We generally offer warranty coverage for our products. We accrue warranty related costs under standard warranty terms and for certain claims outside the contractual obligation period that we choose to pay as accommodations to our customers.
Provisions for estimated assurance warranties are recorded at the time of sale and are periodically adjusted to reflect actual experience. The amount of warranty liability accrued reflects management’s best estimate of the expected future cost of honoring Company obligations under its warranty plans. Historically, the cost of fulfilling the Company’s warranty obligations has principally involved replacement parts, towing and transportation costs, labor and travel for any field retrofit campaigns. The Company’s estimates are based on historical experience, the extent of pre-production testing, the number of units involved, and the extent of features/components included in product models. The Company reviews actual warranty claims experience to determine if there are systemic defects that would require a field campaign.
Although we believe the estimates and judgments discussed herein are reasonable, actual results could differ and we may be exposed to increases or decreases in our warranty accrual that could be material.
