The difference between the U.S. federal statutory income tax rate and our effective income tax rate for the three-months ended March 31, 2019 was impacted by a variety of factors, primarily stemming from the location in which income was earned and discrete net tax expenses primarily related to uncertain tax positions. The difference between the U.S. federal statutory income tax rate and our effective income tax rate for the three-months ended March 31, 2018 was impacted by a variety of factors, primarily stemming from discrete tax benefits related to adjustments recorded for the U.S. Tax Cuts and Jobs Act (“TCJA”) and excess tax benefits realized from stock-based compensation arrangements.
