Accounting Policies [Abstract]
Use of Estimates	Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and may result in material effects on the Company’s operating results and financial position. In addition, the Company has considered the potential impact of the COVID-19 pandemic on the business operations. Although no impairment or other effects have been identified to date related to the COVID-19 pandemic, there is substantial uncertainty in the nature and degree of its continued effects over time. This uncertainty affects management’s accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions as additional events and information are known.
Principles of Consolidation	Principles of Consolidation. The unaudited condensed consolidated financial statements include the accounts of the Company and all of its subsidiaries. All intercompany accounts and transactions have been eliminated.
Fiscal Year End	Fiscal Year End. The Company’s fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, the Company has a 53-week year. When a 53-week year occurs, the Company includes the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2021 and 2020 are both 52-week years. Fiscal 2021 will end on October 30, 2021. Fiscal 2020 ended on October 31, 2020. For presentation purposes, the unaudited condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.
