NOTES TO THE FINANCIAL STATEMENTS Cont’d 2. Significant accounting policies cont’d (d) Property, plant and equipment cont’d (ii) Subsequent costs The cost of replacing a component of an item of property, plant and equipment is recognised in the carrying amount of the item if it is probable that the future economic benefits embodied within the component will flow to the Group or the Company, and its cost can be measured reliably. The carrying amount of the replaced component is derecognised to profit or loss. The costs of the day-to-day servicing of property, plant and equipment are recognised in profit or loss as incurred. (iii) Depreciation Depreciation is based on the cost of an asset less its residual value. Significant components of individual assets are assessed, and if a component has a useful life that is different from the remainder of that asset, then that component is depreciated separately. Depreciation is recognised in profit or loss on a straight-line basis over the estimated useful lives of each component of an item of property, plant and equipment from the date that they are available for use. Freehold land is not depreciated. Capital work-in-progress are not depreciated until the assets are ready for their intended use. The estimated useful lives for the current and comparative periods are as follows: • mine, conveying, refining and port facilities 4 - 65 years • buildings and renovation 10 - 50 years • plant and machinery 5 - 25 years • office equipment 10 years • motor vehicles 5 - 10 years • furniture and fittings 10 years • moulds and dies 3 - 6 years Depreciation methods, useful lives and residual values are reviewed at the end of the reporting period, and adjusted as appropriate. (e) Leases (i) Definition of a lease A contract is, or contains, a lease if the contract conveys a right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Group assesses whether: • the contract involves the use of an identified asset – this may be specified explicitly or implicitly, and should be physically distinct or represent substantially all of the capacity of a physically distinct asset. If the supplier has a substantive substitution right, then the asset is not identified; • the customer has the right to obtain substantially all of the economic benefits from use of the asset throughout the period of use; and • the customer has the right to direct the use of the asset. The customer has this right when it has the decision-making rights that are most relevant to changing how and for what purpose the asset is used. In rare cases where the decision about how and for what purpose the asset is used is predetermined, the customer has the right to direct the use of the asset if either the customer has the right to operate the asset; or the customer designed the asset in a way that predetermines how and for what purpose it will be used.
