NONINTEREST INCOME

On January 1,2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and all subsequent ASUs that modified Topic 606. The standard applies to certain revenue streams included in noninterest income on our unaudited Consolidated Statements of Income, discussed in more detail below. See Note 1 for further information about our adoption of ASU 2014-09, and Note 12 for further information about the disaggregation of noninterest income by segment.

Credit/debit card and ATM income

The following table presents the components of credit/debit card and ATM income:



	Three Months Ended June 30,				Six Months Ended June 30,
	2018		2017		2018		2017
Bailment fees	$	6,588	$	5,160	$	12,681	$	9,863
Interchange fees	3,847		3,498		7,307		6,696
Other card and ATM fees	274		267		526		497
Total credit/debit card and ATM income	$	10,709	$	8,925	$	20,514	$	17,056

Credit/debit card and ATM income is primarily composed of bailment fees which are earned from bailment arrangements with our customers. Bailment arrangements are legal relationships in which property is delivered to another party's temporary custody and control without a transfer of ownership. The party receiving the property (the bailee) has possession and control of the property and is obligated to take reasonable care of the property. The party who transferred the property (the bailor) retains ownership interest of the property. In the event that the bailee files for bankruptcy protection, the property is not included in the bailee's assets. The bailee pays an agreed-upon fee for the use of the bailor's property in exchange for the bailor allowing use of the assets at the bailee's site. Bailment fees are earned from cash that is owned by WSFS but available for customers' use at an offsite location, such as cash located in an ATM at a customer's place of business. This revenue stream generates fee income through monthly billing for bailment services.

Credit/debit card and ATM income also includes interchange fees. Interchange fees are paid by a merchant's bank to a bank that issued the debit or credit card used in a transaction to compensate the issuing bank for the value and benefit the merchant receives from accepting electronic payments. These revenue streams generate fee income at the time a transaction occurs and are recorded as revenue at the time of the transaction.

Investment management and fiduciary income

The following table presents the components of investment management and fiduciary income:



	Three Months Ended June 30,				Six Months Ended June 30,
	2018		2017		2018		2017
Trust fees	$	6,118	$	4,977	$	11,366	$	9,273
Wealth management and advisory fees	4,126		3,858		8,067		7,601
Total investment management and fiduciary income	$	10,244	$	8,835	$	19,433	$	16,874

Investment management and fiduciary income is primarily composed of trust fees and wealth management and advisory fees. Trust fees are based on revenue earned from investment and trustee services to families and individuals across the U.S.; custody, escrow and trustee services on structured finance transactions; indenture trustee, administrative agent and collateral agent services to institutions and corporations; and commercial domicile and independent director services. Most fees are flat fees, except for a portion of personal and corporate trustee fees where we earn a percentage on the assets under management. This revenue stream primarily generates fee income through monthly, quarterly and annual billings for services provided.

Wealth management and advisory fees consists of fees from Cypress, West Capital, Powdermill, WSFS Wealth Client Management, WSFS Wealth Investments and Christiana Trust. Wealth management and advisory fees are based on revenue earned from services including asset management, financial planning, family office, and brokerage. The fees are based on the market value of assets, are assessed as a flat fee, or are brokerage commissions. This revenue stream primarily generates fee income through quarterly and annual billing for the services.

Deposit service charges

The following table presents the components of deposit service charges:



	Three Months Ended June 30,				Six Months Ended June 30,
	2018		2017		2018		2017
Service fees	$	2,634	$	2,527	$	5,214	$	4,923
Return and overdraft fees	1,893		1,842		3,777		3,687
Other deposit service fees	137		191		303		347
Total deposit service charges	$	4,664	$	4,560	$	9,294	$	8,957

Deposit service charges includes revenue earned from our core deposit products, certificates of deposit, and brokered deposits. We generate revenues from deposit service charges primarily through service charges and overdraft fees. Service charges consist primarily of monthly account maintenance fees, cash management fees, foreign ATM fees and other maintenance fees. All of these revenue streams generate fee income through service charges for monthly account maintenance and similar items, transfer fees, late fees, overlimit fees, and stop payment fees. Revenue is recorded at the time of the transaction.

Other income

The following table presents the components of other income:



	Three Months Ended June 30,				Six Months Ended June 30,
	2018		2017		2018		2017
Managed service fees	3,105		2,671		5,931		5,290

Total other income	$	7,111	$	6,051	$	13,019	$	11,246

Other income consists of managed service fees, which are primarily courier fees related to cash management, currency preparation, ATM insurance and other miscellaneous products and services offered by the Bank. These fees are primarily generated through monthly billings or at the time of the transaction.

Arrangements with multiple performance obligations

Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on the prices charged to customers.

Practical expedients and exemptions

We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.
