as per AS - 28 If the recoverable amount of an asset is less than its carrying amount, the carrying amount of the asset should be reduced to its recoverable amount. That reduction is an impairment loss.
An impairment loss should be recognised as an expense in the statement of profit and loss immediately, unless the asset is carried at revalued amount in accordance with another Accounting Standard [see Accounting Standard (AS) 10, Accounting for Fixed Assets], in which case any impairment loss of a revalued asset should be treated as a revaluation decrease under that Accounting Standard.
An impairment loss on a revalued asset is recognised as an expense in the statement of profit and loss. However, an impairment loss on a revalued asset is recognised directly against any revaluation surplus for the asset to the extent that the impairment loss does not exceed the amount held in the revaluation surplus for that same asset.
When the amount estimated for an impairment loss is greater than the carrying amount of the asset to which it relates, an enterprise should recognise a liability if, and only if, that is required by another Accounting Standard.
After the recognition of an impairment loss, the depreciation (amortisation) charge for the asset should be adjusted in future periods to allocate the asset’s revised carrying amount, less its residual value (if any), on a systematic basis over its remaining useful life.
If an impairment loss is recognised, any related deferred tax assets or liabilities are determined under Accounting Standard (AS) 22, Accounting for Taxes on Income (see Illustration 3 given in the Illustrations attached to the Standard).
