Segment Reporting [Abstract]

Reportable Segments

Reportable Segments

We manage our operations under two 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 international clients other than development agencies.

Our reportable segments are described as follows:

GSG:    GSG provides high-end consulting and engineering services primarily to U.S. government clients (federal, state and local) and international development agencies worldwide. GSG supports U.S. government civilian and defense agencies with services in water, environment, sustainable infrastructure, information technology and disaster management. GSG also provides engineering design services for U.S. based federal and municipal clients, especially in water infrastructure, flood protection and solid waste. GSG also leads our support for development agencies worldwide, especially in the United States, United Kingdom and Australia.

CIG:    CIG primarily provides high-end consulting and engineering services to U.S. commercial clients, and international clients inclusive of the commercial and government sectors. CIG supports commercial clients worldwide in renewable energy, industrial, high-performance buildings and aerospace markets. CIG also provides sustainable infrastructure and related environmental, engineering and project management services to commercial and local government clients across

Canada, in Asia Pacific (primarily Australia and New Zealand), Europe, the United Kingdom and South America (primarily Brazil).

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. In fiscal 2023, our Corporate segment operating losses included $33.2 million of acquisition and integration expenses as described in Note 5, "Acquisitions". We also recorded a $16.4 million ($6.8 million in GSG, $8.3 million in CIG and $1.3 million in Corporate) non-cash impairment charge related to our ROU operating lease assets in fiscal 2023 (see Note 10, "Leases" for more information).

The following tables present summarized financial information of our reportable segments (in thousands):
