Investment Securities

Note 4 - Investment Securities

The Company’s investment securities are classified as available-for-sale at December 31, 2018 and December 31, 2017. Investment securities available-for-sale are reported at fair value with unrealized gains or losses included in stockholders’ equity, net of tax. Accordingly, the carrying value of such securities reflects their fair value as of December 31, 2018 and December 31, 2017. 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 22 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, a component of stockholders’ equity and in the carrying value of the held-to-maturity investment 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 tax.

The following tables present information related to the Company’s portfolio of securities available-for-sale at December 31, 2018 and 2017.

Investment securities having a carrying value of approximately $151.5 million and $157.8 million at December 31, 2018 and December 31, 2017, respectively, were pledged to secure public deposits, borrowings, repurchase agreements, Federal Reserve Discount Window borrowings and Federal Home Loan Bank advances and for other purposes required or permitted by law. As of December 31, 2018 and December 31, 2017, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity.

The following table presents information for investments in securities available-for-sale at December 31, 2018, based on scheduled maturities. Actual maturities can be expected to differ from scheduled maturities due to prepayment or early call options of the issuer. Securities not due at a single maturity date are shown separately.

Other-than-Temporarily Impaired Investments

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 a 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 Investments

The Company does not believe that any of the unrealized losses, which were comprised of 148 and 112 investment securities as of December 31, 2018 and December 31, 2017, respectively, represent an other-than-temporary impairment. The gross unrealized losses associated with U.S. Treasury and agency securities, federal agency obligations, mortgage-backed securities, corporate bonds, obligations of U.S. states and political subdivisions, and asset-backed securities, are not considered to be other-than-temporary because management believes 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 investment portfolio including limits on concentrations to any one issuer. The Company believes the investment 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 investment 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, none of which have defaulted on interest payments. The decline in fair value is due in large part to changes in market credit spreads and movements in market interest rates. Management concluded that these securities were not other-than-temporarily impaired at December 31, 2018.

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 other-than-temporary impairment 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, an investment 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 December 31, 2018 and 2017. There were no investments held-to-maturity as of December 31, 2018 and 2017.
