Notes to the Financial Statements Other Assets Other assets are stated at cost less accumulated depreciation and any provision for impairment. Depreciation is provided on a straight line basis to write off the cost less estimated residual value over the estimated useful lives of the assets, with the exception of land which is not depreciated. The estimated useful lives of assets are as follows: Boreholes Buildings and Service Reservoirs Fixed Plant Water Meters Office Equipment Mobile Plant Motor Vehicles 100 years Up to 80 years Up to 30 years Up to 20 years Up to 20 years Up to 20 years 3–7 years (g) Capital Contributions Capital contributions are treated as deferred income and amortised over the estimated useful lives of the assets concerned, except in the case of contributions towards the cost of infrastructure assets, which are not amortised. This departure from the requirements of the Companies Act 2006 is, in the opinion of the Directors consistent with industry accounting practice and is necessary for the financial statements to show a true and fair view as it is not possible to amortise contributions to the profit and loss account over the lives of the fixed assets concerned, as infrastructure assets do not have determinable finite lives as they are maintained in perpetuity. (h) Leased Assets Assets financed by leasing and hire-purchase arrangements which transfer substantially all the risks and rewards of ownership to the Group are included in tangible fixed assets, and the net obligation to pay future rentals is included as borrowings within creditors. Rentals are apportioned between finance charges and a reduction of the outstanding liability for future rentals so as to produce a constant charge to the profit and loss account 62 based upon the capital outstanding. Operating lease rentals are charged to the profit and loss account on a straight line basis. (i) Investments Investments held as fixed assets are stated at cost less amounts written off and any provision for impairment. In accordance with Section 611 of the Companies Act 2006, the cost of shares acquired from a fellow group undertaking by way of a share for share exchange are recorded at the higher of the nominal value of the shares issued as consideration and the carrying value of the investment in the transferring company. (j) Stocks Stocks are valued at the lower of cost and net realisable value. Cost includes an appropriate element of overheads. Provision is made for obsolete, slow moving or defective items where appropriate. (k) Foreign Currency Transactions in foreign currencies are recorded at the rate of exchange at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are reported at the rates of exchange prevailing at that date. The results of overseas operations are translated at the average rates of exchange during the year and their balance sheets at the rates prevailing at the balance sheet date. Exchange differences arising on translation of the opening net assets and results of overseas operations and on foreign currency borrowings, to the extent that they hedge the Group’s investment in such operations, are reported in the consolidated statement of total recognised gains and losses. All other exchange differences are included in the profit and loss account. (l) Pensions The profit and loss charge in respect of defined benefit pension schemes represents: - the increase in the present value of scheme liabilities expected to arise from employee service in the year. This is charged against operating profit. - the difference between the unwinding of the discount on scheme liabilities and the expected return on scheme assets. This is charged or credited within finance charges (net). Actuarial gains and losses are charged or credited directly to t he consolidated statement of total recognised gains and losses net of deferred tax. The defined benefit schemes’ liabilities, valued using the projected unit method and the fair value of schemes’ assets, are recognised in the consolidated balance sheet (net of deferred tax) as a net retirement benefit obligation or surplus. In the case of a surplus, this is recognised in the consolidated balance sheet to the extent that the Group is legally entitled to recover the surplus in the future either through reduced contributions to schemes, or refunds from schemes. In respect of the Group defined contribution schemes the amounts charged to the profit and loss account are the contributions payable in the year. (m) Research and Development Research and development expenditure is charged to the profit and loss account in the year in which it is incurred.
