(g) Impairment of property, plant and equipment
Property, plant and equipment are reviewed for impairment at least annually, or if there is any indication that the carrying amount
may
not
be recoverable. If any such indication is present, the recoverable amount of the asset is estimated in order to determine whether impairment exists. Where the asset does
not
generate cash flows that are independent from other assets, the Company estimates the recoverable amount of the cash generating unit to which the asset belongs.
An asset’s recoverable amount is the higher of fair value less costs of disposal and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value, using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which estimates of future cash flows have
not
been adjusted.
If the recoverable amount of an asset or cash generating unit is estimated to be less than its carrying amount, the carrying amount is reduced to the recoverable amount by way of recording an impairment charge to profit or loss. Where an impairment subsequently reverses, the carrying amount is increased to the revised estimate of recoverable amount but only to the extent that this does
not
exceed the carrying value that would have been determined if
no
impairment had previously been recognized.
