Subsequent Events (Unaudited)	19. SUBSEQUENT EVENTS (UNAUDITED) On December 22, 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 will be 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. As the U.S. Tax Act was enacted after our year end of November 30, 2017, it had no impact on our fiscal 2017 financial results. 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. We estimate that the revaluation of our U.S. deferred tax assets and liabilities to the 21% corporate tax rate will reduce our net U.S. deferred income tax liability by approximately $400 million and will be reflected as a reduction in our income tax expense in our results for the quarter ending February 28, 2018. The U.S. Tax Act imposes a 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 in the range of $70 million to $90 million, which we will recognize as a component of income tax expense in our results for the quarter ending February 28, 2018. The cash tax effects of this deemed repatriation can be remitted in installments over an eight-year period and we intend to do so. In addition to the previously described deemed repatriation tax, ranging from $70 million to $90 million, we would also be subject to additional foreign withholding taxes were those related underlying earnings of non-U.S. affiliates subsequently to be repatriated to the U.S. The ultimate impact of the U.S. Tax Act on our reported results in 2018 may differ from the estimates provided herein, possibly materially, due to, 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 contemplated.

19. SUBSEQUENT EVENTS (UNAUDITED)

On December 22, 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 will be 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.

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.
