The Bank has no investment in a single issuer that exceeds 10% of shareholders equity. The amortized cost and estimated fair value of debt securities at December 31, 2021, by contractual maturity are shown below. Actual maturities may differ from contractual maturities because of prepayment or call options embedded in the securities. Mortgage-backed and asset-backed securities without defined maturity dates are reported on a separate line.

For securities with an unrealized loss, Management applies a systematic methodology in order to perform an assessment of the potential for other-than-temporary impairment. In the case of debt securities, investments considered for other-than-temporary impairment: (1) had a specified maturity or repricing date, (2) were generally expected to be redeemed at par, and (3) were expected to achieve a recovery in market value within a reasonable period of time. In addition, the Bank considers whether it intends to sell these securities or whether it will be forced to sell these securities before the earlier of amortized cost recovery or maturity. The impairment identified on debt securities and subject to assessment at December 31, 2021, was deemed to be temporary and required no further adjustments to the financial statements, unless otherwise noted.
