The Company had 114 investment securities, consisting of 54 tax-exempt state and municipal obligations, 6 taxable state and municipal obligations, 32 U.S. Government-sponsored enterprise securities, 19 mortgage-backed securities, one corporate debt security, one U.S. Government agency security and one common equity security that were in unrealized loss positions at March 31, 2014. Of these securities, one U.S. Government-sponsored enterprise security and one tax-exempt state and municipal security were in a continuous unrealized loss position for twelve months or more. The unrealized loss on the common equity securities was a direct reflection of reductions from historical levels in stock values in the financial industry sector, as a whole, and was not a result of credit or other issues that would cause the Company to realize an OTTI charge. Management does not consider the unrealized losses on the debt securities, as a result of changes in interest rates, to be OTTI based on historical evidence that indicates the cost of these securities is recoverable within a reasonable period of time in relation to normal cyclical changes in the market rates of interest. Moreover, because there has been no material change in the credit quality of the issuers or other events or circumstances that may cause a significant adverse impact on the fair value of these securities, and management does not intend to sell these securities and it is unlikely that the Company will be required to sell these securities before recovery of their amortized cost basis, which may be maturity, the Company does not consider the unrealized losses to be OTTI at March 31, 2014. There was no OTTI recognized for the three months ended March 31, 2014 and 2013.

The Company had 153 investment securities, consisting of 79 tax-exempt state and municipal obligations, 16 taxable state and municipal obligations, 39 U.S. Government-sponsored enterprise securities, 15 mortgage-backed securities, one corporate debt security, one U.S. Government agency and two common equity securities that were in unrealized loss positions at December 31, 2013. Of these securities, one U.S. Government-sponsored enterprise security was in continuous unrealized loss position for twelve months or more.
