Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES In December 2017, President Trump signed into law H.R. 1, “An Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018” (this legislation was formerly called the “Tax Cuts and Jobs Act” and is referred to herein as the “U.S. Tax Act”). The U.S. Tax Act provides for significant changes in the U.S. Internal Revenue Code of 1986, as amended. Certain provisions of the U.S. Tax Act are effective during our fiscal year ending November 30, 2018 with all provisions of the U.S. Tax Act effective as of the beginning of our fiscal year ending November 30, 2019. The U.S. Tax Act contains provisions with separate effective dates but is generally effective for taxable years beginning after December 31, 2017. Beginning on January 1, 2018, the U.S. Tax Act lowers the U.S. corporate income tax rate from 35% to 21% on our U.S. earnings from that date and beyond. The revaluation of our U.S. deferred tax assets and liabilities to the 21% corporate tax rate, that was recognized in the first quarter of fiscal 2018, has reduced our net U.S. deferred income tax liability by $376.5 million and is reflected as a reduction in our income tax expense in our results for the six months ended May 31, 2018. The U.S. Tax Act imposes a one-time transition tax on post-1986 earnings of non-U.S. affiliates that have not been repatriated for purposes of U.S. federal income tax, with those earnings taxed at rates of 15.5% for earnings reflected by cash and cash equivalent items and 8% for other assets. We estimate this tax to be $78.6 million, including related additional foreign withholding taxes of $6.3 million associated with previously unremitted prior year earnings of certain foreign subsidiaries that are no longer considered indefinitely reinvested, which we have recognized as a component of our income tax expense for the six months ended May 31, 2018. As we are not a calendar year-end company, certain elements of the transition tax cannot be finalized until the completion of our U.S. tax year ending November 30, 2018. The cash tax effects of this transition tax in the amount of $72.3 million can be remitted in installments over an eight-year period and we intend to do so. In addition to the previously described repatriation tax of $78.6 million, if an actual cash repatriation of the underlying earnings of non-U.S. affiliates occurs we could also be subject to additional foreign withholding taxes and an additional U.S. tax (generally associated with the tax on foreign exchange gains or losses). The Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (SAB 118) on December 23, 2017. SAB 118 provides a one-year measurement period from a registrant’s reporting period that includes the U.S. Tax Act’s enactment date to allow registrants sufficient time to obtain, prepare and analyze information to complete the accounting required under ASC 740 Income Taxes. While based upon estimates and judgments that we believe to be reasonable, the $297.9 million net benefit recognized in the first quarter of 2018 related to the U.S. Tax Act, as described above, is provisional and may change during the measurement period as a result of, among other things, changes in interpretations and assumptions we have made, guidance that may be issued and other actions we may take as a result of the U.S. Tax Act different from that presently assumed. During the three months ended May 31, 2018, there was no change to the $297.9 million provisional net benefit recognized in the first quarter of 2018. Income taxes for the three months ended May 31, 2018 included $2.4 million of discrete tax benefits consisting of the following: (i) $1.1 million of excess tax benefits associated with share-based compensation, and (ii) $1.3 million related to the reversal of unrecognized tax benefits and related interest associated with the expiration of statutes of limitation in non-US jurisdictions. Income taxes for the six months ended May 31, 2018 included $305.4 million of discrete tax benefits consisting of the following: (i) the $297.9 million net benefit associated with the U.S. Tax Act, previously described, (ii) $4.5 million of excess tax benefits associated with share-based compensation, and (iii) $3.5 million related to the reversal of unrecognized tax benefits and related interest associated with the expiration of statutes of limitation in non-US jurisdictions, offset by a $0.5 million net detriment related to the revaluation of deferred tax assets related to legislation enacted in a non-US jurisdiction in our first quarter. Other than the discrete tax benefits mentioned previously and additions for current year tax positions, there were no significant changes to unrecognized tax benefits during the three and six months ended May 31, 2018. Income taxes for the three months ended May 31, 2017 included $8.3 million of discrete tax benefits consisting of the following: (i) $7.0 million related to excess tax benefits associated with share-based compensation, and (ii) and the reversal of unrecognized tax benefits and related interest of $1.3 million associated with the expiration of a statute of limitation in a non-US jurisdiction. Income taxes for the six months ended May 31, 2017 included $10.7 million of discrete tax benefits consisting of the following: (i) $8.6 million related to excess tax benefits associated with share-based compensation, and (ii) the reversal of unrecognized tax benefits and related interest of $2.2 million associated with the expiration of statute of limitations in various jurisdictions, less (iii) a net detriment of $0.1 million resulting from the revaluation of deferred tax assets related to legislation enacted in our first quarter. As of May 31, 2018, we believe the reasonably possible total amount of unrecognized tax benefits that could increase or decrease in the next 12 months as a result of various statute expirations, audit closures, and/or tax settlements would not be material to our consolidated financial statements.
