Note 4. Securities Available-For-Sale

The Company’s securities are classified as available-for-sale at March 31, 2017 and December 31, 2016. Securities available-for-sale are reported at fair value with unrealized gains or losses included in equity, net of tax. Accordingly, the carrying value of such securities reflects their fair value as of March 31, 2017 and December 31, 2016. Fair value is based upon either quoted market prices, or in certain cases where there is limited activity in the market for a particular instrument, assumptions are made to determine their fair value. See Note 7 of the Notes to Consolidated Financial Statements for a further discussion.

Transfers of debt securities from the held-to-maturity category to the available-for-sale category are made at fair value at the date of transfer. For transfers from the available-for-sale category to the held-to maturity category the unrealized holding gain or loss at the date of transfer remains in accumulated other comprehensive income and in the carrying value of the held-to-maturity security. Unrealized holding gains or losses that remain in accumulated other comprehensive income are amortized or accreted out of other comprehensive income with an offsetting entry to interest income as a yield adjustment through earnings over the remaining terms of the securities. For transfers from the held-to-maturity category to the available-for-sale category unrealized holding gain or loss at the date of the transfer shall be recognized in accumulated other comprehensive income, net of applicable taxes.

During the year ended December 31, 2016, the Company transferred all securities previously categorized as held-to-maturity to available-for-sale classification. The transfer resulted in an increase of approximately $210 million in amortized cost basis of available-for-sale securities and resulted in a net increase to accumulated other comprehensive income of $7.4 million, net of tax. The transfer enhances liquidity and increases flexibility with regard to asset-liability management and balance sheet composition. As a result of the transfer, the Company believes it has tainted its held-to-maturity classification and judgment will be required in the future in determining when circumstances have changed such that management can assert that it has the intent and ability to hold debt securities to maturity. Based on this guidance, the Company does not expect to classify any securities as held-to-maturity within the near future.

The Company reviews all securities for potential recognition of other-than-temporary impairment. The Company maintains a watch list for the identification and monitoring of securities experiencing problems that require a heightened level of review. This could include credit rating downgrades.

The Company’s assessment of whether an impairment in the portfolio is other-than temporary includes factors such as whether the issuer has defaulted on scheduled payments, announced restructuring and/or filed for bankruptcy, has disclosed severe liquidity problems that cannot be resolved, disclosed deteriorating financial condition or sustained significant losses.

Temporarily Impaired Securities

The Company does not believe that any of the unrealized losses, which were comprised of 82 and 84 securities as of March 31, 2017 and December 31, 2016, respectively, represent an other-than-temporary impairment (“OTTI”). The gross unrealized losses associated with U.S. Treasury and agency securities, federal agency obligations, mortgage-backed securities, corporate bonds, tax-exempt securities, asset-backed securities, trust preferred securities, mutual funds and equity securities are not considered to be other-than-temporary because these unrealized losses are related to changes in interest rates and do not affect the expected cash flows of the underlying collateral or issuer.

Factors which may contribute to unrealized losses include credit risk, market risk, changes in interest rates, economic cycles, and liquidity risk. The magnitude of any unrealized loss may be affected by the relative concentration of the Company’s investment in any one issuer or industry. The Company has established policies to reduce exposure through diversification of the securities portfolio including limits on concentrations to any one issuer. The Company believes the securities portfolio is prudently diversified.

The unrealized losses included in the tables below are primarily related to changes in interest rates and credit spreads. All of the Company’s securities are performing and are expected to continue to perform in accordance with their respective contractual terms and conditions. These are largely intermediate duration holdings and, in certain cases, monthly principal payments can further reduce loss exposure resulting from an increase in rates.

The Company evaluates all securities with unrealized losses quarterly to determine whether the loss is other-than-temporary. Unrealized losses in the corporate debt securities category consist primarily of senior unsecured corporate debt securities issued by large financial institutions, insurance companies and other corporate issuers. Single issuer corporate trust preferred securities are also included, and in the case of one holding the market valuation loss is largely based upon the floating rate coupon and corresponding market valuation. Neither that trust preferred issuer, nor any other corporate issuers, have defaulted on interest payments. The unrealized loss in equity securities consists of losses on other bank equities. The decline in fair value is due in large part to the lack of an active trading market for these securities, changes in market credit spreads and rating agency downgrades. Management concluded that these securities were not other-than-temporarily impaired at March 31, 2017.

In determining whether or not securities are OTTI, the Company must exercise considerable judgment. Accordingly, there can be no assurance that the actual results will not differ from the Company’s judgments and that such differences may not require the future recognition of OTTI charges that could have a material effect on the Company’s financial position and results of operations. In addition, the value of, and the realization of any loss on, a security is subject to numerous risks as cited above.

The following tables indicate gross unrealized losses not recognized in income and fair value, aggregated by investment category and the length of time individual securities have been in a continuous unrealized loss position at March 31, 2017 and December 31, 2016:
