The total available for sale portfolio consisted of approximately 348 securities at December 31, 2013. The portfolio included 96 securities having an aggregate fair value of $115.1 million that were in a loss position at December 31, 2013. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer totaled $6.4 million at fair value. The $4.2 million aggregate unrealized loss included in accumulated other comprehensive income at December 31, 2013 was caused by interest rate fluctuations. The total available for sale portfolio consisted of approximately 380 securities at December 31, 2012. The portfolio included 14 securities having an aggregate fair value of $8.0 million that were in a loss position at December 31, 2012. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer totaled $150,000 at fair value. The $28,000 aggregate unrealized loss included in other comprehensive income at December 31, 2012 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 December 31, 2013 and 2012, respectively.
