Leases in which substantially all the risks and rewards of ownership are retained by the lessor are classified as
operating leases. Payments made under operating leases are charged to profit or loss on a straight-line basis over
the period of the lease.
Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and
rewards of ownership to the lessee.
Assets held under finance leases are recognised at the lower of their fair value at inception of the lease and the
present value of the minimum lease payments. These assets are depreciated on a straight-line basis over the
shorter of the useful life of the asset and the lease term. The corresponding liability to the lessor is included in
the balance sheet as a finance lease obligation.
Lease payments are apportioned between finance costs in the profit and loss account and reduction of the lease
obligation so as to achieve a constant periodic rate of interest on the remaining balance of the liability.
