Flight Equipment

Flight equipment held for lease is stated at cost and depreciated using the straight-line method over a 25 year life from the date of manufacture to estimated residual values.

Estimated residual values are generally determined to be approximately 15% of the manufacturer’s estimated realized price for flight equipment when new. Management may, at its discretion, make exceptions to this policy on a case-by-case basis when, in its judgment, the residual value calculated pursuant to this policy does not appear to reflect current expectations of value. Examples of situations where exceptions may arise include but are not limited to:

In accounting for flight equipment held for lease, we make estimates about the expected useful lives, the fair value of attached leases and the estimated residual values. In estimating useful lives, fair value of leases and residual values of our aircraft, we rely upon actual industry experience with the same or similar aircraft types and our anticipated utilization of the aircraft.

Determining the fair value of attached leases requires us to make assumptions regarding the current fair values of leases for specific aircraft. We estimate a range of fair values of like aircraft in order to determine if the attached lease is within a fair value range. If a lease is below or above fair value range, we present value the estimated amount below or above fair value range over the remaining term of the lease. Lease premiums or discounts are amortized into lease rental income over the remaining term of the lease.

Our flight equipment held for lease is evaluated for impairment when events and circumstances indicate that the assets may be impaired. Indicators include third party appraisals of our aircraft, adverse changes in market conditions for specific aircraft types and the occurrence of significant adverse changes in general industry and market conditions that could affect the fair value of our aircraft.
