Segment Reporting [Abstract]

Segment Reporting

Segment Reporting.The Company has four reportable segments: Apex, Oxford, Physician, and Life Sciences Europe. During the quarter ended March 31, 2014, the Company underwent a realignment of the former Life Sciences segment. As a result of this realignment, Lab Support U.S. is now included in the Apex segment; Valesta U.S. is now included in the Oxford segment; and the Life Sciences Europe segment includes Lab Support Europe, Valesta Europe, and Sharpstream. During 2013, the Company sold its Nurse Travel and Allied Healthcare divisions. See Note 4 Discontinued Operations for further information. The realignment and divestitures resulted in changes to the internal reporting package reviewed by the Chief Operating Decision Maker ("CODM"), and the Healthcare segment no longer exists. Health Information Management, formerly included in the Healthcare Segment, is included in the Oxford Segment and unallocated corporate expenses are separately disclosed in order to align with the revised internal reporting package reviewed by the CODM. All prior periods have been retrospectively restated to conform to the current presentation.

The Company’s management evaluates the performance of each segment primarily based on revenues, gross profit, and operating income. The information in the following table 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.

The following tables present revenues, gross profit, operating income and amortization by reportable segment (in thousands):
