Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NO TE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations— Wesbanco, Inc. (“Wesbanco” or the “Company”) is a bank holding company offering a full range of financial services, including trust and investment services, mortgage banking, insurance and brokerage services. Wesbanco’s defined business segments are community banking and trust and investment services. As of December 31, 2022, Wesbanco’s banking subsidiary, Wesbanco Bank, Inc. (“Wesbanco Bank” or the “Bank”), headquartered in Wheeling, West Virginia, operates throu gh 194 branches and 188 ATM machines in West Virginia, Ohio, western Pennsylvania, Kentucky, southern Indiana and Maryland. In addition, Wesbanco operates an insurance brokerage company, Wesbanco Insurance Services, Inc., and a full service broker/dealer, Wesbanco Securities, Inc. Use of Estimates— The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Principles of Consolidation— The Consolidated Financial Statements include the accounts of Wesbanco and those entities in which Wesbanco has a controlling financial interest. All intercompany balances and transactions have been eliminated in consolidation. Wesbanco determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity. A voting interest entity is an entity in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make financial and operating decisions. Wesbanco consolidates voting interest entities in which it owns all, or at least a majority (generally, greater than 50 %) of the voting interest. Variable interest entities (“VIE”) are entities that in general either do not have equity investors with voting rights or that have equity investors that do not provide sufficient financial resources for the entity to support its activities. Wesbanco uses VIEs in various legal forms to conduct normal business activities. Wesbanco reviews the structure and activities of VIEs for possible consolidation. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits of the VIE that could potentially be significant to the VIE. A VIE often holds financial assets, including loans or receivables, real estate or other property. The company with a controlling financial interest, known as the primary beneficiary, is required to consolidate the VIE. Wesbanco has eleven wholly-owned trust subsidiaries (collectively, the “Trusts”), for which it does not have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance nor the obligation to absorb losses or the right to receive a benefits from the VIE that could be potentially significant to the VIE. Accordingly, the Trusts and their net assets are not included in the Consolidated Financial Statements. However, the junior subordinated deferrable interest debentures issued by Wesbanco to the Trusts (refer to Note 10, “Subordinated Debt and Junior Subordinated Debt”) and the common stock issued by the Trusts is included in the Consolidated Balance Sheets. Wesbanco also owns non-controlling variable interests in certain limited partnerships for which it does not have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance nor the obligation to absorb losses or the right to receive a benefit from the VIE that could be potentially significant to the VIE. These VIEs are not consolidated into Wesbanco’s financial statements because Wesbanco is not considered the primary beneficiary. These investments are accounted for using the equity method of accounting and are included in other assets in the Consolidated Balance Sheets. Refer to Note 7, “Investments in Limited Partnerships” for further detail. Business Combinations— Business combinations are accounted for by applying the acquisition method. As of acquisition date, the identifiable assets acquired and liabilities assumed are measured at fair value and recognized separately from goodwill. Results of operations of the acquired entities are included in the consolidated statement of income from the date of acquisition. Revenue Recognition— Interest income, net securities gains (losses) and bank-owned life insurance are not in scope of ASC 606, Revenue from Contracts with Customers . For the revenue streams in scope of ASC 606 - trust fees, service charges on deposits, net securities brokerage revenue, debit card sponsorship income, payment processing fees, electronic banking fees, mortgage banking income and net gain or loss on sale of other real estate owned and other assets– there are no significant judgements related to the amount and timing of revenue recognition. Trust fees: Fees are earned over a period of time between monthly and annually, per the related fee schedule. The fees are earned ratably over the period for investment, safekeeping and other services performed by Wesbanco. The fees are accrued when earned based on the daily asset value on the last day of the quarter. In most cases, the fees are directly debited from the customer account. WesMark fees consist of investment advisory fees and shareholder service fees and are paid to Wesbanco by the WesMark mutual funds on a monthly basis for Wesbanco’s involvement with the management of the funds. Service charges on deposits: There are monthly service charges for both commercial and personal banking customers, which are earned over the month per the related fee schedule based on the customers’ deposits. There are also transaction-based fees, which are earned based on specific transactions or customer activity within the customers’ deposit accounts. These are earned at the time the transaction or customer activity occurs. The fees are debited from the customer account. Net securities brokerage revenue: Commission income is earned based on customer transactions and management of investments. The commission income from customers’ transactions is recognized when the transaction is complete and approved. Annuity commissions are earned based upon the carrier’s commission rate for the annuity product chosen by the investing customer. The commission income from the management of investments over time is earned continuously over a quarterly period. Debit card sponsorship income: The activity in this revenue stream concluded on March 31, 2021, with the sale of this program to another bank. Debit card sponsorship income was earned from Wesbanco’s sponsorship of its customers, which included independent service organizations, processors and other banks into different debit networks. For providing this service, the customers paid the bank a per transaction fee for each transaction processed through the network. In some cases, customers were also charged annual sponsorship fees and non-compliance fees as applicable. The fees were earned at the time the transaction or customer activity occurred. The fees were either directly debited from the customers' deposit accounts or were billed to the customer. Payment processing fees: Payment processing fees are earned from the bill payment and electronic funds transfer (“EFT”) services provided under the name FirstNet. The fees are derived from both the individual consumer banking transactions and from businesses or service providers through monthly billing for total transactions occurring. These fees are earned at the time the transaction or customer activity occurs. The fees are debited from the customers’ deposit accounts or charged directly to the business or service provider. Electronic banking fees: Interchange and ATM fees are earned based on customer and ATM transactions. Revenue is recognized when the transaction is settled. Mortgage banking income: Income is earned when Wesbanco-originated loans are sold to an investor on the secondary market. The investor bids on the loans. If the price is accepted, Wesbanco delivers the loan documents to the investor. Once received and approved by the investor, revenue is recognized and the loans are derecognized from the Consolidated Balance Sheet. Prior to the loans being sold, they are classified as loans held for sale. Additionally, the changes in the fair value of the loans held for sale, loan commitments and related derivatives are included in mortgage banking income and are somewhat offset by any deferred direct origination costs, such as mortgage loan officer commissions. Net gain or loss on sale of other real estate owned and other assets: Net gain or loss on other real estate owned is recorded when the property is sold to a third party and the Bank collects substantially all of the consideration to which it is entitled in exchange for the transfer of the property. Net gain or loss on other assets can include, among other things, the sale of fixed assets, the change in fair value of the underlying investments funded by Wesbanco’s Community Development Corporation (“Wesbanco CDC”) and residual income earned from the sale of Wesbanco’s debit card sponsorship program. Gains or losses are recognized upon receipt of consideration and subsequent transfer of the property for fixed asset sales. The change in fair value of Wesbanco CDC investments occurs upon the change in the underlying investments as these are accounted for utilizing the equity method, and as such, are not within the scope of ASC 606. Residual income from the sale of the debit card sponsorship program is recognized over time as per the signed agreement between Wesbanco and the buyer. Cash and Cash Equivalents— Cash and cash equivalents include cash and due from banks, due from banks – interest bearing and federal funds sold. Generally, federal funds are sold for one-day periods. Securities— Equity securities: Equity securities, which include investments in various mutual funds held in grantor trusts formed in connection with the Company’s deferred compensation plan, are reported at fair value with the gains and losses included in non-interest income. Available-for-sale debt securities: Debt securities not classified as held-to-maturity are classified as available-for-sale. These securities may be sold at any time based upon management’s assessment of changes in economic or financial market conditions, interest rate or prepayment risks, liquidity considerations and other factors. These securities are stated at fair value, with the fair value adjustment, net of tax, reported as a separate component of accumulated other comprehensive income. Held-to-maturity debt securities: Securities that are purchased with the positive intent and ability to be held until their maturity are stated at cost and adjusted for amortization of premiums and accretion of discounts. Transfers of debt securities into the held-to-maturity category from the available-for-sale category are made at fair value at the date of transfer. The unrealized gain or loss at the date of transfer is retained in other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts are amortized over the remaining life of the security. Certain securities with less than 15 % of their original purchase price remaining or that have experienced measurable credit deterioration may be sold. Cost method investments: Securities that do not have readily determinable fair values and for which Wesbanco does not exercise significant influence are carried at cost. Cost method investments consist primarily of Federal Home Loan Bank (“FHLB”) stock and are included in other assets in the Consolidated Balance Sheets. Cost method investments are evaluated for impairment whenever events or circumstances suggest that their carrying value may not be recoverable. Securities acquired in acquisitions are recorded at fair value with the premium or discount derived from the fair market value adjustment recognized into interest income on a level yield basis over the remaining life of the security. Gains and losses: Net realized gains and losses on sales of securities are included in non-interest income. The cost of securities sold is based on the specific identification method. The gain or loss is determined as of the trade date. Unrealized gains and losses on available-for-sale securities are recorded through other comprehensive income. Amortization and accretion: Generally, premiums are amortized to call date and discounts are accreted to maturity, on a level yield basis. Current expected credit losses (“CECL”): The corporate and municipal bonds in Wesbanco’s held-to-maturity debt portfolio are analyzed quarterly for CECL. Wesbanco uses a database of historical financials of all corporate and municipal issuers and actual historic default and recovery rates on rated and non-rated transactions to estimate CECL on an individual security basis. The CECL calculated amount is adjusted quarterly and is recorded in an allowance for expected credit losses on the balance sheet that is deducted from the amortized cost basis of the held-to-maturity portfolio as a contra asset, with the losses recorded on the income statement within the provision for credit losses. Because Wesbanco’s held-to-maturity investments in mortgage-backed securities and collateralized mortgage obligations are all either issued by a direct governmental entity or a government-sponsored entity, there is no historical evidence supporting the establishment of a CECL reserve; therefore, Wesbanco has estimated these losses at zero , and will monitor this assumption in the future for any economical or governmental policies that could affect this assumption. Available-for-sale debt security impairment: An available-for-sale debt security is considered impaired if its fair value is less than its amortized cost basis. If Wesbanco intends to sell or will be required to sell the investment prior to recovery of cost, the entire impairment will be recognized immediately in the Consolidated Statements of Income. If Wesbanco does not intend to sell, nor is it more likely than not that it will be required to sell, impaired securities prior to the recovery of their cost, a review is conducted each quarter to determine if any portion of the impairment is due to credit losses. In estimating credit losses, Wesbanco first considers the financial condition and near-term prospects of the issuer, evaluating any credit downgrades or other indicators of a potential credit problem, the type of security, either fixed or equity, and the receipt of principal and interest according to the contractual terms. If there are no indications that the impairment is credit-related, the impairment is recognized in other comprehensive income in the Consolidated Balance Sheet. If the impairment is considered to be credit-related based on management’s review of the various factors that indicate credit impairment, the amount of credit impairment is calculated using the present value of future expected cash flows. If the present value of future expected cash flows is less than the amortized cost basis of the security, a credit loss exists and an allowance for expected credit losses is recorded, limited by the total unrealized loss on the security, and is recognized in the Consolidated Statements of Income. The non-credit portion is calculated as the difference between the total unrealized loss and the credit portion of that loss and is recognized in other comprehensive income. Loans and Loans Held for Sale — Loans originated by Wesbanco are reported at the principal amount outstanding, net of unearned income including credit valuation adjustments, unamortized deferred loan fee income and loan origination costs. Interest is accrued as earned on loans except where doubt exists as to collectability, in which case accrual of income is discontinued. Loans originated and intended for sale are carried, in aggregate, at fair value. The use of a valuation model using quoted prices of similar instruments are significant observable inputs in arriving at the fair value of loans held for sale. Loan origination fees and direct costs are deferred and accreted or amortized into interest income, as an adjustment to the yield, over the life of the loan using the level yield method, or an approximation thereof. When a loan is paid off, the remaining unaccreted or unamortized net origination fees or costs are immediately recognized into income. Loans are generally placed on non-accrual when they are 90 days past due, unless the loan is well-secured and in the process of collection. Loans may be returned to accrual status when a borrower has resumed paying principal and interest for a sustained period of at least six months and Wesbanco is reasonably assured of collecting the remaining contractual principal and interest. Loans are returned to accrual status at an amount equal to the principal balance of the loan at the time of non-accrual status less any payments applied to principal during the non-accrual period. Loans are reported as a troubled debt restructuring when Wesbanco, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. Refer to the “Troubled Debt Restructurings” policy below for additional detail. A loan is considered non-performing, based on current information and events, if it is probable that Wesbanco will be unable to collect the payments of principal and interest when due according to the original contractual terms of the loan agreement. Non-performing loans include all non-accrual loans and troubled debt restructurings. Wesbanco recognizes interest income on non-accrual loans on the cash basis only if recovery of principal is reasonably assured. Consumer loans are charged down to the net realizable value at 120 days past due for closed-end loans and 180 days past due for open-end revolving lines of credit. Residential real estate loans are charged down to the net realizable value of the collateral at 180 days past due. Commercial loans are charged down to the net realizable value when it is determined that Wesbanco will be unable to collect the principal amount in full. Loans are reclassified to other assets at the net realizable value when foreclosure or repossession of the collateral occurs. Refer to the “Other Real Estate Owned and Repossessed Assets” policy below for additional detail. Troubled Debt Restructurings (“TDR”)— A restructuring of a loan constitutes a TDR if the creditor, for economic or legal reasons related to the debtor's financial difficulties, grants a concession to the debtor that it would not otherwise consider. The determination of whether a concession has been granted includes an evaluation of the debtor’s ability to access funds at a market rate for debt with similar risk characteristics and among other things, the significance of the modification relative to unpaid principal or collateral value of the debt, and/or the significance of a delay in the timing of payments relative to the frequency of payments, original maturity date, or the expected duration of the loan. The most common concessions granted generally include one or more modifications to the terms of the debt such as a reduction in the interest rate below the prevailing market rate for the remaining life of the debt, an extension of the maturity date at an interest rate lower than the prevailing market rate for new debt with similar risk, or reduction of the unpaid principal or interest. Additionally, all consumer bankruptcies are considered TDR; all TDRs are considered nonperforming loans. 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 restructuring 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 TDRs. 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. TDRs on accrual status generally remain on accrual as long as they continue to perform in accordance with their modified terms. TDRs may also be placed on non-accrual if they do not perform in accordance with the restructured terms. Loans may be removed from TDR status after they have performed according to the renegotiated terms for a period of time if the interest rate under the modified terms is at or above market, is restructured or refinanced at market or if the loan returns to its original terms. Acquired Loans— Loans acquired in connection with acquisitions are recorded at their acquisition-date fair value with no carryover of related allowance for credit losses. Acquired loans are classified into two categories; purchased financial instruments with more than insignificant credit deterioration (“PCD”) loans, and loans with insignificant credit deterioration (“non-PCD”). PCD loans are defined as a loan or group of loans that have experienced more than insignificant credit deterioration since origination. Non-PCD loans will have an allowance established on acquisition date, which is recognized in the current period provision for credit losses. For PCD loans, an allowance is recognized on day 1 by adding it to the fair value of the loan, which is the “Day 1 amortized cost”. There is no credit loss expense recognized on PCD loans because the initial allowance is established by grossing-up the amortized cost of the PCD loan. Determining the fair value of the acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Management considers a number of factors in evaluating the acquisition-date fair value including the remaining life of the acquired loans, delinquency status, estimated prepayments, payment options and other loan features, internal risk grade, estimated value of the underlying collateral and interest rate environment. PCD loans are accounted for in accordance with Accounting Standards Codification (“ASC”) 326-20, Financial Instruments – Credit Losses – Measure at Amortized Cost , if, at acquisition, the loan or pool of loans has experienced more-than-insignificant credit deterioration since origination. At acquisition, Wesbanco considers several factors as indicators that an acquired loan or pool of loans has experienced more-than-insignificant credit deterioration. These factors include, but are not limited to, loans 30 days or more past due, loans with an internal risk grade of below average or lower, loans classified as non-accrual by the acquired institution, the materiality of the credit and loans that have been previously modified in a troubled debt restructuring. Under ASC 326-20, a group of loans with similar risk characteristics can be assessed to determine if the pool of loans is PCD. However, if a loan does not have similar risk characteristics as any other acquired loan, the loan is individually assessed to determine if it is PCD. In addition, the initial allowance related to acquired loans can be estimated for a pool of loans if the loans have similar risk characteristics. Even if the loans were individually assessed to determine if they were PCD, they can be grouped together in the initial allowance calculation if they share similar risk characteristics. Since Wesbanco uses the discounted cash flow (DCF) approach, the initial allowance calculation for PCD loans is calculated as the expected contractual cash shortfalls, discounted at the rate that equals the net present value of estimated future cash flows expected to be collected with the purchase price of the loan(s). If a PCD loan has an unfunded commitment at acquisition, the initial allowance for credit losses calculation reflects only the expected credit losses associated with the funded portion of the PCD loan. Expected credit losses associated with the unfunded commitment are included in the initial measurement of the commitment. For PCD loans, the non-credit discount or premium is allocated to individual loans as determined by the difference between the loan’s amortized cost basis and the unpaid principal balance. The non-credit premium or discount is recognized into interest income on a level yield basis over the remaining expected life of the loan. For non-PCD loans, the interest and credit discount or premium is allocated to individual loans as determined by the difference between the loan’s amortized cost basis and the unpaid principal balance. The premium or discount is recognized into interest income on a level yield basis over the remaining expected life of the loan. Allowance for Credit Losses— The allowance for credit losses specific to loans reduces the loan portfolio to the net amount expected to be collected, representing the lifetime expected losses at the initial origination date. Similarly, an allowance for unfunded loan commitments, which is recorded in other liabilities, represents expected losses on unfunded commitments. Fluctuations in the allowance for credit losses specific to loans, the allowance for unfunded loan commitments, and the allowance for held-to-maturity debt securities are recognized in the provision for credit losses on the consolidated statement of operations. The allowance incorporates forward-looking information and applies a reversion methodology beyond the reasonable and supportable forecast. The allowance is increased by a provision charged to operating expense and reduced by charge-offs, net of recoveries. Management evaluates the appropriateness of the allowance at least quarterly. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change from period to period. The allowance for credit loss calculation specific to loans is based on the loan’s amortized cost basis, which is comprised of the unpaid principal balance of the loan, deferred loan fees (costs) and acquired premium (discount) minus any write-downs. Wesbanco made an accounting policy election to exclude accrued interest from the measurement of the allowance for credit losses because the Company has a policy in place to reverse or write-off accrued interest when a loan is placed on non-accrual, and also Wesbanco made an accounting policy election to reverse accrued interest deemed uncollectible as a reversal of interest income. However, Wesbanco is reserving, as part of the allowance for credit losses, for accrued interest on loan modifications under the CARES Act due to the nature and timing of these deferrals. The allowance for credit losses reflects the risk of loss on the loan portfolio. To appropriately measure expected credit losses, management disaggregates the loan portfolio into pools of similar risk characteristics. The Company utilizes the probability of default (“PD”) / loss given default (“LGD”) approach to calculate the expected loss for each segment, which is then discounted to net present value. PD is the probability the asset will default within a given timeframe and LGD is the percentage of the assets not expected to be collected due to default. The primary macroeconomic drivers of the quantitative model include forecasts of national unemployment and interest rate spreads. Management relies on macroeconomic forecasts obtained from various reputable sources, which may include the Federal Open Market Committee (FOMC) forecast and other publicly available forecasts from well recognized, leading economists. These forecasts can range from one to two years , depending upon the facts and circumstances of the current state of the economy, portfolio segment and management’s judgement of what can be reasonably supported. The model reversion period ranges from one to three years . The allowance for credit losses is calculated over the loan’s contractual life. For term loans, the contractual life is calculated based on the maturity date. For commercial and industrial (“C&I”) revolving loans with no stated maturity date, the contractual life is calculated based on the internal review date. For all other revolving loans, the contractual life is based on either the estimated maturity date or a default date. The contractual term does not include expected extensions, renewals or modifications unless management has a reasonable expectation as of the reporting period that Wesbanco will execute a TDR with the borrower. Management assumes a loan will become a TDR if a consumer loan has matured, has a principal balance, and has previously been partially charged-off. This assumption extends the maturity of these loans to six months beyond maturity date. The loan portfolio is segmented based on the risk profiles of the loans. Commercial loans are segmented between commercial real estate (“CRE”), which are collateralized by real estate, and C&I, which are typically utilized for general business purposes. CRE is further segmented between land and construction (“LCD”) and improved property, which are generally loans to purchase or refinance owner occupied or non-owner occupied investment properties. LCD loans have a unique risk that the developer or builder may not complete the project or not complete it on time or within budget. Improved property loans are reviewed for risk based on the underlying real estate property such as rental or owner income, appraisal value and other current lease terms, which affect debt service coverage and loan to value. Retail loans are a homogenous group, generally consisting of standardized products that are smaller in amount and distributed over a large number of individual borrowers. The group is segmented into three categories – residential real estate, HELOC and consumer. Contractual terms are adjusted for estimated prepayments to arrive at expected cash flows. Wesbanco models term loans with an annualized “prepayment” rate. When Wesbanco has a specific expectation of differing payment behavior for a given loan, the loan may be evaluated individually. For revolving loans that do not have a principal payment schedule, a curtailment rate is factored into the cash flow. The evaluation also considers qualitative factors such as economic trends and conditions, which includes levels of regional unemployment, real estate values and the impact on specific industries and geographical markets, changes in lending policies and underwriting standards, delinquency and other credit quality trends, concentrations of credit risk, if any, the results of internal loan reviews and examinations by bank regulatory agencies pertaining to the allowance for credit losses. Management relies on observable data from internal and external sources to the extent it is available to evaluate each of these factors and adjusts the model’s quantitative results to reflect the impact these factors may have on probable losses in the portfolio. Commercial loans, including CRE and C&I that have

At December 31, 2022 and 2021 there were no holdings of any one issuer, other than U.S. government sponsored entities and its agencies, in an amount greater than 10 % of Wesbanco’s shareholders’ equity. Equity securities, of which $ 9.0 million consist of investments in various mutual funds held in grantor trusts formed in connection with the Company’s deferred compensation plan, are recorded at fair value and totaled $ 11.5 million and $ 13.5 million at December 31, 2022 and 2021, respectively. The following table presents the amortized cost and fair value of available-for-sale and held-to-maturity debt securities by contractual maturity at December 31, 2022. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay debt obligations with or without prepayment penalties. Mortgage-backed securities and collateralized mortgage obligations are classified in the table below based on their contractual maturity date; however, regular principal payments and prepayments of principal are received on a monthly basis.

Proceeds from the sale of available-for-sale securities were $ 226.1 million for the year ended December 31, 2020. Net unrealized (losses) gains on available-for-sale securities included in accumulated other comprehensive income, net of tax, as December 31, 2022, 2021, and 2020 were ($ 261.8 ) million, ($ 4.7 ) million and $ 46.9 million, respectively. The following table presents the gross realized gains and losses on sales and calls of available-for-sale and held-to-maturity debt securities, as well as gains and losses on equity securities from both sales and market adjustments for the years ended December 31, 2022, 2021 and 2020, respectively. All gains and losses presented in the table below are included in the net securities gains (losses) line item of the income statement. For those equity securities relating to the key officer and director deferred compensation plan, the corresponding change in the obligation to the participant is recognized in employee benefits expense. For the Years Ended December 31, (in thousands) 2022 2021 2020 Debt securities: Gross realized gains $ 168 $ 252 $ 3,816 Gross realized losses ( 21 ) ( 57 ) ( 1,083 ) Net gains on debt securities $ 147 $ 195 $ 2,733 Equity securities: Unrealized (losses) gains recognized on securities still held $ ( 1,924 ) $ 918 $ 1,541 Net realized losses recognized on securities sold — — ( 6 ) Net (losses) gains on equity securities $ ( 1,924 ) $ 918 $ 1,535 Net securities (losses) gains $ ( 1,777 ) $ 1,113 $ 4,268 The corporate and municipal bonds in Wesbanco’s held-to-maturity debt portfolio are analyzed quarterly to determine if an allowance for current expected credit losses is warranted. Wesbanco uses a database of historical financials of all corporate and municipal issuers and actual historic default and recovery rates on rated and non-rated transactions to estimate expected credit losses on an individual security basis. The expected credit losses are adjusted quarterly and are recorded in an allowance for expected credit losses on the balance sheet, which is deducted from the amortized cost basis of the held-to-maturity portfolio as a contra asset. The losses are recorded on the income statement in the provision for credit losses. Accrued interest receivable on held-to-maturity securities, which was $ 9.5 million and $ 7.0 million as of December 31, 2022 and 2021 , respectively, is excluded from the estimate of credit losses. Held-to-maturity investments in U.S. Government sponsored entities and agencies as well as mortgage-backed securities and collateralized mortgage obligations, which are all either issued by a direct governmental entity or a government-sponsored entity, have no historical evidence supporting expected credit losses; therefore, Wesbanco has estimated these losses at zero , and will monitor this assumption in the future for any economical or governmental policies that could affect this assumption. The following table provides a roll-forward of the allowance for credit losses on held-to-maturity securities for the years ended December 31, 2022, 2021 and 2020, respectively: Allowance for Credit Losses By Category For the Years Ended December 31, 2022, 2021 and 2020 Residential mortgage -backed securities and collateralized mortgage obligations Obligations of U.S. Government of government state and Corporate sponsored sponsored entities political debt (in thousands) entities and agencies and agencies subdivisions Securities Total Beginning balance at January 1, 2022 $ — $ — $ 174 $ 94 $ 268 Current period provision — — ( 7 ) ( 41 ) ( 48 ) Write-offs — — — — — Recoveries — — — — — Ending balance at December 31, 2022 $ — $ — $ 167 $ 53 $ 220 Beginning balance at January 1, 2021 $ — $ — $ 130 $ 196 $ 326 Current period provision — — 44 ( 102 ) ( 58 ) Write-offs — — — — — Recoveries — — — — — Ending balance at December 31, 2021 $ — $ — $ 174 $ 94 $ 268 Beginning balance at January 1, 2020 $ — $ — $ 96 $ 133 $ 229 Current period provision — — 34 63 97 Write-offs — — — — — Recoveries — — — — — Ending balance at December 31, 2020 $ — $ — $ 130 $ 196 $ 326 The following tables provide information on unrealized losses on available-for-sale debt securities that have been in an unrealized loss position for less than twelve months and twelve months or more, for which an allowance for credit losses has not been recorded as of December 31, 2022 and 2021, respectively: December 31, 2022 Less than 12 months 12 months or more Total (dollars in thousands) Fair Unrealized # of Fair Unrealized # of Fair Unrealized # of U.S. Government sponsored $ 107,011 $ ( 8,435 ) 35 $ 118,779 $ ( 25,015 ) 13 $ 225,790 $ ( 33,450 ) 48 Residential mortgage-backed 514,789 ( 39,246 ) 294 1,328,906 ( 258,741 ) 202 1,843,695 ( 297,987 ) 496 Commercial mortgage-backed 190,189 ( 5,106 ) 38 159,543 ( 4,974 ) 36 349,732 ( 10,080 ) 74 Obligations of states and political 67,822 ( 1,815 ) 128 7,812 ( 2,282 ) 10 75,634 ( 4,097 ) 138 Corporate debt securities 7,225 ( 226 ) 3 4,433 ( 67 ) 3 11,658 ( 293 ) 6 Total temporarily impaired $ 887,036 $ ( 54,828 ) 498 $ 1,619,473 $ ( 291,079 ) 264 $ 2,506,509 $ ( 345,907 ) 762 December 31, 2021 Less than 12 months 12 months or more Total (dollars in thousands) Fair Unrealized # of Fair Unrealized # of Fair Unrealized # of U.S. Government sponsored $ 114,486 $ ( 1,865 ) 12 $ 32,688 $ ( 1,175 ) 4 $ 147,174 $ ( 3,040 ) 16 Residential mortgage-backed 1,568,138 ( 29,060 ) 143 141,681 ( 3,386 ) 23 1,709,819 ( 32,446 ) 166 Commercial mortgage-backed 131,970 ( 579 ) 25 78,356 ( 666 ) 8 210,326 ( 1,245 ) 33 Obligations of states and political 4,307 ( 35 ) 2 — — — 4,307 ( 35 ) 2 Corporate debt securities 6,990 ( 9 ) 5 — — — 6,990 ( 9 ) 5 Total temporarily impaired $ 1,825,891 $ ( 31,548 ) 187 $ 252,725 $ ( 5,227 ) 35 $ 2,078,616 $ ( 36,775 ) 222 Unrealized losses on debt securities in the tables above represent temporary fluctuations resulting from changes in market rates in relation to fixed yields. Unrealized losses in the available-for-sale portfolio are accounted for as an adjustment, net of taxes, to other comprehensive income in shareholders’ equity. Wesbanco does not believe the securities presented above are impaired due to reasons of credit quality, as substantially all debt securities are rated above investment grade and all are paying principal and interest according to their contractual terms. Wesbanco does not intend to sell, nor is it more likely than not that it will be required to sell, loss position securities prior to recovery of their cost, and therefore, management believes the unrealized losses detailed above do not require an allowance for credit losses relating to these securities to be recognized. Securities that do not have readily determinable fair values and for which Wesbanco does not exercise significant influence are carried at cost. Cost method investments consist primarily of FHLB stock totaling $ 36.2 million and $ 15.9 million at December 31, 2022 and 2021 , respectively, and are included in other assets in the Consolidated Balance Sheets. Cost method investments are evaluated for impairment whenever events or circumstances suggest that their carrying value may not be recoverable.

Loans and the Allowance for Credit Losses	NO TE 4. LOANS AND THE ALLOWANCE FOR CREDIT LOSSES The recorded investment in loans is presented in the Consolidated Balance Sheets net of deferred loan fees and costs, and discounts on purchased loans. Net deferred loan costs were $ 9.6 million and $ 3.3 million at December 31, 2022 and 2021 , respectively, including $ 0.2 million and $ 6.1 million, respectively, of net deferred income from SBA Payroll Protection Program ("PPP") loans. The un-accreted discount on purchased loans from acquisitions was $ 18.0 million at December 31, 2022 and $ 25.9 million at December 31, 2021.

Wesbanco made an accounting policy election to exclude accrued interest from the measurement of the allowance for credit losses because the Company has a robust policy in place to reverse or write-off accrued interest when loans are placed on non-accrual. However, Wesbanco does have a $ 0.2 million reserve on the accrued interest related to loan modifications allowed under the CARES Act due to the timing and nature of these modifications. As of December 31, 2022 , accrued interest related to COVID-19 loan modifications as permitted under the CARES Act was $ 17.0 million.

Commercial loan risk grades are determined based on an evaluation of the relevant characteristics of each loan, assigned at inception and adjusted thereafter at any time to reflect changes in the risk profile throughout the life of each loan. The primary factors used to determine the risk grade are the sufficiency, reliability and sustainability of the primary source of repayment and overall financial strength of the borrower. The rating system more heavily weights the debt service coverage, leverage and loan to value factors to derive the risk grade. Other factors that are considered at a lesser weighting include management, industry or property type risks, payment history, collateral or guarantees. Commercial real estate – land and construction consists of loans to finance investments in vacant land, land development, construction of residential housing, and construction of commercial buildings. Commercial real estate – improved property consists of loans for the purchase or refinance of all types of improved owner-occupied and investment properties. Factors that are considered in assigning the risk grade vary depending on the type of property financed. The risk grade assigned to construction and development loans is based on the overall viability of the project, the experience and financial capacity of the developer or builder to successfully complete the project, project specific and market absorption rates and comparable property values, and the amount of pre-sales for residential housing construction or pre-leases for commercial investment property. The risk grade assigned to commercial investment property loans is based primarily on the adequacy of the net operating income generated by the property to service the debt (“debt service coverage”), the loan to appraised value, the type, quality, industry and mix of tenants, and the terms of leases. The risk grade assigned to owner-occupied commercial real estate is based primarily on global debt service coverage and the leverage of the business, but may also consider the industry in which the business operates, the business’ specific competitive advantages or disadvantages, collateral margins and the quality and experience of management. C&I loans consist of revolving lines of credit to finance accounts receivable, inventory and other general business purposes; term loans to finance fixed assets other than real estate, and letters of credit to support trade, insurance or governmental requirements for a variety of businesses. Most C&I borrowers are privately-held companies with annual sales up to $ 100 million. Primary factors that are considered in risk rating C&I loans include debt service coverage and leverage. Other factors including operating trends, collateral coverage along with management experience are also considered. Pass loans are those that exhibit a history of positive financial results that are at least comparable to the average for their industry or type of real estate. The primary source of repayment is acceptable and these loans are expected to perform satisfactorily during most economic cycles. Pass loans typically have no significant external factors that are expected to adversely affect these borrowers more than others in the same industry or property type. Any minor unfavorable characteristics of these loans are outweighed or mitigated by other positive factors including but not limited to adequate secondary or tertiary sources of repayment. Criticized loans, considered as compromised, have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the bank's credit position at some future date. Criticized loans are not adversely classified by the banking regulators and do not expose the bank to sufficient risk to warrant adverse classification. Classified loans, considered as substandard and doubtful, are equivalent to the classifications used by banking regulators. Substandard loans are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the bank will sustain some loss if the deficiencies are not corrected. These loans may or may not be reported as non-accrual. Doubtful loans have all the weaknesses inherent in those classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions, and values, highly questionable and improbable. These loans are reported as non-accrual.

Wesbanco primarily evaluates the credit quality of residential real estate, home equity and consumer loans based on repayment performance and historical loss rates. The aggregate amount of residential real estate, home equity and consumer loans classified as substandard in accordance with regulatory guidelines were $ 24.8 million at December 31, 2022 and $ 30.2 million at December 31, 2021 , of which $ 5.9 million and $ 7.4 million were accruing, for each period, respectively. These loans are not included in the tables above.

The concessions granted in the majority of loans reported as accruing and non-accrual TDRs are extensions of the maturity date or the amortization period, reductions in the interest rate below the prevailing market rate for loans with comparable characteristics, and/or permitting interest-only payments for longer than six months . Wesbanco had unfunded commitments to debtors whose loans were classified as nonperforming of $ 0.1 million as of both December 31, 2022 and 2021.

The following table summarizes TDRs which defaulted (defined as past due 90 days) during the years ended December 31, 2022 and 2021 that were restructured within the last twelve months prior to December 31, 2022 and 2021: Defaulted TDRs (1) Defaulted TDRs (1) (dollars in thousands) Number of Recorded Number of Recorded Commercial real estate: Land and construction — $ — — $ — Improved property — — — — Total commercial real estate — — — — Commercial and industrial — — — — Residential real estate — — 1 234 Home equity — — — — Consumer — — — — Total — $ — 1 $ 234 (1) Excludes loans that were either charged-off or cured by period end. The recorded investment is as of December 31, 2022 and 2021 . TDRs that default are placed on non-accrual status unless they are both well-secured and in the process of collection. The loans in the table above were not accruing interest. Section 4013 of the CARES Act allows financial institutions the option to temporarily suspend certain requirements under GAAP related to TDRs for a limited period of time during the COVID-19 pandemic. These customers must meet certain criteria, such as they were in good standing and not more than 30 days past due either as of December 31, 2019, or as of the implementation of the modification program under the Interagency Statement, as well as other requirements noted in the regulatory agencies’ revised statement. Based on this guidance, Wesbanco does not classify the COVID-19 loan modifications as TDRs, nor are the customers considered past due with regard to their delayed payments. Upon exiting the loan modification deferral program, the measurement of loan delinquency will resume where it left off upon entry into the program. Under the CARES Act, Wesbanco has modified approximately 3,600 loans totaling $ 2.2 billion, of which $ 0.8 million remain in their deferral period as of December 31, 2022 . Wesbanco originally offered three to six months of deferred payments to commercial and retail customers impacted by the COVID-19 pandemic depending on the type of loan and the industry for commercial loans. In the fourth quarter of 2020, Wesbanco offered up to an additional twelve months of deferred payments to certain commercial loan customers, predominantly in the hospitality industry, based on specific criteria related to the borrower, the underlying property and the potential for guarantors / co-borrowers.

Operating leases are recorded as a right of use (“ROU”) asset and operating lease liability, included in premises and equipment, net and other liabilities, respectively, on the consolidated balance sheet. Operating lease ROU assets represent the right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate at the lease commencement date. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded primarily in net occupancy expense in the consolidated statements of comprehensive income. Operating leases relate primarily to bank branches, office space and license agreements with remaining lease terms of generally 1 to 30 years , which include options for multiple five and ten year extensions, with a weighted average lease term of 16.0 years. As of December 31, 2022 , operating lease ROU assets and liabilities were $ 38.8 million and $ 43.0 million, respectively, and as of December 31, 2021 , operating lease ROU assets and liabilities were $ 43.1 million and $ 47.5 million, respectively. The lease expense for operating leases was $ 4.6 million, $ 5.2 million and $ 5.8 million for the years ended December 31, 2022, 2021 and 2020 , respectively.

Investments in Limited Partnerships	N OTE 7. INVESTMENTS IN LIMITED PARTNERSHIPS Wesbanco is a limited partner in several tax-advantaged limited partnerships whose purpose is to invest in approved low-income housing investment tax credit projects. These investments are accounted for using the equity method of accounting and are included in other assets in the Consolidated Balance Sheets. The limited partnerships are considered to be VIEs as they generally do not have equity investors with voting rights or have equity investors that do not provide sufficient financial resources to support their activities. The VIEs have not been consolidated because Wesbanco is not considered the primary beneficiary. All of Wesbanco’s investments in limited partnerships are privately held, and their market values are not readily available. As of December 31, 2022 and 2021 , Wesbanco had $ 34.2 million and $ 27.9 million, respectively, invested in these partnerships. Wesbanco also recognizes the unconditional unfunded equity commitments of $ 15.1 million and $ 12.5 million at December 31, 2022 and 2021, respectively, in other liabilities. Wesbanco classifies the amortization of the investment as a component of income tax expense (benefit) and proportionally amortizes the investment over the tax credit period. The amount for the years ended December 31, 2022, 2021 and 2020 was $ 3.6 million, $ 3.4 million and $ 3.3 million, respectively. Tax benefits attributed to these partnerships include low-income housing and historic tax credits which totaled $ 3.5 million, $ 3.1 million and $ 3.2 million for the years ended December 31, 2022, 2021 and 2020, respectively, which are also included in income tax expense. Wesbanco is also a limited partner in five other limited partnerships as of December 31, 2022. These provide seed money and capital to startup companies, and financing to low-income housing projects. As of December 31, 2022 and 2021 , Wesbanco had $ 3.3 million and $ 9.9 million, respectively, invested in these partnerships, which are recorded in other assets using the equity method. Wesbanco included in operations under the equity method of accounting its share of the partnerships’ net (loss) income of ($ 0.9 ) million, $ 3.6 million and ($ 0.6 ) million for the years ended December 31, 2022, 2021 and 2020 , respectively. (Losses) gains totaling ($ 1.0 ) million and $ 3.8 million related to the sale and the change in the fair value of the underlying investments funded by Wesbanco's Community Development Corporation, which is included within the partnerships' net income for the years ended December 31, 2022 and December 31, 2021, respectively. This income is located within net gain (loss) on other real estate owned and other assets on the consolidated statements of income and predominantly relates to the sale and fair value changes in the underlying Tech Growth investment, which was sold in 2022.

SUBORDINATED DEBT AND JUNIOR SUBORDINATED DEBT Wesbanco completed the issuance of $ 150.0 million in aggregate principal amount of subordinated debentures on March 23, 2022. The subordinated debentures have a fixed rate of 3.75 % for the first five years and a floating rate for the next five years at Three Month Term Secured Overnight Financing Rate ("SOFR") plus a spread of 1.787 %. The subordinated debentures are callable after five years, mature on April 1, 2032 and count towards Tier 2 Capital. Certain trusts, consisting of Wesbanco Capital Trust II, Wesbanco Capital Statutory Trust III, Wesbanco Capital Trusts IV, V and VI, Oak Hill Capital Trusts 2, 3 and 4, Community Bank Shares Statutory Trusts I and II and First Federal Statutory Trust II are all wholly-owned trust subsidiaries of Wesbanco formed for the purpose of issuing Trust Preferred Securities (“Trust Preferred Securities”) into a pool of other financial services entity trust preferred securities, and lending the proceeds to Wesbanco. The Trust Preferred Securities were issued and sold in private placement offerings. The proceeds from the sale of the securities and the issuance of common stock by the Trusts were invested in Junior Subordinated Deferrable Interest Debentures (“Junior Subordinated Debt”) issued by Wesbanco and former acquired banks, which are the sole assets of the Trusts. The Trusts pay dividends on the Trust Preferred Securities at the same rate as the distributions paid by Wesbanco on the Junior Subordinated Debt held by the Trusts. The Trusts provide Wesbanco with the option to defer payment of interest on the Junior Subordinated Debt for an aggregate of 20 consecutive quarterly periods . Should any of these options be utilized, Wesbanco may not declare or pay dividends on its common stock during any such period. Undertakings made by Wesbanco with respect to the Trust Preferred Securities for the Trusts constitute a full and unconditional guarantee by Wesbanco of the obligations of these Trust Preferred Securities. The Junior Subordinated Debt is presented as a separate category of long-term debt on the Consolidated Balance Sheets. For regulatory purposes, at December 31, 2022, all such securities are counted as Tier 2 capital subject to limits. The Trust Preferred Securities provide the issuer with a unique capital instrument that has a tax-deductible interest feature not normally associated with the equity of a corporation.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	NO TE 11. DERIVATIVES AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives Wesbanco is exposed to certain risks arising from both its business operations and economic conditions. Wesbanco principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. Wesbanco manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its assets and liabilities. Wesbanco’s existing interest rate derivatives result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in Wesbanco’s assets or liabilities. Wesbanco manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. A matched book is when the Bank’s assets and liabilities are equally distributed but also have similar maturities. Loan Swaps Wesbanco executes interest rate swaps and interest rate caps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps and caps are simultaneously economically hedged by offsetting interest rate swaps and caps that Wesbanco executes with a third party, such that Wesbanco minimizes its net risk exposure resulting from such transactions. As the interest rate swaps and caps associated with this program do not meet the hedge accounting requirements of ASC 815, changes in the fair value of both the customer swaps and caps and the offsetting third-party swaps and caps are recognized directly in earnings. As of December 31, 2022 and 2021 , Wesbanco had 159 and 135 , respectively, interest rate swaps and caps with an aggregate notional amount of $ 936.8 million and $ 730.6 million, respectively, related to this program. Wesbanco recognized $ 4.4 million, $ 4.5 million and $ 8.1 million of income for the related swap and cap fees for the years ended December 31, 2022, 2021 and 2020, respectively. Risk participation agreements are entered into as financial guarantees of performance on interest rate swap derivatives. The purchased asset or sold liability allows Wesbanco to participate-in (fee received) or participate-out (fee paid) the risk associated with certain derivative positions executed by the borrower of the lead bank in a loan syndication. As of December 31, 2022 and 2021 , Wesbanco had 16 and 13 , respectively, risk participation-in agreements with an aggregate notional amount of $ 187.8 million and $ 128.2 million, respectively. As of December 31, 2022 and 2021 , Wesbanco had one risk participation-out agreement with an aggregate notional amount of $ 9.6 million and $ 9.8 million, respectively. Mortgage Loans Held for Sale and Interest Rate Lock Commitments Certain residential mortgage loans are originated for sale in the secondary mortgage loan market. These loans are classified as held for sale and carried at fair value as Wesbanco has elected the fair value option. Fair value is determined based on rates obtained from the secondary market for loans with similar characteristics. Wesbanco sells loans to the secondary market on either a mandatory or best efforts basis. The loans sold on a mandatory basis are not committed to an investor until the loan is closed with the borrower. Wesbanco enters into forward to be announced (“TBA”) contracts to manage the interest rate risk between the lock commitment and the closing of the loan. The total balance of forward TBA contracts entered into was $ 14.5 million and $ 48.5 million at December 31, 2022 and December 31, 2021, respectively. The loans sold on a best efforts basis are committed to an investor simultaneous to the interest rate commitment with the borrower, and as a result, the Company does not enter into a separate forward TBA contract to offset the fair value risk, as the investor accepts such risk in exchange for a lower premium on sale. Fair Values of Derivative Instruments on the Balance Sheet All derivatives are carried on the consolidated balance sheet at fair value. Derivative assets are classified in the consolidated balance sheet under other assets, and derivative liabilities are classified in the consolidated balance sheet under other liabilities. Changes in fair value are recognized in earnings. None of Wesbanco’s derivatives are designated in qualifying hedging relationships under ASC 815. The table below presents the fair value of Wesbanco’s derivative financial instruments as well as their classification on the Balance Sheet as of December 31, 2022 and 2021: December 31, 2022 December 31, 2021 (in thousands) Notional or Asset Derivatives Liability Derivatives Notional or Asset Derivatives Liability Derivatives Derivatives Loan Swaps: Interest rate swaps and caps $ 936,834 $ 75,840 $ 74,683 $ 730,552 $ 24,867 $ 26,388 Other contracts: Interest rate lock commitments 10,071 — 43 28,994 9 — Forward TBA contracts 14,500 53 — 48,500 — 21 Total derivatives $ 75,893 $ 74,726 $ 24,876 $ 26,409 Effect of Derivative Instruments on the Income Statement The table below presents the change in the fair value of the Company’s derivative financial instruments reflected within the other non-interest income line item of the consolidated income statement for the years ended December 31, 2022, 2021 and 2020, respectively.

Wesbanco also has agreements with certain of its derivative counterparties that contain a provision where if Wesbanco fails to maintain its status as either a “well-" or “adequately-capitalized” institution, then the counterparty could terminate the derivative positions and Wesbanco would be required to settle its obligations under the agreements. Dependent upon the net present value of the underlying swaps, Wesbanco has minimum collateral posting thresholds with certain of its derivative counterparties. If Wesbanco had breached any of these provisions at December 31, 2022 , it could have been required to settle its obligations under the agreements at the termination value and would have been required to pay any additional amounts due in excess of amounts previously posted as collateral with the respective counterparty. In certain market situations, Wesbanco can also request collateral from the derivative counterparties. Due to the current rise in interest rates, as of December 31, 2022, Wesbanco is holding collateral from various derivative counterparties with a market value of $ 42.7 million.

Employee Benefit Plans	NOT E 12. EMPLOYEE BENEFIT PLANS Defined Benefit Pension Plan— The Wesbanco, Inc. Defined Benefit Pension Plan (“the Plan”) established on January 1, 1985, is a non-contributory, defined benefit pension plan. The Plan covers all employees of Wesbanco and its subsidiaries who were hired on or before August 1, 2007 who satisfy minimum age and length of service requirements. Benefits of the Plan are generally based on years of service and the employee’s compensation during the last five years of employment. Contributions are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future. Wesbanco uses a December 31 measurement date for the Plan. The benefit obligations and funded status of the Plan are as follows: December 31, (dollars in thousands) 2022 2021 Accumulated benefit obligation at end of year $ 120,241 $ 152,232 Change in projected benefit obligation: Projected benefit obligation at beginning of year $ 163,919 $ 168,433 Service cost 2,190 2,500 Interest cost 4,114 3,416 Actuarial (gain) loss ( 36,981 ) ( 4,688 ) Benefits paid ( 6,115 ) ( 5,742 ) Projected benefit obligation at end of year $ 127,127 $ 163,919 Change in fair value of plan assets: Fair value of plan assets at beginning of year $ 202,783 $ 185,716 Actual return on plan assets ( 29,762 ) 22,809 Employer contribution — — Benefits paid ( 6,115 ) ( 5,742 ) Fair value of plan assets at end of year $ 166,906 $ 202,783 Amounts recognized in the statement of financial position: Funded status $ 39,779 $ 38,864 Net amounts recognized as receivable pension costs in the $ 39,779 $ 38,864 Amounts recognized in accumulated other comprehensive Unrecognized prior service credit $ ( 159 ) $ ( 193 ) Unrecognized net loss 6,548 2,700 Net amounts recognized in accumulated other comprehensive $ 6,389 $ 2,507 Weighted average assumptions used to determine benefit obligations: Discount rate 5.23 % 3.03 % Rate of compensation increase 3.84 % 3.62 % Expected long-term return on assets 6.82 % 5.74 % The components of and weighted-average assumptions used to determine net periodic benefit costs are as follows: For the Years Ended December 31, (dollars in thousands) 2022 2021 2020 Components of net periodic benefit cost: Service cost—benefits earned during year $ 2,190 $ 2,500 $ 2,283 Interest cost on projected benefit obligation 4,114 3,416 4,507 Expected return on plan assets ( 11,572 ) ( 11,207 ) ( 10,433 ) Amortization of prior service credit ( 34 ) ( 34 ) ( 34 ) Amortization of net loss 506 2,736 3,192 Net periodic pension income $ ( 4,796 ) $ ( 2,589 ) $ ( 485 ) Other changes in plan assets and benefit obligations recognized in other Net loss (gain) for period $ 4,353 $ ( 16,290 ) $ 432 Prior service credit — — ( 313 ) Amortization of prior service credit 34 34 34 Amortization of net loss ( 505 ) ( 2,736 ) ( 3,192 ) Total recognized in other comprehensive loss (income) $ 3,882 $ ( 18,992 ) $ ( 3,039 ) Total recognized in net periodic pension cost and other comprehensive $ ( 914 ) $ ( 21,581 ) $ ( 3,524 ) Weighted-average assumptions used to determine net periodic Discount rate 3.03 % 2.74 % 3.38 % Rate of compensation increase 3.62 % 3.30 % 3.53 % Expected long-term return on assets 5.74 % 6.11 % 6.30 % As permitted under ASC 715-30-35-13, the amortization of any prior service cost is determined using a straight-line amortization of the cost over the average remaining service period of employees expected to receive benefits under the Plan. The expected long-term rate of return for the Plan’s total assets is based on the expected return of each of the Plan asset categories, weighted based on the median of the target allocation for each class. Pension Plan Investment Policy and Strategy— The investment policy as established by the Pension and Post-Retirement Plan Committee, to be followed by the Trustee, which is Wesbanco’s Trust and Investment Services department, is to invest assets based on the target allocations shown in the table below. Assets are reallocated periodically by the Trustee based on the ranges set forth by the Committee to meet the target allocations. The investment policy is also subject to review periodically to determine if the policy should be changed. Plan assets are to be invested with the principal objective of maximizing long-term total return without exposing Plan assets to undue risk, taking into account the Plan’s funding needs and benefit obligations. Assets are to be invested in a balanced portfolio composed primarily of equities, fixed income, alternative asset funds and cash or cash equivalent money market investments. In 2021, the Committee adopted certain changes to the investment policy for the Defined Benefit Pension Plan that recognizes over time the return requirements and risk tolerance of the plan will change. Based on an assessment of the long-term goals and desired risk levels, the Committee approved the development of a glide path that adjusts the target allocations as the Plan’s funded status changes. Given the United States pension regulations and demographics of the Plan, a more risk averse investment approach is deemed appropriate to reduce the funded status volatility. Thus, modifications were made to the return seeking portfolio and the liability hedging portfolio as detailed in the plan. The revised Plan notes that return seeking assets generally consist of investments that focus on price appreciation with returns that, over the long term, are above the interest costs of the Plan. Thus, the policy set target allocations to return seeking assets and rebalanced the ranges for the same. Additionally, the investment policy statement was changed to note that liability hedging assets will be investment grade fixed income investments and are expected to generally behave like the Plan’s liabilities. Since these assets focus mainly on current income, their expected long-term returns will generally be lower than return seeking assets. The policy provides that based on the hedge path, the mix of short term, intermediate term, and long term fixed income holdings will vary. As a result, there will not be set target allocations and ranges for each maturity category, but rather to the hedge path target. Changes to the Plan’s holdings, as noted in the chart below, reflect the changes implemented pursuant to the change in the investment policy statement. At December 31, 2022 and 2021 , the Plan’s equity securities included 55,300 shares of Wesbanco common stock with a fair market value of $ 2.0 million and $ 1.9 million, respectively. The following table sets forth the Plan’s weighted-average asset allocations by asset category: Target Allocation December 31, for 2022 2022 2021 Asset Category: Equity securities 55 - 75 % 50 % 55 % Debt securities 25 - 55 % 48 % 43 % Cash and cash equivalents 0 - 5 % 2 % 2 % Total 100 % 100 % The fair values of Wesbanco’s pension plan assets at December 31, 2022 and 2021, by asset category are as follows: December 31, 2022 Fair Value Measurements Using: (in thousands) Assets at Fair Quoted Prices in Significant Significant Defined benefit pension plan assets: Registered investment companies $ 42,622 $ 42,622 $ — $ — Equity securities 52,914 52,914 — — Corporate debt securities 58,342 — 58,342 — Municipal obligations 1,764 — 1,764 — Residential mortgage-backed securities and collateralized 10,102 — 10,102 — Total defined benefit pension plan assets (1) $ 165,744 $ 95,536 $ 70,208 $ — (1) The defined benefit pension plan statement of net assets also includes cash, accrued interest and dividends, and due to/from brokers resulting in net assets available for benefits of $ 166.9 million.

Cash Flows— Wesbanco has no required minimum contribution to the Plan for 2023 and as of December 31, 2022 does no t expect to make a voluntary contribution in 2023. Wesbanco did no t make a contribution to the Plan in 2020, 2021 or 2022.

The plan covers FFKT employees who were hired before January 1, 2016 and meet certain age and length of full-time service requirements. The plan was modified in August 2018, which reduced the number of eligible employees. The modification resulted in a $ 5.5 million unrealized gain, which was recorded in accumulated other comprehensive income, net of tax, and will be recognized over the life of the plan participants estimated to be approximately 17 years. Benefits provided under this plan are unfunded, and payments to the plan participants are made by Wesbanco. The benefit obligation and funded status of the plan are as follows: December 31, (dollars in thousands) 2022 2021 Change in projected benefit obligation: Projected benefit obligation $ 11,245 $ 12,695 Interest cost 266 230 Actuarial gain ( 3,881 ) ( 1,096 ) Participant contributions 320 342 Benefits paid ( 831 ) ( 926 ) Projected benefit obligation at end of year $ 7,119 $ 11,245 Amounts recognized in the statement of financial position: Funded status $ 7,119 $ ( 11,245 ) Net amounts recognized as receivable pension costs in the consolidated balance sheets $ 7,119 $ ( 11,245 ) Amounts recognized in accumulated other comprehensive income consist of: Unrecognized net (gain) loss $ ( 3,676 ) $ 249 Prior service cost ( 2,343 ) ( 2,568 ) Net amounts recognized in accumulated other comprehensive income (before tax) $ ( 6,019 ) $ ( 2,319 ) Weighted average assumptions used to determine benefit obligations: Discount rate 5.20 % 2.96 % Rate of compensation increase NA NA Expected long-term return on assets NA NA The components of and weighted-average assumptions used to determine net periodic benefit costs are as follows: For the Years Ended December 31, (dollars in thousands) 2022 2021 Components of net periodic benefit cost: Interest cost on projected benefit obligation $ 266 $ 230 Amortization of prior service credit ( 224 ) ( 224 ) Amortization of net loss 43 43 Net periodic pension cost $ 85 $ 49 Other changes in plan benefit obligations recognized in other comprehensive income: Prior service cost for period $ — $ — Net gain for the period ( 3,881 ) ( 1,097 ) Amortization of prior service credit 224 224 Amortization of net loss ( 43 ) ( 43 ) Total recognized in other comprehensive income $ ( 3,700 ) $ ( 916 ) Total recognized in net periodic pension cost and other comprehensive income $ ( 3,615 ) $ ( 867 ) Weighted-average assumptions used to determine net periodic pension cost: Discount rate 5.10 % 2.40 % Rate of compensation increase NA NA Expected long-term return on assets NA NA The following table presents estimated benefits to be paid in each of the next five years and in aggregate for all years thereafter (in thousands) : Year Amount 2023 $ 684 2024 668 2025 603 2026 588 2027 536 2028 and thereafter 10,138 Total $ 13,217 Employee Stock Ownership and 401(k) Plan (“KSOP”) — Wesbanco sponsors a KSOP plan consisting of a non-contributory leveraged ESOP and a contributory 401(k) profit sharing plan covering substantially all of its employees. Under the provisions of the 401(k) plan, Wesbanco matches a portion of eligible employee contributions based on rates established and approved by the Board of Directors. For each of the past three years, Wesbanco matched 100 % of the first 3 % and 50 % of the next 2 % of eligible employee contributions. No ESOP contribution has been made for any of the past three years. Total expense for the KSOP was $ 5.5 million, $ 5.3 million and $ 5.3 million in 2022, 2021 and 2020, respectively. As of December 31, 2022 , the KSOP held 443,848 shares of Wesbanco common stock of which all shares were allocated to specific employee accounts. Dividends on shares are either distributed to employee accounts or paid in cash to the participant. Wesbanco had 165,438 and 207,199 shares registered on Form S-8 remaining for future issuance under the KSOP plan at December 31, 2022 and 2021, respectively. Incentive Bonus, Option and Restricted Stock Plan— The Incentive Bonus, Option and Restricted Stock Plan (the “Incentive Plan”), is a non-qualified plan that includes the following components: an Annual Bonus and a Long-Term Incentive, which included a Total Shareholder Return Plan, a Stock Option component, and a Restricted Stock component for certain key officers of the Company. The components allow for payments of cash, a mixture of cash and stock, granting of stock options, or granting of restricted stock, depending upon the component of the Incentive Plan in which the award is earned, through the attainment of certain performance goals or time-based vesting requirements. Performance goals or service vesting requirements are established by Wesbanco’s Compensation Committee. On April 22, 2021, Wesbanco registered an additional 2,000,000 shares of Wesbanco common stock for issuance under the Incentive Plan. Wesbanco had 1,468,140 and 1,788,174 shares registered on Form S-8 remaining for future issuance under equity compensation plans at December 31, 2022 and 2021, respectively. Annual Bonus Compensation expense for key officers for the Annual Bonus w as $ 4.4 million, $ 3.5 million and $ 1.7 million for 2022, 2021 and 2020, respectively. Stock Options On May 18, 2022, Wesbanco granted 146,900 stock options to selected participants, including certain named executive officers at an exercise price of $ 32.30 per share. The options granted in 2022 are service-based and vest in two equal installments on May 18, 2023 and December 31, 2023, and expire seven years from the date of grant. Compensation expense for the stock option component of the Incentive Plan was $ 1.1 m illion, $ 0.8 million and $ 0.6 million for 2022, 2021 and 2020, respectively. At December 31, 2022, the total unrecognized compensation expense related to non-vested stock option grants totaled $ 0.5 million, wi th an expense recognition period of one year remaining. The maximum term of options granted under Wesbanco’s stock option plan is ten years from the original grant date; however, options granted in 2022 had a term of seven years . The total intrinsic value of options exercised was $ 1.0 m illion for the years ended December 31, 2022 and 2021 , respectively. The cash received and related tax benefit realized from stock options exercised was $ 3.0 million an d $ 0.3 mi llion in 2022 and was $ 2.4 million and $ 0.2 million in 2021. Shares issued in connection with options exercised are issued from treasury shares acquired under Wesbanco’s share repurchase plans or from issuance of authorized but unissued shares, subject to prior SEC registration. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. Additionally, there may be other factors that might otherwise have a significant effect on the value of stock options granted that are not considered by the model. The following table sets forth the significant assumptions used in calculating the fair value of the grants: For the Years Ended December 31, 2022 2021 2020 Weighted-average life 5.1 years 5.2 years 5.7 years Risk-free interest rate 2.89 % 0.87 % 0.41 % Dividend yield 4.15 % 3.32 % 5.94 % Volatility factor 32.28 % 31.81 % 28.38 % Fair value of the grants $ 6.91 $ 7.75 $ 2.54 The weighted-average life assumption is an estimate of the length of time that an employee might hold an option before option exercise, option expiration or employment termination. The weighted-average life assumption was developed using historical experience. Wesbanco used a weighted historical volatility of its common stock price over the weighted average life prior to each issuance as the volatility factor assumption, adjusted for abnormal volatility during certain periods, and current and future dividend payment expectations for the dividend assumption. The following table shows the activity for the Stock Option component of the Incentive Plan: For the Year Number Weighted Outstanding at beginning of the year 772,651 $ 34.70 Granted during the year 146,900 32.30 Exercised during the year ( 111,050 ) 27.46 Forfeited or expired during the year ( 27,031 ) 32.37 Outstanding at end of the year 781,470 $ 36.12 Exercisable at year end 637,670 $ 36.98 The aggregate intrinsic value of the outstanding shares and the shares exercisable at year-end was $ 2.3 million and $ 1.6 million, respectively. The following table shows the average remaining life of the stock options at December 31, 2022: Year Issued Exercisable Exercise Options Weighted Weighted Avg. 2013 2,824 15.35 2,824 $ 15.35 0.16 2014 4,705 21.37 4,705 21.37 1.16 2015 9,725 18.33 to 20.18 9,725 19.82 2.62 2016 36,405 22.63 to 32.37 36,405 31.11 0.75 2017 96,325 38.88 96,325 38.88 1.35 2018 160,186 36.97 to 45.65 160,186 43.21 3.23 2019 114,000 38.93 114,000 38.93 3.37 2020 73,800 21.55 73,800 21.55 4.40 2021 139,700 38.78 139,700 38.78 5.39 2022 — — 143,800 32.30 6.38 Total 637,670 $ 15.35 to $ 45.65 781,470 $ 36.12 3.95 Restricted Stock During 2022 , Wesbanco granted 176,703 shares of service-based restricted stock to certain officers and directors, which cliff vest 36 months from the date of grant. The weighted average fair value of the restricted stock granted was $ 32.33 per share. The restricted stock grant provides the recipient with voting rights from the date of issuance. Dividends paid on these restricted shares during the restriction period are converted into additional shares of restricted stock on the date the cash dividend would have otherwise been paid, but do not vest until the related grant of the restricted shares complete their vesting. The Compensation Committee has discretion to elect to pay such dividends in cash to participants. Voting rights accrue from date of issuance of these shares. Wesbanco also granted 24,444 shares of performance-based restricted stock ("PBRS") to select officers. These shares have a three-year performance period, beginning January 1, 2023, based on Wesbanco’s return on average assets and return on average tangible common equity measured for each year, compared to a national peer group of financial institutions with total assets between approximately $ 11.6 billion and $ 29.0 billion. Earned performance-based restricted shares are subject to additional service-based vesting with 50 % vesting on May 18, 2026 after the completion of the three-year performance period and the final 50 % vesting on May 18, 2027. For the 2018, 2019 and 2020 PBRS, the third, second and first year reporting periods, respectively, achieved 100 % of the performance goal measured at December 31, 2021. The Compensation Committee approved these goal achievements in May of 2022, and Wesbanco issued 2,694 time-based restricted shares to the select officers of the 2018 grant, of which 1,347 shares vested on May 16, 2022 and the remaining 1,347 shares will vest on May 16, 2023. For the 2019 PBRS awards, Wesbanco issued 5,352 shares to the select officers of which 2,676 will vest on May 15, 2023 and 2,676 on May 15, 2024. For the 2020 PBRS awards, Wesbanco issued 10,100 shares of time based restricted shares to the select officers of which 5,050 will vest on May 27, 2024 and the remaining 5,050 will vest on May 27, 2025. On February 25, 2021, the Incentive Plan was amended to adjust the performance goal to 75 % and approve a pro-rata award based on the achievement between 75 % through 99 %, as the award will be prorated to the percentage achieved. Dividends accrue on the restricted shares once the performance objective is achieved and then are converted into additional shares of restricted stock on the date the cash dividend would have otherwise been paid, but do not vest until the related grant of the restricted shares complete their vesting. Voting rights accrue upon achievement of the performance objective. Compensation expense relating to all restricted stock was $ 5.0 million, $ 5.6 million and $ 4.6 million in 2022, 2021 and 2020, respectively. As of December 31, 2022 , the total unrecognized compensation expense related to non-vested restricted stock grants totaled $ 8.4 million, with a weighted average expense recognition period of 1.3 years remaining. The following table shows the activity for the Restricted Stock component of the Incentive Plan: For the Year Ended December 31, 2022 Restricted Weighted Non-vested at January 1, 2022 504,868 $ 29.42 Granted during the year 201,147 32.33 Vested during the year ( 127,532 ) 38.12 Forfeited or expired during the year ( 900 ) 34.04 Dividend reinvestment 19,197 33.83 Non-vested at end of the year 596,780 $ 28.67 Total Shareholder Return Plan On November 18, 2015, Wesbanco’s Compensation Committee adopted Administrative Rules for a Total Shareholder Return Plan (“TSRP”). The TSRP measures the TSR on Wesbanco common stock over a three-year measurement period relative to the return of an established peer group of publicly traded companies over the same performance period. The award is determined at the end of the three-year period if the TSR of Wesbanco common stock is equal to or greater than the 50th percentile of the TSR of the peer group. The number of shares to be earned by the participant shall be 200 % of the grant-date award if the TSR of Wesbanco common stock is equal to or greater than the 75th percentile of the TSR of the peer group. Upon achieving the market-based metric, shares determined to be earned by the participant become service-based and vest in three equal annual installments. Voting rights accrue at such time as well. Wesbanco granted 12,000 TSRP shares in 2022 for the performance period beginning January 1, 2022 and ending December 31, 2024 to certain executive officers. The fair value of the market-based awards is based on a Monte-Carlo Simulation valuation of our common stock and our peers’ common stock as of the grant date. Based on the calculation of shareholder return over the measurement period beginning January 1, 2020 and ending December 31, 2022 , Wesbanco stock performance measured at the 55th percentile when compared to peer calculations of shareholder return, which exceeds the target of the 50th percentile. Therefore, in the first quarter of 2023, approximately 14,640 shares relating to the 2020 TSR grant will be issued as service-based shares since the share awards are based on the pro-rata between the 50th percentile and the 75th percentile. These shares will vest in three installments of 4,880 shares in 2023, 2024 and 2025. Compensation expense relating to the TSR plans was $ 0.2 million, $ 0.4 million and $ 0.4 million in 2022, 2021 and 2020, respectively. The grant date fair value of the 2022 TSR award was $ 36.51 per share. At December 31, 2022 , the total unrecognized compensation expense related to non-vested TSR awards totaled $ 0.5 million with a weighted average expense recognition period of 2.1 years remaining.

Income Tax Disclosure [Abstract]
Income Taxes	NOT E 15. INCOME TAXES On March 27, 2020, the CARES Act was signed into law. The Act provided for the opportunity to carryback certain federal net operating losses up to five years . Wesbanco’s net operating losses had previously been recorded at the current statutory rate of 21 %. As a result of the CARES Act, Wesbanco recorded an income tax benefit of $ 0.2 million in 2020 in recognition of the rate differential between the current statutory rate and the rate in effect for which year the net operating loss will be carried back. Reconciliation from the federal statutory income tax rate to the effective tax rate is as follows: For the Years Ended December 31, 2022 2021 2020 Federal statutory tax rate 21.0 % 21.0 % 21.0 % Net tax-exempt interest income on securities and loans of state and ( 2.6 %) ( 1.8 %) ( 4.2 %) State income taxes, net of federal tax effect 3.1 % 2.3 % 1.9 % Bank-owned life insurance ( 1.0 %) ( 0.6 %) ( 1.1 %) General business credits ( 3.0 %) ( 1.9 %) ( 3.7 %) All other—net 1.2 % 0.7 % 2.0 % Effective tax rate 18.7 % 19.7 % 15.9 % The provision for income taxes applicable to income before taxes consists of the following: For the Years Ended December 31, (in thousands) 2022 2021 2020 Current: Federal $ 31,560 $ 33,042 $ 27,924 State 8,239 7,655 5,629 Deferred: Federal 3,560 17,679 ( 8,418 ) State 929 1,213 ( 2,100 ) Total $ 44,288 $ 59,589 $ 23,035 The following income tax amounts were recorded in shareholders’ equity as elements of other comprehensive income: (in thousands) 2022 2021 2020 Securities and defined benefit pension plan unrecognized items $ ( 82,295 ) $ ( 11,322 ) $ 9,730 Deferred tax assets and liabilities consist of the following: December 31, (in thousands) 2022 2021 2020 Deferred tax assets: Allowance for credit losses $ 28,535 $ 29,208 $ 44,859 Compensation and benefits — 1,154 6,894 Security gains 1,472 1,565 2,113 Non-accrual interest income 848 766 1,135 Partnership adjustments 338 — — Net operating loss carryforwards 5,685 6,480 5,472 Fair value adjustments on securities available-for-sale 83,734 1,484 — Lease accrual 10,410 11,399 13,530 Other 3,732 4,617 5,441 Gross deferred tax assets 134,754 56,673 79,444 Deferred tax liabilities: Depreciation and amortization ( 4,786 ) ( 3,748 ) ( 3,414 ) Accretion on securities ( 383 ) ( 251 ) ( 274 ) Deferred fees and costs ( 3,289 ) ( 2,368 ) ( 3,018 ) Purchase accounting adjustments ( 9,594 ) ( 9,996 ) ( 8,669 ) Compensation and benefits ( 47 ) — — Fair value adjustments on securities available-for-sale — — ( 14,865 ) Partnership adjustments — ( 127 ) ( 555 ) Lease - right of use assets ( 9,391 ) ( 10,342 ) ( 12,438 ) Other ( 763 ) ( 1,144 ) ( 168 ) Gross deferred tax liabilities ( 28,253 ) ( 27,976 ) ( 43,401 ) Net deferred tax assets $ 106,501 $ 28,697 $ 36,043 No valuation allowance was established for any deferred tax assets, since management believes that deferred tax assets are likely to be realized through future reversals of existing taxable temporary differences and future taxable income. As a result of the acquisition of YCB in 2016 and OLBK in 2019, Wesbanco has federal net operating loss (“NOL”) carryforwards of $ 22.4 million, which expire beginning in 2034 and 2037 ; respectively. Wesbanco has Maryland NOL carryforwards of $ 4.6 million, which begin expiring in 2029 . Wesbanco has Kentucky NOL carryforwards of $ 23.1 million, which begin expiring in 2028 . The use of the federal NOL and other carryforwards are limited by Internal Revenue Code Section 382, but they are currently expected to be utilized before their respective expiration dates. As a result of the previous acquisitions of YCB, ESB Financial Corporation, Fidelity Bancorp, Inc., Western Ohio Financial Corporation, Winton Financial Corporation and Oak Hill Financial, Inc., retained earnings at both December 31, 2022 and 2021 included $ 45.9 million of qualifying and non-qualifying tax bad debt reserves existing as of December 31, 1987, upon which no provision for income taxes has been recorded. The related amount of unrecognized deferred tax liability is $ 10.5 million for 2022 and $ 10.8 million for 2021. If this portion of retained earnings is used in the future for any purpose other than to absorb bad debts, it would be added to future taxable income. Federal and state income taxes applicable to securities transactions totaled ($ 0.4 ) million, $ 0.2 million and $ 1.0 million for the years ended December 31, 2022, 2021 and 2020, respectively. Wesbanco had $ 0.2 million of unrecognized tax benefits and interest as of both December 31, 2022 and 2021, respectively. As of December 31, 2022 , $ 0.2 million of these tax benefits would affect the effective tax rate if recognized. At December 31, 2022 and December 31, 2021, accrued interest related to uncertain tax positions was immaterial. Wesbanco provides for interest and penalties related to uncertain tax positions as part of its provision for federal and state income taxes. Wesbanco is subject to U.S. federal income tax as well as to tax in various state income tax jurisdictions. Wesbanco and its prior acquired companies are no longer subject to any income tax examinations for years prior to 2019 . Unrecognized Tax Benefits A reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and the federal income tax benefit of unrecognized state tax benefits) is as follows: For the Years Ended December 31, (in thousands) 2022 2021 2020 Balance at beginning of year $ 226 $ 324 $ 434 Additions based on tax positions related to the current year — 3 — Reductions due to the statute of limitations ( 68 ) ( 101 ) ( 110 ) Balance at end of year $ 158 $ 226 $ 324

Fair Value Measurement

Fair Value Measurement	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement	NO TE 16. FAIR VALUE MEASUREMENT Fair value estimates are based on quoted market prices, if available, quoted market prices of similar assets or liabilities, or the present value of expected future cash flows and other valuation techniques. These valuations are significantly affected by discount rates, cash flow assumptions, and risk assumptions used. Therefore, fair value estimates may not be substantiated by comparison to independent markets and are not intended to reflect the proceeds that may be realizable in an immediate settlement of the instruments. Fair value is determined at one point in time and is not representative of future value. These amounts do not reflect the total value of a going concern organization. Management does not have the intention to dispose of a significant portion of its assets and liabilities, and therefore the unrealized gains or losses should not be interpreted as a forecast of future earnings and cash flows. The following is a discussion of assets and liabilities measured at fair value on a recurring basis and valuation techniques applied: Investment securities: The fair value of investment securities which are measured on a recurring basis are determined primarily by obtaining quoted prices on nationally recognized securities exchanges or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other similar securities. These securities are classified within level 1 or 2 in the fair value hierarchy. Positions that are not traded in active markets for which valuations are generated using assumptions not observable in the market or management’s best estimate are classified within level 3 of the fair value hierarchy. This includes certain specific municipal debt issues for which the credit quality and discount rate must be estimated. Loans held for sale: Loans held for sale are carried, in aggregate, at fair value as Wesbanco previously elected the fair value option. The use of a valuation model using quoted prices of similar instruments are significant observable inputs in arriving at the fair value and therefore loans held for sale are classified within level 2 of the fair value hierarchy. Derivatives: Wesbanco enters into interest rate swap agreements with qualifying commercial customers to meet their financing, interest rate and other risk management needs. These agreements provide the customer the ability to convert from variable to fixed interest rates. The credit risk associated with derivatives executed with customers is essentially the same as that involved in extending loans and is subject to normal credit policies and monitoring. Those interest rate swaps are economically hedged by offsetting interest rate swaps that Wesbanco executes with derivative counterparties in order to offset its exposure on the fixed components of the customer interest rate swap agreements. The interest rate swap agreement with the loan customer and with the counterparty is reported at fair value in other assets and other liabilities on the consolidated balance sheets with any resulting gain or loss recorded in current period earnings within other income. Wesbanco enters into forward TBA contracts to manage the interest rate risk between the loan commitments to the customer and the closing of the loan for loans that will be sold on a mandatory basis to secondary market investors. The forward TBA contract is reported at fair value in other assets and other liabilities on the consolidated balance sheets with any resulting gain or loss recorded in current period earnings as mortgage banking income. Wesbanco determines the fair value for derivatives using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. Wesbanco incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. We may be required from time to time to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of lower of cost or market accounting or write-downs of individual assets and liabilities. Collateral dependent loans: Collateral dependent loans are carried at the amortized cost basis less the specific allowance calculated in accordance with CECL. Collateral dependent loans are calculated using a cost basis or collateral value approach. Other real estate owned and repossessed assets: Other real estate owned and repossessed assets are carried at the lower of the investment in the assets or the fair value of the assets less estimated selling costs. The use of independent appraisals and management’s best judgment are significant inputs in arriving at the fair value measure of the underlying collateral. Therefore, other real estate owned and repossessed assets are classified within level 3 of the fair value hierarchy. The fair value amounts presented in the table below are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statements of financial position. The following tables set forth Wesbanco’s financial assets and liabilities that were accounted for at fair value on a recurring and nonrecurring basis by level within the fair value hierarchy as of December 31, 2022 and December 31, 2021: December 31, 2022 Fair Value Measurements Using: (in thousands) December 31, 2022 Quoted Prices in Significant Other Significant Recurring fair value measurements Equity securities $ 11,506 $ 11,506 $ — $ — Available-for-sale debt securities: U.S. Government sponsored entities and agencies 225,970 — 225,970 — Residential mortgage-backed securities and collateralized 1,846,053 — 1,846,053 — Commercial mortgage-backed securities and collateralized 349,731 — 349,731 — Obligations of state and political subdivisions 92,228 — 91,049 1,179 Corporate debt securities 15,158 — 15,158 — Total available-for-sale debt securities $ 2,529,140 $ — $ 2,527,961 $ 1,179 Loans held for sale 8,249 — 8,249 — Other assets—interest rate derivatives agreements 75,840 — 75,840 — Total assets recurring fair value measurements $ 2,624,735 $ 11,506 $ 2,612,050 $ 1,179 Other liabilities—interest rate derivatives agreements 74,683 — 74,683 — Total liabilities recurring fair value measurements $ 74,683 $ — $ 74,683 $ — Nonrecurring fair value measurements Collateral dependent loans $ 878 $ — $ — $ 878 Other real estate owned and repossessed assets 1,486 — — 1,486 Total nonrecurring fair value measurements $ 2,364 $ — $ — $ 2,364 December 31, 2021 Fair Value Measurements Using: (in thousands) December 31, 2021 Quoted Prices in Significant Other Significant Recurring fair value measurements Equity securities $ 13,466 $ 13,466 $ — $ — Available-for-sale debt securities: U.S. Government sponsored entities and agencies 236,978 — 236,978 — Residential mortgage-backed securities and collateralized 2,285,213 — 2,285,213 — Commercial mortgage-backed securities and collateralized 367,493 — 367,493 — Obligations of state and political subdivisions 106,340 — 104,847 1,493 Corporate debt securities 17,438 — 17,438 — Total available-for-sale debt securities $ 3,013,462 $ — $ 3,011,969 $ 1,493 Loans held for sale 25,277 — 25,277 — Other assets—interest rate derivatives agreements 24,867 — 24,867 — Total assets recurring fair value measurements $ 3,077,072 $ 13,466 $ 3,062,113 $ 1,493 Other liabilities—interest rate derivatives agreements 26,388 — 26,388 — Total liabilities recurring fair value measurements $ 26,388 $ — $ 26,388 $ — Nonrecurring fair value measurements Collateral dependent loans $ 13,558 $ — $ — $ 13,558 Other real estate owned and repossessed assets — — — — Total nonrecurring fair value measurements $ 13,558 $ — $ — $ 13,558 Wesbanco’s policy is to recognize transfers between levels as of the actual date of the event or change in circumstances that caused the transfer.

Held-to-maturity debt securities: Fair values for debt securities held-to-maturity are determined in the same manner as investment securities, which are described above. Net loans: Fair values for loans are estimated using a discounted cash flow methodology. The discount rates take into account interest rates currently being offered to customers for loans with similar terms, the credit risk associated with the loan and other market factors, including liquidity. Wesbanco believes the discount rates are consistent with transactions occurring in the marketplace for both performing and distressed loan types. The carrying value is net of the allowance for loan losses and other associated premiums and discounts. Due to the significant judgment involved in evaluating credit quality, loans are classified within level 3 of the fair value hierarchy. Accrued interest receivable: The carrying amount of accrued interest receivable approximates its fair value . Deposits: The carrying amount is considered a reasonable estimate of fair value for demand, savings and other variable rate deposit accounts. The fair value of fixed maturity certificates of deposit is estimated by a discounted cash flow method using rates currently offered for deposits of similar remaining maturities. Federal Home Loan Bank borrowings: The fair value of FHLB borrowings is based on rates currently available to Wesbanco for borrowings with similar terms and remaining maturities. Other borrowings: The carrying amount of federal funds purchased and overnight sweep accounts generally approximate fair value. Other repurchase agreements are based on quoted market prices if available. If market prices are not available, for certain fixed and adjustable rate repurchase agreements, then quoted market prices of similar instruments are used. Subordinated debt and junior subordinated debt: The fair value of subordinated debt is estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements. Due to the pooled nature of junior subordinated debt owed to unconsolidated subsidiary trusts, which are not actively traded, estimated fair value is based on recent similar transactions of single-issuer trust preferred securities. Accrued interest payable: The carrying amount of accrued interest payable approximates its fair value. Off-balance sheet financial instruments: Off-balance sheet financial instruments consist of commitments to extend credit, including letters of credit. Fair values for commitments to extend credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present credit standing of the counterparties. The estimated fair value of the commitments to extend credit and letters of credit are insignificant and therefore are not presented in the above tables.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	NO TE 18. COMMITMENTS AND CONTINGENT LIABILITIES Commitments— In the normal course of business, Wesbanco offers off-balance sheet credit arrangements to enable its customers to meet their financing objectives. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements. Wesbanco’s exposure to credit losses in the event of non-performance by the other parties to the financial instruments for commitments to extend credit and standby letters of credit is limited to the contractual amount of those instruments. Wesbanco uses the same credit policies in making commitments and conditional obligations as for all other lending. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The allowance for credit losses associated with commitments was $ 8.4 million and $ 7.8 million as of December 31, 2022 and 2021, respectively, and is included in other liabilities on the Consolidated Balance Sheets. Letters of credit are conditional commitments issued by banks to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including normal business activities, bond financing and similar transactions. Letters of credit are considered guarantees. The liability associated with letters of credit was $ 0.2 million as of December 31, 2022 and 2021. Contingent obligations to purchase loans funded by other entities include affordable housing plan guarantees, credit card guarantees, loans sold with recourse as well as obligations to the FHLB. Affordable housing plan guarantees are performance guarantees for various building project loans. The guarantee amortizes as the loan balances decrease. Credit card guarantees are credit card balances not owned by Wesbanco, whereby the Bank guarantees the performance of the cardholder. The following table presents total commitments to extend credit, guarantees and various letters of credit outstanding: December 31, (in thousands) 2022 2021 Lines of credit $ 3,806,398 $ 2,954,147 Loans approved but not closed 398,204 472,810 Overdraft limits 380,143 370,439 Letters of credit 30,362 29,017 Contingent obligations and other guarantees 30,782 68,235 Contingent Liabilities— Wesbanco is a party to various legal and administrative proceedings and claims. While any litigation contains an element of uncertainty, management does not believe that a material loss related to such proceedings or claims pending or known to be threatened is reasonably possible.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Wesbanco Bank Community Development Corporation	NO TE 19. WESBANCO BANK COMMUNITY DEVELOPMENT CORPORATION Wesbanco Bank Community Development Corporation (“WBCDC”), a consolidated subsidiary of Wesbanco Bank, is a Certified Development Entity (“CDE”) with $ 125.0 million of New Markets Tax Credits (“NMTC”) all of which had been invested in WBCDC at December 31, 2022 . The NMTC program is administered by the Community Development Financial Institutions Fund of the U.S. Treasury and is aimed at stimulating economic and community development and job creation in low-income communities. The program provides federal tax credits to investors who make qualified equity investments (“QEIs”) in a CDE. The CDE is required to invest the proceeds of each QEI in low-income communities, which are generally defined as those census tracts with poverty rates greater than 20 % and/or median family incomes that are less than or equal to 80 % of the area median family income. The credit provided to the investor totals 39 % of each QEI in a CDE and is claimed over a seven-year credit allowance period. In each of the first three years, the investor receives a credit equal to 5 % of the total amount the investor paid to the CDE for each QEI. For each of the remaining four years, the investor receives a credit equal to 6 % of the total amount the investor paid to the CDE for each QEI. As of December 31, 2022 , Wesbanco has received $ 32.8 million in tax credits over the seven-year credit allowance periods for its $ 125.0 million NMTC authority invested in WBCDC. Wesbanco is eligible to receive an additional $ 16.0 million in tax credits with respect to aggregate QEI amounts invested over their remaining credit allowance period. Wesbanco Bank recognized $ 3.5 million, $ 2.6 million and $ 2.0 million in NMTC in its income tax provision for the years ended December 31, 2022, 2021 and 2020, respectively. These tax credits are subject to certain general business tax credit limitations and are therefore limited in deductibility on Wesbanco’s federal income tax return. As of December 31, 2022 , no prior NMTC has been carried forward to future tax years. The NMTC claimed by Wesbanco Bank with respect to each QEI remain subject to recapture over each QEI’s credit allowance period upon the occurrence of any of the following: • if less than substantially all (generally defined as 85 %) of the QEI proceeds are not used by WBCDC to make qualified low-income community investments; • WBCDC ceases to be a CDE; or • WBCDC redeems its QEI investment prior to the end of the current credit allowance periods. As of December 31, 2022, 2021 and 2020, none of the above recapture events had occurred, nor in the opinion of management are such events anticipated to occur in the foreseeable future. Approximately half of the tax credits are no longer subject to recapture. For the years ended December 31, 2022 and 2021, respectively, WBCDC recognized net (losses) gains of ($ 1.0 ) million and $ 3.8 million on an investment that it made in a start-up firm more than ten years ago that was acquired in 2021 by a public company. This gain is reported on the Consolidated Income Statements within net gain (loss) on other real estate owned and other assets.

Banking and Thrift, Other Disclosure [Abstract]
Regulatory Matters	NO TE 21. REGULATORY MATTERS The Federal Reserve Bank is the primary regulator for the parent company, Wesbanco. Wesbanco Bank is a state non-member bank jointly regulated by the FDIC and the West Virginia Division of Financial Institutions. Wesbanco is a legal entity separate and distinct from its subsidiaries and is dependent upon dividends from its subsidiary bank, Wesbanco Bank, to provide funds for the payment of dividends to shareholders, fund its current stock repurchase plan and to provide for other cash requirements. The payment of dividends by Wesbanco Bank to Wesbanco is subject to state and federal banking regulations. Under applicable law, bank regulatory agency approval is required if the total of all dividends declared by a bank in any calendar year exceeds the available retained earnings or exceeds the aggregate of the bank’s net profits (as defined by regulatory agencies) for that year and its retained net profits for the preceding two years. As of December 31, 2022, under FDIC and state of West Virginia regulations, Wesbanco could receive, without prior regulatory approval, a dividend of up t o $ 116.8 million from Wesbanco Bank. Wesbanco Bank is also required to maintain non-interest bearing reserve balances with the Federal Reserve Bank. The Bank did no t have a reserve requirement during 2022 or 2021. Additionally, Wesbanco and Wesbanco Bank are subject to various regulatory capital requirements (risk-based capital ratios) administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by the regulators that, if undertaken, could have a material adverse effect on Wesbanco’s financial results. All bank holding companies and banking subsidiaries are required to have common equity Tier 1 (“CET1”) of at least 4.5 %, core capital (“Tier 1”) of at least 6 % of risk-weighted assets, total capital of at least 8 % of risk-weighted assets, and a minimum Tier 1 leverage ratio of 4 %. Tier 1 capital consists principally of shareholders’ equity; excluding items recorded in accumulated other comprehensive income, less goodwill and other intangibles. Total capital consists of Tier 1 capital plus the allowance for loan losses, subject to limitation, and trust preferred securities. The regulations also define “well-capitalized” levels of CET1, Tier 1 risk-based capital, total risk-based capital, and Tier 1 leverage capital as 6.5 %, 8 %, 10 %, and 5 %, respectively. Wesbanco and Wesbanco Bank were categorized as “well-capitalized” under the Federal Deposit Insurance Corporation Improvement Act at December 31, 2022 and 2021. There are no conditions or events since December 31, 2022 that management believes have changed Wesbanco’s “well-capitalized” category. The Basel III capital standards, effective January 1, 2015 with a phase-in period ending January 1, 2019, establishes the minimum capital levels required under the Dodd-Frank Act, permanently grandfathers trust preferred securities as Tier 1 capital issued before May 19, 2010 for bank holding companies under $ 15 billion, and increases the capital required for certain categories of assets. A capital conservation buffer is also added to minimum capital standards that is required to be met to avoid restrictions on dividends, share repurchases, certain incentives and other restrictions. Including this capital conservation buffer, minimum levels of CET1, Tier 1 risk-based capital and total risk-based capital are defined as 7.0 %, 8.5 % and 10.5 %, respectively. Wesbanco currently has $ 133.5 million in junior subordinated debt in its Consolidated Balance Sheets presented as a separate category of long-term debt. For regulatory purposes, trust preferred securities totaling $ 130.0 million, issued by unconsolidated trust subsidiaries of Wesbanco underlying such junior subordinated debt, are considered Tier 2 capital in accordance with current regulatory reporting requirements, as Wesbanco had total consolidated assets above $ 15 billion as of December 31, 2022 and 2021. Also, in March of 2022, Wesbanco completed the issuance of $ 150.0 million in aggregate principal amount of subordinated debentures. The subordinated debentures have a fixed rate of 3.75 % for the first five years and a floating rate for the next five years at Three Month SOFR plus a spread of 1.787 %. On March 26, 2020, regulators issued interim financial rule (“IFR”) “Regulatory Capital Rule: Revised Transition of the Current Expected Losses Methodology for Allowances” in response to the disrupted economic activity from the spread of COVID-19. The IFR provides financial institutions that adopt CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided by the initial two-year delay (“ five year transition”). Wesbanco adopted CECL effective January 1, 2020 and elected to implement the five year transition. Regulatory capital levels without the capital benefit at December 31, 2022 for both the Bank and Wesbanco would have continued to be greater than the amounts needed to be considered “well capitalized”, as the capital benefit approximated 17 to 24 basis points for three of the four regulatory ratios, while total risk-based capital would have been slightly higher without the transition.

Business Segments	NOT E 23. BUSINESS SEGMENTS Wesbanco operates two reportable segments: (i) Community Banking and (ii) Trust and Investment Services. Wesbanco’s community banking segment offers services traditionally offered by full-service commercial banks, including commercial demand, individual demand and time deposit accounts, as well as commercial, mortgage and individual installment loans, and certain non-traditional offerings, such as insurance and securities brokerage services. The trust and investment services segment offers trust services as well as various alternative investment products including mutual funds. The market value of assets of the trust and investment services segment was approximately $ 4.9 billion, $ 5.6 billion and $ 5.0 billion as of December 31, 2022, 2021 and 2020, respectively. These assets are held by Wesbanco, in fiduciary or agency capacities for their customers and therefore are not included as assets on Wesbanco’s Consolidated Balance Sheets.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations— Wesbanco, Inc. (“Wesbanco” or the “Company”) is a bank holding company offering a full range of financial services, including trust and investment services, mortgage banking, insurance and brokerage services. Wesbanco’s defined business segments are community banking and trust and investment services. As of December 31, 2022, Wesbanco’s banking subsidiary, Wesbanco Bank, Inc. (“Wesbanco Bank” or the “Bank”), headquartered in Wheeling, West Virginia, operates throu gh 194 branches and 188 ATM machines in West Virginia, Ohio, western Pennsylvania, Kentucky, southern Indiana and Maryland. In addition, Wesbanco operates an insurance brokerage company, Wesbanco Insurance Services, Inc., and a full service broker/dealer, Wesbanco Securities, Inc.
Use of Estimates	Use of Estimates— The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Principles of Consolidation	Principles of Consolidation— The Consolidated Financial Statements include the accounts of Wesbanco and those entities in which Wesbanco has a controlling financial interest. All intercompany balances and transactions have been eliminated in consolidation. Wesbanco determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity. A voting interest entity is an entity in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make financial and operating decisions. Wesbanco consolidates voting interest entities in which it owns all, or at least a majority (generally, greater than 50 %) of the voting interest. Variable interest entities (“VIE”) are entities that in general either do not have equity investors with voting rights or that have equity investors that do not provide sufficient financial resources for the entity to support its activities. Wesbanco uses VIEs in various legal forms to conduct normal business activities. Wesbanco reviews the structure and activities of VIEs for possible consolidation. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits of the VIE that could potentially be significant to the VIE. A VIE often holds financial assets, including loans or receivables, real estate or other property. The company with a controlling financial interest, known as the primary beneficiary, is required to consolidate the VIE. Wesbanco has eleven wholly-owned trust subsidiaries (collectively, the “Trusts”), for which it does not have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance nor the obligation to absorb losses or the right to receive a benefits from the VIE that could be potentially significant to the VIE. Accordingly, the Trusts and their net assets are not included in the Consolidated Financial Statements. However, the junior subordinated deferrable interest debentures issued by Wesbanco to the Trusts (refer to Note 10, “Subordinated Debt and Junior Subordinated Debt”) and the common stock issued by the Trusts is included in the Consolidated Balance Sheets. Wesbanco also owns non-controlling variable interests in certain limited partnerships for which it does not have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance nor the obligation to absorb losses or the right to receive a benefit from the VIE that could be potentially significant to the VIE. These VIEs are not consolidated into Wesbanco’s financial statements because Wesbanco is not considered the primary beneficiary. These investments are accounted for using the equity method of accounting and are included in other assets in the Consolidated Balance Sheets. Refer to Note 7, “Investments in Limited Partnerships” for further detail.
Business Combinations	Business Combinations— Business combinations are accounted for by applying the acquisition method. As of acquisition date, the identifiable assets acquired and liabilities assumed are measured at fair value and recognized separately from goodwill. Results of operations of the acquired entities are included in the consolidated statement of income from the date of acquisition.
Revenue Recognition	Revenue Recognition— Interest income, net securities gains (losses) and bank-owned life insurance are not in scope of ASC 606, Revenue from Contracts with Customers . For the revenue streams in scope of ASC 606 - trust fees, service charges on deposits, net securities brokerage revenue, debit card sponsorship income, payment processing fees, electronic banking fees, mortgage banking income and net gain or loss on sale of other real estate owned and other assets– there are no significant judgements related to the amount and timing of revenue recognition. Trust fees: Fees are earned over a period of time between monthly and annually, per the related fee schedule. The fees are earned ratably over the period for investment, safekeeping and other services performed by Wesbanco. The fees are accrued when earned based on the daily asset value on the last day of the quarter. In most cases, the fees are directly debited from the customer account. WesMark fees consist of investment advisory fees and shareholder service fees and are paid to Wesbanco by the WesMark mutual funds on a monthly basis for Wesbanco’s involvement with the management of the funds. Service charges on deposits: There are monthly service charges for both commercial and personal banking customers, which are earned over the month per the related fee schedule based on the customers’ deposits. There are also transaction-based fees, which are earned based on specific transactions or customer activity within the customers’ deposit accounts. These are earned at the time the transaction or customer activity occurs. The fees are debited from the customer account. Net securities brokerage revenue: Commission income is earned based on customer transactions and management of investments. The commission income from customers’ transactions is recognized when the transaction is complete and approved. Annuity commissions are earned based upon the carrier’s commission rate for the annuity product chosen by the investing customer. The commission income from the management of investments over time is earned continuously over a quarterly period. Debit card sponsorship income: The activity in this revenue stream concluded on March 31, 2021, with the sale of this program to another bank. Debit card sponsorship income was earned from Wesbanco’s sponsorship of its customers, which included independent service organizations, processors and other banks into different debit networks. For providing this service, the customers paid the bank a per transaction fee for each transaction processed through the network. In some cases, customers were also charged annual sponsorship fees and non-compliance fees as applicable. The fees were earned at the time the transaction or customer activity occurred. The fees were either directly debited from the customers' deposit accounts or were billed to the customer. Payment processing fees: Payment processing fees are earned from the bill payment and electronic funds transfer (“EFT”) services provided under the name FirstNet. The fees are derived from both the individual consumer banking transactions and from businesses or service providers through monthly billing for total transactions occurring. These fees are earned at the time the transaction or customer activity occurs. The fees are debited from the customers’ deposit accounts or charged directly to the business or service provider. Electronic banking fees: Interchange and ATM fees are earned based on customer and ATM transactions. Revenue is recognized when the transaction is settled. Mortgage banking income: Income is earned when Wesbanco-originated loans are sold to an investor on the secondary market. The investor bids on the loans. If the price is accepted, Wesbanco delivers the loan documents to the investor. Once received and approved by the investor, revenue is recognized and the loans are derecognized from the Consolidated Balance Sheet. Prior to the loans being sold, they are classified as loans held for sale. Additionally, the changes in the fair value of the loans held for sale, loan commitments and related derivatives are included in mortgage banking income and are somewhat offset by any deferred direct origination costs, such as mortgage loan officer commissions. Net gain or loss on sale of other real estate owned and other assets: Net gain or loss on other real estate owned is recorded when the property is sold to a third party and the Bank collects substantially all of the consideration to which it is entitled in exchange for the transfer of the property. Net gain or loss on other assets can include, among other things, the sale of fixed assets, the change in fair value of the underlying investments funded by Wesbanco’s Community Development Corporation (“Wesbanco CDC”) and residual income earned from the sale of Wesbanco’s debit card sponsorship program. Gains or losses are recognized upon receipt of consideration and subsequent transfer of the property for fixed asset sales. The change in fair value of Wesbanco CDC investments occurs upon the change in the underlying investments as these are accounted for utilizing the equity method, and as such, are not within the scope of ASC 606. Residual income from the sale of the debit card sponsorship program is recognized over time as per the signed agreement between Wesbanco and the buyer.
Cash and Cash Equivalents	Cash and Cash Equivalents— Cash and cash equivalents include cash and due from banks, due from banks – interest bearing and federal funds sold. Generally, federal funds are sold for one-day periods.
Securities	Securities— Equity securities: Equity securities, which include investments in various mutual funds held in grantor trusts formed in connection with the Company’s deferred compensation plan, are reported at fair value with the gains and losses included in non-interest income. Available-for-sale debt securities: Debt securities not classified as held-to-maturity are classified as available-for-sale. These securities may be sold at any time based upon management’s assessment of changes in economic or financial market conditions, interest rate or prepayment risks, liquidity considerations and other factors. These securities are stated at fair value, with the fair value adjustment, net of tax, reported as a separate component of accumulated other comprehensive income. Held-to-maturity debt securities: Securities that are purchased with the positive intent and ability to be held until their maturity are stated at cost and adjusted for amortization of premiums and accretion of discounts. Transfers of debt securities into the held-to-maturity category from the available-for-sale category are made at fair value at the date of transfer. The unrealized gain or loss at the date of transfer is retained in other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts are amortized over the remaining life of the security. Certain securities with less than 15 % of their original purchase price remaining or that have experienced measurable credit deterioration may be sold. Cost method investments: Securities that do not have readily determinable fair values and for which Wesbanco does not exercise significant influence are carried at cost. Cost method investments consist primarily of Federal Home Loan Bank (“FHLB”) stock and are included in other assets in the Consolidated Balance Sheets. Cost method investments are evaluated for impairment whenever events or circumstances suggest that their carrying value may not be recoverable. Securities acquired in acquisitions are recorded at fair value with the premium or discount derived from the fair market value adjustment recognized into interest income on a level yield basis over the remaining life of the security. Gains and losses: Net realized gains and losses on sales of securities are included in non-interest income. The cost of securities sold is based on the specific identification method. The gain or loss is determined as of the trade date. Unrealized gains and losses on available-for-sale securities are recorded through other comprehensive income. Amortization and accretion: Generally, premiums are amortized to call date and discounts are accreted to maturity, on a level yield basis. Current expected credit losses (“CECL”): The corporate and municipal bonds in Wesbanco’s held-to-maturity debt portfolio are analyzed quarterly for CECL. Wesbanco uses a database of historical financials of all corporate and municipal issuers and actual historic default and recovery rates on rated and non-rated transactions to estimate CECL on an individual security basis. The CECL calculated amount is adjusted quarterly and is recorded in an allowance for expected credit losses on the balance sheet that is deducted from the amortized cost basis of the held-to-maturity portfolio as a contra asset, with the losses recorded on the income statement within the provision for credit losses. Because Wesbanco’s held-to-maturity investments in mortgage-backed securities and collateralized mortgage obligations are all either issued by a direct governmental entity or a government-sponsored entity, there is no historical evidence supporting the establishment of a CECL reserve; therefore, Wesbanco has estimated these losses at zero , and will monitor this assumption in the future for any economical or governmental policies that could affect this assumption. Available-for-sale debt security impairment: An available-for-sale debt security is considered impaired if its fair value is less than its amortized cost basis. If Wesbanco intends to sell or will be required to sell the investment prior to recovery of cost, the entire impairment will be recognized immediately in the Consolidated Statements of Income. If Wesbanco does not intend to sell, nor is it more likely than not that it will be required to sell, impaired securities prior to the recovery of their cost, a review is conducted each quarter to determine if any portion of the impairment is due to credit losses. In estimating credit losses, Wesbanco first considers the financial condition and near-term prospects of the issuer, evaluating any credit downgrades or other indicators of a potential credit problem, the type of security, either fixed or equity, and the receipt of principal and interest according to the contractual terms. If there are no indications that the impairment is credit-related, the impairment is recognized in other comprehensive income in the Consolidated Balance Sheet. If the impairment is considered to be credit-related based on management’s review of the various factors that indicate credit impairment, the amount of credit impairment is calculated using the present value of future expected cash flows. If the present value of future expected cash flows is less than the amortized cost basis of the security, a credit loss exists and an allowance for expected credit losses is recorded, limited by the total unrealized loss on the security, and is recognized in the Consolidated Statements of Income. The non-credit portion is calculated as the difference between the total unrealized loss and the credit portion of that loss and is recognized in other comprehensive income.
Loans and Loans Held for Sale	Loans and Loans Held for Sale — Loans originated by Wesbanco are reported at the principal amount outstanding, net of unearned income including credit valuation adjustments, unamortized deferred loan fee income and loan origination costs. Interest is accrued as earned on loans except where doubt exists as to collectability, in which case accrual of income is discontinued. Loans originated and intended for sale are carried, in aggregate, at fair value. The use of a valuation model using quoted prices of similar instruments are significant observable inputs in arriving at the fair value of loans held for sale. Loan origination fees and direct costs are deferred and accreted or amortized into interest income, as an adjustment to the yield, over the life of the loan using the level yield method, or an approximation thereof. When a loan is paid off, the remaining unaccreted or unamortized net origination fees or costs are immediately recognized into income. Loans are generally placed on non-accrual when they are 90 days past due, unless the loan is well-secured and in the process of collection. Loans may be returned to accrual status when a borrower has resumed paying principal and interest for a sustained period of at least six months and Wesbanco is reasonably assured of collecting the remaining contractual principal and interest. Loans are returned to accrual status at an amount equal to the principal balance of the loan at the time of non-accrual status less any payments applied to principal during the non-accrual period. Loans are reported as a troubled debt restructuring when Wesbanco, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. Refer to the “Troubled Debt Restructurings” policy below for additional detail. A loan is considered non-performing, based on current information and events, if it is probable that Wesbanco will be unable to collect the payments of principal and interest when due according to the original contractual terms of the loan agreement. Non-performing loans include all non-accrual loans and troubled debt restructurings. Wesbanco recognizes interest income on non-accrual loans on the cash basis only if recovery of principal is reasonably assured. Consumer loans are charged down to the net realizable value at 120 days past due for closed-end loans and 180 days past due for open-end revolving lines of credit. Residential real estate loans are charged down to the net realizable value of the collateral at 180 days past due. Commercial loans are charged down to the net realizable value when it is determined that Wesbanco will be unable to collect the principal amount in full. Loans are reclassified to other assets at the net realizable value when foreclosure or repossession of the collateral occurs. Refer to the “Other Real Estate Owned and Repossessed Assets” policy below for additional detail.
Troubled Debt Restructurings ("TDR")	Troubled Debt Restructurings (“TDR”)— A restructuring of a loan constitutes a TDR if the creditor, for economic or legal reasons related to the debtor's financial difficulties, grants a concession to the debtor that it would not otherwise consider. The determination of whether a concession has been granted includes an evaluation of the debtor’s ability to access funds at a market rate for debt with similar risk characteristics and among other things, the significance of the modification relative to unpaid principal or collateral value of the debt, and/or the significance of a delay in the timing of payments relative to the frequency of payments, original maturity date, or the expected duration of the loan. The most common concessions granted generally include one or more modifications to the terms of the debt such as a reduction in the interest rate below the prevailing market rate for the remaining life of the debt, an extension of the maturity date at an interest rate lower than the prevailing market rate for new debt with similar risk, or reduction of the unpaid principal or interest. Additionally, all consumer bankruptcies are considered TDR; all TDRs are considered nonperforming loans. 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 restructuring 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 TDRs. 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. TDRs on accrual status generally remain on accrual as long as they continue to perform in accordance with their modified terms. TDRs may also be placed on non-accrual if they do not perform in accordance with the restructured terms. Loans may be removed from TDR status after they have performed according to the renegotiated terms for a period of time if the interest rate under the modified terms is at or above market, is restructured or refinanced at market or if the loan returns to its original terms.
Acquired Loans	Acquired Loans— Loans acquired in connection with acquisitions are recorded at their acquisition-date fair value with no carryover of related allowance for credit losses. Acquired loans are classified into two categories; purchased financial instruments with more than insignificant credit deterioration (“PCD”) loans, and loans with insignificant credit deterioration (“non-PCD”). PCD loans are defined as a loan or group of loans that have experienced more than insignificant credit deterioration since origination. Non-PCD loans will have an allowance established on acquisition date, which is recognized in the current period provision for credit losses. For PCD loans, an allowance is recognized on day 1 by adding it to the fair value of the loan, which is the “Day 1 amortized cost”. There is no credit loss expense recognized on PCD loans because the initial allowance is established by grossing-up the amortized cost of the PCD loan. Determining the fair value of the acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Management considers a number of factors in evaluating the acquisition-date fair value including the remaining life of the acquired loans, delinquency status, estimated prepayments, payment options and other loan features, internal risk grade, estimated value of the underlying collateral and interest rate environment. PCD loans are accounted for in accordance with Accounting Standards Codification (“ASC”) 326-20, Financial Instruments – Credit Losses – Measure at Amortized Cost , if, at acquisition, the loan or pool of loans has experienced more-than-insignificant credit deterioration since origination. At acquisition, Wesbanco considers several factors as indicators that an acquired loan or pool of loans has experienced more-than-insignificant credit deterioration. These factors include, but are not limited to, loans 30 days or more past due, loans with an internal risk grade of below average or lower, loans classified as non-accrual by the acquired institution, the materiality of the credit and loans that have been previously modified in a troubled debt restructuring. Under ASC 326-20, a group of loans with similar risk characteristics can be assessed to determine if the pool of loans is PCD. However, if a loan does not have similar risk characteristics as any other acquired loan, the loan is individually assessed to determine if it is PCD. In addition, the initial allowance related to acquired loans can be estimated for a pool of loans if the loans have similar risk characteristics. Even if the loans were individually assessed to determine if they were PCD, they can be grouped together in the initial allowance calculation if they share similar risk characteristics. Since Wesbanco uses the discounted cash flow (DCF) approach, the initial allowance calculation for PCD loans is calculated as the expected contractual cash shortfalls, discounted at the rate that equals the net present value of estimated future cash flows expected to be collected with the purchase price of the loan(s). If a PCD loan has an unfunded commitment at acquisition, the initial allowance for credit losses calculation reflects only the expected credit losses associated with the funded portion of the PCD loan. Expected credit losses associated with the unfunded commitment are included in the initial measurement of the commitment. For PCD loans, the non-credit discount or premium is allocated to individual loans as determined by the difference between the loan’s amortized cost basis and the unpaid principal balance. The non-credit premium or discount is recognized into interest income on a level yield basis over the remaining expected life of the loan. For non-PCD loans, the interest and credit discount or premium is allocated to individual loans as determined by the difference between the loan’s amortized cost basis and the unpaid principal balance. The premium or discount is recognized into interest income on a level yield basis over the remaining expected life of the loan.
Allowance for Credit Losses	Allowance for Credit Losses— The allowance for credit losses specific to loans reduces the loan portfolio to the net amount expected to be collected, representing the lifetime expected losses at the initial origination date. Similarly, an allowance for unfunded loan commitments, which is recorded in other liabilities, represents expected losses on unfunded commitments. Fluctuations in the allowance for credit losses specific to loans, the allowance for unfunded loan commitments, and the allowance for held-to-maturity debt securities are recognized in the provision for credit losses on the consolidated statement of operations. The allowance incorporates forward-looking information and applies a reversion methodology beyond the reasonable and supportable forecast. The allowance is increased by a provision charged to operating expense and reduced by charge-offs, net of recoveries. Management evaluates the appropriateness of the allowance at least quarterly. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change from period to period. The allowance for credit loss calculation specific to loans is based on the loan’s amortized cost basis, which is comprised of the unpaid principal balance of the loan, deferred loan fees (costs) and acquired premium (discount) minus any write-downs. Wesbanco made an accounting policy election to exclude accrued interest from the measurement of the allowance for credit losses because the Company has a policy in place to reverse or write-off accrued interest when a loan is placed on non-accrual, and also Wesbanco made an accounting policy election to reverse accrued interest deemed uncollectible as a reversal of interest income. However, Wesbanco is reserving, as part of the allowance for credit losses, for accrued interest on loan modifications under the CARES Act due to the nature and timing of these deferrals. The allowance for credit losses reflects the risk of loss on the loan portfolio. To appropriately measure expected credit losses, management disaggregates the loan portfolio into pools of similar risk characteristics. The Company utilizes the probability of default (“PD”) / loss given default (“LGD”) approach to calculate the expected loss for each segment, which is then discounted to net present value. PD is the probability the asset will default within a given timeframe and LGD is the percentage of the assets not expected to be collected due to default. The primary macroeconomic drivers of the quantitative model include forecasts of national unemployment and interest rate spreads. Management relies on macroeconomic forecasts obtained from various reputable sources, which may include the Federal Open Market Committee (FOMC) forecast and other publicly available forecasts from well recognized, leading economists. These forecasts can range from one to two years , depending upon the facts and circumstances of the current state of the economy, portfolio segment and management’s judgement of what can be reasonably supported. The model reversion period ranges from one to three years . The allowance for credit losses is calculated over the loan’s contractual life. For term loans, the contractual life is calculated based on the maturity date. For commercial and industrial (“C&I”) revolving loans with no stated maturity date, the contractual life is calculated based on the internal review date. For all other revolving loans, the contractual life is based on either the estimated maturity date or a default date. The contractual term does not include expected extensions, renewals or modifications unless management has a reasonable expectation as of the reporting period that Wesbanco will execute a TDR with the borrower. Management assumes a loan will become a TDR if a consumer loan has matured, has a principal balance, and has previously been partially charged-off. This assumption extends the maturity of these loans to six months beyond maturity date. The loan portfolio is segmented based on the risk profiles of the loans. Commercial loans are segmented between commercial real estate (“CRE”), which are collateralized by real estate, and C&I, which are typically utilized for general business purposes. CRE is further segmented between land and construction (“LCD”) and improved property, which are generally loans to purchase or refinance owner occupied or non-owner occupied investment properties. LCD loans have a unique risk that the developer or builder may not complete the project or not complete it on time or within budget. Improved property loans are reviewed for risk based on the underlying real estate property such as rental or owner income, appraisal value and other current lease terms, which affect debt service coverage and loan to value. Retail loans are a homogenous group, generally consisting of standardized products that are smaller in amount and distributed over a large number of individual borrowers. The group is segmented into three categories – residential real estate, HELOC and consumer. Contractual terms are adjusted for estimated prepayments to arrive at expected cash flows. Wesbanco models term loans with an annualized “prepayment” rate. When Wesbanco has a specific expectation of differing payment behavior for a given loan, the loan may be evaluated individually. For revolving loans that do not have a principal payment schedule, a curtailment rate is factored into the cash flow. The evaluation also considers qualitative factors such as economic trends and conditions, which includes levels of regional unemployment, real estate values and the impact on specific industries and geographical markets, changes in lending policies and underwriting standards, delinquency and other credit quality trends, concentrations of credit risk, if any, the results of internal loan reviews and examinations by bank regulatory agencies pertaining to the allowance for credit losses. Management relies on observable data from internal and external sources to the extent it is available to evaluate each of these factors and adjusts the model’s quantitative results to reflect the impact these factors may have on probable losses in the portfolio. Commercial loans, including CRE and C&I that have unique characteristics are tested individually for estimated credit losses. Specific reserves are established when appropriate for such loans based on the net present value of expected future cash flows of the loan or the estimated realizable value of the collateral, if any. Management may also adjust its assumptions to account for differences between expected and actual losses from period to period. The variability of management’s assumptions could alter the level of the allowance for credit losses and may have a material impact on future results of operations and financial condition. The loss estimation models and methods used to determine the allowance for credit losses are continually refined and enhanced.
Premises and Equipment	Premises and Equipment— Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the estimated economic useful lives of the leased assets or the remaining terms of the underlying leases. Useful lives range from 3 to 10 years for furniture and equipment, 15 to 39 years for buildings and building improvements, and 15 years for land improvements. Maintenance and repairs are expensed as incurred while major improvements that extend the useful life of an asset are capitalized and depreciated over the estimated remaining useful life of the asset. Operating leases are recorded as a right of use (“ROU”) asset and operating lease liability, included in premises and equipment, net and other liabilities, respectively. Operating lease ROU assets represent the right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate at the lease commencement date. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded primarily in net occupancy expense in the consolidated statements of comprehensive income.
Other Real Estate Owned and Repossessed Assets	Other Real Estate Owned and Repossessed Assets— Other real estate owned and repossessed assets, which are considered available-for-sale and are reported in other assets, are carried at the lower of cost or their estimated current fair value, less estimated costs to sell. Other real estate owned consists primarily of properties acquired through, or in lieu of, foreclosure. Repossessed collateral primarily consists of automobiles and other types of collateral acquired to satisfy defaulted consumer loans. Subsequent declines in fair value, if any, income and expense associated with the management of the collateral, and gains or losses on the disposition of these assets are recognized in the Consolidated Statements of Income in non-interest income. Refer to Note 13, “Revenue Recognition” for further detail.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets— Wesbanco accounts for business combinations using the acquisition method of accounting. Accordingly, the identifiable assets acquired, the liabilities assumed, and any non-controlling interest of an acquired business are recorded at their estimated fair values as of the date of acquisition with any excess of the cost of the acquisition over the fair value recorded as goodwill. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Goodwill is not amortized but is evaluated for impairment annually, or more often if events or circumstances indicate it may be impaired. Finite-lived intangible assets, which consist primarily of core deposit and customer list intangibles (long-term customer-relationship intangible assets) are amortized using straight-line and accelerated methods over their weighted-average estimated useful lives, ranging from ten to sixteen years in total, and are tested for impairment whenever events or circumstances indicate that their carrying amount may not be recoverable. Non-compete agreements are recognized in other assets on the balance sheet and are amortized on a straight-line basis over the life of the respective agreements, ranging from one to four years . Goodwill is evaluated for impairment by either assessing qualitative factors to determine whether it is necessary to perform the goodwill impairment test, or Wesbanco may elect to perform a quantitative goodwill impairment test. Under the qualitative assessment, Wesbanco assesses qualitative factors to determine whether it is more likely than not that the fair value of its reporting units are less than their carrying amounts, including goodwill. If it is more likely than not, the goodwill impairment test is used to identify potential goodwill impairment and measure the amount of a goodwill impairment loss to be recognized, if any. The estimated fair value of each reporting unit is compared to its carrying value, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, the goodwill of that reporting unit is not considered impaired, and no impairment loss is recognized. However, if the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized based on the excess of a reporting unit’s carrying value over its fair value. Intangible assets with finite useful lives are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. An impairment loss is recognized when the carrying amount of an intangible asset with a finite useful life is not recoverable from its undiscounted cash flows and is measured as the difference between the carrying amount and the fair value of the asset. Wesbanco does no t have any indefinite-lived intangible assets.
Bank-Owned Life Insurance	Bank-Owned Life Insurance— Wesbanco has purchased life insurance policies on certain executive and other officers. Wesbanco receives the cash surrender value of each policy upon its termination or benefits are payable upon the death of the insured. These policies are recorded in the Consolidated Balance Sheets at their net cash surrender value. Changes in net cash surrender value are recognized in non-interest income in the Consolidated Statements of Income. Adjustments to cash surrender value and death benefits received, if recognized as income, are currently tax-exempt.
Interest Rate Lock Commitments	Interest Rate Lock Commitments— In order to attract potential home borrowers, Wesbanco offers interest rate lock commitments (“IRLC”) to such potential borrowers. IRLC are generally for sixty days and guarantee a specified interest rate for a loan if underwriting standards are met, but the commitment does not obligate the potential borrower to close on the loan. Accordingly, some IRLC expire prior to the funding of the related loan. For IRLC issued in connection with potential loans intended for sale, which consist primarily of originated longer-term fixed rate residential home mortgage loans that qualify for secondary market sale, the Bank enters into positions of forward month mortgage-backed securities to be announced (“TBA”) contracts on a mandatory basis or on a one-to-one forward sales contract on a best efforts basis. A mortgage loan sold on a mandatory basis to the secondary market is considered sold when the mortgage loan is funded. Wesbanco enters into TBA contracts in order to control interest rate risk during the period between the IRLC and the sale of the mortgage loan. The IRLC is executed between the mortgagee and Wesbanco, and the forward TBA contract is executed between Wesbanco and a counterparty. Both the IRLC and the forward TBA contract are considered derivatives. A mortgage loan sold on a best efforts basis is locked into a forward sales contract on the same day as the IRLC to control interest rate risk during the period between the IRLC and the sale of the mortgage loan. The IRLC is executed between the mortgagee and Wesbanco, and the forward sales contract is executed between Wesbanco and a counterparty. Both the IRLC and the forward sales contract are considered derivatives. Both types of derivatives are recorded at fair value and are not designated in a qualified hedged accounting program. The changes in fair value are recorded in current earnings within mortgage banking income in the Consolidated Statements of Income. The fair value of IRLC is the gain or loss that would be realized on the underlying loans assuming exercise of the commitments under current market rates versus the rate incorporated in the commitments, taking into consideration loans cancelled prior to closing. The fair value of forward sales contracts is based on quoted market prices. Since loans typically close before receipt of funding from an investor, they are accounted for at fair value as “Loans Held for Sale” in the Consolidated Balance Sheets.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities— Wesbanco records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether Wesbanco has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Wesbanco enters into back-to-back interest rate swaps with commercial banking customers and then with counterparties for the offsetting interest rate swap. Currently, none of Wesbanco’s derivatives are designated in qualifying hedging relationships, as the derivatives are not used to manage risks within Wesbanco’s assets or liabilities. As such, all changes in fair value of Wesbanco’s derivatives are recognized directly in earnings.
Income Taxes	Income Taxes— The provision for income taxes included in the Consolidated Statements of Income includes both federal and state income taxes and is based on income in the financial statements, rather than amounts reported on Wesbanco’s income tax returns. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases at which rates they are expected to turnaround. A test of the anticipated realizability of deferred tax assets is performed at least annually.
Fair Value	Fair Value— Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements are not adjusted for transaction costs. The ASC also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are described below: Level 1—Quoted prices in active markets for the same security that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market; Level 3—Valuation is generated from model-based techniques where one or more significant assumptions are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of discounted cash flow models and similar techniques. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
Earnings Per Common Share	Earnings Per Common Share— Basic earnings per common share (“EPS”) is calculated by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. For diluted EPS, the weighted-average number of shares for the period is increased by the number of shares, which would be issued assuming the exercise of in-the-money common stock options and any outstanding warrants. Time-based restricted stock shares are recorded as issued and outstanding upon their grant, rather than upon vesting, and therefore are included in the weighted-average shares outstanding due to voting rights granted at the time restricted stock is granted. Performance and market-based restricted stock shares are recorded as issued and outstanding upon their achieving the required performance or market factors. These restricted shares are included in the number of shares outstanding for diluted EPS if their performance or market factors are expected to be achieved as of the reporting date.
Trust Assets	Trust Assets— Assets held by the Bank in fiduciary or agency capacities for its customers are not included as assets in the Consolidated Balance Sheets. Certain money market trust assets are held on deposit at the Bank and are accounted for as such.
Stock-Based Compensation	Stock-Based Compensation— Stock-based compensation awards granted, comprised of stock options, performance and time-based restricted stock, and total shareholder return (“TSR”) awards are valued at fair value and compensation cost is recognized on a straight-line basis over the requisite service or performance period of each award. For service-based awards with graded vesting schedules, compensation expense is divided among the vesting periods with each separately vested portion of the award recognized in compensation expense on a straight-line basis over the requisite service period. For performance-based awards and TSR awards, compensation expense is recognized evenly over the performance period, based on the probability of the achievements of the performance or market conditions set forth in the plans. Upon adoption of Accounting Standards Update (“ASU”) 2016-09, “Compensation-Stock Compensation (Topic 718)”, Wesbanco recognizes forfeitures as they occur rather than estimating them over the life of the award.
Defined Benefit Pension Plan	Defined Benefit Pension Plan— Wesbanco recognizes in the statement of financial position an asset for the plan’s overfunded status or a liability for the plan’s underfunded status. Wesbanco recognizes fluctuations in the funded status in the year in which the changes occur through other comprehensive income. Plan assets are determined based on fair value generally representing observable market prices. The projected benefit obligation is determined based on the present value of projected benefit distributions at an assumed discount rate. The discount rate utilized is based on a fitted yield curve approach whereby the yield curve compares the expected stream of future benefit payments for the plan to high quality corporate bonds available in the marketplace to determine an equivalent discount rate. Periodic pension expense includes service costs, interest costs based on an assumed discount rate, an expected return on plan assets based on an actuarially-derived market-related value, an assumed rate of annual compensation increase, and amortization or accretion of actuarial gains and losses as well as other actuarial assumptions. The service cost component is recognized in salaries and wages and the remaining costs are recognized in employee benefits within the Company’s Consolidated Statement of Income. Wesbanco utilizes a full yield curve approach in the estimation of service and interest components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. The plan has been closed to new entrants since August 2007; however, benefits are still earned for those plan participants with continuing employment after August 2007. Refer to Note 12, “Employee Benefit Plans” for further detail.
Post-retirement Medical Benefit Plan	Post-retirement Medical Benefit Plan— Wesbanco acquired a non-qualified supplemental retirement plan for certain key employees from Farmers Capital Bank Corp. (“FFKT”). The Plan provides lifetime medical and dental benefits upon retirement for certain employees meeting the eligibility requirement, which were amended by Wesbanco upon acquisition. Wesbanco recognizes a liability for the projected benefit obligation in the Consolidated Balance Sheets in other liabilities as this plan is unfunded until period payments are made. Wesbanco recognizes fluctuations in the projected benefit obligation through other comprehensive income. The projected benefit obligation is based on the present value of projected medical and dental obligations at an assumed discount rate. Periodic benefit expense includes service cost, interest cost based on an assumed discount rate, and amortization or accretion of actuarial gains and losses, as well as other actuarial assumptions. Refer to Note 12, “Employee Benefit Plans” for further detail.
Recent accounting pronouncements	Recent accounting pronouncements— The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below. ASU 2022-05 Financial Services – Insurance (Topic 944) In December 2022, the FASB issued ASU 2022-05, “Financial Services – Insurance (Topic 944).” The Board issued Accounting Standards Update No. 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (LDTI), in August 2018. The amendments in Update 2018-12 require that an insurance entity apply a retrospective transition method to LDTIs as of the beginning of the earliest period presented or the beginning of the prior fiscal year if early application is elected. 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. 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 Troubled Debt Restructurings ("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. ASU 2022-01 Derivatives and Hedging (Topic 815) In March 2022, the FASB issued ASU 2022-01, "Derivatives and Hedging (Topic 815)". The amendments in this ASU address several topics within ASU 2017-12, which was issued in August 2017 to improve the hedge accounting model. ASU 2022-01 expands the current last-of-layer method to allow multiple hedged layers of a single closed portfolio and renames the last-of-layer method as the portfolio layer method. Among other things, the ASU expands the scope of the portfolio layer method to include nonprepayable financial assets, provides additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method whether a single hedged layer or multiple hedge layers are designated and specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. For Wesbanco, this update was effective beginning on January 1, 2023 . The adoption of this pronouncement did no t have a material impact on the Consolidated Financial Statements. ASU 2021-08 Business Combinations (Topic 805) In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805)." The amendments in this Update require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, "Revenue Recognition." The amendments also apply to contract assets and contract liabilities from other contracts to which the provisions of Topic 606 apply, such as contract liabilities from the sale of nonfinancial assets within the scope of Subtopic 610-20, "Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets." For Wesbanco, this update was effective beginning on January 1, 2023 . The adoption of this pronouncement did no t have a material impact on the Consolidated Financial Statements. 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, and Wesbanco continues to assess the impact of adopting the new guidance on the consolidated financial statements on an ongoing basis, with no material impacts expected at this time. 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 is not expected to have a material impact on Wesbanco’s Consolidated Financial Statements.
