12 Months Ended

Dec. 31, 2012

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 18% and 17% of total inventories at December 31, 2012 and 2011, respectively. Cost of other inventories is determined by costing methods that approximate a first-in, first-out ("FIFO") basis.

Inventories were as follows (in millions):



	December 31, 2012			December 31, 2011
Raw materials, work-in-process, and supplies	$	3,697		$	2,847
Finished products	4,614			3,982
Total inventories under FIFO	8,311			6,829
Less: LIFO adjustment	(949		)	(928		)
Total inventories	$	7,362		$	5,901

This may include, but is not limited to, the basis of stating inventory, the method of determining inventory cost, the major classes of inventory, and the nature of the cost elements included in inventory. If inventory is stated above cost, accrued net losses on firm purchase commitments for inventory and losses resulting from valuing inventory at the lower-of-cost-or-market may also be included.
