m. Leases
In determining whether an arrangement is, or contains a lease, the Group performs an evaluation over the substance of the arrangement. A lease is classified as a finance lease or operating lease based on the substance, not the form of the contract. Finance lease is recognized if the lease transfers substantially all the risks and rewards incidental to the ownership of the leased asset.
Assets and liabilities under a finance lease are recognized in the consolidated statements of financial position at amounts equal to the fair value of the leased assets or, if lower, the present value of the minimum lease payments. Any initial direct costs of the Group are added to the amount recognized as assets.
Minimum lease payments are apportioned between the finance charge and the reduction of the outstanding liability. The finance charge is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability. Contingent rents are charged as expenses in the year in which they are incurred.
Leased assets are depreciated using the same method and based on the useful lives as estimated for directly acquired property and equipment. However, if there is no reasonable certainty that the Group will obtain ownership by the end of the lease terms, the leased assets are fully depreciated over the shorter of the lease terms and their economic useful lives.
Lease arrangements that do not meet the above criteria are accounted for as operating leases for which payments are charged as an expense on the straight-line basis over the lease period.
