As of May 31, 2018, we valued approximately 15% of inventories, primarily related to our Energy segment, using the lower of cost, determined on the LIFO method, or net realizable value (19% as of August 31, 2017). If the FIFO method of accounting had been used, inventories would have been higher than the reported amount by $370.4 million and $186.2 million as of May 31, 2018, and August 31, 2017, 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 are subject to the final year-end LIFO inventory valuation.
