Revenue Recognition

Revenues from contracts with customers are generated in three segments: temporary and consultant staffing, permanent placement staffing, and risk consulting and internal audit services. Revenues are recognized when promised goods or services are delivered to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

Net service revenues, as presented on the unaudited Condensed Consolidated Statements of Operations, represent services rendered to customers less variable consideration, such as sales adjustments and allowances. Reimbursements, including those related to travel and out-of-pocket expenses, are recorded on a gross basis and included in net service revenues, with equivalent amounts of reimbursable expenses included in direct costs of services.

Temporary and consultant staffing revenues. Temporary and consultant staffing revenues from contracts with customers are recognized in the amount to which the Company has a right to invoice, when the services are rendered by the Company’s temporary employees.

The Company records temporary and consultant staffing revenue on a gross basis as a principal versus on a net basis as an agent in the presentation of revenues and expenses. The Company has concluded that gross reporting is appropriate because the Company (i) has the risk of identifying and hiring qualified employees, (ii) has the discretion to select the employees and establish their price and duties and (iii) bears the risk for services that are not fully paid for by customers. Fees paid to Time Management or Vendor Management service providers selected by clients are recorded as a reduction of revenues, as the Company is not the primary obligor with respect to those services. Employees placed on temporary assignment by the Company are the Company’s legal employees while they are working on assignments. The Company pays all related costs of employment, including workers’ compensation insurance, state and federal unemployment taxes, social security and certain fringe benefits. The Company assumes the risk of acceptability of its employees to its customers.

Permanent placement staffing revenues. Permanent placement staffing revenues from contracts with customers are primarily recognized when employment candidates accept offers of permanent employment. The Company has a substantial history of estimating the financial impact of permanent placement candidates who do not remain with its clients through the 90-day guarantee period. These amounts are established based primarily on historical data and are recorded as liabilities. Fees to clients are generally calculated as a percentage of the new employee’s annual compensation. No fees for permanent placement services are charged to employment candidates.

Risk consulting and internal audit revenues. Risk consulting and internal audit services generally contain one or more performance obligation(s) which are satisfied over a period of time. Revenues are recognized over time as the performance obligations are satisfied, because the services provided do not have any alternative use to the Company, and contracts generally include language giving the Company an enforceable right to payment for services provided to date. Revenue is measured using cost incurred relative to total estimated cost for the engagement to measure progress towards satisfying the Company's performance obligations. Cost incurred represents work performed and thereby best depicts the transfer of control to the customer.

Payment terms in our contracts vary by the type and location of our customer and the services offered. The term between invoicing and when payment is due is not significant.

Contracts with multiple performance obligations are recognized as performance obligations are delivered, and contract value is allocated based on relative stand-alone selling values of the services and products in the arrangement. As of the quarter ended March 31, 2018, aggregate transaction price allocated to the performance obligations that are unsatisfied for contracts with an expected duration of greater than one year was $84.1 million. Of this amount, substantially all is expected to be recognized within the next twelve months. There were no revenues recognized in the quarter ended March 31, 2018 related to performance obligations satisfied or partially satisfied in previous periods.

Contract assets are recorded when services are performed in advance of the Company’s unconditional right to payment. Contract assets as of January 1, 2018 and March 31, 2018 were not material.

Contract liabilities are recorded when cash payments are received or due in advance of performance and are reflected in Accounts payable and accrued expenses on the unaudited Condensed Consolidated Balance Sheet. The following table sets forth the activity in contract liabilities from January 1, 2018 through March 31, 2018 (in thousands):
