8. Income Taxes

The Company’s quarterly provision for income taxes is calculated using an estimated annual effective tax rate for the period, adjusted for discrete items that occurred within the period presented. The consolidated income tax provision attributable to the Company was a $0.9 million expense for the three months ended September 30, 2016 and a $1.8 million expense for the three months ended September 30, 2015, primarily relating to taxable Canadian helicopter operations. These amounts represent an effective tax rate of (2.2)% and (4.1)% for the three months ended September 30, 2016 and 2015, respectively. The federal blended statutory rate for the three months ended September 30, 2016 and 2015 was 33.3% and 32.9%, respectively. The effective tax rates for the periods presented differ from the federal blended statutory rates due to changes in the recorded valuation allowances for entities in the United States and Canada.
