The primary purpose of the investment portfolio is to generate income, diversify earning assets, and meet liquidity needs of the Company through readily saleable financial instruments. The portfolio is made up primarily of fixed rate bonds, whose prices move inversely with rates. At the end of any accounting period, the investment portfolio has unrealized gains and losses. The Company monitors the portfolio, which is subject to liquidity needs, market rate changes, and credit risk changes, to see if adjustments are needed. The primary concern in a loss situation is the credit quality of the business or entity behind the instrument. The primary cause of unrealized losses is the increase in market interest rates over the yields available at the time the securities were purchased.

At December 31, 2013, the Company does not consider any security in an unrealized loss position to be other-than-temporarily impaired.

U.S. Government and federal agency securities. The unrealized losses on nineteen of the Company’s investments in obligations of the U.S. government were caused by increases in market interest rates over the yields available at the time the securities were purchased.  The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2013.

Mortgage-backed securities. The unrealized losses on ten of the Company’s investments in government-sponsored entity mortgage-backed securities were caused by increases in market interest rates over the yields available at the time the securities were purchased.  Because the decline in market value is attributable to changes in interest rates and not credit quality, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2013.

Municipal securities. The unrealized losses on thirty-six of the Company’s investments in obligations of municipal securities were caused by increases in market interest rates over the yields available at the time the securities were purchased. All municipal securities are investment grade. Because the decline in market value is attributable to changes in interest rates, credit spreads, ratings and not credit quality, and because the Company does not intend to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2013.

The following tables demonstrate the unrealized loss position of securities available for sale at December 31, 2013 and 2012.
