A description of the Company’s revenue streams accounted for under ASC 606 follows:

Service charges on deposit accounts: The Company earns fees from its deposits customers for transaction-based, account maintenance, and overdraft fees. 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 point in time the Company 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 Company 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 Service charges on deposits are withdrawn from the customer’s account balance.

Interchange income: The Company earns interchange fees from debit cardholder 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. Interchange income is presented gross of cardholder rewards. Cardholder rewards are included in other expenses in the statement of income. Cardholder rewards reduced interchange income by $134 thousand, $129 thousand and $124 thousand for 2018, 2017, and 2016, respectively.

Wealth management fees (gross): The Company earns wealth management fees from its contracts with trust customers to manage assets for investment, and/or to transact on their accounts. These fees are primarily earned over time as the Company provides the contracted monthly or quarterly services and are generally assessed based on a tiered scale of the market value of AUM at month-end. Fees that are transaction based, including trade execution services, are recognized at the point in time that the transaction is executed (i.e. trade date).

Investment brokerage fees (net): The Company earns fees from investment brokerage services provided to its customers by a third-party service provider. The Company receives commissions from the third-party service provider twice a month based upon customer activity for the month. The fees are recognized monthly and a receivable is recorded until commissions are generally paid by the 15^th of the following month. Because the Company (i) acts as an agent in arranging the relationship between the customer and the third-party service provider and (ii) does not control the services rendered to the customers, investment brokerage fees are presented net of related costs.

Gains/(losses) on sales of OREO: The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform its obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain/(loss) on sale if a significant financing component is present. The Company recorded a loss on sale of OREO of $58 thousand for 2018 and a gain of $5 thousand in 2016. The Company did not record a gain or loss in 2017.
