Guarantees and Indemnifications [Abstract]
Guarantees and Indemnifications	NOTE 16: GUARANTEES AND INDEMNIFICATIONS In conjunction with certain transactions, primarily the lease, sale or purchase of operating assets or services in the ordinary course of business, we may provide routine guarantees or indemnifications (e.g., environmental, fuel, tax and software infringement), the terms of which range in duration, and often they are not limited and have no specified maximum obligation. As a result, the overall maximum potential amount of the obligation under such guarantees and indemnifications cannot be reasonably estimated. Historically, we have not been required to make significant payments under our guarantee or indemnification obligations and no amounts have been recognized in our financial statements for the underlying fair value of these obligations. Special facility revenue bonds have been issued by certain municipalities primarily to finance the acquisition and construction of various airport facilities and equipment. These facilities were leased to us and are accounted for as operating leases. FedEx Express has unconditionally guaranteed $483 million in principal of these bonds (with total future principal and interest payments of approximately $578 million as of May 31, 2015) through these leases.

In conjunction with certain transactions, primarily the lease, sale or purchase of operating assets or services in the ordinary course of business, we may provide routine guarantees or indemnifications (e.g., environmental, fuel, tax and software infringement), the terms of which range in duration, and often they are not limited and have no specified maximum obligation. As a result, the overall maximum potential amount of the obligation under such guarantees and indemnifications cannot be reasonably estimated. Historically, we have not been required to make significant payments under our guarantee or indemnification obligations and no amounts have been recognized in our financial statements for the underlying fair value of these obligations.
