Mortgage-backed securities are included in maturity groups based upon stated maturity date. At March 31, 2013, $132.4 million of the Bank's mortgage-backed securities were pass-through securities and $115.6 million were collateralized mortgage obligations. At December 31, 2012, $107.3 million of the Bank's mortgage-backed securities were pass-through securities and $123.6 million were collateralized mortgage obligations. Actual maturity will vary based on repayment of the underlying mortgage loans.

Gross realized gains on the sale of securities for the three months ended March 31, 2013 were $4,000. There were no losses on the sale of securities available-for-sale for the three months ended March 31, 2013. There were no gains or losses for the three months ended March 31, 2012.

Investment securities with carrying values of approximately $84,814,747 and $88,652,919 at March 31, 2013 and December 31, 2012, respectively, were pledged as collateral for public deposits and for other purposes as required or permitted by law.

The following table presents the gross unrealized losses and fair value of investment securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at March 31, 2013 and December 31, 2012. Securities that have been in a loss position for twelve months or more at March 31, 2013 include one collateralized mortgage obligation and one private label collateralized mortgage obligation. The key factors considered in evaluating the collateralized mortgage obligations, private label collateralized mortgage obligations, and municipal securities were cash flows of the investment and the assessment of other relative economic factors. Securities that have been in a loss position for twelve months or more at December 31, 2012 include three collateralized mortgage obligations, one private label collateralized mortgage obligation and two other securities. The unrealized losses relate to securities that have incurred fair value reductions due to a shift in demand from non-governmental securities and municipals to U.S. Treasury bonds and governmental agencies due to credit market concerns. The unrealized losses are not likely to reverse until market interest rates decline to the levels that existed when the securities were purchased. None of the unrealized losses relate to the marketability of the securities or the issuer's ability to honor redemption obligations. It is not more likely than not that the Company will have to sell the investments before recovery of their amortized cost bases. For the three months ended March 31, 2013, there were no securities available-for-sale deemed to be other than temporarily impaired (“OTTI”).

If management determines that an investment has experienced an other than temporary impairment, the loss is recognized in the income statement.
