INCOME TAXES

For interim income tax reporting the Company estimates its annual effective tax rate and applies this effective tax rate to its year to date pre-tax (loss) income.  For the nine months ended September 30, 2015, the effective tax rate differed from the statutory rate primarily as a result of the U.S. and Canadian valuation allowances and the impact of the statutory rate change in Alberta, Canada. For the nine months ended September 30, 2014, the effective tax rate differed from the statutory rate primarily due to the U.S. valuation allowance and foreign operations.
