A fair market value purchase option is a clause in an equipment lease or vehicle lease that gives you the right, but not the obligation, to buy the leased asset at the end of the lease term for whatever its fair market value is at that time. You do not know the purchase price upfront. The price is determined at lease-end based on an independent appraisal or a formula defined in the lease agreement. This is the opposite of a fixed-price purchase option, where the buyout price is set the day you sign.
Fair market value options are standard in operating leases and equipment financing where the lessor wants to retain residual value exposure to the asset.
When your lease expires, the lessor obtains an appraisal of the asset's current worth. Some agreements define fair market value as the price a willing buyer and willing seller would agree to in an arm's-length transaction, with neither party under compulsion to act. Others use a specific third-party appraiser named in the lease or a standardized valuation guide for the asset class, such as Kelley Blue Book for vehicles or an industry publication for commercial equipment.
If you believe the appraised value is too high, most well-drafted leases give you a period to negotiate or dispute it, sometimes with binding arbitration as the resolution mechanism.
A lessor who grants a fixed-price purchase option locks in the future sale price on day one. If the asset holds its value better than expected, the lessee captures all of that upside by exercising the option below market. The lessor absorbs the loss.
A fair market value option eliminates that risk. The lessor retains upside on the residual value. If the equipment holds value well, you pay more to buy it. The lessor's residual value position is protected regardless of how asset markets evolve over the lease term.
The presence of a fair market value purchase option is one of the criteria that determines whether a lease qualifies as an operating lease or a finance lease under ASC 842, the lease accounting standard effective in the United States for fiscal years beginning after December 15, 2018. If the option price is not a bargain, meaning the lessee is not reasonably certain to exercise it, the lease generally remains an operating lease for accounting purposes.
For tax purposes, the IRS looks at whether the lease is a true lease or a disguised purchase. A fair market value option at lease-end strongly supports true lease treatment, because neither party has entered into an agreement that makes purchase inevitable or economically compelled.
