Under IFRS 16, a lessee measures the right-of-use (ROU) asset at initial recognition based on the initial lease liability plus specific adjustments, and depreciates it systematically over the shorter of the lease term or the asset's useful life.
How IFRS 16 Right-of-Use Asset Calculation Works
Initial measurement of the ROU asset (IFRS 16.24): The ROU asset comprises: (i) the initial measurement of the lease liability (present value of future lease payments discounted at the incremental borrowing rate or implicit rate); (ii) any lease payments made at or before commencement, less lease incentives received; (iii) initial direct costs incurred by the lessee; and (iv) an estimate of costs to dismantle/restore the underlying asset where an obligation exists (IAS 37 provision).
Lease liability measurement (IFRS 16.26): The lease liability is the present value of unpaid lease payments, including fixed payments (net of incentives), variable payments based on an index or rate, residual value guarantees, and exercise prices of purchase options reasonably certain to be exercised. Variable lease payments not tied to an index or rate are excluded and expensed as incurred.
