The amounts reflected in the table above for purchase commitments represent noncancelable agreements to purchase goods or services. As of August 31, 2013, our obligation to purchase four Boeing 767-300 Freighter (“B767F”) aircraft and nine Boeing 777 Freighter (“B777F”) aircraft is conditioned upon there being no event that causes us or our employees not to be covered by the Railway Labor Act of 1926, as amended. Commitments to purchase aircraft in passenger configuration do not include the attendant costs to modify these aircraft for cargo transport unless we have entered into noncancelable commitments to modify such aircraft. Open purchase orders that are cancelable are not considered unconditional purchase obligations for financial reporting purposes and are not included in the table above.

During the first quarter of 2014, we entered into supplemental agreements to purchase the 16 Boeing 757 (“B757”) option aircraft pursuant to an agreement originally entered into in March 2013. Delivery of the aircraft will occur through 2015.

We had $416 million in deposits and progress payments as of August 31, 2013 on aircraft purchases and other planned aircraft-related transactions. These deposits are classified in the “Other assets” caption of our consolidated balance sheets. In addition to our commitment to purchase B777Fs and B767Fs, our aircraft purchase commitments include the B757 aircraft in passenger configuration, which will require additional costs to modify for cargo transport. Aircraft and aircraft-related contracts are subject to price escalations. The following table is a summary of the key aircraft we are committed to purchase as of August 31, 2013 with the year of expected delivery:

	B757	B767F	B777F	Total

While certain of our lease agreements contain covenants governing the use of the leased assets or require us to maintain certain levels of insurance, none of our lease agreements include material financial covenants or limitations.
