophe losses and 94.3% excluding catastrophe losses.

• The Company repurchased 4 million shares of common stock at an average cost of $29.70 per share and an aggregate cost of $118 million.

     Commenting on the Company’s performance, William R. Berkley, chairman and chief executive officer, said: “We are pleased with our third quarter results, especially given the level of catastrophe activity, the difficult economic environment and historically low interest rates. Our net written premiums increased by more than 14% in the quarter as our operating units found opportunities to grow profitably. The visibility of a cycle change is even more evident, with prices for the quarter up three percent over last year. We believe that price increases and premium volume growth will continue.

     “Our investment results continue to be more than satisfactory. The yield on our fixed income portfolio is approximately the same as it was a year ago. While we anticipate more volatility in the balance of the portfolio from quarter to quarter, we do not expect our investment returns over a longer period of time to vary significantly from historical levels.

     “While some industry observers suggest that excess capital is a major restraint on pricing levels, history does not support their perception. Capital has never been the primary driver of cyclical change in the business; it has merely added impetus or restraint. Given the current interest rate environment, the industry needs significant price increases in nearly all lines of business in order to achieve even minimally adequate returns.

     “We are confident that our results will benefit from the improving market conditions as well as our focus on optimizing risk adjusted returns and increasing book value for our shareholders,” Mr. Berkley concluded.

(1)	Operating income is a non-GAAP financial measure defined by the Company as net income excluding net investment gains and losses. Management believes that excluding net investment gains and losses, which are often discretionary and frequently relate to economic factors, provides a useful indicator of trends in the Company’s underlying operations.
	In 2011, the Company modified its definition of operating income to include income and losses from investment funds, which had previously been excluded. Operating income for prior periods has been modified to conform to this definition. For the third quarters of 2011 and 2010, losses from investment funds were $8 million and $19 million, respectively. For the first nine months of 2011 and 2010, income (losses) from investment funds was $24 million and ($13 million), respectively.
(2)	Return on equity represents net income expressed on an annualized basis as a percentage of beginning of year stockholders’ equity.
