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 2018, 2017 and 2016 is as follows:



(Amounts in millions)	2018			2017			2016
Warranty accrual:
Beginning of year	$	17.2		$	16.0		$	16.4
Additions	14.9			15.2			12.8
Usage	(15.0		)	(14.0		)	(13.2		)
End of year	$	17.1		$	17.2		$	16.0

Approximately 2,650 employees, or 21% 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 875 employees in 2019, 975 employees in 2020, 575 employees in 2021, 175 employees in 2022, and 50 employees in 2023. In recent years, Snap-on has not experienced any significant work slowdowns, stoppages or other labor disruptions.

Snap-on is involved in various legal matters that are being litigated and/or settled in the ordinary course of business. For the year ended December 30, 2017, accruals were recorded for $45.9 million related to judgments in a patent-related litigation matter that is being appealed, and an employment-related litigation matter, which was subsequently settled in 2018. The company recognized a $4.3 million benefit in operating expenses in 2018 as a result of the settlement.

Although it is not possible to predict the outcome of the above and other 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.
