Accrued Warranty

Accrued Warranty

The Company warrants its products against defect for 12 months, however, for certain products a customer may purchase an extended warranty. A provision for estimated future costs and estimated returns for credit relating to such warranty is recorded in the period when product is shipped and revenue recognized, and is updated as additional information becomes available. The Company’s estimate of future costs to satisfy warranty obligations is based primarily on historical warranty expense experienced and a provision for potential future product failures. Changes in the accrued warranty for fiscal years ended 2019, 2018 and 2017 are as follows:
