Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) as set forth by the Financial Accounting Standards Board (“FASB”) and its Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) as well as the rules and interpretive releases of the U.S. Securities and Exchange Commission (“SEC”) under the authority of federal securities laws. The Consolidated Financial Statements include the accounts of the Company, its wholly-owned subsidiaries and entities in which it holds a controlling financial interest through being the primary beneficiary or through holding a majority of the voting interest. All intercompany accounts and transactions have been eliminated in consolidation. Certain previously reported amounts have been reclassified to conform to the current period’s presentation which includes: •reclassification of certain mortgage banking income accounts previously included in “(losses) gains on mortgage loans held for sale, net” and in “other noninterest income” to a new financial statement line item titled “mortgage banking income (loss).” •combination of certain non-operating income accounts previously included in “other noninterest income” into a new financial statement line item titled “other non-operating loss.” The accompanying Consolidated Balance Sheet as of March 31, 2026, the Consolidated Statements of Income and Comprehensive Income and of Changes in Shareholders’ Equity for the three months ended March 31, 2026 and 2025 and Statements of Cash Flows for the three months ended March 31, 2026 and 2025 are unaudited. The Consolidated Balance Sheet as of December 31, 2025 was derived from the Audited Consolidated Financial Statements as of that date. The interim Consolidated Financial Statements and the accompanying notes should be read in conjunction with the annual Consolidated Financial Statements and the accompanying notes contained within the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (“2025 Form 10-K”), as filed with the SEC. In the opinion of management, the Company’s Consolidated Financial Statements reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The results for the three months ended March 31, 2026 are not necessarily indicative of results to be expected for the year ending December 31, 2026, any other interim period, or any future year or period.
Use of Estimates	Use of Estimates In preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, valuation and fair value measurements, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Relevant standards that were recently issued but not yet adopted as of March 31, 2026: In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements–Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”). The amendments in this update modify the disclosure or presentation requirements for a variety of topics in the codification. Certain amendments represent clarifications to or technical corrections of the current requirements. The following is a summary of the topics included in the update and which pertain to the Company: 1.Statement of cash flows (Topic 230): Requires an accounting policy disclosure in annual periods of where cash flows associated with derivative instruments and their related gains and loses are presented in the statement of cash flows; 2.Accounting changes and error corrections (Topic 250): Requires that when there has been a change in the reporting entity, the entity disclose any material prior-period adjustment and the effect of the adjustment on retained earnings in interim financial statements; 3.Earnings per share (Topic 260): Requires disclosure of the methods used in the diluted earnings-per-share computation for each dilutive security and clarifies that certain disclosures should be made during interim periods, and amends illustrative guidance to illustrate disclosure of the methods used in the diluted earnings per share computation; 4.Commitments (Topic 440): Requires disclosure of assets mortgaged, pledged, or otherwise subject to lien and the obligations collateralized; and 5.Debt (Topic 470): Requires disclosure of amounts and terms of unused lines of credit and unfunded commitments and the weighted-average interest rate on outstanding short-term borrowings. For public business entities, the amendments in ASU 2023-06 are effective on the date which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the codification and will not become effective for any entity. Early adoption is not permitted and the amendments are required to be applied on a prospective basis. The Company does not expect the adoption of this standard will have a material impact on its Consolidated Financial Statements. In November 2024, the FASB issued ASU 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40). The amendments in this update require disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity: 1.Disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)–(e). 2.Include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements. 3.Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. 4.Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. For public business entities, the amendments in ASU 2024-03 are effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this update are to be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this update or (2) retrospectively to any or all prior periods presented in the financial statements. The Company expects the adoption of this standard will not have a material impact on its Consolidated Financial Statements. In April 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer of a Variable Interest Entity. The amendments in this update are intended to improve the requirements for identifying the accounting acquirer in Topic 805, Business Combinations. The amendments in this update differ from current generally accepted accounting principles because, for certain transactions, they replace the requirement that the primary beneficiary always is the acquirer with an assessment that requires an entity to consider the factors to determine which entity is the accounting acquirer. The amendments in this update enhance the comparability of financial statements across entities engaging in acquisition transactions effected primarily by exchanging equity interests when the legal acquiree meets the definition of a business. Specifically, under the amendments, acquisition transactions in which the legal acquiree is a variable interest entity will, in more instances, result in the same accounting outcomes as economically similar transactions in which the legal acquiree is a voting interest entity. The amendments in this update do not change the accounting for a transaction determined to be a reverse acquisition or a transaction in which the legal acquirer is not a business and is determined to be the accounting acquiree. For public business entities, the amendments in ASU 2025-03 are effective for annual periods beginning after December 15, 2026 and interim periods within those annual periods. Adoption should be done on a prospective basis. Early adoption is permitted as of the beginning of an interim or annual reporting period. The Company does not expect the adoption of this standard will have a material impact on its Consolidated Financial Statements. In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements. The amendments in this update help clarify and refine hedge accounting requirements, including clarifications to documentation and designation in regards to hedge relationships. The update introduces improvements to hedge accounting to better align financial reporting with the economic results of an entity's risk management activities. Early adoption is permitted. For public business entites, the amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim periods within those annual reporting periods. The Company does not expect the adoption of this standard to have a material impact on its Consolidated Financial Statements. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The amendments in this update clarify interim disclosure requirements and the applicability of Topic 270. The amendments in this update result in a comprehensive list of interim disclosures that are required by GAAP. In developing the list of disclosures required by other Topics, the Board focused on identifying the interim disclosures that are currently required under GAAP. The objective of the amendments is to provide clarity about the current requirements, rather than evaluate whether to expand or reduce interim disclosure requirements. The amendments in this update also include a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The intent of the disclosure principle, which is modeled after a previous SEC disclosure requirement, is to help entities determine whether disclosures not specified in Topic 270 should be provided in interim reporting periods. The amendments in this update also clarify the applicability of Topic 270, the types of interim reporting, and the form and content of interim financial statements in accordance with GAAP. For public business entities, the amendments in ASU 2025-11 are effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. Adoption can be applied either prospectively or retrospectively to any or all prior periods presented in the financial statements. Early adoption is permitted. The Company does not expect the adoption of this standard will have a material impact on its Consolidated Financial Statements. No standards were adopted during the three months ended March 31, 2026
