Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES In the second quarter of 2016, we recorded tax expense of $93 million on income before income taxes of $301 million. For the first six months of 2016, we recorded tax expense of $171 million on income before income taxes of $568 million. Income tax expense for the three months ended June 30, 2016 was unfavorably impacted by $3 million of various discrete tax adjustments. Income tax expense for the six months ended June 30, 2016 was favorably impacted by $9 million, primarily related to a $7 million tax benefit resulting from the release of a valuation allowance in our Americas operations and $2 million of net tax benefits related to various discrete tax adjustments. In the second quarter of 2015, we recorded tax expense of $120 million on income before income taxes of $328 million. For the first six months of 2015, we recorded tax expense of $243 million on income before income taxes of $687 million. Income tax expense for the three months ended June 30, 2015 was unfavorably impacted by $3 million of discrete tax adjustments, primarily related to the establishment a valuation allowance in EMEA. Income tax expense for the six months ended June 30, 2015 was unfavorably impacted by $8 million of discrete tax adjustments, primarily related to an audit of prior tax years and the establishment of a valuation allowance, both in EMEA. We record taxes based on overall estimated annual effective tax rates. In 2016, the reduction of our effective tax rate compared to the U.S. statutory rate was primarily attributable to income in various foreign taxing jurisdictions where we maintain a full valuation allowance on certain deferred tax assets. 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. However, it is reasonably possible that sufficient positive evidence required to release all, or a portion, of certain valuation allowances, primarily in EMEA, will exist during 2016. This may result in a reduction of the valuation allowance by up to $255 million. At January 1, 2016, we had unrecognized tax benefits of $54 million that if recognized, would have a favorable impact on our tax expense of $40 million. We had accrued interest of $5 million as of January 1, 2016. If not favorably settled, $9 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 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 2015.
