Inventories are stated at the lower of cost or net realizable value. Cost is determined using the average cost method. The inventory valuations above were developed using normalized production capacities for each of our manufacturing locations. Any costs from abnormal excess capacity or under-utilization of fixed production overheads are expensed in the period incurred and are not included as a component of inventory valuation.
