In all leases, whether we are the lessor or lessee, we define lease term as the non-cancellable term of the lease plus any renewals covered by renewal options that are reasonably certain of exercise based on our assessment of economic factors relevant to the lessee. The non-cancellable term of the lease commences on the date the lessor makes the underlying property in the lease available to the lessee, irrespective of when lease payments begin under the contract.

We have operating leases for certain cinemas, and finance leases for certain equipment assets. Our leases have remaining lease terms of 1 to 25 years, with certain leases having options to extend to up to a further 20 years. Lease payments for our cinema operating leases consist of fixed base rent, and for certain leases, variable lease payments consisting of contracted percentages of revenue, changes in the relevant CPI, and/or other contracted financial metrics.

We have entered into various leases as a lessor for our owned real estate properties. These leases vary in length between 1 and 20 years, with certain leases containing options to extend at the behest of the applicable tenants. Lease components consist of fixed base rent, and for certain leases, variable lease payments consisting of contracted percentages of revenue, changes in the relevant CPI, and/or other contracted financial metrics. None of our leases grant any right to the tenant to purchase the underlying asset.
