Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The Company’s effective tax rate for the nine months ended September 30, 2018 is a provision of 42.4%. Such rate differed from the Federal statutory rate of 21.0% primarily due to an adjustment of the one-time transition tax on the deemed repatriation of cumulative foreign subsidiary earnings initially recorded during the three months ended December 31, 2017 and taxes on the Company’s international operations. The Company’s effective tax rate for the nine months ended September 30, 2017 was a provision of 32.9%. Such rate differed from the Federal statutory rate of 35.0% primarily due to foreign taxes as a result of the mix of the Company’s earnings between the U.S. and foreign jurisdictions. In December 2017, the Tax Act made substantial changes to corporate income tax laws. The Company is recognizing the effects of the Tax Act in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of FASB Accounting Standards Codification Topic 740, Income Taxes, in the reporting period that the Tax Act was signed into law. During the three months ended December 31, 2017 the Company had recorded a provisional income tax benefit of $317 million related to the remeasurement of its net deferred income tax liabilities as a result of the reduced corporate tax rate and a provisional tax expense of $104 million for the one-time transition tax on the deemed repatriation of cumulative foreign subsidiary earnings. During the three months ended September 30, 2018, the Company revised the provisional expense of $104 million and recorded an additional tax expense of $30 million resulting from revised estimated calculations of historical earnings of foreign subsidiaries. During the fourth quarter of 2018, the Company will finalize the accounting for the effects of the Tax Act. Additional information needed to finalize the provisional tax benefit on the remeasurement of net deferred income tax liabilities include calculations and analysis of the repeal of the like-kind exchange provisions and calculations of effective corporate state income tax rates based on the filing of the Company’s 2017 U.S. corporate income tax returns during the fourth quarter of 2018. The provisional tax expense for the one-time transition tax on cumulative foreign earnings will be finalized based on the analysis of state tax laws and guidance on the transition tax. In addition, the Company continues to evaluate whether or not to continue to assert indefinite reinvestment on a part or all of its undistributed foreign earnings. This requires the Company to analyze its global working capital and cash requirements in light of the Tax Act and the potential tax liabilities attributable to a repatriation to the U.S., such as foreign withholding taxes and U.S. tax on currency transaction gains or losses. The Company did not record any deferred taxes attributable to its investments in its foreign subsidiaries. The Company will record the tax effects of any change in its assertion during the fourth quarter of 2018.
