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.

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.

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions. At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Short term creditors are measured at transaction price (which is usually the invoice price). Loans and other financial liabilities are initially recognised at transaction price net of any transaction costs and subsequently measured at amortised cost determined using the effective interest method.

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.
