NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 4 – Investment Securities – (continued)

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 21 and 53 securities as of December 31, 2020 and December 31, 2019, 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, and asset-backed 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.

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.
