Warranty

We provide our motorhome customers a comprehensive 12-month/15,000-mile warranty on our Class A, B and C motorhomes, and a 3-year/36,000-mile structural warranty on Class A and C sidewalls and floors. We provide a comprehensive 12-month warranty on all towable products. We have voluntarily agreed to pay certain warranty-type costs to help protect the reputation of our products and the goodwill of our customers. Estimated costs related to product warranty are accrued at the time of sale and are based upon past warranty claims and unit sales history and adjusted as required to reflect actual costs incurred, as information becomes available. A significant increase in dealership labor rates, the cost of parts or the frequency of claims could have a material adverse impact on our operating results for the period or periods in which such claims or additional costs materialize.
