Income Taxes
The Company incurred a pretax loss in each of the three months ended March 31, 2018 and 2017, which consists entirely of loss in the U.S. and resulted in no provision for income tax expense during the periods then ended. The effective tax rate is 0% in each of the three months ended March 31, 2018 and 2017 because the Company has generated tax losses and has provided a full valuation allowance against its deferred tax assets.
