First quarter highlights included:

• Returned $105 million to our shareholders through dividends and the repurchase of 1.8 million shares of our stock.

• Domestic net premiums written grew 6% inclusive of average rate increases of 3.2%.

• GAAP combined ratio was 93.9%.

• Net realized investment gains were $19 million.

Commenting on the Company's performance, William R. Berkley, Chairman and Chief Executive

Officer, said: "Our Company continued to perform well this quarter. We were able to increase overall rates at a level that exceeded loss cost trends, although in some areas competitive challenges became more visible. However, there are still niche opportunities within the insurance marketplace that exist for limited periods of time. Our flexible structure uniquely positions us to capitalize on them.

"We anticipate continued domestic growth and modestly improving margins for the balance of the year. Our international business improved substantially, which is more apparent if adjusted for currency effects. Our reinsurance segment is currently the most competitive part of our business. We have maintained our pricing discipline with continued profitability at a reduced volume.

"Our core investment portfolio performed well and most of our alternative investments delivered excellent returns. The most consequential impact on net income for the quarter was a loss from our energy funds, compared to a gain in the first quarter of 2014. Earnings from the energy funds declined by over $30 million year over year.

"We anticipate 2015 will be another strong year. We will maintain our capital account in line with our liabilities and premium volume. If we are unable to find opportunities to use capital within our business, we may elect to pay special dividends or repurchase our own securities. We believe we will continue to deliver outstanding returns," Mr. Berkley concluded.

Webcast Conference Call

The Company will hold its quarterly conference call with analysts and investors to discuss its earnings and other information on April 27, 2015, at 5:00 p.m. eastern time.
