The Company's effective income tax rate was lower in 2018 due primarily to the impact of the 2017 Tax Cuts and Jobs Act (2017 Tax Act) that was enacted in December of 2017. The 2017 Tax Act included broad and complex changes to the U.S. tax code including a reduction of the corporate income tax rate from 35% to 21%, the move toward a territorial tax system and the elimination of the domestic manufacturing deduction. During the three months ended December 31, 2017, the Company recorded a $53.1 million tax expense to recognize the initial effects of the 2017 Tax Act relating primarily to the remeasurement of deferred tax assets.
