Inventories are stated at the lower of cost or estimated net realizable value. Cost is primarily determined based on the first-in, first-out inventory method ("FIFO") or average cost methods, which approximates current replacement cost. However, certain subsidiaries use the last-in, first-out inventory method ("LIFO").
