12. 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						Nine Months Ended
	September 26,			September 28,			September 26,			September 28,
	2020			2019			2020			2019
Balance at beginning of period	$	5,996		$	6,852		$	6,155		$	8,014
Warranty expense accruals		911			1,137			3,846			4,695
Warranty payments		(1,169	)		(2,071	)		(4,263	)		(6,791	)
Balance at end of period	$	5,738		$	5,918		$	5,738		$	5,918

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 $0.1 million and $0.3 million at September 26, 2020 and December 28, 2019, respectively.
