Leasing Rentals payable under operating lease are charged to the Statement of Income and Retained Earnings on a straight line basis over the period of the lease. Debtors Short term debtors are measured at transaction price, less any impairment. Cash and cash equivalents Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value. Creditors Short term creditors are measured at the transaction price. Financial instruments A financial asset or a financial liability is recognised only when the entity becomes a party to the contractual provisions of the instrument. Basic financial instruments, such as trade debtors, cash and trade creditors, are initially recognised at the transaction price, unless the arrangement constitutes a financing transaction, where it is recognised at the present value of the future payments discounted at a market rate of interest for a similar debt instrument. Debt instruments are subsequently measured at amortised cost. Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An equity instrument is any contract that evidences a residual interest in the assets of the entity after deducting all of its financial liabilities. Where the contractual obligations of financial instruments (including share capital) are equivalent to a similar debt instrument, those financial instruments are classed as financial liabilities. Financial liabilities are presented as such in the balance sheet. Finance costs and gains or losses relating to financial liabilities are included in the profit and loss account. Finance costs are calculated so as to produce a constant rate of return on the outstanding liability. Where the contractual terms of share capital do not have any terms meeting the definition of a financial liability then this is classed as an equity instrument. Dividends and distributions relating to equity instruments are debited directly to equity.
