Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes At the end of each interim period, we estimate our annual effective tax rate and apply that rate to our interim earnings. We also record the tax impact of certain unusual or infrequently occurring items, including changes in judgment about valuation allowances and the effects of changes in tax laws or rates, in the interim period in which they occur. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in state and foreign jurisdictions, permanent and temporary differences between book and taxable income, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or as the tax environment changes. Our effective income tax rate for the six months ended June 30, 2020 was 27.7%, compared to 27.1% for the comparable prior year period. The increase is attributable to a higher expected annual effective tax rate in 2020 as a result of the estimated unfavorable impact of the COVID-19 pandemic on the Company’s results of operations. The primary factor in the increase is the impact of lower available interest deductions in certain foreign jurisdictions due to legislative thin capitalization constraints, typically based on profitability. For the six months ended June 30, 2020, the effective tax rate was reduced 0.3% by favorable discrete items, primarily excess tax benefits on stock-based compensation and deferred tax adjustments as a result of statutory tax rate changes. Net discrete items for the six months ended June 30, 2019 added 0.1% to the effective tax rate. Ongoing uncertainties due to the impact of the COVID-19 pandemic on the Company’s operations for the remainder of 2020 may result in volatile effective tax rates driven generally by the level of profitability and changes in the mix of earnings across the Company’s jurisdictions.
