Product Warranty Guarantees

9 Product Warranty Guarantees

The company’s products are warranted to provide assurance that the product will function as expected and to ensure customer confidence in design, workmanship, and overall quality. Standard warranty coverage is generally provided for specified periods of time and on select products’ hours of usage, and generally covers parts, labor, and other expenses for non-maintenance repairs. In addition to the standard warranties offered by the company on its products, the company also sells separately priced extended warranty coverage on select products for a prescribed period after the original warranty period expires. For additional information on the contract liabilities associated with the company's separately priced extended warranties, refer to Note 4, Revenue.

At the time of sale, the company recognizes expense and records an accrual by product line for estimated costs in connection with forecasted future warranty claims. The company's estimate of the cost of future warranty claims is based primarily on the estimated number of products under warranty, historical average costs incurred to service warranty claims, the trend in the historical ratio of claims to sales, and the historical length of time between the sale and resulting warranty claim. The company periodically assesses the adequacy of its warranty accruals based on changes in these factors and records any necessary adjustments if the cost of actual claims experience indicates that adjustments to the company's warranty accrual are necessary. Additionally, from time to time, the company may also establish warranty accruals for its estimate of the costs necessary to settle major rework campaigns on a product-specific basis during the period in which the circumstances giving rise to the major rework campaign become known and when the costs to satisfactorily address the situation are both probable and estimable. The warranty accrual for the cost of a major rework campaign is primarily based on an estimate of the cost to repair each affected unit and the number of affected units expected to be repaired.

The changes in accrued warranties were as follows:
