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 March 31, 2026. The schedule does not reflect the effects of interest rate resets or fair value hedges. Additionally, the remaining contractual principal maturities shown do not represent the portfolio's duration, as they exclude expected prepayments or amortization, which typically result in measured durations that are significantly shorter than contractual maturities.
