As part of its activities, the group typically leases items such as land, buildings and vehicles. The group does not typically lease assets on a short-term basis or enter into leases for low value assets and therefore no material costs were incurred during the year, either individually or in aggregate, in relation to lease contracts with a duration of less than 12 months or for low value assets.

Lease terms range from one year to 999 years. Due to the nature of the group's operations, many of the group's leases have extremely long terms.

The maturity profile in the following table represents the future contractual lease payments on an undiscounted basis.
