Expected maturities of mortgage-backed securities may differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

As of December 31, 2011, the Company held 317 investment securities of which 10 were in a loss position for less than twelve months. No securities were in a loss position for twelve months or more. Management periodically evaluates each investment security for other-than-temporary impairment relying primarily on industry analyst reports and observations of market conditions and interest rate fluctuations. Management believes it will be able to collect all amounts due according to the contractual terms of the underlying investment securities.

Securities of Government Agency and Government Sponsored Entities

The unrealized losses on the Company's investments in securities of government agency and government sponsored entities were caused by interest rate increases. Repayment of these investments is guaranteed by an agency of the U.S. government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company's investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2011.

Mortgage Backed Securities

The unrealized losses on the Company's investment in mortgage backed securities were caused by interest rate increases. The contractual cash flows of these investments are guaranteed by an agency or government sponsored entity of the U.S. government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company's investment. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not have to sell the securities before recovery of their cost basis, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2011.

Obligations of States and Political Subdivisions

The continuing financial problems being experienced by certain municipalities, along with the financial stresses exhibited by some of the large monoline bond insurers have increased the overall risk associated with bank-qualified municipal bonds. As of December 31, 2011, over ninety-two percent of the Company's bank-qualified municipal bond portfolio is rated at either the issue or issuer level, and all of these ratings are “investment grade.” The Company monitors the status of the eight percent of the portfolio that is not rated and at the current time does not believe any of them to be exhibiting financial problems that could result in a loss in any individual security.

The unrealized losses on the Company's investment in obligation of states and political subdivision were $0 at December 31, 2011 and $241,000 at December 31, 2010. Management believes that any unrealized losses on the Company's investments in obligations of states and political subdivisions were caused by interest rate increases. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because the Company did not intend to sell the securities and it was more likely than not that the Company would not have to sell the securities before recovery of their cost basis, the Company did not consider these investments to be other-than-temporarily impaired at December 31, 2011.
