There were 71 securities, or 24% of the total (none greater than 12 months), in an unrealized loss position as of June 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.
