Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivatives | 6. Derivatives Risk Management Objective of Using Derivatives The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments. The Bank also enters into interest rate derivative agreements as a service to certain qualifying customers. The Bank manages a matched book with respect to these customer derivatives in order to minimize its net interest rate risk exposure resulting from such agreements. In addition, the Bank also enters into risk participation agreements under which it may either sell or buy credit risk associated with a customer’s performance under certain interest rate derivative contracts related to loans in which participation interests have been sold to or purchased from other banks. Fair Values of Derivative Instruments on the Balance Sheet The table below presents the notional or contractual amounts and fair values of the Company’s derivative financial instruments as well as their classification on the consolidated balance sheets at March 31, 2026 and December 31, 2025.

(1) Derivative assets and liabilities are reported in other assets and other liabilities, respectively, in the consolidated balance sheets. (2) Represents balance sheet netting of derivative assets and liabilities for variation margin collateral held or placed with the same central clearing counterparty. See offsetting assets and liabilities for further information. Cash Flow Hedges of Interest Rate Risk The Company is party to various interest rate swap agreements designated and qualifying as cash flow hedges of the Company’s forecasted variable cash flows for pools of variable rate loans. For each agreement, the Company receives interest at a fixed rate and pays at a variable rate. The Company has terminated certain interest rate swaps designated as cash flow hedges prior to maturity. The net cash received/paid for these transactions was recorded as accumulated other comprehensive income (loss) and is being amortized into earnings through the original maturity dates of the respective contracts. The notional amounts of the active interest rate swap agreements at March 31, 2026 expire as follows: $350 million in 2026; $825 million in 2027; $50 million in 2028; $275 million in 2029 and $300 million in 2030. Fair Value Hedges of Interest Rate Risk Interest rate swaps on securities available for sale The Company is party to forward-starting fixed payer swaps that convert the latter portion of the term of certain available for sale securities to a floating rate. These derivative instruments are designated as fair value hedges of interest rate risk. This strategy provides the Company with a fixed rate coupon during the front-end unhedged tenor of the bonds and results in a floating rate security during the back-end hedged tenor. At March 31, 2026, these single layer instruments have hedge start dates between February 2025 and July 2026, and maturity dates from March 2030 through March 2031. The change in the fair value of the hedged item attributable to interest rate risk and the net hedge income from effective hedges is presented in interest income along with the change in the fair value of the hedging instrument. The notional amount of fair value hedges that are effective totaled $265 million and $125 million at March 31, 2026 and 2025, respectively. Once effective, fair value hedges synthetically convert the notional portion of the hedged asset to a variable rate over the life of the hedge that is indexed to the federal funds effective rate, with the resulting net earnings recorded in interest income on the "Securities-taxable" line item on the Consolidated Statements of Income. The hedged available for sale securities are part of closed portfolios of pre-payable commercial mortgage backed securities. In accordance with ASC 815, prepayment risk may be excluded when measuring the change in fair value of such hedged items attributable to interest rate risk under the portfolio layer method. At March 31, 2026, the amortized cost basis of the closed portfolio of pre-payable commercial mortgage backed securities totaled $387.8 million, excluding any basis adjustment. The amount that represents the hedged items was $335.6 million and the basis adjustment associated with the hedged items was a loss totaling $23.4 million. The Company terminated one swap agreement designated as a fair value hedge during the three months ended March 31, 2026 and received cash received of approximately $1.7 million and also sold the underlying security. There were no fair value swap agreements terminated during the three months ended March 31, 2025. Derivatives Not Designated as Hedges Customer interest rate derivative program The Bank enters into interest rate derivative agreements, primarily rate swaps, with commercial banking customers to facilitate their risk management strategies. The Bank enters into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings. Risk participation agreements The Bank also enters into risk participation agreements under which it may either assume or sell credit risk associated with a borrower’s performance under certain interest rate derivative contracts. In those instances where the Bank has assumed credit risk, it is not a direct counterparty to the derivative contract with the borrower and has entered into the risk participation agreement because it is a party to the related loan agreement with the borrower. In those instances in which the Bank has sold credit risk, it is the sole counterparty to the derivative contract with the borrower and has entered into the risk participation agreement because other banks participate in the related loan agreement. The Bank manages its credit risk under risk participation agreements by monitoring the creditworthiness of the borrower, based on the Bank’s normal credit review process. Mortgage banking derivatives The Bank also enters into certain derivative agreements as part of its mortgage banking activities. These agreements include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell loans to investors on either a best efforts or a mandatory delivery basis. The Company uses these forward sales commitments, which may include To Be Announced (“TBA”) security contracts, on the open market to protect the value of its rate locks and mortgage loans held for sale from changes in interest rates and pricing between the origination of the rate lock and the final sale of these loans. These instruments meet the definition of derivative financial instruments and are reflected in other assets and other liabilities in the Consolidated Balance Sheets, with changes to the fair value recorded in noninterest income within the secondary mortgage market operations line item in the Consolidated Statements of Income. The loans sold on a mandatory basis commit the Company to deliver a specific principal amount of mortgage loans to an investor at a specified price, by a specified date. If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, we may be obligated to pay a pair-off fee, based on then-current market prices, to the investor/counterparty to compensate the investor for the shortfall. Mandatory delivery forward commitments include TBA security contracts on the open market to provide protection against changes in interest rates on the locked mortgage pipeline. The Company expects that mandatory delivery contracts, including TBA security contracts, will experience changes in fair value opposite to the changes in the fair value of derivative loan commitments. Certain assumptions, including pull through rates and rate lock periods, are used in managing the existing and future hedges. The accuracy of underlying assumptions could impact the ultimate effectiveness of any hedging strategies. Forward commitments under best effort contracts commit the Company to deliver a specific individual mortgage loan to an investor if the loan to the underlying borrower closes. Generally, best efforts cash contracts have no pair-off risk regardless of market movement. The price the investor will pay the seller for an individual loan is specified prior to the loan being funded, generally the same day the Company enters into the interest rate lock commitment with the potential borrower. The Company expects that these best efforts forward loan sale commitments will experience a net neutral shift in fair value with related derivative loan commitments. At the closing of the loan, the rate lock commitment derivative expires and the Company generally records a loan held for sale at fair value under the election of fair value option. Customer foreign exchange forward contract derivatives The Company enters into foreign exchange forward derivative agreements, primarily forward foreign currency contracts, with commercial banking customers to facilitate their risk management strategies. The Bank manages its risk exposure from such transactions by entering into offsetting agreements with unrelated financial institutions. The Bank has not elected to designate these foreign exchange forward contract derivatives as hedges; as such, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings. Visa Class B derivative contract The Company is a member of Visa USA. In 2018, the Company sold the majority of its Visa Class B holdings, at which time it entered into a derivative agreement with the purchaser whereby the Company will make or receive cash payments whenever the conversion ratio of the Visa Class B shares into Visa Class A shares is adjusted. The conversion ratio changes when Visa deposits funds to a litigation escrow established by Visa to pay settlements for certain litigation, for which Visa is indemnified by Visa USA members. The Company is also required to make periodic financing payments to the purchaser until all of Visa’s covered litigation matters are resolved. Thus, the derivative contract extends until the end of Visa’s covered litigation matters, the timing of which is uncertain. During the second quarter of 2024, Visa allowed Class B holders to convert some but not all of their Class B shares to Class A shares. As a result of this conversion event, the Bank and its counterparty agreed to modify the transaction agreement to reflect the partial exchange and include certain provisions related to conversion rate changes. The conversion plan approved by Visa requires a minimum of 12 months before another exchange event and thus extends the expected time for a full resolution of the matter. The contract includes a contingent accelerated termination clause based on the credit ratings of the Company. The fair value of the liability associated with this contract was $1.1 million at March 31, 2026 and $1.3 million at December 31, 2025. Refer to Note 15 – Fair Value of Financial Instruments for discussion of the valuation inputs and process for this derivative liability. Effect of Derivative Instruments on the Statements of Income The effects of derivative instruments on the Consolidated Statements of Income for the three months ended March 31, 2026 and 2025 are presented in the table below.

(1) Includes the effects of both active derivative instruments and the impact from realization of basis adjustments to hedged assets resulting from previously terminated hedges. Credit Risk-Related Contingent Features Certain of the Bank’s derivative instruments contain provisions allowing the financial institution counterparty to terminate the contracts in certain circumstances, such as the downgrade of the Bank’s credit ratings below specified levels, a default by the Bank on its indebtedness, or the failure of the Bank to maintain specified minimum regulatory capital ratios or its regulatory status as a well-capitalized institution. These derivative agreements also contain provisions regarding the posting of collateral by each party. At March 31, 2026, the Company was not in violation of any such provisions. The aggregate fair value of derivative instruments with credit risk-related contingent features that were in a net liability position was $13.2 million at both March 31, 2026 and December 31, 2025 for which the Company had posted collateral of $13.6 million and $13.0 million, respectively. Offsetting Assets and Liabilities The Bank’s derivative instruments with certain counterparties contain legally enforceable netting provisions that allow for net settlement of multiple transactions to a single amount, which may be positive, negative, or zero. Agreements with certain bilateral counterparties require both parties to maintain collateral in the event that the fair values of derivative instruments exceed established exposure thresholds. For centrally cleared derivatives, the Company is subject to initial margin posting and daily variation margin exchange with the central clearinghouses. Offsetting information in regards to all derivative assets and liabilities, including accrued interest, subject to these master netting agreements at March 31, 2026 and December 31, 2025 is presented in the following tables.
