We warrant certain equipment against defects in design, materials and workmanship, generally for a period of one year.  Upon delivery of that equipment, we establish, as part of Cost of goods sold, a provision for the expected costs of such warranty based on historical experience, specific warranty terms and customer feedback.  A review is performed on a quarterly basis to assess the adequacy of our warranty accrual.
