| Fair Value Measurements |
Fair Value Measurements Fair value represents the estimated price at which an orderly transaction to sell an asset or to transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept). The valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis are described in the Fair Value Measurements note in the Corporation’s 2025 Annual Report on Form 10-K, as well as Note 3 Business Combinations. The tables below present the Corporation’s financial instruments measured at fair value on a recurring basis and carrying amounts and estimated fair values of certain financial instruments, aggregated by the level in the fair value hierarchy within which those measurements fall: | | | | | | | | | | | | | | | | | | | Sep 30, 2026 | | (in thousands) | Carrying Amount | Fair Value | Level 1 | Level 2 | Level 3 | | Assets | | | | | | | Cash and due from banks | $ | 644,519 | | $ | 644,519 | | $ | 644,519 | | $ | — | | $ | — | | | Interest-bearing deposits in other financial institutions | 982,850 | | 982,850 | | 982,850 | | — | | — | | | Federal funds sold and securities purchased under agreements to resell | 100 | | 100 | | 100 | | — | | — | | | AFS investment securities: | | | | | | | | | | | | | | | | | | | Obligations of state and political subdivisions (municipal securities) | 6,392 | | 6,392 | | — | | 6,392 | | — | | | Residential mortgage-related securities: | | | | | | | FNMA / FHLMC | 134,464 | | 134,464 | | — | | 134,464 | | — | | | GNMA | 5,352,106 | | 5,352,106 | | — | | 5,352,106 | | — | | | | | | | | | Commercial mortgage-related securities: | | | | | | | FNMA / FHLMC | 347,399 | | 347,399 | | — | | 347,399 | | — | | | GNMA | 102,863 | | 102,863 | | — | | 102,863 | | — | | | Asset backed securities: | | | | | | | FFELP | 86,048 | | 86,048 | | — | | 86,048 | | — | | | SBA | 164,502 | | 164,502 | | — | | 164,502 | | — | | Other debt securities(a) | 5,054 | | 5,054 | | — | | 2,991 | | 2,063 | | | Total AFS investment securities | 6,198,828 | | 6,198,828 | | — | | 6,196,765 | | 2,063 | | | | | | | | | HTM investment securities: | | | | | | | U.S. Treasury securities | 997 | | 993 | | 993 | | — | | — | | | Obligations of state and political subdivisions (municipal securities) | 1,576,827 | | 1,304,761 | | — | | 1,304,761 | | — | | | Residential mortgage-related securities: | | | | | | | FNMA / FHLMC | 771,047 | | 598,700 | | — | | 598,700 | | — | | | GNMA | 36,181 | | 31,634 | | — | | 31,634 | | — | | | Private-label | 284,928 | | 224,916 | | — | | 224,916 | | — | | | Commercial mortgage-related securities: | | | | | | | FNMA / FHLMC | 752,924 | | 609,904 | | — | | 609,904 | | — | | | GNMA | 39,316 | | 33,974 | | — | | 33,974 | | — | | | Total HTM investment securities | 3,462,220 | | 2,804,882 | | 993 | | 2,803,889 | | — | | | | | | | | | Equity securities: | | | | | | | Equity securities | 15,043 | | 15,043 | | 15,043 | | — | | — | | | Equity securities at NAV | 15,000 | | 15,000 | | | | | | Total equity securities | 30,043 | | 30,043 | | | | | | | | | | | | Regulatory stocks | 304,330 | | 304,330 | | — | | 304,330 | | — | | | Residential loans held for sale | 66,770 | | 66,770 | | — | | 66,770 | | — | | | | | | | | | Loans, net | 36,005,495 | | 34,759,951 | | — | | — | | 34,759,951 | | | Bank and corporate owned life insurance | 717,175 | | 717,175 | | — | | 717,175 | | — | | | Mortgage servicing rights, net | 94,919 | | 94,919 | | — | | — | | 94,919 | | Interest rate-related instruments designated as hedging instruments(b) | 308 | | 308 | | — | | 308 | | — | | Foreign currency exchange forwards designated as hedging instruments(b) | 2,240 | | 2,240 | | — | | 2,240 | | — | | Interest rate-related and other instruments not designated as hedging instruments(b) | 112,606 | | 112,606 | | — | | 112,606 | | — | | Foreign currency exchange forwards not designated as hedging instruments(b) | 451 | | 451 | | — | | 451 | | — | | | Interest rate lock commitments to originate residential mortgage loans held for sale | 2,931 | | 2,931 | | — | | — | | 2,931 | | | | | | | | | Total selected assets at fair value | $ | 48,625,785 | | $ | 46,722,903 | | $ | 1,643,505 | | $ | 10,204,534 | | $ | 34,859,864 | |

See Note 12 for additional information on the standby letters of credit and for information on the fair value of lending-related commitments. (b) Figures are presented gross before netting. See Note 10 and Note 11 for information relating to the impact of offsetting derivative assets and liabilities and cash collateral with the same counterparty where there is a legally enforceable master netting agreement in place. The table below presents a rollforward of the consolidated balance sheets amounts for the Corporation's mortgage derivatives measured at fair value on a recurring basis and classified within Level 3 of the fair value hierarchy: | | | | | | | | | | | (in thousands) | Interest rate lock commitments to originate residential mortgage loans held for sale | Forward commitments to sell residential mortgage loans | | | Balance December 31, 2024 | $ | 327 | | $ | (254) | | | | New production | 13,435 | | (3,998) | | | | Closed loans / settlements | (13,690) | | 2,738 | | | | Other | 742 | | 1,958 | | | | Change in mortgage derivative | 487 | | 698 | | | | | | | | Balance December 31, 2025 | 814 | | 444 | | | | New production | 11,173 | | (158) | | | | Closed loans / settlements | (8,815) | | 4,843 | | | | Other | (241) | | (5,129) | | | | Change in mortgage derivative | 2,117 | | (444) | | | | | | | | Balance September 30, 2026 | $ | 2,931 | | $ | — | | |
Refer to Note 8 for a rollforward of the consolidated balance sheets amounts for the Corporation's mortgage servicing rights measured at fair value on a recurring basis and classified within Level 3 of the fair value hierarchy. The following table presents a rollforward of the fair value of Level 3 equity securities that are measured under the measurement alternative, and the related adjustments recorded during the periods presented for those securities with observable price changes: | | | | | | | (in thousands) | | | Fair value as of December 31, 2024 | $ | 72 | | | | | | | Purchases | 14 | | | Sales | (23) | | | Transfers out of level 3 | (63) | | | | | Fair value as of December 31, 2025 | $ | — | | | | | | | | | | | | | | | | | | | |
The Corporation did not have any activity for Level 3 equity securities for the nine months ended September 30, 2026. The Corporation acquired a Level 3 AFS debt security upon the acquisition of American National on April 1, 2026. The security was valued at $2.1 million and no related adjustments to fair value have been recorded as of September 30, 2026. The table below presents the Corporation’s assets measured at fair value on a nonrecurring basis, aggregated by the level in the fair value hierarchy within which those measurements fall: | | | | | | | | | | | | | | | | Fair Value | | | | (in thousands) | Fair Value Hierarchy | September 30, 2026 | December 31, 2025 | | | | Assets | | | | | | | | | | | | | Individually evaluated loans | Level 3 | $ | 69,679 | | $ | 18,659 | | | | OREO(a) | Level 2 | 1,442 | | 770 | | | | | | | | | | | | | | | |
(a) These assets are held at lower of its carrying amount or fair value less cost to sell. Assets included here are those that were adjusted to fair value less cost to sell during the period. The table below presents the unobservable inputs that are readily quantifiable pertaining to Level 3 measurements: | | | | | | | | | | | | | | | | | | | | | | September 30, 2026 | Valuation Technique | Significant Unobservable Input | Range of Inputs | Weighted Average Input Applied | | Mortgage servicing rights | Discounted cash flow | Option adjusted spread | 5% | - | 8% | 5% | | Mortgage servicing rights | Discounted cash flow | Constant prepayment rate | 2% | - | 100% | 8% | | | | | | | | | Individually evaluated loans | Discounted cash flow | Discount factor | 30% | - | 45% | 32% | | Individually evaluated loans | Market approach | Appraisal / Cost to sell | 41% | - | 80% | 49% | | Interest rate lock commitments to originate residential mortgage loans held for sale | Discounted cash flow | Closing ratio | 58% | - | 100% | 92% |
