Snap-on provides product warranties for specific product lines and accrues for estimated future warranty cost in the period in which the sale is recorded. Snap-on calculates its accrual requirements based on historic warranty loss experience that is periodically adjusted for recent actual experience, including the timing of claims during the warranty period and actual costs incurred. Snap-on’s product warranty accrual activity for 2022, 2021 and 2020 is as follows:

Approximately 2,600 employees, or 20% of Snap-on’s worldwide workforce, are represented by unions and/or covered under collective bargaining agreements. The number of covered union employees whose contracts expire over the next five years approximates 1,600 employees in 2023, 825 employees in 2024, and 175 employees in 2025; there are no contracts currently scheduled to expire in 2026 or 2027. In recent years, Snap-on has not experienced any significant work slowdowns, stoppages or other labor disruptions.
In the ordinary course of our business, Snap-on is subject to legal disputes that are litigated and/or settled. Although it is not possible to predict the outcome of legal matters, management believes that the results of all legal matters will not have a material impact on Snap-on’s consolidated financial position, results of operations or cash flows.
