At June 30, 2025, investment securities with carrying values of $2.70 billion were pledged to secure various types of deposits, including $1.09 billion of public funds. In addition, investment securities with carrying values of $2.03 billion were pledged to secure $511 million for repurchase agreements, $1.47 billion for unused borrowing capacity and approximately $57 million for other purposes as required or permitted by law. At December 31, 2024, investment securities with carrying values of $2.79 billion were pledged to secure various types of deposits, including $1.18 billion of public funds. In addition, investment securities with carrying values of $1.63 billion were pledged to secure $372.5 million for repurchase agreements, $1.8 billion for outstanding borrowings, $796 million for unused borrowing capacity and approximately $51 million for other purposes as required or permitted by law. The amortized cost and fair value of debt securities at June 30, 2025, by contractual maturity, are shown in the table below. Although mortgage-backed and CMO/REMIC securities have weighted average remaining contractual maturities of approximately 24 years, expected maturities will differ from contractual maturities because borrowers may have the right to prepay such obligations without penalty. Mortgage-backed and CMO/REMIC securities are included in maturity categories based upon estimated average lives which incorporate estimated prepayment speeds.
