IFRS 10 Loss of Control — Core Rule
When a parent loses control of a subsidiary, it must derecognise the subsidiary's net assets, recognise any retained interest at fair value, and record the resulting gain or loss immediately in profit or loss. This is a fundamental accounting event — not an equity transaction (IFRS 10.25). The entire gain or loss flows through the income statement on the date control is lost, making the measurement of the retained interest and the consideration received critically important.
How IFRS 10 Loss of Control Works
On the date control is lost, the parent works through a structured sequence of entries (IFRS 10.B99):
- Derecognise all assets (including goodwill) and liabilities of the former subsidiary at their carrying amounts
- Derecognise the carrying amount of any non-controlling interests in the former subsidiary, including any related other comprehensive income balances
- Recognise the fair value of any consideration received from the transaction
- Recognise the fair value of any retained investment in the former subsidiary at the date control is lost
- Reclassify to profit or loss any amounts previously recognised in other comprehensive income that would be reclassified on disposal
- Recognise the resulting gain or loss in profit or loss attributable to the former parent
The retained interest is remeasured to fair value at the date of loss of control, and that remeasurement forms the starting cost basis for subsequent accounting under the relevant IFRS — for example, as an associate under IAS 28 or a financial asset under IFRS 9 (IFRS 10.25).
Multiple arrangements: A parent might dispose of its interest across two or more separate transactions. Where the arrangements are linked, they must be accounted for as a single transaction. IFRS 10 guidance sets out indicators that suggest multiple arrangements should be treated as one — for instance, where a below-market disposal is compensated by a subsequent above-market disposal (IFRS 10.B97).
Contrast with partial disposals that do not result in loss of control: Where a parent reduces its ownership interest but retains control, no gain or loss is recognised. Those transactions are treated as equity transactions between the parent and non-controlling interest holders (IFRS 10.23). The profit-or-loss treatment is strictly reserved for the moment control actually ceases.
IFRS 10 Loss of Control — Common Pitfalls
- Incorrect date identification: The gain or loss must be recognised on the specific date control is lost — not when legal completion occurs if that differs from the date the parent ceases to direct relevant activities.
- Forgetting cumulative OCI reclassification: Amounts sitting in OCI (e.g., foreign currency translation reserves, hedging reserves) must be reclassified to profit or loss if they would ordinarily recycle — failing to do this understates the total gain or loss.
- Using carrying value instead of fair value for the retained interest: The retained interest must be remeasured to fair value at the loss-of-control date, not carried forward at its previous book value.
- Misclassifying partial disposals: Disposing of shares while retaining a majority is not a loss-of-control event. Treating it as one and recognising a gain through profit or loss is a common error (IFRS 10.23).
- Non-controlling interests presentation: Prior to loss of control, NCI must be presented separately within equity in the consolidated statement of financial position (IFRS 10.22). Getting this wrong affects the derecognition calculation at disposal.
