Commitments and Contingencies Disclosure [Abstract]

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 the three months ended March 31, 2018, and April 1, 2017, is as follows:

Snap-on is involved in various legal matters that are being litigated and/or settled in the ordinary course of business. The Condensed Consolidated Balance Sheets as of March 31, 2018, and December 30, 2017, included fiscal 2017 accruals of $30.9 million related to a judgment in a patent-related litigation matter, as well as $15.0 million related to a judgment in an employment-related litigation matter brought by an individual; both judgments are being appealed.

Although it is not possible to predict the outcome of these 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.
