Residual value represents the estimated amount which would currently be obtained from disposal of an asset, after deducting estimated costs of disposal, if the asset were already of the age and condition expected at the end of its useful life.
Impairment of assets
Assets, other than those measured at fair value, are assessed for indicators of impairment at each Statement of Financial Position date. If there is objective evidence of impairment, an impairment loss is recognised in the Statement of Income and Retained Earnings as described below.
At each Statement of Financial Position date, the Company reviews its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss.
If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). The recoverable amount of the asset is the higher of its fair value less costs to sell and its value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cashflows have not been adjusted.
Where it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs. An impairment loss is recognised immediately in the Statement of Income and Retained Earnings, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease.
