Non-current assets held for sale are classified as held for sale if their carrying amount will be recovered principally through a sale transaction rather than continuing use. Those assets are available for immediate sale in their present condition subject only to terms that are usual and customary for sales of such assets and the sale is highly probable. Non-current assets held for sale are measured at the lower of carrying amount and estimated fair value less costs to sell and are presented in a separate line in the statement of financial position if IFRS 5 requirements are met. Those assets are no longer depreciated. If fair value less costs to sell is less than its carrying amount, an impairment loss is recognised in the amount of the difference. In subsequent periods, if fair value less costs to sell increases the impairment loss is reversed up to the amount of losses previously recognised.
