3 Months Ended

Mar. 31, 2015

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 34% and 28% of total inventories at March 31, 2015 and December 31, 2014, 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):



	March 31, 2015			December 31, 2014
Raw materials, work-in-process, and supplies	$	4,178		$	3,822
Finished products	6,331			5,022
Total inventories under FIFO	10,509			8,844
LIFO adjustment	(990		)	(978		)
Total inventories	$	9,519		$	7,866

- Definition

The entire disclosure for inventory. 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. For LIFO inventory, may disclose the amount and basis for determining the excess of replacement or current cost over stated LIFO value and the effects of a LIFO quantities liquidation that impacts net income.
