Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES In the first quarter of 2017, we recorded tax expense of $70 million on income before income taxes of $239 million. Income tax expense for the three months ended March 31, 2017 was favorably impacted by $2 million of various discrete tax adjustments. In the first quarter of 2016, we recorded tax expense of $78 million on income before income taxes of $267 million. Income tax expense for the three months ended March 31, 2016 was favorably impacted by $12 million, comprised of a $7 million tax benefit related to the release of a valuation allowance in Brazil due to the collection of a receivable that had previously been written off as uncollectible and $5 million of tax benefits related to various other discrete tax adjustments. We record taxes based on overall estimated annual effective tax rates. The difference between our effective tax rate and the U.S. statutory rate was primarily attributable to the discrete items noted above and an overall lower effective tax rate in the foreign jurisdictions in which we operate. Our losses in various foreign taxing jurisdictions in recent periods represented sufficient negative evidence to require us to maintain a full valuation allowance against certain of our net foreign deferred tax assets. Each reporting period we assess available positive and negative evidence and estimate if sufficient future taxable income will be generated to utilize these existing deferred tax assets. We do not believe that sufficient positive evidence required to release all or a significant portion of these valuation allowances will exist within the next twelve months. At January 1, 2017, we had unrecognized tax benefits of $63 million that if recognized, would have a favorable impact on our tax expense of $47 million. We had accrued interest of $4 million as of January 1, 2017. If not favorably settled, $12 million of the unrecognized tax benefits and all of the accrued interest would require the use of our cash. We do not expect any changes to our unrecognized tax benefits during 2017 to have a significant impact on our financial position or results of operations. Generally, years from 2011 onward are still open to examination by foreign taxing authorities. We are open to examination in Germany from 2011 onward and in the United States for 2016.
