Our Company’s available for sale portfolio consisted of approximately 390 securities at September 30, 2012. One of these securities with an unrealized loss of $164 had been in the loss position for 12 months or longer. The unrealized loss included in other comprehensive income at September 30, 2012 was caused by interest rate fluctuations. Our Company’s available for sale portfolio consisted of approximately 365 securities at December 31, 2011. One of these securities with an unrealized loss of $294 had been in the loss position for 12 months or longer. The unrealized loss included in other comprehensive income at December 31, 2011 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 September 30, 2012 and December 31, 2011, respectively. During the three and nine months ended September 30, 2012, there was a $26,000 realized gain from sales of securities recognized in earnings. During the three and nine months ended September 30, 2011, there were no proceeds from sales of securities and no components of investment securities gains and losses which have been recognized in earnings.
