Income Tax And Non Income Tax Disclosure [Abstract]
Income Tax And Non Income Tax Disclosure	Income Taxes and Other Taxes Income Taxes In calculating the provision for income taxes on an interim basis, the Company uses an estimate of the annual effective tax rate based upon the facts and circumstances known and applies that rate to its year-to-date earnings or losses. The Company’s effective tax rate is based on expected income and statutory tax rates and takes into consideration permanent differences between financial statement and tax return income applicable to the Company in the various jurisdictions in which the Company operates. The effect of discrete items, such as changes in estimates, changes in enacted tax laws or rates or tax status, and unusual or infrequently occurring events, is recognized in the interim period in which the discrete item occurs. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or as the result of new judicial interpretations or regulatory or tax law changes. The Company’s annual effective tax rate, exclusive of discrete items and unbenefitted foreign losses, used to calculate the interim tax provision is expected to be 39.0% resulting in a tax rate, inclusive of discrete items and unbenefitted foreign losses, of 37.3% for the three month period ended August 31, 2014. The Company, including its domestic subsidiaries, files a consolidated U.S. income tax return, and also files tax returns in various states and other local jurisdictions. Also, certain subsidiaries of the Company file income tax returns in foreign jurisdictions. The Company is routinely audited by various tax authorities. The Company is currently under audit by the Internal Revenue Service for fiscal years ended May 31, 2011, 2012 and 2013. The Company is currently under audit by New York State for fiscal years ended May 31, 2009, 2010, 2011 and 2012 and by New York City for fiscal years ended May 31, 2008, 2009 and 2010. If any of these tax examinations are concluded within the next twelve months, the Company will make any necessary adjustments to its unrecognized tax benefits. Non-income Taxes The Company is subject to tax examinations for sales-based taxes. A number of these examinations are ongoing and, in certain cases, have resulted in assessments from taxing authorities. The Company assesses sales tax contingencies for each jurisdiction in which it operates, considering all relevant facts including statutes, regulations, case law and experience. Where a sales tax liability with respect to a particular jurisdiction is probable and can be reliably estimated, the Company has made accruals for these matters which are reflected in the Company’s condensed consolidated financial statements.
