编为大家吐血整理了ACCA P2考试知识点：Impairment of goodwill之Part B!

　　4. Goodwill and impairment

　　The asset of goodwill does not exist in a vacuum; rather, it arises in the group accounts because it is not separable from the net assets of the subsidiary that have just been acquired.

　　The impairment review of goodwill therefore takes place at the level of a cash-generating unit, that is to say a collection of assets that together create an independent stream of cash. The cash-generating unit will normally be assumed to be the subsidiary. In this way, when conducting the impairment review, the carrying value will be that of the net assets and the goodwill of the subsidiary compared with the recoverable amount of the subsidiary. When looking to assign the impairment loss to particular assets within the cash generating unit, unless there is an asset that is specifically impaired, it is goodwill that is written off first, with any further balance being assigned on a pro rata basis.

　　The goodwill arising on the acquisition of a subsidiary is subject to an annual impairment review. This requirement ensures that the asset of goodwill is not being overstated in the group accounts. Goodwill is a peculiar asset in that it cannot be revalued so any impairment loss will automatically be charged against income. Goodwill is not deemed to be systematically consumed or worn out thus there is no requirement for a systematic amortisation.

　　5. Proportionate goodwill and the impairment review

　　When goodwill has been calculated on a proportionate basis then for the purposes of conducting the impairment review it is necessary to gross up goodwill so that in the impairment review goodwill will include an unrecognised notional goodwill attributable to the NCI.

　　Any impairment loss that arises is first allocated against the total of recognised and unrecognised goodwill in the normal proportions that the parent and NCI share profits and losses.

　　Any amounts written off against the notional goodwill will not affect the consolidated financial statements and NCI. Any amounts written off against the recognised goodwill will be attributable to the parent only, without affecting the NCI.

　　If the total amount of impairment loss exceeds the amount allocated against recognised and notional goodwill, the excess will be allocated against the other assets on a pro rata basis. This further loss will be shared between the parent and the NCI in the normal proportion that they share profits and losses.
