Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. With few exceptions, the Company is no longer subject to state and foreign income tax examinations by tax authorities for years before 2015. The United States Internal Revenue Service has completed examinations of the Company’s U.S. federal income tax returns through 2016. As of January 31, 2021, gross unrecognized tax benefits were $18.6 million and accrued interest and penalties on these unrecognized tax benefits were $2.4 million. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income taxes on the Condensed Consolidated Statements of Earnings. The Company estimates that within the next 12 months it is reasonably possible that its uncertain tax positions could decrease by as much as $5.4 million due to lapses in statutes of limitation. The statutes of limitation periods for the Company’s various tax jurisdictions range from two years to ten years. The Company believes it is remote that any adjustment necessary to the reserve for income taxes over the next 12 months will be material. However, it is possible the ultimate resolution of audits or disputes may result in a material change to the Company’s reserve for income taxes, although the quantification of such potential adjustments cannot be made at this time.
