14. Guarantees

Product Warranty

Our products are generally sold with warranty periods that range from 12 to 36 months following sale or acceptance. The product warranty promises customers that delivered products are as specified in the contract (an “assurance-type warranty”). Therefore, we account for such product warranties under ASC 460, and not as a separate performance obligation. Parts and labor are covered under the terms of the warranty agreement. The warranty provision is based on historical and projected experience by product and configuration.

Changes in accrued warranty were as follows (in thousands):

	Three Months Ended
	March 27,			March 28,
	2021			2020
Balance at beginning of period	$	6,382		$	6,155
Warranty expense accruals		2,409			1,891
Warranty payments		(1,653	)		(1,778	)
Balance at end of period	$	7,138		$	6,268

Accrued warranty amounts expected to be incurred after one year are included in noncurrent other accrued liabilities in the condensed consolidated balance sheet. These amounts totaled $0.6 million and $0.3 million at March 27, 2021 and December 26, 2020, respectively.
