Income Taxes Income Taxes
For 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 months ended March 31, 2020 was $(0.3) million, compared to $0.04 million for the three months ended March 31, 2019.
During the three months ended March 31, 2020 , the differences between the actual effective tax rate of 22.2% and the statutory rate of 21.0% was primarily due to benefit of tax crredits 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.
