Accounting Policies [Abstract]
Basis of presentation	Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco”) 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, 2022. 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 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission, 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.
Modifications for Borrowers Experiencing Financial Difficulty ("MBEFD")	Modifications for Borrowers Experiencing Financial Difficulty (“MBEFD”) — A modification of a loan for borrowers experiencing financial difficulty is applicable when the loan modification results in a direct change in the timing or amount of contractual cash flows. The most common modifications provided to borrowers experiencing financial difficulty are expected to occur in the form of principal forgiveness, interest rate reductions, other-than-insignificant-payment delays, or term extensions under ASC 310-10-50-39. Upon Wesbanco's adoption of Accounting Standards Update (“ASU”) 2022-02 on January 1, 2023, Troubled Debt Restructuring ("TDR") accounting was prospectively discontinued and economic concessions for modifications occurring on or after the adoption date are no longer measured. This accounting also results in the elimination of any existing economic concession related to a loan that was previously designated as a TDR if such loan is restructured on or after January 1, 2023. Due to the elimination of economic concessions under ASU 2022-02, the standard may result in modified loans being subject to the new disclosures that would have not been considered concessions and not treated as TDRs. When determining whether a debtor is experiencing financial difficulties, consideration is given to any known default on any of its debt or whether it is probable that the debtor would be in payment default in the foreseeable future without the modification. Other indicators of financial difficulty include whether the debtor has declared or is in the process of declaring bankruptcy, the debtor’s ability to continue as a going concern, or the debtor’s projected cash flow to service its debt (including principal & interest) in accordance with the contractual terms for the foreseeable future, without a modification. If the payment of principal at original maturity is primarily dependent on the value of collateral, the current value of that collateral is considered in determining whether the principal will be paid. The modification of a loan does not increase the allowance or provision for credit losses unless the loan is extended, or the loans are commercial loans that are individually evaluated for impairment, in which case a specific reserve is established pursuant to GAAP. Portfolio segment loss history is the primary factor for establishing the allowance for residential real estate, home equity and consumer MBEFDs. Non-accrual loans that are restructured remain on non-accrual, but may move to accrual status after they have performed according to the restructured terms for a period of time. MBEFDs on accrual status generally remain on accrual as long as they continue to perform in accordance with their modified terms. MBEFDs may also be placed on non-accrual if they do not perform in accordance with the restructured terms. Loans may be removed from MBEFD status after they have performed according to the renegotiated terms for a period of time.
Recent accounting pronouncements	Recent accounting pronouncements—The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below. 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. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2023-04 - Liabilities (Topic 405): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 121 (SEC Update) In August 2023, the FASB issued ASU 2023-04, "Liabilities (Topic 405): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No.121." ASU 2023-04 adds various SEC paragraphs to the Codification to reflect guidance included in SEC Staff Accounting Bulletin No. 121 on safeguarding crypto assets. As no new guidance is provided, there is no transition or effective date associated with this update. ASU 2023-03 - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120 In July 2023, FASB issued ASU 2023-03, which amends or supersedes various SEC paragraphs within the Codification to conform to past SEC announcements and guidance issued by the SEC. The ASU does not provide any new guidance. Therefore, there is no transition or effective date associated with this update. ASU 2023-02 – Investments Equity Method and Joint Ventures (Topic 323) In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The ASU’s amendments “remove the specialized guidance for [low-income-housing tax credit] investments that are not accounted for using the proportional amortization method and instead require that those LIHTC investments be accounted for using the guidance in other [GAAP].” For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2023-01 - Leases (Topic 842): Common Control Arrangements In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements. ASU 2023-01 amends certain provisions of ASC 842 that apply to arrangements between related parties under common control. Additionally, ASU 2023-01 amends the accounting for leasehold improvements in common-control arrangements for all entities. For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted in any annual or interim period as of the beginning of the related fiscal year. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2022-04 - Liabilities – Supplier Finance Programs (Sub-topic 405-50) In September 2022, the FASB issued ASU 2022-04, “Liabilities—Supplier Finance Programs (Subtopic 405-50).” The amendments in this ASU require that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. To achieve that objective, the buyer should disclose qualitative and quantitative information about its supplier finance programs. For Wesbanco, this update was effective beginning on January 1, 2023, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. The adoption of this full pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2022-03 - Fair Value Measurement (Topic 820) In June 2022, the FASB issued ASU 2022-03, "Fair Value Measurement (Topic 820).” The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. Furthermore, the amendments to this ASU clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The update to this ASU requires the following disclosures for equity securities: (1) the fair value of equity securities subject to contractual sale restrictions reflected in the balance sheet; (2) the nature and remaining duration of the restriction(s) and; (3) the circumstances that could cause a lapse in the restriction(s). The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Wesbanco is currently assessing the impact of ASU 2022-03 on its Consolidated Financial Statements. ASU 2022-02 - Financial Instruments - Credit Losses (Topic 326) In March 2022, the FASB issued ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326)." The amendments in this ASU eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, "Receivables - Troubled Debt Restructurings by Creditors," while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, for public business entities, the amendments in this Update require that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, "Financial Instruments - Credit Losses - Measured at Amortized Cost." For Wesbanco, this update was effective beginning on January 1, 2023. The adoption of this pronouncement did not have a material impact on the Consolidated Financial Statements. For the additional disclosure requirements in this ASU, please refer to the MBEFD policy above and Note 4, "Loans and the Allowance for Credit Losses." ASU 2020-04, ASU 2021-01 and ASU 2022-06 - Reference Rate Reform (Topic 848) In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848).” This ASU provided temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the London Interbank Offered Rate ("LIBOR") or other reference rate expected to be discontinued on financial reporting. The ASU also provides optional expedients for contract modifications that replace a reference rate affected by reference rate reform. The guidance is effective as of March 12, 2020 through December 31, 2022, and can be adopted at any time during this period. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” This ASU refines the scope of Topic 848 and addresses questions about whether Topic 848 can be applied to derivative instruments that do not reference a rate that is expected to be discontinued, but that use an interest rate for margining, discounting or contract price alignment that is expected to be modified as a result of reference rate reform. ASU 2021-01 is effective upon issuance through December 31, 2024, and can be adopted at any time during this period. Wesbanco has not offered LIBOR for any new contracts after December 31, 2021. Wesbanco has chosen the One Month Term Secured Overnight Financing Rate ("1M Term SOFR") as its alternative replacement rate for LIBOR on both back-to-back swaps and on one-month variable loans. A transition plan was implemented in 2021 to identify and modify Wesbanco's loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” In the Update, the Board decided to defer the sunset date of Topic 848 to December 31, 2024, to permit entities to apply the guidance in Topic 848 through the expected cessation date of USD LIBOR. In the Board’s view, that time frame would have been sufficient to provide flexibility for additional unforeseen changes to the timeline of USD LIBOR cessation and to accommodate global interbank offered rate (IBOR) transition. The update did not have a material impact on Wesbanco’s Consolidated Financial Statements.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2023

Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco”) 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, 2022.

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 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission, 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.

Modifications for Borrowers Experiencing Financial Difficulty ("MBEFD")

Modifications for Borrowers Experiencing Financial Difficulty (“MBEFD”) — A modification of a loan for borrowers experiencing financial difficulty is applicable when the loan modification results in a direct change in the timing or amount of contractual cash flows. The most common modifications provided to borrowers experiencing financial difficulty are expected to occur in the form of principal forgiveness, interest rate reductions, other-than-insignificant-payment delays, or term extensions under ASC 310-10-50-39. Upon Wesbanco's adoption of Accounting Standards Update (“ASU”) 2022-02 on January 1, 2023, Troubled Debt Restructuring ("TDR") accounting was prospectively discontinued and economic concessions for modifications occurring on or after the adoption date are no longer measured. This accounting also results in the elimination of any existing economic concession related to a loan that was previously designated as a TDR if such loan is restructured on or after January 1, 2023. Due to the elimination of economic concessions under ASU 2022-02, the standard may result in modified loans being subject to the new disclosures that would have not been considered concessions and not treated as TDRs.

When determining whether a debtor is experiencing financial difficulties, consideration is given to any known default on any of its debt or whether it is probable that the debtor would be in payment default in the foreseeable future without the modification. Other indicators of financial difficulty include whether the debtor has declared or is in the process of declaring bankruptcy, the debtor’s ability to continue as a going concern, or the debtor’s projected cash flow to service its debt (including principal & interest) in accordance with the contractual terms for the foreseeable future, without a modification. If the payment of principal at original maturity is primarily dependent on the value of collateral, the current value of that collateral is considered in determining whether the principal will be paid.

The modification of a loan does not increase the allowance or provision for credit losses unless the loan is extended, or the loans are commercial loans that are individually evaluated for impairment, in which case a specific reserve is established pursuant to GAAP. Portfolio segment loss history is the primary factor for establishing the allowance for residential real estate, home equity and consumer MBEFDs.

Non-accrual loans that are restructured remain on non-accrual, but may move to accrual status after they have performed according to the restructured terms for a period of time. MBEFDs on accrual status generally remain on accrual as long as they continue to perform in accordance with their modified terms. MBEFDs may also be placed on non-accrual if they do not perform in accordance with the restructured terms. Loans may be removed from MBEFD status after they have performed according to the renegotiated terms for a period of time.

Recent accounting pronouncements

Recent accounting pronouncements—The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below.

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. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

In August 2023, the FASB issued ASU 2023-04, "Liabilities (Topic 405): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No.121." ASU 2023-04 adds various SEC paragraphs to the Codification to reflect guidance included in SEC Staff Accounting Bulletin No. 121 on safeguarding crypto assets. As no new guidance is provided, there is no transition or effective date associated with this update.

ASU 2023-03 - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120

In July 2023, FASB issued ASU 2023-03, which amends or supersedes various SEC paragraphs within the Codification to conform to past SEC announcements and guidance issued by the SEC. The ASU does not provide any new guidance. Therefore, there is no transition or effective date associated with this update.

ASU 2023-02 – Investments Equity Method and Joint Ventures (Topic 323)

In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The ASU’s amendments “remove the specialized guidance for [low-income-housing tax credit] investments that are not accounted for using the proportional amortization method and instead require that those LIHTC investments be accounted for using the guidance in other [GAAP].” For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2023-01 - Leases (Topic 842): Common Control Arrangements

In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements. ASU 2023-01 amends certain provisions of ASC 842 that apply to arrangements between related parties under common control. Additionally, ASU 2023-01 amends the accounting for leasehold improvements in common-control arrangements for all entities. For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted in any annual or interim period as of the beginning of the related fiscal year. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2022-04 - Liabilities – Supplier Finance Programs (Sub-topic 405-50)

In September 2022, the FASB issued ASU 2022-04, “Liabilities—Supplier Finance Programs (Subtopic 405-50).” The amendments in this ASU require that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. To achieve that objective, the buyer should disclose qualitative and quantitative information about its supplier finance programs. For Wesbanco, this update was effective beginning on January 1, 2023, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. The adoption of this full pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2022-03 - Fair Value Measurement (Topic 820)

In June 2022, the FASB issued ASU 2022-03, "Fair Value Measurement (Topic 820).” The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. Furthermore, the amendments to this ASU clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The update to this ASU requires the following disclosures for equity securities: (1) the fair value of equity securities subject to contractual sale restrictions reflected in the balance sheet; (2) the nature and remaining duration of the restriction(s) and; (3) the circumstances that could cause a lapse in the restriction(s). The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Wesbanco is currently assessing the impact of ASU 2022-03 on its Consolidated Financial Statements.

ASU 2022-02 - Financial Instruments - Credit Losses (Topic 326)

In March 2022, the FASB issued ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326)." The amendments in this ASU eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, "Receivables - Troubled Debt Restructurings by Creditors," while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, for public business entities, the amendments in this Update require that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, "Financial Instruments - Credit Losses - Measured at Amortized Cost." For Wesbanco, this update was effective beginning on January 1, 2023. The adoption of this pronouncement did not have a material impact on the Consolidated Financial Statements. For the additional disclosure requirements in this ASU, please refer to the MBEFD policy above and Note 4, "Loans and the Allowance for Credit Losses."

ASU 2020-04, ASU 2021-01 and ASU 2022-06 - Reference Rate Reform (Topic 848)

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848).” This ASU provided temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the London Interbank Offered Rate ("LIBOR") or other reference rate expected to be discontinued on financial reporting. The ASU also provides optional expedients for contract modifications that replace a reference rate affected by reference rate reform. The guidance is effective as of March 12, 2020 through December 31, 2022, and can be adopted at any

time during this period. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” This ASU refines the scope of Topic 848 and addresses questions about whether Topic 848 can be applied to derivative instruments that do not reference a rate that is expected to be discontinued, but that use an interest rate for margining, discounting or contract price alignment that is expected to be modified as a result of reference rate reform. ASU 2021-01 is effective upon issuance through December 31, 2024, and can be adopted at any time during this period. Wesbanco has not offered LIBOR for any new contracts after December 31, 2021. Wesbanco has chosen the One Month Term Secured Overnight Financing Rate ("1M Term SOFR") as its alternative replacement rate for LIBOR on both back-to-back swaps and on one-month variable loans. A transition plan was implemented in 2021 to identify and modify Wesbanco's loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” In the Update, the Board decided to defer the sunset date of Topic 848 to December 31, 2024, to permit entities to apply the guidance in Topic 848 through the expected cessation date of USD LIBOR. In the Board’s view, that time frame would have been sufficient to provide flexibility for additional unforeseen changes to the timeline of USD LIBOR cessation and to accommodate global interbank offered rate (IBOR) transition. The update did not have a material impact on Wesbanco’s Consolidated Financial Statements.
