INVENTORIES

NOTE 4 - INVENTORIES

 

Inventories are valued using the last-in, first-out (LIFO) method. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs existing at that time. Accordingly, interim LIFO calculations must necessarily be based on management's estimates of expected year-end inventory levels and costs. Because these are subject to many factors beyond management's control, interim results are subject to the final year-end LIFO inventory valuation.
