Inventories are valued at the lower of cost or market and are removed from inventory under the first-in-first-out method (“FIFO”). Cost of inventory includes material, labor and overhead. The Company recorded inventory valuation reserves of $0.3 million and $0.9 million as of June 30, 2011 and September 30, 2010, respectively, to reduce the carrying value of inventories to a net realizable value. If future demand or market conditions are less favorable than the Company’s projections, additional inventory write-downs may be required and would be reflected in cost of sales on the Company’s statement of operations in the period in which the determination is made.
