Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, we update our estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, we make a cumulative adjustment in such period. Our quarterly tax provision, and estimate of our annual effective tax rate, is subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income relates, changes in how we do business, and tax law developments. Our estimated annual effective tax rate for the year differs from the U.S. statutory rate of 21% as a result of our U.S. losses for which no benefit will be realized, as well as our foreign operations which are subject to tax rates that differ from those in the U.S. We recorded a provision for income taxes of $0.7 million and $0.5 million for the three months ended January 31, 2020 and 2019, respectively, and $1.5 million and $0.9 million for the six months ended January 31, 2020 and 2019, respectively. We are subject to income tax in the U.S. as well as other tax jurisdictions in which we conduct business. Earnings from our non-U.S. operations are subject to income taxes in the countries in which we operate. Our provision for income taxes consists primarily of both income and withholding taxes in the foreign jurisdictions in which we conduct business. The realization of deferred tax assets is dependent upon the generation of sufficient taxable income of the appropriate character in future periods. We assess our ability to realize the deferred tax assets on a quarterly basis and we establish a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized. We weigh all available positive and negative evidence, including our earnings history and results of recent operations, scheduled reversals of deferred tax liabilities, projected future taxable income and tax planning strategies. Due to the weight of objectively verifiable negative evidence, including our history of losses in certain jurisdictions, we believe that it is more likely than not that our U.S. federal, state, and U.K. deferred tax assets will not be realized. Accordingly, we have maintained a valuation allowance on our U.S. federal, state, and U.K. deferred tax assets.
