107 Statutory Report 22 - 87 Financial Statements 88 - 229 Corporate Overview 01 - 21 Depreciation methods, estimated useful lives and residual value The charge in respect of periodic depreciation is derived after determining an estimate of expected useful life and the expected residual value of the assets at the end of its useful life. The lives are based on historical experience with similar assets as well as anticipation of future events, which may impact their lives. Depreciation is provided on a pro-rata basis on the straight-line method from the date of acquisition | installation till the date the assets are sold or disposed of: Asset category Estimated useful life Buildings 30 to 60 years Plant and equipment 1 6 to 20 years Vehicles 1 6 to 10 years Office equipment and furniture 5 to 10 years Roads 5 years Bearer plant 1 40 years 1 The useful lives have been determined based on technical evaluation done by the Management | experts, which are different from the useful life prescribed in Part C of Schedule II to the Act, in order to reflect the actual usage of the assets. The residual values are not more than 5% of the original cost of the asset. The residual values, useful lives and method of depreciation of property, plant and equipment are reviewed annually and adjusted prospectively, if appropriate. The carrying amount of an asset is written down immediately to its recoverable amount if the carrying amount of the asset is greater than its estimated recoverable amount. Land accounted under finance lease is amortised on a straight-line basis over the primary period of lease. Assets held under finance leases are depreciated over their expected useful lives on the same basis as own assets. However, when there is no reasonable certainty that ownership will be obtained by the end of the lease term, assets are depreciated over the shorter of the lease term and their useful lives. i) Intangible assets Computer software includes enterprise resource planning application and other costs relating to such software that provide significant future economic benefits. These costs comprise license fees and cost of system integration services. Development expenditure qualifying as an intangible asset, if any, is capitalised, to be amortised over the economic life of the product | patent. Computer software cost is amortised over a period of three years using the straight-line method. j) Investment properties Property that is held for long-term rental yields or for capital appreciation or both, and that is not in use by the Company, is classified as investment property. Land held for a currently undetermined future use is also classified as an investment property. Investment property is measured at its acquisition cost, including related transaction costs and where applicable, borrowing costs. k) Impairment The carrying amount of assets are reviewed at each Standalone Balance Sheet date to assess if there is any indication of impairment based on internal | external factors. An impairment loss on such assessment is recognised wherever the carrying amount of an asset exceeds its recoverable amount. The recoverable amount of the assets is net selling price or value in use, whichever is higher. While assessing value in use, the estimated future cash flows are discounted to the present value by using weighted average cost of capital. A previously recognised impairment loss is further provided or reversed depending on changes in the circumstances and to the extent that carrying amount of the assets does not exceed the carrying amount that will be determined if no impairment loss had previously been recognised. l) Cash and cash equivalents Cash and cash equivalents include cash in hand, demand deposits with bank and other short-term (three months or less from the date of acquisition), highly liquid investments that are readily convertible into cash and which are subject to an insignificant risk of changes in value.
