 NOTE 3  Investment Securities
The Company’s held-to-maturity investment securities are carried at historical cost, adjusted for amortization of premiums and accretion of discounts. The Company’s available-for-sale investment securities are carried at fair value with unrealized net gains or losses reported within accumulated other comprehensive income (loss) in shareholders’ equity.
The amortized cost, gross unrealized holding gains and losses, and fair value of held-to-maturity and available-for-sale investment securities were as follows:

Investment securities with a fair value of $18.2 billion at June 30, 2025, and $18.8 billion at December 31, 2024, were pledged to secure public, private and trust deposits, repurchase agreements and for other purposes required by contractual obligation or law. Included in these amounts were securities where the Company and certain counterparties have agreements granting the counterparties the right to sell or pledge the securities. Investment securities securing these types of arrangements had a fair value of $351 million at June 30, 2025, and $320 million at December 31, 2024.

The Company conducts a regular assessment of its available-for-sale investment securities with unrealized losses to determine whether all or some portion of a security’s unrealized loss is related to credit and an allowance for credit losses is necessary. If the Company intends to sell or it is more likely than not the Company will be required to sell an investment security, the amortized cost of the security is written down to fair value. When evaluating credit losses, the Company considers various factors such as the nature of the investment security, the credit ratings or financial condition of the issuer, the extent of the unrealized loss, expected cash flows of underlying collateral, the existence of any government or agency guarantees, and market conditions. The Company measures the allowance for credit losses using market information where available and discounting the cash flows at the original effective rate of the investment security. The allowance for credit losses is adjusted each period through earnings and can be subsequently recovered. The allowance for credit losses on the Company’s available-for-sale investment securities was immaterial at June 30, 2025 and December 31, 2024.
At June 30, 2025, certain investment securities had a fair value below amortized cost. The following table shows the gross unrealized losses excluding portfolio level basis adjustments and fair value of the Company’s available-for-sale investment securities with unrealized losses, aggregated by investment category and length of time the individual investment securities have been in continuous unrealized loss positions, at June 30, 2025:

These unrealized losses primarily relate to changes in interest rates and market spreads subsequent to purchase of these available-for-sale investment securities. U.S. Treasury and agencies securities and agency mortgage-backed securities are issued, guaranteed or otherwise supported by the United States government. The Company’s obligations of state and political subdivisions are generally high grade. Accordingly, the Company does not consider these unrealized losses to be credit-related and an allowance for credit losses is not necessary. In general, the issuers of the investment securities are contractually prohibited from prepayment at less than par, and the Company did not pay significant purchase premiums for these investment securities. At June 30, 2025, the Company had no plans to sell investment securities with unrealized losses, and believes it is more likely than not it would not be required to sell such investment securities before recovery of their amortized cost.
During the three and six months ended June 30, 2025 and 2024, the Company did not purchase any investment securities that had more-than-insignificant credit deterioration.
Predominately all of the Company’s held-to-maturity investment securities are U.S. Treasury and agencies securities and highly rated agency mortgage-backed securities that are guaranteed or otherwise supported by the United States government and have no history of credit losses. Accordingly the Company does not expect to incur any credit losses on held-to-maturity investment securities and has no allowance for credit losses recorded for these securities.

(a)Information related to asset and mortgage-backed securities included above is presented based upon weighted-average maturities that take into account anticipated future prepayments.
(b)The weighted-average maturity of total held-to-maturity investment securities was 8.7 years at December 31, 2024, with a corresponding weighted-average yield of 2.20 percent. The weighted-average maturity of total available-for-sale investment securities was 6.8 years at December 31, 2024, with a corresponding weighted-average yield of 3.67 percent.
(c)Information related to obligations of state and political subdivisions is presented based upon yield to first optional call date if the security is purchased at a premium, and yield to maturity if the security is purchased at par or a discount.
(d)Maturity calculations for obligations of state and political subdivisions are based on the first optional call date for securities with a fair value above par and the contractual maturity date for securities with a fair value equal to or below par.
(e)Weighted-average yields for obligations of state and political subdivisions are presented on a fully-taxable equivalent basis based on a federal income tax rate of 21 percent.
