Securities available for sale in unrealized loss positions are evaluated quarterly for impairment related to credit losses. For securities available for sale in an unrealized loss position, we first assess whether we intend to sell, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities available for sale that do not meet this criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, we consider the extent to which fair value is less than amortized cost, adverse conditions specifically related to the security and the issuer and the impact of changes in market interest rates on the market value of the security, among other factors. If this assessment indicates that a credit loss exists, we compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an ACL is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income, net of applicable taxes. No ACL for securities available for sale was needed at March 31, 2021. Accrued interest receivable on securities available for sale totaled $5.1 million at March 31, 2021 and is excluded from the estimate of credit losses.

U.S. agency, U.S. agency residential mortgage-backed and U.S. agency commercial mortgage-backed securities — at March 31, 2021, we had 25 U.S. agency, 57 U.S. agency residential mortgage-backed and two U.S. agency commercial mortgage-backed securities whose fair value is less than amortized cost. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses. The unrealized losses are largely attributed to widening spreads to Treasury bonds and/or an increase in interest rates since acquisition.

Private label mortgage backed, other asset backed and corporate securities — at March 31, 2021, we had 11 private label mortgage backed, 20 other asset backed and 19 corporate securities whose fair value is less than amortized cost. The unrealized losses are primarily due to credit spread widening and/or an increase in interest rates since acquisition.

Obligations of states and political subdivisions — at March 31, 2021, we had 107 municipal securities whose fair value is less than amortized cost. The unrealized losses are primarily due to an increase in interest rates since acquisition.

Trust preferred securities — at March 31, 2021, we had two trust preferred securities whose fair value is less than amortized cost. Both of our trust preferred securities are single issue securities issued by a trust subsidiary of a bank holding company. The pricing of trust preferred securities has suffered from credit spread widening. One of the securities is rated by a major rating agency as investment grade while the other one is non-rated. The non-rated issue is a relatively small bank and was never rated. The issuer of this non-rated trust preferred security, which had a total amortized cost of $1.0 million and total fair value of $0.92 million as of March 31, 2021, continues to have satisfactory credit metrics and make interest payments.

At March 31, 2021 management does not intend to liquidate any of the securities discussed above and it is more likely than not that we will not be required to sell these securities prior to recovery of these unrealized losses.

We recorded no credit related charges in our Condensed Consolidated Statements of Operations related to securities available for sale during the three month periods ended March 31, 2021 and 2020, respectively.
