At December 31, 2014, all eleven available-for-sale securities had unrealized losses with an aggregate depreciation of 1.3% from the amortized cost. At December 31, 2013, all eleven securities had unrealized losses with an aggregate depreciation of 3.2% from the amortized cost. The Company performs a quarterly analysis of those securities that are in an unrealized loss position to determine if those losses qualify as other-than-temporary impairments. This analysis considers the following criteria in its determination: the ability of the issuer to meet its obligations when the loss position is due to a deterioration in credit quality, management’s plans and ability to maintain its investment in the security, the length of time and the amount by which the security has been in a loss position, the interest rate environment, the general economic environment and prospects for improvement or deterioration. Management believes that none of the unrealized losses on available-for-sale securities noted above are other than temporary due to the fact that they relate to market interest rate changes on U.S. Government agency debt, corporate debt and mortgage-backed securities issued by U.S. Government agencies. Management considers the issuers of the securities to be financially sound, the corporate bonds are investment grade and the Company expects to receive all contractual principal and interest related to these investments. Because 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 of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2014. At December 31, 2014 and 2013, available-for-sale securities with a carrying value of $4.4 million and $5.8 million, respectively, were pledged to secure municipal deposits. The amortized cost and fair value of available-for-sale debt securities at December 31, 2014 by contractual maturity are presented below. Actual maturities of mortgage-backed securities may differ from contractual maturities because the mortgages underlying the securities may be repaid without any penalties. Because mortgage-backed securities are not due at a single maturity date, they are not included in the maturity categories in the following maturity summary.
