Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On October 1, 2014, the Company sold certain assets related to its Chicago, Illinois-based consulting business that were previously acquired in November 2010 from TJG Holdings LLC to Salo, LLC, a Minnesota limited liability company. The Company received an initial cash payment of $1.1 million in connection with the closing of the transaction and will receive payment for working capital transferred to the buyer. In addition, the Company may receive up to $0.9 million in earn-out payments based on certain revenue recognized by the buyer in relation to the acquired business during the year following the closing date. On October 24, 2014, our Board of Directors authorized a $20.0 million increase to the Company's stock repurchase program, increasing the total stock repurchase program since its inception to $40.0 million, and extended the duration of the program to December 31, 2015. From the February 2014 announcement of the Company’s current stock repurchase program through September 30, 2014, the Company has repurchased 3.1 million shares, or 10.4% of its common stock outstanding on the date of the announcement, for an aggregate cost of $20.0 million.
