Accounting Policies [Abstract] |
Basis of presentation | Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco” or the "Company") have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2024. Wesbanco’s interim financial statements have been prepared following the significant accounting policies disclosed in Note 1 of the Notes to the Consolidated Financial Statements of its 2024 Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC"), as well as with the policy changes indicated below. In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly Wesbanco’s financial position and results of operations for each of the interim periods presented. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on Wesbanco’s net income and shareholders’ equity. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year.
Recent accounting pronouncements | Recent accounting pronouncements—The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below. ASU 2025-07 Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606) In September 2025, the FASB issued ASU 2025-07, “Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606).” The amendments in this Update apply to all entities that enter into non exchange-traded contracts with underlyings based on operations or activities specific to one of the parties to the contract. The amendments in this Update exclude from derivative accounting non exchange-traded contracts with underlyings that are based on operations or activities specific to one of the parties to the contract. However, this scope exception does not apply to (1) variables based on a market rate, market price, or market index, (2) variables based on the price or performance of a financial asset or financial liability of one of the parties to the contract, (3) contracts (or features) involving the issuer’s own equity that are evaluated under the guidance in Subtopic 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity, and (4) call options and put options on debt instruments. The amendments in this Update are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-06 Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40) In September 2025, the FASB issued ASU 2025-06, Goodwill and Other – Internal Use Software (Subtopic 350-40).” The amendments in this Update apply to all entities subject to the internal-use software guidance in Subtopic 350-40. The amendments also apply to all entities that account for website development costs in accordance with Subtopic 350-50, Intangibles—Goodwill and Other—Website Development Costs. The amendments in this Update remove all references to prescriptive and sequential software development stages (referred to as “project stages”) throughout Subtopic 350-40. Therefore, an entity is required to start capitalizing software costs when both of the following occur: (1) management has authorized and committed to funding the software project; (2) it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the “probable-to complete recognition threshold”). The amendments in this Update are effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. This accounting pronouncement is currently not expected to be applicable for Wesbanco. ASU 2025-05 Financial Instruments—Credit Losses (Topic 326) In July 2025, the FASB issued ASU 2025-05, “Financial Instruments – Credit Losses (Topic 326).” The amendments provide (1) all entities with a practical expedient when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606 and (2) entities other than public business entities with an accounting policy election for those same asset classes. The amendments will be effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods in which financial statements have not yet been issued or made available for issuance. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-04 Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606) In May 2025, the FASB issued ASU 2025-04, “Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606).” The amendments in this Update revise the Master Glossary definition of the term performance condition for share-based consideration payable to a customer. The revised definition incorporates conditions (such as vesting conditions) that are based on the volume or monetary amount of a customer’s purchases (or potential purchases) of goods or services from the grantor (including over a specified period of time). Additionally, the amendments in this Update clarify that a grantor should not apply the guidance in Topic 606 on constraining estimates of variable consideration to share-based consideration payable to a customer. The amendments in this Update are effective for all entities for annual reporting periods (including interim reporting periods within annual reporting periods) beginning after December 15, 2026. Early adoption is permitted for all entities. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-03 Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity In May 2025, the FASB issued ASU 2025-03, “Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity.” The amendments in this update require an entity involved in an acquisition transaction effected primarily by exchanging equity interests when the legal acquiree is a variable interest entity ("VIE") that meets the definition of a business to consider the factors in paragraphs 805-10-55-12 through 55-15 to determine which entity is the accounting acquirer. The amendments in this Update differ from current GAAP 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. For Wesbanco, the amendments in this Update are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-01 & 2024-03 – Income Statement — Reporting Comprehensive Income –Expense Disaggregation Disclosures (Subtopic 220-40) In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures.” The amendments in this Update improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. This information is generally not presented in the financial statements today. For Wesbanco, the amendments in this Update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements, but is expected to result in additional disclosures and potential changes to the line items on the Consolidated Statement of Income. In January 2025, the FASB issued ASU 2025-01, “Income Statement — Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40).” The amendment in this Update amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. ASU 2024-04 – Debt—Debt with Conversion and Other Options (Subtopic 470-20) In November 2024, the FASB issued ASU 2024-04, “Debt – Debt with Conversion and Other Options (Subtopic 470-20).” The amendments in this Update clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. Under the amendments, to account for a settlement of a convertible debt instrument as an induced conversion, an inducement offer is required to provide the debt holder with, at a minimum, the consideration (in form and amount) issuable under the conversion privileges provided in the terms of the instrument. For Wesbanco, the amendments in this Update are effective for all entities for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted for all entities that have adopted the amendments in Update 2020-06. The amendments in this Update permit an entity to apply the new guidance on either a prospective or a retrospective basis. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2024-01 – Compensation – Stock Compensation (Topic 718) In March 2024, the FASB issued ASU 2024-01, “Stock Compensation (Topic 718).” The amendments in this Update are designed to improve GAAP by adding an illustrative example that includes four fact patterns to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether a profits interest award should be accounted for in accordance with Topic 718. The illustrative example is intended to reduce (1) complexity in determining whether a profits interest award is subject to the guidance in Topic 718 and (2) existing diversity in practice. For Wesbanco, the amendments are effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. If an entity adopts the amendments in an interim period, it should adopt them as of the beginning of the annual period that includes that interim period. This accounting pronouncement is currently not applicable for Wesbanco. ASU 2023-09 – Income Taxes (Topic 740): Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740)." The amendments in this Update related to the rate reconciliation and income taxes paid disclosures and are designed to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. For Wesbanco, the amendments are effective for annual periods beginning after December 15, 2024. Early adopt ion is permitted for annual financial statements that have not yet been issued or made available for issuance. The adoption of this pronouncement is no t expected to have a material impact on the Consolidated Financial Statements but will result in additional disclosures within the Notes to the Consolidated Financial Statements. ASU 2023-07—Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures In November 2023, the FASB issued ASU 2023-07, “Improvements to Reportable Segment Disclosures (Topic 280).” The amendments in this Update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. The amendments in this Update do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adopt ion is permitted. The adoption of this pronouncement did not have a material impact on the Consolidated Financial Statements but has resulted in additional disclosures within the Notes to the Consolidated Financial Statements related to segment reporting. Please refer to Footnote 14, "Business Segments" for additional information. ASU 2023-06 - Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative In October 2023, the FASB issued ASU 2023-06, "Disclosure Improvements." For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on 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. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2023-05 – Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement In August 2023, the FASB issued ASU 2023-05, "Business Combinations - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement," under which an entity that qualifies as either a joint venture or a corporate joint venture as defined in the FASB Accounting Standards Codification ("ASC") master glossary is required to apply a new basis of accounting upon the formation of the joint venture. Specifically, the ASU provides that a joint venture or a corporate joint venture (collectively, “joint ventures”) must initially measure its assets and liabilities at fair value on the formation date. For Wesbanco, the amendments are effective for all joint ventures within the ASU’s scope that are formed on or after January 1, 2025. Early adoption is permitted in any annual or interim period as of the beginning of the related fiscal year. This accounting pronouncement is currently not applicable for Wesbanco.
