Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense of $1.7 for the three months ended March 31, 2020 and income tax benefit of $2.0 for the three months ended March 31, 2019, represents taxes on both U.S. and foreign earnings at a combined effective income tax rate of 16.7% and 200.0%, respectively. The effective income tax rate of 16.7% for the three months ended March 31, 2020 differed from the U.S. federal statutory rate of 21% primarily due to excess tax benefits associated with stock compensation, partially offset by the effect of income earned by certain of our foreign entities being taxed at higher rates than the U.S. federal statutory rate and losses incurred by certain of our Chinese operations for which no benefit was recorded. We expect our 2020 full year effective income tax rate to be approximately 20%. As of March 31, 2020 and December 31, 2019, we had a liability for gross unrecognized tax benefits of $2.5 and $2.4, respectively. This amount includes $1.8 of unrecognized tax benefits as of both March 31, 2020 and December 31, 2019, 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.
