Remeasurement of variable lease payments The initial measurement of lease-related assets and liabilities is similar under ASC 842 and IFRS 16; however, subsequent changes in lease payments that vary with a rate or index (e.g., rents that increase for changes in an inflation index) are accounted for differently. Under ASC 842, such changes are recognized when incurred, unless the lessee is otherwise required to remeasure the lease liability (e.g., as a result of reassessing the lease term). Under IFRS 16, lease assets and liabilities are remeasured whenever the cash flow changes. Sale and leaseback accounting Under ASC 842, a seller-lessee would recognize the full gain from a sale and leaseback transaction that qualifies as a sale. IFRS 16 limits the recognition of gains from sale and leaseback transactions. Transition ASC 842 requires a modified retrospective approach to each lease that existed at the beginning of the earliest comparative period presented in the financial statements, as well as leases entered into after that date. IFRS 16 allowsa reporting entity to elect a full retrospective approach.
