Income Taxes

Our effective tax rates were 27.5% and 26.1% for the three and nine months ended September 30, 2019, respectively, and 19.0% and 23.5% for the three and nine months ended September 30, 2018, respectively. Our effective tax rates differ from the U.S. statutory rate of 21.0% due to the impacts of state income taxes, the incremental tax on profits of branches taxed in both U.S. and foreign jurisdictions, excess tax benefits of equity based compensation, tax return true-ups, and non-deductible executive compensation.

Our federal tax years remain open under statute from 2014 forward. The 2014-2017 tax years have been reviewed by the Internal Revenue Service but remain open due to tax loss carryback claims that have been filed. We have state tax returns that are under audit in the normal course of business, and our Mexican subsidiaries' tax return statutes remain open from 2013 forward. We believe we are appropriately reserved for any potential matters.

During the nine months ended September 30, 2019, we effectively settled a state tax audit resulting in a decrease in uncertain tax positions of $5.7 million.
