Revenue Recognition

On January 1, 2018, the Corporation adopted ASU 2014-09 "Revenue from Contracts with Customers" (Topic 606) and all subsequent ASUs that modified Topic 606. Interest income, net securities gains (losses) and bank-owned life insurance are not included within the scope of Topic 606. For the revenue streams in the scope of Topic 606, service charges on deposits and electronic banking fees, there are no significant judgments related to the amount and timing of revenue recognition. All of the Corporation's revenue from contracts with customers is recognized within noninterest income.

Service charges on deposits: The Corporation earns fees from its deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which include services such stop payment charges, statement rendering and other fees, are recognized at the time the transaction is executed as that is the point in time the Corporation fulfills 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 the Corporation satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance.

Electronic banking fees: The Corporation earns interchange and other ATM related fees from cardholder transactions conducted through the various payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The gross amount of these fees are processed through noninterest income. Other fees, such a transaction surcharges and card replacement fees are withdrawn from the customer's account balance at the time of service.
