Additionally, the Company 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. Revenue is recognized on extended warranty contracts when the revenue recognition criteria are met, resulting in ratable recognition over the contract term. The amortization of deferred revenue is recorded to net sales in the condensed consolidated statements of comprehensive income. The following is a tabular reconciliation of the deferred revenue related to extended warranty coverage:

	2020			2019			2020			2019
