Basis of preparation The financial statements have been prepared on the going concern basis and in accordance with the historical cost convention except for certain properties and financial instruments that are measured at revalued amounts or fair values, as explained in the accounting policies below. Historical cost is generally based on the fair value of the consideration given in exchange for assets. Trade and other debtors Trade and other debtors are initially recognised at fair value and thereafter stated at amortised cost using the effective interest method less impairment losses for bad and doubtful debts except where the effect of discounting would be immaterial. In such cases the receivables are stated at cost less impairment losses for bad and doubtful debts. Cash and cash equivalents Cash and cash equivalents comprise cash at bank and in hand, demand deposits with banks and other short-term highly liquid investments with original maturities of three months or less and bank overdrafts. In the Balance Sheet bank overdrafts are shown within Creditors. Trade and other creditors Trade and other creditors are initially recognised at fair value and thereafter stated at amortised cost using the effective interest rate method, unless the effect of discounting would be immaterial, in which case they are stated at cost. Employee benefits The company operates a defined contribution pension scheme. The assets of the scheme are held separately from those of the company in an independently administered fund. The company also operates a defined benefit pension scheme for its employees providing benefits based on final pensionable pay. The assets of this scheme are also held separately from those of the company, being invested with pension fund managers. Taxation and deferred taxation Current tax represents the amount expected to be paid or recovered in respect of taxable profits for the financial period and is calculated using the tax rates and laws that have been enacted or substantially enacted at the Balance Sheet date. Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date where transactions or events have occurred at that date that will result in an obligation to pay more tax in the future, or a right to pay less tax in the future. Timing differences are temporary differences between the company's taxable profits and its results as stated in the financial statements. Deferred tax is measured on an undiscounted basis at the tax rates that are anticipated to apply in the periods in which the timing differences are expected to reverse, based on tax rates and laws that have been enacted or substantively enacted by the Balance Sheet date. Foreign currencies Monetary assets and liabilities denominated in foreign currencies are translated at the rates of exchange ruling at the Balance Sheet date. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated at the rates of exchange ruling at the date of the transaction. Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. The resulting exchange differences are dealt with in the Profit and Loss Account. Ordinary share capital The ordinary share capital of the company is presented as equity.
