13.	Income Taxes

The Company’s effective tax rates for the three months ended March 31, 2016 and 2015 were (17.4)% and (34.9)%, respectively. The Company’s effective tax rates for the six months ended March 31, 2016 and 2015 were (21.1)% and (35.2)%, respectively. The United States statutory tax rate for the same periods was 35%. The lower effective tax rates resulted from (i) the provision of a valuation allowance against the Company’s Canadian subsidiary’s deferred tax assets of $0.5 million and $2.5 million, respectively, for the three months and six months ended March 31, 2016, to fully offset the value of its deferred tax assets, and (ii) a net adjustment totaling $1.2 million and $1.0 million, respectively, for the three months and six months ended March 31, 2016 to correct the Company’s fiscal year 2015 income tax benefit. The Company has concluded that the tax correction was immaterial to its fiscal year 2015 financial statements and, therefore, such adjustments were reported in the Company’s financial statements for each of the periods ended March 31, 2016.
