The assets’ residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.
Repairs and maintenance costs are charged to profit or loss during the period in which they are incurred.
Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in profit or loss.
At each reporting date the company assesses whether there is any indication of impairment. If such indication exists, the recoverable amount of the asset is determined, which is the higher of its fair value less costs to sell and its value in use. Any impairment loss is recognised immediately as an expense within the profit or loss.
Property Valuation Model
Freehold land and buildings are carried at revalued amounts, being fair value at the date of revaluation less subsequent depreciation on buildings. Fair value is based on market value, usually determined by an independent, professionally qualified valuer. Revaluations are performed with sufficient regularity such that the carrying amount does not differ materially from fair value at the reporting date.
Increases in carrying amount arising on revaluation are recognised in other comprehensive income and accumulated in equity in the revaluation reserve, except to the extent that they reverse a revaluation decrease of the same asset previously recognised in profit or loss. Decreases in carrying amount are recognised in profit or loss, except to the extent that they reverse a previous revaluation surplus on the same asset, in which case the decrease is recognised in other comprehensive income and reduces the revaluation reserve.
On subsequent disposal of a revalued property, the balance on the revaluation reserve relating to that property is transferred directly to retained earnings.
Land is not depreciated. Buildings are depreciated to their estimated residual values on a straight-line basis over their estimated useful lives.
