As of February 28, 2014, we valued approximately 14% of inventories, primarily related to Energy, using the lower of cost, determined on the LIFO method, or market (16% and 14% as of August 31, 2013 and February 28, 2013, respectively). If the FIFO method of accounting had been used, inventories would have been higher than the reported amount by $579.4 million, $652.6 million and $535.1 million at February 28, 2014, August 31, 2013 and February 28, 2013, respectively. 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 at that time. Interim LIFO calculations are based on management's estimates of expected year-end inventory levels and costs, and are subject to the final year-end LIFO inventory valuation.
