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 transaction can be measured reliably.

Revenue from the rendering of services is recognised by reference to the stage of completion of the contract. The stage of completion of a contract is measured by comparing the costs incurred for work performed to date to the total estimated contract costs. Turnover is only recognised to the extent of recoverable expenses when the outcome of a contract cannot be estimated reliably.

Finance costs charged to the profit or loss include interest expense calculated using the effective interest method from FRS 102:11, finance charges on finance leases, and exchange differences on foreign currency borrowings where these are treated as an adjustment to interest costs.

Current tax is recognised in profit or loss, except for taxes related to revaluations of land and buildings which are recognised in other comprehensive income.

Current tax represents the amount of tax payable (receivable) in respect of taxable profit (loss) for the current, or past, reporting periods. Current tax is measured at the amount expected to be paid (recovered) using the tax rates and laws which have been enacted, or substantively enacted, by the balance sheet date. Where payments to HM Revenue and Customs exceed liabilities owed, an asset is recognised to the extent of the amount of tax recoverable.

Deferred tax is recognised in respect of all timing differences between the recognition of income and expenses in the financial statements and their inclusion in tax assessments. 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 reporting date and that are expected to apply to the reversal of the timing difference, except for revalued land and investment property where the tax rate that applies to the sale of the asset is used. Current and deferred tax assets and liabilities are not discounted.

A related party is a person or entity that is related to the company. This includes individuals with control or significant influence, members of key management personnel, and entities within the same group. All transactions with related parties are disclosed in the notes to the financial statements. Disclosure includes the nature of the related party relationship, the amount of the transactions, and any outstanding balances and commitments at the reporting date. As permitted by FRS 102, disclosure is not required of transactions entered into between two or more members of a group, provided that any subsidiary which is a party to the transaction is wholly owned by such a member.

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new ordinary shares or options are shown in equity as a deduction, net of tax, from the proceeds.
