Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our consolidated interim effective tax rate is based upon our expected annual operating income, statutory tax rates, and income tax laws in the various jurisdictions in which we operate. Significant or unusual items, including adjustments to accruals for tax uncertainties, are recognized in the quarter in which the related event occurs. The effective tax rate of 28.2% for the three months ended July 31, 2016, is based on an expected tax rate of 29.5% on ordinary income for the full fiscal year, as adjusted for the recognition of a net tax benefit related to discrete items arising during the period and interest on previously provided tax contingencies. Our expected tax rate includes current fiscal year additions for existing tax contingency items. As discussed in Note 1, we adopted new accounting guidance for stock-based compensation, including the income tax consequences. As a result, our effective tax rate for the quarter reflects the impact of $2 million of tax benefits related to stock-based compensation that we recognized as a discrete item during the period.
