Turnover is recognised at the fair value of the consideration received or receivab;e for goods and services provided in the normal course of business. The fair value of consideration takes into account trade discounts, settlement discounts and volume rebates.

When cash inflows are deferred and represent a financing arrangement, the fair value of the consideration is the present value of the future receipts. The difference between the fair value of the consideration and the nominal amount received is recognised as interest income.

Turnover for the sale of goods is recognised when all of the following conditions are met:

- The company has transferred the significant risks and rewards of ownership to the buyer;

- The amount of turnover can be recognised reliably; and

- It is probable that the company will receive the consideration due under the transaction.

Turnover from a contract to provide services is recognised in the period in which the services are provided in accordance with the stage of completion of the contract when all of the following conditions are satisfied:

- The amount of turnover can be measured reliably;

- It is probable that the company will receive the consideration due under the contract;

- The stage of completion of the contract at the end of the reporting period can be measured reliably; and

- The costs incurred and the costs to complete the contract can be measured reliably.

Current tax represents the amount expected to be paid or recovered in respect of taxable profits for the financial year and is calculated using the tax rates and laws that have been enacted or substantially enacted at the Balance Sheet date.

Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date where transactions or events have occurred at that date that will result in an obligation to pay more tax in the future, or a right to pay less tax in the future. Timing differences are temporary differences between the company's taxable profits and its results as stated in the financial statements.

Deferred tax is measured on an undiscounted basis at the tax rates that are anticipated to apply in the periods in which the timing differences are expected to reverse, based on tax rates and laws that have been enacted or substantively enacted by the Balance Sheet date.
