Income Tax Disclosure [Abstract]  
Income Tax Income TaxOur effective tax rate may vary from the U.S. federal statutory tax rate due to the change in the mix of earnings in various state jurisdictions with different statutory rates, benefits related to tax credits, and the tax impact of non-deductible expenses, stock award activities and other permanent differences between income before income taxes and taxable income. The effective tax rate for the three and six months ended June 30, 2019 was 20.0% and 20.9%, respectively. The variance from the U.S. federal statutory tax rate of 21% for the three months ended June 30, 2019 was primarily attributable to the mix of earnings in jurisdictions with lower statutory tax rates than the U.S.. The effective tax rate for the three and six months ended June 30, 2018 was 23.5% and 21.5%, respectively. The variance from the U.S. federal statutory tax rate of 21% for the three months ended June 30, 2018 was primarily attributable to tax deductions related to stock award activities which were recorded as discrete items in the quarter.
