Inventory, Policy

Inventories are valued at the lower of cost or market and include material, labor, and overhead. Certain inventories within our North America Contract manufacturing operations are valued using the last-in, first-out (LIFO) method, whereas inventories of other operations are valued using the first-in, first-out (FIFO) method.
