Exercising adoption options
You can adopt the new standard either by running the adoption process in IBM® Maximo® Real Estate and Facilities or by transitioning existing leases using carryover amounts. The choice between these options depends on the Accounting Start Date of the lease.
If you want to keep the Accounting Start Date before the Lookback Period and/or Adoption Period, it means you want to use ASC840 and ASC842, or IAS17 and IFRS16 in Maximo Real Estate and Facilities. Therefore, to transition your lease, you will have to go with Option 1, running the adoption process in Maximo Real Estate and Facilities.
However, if you want to set the Accounting Start Date to be on or after the Lookback Period and/or Adoption Period, this means that you want to use ASC842 or IFRS16 alone in Maximo Real Estate and Facilities. Therefore, you will perform Option 2, transitioning existing leases using carryover amounts.
