The amortized costs and fair values in the preceding table exclude $18 million and $23 million of accrued interest on available-for-sale securities as of September 30, 2025 and 2024, respectively, which was included in “Other receivables, net” on our Consolidated Statements of Financial Condition.

See Note 6 for additional information regarding available-for-sale securities pledged with the FHLB and FRB.
The following table details the contractual maturities, amortized costs, fair values and current yields for our available-for-sale securities.  Weighted-average yields are calculated on a taxable-equivalent basis based on estimated annual income divided by the average amortized cost of these securities. Since our MBS and CMO available-for-sale securities are backed by mortgages, actual maturities may differ from contractual maturities because borrowers may have the right to prepay obligations without prepayment penalties. As a result, the weighted-average life of our available-for-sale securities portfolio, after factoring in estimated prepayments, was approximately 3.8 years as of September 30, 2025.

At September 30, 2025, debt securities we held in excess of ten percent of our equity included those issued by the Federal National Home Mortgage Association and Federal Home Loan Mortgage Corporation with amortized costs of $3.51 billion and $2.15 billion, respectively, and fair values of $3.24 billion and $1.95 billion, respectively.

During the year ended September 30, 2025, we received proceeds of $78 million from sales of available-for-sale securities resulting in $2 million of losses. Such losses were reclassified from AOCI to “Other” revenue on the Consolidated Statements of Income and Comprehensive Income during the year ended September 30, 2025. There were no sales of available-for-sale securities during the years ended September 30, 2024 and 2023.
