The valuation of inventory under the Last-In, First-Out (“LIFO”) method is made at the end of each fiscal year based on inventory levels and costs at that time. Accordingly, interim LIFO calculations, by necessity, are based on estimates of expected fiscal year-end inventory levels and costs, and are subject to final fiscal year-end LIFO inventory calculations.

Inventory held on location for retailers with scan-based trading arrangements, which is included in finished products, totaled $51.3 million, $42.1 million and $36.7 million as of August 26, 2011, February 28, 2011 and August 27, 2010, respectively.
