The formulas
- Impairment = carrying amount - fair value (when the asset group fails recoverability under ASC 360)
- Amortization = ROU after impairment / remaining term
- First-year cost = amortization + liability x rate
How it works
A lessee tests an ROU asset for impairment under ASC 360 at the asset group level. After an impairment, ASC 842-20-35-10 measures the ROU asset at its carrying amount after the impairment less accumulated amortization, amortized from the impairment date to the earlier of the end of its useful life or the end of the lease term.
For an operating lease, ASC 842-20-25-7 then calculates the single lease cost as straight-line amortization of the impaired ROU asset plus accretion of the lease liability. The cost is no longer level: accretion falls as the liability is paid down.

Common questions
Does the lease liability change?
No. The impairment reduces only the ROU asset. The liability keeps its measurement.
Where is the impairment presented?
In the same line as other ASC 360 impairment losses for the asset group.
Is the amortization still straight-line?
Yes, straight-line over the remaining term. The combined cost is front-loaded because interest is higher early on.
