Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense of $3.9 and $4.9 for the three months ended June 30, 2020 and 2019, respectively, represents taxes on both U.S. and foreign earnings at a combined effective income tax rate of 15.7% and 25.1%, respectively. Income tax expense of $5.6 and $2.9 for the six months ended June 30, 2020 and 2019, respectively, represents taxes on both U.S. and foreign earnings at a combined effective income tax rate of 16.0% and 15.7%, respectively. The effective income tax rate of 15.7% and 16.0% for the three and six months ended June 30, 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 foreign operations for which no benefit was recorded. We expect our 2020 full year effective income tax rate to be approximately 19%. The effective income tax rate of 25.1% and 15.7% for the three and six months ended June 30, 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. As of June 30, 2020 and December 31, 2019, we had a liability for gross unrecognized tax benefits of $2.6 and $2.4, respectively. This amount includes $1.8 of unrecognized tax benefits as of both June 30, 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.
