Business Segment Information [Abstract]

Business Segment Information

10.    Business Segment Information

The Company reports operating results and financial data in two segments: domestic operations and international operations. Domestic operations provide professional services and information technology solutions to its customers. Its customers are primarily U.S. federal government agencies. The Company does not measure revenue or profit by its major service offerings, either for internal management or external financial reporting purposes, as it would be impractical to do so. In many cases more than one offering is provided under a single contract, to a single customer, or by a single employee or group of employees, and segregating the costs of the service offerings in situations for which it is not required would be difficult and costly. The Company also serves customers in the commercial and state and local government sectors and, from time to time, serves a number of agencies of foreign governments. The Company places employees in locations around the world in support of its clients. International operations offer services to both commercial and non-U.S. government customers primarily through the Company's data information and knowledge management services, business systems solutions, and enterprise IT and network services lines of business. The Company evaluates the performance of its operating segments based on net income. Summarized financial information concerning the Company's reportable segments is as follows (in thousands):
