Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate was (9.8)% and (12.5)% for the three months and six months ended June 30, 2019, respectively, and 19.1% and 18.2% for the three months and six months ended June 30, 2018, respectively. Our 2019 effective tax rate differs from the U.S. federal statutory tax rate of 21% principally due to a discrete tax charge of $6.0 million related to final tax regulations published by the Department of the Treasury and Internal Revenue Service on February 4, 2019. The 2019 effective tax rate was also impacted by the minimum tax on global intangible low-tax income (“GILTI”) and earnings outside the United States, which are taxed at different rates than the U.S. federal statutory tax rate of 21%. The effective tax rate for the three months ended June 30, 2019, was primarily impacted by changes in the full year forecast book income (loss) within each jurisdiction in which the Company operates. Our 2018 effective tax rate differed from the U.S. federal statutory tax rate of 21% due to permanent differences including GILTI and earnings outside the United States, which were taxed at different rates than the U.S. federal statutory rate of 21%.
