Inventory is generally valued at the lower of last-in, first-out (“LIFO”) cost or market. Other inventories of the Company are valued at average cost or net realizable value, whichever is lower. An actual valuation of inventory under the LIFO method is made at the end of each year based on the inventory levels and costs at that time. Interim LIFO calculations are based on management’s estimates of expected year-end levels and costs.
