Business Segments

On Assignment provides services through two operating segments, the Apex Segment and the Oxford Segment, with each addressing different sectors of the professional staffing market with distinct business models attuned to those sectors. Businesses in the Apex Segment predominately serve markets with a large and local talent pool, and provide a full range of skills through a network of local offices where clients most value relationship, speed, reliability and price. The Apex Segment provides a broad spectrum of technical, scientific and creative professionals for contract, contract-to-hire and permanent placement positions to Fortune 1000 and mid-market clients across the United States. Our businesses in this segment include Apex Systems, Lab Support and Creative Circle. Businesses in the Oxford Segment predominately serve markets with higher-end, specialized skills through a combination of national recruiting centers and local offices where clients most value the unique skill of the candidate and speed of response. The Oxford Segment provides specialized, niche staffing and consulting services in select skill and geographic markets. Our businesses in this segment include Oxford, CyberCoders and Life Sciences Europe.

The Company’s management evaluates the performance of each segment primarily based on revenues, gross profit and operating income. The information in the following tables is derived directly from the segments’ internal financial reporting used for corporate management purposes. The Company's management does not evaluate, manage or measure performance of segments using asset information, and such information is not readily available. Accordingly, assets by reportable segment are not disclosed.
