Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax (benefit) expense from continuing operations of $(2.0) and $1.6 for the three months ended March 31, 2019 and 2018, respectively, represents taxes on both U.S. and foreign earnings at a combined effective income tax rate of 200.0% and 25.4%, respectively. The effective income tax rate of 200% for the three months ended March 31, 2019 differed from the U.S. federal statutory rate of 21% primarily due to excess tax benefits associated with stock compensation and the effect of income earned by certain of our foreign entities being taxed at higher rates than the U.S. federal statutory rate, partially offset by losses incurred by certain of our Chinese operations for which no benefit was recorded. The effective income tax rate of 25.4% for the three months ended March 31, 2018, differed from the U.S. federal statutory rate of 21% primarily due to the effect of income earned by certain of the Company’s foreign entities being taxed at higher rates than the U.S. federal statutory rate as well as losses incurred by certain of our Chinese operations for which no benefit was recorded. As of March 31, 2019 and December 31, 2018, we had a liability for gross unrecognized tax benefits of $2.4 and $2.3, respectively. This amount includes $1.8 and $0.1 of unrecognized tax benefits as of March 31, 2019 and December 31, 2018, respectively, which, if ultimately recognized, would reduce our annual effective income tax rate. We recognize interest and penalties related to uncertain tax positions in income tax expense. These amounts were not significant for the periods presented.
