Management evaluates securities for impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. All debt securities available for sale in an unrealized loss position as of December 31, 2022 continue to perform as scheduled and management does not believe that there is a credit loss or that a provision for credit losses is necessary. Also, as part of management's evaluation of its intent and ability to hold investments for a period of time sufficient to allow for any anticipated recovery in the market, management considers its investment strategy, cash flow needs, liquidity position, capital adequacy and interest rate risk position. Management does not currently intend to sell the securities within the portfolio and it is not more-likely-than-not that securities will be required to be sold. See "Note 1 – Summary of Significant Accounting Policies" in our 2022 Form 10-K for further discussion.

Management continues to monitor all of its securities with a high degree of scrutiny. There can be no assurance that management will not conclude in future periods that conditions existing at that time indicate some or all of its securities may be sold or would require a charge to earnings as a provision for credit losses in such periods.

Management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on investment securities and does not record an ACL on accrued interest receivable. As of December 31, 2022, the accrued interest receivable for debt securities available for sale was $552.
