A non-controlling interest is the equity in a subsidiary that is not attributable, directly or indirectly, to the parent. Older textbooks often use the term minority interest, but current IFRS terminology is non-controlling interest, or NCI.
NCI affects acquisition accounting, goodwill, consolidated profit, equity and later ownership changes. This guide follows the logic of IFRS 3 and IFRS 10 and shows how to keep the calculation connected to the consolidation workings.
Identify the ownership interest at the acquisition date
Start with the parent’s direct and indirect ownership percentages and the rights attached to the shares. Control, not a simple percentage threshold, determines whether the investee is consolidated. Once control exists, the subsidiary is consolidated in full and the portion belonging to other owners is presented as NCI.
Check different share classes, options, potential voting rights and agreements that affect control. The NCI percentage used for profit allocation may differ from the voting percentage if rights are not proportionate.
Choose the permitted acquisition-date measurement
For each business combination, IFRS 3 permits eligible NCI to be measured either at fair value or at the proportionate share of the acquiree’s identifiable net assets. The choice affects recognised goodwill.
Fair-value measurement produces full goodwill, including the portion attributable to NCI. Proportionate measurement produces partial goodwill. Record the method in the acquisition memo and apply it consistently to the calculation.
Calculate goodwill and bargain purchase
Goodwill broadly equals consideration transferred plus the chosen NCI measurement plus any previously held interest, less the fair value of identifiable net assets acquired. Acquisition-date fair value adjustments must be included before calculating NCI and goodwill.
If the resulting amount is negative, reassess the identification and measurement of assets, liabilities, consideration and NCI before recognising a bargain-purchase gain.
Allocate post-acquisition profit and other comprehensive income
After acquisition, the subsidiary’s profit or loss and other comprehensive income are allocated between owners of the parent and NCI. The allocation is based on the relevant ownership interests even if this causes NCI to have a deficit balance.
Use post-acquisition figures after consolidation adjustments such as additional depreciation on fair value uplifts, impairment, intragroup profit elimination and aligned accounting policies.
Present NCI in consolidated equity
NCI is presented within equity, separately from equity attributable to owners of the parent. It is not a liability merely because the parent does not own it.
The closing balance normally starts with acquisition-date NCI, adds the NCI share of post-acquisition comprehensive income, subtracts dividends and adjusts for ownership transactions and other relevant movements.
Account for dividends and intragroup items
Dividends paid by the subsidiary to NCI reduce the NCI balance and are financing cash flows in the consolidated cash-flow statement when paid. Dividends to the parent are eliminated on consolidation.
Intragroup balances and transactions are eliminated in full. Unrealised profit adjustments are allocated according to whether the seller is the parent or subsidiary and the specific facts of the transaction.
Handle ownership changes without loss of control
When the parent buys or sells an additional interest but retains control, the transaction is accounted for within equity. No new goodwill or profit or loss is recognised. The carrying amounts of controlling and non-controlling interests are adjusted, and the difference from consideration is recognised in parent equity.
This treatment reflects a transaction between owners acting in their capacity as owners.
Handle loss of control separately
Loss of control is a disposal event. The parent derecognises the subsidiary’s assets, liabilities and NCI, recognises consideration and any retained interest at fair value, reclassifies relevant reserves and records the resulting gain or loss.
Do not apply the equity-transaction method when control is lost. The date of loss of control and fair value evidence need careful support.
Worked NCI movement example
Assume a parent acquires 80% of a subsidiary whose identifiable net assets at acquisition are $500,000. NCI is measured proportionately at $100,000. During the next year, adjusted post-acquisition profit is $60,000 and the subsidiary pays $10,000 of dividends to NCI.
The closing NCI is $100,000 plus 20% of $60,000, less $10,000, giving $102,000. If fair-value adjustments create extra depreciation, use profit after that adjustment rather than the subsidiary’s unadjusted profit.
Reconcile NCI to the group reporting package
Maintain an NCI roll-forward for each subsidiary showing opening balance, acquisition or disposal effects, profit, other comprehensive income, dividends, ownership changes, foreign exchange and closing balance. The total should agree to consolidated equity and related notes.
Compare the working with the subsidiary’s adjusted reporting package and the group ownership register. This is especially important when there are multiple classes of shares, indirect holdings or mid-year acquisitions.
Consolidation checklist and common errors
- Confirm control before calculating ownership percentages.
- Document the NCI measurement option at acquisition.
- Include fair-value adjustments in net assets.
- Allocate adjusted post-acquisition profit and OCI.
- Deduct dividends paid to NCI.
- Separate equity transactions from loss-of-control events.
- Reconcile the NCI movement to consolidated equity.
Common errors include treating NCI as a liability, using subsidiary profit before consolidation adjustments, recognising goodwill on later ownership purchases and ignoring indirect ownership.
