There were no held-to-maturity investment securities with unrealized losses as of September 30, 2011 or December 31, 2010.

At September 30, 2011, the Company held 169 securities of which 9 were in a loss position for less than twelve months and none were in a loss position for twelve months or more. Of the 9 securities in a loss position, 6 are mortgage-backed securities and 3 are obligations of states and political subdivisions. At December 31, 2010, the Company held 168 securities of which 29 were in a loss position for less than twelve months and 5 were in a loss position for twelve months or more. Of the 34 securities in a loss position, 15 were mortgage-backed securities, 11 were obligations of states and political subdivisions and 8 were corporate stocks.

The unrealized loss on the Company’s investments in mortgage-backed securities and obligations of states and political subdivisions at September 30, 2011 is primarily driven by interest rates. Because the decline in market value is attributable to a change in interest rates and not credit quality, and because the Company has the ability and intent to hold these investments until recovery of fair value, which may be until maturity, management does not consider these investments to be other-than-temporarily impaired.

The amortized cost and estimated fair value of investment securities at September 30, 2011 by contractual maturity are shown below (dollars in thousands).
