8. Inventories
 
Inventories, which consist of purchased semi-finished metal products, are stated at the lower of cost or market value.  Cost is determined by the specific-identification method. Inventory is purchased for specific customer orders and the Company’s own inventory.  The carrying amount of inventory, which is hedged by futures contracts designated as fair value hedges, is adjusted to fair value.
