The following table presents the weighted average yields for investment securities available for sale and held to maturity at September 30, 2025, segregated by major category with ranges of contractual maturities. The weighted average yields represent the yields of the underlying securities as of the specified date, September 30, 2025, within the specified maturity range. The weighted average yield on the portfolio was calculated using security-level annualized yields based on book yield to maturity and takes into account amortization of premiums and accretion of discounts. The total weighted average yields for investment securities available for sale and held to maturity are based on the underlying weighted average amortized cost.
