Commitments and Contingencies Disclosure [Abstract]
Litigation	Litigation On May 24, 2012, a complaint was filed against the Company in the United States District Court for the District of New Jersey alleging, among other things, that the Company failed to pay overtime compensation to a purported class of certain independent contractor examiners who, the complaint alleges, should be treated as employees for purposes of federal law. The complaint seeks an award of an unspecified amount of allegedly unpaid overtime wages to certain examiners. The Company filed an answer denying the substantive allegations therein. As of the date of this filing, the Magistrate Judge is considering the Company’s Motion to Reconsider an earlier Report and Recommendation conditionally certifying the class of all contract examiners from August 16, 2010 to the present. If the Magistrate's decision stands, notice will be sent to contractors who performed work for the Company within this time period. The claim is not covered by insurance, and the Company is incurring legal costs to defend the litigation which are recorded in continuing operations. This matter relates to the former Portamedic service line for which the Company retained liability. The Company has determined that losses related to the remaining complaint are not estimable or probable. On July 30, 2013, a complaint was filed against the Company in the California Superior Court, San Bernadino County, on behalf of a putative class of employees alleging, among other things, that the Company failed to pay wages and other compensation as required by state law. The complaint sought award of an unspecified amount of damages and penalties. The Company has denied all of the allegations in the case and believes them to be without merit. The Company settled the individual claim with the named plaintiff in July 2014 with prejudice. As a part of the settlement, the named plaintiff agreed to dismiss the class claims, without prejudice. As a result, the Company recorded an immaterial charge during the year ended December 31, 2014 for the settlement amount as a component of discontinued operations in the accompanying consolidated statement of operations. The Company is a party to a number of other legal actions arising in the ordinary course of its business. In the opinion of management, the Company has substantial legal defenses and/or insurance coverage with respect to all of its pending legal actions. Accordingly, none of these actions is expected to have a material adverse effect on the Company’s liquidity, its consolidated results of operations or its consolidated financial position.
