At June 30, 2016, mortgage-backed securities (“MBS”) with an estimated par value of $59.6 million and a fair value of $62.1 million were pledged as collateral for the Bank’s three reverse repurchase agreements which totaled $28.5 million and homeowner’s association (“HOA”) reverse repurchase agreements which totaled $16.8 million.

The Company reviews individual securities classified as available-for-sale to determine whether a decline in fair value below the amortized cost basis is temporary because (i) those declines were due to interest rate changes and not to a deterioration in the creditworthiness of the issuers of those investment securities, and (ii) we have the ability to hold those securities until there is a recovery in their values or until their maturity.

If it is probable that the Company will be unable to collect all amounts due according to contractual terms of the debt security not impaired at acquisition, an other-than-temporary ("OTTI") shall be considered to have occurred. If an OTTI occurs, the cost basis of the security will be written down to its fair value as the new cost basis and the write down accounted for as a realized loss.

The Company did not realize any OTTI losses for the three months ended June 30, 2016 or June 30, 2015. The Company realized OTTI losses of $207,000 for the three months ended March 31, 2016. The OTTI loss relates to a CRA investment purchased in June of 2014 with a par value of $50, and a book value of $500,000. In March of 2016 the shareholders of the investment voted to approve a sale of the institution at a per share acquisition price less the Bank's book value, with an expected closing by mid-2016. As a result, the Bank's current holdings were written down and the loss recognized.

During the six months ended June 30, 2016, the Company realized OTTI losses of $207,000. The Company did not realize any OTTI losses for the six months ended June 30, 2015.

During the three months ended June 30, 2016, March 31, 2016 and June 30, 2015, the Company recognized gross gains on sales of available-for-sale securities in the amount of $532,000, $762,000 and $146,000, respectively. During the three months ended June 30, 2016, the Company did not recognize any gross losses on the sales of available-for sale securities. During the three months ended March 31, 2016 and June 30, 2015, the Company recognized gross losses on sales of available-for-sale securities in the amount of $9,000 and $7,000, respectively. The Company had net proceeds from the sale of available-for-sale securities of $21.1 million and $186 million and $7.3 million during the three months ended June 30, 2016, March 31, 2016 and June 30, 2015, respectively.
