Key Sources of Estimation Uncertainty (cont’d)
Impairment of investment in subsidiaries
The Group and the Company carried out the impairment test based on a variety of estimation including the value-in-use of the cash generating unit. Estimating the value-in-use requires the Group and the Company to make an estimate of the expected future cash flows from the cash generating unit and also to choose a suitable discount rate in order to calculate the present value of those cash flows.
The Group is subject to income taxes in numerous jurisdictions. Significant judgement is required in determining the capital allowances and deductibility of certain expenses during the estimation of the provision for income taxes. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the income tax and deferred income tax provisions in the period in which such determination is made.
Allowance for doubtful debts
The Group makes allowances for doubtful debts based on an assessment of the recoverability of receivables. Allowances are applied to receivables where events or changes in circumstances indicate that the carrying amounts may not be recoverable. Management specifically analysed historical bad debts, customer concentrations, customer creditworthiness, current economic trends and changes in customer payment terms when making a judgement to evaluate the adequacy of the allowance of doubtful debts of receivables. Where the expectation is different from the original estimate, such difference will impact the carrying value of receivables.
Where it is not probable that an outflow of economic benefits will be required, or the amount cannot be estimated reliably, the obligation is disclosed as a contingent liability, unless the probability of outflow of economic benefits is remote. Possible obligations, whose existence will only be confirmed by the occurrence or non-occurrence of one or more future events, are also disclosed as contingent liabilities unless the probability of outflow of economic benefits is remote.
The determination of treatment of contingent liabilities is based on management’s view of the expected outcome of the contingencies for matters in the ordinary course of the business.
Non-current Assets Held for Sale
Non-current assets held for sale are in respect of properties which are pending disposal and in line with the rationalisation plan of the Group. These assets are actively marketed for sale. The Group expects the sale of such assets to be completed within the next 12 months. However, the Group has continued to classify certain assets as non-current assets held for sale even though the sale has not been completed within one year as the delay is caused by circumstances beyond the Group's control and the Group remains committed to its plan to sell the assets.
