The factors considered in evaluating securities for impairment include whether the Bank intends to sell the security, whether it is more likely than not that the Bank will be required to sell the security before recovery of its amortized cost basis, and whether the Bank expects to recover the security’s entire amortized cost basis. These unrealized losses are primarily attributable to current financial market conditions for these types of investments, particularly changes in interest rates, causing bond prices to decline, and are not attributable to credit deterioration.

At December 31, 2021, there were seven collateralized mortgage backed securities with fair values totaling $11.9 million, ten municipal securities with a fair value of $8.1 million and eleven subordinated debt securities with fair values of $4.7 million considered temporarily impaired and in an unrealized loss position of less than 12 months. At December 31, 2021, there were nine U.S. government agencies with fair values totaling approximately $5.4 million, one collateralized mortgage backed security with a fair value totaling $12.0 million and two municipal securities with a fair value of $3.5 million that were in an unrealized loss position of more than 12 months. The Bank does not consider any of the securities in the available for sale portfolio to be other-than-temporarily impaired at December 31, 2021 and December 31, 2020. There were no securities sold during 2021 or 2020.

All municipal securities originally purchased as available for sale were transferred to held to maturity during 2013. The unrealized loss on the securities transferred to held to maturity is being amortized over the expected life of the securities. The unamortized, unrealized loss, before tax, at December 31, 2021 and December 31, 2020 was $29,016 and $54,836, respectively.
