Income Taxes	NOTE 12. INCOME TAXES At the end of each interim period, the Company estimates the annual effective tax rate and applies that rate to its ordinary quarterly earnings. The tax expense or benefit related to significant, unusual or extraordinary items that will be separately reported or reported net of their related tax effect are individually computed and recognized in the interim period in which those items occur. In addition, the effects of changes in enacted tax laws or rates or tax status are recognized in the interim period in which the change occurs. For the three months ended September 30, 2018, the Company recorded a tax charge of $50 million on pre-tax income of $178 million resulting in an effective tax rate that was higher than the U.S. statutory tax rate. The higher tax rate was primarily due to valuation allowances being recorded against tax benefits in certain foreign jurisdictions with operating losses and the impact from foreign operations which are subject to higher tax rates. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act includes significant changes to the U.S. corporate income tax system including, among other things, lowering the U.S. statutory federal tax rate to 21%. The reduction of the U.S. corporate tax rate caused us to adjust our U.S. deferred tax assets and liabilities to the lower federal rate of 21% at the fiscal year ended June 30, 2018. The Tax Act added many new provisions, including a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries (“transition tax”), changes to bonus depreciation, limits on deductions for executive compensation and interest expense, a tax on global intangible low-taxed income (“GILTI”), the base erosion anti-abuse tax (“BEAT”) and a deduction for foreign-derived intangible income. The Company has elected to account for the tax on GILTI and BEAT as a period cost and thus has not adjusted any net deferred tax assets of its foreign subsidiaries for the new tax. However, the Company has considered the potential impact of GILTI and BEAT on its U.S. federal net operating loss (“NOL”) carryforward and determined that the projected tax benefit to be received from its NOL carryforward may be reduced due to these provisions. The changes included in the Tax Act are broad and complex. The SEC issued Staff Accounting Bulletin No. 118 (SAB 118), as amended by ASU 2018-05, which provides guidance for companies related to the Tax Act. ASU 2018-05 allows for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts. The Company’s accounting for the tax effects of the Tax Act will be completed during this measurement period and is expected to be finalized in the second quarter of fiscal 2019 pending further SEC guidance. The final transition impacts of the Tax Act may differ from the Company’s current estimates, possibly materially, due to, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the Company has utilized to calculate the transition impacts. In accordance with SAB 118, the Company has made reasonable estimates related to (1) the remeasurement of U.S. deferred tax balances for the reduction in the tax rate, (2) the liability for the transition tax and (3) the partial valuation allowance recorded against its federal NOL carryforward due to the impact of the GILTI and BEAT provisions. As a result, the Company recognized a net provisional income tax expense of $237 million associated with these items in the fiscal year ended June 30, 2018. For the three months ended September 30, 2018, the Company has not made any adjustments to the provisional amounts recorded as of June 30, 2018. Management assesses available evidence to determine whether sufficient future taxable income will be generated to permit the use of existing deferred tax assets. Based on management’s assessment of available evidence, it has been determined that it is more likely than not that certain deferred tax assets in U.S. Federal, State and foreign jurisdictions may not be realized and therefore, a valuation allowance has been established against those tax assets. For the three months ended September 30, 2017, the Company recorded a tax charge of $54 million on pre-tax income of $141 million, resulting in an effective tax rate that was higher than the U.S. statutory tax rate. The higher tax rate was primarily due to valuation allowances being recorded against tax benefits in certain foreign jurisdictions with operating losses. The Company’s tax returns are subject to on-going review and examination by various tax authorities. Tax authorities may not agree with the treatment of items reported in our tax returns, and therefore the outcome of tax reviews and examinations can be unpredictable. The Company is currently undergoing tax examinations by the Internal Revenue Service (“IRS”), various U.S. state and foreign jurisdictions. During the year ended June 30, 2018, the IRS commenced an audit of the Company for the year ended June 30, 2014. The Company believes it has appropriately accrued for the expected outcome of uncertain tax matters and believes such liabilities represent a reasonable provision for taxes ultimately expected to be paid. However, the Company may need to accrue additional income tax expense and our liability may need to be adjusted as new information becomes known and as these tax examinations continue to progress, or as settlements or litigations occur. The Company paid gross income taxes of $29 million and $48 million during the three months ended September 30, 2018 and 2017 and received tax refunds of $10 million and nil, respectively.

At the end of each interim period, the Company estimates the annual effective tax rate and applies that rate to its ordinary quarterly earnings.
