Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Contracts	Derivative ContractsWe generate revenues and incur expenses in numerous currencies and are exposed to foreign currency risk. In the first quarter of fiscal year 2021, we implemented a currency risk management program, executing foreign currency forward contracts to offset the gains and losses on foreign currency denominated monetary assets and liabilities. The duration of our forward contracts are less than 12 months. We do not enter into any derivatives for trading or speculative purposes.During the three months ended April 30, 2020, we recorded a loss of $0.5 million in other income (expense), net within our condensed consolidated statements of operations and is reported as part of other adjustments to reconcile net loss to net cash provided by operating activities in the condensed consolidated statements of cash flows. As of April 30, 2020, we had outstanding foreign currency forward contracts not designated as hedges with a total notional value of $12.3 million. The fair value of these outstanding derivative contracts was not material.
