We did not sell any available-for-sale securities during the first and second quarters of 2016. During the three months ended June 30, 2015, we sold certain available-for-sale investment securities for gross proceeds of $117.5 million. Gross realized losses on the sale of the available-for-sale investment securities were $1.9 million during the three months ended June 30, 2015. The specific identification method was used as the basis for determining the cost of all securities sold. We did not sell any available-for-sale securities during the first quarter of 2015. Investment securities of $1.04 billion and $1.00 billion at June 30, 2016 and December 31, 2015, respectively, were pledged to secure public funds on deposit and other long-term debt and short-term borrowings. Provided below is a summary of the 13 and 155 investment securities which were in an unrealized loss position at June 30, 2016 and December 31, 2015, respectively, segregated by continuous length of impairment.

Other-Than-Temporary Impairment (“OTTI”) Unrealized losses for all investment securities are reviewed to determine whether the losses are deemed “other-than-temporary.” Investment securities are evaluated for OTTI on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in their value below amortized cost is other-than-temporary. In conducting this assessment, we evaluate a number of factors including, but not limited to:
• | The length of time and the extent to which fair value has been less than the amortized cost basis;
• | Adverse conditions specifically related to the security, an industry, or a geographic area;
• | The historical and implied volatility of the fair value of the security;
• | The payment structure of the debt security and the likelihood of the issuer being able to make payments;
• | Failure of the issuer to make scheduled interest or principal payments;
• | Any rating changes by a rating agency; and
• | Recoveries or additional declines in fair value subsequent to the balance sheet date.
The term “other-than-temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value are not necessarily favorable, or that there is a general lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. Once a decline in value is determined to be other-than-temporary, the value of the security is reduced and a corresponding charge to earnings is recognized for anticipated credit losses. Because we have no intent to sell securities in an unrealized loss position and it is not more likely than not that we will be required to sell such securities before recovery of its amortized cost basis, we do not consider our investments to be other-than-temporarily impaired.
