Current tax represents the amount of tax payable or receivable in respect of the taxable profit (or loss) for the current or past reporting periods. It is measured at the amount expected to be paid or recovered using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

Deferred tax represents the future tax consequences of transactions and events recognised in the financial statements of current and previous periods. It is recognised in respect of all timing differences, with certain exceptions. Timing differences are differences between taxable profits and total comprehensive income as stated in the financial statements that arise from the inclusion of income and expense in tax assessments in periods different from those in which they are recognised in the financial statements. Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Deferred tax is measured using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date that are expected to apply to the reversal of timing differences. Deferred tax on revalued, non-depreciable tangible fixed assets and investment properties is measured using the rates and allowances that apply to the sale of the asset.

Investments in equity shares which are publicly traded or where the fair value can be measured reliably are initially measured at fair value, with changes in fair value recognised in profit or loss. Investments in equity shares which are not publicly traded and where fair value cannot be measured reliably are measured at cost less impairment.

Interest income on debt securities, where applicable, is recognised in income using the effective interest method.

Dividends on equity securities are recognised in income when receivable.

Cash and cash equivalents comprise cash on hand and call deposits, and other short-term highly liquid investments that are readily convertible to a known amount of cash and are subject to an insignificant risk of change in value.

Trade debtors are amounts due from customers for goods and services provided in the ordinary course of business.

Trade debtors are recognised initially at the transaction price. They are subsequently measured at amortised cost using the effective interest method, less provision for impairment. A provision for the impairment of trade debtors is established when there is objective evidence that the company will not be able to collect all amounts due according to the original terms of the receivables.

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Accounts payable are classified as current liabilities if the company does not have an unconditional right, at the end of the reporting period, to defer settlement of the creditor for at least twelve months after the reporting date. If there is an unconditional right to defer settlement for at least twelve months after the reporting date, they are presented as non-current liabilities.

Trade creditors are recognised initially at the transaction price and subsequently measured at amortised cost using the effective interest method.

Leases in which substantially all the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to profit or loss on a straight-line basis over the period of the lease.

Ordinary shares are classified as equity. Equity instruments are measured at the fair value of the cash or other resources received or receivable, net of the direct costs of issuing the equity instruments. If payment is deferred and the time value of money is material, the initial measurement is on a present value basis.
