Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Our effective tax rates were 27.3% and 25.1% for the three and six months ended June 30, 2019, respectively, and 25.1% and 25.7% for the three and six months ended June 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, income attributable to the noncontrolling interests in partially-owned leasing subsidiaries for which no income tax expense is provided, the incremental tax on profits of branches taxed in both U.S. and foreign jurisdictions, excess tax benefits of equity based compensation, non-deductible executive compensation, and tax return true-ups.

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 remain open from 2013 forward. We believe we are appropriately reserved for any potential matters.

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