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.

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.

The investment property is accounted for under FRS 102, Section 16 Investment Property. Investment property is remeasured to fair value at each balance sheet date with fair value gains and losses being reported in profit or loss. Investment properties are valued using RICS open market valuation on a freehold basis.
