Segment Reporting [Abstract]

Segment Reporting Disclosure

Segment Reporting

ASGN provides information technology ("IT") services and professional solutions across the commercial and government sectors. ASGN operates through two segments, Commercial and Federal Government. The Commercial Segment, which is the largest segment, provides consulting, creative digital marketing, and permanent placement services primarily to large mid-market and Fortune 1000 companies. The Federal Government Segment provides mission-critical solutions to the Department of Defense, the intelligence community, and federal civilian agencies. Virtually all of the Company's revenues are generated in the United States.

Management evaluates the performance of each segment primarily based on revenues, gross profit, and operating income derived directly from internal financial reporting of the segments used for corporate management purposes, which is presented below by segment (in millions):
