Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. The majority of our held-to-maturity investment portfolio consists of securities issues by U.S. government entities and agencies and we consider the risk of credit loss to be zero and, therefore, we do not record an ACL. The Company's non-government backed securities include private label CMO and MBS and bank subordinated debt. Accrued interest receivable on held-to-maturity debt securities totaled $0.5 million at March 31, 2023 and is excluded from the estimate of credit losses. Refer to Note 1 - Organization and Summary of Significant Accounting Policies for additional information on the Company’s methodology on estimating credit losses. The following table presents the activity in the allowance for credit losses for debt securities held-to-maturity by major security type for the three months ended March 31, 2023:
