U.S. Government and federal agency securities. The unrealized losses on 13 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 June 30, 2013.

Mortgage-backed securities. The unrealized losses in 7 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, 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 June 30, 2013.

Municipal securities. The unrealized losses on the Company’s 21 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 June 30, 2013.

The following tables demonstrate the unrealized loss position of securities available for sale at June 30, 2013 and December 31, 2012.
