Adam Abram, President and Chief Executive Officer, said, "We are pleased to report these good results to our shareholders. Each of our underwriting segments continued to produce excellent results, our annualized return on average equity of 18.5% was attractive and our book value per share increased to $14.76 during the quarter even after our first quarterly dividend of $0.15 per share." Mr. Abram continued, "Our management teams found opportunities to grow each of our segments. Our Workers' Compensation Insurance segment had a great quarter with substantial premium growth and low claims costs. Our Excess and Surplus Insurance segment also grew significantly even in the face of increasing competition. We believe our low expense ratio business model is very powerful in this environment." "Looking forward to the balance of 2007," Mr. Abram added, "we anticipate our gross written premiums will increase between 10% and 20% over the prior year and that our return on average equity will be 15% or greater."
