Highlights for the second quarter and year-to-date include: * Net income for the second quarter of 2006 of $8.6 million compared to net income of $4.7 million for the second quarter of 2005 ($15.4 million for the six months ended June 30, 2006 compared to $9.3 million for the same period in 2005); * Overall combined ratio of 82.9% for the second quarter (84.3% year-to-date); * Underwriting profit grew 59.8% for the second quarter of 2006 (from $5.6 million in 2005 to $9.0 million in 2006) and 39.3% for the six month period (from $11.4 million in 2005 to $15.9 million in 2006); * 29.1% growth in gross written premiums to $74.6 million in the second quarter of 2006 from $57.8 million in the second quarter of 2005 (on a year-to-date basis, a 36.2% increase to $142.8 million from $104.8 million); * Annualized return on average stockholders' equity of 18.6% for the second quarter and 17.0% on a year-to-date basis through June 30, 2006; and * Favorable development on prior years' reserves for direct business during the second quarter of $1.3 million after tax ($2.8 million after-tax on a year-to-date basis). Earnings per diluted share for the second quarter of 2006 were $0.53 compared to earnings per diluted share of $0.46 for the second quarter of 2005. Earnings per diluted share for the first six months of 2006 were $0.96 compared to earnings per diluted share of $0.91 for the same period in 2005. Weighted-average diluted shares outstanding for the second quarter of 2006 were 16.0 million (15.9 million on a year-to-date basis) compared to 10.2 million for both the first six months and the second quarter of 2005. Weighted-average diluted shares outstanding for 2006 exceeded the weighted-average diluted shares outstanding for the prior year principally as a result of shares issued in the Company's initial public offering in August 2005. For the quarter ended June 30, 2006, the Excess and Surplus Insurance segment wrote $63.8 million in gross written premiums reflecting a 29.0% increase over the $49.5 million in gross written premiums written in the same period in 2005. For the six months ended June 30, 2006, this segment wrote $121.6 million in gross written premiums reflecting a 33.2% increase over the $91.2 million in gross written premiums written in the same period in 2005. The Excess and Surplus Insurance segment's combined ratio was 77.5% and 78.4% for the quarter and six months ended June 30, 2006, respectively. The Workers' Compensation Insurance segment wrote $10.8 million in gross written premiums in the quarter ended June 30, 2006 for a 30.2% increase over the prior year's $8.3 million in gross written premiums. For the six months ended June 30, 2006, this segment wrote $21.2 million in gross written premiums for a 56.4% increase over the prior year's $13.6 million in gross written premiums. The Workers' Compensation Insurance segment's combined ratio was 95.6% for the quarter and was 101.3% on a year-to-date basis. The year-to-date underwriting loss for the Workers' Compensation Insurance segment of $0.2 million was driven by $0.8 million, or 4.4 points on the combined ratio, in costs allocated from the North Carolina involuntary workers' compensation pool's operating results. J. Adam Abram, President and Chief Executive Officer, said, "We are pleased with our results for the quarter. Each of our subsidiaries grew substantially and earned solid underwriting profits. 2006 promises to be a very good year; we anticipate achieving an annual return on average equity of at least 15% and writing at a combined ratio of between 80% and 90%. We also expect growth in gross written premiums of between 20% and 30% for 2006."

Reconciliation of Non-GAAP Measure The following table reconciles the underwriting profit (loss) by individual segment and of the whole company to consolidated income before taxes. We believe that these measures are useful to investors in evaluating the performance of our Company and its insurance segments because our objective is to consistently earn underwriting profits. We evaluate the performance of our insurance segments and allocate resources based primarily on underwriting profit (loss) of insurance segments. Our definition of underwriting profit (loss) of insurance segments and underwriting profit (loss) may not be comparable to the definition of underwriting profit (loss) for other companies.
