Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Income tax expense for the quarter was computed in accordance with ASC 740-270 "Income Taxes - Interim Reporting". Under this method, losses from jurisdictions for which a valuation allowance have been provided have not been included in the amount to which the ASC 740-270 rate was applied. Income tax expense of the Company fluctuates primarily due to changes in income mix by jurisdiction, including changes in losses and income from jurisdictions for which a valuation allowance has been provided, and the impact of discrete items in the respective quarter. The income tax benefit for the three months ended January 31, 2018 was $15.6 million; whereas, the income tax expense for the three months ended January 31, 2017 was $11.8 million. On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act of 2017 (the “Tax Reform Act”). The legislation significantly changed U.S. tax law by, among other things, lowering the corporate income tax rate from 35% to 21%, effective January 1, 2018; allowing for the acceleration of expensing for certain business assets; requiring companies to pay a one-time transition tax on certain un-remitted earnings of foreign subsidiaries; and eliminating U.S. federal income tax on dividends from foreign subsidiaries. The rate change is administratively effective as of the beginning of our fiscal year, resulting in the Company using a blended statutory rate for the annual period of 23.33%. The SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. The Company has recognized the provisional tax impacts related to deemed repatriated earnings of $35.9 million tax expense and the revaluation of deferred tax assets and liabilities of $65.0 million tax benefit, and, as a result, the net benefit included in its consolidated financial statements for the quarter ended January 31, 2018 is $29.1 million. The final impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analyses, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, and actions the Company may take as a result of the Tax Reform Act.
