Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The tax provision for interim periods is determined using the estimated annual effective consolidated tax rate, based on the current estimate of full-year earnings before taxes, adjusted for the impact of discrete quarterly items. The provision for income taxes was $15.0 million and $16.1 million for the three months ended March 31, 2020 and 2019, respectively, and the effective tax rate was 17.4% and 23.1%, respectively. The decrease in the effective tax rate is primarily due to an increase in stock-based compensation deductions for the three months ended March 31, 2020 as compared to the same period in 2019.
