Income Tax Disclosure [Abstract]
Income Taxes	Note 14. Income Taxes On December 22, 2017, the United States enacted tax reform legislation that included a broad range of business tax provisions, including a reduction in the U.S. federal tax rate from 35% to 21%. In addition to the tax rate reduction, the legislation establishes new provisions that affect our 2018 results, including but not limited to, the creation of a new minimum tax called the base erosion anti-abuse tax (BEAT); a new provision that taxes U.S. allocated expenses (e.g. interest and general administrative expenses) as well as currently taxes certain income from foreign operations (Global Intangible Low-Tax Income, or “GILTI”); a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; a new limitation on deductible interest expense; the repeal of the domestic manufacturing deduction; and limitations on the deductibility of certain employee compensation. Further tax legislative guidance is expected before 2018 year-end. Certain impacts of the new legislation would have generally required accounting to be completed in the period of enactment, however in response to the complexities of this new legislation, the SEC issued guidance to provide companies with relief. The SEC provided up to a one-year window for companies to finalize the accounting for the impacts of this new legislation and we anticipate finalizing our accounting during 2018. While our accounting for the enactment of the new U.S. tax legislation is not complete, during the three months ended September 30, 2018, we recorded an $8 million U.S. tax reform discrete net tax expense, consisting of a $3 million increase in our transition tax liability and $5 million of costs from other provisional tax reform updates. During the nine months ended September 30, 2018, we recorded $95 million in discrete net tax costs primarily comprised of an increase to our transition tax liability of $89 million as a result of additional guidance issued by the Internal Revenue Service and various state taxing authorities, new state legislation enacted during the period and further refinement of various components of the underlying calculations. Based on current tax laws, our estimated annual effective tax rate for 2018, excluding discrete tax impacts, is 22.0%, reflecting favorable impacts from the mix of pre-tax income in various non-U.S. jurisdictions and the reduction in the U.S. federal tax rate, partially offset by unfavorable provisions within the new U.S. tax reform legislation. Our 2018 third quarter effective tax rate of 46.3% was unusually high due to $184 million of deferred tax expense related to the $757 million gain on the KDP transaction reported as a gain on equity method transaction. Excluding this impact, our third quarter effective tax rate was 18.6%, which was favorably impacted by discrete net tax benefits of $19 million, primarily related to a $26 million benefit from the release of liabilities for uncertain tax positions due to expirations of statutes of limitations and audit settlements in several jurisdictions. Our effective tax rate for the nine months ended September 30, 2018 was 31.9% and was also unusually high as a result of the KDP transaction. Excluding this impact, our effective tax rate for the nine months was 23.0%, which was unfavorably impacted by $22 million of net tax expense from discrete one-time events. The discrete net tax expense primarily consisted of $89 million of additional transition tax liability recognized as an adjustment to the prior provisional estimate, partially offset by a $70 million benefit from the release of liabilities for uncertain tax positions due to expirations of statutes of limitations and audit settlements in various jurisdictions. As of the end of the third quarter of 2017, our estimated annual effective tax rate for 2017, excluding the impacts from the sale of our Australian grocery business, was 25.8%, reflecting favorable impacts from the mix of pre-tax income in various non-U.S. tax jurisdictions, partially offset by an increase in domestic earnings. Our 2017 third quarter effective tax rate of 23.4% was favorably impacted by the divestiture of our Australian grocery business, which had a lower effective tax rate, resulting in a $27 million tax expense related to the pre-tax gain of $187 million. Our effective tax rate for the nine months ended September 30, 2017 was 21.3% and was favorably impacted by the sale of our Australian grocery business as well as other discrete one-time benefits. The discrete net tax benefits primarily consisted of a $74 million benefit from the release of liabilities for uncertain tax positions due to expirations of statutes of limitations and audit settlements in various jurisdictions and a $16 million benefit relating to the U.S. domestic production activities deduction.
