A class of property, plant and equipment is a grouping of assets of a similar nature and use in an entity’s operations. The following are examples of separate classes: (a) land; (b) land and buildings; (c) machinery; (d) ships; (e) aircraft; (f) motor vehicles; (g) furniture and fixtures; and (h) office equipment.
38 The items within a class of property, plant and equipment are revalued simultaneously to avoid selective revaluation of assets and the reporting of amounts in the financial statements that are a mixture of costs and values as at different dates. However, a class of assets may be revalued on a rolling basis provided EC staff consolidated version as of 16 September 2009, EN – EU IAS 16 FOR INFORMATION PURPOSES ONLY 7 revaluation of the class of assets is completed within a short period and provided the revaluations are kept up to date.
39 If an asset’s carrying amount is increased as a result of a revaluation, the increase shall be recognised in other comprehensive income and accumulated in equity under the heading of revaluation surplus. However, the increase shall be recognised in profit or loss to the extent that it reverses a revaluation decrease of the same asset previously recognised in profit or loss.
40 If an asset’s carrying amount is decreased as a result of a revaluation, the decrease shall be recognised in profit or loss. However, the decrease shall be recognised in other comprehensive income to the extent of any credit balance existing in the revaluation surplus in respect of that asset. The decrease recognized in other comprehensive income reduces the amount accumulated in equity under the heading of revaluation surplus.
