Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020.

Wesbanco’s interim financial statements have been prepared following the significant accounting policies disclosed in Note 1 of the Notes to the Consolidated Financial Statements of its 2020 Annual Report on Form 10-K filed with the Securities and Exchange Commission.  In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly Wesbanco’s financial position and results of operations for each of the interim periods presented. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on Wesbanco’s net income and stockholders’ equity. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year.

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

ASU 2020-04 and ASU 2021-01 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 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, 2022, and can be adopted at any time during this period. Wesbanco has not yet adopted either ASU, but has implemented a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR, and 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.

ASU 2019-12 Income Taxes (Topic 740)

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP for: (1) franchise taxes that are partially based on income; (2) transactions with a government that result in a step-up in the tax basis of goodwill; (3) separate financial statements of legal entities that are not subject to tax; and (4) enacted changes in tax laws in interim periods. For Wesbanco, this update was effective beginning January 1, 2021. The adoption of this pronouncement did not have a material impact on the financial statements.

NOTE 2. EARNINGS PER COMMON SHARE

Earnings per common share are calculated as follows:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
(unaudited, in thousands, except shares and per share amounts)	2021		2020		2021		2020

Earnings per common share - diluted	$	0.64	$	0.61	$	2.71	$	1.03

As of September 30, 2021 and 2020, respectively, 534,961 and 729,985 options to purchase shares were not included in the computation of net income per diluted share for the three months ended September 30, 2021 and 2020 because the exercise price was greater than the average market price of a common share, therefore, the effect would be antidilutive. As of September 30, 2021 and 2020, respectively, 534,961 and 536,761 options to purchase shares were not included in the computation of net income per diluted share for the nine months ended September 30, 2021 and 2020 on the same basis.

7

As of September 30, 2021, no shares related to the 2021, 2020 and 2019 total shareholder return plans were included in the calculation because the effect would be antidilutive. On the same basis, as of September 30, 2020, no shares related to the 2020, 2019 and 2018 total shareholder return plans were included in the calculation.

In addition, performance-based restricted stock totaling 61,267 and 27,371 shares were estimated to be awarded as of September 30, 2021 and September 30, 2020, respectively, and are included in the diluted calculation for both the three and nine months ended.

(1) Total held-to-maturity debt securities are presented on the balance sheet net of their allowance for credit losses totaling $0.3 million at September 30, 2021 and December 31, 2020, respectively.

At September 30, 2021 and December 31, 2020, 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 $10.5 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 $13.5 million and $13.0 million at September 30, 2021 and December 31, 2020, respectively.

Securities with an aggregate fair value of $2.0 billion and $1.8 billion at September 30, 2021 and December 31, 2020, respectively, were pledged as security for public and trust funds, and securities sold under agreements to repurchase. Proceeds from the sale of available-for-sale securities were $0 and $226.1 million for the nine months ended September 30, 2021 and 2020, respectively.  Net unrealized gains on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of September 30, 2021 and December 31, 2020 were $18.5 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 three and nine months ended September 30, 2021 and 2020, respectively.  All gains and losses presented in the table below are included in the net securities gains 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.

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 $7.1 million and $5.3 million as of September 30, 2021 and December 31, 2020, 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.

Unrealized losses on debt securities in the table above represents 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

10

sell, nor is it more likely than not that it will be required to sell, loss position securities prior to recovery of their cost; 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 Federal Home Loan Bank (“FHLB”) of Pittsburgh stock totaling $17.0 million and $34.0 million at September 30, 2021 and December 31, 2020, 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.

NOTE 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 fee income was $1.7 million and $6.2 million at September 30, 2021 and December 31, 2020, respectively.  At September 30, 2021 and December 31, 2020, respectively, the balance also included $10.4 million and $13.8 million of net deferred fee income from SBA Payroll Protection Program (“PPP”) loans. The un-accreted discount on purchased loans from acquisitions was $28.9 million at September 30, 2021 and $39.4 million at December 31, 2020.

The allowance for credit losses under the current expected credit losses methodology (“CECL”) is calculated utilizing the probability of default (“PD”) / loss given default (“LGD”), which is then discounted to net present value. PD is the probability the asset will default within a given time frame and LGD is the percentage of the asset not expected to be collected due to default. The primary macroeconomic drivers of the quantitative model include forecasts of national unemployment and interest rates, as well as modeling adjustments for changes in prepayment speeds, loan risk grades, portfolio mix, concentrations and loan growth. For the calculation as of September 30, 2021, the one-year forecast was based upon a blended rate from two nationally-recognized published economic forecasts through September 30, 2021, and is primarily driven by the national unemployment and interest rate spread forecasts. Wesbanco’s blended forecast of national unemployment, at quarter end, was projected to peak at 4.7% in the fourth quarter, and subsequently decrease to an average of 4.0% over the remainder of the forecast period. The calculation utilized a one-year reversion period back to the Company’s historical loss rate by loan classification.  Included in the qualitative factors were COVID-19 pandemic factors related to the transient credit risk not included within the quantitative model calculation, adjusted to Wesbanco’s regional footprint, deferred interest on modified loans, and hospitality industry concentration.  As of September 30, 2021, accrued interest receivable for loans was $48.1 million. 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 $0.1 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 September 30, 2021, accrued interest receivable related to COVID-19 loan modifications as permitted under the CARES Act was $23.1 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.  

Commercial and industrial (“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.

13

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.

Residential real estate, home equity and consumer loans are not assigned internal risk grades other than as required by regulatory guidelines that are based primarily on the age of past due loans.  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 was $29.4 million at September 30, 2021 and $27.7 million at December 31, 2020, of which $6.2 million and $4.1 million were accruing, for each period, respectively.  These loans are not included in the tables above.  In addition, $20.4 million and $28.7 million of unfunded commercial loan commitments, are also not included in the tables above at September 30, 2021 and December 31, 2020, respectively.

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 3,553 loans totaling $2.2 billion, of which $132.8 million remain in their deferral period as of September 30, 2021.  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.  On December 27, 2020, the Economic Aid to Hard-Hit Small Businesses, Nonprofits and Venues Act (“Economic Aid Act”) was signed into law and among other things, extended the relief granted by the CARES Act for TDRs, initially slated to end on December 31, 2020, by one year to December 31, 2021.

NOTE 5. 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 Wesbanco Bank, Inc.’s (the “Bank”) assets and liabilities are equally distributed but also have similar maturities.

Loan Swaps

Wesbanco executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies.  Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that Wesbanco executes with a third party, such that Wesbanco minimizes its net risk exposure resulting from such transactions.  As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements of ASC 815, changes in the fair value of both the customer swaps and the offsetting third-party swaps are recognized directly in earnings.  As of September 30, 2021 and December 31, 2020, Wesbanco had 130 and 112 customer interest rate swaps with an aggregate notional amount of $696.0 million and $649.9 million, respectively, related to this program.  Wesbanco recognized income for the related swap fees of $0.4 million and $0.9 million for the three months ended September 30, 2021 and 2020, respectively and $3.3 million and $7.0 million for the nine months ended September 30, 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 September 30, 2021 and December 31, 2020, Wesbanco had 14 and 12, risk participation-in agreements with an aggregate notional amount of $132.4 million and $101.1 million, respectively.  As of September 30, 2021 and December 31, 2020, Wesbanco had one risk participation-out agreement with an aggregate notional amount of $9.9 million and $10.0 million, respectively.

Mortgage Loans Held for Sale and Loan 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 loan commitment and the closing of the loan.  The total balance of forward TBA contracts entered into was $65.2 million and $183.5 million at September 30, 2021 and December 31, 2020, 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 paying 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 a qualifying hedging relationship 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 September 30, 2021 and December 31, 2020:

Credit-risk-related Contingent Features

Wesbanco has agreements with its derivative counterparties that contain a provision, which provides that if Wesbanco defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Wesbanco could also be declared in default on its derivative obligations.

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.

Wesbanco had minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral with a market value of $58.0 million as of September 30, 2021.  If Wesbanco had breached any of these provisions at September 30, 2021, 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.

NOTE 6. BENEFIT PLANS

The following table presents the net periodic pension income for Wesbanco’s Defined Benefit Pension Plan (the “Plan”) and the related components:

	For the Three Months Ended September 30,						For the Nine Months Ended September 30,
(unaudited, in thousands)	2021			2020			2021			2020
Service cost – benefits earned during year	$	630		$	574		$	1,869		$	1,710
Interest cost on projected benefit obligation		861			1,133			2,555			3,375
Expected return on plan assets		(2,825	)		(2,622	)		(8,382	)		(7,810	)
Amortization of prior service cost		(9	)		(9	)		(26	)		(27	)
Amortization of net loss		690			802			2,047			2,389
Net periodic pension income	$	(653	)	$	(122	)	$	(1,937	)	$	(363	)

The service cost of $1.9 million and $1.7 million for the nine months ended September 30, 2021 and 2020, respectively, is included in salaries and wages, and the periodic pension income of $3.8 million and $2.1 million for the nine months ended September 30, 2021 and 2020, respectively, is included in employee benefits.

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, and is not available to employees hired after such date.

A minimum required contribution of $5.2 million is due for 2021, which can be offset in whole or in part by the Plan’s $64.2 million available credit balance. Wesbanco currently does not expect to make a voluntary contribution to the Plan in 2021.

NOTE 7. 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.

23

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 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 sheet with any resulting gain or loss recorded in current period earnings as other income and other expense.

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 sheet with any resulting gain or loss recorded in current period’s 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.

Individually-evaluated loans: Individually-evaluated loans are carried at the amortized cost basis less the specific allowance calculated under CECL. Individually-evaluated loans are calculated using a cost basis approach 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, and therefore other real estate owned and repossessed assets are classified within level 3 of the fair value hierarchy.

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.  There were no significant transfers between level 1, 2 or 3 for the three and nine months ended September 30, 2021 or for the year ended December 31, 2020.  

The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which Wesbanco has utilized level 3 inputs to determine fair value:

The following methods and assumptions were used to measure the fair value of financial instruments recorded at cost on Wesbanco’s consolidated balance sheets:

Cash and due from banks:  The carrying amount for cash and due from banks is a reasonable estimate of fair value.

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.

27

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.

NOTE 8. 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.

28

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 slightly 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 per the signed agreement between Wesbanco and the buyer.

The following table summarizes the point of revenue recognition and the income recognized for each of the revenue streams for the three and nine months ended September 30, 2021 and 2020, respectively:

NOTE 10. 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 $7.3 million and $9.5 million at September 30, 2021 and December 31, 2020, 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 $0.1 million and $0.2 million as of September 30, 2021 and December 31, 2020, respectively.

Contingent obligations to purchase loans funded by other entities include credit card guarantees, loans sold with recourse as well as obligations to the FHLB.  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:

Contingent Liabilities — Wesbanco recognized $2.6 million of legal settlement costs in the third quarter in which settlement is subject to final court approval. 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.

NOTE 11. BUSINESS SEGMENTS

Wesbanco operates two reportable segments: community banking and 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 managed or held in custody by the trust and investment services segment was approximately $5.5 billion and $4.6 billion at September 30, 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.

RESULTS OF OPERATIONS

EARNINGS SUMMARY

Net income available to common shareholders for the three months ended September 30, 2021 was $41.9 million, with diluted earnings per share of $0.64, compared to $41.3 million or $0.61 per diluted share, respectively, for the third quarter of 2020.  Net income for the nine months ended September 30, 2021, was $180.5 million, with diluted earnings per share of $2.71, compared to $69.2 million or $1.03 per diluted share, respectively, for the first nine months of 2020.  Excluding after-tax restructuring and merger-related expenses (non-GAAP measure) in both periods, for the three months ended September 30, 2021, net income available to common shareholders was $45.4 million or $0.70 per diluted share, as compared to $44.2 million or $0.66 per diluted share, respectively, in the prior year quarter; and net income for the nine months ended September 30, 2021 was $185.7 million or $2.79 per diluted share compared to $76.5 million or $1.14 per diluted share in the prior year period.

(1) Non-GAAP net income excludes after-tax restructuring and merger-related expenses.  The above non-GAAP financial measures used by Wesbanco provide information useful to investors in understanding Wesbanco’s operating performance and trends, and facilitate comparisons with the performance of Wesbanco’s peers.

Net interest income decreased $5.3 million or 4.4% in the third quarter of 2021 compared to the same quarter of 2020, reflecting lower loan yields, due to repricing of existing loans and new lower rates offered in the current market environment, lower purchase accounting related accretion and lower rates on investment securities, partially offset by lower interest on deposits and borrowings.  As a result of the lower rates and a higher mix of securities versus loans to total assets, the net interest margin decreased by 23 basis points to 3.08% in the third quarter of 2021 as compared to the third quarter of 2020.  Over the same time period, the yield on earning assets decreased a total of 42 basis points and the cost of interest bearing liabilities decreased 28 basis points.  Average loan balances decreased by 8.5% from the third quarter of 2020, mainly attributable to forgiveness of SBA Payroll Protection Program (“PPP”) loans and higher levels of commercial real estate loan payoffs, while average securities increased by 41.7% over the same time period due to excess liquidity on the balance sheet from stimulus funds received by our customers. Average deposits, excluding certificates of deposit, increased 15.3% over the same time period, due mostly to stimulus deposits and increased personal savings.   Accretion from acquisitions benefited the third quarter 2021 net interest margin by 10 basis points, as compared to 18 basis points in the prior year period.  Lastly, the accretion on both existing and forgiven PPP loans positively impacted the third quarter 2021 net interest margin by a net 14 basis points as compared to two basis points for the third quarter of 2020.

Improved macroeconomic forecasts and certain qualitative factors utilized in the CECL calculation drove a net benefit of provision for credit losses and resulted in a negative provision of $1.7 million in the third quarter of 2021 as compared to a provision of $16.3 million in the third quarter of 2020.  Annualized net charge-offs as a percentage of average portfolio loans, were 0.03% and 0.00% for the third quarter of 2021 and 2020, respectively.

For the third quarter of 2021, non-interest income decreased $1.9 million or 5.4% compared to the third quarter of 2020, driven primarily by lower mortgage banking income, which decreased $3.9 million or 46.2% from the record level recorded in the prior year amount.  While mortgage loan originations remained solid during the quarter, the amount sold in the secondary market decreased from approximately 75% last year to approximately 40% in the third quarter of 2021, due to a continued effort to keep more 1-to-4 family residential mortgages on the balance sheet.  Trust fees increased $0.9 million or 13.4% from the third quarter of 2020 to the third quarter of 2021 due to market improvements and net organic growth.  Electronic banking fees increased $0.6 million or 13.5% from last year’s third quarter as we transitioned to adjusted settlement processes of a new third-party digital banking service provider.  Other income decreased $1.0 million or 19.4% due to lower loan swap-related income and the sale of the debit card sponsorship business earlier this year.

Non-interest expense, excluding restructuring and merger-related expenses in both periods, increased in the third quarter of 2021 by $3.9 million or 4.5%, to $90.2 million, compared to the third quarter of 2020.   This year-over-year increase is primarily due to $2.6 million of settlement costs from the pending resolution of a lawsuit, which are located within other operating expenses, and higher salaries expense.  Salaries and wages increased $1.2 million or 3.0% from the third quarter of 2020 to the third quarter of 2021 due to higher incentive compensation expense of $1.8 million, reflecting increased business growth and financial performance as compared to the pandemic-impacted prior year.  Equipment and software expense for the third quarter of 2021 increased $1.4 million or 22.2% year-over-year, due to increased asset size, increased usage of digital banking services and SBA PPP loan forgiveness. Offsetting these increases somewhat was a decrease in FDIC insurance expense of $0.7 million or 37.0% due to improved risk factors reducing the assessment rate.

34

During the third quarter of 2021, the effective tax rate was 19.3% as compared to 15.7% in last year’s third quarter, and the provision for income taxes increased by $3.0 million over the same time period, primarily due to higher pre-tax income heavily influenced by the negative provision for credit losses in the third quarter of 2021 as compared to the prior year’s reduced pre-tax income from a pandemic-induced higher provision for credit losses.

Net interest income, which is Wesbanco’s largest source of revenue, is the difference between interest income on earning assets, primarily loans and securities, and interest expense on liabilities, primarily deposits and short and long-term borrowings.  Net interest income is affected by the general level of, and changes in interest rates, the steepness and shape of the yield curve, changes in the amount and composition of interest earning assets and interest bearing liabilities, as well as the frequency of repricing of existing assets and liabilities. Net interest income decreased $5.3 million or 4.4% in the third quarter of 2021 compared to the third quarter of 2020, due to a 23 basis point decrease in the net interest margin to 3.08% resulting from the lower yield environment, as the yield on earning assets decreased at a faster rate than the rate on interest bearing liabilities.  For the nine months ended September 30, 2021, net interest income decreased by $12.2 million or 3.4% compared to the first nine months of 2020 for similar reasons. The net interest margin decrease was slightly mitigated by a 2.3% increase in average earning asset balances from the third quarter of 2020, primarily from a 41.7% increase in average securities, which were purchased with liquidity from stimulus-related deposits.  Also helping to mitigate the margin decrease, PPP loans contributed a total of $8.2 million in interest and fee accretion income in the third quarter of 2021.  This PPP loan income positively impacted the third quarter 2021 net interest margin by a net 14 basis points. Excluding PPP loans, portfolio loans decreased by 4.9% from September 30, 2020, due to lower new loan demand and high levels of commercial real estate loan payoffs. In addition, purchase accounting accretion decreased in the third quarter of 2021, as approximately 10 basis points of accretion from prior acquisitions was included in the third quarter 2021 net interest margin as compared to 18 basis points in the 2020 third quarter net interest margin.  Total average deposits, excluding CDs, increased in the third quarter of 2021 by $1.6 billion or 15.3% compared to the third quarter of 2020, due to stimulus deposits and higher personal savings balances.  The cost of interest bearing deposits decreased by 12 basis points and total liabilities decreased by 28 basis points from the third quarter of 2020 to the third quarter of 2021. The decrease in the cost is primarily due to aggressive rate decreases for interest bearing demand deposits, which include public funds, and lower rates for certificates of deposit, customer repurchase agreements, term Federal Home Loan Bank borrowings and junior subordinated debentures, in response to the general decrease in overall borrowing rates in the marketplace resulting from lower rates across the yield curve.  In addition, the average balance of FHLB borrowings decreased by $717.3 million or 71.3% from the third quarter of 2020, as excess liquidity was used to pay off these borrowings as they matured.

Interest income decreased $12.3 million or 9.2% in the third quarter of 2021 and $41.0 million or 10.0% in the first nine months of 2021 compared to the same periods of 2020 due to lower yields in every major earning asset category.  Earning asset yields were influenced negatively in the third quarter of 2021 compared to the third quarter of 2020 due primarily to decreases in the Federal Reserve’s federal funds rate by 150 basis points in 2020 and the continuation of the low rate environment through the current period.  Average loan balances decreased $942.8 million or 8.5% in the third quarter of 2021 compared to the third quarter of 2020, due mostly to forgiveness of PPP loans that were originated in 2020 and the first half of 2021. Loan yields decreased by 14 basis points during this same period to 4.03% due to the previously mentioned lower rate environment and its effect on the repricing of portfolio loans, as well as lower offered rates on new loans.  Loans provide the greatest impact on interest income and the yield on earning assets as they have the largest balance and the highest yield within major earning asset categories.  In the third quarter of 2021, average loans represented 67.8% of average earning assets, a decrease from 75.8% in the third quarter of 2020. As liquidity from stimulus deposits was invested, average taxable securities balances increased $1.1 billion or 51.3% from the third quarter of 2020, and represented 21.4% of total earning assets in the third quarter of 2021. Taxable securities yields decreased by 52 basis points and tax-exempt securities yields decreased by 35 basis points in the third quarter of 2021 from the third quarter of 2020. The continuing lower rate environment has resulted in the yield decrease for all securities, as calls, prepayments and maturities of legacy higher-rate securities have been replaced with purchases at lower overall market yields.  Increased prepayments on mortgage-backed securities in the lower rate environment also further reduced the taxable securities yields due to higher premium amortization. The average balance of tax-exempt securities, which have the highest yields within securities, have decreased from 22.2% of total average securities in the third quarter of 2020 to 16.8% of total average securities in the third quarter of 2021.  

35

Commercial loans with floors currently average 3.93% on approximately $2.6 billion or 35% of total commercial loans at September 30, 2021, as compared to $2.3 billion averaging 4.22% or 29% of commercial loans at December 31, 2020. Approximately 65% or $1.7 billion of these loans are currently priced at their floor, as compared to 69% or $1.6 billion at December 31, 2020. These loans typically do not adjust as rapidly from their current floor level as compared to loans without floors, due to the amount of the rate change as compared to the floor rate or next repricing date. In addition, in a declining rate environment, customers may request rates below existing contractual floors, which we may grant for competitive or other reasons.

Interest expense decreased $7.0 million or 53.3% in the third quarter of 2021 and $28.9 million or 56.6% in the first nine months of 2021 as compared to the same periods in 2020, due to decreases in the cost of all interest bearing liability categories, as management reduced certain deposit rates, and due to a decrease in the balance of outstanding FHLB borrowings. The cost of interest bearing liabilities decreased by 28 basis points from the third quarter of 2020 to 0.25% in 2021.  Interest bearing deposits increased $784.5 million or 9.6% from the third quarter of 2020, due mostly to customers’ stimulus payments.  The rate on interest bearing deposits decreased 12 basis points to 0.14% from the third quarter of 2020, primarily from aggressive decreases in rates on interest bearing public funds and certificates of deposit in response to the lower market rates, which are currently near their floors. Average non-interest bearing demand deposit balances increased from the third quarter of 2020 to the third quarter of 2021 by $462.7 million or 11.4%, and were 33.4% of total average deposits at September 30, 2021, compared to 33.1% at September 30, 2020, reflecting the previously mentioned stimulus deposits, higher personal savings balances and ongoing checking account marketing strategies. The average balance of FHLB borrowings decreased $717.3 million from the third quarter of 2020 to 2021 due to the maturity of legacy higher-rate FHLB borrowings throughout the past twelve months being redeemed with excess liquidity.  These maturities benefited the average rate paid, as it decreased by 53 basis points to 1.63% from the third quarter of 2020.  Average other borrowings combined with subordinated debt and junior subordinated debt balances decreased $251.6 million or 43.7% from the third quarter of 2020 to 2021, and their average rates paid decreased by 22 and 20 basis points, respectively, over this same time period, due primarily to decreases in LIBOR, the index upon which this variable-rate type of borrowing is priced.

The continuing low rate environment is expected to result in the core net interest margin declining a few basis points over the fourth quarter, as securities purchased toward the end of the third quarter will further negatively impact the margin. Lower anticipated earning asset yields caused by loans repricing to lower rates, rates on new loan production being lower than existing loans, security cash flows being reinvested at lower rates and decreasing purchase accounting accretion should be slightly mitigated by price reductions to deposit rates and lower wholesale funding costs.  The subordinated debt payoff late in the third quarter of 2021 and the upcoming subordinated debt payoff in November, both of which were acquired in previous acquisitions, will further help to reduce the cost of interest-bearing liabilities. In addition, Wesbanco’s participation in the PPP loan program is expected to positively contribute to net interest income and further mitigate the decreases in the net interest margin as SBA loan forgiveness occurs for qualifying customers and net deferred fees are accreted into income at the date of loan payoff. At September 30, 2021, there were $10.4 million of remaining net deferred fees from PPP loans that will accrete into interest income as loans pay down or are forgiven by the SBA.

PROVISION FOR CREDIT LOSSES – LOANS AND LOAN COMMITMENTS

The provision for credit losses – loans is the amount to be added to the allowance for credit losses – loans after net (charge-offs) recoveries have been (deducted) added to bring the allowance to a level considered appropriate to absorb lifetime expected losses for all portfolio loans.  The provision for credit losses – loan commitments is the amount to be added to the allowance for credit losses for loan commitments to bring that allowance to a level considered appropriate to absorb lifetime expected losses on unfunded loan commitments.  The provision for credit losses - loans and loan commitments decreased to ($1.7) million in the third quarter of 2021 compared to $16.3 million in the third quarter of 2020, as a result of changes in the macroeconomic forecast and certain other qualitative factors.  As of September 30, 2021, the macroeconomic forecast estimated significantly lower unemployment over the reasonable and supportable forecast period of one year, as compared to the forecast utilized during the third quarter of 2020, resulting in a decrease in the allowance for loan losses and allowance for loan commitments.  Non-performing loans were 0.40% of total loans as of September 30, 2021, increasing from 0.38% of total loans at the end of the third quarter of 2020.  Criticized and classified loans were 4.21% of total loans as of September 30, 2021, increasing from 3.25% as of September 30, 2020, primarily due to recent adjustments to the internal loan classification system, which impacted risk grades, and downgrades in the Company’s hospitality loan portfolio. Past due loans at September 30, 2021 were 0.44% of total loans, compared to 0.25% at September 30, 2020. Annualized net loan charge-offs increased to 0.01% for the nine months ended September 30, 2021 compared to 0.08% for the nine months ended September 30, 2020.  (Please see the Allowance for Credit Losses – Loans and Loan Commitments section of this MD&A for additional discussion).

Non-interest income is a significant source of revenue and an important part of Wesbanco’s results of operations, as it represents 22.7% of total revenue for the nine months ended September 30, 2021. Wesbanco offers its customers a wide range of retail, commercial, investment and electronic banking services, which are viewed as a vital component of Wesbanco’s ability to attract and maintain customers, as well as providing additional fee income beyond normal spread-related income to Wesbanco. For the third quarter of 2021, non-interest income decreased $1.9 million or 5.4% compared to the third quarter of 2020, primarily due to a $3.9 million decrease in mortgage banking income, a $0.8 million decrease in net securities (losses) gains and a $0.8 million decrease in debit card sponsorship income, due to the sale of the business line earlier in 2021.  The decreases were somewhat offset by a $0.9 million increase in trust fees, a $0.8 million increase in net gain (loss) on other real estate owned and other assets and a $0.7 million increase in service charges on deposits.

Trust fees increased $0.9 million or 13.4% compared to the third quarter of 2020, due to market value appreciation and organic growth. Total trust assets were $5.5 billion at September 30, 2021 as compared to $4.6 billion at September 30, 2020. As of September 30, 2021, trust assets include managed assets of $4.4 billion and non-managed (custodial) assets of $1.1 billion.  Assets managed for the WesMark Funds, a proprietary group of mutual funds that is advised by Wesbanco Trust and Investment Services, were $1.0 billion as of September 30, 2021 and $943.6 million as of September 30, 2020, and are included in managed assets.

Service charges on deposits increased $0.7 million or 13.5% to $6.1 million in the third quarter of 2021 as compared to the same period in 2020 due to increased general consumer spending over the prior period, resulting in more eligible fee-generating transactions. For the nine months ended September 30, 2021, service charges on deposits decreased $0.5 million or 2.8% compared to the nine months ended September 30, 2020 due to higher customer demand for goods and services as business conditions improved from the pandemic.

Electronic banking fees, which include debit card interchange fees, increased $0.6 million or 13.5% compared to the third quarter of 2020 as we transitioned to adjusted settlement processes of a new third-party digital banking service provider. This change occurred as part of the core conversion. For the nine months ended September 30, 2021, electronic banking fees increased $1.8 million or 13.4% compared to the nine months ended September 30, 2020.

Bank-owned life insurance increased $0.6 million or 27.2% compared to the third quarter of 2020 due to an increase in mortality-related benefits received in the current period as well as an increase in the cash surrender value, due to the purchase of an additional $40 million of bank-owned life insurance in the third quarter of 2021.

Net securities (losses) gains include both gains and losses on investment security transactions as well as market value adjustments on the deferred compensation plan.  For the three months ended September 30, 2021, net securities (losses) gains decreased $0.8 million or 101.9% compared to the same period of 2020, due to a $0.7 million decrease in market adjustments on the deferred compensation plan.  These market adjustments had an offsetting effect in employee benefits expense. For the nine months ended September 30, 2021, net securities (losses) gains decreased $2.8 million or 79.3% compared to the nine months ended September 30, 2020, due primarily to no security sales being transacted during the year 2021.  Gains on security sales totaled $2.1 million for the nine months ended September 30, 2020.

39

Mortgage banking income decreased $3.9 million or 46.2% in the third quarter of 2021 compared to the third quarter of 2020, as Wesbanco retained more 1-to-4 family mortgages on the balance sheet.  For the third quarter of 2021, mortgage production was $382.4 million, which was a decrease of 2.9% from the comparable 2020 period. For the three months ended September 30, 2021, $149.6 million in mortgages were sold into the secondary market at a net margin of 3.1% as compared to $217.6 million at a net margin of 3.9% in the comparable 2020 period. Included in mortgage banking income and the calculation of net margin noted above are losses of ($0.2) million and gains of $1.5 million from the fair value adjustments on mortgage loan commitments and related derivatives for the three months ended September 30, 2021 and 2020, respectively.  For the nine months ended September 30, 2021, mortgage banking income decreased by $0.6 million or 3.7% compared to the prior year period, due primarily to fair value adjustments of ($4.4) million and $2.2 million for the nine months ended September 30, 2021 and 2020, respectively, offsetting a $144.5 million volume increase in loans sold from the prior year period.

Debit card sponsorship income, a non-essential revenue stream for Wesbanco that was acquired in the Old Line Bancshares, Inc. (“OLBK”) acquisition and generated $0.6 million of gross revenue in the first quarter of 2021, was sold as of March 31, 2021 to another bank.  The all-cash purchase price, which will be paid out on a monthly basis over a two-year period up to a maximum of $2.8 million, is based on a 50%-50% split of the monthly gross revenue earned by the purchasing bank.  Wesbanco has recognized $0.8 million in revenue in 2021 following the sale, which is recorded in net gain (loss) on the sale of other real estate owned and other assets.

Net gain (loss) on other real estate owned and other assets increased $0.8 million in the three months ended September 30, 2021 as compared to the same period in 2020, due to a gain recognized on an investment made by Wesbanco’s Community Development Corporation in a start-up firm more than ten years ago that was recently acquired by a public company.  Net gain (loss) on other real estate owned and other assets increased by $4.9 million in the nine months ended September 30, 2021 for the same reason as discussed for the three months ended.  

Net swap fee and valuation income, which includes fair value adjustments, decreased $0.5 million or 39.7% in the third quarter of 2021 compared to the third quarter of 2020 due to a reduced volume of new swaps originated, resulting in less fee income.  For the three months ended September 30, 2021, new swaps executed totaled $9.3 million in notional principal resulting in $0.4 million of fee income, compared to new swaps executed of $25.8 million in notional principal resulting in $0.9 million of fee income for the three months ended September 30, 2020.  Fair value adjustments on existing swaps for the three months ended September 30, 2021 and 2020 were $0.4 million.  Net swap fee and valuation income increased $1.3 million or 30.3% in the first nine months of 2021 compared to the first nine months of 2020 due to higher fair value adjustments offsetting a reduced volume of new swaps in the year-to-date period.  Fair value adjustments totaled $2.1 million in the first nine months of 2021 as compared to ($2.8) million in fair value adjustments for the first nine months of 2020.

Non-interest expense in the third quarter of 2021 increased $4.8 million or 5.3% compared to the same quarter in 2020, principally from a $3.2 million increase in other operating expenses, due to $2.6 million in legal settlement costs, as well as a $1.2 million increase in salaries and wages and a $1.4 million increase in equipment and software expense. These increases were somewhat offset by a $1.4 million decrease in franchise and other miscellaneous taxes and a $0.7 million decrease in FDIC insurance expense.  In the third quarter of 2021, there were $4.5 million of restructuring expenses related to the branch optimization strategy and core operating system conversion as compared to $3.6 million of restructuring and merger-related expenses related to the OLBK acquisition and branch optimization strategy in the third quarter of 2020.  Excluding restructuring and merger-related expenses, non-interest expense increased $3.9 million or 4.5% from the third quarter of 2020 to the third quarter of 2021, and $0.8 million or 0.3% from the first nine months of 2020 to the first nine months of 2021.

Salaries and wages increased $1.2 million or 3.0% in the third quarter of 2021 from the third quarter of 2020 due primarily to increases in incentive compensation expense.  Short term incentive expense increased $1.3 million as overall higher performance in 2021 is expected as compared to 2020, along with higher incentive stock compensation expense which is up by $0.5 million from the third quarter of 2020.  Commission expense increased due to increased business transactions in commission-earning business lines, such as securities brokerage and mortgage loan originations.  These increases were mitigated by a 7.4% reduction in full time equivalent (“FTE”) employees from the third quarter of 2020 as a result of the closure of branches at various points in 2021, as the branch optimization strategy was executed, and a temporary hiring freeze earlier in 2021.  For the nine months ended September 30, 2021, salaries and wages decreased by $0.2 million or 0.2%, due primarily to the reduction in FTE employees, mostly offset by the noted increases in incentive compensation.  

Employee benefits expense increased $0.1 million or 0.5% in the third quarter of 2021 from the third quarter of 2020 as reduced pension expense and a reduction in the market adjustment on the underlying investments of the deferred compensation plan mitigated a $1.4 million increase in health insurance expense resulting from an increase in claims in the third quarter of 2021.  Employee benefits expense decreased $0.9 million or 3.0% in the first nine months of 2021 as compared to the same period in 2020 due to a decrease in pension expense and FTEs.

Equipment and software costs increased $1.4 million or 22.2% compared to the third quarter of 2020, due to the core conversion, continuous improvements in technology and communication infrastructure, an increase in asset size, increased usage of digital banking services and SBA PPP loan forgiveness fees. For the nine months ended September 30, 2021, equipment costs increased $3.7 million or 20.4% compared to the nine months ended September 30, 2020, for the same reasons as indicated for the three months ended.  

FDIC insurance decreased $0.7 million or 37.0% compared to the third quarter of 2020, due to certain improved large bank assessment rate risk factors, ultimately lowering the assessment rate.  FDIC insurance decreased $3.8 million or 58.3% in the first nine months of 2021 as compared to the first nine months of 2020, due to a $1.0 million refund received in the second quarter of 2021 from prior period call report adjustments, as well as for the reason mentioned for the three months ended.

Restructuring and merger-related expenses in the third quarter of 2021 totaled $4.5 million, an increase of $0.9 million from the third quarter of 2020. The $4.5 million of expenses in the third quarter of 2021 consisted of $3.7 million in expenses related to the core banking software conversion, including termination fees of existing contracts, and $0.8 million in branch closure and lease termination expenses associated with the closure of six branches in July as a result of the continued execution of the branch optimization strategy.  The restructuring and merger-related expenses in the third quarter of 2020 totaling $3.6 million were comprised of $3.0 million in expenses relating to the branch optimization strategy announced in the prior year’s third quarter along with $0.6 million in merger-related expenses associated with the OLBK acquisition.  For the nine months ended September 30, 2021, restructuring and merger related expenses totaled $6.5 million as compared to $9.2 million for the nine months ended in the prior year period.  The $6.5 million of expenses in the first nine months of 2021 consisted of $4.9 million in core banking software conversion expenses and $1.6 million of branch restructuring expenses, while the $9.2 million in expenses in the first nine months of 2020 consisted of $6.3 million in OLBK merger-related expenses and $2.9 million in branch restructuring expenses.

Franchise and other miscellaneous taxes decreased $1.4 million or 37.7% from the third quarter of 2020, primarily due to the elimination of Kentucky bank franchise taxes effective on January 1, 2021, as well as various state franchise tax filed return accrual adjustments and associated refunds.  Wesbanco is now subject to Kentucky state income taxes, which are reflected within the provision for income taxes on the income statement, and is part of the Company’s effective tax rate calculation.  For similar reasons, franchise and other miscellaneous taxes decreased $3.6 million or 32.2% in the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020.

INCOME TAXES

The provision for income taxes was $10.7 million for the three months ended September 30, 2021, which is a $3.0 million increase compared to $7.7 million for the three months ended September 30, 2020. The increase in the provision for income taxes is due to an increase in the effective tax rate to 19.3% in the third quarter of 2021 compared to 15.7% in the third quarter of 2020.  This increase resulted from higher pre-tax income primarily due to the negative provision for credit losses recorded in the third quarter of 2021, as compared to an increased provision for credit losses in the third quarter of 2020 due to the pandemic.  In addition, as mentioned above, Kentucky state income taxes are now reflected within the provision for income taxes and the effective tax rate calculation for 2021.  For the nine months ended September 30, 2021, the provision for income taxes was $47.4 million as compared to $11.3 million for the nine months ended September 30, 2020, reflecting the same reasons above as for the three months ended.

FINANCIAL CONDITION

Total assets and deposits increased 2.8% and 8.0%, respectively, while shareholders’ equity decreased 1.2%, compared to December 31, 2020. Total securities increased $1.2 billion or 45.3% from December 31, 2020 to September 30, 2021, primarily driven by the purchase of mortgage-backed securities and municipal obligations with additional liquidity provided by CARES Act individual and family payments, as well as deposits from small businesses obtaining loans from the PPP program. The securities’ increase was partially offset by a $37.1 million decrease in unrealized gains in the available-for-sale portfolio. Total portfolio loans, excluding PPP loans, decreased $421.9 million or 4.2% as commercial, residential real estate, home equity and consumer loan pay downs outpaced new originations. Forgiveness related to the 2020 and 2021 PPP loan programs totaled $939.7 million through the first nine months of 2021. Deposits increased $993.9 million from year-end resulting from increases of 13.1%, 12.4%, and 4.7% in demand deposits, savings deposits, and money market deposits, respectively, which were partially offset by a 16.3% decrease in certificates of deposit. The growth in transaction-based accounts is primarily attributable to CARES Act stimulus funds received, increased personal savings and reduced customer spending, focused retail and business strategies to obtain more account relationships and customers’ preferences for shorter-term maturities. The transaction accounts also increased from business customers obtaining loans from the PPP loan program and depositing proceeds in their checking accounts.  Deposits were also somewhat impacted by bonus and royalty payments for Marcellus and Utica shale gas payments from energy companies in Wesbanco’s southwestern Pennsylvania, eastern Ohio, and northern West Virginia markets. The decrease in certificates of deposit is a result of lower overall rates and management periodically offering lower than median competitive rates for maturing certificates of deposit and customer preferences for other deposit types, which was partially offset by a $3.3 million increase in CDARS® balances.  Also, certain IRA accounts were reclassified to savings account types upon the core conversion in August. Total borrowings decreased 46.2% or $454.0 million during the first nine months of 2021 as additional liquidity permitted the pay down of maturing FHLB advances by $340.1 million, coupled with an $89.4 million decrease in other short-term borrowings, and a $24.6 million decrease in subordinated debentures primarily from a $25.0 million early redemption in the third quarter.  Total shareholders’ equity decreased approximately $32.8 million or 1.2%, compared to December 31, 2020, primarily due to a $26.9 million decrease in other comprehensive income and the repurchase of common shares totaling $128.0 million, which were partially offset by net income exceeding dividends for the period by $115.1 million.

⁽¹⁾ At September 30, 2021 and December 31, 2020, 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.

⁽²⁾ Weighted average yields have been calculated on a taxable-equivalent basis using the federal statutory tax rate of 21%.

Total investment securities, which are a source of liquidity for Wesbanco as well as a contributor to interest income, increased $1.2 billion or 45.2% from December 31, 2020 to September 30, 2021, and represented 23.4% of total assets at period-end as compared to 16.6% at December 31, 2020.  Through the first nine months of 2021, the available-for-sale portfolio increased $1.0 billion or 51.0%, primarily due to excess liquidity from stimulus deposits and increased calls of agency and municipal securities, funding $1.7 billion in purchases of residential mortgage-backed securities and collateralized mortgage obligations.  Residential mortgage-backed securities and collateralized mortgage obligations totaled 59.6% of the total investment portfolio at September 30, 2021. The held-to-maturity portfolio increased $222.7 million or 30.5% due to $307.2 million in purchases of municipal bonds.  The weighted average yield of the portfolio decreased by 53 basis points from 2.43% at December 31, 2020 to 1.90% at September 30, 2021, due to prepayments and calls of legacy higher rate agency and municipal securities and the previously mentioned purchases at lower current market rates.  Higher premium amortization was also a factor in the yield reduction.

Net unrealized gains on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of September 30, 2021 and December 31, 2020 were $18.5 million and $46.9 million, respectively.  The net unrealized pre-tax gains represent temporary fluctuations resulting from changes in market rates in relation to fixed yields in the available-for-sale portfolio, and on an after tax-basis are accounted for as an adjustment to other comprehensive income in shareholders’ equity.   Net unrealized pre-tax gains in the held-to-maturity portfolio, which are not accounted for in other comprehensive income, were $24.6 million at September 30, 2021, compared to $37.0 million at December 31, 2020.  With approximately 24% of the investment portfolio in the held-to-maturity category, the recent volatility in interest rates does not have as much impact on other comprehensive income as if the entire portfolio were included in the available-for-sale category. The decrease in unrealized gains from year-end is due to an increase in market rates over the first nine months of the year coupled with prepayments and calls of higher-rate securities, and purchases of securities at lower, current market rates.

43

Equity securities, of which a portion consist of investments in various mutual funds held in grantor trusts formed in connection with a key officer and director deferred compensation plan, are recorded at fair value. Gains and losses due to fair value fluctuations on equity securities are included in net securities gains or losses.  For those equity securities relating to the key officer and director deferred compensation plan, the corresponding change in the obligation to the employee is recognized in employee benefits expense.

Wesbanco’s municipal portfolio represented 24.3% of the overall securities portfolio as of September 30, 2021 compared to 26.3% as of December 31, 2020, and it carries different risks that are not as prevalent in other security types contained in the portfolio.

Wesbanco uses prices from independent pricing services and, to a lesser extent, indicative (non-binding) quotes from independent brokers, to measure the fair value of its securities. Wesbanco validates prices received from pricing services or brokers using a variety of methods, including, but not limited to, comparison to secondary pricing services, corroboration of pricing by reference to other independent market data such as secondary broker quotes and relevant benchmark indices, review of pricing by personnel familiar with market liquidity and other market-related conditions, review of pricing service methodologies, review of independent auditor reports received from the pricing service regarding its internal controls, and through review of inputs and assumptions used in pricing certain securities thinly traded or with limited observable data points.  The procedures in place provide management with a sufficient understanding of the valuation models, assumptions, inputs and pricing to reasonably measure the fair

44

value of Wesbanco’s securities.  For additional disclosure relating to fair value measurements, refer to Note 7, “Fair Value Measurement” in the Consolidated Financial Statements.

LOANS AND CREDIT RISK

Loans represent Wesbanco’s single largest balance sheet asset classification and the largest source of interest income.  Business purpose loans consist of CRE loans and other C&I loans that are not secured by real estate.  CRE loans are further segmented into land and construction loans, and loans for improved property.  Consumer purpose loans consist of residential real estate loans, home equity lines of credit and other consumer loans.  Loans held for sale generally consist of residential real estate loans originated for sale in the secondary market, but at times may also include other types of loans.  The outstanding balance of each major category of the loan portfolio is summarized in Table 10.  

The risk that borrowers will be unable or unwilling to repay their obligations and default on loans is inherent in all lending activities.  Credit risk arises from many sources including general economic conditions, external events that impact businesses or industries, isolated events that impact a major employer, individual loss of employment or other personal hardships as well as changes in interest rates or the value of collateral.  Credit risk is also impacted by a concentration of exposure within a geographic market or to one or more borrowers, industries or collateral types.  The primary goal in managing credit risk is to minimize the impact of default by an individual borrower or group of borrowers.  Credit risk is managed through the initial underwriting process as well as through ongoing monitoring and administration of the portfolio that varies by the type of loan.  The Bank’s credit policies establish standard underwriting guidelines for each type of loan and require an appropriate evaluation of the credit characteristics of each borrower.  This evaluation includes the borrower’s primary source of repayment capacity; the adequacy of collateral, if any, to secure the loan; the potential value of personal guarantees as secondary sources of repayment; and other factors unique to each loan that may increase or mitigate its risk.  Credit bureau scores are also considered when evaluating consumer purpose loans as well as guarantors of business purpose loans.  However, the Bank does not periodically update credit bureau scores subsequent to when loans are made to determine changes in credit history.  

Credit risk is mitigated for all types of loans by continuously monitoring delinquency levels and pursuing collection efforts at the earliest stage of delinquency.  The Bank also monitors general economic conditions, including employment, housing activity and real estate values in its market.  The Bank also periodically evaluates and changes its underwriting standards when warranted based on market conditions, the historical performance of a category of the portfolio, or other external factors.  Credit risk is also regularly evaluated for the impact of adverse economic and other events, such as the current COVID-19 pandemic crisis, that increase the risk of default and the potential loss in the event of default, to understand the impact on the Bank’s earnings and capital.

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 and guarantees.

⁽¹⁾ Loans are presented gross of the allowance for loan credit losses – loans and net of unearned income, credit valuation adjustments, and unamortized net deferred loan fee income and loan origination costs.

Total portfolio loans decreased $876.1 million or 8.1% from December 31, 2020, while they decreased $1.1 billion or 9.8% over the last twelve months.  Most of the loan decrease was due to the forgiveness of $939.7 million of PPP loans during the last twelve months, of which $272.1 million remain in the portfolio as of September 30, 2021.  Excluding PPP loans, total portfolio loans decreased over the last twelve months by 4.9% reflecting the higher than anticipated commercial real estate payoffs, continued low commercial line of credit utilization, and the impact of selling a higher percentage of 1-to-4 family residential mortgage originations in the secondary market. Consumer loan demand also decreased as a result of the pandemic reducing consumer spending.  Slightly offsetting the total decrease was 19.4% of growth in the land and construction portfolio.  This increase is due to $187.1 million of loan reclassifications out of commercial real estate in the third quarter of 2021.  Commercial and industrial loans decreased 13.2%, due to lower overall demand and partially from certain reclassifications into commercial real estate.  Residential real estate loans decreased 7.9% over the last twelve months, due to a greater portion of new originations sold into the secondary market and a greater portion of existing loans refinanced with other banks, while home equity loans experienced lower demand and were also refinanced into first mortgages due to customer preferences for fixed rate loans.  Consumer loans declined due to pricing adjustments for indirect lending as well as refinancing or repayment of existing loans.  

45

Total loan commitments of $3.8 billion, including loans approved but not closed, increased $553.2 million or 17.1% from December 31, 2020 due primarily to increases in availabilities under lines of credit, deposit overdrafts and contingent obligations.  The line utilization percentage for the commercial portfolio was 37.0% at September 30, 2021 compared to 33.9% as of December 31, 2020.

The commercial portfolio is monitored for potential concentrations of credit risk by market, type of lending, CRE property type, C&I and owner-occupied CRE by industry, investment CRE dependence on common tenants and industries or property types that are similarly impacted by external factors.

Loans held for sale at both September 30, 2021 and December 31, 2020 are originated residential mortgages that are committed to be sold into the secondary market.  Loans held for sale decreased by $136.1 million or 80.8% from December 31, 2020 due to additional staffing in the secondary mortgage operations area and a specific effort to accelerate the speed at which the loans are delivered to the investor, as well as more originations held in the loan portfolio in the third quarter.      

Wesbanco has participated in the PPP loan program as originally established by the CARES Act. As of September 30, 2021, the Company has funded nearly 11,300 loans totaling $1.2 billion to qualifying small businesses, non-profits and organizations throughout our six-state footprint. The loans carry an interest rate of 1%, are generally for a two-year or five-year maturity, and were originated with a percentage fee paid by the SBA directly to the Bank depending on the size of the loan originated. At September 30, 2021, remaining unaccreted fees, net of deferred origination costs, were $10.4 million.  This total is comprised of $10.1 million remaining on the 2021 originated PPP loans and $0.3 million remaining on the 2020 originated PPP loans. The loans are subject to forgiveness by the SBA under certain defined circumstances, and it is anticipated a high percentage of such loans will meet such requirements (as revised) over the next few quarters, with $825.4 million of 2020 originated PPP loans, or approximately 97% of 2020 PPP loan originations and $114.3 million, or approximately 31% of 2021 PPP loan originations, having been forgiven as of September 30, 2021.

Wesbanco met the needs of the communities it serves by providing appropriate relief tailored to the individual needs of the customer, ranging from three months of interest-only for those minimally impacted, up to and including full principal and interest deferral for six months for those significantly impacted, while also providing additional tailored relief to the hospitality industry where appropriate.  The relief was provided in as many as three phases depending on the circumstances.

Under the CARES Act, Wesbanco modified approximately 3,550 loans totaling $2.2 billion in 2020, of which a total of $132.8 million of commercial loans, representing 1.3% of total portfolio loans remain in deferral as of September 30, 2021.  An additional $97.9 million of commercial loans had various payment terms modified in exchange for enhancements beneficial to the Bank which were permanent improvements to the credit facility.  Changes include an increase in floor rates, increase in guarantors and duration of guarantees and a change in covenants.  None of the aforementioned loans were considered delinquent or on non-accrual status as of September 30, 2021.  

NON-PERFORMING ASSETS AND LOANS PAST DUE 90 DAYS OR MORE

Non-performing assets consist of non-accrual loans and TDRs, other real estate acquired through or in lieu of foreclosure, bank premises held for sale, and repossessed automobiles acquired to satisfy defaulted consumer loans.

(1) TDRs on non-accrual of $1.6 million as of September 30, 2021 and $1.8 million as of December 31, 2020, respectively, are included in total non-accrual loans.

Non-performing loans, which consist of non-accrual loans and TDRs, decreased $0.8 million or 2.1%, from December 31, 2020.  Non-accrual balances have decreased $0.6 million and accruing TDR balance decreased $0.2 million from December 31, 2020 to September 30, 2021.  (Please see the Notes to the Consolidated Financial Statements for additional discussion.)  

Section 4013 of the CARES Act allows financial institutions the option to temporarily suspend certain requirements under U.S. 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 as of December 31, 2019, as well as other requirements. Based on this guidance, Wesbanco did not classify the COVID-19 loan modifications as TDRs, nor are the customers considered past due with regards 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. Through September 30, 2021, Wesbanco has offered various deferred payment schedules to commercial and retail customers impacted by the COVID-19 pandemic, depending on the type of loan and the industry-type for commercial loans.  

Other real estate owned and repossessed assets decreased to $0.3 million from December 31, 2020. At September 30, 2021 and December 31, 2020, formal foreclosure proceedings were in process on residential real estate loans totaling $1.9 million and $1.8 million at each period, respectively.  As a result of provisions of the CARES Act, certain residential real estate loans are temporarily suspended from entering foreclosure proceedings.  The balance of these loans totaled $3.6 million and $2.3 million at September 30, 2021 and December 31, 2020, respectively.

The following table presents past due and accruing loans excluding non-accrual and TDRs:

Loans past due 30 days or more and accruing interest, excluding non-accruals and TDRs, increased $3.5 million or 8.6% from December 31, 2020.  These loans continue to accrue interest because they are both well-secured and in the process of collection.  Loans 90 days or more past due increased $2.4 million and represented 0.11% and 0.08% of total portfolio loans at September 30, 2021 and December 31, 2020, respectively. Loans 90 days past due increased in the commercial and industrial category due to one $3.2 million loan.  The 30 – 89 days past due category represented 0.33% of total loans at September 30, 2021 and 0.29% at December 31, 2020.  Loans currently modified as permitted by the regulatory authorities and the CARES Act are not included in Tables 13 or 14, as they are not considered past due.

ALLOWANCE FOR CREDIT LOSSES - LOANS AND LOAN COMMITMENTS

As of September 30, 2021, the total allowance for credit losses – loans and commitments was $143.9 million, of which $136.6 million related to loans and $7.3 million related to loan commitments. The allowance for credit losses – loans was 1.38% of total portfolio loans as of September 30, 2021, compared to 1.72% as of December 31, 2020. Excluding PPP loans of $272.1 million, the allowance for credit losses – loans was 1.42% of total portfolio loans as of September 30, 2021, as compared to 1.85% of total portfolio loans at December 31, 2020. As per regulatory guidance, there is no calculated allowance on PPP loans due to their government guarantees by the SBA.

The allowance for credit losses - loans individually-evaluated increased $11.0 million from December 31, 2020 to September 30, 2021.  The population of individually-evaluated loans consisted of eight hotel loans, with a total loan balance of $37.1 million.  These loans were moved to individually-evaluated in the third quarter of 2021.  The allowance for loans collectively-evaluated decreased from December 31, 2020 to September 30, 2021 by $60.2 million.  

The allowance for credit losses - loan commitments was $7.3 million at September 30, 2021 as compared to $9.5 million as of December 31, 2020, and is included in other liabilities on the Consolidated Balance Sheets.

The allowance for credit losses by loan category, presented in Note 4, “Loans and the Allowance for Credit Losses” of the Consolidated Financial Statements, summarizes the impact of changes in various factors that affect the allowance for loan losses in each segment of the portfolio. The allowance for credit losses under CECL is calculated utilizing the PD/LGD, which is then discounted to net present value. PD is the probability the asset will default within a given time frame and LGD is the percentage of the asset not expected to be collected due to default. The primary macroeconomic drivers of the quantitative model include forecasts of national unemployment and interest rates, as well as modeling adjustments for changes in prepayment speeds, loan risk grades, portfolio mix, concentrations and loan growth. For the calculation as of September 30, 2021, the forecast was based upon a blend of two nationally-recognized published economic forecasts through September 30, 2021, and was primarily driven by national unemployment and interest rate spread forecasts. At quarter-end, national unemployment was projected to peak at 4.7%, and subsequently decrease to an average of 4.0% over the remainder of the forecast period. The resurgence in leisure travel continued through September 30, 2021, which led to improvements in debt service coverage and revenue per available room (“RevPAR”) across the hotel portfolio. The improvement in the macroeconomic factors and COVID qualitative factors, including those specifically for the hospitality portfolio, caused the allowance to decrease from December 31, 2020 to September 30, 2021, by $51.4 million.

If forecasted projections of national unemployment remain consistent with the forecast utilized by Wesbanco as of September 30, 2021 throughout the rest of the year, this may result in additional, but less significant, future quarterly decreases in the allowance for credit losses, depending upon other model variables such as qualitative factors specifically for hotels and the COVID-19 pandemic.

Criticized and classified loans were 4.2% of total portfolio loans, decreasing from 4.6% at December 31, 2020. Criticized and classified loans decreased $77.6 million from December 31, 2020 to $417.3 million at September 30, 2021, primarily due to upgrades on certain hospitality loans.  See Footnote 4, “Loans and the Allowance for Credit Losses” for more information.  

Table 13 summarizes the allocation of the allowance for credit losses to each category of the loan portfolio.

Total allowance for credit losses - loans and loan commitments	$	143,895		100.0	$	195,341		100.0

Although the allowance for credit losses is allocated as described in Table 13, the total allowance is available to absorb actual losses in any category of the loan portfolio.  However, differences between management’s estimation of probable losses and actual net charge-offs in subsequent periods for any category may necessitate future adjustments to the allowance for credit losses applicable to the category.  Management believes the allowance for credit losses is appropriate to absorb expected losses at September 30, 2021.

DEPOSITS

48

Deposits, which represent Wesbanco’s primary source of funds, are offered in various account forms at various rates through Wesbanco’s 206 financial centers.  The FDIC insures deposits up to $250,000 per account.

Total deposits increased by $993.9 million or 8.0% during the first nine months of 2021.  Interest bearing demand deposits, savings deposits, non-interest bearing demand deposits, and money market deposits increased 15.6%, 12.4%, 11.3%, and 4.7%, respectively. The growth in transaction-based accounts is primarily attributable to individual and family stimulus payments, as well as deposits from small businesses obtaining loans from the PPP program, focused retail and business strategies to obtain more account relationships and customers’ overall preferences for shorter-term maturities. Deposit balances were also impacted by bonus and royalty payments for Marcellus and Utica shale gas payments from energy companies in Wesbanco’s southwestern Pennsylvania, eastern Ohio and northern West Virginia markets. Money market deposits were influenced through Wesbanco’s participation in the Insured Cash Sweep (ICS®) money market deposit program. ICS® reciprocal balances totaled $647.3 million at September 30, 2021 compared to $513.9 million at December 31, 2020.

Certificates of deposit decreased $264.3 million from December 31, 2020 to September 30, 2021 due primarily to the effects of an overall corporate strategy designed to increase and remix retail deposit relationships and reduce single-service customers with a focus on overall products that can be offered at a lower cost to Wesbanco.  The decline was also impacted by customer run-off of higher cost certificates of deposit from the OLBK acquisition and customer preferences for transaction account types.  Wesbanco does not generally solicit brokered or other deposits out-of-market or over the internet, but does participate in the Certificate of Deposit Account Registry Services (CDARS®) program. CDARS® balances totaled $45.9 million in outstanding balances at September 30, 2021, compared to $42.6 million in total outstanding balances at December 31, 2020. Certificates of deposit greater than $250,000 were approximately $329.6 million at September 30, 2021 compared to $381.7 million at December 31, 2020. Certificates of deposit of $100,000 or more were approximately $701.9 million at September 30, 2021 compared to $843.2 million at December 31, 2020.  Certificates of deposit totaling approximately $893.7 million at September 30, 2021 with a cost of 0.50% are scheduled to mature within the next 12 months.  Wesbanco intends to continue to focus on its core deposit strategies and improving its overall mix of transaction accounts to total deposits.  From time to time, the Bank may offer special promotions or match competitor rates on certain certificates of deposit maturities and savings products based on competition, sales strategies, liquidity needs and wholesale borrowing costs.

BORROWINGS

TABLE 15. BORROWINGS

(unaudited, dollars in thousands)	September 30, 2021		December 31, 2020		$ Change			% Change
Federal Home Loan Bank Borrowings	$	208,940	$	549,003	$	(340,063	)		(61.9	)
Other short-term borrowings		152,546		241,950		(89,404	)		(37.0	)
Subordinated debt and junior subordinated debt		167,711		192,291		(24,580	)		(12.8	)
Total	$	529,197	$	983,244	$	(454,047	)		(46.2	)

While borrowings are a significant source of funding for Wesbanco, they are less significant as compared to total deposits. During the first nine months of 2021, $340.1 million in available liquidity was used for FHLB borrowings maturities and other principal pay-downs with an average cost of 2.40%. There were no new FHLB advances during the period.

Other short-term borrowings, which may consist of federal funds purchased, callable repurchase agreements, overnight sweep checking accounts, and borrowings on a revolving line of credit, were $152.5 million at September 30, 2021 compared to $242.0 million at December 31, 2020.  The decrease in these borrowings is primarily due to an $89.4 million decrease in callable repurchase agreements and overnight sweep checking accounts. The decrease in callable repurchase agreements is due to moving certain customer relationships to interest-bearing demand deposits. There were no outstanding federal funds purchased at either September 30, 2021 or December 31, 2020.

Subordinated debt and junior subordinated debt balances decreased by $24.6 million or 12.8% from the third quarter of 2020 to the third quarter of 2021.  This decrease is due specifically to the early redemption of the Your Community Bank (“YCB”) subordinated debt in the middle of September.  In addition, it was previously announced that Wesbanco will be redeeming the $35.0 million OLBK subordinated debt in the fourth quarter of 2021.

Wesbanco renewed a revolving line of credit in August 2021, which is a senior obligation of the parent company, with another financial institution.  This line of credit, which accrues interest at an adjusted LIBOR rate, provides for aggregate unsecured borrowings of up to $30.0 million. There were no outstanding balances at either September 30, 2021 or December 31, 2020.  

49

OFF-BALANCE SHEET ARRANGEMENTS

Wesbanco enters into financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, letters of credit, loans approved but not closed, overdraft limits and contingent obligations to purchase loans funded by other entities. Since many of these commitments expire unused or partially used, these commitments may not reflect future cash requirements.  Please refer to Note 10, “Commitments and Contingent Liabilities,” of the Consolidated Financial Statements and the “Loans and Credit Risk” section of this MD&A for additional information.

The allowance for credit losses includes an allowance for unfunded loan commitments.  The allowance for credit losses represents the lifetime expected losses for all loans and unfunded loan commitments at the initial recognition date. 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, which also includes any necessary adjustments to the reserve for unfunded loan commitments, and such reserve is accounted for in other liabilities. 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. 

CAPITAL RESOURCES

Shareholders' equity decreased $32.8 million or 1.2% from $2.8 billion at December 31, 2020.  The decrease resulted from the repurchase of common shares totaling $128.0 million, the declaration of common and preferred shareholder dividends totaling $65.1 million and $7.6 million, respectively, and a $26.9 million other comprehensive loss for the nine months ended September 30, 2021 exceeding net income during the current nine-month period of $188.1 million. Wesbanco also increased its quarterly dividend rate $0.01 per quarter to $0.33 per share in February, representing a 3.1% increase over the prior quarterly rate and a cumulative 136% increase since 2010.

Wesbanco purchased 3,643,656 shares of its common stock on the open market at a total cost of $128.0 million, or $35.13 per share during the nine-month period ended September 30, 2021 under current share repurchase authorizations. The Board of Directors approved an additional stock repurchase plan for the purchase of up to 3.2 million shares on August 26, 2021, which was in addition to prior plans that were utilized during the quarter. At September 30, 2021, the remaining shares authorized to be purchased under the last approved repurchase plan totaled 2,960,801 shares.  

In February 2021, Wesbanco granted 12,000 Total Shareholder Return Plan (“TSR”) shares for the performance period beginning January 1, 2021 and ending December 31, 2023 to certain executives. 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 50^th 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 75^th percentile of the TSR of the peer group.  Upon achieving the market-based metric, shares determined to be earned by the participant become time-based and vest in three equal annual installments.

On May 19, 2021, Wesbanco granted 147,200 stock options to selected officers at an exercise price of $38.78. These options are service-based and vest 50% at May 19, 2022 and 50% at December 31, 2022. On the same date, Wesbanco issued 122,656 shares of time-based restricted stock to selected officers and directors and 17,571 shares of performance-based restricted stock to selected officers. The time-based restricted shares are service-based and cliff-vest 36 months from the date of grant. The performance-based restricted shares have a three-year performance period beginning on January 1, 2022, based on Wesbanco’s return on average assets and return on average tangible common equity measured for each year, compared to a national set of peer financial institutions.

On June 24, 2021, Wesbanco issued an additional 6,165 shares of time-based restricted stock to directors. These time-based restricted shares are service-based and cliff-vest 36 months from the date of grant.

Regulatory guidelines require bank holding companies and commercial banks to maintain certain minimum capital ratios and define companies as “well capitalized” that sufficiently exceed the minimum ratios.  At September 30, 2021, regulatory capital levels for both the Bank and Wesbanco were substantially greater than the minimum amounts needed to be considered “well capitalized” under the regulations.  There are various legal limitations under federal and state laws that limit the payment of dividends from the Bank to Wesbanco. As of September 30, 2021, under FDIC regulations, Wesbanco could receive, without prior regulatory approval, a dividend of approximately $253.7 million from the Bank.  Wesbanco expects to continue to improve its consolidated and Bank capital ratios as necessary over time, to fund organic growth and acquisitions, primarily from retaining a majority of its earnings.

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 September 30, 2021 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 25 to 40 basis points for three of the four regulatory ratios, while total risk-based capital would have been slightly higher without the transition.

LIQUIDITY RISK

Liquidity is defined as a financial institution’s capacity to meet its cash and collateral obligations at a reasonable cost.  Liquidity risk is the risk that an institution’s financial condition or overall safety and soundness is adversely affected by an inability, or perceived inability, to meet its obligations. An institution’s obligations, and the funding sources to meet them, depend significantly on its business mix, balance sheet structure, and the cash flows of its on- and off-balance sheet obligations. Institutions confront various internal and external situations that can give rise to increased liquidity risk including funding mismatches, market constraints on funding sources, contingent liquidity events, changes in economic conditions, and exposure to credit, market, operation, legal and reputation risk.  Wesbanco actively manages liquidity risk through its ability to provide adequate funds to meet changes in loan demand, unexpected outflows in deposits and other borrowings as well as to take advantage of market opportunities and meet operating cash needs. This is accomplished by maintaining liquid assets in the form of securities, sufficient borrowing capacity and a stable core deposit base.  Liquidity is centrally monitored by Wesbanco’s Asset/Liability Committee (“ALCO”).

Wesbanco determines the degree of required liquidity by the relationship of total holdings of liquid assets to the possible need for funds to meet unexpected deposit losses and/or loan demands.  The ability to quickly convert assets to cash at a minimal loss is a primary function of Wesbanco’s investment portfolio management. Wesbanco believes its cash flow from the loan portfolio, the investment portfolio, and other sources, adequately meet its liquidity requirements. Wesbanco’s net loans to assets ratio was 57.9% at September 30, 2021 and deposit balances funded 79.5% of assets.  

The following table lists the sources of liquidity from assets at September 30, 2021 expected within the next year:

(unaudited, in thousands)
Cash and cash equivalents	$	1,121,116
Securities with a maturity date within the next year and callable securities		239,028
Projected payments and prepayments on mortgage-backed securities and collateralized mortgage obligations (1)		693,052
Loans held for sale		32,308
Accruing loans scheduled to mature		1,160,888
Normal loan repayments		2,218,268
Total sources of liquidity expected within the next year	$	5,464,660

⁽¹⁾ Projected prepayments are based on current prepayment speeds.

Deposit flows are another principal factor affecting overall Wesbanco liquidity. Deposits totaled $13.4 billion at September 30, 2021. Deposit flows are impacted by current interest rates, products and rates offered by Wesbanco versus various forms of competition, as well as customer behavior. Certificates of deposit scheduled to mature within one year totaled $893.7 million at September 30, 2021, which includes jumbo regular certificates of deposit totaling $448.1 million with a weighted-average cost of 0.59%, and jumbo CDARS^® deposits of $8.8 million with a weighted-average cost of 1.79%.  

Wesbanco maintains a line of credit with the FHLB as an additional funding source. Available credit with the FHLB approximated $4.0 billion and $3.6 billion at September 30, 2021 and December 31, 2020, respectively.  The FHLB requires securities to be specifically pledged to the FHLB and maintained in a FHLB-approved custodial arrangement if the member wishes to include such securities in the maximum borrowing capacity calculation.  Wesbanco has elected not to specifically pledge to the FHLB otherwise unpledged securities. At September 30, 2021, the Bank had unpledged available-for-sale securities with an amortized cost of $1.0 billion, or 35.6% of the total available-for-sale portfolio. A portion of these securities could be sold for additional liquidity, or such securities could be pledged to secure additional FHLB borrowings.  A significant portion of the portfolio is pledged to public deposit customers, as public deposit balances have increased significantly through the several acquisitions made since 2015, to a total of $1.6 billion at September 30, 2021.  Wesbanco’s held-to-maturity portfolio currently contains $793.2 million of unpledged securities. Most of these securities are tax-exempt municipal securities, which can only be pledged in limited circumstances. Generally, these securities cannot be sold without tainting the remainder of the held-to-maturity portfolio.  If tainting occurs, all remaining securities with the held-to-maturity designation would be required to be reclassified as available-for-sale, and the held-to-maturity designation would not be available to Wesbanco for a period of time.

51

Wesbanco participates in the Federal Reserve Bank’s Borrower-in-Custody Program (“BIC”) whereby Wesbanco pledges certain consumer loans as collateral for borrowings. Wesbanco did not have any BIC borrowings outstanding at September 30, 2021.  Alternative funding sources may include the utilization of existing overnight lines of credit with third party banks totaling $275.0 million, none of which was outstanding at September 30, 2021, along with seeking other lines of credit, borrowings under repurchase agreement lines, increasing deposit rates to attract additional funds, accessing brokered deposits, or selling securities available-for-sale or certain types of loans.

Other short-term borrowings of $152.5 million at September 30, 2021 consisted of callable repurchase agreements and overnight sweep checking accounts for large commercial customers. Other short-term borrowings may also include federal funds purchased.  There has been a decrease in average balances of overnight sweep checking accounts during the first nine months of 2021, primarily from the movement of overnight sweep checking accounts to transaction account deposits to reduce pledging.  The overnight sweep checking accounts require U.S. Government securities to be pledged equal to or greater than the average deposit balance in the related customer accounts.  

The principal sources of parent company liquidity are dividends from the Bank, $148.2 million in cash on hand, and a $30.0 million revolving line of credit with another bank, which did not have an outstanding balance at September 30, 2021.  Wesbanco is in compliance with all applicable loan covenants.  There are various legal limitations under federal and state laws that limit the payment of dividends from the Bank to the parent company. As of September 30, 2021, under FDIC and State of West Virginia regulations, Wesbanco could receive, without prior regulatory approval, dividends of approximately $253.7 million from the Bank.  Management believes these are appropriate levels of cash for the parent company given the current environment.  Management continuously monitors the adequacy of parent company cash levels and sources of liquidity through the use of metrics that relate current cash levels to historical and forecasted cash inflows and outflows.

Wesbanco had outstanding commitments to extend credit in the ordinary course of business approximating $3.7 billion and $3.0 billion at September 30, 2021 and December 31, 2020, respectively. On a historical basis, only a portion of these commitments will result in an outflow of funds. Please refer to Note 10, “Commitments and Contingent Liabilities” of the Consolidated Financial Statements and the “Loans and Credit Risk” section of this MD&A for additional information.

Federal financial regulatory agencies have previously issued guidance to provide for sound practices for managing funding and liquidity risk and strengthening liquidity risk management practices. Wesbanco maintains a comprehensive management process for identifying, measuring, monitoring, and controlling liquidity risk, which is fully integrated into its risk management process.  Management believes Wesbanco has sufficient current liquidity to meet current obligations to borrowers, depositors and others and that Wesbanco’s current liquidity risk management policies and procedures, as periodically reviewed and adjusted, adequately address this guidance.

LIBOR TRANSITION

The London Interbank Offered Rate (“LIBOR”) is a widely used short-term reference interest rate benchmark for variable rate loans and securities, borrowings, and interest rate hedge/swap transactions.  In July of 2017, the U.K. Financial Conduct Authority (“FCA”) announced the discontinuation of LIBOR after certain banks provided purported interest rate figures which did not truly reflect the rate at which they could borrow.  In addition to FCA, as early as 2014, financial institution regulators and the Federal Financial Institutions Examination Council (“FFIEC”) began to work to develop a uniform approach to the phase-out of LIBOR because the continued reliance on LIBOR could present systematic risk to financial institutions. The Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York convened the Alternative Reference Rates Committee (“AARC”) to identify alternative reference rates to LIBOR.  The AARC released consultations on contractual fallback language to prepare for the transition away for LIBOR and on June 22, 2017, identified the Secured Overnight Financing Rate (“SOFR”) as the recommended alternative to LIBOR.

On July 1, 2020, the FFIEC issued a Joint Statement on Managing the LIBOR Transition to further explain that new financial contracts should either utilize a reference rate other than LIBOR or have robust fallback language that defines an alternative reference rate after LIBOR’s discontinuation.  The FFIEC statement encouraged supervised financial institutions to continue their efforts to prepare for the change and address the risks associated with the LIBOR transition.

On November 6, 2020, the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency, and the Federal Deposit Insurance Corporation (collectively, the “Agencies”) issued a statement providing that a financial institution may use any reference rate for its loans that the financial institution determines to be appropriate for its funding model and customer needs.  

Thereafter, on November 30, 2020, the Agencies issued an additional joint statement encouraging financial institutions to continue to transition away from LIBOR as soon as practicable, but no later than December 31, 2021.  Given the risks associated with the use of LIBOR, the Agencies stated that entering into new contracts that use LIBOR as a reference rate after December 31, 2021, would create safety and soundness risks.

On March 5, 2021, the U.K. FCA and Intercontinental Exchange (“ICE”) Benchmark Administration announced that the publication of the overnight, as well as, the one, three, six, and twelve month LIBOR rates will continue to be published through June 30, 2023, which will provide additional time to wind down or renegotiate existing contracts that reference LIBOR.  

On October 20, 2021, the Agencies with the Consumer Financial Protection Bureau, National Credit Union Administration, and State Bank and Credit Union Regulators, issued an additional Joint Statement on Managing the LIBOR Transition to once again emphasize the expectation that supervised institutions with LIBOR exposure continue to progress toward an orderly transition away from LIBOR.  The statement confirmed that entering into new contracts, including derivatives that use LIBOR as a reference rate after December 31, 2021, would create safety and soundness risks, including litigation, operational, and consumer protection risks.    

52

As early as 2018, in anticipation of the potential discontinuance of LIBOR, Wesbanco established a LIBOR transition committee to effectively manage the Company’s transition away from LIBOR in two phases. The first phase included adding additional fallback language to loan documents to allow Wesbanco to replace LIBOR with an equivalent rate index plus the margin to ensure the resulting interest rate is the same as it previously was using LIBOR.  Also, as part of the first phase,  Wesbanco began quoting to the Treasury Rate published by the Federal Reserve Board instead of the ICE LIBOR Swap Index (which is tied to LIBOR) when repricing certain term loans and originating new loans. The second phase consists of working to continue to transition existing adjustable-rate loans that fluctuate monthly or periodically that are tied to LIBOR or the ICE LIBOR Swap Index. Wesbanco is tracking the dollar amount and number of loans tied to LIBOR or the ICE LIBOR Swap Index, monitoring current industry trends, and working with legal counsel to ensure the smooth transition away from LIBOR.  As of September 30, 2021, Wesbanco had a total of $1.9 billion in loans tied to either LIBOR or the ICE LIBOR Swap index, of which $1.5 billion have a maturity date after June 30, 2023. As referenced above, the U.K. FCA and ICE Benchmark Administration has extended the date of publication of certain tenors of LIBOR through June 30, 2023, giving existing LIBOR based contracts time to mature.  However, in compliance with and based upon the Agencies Joint Statements referenced above, Wesbanco will not be offering LIBOR for new contracts after December 31, 2021. Accordingly, Wesbanco has initially chosen the One Month Term Secured Overnight Financing Rate (“1M Term SOFR”), which is published by the Chicago Mercantile Exchange (“CME”), as an alternative replacement rate for LIBOR.  Wesbanco may also continue to utilize the Wall Street Journal Prime Rate, the Treasury Rates, and other indexes as part of its lending program.  System and process updates are being made to enable the use of the 1M Term SOFR for new loan production by the end of 2021 in accordance with regulatory guidelines. At a date in the future, prior to the cessation of the publication of the one month LIBOR, Wesbanco will transition all remaining LIBOR based loans to the replacement index after notification to the impacted borrowers.

With respect to its back-to-back swap program, Wesbanco worked with its swap counterparty customers to institute and accept the International Swaps and Derivatives Association 2020 Interbank Offered Rate Fallbacks Protocol ("ISDA 2020 IBOR Protocol") to address LIBOR cessation in swap transactions.  Moreover, Wesbanco has initially chosen 1M Term SOFR as its replacement index for new loans in the bank’s back-to-back swap program.  The LIBOR transition committee, in consultation with market participants, expects the market for Term SOFR derivatives to be actively engaged prior to the end of 2021, allowing the program to meet the Agencies timeline of December 31, 2021.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The disclosures set forth in this item are qualified by the section captioned “Forward-Looking Statements” included in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report.

MARKET RISK

The primary objective of Wesbanco’s Asset/Liability Committee (“ALCO”) is to maximize net interest income within established policy parameters. This objective is accomplished through the management of balance sheet composition, market risk exposures arising from changing economic conditions and liquidity risk.

Market risk is defined as the risk of loss due to adverse changes in the fair value of financial instruments resulting from fluctuations in interest rates and bond prices.  Management considers interest rate risk to be Wesbanco’s most significant market risk. Interest rate risk is the exposure to adverse changes in net interest income due to changes in interest rates. The consistency of Wesbanco’s net interest income is largely dependent on effective management of interest rate risk.  As interest rates change in the market, rates earned on interest rate-sensitive assets and rates paid on interest rate-sensitive liabilities do not necessarily move concurrently.  Differing rate sensitivities may arise because fixed rate assets and liabilities may not have the same maturities, or because variable rate assets and liabilities differ in the timing and/or the percentage of rate changes.

Wesbanco’s ALCO is an executive management committee with Board representation, responsible for monitoring and managing interest rate risk within approved policy limits, utilizing earnings sensitivity simulation and economic value-at-risk models. These models are highly dependent on various assumptions, which change regularly as the balance sheet and market interest rates change. The key assumptions and strategies employed are analyzed, reviewed and documented at least quarterly by the ALCO.

The earnings sensitivity simulation model projects changes in net interest income resulting from the effects of changes in interest rates. Forecasting changes in net interest income requires management to make certain assumptions regarding loan and security prepayment rates, call dates, changes to deposit product betas and non-maturity deposit decay rates, which may not necessarily reflect the manner in which actual cash flows, yields, and costs respond to changes in market interest rates. Assumptions are based on historical experience, current market rates and economic forecasts, and are internally back-tested and periodically reviewed by a third-party consultant. The net interest income sensitivity results presented in Table 1, “Net Interest Income Sensitivity,” assumes that the balance sheet composition of interest sensitive assets and liabilities existing at the end of the period remains constant over the period being measured and also assumes that a particular change in interest rates is reflected uniformly across the yield curve, regardless of the duration of the maturity or re-pricing of specific assets and liabilities. Since the assumptions used in the model relative to changes in interest rates are uncertain, the simulation analysis may not be indicative of actual results.  In addition, this analysis does not consider actions that management might employ in response to changes in interest rates, as well as changes in earning asset and costing liability balances.

Interest rate risk policy limits are determined by measuring the anticipated change in net interest income over a twelve-month period, assuming immediate and sustained market interest rate increases and decreases of 100 - 300 basis points across the entire yield curve, as compared to a stable rate environment or base model.  Wesbanco’s current policy limits this exposure for the noted interest rate changes to a reduction of between 7.5% - 15%, or less, of net interest income from the stable rate base model over a twelve-month period.  The table below indicates Wesbanco’s interest rate sensitivity at September 30, 2021 and December 31, 2020, assuming the above-noted interest rate increases, as compared to a base model.  In the current interest rate environment, particularly for short-term rates, the 100 – 300 basis points decreasing changes for September 30, 2021 and December 31, 2020 are not shown due to the unrealistic and/or negative yield nature of the results.

TABLE 1. NET INTEREST INCOME SENSITIVITY

Immediate Change in	Percentage Change in
Interest Rates	Net Interest Income from Base over One Year		ALCO
(basis points)	September 30, 2021	December 31, 2020	Guidelines
+300	15.9%	15.3%	(15.0%)
+200	10.7%	10.3%	(10.0%)
+100	5.7%	5.5%	(7.5%)

Adjustments to relative sensitivities are due to the impact of the current lower rate and yield curve environment on base case net interest income and the related calculation of parallel rate shock changes in rising and falling rate scenarios. Additional differences typically result from changes in the various earning assets and costing liabilities mix and growth rates, as well as adjustments for various modeling assumptions. Generally, deposit betas utilized in modeling are estimated at more conservative percentages for both up and down rate scenarios than has been the Bank’s historical experience, as a result of both competitive factors in our markets and as public funds and institutional contract terms are renewed. Deposit betas, decay rates and loan prepayment speeds are adjusted periodically in our models for non-maturity deposits and loans. Indicated model asset sensitivity in rising rate scenarios may be less than anticipated due to slower prepayment speeds, rate floors, below forecast loan yields, spread compression between new asset yields and funding costs, mortgage-related extension risk and other factors. In a decreasing rate environment, asset sensitivity may have greater impact on the margin than currently modeled as prepayment speeds increase, customers refinance or request rate reductions on existing loans, estimated deposit betas do not perform as modeled, or for other reasons.  

54

In addition to the aforementioned parallel rate shock earnings sensitivity simulation model, the ALCO also reviews a “dynamic” forecast scenario to project net interest income over a rolling two-year time period.  This forecast is updated at least quarterly, incorporating revisions and updated assumptions into the model for estimated loan and deposit growth, expected balance sheet re-mixing strategies, changes in forecasted rates for various maturities, competitive market spreads for various products and other assumptions. Such modeling is directionally consistent with typical parallel rate shock scenarios, and it assists in predicting changes in forecasted outcomes and potential adjustments to management plans to assist in achieving earnings goals.

Wesbanco also periodically measures the economic value of equity (“EVE”), which is defined as the market value of tangible equity in various rate scenarios.  Generally, changes in the economic value of equity relate to changes in various assets and liabilities, changes in the yield curve, as well as changes in loan prepayment speeds and deposit decay rates.  The following table presents these results and Wesbanco’s policy limits as of September 30, 2021 and December 31, 2020. Changes in EVE sensitivity since year-end 2020 relate to the increase in market interest rates and their impact upon the fair values of earning assets and costing liabilities.

Immediate Change in	Percentage Change in
Interest Rates	Economic Value of Equity from Base over One Year		ALCO
(basis points)	September 30, 2021	December 31, 2020	Guidelines
+300	5.0%	13.4%	(30.0%)
+200	3.7%	10.6%	(20.0%)
+100	3.6%	7.1%	(10.0%)

The Bank has significant additional borrowing capacity with the FHLB of Pittsburgh, the Federal Reserve Bank of Cleveland and various correspondent banks, and may utilize these funding sources or interest rate swap strategies as necessary to lengthen liabilities, offset mismatches in various asset maturities and manage liquidity.  CDARS® and ICS® deposits also may be utilized for similar purposes for certain customers seeking higher-yielding instruments or maintaining deposit levels below FDIC insurance limits. Significant balance sheet strategies to assist in managing the net interest margin in the current interest rate environment include:

• increasing total loans, particularly commercial and home equity loans that have variable or adjustable features;

• selling a percentage of longer-term residential mortgage loan production into the secondary market;

• growing demand deposit account types to increase the relative portion of these account types to total deposits;

• employing back-to-back loan swaps for certain commercial loan customers desiring a term fixed-rate loan equivalent, with the Bank receiving a variable rate;

• adjusting terms for FHLB short-term maturing borrowings to balance asset/liability mismatches; or paying them off with excess liquidity

• using CDARS^®  and ICS^® deposit programs to manage funding needs and overall liability mix, and

• adjusting the size, mix or duration of the investment portfolio as part of liquidity and balance sheet management strategies.  

Management is aware of the significant effect that inflation or deflation has upon interest rates and ultimately upon financial performance.  Wesbanco’s ability to cope with inflation or deflation is best determined by analyzing its capability to respond to changing market interest rates, as well as its ability to manage the various elements of non-interest income and expense during periods of increasing or decreasing inflation or deflation. Wesbanco monitors the level and mix of interest-rate sensitive assets and liabilities through ALCO in order to reduce the impact of inflation or deflation on net interest income.  Management also controls the effects of inflation or deflation by conducting periodic reviews of the prices, costs and terms of its various products and services, as well as competitive factors, by approving new products and services or adjusting the terms and availability of existing products and services.  Over the last few months of the third quarter, inflation has been trending higher and has impacted the cost of labor and purchased goods and services.  Wesbanco is also monitoring the potential impact that inflation is having on multifamily properties as proposed rental rate caps and controls are put in place in areas across Wesbanco’s footprint.

55

ITEM 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES— Wesbanco’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) have concluded that Wesbanco’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended), based on their evaluation of these controls and procedures as of the end of the period covered by this Form 10-Q, are effective to ensure that information required to be disclosed by Wesbanco in the reports it files under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to Wesbanco’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

LIMITATIONS ON THE EFFECTIVENESS OF CONTROLS— Wesbanco’s management, including the CEO and CFO, does not expect that Wesbanco’s disclosure controls and internal controls will prevent all errors and all fraud. While Wesbanco’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their objective, no control system, no matter how well conceived and operated, can provide absolute assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls.

CHANGES IN INTERNAL CONTROLS— During the third quarter of 2021, the Company completed the conversion of its legacy core banking system into a new core banking platform.  This upgrade included enhancements to the loan and deposit areas, as well as digital banking and the general ledger, among others.  As a result of the conversion, there were certain changes to processes and procedures, which have materially affected, or are reasonably likely to have materially affected, the Company's internal control over financial reporting since management's last assessment of the Company's internal control over financial reporting, which was completed as of June 30, 2021.

There have been no other changes in the Company's internal control over financial reporting during the most recently completed quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

56

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Wesbanco is involved in various lawsuits, claims, investigations and proceedings, which arise in the ordinary course of business.  While any litigation contains an element of uncertainty, Wesbanco does not believe that a material loss related to such proceedings or claims pending or known to be threatened is reasonably possible.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

As of September 30, 2021, Wesbanco had one active stock repurchase plan. It was approved by the Board of Directors on August 26, 2021 for 3.2 million shares and provides for shares to be repurchased for general corporate purposes, which may include a subsequent resource for potential acquisitions, shareholder dividend reinvestment and employee benefit plans. The timing, price and quantity of purchases are at the discretion of Wesbanco, and the plan may be discontinued or suspended at any time.

Other repurchases in the third quarter included those for the KSOP and dividend reinvestment plans.

The following table presents the monthly share purchase activity during the quarter ended September 30, 2021:

Period	Total Number of Shares Purchased (1)		Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans (2)		Maximum Number of Shares that May Yet Be Purchased Under the Plans (3)
Balance at June 30, 2021								1,899,216

Summary of Significant Accounting Policies

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020.

Wesbanco’s interim financial statements have been prepared following the significant accounting policies disclosed in Note 1 of the Notes to the Consolidated Financial Statements of its 2020 Annual Report on Form 10-K filed with the Securities and Exchange Commission.  In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly Wesbanco’s financial position and results of operations for each of the interim periods presented. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on Wesbanco’s net income and stockholders’ equity. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year.

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

ASU 2020-04 and ASU 2021-01 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 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, 2022, and can be adopted at any time during this period. Wesbanco has not yet adopted either ASU, but has implemented a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR, and 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.

ASU 2019-12 Income Taxes (Topic 740)

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP for: (1) franchise taxes that are partially based on income; (2) transactions with a government that result in a step-up in the tax basis of goodwill; (3) separate financial statements of legal entities that are not subject to tax; and (4) enacted changes in tax laws in interim periods. For Wesbanco, this update was effective beginning January 1, 2021. The adoption of this pronouncement did not have a material impact on the financial statements.

As of September 30, 2021 and 2020, respectively, 534,961 and 729,985 options to purchase shares were not included in the computation of net income per diluted share for the three months ended September 30, 2021 and 2020 because the exercise price was greater than the average market price of a common share, therefore, the effect would be antidilutive. As of September 30, 2021 and 2020, respectively, 534,961 and 536,761 options to purchase shares were not included in the computation of net income per diluted share for the nine months ended September 30, 2021 and 2020 on the same basis.

As of September 30, 2021, no shares related to the 2021, 2020 and 2019 total shareholder return plans were included in the calculation because the effect would be antidilutive. On the same basis, as of September 30, 2020, no shares related to the 2020, 2019 and 2018 total shareholder return plans were included in the calculation.

In addition, performance-based restricted stock totaling 61,267 and 27,371 shares were estimated to be awarded as of September 30, 2021 and September 30, 2020, respectively, and are included in the diluted calculation for both the three and nine months ended.

(1) Total held-to-maturity debt securities are presented on the balance sheet net of their allowance for credit losses totaling $0.3 million at September 30, 2021 and December 31, 2020, respectively.

At September 30, 2021 and December 31, 2020, 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 $10.5 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 $13.5 million and $13.0 million at September 30, 2021 and December 31, 2020, respectively.

The following table presents the amortized cost and fair value of available-for-sale and held-to-maturity debt securities by contractual maturity date at September 30, 2021.  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.

Securities with an aggregate fair value of $2.0 billion and $1.8 billion at September 30, 2021 and December 31, 2020, respectively, were pledged as security for public and trust funds, and securities sold under agreements to repurchase. Proceeds from the sale of available-for-sale securities were $0 and $226.1 million for the nine months ended September 30, 2021 and 2020, respectively.  Net unrealized gains on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of September 30, 2021 and December 31, 2020 were $18.5 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 three and nine months ended September 30, 2021 and 2020, respectively.  All gains and losses presented in the table below are included in the net securities gains 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.

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 $7.1 million and $5.3 million as of September 30, 2021 and December 31, 2020, 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 nine months ended September 30, 2021 and 2020:

Unrealized losses on debt securities in the table above represents 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; 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 Federal Home Loan Bank (“FHLB”) of Pittsburgh stock totaling $17.0 million and $34.0 million at September 30, 2021 and December 31, 2020, 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

NOTE 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 fee income was $1.7 million and $6.2 million at September 30, 2021 and December 31, 2020, respectively.  At September 30, 2021 and December 31, 2020, respectively, the balance also included $10.4 million and $13.8 million of net deferred fee income from SBA Payroll Protection Program (“PPP”) loans. The un-accreted discount on purchased loans from acquisitions was $28.9 million at September 30, 2021 and $39.4 million at December 31, 2020.

The allowance for credit losses under the current expected credit losses methodology (“CECL”) is calculated utilizing the probability of default (“PD”) / loss given default (“LGD”), which is then discounted to net present value. PD is the probability the asset will default within a given time frame and LGD is the percentage of the asset not expected to be collected due to default. The primary macroeconomic drivers of the quantitative model include forecasts of national unemployment and interest rates, as well as modeling adjustments for changes in prepayment speeds, loan risk grades, portfolio mix, concentrations and loan growth. For the calculation as of September 30, 2021, the one-year forecast was based upon a blended rate from two nationally-recognized published economic forecasts through September 30, 2021, and is primarily driven by the national unemployment and interest rate spread forecasts. Wesbanco’s blended forecast of national unemployment, at quarter end, was projected to peak at 4.7% in the fourth quarter, and subsequently decrease to an average of 4.0% over the remainder of the forecast period. The calculation utilized a one-year reversion period back to the Company’s historical loss rate by loan classification.  Included in the qualitative factors were COVID-19 pandemic factors related to the transient credit risk not included within the quantitative model calculation, adjusted to Wesbanco’s regional footprint, deferred interest on modified loans, and hospitality industry concentration.  As of September 30, 2021, accrued interest receivable for loans was $48.1 million. 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 $0.1 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 September 30, 2021, accrued interest receivable related to COVID-19 loan modifications as permitted under the CARES Act was $23.1 million.

The following tables summarize changes in the allowance for credit losses applicable to each category of the loan portfolio:

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.  

Commercial and industrial (“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.

Residential real estate, home equity and consumer loans are not assigned internal risk grades other than as required by regulatory guidelines that are based primarily on the age of past due loans.  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 was $29.4 million at September 30, 2021 and $27.7 million at December 31, 2020, of which $6.2 million and $4.1 million were accruing, for each period, respectively.  These loans are not included in the tables above.  In addition, $20.4 million and $28.7 million of unfunded commercial loan commitments, are also not included in the tables above at September 30, 2021 and December 31, 2020, respectively.

As of September 30, 2021 and December 31, 2020, there were no TDRs greater than $1.0 million. 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 no unfunded commitments to debtors whose loans were classified as nonperforming as of September 30, 2021  and $0.9 million as of   December 31, 2020.

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 3,553 loans totaling $2.2 billion, of which $132.8 million remain in their deferral period as of September 30, 2021.  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.  On December 27, 2020, the Economic Aid to Hard-Hit Small Businesses, Nonprofits and Venues Act (“Economic Aid Act”) was signed into law and among other things, extended the relief granted by the CARES Act for TDRs, initially slated to end on December 31, 2020, by one year to December 31, 2021.

Derivatives and Hedging Activities

NOTE 5. 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 Wesbanco Bank, Inc.’s (the “Bank”) assets and liabilities are equally distributed but also have similar maturities.

Loan Swaps

Wesbanco executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies.  Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that Wesbanco executes with a third party, such that Wesbanco minimizes its net risk exposure resulting from such transactions.  As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements of ASC 815, changes in the fair value of both the customer swaps and the offsetting third-party swaps are recognized directly in earnings.  As of September 30, 2021 and December 31, 2020, Wesbanco had 130 and 112 customer interest rate swaps with an aggregate notional amount of $696.0 million and $649.9 million, respectively, related to this program.  Wesbanco recognized income for the related swap fees of $0.4 million and $0.9 million for the three months ended September 30, 2021 and 2020, respectively and $3.3 million and $7.0 million for the nine months ended September 30, 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 September 30, 2021 and December 31, 2020, Wesbanco had 14 and 12, risk participation-in agreements with an aggregate notional amount of $132.4 million and $101.1 million, respectively.  As of September 30, 2021 and December 31, 2020, Wesbanco had one risk participation-out agreement with an aggregate notional amount of $9.9 million and $10.0 million, respectively.

Mortgage Loans Held for Sale and Loan 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 loan commitment and the closing of the loan.  The total balance of forward TBA contracts entered into was $65.2 million and $183.5 million at September 30, 2021 and December 31, 2020, 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 paying 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 a qualifying hedging relationship 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 September 30, 2021 and December 31, 2020:

Credit-risk-related Contingent Features

Wesbanco has agreements with its derivative counterparties that contain a provision, which provides that if Wesbanco defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Wesbanco could also be declared in default on its derivative obligations.

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.

Wesbanco had minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral with a market value of $58.0 million as of September 30, 2021.  If Wesbanco had breached any of these provisions at September 30, 2021, 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.

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair Value Measurement

NOTE 7. 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 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 sheet with any resulting gain or loss recorded in current period earnings as other income and other expense.

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 sheet with any resulting gain or loss recorded in current period’s 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.

Individually-evaluated loans: Individually-evaluated loans are carried at the amortized cost basis less the specific allowance calculated under CECL. Individually-evaluated loans are calculated using a cost basis approach 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, and 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 statement 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 September 30, 2021 and December 31, 2020:

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.  There were no significant transfers between level 1, 2 or 3 for the three and nine months ended September 30, 2021 or for the year ended December 31, 2020.  

The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which Wesbanco has utilized level 3 inputs to determine fair value:

The following methods and assumptions were used to measure the fair value of financial instruments recorded at cost on Wesbanco’s consolidated balance sheets:

Cash and due from banks:  The carrying amount for cash and due from banks is a reasonable estimate of fair value.

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.

Revenue Recognition [Abstract]

Revenue Recognition

NOTE 8. 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 slightly 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 per the signed agreement between Wesbanco and the buyer.

The following table summarizes the point of revenue recognition and the income recognized for each of the revenue streams for the three and nine months ended September 30, 2021 and 2020, respectively:

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

NOTE 10. 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 $7.3 million and $9.5 million at September 30, 2021 and December 31, 2020, 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 $0.1 million and $0.2 million as of September 30, 2021 and December 31, 2020, respectively.

Contingent obligations to purchase loans funded by other entities include credit card guarantees, loans sold with recourse as well as obligations to the FHLB.  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:

	September 30,		December 31,
(unaudited, in thousands)	2021		2020
Lines of credit	$	2,801,461	$	2,510,011
Loans approved but not closed		449,869		381,180
Overdraft coverage		381,243		154,322
Letters of credit		29,234		53,788
Contingent obligations and other guarantees		117,682		126,984

Contingent Liabilities — Wesbanco recognized $2.6 million of legal settlement costs in the third quarter in which settlement is subject to final court approval. 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.

Business Segments

NOTE 11. BUSINESS SEGMENTS

Wesbanco operates two reportable segments: community banking and 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 managed or held in custody by the trust and investment services segment was approximately $5.5 billion and $4.6 billion at September 30, 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 Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of presentation

Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020.

Wesbanco’s interim financial statements have been prepared following the significant accounting policies disclosed in Note 1 of the Notes to the Consolidated Financial Statements of its 2020 Annual Report on Form 10-K filed with the Securities and Exchange Commission.  In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly Wesbanco’s financial position and results of operations for each of the interim periods presented. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on Wesbanco’s net income and stockholders’ equity. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year.

Recent accounting pronouncements

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

ASU 2020-04 and ASU 2021-01 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 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, 2022, and can be adopted at any time during this period. Wesbanco has not yet adopted either ASU, but has implemented a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR, and 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.

ASU 2019-12 Income Taxes (Topic 740)

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP for: (1) franchise taxes that are partially based on income; (2) transactions with a government that result in a step-up in the tax basis of goodwill; (3) separate financial statements of legal entities that are not subject to tax; and (4) enacted changes in tax laws in interim periods. For Wesbanco, this update was effective beginning January 1, 2021. The adoption of this pronouncement did not have a material impact on the financial statements.
