We believe the unrealized losses on investment securities were attributable to market interest rate increases. The contractual terms of U.S. government and agency obligations do not permit the issuer to settle the security at a price less than the par value of the investment. The contractual cash flows of mortgage-backed securities are guaranteed by Fannie Mae, Freddie Mac and Ginnie Mae. REMICs are issued by or backed by securities issued by these governmental agencies. It is expected that the securities would not be settled at a price substantially less than the amortized cost of the investment. The U.S. Treasury Department established financing agreements in 2008 to ensure Fannie Mae and Freddie Mac meet their obligations to holders of mortgage-backed securities that they have issued or guaranteed.

Since the decline in value is attributable to changes in market interest rates and not credit quality and because the Company has neither the intent to sell the securities nor is it more likely than not the Company will be required to sell the securities for the time periods necessary to recover the amortized cost, these investments are not considered other-than-temporarily impaired.
