Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our provision for income tax primarily reflects taxes on international operations and state income taxes. The difference between the income tax provision that would be derived by applying the statutory rate to our loss before income taxes and the income tax provision recorded was primarily attributable to changes in our valuation allowance, stock-based compensation expense and research and development credits. At the end of the third quarter of fiscal 2021, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for fiscal 2020.

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.
