Product warranties are provided for at the time the Company recognizes revenue. The warranty periods range from ninety days to ten years. The Company estimates these warranty liabilities as a percentage of revenue, based on historical knowledge of warranty costs and expected future warranty costs. If actual product failure rates materially differ from these estimates, revisions to the estimated warranty liability would be required. The Company evaluates its warranty reserve on a quarterly basis.
