Inventory consists primarily of used oil, processed oil, catalyst, new and used solvents, new and refurbished parts cleaning machines, drums, accessories, and absorbents. Inventories are valued at the lower of first-in, first-out (FIFO) cost or market, net of any reserves for excess, obsolete, or unsalable inventory. The Company continually monitors its inventory levels at each of its locations and evaluates inventories for excess or slow-moving items. If circumstances indicate the cost of inventories exceed their recoverable value, inventories are reduced to net realizable value.
