Turnover is measured at the fair value of the consideration received or receivable, net of discounts and value added taxes. Turnover includes revenue earned from the sale of goods and from the rendering of services.

Turnover from the sale of goods is recognised when the significant risks and rewards of ownership of the goods has transferred to the buyer.

Turnover from the rendering of services is recognised when the service is performed.

Assets obtained under hire purchase contracts or finance leases are capitalised in the balance sheet. Those held under hire purchase contracts are depreciated over their estimated useful lives.  Those held under finance leases are depreciated over their estimated useful lives or the lease term, whichever is the shorter.

The interest element of these obligations is charged to profit or loss over the relevant period. The capital element of the future payments is treated as a liability.

Rentals paid under operating leases are charged to profit or loss on a straight line basis over the period of the lease.

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.
