Restatement of Financial Statement [Abstract]
Restatement of Financial Statement	The September 30, 2011 consolidated financial statements included in our Original Form 10-K filed on December 20, 2011, contained errors primarily related to the understatement of our vacation accrual that should have been recorded at September 30, 2008 and in each subsequent annual and interim period to September 30, 2011. Additionally, for all restated periods we recorded other immaterial adjustments. These adjustments included, but were not limited to, recording billing, payroll and other accruals, and the associated revenue impacts, in the proper accounting period. Accordingly, the September 30, 2011 consolidated financial statements, and all quarterly periods therein, were restated to properly record these transactions and other immaterial adjustments. Refer to our amended form 10-K/A for a more detailed explanation. In addition, we have restated the Statement of Cash Flows and segment information for the three months ended December 31, 2010 to correct for these errors in these financial statements.
