(f) Impairment of assets
For the purposes of assessing impairment, assets are grouped in cash-generating units (“CGUs”), which represent the lowest levels for which there are separately identifiable cash inflows generated by those assets. The Corporation reviews, at each balance sheet date, whether events or circumstances have occurred to indicate that the carrying amounts of its long-lived assets with finite useful lives may be less than their recoverable amounts. Goodwill, intangible assets having an indefinite useful life, and intangible assets not yet available for use are tested for impairment each financial year, as well as whenever there is an indication that the carrying amount of the asset, or the CGU to which an asset has been allocated, exceeds its recoverable amount. The recoverable amount is the higher of the fair value less costs of disposal and the value in use of the asset or the CGU. Fair value less costs of disposal represents the amount an entity could obtain at the valuation date from the asset’s disposal in an arm’s length transaction between knowledgeable, willing parties, after deducting the costs of disposal. The value in use represents the present value of the future cash flows expected to be derived from the asset or the CGU.
An impairment loss is recognized in the amount by which the carrying amount of an asset or a CGU exceeds its recoverable amount. When the recoverable amount of a CGU to which goodwill has been allocated is lower than the CGU’s carrying amount, the related goodwill is first impaired. Any excess amount of impairment is recognized and attributed to assets in the CGU, prorated to the carrying amount of each asset in the CGU.
An impairment loss recognized in prior periods for long-lived assets with finite useful lives and intangible assets having an indefinite useful life, other than goodwill, can be reversed through the consolidated statement of income to the extent that the resulting carrying value does not exceed the carrying value that would have been the result if no impairment loss had previously been recognized.
