Capital Expenditures At October 31, 2013, 2012, and 2011 respectively, commitments for capital expenditures were $11 million, $48 million, and $44 million respectively. At October 31, 2013, 2012, and 2011, liabilities related to capital expenditures that are included in accounts payable were $2 million, $29 million, and $22 million, respectively. Leases We lease certain land, buildings, and equipment under non-cancelable operating leases and capital leases expiring at various dates through 2024. Operating leases generally have 1 to 20 year terms, with one or more renewal options, with terms to be negotiated at the time of renewal. Various leases include provisions for rent escalation to recognize increased operating costs or require us to pay certain maintenance and utility costs. Our rent expense for the years ended October 31, 2013, 2012, and 2011 was $74 million, $63 million, and $54 million, respectively. Rental income from subleases was $7 million for the year ended October 31, 2013 and $4 million for the years ended October 31, 2012 and 2011. Future minimum lease payments at October 31, 2013, for those leases having an initial or remaining non-cancelable lease term in excess of one year and certain leases that are treated as finance lease obligations, are as follows: (in millions)FinancingArrangementsand CapitalLease Obligations  OperatingLeases Total2014$30 $72 $10220159 61 7020169 47 5620179 39 4820189 33 42Thereafter29 95 124 95 $347 $442Less: Interest portion18    Total$77     Asset Retirement Obligations We have a number of asset retirement obligations in connection with certain owned and leased locations, leasehold improvements, and sale and leaseback arrangements. Certain of our production facilities contain asbestos that would have to be removed if such facilities were to be demolished or undergo a major renovation. The fair value of the conditional asset retirement obligations as of the balance sheet date has been determined to be immaterial. Asset retirement obligations relating to the cost of removing improvements to leased facilities or returning leased equipment at the end of the associated agreements are not material. |
