4.	Securities (continued)

Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic, market or other conditions warrant such evaluation. Consideration is given to: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions and (4) whether the Corporation has the intent to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis. If the Corporation intends to sell an impaired security, or if it is more likely than not the Corporation will be required to sell the security before its anticipated recovery, the Corporation records an other-than-temporary loss in an amount equal to the entire difference between fair value and amortized cost. Otherwise, only the credit portion of the estimated loss on debt securities is recognized in earnings, with the other portion of the loss recognized in other comprehensive income. For equity securities determined to be other-than-temporarily impaired, the entire amount of impairment is recognized through earnings.

There was one equity security in an unrealized loss position for more than 12 months as of December 31, 2016. Equity securities owned by the Corporation consist of common stock of various financial service providers. This investment security is in unrealized loss positions as a result of the illiquid nature of the stock. The Corporation does not invest in these securities with the intent to sell them for a profit in the near term. For investments in equity securities, in addition to the general factors mentioned above for determining whether the decline in market value is other-than-temporary, the analysis of whether an equity security is other-than-temporarily impaired includes a review of the profitability, capital adequacy and other relevant information available to determine the financial position and near term prospects of each issuer. The results of analyzing the aforementioned metrics and financial fundamentals suggest recovery of amortized cost in the near future. Based on that evaluation, and given that the Corporation’s current intention is not to sell any impaired security and it is more likely than not it will not be required to sell this security before the recovery of its amortized cost basis, the Corporation does not consider the equity security with an unrealized loss as of December 31, 2016 to be other-than-temporarily impaired.

There were 128 debt securities in an unrealized loss position as of December 31, 2016, of which 13 were in an unrealized loss position for more than 12 months. Of these 128 securities, 66 were state and political subdivisions securities, 24 were collateralized mortgage obligations (issued by U.S. government sponsored entities), 17 were mortgage-backed securities, 8 were corporate securities, 8 were U.S. government sponsored entities and agencies securities and 5 were U.S. Treasury securities. The unrealized losses associated with these securities were not due to the deterioration in the credit quality of the issuer that is likely to result in the non-collection of contractual principal and interest, but rather have been caused by a rise in interest rates from the time the securities were purchased. Based on that evaluation and other general considerations, and given that the Corporation’s current intention is not to sell any impaired securities and it is more likely than not it will not be required to sell these securities before the recovery of its amortized cost basis, the Corporation does not consider the debt securities with unrealized losses as of December 31, 2016 to be other-than-temporarily impaired.
