Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recognize a liability or asset for the deferred tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. These temporary differences will result in taxable or deductible amounts in future years when reported amounts of the assets or liabilities are recovered or settled. The deferred tax assets are periodically reviewed for recoverability. Accounting guidance for uncertain tax positions prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. We recognize the tax impact from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax impact recognized in the financial statements from such a position is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. We recognize interest, penalties and foreign currency gains and losses with respect to uncertain tax positions as components of our income tax provision. Accrued interest and penalties are included within accrued expenses in the consolidated balance sheet. Significant judgment is required in the identification of uncertain tax positions and in the estimation of penalties and interest on uncertain tax positions. There were no uncertain tax positions in fiscal 2016 and 2015. We are subject to taxation in the U.S., as well as various state and foreign jurisdictions. We have substantially settled all income tax matters for the United States federal jurisdiction for years through fiscal 2011. Major state jurisdictions have been examined through fiscal years 2004 and 2005, and foreign jurisdictions have not been examined for their respective initial statutory periods of approximately 3 years.

These temporary differences will result in taxable or deductible amounts in future years when reported amounts of the assets or liabilities are recovered or settled.
