IFRS 10 Consolidation for Preparers: Document Control, Even Below 50%
Under IFRS 10 an investor consolidates an investee only when it has power, exposure to variable returns and the ability to use that power to affect those returns, as the issued standard sets out. Control, not a fixed ownership percentage, is the basis for consolidation. An investment-entity exception exists, but it changes how subsidiaries are measured rather than the underlying control analysis.
TL;DR:
A stake below 50% can still confer control when substantive rights direct relevant activities; protective vetoes alone do not, and agent status can defeat control.
Qualifying investment entities measure controlled subsidiaries at fair value through profit or loss but consolidate subsidiaries providing services to them; noninvestment parents consolidate indirect holdings.
Consolidation begins when control is obtained and ends when it is lost; align policies, eliminate intragroup effects, and present noncontrolling interests separately within equity.
If ownership changes but control remains, record an equity transaction with no profit or loss; losing control requires fair value remeasurement of any retained interest.
Maintain a dated control file mapping rights, decision makers, returns, and agency status, then reassess when contracts, governing documents, or decision makers change.

What IFRS 10 covers and what consolidated statements involve
IFRS 10 requires a parent that controls one or more entities to present consolidated financial statements. It replaced the older split between IAS 27 and SIC-12 with a single control model applied to every investee, as the text of the standard explains.
In practice, presenting on a consolidated basis means showing the group as one economic entity:
Like line items of parent and subsidiaries are aggregated, as this summary of the approach describes.
Intragroup balances, transactions, income and expenses are eliminated in full.
Non-controlling interests are identified and presented separately within equity.
Related standards do the surrounding work: IFRS 3 for business combinations, IFRS 12 for disclosures and IAS 27 for separate financial statements.
How do you determine control: power, returns and the link between them?
Each element of the test needs its own evidence, and the three must be satisfied together.
Power. Power is the current ability to direct the activities that significantly affect returns. It can arise from voting rights, contracts or other mechanisms, and ICAEW guidance notes that less than 50% of the votes can still deliver control. Only substantive rights count. Protective rights, such as veto rights over fundamental changes, do not confer power.
Exposure to variable returns. Returns may be positive, negative or both: dividends, fees, residual interests, funding support or guarantees all qualify.
The link. Power must be usable to affect those returns. A decision-maker acting as agent for others does not control, however large its fee income, so the principal-versus-agent assessment matters wherever decisions are delegated.
Potential voting rights. Options and convertibles count only when substantive, so look at exercise price, timing and whether the holder has the practical ability to exercise them.
The control model is substance-based, and Deloitte’s analysis stresses that funding or board appointments alone prove nothing.
Pro Tip: Write down who can currently direct the relevant activities before you look at who owns the most shares.
What accounting follows a consolidation conclusion?
Once control exists, the mechanics follow, and the standard itself fixes the timeline:
Consolidation starts on the date control is obtained and stops on the date control is lost. Results before that date stay out of the group numbers.
The group applies uniform accounting policies, so subsidiary ledgers often need adjusting before aggregation. The legislative text supports building acquisition-date, reporting-date, elimination and non-controlling-interest schedules separately rather than adding trial balances.
Intragroup balances, transactions and unrealised profits are eliminated in full. Intragroup monetary items in different currencies can still leave exchange differences in group profit or loss under IAS 21, a point revisited in the March 2026 IFRIC Update.
Non-controlling interests are presented within equity, separately from the parent’s owners’ equity.
For acquisition-date entries, our guide to purchase price allocation covers the adjustments that typically feed the opening consolidation.
When does the investment-entity exception apply?
The exception is narrow. An entity that qualifies as an investment entity measures its controlled subsidiaries at fair value through profit or loss instead of consolidating them, as IAS Plus summarises.
The entity must meet the standard’s investment-entity criteria in full, not merely hold a portfolio of investments.
Subsidiaries that provide investment-related services to the entity are still consolidated.
A parent that is not itself an investment entity generally consolidates everything it controls, including subsidiaries held through an investment-entity subsidiary.
Reporting then centres on fair value measurement and the related disclosures, not line-by-line aggregation.
How do you document control judgements and know when to reassess them?
Auditors ask for the reasoning, not only the conclusion. A defensible file typically contains:
A rights map listing every instrument, agreement and governance right held by each party.
A decision-maker analysis covering principal versus agent status.
An exposure analysis of the returns the investor receives or bears.
Board minutes showing who actually directs the relevant activities.
ICAEW recommends making significant control judgements explicit and describing investee relationships consistently across the annual report.
Reassess when facts change: amended governing documents, new contracts or a change in decision-makers. The IFRS Interpretations Committee discussion in the March 2026 IFRIC Update indicates that entities typically reassess when a governing document is amended. The hardest patterns are structured entities, single-investor funds and significant minority holdings, where the IFRS reassessment project points back to substantive rights and delegated decision-making.
Pro Tip: Keep one control memo per investee and date every revision, so a reassessment reads as a continuation rather than a rewrite.
How are non-controlling interests and ownership changes treated?
Changes in ownership that leave control intact are equity transactions. The carrying amounts of the controlling and non-controlling interests are adjusted, and no gain or loss reaches profit or loss, as the IFRS 10 page explains.
Non-controlling interests sit within consolidated equity and receive their share of profit or loss and other comprehensive income, even if that creates a deficit balance.
When control is lost, the parent derecognises the subsidiary’s assets, liabilities and related non-controlling interest.
Any retained interest is remeasured at fair value at that date.
The resulting gain or loss is recognised in profit or loss.
What must you disclose about control?
Disclosure requirements for subsidiaries, structured entities and significant judgements sit in IFRS 12. The expectation, reflected in the IFRS 10 standard and in ICAEW commentary, is that significant control judgements are stated explicitly.
Describe investee relationships in the same way in the strategic report, the notes and any regulatory announcements.
State the judgement where control exists with less than a majority of votes, or does not exist with more.
Align reporting dates and cut-off across group entities.
Reconcile group schedules to the ledgers before the draft goes to review.
What should preparers have ready? A practical checklist
We recommend one working file that ties each fact to the IFRS 10 paragraph it supports:
Map rights and identify the decision-makers.
Document exposure to variable returns.
Apply the link test between power and returns.
Conclude on principal versus agent status.
Then prepare separate schedules for acquisition-date adjustments, intercompany eliminations, non-controlling-interest calculations and currency translation. Give each schedule a named owner in the finance team and keep a short approval trail for auditors. Our statutory accounts guide shows how this sits alongside the wider year-end process.
Pro Tip: Build the non-controlling-interest schedule first; errors there ripple into equity, profit allocation and the cash flow statement.
Our view on IFRS 10 for growing groups
In our experience the weak point is rarely the arithmetic. It is the control memo written after the fact. We build tailored consolidation workpapers alongside the judgement file, and we encourage you to involve us early when structures are complex or fund and agent relationships are in play.

FAQ
How does IFRS 10 define control?
An investor controls an investee when it has power over it, exposure or rights to variable returns from its involvement, and the ability to use that power to affect those returns. All three must be present, according to the IFRS Foundation.
What does a consolidated basis mean?
Presenting on a consolidated basis means showing the parent and its subsidiaries as a single economic entity. Like items are aggregated, intragroup effects are eliminated and non-controlling interests are shown separately.
What does financial consolidation mean?
Financial consolidation is the process of combining the financial statements of a parent and the entities it controls into one set of group statements. It involves uniform policies, eliminations and the allocation of profit between owners and non-controlling interests.
What are equity method investments?
Equity method investments are interests in associates and joint ventures where the investor has significant influence or joint control but not control. They are carried as a single line rather than consolidated, so IFRS 10 does not apply to them.
