Note 2.  Inventories

Inventories are valued on a lower of last-in, first-out (LIFO) cost or market basis.  At November 30, 2014, August 31, 2014 and November 30, 2013, inventories would have been greater by $2.3 billion, $2.3 billion and $2.2 billion, respectively, if they had been valued on a lower of first-in, first-out (FIFO) cost or market basis.  LIFO inventory costs can only be determined annually when inflation rates and inventory levels are finalized; therefore, LIFO inventory costs for interim financial statements are estimated. Inventory includes product costs, inbound freight, warehousing costs and vendor allowances not classified as a reduction of advertising expense.
