REVENUE FROM CONTRACTS WITH CUSTOMERS

The Corporation adopted Accounting Standards Update (ASU) 2014-9, “Revenue from Contracts with Customers (Topic 606)” using the modified retrospective method applied to all contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASU 2014-9 while prior period amounts continue to be reported in accordance with legacy GAAP. The adoption of ASU 2014-9 did not result in a change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded.

Management determined that the primary sources of revenue emanating from interest and dividend income on loans and investment securities along with non-interest revenue resulting from security gains, loan servicing, gains on the sale of loans, commitment fees, fees from financial guarantees, certain credit cards fees, gains (losses) on sale of other real estate owned, is not within the scope of (ASU) 2014-9. As a result, no changes were made during the period related to these sources of revenue, which comprised 90.8% and 90.7% of the total revenue of the Corporation for the three and six months ended June 30, 2018, respectively.

The following tables depict the disaggregation of revenue derived from contracts with customers to depict the nature, amount, timing, and uncertainty of revenue and cash flows for the three and six months ended June 30, 2018 and 2017.

The types of non-interest income within the scope of the standard that is material to the consolidated financial statements are services charges on deposit accounts, wealth and asset management fee income, and card processing and interchange income.

Service charges on deposit accounts: The Corporation earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH 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. Services charges on deposits are withdrawn from the customer’s account balance.

Wealth and asset management fees: The Corporation earns wealth and asset management fees from its contracts with trust and brokerage customers to manage assets for investment, and/or to transact on their accounts. These fees are primarily earned over time as the Corporation provides the contracted monthly or quarterly services and are generally assessed based on a tiered scale of the market value of assets under management at month end. Fees for these services are billed to customers on a monthly or quarterly basis and are recorded as revenue at the end of the period for which the wealth and asset management services have been performed. Other performance obligations, such as the delivery of account statements to customers, are generally considered immaterial to the overall transaction price.

Card processing and interchange income: The Corporation earns interchange fees from check card and credit card transactions conducted through the Visa payment network. 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.

Other income: The Corporation's other income includes sources such as bank owned life insurance, certain service fees, gains (losses) on sales of fixed assets, and gains (losses) on sale of other real estate owned. The service fees are recognized in the same manner as the service charges mentioned above. While gains on the sale of other real estate owned are generally within the scope of (ASU) 2014-9, the Corporation does not finance the sale of transactions and as such there is no change in revenue recognition.
