Inventory obsolescence is determined by identifying specific items based on the age of inventory and by establishing a general reserve based on annual purchases. Analyzing inventory by age showed little movement once items have aged five years, and historical trends showed that 1.1% of purchases would eventually be scrapped. Accordingly, the Company uses these two factors in determining the amount of the reserve.
