Reportable Segments

Beginning in fiscal 2018, we aligned our operations to better serve our clients and markets, resulting in two renamed reportable segments. Our GSG reportable segment primarily includes activities with U.S. government clients (federal, state and local) and all activities with development agencies worldwide. Our CIG reportable segment primarily includes activities with U.S. commercial clients and all international activities other than work for development agencies. This alignment allows us to capitalize on our growing market opportunities and enhance the development of high-end consulting and technical solutions to meet our growing client demand. We will continue to report the results of the wind-down of our non-core construction activities in the RCM segment. Prior year amounts for reportable segments have been revised to conform to the current-year presentation.

GSG provides consulting and engineering services primarily to U.S. government clients (federal, state and local) and development agencies worldwide. GSG supports U.S. government civilian and defense agencies with services in water, environment, infrastructure, information technology, and emergency management services. GSG also provides engineering design services for municipal and commercial clients, especially in water infrastructure, solid waste, and high-end sustainable infrastructure designs. Additionally, GSG provides a wide range of support to development agencies worldwide.

CIG provides consulting and engineering services primarily to U.S. commercial clients and international clients, both commercial and local government. CIG supports commercial clients across the Fortune 500, oil and gas, energy utilities, and mining markets. CIG also provides infrastructure and related environmental and geotechnical services, testing, engineering and project management services to commercial and local government clients across Canada, in Asia Pacific (primarily Australia and New Zealand), as well as Brazil and Chile. CIG also provides field construction management activities in the United States and Western Canada.

We report the results of the wind-down of our non-core construction activities in the RCM reportable segment. The remaining backlog for RCM as of April 1, 2018 was immaterial as the related projects were substantially completed.

Management evaluates the performance of these reportable segments based upon their respective segment operating income before the effect of amortization expense related to acquisitions, and other unallocated corporate expenses. We account for inter-segment revenues and transfers as if they were to third parties; that is, by applying a negotiated fee onto the costs of the services performed. All significant intercompany balances and transactions are eliminated in consolidation.
