Excluding the impact of hurricanes in the comparable periods, the GAAP combined ratio improved by 1.0 percentage points to 87.8%. - Hurricane losses were $50 million pre-tax, up 56% from the prior year period. - Cash flow from operations increased 32% to $613 million compared to $465 million in the year-earlier period. - Net investment income increased 50% to $108 million. - The paid loss ratio continued to be favorable at 34.2%. Commenting on the Company's performance, William R. Berkley, chairman and chief executive officer, said: "The quarter reflects the outstanding results of our operating units. We are pleased that in spite of the weather-related losses our returns are still within our forecasted range. "We continue to seek all the business available at our targeted underwriting margins. Prior to the recent hurricanes, we had anticipated that our underwriting discipline would result in modest growth. We now anticipate that these recent events will bring about greater industry focus on profitability and concomitant underwriting discipline in most lines. We are therefore more positive about growth in many of our existing businesses and see opportunities in several new areas. "Our expectation of achieving returns over twenty percent next year continues, and we believe we will be able to grow our top line. We anticipate that our company will deliver returns in excess of our fifteen percent target for the next several years," Mr. Berkley concluded. Founded in 1967, W. R. Berkley Corporation is an insurance holding company that is among the largest commercial lines writers in the United States and operates in five segments of the property casualty insurance business: specialty insurance, regional property casualty insurance, alternative markets, reinsurance and international. -2- This is a "Safe Harbor" Statement under the Private Securities Litigation Reform Act of 1995.
