Schedule of Contractual Maturities Debt Securities
The following schedule presents the amortized cost and weighted average yields of debt securities, categorized by the remaining contractual maturity of principal payments at September 30, 2025. The schedule does not reflect the impact of interest rate resets or fair value hedges. Additionally, the remaining contractual principal maturities presented do not represent the portfolio's duration, as they do not incorporate expected prepayments or amortization, which generally result in measured durations that are shorter than contractual maturities.
