For lessees, if they can rent the asset for 3 years and they can continue to lease the asset for a nominal $1 rent per year indefinitely after that and the lessee plans to use the asset for 4 years, then does the right of use asset be depreciated by 3 or 4 years in the lessee books?
It is depreciated over the shorter of the lease term and useful life. Here the lease term is indefinite as they would take up the $1 rental option, and the useful life is 4 years. Therefore it is depreciated over the 4 years.
