Leasehold improvements are amortized over the period of the lease or the useful life of the improvement, whichever is shorter.
Leasehold improvements that are placed in service after the start of the lease term are amortized over the shorter of the useful life of the asset or the remaining lease term, including renewal options that are reasonably assured to be executed.
