Warranty Accruals
Note 8 – Warranty Accruals
Warranty costs are estimated and charged to operations to cover a defined warranty period. The estimated warranty cost is based on the history of warranty claims for each particular product type. For new product types without a warranty history, preliminary estimates are based on historical information for similar product types. The warranty accruals, included in Accounts payable and accrued liabilities on the Consolidated Balance Sheets, are reviewed periodically and updated based on warranty trends and expirations of warranty periods.
