Payables and Accruals [Abstract]
Restructuring Charges	Restructuring Charges In the third quarter of fiscal 2021, we initiated a restructuring plan for involuntary and voluntary employee termination and facility closure actions as part of a business reorganization (the 2021 Plan). The 2021 Plan was substantially completed in the first quarter of fiscal 2022 and the total charges under the 2021 Plan were $45.5 million. During the three months ended July 31, 2022, we made payments of $0.9 million under the 2021 Plan. As of July 31, 2022, the outstanding restructuring related liabilities were immaterial and recorded in accounts payable and accrued liabilities in the unaudited condensed consolidated balance sheets.
