(a) Other-Than-Temporary Impaired Debt Securities: At June 30, 2011 and December 31, 2010, there were 37 and 52 investment securities in unrealized loss positions, respectively.  For each security in an unrealized loss position, the Company assesses whether it intends to sell the security, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. For debt securities that are considered other-than-temporarily impaired and that the Company does not intend to sell and will not be required to sell prior to recovery of its amortized cost basis, the Company will separate the amount of the impairment into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is calculated as the difference between the security's amortized cost basis and the present value of its expected future cash flows. The remaining difference between the security's fair value and the present value of future expected cash flows is deemed to be due to factors that are not credit related and is recognized in other comprehensive income.

The Company does not intend to sell the securities that are temporarily impaired, and it is more likely than not that the Company will not have to sell those securities before recovery of the cost basis. Additionally, the Company has evaluated the credit ratings of its investment securities and their issuers and/or insurers, as applicable. Based on the Company's evaluation, management has determined that no investment security in the Company's investment portfolio was other-than-temporarily impaired at June 30, 2011 or December 31, 2010.

The following table shows gross unrealized losses and fair value of securities with unrealized losses that are not deemed to be other-than-temporarily impaired, aggregated by category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2011 and December 31, 2010:

The unrealized losses associated with U.S. government agency and treasury debt securities are primarily driven by changes in interest rates and not due to the credit quality of the securities. Further, the pass-through securities backed by GNMA, FNMA or FHLMC have the guarantee of the full faith and credit of the U.S. Federal Government. Obligations of U.S. states and political subdivisions in our portfolio are all investment grade without delinquency history.

The amortized cost and fair value of investment securities, by contractual maturity at June 30, 2011, are shown in the table below.  Expected maturities may differ from contractual maturities because issuers of the securities may have the right to call or prepay obligations with or without call or prepayment penalties.
