Noncontrolling Interest [Abstract]
Noncontrolling Interest	17. Noncontrolling Interest In the first quarter of fiscal year 2007, we established a joint venture in South Africa, TS Innovations Limited ("Innovations"), with a local South Africa corporation, to assist with our sales efforts as well as to provide consulting services and training to our customers in the Sub-Saharan Africa region. As of November 30, 2011 and 2010, Innovations had total assets of $5.0 million and $5.7 million, respectively. For the years ended November 30, 2011, 2010, and 2009, Innovations had total revenues of $13.1 million, $13.2 million and $7.5 million, respectively. As of November 30, 2011, we owned a 74.9% interest in the joint venture. Because of this majority interest, our Consolidated Financial Statements include the balance sheets, results of operations and cash flows of Innovations, net of intercompany charges. We accordingly eliminated 25.1% of financial results that pertain to the noncontrolling interest; the eliminated amount was reported as a separate line on our Consolidated Statements of Operations and Consolidated Balance Sheets.
