Case 2.4 Walgreen Co. and Subsidiaries The following excerpts are from the 2010 Walgreen Co. Form 10-K: Inventories Inventories are valued on a lower of last-in, first-out (LIFO) cost or market basis. At August 31, 2010 and 2009 , inventories would have been greater by $1,379 million and $1,239 million, respectively, if they had been valued on a lower of first-in, first-out (FIFO) cost or market basis. Inventory includes product costs, inbound freight, warehousing costs, and vendor allowances. 3. Leases The Company owns 20.2% of its operating locations; the remaining locations are leased premises. Initial terms are typically 20 to 25 years, followed by additional terms containing cancellation options at five-year intervals, and may include rent escalation clauses. The commencement date of all lease terms is the earlier of the date the Company becomes legally obligated to make rent payments or the date the Company has the right to control the property. Additionally, the Company recognizes rent expense on a straight-line basis over the term of the lease. In addition to minimum fixed rentals, most leases provide for contingent rentals based upon a portion of sales. Minimum rental commitments at August 31,2010, under all leases having an initial or remaining noncancelable term of more than one year are shown below (In millions): WALGREEN CO.
