Remaining Performance Obligations

Master service agreements and other contractual agreements with customers contain customer-specified service requirements, such as discrete pricing for individual tasks. In most cases, our customers are not contractually committed to procure specific volumes of services under these agreements.

Services are generally performed pursuant to these agreements in accordance with individual work orders. An individual work order generally is completed within one year. As a result, our remaining performance obligations under the work orders not yet completed is not meaningful in relation to our overall revenue at any given point in time. We apply the practical expedient in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, and do not disclose information about remaining performance obligations that have original expected durations of one year or less.
