Income Tax Disclosure [Abstract]  
Income Taxes Income TaxesFor interim tax reporting we estimate our annual effective tax rate and apply it to our year to date income before income taxes. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and the effect of changes in tax laws or rates, are reported in the interim period in which they occur, if applicable.  Income tax (benefit) expense for the three and six months ended June 30, 2020 was $(1.1) million and $(1.4) million, respectively, compared to $(0.4) million and $(0.3) million for the three and six months ended June 30, 2019, respectively. During the three and six months ended June 30, 2020, the effective tax rates were 20% and 20%, respectively. The differences between the effective tax rates and the statutory rate of 21.0% were primarily due to benefit of tax credits in the U.S. partially offset by earnings generated in Mexico and Canada, which both have higher statutory income tax rates than the U.S., and U.S. taxation of foreign earnings under the Global Intangible Low-Taxed Income (GILTI) provisions.
