INVENTORIES


All inventories are stated at the lower of cost or market. Cost for a substantial portion of U.S. inventories is determined on a last-in, first-out ("LIFO") basis. LIFO was used for approximately 32% of total inventories at
June 30, 2011 and December 31, 2010. Cost of other inventories is determined on a first-in, first-out ("FIFO") basis.
