The cost of inventories is written down to net realisable value when there is an objective evidence that the cost of inventories may not be recoverable. The cost of inventories may not be recoverable if those inventories are aged and damaged, if they have become wholly or partially obsolete, or if their selling prices have declined. The cost of inventories may also not be recoverable if the estimated costs to be incurred to make the sales have increased. The amount written off in the consolidated statement of profit or loss is the difference between the carrying value and net realisable value of the inventories. In determining whether the inventories can be recoverable, significant judgement is required. In making this judgement, the Group evaluates, among other factors, the duration and extent by all means to which the amount will be recovered. During the year, certain inventories written down in prior years have been subsequently sold at prices higher than their then net realisable value. Provision regarding these inventories have been reversed. (e) Fair value of investment properties and property, plant and equipment measured at revalued amount The fair values of investment properties and property, plant and equipment measured at revalued amount are determined by using various valuation techniques. Details of the judgements and assumptions have been disclosed in Notes 16 and 17. (f) Fair value of a financial liability at fair value through profit or loss The fair value of a financial liability at fair value through profit or loss is determined by using valuation technique. Details of the judgements and assumptions have been disclosed in Note 30.
