124 FINANCIAL STATEMENTS ANNUAL REPORT 2020 3. SIGNIFICANT ACCOUNTING POLICIES (CONT’D) (i) Tax expense (Cont’d) For the purposes of measuring deferred tax liabilities and deferred tax assets for investment properties that are measured using the fair value model, the carrying amounts of such properties are presumed to be recovered entirely through sale, unless the presumption is rebutted. The presumption is rebutted when the investment property is depreciable and is held within a business model whose objective is to consume substantially all of the economic benefits embodied in the investment property over time, rather than through sale. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Group intends to settle the current tax assets and liabilities on a net basis. (j) Property, plant and equipment (i) Recognition and measurement All items of property, plant and equipment are initially recorded at cost. Subsequent to recognition, property, plant and equipment, except for long-term leasehold land, freehold land and buildings, are stated at cost less accumulated depreciation and impairment loss, if any. Freehold land are stated at valuation, which is the fair value at the date of valuation, less impairment loss, if any. Long-term leasehold land and buildings are stated at valuation, which is the fair value at the date of the valuation, less accumulated depreciation and impairment loss, if any. The Group revalues its land and building every five years from the last date of valuation or at shorter intervals whenever the fair value of the said assets is expected to differ substantially from its carrying amounts. Surplus arising from revaluation are transferred to revaluation reserve. Any deficits are offset against the previously recognised revaluation surplus to the extent of a previous increase for the same property and the balance is thereafter recognised in profit or loss. Upon disposal or retirement of an asset, any unutilised revaluation reserve relating to the particular asset is transferred to retained earnings. Cost includes expenditures that are directly attributable to the acquisition of the asset. The cost of self-constructed assets includes the cost of materials and direct labour, any other costs directly attributable to bringing the asset to working condition for its intended use, and the costs of dismantling and removing the items and restoring the site on which they are located. Purchased software that is integral to the functionality of the related equipment is capitalised as part of that equipment. When significant parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment. An item of property, plant and equipment is derecognised upon disposal or when no future economic benefits are expected from its use or disposal. The difference between the net disposal proceeds, if any, and the net carrying amount is recognised in profit or loss.
