Income Taxes [Abstract]
Income Taxes	7. Income Taxes We had $20.7 million of gross unrecognized tax benefits as of August 31, 2012, and $20.9 million as of February 29, 2012. During the six months ended August 31, 2012, we settled federal and state liabilities of $2.8 million related to the Internal Revenue Service audit of fiscal years 2008 through 2010. There were no other significant changes to the gross unrecognized tax benefits as reported for the year ended February 29, 2012, as all activity was related to positions taken on tax returns filed or intended to be filed in the current fiscal year.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
