Deposit service charges

Umpqua earns fees from its deposit customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposits accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

Debit and ATM interchange fee income and expenses

Debit and ATM interchange income represent fees earned when a debit card issued by Umpqua is used. Umpqua earns interchange fees from debit cardholder transactions 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. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ debit card. Certain expenses directly associated with the credit and debit card are recorded on a net basis with the interchange income.

Brokerage revenue

As of the three months ended March 31, 2018 and 2017, Umpqua had revenues of $4.2 million and $4.1 million, respectively, for the performance of brokerage services for its clients through Umpqua Investments. Brokerage fees consist of transaction

fees earned from asset management, trade execution and administrative fees from investments. Asset Management fees are variable, since they are based on the underlying portfolio value, which is subject to market conditions and amounts invested by clients. Asset management fees are recognized over the period that services are provided, and when the portfolio values are known or can be estimated at the end of each quarter. Brokerage transaction fees are fixed and determinable, based on security type and trade volume, and are recognized upon trade execution. In addition, revenues are earned from selling insurance and annuity policies. The amount of revenue earned is determined by the value and type of each instrument sold and is recognized when the policy is in force.

Merchant fee income

Merchant fee income represents fees earned by Umpqua for card payment services provided to its merchant customers. Umpqua has a contract with a third party to provide card payment services to merchants that contract for those services. The third party provider passes the payments made by the merchants through to Umpqua. Umpqua, in turn, pays the third party provider for the services it provides to the merchants. These payments to the third party provider are recorded as expenses as a net reduction against fee income. In addition, a portion of the payment received represents interchange fees which are passed through to the card issuing bank. Income is primarily earned based on the dollar volume and number of transactions processed. The performance obligation is satisfied and the related fee is earned when each payment is accepted by the processing network. For the three months ended March 31, 2018 and 2017, Umpqua had merchant processing fee revenue of $841,000 and $962,000, respectively, included in other income.

Credit card and interchange income and expenses

Credit card interchange income represent fees earned when a credit card issued by the Company is used. Similar to the debit card interchange, Umpqua earns an interchange fee for each transaction made with the Umpqua's branded credit cards. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ credit card. Certain expenses and rebates directly related to the credit card interchange contract are recorded net to the interchange income. For the three months ended March 31, 2018 and 2017, credit card and interchange income included in other income was $1.7 million and $1.5 million, respectively.

Gain/loss on other real estate owned, net

Umpqua records a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When Umpqua finances the sale of other real estate owned to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate owned 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 sale, Umpqua adjusts the transaction price and related gain or loss on sale if a significant financing component is present.
