Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We account for income taxes under ASC 740, Income Taxes. The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns. We file tax returns in the US federal jurisdiction, as well as various international and state jurisdictions. Although certain years are no longer subject to examinations by the IRS and various state taxing authorities, net operating loss carryforwards generated in those years may still be adjusted upon examination by the IRS or state taxing authorities if they either have been or will be used in a future period. As of February 28, 2015, our federal returns from Fiscal 2011 to present continue to be subject to review by the IRS. With few exceptions, the state returns from Fiscal 2009 to present continue to be subject to review by the taxing jurisdictions. A number of years may elapse before an uncertain tax position is audited and finally resolved, and it is often very difficult to predict the outcome of such audits. As of February 28, 2015, our unrecognized tax benefits were $2.8 million including accrued interest and penalties of $1.1 million. If we were to prevail on all unrecognized tax benefits recorded, $1.9 million of the $2.8 million would benefit the overall effective tax rate. It is our policy to recognize interest and penalties accrued relative to unrecognized tax benefits as tax expense. It is reasonably possible that the amount of unrecognized tax benefits with respect to our other unrecognized tax positions will increase or decrease during the next twelve months; however, an estimate of the amount or range of the change cannot be made at this time.
