Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's provision for income taxes is based upon an estimated annual tax rate for the year applied to federal, state and foreign income. On a quarterly basis, the annual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. The Company's effective tax rate for the six months ended June 30, 2020 was 44.6%. This rate was unfavorably impacted by $94 million of restructuring expenses and merger, acquisition and divestiture expenses that were largely non-deductible for tax purposes, resulting in only $9 million of tax benefit being recognized. This rate was further unfavorably impacted by $26 million of asset impairment costs for which no tax benefit was recognized as full valuation allowances were recorded against the corresponding deferred tax assets. The Company also recorded reductions in income tax expense of $10 million for other one-time adjustments primarily related to tax law changes in India that were enacted during the first three months of 2020 and the release of certain unrecognized tax benefits due to the closure of an audit. The Company's effective tax rate for three months ended June 30, 2020 was 6.0%. The rate includes restructuring expenses, merger, acquisition and divestiture expenses, and asset impairment costs that are largely non-deductible for tax purposes. During the three months ended June 30, 2020, the Company recorded $75 million of such expenses for which only a $5 million tax benefit was recognized. The Company's effective tax rate for the six months ended June 30, 2019 was 31.7%. This rate includes reductions of income tax expense of $7 million related to restructuring expense, $6 million related to other postretirement expense, and $5 million for other one-time tax adjustments. This rate also includes an increase in income tax expense of $22 million due to the U.S. Department of the Treasury's issuance of the final regulations during the first three months of 2019 related to the calculation of the one-time transition tax associated with the Tax Cuts and Jobs Act of 2017. The annual effective tax rates differ from the U.S. statutory rate primarily due to foreign rates which differ from those in the U.S., U.S. taxes on foreign earnings, the realization of certain business tax credits, including foreign tax credits, and favorable permanent differences between book and tax treatment for certain items, including equity in affiliates' earnings.
