Product Warranty Obligations

The Company records a liability for standard product warranty obligations accounted for as assurance warranties at the time of sale to a customer based upon historical warranty experience. The Company also records a liability for specific warranty matters when they become known and are reasonably estimable. The following is a tabular reconciliation of the Company’s standard product warranty liability accounted for as an assurance warranty:

	*Year Ended December 31,*
	*2021*			*2020*			*2019*
Balance at beginning of period	$	59,218		$	49,316		$	41,785
Product warranty reserve assumed in acquisition		3,932			124			1,062
Payments		(42,682	)		(33,496	)		(26,096	)
Provision for warranty issued		69,280			42,093			32,060
Changes in estimates for pre-existing warranties		4,465			1,181			505
Balance at end of period	$	94,213		$	59,218		$	49,316

The Company also sells extended warranty coverage for certain products, which it accounts for as a service warranty. The sales of extended warranties are recorded as deferred revenue, and typically have a duration of five to ten years. The deferred revenue related to extended warranty coverage is amortized over the duration of the extended warranty contract period, following the standard warranty period, using the straight-line method. The Company believes the straight-line method is appropriate because the performance obligation is satisfied based on the passage of time. The amortization of deferred revenue is recorded to net sales in the consolidated statements of comprehensive income. The following is a tabular reconciliation of the deferred revenue related to extended warranty coverage:

	*Year Ended December 31,*
	*2021*			*2020*			*2019*
Balance at beginning of period	$	89,788		$	78,738		$	68,340
Extended warranty contracts issued		41,560			26,968			24,483
Amortization of extended warranty contracts		(19,701	)		(15,918	)		(14,085	)
Balance at end of period	$	111,647		$	89,788		$	78,738

The timing of recognition of the Company’s deferred revenue balance related to extended warranties at December 31, 2021 is as follows:

2022	$	21,210
2023		22,051
2024		19,282
2025		15,413
After 2025		33,691
Total	$	111,647

The Company has a post-sale extended warranty marketing program with a third party. In the program’s agreement, the Company is required to pay fees to the third-party service provider based on the number of extended warranty contracts that they sell, which it classifies as costs to obtain a contract. These fees are deferred and recorded as other assets in the consolidated balance sheets, and then amortized to net sales in the consolidated statements of comprehensive income over the same period that the underlying deferred revenue is recognized. The balance of deferred contract costs as of December 31, 2021 and 2020 was $8,479 and $6,869, respectively. Amortization of deferred contract costs recorded during the years ended December 31, 2021, 2020 and 2019 was $1,739, $1,303 and $869, respectively.
