Turnover
Turnover comprises the invoiced value of goods and services supplied by the company, net of Value Added Tax and trade discounts.
Taxation
Taxation represents the sum of tax currently payable and deferred tax. Tax is recognised in the statement of income, except to the extent that it relates to items recognised in other comprehensive income or directly in capital and reserves.
The companys liability for current tax is calculated using the tax rates and laws that have been enacted or substantively enacted at the reporting date.
Current and deferred tax assets and liabilities are not discounted.
Deferred taxation
Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the reporting date.
Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the reporting date that are expected to apply to the reversal of the timing difference.
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.
Current and deferred tax assets and liabilities are not discounted.
Intangible assets
Intangible assets (including purchased goodwill and patents) are amortised at rates calculated to write off the assets on a straight line basis over their estimated useful economic lives. Impairment of intangible assets is only reviewed where circumstances indicate that the carrying value of an asset may not be fully recoverable.
Tangible fixed assets
Tangible fixed assets, other than freehold land, are stated at cost or valuation less depreciation and any provision for impairment. Depreciation is provided at rates calculated to write off the cost or valuation of fixed assets, less their estimated residual value, over their expected useful lives on the following basis:
Provisions
Provisions are recognised when the company has a present obligation as a result of a past event which it is more probable than not will result in an outflow of economic benefits that can be reasonably estimated.
