We have several aircraft modernization programs under way that are supported by the purchase of Boeing 777 Freighter (“B777F”) and Boeing 767-300 Freighter (“B767F”) aircraft. These aircraft are significantly more fuel-efficient per unit than the aircraft types previously utilized, and these expenditures are necessary to achieve significant long-term operating savings and to replace older aircraft. Our ability to delay the timing of these aircraft-related expenditures is limited without incurring significant costs to modify existing purchase agreements.

As of May 31, 2023, we had $1.0 billion in deposits and progress payments on aircraft purchases and other planned aircraft-related transactions. These deposits are classified in the “Other assets” caption of our accompanying consolidated balance sheets. Aircraft and aircraft-related contracts are subject to price escalations. The following table is a summary of the aircraft we were committed to purchase as of May 31, 2023, with the year of expected delivery:
