Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesIncome tax expense was $1.2 million and $0.1 million for the three months ended July 31, 2019 and 2018, respectively, and $1.5 million and $0.2 million for the six months ended July 31, 2019 and 2018, respectively. Income tax expense for the three and six months ended July 31, 2019 are related to foreign income taxes and state taxes. Based on the available objective evidence during the three and six months ended July 31, 2019, we believe it is more likely than not that the tax benefits of the U.S. losses incurred may not be realized. Accordingly, we recorded a full valuation allowance against the tax benefits of the U.S. losses incurred.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
