Income tax expense for the six months ended June 30, 2018 was reduced by $12.1 million of tax benefits recognized related to changes to provisional amounts previously recognized for the impact of the 2017 Tax Cuts and Jobs Act (“Tax Act”), and $6.0 million of excess tax benefits related to stock-based compensation.
