The Company’s effective tax rates for the six months ended March 31, 2017 and 2016 were (3.4)% and (21.1)%, respectively. The United States statutory tax rate for the same periods was 35%. Compared to the United States statutory rate, the lower effective tax rates for the three and six months ended March 31, 2016 resulted primarily from a valuation allowance against the Company’s Canadian subsidiary’s net deferred tax assets. The lower effective tax rates for the three and six months ended March 31, 2017 primarily resulted from the Company’s inability to recognize deferred tax assets and other tax benefits in connection with the losses it incurred in the United States and Canada due to the uncertainty surrounding the Company’s ability to utilize such deferred tax assets in the future to offset taxable income.
