Basis of preparationThe financial statements have been prepared on the historical cost basis.Revenue recognitionTurnover is measured at the fair value of the consideration received or receivable for goods supplied and services rendered, net of discounts and Value Added Tax.Revenue from the sale of goods is recognised when the significant risks and rewards of ownership have transferred to the buyer (usually on despatch of the goods); the amount of revenue can be measured reliably; it is probable that the associated economic benefits will flow to the entity; and the costs incurred or to be incurred in respect of the transactions can be measured reliably.Income taxThe taxation expense represents the aggregate amount of current and deferred tax recognised in the reporting period. Tax is recognised in profit or loss, except to the extent that it relates to items recognised in other comprehensive income or directly in equity. In this case, tax is recognised in other comprehensive income or directly in equity, respectively.Current tax is recognised on taxable profit for the current and past periods. Current tax is measured at the amounts of tax expected to be paid or recovered using the tax rates and laws that have been enacted or substantively enacted at the reporting date.Tangible assetsTangible assets are initially recorded at cost, and subsequently stated at cost less any accumulated depreciation and impairment losses. Any tangible assets carried at revalued amounts are recorded at the fair value at the date of revaluation less any subsequent accumulated depreciation and subsequent accumulated impairment losses.Finance leases and hire purchase contractsAssets held under finance leases and hire purchase contracts 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.ProvisionsProvisions 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 instrumentsA 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, 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.
