The following is a summary of the future commitments for operating lease obligations, material purchase commitments, outsourcing and other arrangements: (Millions of Dollars) Total 2011 2012 2013 2014 2015 Thereafter Operating lease obligations $ 309.1 $ 97.0 $ 72.9 $ 51.6 $ 32.7 $ 19.7 $ 35.2 Inventory purchase commitments 328.6 328.6           Marketing and other commitments 71.8 55.5 4.7 2.7 1.8 1.8 5.3 Total $ 709.5 $ 481.1 $ 77.6 $ 54.3 $ 34.5 $ 21.5 $ 40.5 The Company has numerous assets, predominantly vehicles and equipment, under a one-year term U.S. master personal property lease. Residual value obligations under this master lease were $9.8 million at January 1, 2011 while the fair value of the underlying assets was approximately $11.3 million. The U.S. master personal property lease obligations are not reflected in the future minimum lease payments since the initial and remaining term does not exceed one year. The Company routinely exercises various lease renewal options and from time to time purchases leased assets for fair value at the end of lease terms. The Company is a party to a synthetic lease for one of its major distribution centers. The program qualifies as an operating lease for accounting purposes, where only the monthly lease cost is recorded in earnings and the liability and value of underlying assets are off-balance sheet.
