Notional Goodwill

I’m not sir (not for the purposes of open tuition anyway!) but I’ll have a go at answering.

We need to compare the subsidiary value with the recoverable amount to begin with, to determine if and how much impairment there is. So we have to gross up the NCI with their notional goodwill, for comparison purposes.

if im not mistaken, notional goodwill came once right in past year question between 2012-2015 (i forgot exactly which one), but i remember that we calculate that if the entity use partial goodwill method, and the impairment reach not only goodwill, but other asset.

so it is like, if my goodwill (partial) is 100 and my share in subsidiary is 80%, then to calculate impairment, I grossed up my goodwill first, 100x(100%/80%) = 125. Then I add it to fair value of net asset at date of reporting, compare it with recoverable amount. Assume the impairment loss is 200.

To find out the allocation of impairment loss in the asset, that’s when we deduct notional goodwill of NCI, which is the grossed up amount before, 125-100=25. After that, 200-25 = 175. This 175 is allocated to parent goodwill, reduce it fully to 0 (100-100), then the rest of 75 is allocated to (let’s say) PPE. And for this PPE, we separate further 80%x75=60 to parent and 20%x75=15 to NCI.

So, in CSOFP later
Goodwill: 100-100
PPE: xxx-75
Retained earning: yyy-100-60
NCI: zzz-15

I might be wrong, please check and correct me
