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.

Purchased goodwill arises on business acquisitions and represents the difference between the cost of acquisition and the fair values of the identifiable assets and liabilities acquired.

Goodwill is initially recorded at cost, and is subsequently stated at cost less any accumulated amortisation and accumulated impairment losses. It is amortised on a straight-line basis over the useful economic life of the asset. Where a reliable estimate of the useful life of goodwill cannot be made, the life is presumed not to exceed five years.

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

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.

A financial asset or a financial liability is recognised only when the entity becomes a party to the contractual provisions of the instrument.

Basic financial instruments are initially recognised at the transaction price and are subsequently measured as follows: Debt instruments are subsequently measured at amortised cost and commitments to receive a loan and to make a loan to another entity are subsequently measured at amortised cost. Where investments in non-convertible preference shares and non-puttable ordinary shares or preference shares are publicly traded or their fair value can otherwise be measured reliably, the investment is subsequently measured at fair value with changes in fair value recognised in profit or loss. All other such investments are subsequently measured at cost less impairment.

All other financial instruments, including derivatives, are initially recognised at fair value, which is normally the transaction price and are subsequently measured at fair value, with any changes recognised in profit or loss.

Financial assets that are measured at cost or amortised cost are reviewed for objective evidence of impairment at the end of each reporting date. If there is objective evidence of impairment, an impairment loss is recognised in profit or loss immediately.

All equity instruments regardless of significance, and other financial assets that are individually significant, are assessed individually for impairment. Other financial assets or either assessed individually or grouped on the basis of similar credit risk characteristics.

Any reversals of impairment are recognised in profit or loss immediately, to the extent that the reversal does not result in a carrying amount of the financial asset that exceeds what the carrying amount would have been had the impairment not previously been recognised.

Provisions are recognised when the entity has an obligation at the reporting date as a result of a past event; it is probable that the entity will be required to transfer economic benefits in settlement and the amount of the obligation can be estimated reliably. Provisions are recognised as a liability in the statement of financial position and the amount of the provision as an expense.

Provisions are initially measured at the best estimate of the amount required to settle the obligation at the reporting date and subsequently reviewed at each reporting date and adjusted to reflect the current best estimate of the amount that would be required to settle the obligation. Any adjustments to the amounts previously recognised are recognised in profit or loss unless the provision was originally recognised as part of the cost of an asset. When a provision is measured at the present value of the amount expected to be required to settle the obligation, the unwinding of the discount is recognised in finance costs in profit or loss in the period it arises.
