l) Impairment of non-financial assets
Intangible assets that are subject to depreciation and amortization are reviewed for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized when the carrying amount of an asset or cash generating unit exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less cost of disposal and its value in use. For the purpose of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash inflows (cash generating units).
