Schedule of Amortized Cost and Fair Value of Securities Available for Sale
The amortized cost and fair value of AFS debt securities are presented in the table below. There was no ACL associated with the AFS portfolio at September 30, 2026 and December 31, 2025. Accrued interest receivable on AFS debt securities totaled $16.3 million at September 30, 2026 and $16.2 million at December 31, 2025, and is excluded from the estimate of credit losses and assessed separately in other assets in the Consolidated Balance Sheets. Accordingly, we have excluded accrued interest receivable from both the fair value and amortized cost basis of AFS debt securities.
