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, 2015.

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 2015 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. 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 — In March 2016, the Financial Accounting Standards Board (the “FASB”) issued an Accounting Standards Update (“ASU”) (ASU 2016-09) that will require all income tax effects of stock awards to be recognized in the income statement when the awards vest or are settled. It also will allow an employer to repurchase more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-07 that eliminates the requirement to retrospectively apply the equity method in previous periods when an investor initially obtains significant influence over an investee. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2016, and requires prospective adoption. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02 that will require entities to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The principal difference from previous guidance is that the lease assets and lease liabilities arising from operating leases were not previously recognized in the balance sheet. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. WesBanco is currently evaluating the impact of the adoption of this pronouncement on its Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01 that will require entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicability exception. The standard does not change the guidance for classifying and measuring investments in debt securities and loans. Entities will have to record changes in instrument-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In September 2015, the FASB issued ASU 2015-16 which eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The acquirer still must disclose the amounts and reasons for adjustments to the provisional amounts. The acquirer also must disclose, by line item, the amount of the adjustment reflected in the current-period income statement that would have been recognized in previous periods if the adjustment to provisional amounts had been recognized as of the acquisition date. Alternatively, an acquirer may present those amounts separately on the face of the income statement. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2015, including interim periods with those fiscal years. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In May 2015, the FASB issued ASU 2015-07 related to disclosures for investments in certain entities that calculate net asset value (NAV) per share (or its equivalent). This update removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient and modifies certain disclosure requirements. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2015, and requires retrospective adoption. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-05 that provides guidance on when to account for a cloud computing arrangement as a software license. The guidance applies only to internal-use software that a customer obtains access to in a hosting arrangement if both of the following criteria are met: (1) The customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty, (2) it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In February 2015, the FASB issued ASU 2015-02 that revised the consolidation model, requiring reporting entities to reevaluate whether they should consolidate certain legal entities under the revised model. The amendments in this update modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities, and eliminate the presumption that a general partner should consolidate and affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee

7

arrangements and related party relationships. The pronouncement also provides for a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In May 2014, the FASB issued ASU 2014-09 related to the recognition of revenue from contracts with customers. The new revenue pronouncement creates a single source of revenue guidance for all companies in all industries and is more principles-based than current revenue guidance. The pronouncement provides a five-step model for a company to recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The five steps are, (1) identify the contract with the customer, (2) identify the separate performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the separate performance obligations and (5) recognize revenue when each performance obligation is satisfied. The pronouncement was originally effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016 using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. Early adoption was not permitted. On July 9, 2015, the FASB approved a one-year deferral of the effective date of the update. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. Early adoption is now permitted as of the original effective date for interim and annual reporting periods in fiscal years beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08 which amends the principal versus agent guidance in the revenue standard. WesBanco is currently evaluating the impact of the adoption of this pronouncement on its Consolidated Financial Statements.

NOTE 2. EARNINGS PER COMMON SHARE

Earnings per common share are calculated as follows:

	For the Three Months Ended
	March 31,
(unaudited, in thousands, except shares and per share amounts)	2016		2015
Numerator for both basic and diluted earnings per common share:
Net income	$	22,874	$	13,887
Denominator:
Total average basic common shares outstanding		38,386,983		34,393,137
Effect of dilutive stock options and warrant		15,333		85,198
Total diluted average common shares outstanding		38,402,316		34,478,335
Earnings per common share - basic	$	0.60	$	0.40
Earnings per common share - diluted	$	0.60	$	0.40

Stock options representing shares of 167,750 and 0 for the three months ended March 31, 2016 and 2015, respectively, were not included in the computation of diluted earnings per share, because to do so would have been anti-dilutive. Contingently issuable shares awarded under the total shareholder return plan were not included in the diluted computation for three months ended March 31, 2016, because to do so would have been anti-dilutive.

On February 10, 2015, WesBanco issued 9,178,531 shares to complete its acquisition of ESB. These shares are included in average shares outstanding beginning on that date.

Securities with aggregate fair values of $1.1 billion and $1.0 billion at March 31, 2016 and December 31, 2015, 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 $15.0 million and $560.7 million for the three months ended March 31, 2016 and 2015, respectively. Net unrealized gains (losses) on available-for-sale securities included in accumulated other comprehensive income net of tax, as of March 31, 2016 and December 31, 2015 were $8.1 million and ($4.2) million, respectively.

Unrealized losses on debt securities in the tables represent temporary fluctuations resulting from changes in market rates in relation to fixed yields. Unrealized losses in the available-for-sale portfolio are accounted for as an adjustment, net of taxes, to other comprehensive income in shareholders’ equity.

WesBanco does not believe the securities presented above are impaired due to reasons of credit quality, as substantially all debt securities are rated above investment grade and all are paying principal and interest according to their contractual terms. WesBanco does not intend to sell, nor is it more likely than not that it will be required to sell, loss position securities prior to recovery of their cost, and therefore, management believes the unrealized losses detailed above are temporary and no impairment loss relating to these securities has been recognized.

Securities that do not have readily determinable fair values and for which WesBanco does not exercise significant influence are carried at cost. Cost method investments consist primarily of FHLB of Pittsburgh stock totaling $45.4 million and $45.5 million at March 31, 2016 and December 31, 2015, 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.

⁽¹⁾  Commercial loans greater than $1 million that are reported as non-accrual or as a troubled debt restructuring (“TDR”) are individually evaluated for impairment.

WesBanco maintains an internal loan grading system to reflect the credit quality of commercial loans. Commercial loan risk grades are determined based on an evaluation of the relevant characteristics of each loan, assigned at the inception of each loan 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 reliability and sustainability of the primary source of repayment and overall financial strength of the borrower. This includes an analysis of cash flow available to repay debt, profitability, liquidity, leverage, and overall financial trends. Other factors include management, industry or property type risks, an assessment of secondary sources of repayment such as collateral or guarantees, other terms and conditions of the loan that may increase or reduce its risk, and economic conditions and other external factors that may influence repayment capacity and financial condition.

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 net rental income generated by the property to service the debt, the type, quality, industry and mix of tenants, and the terms of leases, but also considers the overall financial capacity of the investors and their experience in owning and managing investment property. The risk grade assigned to owner-occupied commercial real estate and commercial and industrial loans is based primarily on historical and projected earnings, the adequacy of operating cash flow to service all of the business’ debt, and the capital resources, liquidity and leverage of the business, but also considers the industry in which the business operates, the business’ specific competitive advantages or disadvantages, the quality and experience of management, and external influences on the business such as economic conditions. Other factors that are considered for commercial and industrial loans include the type, quality and marketability of non-real estate collateral and whether the structure of the loan increases or reduces its risk. The type, age, condition, location and any environmental risks associated with a property are also considered for all types of commercial real estate. The overall financial condition and repayment capacity of any guarantors is also evaluated to determine the extent to which they mitigate other risks of the loan. The following paragraphs provide descriptions of risk grades that are applicable to commercial real estate and commercial and industrial loans.

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 or compromised loans are currently protected but have weaknesses, which, if not corrected, may be inadequately protected at some future date. These loans represent an unwarranted credit risk and would generally not be extended in the normal course of lending. Specific issues

12

which may warrant this grade include declining financial results, increased reliance on secondary sources of repayment or guarantor support and adverse external influences that may negatively impact the business or property.

Substandard and doubtful loans are equivalent to the classifications used by banking regulators. Substandard loans are inadequately protected by the current repayment capacity and equity of the borrower or collateral pledged, if any. Substandard loans have one or more well-defined weaknesses that jeopardize their repayment or collection in full. These loans may or may not be reported as non-accrual. Doubtful loans have all the weaknesses inherent to a substandard loan with the added characteristic that full repayment is highly questionable or improbable on the basis of currently existing facts, conditions and collateral values. However, recognition of loss may be deferred if there are reasonably specific pending factors that will reduce the risk if they occur.

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 were $16.0 million at March 31, 2016 and $15.8 million at December 31, 2015, of which $2.1 and $3.1 million were accruing, for each period, respectively. The aggregate amount of residential real estate, home equity and consumer loans classified as substandard are not included in the tables above.

Acquired Loans - Loans acquired with deteriorated credit quality at March 31, 2016 and December 31, 2015 were $7.7 million and $9.3 million, respectively, while the non-accretable difference was $8.0 million and $9.1 million, respectively. At March 31, 2016 and December 31, 2015 no allowance for loan losses has been recognized related to the acquired impaired loans, as estimates of future cash flows on these loans have not been negatively impacted.

The following table provides changes in accretable yield for loans acquired with deteriorated credit quality:

As of March 31, 2016, 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 three months. WesBanco had no unfunded commitments to debtors whose loans were classified as impaired as of March 31, 2016 and $0.2 million as of December 31, 2015.

NOTE 6. 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:

Securities available-for-sale: The fair value of securities available-for-sale 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. Certain equity securities that are lightly traded in over-the-counter markets are classified as level 2 in the fair value hierarchy, as quoted market prices may not be available on the fair value measurement date. 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.

We may be required from time to time to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower of cost or market accounting or write-downs of individual assets.

Impaired loans: Impaired loans are carried at the lower of cost or the fair value of the collateral for collateral-dependent loans. Collateral may be in the form of real estate or business assets including equipment, inventory and accounts receivable. The use of independent appraisals, discounted cash flow models and management’s best judgment are significant inputs in arriving at the fair value measure of the underlying collateral and impaired loans are therefore classified within level 3 of the fair value hierarchy.

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.

Loans held for sale: Loans held for sale are carried, in aggregate, at the lower of cost or fair value. 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.

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 transfers between level 1, 2 or 3 for the three months ended March 31, 2016 or for the year ended December 31, 2015.

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.

Securities held-to-maturity: Fair values for securities held-to-maturity are determined in the same manner as securities available-for-sale which is 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.

Bank-owned life insurance: The carrying value of bank-owned life insurance represents the net cash surrender value of the underlying insurance policies, should these policies be terminated. Management believes that the carrying value approximates its fair value.

21

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.

Junior subordinated debt owed to unconsolidated subsidiary trusts: Due to the pooled nature of these instruments, 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. 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 $0.6 million as of both March 31, 2016 and December 31, 2015, and is included in other liabilities on the Consolidated Balance Sheets.

Letters of credit are conditional commitments issued by banks to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including normal business activities, bond financing and similar transactions. Letters of credit are considered guarantees. The liability associated with letters of credit was $0.2 million as of both March 31, 2016 and December 31, 2015.

Contingent obligations to purchase loans funded by other entities include affordable housing plan guarantees, credit card guarantees and mortgages sold into the secondary market with recourse. Affordable housing plan guarantees are performance guarantees for various building project loans. The guarantee amortizes as the loan balances decrease. Credit card guarantees are credit card balances not owned by WesBanco, whereby the Bank guarantees the performance of the cardholder. Certain mortgages sold with recourse obligate WesBanco to repurchase mortgages sold if the borrower exceeds certain delinquency metrics within the first year.

The following table presents total commitments to extend credit, guarantees and various letters of credit outstanding:

(unaudited, in thousands)	March 31, 2016		December 31, 2015
Lines of credit	$	1,210,101	$	1,159,769
Loans approved but not closed		213,959		234,599
Overdraft limits		105,774		106,252
Letters of credit		22,743		27,408
Contingent obligations to purchase loans funded by other entities		18,779		18,079

Contingent Liabilities — WesBanco is a party to various legal and administrative proceedings and claims. While any litigation contains an element of uncertainty, management does not believe that a material loss related to such proceedings or claims pending or known to be threatened is reasonably possible.

NOTE 9. 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 $3.6 billion and $3.9 billion at March 31, 2016 and 2015, 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.

NOTE 10. SUBSEQUENT EVENTS

On May 3, 2016, WesBanco and Your Community Bankshares, Inc. (“YCB”), a bank holding company headquartered in New Albany, Indiana with $1.6 billion in assets and 36 branches, jointly announced that a definitive Agreement and Plan of Merger was executed providing for the merger of YCB with and into WesBanco. The transaction currently is valued at approximately $221.0 million. Under the terms of the Agreement and Plan of Merger, which has been approved by the board of directors of both companies, WesBanco will exchange a combination of its common stock and cash for YCB common stock. YCB shareholders will be entitled to receive 0.964 shares of WesBanco common stock and cash in the amount of $7.70 per share for each share of YCB common stock for a total value of approximately $39.05 per share at the date of announcement. The receipt by YCB shareholders of shares of WesBanco common stock in exchange for their shares of YCB common stock is anticipated to qualify as a tax-free exchange. The acquisition is subject to the approvals of the appropriate banking regulatory authorities and the shareholders of YCB. It is expected that the transaction will be completed in the third or fourth quarter of 2016.

RESULTS OF OPERATIONS

EARNINGS SUMMARY

Net income for the three months ended March 31, 2016 was $22.9 million or $0.60 per diluted share compared to $13.9 million or $0.40 per diluted share for the first quarter of 2015. Net income excluding after-tax merger-related expenses (non-GAAP measure), increased 13.2% to $22.9 million compared to $20.2 million for the first quarter of 2015, while diluted earnings per share, excluding after-tax merger-related expenses (non-GAAP measure), totaled $0.60, compared to $0.59 per share for the first quarter of 2015.

(1) Non-GAAP net income excludes after-tax 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 increased $4.9 million or 8.9% in the first quarter of 2016 compared to the same quarter of 2015 due to an 18.7% increase in average earning assets, primarily through the acquisition, and through a 6.6% increase in average loan balances, partially offset by a 30 basis point decrease in the net interest margin. The net interest margin decreased to 3.29% in the first quarter, compared to 3.59% in same quarter of 2015. The decrease in the net interest margin is primarily due to a change in the mix of securities to total average earning assets from 28.9% in 2015 to 31.6% in 2016, a 15 basis point decline in the average rate earned on securities due to lower yields from a restructuring of the ESB portfolio in 2015 and a decrease of 17 basis points for total loans due to repricing of existing loans at lower spreads and competitive pricing on new loans. The lower spreads were due to the continued low interest rate environment with a relatively flat yield curve. Mitigating this reduction is the aforementioned loan growth, which improves asset yields as the average rate on loans is higher than the average rate on securities. Funding costs increased 9 basis points in the first quarter compared to the same quarter in 2015, primarily due to an increase in FHLB borrowings to 17.2% of interest bearing liabilities from 6.4% in 2015 with an associated 51 basis point increase in the average rate on these borrowings as the term increased from short to medium. Average deposits in the first quarter increased by 6.0%, primarily due to the acquisition which closed midway through the first quarter of 2015. The rate on interest bearing deposits decreased 2 basis points to 0.32% due to the maturity of higher cost CDs. In addition, growth in average deposits occurred in lower cost categories of interest and non-interest bearing demand deposits and savings deposits, while CDs decreased by 3.3%.

The provision for credit losses increased to $2.3 million in the first quarter of 2016 compared to $1.3 million in the first quarter of 2015 due to loan growth, but decreased 10.1% from the fourth quarter of 2015. Net charge-offs for the quarter as a percentage of average portfolio loans of 0.12% decreased from 0.16% in the first quarter of 2015 and from 0.20% in the fourth quarter of 2015.

For the first quarter of 2016, non-interest income increased $1.2 million or 6.6% compared to the 2015 first quarter. Service charges on deposits increased $0.3 million or 8.2% from the addition of ESB and adjustments to the fee schedule last year. Electronic banking fees increased $0.3 million or 8.4% from increases in transaction volume. Bank-owned life insurance decreased by $0.3 million primarily due to death benefits received in the first quarter of 2015. Net gains on sales of mortgage loans increased $0.3 million from a larger percentage of originations being sold in the secondary market. Trust fees decreased $0.3 million or 5.7% compared to the first quarter of last year from market declines, but increased 8.9% compared to the fourth quarter of last year primarily due to higher tax return preparation fees. Net securities gains increased by $1.1 million in the first quarter of 2016 compared to the first quarter of 2015, primarily due to realized gains resulting from calls on agency securities in the 2016 quarter.

The following paragraph on non-interest expense excludes merger-related expenses of $9.7 million in the first quarter of 2015. There were no merger-related expenses in the first quarter of 2016. Non-interest expense in the first quarter of 2016 grew $1.6 million or 3.7%, compared to the same quarter in 2015, partially due to the ESB acquisition. With net revenue growth of 8.3%, this positive operating leverage helped to improve the efficiency ratio in 2016 to 55.52% from 58.24% in the first quarter of 2015. Salaries and wages increased $0.8 million or 4.5%, due to a 3.8% increase in average full-time equivalent employees from the merger, routine annual adjustments to compensation and increased bonus and stock compensation expense. Employee benefits expense decreased $0.2 million, primarily from decreased health insurance costs. Equipment costs increased $0.5 million related to continuous improvements in computer system and software infrastructure, and origination and customer support systems. FDIC insurance expense increased $0.3 million due to the increased size of the balance sheet. Amortization of intangible assets increased $0.2 million from additional ESB intangible assets related to core deposits and non-compete agreements.

The provision for federal and state income taxes was $8.7 million in 2016 compared to $4.5 million in the first quarter of 2015. The increase in income tax expense was primarily due to a $13.2 million increase in pre-tax income, higher anticipated pre-tax income for 2016 and a $0.5 million benefit in 2015 relating to the completion of an IRS audit which closed the 2011 and 2012 tax years, all of which caused a higher effective tax rate of 27.5% for 2016 compared to 24.6% in the first quarter of 2015.

NET INTEREST INCOME

	For the Three Months Ended
	March 31,

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 (deposits and short and long-term borrowings). Net interest income is affected by the general level 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 increased $4.9 million or 8.9% in the first quarter of 2016 compared to the same quarter of 2015 due to an 18.7% increase in average earning assets, primarily through the ESB acquisition which closed midway through the first quarter of 2015, and through a 6.6% increase in average portfolio loan balances. The increase was partially offset by a 30 basis point decrease in the net interest margin. Total average deposits increased by $345.5 million or 6.0% as most major categories within deposits increased, while certificates of deposit, which have the highest interest cost among interest bearing deposits, decreased by $53.5 million or 3.3%. The lower-cost and non-interest bearing deposit increases were the result of marketing campaigns, customer incentives, wealth management and business initiatives as well as deposits from Marcellus and Utica shale gas bonus and royalty payments. The net interest margin decreased 30 basis points to 3.29% in the first quarter of 2016 from 3.59% in the same period of 2015. The reduction is primarily due to asset and liability mix shifts post-ESB, coupled with declining average yields on the securities and loan portfolios. Overall funding costs increased 9 basis points from the first quarter of 2015 due to higher balances of FHLB borrowings, and were slightly offset by a 2 basis point reduction in the cost of interest bearing deposits.

Interest income increased in the first quarter of 2016 by $7.2 million or 12.0% compared to the same period in 2015 due to the higher average balances of earning assets from both the ESB acquisition and organically, partially offset by lower yields. Rates decreased 17 basis points in the first quarter on average loan balances due to repricing of existing loans at lower spreads and competitive pricing on new loans. The lower spreads were due to the continued low interest rate environment with a relatively flat yield curve. However, the increase in average loan balances helped to mitigate the effect of the lower rates, as rates earned on loans are higher than those on securities. In the first quarter of 2016, average loans represented 67.0% of average earning assets, a decrease compared to 70.3% in the same quarter of 2015 due to the ESB acquired loan portfolio being smaller than the acquired investment portfolio. Total securities yields decreased by 15 basis points in the first quarter of 2016 from the same period in 2015 due to the lower yielding ESB acquired investment portfolio, net of sales, and the reinvestment of higher-rate calls and maturities at current lower available interest rates. Within the investment portfolio, the average rate declined on taxable and tax-exempt securities by 10 and 52 basis points, respectively, from the first quarter of 2015, offset somewhat by the aforementioned higher average balances in each category. The average balance of tax-exempt securities, which provide the highest yield within securities, increased 43.2% or $190.9 million over the last year, and were 26.3% of total average securities in the first quarter of 2016 compared to 23.9% in the first quarter of 2015, which helped to mitigate the 52 basis point decline in yield. Taxable securities balances increased by $360.2 million or 25.6% from the first quarter of 2015 as a significant portion of the acquired securities consisted of 10-15 year residential mortgage pools. Shorter-term mortgage pools reduce the average life of the portfolio, particularly for the portion accounted for as available-for-sale, positioning the Bank for possible future increases in interest rates, while maintaining required levels of pledgeable securities.

Portfolio loans increased $262.7 million or 5.4% in the twelve months ended March 31, 2016 as originations continued to outpace paydowns. Loan growth was achieved through $452.5 million in loan originations in the first quarter compared to $366.3 million in the first quarter of 2015. Loan growth was driven by increased business activity, additional commercial personnel in our core urban markets, focused calling efforts, additional market coverage from the ESB acquisition and improvement in loan origination processes.

        Interest expense increased $2.3 million or 43.0% in the first quarter of 2016 compared to the same period in 2015 primarily due to increases in both the average balance and rate paid on FHLB borrowings. The increases in FHLB borrowings were offset slightly by a decrease in the rate paid on deposits and increases in low cost average deposit balances, as non-interest bearing demand, interest bearing demand and savings deposits increased 12.8%, 14.2% and 12.6%, respectively, while average money market accounts and CDs decreased 1.9% and 3.3%, respectively. Total average interest bearing liabilities increased $882.0 million or 17.1% in the first quarter due to deposits from the ESB acquisition and increased medium-term FHLB borrowings. The average rate increased 9 basis points in the first quarter of 2016 compared to the same period in 2015. Rates paid on interest bearing deposits declined by 2 basis points to 0.32% in the first quarter due to a decline in rates paid on CDs, as a result of management reducing offered rates and the repricing, through purchase accounting, of acquired CDs on the acquisition date at lower market rates. The average rate paid on CDs declined by 3 basis points from the first quarter of 2015, while the rates paid on other deposit types remained nearly unchanged. The average balance of CDs also decreased $53.5 million or 3.3% from the first quarter of 2015. WesBanco continues to focus on reducing rate offerings and growing customers with multiple banking relationships, as opposed to single service certificate of deposit customers. In addition, non-interest bearing demand deposits increased to 21.3% of total average deposits in the first quarter of 2016 compared to 20.1% in the

29

same period of 2015. Average FHLB borrowings increased by $709.4 million or 213.9% in 2016, due to normal liquidity needs. In the first quarter of 2016, FHLB borrowings were 17.2% of interest bearing liabilities as compared to 6.4% in 2015. The rate on average FHLB borrowings also increased in the first quarter of 2016 by 51 basis points as the average term length increased from short to medium, causing most of the increase in cost of funds along with re-pricing on variable rate, LIBOR-based junior subordinated debt.

PROVISION FOR CREDIT LOSSES

The provision for credit losses is the amount to be added to the allowance for credit losses after net charge-offs have been deducted to bring the allowance to a level considered appropriate to absorb probable losses in the loan portfolio. The provision for credit losses also includes the amount to be added to the reserve for loan commitments to bring that reserve to a level considered appropriate to absorb probable losses on unfunded commitments. The provision for credit losses increased to $2.3 million in the first quarter of 2016 compared to $1.3 million in the first quarter of 2015 due to loan growth, but decreased 10.1% from the fourth quarter of 2015. Net charge-offs for the quarter as a percentage of average portfolio loans of 0.12% decreased from 0.16% in the first quarter of 2015 and from 0.20% in the fourth quarter of 2015. Non-performing loans (including TDRs) as well as criticized and classified loans, improved as a percentage of total portfolio loans from the first quarter of 2015. (Please see the Allowance for Credit Losses 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. 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 first quarter of 2016, non-interest income increased $1.2 million or 6.6% compared to the 2015 first quarter. The increase was primarily due to net securities gains, which increased $1.1 million compared to the first quarter of 2015 resulting from calls on certain agency securities during the first quarter of 2016. Additionally, the first quarter of 2016 included the operating results from the ESB acquired branches for the entire quarter, whereas the first quarter of 2015 included ESB results beginning on February 10, 2015, the date of the acquisition.

Trust fees decreased $0.3 million or 5.7% from the first quarter of last year as assets under management decreased due to overall market declines despite customer and revenue development initiatives. Total trust assets were down 7.7% from $3.9 billion at March 31, 2015 to $3.6 billion at March 31, 2016, but were relatively unchanged from December 31, 2015. At March 31, 2016, trust assets include managed assets of $2.9 billion and non-managed (custodial) assets of $0.7 billion. Assets managed for the WesMark Funds, a proprietary group of mutual funds that is advised by WesBanco’s trust and investment services group, were $893.7 million as of March 31, 2016 and $961.0 million at March 31, 2015 and are included in trust managed assets.

Service charges on deposits increased $0.3 million or 8.2% for the quarter compared to the first quarter of 2015 due to the larger customer deposit base from the addition of ESB and adjustments to the fee schedule last year.

Electronic banking fees, which include debit card interchange fees, continued to grow, increasing $0.3 million or 8.4% compared to the first quarter of 2015, due to a higher volume of debit card transactions from the ESB acquisition and WesBanco’s legacy customers. The volume increase is due to marketing and process initiatives as well as a higher percentage of customers using these products.

Net securities brokerage revenue decreased $0.2 million from the first quarter of 2015 due to turnover in certain producing staff positions and lower Marcellus and Utica gas lease and royalty payments in the region, despite additional market coverage in the expanded western Pennsylvania market from the ESB acquisition and the addition of support and producing staff in several regions.

Bank-owned life insurance decreased by $0.3 million primarily due to death claims in the first quarter of 2015.

Net gains on sales of mortgage loans increased $0.3 million or 101.5% compared to the first quarter of 2015 due to a larger percentage of originations being sold into the secondary market. Mortgages sold into the secondary market represented $25.2 million or 41.5% of overall mortgage loan production in the first quarter of 2016 compared to $22.9 million or 28.4% in the first quarter of 2015.

Non-interest expense in the first quarter of 2016, excluding merger-related expenses, increased $1.6 million or 3.7%, compared to the first quarter of 2015 due to the ESB acquisition which increased assets by $2.0 billion and added 23 offices to our branch network, and growth in normal operating expenses that have enhanced revenue generation activity throughout the organization. Merger-related expense in the first quarter of 2015 of $9.7 million reflected various costs related to the ESB acquisition, such as employee severance and change-in-control expense, contract termination costs, investment banking, other professional fees and other costs.

Salaries and wages increased $0.8 million or 4.5% from the first quarter of 2015 due to a 3.8% increase in average full-time equivalent employees from the merger, routine annual adjustments to compensation and increased bonus and stock compensation expense. Employee benefits expense decreased $0.2 million or 3.3%, primarily from decreased health insurance costs.

Net occupancy increased $0.1 million in 2016 principally due to increased building-related costs including utilities, lease expense, depreciation and other maintenance costs resulting primarily from the additional ESB offices.

Equipment costs increased $0.5 million related to continuous improvements in computer system infrastructure, and origination and customer support systems, offset somewhat by lower seasonal maintenance expenses.

FDIC insurance expense increased $0.3 million primarily due to the increased size of the balance sheet and adjustments to various risk factors.

Amortization of intangible assets increased $0.2 million from additional ESB intangible assets related to core deposits and non-compete agreements.

Other real estate owned and foreclosure expenses increased $0.2 million in 2016 compared to the first quarter of 2015 due to normal foreclosure and liquidation activity. Other real estate owned and repossessed assets decreased $0.9 million from the first quarter of 2015 to $5.3 million as of March 31, 2016.

Other non-interest expense decreased $0.2 million or 8.8% from the first quarter of 2015 primarily due to the elimination of certain duplicative data servicing fees related to the ESB acquisition prior to the April 24, 2015 system conversion.

33

INCOME TAXES

The provision for federal and state income taxes was $8.7 million in 2016 compared to $4.5 million in the first quarter of 2015. The increase in income tax expense was primarily due to a $13.2 million increase in pre-tax income, higher anticipated pre-tax income for 2016 and a $0.5 million benefit in 2015 relating to the completion of an IRS audit which closed the 2011 and 2012 tax years, all of which caused a higher effective tax rate of 27.5% for 2016 compared to 24.6% in the first quarter of 2015.

FINANCIAL CONDITION

Total assets increased 1.2% during the quarter, while deposits and shareholders’ equity increased 1.3% and 2.1%, respectively, compared to December 31, 2015. Total loans increased $70.5 million or 1.4% as a result of originations outpacing pay downs, due to increased business activity, additional commercial and lending personnel in WesBanco’s urban markets, focused marketing efforts and continued improvement in the loan origination process. Deposits increased $76.6 million resulting from a 3.6% increase in demand deposits and a 1.7% increase in savings deposits, which more than offset the 2.8% decrease in money market deposits and the 0.3% decrease in certificates of deposit. The decrease in certificates of deposit is a result of lower rate offerings for single service maturing certificates of deposit and customer preferences for other deposit types, offset somewhat by an increase in CDARs^® deposits. The increase in demand deposits and savings deposits were attributable to marketing, incentives paid to customers, focused retail and business strategies to obtain more account relationships, and customers’ preference for short-term maturities, coupled with initial deposits from 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. Total borrowings decreased 0.6% during the quarter. FHLB borrowings decreased $2.5 million from December 31, 2015, as FHLB borrowings scheduled to mature were paid down utilizing funds provided by lower cost deposits or other available cash flows. Total shareholders’ equity increased by approximately $23.8 million or 2.1%, compared to December 31, 2015, primarily due to net income exceeding dividends for the period by $13.7 million, coupled with a $12.6 million increase in other comprehensive income as a result of a more positive mark-to-market on available-for-sale securities and year-end pension plan re-measurement.

(1) At March 31, 2016 and December 31, 2015, there were no holdings of any one issuer, other than the U.S. government and certain federal or federally-related 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 35%.

Total investment securities, which are a source of liquidity for WesBanco as well as a contributor to interest income, decreased by $36.8 million or 1.5% from December 31, 2015 to March 31, 2016. Through the first quarter of 2016, the available-for-sale portfolio decreased by $28.8 million or 2.0%, while the held-to-maturity portfolio decreased by $8.0 million or 0.8%. The decrease in the overall portfolio was driven by sales of $15.0 million and maturities, calls and paydowns totaling $105.8 million. These were offset somewhat by purchases of $66.9 million and an increase in the market value of the available-for-sale portfolio in the first quarter of $19.3 million. The weighted average yield of the portfolio remained unchanged from December 31, 2015 at 2.90%.

Net unrealized gains (losses) on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of March 31, 2016 and December 31, 2015 were $8.1 million and ($4.2) million, respectively. Unrealized gains increased significantly on available-for-sale securities due to a decrease in market rates from December 31, 2015. With approximately 42% 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 category available-for-sale.

WesBanco’s municipal portfolio comprises 35.1% of the overall securities portfolio as of March 31, 2016 as compared to 34.8% as of December 31, 2015, and it carries different risks that are not as prevalent in other security types contained in the portfolio. The following table presents the allocation of the municipal bond portfolio based on the combined S&P and Moody’s ratings of the individual bonds (at fair value):

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 value of WesBanco’s securities. For additional disclosure relating to fair value measurements, refer to Note 6, “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 commercial real estate (“CRE”) loans and other commercial and industrial (“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 that increase the risk of default and the potential loss in the event of default to understand their impact on the Bank’s earnings and capital.

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

Total loans increased $67.6 million from December 31, 2015 as loan growth was achieved through $452.5 million in loan originations during the quarter, which represents a 23.5% increase over the first quarter of 2015. CRE land and construction and C&I loans provided the most significant growth, respectively increasing 16.2% and 4.2% for the quarter. Loan growth was driven by additional lending personnel, an expanded presence in our larger urban markets, focused marketing efforts and increased business activity with approximately 80% of the loan growth for the quarter achieved in the central and southwest Ohio markets. Residential real estate loans decreased 0.8% due to lower production and a higher percentage of loans sold into the secondary market. All other loan categories experienced less significant fluctuations from December 31, 2015.

Total loan commitments, including loans approved but not closed, increased $25.2 million or 1.6% from December 2015 due primarily to increases in CRE land and construction and home equity lines of credit originations.

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.

The continued global decline in coal, oil and natural gas prices will have both a positive impact on the commercial portfolio by lowering all borrowers’ energy costs but may also result in a reduction in coal, oil and gas activity that will adversely impact certain industries or property types. At March 31, 2016, total exposure to core energy industries such as drilling, extraction, pipeline construction, mining equipment, investment real estate with energy-related tenants and other related support activities approximated $48 million or 0.74% of total loan exposure compared to $73

37

million or 1.10%, at December 31, 2015. The 34.2% decrease in total exposure from December 31, 2015 was primarily due a $22 million borrower that refinanced with another bank in the first quarter. Exposure to ancillary industries such as utility distribution and transportation, engineering services, manufacturers and retailers of other heavy equipment used in core energy industries, approximated an additional $64 million in exposure or 1.2% of total loans at March 31, 2016, compared to $57 million or 1.1% at December 31, 2015. Approximately $31 million or 48.8% of the ancillary exposure is related to the utility distribution industry, which is generally not impacted by fluctuations in energy prices. The largest exposure to any one borrower in either core energy or ancillary industries was $20.8 million to a company that installs gas line service for new residential and commercial buildings. Not all borrowers in these categories will be impacted to the same magnitude by a reduction in energy sector activity and some may not be at all dependent on, or may be able to replace revenue associated with this industry.

NON-PERFORMING ASSETS, IMPAIRED LOANS 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 nonaccrual of $4.5 million and $4.6 million at March 31, 2016 and December 31, 2015, respectively, are included in total nonaccrual loans.

Non-performing loans, which consist of non-accrual loans and TDRs, decreased $1.5 million or 3.4%, from December 31, 2015. Non-accrual loans increased less than $0.5 million from December 31, 2015 primarily due to a $1.0 million increase in residential real estate loans placed on non-accrual, while TDRs decreased $2.0 million due to successful exit strategies and the reclassification of certain loans due to overall improvement in economic conditions in our markets. (Please see the Notes to the Consolidated Financial Statements for additional discussion.)

Other real estate owned and repossessed assets decreased $0.5 million from December 31, 2015 to March 31, 2016, primarily related to a write-down on a $0.7 million CRE property to facilitate its sale that represented the single largest other real estate owned property acquired from ESB.

Loans past due 90 days or more and accruing interest excluding TDRs increased $1.1 million from December 31, 2015. These loans continue to accrue interest because they are both well-secured and in the process of collection. Loans past due 30-89 days increased $0.9 million from December 31, 2015 and represented 0.23% of total loans at March 31, 2016 increasing slightly from 0.22% at December 31, 2015. Increases in past due status were primarily in commercial loan categories as the past due status on retail loans collectively decreased $3.8 million or 28.4% from year end. The continued low levels of delinquency is the result of management’s continued focus on sound initial underwriting, timely collection of loans at their earliest stage of delinquency, stable unemployment and generally improved economic conditions.

ALLOWANCE FOR CREDIT LOSSES

The allowance for credit losses represented 0.83% of total portfolio loans at March 31, 2016, relatively unchanged from 0.82% at December 31, 2015. The allowance increased $0.8 million from December 31, 2015 to March 31, 2016 primarily due to loan growth. If the acquired ESB loans (which were recorded at fair value at the date of acquisition of $701.0 million) were excluded from the ratio, the allowance would approximate 0.96% of the adjusted loan total as compared to 0.97% at December 31, 2015. The resulting ratio provides greater coverage over total loans and is considered by management to be a better comparison of the adequacy of the allowance. Portfolio mix shifts also affect management’s evaluation of the overall allowance.

The allowance for loans individually evaluated was relatively unchanged from December 31, 2015 to March 31, 2016, while the allowance for loans collectively evaluated increased $1.0 million to $41.2 million due to the aforementioned loan growth.

The allowance for loan commitments of $0.6 million at March 31, 2016 was unchanged from December 31, 2015.

The allowance for credit losses by loan category, presented in Note 4 “Loans and the Allowance for Credit Losses” to 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 all segments is impacted by changes in loan balances, as well as changes in historical loss rates adjusted for qualitative factors such as economic conditions. The CRE and C&I segments of the portfolio are also impacted by changes in the risk grading distribution of the portfolio as well as the migration of CRE loans from land and construction to improved property upon the completion of construction.

The loss migration rate by internal risk grade is the primary factor for establishing the allowance for all commercial loans, and the portfolio segment loss history is the primary factor for establishing the allowance for residential real estate, home equity and consumer loans. The categorization of loans as non-performing is not as significant a factor as the loss migration rate by risk grade or the segment loss history, although certain non-performing loans that carry specific reserves are also typically considered classified under the internal risk grading system. Criticized and classified loans were $84.6 million, or 1.65% of total loans at March 31, 2016, which represents a decrease of 9.0% from $93.0 million or 1.91% of total loans at March 31, 2015 and a slight increase from December 31, 2015, as credit quality continued to improve, enabling certain loans to be upgraded that were criticized but not classified throughout the economic downturn.

Table 13 summarizes the allocation of the allowance for credit losses to each category of the loan portfolio. The increase in the allowance for CRE land and construction loans from December 31, 2015 is primarily due to loan growth in the category. The allowance for CRE improved property and C&I loans was relatively unchanged, despite a 4.2% increase in C&I loans from December 31, 2015 as lower historical loss rates offset the increase in loans. The decrease in the allowance for residential real estate, home equity and consumer loans reflects lower historical loss rates in each category due to overall continued improvement in the credit quality of the portfolio.

Total allowance for credit losses	$	43,115		100.0	$	42,323		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 incurred losses in subsequent periods for any category may necessitate future adjustments to the provision for loan losses applicable to the category. Management believes the allowance for credit losses is appropriate to absorb probable losses at March 31, 2016.

Total deposits	$	6,142,892	$	6,066,299	$	76,593			1.3

Deposits, which represent WesBanco’s primary source of funds, are offered in various account forms at various rates through WesBanco’s 141 branches. The FDIC insures deposits up to $250,000 per account.

Total deposits increased by $76.6 million or 1.3% during the first three months of 2016. Interest bearing demand and non-interest bearing deposits increased 6.3% and 1.3%, respectively, while savings deposits increased 1.7% and money market deposits decreased 2.8%. Increases in deposits are primarily attributable to marketing, incentive compensation paid to customers and employees, focused retail and business strategies to obtain more account relationships and customers’ preferences for shorter-term maturities coupled with initial deposits from 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.

Certificates of deposit decreased 0.3% due to the effects of an overall corporate strategy designed to increase and remix retail deposit relationships with a focus on overall products that can be offered at a lower cost to the Bank. The decline is also impacted by lowered offered rates on maturing certificates of deposit and customer preferences for other non-maturity deposit 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 and the Insured Cash Sweep (ICS^®) money market deposit program. CDARS^® balances totaled $284.8 million in total outstanding balances at March 31, 2016, of which $231.5 million represented one-way buys, compared to $243.7 million in total outstanding balances at December 31, 2015, of which $182.7 million represented one-way buys. ICS^® reciprocal balances totaled $95.0 million at March 31, 2016 compared to $147.3 million at December 31, 2015. Certificates of deposit greater than $250,000 were approximately $224.5 million at March 31, 2016 compared to $232.6 million at December 31, 2015. Certificates of deposit of $100,000 or more were approximately $796.5 million at March 31, 2016 compared to $780.1 million at December 31, 2015. Certificates of deposit totaling approximately $960.7 million at March 31, 2016 with a cost of 0.63% 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 on certain certificates of deposit maturities and savings products based on competition, sales strategies, liquidity needs and wholesale borrowing costs, although in the current interest rate environment, CD rate offerings are generally equal or lower for all maturities and types compared to rates paid on existing CDs.

BORROWINGS

Borrowings are a less significant source of funding for WesBanco compared to total deposits. During the first quarter of 2016, WesBanco reduced other short-term borrowings and paid down FHLB borrowings scheduled to mature utilizing funds provided by lower cost deposits or other available cash flows.

Other short-term borrowings, which consist of securities sold under agreements to repurchase at March 31, 2016, but may also include federal funds purchased and other borrowings, were $76.6 million at March 31, 2016 compared to $81.4 million at December 31, 2015. WesBanco has a revolving line of credit, 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 $25.0 million. There were no outstanding balances as of March 31, 2016 or December 31, 2015.

41

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 8, “Commitments and Contingent Liabilities,” of the Consolidated Financial Statements and the “Loans and Credit Risk” section of this MD&A for additional information.

CAPITAL RESOURCES

Shareholders’ equity increased $23.8 million or 2.1% from $1.1 billion at December 31, 2015. The increase resulted primarily from net income during the current three month period of $22.9 million and a $12.6 million increase in other comprehensive income, which were partially offset by the declaration of common shareholder dividends totaling $9.2 million for the three months ended March 31, 2016. WesBanco also increased its quarterly dividend rate to $0.24 per share in February, representing a 4.3% increase over the prior quarterly rate and a cumulative 71% increase over the last twenty one quarters.

WesBanco purchased 117,100 shares during the three month period ended March 31, 2016 under the current share repurchase plans. At March 31, 2016, the remaining shares authorized to be purchased under the current repurchase plans totaled 1,135,160 shares.

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 March 31, 2016, 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 March 31, 2016, under FDIC regulations, WesBanco could receive, without prior regulatory approval, a dividend of approximately $40.4 million from the Bank. WesBanco intends to continue to improve its consolidated and Bank capital ratios primarily from retaining a majority of its increasing earnings.

The following table summarizes risk-based capital amounts and ratios for WesBanco and the Bank for the periods indicated:

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 59.4% at March 31, 2016 and deposit balances funded 71.7% of assets.

The following table lists the sources of liquidity from assets at March 31, 2016 expected within the next year:

(in thousands)
Cash and cash equivalents	$	167,973
Securities with a maturity date within the next year		11,515
Projected payments and prepayments on mortgage-backed securities and collateralized mortgage obligations (1)		232,032
Callable securities		121,854
Loans held for sale		4,942
Accruing loans scheduled to mature		708,228
Normal loan repayments		467,856
Total sources of liquidity expected within the next year	$	1,714,400

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

Deposit flows are another principal factor affecting overall WesBanco liquidity. Deposits totaled $6.1 billion at March 31, 2016. 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 $960.7 million at March 31, 2016, which includes jumbo regular certificates of deposit totaling $344.1 million with a weighted-average cost of 0.65%, and jumbo CDARS^® deposits of $181.0 million with a cost of 0.70%.

WesBanco maintains a line of credit with the FHLB as an additional funding source. Available credit with the FHLB was approximately $1.1 billion at both March 31, 2016 and December 31, 2015. At March 31, 2016, the Bank had unpledged available-for-sale securities with an amortized cost of $370.6 million, a portion of which is an available liquidity source, or such securities could be pledged to secure additional FHLB borrowings. 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.

WesBanco participates in the Federal Reserve Bank’s Borrower-in-Custody Program (“BIC”) whereby WesBanco pledges certain consumer loans as collateral for borrowings. At March 31, 2016, WesBanco had a BIC line of credit totaling $225.5 million, none of which was outstanding. Alternative funding sources may include the utilization of existing overnight lines of credit with third party banks totaling $250.0 million, none of which was outstanding at March 31, 2016, 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 $76.6 million at March 31, 2016 consisted of overnight sweep checking accounts for large commercial customers. There has not been a significant fluctuation in the average deposit balance of the overnight sweep checking accounts during the first three months of 2016. The overnight sweep checking accounts require 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, $40.8 million in cash and investments on hand, and a $25.0 million revolving line of credit with another financial institution, which did not have an outstanding balance at March 31, 2016. WesBanco is in compliance with all 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 March 31, 2016, under FDIC and State of West Virginia regulations, WesBanco could receive, without prior regulatory approval, dividends of approximately $40.4 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 $1.6 billion and $1.5 billion at March 31, 2016 and December 31, 2015, respectively. On a historical basis, only a small portion of these commitments will result in an outflow of funds. Please refer to Note 8, “Commitments and Contingent Liabilities,” of the Consolidated Financial Statements and the “Loans and Credit Risk” section of this MD&A for additional information.

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 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 equity 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 relative 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, comprised of senior management from various functional areas, monitors and manages interest rate risk within Board approved policy limits. Interest rate risk is monitored primarily through the use of an earnings simulation model. The model is 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 bi-monthly and reviewed and documented by the ALCO.

The earnings simulation model projects changes in net interest income resulting from the effect of changes in interest rates. Forecasting changes in net interest income requires management to make certain assumptions regarding loan and security prepayment rates, bond call dates, and adjustments to non-maturing deposit rates, which may not necessarily reflect the manner in which actual yields and costs respond to changes in market interest rates. Assumptions used are based primarily on historical experience and current market rates. Security portfolio maturities and prepayments are assumed to be reinvested in similar instruments and callable bond forecasts are adjusted at varying levels of interest rates. While management believes such assumptions to be reasonable, there can be no assurance that assumed prepayment rates, callable bond forecasts and non-maturing deposit rates will approximate actual future results. Moreover, the net interest income sensitivity chart presented in Table 1, “Net Interest Income Sensitivity,” assumes the 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, the analysis may not consider all actions that management could employ in response to changes in interest rates and various earning asset and costing liability balances.

Management is aware of the significant effect 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 and terms of its various products and services, both in terms of the costs to offer the services as well as outside market influences upon such pricing, by introducing new products and services or reducing the availability of existing products and services, and by controlling overhead expenses.

Interest rate risk policy limits are determined by measuring the anticipated change in net interest income over a twelve month period assuming an immediate and sustained 100, 200 and 300 basis point increase or decrease in market interest rates compared to a stable rate environment or base model. WesBanco’s current policy limits this exposure to a reduction of 5.0%, 12.5% and 25% or less, respectively, of net interest income from the base model over a twelve month period. The table below shows WesBanco’s interest rate sensitivity at March 31, 2016 and December 31, 2015 assuming a 100, 200 and 300 basis point interest rate increase, compared to a base model. Due to the current low interest rate environment, particularly for short-term rates, the 200 and 300 basis point decreasing change is not calculated.

TABLE 1. NET INTEREST INCOME SENSITIVITY

Immediate Change in Interest Rates	Percentage Change in Net Interest Income from Base over One Year		ALCO
(basis points)	March 31, 2016	December 31, 2015	Guidelines
+300	6.3%	6.2%	(25.0%)
+200	5.6%	5.5%	(12.5%)
+100	4.0%	3.6%	(5.0%)
-100	(2.5%)	(2.7%)	(5.0%)

44

As per the table above, the earnings simulation model at March 31, 2016 currently projects that net interest income for the next twelve month period would decrease by 2.5% if interest rates were to fall immediately by 100 basis points, compared to a decrease of 2.7% for the same scenario as of December 31, 2015.

For rising rate scenarios, net interest income would increase by 4.0%, 5.6%, and 6.3% if rates increased by 100, 200 and 300 basis points, respectively, as of March 31, 2016 compared to increases of 3.6%, 5.5% and 6.2% in a 100, 200 and 300 basis point increasing rate environment as of December 31, 2015.

The balance sheet is asset sensitive as of March 31, 2016, similar to December 31, 2015, based upon changes in the mix of various earning assets and costing liabilities, current year loan and transaction deposit account growth, particularly in non-interest bearing accounts, the impact of the first federal funds rate increase since 2006 of 25 basis points in December, an increase in FHLB borrowings versus short-term certificates of deposit and adjustments in modeling assumptions such as deposit beta rates. In the latter half of 2015, certain FHLB short-term borrowings were extended to terms between one and three year maturities, while additional FHLB borrowings were obtained to replace short-term CD runoff. Recent loan growth has also been primarily concentrated in LIBOR and prime-adjustable loans, which typically increase asset sensitivity. Overall asset sensitivity in non-parallel rising rate scenarios may be somewhat neutralized due to slower prepayment speeds and extension risk associated with residential mortgages and mortgage-backed securities, as well as other earning asset and costing liability differences versus currently modeled assumptions. In addition, variable rate commercial loans with rate floors averaging 4.14% approximated $1.0 billion at March 31, 2016, which represent approximately 33% of commercial loans, as compared to $1.0 billion or 34% of commercial loans at December 31, 2015. Approximately 51% or $517.0 million of these loans are currently priced at their floor, as compared to 52% or $526.6 million at December 31, 2015. In a 100 basis point rising rate environment, these rate floor loans may not re-price or may not significantly re-price from their current floor level as compared to non-floor loans. As a result of the December rate increase, more commercial loans with floors are now scheduled to experience a rate increase in a rising rate environment of 100 basis points, assisting asset sensitivity overall.

Given the current low interest rate environment and flatter yield curve affecting the repricing of loans and investments, WesBanco expects that the base case net interest margin in the near term may remain at relatively similar or slightly lower levels. Management currently anticipates that two additional short-term federal funds rate increases may occur later in 2016, in addition to the first one in December, 2015 of 25 basis points each. While many economists and Federal Reserve Board member commentators have suggested another two to four 25 basis points federal funds rate increases are possible in 2016, with an additional two to four increases in 2017, economic activity in the first quarter of 2016 now suggests a lower probability of such number of increases occurring. A delay in implementing further rate increases may have a negative impact on management’s estimates of the future direction and level of the net interest margin.

Maturities and repricing of higher-costing certificates of deposit serve to mitigate compression from lower loan spreads and general loan re-pricing at lower spreads in the current competitive loan environment, along with anticipated loan growth in most loan categories. However, with current CDs costing an average of 0.68%, this factor is not expected to be as significant in the near term as it was in prior periods when maturing CD rates were higher. Many customers have been electing to move maturing CD balances to lower-costing transaction accounts such as MMDAs until rates rise further, which assists in lowering the cost of deposits in the short run, but may result in a portion of these balances moving back to more expensive CDs upon a significant short-term rate increase. Certificates of deposit runoff over the 12 – 18 months has been replaced with FHLB borrowings, which have increased from $432.5 million at March 31, 2015 to $1,039.3 million at March 31, 2016, also reflecting funding obtained post-closing of ESB for the investment portfolio restructuring that occurred in conjunction with the acquisition. Certificates of deposit totaling approximately $960.7 million mature within the next year at an average cost of 0.63%. The increase in FHLB borrowings overall, and lengthening of their associated maturities, primarily in the second half of 2015, has also assisted in the improving asset sensitive position, as approximately $875.0 million of FHLB borrowings have been extended to over one to three year maturities.

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 swaps as necessary to lengthen liabilities, help offset mismatches in various asset maturities, and manage short-term cash needs. CDARS^® and ICS^® deposits also continue to be used to lengthen maturities in certificates of deposit, and for customers seeking higher-yielding instruments and/or to maintain their total deposit levels below FDIC insurance limits.

Current balance sheet strategies to reduce the potential for margin compression in the current low rate and flatter yield curve environment include:

• increasing total loans; primarily commercial and home equity loans that have variable or adjustable rates;

• selling an increasing amount of new residential mortgage loan production into the secondary market:

• investing available short-term liquidity;

• continuing marketing programs to increase consumer and home equity loans, and non-interest bearing or low-cost interest bearing checking accounts;

• re-mixing securities’ prepayment and maturity cash flows into loans as demand warrants, or to a lesser degree into new investments such as short-to-intermediate duration MBS and CMO securities and intermediate term tax-exempt municipal securities;

• extending or renewing FHLB term borrowings as necessary to balance asset/liability mismatches, and/or use derivatives to accomplish a similar purpose, and

• extending a portion of CD maturities through the CDARS^® program.

As an alternative to the immediate rate shock analysis, the ALCO monitors interest rate risk by ramping or increasing interest rates 200 basis points gradually over a twelve month period. WesBanco’s current policy limits this exposure to 5.0% of net interest income from the base model for

45

a twelve month period. Management believes that the ramping analysis reflects a more realistic movement of interest rates, whereas the immediate rate shock reflects a less likely scenario. The simulation model at March 31, 2016 using the 200 basis point increasing rate ramp analysis, projects that net interest income would increase 3.2% over the next twelve months, compared to a 3.0% increase at December 31, 2015. In addition, management creates a “Most Likely” forecast scenario which is periodically updated and reviewed at each ALCO meeting, incorporating current budget or re-forecast assumptions into the model such as estimated loan and deposit growth, asset and liability remixing, competitive market rates for various products and marketing promotions, and other assumptions. Such model helps to predict changes in forecasted outcomes and necessary adjustments to the plan to achieve management’s earnings goals.

WesBanco periodically measures the economic value of equity, which is defined as the market value of tangible equity in various increasing and decreasing rate scenarios. At March 31, 2016, the market value of tangible equity as a percent of base in a 200 basis point rising rate environment indicates an increase of 3.8%, compared to an increase of 1.9% at December 31, 2015. In a 100 basis point falling rate environment, the model indicates a decrease of 9.9%, compared to a decrease of 8.8% as of December 31, 2015. WesBanco’s policy is to limit such change to minus 20% for a 200 basis point change in interest rates, as long as the Tier 1 leverage capital ratio is not forecasted to decrease below 5.0% as a result of the change. Balance sheet changes in loan and securities portfolios, new borrowings, transaction deposits and certificates of deposit, as well as certain other modeling assumptions, resulted in the change in equity market value from year-end.

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 at the reasonable assurance level as discussed below 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—There were no changes in WesBanco’s internal control over financial reporting that occurred during our fiscal quarter ended March 31, 2016 as required to be reported by paragraph (d) of Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, that materially affected, or are reasonably likely to materially affect, WesBanco’s internal control over financial reporting.

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 March 31, 2016, WesBanco had two active one million share stock repurchase plans. The first plan was originally approved by the Board of Directors on March 21, 2007 and the second, which is incremental to the first, was approved October 22, 2015. Each 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.

The following table presents the monthly share purchase activity during the quarter ended March 31, 2016:

Period	Total Number of Shares Purchased		Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans		Maximum Number of Shares that May Yet Be Purchased Under the Plans

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

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, 2015.

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 2015 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. 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 — In March 2016, the Financial Accounting Standards Board (the “FASB”) issued an Accounting Standards Update (“ASU”) (ASU 2016-09) that will require all income tax effects of stock awards to be recognized in the income statement when the awards vest or are settled. It also will allow an employer to repurchase more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-07 that eliminates the requirement to retrospectively apply the equity method in previous periods when an investor initially obtains significant influence over an investee. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2016, and requires prospective adoption. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02 that will require entities to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The principal difference from previous guidance is that the lease assets and lease liabilities arising from operating leases were not previously recognized in the balance sheet. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. WesBanco is currently evaluating the impact of the adoption of this pronouncement on its Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01 that will require entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicability exception. The standard does not change the guidance for classifying and measuring investments in debt securities and loans. Entities will have to record changes in instrument-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In September 2015, the FASB issued ASU 2015-16 which eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The acquirer still must disclose the amounts and reasons for adjustments to the provisional amounts. The acquirer also must disclose, by line item, the amount of the adjustment reflected in the current-period income statement that would have been recognized in previous periods if the adjustment to provisional amounts had been recognized as of the acquisition date. Alternatively, an acquirer may present those amounts separately on the face of the income statement. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2015, including interim periods with those fiscal years. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In May 2015, the FASB issued ASU 2015-07 related to disclosures for investments in certain entities that calculate net asset value (NAV) per share (or its equivalent). This update removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient and modifies certain disclosure requirements. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2015, and requires retrospective adoption. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-05 that provides guidance on when to account for a cloud computing arrangement as a software license. The guidance applies only to internal-use software that a customer obtains access to in a hosting arrangement if both of the following criteria are met: (1) The customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty, (2) it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In February 2015, the FASB issued ASU 2015-02 that revised the consolidation model, requiring reporting entities to reevaluate whether they should consolidate certain legal entities under the revised model. The amendments in this update modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities, and eliminate the presumption that a general partner should consolidate and affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. The pronouncement also provides for a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In May 2014, the FASB issued ASU 2014-09 related to the recognition of revenue from contracts with customers. The new revenue pronouncement creates a single source of revenue guidance for all companies in all industries and is more principles-based than current revenue guidance. The pronouncement provides a five-step model for a company to recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The five steps are, (1) identify the contract with the customer, (2) identify the separate performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the separate performance obligations and (5) recognize revenue when each performance obligation is satisfied. The pronouncement was originally effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016 using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. Early adoption was not permitted. On July 9, 2015, the FASB approved a one-year deferral of the effective date of the update. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. Early adoption is now permitted as of the original effective date for interim and annual reporting periods in fiscal years beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08 which amends the principal versus agent guidance in the revenue standard. WesBanco is currently evaluating the impact of the adoption of this pronouncement on its Consolidated Financial Statements.

Stock options representing shares of 167,750 and 0 for the three months ended March 31, 2016 and 2015, respectively, were not included in the computation of diluted earnings per share, because to do so would have been anti-dilutive. Contingently issuable shares awarded under the total shareholder return plan were not included in the diluted computation for three months ended March 31, 2016, because to do so would have been anti-dilutive.

On February 10, 2015, WesBanco issued 9,178,531 shares to complete its acquisition of ESB. These shares are included in average shares outstanding beginning on that date.

⁽¹⁾  Mortgage-backed and collateralized mortgage securities, which have prepayment provisions, are not assigned to maturity categories due to fluctuations in their prepayment speeds.

⁽²⁾  Equity securities, which have no stated maturity, are not assigned a maturity category.

⁽³⁾  The held-to-maturity portfolio is carried at an amortized cost of $1.0 billion.

Securities with aggregate fair values of $1.1 billion and $1.0 billion at March 31, 2016 and December 31, 2015, 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 $15.0 million and $560.7 million for the three months ended March 31, 2016 and 2015, respectively. Net unrealized gains (losses) on available-for-sale securities included in accumulated other comprehensive income net of tax, as of March 31, 2016 and December 31, 2015 were $8.1 million and ($4.2) million, respectively.

The following table presents the gross realized gains and losses on sales and calls of securities for the three months ended March 31, 2016 and 2015, respectively.

Unrealized losses on debt securities in the tables represent temporary fluctuations resulting from changes in market rates in relation to fixed yields. Unrealized losses in the available-for-sale portfolio are accounted for as an adjustment, net of taxes, to other comprehensive income in shareholders’ equity.

WesBanco does not believe the securities presented above are impaired due to reasons of credit quality, as substantially all debt securities are rated above investment grade and all are paying principal and interest according to their contractual terms. WesBanco does not intend to sell, nor is it more likely than not that it will be required to sell, loss position securities prior to recovery of their cost, and therefore, management believes the unrealized losses detailed above are temporary and no impairment loss relating to these securities has been recognized.

Securities that do not have readily determinable fair values and for which WesBanco does not exercise significant influence are carried at cost. Cost method investments consist primarily of FHLB of Pittsburgh stock totaling $45.4 million and $45.5 million at March 31, 2016 and December 31, 2015, 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.

⁽¹⁾  Commercial loans greater than $1 million that are reported as non-accrual or as a troubled debt restructuring (“TDR”) are individually evaluated for impairment.

WesBanco maintains an internal loan grading system to reflect the credit quality of commercial loans. Commercial loan risk grades are determined based on an evaluation of the relevant characteristics of each loan, assigned at the inception of each loan 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 reliability and sustainability of the primary source of repayment and overall financial strength of the borrower. This includes an analysis of cash flow available to repay debt, profitability, liquidity, leverage, and overall financial trends. Other factors include management, industry or property type risks, an assessment of secondary sources of repayment such as collateral or guarantees, other terms and conditions of the loan that may increase or reduce its risk, and economic conditions and other external factors that may influence repayment capacity and financial condition.

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 net rental income generated by the property to service the debt, the type, quality, industry and mix of tenants, and the terms of leases, but also considers the overall financial capacity of the investors and their experience in owning and managing investment property. The risk grade assigned to owner-occupied commercial real estate and commercial and industrial loans is based primarily on historical and projected earnings, the adequacy of operating cash flow to service all of the business’ debt, and the capital resources, liquidity and leverage of the business, but also considers the industry in which the business operates, the business’ specific competitive advantages or disadvantages, the quality and experience of management, and external influences on the business such as economic conditions. Other factors that are considered for commercial and industrial loans include the type, quality and marketability of non-real estate collateral and whether the structure of the loan increases or reduces its risk. The type, age, condition, location and any environmental risks associated with a property are also considered for all types of commercial real estate. The overall financial condition and repayment capacity of any guarantors is also evaluated to determine the extent to which they mitigate other risks of the loan. The following paragraphs provide descriptions of risk grades that are applicable to commercial real estate and commercial and industrial loans.

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 or compromised loans are currently protected but have weaknesses, which, if not corrected, may be inadequately protected at some future date. These loans represent an unwarranted credit risk and would generally not be extended in the normal course of lending. Specific issues which may warrant this grade include declining financial results, increased reliance on secondary sources of repayment or guarantor support and adverse external influences that may negatively impact the business or property.

Substandard and doubtful loans are equivalent to the classifications used by banking regulators. Substandard loans are inadequately protected by the current repayment capacity and equity of the borrower or collateral pledged, if any. Substandard loans have one or more well-defined weaknesses that jeopardize their repayment or collection in full. These loans may or may not be reported as non-accrual. Doubtful loans have all the weaknesses inherent to a substandard loan with the added characteristic that full repayment is highly questionable or improbable on the basis of currently existing facts, conditions and collateral values. However, recognition of loss may be deferred if there are reasonably specific pending factors that will reduce the risk if they occur.

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 were $16.0 million at March 31, 2016 and $15.8 million at December 31, 2015, of which $2.1 and $3.1 million were accruing, for each period, respectively. The aggregate amount of residential real estate, home equity and consumer loans classified as substandard are not included in the tables above.

Acquired Loans - Loans acquired with deteriorated credit quality at March 31, 2016 and December 31, 2015 were $7.7 million and $9.3 million, respectively, while the non-accretable difference was $8.0 million and $9.1 million, respectively. At March 31, 2016 and December 31, 2015 no allowance for loan losses has been recognized related to the acquired impaired loans, as estimates of future cash flows on these loans have not been negatively impacted.

The following table provides changes in accretable yield for loans acquired with deteriorated credit quality:

As of March 31, 2016, 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 three months. WesBanco had no unfunded commitments to debtors whose loans were classified as impaired as of March 31, 2016 and $0.2 million as of December 31, 2015.

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair Value Measurement

NOTE 6. 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:

Securities available-for-sale: The fair value of securities available-for-sale 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. Certain equity securities that are lightly traded in over-the-counter markets are classified as level 2 in the fair value hierarchy, as quoted market prices may not be available on the fair value measurement date. 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.

We may be required from time to time to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower of cost or market accounting or write-downs of individual assets.

Impaired loans: Impaired loans are carried at the lower of cost or the fair value of the collateral for collateral-dependent loans. Collateral may be in the form of real estate or business assets including equipment, inventory and accounts receivable. The use of independent appraisals, discounted cash flow models and management’s best judgment are significant inputs in arriving at the fair value measure of the underlying collateral and impaired loans are therefore classified within level 3 of the fair value hierarchy.

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.

Loans held for sale: Loans held for sale are carried, in aggregate, at the lower of cost or fair value. 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.

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 March 31, 2016 and December 31, 2015:

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.

Securities held-to-maturity: Fair values for securities held-to-maturity are determined in the same manner as securities available-for-sale which is 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.

Bank-owned life insurance: The carrying value of bank-owned life insurance represents the net cash surrender value of the underlying insurance policies, should these policies be terminated. Management believes that the carrying value 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.

Junior subordinated debt owed to unconsolidated subsidiary trusts: Due to the pooled nature of these instruments, which are not actively traded, estimated fair value is based on recent similar transactions of single-issuer trust preferred securities.

Accrued interest payable: The carrying amount of accrued interest payable approximates its fair value.

Off-balance sheet financial instruments: Off-balance sheet financial instruments consist of commitments to extend credit, including letters of credit. Fair values for commitments to extend credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present credit standing of the counterparties. The estimated fair value of the commitments to extend credit and letters of credit are insignificant and therefore are not presented in the above tables.

Commitments and Contingent Liabilities

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

NOTE 8. 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 $0.6 million as of both March 31, 2016 and December 31, 2015, and is included in other liabilities on the Consolidated Balance Sheets.

Letters of credit are conditional commitments issued by banks to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including normal business activities, bond financing and similar transactions. Letters of credit are considered guarantees. The liability associated with letters of credit was $0.2 million as of both March 31, 2016 and December 31, 2015.

Contingent obligations to purchase loans funded by other entities include affordable housing plan guarantees, credit card guarantees and mortgages sold into the secondary market with recourse. Affordable housing plan guarantees are performance guarantees for various building project loans. The guarantee amortizes as the loan balances decrease. Credit card guarantees are credit card balances not owned by WesBanco, whereby the Bank guarantees the performance of the cardholder. Certain mortgages sold with recourse obligate WesBanco to repurchase mortgages sold if the borrower exceeds certain delinquency metrics within the first year.

The following table presents total commitments to extend credit, guarantees and various letters of credit outstanding:

(unaudited, in thousands)	March 31, 2016		December 31, 2015
Lines of credit	$	1,210,101	$	1,159,769
Loans approved but not closed		213,959		234,599
Overdraft limits		105,774		106,252
Letters of credit		22,743		27,408
Contingent obligations to purchase loans funded by other entities		18,779		18,079

Contingent Liabilities — WesBanco is a party to various legal and administrative proceedings and claims. While any litigation contains an element of uncertainty, management does not believe that a material loss related to such proceedings or claims pending or known to be threatened is reasonably possible.

Business Segments

NOTE 9. 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 $3.6 billion and $3.9 billion at March 31, 2016 and 2015, 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.

NOTE 10. SUBSEQUENT EVENTS

On May 3, 2016, WesBanco and Your Community Bankshares, Inc. (“YCB”), a bank holding company headquartered in New Albany, Indiana with $1.6 billion in assets and 36 branches, jointly announced that a definitive Agreement and Plan of Merger was executed providing for the merger of YCB with and into WesBanco. The transaction currently is valued at approximately $221.0 million. Under the terms of the Agreement and Plan of Merger, which has been approved by the board of directors of both companies, WesBanco will exchange a combination of its common stock and cash for YCB common stock. YCB shareholders will be entitled to receive 0.964 shares of WesBanco common stock and cash in the amount of $7.70 per share for each share of YCB common stock for a total value of approximately $39.05 per share at the date of announcement. The receipt by YCB shareholders of shares of WesBanco common stock in exchange for their shares of YCB common stock is anticipated to qualify as a tax-free exchange. The acquisition is subject to the approvals of the appropriate banking regulatory authorities and the shareholders of YCB. It is expected that the transaction will be completed in the third or fourth quarter of 2016.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2016

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, 2015.

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 2015 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. 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 — In March 2016, the Financial Accounting Standards Board (the “FASB”) issued an Accounting Standards Update (“ASU”) (ASU 2016-09) that will require all income tax effects of stock awards to be recognized in the income statement when the awards vest or are settled. It also will allow an employer to repurchase more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-07 that eliminates the requirement to retrospectively apply the equity method in previous periods when an investor initially obtains significant influence over an investee. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2016, and requires prospective adoption. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02 that will require entities to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The principal difference from previous guidance is that the lease assets and lease liabilities arising from operating leases were not previously recognized in the balance sheet. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. WesBanco is currently evaluating the impact of the adoption of this pronouncement on its Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01 that will require entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicability exception. The standard does not change the guidance for classifying and measuring investments in debt securities and loans. Entities will have to record changes in instrument-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s Consolidated Financial Statements.

In September 2015, the FASB issued ASU 2015-16 which eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The acquirer still must disclose the amounts and reasons for adjustments to the provisional amounts. The acquirer also must disclose, by line item, the amount of the adjustment reflected in the current-period income statement that would have been recognized in previous periods if the adjustment to provisional amounts had been recognized as of the acquisition date. Alternatively, an acquirer may present those amounts separately on the face of the income statement. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2015, including interim periods with those fiscal years. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In May 2015, the FASB issued ASU 2015-07 related to disclosures for investments in certain entities that calculate net asset value (NAV) per share (or its equivalent). This update removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient and modifies certain disclosure requirements. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2015, and requires retrospective adoption. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-05 that provides guidance on when to account for a cloud computing arrangement as a software license. The guidance applies only to internal-use software that a customer obtains access to in a hosting arrangement if both of the following criteria are met: (1) The customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty, (2) it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In February 2015, the FASB issued ASU 2015-02 that revised the consolidation model, requiring reporting entities to reevaluate whether they should consolidate certain legal entities under the revised model. The amendments in this update modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities, and eliminate the presumption that a general partner should consolidate and affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. The pronouncement also provides for a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.

In May 2014, the FASB issued ASU 2014-09 related to the recognition of revenue from contracts with customers. The new revenue pronouncement creates a single source of revenue guidance for all companies in all industries and is more principles-based than current revenue guidance. The pronouncement provides a five-step model for a company to recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The five steps are, (1) identify the contract with the customer, (2) identify the separate performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the separate performance obligations and (5) recognize revenue when each performance obligation is satisfied. The pronouncement was originally effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016 using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. Early adoption was not permitted. On July 9, 2015, the FASB approved a one-year deferral of the effective date of the update. The update is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2017. Early adoption is now permitted as of the original effective date for interim and annual reporting periods in fiscal years beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08 which amends the principal versus agent guidance in the revenue standard. WesBanco is currently evaluating the impact of the adoption of this pronouncement on its Consolidated Financial Statements.
