The table below summarizes, as of June 30, 2026, the fair value of our investment securities by major security type and contractual maturity as well as the total fair value, amortized cost basis and weighted-average yields of our investment securities by contractual maturity. Since borrowers may have the right to call or prepay certain obligations, the expected maturities of our securities are likely to differ from the scheduled contractual maturities presented below. The weighted-average

yield below represents the effective yield for the investment securities presented on a pre-tax basis and is calculated based on the amortized cost basis of each security, inclusive of the contractual coupon, the impact of any premium amortization or discount accretion and any basis adjustments resulting from discontinued hedge accounting relationships. The effective yield is calculated to the contractural maturity or to the earliest call date for certain callable debt securities.
