 30, 2025 and December 31, 2024, respectively. Accrued interest receivable on AFS securities totaled $23.3 million and $21.4 million at September 30, 2025 and December 31, 2024, respectively. Accrued interest receivable on both HTM and AFS securities is included in interest receivable on the consolidated balance sheets.On a quarterly basis, the Corporation refreshes the credit quality of each HTM security. The Company monitors the credit quality of HTM securities through credit ratings provided by S&P and Moody’s. Investment grade securities are rated BBB- or higher by S&P, or Baa3 or higher by Moody’s, and are generally considered by the rating agencies and market participants to be of low credit risk. As of September 30, 2025 and December 31, 2024, the Corporation's HTM portfolio contained all investment grade securities except for securities that were not rated which were individually reviewed noting no credit quality issues.The Corporation holds U.S. Treasury, municipal, and mortgage-related securities issued by the U.S. government or a GSE which are backed by the full faith and credit of the U.S. government and private-label residential mortgage-related securities that have credit enhancement which covers the first 15% of losses and, as a result, no allowance for credit losses has been recorded related to these securities. The allowance for credit losses on HTM securities was $0.1 million at both September 30, 2025 and December 31, 2024, attributable entirely to the Corporation's municipal securities, included in HTM investment securities, net, at amortized cost on the consolidated balance sheets.
