All of the Company’s investment securities are classified as available for sale. Agency bonds and notes, agency mortgage-backed securities and agency collateralized mortgage obligations (CMO) include securities issued by the Government National Mortgage Association (GNMA), a U.S. government agency, and the Federal National Mortgage Association (FNMA), the Federal Home Loan Mortgage Corporation (FHLMC) and the Federal Home Loan Bank (FHLB), which are U.S. government-sponsored enterprises. Investment securities that are classified as restricted equity securities primarily consist of Federal Home Loan Bank stock and the Company’s interest in statutory trusts. These securities are reported at cost in other assets in the amount of $4.7 million and $4.0 million as of December 31, 2014 and 2013, respectively. Debt securities with carrying values aggregating approximately $145.5 million and $145.8 million at December 31, 2014 and December 31, 2013, respectively, were pledged to secure public funds, securities sold under agreements to repurchase, and for other purposes as required or permitted by law. The amortized cost and fair value of debt securities classified as available-for-sale at December 31, 2014, by contractual maturity are shown below. Expected maturities may differ from contractual maturities because borrowers have the right to call or prepay obligations with or without prepayment penalties.

The total available for sale portfolio consisted of approximately 300 securities at December 31, 2014. The portfolio included 74 securities having an aggregate fair value of $82.2 million that were in a loss position at December 31, 2014. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer totaled $65.2 million at fair value. The $1.3 million aggregate unrealized loss included in accumulated other comprehensive income at December 31, 2014 was caused by interest rate fluctuations. The total available for sale portfolio consisted of approximately 348 securities at December 31, 2013. The portfolio included 96 securities having an aggregate fair value of $115.1 million that were in a loss position at December 31, 2013. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer totaled $6.4 million at fair value. The $4.2 million aggregate unrealized loss included in accumulated other comprehensive income at December 31, 2013 was caused by interest rate fluctuations. Because the decline in fair value is attributable to changes in interest rates and not credit quality these investments were not considered other-than-temporarily impaired at December 31, 2014 and 2013, respectively. The table presents the components of investment securities gains and losses, which have been recognized in earnings:
