Note 11 - Investment in Securities

Investment securities available-for-sale are recorded at fair value on a recurring basis. The Company's investment securities available-for-sale are measured at fair value using Level 2 valuations. The market evaluation utilizes several sources which include "observable inputs" rather than "significant unobservable inputs" and therefore fall into the Level 2 category. The amortized cost, gross unrealized gains, gross unrealized losses and fair value of investment securities are summarized as follows:

The fair values of securities with unrealized losses are as follows:

There were 66 securities, or 21% of the total (none greater than 12 months), in an unrealized loss position as of September 30, 2013. There were 18 securities, or 5% of the total (none greater than 12 months), in an unrealized loss position as of December 31, 2012. All unrealized losses were reviewed to determine whether the losses were other than temporary. Management believes that all unrealized losses are temporary since they were market driven, and the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery.

The amortized cost and fair value of investment securities by contractual maturity are shown in the following table. Expected maturities may differ from contractual maturities because borrowers have the right to prepay obligations with or without prepayment penalties.

    September 30, 2013
(In thousands)       Amortized Cost       Fair Value
Due in 1 year or less   $ 12,838   $ 12,961

Due after 5 years through 10 years     139,442     141,773
