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, 2012.

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 2012 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 July 2013, the Financial Accounting Standards Board (the “FASB”) issued an accounting pronouncement to improve the reporting for unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The pronouncement is expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The pronouncement is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s consolidated financial statements.

In February 2013, the FASB issued an accounting pronouncement to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendment does not change the current requirements for reporting net income or other comprehensive income in the financial statements. However, the amendment requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to include references to other disclosures. The pronouncement is effective prospectively for interim and annual reporting periods beginning after December 15, 2012. The adoption of this pronouncement did not have a material impact on WesBanco’s consolidated financial statements.

In December 2011, the FASB issued an accounting pronouncement which requires entities to disclose both gross and net information about instruments and transactions eligible for offset in the statement of financial position, including instruments and transactions subject to master netting arrangements. The scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. The objective of this pronouncement is to enhance disclosures required by GAAP by requiring improved information about financial instruments and derivative instruments that are either offset in accordance with existing GAAP or subject to an enforceable master netting arrangement or similar agreement. This information will enable users of an entity’s financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments. In January 2013, the FASB issued an accounting pronouncement to clarify and limit the scope of the aforementioned pronouncement by more specifically defining transactions eligible for offset. The pronouncements should be applied retrospectively effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The adoption of these pronouncements did not have a material impact on WesBanco’s consolidated financial statements.

Securities with aggregate par values of $703.2 million and $710.5 million at September 30, 2013 and December 31, 2012, 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 $9.3 million and $48.1 million for the nine months ended September 30, 2013 and 2012, respectively. Net unrealized (losses) gains on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of September 30, 2013 and December 31, 2012 were ($0.1) million and $13.0 million, respectively. Gross security gains of $0.3 million and $1.4 million on available-for-sale securities were realized for the nine months ended September 30, 2013 and 2012, respectively, while gross security losses of $0.2 million were realized for the nine months ended September 30, 2013 primarily due to the write-down of two equity securities. Additionally, gross security gains of $0.6 million and $0.3 million on held-to-maturity securities were realized for the nine months ended September 30, 2013 and 2012, respectively.

The following tables provide information on unrealized losses on investment securities that have been in an unrealized loss position for less than twelve months and twelve months or more as of September 30, 2013 and December 31, 2012:

Unrealized losses on debt securities in the table 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 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 of investment grade quality 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 Federal Home Loan Bank (“FHLB”) of Pittsburgh and FHLB of Cincinnati stock totaling $12.0 million and $21.3 million at September 30, 2013 and December 31, 2012, 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 descriptions of risk grades apply to commercial real estate and commercial and industrial loans:

Excellent or minimal risk loans are fully secured by liquid or readily marketable collateral and therefore have virtually no risk of loss. Good or desirable risk loans are extended in the normal course of business to creditworthy borrowers that exhibit a history of positive financial results that are at least comparable to the average for their industry or type of real estate. These loans are expected to perform satisfactorily during most economic cycles and there are no significant external factors that are expected to adversely affect these borrowers more than others in the same industry. Any minor unfavorable characteristics of these loans are outweighed or mitigated by strong positive factors including but not limited to adequate secondary sources of repayment or guarantees.

Fair or acceptable risk loans have a somewhat higher credit risk profile due to specific weaknesses or uncertainties that could adversely impact repayment capacity. Loans in this category generally warrant additional attention or monitoring, or a more rigid loan structure. These loans represent the maximum level of risk accepted in the normal course of lending. Specific issues that may warrant this grade include financial results that are less favorable than the average for the borrower’s industry or type of real estate, cyclical financial results, loans based on projections that have a reasonable probability of being achieved, start-up businesses, construction projects, and other external factors that indicate a higher level of credit risk. Loans that are underwritten primarily on the basis of the repayment capacity or financial condition of guarantors may also be assigned this grade.

11

Criticized or marginal loans are currently protected but have weaknesses, which, if not corrected, may inadequately protect WesBanco Bank, Inc. (the “Bank”) 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 $14.6 million at September 30, 2013 and $17.9 million at December 31, 2012, of which $2.2 and $4.9 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.

Impaired Loans — A loan is considered impaired, based on current information and events, if it is probable that WesBanco will be unable to collect the payments of principal and interest when due according to the contractual terms of the loan agreement. Impaired loans generally included all non-accrual loans and TDRs.

Loans are generally placed on non-accrual status when they become past due 90 days or more unless they are both well-secured and in the process of collection. Loans may also be placed on non-accrual when full collection of principal is in doubt even if payments on such loans remain current, or may remain on non-accrual if they are 90 days or more past due but subsequently brought current and maintained current for at least six consecutive months.

Loans are categorized as TDRs when the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider.

TDRs decreased from December 31, 2012 primarily due to principal reductions and loan sales. The increase in the number of TDR modifications and the number of defaults over the prior year resulted from the implementation of a regulatory requirement in December 2012, to include as TDRs mortgage, home equity and consumer loans discharged in bankruptcy.

As of September 30, 2013, there was one TDR greater than $1.0 million, which was non-accrual, representing $1.5 million or 5.3% of total TDRs, with specific reserves of $0.8 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.

The following tables present details related to loans identified as TDRs during the three and nine months ended September 30, 2013 and 2012, respectively:

NOTE 5. FEDERAL HOME LOAN BANK BORROWINGS

WesBanco is a member of the FHLB System. WesBanco’s FHLB borrowings, which consist of borrowings from both the FHLB of Pittsburgh and the FHLB of Cincinnati, are secured by a blanket lien by the FHLB on certain residential mortgages and other loan types or securities with a market value in excess of the outstanding balances of the borrowings. At September 30, 2013 and December 31, 2012, WesBanco had FHLB borrowings of $59.9 million and $111.2 million, with a weighted-average interest rate of 2.72% and 3.04%, respectively. The decline in borrowings from December 31, 2012 was due to scheduled maturities. The terms of the security agreement with the FHLB include a specific assignment of collateral that requires the maintenance of qualifying mortgage and other types of loans as pledged collateral with unpaid principal amounts in excess of the FHLB advances, when discounted at certain pre-established percentages of the loans’ unpaid principal balances. FHLB stock owned by WesBanco totaling $12.0 million at September 30, 2013 and $21.3 million at December 31, 2012 is also pledged as collateral on these advances. The remaining maximum borrowing capacity by WesBanco with the FHLB at September 30, 2013 and December 31, 2012 was estimated to be approximately $1.5 billion and $1.3 billion, respectively.

Certain FHLB advances contain call features, which allow the FHLB to call the outstanding balance or convert a fixed rate borrowing to a variable rate advance if the strike rate goes beyond a certain predetermined rate. The probability that these advances will be called depends primarily on the level of related interest rates during the call period. Of the $59.9 million outstanding at September 30, 2013, $6.0 million in FHLB convertible advances are subject to call or conversion to a variable rate advance by the FHLB.

The following table presents the aggregate annual maturities and weighted-average interest rates of FHLB borrowings at September 30, 2013 based on their contractual maturity dates and effective interest rates:

The Plan covers all employees of WesBanco and its subsidiaries who were hired on or before August 1, 2007 who satisfy minimum age and length of service requirements, and is not available to employees hired after such date.

A minimum required contribution of $3.7 million is due for 2013 which will be partially funded by the Plan’s $23.6 million available credit balance. A contribution of $2.5 million was made in July 2013 and an additional $2.5 million is expected to be funded in December 2013.

NOTE 7. FAIR VALUE MEASUREMENT

Fair value estimates are based on quoted market prices, if available, quoted market prices of similar assets or liabilities, or the present value of expected future cash flows and other valuation techniques. These valuations are significantly affected by discount rates, cash flow assumptions, and risk assumptions used. Therefore, fair value estimates may not be substantiated by comparison to independent markets and are not intended to reflect the proceeds that may be realizable in an immediate settlement of the instruments.

Fair value is determined at one point in time and is not representative of future value. These amounts do not reflect the total value of a going concern organization. Management does not have the intention to dispose of a significant portion of its assets and liabilities and therefore, the unrealized gains or losses should not be interpreted as a forecast of future earnings and cash flows.

The following is a discussion of assets and liabilities measured at fair value on a recurring basis and valuation techniques applied:

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.

Mortgage servicing rights: The fair value of mortgage servicing rights is based on an independent valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions based on management’s best judgment that are significant inputs to the discounting calculations. If the carrying value exceeds fair value, they are considered impaired and are classified within level 3 of the fair value hierarchy as a result.

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 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, and the credit risk associated with the loan and market factors, including liquidity. The valuation of the loan portfolio reflects discounts that WesBanco believes are consistent with transactions occurring in the marketplace for both performing and distressed loan types. The carrying value that fair value is compared to 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 the rates currently offered for deposits of similar remaining maturities.

21

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 broker prices from recent similar sales.

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 9. 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 $0.4 million and $0.3 million as of September 30, 2013 and December 31, 2012, respectively, and is included in other liabilities on the Consolidated Balance Sheets.

Letters of credit are conditional commitments issued by banks to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including normal business activities, bond financing and similar transactions. Letters of credit are considered guarantees. The liability associated with letters of credit was immaterial as of both September 30, 2013 and December 31, 2012.

Contingent obligations to purchase loans funded by other entities include affordable housing plan guarantees and credit card guarantees. Affordable housing plan guarantees are performance guarantees for various building project loans. The guarantee amortizes as the loan balances decrease. Credit card guarantees are credit card balances not owned by WesBanco, whereby the Bank guarantees the performance of the cardholder.

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

(unaudited, in thousands)	September 30, 2013		December 31, 2012
Lines of credit	$	913,457	$	769,525
Loans approved but not closed		201,838		218,531
Overdraft limits		88,025		93,654
Letters of credit		18,922		20,078
Contingent obligations to purchase loans funded by other entities		6,332		6,668

Contingent Liabilities — WesBanco is a party to various legal and administrative proceedings and claims. While any litigation contains an element of uncertainty, management believes that the outcome of such proceedings or claims pending or known to be threatened will not have a material adverse effect on WesBanco’s consolidated financial position, results of operations or cash flows.

NOTE 10. 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 $3.5 billion and $3.2 billion at September 30, 2013 and 2012, 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.

This discussion and analysis should be read in conjunction with the Consolidated Financial Statements and Notes thereto.

FORWARD-LOOKING STATEMENTS

Forward-looking statements in this report relating to WesBanco’s plans, strategies, objectives, expectations, intentions and adequacy of resources, are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Such statements are subject to important factors that could cause actual results to differ materially from those contemplated by such statements, including, without limitation, that the businesses of WesBanco and Fidelity may not be integrated successfully or such integration may take longer to accomplish than expected; the expected cost savings and any revenue synergies from the merger of WesBanco and Fidelity may not be fully realized within the expected timeframes; disruption from the merger of WesBanco and Fidelity may make it more difficult to maintain relationships with clients, associates, or suppliers; the effects of changing regional and national economic conditions; changes in interest rates, spreads on earning assets and interest-bearing liabilities, and associated interest rate sensitivity; sources of liquidity available to WesBanco and its related subsidiary operations; potential future credit losses and the credit risk of commercial, real estate, and consumer loan customers and their borrowing activities; actions of the Federal Reserve Board, the Federal Deposit Insurance Corporation, the SEC, the Financial Institution Regulatory Authority, the Municipal Securities Rulemaking Board, the Securities Investors Protection Corporation, and other regulatory bodies; potential legislative and federal and state regulatory actions and reform, including, without limitation, the impact of the implementation of the Dodd-Frank Act; adverse decisions of federal and state courts; fraud, scams and schemes of third parties; internet hacking; competitive conditions in the financial services industry; rapidly changing technology affecting financial services; marketability of debt instruments and corresponding impact on fair value adjustments; and/or other external developments materially impacting WesBanco’s operational and financial performance. WesBanco does not assume any duty to update forward-looking statements.

OVERVIEW

WesBanco is a multi-state bank holding company operating through 118 branches, one loan production office and 104 ATM machines in West Virginia, Ohio and western Pennsylvania, offering retail banking, corporate banking, personal and corporate trust services, brokerage services, mortgage banking and insurance. WesBanco’s businesses are significantly impacted by economic factors such as market interest rates, federal monetary and regulatory policies, local and regional economic conditions and the competitive environment’s effect upon WesBanco’s business volumes. WesBanco’s deposit levels are affected by numerous factors including personal savings rates, personal income, and competitive rates on alternative investments, as well as competition from other financial institutions within the markets we serve and liquidity needs of WesBanco. Loan levels are also subject to various factors including construction demand, business financing needs, consumer spending and interest rates, as well as loan terms offered by competing lenders.

On November 30, 2012, WesBanco completed its acquisition of Fidelity Bancorp, Inc. (“Fidelity”), headquartered in Pittsburgh, Pennsylvania. The acquisition was valued at $70.0 million and added 13 branches in the Pittsburgh area to the Bank’s branch network as part of the western Pennsylvania region. WesBanco issued 2,538,460 shares of its common stock and paid $15.4 million in cash in exchange for Fidelity common stock. The acquisition was accounted for as a tax-free exchange for tax purposes.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

WesBanco’s critical accounting policies involving the significant judgments and assumptions used in the preparation of the Consolidated Financial Statements as of September 30, 2013 have remained unchanged from the disclosures presented in WesBanco’s Annual Report on Form 10-K for the year ended December 31, 2012 under the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

RESULTS OF OPERATIONS

EARNINGS SUMMARY

Diluted earnings per share for the nine month period ended September 30, 2013 were up 20.3% to $1.66 compared to $1.38 for the same period last year, while net income for the 2013 nine month period was $48.6 million compared to $36.9 million for 2012, representing an increase of 31.7%. For the third quarter of 2013, diluted earnings per share totaled $0.53 compared to $0.48 for the third quarter of last year, representing an increase of 10.4%, while net income for the 2013 third quarter totaled $15.5 million compared to $12.9 million for 2012, representing an increase of 20.4%. The increased net income improved the return on average assets to 1.07% from 0.89% in the first nine months of last year. The 2013 results include the effect of the late 2012 acquisition of Fidelity.

Net interest income increased $4.4 million or 10.6% in the third quarter of 2013 compared to the same quarter for 2012, due to a 9.8% increase in average earning assets, primarily through increased average loan balances, both organic and from the Fidelity acquisition. Year-to-date, net interest income increased $13.2 million or 10.5% from last year. In addition, the net interest margin increased slightly to 3.52% in the third quarter of 2013, from 3.51% last year. Year-to-date the margin was 3.58% compared to 3.53% in 2012. The year-to-date margin improvement was due to lower funding costs resulting from a 37.4% average reduction in higher rate FHLB advances and other borrowings, primarily through maturities, a 12.7% increase in total average deposits, with 85.4% of the increase from lower cost demand, money market or savings accounts and the repricing at lower rates of maturing CDs. Accretion of the purchase accounting adjustments for loans, CDs and borrowings acquired with the Fidelity merger also improved the net interest margin by 10 basis points year-to-date.

Credit quality has continued to improve over the past year. Total non-performing loans at September 30, 2013 were $53.6 million or 1.40% of total loans, which represents a 9.3% decrease from $59.1 million or 1.76% at September 30, 2012. Criticized and classified loans decreased 28.4% over the last twelve months to $141.3 million, or 3.68% of total loans at September 30, 2013 from $197.4 million and 5.89% last year. The decreases in non-performing loans and criticized and classified loans included the effect of a third quarter 2013 sale of classified loans with a carrying value of $9.4 million, of which $7.3 million were non-performing.

Net charge-offs for the third quarter of 2013 were $5.8 million, or 0.60% of average portfolio loans, and $11.3 million or 0.30% for the year-to-date period, compared to net charge-offs of $4.6 million or 0.54% for the third quarter of 2012, and $18.0 million or 0.55% for the first nine months of 2012. The third quarter of 2013 includes charges-offs related to the loan sale of $3.5 million which were mostly covered by existing reserves.

As a result of an improvement in all measures of credit quality, the provision for credit losses was $2.8 million for the third quarter of 2013, compared to $4.5 million for the same quarter in 2012, and $5.9 million year-to-date compared to $16.6 million last year. The third quarter provision increased $1.8 million from the second quarter of 2013 due primarily to loan growth, increases in one smaller loan specific reserve and the impact on applicable historical loss rates of charge-offs related to the loan sales in the current quarter. The allowance for loan losses represented 1.23% of total portfolio loans at the end of the third quarter 2013 compared to 1.59% last year.

Non-interest income for the quarter ended September 30, 2013 increased $1.2 million or 7.2% compared to the third quarter of 2012, and year-to-date the increase was $5.2 million or 10.9%. Trust fees increased 10.9% for the quarter and 9.7% year-to-date, as assets under management continued to increase from customer development initiatives and overall market improvements. Total trust assets were up 8.2% year-over-year. Net securities brokerage revenues increased 33.2% and 39.9%, respectively, for the quarter and year-to-date periods also due to the new business initiatives. Service charges on deposits and electronic banking fees also continued to grow in the third quarter. Net gains on sales of mortgage loans increased 16.0% year-to-date but decreased in the third quarter due to mortgages being retained during the quarter. In the third quarter there were a lower number of applications due to higher interest rates and fewer refinances. Securities gains were lower due to reduced portfolio restructuring compared to prior periods as interest rates increased.

Non-interest expense increased $3.2 million or 8.8% for the third quarter of 2013 compared to the third quarter of 2012, and $11.7 million or 10.8% for the first nine months of 2013, partially due to recurring expenses related to operating 13 additional branches acquired in the Fidelity acquisition. Most of the back-office and other administrative savings targeted to be obtained from the merger were accomplished by the end of the second quarter. Salaries and wages increased 11.7% for the third quarter and year-to-date periods compared to the same periods in 2012, due to routine annual adjustments to compensation, increased incentives and commissions on higher loan originations and brokerage revenue and an increase in full-time equivalent employees (“FTEs”) of 96, primarily from the Fidelity acquisition. Employee benefit expenses increased primarily from increased pension expense and payroll taxes. Marketing costs were higher compared to 2012 due to additional marketing initiatives during 2013. Lower merger-related costs benefited both the quarter and the year-to-date period of 2013.

The provision for federal and state income taxes increased $5.6 million to $15.8 million for the nine months ended September 30, 2013 compared to $10.2 million in the comparable 2012 period. The increase in income tax expense was due to a $17.3 million increase in pre-tax income, which caused a higher effective tax rate of 24.6% compared to 21.7% for 2012.

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 $4.4 million or 10.6% in the third quarter and $13.2 million or 10.5% in the first nine months of 2013 compared to the same periods in 2012 due to increased average earning assets, primarily through increased average loan balances. Average earning assets increased $484.4 million or 9.8% in the third quarter of 2013 and $450.4 million or 9.2% in the year-to-date period due to growth in average portfolio loan balances of $487.0 million or 14.6% in the third quarter and $466.9 million or 14.3% in the year-to-date period. Approximately two-thirds of the loan growth was from the western Pennsylvania region, which includes the loans acquired, and those subsequently originated, relating to the acquired Fidelity market area. The increase in average earning assets was funded primarily by increases in deposits. Total average deposits in the third quarter increased by $568.8 million or 12.8% from the 2012 third quarter with approximately 70% of the increase provided by the western Pennsylvania region. Deposit increases occurred primarily in demand deposit, savings and money market accounts, with increases other than through the acquisition resulting from marketing campaigns, customer incentives, wealth management and business initiatives, as well as initial deposits from Marcellus and Utica shale gas bonus and royalty payments which totaled $72 million in the third quarter and $243 million in the first nine months. In addition, the net interest margin increased 1 basis point in the third quarter to 3.52% and 5 basis points in the first nine months compared to the same periods of 2012. Cost of funds continued to decline due to lower offered rates on maturing certificates of deposit, an increase in balances of lower-cost products and lower balances of FHLB and other borrowings. Accretion of purchase accounting adjustments for loans, CDs and borrowings related to the Fidelity acquisition totaling $0.8 million or 5 basis points in the third quarter of 2013 and $3.7 million or 10 basis points year-to-date, also benefited the margin. The average rate on interest bearing liabilities declined by 31 basis points while the rate on earning assets decreased by 23 basis points in the first nine months of 2013.

Interest income increased $2.0 million or 3.9% in the third quarter and $5.1 million or 3.2% in the first nine months of 2013 compared to the same periods in 2012 due to the higher average earning assets, partially offset by the lower yields. Rates decreased on all significant earning asset categories from reduced rates on new and repriced assets due to lending competition and the lower interest rate environment. Repricing of loans and the necessity of offering lower rates on quality credits caused a decline in loan yields of 39 basis points for the third quarter of 2013 compared to the third quarter of 2012. However, the increase in average loans mitigated the effect of the low interest rate environment, as loans provide the highest rate for investment in new earning assets. In the third quarter of 2013, average loans represented 70.5% of average earning assets, compared to 67.6% in the same quarter of 2012. Securities yields decreased due to the reinvestment of funds from investment maturities, calls and sales, and additional investment purchases at current lower available interest rates. Taxable securities yields decreased 4 basis points in the third quarter of 2013 compared to the third quarter of 2012, while tax-exempt securities yields declined 64 basis points, due to purchases of municipals at lower rates. Because of their relative yield advantage, the average balance of tax-exempt securities increased 21.1% over the third quarter of last year. Average taxable securities decreased due to calls of government agencies and prepayments in mortgage-backed and collateralized mortgage securities, somewhat offset by purchases of lower-premium collateralized mortgage securities. Purchases of collateralized mortgage securities minimizes 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 pledgable securities. At September 30, 2013, held-to-maturity securities represented approximately 39% of total securities with a weighted average life of 6.5 years.

Portfolio loans increased $483.6 million or 14.4% from September 30, 2012, with $319.2 million from the western Pennsylvania region and the remaining $164.4 million from other WesBanco regions, as originations continued to outpace paydowns. Separate from the western Pennsylvania region, WesBanco grew outstanding loans 4.0% from December 31, 2012 as a result of a 40.1% growth in overall loan originations from the prior year. Loan growth was achieved in commercial, commercial real estate, residential real estate and home equity lending.

In the third quarter of 2013, interest expense decreased $2.4 million or 22.7% and, in the first nine months of 2013, decreased $8.1 million or 24.1% compared to the same 2012 periods due to decreases in rates paid and a continued shift in the liability mix towards less expensive sources of funding, while total average interest bearing balances increased 7.8% in the third quarter and 6.8% in the first nine months. The average rate paid on interest bearing liabilities decreased 30 basis points to 0.73% in the 2013 third quarter from 1.03% in the same quarter of 2012. For the first nine months of 2013, the average rate paid decreased 31 basis points to 0.77% from 1.08% in 2012. Rates paid on deposits declined by 19 basis points in the third quarter due to declines in all deposit categories, as a result of management reducing offered interest rates for most products and mark-to-market accretion of the certificates of deposit acquired from Fidelity. Improvements in the deposit funding mix also lowered the cost of funds, with average certificates of deposit decreasing to 32.5% of total average deposits from 34.0% in the third quarter of last year. Average interest bearing

28

deposits increased by $419.0 million from the third quarter of 2012 with approximately 80% due to the acquisition, and non-interest bearing demand deposits increased by $149.9 million with approximately 50% related to the acquisition. Average deposits increased most significantly in demand and savings product categories, even as offered rates on interest bearing accounts were reduced. Total average demand deposits, including interest bearing and non-interest bearing, increased $252.6 million or 16.7% in the 2013 third quarter compared to the third quarter of 2012 with approximately 80% due to the acquisition. Average certificates of deposit increased by only 7.7%, primarily due to the acquisition and higher CDARS^® balances, as WesBanco continued to focus on reducing rate offerings and growing customers with multiple banking relationships, as opposed to single service certificate of deposit customers. Deposit increases were used to pay down higher-cost maturing FHLB borrowings and certain other borrowings, significantly contributing to the reduced cost of funds. Average total FHLB and other borrowings decreased $97.1 million or 30.9%, due to maturities and paydowns, and were 4.9% of average interest bearing liabilities in the third quarter of 2013 compared to 7.7% in the same 2012 quarter.

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 for the nine months ended September 30, 2013 decreased $10.7 million or 64.2% to $5.9 million compared to $16.6 million for the nine months ended September 30, 2012. This decrease is the result of a 37.4% decrease in net charge-offs, a 9.3% decrease in non-performing loans, a 28.4% reduction in classified and criticized loans, relatively low delinquency, and improved economic conditions in WesBanco’s market areas. The third quarter 2013 provision for credit losses decreased to $2.8 million as compared to $4.5 million for the same quarter in 2012 for the above noted reasons. The third quarter provision increased $1.8 million from the second quarter of 2013 due primarily to loan growth, increases in certain loan specific reserves and the impact on applicable historical loss rates of charge-offs related to the loan sales in the current quarter. The allowance for loan losses represented 1.23% of total portfolio loans at September 30, 2013, compared to 1.43% at December 31, 2012 and 1.59% at September 30, 2012.

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. Non-interest income increased $1.2 million or 7.2% in the third quarter and $5.2 million or 10.9% in the first nine months of 2013 compared to the same periods in 2012. Trust fees increased 10.9% in the third quarter and 9.7% in the first nine months of 2013 as assets under management continued to increase over last year, from customer development initiatives and overall market improvements. Net securities brokerage revenues increased 33.2% and 39.9%, respectively, for the quarter and year-to-date periods also due to the new business initiatives. Service charges on deposits and electronic banking fees also continued to grow in the third quarter. Net gains on sales of mortgage loans increased 16.0% year-to-date but decreased in the third quarter due to mortgages being retained during the quarter. Securities gains were lower due to reduced portfolio restructuring compared to prior periods. In addition, 2013 non-interest income included a $1.1 million bank-owned life insurance death benefit in the first quarter.

Trust fees increased $0.5 million or 10.9% compared to the third quarter of 2012, and $1.3 million or 9.7% compared to the first nine months of 2012, due to new business and higher average trust assets from overall market improvements and the implementation of an organization-wide trust and investment development program and a private banking program for high net worth customers which began in 2012. Higher tax preparation fees for the year-to-date period also contributed to the increase. Trust assets at September 30, 2013 increased to $3.5 billion from $3.2 billion at September 30, 2012. Quarter end trust assets include managed assets of $2.8 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 $856.9 million as of September 30, 2013 and $796.0 million at December 31, 2012, and are included in trust managed assets.

Service charges on deposits, which are primarily customer overdraft fees, increased 5.8% in the first nine months of the year compared to the same period in 2012 due to a higher number of demand deposit accounts, which grew 15.7% in the last twelve months. Growth in deposits was achieved primarily from Fidelity, and the Bank’s own marketing initiatives, which included two marketing campaigns in 2013 targeting non-interest bearing checking accounts and debit card usage.

Electronic banking fees, which include debit card interchange fees, improved by $0.7 million or 7.7% compared to the prior year, due to a higher volume of debit card transactions, which have continued to grow due to marketing initiatives and as customers move more towards electronic transactions.

Net securities brokerage revenue increased $0.4 million or 33.2% compared to the third quarter of 2012 and 39.9% compared to the first nine months of 2012 primarily due to increased production resulting from the implementation of an organization-wide cross-selling program, additional market coverage in the Pittsburgh area and overall improved production in other markets, as well as a new retail licensed banker program throughout our markets.

Net gains on sales of mortgage loans increased 16.0% year-to-date but decreased in the third quarter due to mortgages being retained during the quarter. In the third quarter, refinancing applications decreased due to an industry-wide slowdown as mortgage rates rose in the second quarter particularly affecting refinances. Overall mortgage production increased 32.0% from the first nine months of 2012, and 25.2% from the third quarter of 2012. Mortgages sold into the secondary market during the nine months ended September 30, 2013 increased 26.1% compared to the first nine months of 2012, but decreased 26.9% in the third quarter compared to the 2012 third quarter as management retained 75.4% of mortgage production in the third quarter of 2013 compared to 57.8% in the third quarter of 2012.

Net gains/(losses) on other real estate owned and other assets improved $0.4 million year-to-date compared to the same period in 2012 due to improved pricing for liquidated property.

Non-interest expense increased $3.2 million or 8.8% in the third quarter and $11.7 million or 10.8% year-to-date compared to the same periods in 2012, primarily due to expenses related to operating 13 additional branches acquired in the Fidelity acquisition. Expenses were relatively unchanged compared to the second quarter of 2013.

Salaries and wages increased $1.7 million in the third quarter of 2013 and $5.1 million year-to-date over the comparable periods in 2012 due to routine annual adjustments to compensation, increased commissions on higher loan originations and brokerage revenue and an increase in FTEs of 96, primarily to operate the Pittsburgh franchise. Pre-merger, Fidelity had approximately 160 FTEs with approximately 60 FTEs eliminated after data conversion and other projects were completed. Employee benefits expense increased $0.3 million for the quarter and $1.9 million year-to-date primarily due to higher payroll taxes and higher pension expense from changes in certain assumptions. Supplemental employee retirement benefits were down $0.3 million related to the bank-owned life insurance claim.

Net occupancy and equipment increased for both the quarter and year-to-date periods due to increased depreciation and other maintenance costs resulting from the Fidelity acquisition, which added approximately $9.1 million in depreciable assets at fair value. In addition, new teller cash recycling machines were introduced into our branches, which have improved the speed of customer service, improved cash controls and reduced FTEs.

Marketing expenses for the nine month period of $4.0 million increased 22.3% over the comparable prior year period due to the addition of the Pittsburgh metropolitan market. Marketing expenses in 2013 also included multiple marketing campaigns targeting non-interest bearing checking accounts and debit card usage as compared to lower campaign expense in 2012.

FDIC insurance expenses decreased $0.2 million or 5.3% year-to-date due to improving capital, net income and loan quality financial ratios which are used to calculate the assessment rate, even after adding in the deposits and other liabilities of Fidelity.

Amortization of intangible assets increased $0.2 million or 10.3% year-to-date due to the Fidelity acquisition, which added approximately $4.7 million in core deposit intangibles.

Restructuring and merger-related expenses of $1.3 million in 2013 include $0.3 million related to systems conversion, $0.4 million in employee severance, $0.2 million in accounting and valuation expenses and $0.4 million of various other merger-related expenses, as compared to $1.5 million last year.

Other real estate owned and foreclosure expenses increased $0.3 million in the third quarter but remained flat year-to-date from 2012 due to the timing of foreclosure-related expenses and liquidation activity in the current year. Other real estate owned and repossessed assets were $5.2 million at September 30, 2013 down $0.8 million from December 31, 2012.

ATM and interchange expenses, which include debit card processing fees, increased $0.5 million or 17.5% in the first nine months of 2013 compared to the same period in 2012, due to a higher volume of debit card transactions during the period as demand deposit accounts grew 15.7% in the last twelve months, primarily from Fidelity, and the Bank’s own marketing initiatives.

32

Electronic bill pay expenses in 2013 increased $0.3 million or 30.7% compared to the prior year, due to a higher volume of online bill pay transactions, which have continued to grow as customers move more towards electronic transactions.

INCOME TAXES

The provision for federal and state income taxes increased $5.6 million to $15.8 million for the nine months ended September 30, 2013 compared to $10.2 million in the comparable 2012 period. The increase in income tax expense was due to a $17.3 million increase in pre-tax income, which caused a higher effective tax rate of 24.6% compared to 21.7% for 2012.

FINANCIAL CONDITION

Total assets increased 1.0% while shareholders’ equity increased 3.2% compared to December 31, 2012. Net loans increased 4.2% compared to December 31, 2012 as loan originations and resulting outstandings outpaced pay-downs. Deposits increased 2.3% compared to December 31, 2012 primarily due to a 4.8% increase in demand deposits, a 4.8% increase in savings deposits, and a 1.3% increase in money market deposits, which were slightly offset by a 0.7% decrease in CDs. The increases in demand, savings deposits, and money market deposits are primarily a result of marketing campaigns, customer incentives, additional wealth management deposits, and treasury management and other business banking initiatives for commercial customers. Deposits also benefited from customers receiving bonus and royalty payments from natural gas companies operating in the Marcellus and Utica shale formations in southwestern Pennsylvania, eastern Ohio and northern West Virginia. The reduction in CDs was anticipated due to lower offered rates for new and rollover CDs, and customers’ desire to shorten interest rate maturities. FHLB borrowings decreased 46.1% from December 31, 2012 as higher cost maturing FHLB borrowings were liquidated using available funding provided by the increase in lower cost deposits. Total shareholders’ equity increased by approximately $22.5 million or 3.2% compared to December 31, 2012, due to net income exceeding dividends for the period by $31.6 million and a $3.0 million increase in capital stock and surplus resulting primarily from employee benefit plan transactions, which was partially offset by a $13.2 million change in unrealized gains in the available-for-sale securities portfolio recognized in accumulated other comprehensive income due to the rising rate environment.

(1) At September 30, 2013 and December 31, 2012, 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 $87.7 million or 5.4% from December 31, 2012 to September 30, 2013. Through the first nine months of 2013, the available-for-sale portfolio decreased by $87.8 million or 8.6% while the held-to-maturity portfolio remained relatively unchanged. This is particularly due to all recent purchases of municipal bonds being placed into the held-to-maturity category due to the potential impact on shareholders’ equity associated with the current interest rate environment and security maturity length. These purchases of municipal securities have offset paydowns or calls of residential mortgage-backed securities and municipal bonds in the held-to-maturity category. For the nine months ended September 30, 2013, security sales totaled $9.3 million and maturities, paydowns, and calls totaled $267.3 million. These were partially offset by purchases of $214.3 million in the first nine months of 2013.

Net unrealized (losses) gains on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of September 30, 2013 and December 31, 2012 were ($0.1) million and $13.0 million, respectively. Unrealized gains on available-for-sale securities decreased due to a significant increase in market rates from December 31, 2012. With approximately 39% of the total investment portfolio in the held-to-maturity category, the volatility in interest rates that has occurred recently does not have as much impact on other comprehensive income as if the entire portfolio was included in the category available-for-sale.

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 7, “Fair Value Measurement” in the Consolidated Financial Statements.

LOANS AND CREDIT RISK

Loans represent WesBanco’s single largest balance sheet asset classification and the largest source of interest income. Business purpose loans consist of 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, new regulatory restrictions and limitations, 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 $133.5 million or 3.6% from December 31, 2012 to September 30, 2013, as new loan originations outpaced pay-downs and grew 40.1% compared to originations in the first nine months of 2012. CRE land and construction loans increased $24.0 million or 12.5% as new construction loans and advances on existing loans exceeded completed projects transferred to CRE improved property. CRE improved property loans decreased $14.6 million or 0.9% primarily due to repayment of recently completed construction loans that were refinanced in the conduit market upon completion or stabilization of the project. C&I loans increased $66.2 million or 13.8% from December 31, 2012, approximately half of which is attributable to an increase in the usage of existing lines of credit with the remainder attributable to new loan originations. Residential real estate loans increased $86.0 million or 10.8% from December 31, 2012, primarily due to a 34.6% increase in new loan originations during the nine months ended September 30, 2013 over the comparable period in 2012 combined with management’s election to retain for its portfolio approximately 65% of new mortgage originations in both the first nine months of 2013 and 2012, respectively. Management retained 75.4% of mortgage production in the third quarter of 2013; however mortgage applications declined due to higher interest rates and fewer refinances. Home equity lines of credit increased $6.3 million or 2.3% from December 31, 2012, while consumer loans decreased $19.1 million or 6.8% due to reduced loan demand and competitive factors. Loans held for sale decreased $15.3 million due to timing of scheduled closings and due to more mortgages being retained in the portfolio during the quarter. Loan growth has been achieved in 2013 while also maintaining WesBanco’s disciplined underwriting and pricing practices in a highly competitive lending market for high quality borrowers.

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 non-accrual of $12.9 million and $15.0 million at September 30, 2013 and December 31, 2012, respectively, are included in total non-accrual loans.

Non-performing loans which consist of non-accrual loans and TDRs decreased $10.0 million or 15.7% from December 31, 2012 to September 30, 2013. The decrease in non-performing loans includes the effect of a third quarter 2013 sale of classified loans with a carrying value of $9.4 million, of which $7.3 million were non-performing. Most of the decrease was in TDRs accruing interest, which decreased $8.8 million as a result of principal reductions, loan sale proceeds, and the migration of certain commercial real estate TDRs to non-accrual. (Please see the Notes to the Consolidated Financial Statements for additional discussion.)

Other real estate owned and repossessed assets decreased $0.8 million from December 31, 2012 to September 30, 2013, as sales of foreclosed properties exceeded new foreclosures and repossessions.

These loans continue to accrue interest because they are both well-secured and in the process of collection. Loans past due 30-89 days decreased $6.9 million or 30.8% between December 31, 2012 and September 30, 2013 as a result of a continued focus on controlling early stage delinquency and improvement in economic conditions in WesBanco’s market areas, as well as more aggressive collection activities in the Western Pennsylvania market on former Fidelity loans that were past due on the merger date.

ALLOWANCE FOR CREDIT LOSSES

The allowance for loan losses decreased $5.4 million to $47.3 million from December 31, 2012 to September 30, 2013 due to lower delinquency, decreases in net charge-offs, and reduced levels of classified and criticized loans and represented 1.23% of total loans at September 30, 2013, compared to 1.43% at December 31, 2012 and 1.59% at September 30, 2012. However, if the acquired Fidelity loans, which were recorded at fair value at the date of acquisition, were excluded from the ratio, the allowance would approximate 1.30% of the adjusted loan total at September 30, 2013. The overall improvement in credit quality supported the reduction in the allowance and a lower provision expense for the nine months ended September 30, 2013. The third quarter provision increased $1.8 million from the second quarter of 2013 due primarily to loan growth, increases in certain loan specific reserves and, to a lesser extent, the impact on applicable historical loss rates of charge-offs related to the loan sales in the current quarter.

Net charge-offs for the third quarter of 2013 were $5.8 million, or 0.60% of average portfolio loans, and $11.3 million or 0.30% for the year-to-date period, compared to net charge-offs of $4.6 million or 0.54% for the third quarter of 2012, and $18.0 million or 0.55% for the first nine months of 2012. The third quarter of 2013 includes charges-offs related to the loan sale of $3.5 million which were mostly covered by existing reserves.

The allowance for loan commitments from December 31, 2012 to September 30, 2013 was relatively unchanged.

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 reclassification of CRE loans from land and construction to improved property upon the completion of construction.

The internal risk rating is the primary factor for establishing the allowance for all commercial loans, and 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 is the internal risk grade of the loan, although certain non-performing loans carry established specific reserves and are also typically considered classified under the Bank’s risk grading system. Classified and criticized loans decreased $56.1 million or 28.4% from September 30, 2012, from principal reductions, charge-offs, migration of certain loans back to a pass grade as a result of improved risk profiles, and orderly exits of certain loans. Classified and criticized loans decreased $31.4 million or 18.2% from December 31, 2012.

Table 14 summarizes the allocation of the allowance for credit losses to each category of the loan portfolio. The allowance for CRE land and construction loans increased primarily due to the 12.5% increase in CRE land and construction loans from December 31, 2012. The allowance for CRE improved property loans, which represents the largest percent of the total allowance, decreased primarily due to the sale of one non-performing loan which eliminated a $2.1 million specific reserve. The allowance for C&I loans decreased as a result of a 76% reduction in net C&I charge-offs between 2012 and 2013, which more than offset the impact of growth in C&I loans. The allowance for residential real estate and home equity loans decreased due primarily to improving credit quality while the allowance for consumer loans decreased primarily due to the decrease in consumer loans.

Although the allowance for credit losses is allocated as described in Table 14, 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 September 30, 2013.

Total deposits	$	5,060,442	$	4,944,284	$	116,158			2.3

Deposits, which represent WesBanco’s primary source of funds, are offered in various account forms at various rates through WesBanco’s 118 branches. Total deposits increased by $116.2 million or 2.3% during the nine months ended September 30, 2013.

Demand deposits and savings deposits increased by 4.8%, while money market deposits increased by 1.3%, due to marketing, incentive compensation paid to customers, focused retail and business strategies to obtain more account relationships and customers’ preferences for shorter-term maturities.

The 0.7% decline in certificates of deposit is 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, which had $364.5 million in total outstanding balances at September 30, 2013 compared to $263.9 million in total outstanding balances at December 31, 2012. Certificates of deposit greater than $250,000 were approximately $183.4 million at September 30, 2013 compared to $189.9 million at December 31, 2012. Certificates of deposit of $100,000 or more were approximately $893.8 million at September 30, 2013 compared to $827.6 million at December 31, 2012. Certificates of deposit totaling approximately $908.9 million at September 30, 2013 with a cost of 1.35% are scheduled to mature within the next 12 months, of which $290 million will mature in the fourth quarter, excluding CDARS^®, at a cost of 2.33%. WesBanco will 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 average rates paid on existing CDs.

BORROWINGS

Total	$	290,224	$	367,990	$	(77,766	)		(21.1	)

During the first nine months of 2013, WesBanco paid down FHLB borrowings scheduled to mature, utilizing funds provided by lower cost deposits or other available cash flows for their payoff. Additional maturities of $20.1 million are scheduled for the last quarter of the year which may result in a further lowering of the cost of wholesale borrowings as these borrowings may be paid off with available funds or renewed at lower market rates. WesBanco also redeemed a $7.5 million former Fidelity trust preferred security with available cash in March at a redemption price of 100% of the principal plus accrued and unpaid interest.

Other short-term borrowings, which consist of securities sold under agreements to repurchase and federal funds purchased, were $124.2 million at September 30, 2013 compared to $143.0 million at December 31, 2012. The decrease in these borrowings has occurred as a result of an $18.8 million decrease in securities sold under agreements to repurchase.

A revolving line of credit with another bank is available to WesBanco. The revolving line of credit, which accrues interest at an adjusted LIBOR rate, provides for aggregate borrowings secured by a pledge of the Bank’s common stock of up to $25.0 million. There were no outstanding balances as of September 30, 2013 or December 31, 2012. The line was renewed for one year in July 2013 at similar terms to the existing note.

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 9, “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 was $736.7 million at September 30, 2013 compared to $714.2 million at December 31, 2012. Total equity increased due to net income during the current nine month period of $48.6 million. The increase was partially offset by a $12.1 million decrease in other comprehensive income and the declaration of common shareholder dividends totaling $17.0 million for the nine months ended September 30, 2013. WesBanco increased its quarterly dividend rate to $0.20 per share in August, representing a 5.3% increase over the prior quarter rate and a cumulative 43% increase over the last eleven quarters. Dividends represented 35.0% of net earnings for the nine months ended September 30, 2013.

Regulatory guidelines require bank holding companies and commercial banks to maintain certain minimum capital ratios and define companies as “well capitalized” that sufficiently exceed the minimum ratios. At September 30, 2013, 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 as well as the recently finalized Basel III capital standards. There are various legal limitations under federal and state laws that limit the payment of dividends from the Bank to WesBanco. As of September 30, 2013, under FDIC regulations, WesBanco could receive, without prior regulatory approval, a dividend of approximately $40.4 million from the Bank. WesBanco will continue to improve its consolidated and Bank capital ratios primarily from retaining a majority of its increasing earnings.

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

In July 2013, the Board of Governors of the Federal Reserve System adopted a final rule that revises risk-based and leverage capital requirements. The final rule consolidates the Notices of Proposed Rulemaking announced in June 2012, with selected changes, resulting in higher risk-based and leverage capital requirements consistent with the Basel Committee on Banking Supervision capital rules. The final rule is effective January 1, 2015 for smaller, non-complex banking organizations with full Basel III implementation by January 1, 2019.

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 loan to asset ratio was 61.7% at September 30, 2013 and deposit balances funded 82.4% of assets.

The following table lists the sources of liquidity from assets at September 30, 2013 expected within the next year:

(unaudited, in thousands)
Cash and cash equivalents	$	145,639
Securities with a maturity date within the next year		17,372
Projected payments and prepayments on mortgage-backed securities and collateralized mortgage obligations (1)		209,693
Callable securities		111,578
Loans held for sale		6,601
Accruing loans scheduled to mature		619,207
Normal loan repayments		321,800
Total sources of liquidity expected within the next year	$	1,431,890

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

Deposit flows are another principal factor affecting overall WesBanco liquidity. Deposits totaled $5.1 billion at September 30, 2013. 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 $908.9 million at September 30, 2013, which includes jumbo regular certificates of deposit totaling $304.6 million with a weighted-average cost of 2.27%, and jumbo CDARS^® deposits of $184.4 million with a cost of 0.42%.

WesBanco maintains a line of credit with the FHLB as an additional funding source. Available credit with the FHLB at September 30, 2013 approximated $1.5 billion, compared to $1.3 billion at December 31, 2012. At September 30, 2013, the Bank had unpledged available-for-sale securities with an amortized cost of $304.1 million, a portion of which is an available liquidity source, or 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 borrowings 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 September 30, 2013, WesBanco had a BIC line of credit totaling $143.0 million, none of which was outstanding. Alternative funding sources may include the utilization of existing overnight lines of credit with third party banks totaling $145.0 million, none of which was outstanding at September 30, 2013, 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 $124.2 million at September 30, 2013 consisted of federal funds purchased, callable repurchase agreements and 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 2013. The repurchase agreements require securities to be pledged equal to or greater than the instrument’s purchase price and may be called at any time by the purchaser, although due to current low interest rates, that is unlikely. 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, $28.3 million in cash and investments on hand, and a $25 million revolving line of credit with another bank, which did not have an outstanding balance at September 30, 2013. 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 September 30, 2013, 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 WesBanco given the current environment. Two metrics that are used to gauge the adequacy of the parent company’s cash position are the Cash Flow Match (“CFM”) and Time to Required Funding (“TRF”). The CFM is defined as year-to-date cash inflows divided by year-to-date cash outflows. The CFM was 1.7 times at September 30, 2013. The internal limit for CFM is for the ratio to be greater than or equal to 1.1 times. The TRF is defined as the number of months of corporate expenses that can be covered by the cash on hand without accessing additional sources of funding and assuming that subsidiary and shareholder dividends are suspended. The TRF was 33 months at September 30, 2013. The internal limit for TRF is for the ratio to be greater than or equal to 12 months.

42

At September 30, 2013, WesBanco had outstanding commitments to extend credit in the ordinary course of business approximating $1.2 billion, compared to $1.1 billion at December 31, 2012. On a historical basis, only a small portion of these commitments will result in an outflow of funds. Please refer to Note 9, “Commitments and Contingent Liabilities,” of the Consolidated Financial Statements and the “Loans and Credit Risk” section of this MD&A for additional information.

Federal financial regulatory agencies have issued guidance to provide for sound practices for managing funding and liquidity risk and strengthening liquidity risk management practices. The guidance recommends that financial institutions maintain a comprehensive management process for identifying, measuring, monitoring, and controlling liquidity risk and that liquidity risk management be fully integrated into its risk management process. WesBanco completed the implementation of these policies, and management believes WesBanco has sufficient current liquidity to meet current obligations to borrowers, depositors and others as of September 30, 2013 and that WesBanco’s current liquidity risk management policies and procedures adequately address this guidance.

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 September 30, 2013 and December 31, 2012 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)	September 30, 2013	December 31, 2012	Guidelines
+300	(1.1%)	0.4%	(25.0%)
+200	0.6%	0.9%	(12.5%)
+100	1.0%	0.9%	(5.0%)
-100	(2.0%)	(4.1%)	(5.0%)

44

As per the table above, the earnings simulation model at September 30, 2013 currently projects that net interest income for the next twelve month period would decrease by 2.0% if interest rates were to fall immediately by 100 basis points, compared to a decrease of 4.1% for the same scenario as of December 31, 2012.

For rising rate scenarios, net interest income would increase by 1.0%, 0.6%, and decrease by 1.1% if rates increased by 100, 200 and 300 basis points, respectively, as of September 30, 2013 compared to increases of 0.9%, 0.9% and 0.4% in a 100, 200 and 300 basis point increasing rate environment as of December 31, 2012.

The balance sheet is slightly less asset sensitive as of September 30, 2013 compared to December 31, 2012 due primarily to continued changes in the mix of various earning assets and costing liabilities, particularly loan growth, transaction deposit account growth and borrowings reduction, as well as certain changes in modeling assumptions. The restructuring of certain acquired earning assets and costing liabilities from Fidelity had a positive impact upon net interest income compared to Fidelity’s combined assets and liabilities at acquisition which were more liability sensitive. Should rates rise more rapidly and by a higher amount, which is not currently anticipated in the short to intermediate term, overall asset sensitivity may be somewhat neutralized due to slower anticipated prepayment speeds and extension risk associated with residential mortgages and mortgage-backed securities. In addition, variable rate commercial loans with rate floors approximated $1.0 billion at September 30, 2013, which represented approximately 44% of commercial loans, with an average floor of 4.42%. In a 100 basis point rising rate environment, these loans would not significantly reprice from their current floor level. However, not all such loans are currently priced at their floor. In the current steeper yield curve environment, WesBanco expects that the net interest margin will be relatively flat through the remainder of 2013 and into 2014, and slightly higher if rates were to rise, although short term interest rates are not currently anticipated to increase until sometime in 2015, and assets and liabilities reprice. It is also anticipated that accretion from loans acquired from Fidelity, as well as mark-to-market accretion from CDs and short-term borrowings, will have a reduced impact on net interest income thru the rest of 2013. However, offsetting those negative factors are maturities of higher-cost borrowings and certificates of deposit scheduled over the next year, which should mostly mitigate margin compression from loan yield decreases and investment security reinvestments. Of note, the Bank continues to experience significant pricing competition for new loans, particularly for new commercial real estate and construction loans, which may result in reduced loan yields that may be somewhat mitigated by future loan growth. Certificates of deposit totaling approximately $908.9 million mature within the next year at an average cost of 1.35%, and approximately $290 million of higher-costing CDs, excluding CDARS^®, will mature during the final three months of 2013 at an average cost of 2.33%.

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 as necessary to mitigate the impact on our balance sheet of embedded options in commercial and residential loans and to lengthen liabilities to help offset mismatches in various asset maturities, as well as to manage short term cash needs. CDARS^® deposits also continue to be used to lengthen maturities in certificates of deposit, and for customers seeking to maintain balances below insured limits.

Current balance sheet strategies to reduce the impact of margin compression in a low rate environment, where asset yields continue to fall as reinvestment of cash flows occur and liability costs may not be able to be reduced in the same proportion, include:

• increasing total loans; primarily commercial and residential with fixed rate periods of between 3-15 years or variable to a published index;

• investing non-essential available short-term liquidity;

• marketing programs to increase consumer loan types and certain types of transaction accounts versus short-term certificates of deposit;

• reinvestment of securities cash flows into a mix of short-to intermediate-term collateralized mortgage obligations and 10-15 year state and municipal securities;

• paying down maturities of FHLB and other short-term borrowings with available cash, or borrowing at lower rates; and

• extending a portion of CD maturities through the CDARS^® program and continuing to decrease offered rates on CDs and other costing deposit types.

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 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 September 30, 2013, using the 200 basis point increasing rate ramp analysis, projects that net interest income would increase 0.9% over the next twelve months, compared to a 1.2% increase at December 31, 2012.

WesBanco also 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 September 30, 2013, the market value of tangible equity as a percent of base in a 200 basis point rising rate environment indicates a decrease of 2.9%, compared to an increase of 15.4% at December 31, 2012. In a 100 basis point falling rate environment, the model indicates a decrease of 6.2%, compared to an increase of 5.2% as of December 31, 2012. 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, continued maturities of borrowings and certificates of deposit, and adding certain transaction-type deposits, change in interest rates since year end, as well as certain other modeling assumptions, have 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 September 30, 2013 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

Litigation Related to the Fidelity Merger

On October 18, 2012, Mordechai Nagel, a purported shareholder of Fidelity, filed a purported shareholder class and derivative action in the Court of Common Pleas of Allegheny County, Pennsylvania, Civil Action No. 12-019908 (the “Allegheny County Lawsuit”). The lawsuit names as Defendants each of the former members of Fidelity’s board of directors (the “Director Defendants”), as well as WesBanco and Fidelity (collectively with the Director Defendants, the “Defendants”). The complaint alleges, among other things, that the Director Defendants breached their fiduciary duties as a result of the price and certain other terms of the Fidelity Merger. The lawsuit also claims that the Director Defendants breached their fiduciary duties because the registration statement on Form S-4 filed by WesBanco with the SEC on September 14, 2012 allegedly contained misstatements and omitted information material to the Fidelity Merger and to a decision by Fidelity’s shareholders regarding whether or not to approve the Fidelity Merger. The lawsuit also alleges that WesBanco aided and abetted the Director Defendants’ alleged breaches of fiduciary duties. The lawsuit sought, among other things, an injunction against WesBanco’s acquisition of Fidelity, as well as the payment of the fees and expenses of the plaintiffs’ attorneys.

On November 16, 2012, solely to avoid the costs, risks and uncertainties inherent in litigation and to allow Fidelity shareholders to vote on the proposals required in connection with the Fidelity Merger at the scheduled meeting on November 27, 2012, the Defendants entered into a Memorandum of Settlement (“MOS”) with the Plaintiff that describes a settlement of the Allegheny County Lawsuit. The settlement is expressly subject to approval by the court. Pursuant to the terms of the MOS, Fidelity and WesBanco agreed to file with the SEC and make publicly available supplemental disclosures. In return, the Plaintiff agreed to stay the Allegheny County Lawsuit, withdraw all requests for interim relief, and not take any action to delay or disrupt the November 27, 2012 Fidelity shareholder meeting. The MOS provides for limited discovery to confirm the fairness of the settlement. If the court approves the settlement contemplated in the MOS, the Allegheny County Lawsuit will be dismissed with prejudice, and all claims that were or could have been brought relating to the Fidelity Merger, the Merger Agreement, and any disclosure made in connection therewith will be released and barred, other than claims under the federal securities laws with respect to any period prior to the date of the Merger Agreement that are not based upon the foregoing. Under the terms of the MOS, counsel for the Plaintiff will petition the court for an award of attorneys’ fees and expenses. The parties have agreed on a fee recommendation to the Court. The amount of the fees and expenses awarded will be determined and approved by the court. In the MOS, the parties have agreed to prepare a stipulation of settlement to be filed with the court and other documentation as may be required to effectuate the settlement and they have now done so. The Court hearing on the fairness of the settlement is scheduled for November 19, 2013. There can be no assurance that the court will approve the settlement. The proposed settlement contemplated by the MOS becomes void in the event that the court does not approve the settlement.

The Defendants have denied and continue to deny that they have committed, or aided and abetted in the commission of, any violation of law or duty or engaged in any wrongful acts and that any supplemental disclosure of the information is required under any applicable state or federal law, statute, rule or regulation. The Defendants also expressly maintain that they diligently and scrupulously complied with all applicable fiduciary, disclosure and all other legal duties. WesBanco does not expect the settlement to be material in relation to its business, financial condition or results of operations.

Other Litigation

WesBanco is also involved in lawsuits, claims, investigations and proceedings which arise in the ordinary course of business. There are none of these matters pending that WesBanco expects to be material in relation to its business, financial condition or results of operations.

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

As of September 30, 2013, WesBanco had a current stock repurchase plan in which up to one million shares can be acquired.

Segment Reporting [Abstract]

Business Segments

NOTE 10. 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 $3.5 billion and $3.2 billion at September 30, 2013 and 2012, 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.

Condensed financial information by business segment is presented below:

At September 30, 2013, and December 31, 2012, there were no holdings of any one issuer, other than the U.S. government and its agencies, in an amount greater than 10% of WesBanco’s shareholders’ equity.

The following table presents the fair value of available-for-sale and held-to-maturity securities by contractual maturity at September 30, 2013. In some instances, the issuers may have the right to call or prepay obligations without penalty prior to the contractual maturity 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 $602.6 million.

Securities with aggregate par values of $703.2 million and $710.5 million at September 30, 2013 and December 31, 2012, 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 $9.3 million and $48.1 million for the nine months ended September 30, 2013 and 2012, respectively. Net unrealized (losses) gains on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of September 30, 2013 and December 31, 2012 were ($0.1) million and $13.0 million, respectively. Gross security gains of $0.3 million and $1.4 million on available-for-sale securities were realized for the nine months ended September 30, 2013 and 2012, respectively, while gross security losses of $0.2 million were realized for the nine months ended September 30, 2013 primarily due to the write-down of two equity securities. Additionally, gross security gains of $0.6 million and $0.3 million on held-to-maturity securities were realized for the nine months ended September 30, 2013 and 2012, respectively.

The following tables provide information on unrealized losses on investment securities that have been in an unrealized loss position for less than twelve months and twelve months or more as of September 30, 2013 and December 31, 2012:

Unrealized losses on debt securities in the table 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 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 of investment grade quality 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 Federal Home Loan Bank (“FHLB”) of Pittsburgh and FHLB of Cincinnati stock totaling $12.0 million and $21.3 million at September 30, 2013 and December 31, 2012, 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.

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

Basis of presentation — The accompanying unaudited interim financial statements of WesBanco, Inc. and its consolidated subsidiaries (“WesBanco”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2012.

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 2012 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 July 2013, the Financial Accounting Standards Board (the “FASB”) issued an accounting pronouncement to improve the reporting for unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The pronouncement is expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The pronouncement is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s consolidated financial statements.

In February 2013, the FASB issued an accounting pronouncement to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendment does not change the current requirements for reporting net income or other comprehensive income in the financial statements. However, the amendment requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to include references to other disclosures. The pronouncement is effective prospectively for interim and annual reporting periods beginning after December 15, 2012. The adoption of this pronouncement did not have a material impact on WesBanco’s consolidated financial statements.

In December 2011, the FASB issued an accounting pronouncement which requires entities to disclose both gross and net information about instruments and transactions eligible for offset in the statement of financial position, including instruments and transactions subject to master netting arrangements. The scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. The objective of this pronouncement is to enhance disclosures required by GAAP by requiring improved information about financial instruments and derivative instruments that are either offset in accordance with existing GAAP or subject to an enforceable master netting arrangement or similar agreement. This information will enable users of an entity’s financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments. In January 2013, the FASB issued an accounting pronouncement to clarify and limit the scope of the aforementioned pronouncement by more specifically defining transactions eligible for offset. The pronouncements should be applied retrospectively effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The adoption of these pronouncements did not have a material impact on WesBanco’s consolidated financial statements.

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, 2012.

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 2012 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 July 2013, the Financial Accounting Standards Board (the “FASB”) issued an accounting pronouncement to improve the reporting for unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The pronouncement is expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The pronouncement is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this pronouncement is not expected to have a material impact on WesBanco’s consolidated financial statements.

In February 2013, the FASB issued an accounting pronouncement to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendment does not change the current requirements for reporting net income or other comprehensive income in the financial statements. However, the amendment requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to include references to other disclosures. The pronouncement is effective prospectively for interim and annual reporting periods beginning after December 15, 2012. The adoption of this pronouncement did not have a material impact on WesBanco’s consolidated financial statements.

In December 2011, the FASB issued an accounting pronouncement which requires entities to disclose both gross and net information about instruments and transactions eligible for offset in the statement of financial position, including instruments and transactions subject to master netting arrangements. The scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. The objective of this pronouncement is to enhance disclosures required by GAAP by requiring improved information about financial instruments and derivative instruments that are either offset in accordance with existing GAAP or subject to an enforceable master netting arrangement or similar agreement. This information will enable users of an entity’s financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments. In January 2013, the FASB issued an accounting pronouncement to clarify and limit the scope of the aforementioned pronouncement by more specifically defining transactions eligible for offset. The pronouncements should be applied retrospectively effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The adoption of these pronouncements did not have a material impact on WesBanco’s consolidated financial statements.

⁽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 descriptions of risk grades apply to commercial real estate and commercial and industrial loans:

Excellent or minimal risk loans are fully secured by liquid or readily marketable collateral and therefore have virtually no risk of loss. Good or desirable risk loans are extended in the normal course of business to creditworthy borrowers that exhibit a history of positive financial results that are at least comparable to the average for their industry or type of real estate. These loans are expected to perform satisfactorily during most economic cycles and there are no significant external factors that are expected to adversely affect these borrowers more than others in the same industry. Any minor unfavorable characteristics of these loans are outweighed or mitigated by strong positive factors including but not limited to adequate secondary sources of repayment or guarantees.

Fair or acceptable risk loans have a somewhat higher credit risk profile due to specific weaknesses or uncertainties that could adversely impact repayment capacity. Loans in this category generally warrant additional attention or monitoring, or a more rigid loan structure. These loans represent the maximum level of risk accepted in the normal course of lending. Specific issues that may warrant this grade include financial results that are less favorable than the average for the borrower’s industry or type of real estate, cyclical financial results, loans based on projections that have a reasonable probability of being achieved, start-up businesses, construction projects, and other external factors that indicate a higher level of credit risk. Loans that are underwritten primarily on the basis of the repayment capacity or financial condition of guarantors may also be assigned this grade.

Criticized or marginal loans are currently protected but have weaknesses, which, if not corrected, may inadequately protect WesBanco Bank, Inc. (the “Bank”) 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.

The following tables summarize commercial loans by their assigned risk grade:

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 $14.6 million at September 30, 2013 and $17.9 million at December 31, 2012, of which $2.2 and $4.9 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.

The following tables summarize the age analysis of all categories of loans:

Impaired Loans — A loan is considered impaired, based on current information and events, if it is probable that WesBanco will be unable to collect the payments of principal and interest when due according to the contractual terms of the loan agreement. Impaired loans generally included all non-accrual loans and TDRs.

Loans are generally placed on non-accrual status when they become past due 90 days or more unless they are both well-secured and in the process of collection. Loans may also be placed on non-accrual when full collection of principal is in doubt even if payments on such loans remain current, or may remain on non-accrual if they are 90 days or more past due but subsequently brought current and maintained current for at least six consecutive months.

Loans are categorized as TDRs when the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider.

TDRs decreased from December 31, 2012 primarily due to principal reductions and loan sales. The increase in the number of TDR modifications and the number of defaults over the prior year resulted from the implementation of a regulatory requirement in December 2012, to include as TDRs mortgage, home equity and consumer loans discharged in bankruptcy.

As of September 30, 2013, there was one TDR greater than $1.0 million, which was non-accrual, representing $1.5 million or 5.3% of total TDRs, with specific reserves of $0.8 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.

The following tables present details related to loans identified as TDRs during the three and nine months ended September 30, 2013 and 2012, respectively:

Fair Value Disclosures [Abstract]

Fair Value Measurement

NOTE 7. FAIR VALUE MEASUREMENT

Fair value estimates are based on quoted market prices, if available, quoted market prices of similar assets or liabilities, or the present value of expected future cash flows and other valuation techniques. These valuations are significantly affected by discount rates, cash flow assumptions, and risk assumptions used. Therefore, fair value estimates may not be substantiated by comparison to independent markets and are not intended to reflect the proceeds that may be realizable in an immediate settlement of the instruments.

Fair value is determined at one point in time and is not representative of future value. These amounts do not reflect the total value of a going concern organization. Management does not have the intention to dispose of a significant portion of its assets and liabilities and therefore, the unrealized gains or losses should not be interpreted as a forecast of future earnings and cash flows.

The following is a discussion of assets and liabilities measured at fair value on a recurring basis and valuation techniques applied:

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.

Mortgage servicing rights: The fair value of mortgage servicing rights is based on an independent valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions based on management’s best judgment that are significant inputs to the discounting calculations. If the carrying value exceeds fair value, they are considered impaired and are classified within level 3 of the fair value hierarchy as a result.

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 September 30, 2013 and December 31, 2012:

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 and level 2 for the nine months ended September 30, 2013.

The following tables present 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:

⁽¹⁾ Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various level 3 inputs which are not identifiable.

⁽²⁾  Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range and weighted average of appraisal adjustments and liquidation expenses are presented as a percent of the appraisal.

⁽³⁾  Includes estimated liquidation expenses and numerous dissimilar qualitative adjustments by management which are not identifiable.

The estimated fair values of WesBanco’s financial instruments are summarized below:

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, and the credit risk associated with the loan and market factors, including liquidity. The valuation of the loan portfolio reflects discounts that WesBanco believes are consistent with transactions occurring in the marketplace for both performing and distressed loan types. The carrying value that fair value is compared to 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 the 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 broker prices from recent similar sales.

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 9. 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 $0.4 million and $0.3 million as of September 30, 2013 and December 31, 2012, respectively, and is included in other liabilities on the Consolidated Balance Sheets.

Letters of credit are conditional commitments issued by banks to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including normal business activities, bond financing and similar transactions. Letters of credit are considered guarantees. The liability associated with letters of credit was immaterial as of both September 30, 2013 and December 31, 2012.

Contingent obligations to purchase loans funded by other entities include affordable housing plan guarantees and credit card guarantees. Affordable housing plan guarantees are performance guarantees for various building project loans. The guarantee amortizes as the loan balances decrease. Credit card guarantees are credit card balances not owned by WesBanco, whereby the Bank guarantees the performance of the cardholder.

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

(unaudited, in thousands)	September 30, 2013		December 31, 2012
Lines of credit	$	913,457	$	769,525
Loans approved but not closed		201,838		218,531
Overdraft limits		88,025		93,654
Letters of credit		18,922		20,078
Contingent obligations to purchase loans funded by other entities		6,332		6,668

Contingent Liabilities — WesBanco is a party to various legal and administrative proceedings and claims. While any litigation contains an element of uncertainty, management believes that the outcome of such proceedings or claims pending or known to be threatened will not have a material adverse effect on WesBanco’s consolidated financial position, results of operations or cash flows.

Federal Home Loan Bank Borrowings

9 Months Ended

Banking And Thrift [Abstract]

Federal Home Loan Bank Borrowings

NOTE 5. FEDERAL HOME LOAN BANK BORROWINGS

WesBanco is a member of the FHLB System. WesBanco’s FHLB borrowings, which consist of borrowings from both the FHLB of Pittsburgh and the FHLB of Cincinnati, are secured by a blanket lien by the FHLB on certain residential mortgages and other loan types or securities with a market value in excess of the outstanding balances of the borrowings. At September 30, 2013 and December 31, 2012, WesBanco had FHLB borrowings of $59.9 million and $111.2 million, with a weighted-average interest rate of 2.72% and 3.04%, respectively. The decline in borrowings from December 31, 2012 was due to scheduled maturities. The terms of the security agreement with the FHLB include a specific assignment of collateral that requires the maintenance of qualifying mortgage and other types of loans as pledged collateral with unpaid principal amounts in excess of the FHLB advances, when discounted at certain pre-established percentages of the loans’ unpaid principal balances. FHLB stock owned by WesBanco totaling $12.0 million at September 30, 2013 and $21.3 million at December 31, 2012 is also pledged as collateral on these advances. The remaining maximum borrowing capacity by WesBanco with the FHLB at September 30, 2013 and December 31, 2012 was estimated to be approximately $1.5 billion and $1.3 billion, respectively.

Certain FHLB advances contain call features, which allow the FHLB to call the outstanding balance or convert a fixed rate borrowing to a variable rate advance if the strike rate goes beyond a certain predetermined rate. The probability that these advances will be called depends primarily on the level of related interest rates during the call period. Of the $59.9 million outstanding at September 30, 2013, $6.0 million in FHLB convertible advances are subject to call or conversion to a variable rate advance by the FHLB.

The following table presents the aggregate annual maturities and weighted-average interest rates of FHLB borrowings at September 30, 2013 based on their contractual maturity dates and effective interest rates:

(unaudited, dollars in thousands)	Scheduled		Weighted
