The basic principle of impairment is that an asset may not be carried on the balance sheet above its
recoverable amount. Recoverable amount of a non-financial asset is defined as the higher of the asset’s fair
value less costs to sell and its value in use. Fair value less costs to sell is the amount obtainable from a sale
of an asset in an arm’s length transaction between knowledgeable, willing parties, less costs of disposal.
Value in use requires management to estimate the future cash flows to be derived from the asset, and
discount them using a pre-tax market rate that refects current assessments of the time value of money as
well as the risks specific to that asset.
