Income Tax Disclosure [Abstract] |
Income Tax Disclosure | 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 made changes to the U.S. tax code, which included (1) reduced U.S. corporate tax rate from 35 percent to 21 percent, (2) implemented a base erosion and anti-abuse tax, (3) generally eliminated U.S. federal income taxes on dividends from foreign subsidiaries, (4) a new provision designed to tax global intangible low-taxed income ("GILTI") of foreign subsidiaries which allows for the possibility of utilizing foreign tax credits to offset the tax liability (subject to some limitations), (5) a lower effective U.S. tax rate on certain revenues from sources outside the U.S., and (6) a one-time transition tax on certain undistributed earnings of foreign subsidiaries. In the period ended December 31, 2017, we recorded a provisional discrete net tax benefit associated with the Tax Act and related matters. In the quarter ended March 31, 2018, we recorded discrete net tax expense of $82 primarily related to recently issued guidance affecting tax benefits we recorded in fourth quarter 2017 for certain tax planning actions taken in anticipation of the Tax Act. As of March 31, 2018, the amounts recorded for the Tax Act remain provisional for the transition tax, the remeasurement of deferred taxes, and our reassessment of permanently reinvested earnings, uncertain tax positions and valuation allowances. These estimates may be impacted by further analysis and future clarification and guidance regarding available tax accounting methods and elections, earnings and profits computations, state tax conformity to federal tax changes and the impact of the GILTI provisions. At March 31, 2018, we were not able to reasonably estimate, and therefore have not recorded, deferred taxes for the GILTI provisions. We have not yet determined our policy election with respect to whether to record deferred taxes for basis differences expected to reverse as a result of the GILTI provisions in future periods or use the period cost method. We have, however, included an estimate of the current GILTI impact in our tax provision for 2018.
