The second quarter and first six months 2017 effective tax rates include a $22 million tax benefit to reflect finalization of prior years' income tax returns. The first six months 2017 effective tax rate also reflects a $22 million tax benefit due to planned amendments to prior years' income tax returns. The second quarter and first six months 2016 effective tax rates include a $16 million one-time benefit for the restoration of tax basis for which depreciation deductions were previously limited. The first six months 2016 effective tax rate also reflects a $9 million tax benefit primarily due to adjustments to the tax provision to reflect the finalization of 2014 foreign income tax returns.
