9. Warranty:

        The Company provides for the estimated cost of product warranties at the time revenue is recognized. Warranty cost is recorded as cost of sales and the reserve balance recorded as an accrued expense in the financial statements. While the Company engages in extensive product quality programs and processes, the Company's warranty obligation is affected by product failure rates and by the related material, labor and delivery costs incurred in correcting a product failure. If actual product failure rates, material or labor costs differ from the Company's estimates, further revisions to the estimated warranty liability would be recorded.
