18 An entity shall determine the lease term as the non-cancellable period of a lease, together with both:

(a) periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and

(b) periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option.

19 In assessing whether a lessee is reasonably certain to exercise an option to extend a lease, or not to exercise an option to terminate a lease, an entity shall consider all relevant facts and circumstances that create an economic incentive for the lessee to exercise the option to extend the lease, or not to exercise the option to terminate the lease, as described in paragraphs B37–B40.

20 A lessee shall reassess whether it is reasonably certain to exercise an extension option, or not to exercise a termination option, upon the occurrence of either a significant event or a significant change in circumstances that:

(a) is within the control of the lessee; and

(b) affects whether the lessee is reasonably certain to exercise an option not previously included in its determination of the lease term, or not to exercise an option previously included in its determination of the lease term (as described in paragraph B41).

21 An entity shall revise the lease term if there is a change in the non-cancellable period of a lease. For example, the non-cancellable period of a lease will change if:

(a) the lessee exercises an option not previously included in the entity’s determination of the lease term;

(b) the lessee does not exercise an option previously included in the entity’s determination of the lease term;

(c) an event occurs that contractually obliges the lessee to exercise an option not previously included in the entity’s determination of the lease term; or

(d) an event occurs that contractually prohibits the lessee from exercising an option previously included in the entity’s determination of the lease term.
