In determining the incremental borrowing rates, management considers the term of the lease, the nature of the asset being leased and the funding strategy and principles applied by the group's treasury department.

b) Extensions and termination options

In determining the lease term, management considers all facts and circumstances that create an economic incentive to exercise an extension option, or not exercise a termination option. Extension options (or periods after termination options) are only included in the lease term if the lease is reasonably certain to be extended (or not terminated). The assessment is reviewed if a significant event or a significant change in circumstances occurs which affects this assessment and that is within the control of the lessee.
