Income Taxes	Income Taxes Our effective tax rate was 17.9% and (5.2)% for the three months and nine months ended September 30, 2019, respectively. Our effective tax rate was 28.4% and 20.8% for the three months and nine months ended September 30, 2018, respectively. Our effective tax rate for the nine months ended September 30, 2019, differs from the U.S. federal statutory tax rate of 21% principally due to a discrete tax charge of $6.0 million related to final tax regulations published by the Department of the Treasury and Internal Revenue Service on February 4, 2019, as well as the minimum tax on global intangible low-tax income (“GILTI”). The effective tax rate for the three months ended September 30, 2019, is impacted by the minimum tax on GILTI. Our 2018 effective tax rate differed from the U.S. federal statutory tax rate of 21% due to permanent differences including GILTI and earnings outside the United States, which were taxed at different rates than the U.S. federal statutory rate of 21%.
