8. INCOME TAXES

The Company's effective tax rate was (1)% and 86% for the three months ended September 30, 2018 and 2017, respectively. The effective tax rate is calculated by dividing the income tax provision by net income (loss) before income tax expense. The difference in the effective tax rate and the U.S. federal statutory rate was due primarily to the change in pretax profitability, and geographic mix of profits and losses and the full valuation allowance recorded during the third quarter of fiscal year 2018.
