Current tax is recognised on taxable profit for the current and past periods. Current tax is measured at the amounts of tax expected to pay or recover using the tax rates and laws that have been enacted or substantively enacted at the reporting date.

Research expenditure is written off in the period in which it is incurred. Development expenditure incurred is capitalised as an intangible asset only when It is technically feasible to complete the intangible asset so that it will be available for use or sale; there is the intention to complete the intangible asset and use or sell it; there is the ability to use or sell the intangible asset; the use or sale of the intangible asset will generate probable future economic benefits; there are adequate technical, financial and other resources available to complete the development and to use or sell the intangible asset; and the expenditure attributable to the intangible asset during its development can be measured reliably. Expenditure that does not meet the above criteria is expensed as incurred.

Tangible assets are initially measured at cost, and are subsequently measured at cost less any accumulated depreciation and accumulated impairment losses or at a revalued amount.

A review for indicators of impairment is carried out at each reporting date, with the recoverable amount being estimated where such indicators exist. Where the carrying value exceeds the recoverable amount, the asset is impaired accordingly. Prior impairments are also reviewed for possible reversal at each reporting date.

Assets held under finance leases are recognised in the statement of financial position as assets and liabilities at the lower of the fair value of the assets and the present value of the minimum lease payments, which is determined at the inception of the lease term. Any initial direct costs of the lease are added to the amount recognised as an asset.

Lease payments are apportioned between the finance charges and reduction of the outstanding lease liability using the effective interest method. Finance charges are allocated to each period so as to produce a constant rate of interest on the remaining balance of the liability.
