36 After the commencement date, a lessee shall measure the lease liability by:

(a) increasing the carrying amount to reflect interest on the lease liability;

(b) reducing the carrying amount to reflect the lease payments made; and

(c) remeasuring the carrying amount to reflect any reassessment or lease modifications specified in paragraphs 39–46, or to reflect revised in-substance fixed lease payments (see paragraph B42).

37 Interest on the lease liability in each period during the lease term shall be the amount that produces a constant periodic rate of interest on the remaining balance of the lease liability. The periodic rate of interest is the discount rate described in paragraph 26, or if applicable the revised discount rate described in paragraph 41, paragraph 43 or paragraph 45(c).

38 After the commencement date, a lessee shall recognise in profit or loss, unless the costs are included in the carrying amount of another asset applying other applicable Standards, both:

(a) interest on the lease liability; and

(b) variable lease payments not included in the measurement of the lease liability in the period in which the event or condition that triggers those payments occurs.

Reassessment of the lease liability

39 After the commencement date, a lessee shall apply paragraphs 40–43 to remeasure the lease liability to reflect changes to the lease payments. A lessee shall recognise the amount of the remeasurement of the lease liability as an adjustment to the right-of-use asset. However, if the carrying amount of the right-of-use asset is reduced to zero and there is a further reduction in the measurement of the lease liability, a lessee shall recognise any remaining amount of the remeasurement in profit or loss.

40 A lessee shall remeasure the lease liability by discounting the revised lease payments using a revised discount rate, if either:

(a) there is a change in the lease term, as described in paragraphs 20–21. A lessee shall determine the revised lease payments on the basis of the revised lease term; or

(b) there is a change in the assessment of an option to purchase the underlying asset, assessed considering the events and circumstances described in paragraphs 20–21 in the context of a purchase option. A lessee shall determine the revised lease payments to reflect the change in amounts payable under the purchase option.

41 In applying paragraph 40, a lessee shall determine the revised discount rate as the interest rate implicit in the lease for the remainder of the lease term, if that rate can be readily determined, or the lessee’s incremental borrowing rate at the date of reassessment, if the interest rate implicit in the lease cannot be readily determined.
