Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The company had an effective tax rate of 18.3% and 26.9% on losses before tax for the three months ended March 31, 2017 and March 31, 2016, respectively, compared to an expected benefit at the U.S. statutory rate of 35% on the pre-tax losses for each period. The company's effective tax rate for the three months ended March 31, 2017 and March 31, 2016 was unfavorable as compared to the U.S. federal statutory rate expected benefit, principally due to the negative impact of the company not being able to record tax benefits related to the significant losses in countries which had tax valuation allowances. The effective tax rate was reduced by certain taxes outside the United States, excluding countries with tax valuation allowances, that were at an effective rate lower than the U.S. statutory rate. During 2016, installment payments were made in the first quarter related to a previously disclosed liability for uncertain tax positions, and subsequent to the end of the first quarter, the company accelerated and paid the balance of the installment obligation, in order to reduce interest costs.
