| Investments in subsidiaries, associates and joint ventures are measured at cost less any accumulated impairment losses. Listed investments are measured at fair value where the difference between cost and fair value is material. 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.
Valuation of financial instruments policy
Basic financial assets are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of the future receipts discounted at a market rate of interest. Financial assets classified as receivable within one year are not amortised.
Basic financial liabilities are initially recognised at transaction price unless the arrangement constitutes a financing transaction, where the debt instrument is measured at the present value of the future payments discounted at a market rate of interest. Financial liabilities classified as payable within one year are not amortised.
Debt instruments are subsequently carried at amortised cost, using the effective interest rate method. |
