Accounting Policies [Abstract]
Trade and Other Accounts Receivable, Unbilled Receivables, Policy [Policy Text Block]	Unbilled Receivables A significant portion of the unbilled receivables presented in the Condensed Consolidated Balance Sheets relate to our Healthcare Claims Recovery Audit services as we generally cannot invoice the prime contractors for whom we operate as a subcontractor under the Medicare RAC program until cash is collected by the prime contractors. These unbilled receivables, net of the related reserves, were $7.9 million and $9.6 million as of September 30, 2013 and December 31, 2012, respectively. As of November 1, 2013, we billed $0.3 million of the unbilled receivables relating to the Medicare RAC program that were outstanding as of September 30, 2013.

Disclosure of accounting policy for treatment of receivables that are billable but have not been billed as of the balance sheet date.
