Which of the following is NOT a typical operating lease cost?

In the context of operating leases, typical costs associated with the leasing arrangement include lease costs, maintenance reserves, and potentially security deposits. An operating lease is characterized by the lessee not bearing the risks and rewards of ownership of the asset, which influences the cost components associated with it.

The purchase price of an aircraft, however, is not considered a typical operating lease cost because it pertains to the outright acquisition of the asset rather than leasing it. Under an operating lease, the lessee does not purchase the aircraft but instead pays for the right to use it without taking on ownership. As a result, the purchase price is not factored into the costs associated with leasing the aircraft, making it the correct choice for the question.

Understanding this distinction is crucial in differentiating between the costs of leasing versus owning an asset, especially in industries like aviation where leasing arrangements are common.
