Income Tax Disclosure [Abstract]
INCOME TAXES	Income Taxes In December 2017, the 2017 Tax Act was enacted in the United States. Among its many provisions, the 2017 Tax Act imposed a mandatory one-time transition tax on undistributed international earnings (Transition Tax), reduced the U.S. corporate income tax rate from 35% to 21% and created a territorial tax system. As a result of the enactment of the 2017 Tax Act, the Company recognized a provisional net income tax benefit of $39 million in 2017. Beginning January 1, 2018, foreign earnings of the Company's international subsidiaries are generally exempt from U.S. Federal income tax upon repatriation. Notwithstanding these changes, certain non-U.S. withholding taxes and foreign exchange gains and losses will continue to be applicable upon the future repatriation of foreign earnings. During 2018, the Internal Revenue Service (IRS) and the U.S. Department of Treasury (Treasury) issued additional guidelines and clarifying regulations related to the implementation of the 2017 Tax Act. The Company expects that additional guidance will continue to be issued in future periods. As this guidance is issued, the Company will continue to evaluate the information to determine whether any additional adjustments to its tax provisions are required. The 2017 Tax Act included provisions for Global Intangible Low-Taxed Income (GILTI) under which taxes on foreign income are imposed on the excess of a deemed return on tangible assets of certain foreign subsidiaries and for Base Erosion and Anti-Abuse Tax (BEAT) under which taxes are imposed on certain base eroding payments to affiliated foreign companies. Consistent with U.S. GAAP, the Company will treat BEAT as discrete adjustments to the income tax provision when incurred in future periods for which no deferred taxes are required to be provided and has made an accounting policy election to treat GILTI taxes in a similar manner. No provision for income taxes related to GILTI has been recorded through September 30, 2018. No provision for BEAT was recorded until the second quarter of 2018 when an estimated BEAT income tax expense of $2.0 million was recognized. This amount was reversed in the third quarter of 2018 based upon updated BEAT calculations and projections as of September 30, 2018. The Company elected to adopt the Securities and Exchange Commission issued guidance that allows for a measurement period, not to exceed one year after the enactment date of the 2017 Tax Act, to finalize the recording of the related tax impacts. The Company expects to finalize its tax positions and calculations in the fourth quarter of 2018 though a possibility remains that additional guidance and regulations could be issued beyond 2018 that could impact the amounts recorded. The tax effects for these provisional items are recorded as discrete adjustments to the income tax provision as information becomes known. The components of the provisional net income taxes recorded in 2017 and through the nine-month period ended September 30, 2018 are based on the best available information at the current time. As noted, guidance and interpretations have been issued throughout 2018 and more is expected to be released in future periods. Provisional items include amounts related to the mandatory repatriation of undistributed international earnings, certain foreign exchange gains or losses, foreign tax credits as well as the impacts on deferred taxes, for example 100% expensing of qualified assets. Based on additional guidance issued during the applicable periods related to the computation of the Transition Tax, the Company recorded additional provisional tax expense of $1.8 million in the first quarter of 2018 and a provisional tax benefit of $800 in the third quarter of 2018. In the second quarter of 2018, the Company reclassified its provisional liability associated with the Transition Tax from a long-term liability to a current obligation, offsetting its prepaid income tax balance, as a result of guidance issued by the IRS during that quarter. The Company's consolidated effective income tax rate was 21.8% and 26.1%, respectively, for the three and nine-month periods ended September 30, 2018, as compared to 36.7% and 37.1% for the comparable periods in 2017. In addition to the lower U.S. federal tax rate that resulted from the 2017 Tax Act, the effective tax rate in 2018 benefited from significant share-based compensation deductions principally as a result of stock option exercises occurring during the second quarter of 2018, required discrete adjustments as a result of interpretations issued related to the 2017 Tax Act that included the recording of certain foreign tax credits earned as a result of withholding taxes paid on repatriated foreign earnings that totaled $7 million and a state income tax refund of $4 million settled during the third quarter of 2018. These amounts were partially offset by certain expenses that are no longer deductible under the 2017 Tax Act. As discussed above, some elements of the recorded impacts of the 2017 Tax Act remain provisional as of September 30, 2018. The final amounts of provisional as well as other recorded income tax amounts may differ, possibly materially, due to, among other things, changes in estimates, interpretations and assumptions the Company has made, changes in IRS or Treasury interpretations, the issuance of new guidance, legislative actions, changes in accounting standards or related interpretations in response to the 2017 Tax Act and future actions by states within the United States that have not currently adopted the 2017 Tax Act. For further information and discussion of the potential impact of the 2017 Tax Act, refer to “Item 1A.
