Accrued Warranty

12. Accrued Warranty

The liability is established using historical warranty claim experience. Historical warranty experience is, however, reviewed by management. The current provision may be adjusted to take into account unusual or non-recurring events in the past or anticipated changes in future warranty claims. Adjustments to the initial warranty accrual are recorded if actual claim experience indicates that adjustments are necessary. Warranty reserves are reviewed to ensure critical assumptions are updated for known events that may impact the potential warranty liability.
