Reportable Segments

Our reportable segments are described as follows:

WEI: WEI provides consulting and engineering services worldwide for a broad range of water and infrastructure-related needs in both developed and emerging economies. WEI supports both public and private clients including federal, state/provincial, and local governments, and global and local commercial clients. The primary markets for WEI’s services include water resources analysis and water management, environmental restoration, government consulting, and a broad range of civil infrastructure master planning and engineering design for facilities, transportation, and regional and local development. WEI’s services span from early data collection and monitoring, to data analysis and information technology, to science and engineering applied research, to engineering design, to construction management and operations and maintenance.

RME: RME provides consulting and engineering services worldwide for a broad range of resource management and energy needs. RME supports both private and public clients, including global industrial and commercial clients, U.S. federal agencies in large scale remediation, and major international development agencies. The primary markets for RME’s services include natural resources, energy, international development, remediation, waste management and utilities. RME’s services span from early data collection and monitoring, to data analysis and information technology, to science and engineering applied research, to engineering design, to construction management and operations and maintenance. RME also supports engineering, procurement and construction management (“EPCM”) for full service implementation of commercial projects.

RCM: We report the results of the wind-down of our non-core construction activities in the RCM reportable segment. The remaining work to be performed in this segment will be substantially completed in calendar 2017.

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 sales and transfers as if the sales and transfers 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. In fiscal 2016, the Corporate segment operating losses included $19.5 million of acquisition and integration expenses, as described in Note 5, "Mergers and Acquisitions ".
