Our second quarter and year to date effective tax rate was higher than prior year primarily due to the unfavorable impact of lapping a prior year decrease to the provisional tax expense recorded in the fourth quarter of 2017 associated with the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), the unfavorable impact of the global intangible low-taxed income provisions of the Tax Act in the current year, and lapping the favorable impact attributable to prior year refranchising transactions. These items were partially offset by lapping $19 million in expense recorded in the prior year to correct an error associated with the tax recorded on a prior year divestiture.
