Product Warranties Disclosures [Abstract] |
Warranty Accrual | Warranty Accrual The Company provides an assurance type warranty against all substantial defects in material and workmanship. The standard warranty offered on products sold after January 1, 2017 was modified to provide specific warranty periods by product component, with no warranty period longer than ten years. The Company’s warranty is not a guarantee of service life, which depends upon events outside the Company’s control and may be different from the warranty period. The Company accrues an estimate of its exposure to warranty claims based upon both product sales data and an analysis of actual warranty claims incurred. The following is a summary of the Company’s warranty-claim activity for the three months ended April 30, 2021 and 2020:
