Schedule Of Contractual Maturities
The amortized cost and estimated fair value of AFS debt securities as of March 31, 2025, by contractual maturity, are shown below.  Actual principal repayments may differ from contractual maturities due to prepayment or early call privileges by the issuer. In the case of MBS, borrowers on the underlying loans generally have the right to prepay their loans without penalty. For this reason, MBS are not included in the maturity category in the table below.
