Investments Investments in subsidiaries, associates and goodwill are measured at cost less any accumulated impairment losses. Unlisted investments are measured at fair value unless the value cannot be measured reliably, in which case they are measured at cost less any accumulated impairment losses. Changes in fair value are included in the profit and loss account. Consolidation The company and its subsidiary comprise a small sized group. The company has therefore taken advantage of the exemption provided by the Companies Act 2006 not to prepare group accounts. Debtors Short term debtors are measured at transaction price, less any impairment losses for bad and doubtful debts. Loans and other financial assets are initially recognised at transaction price including any transaction costs and subsequently measured at amortised cost determined using the effective interest method, less any impairment losses for bad and doubtful debts. Creditors Short term creditors are measured at transaction 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. Provisions Provisions are recognised when there is an obligation at the reporting date as a result of a past event, it is probable that economic benefit will be transferred to settle the obligation and the amount of the obligation can be estimated reliably. Taxation A current tax liability is recognised for the tax payable on the taxable profit of the current and past periods. A current tax asset is recognised in respect of a tax loss that can be carried back to recover tax paid in a previous period. 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.
