The total available for sale portfolio consisted of approximately 316 securities at December 31, 2015. The portfolio included 71 securities having an aggregate fair value of $147.5 million that were in a loss position at December 31, 2015. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer totaled $45.3 million at fair value. The $2.0 million aggregate unrealized loss included in accumulated other comprehensive income at December 31, 2015 was caused by interest rate fluctuations.

The total available for sale portfolio consisted of approximately 300 securities at December 31, 2014. The portfolio included 74 securities having an aggregate fair value of $82.2 million that were in a loss position at December 31, 2014. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer totaled $65.2 million at fair value. The $1.3 million aggregate unrealized loss included in accumulated other comprehensive income at December 31, 2014 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, 2015 and 2014. In addition, the Company does not have the intent to sell these investments over the period of recovery, and it is not more likely than not that it will be required to sell such investment securities.
