Income Tax Disclosure [Abstract]  
INCOME TAXES INCOME TAXES For interim tax reporting, we estimate one single effective tax rate for tax jurisdictions not subject to a valuation allowance, which is applied to the year-to-date ordinary income/(loss). Tax effects of significant unusual or infrequently occurring items are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur.Based on all available evidence, we established a valuation allowance against certain net operating losses and tax credits of $1 billion during the first nine months of 2020, as it is more likely than not that these deferred tax assets will not be realized. In assessing the realizability of deferred tax assets, we consider the trade-offs between cash preservation and cash outlays to preserve tax credits
