Leases are authorized under the AECA, Section 61, when it is determined that there are compelling foreign policy and national security reasons for leasing rather than selling and the articles are not needed for use during the proposed lease period.

Leases may be written for a maximum of five years with an additional specified period of time required to complete major refurbishment work prior to delivery. Leases may include multiple items with different lease duration periods. The shortest lease period is one month and the longest lease period is sixty months. Leases of one year or more require congressional notification in accordance with the AECA, Section 62(a) (22 U.S.C. 2796a). Leases shall provide that, at any time during the lease period, the may terminate the lease and require the immediate return of the . Leases of less than five years may be extended via an amendment, but the total period under a specific lease may not exceed five years plus the time needed for refurbishment.
Lease amendments may be used to extend or change existing leases. Such changes include variations to payment schedules, Schedule A items, or periods of performance. Each amendment includes the original lease designator and undergoes the same staffing process as the original lease. If a lease for less than one year is amended so that the total period of the original lease and the amendment equals or exceeds one year, Congress must be notified of the amendment before it can be offered.
What does the lessee pay?
The lessee must agree to pay in U.S. dollars all costs incurred by the in leasing articles, including reimbursement for depreciation (rent) of articles while leased. The rental payment is calculated in accordance with 7000.14-R, Volume 15, Chapter 7. Rental payments do not include an administrative charge. The requirement to pay all lease costs does not apply to leases for purposes of cooperative research or development, military exercises, or communications or electronics interface projects. Depreciation may be waived where the leased has passed 75 percent of its service life.
The international partner must agree to pay the costs of restoration or replacement if the articles are lost, damaged, or destroyed while leased. In this case, the international partner is charged the replacement cost (less any depreciation) if the U.S. intends to replace the articles or the actual article value (less any depreciation) if the U.S. does not intend to replace the articles. These charges are recouped under an transaction via a case.
