Peoples’ investment in equity securities was comprised entirely of common stocks issued by various unrelated bank holding companies at both December 31, 2012 and December 31, 2011. At December 31, 2012, there were no securities of a single issuer, other than U.S. Treasury and government agencies and U.S. government sponsored agencies, that exceeded 10% of stockholders' equity.

The gross gains and gross losses realized by Peoples from sales of available-for-sale securities for the years ended December 31 were as follows:

Management systematically evaluates available-for-sale investment securities for other-than-temporary declines in fair value on a quarterly basis. At December 31, 2012, management concluded no individual securities were other-than-temporarily impaired since Peoples did not have the intent to sell nor was it more likely than not that Peoples would be required to sell any of the securities with an unrealized loss prior to recovery. Further, the unrealized losses at both December 31, 2012 and December 31, 2011, were largely attributable to changes in market interest rates and spreads since the securities were purchased.

At December 31, 2012, approximately 96% of the mortgage-backed securities that have been at an unrealized loss position for twelve months or more were issued by U.S. government sponsored enterprises. The remaining 4%, or seven positions, consisted of privately issued mortgage-backed securities with all of the underlying mortgages originated prior to 2004. Three of the seven positions had a fair value less than 90% of their book value, with an aggregate book and fair value of $2.0 million and $1.6 million, respectively. Management has analyzed the underlying credit quality of these securities and concluded the unrealized losses were primarily attributable to the floating rate nature of these investments and the low number of loans remaining in these securities.

Furthermore, two of the five bank-issued trust preferred securities which were in an unrealized loss position were within 90% of book value, while the unrealized losses for the remaining three were primarily attributable to the floating nature of those investments, the current interest rate environment and spreads within that sector. The remaining three securities had an aggregate book value of approximately $3.0 million and fair value of $2.4 million at December 31, 2012.

The table below presents the amortized cost, fair value and weighted-average yield of available-for-sale securities by contractual maturity at December 31, 2012. The average yields are based on the amortized cost. In some cases, the issuers may have the right to call or prepay obligations without call or prepayment penalties prior to the contractual maturity date. Rates are calculated on a fully tax-equivalent basis using a 35% federal income tax rate.
