WESBANCO INC Revenue Disclosure

Revenue Recognition— Interest income, net securities gains (losses) and bank-owned life insurance are not in scope of ASC 606, Revenue from Contracts with Customers. For the revenue streams in scope of ASC 606, which include trust fees, service charges on deposits, net securities brokerage revenue, payment processing fees, electronic banking fees, net swap fee and valuation income, mortgage banking income and net gain or loss on sale of other real estate owned and other assets, there are no significant judgments related to the amount and timing of revenue recognition.

Trust fees: Fees are earned over a period of time between monthly and annually, per the related fee schedule. The fees are earned ratably over the period for investment, safekeeping and other services performed by Wesbanco. The fees are accrued when earned based on the daily asset value on the last day of the quarter. In most cases, the fees are directly debited from the customer account. WesMark fees consist of investment advisory fees and shareholder service fees and are paid to Wesbanco by the WesMark mutual funds on a monthly basis for Wesbanco’s involvement with the management of the funds.

Service charges on deposits: There are monthly service charges for both commercial and personal banking customers, which are earned over the month per the related fee schedule based on the customers’ deposits. There are also transaction-based fees, which are earned based on specific transactions or customer activity within the customers’ deposit accounts. These are earned at the time the transaction or customer activity occurs. The fees are debited from the customer account.

Net securities brokerage revenue: Commission income is earned based on customer transactions and management of investments. The commission income from customers’ transactions is recognized when the transaction is complete and approved. Annuity commissions are earned based upon the carrier’s commission rate for the annuity product chosen by the investing customer. The commission income from the management of investments over time is earned continuously over a quarterly period.

Payment processing fees: Payment processing fees are earned from the bill payment and electronic funds transfer (“EFT”) services provided under the name WesPay. The fees are derived from both the individual consumer banking transactions and from businesses or service providers through monthly billing for total transactions occurring. These fees are earned at the time the transaction or customer activity occurs. The fees are debited from the customers’ deposit accounts or charged directly to the business or service provider. Payment processing fees are recorded within other non-interest income on the Consolidated Statements of Income.

Digital banking income: Interchange and ATM fees are earned based on customer and ATM transactions. Revenue is recognized when the transaction is settled.

Net swap fee and valuation income: Fee income is earned when Wesbanco executes interest rate swaps and caps with its commercial banking customers. These swaps and caps are economically hedged by offsetting interest rate swaps and caps that Wesbanco executes with a third party, generating the fee income. The fee income is recognized when the swap or cap transaction is complete and approved by all parties.

Mortgage banking income: Income is earned when Wesbanco-originated loans are sold to an investor on the secondary market. The investor bids on the loans. If the price is accepted, Wesbanco delivers the loan documents to the investor. Once received and approved by the investor, revenue is recognized and the loans are derecognized from the Consolidated Balance Sheet. Prior to the loans being sold, they are classified as loans held for sale. Additionally, the changes in the fair value of the loans held for sale, loan commitments and related derivatives are included in mortgage banking income and are somewhat offset by any deferred direct origination costs, such as mortgage loan officer commissions.

Net gain or loss on sale of other real estate owned and other assets: Net gain or loss on other real estate owned is recorded when the property is sold to a third party and the Bank collects substantially all of the consideration to which it is entitled in exchange for the transfer of the property. Net gain or loss on other assets can include, among other things, the sale of fixed assets, the change in fair value of the underlying investments funded by Wesbanco’s Community Development Corporation (“Wesbanco CDC”) and residual income earned from the sale of Wesbanco’s debit card sponsorship program. Gains or losses are recognized upon receipt of consideration and subsequent transfer of the property for fixed asset sales. The change in fair value of Wesbanco CDC investments occurs upon the change in the underlying investments as these are accounted for utilizing the equity method, and as such, are not within the scope of ASC 606. Residual income from the sale of the debit card sponsorship program is recognized over time as per the signed agreement between Wesbanco and the buyer.
