The severity of these unrealized losses based on their underlying cost basis was as follows at December 31, 2021: 2.29% for agency - GSE, 1.46% for total MBS-GSE residential; and 1.79% for municipals. 26 of these securities had been in an unrealized loss position in excess of 12 months. Management has no intent to sell any securities in an unrealized loss position as of December 31, 2021.Management believes the cause of the unrealized losses is related to changes in interest rates, instability in the capital markets or the limited trading activity due to illiquid conditions in the debt market and is not directly related to credit quality. Quarterly, management conducts a formal review of investment securities for the presence of other than temporary impairment (OTTI). The accounting guidance related to OTTI requires the Company to assess whether OTTI is present when the fair value of a debt security is less than its amortized cost as of the balance sheet date. Under those circumstances, OTTI is considered to have occurred if: (1) the entity has the intent to sell the security; (2) more likely than not the entity will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost. The accounting guidance requires that credit-related OTTI be recognized in earnings while non-credit-related OTTI on securities not expected to be sold be recognized in other comprehensive income (OCI). Non-credit-related OTTI is based on other factors affecting market value, including illiquidity.The Company’s OTTI evaluation process also follows the guidance set forth in topics related to debt securities. The guidance set forth in the pronouncements require the Company to take into consideration current market conditions, fair value in relationship to cost, extent and nature of changes in fair value, issuer rating changes and trends, volatility of earnings, current analysts’ evaluations, all available information relevant to the collectability of debt securities, the ability and intent to hold investments until a recovery of fair value which may be to maturity and other factors when evaluating for the existence of OTTI. The guidance requires that credit-related OTTI be recognized as a realized loss through earnings when there has been an adverse change in the holder’s expected cash flows such that the full amount (principal and interest) will probably not be received. This requirement is consistent with the impairment model in the guidance for accounting for debt securities.For all debt securities, as of December 31, 2021, the Company applied the criteria provided in the recognition and presentation guidance related to OTTI. That is, management has no intent to sell the securities and nor any conditions were identified by management that, more likely than not, would require the Company to sell the securities before recovery of their amortized cost basis. The results indicated there was no presence of OTTI in the Company’s security portfolio. In addition, management believes the change in fair value is attributable to changes in interest rates. ‎
