Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments, Policy [Policy Text Block]	The recorded values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value based on their short-term nature. Long-term debt recorded in the Company’s Condensed Consolidated Balance Sheet at June 30, 2014 was $376.8 million. The fair value of the long-term debt, determined using the quoted price technique based on Level 2 inputs including the yields of comparable companies with similar credit characteristics, was $376.3 million.
Fair Value of Contingent Consideration	In connection with estimating the fair value of the contingent consideration, the Company develops various scenarios (base case, downside case, and upside case) and weights each according to the probability of occurrence. The probabilities range from 10.0 percent to 60.0 percent, with the most significant weighting given to the base case at 60.0 percent for Whitaker and 50.0 percent for CyberCoders. These scenarios are developed based on the expected financial performance of the acquired companies, with revenue growth rates being a primary input to the calculation. These revenue growth rates range from 2.0 percent to 15.0 percent for Whitaker, and from 9.6 percent to 25.0 percent for CyberCoders. An increase or decrease in the probability of achievement of any of these scenarios could result in a significant increase or decrease to the estimated fair value. The fair value is reviewed on a quarterly basis based on the most recent financial performance of the most recent fiscal quarter. An analysis is performed at the end of each fiscal quarter to compare actual results to forecasted financial performance. If performance has deviated from projected levels, the valuation is updated for the latest information available. The significant assumptions that may materially affect the fair value are developed in conjunction with the guidance of division management to ensure that the most accurate and latest financial projections are used and compared with the most recent financial results in the fair value measurement. The liability for contingent consideration is established at the time of the acquisition and is evaluated quarterly. The liability is included in the Condensed Consolidated Balance Sheets in other current liabilities and other long-term liabilities. Fair value adjustments outside of the measurement period are included in the Condensed Consolidated Statements of Operations and Comprehensive Income in selling, general and administrative expenses.

Disclosure of accounting policy for completed business combinations (purchase method, acquisition method or combination of entities under common control). This accounting policy may include a general discussion of the purchase method or acquisition method of accounting (including for example, the treatment accorded contingent consideration, the identification of assets and liabilities, the purchase price allocation process, how the fair values of acquired assets and liabilities are determined) and the entity's specific application thereof. An entity that acquires another entity in a leveraged buyout transaction generally discloses the accounting policy followed by the acquiring entity in determining the basis used to value its interest in the acquired entity, and the rationale for that accounting policy.
