Lesson objectives
By the end of this topic, you will be able to:
- Compute the effective interest in a sub-subsidiary
- Prepare goodwill workings for a vertical group
- Allocate post-acquisition profits between the group and the NCI
- Distinguish a vertical from a mixed group
- Explain the effect of the date each holding was acquired
Why this matters
CA23 consolidated one parent and one subsidiary. Real groups own subsidiaries through other subsidiaries, and the arithmetic of who owns what — and how much of each profit belongs to whom — is the substance of this paper.
Vertical groups
P owns 80% of S, and S owns 75% of T.
P therefore controls T, because it controls S and S controls T. Control passes down the chain, and T is consolidated in full.
But ownership does not pass down undiluted:
Effective interest of P in T = 80% × 75% = 60% NCI in T = 40%
That 40% is made up of the 25% direct outside holding in T, plus the 20% outside holding in S which indirectly owns part of T. The two are added together for consolidation purposes.
Control and ownership are different questions. P consolidates 100% of T because it controls it, while owning only 60% of it — and the 40% appears as non-controlling interest.
Goodwill in a vertical group
Goodwill is computed for each subsidiary separately.
Subsidiary T. Net assets at acquisition KES 60,000,000; the cost of S's investment in T was 52,000,000. Using the proportionate method:
| KES | |
|---|---|
| Cost of investment | 52,000,000 |
| NCI at 40% of net assets | 24,000,000 |
| Less net assets at acquisition | (60,000,000) |
| Goodwill in T | 16,000,000 |
Subsidiary S. Net assets at acquisition 90,000,000; cost 96,000,000; NCI 20%:
| KES | |
|---|---|
| Cost of investment | 96,000,000 |
| NCI at 20% | 18,000,000 |
| Less net assets at acquisition | (90,000,000) |
| Goodwill in S | 24,000,000 |
Total group goodwill = KES 40,000,000
Note the NCI percentage used for T is the effective 40%, not the direct 25%. Using 25% is the standard error and understates the NCI.
Post-acquisition profits
Each subsidiary's post-acquisition profit is split on the effective interest.
| Post-acq | Group share | NCI share | |
|---|---|---|---|
| S | 30,000,000 | 80% = 24,000,000 | 20% = 6,000,000 |
| T | 20,000,000 | 60% = 12,000,000 | 40% = 8,000,000 |
The T split reconciles to 20,000,000, which is the check to perform.
The date of acquisition matters
Where P acquired S first, and S later acquired T, T becomes part of the group on the date S bought T — because that is when P first controlled it.
Where S already owned T when P acquired S, T joins the group on the date P bought S, and T's pre-acquisition reserves are measured at that date.
The distinction changes which profits are pre-acquisition and which are post, and therefore changes both goodwill and group reserves. An examiner will give the dates precisely, and they are given for a reason.
:::checkpoint S acquired T two years before P acquired S. State the date from which T's profits are post-acquisition for the group, and explain the reasoning in one sentence. :::
Mixed groups
In a mixed group, the parent holds a direct interest in the sub-subsidiary as well as an indirect one — P owns 70% of S and 15% of T directly, while S owns 60% of T.
Effective interest in T = 15% direct + (70% × 60% indirect) = 15% + 42% = 57%
The principle is unchanged: add the direct holding to the indirect, and the remainder is NCI. Control still follows from the combined position.
Partial disposal without loss of control
P sells 30% of S, reducing its holding from 80% to 50% while retaining control.
Because control is retained, this is a transaction between owners, not a disposal. No gain or loss goes to profit or loss.
S's net assets are now 120,000,000, and the proceeds are 45,000,000:
| KES | |
|---|---|
| Increase in NCI (30% × 120,000,000) | 36,000,000 |
| Proceeds received | 45,000,000 |
| Credited directly to equity | 9,000,000 |
That treatment follows from the entity concept: the group has not disposed of anything, it has simply admitted other owners to a subsidiary it still controls. Recognising a profit would mean a group could report gains by selling shares in itself.
Where control IS lost, the treatment changes completely — a gain or loss goes to profit or loss, and any retained interest is remeasured to fair value. That is the next topic.
