Discontinued Operations and Disposal Groups [Abstract]
Disposal	Disposal On July 21, 2015, the Company's Board of Directors approved an agreement to sell the Company's education seminars business, CCE, which provided in-person seminars to healthcare professionals and was non-core to the Company’s business. The operating results of CCE were included in the Other Human Capital Management Services segment. See Note 17 - Segment Data for further information. The Company used the net proceeds from the transaction to finance, in part, the Mediscan acquisition in the fourth quarter of 2015. See Note 3 - Acquisitions. Since the disposal of the education seminars business did not represent a strategic shift that would have a major effect on the Company’s operations and financial results, it was not reflected as discontinued operations. On July 27, 2015, the Company entered into an Agreement and Plan of Merger to sell its wholly-owned subsidiary, CCE, to a third party (Buyer) and on August 31, 2015, the sale was completed. The Company received $8.0 million in cash, subject to a net working capital adjustment, of which $0.5 million was held in escrow for a period of 12 months following the closing to provide partial security to the Buyer in the event of any breach of the representations, warranties and covenants of the Company. In September 2016, the full amount of escrow, which had been reflected as an escrow receivable, was released to the Company. The purchase price also included an earnout of up to $0.5 million related to the performance of CCE for the year ended December 31, 2015, which was treated as contingent consideration. The Company assigned no fair value to this earnout as of December 31, 2015 as the performance-based milestones were not met. The original escrow amount was released to the Buyer in the first quarter of 2016. The Company recognized a pre-tax loss of $2.2 million related to the sale of the business, which is included in income (loss) from operations in its consolidated statements of operations for the year ended December 31, 2015. In addition, the Company recorded a tax benefit of $3.5 million from the reversal of valuation allowances associated with this business, resulting in an after-tax gain on the sale of CCE of $1.3 million.
