REVENUE FROM CONTRACTS WITH CUSTOMERS

Interest income, loan fees, realized securities gains and losses, bank owned life insurance income and mortgage banking revenue are not in the scope of ASC Topic 606, Revenue from Contracts with Customers. With the exception of gains or losses on sales of foreclosed properties, all of our revenue from contracts with customers in the scope of ASC 606 is recognized within Noninterest Income in the Consolidated Statements of Income. Incremental costs of obtaining a contract are expensed when incurred when the amortization period is one year or less.

A description of our significant sources of revenue accounted for under ASC 606 follows:

Service fees on deposit accounts are fees we charge our deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which are earned based on specific transactions or customer activity within a customer’s deposit account, are recognized at the time the related transaction or activity occurs, as it is at this point when we fulfill the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which Summit satisfied the performance obligation. Overdraft fees are recognized when the overdraft occurs. Service fees on deposit accounts are paid through a direct charge to the customer’s account.

Bank card revenue is comprised of interchange revenue and ATM fees. Interchange revenue is earned when Summit’s debit and credit cardholders conduct transactions through Mastercard and other payment networks. Interchange fees represent a percentage of the underlying cardholder’s transaction value and are generally recognized daily, concurrent with the transaction processing services provided to the cardholder. ATM fees are earned when a non-Summit cardholder uses a Summit ATM. ATM fees are recognized daily, as the related ATM transactions are settled.

Trust and wealth management fees consist of 1) trust fees and 2) commissions earned from an independent, third-party broker-dealer. We earn trust fees from our contracts with trust clients to administer or manage assets for investment. Trust fees are earned over time (generally monthly) as Summit provides the contracted services and are assessed based on the value of assets under management at each month-end. We earn commissions from investment brokerage services provided to our clients by an independent, third-party broker-dealer. We receive monthly commissions from the third-party broker-dealer based upon client activity for the previous month.

Insurance commissions principally consisted of commissions we earned as agents of insurers for selling group employee benefit and property and casualty insurance products to clients. Group employee benefit insurance commissions were recognized over time (generally monthly) as the related customary implied servicing obligations of group policyholders were fulfilled. Property and casualty insurance commissions were recognized using methods which approximated the time of placement of the underlying policy. We were paid insurance commissions ratably as the related policy premiums were paid by clients.
