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.

Revenue from the sale of goods is recognised when the company has transferred to the buyer the significant risks and rewards of ownership of the goods, usually when goods are delivered and legal title has passed. Providing the amount of revenue can be measured reliably, it is probable that the economic benefits associated with the transaction will flow to the company and the costs incurred or to be incurred in respect of the transition can be measured reliably.

Lease payments are recognised as an expense over the lease term on a straight-line basis. The aggregate benefit of lease incentives is recognised as a reduction to expense over the lease term on a straight-line basis.

Deferred taxation is provided on the liability method to take account of timing differences between the treatment of certain items for accounts purposes and their treatment for tax purposes.

Tax deferred or accelerated is accounted for in respect of all material timing differences, in particular accelerated capital allowances and revaluation gains on investment properties. All deferred tax is charged/(credited) to the Income Statement.

A review for indicators of impairment is carried out at each reporting date, with the recoverable amount being estimated where such indicators exist. Where the carrying value exceeds the recoverable amount, the asset is impaired accordingly. Prior impairments are also reviewed for possible reversal at each reporting date.

Stocks are measured at the lower of cost and estimated selling price less costs to complete and sell. Cost includes all costs of purchase, costs of conversion and other costs incurred in bringing the stocks to their present location and condition.
