These have been prepared in compliance with FRS 102 Section 1A, 'The Financial Reporting Standard applicable to the UK and Republic of Ireland'.

Current tax is recognised on taxable profit for the current and past periods. Current tax is measured at the amounts of tax expected to pay or recover using the tax rates and laws that have been enacted or substantively enacted at the reporting date.

Tangible assets are initially measured at cost, and are subsequently measured at cost less any accumulated depreciation and accumulated impairment losses.

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.

Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the reporting date. Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is more likely than not that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Deferred tax is measured on an undiscounted basis at the tax rates that would apply in the periods in which timing differences are expected to reverse, based on tax rates and laws enacted at the statement of financial position date.
