For available for sale securities, the Company assesses whether a loss is from credit or other factors and considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost, a credit loss would be recorded through an allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis.

The following table presents the activity in the allowance for credit losses on debt securities available for sale for the three and six months ended June 30, 2022:

For held to maturity securities, management measures expected credit losses on a collective basis by major security type. All of the mortgage-backed securities are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses and, therefore, the expectation of non-payment is zero and the Company is not required to estimate an allowance for credit losses on these securities under the CECL standard. All these securities reflect a credit quality rating of AAA by Moody's Investors Service.

The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of debt held to maturity. Accrued interest receivable on debt securities held to maturity is reported as a component of accrued interest receivable on the Consolidated Statement of Financial Condition, which totaled $920,000 at June 30, 2022, and is excluded from the estimate of credit losses.
