Provisions 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 as a finance cost in profit or loss in the period it arises. Financial instruments A financial asset or a financial liability is recognised only when the company becomes a party to the contractual provisions of the instrument. Basic financial instruments are initially recognised at the transaction price, unless the arrangement constitutes a financing transaction, where it is recognised at the present value of the future payments discounted at a market rate of interest for a similar debt instrument. Debt instruments 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. Other financial instruments, including derivatives, are initially recognised at fair value, unless payment for an asset is deferred beyond normal business terms or financed at a rate of interest that is not a market rate, in which case the asset is measured at the present value of the future payments discounted at a market rate of interest for a similar debt instrument. Other financial instruments are subsequently measured at fair value, with any changes recognised in profit or loss, with the exception of hedging instruments in a designated hedging relationship. 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. For all equity instruments regardless of significance, and other financial assets that are individually significant, these are assessed individually for impairment. Other financial assets are 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.
