The Company's expense ratio was 32.6% for the second quarter of 2010, compared to 31.0% for the second quarter of 2009, with the increase attributable to increased acquisition costs related to current period premium growth.

Net investment income was $4,968,490 for the second quarter of 2010, compared to $5,266,161 for the second quarter of 2009. The impact of lower market interest rates during the second quarter of 2010 offset investment income attributable to an increase in average invested assets compared to the year earlier period. The Company had no other-than-temporary impairments in its investment portfolio. Net realized investment gains from the sale of securities were $1,965,091 for the second quarter of 2010, compared to $445,140 for the year-earlier period.
