The total available for sale portfolio consisted of approximately 355 securities at December 31, 2017. The portfolio included 277 securities having an aggregate fair value of $207.9 million that were in a loss position at December 31, 2017. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer had a fair value of $114.6 million at December 31, 2017. The $3.3 million aggregate unrealized loss included in accumulated other comprehensive loss at December 31, 2017 was caused by interest rate fluctuations.

The total available for sale portfolio consisted of approximately 298 securities at December 31, 2016. The portfolio included 216 securities having an aggregate fair value of $188.6 million that were in a loss position at December 31, 2016. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer had a fair value of $3.7 million at December 31, 2016. The $3.4 million aggregate unrealized loss included in accumulated other comprehensive loss at December 31, 2016 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, 2017 and 2016, respectively. In the absence of changes in credit quality of these investments, the fair value is expected to recover on all debt securities as they approach their maturity date, or re-pricing date or if market yields for such investments decline. 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 the Company will be required to sell such investment securities.

The table presents the components of investment securities gains and losses, which have been recognized in earnings:

(in thousands)	2017			2016			2015
Gains realized on sales		$	38		$	623		$	8
Losses realized on sales			(33)			(21)			0
Other-than-temporary impairment recognized			0			0			0
Investment securities gains		$	5		$	602		$	8
