Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS	COMMITMENTS Purchase Obligations and Lease Commitments The Company had various purchase obligations at September 30, 2015, totaling $1.6 billion over a period of approximately 30 years for materials, supplies, and energy incident to the ordinary conduct of business. The Company also had various lease commitments for property and equipment under cancelable, noncancelable, and month-to-month operating leases totaling $272 million over a period of approximately 45 years. Of the total lease commitments, approximately 50 percent relate to real property, including office space, storage facilities, and land; approximately 45 percent relate to railcars; and approximately 5 percent relate to machinery and equipment, including computer and communications equipment and production equipment. Guarantees The Company has operating leases with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease as well as other guarantees. Disclosures about each group of similar guarantees are provided below. Residual Value Guarantees The Company has operating leases with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease. These residual value guarantees at September 30, 2015, totaled $121 million and consisted primarily of leases for railcars and company aircraft and will expire beginning in 2016. Management's current expectation is that the likelihood of material residual guarantee payments is remote. Other Guarantees Guarantees and claims also arise during the ordinary course of business from relationships with customers, suppliers, joint venture partners, and other parties when the Company undertakes an obligation to guarantee the performance of others, if specified triggering events occur. Non-performance under a contract could trigger an obligation of the Company. The Company's current other guarantees include guarantees relating primarily to intellectual property, environmental matters, and other indemnifications and have arisen through the normal course of business. The ultimate effect on future financial results is not subject to reasonable estimation because considerable uncertainty exists as to the final outcome of these claims, if they were to occur. These other guarantees have terms up to 30 years with maximum potential future payments of $29 million in the aggregate, with none of these guarantees being individually significant to the Company's operating results, financial position, or liquidity. Management's current expectation is that future payment or performance related to non-performance under other guarantees is remote.
