Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and six months ended August 31, 2017, we recorded an income tax provision of $0.4 million and $2.9 million, respectively. For the three and six months ended August 31, 2016, we recorded an income tax provision of $5.2 million and $8.5 million, respectively. We maintain a valuation allowance against a significant portion of our deferred tax assets, including U.S. federal and state deferred tax assets and certain foreign deferred tax assets, because realization of these tax benefits through future taxable income did not meet the more-likely-than-not threshold. We intend to maintain the valuation allowance until sufficient positive evidence exists to support its reversal. The difference between the income tax provision that would be derived by applying the statutory rate to our before tax income for the three and six months ended August 31, 2017 and the income tax provision actually recorded is primarily due to the temporary differences we do not expect to benefit from due to our valuation allowance, as well as non-deductible stock-based compensation expense and other currently non-deductible items.
