1. Impairment of assetsImpairment is determined by comparing the carrying amount of the asset with its recoverable amount. This is the higher of its fair value less costs to sell and its value in use.The main accounting issues to consider are therefore as follows (a) H ow is it possible to identify when an impairment loss may haveoccurred?(b) H ow should the recoverable amount of the asset be measured?(c) How should an “impairment loss” be reported in the accounts?1.1Identifying a potentially impaired assetAn entity should assess at the end of each reporting period whether there are any indications of impairment to any assets. The concept of materiality applies, and only material impairment needs to be identified.If there are indications of possible impairment, the entity is required to make a formal estimate of the recoverable amount of the assets concerned.(a) E xternal sources of information(ⅰ) A fall in the asset’s market value that is more significant than would normally be expected from passage of time over normal use (ⅱ)A significant change in the technological, market ,legal or economic environment of business in which the assets areemployed.(ⅲ)An increase in market interest rates or market rates of return on investments likely to affect the discount rate used in calculating value in use.(ⅳ)The carrying amount of the entity’s net assets being more than its market capitalization.(b) I nternal sources of information: evidence of obsolescence orphysical damage, adverse changes in the use to which the asset is put, or the asset’s economic performanceEven if there are no indications of impairment, the following assets must always be tested for impairment annually.(a) An intangible asset with an indefinite useful life(b) Goodwill acquired in a business combination1.2Measuring the recoverable amount of the assetThe recoverable amount of an asset should be measured as the higher value of:(a) the asset’s fair value less costs to sell; and(b) its value in useThe value in use of an asset is measured as the present value of estimated future cash flows (inflows minus outflows) generated by the asset, including its estimated net disposal value (if any) at the end of its expected useful life.1.3Recognition and measurement of an impairment lossIf the recoverable amount of an asset is lower than the carrying amount, the carrying amount should be reduced by the difference (ie the impairment loss) which should be charged as an expense in profit or loss.2. Cash generating unitsWhen it is not possible to calculate the recoverable amount of a single asset, then that of its cash generating unit should be measured instead.A cash-generating unit is the smallest identifiable group of assets for which independent cash flows can be identified and measured.3. Goodwill and the impairment of assetsAllocating goodwill to cash-generating unitsGoodwill acquired in a business combination does not generate cash flows independent of other assets. It must be allocated to each of the acquired’s cash-generating units( or groups of cash-generating units) that are expected to benefit from the synergies of the combination.allocation of impairment loss(a) First, to any assets that are obviously damaged or destroyed(b) Next, to the goodwill allocated to the cash generating unit (C) Then to all other assets in the cash-generating unit, on a prorata basisExample: A cash-generating unit comprises the following:$mBuilding 30Plant and equipment 6Goodwill 1066Following a recession, an impairment review has estimated the recoverable amount of the cash-generating unit to be $50m.How do we allocate the impairment loss?Carrying amount Impairment loss Carrying amountpost-impairment$m $m $m Building 30 (5) 25Plant and equipment 6 (1) 5 Goodwill 10 (10) ---66 (16) 50Example2: impairment lossA company has acquired another business for $4.5: tangible assets are valued at $4.0m and goodwill at $0.5m.An asset with a carrying value of $1m is destroyed in a terrorist attack. The asset was not insured. The loss of the asset, without insurance, has prompted the company to assess whether there has been an impairment of assets in the acquired business and what the amount of any such loss is.The recoverable amount of the business( a single cash generating unit) is measured as $3.1m.SolutionThere has been an impairment loss of $1.4m ($4.5-$3.1).The impairment loss will be recognized in profit or loss. The loss will be allocated between the assets in the cash generating unit as follows.(a) A loss of $1 can be attributed directly to the uninsured asset thathas been destroyed.(b) The remaining loss of $0.4m should be allocated to goodwill The carrying value of the assets will now be $3m for tangible assets and $0.1m for goodwill.Reversal of an impairment loss(a) The reversal of the impairment loss should be recognizedimmediately as income in profit or loss.(b) The carrying amount of the asset should be increased to itsnew recoverable amountAn exception to this rule is for goodwill. An impairment loss for goodwill should not be reversed in a subsequent period.QuestionA cash generating unit comprising a factory, plant and equipment etc and associated purchased goodwill becomes impaired because the product it makes is overtaken by a technologically more advanced model produced by a competitor. The recoverable amount of the cash generating unit falls to $60,resulting in an impairment loss of $80m,allocated as follows.Carrying amounts carrying amountsBefore impairment after impairment$m $mGoodwill 40 ---Patent (with no market value) 20 ---Tangible non-current assets 80 60Total 140 60After three years, the entity makes a technological breakthrough of its own, and the recoverable amount of the cash generating unit increases to $90m.The carrying amount of the tangible non-currentassets had the impairment not occurred would have been $70m. RequiredCalculate the reversal of the impairment lossAnswerThe reversal of the impairment loss is recognized to the extent that it increases the carrying amount of the tangible non-current assets to what it would have been had the impairment not taken place, ie a reversal of the impairment loss of $10m is recognized and the tangible non-current assets written back to $70m.Reversal of the impairment is not recognized in relation to the goodwill and patent because the effect of the external event that caused the original impairment has not reversed-the original product is still overtaken by a more advanced model.。
