Complex Group Structures and Ownership Changes
Introduction
A group’s legal and economic structure may change repeatedly while the reporting entity continues to operate. An investor may acquire control in stages, purchase additional shares after obtaining control, sell an interest while retaining control, or dispose of enough shares to lose control. Groups may also contain indirect and reciprocal holdings, subsidiaries intended for resale, and goodwill requiring impairment testing.
These events cannot all be treated as ordinary purchases and sales of investments. Their accounting depends principally on whether control is obtained, retained or lost. Under IFRS Accounting Standards, IFRS 3 governs obtaining control of a business, IFRS 10 governs consolidation and ownership changes, IFRS 5 addresses disposal groups held for sale, and IAS 36 governs impairment.
Unless otherwise stated, monetary amounts in this chapter are currency units (CU), the acquiree is a business, ownership interests carry proportionate voting rights, and tax effects are ignored for clarity.
Learning Objectives
After studying this chapter, students should be able to:
account for a business combination achieved in stages;
distinguish ownership changes that retain control from those that cause loss of control;
calculate the equity effects of purchases and disposals involving NCI;
account for retained interests following loss of control;
analyse indirect and reciprocal ownership structures;
account for subsidiaries acquired with a view to resale;
apply IAS 36 to goodwill under full- and partial-goodwill measurement; and
evaluate disclosure, governance and implementation issues arising from complex structures.
1. Control as the Organising Principle
Under IFRS 10, an investor controls an investee when it has:
power over the investee;
exposure, or rights, to variable returns from its involvement; and
the ability to use its power to affect those returns.
Ownership percentage is important evidence but is not conclusive. Control can exist below 50% where other shareholders are widely dispersed, and it may be absent above 50% where substantive rights restrict decision-making.
The accounting treatment follows three control boundaries:
Event
Economic interpretation
Principal treatment
Control is obtained
Business combination
Acquisition method; remeasure previously held interest
Ownership changes but control continues
Transaction with owners
Equity transaction; no new goodwill or profit
Control is lost
Disposal of subsidiary
Derecognise subsidiary; recognise gain or loss

2. Business Combinations Achieved in Stages
A step acquisition occurs when an investor obtains control after already holding an interest in the acquiree. The acquisition date is the date control is obtained, not the date of the first share purchase.
At that date, IFRS 3 requires the acquirer to:
measure consideration transferred at fair value;
remeasure the previously held interest to acquisition-date fair value;
recognise the resulting gain or loss in profit or loss, subject to the treatment required for related OCI amounts;
recognise identifiable assets acquired and liabilities assumed, generally at acquisition-date fair value;
measure qualifying non-controlling interests; and
recognise goodwill or a bargain-purchase gain.
2.1 Goodwill in a step acquisition
G = C + FP + N - FA
where:
G = goodwill in CU;
C = fair value of consideration transferred for the additional interest;
FP = acquisition-date fair value of the previously held interest;
N = acquisition-date measurement of NCI; and
FA = fair value of identifiable net assets acquired.
This formula applies where the result is positive. A negative provisional result requires reassessment of all measurements before recognition as a bargain-purchase gain in profit or loss.
2.2 NCI measurement election
For each business combination, qualifying present ownership interests that entitle holders to a proportionate share of the acquiree’s net assets on liquidation may be measured at either:
fair value—the full-goodwill method; or
the proportionate share of recognised identifiable net assets—the partial-goodwill method.
The election does not necessarily apply to every instrument classified as NCI. Other NCI components, such as certain options or share-based instruments, are measured at fair value or under another applicable IFRS requirement.
Worked Example 1: Obtaining control in stages
Arden Ltd owns 30% of Bex Ltd. Its carrying amount is CU420,000 and acquisition-date fair value is CU500,000. Arden purchases another 50% for CU1,000,000 and obtains control. The fair value of the remaining 20% NCI is CU360,000, and identifiable net assets have a fair value of CU1,600,000.
The remeasurement gain is:
Remeasurement gain = CU500,000 − CU420,000 = CU80,000
The CU80,000 gain is recognised in profit or loss, while goodwill of CU260,000 is recognised in the consolidated statement of financial position.
Amounts previously recognised in OCI are accounted for as if the earlier interest had been disposed of. Consequently, some amounts are reclassified to profit or loss, while others may be transferred directly within equity, depending on the relevant IFRS Standard.
3. Ownership Changes Without Loss of Control
Once control exists, transactions between the parent and NCI that do not change control are transactions with owners in their capacity as owners. IFRS 10 therefore prohibits recognition of:
additional goodwill;
a bargain-purchase gain; or
a gain or loss in profit or loss.
Assets and liabilities of the subsidiary remain at their consolidated carrying amounts.
3.1 Additional purchase from NCI
When the parent purchases an additional interest while retaining control:
Equity adjustment attributable to owners of parent = Decrease in NCI carrying amount − Consideration paid
A positive amount increases parent equity; a negative amount decreases it. The formula uses the decrease, not an increase, in the carrying amount of NCI.
Worked Example 2: Additional purchase
A parent owns 70% of a subsidiary and purchases a further 10% for CU240,000. Immediately before the transaction, the 30% NCI has a carrying amount of CU600,000. Assuming equal rights per share, one-third of the NCI is acquired:
NCI is debited by CU200,000, cash is credited by CU240,000, and equity attributable to the parent is debited by CU40,000.
3.2 Partial disposal while retaining control
When shares are sold without loss of control:
Equity adjustment attributable to owners of parent = Consideration received − Increase in NCI carrying amount
For example, a parent reduces its holding from 80% to 65%. The existing 20% NCI is CU350,000, and the 15% sold has equivalent rights. The increase in NCI is:
CU350,000 × (15% ÷ 20%) = CU262,500
If proceeds are CU300,000, parent equity increases by CU37,500. No disposal gain is reported in profit or loss.
Proportional calculations are appropriate only where interests have identical rights. Different share classes, preference rights or contractual arrangements require rights-based measurement.
4. Loss of Control
Loss of control represents a major economic event because the parent ceases to consolidate the former subsidiary. On that date, the parent:
derecognises all assets, including goodwill, and liabilities of the subsidiary;
derecognises the carrying amount of NCI;
recognises consideration received at fair value;
recognises any retained investment at fair value;
recognises the resulting gain or loss; and
accounts for accumulated OCI as required for a direct disposal of the related assets or liabilities.
D = CR + FR + NC − AN
where:
D = gain or loss on loss of control;
CR = fair value of consideration received;
FR = fair value of any retained interest;
NC = carrying amount of NCI derecognised; and
AN = carrying amount of the subsidiary’s net assets, including recognised goodwill.
All terms are measured at the date control is lost. A positive result is a gain and a negative result is a loss.
Worked Example 3: Disposal causing loss of control
A subsidiary’s assets, including goodwill, have a carrying amount of CU2,400,000 and liabilities are CU700,000. Thus, consolidated net assets are CU1,700,000. NCI is CU340,000. The parent receives CU1,300,000 and retains an interest worth CU170,000.
D = CU1,300,000 + CU170,000 + CU340,000 − CU1,700,000 = CU110,000 gain
The retained interest is initially recognised at CU170,000. Its subsequent accounting depends on whether it is an associate, joint venture or financial asset.
Loss of control may occur without a sale—for example, through expiry of contractual rights, dilution following a share issue, or government seizure.
5. Indirect Holdings
An indirect holding exists when a parent controls one entity through another group entity. Legal ownership and the economic attribution of profits must be distinguished.
Suppose P owns 80% of S1, and S1 owns 75% of S2. If these rights provide control, P controls both entities. P’s effective economic interest in S2 is:
Effective parent interest = 80% × 75% = 60%
The effective NCI interest in S2 is 40%, comprising:
direct NCI in S2: 25%; and
indirect interest of S1’s NCI: 20% × 75% = 15%.
If S2 earns CU100,000 after tax, CU60,000 is economically attributable to owners of P and CU40,000 to NCI, assuming equal rights and no other adjustments.
Indirect group ownership structure

Figure: Indirect ownership through an intermediate subsidiary.
In practice, profit attribution also requires adjustments for acquisition-date fair values, intragroup transactions, impairment and different classes of shares.
6. Reciprocal and Circular Ownership
Reciprocal ownership occurs when group entities hold shares in one another. It creates circular economic claims and can obscure voting power, NCI and profit attribution.
If a subsidiary holds shares in its parent, those parent shares are treated as treasury shares in the consolidated financial statements. The subsidiary’s investment asset is eliminated against consolidated equity; dividends on those shares are not group income.
More complex structures may involve two subsidiaries owning shares in each other. A reliable analysis should:
map every direct legal holding;
identify external shareholders and substantive voting rights;
eliminate intragroup investments and related income;
solve circular economic interests where necessary; and
verify that profit and equity attribution does not double count claims.
For two reciprocally owned entities A and B, suppose P directly owns 80% of A and 70% of B, A owns 10% of B, and B owns 20% of A. Let eA and eB represent P’s effective economic interests. Then:
eA = 0.80 + 0.20eB
eB = 0.70 + 0.10eA
Substitution gives:
eA = 0.80 + 0.20(0.70 + 0.10eA) = 0.94 + 0.02eA
Therefore, eA = 0.94 ÷ 0.98 = 0.959184, or approximately 95.92%, and eB = 0.70 + 0.10(0.959184) = 79.59%.
These effective percentages describe circular economic claims; they do not replace the IFRS 10 control assessment or legal analysis of shareholder rights. In large networks, matrix methods and consolidation software are commonly used, but model outputs must be reconciled to legal registers and contractual terms.
7. Subsidiaries Acquired for Disposal
A subsidiary acquired exclusively with a view to resale is not exempt from consolidation. It is consolidated from the date control is obtained and may then qualify as a disposal group held for sale under IFRS 5.
Classification requires, among other matters, that the disposal group be available for immediate sale in its present condition and that sale be highly probable. For a newly acquired subsidiary, criteria not met on the acquisition date may generally be completed within a short period, normally three months, if the one-year sale requirement is expected to be satisfied.
A qualifying disposal group is measured at the lower of:
Carrying amount and fair value less costs to sell
Before classification, assets and liabilities are measured under their applicable IFRS Standards. Certain assets within a disposal group—such as deferred tax assets, employee-benefit assets and financial instruments—continue to be measured under their own Standards.
Any IFRS 5 impairment loss is allocated first to goodwill and then pro rata to other non-current assets within IFRS 5’s measurement scope, subject to applicable floors. A subsidiary acquired exclusively with a view to resale may also meet the definition of a discontinued operation.
8. Impairment of Goodwill and Group Assets
Goodwill does not generate cash flows independently. IAS 36 therefore requires it to be allocated from the acquisition date to the cash-generating units (CGUs), or groups of CGUs, expected to benefit from the combination. Each allocation level must be monitored internally and cannot be larger than an operating segment before aggregation.
A CGU containing goodwill is tested annually and whenever impairment indicators exist.
Impairment loss = max(0, Carrying amount − Recoverable amount)
Recoverable amount is the higher of:
value in use; and
fair value less costs of disposal.
An impairment loss is allocated first to goodwill and then pro rata to other CGU assets, without reducing an asset below the highest of its individual fair value less costs of disposal, value in use where determinable, and zero. Goodwill impairment is never reversed.
8.1 Partial-goodwill gross-up procedure
When NCI was measured using the partial-goodwill method, only the parent’s share of goodwill is recognised. However, the CGU’s recoverable amount normally reflects cash flows attributable to both parent and NCI. IAS 36 therefore requires a notional gross-up of goodwill for impairment testing so that the comparison uses a consistent basis.
The unrecognised NCI goodwill is included only in the impairment test; it is not recognised as an asset.
Worked Example 4: Grossing up partial goodwill
A parent owns 80% of a subsidiary. Recognised partial goodwill is CU240,000, and other CGU assets have a carrying amount of CU1,000,000. Recoverable amount is CU1,150,000.
Notional total goodwill = CU240,000 ÷ 80% = CU300,000
The notionally adjusted carrying amount is CU1,300,000. Total notional impairment is therefore:
CU1,300,000 − CU1,150,000 = CU150,000
Because the loss is smaller than total notional goodwill, it is allocated entirely to goodwill. Only the parent’s recognised share is recorded:
Recognised goodwill becomes CU120,000. The CU30,000 relating to unrecognised NCI goodwill is not recorded. If impairment exceeded notional goodwill, the excess allocated to recognised CGU assets would be recognised subject to IAS 36 allocation limits.
Under full goodwill, both parent and NCI goodwill are recognised, so the full goodwill impairment is recorded and attributed between parent and NCI according to the relevant ownership interests or other rights.
9. Illustrative Integrated Case: Orion Group
This is a fictional illustrative case.
Background
Orion Ltd held 30% of Luna Ltd as an associate. The investment’s carrying amount was CU480,000. On 1 July, Orion bought another 50% for CU1,100,000 and obtained control. The original interest had a fair value of CU550,000, NCI fair value was CU420,000, and identifiable net assets were CU1,800,000.
Six months later, Orion purchased another 10% for CU230,000. Immediately before this purchase, the 20% NCI had a carrying amount of CU390,000. Subsequently, Orion sold sufficient shares to reduce its ownership from 90% to 40%, receiving CU1,000,000 and losing control. At that date, the retained interest was worth CU720,000, Luna’s consolidated net assets including goodwill were CU2,000,000, and the remaining 10% NCI was CU220,000.
Analysis and solution
Obtaining control:
Remeasurement gain = CU550,000 − CU480,000 = CU70,000
Orion recognises a CU60,000 loss before any required reclassification of accumulated OCI. The retained 40% interest is initially recognised at CU720,000 and is normally accounted for as an associate if Orion has significant influence.
Outcome and learning points
The three transactions use different accounting models even though each involves Luna shares. Obtaining control creates a remeasurement gain and goodwill; the additional purchase affects equity only; and loss of control produces a disposal loss and fair-value recognition of the retained interest. The case demonstrates why consolidation systems must identify control status at every transaction date.
10. Professional, Governance and Technology Considerations
Complex structures create opportunities for error and manipulation. Management may structure transactions near reporting dates to influence reported gains, conceal leverage in special-purpose entities, or avoid transparent presentation of disposals. Audit committees should challenge control judgments, valuation assumptions and the commercial substance of linked transactions.
Best practice includes maintaining current ownership charts, reconciling legal share registers, documenting control assessments, obtaining independent valuations where material, and separately tracking parent and NCI equity movements.
Modern consolidation platforms can automate ownership matrices, currency translation and elimination entries. AI tools can flag inconsistent ownership percentages or unusual journal entries. They cannot independently determine whether rights are substantive, whether transactions are linked, or whether a sale is highly probable. Professional judgment and accountable human review remain essential.
Chapter Summary
Accounting for ownership changes is governed by the status of control. A step acquisition applies acquisition accounting and remeasures the previously held interest. Changes that retain control are equity transactions: an additional purchase uses the decrease in NCI carrying amount, while a partial disposal uses the increase in NCI. Loss of control requires derecognition of the entire subsidiary, fair-value recognition of any retained interest, and recognition of a gain or loss.
Indirect and reciprocal holdings require careful mapping of legal rights and economic interests. Subsidiaries acquired for resale are still consolidated and may subsequently qualify for IFRS 5 classification. Goodwill must be allocated to CGUs and tested under IAS 36. Where partial goodwill was recognised, goodwill is notionally grossed up to ensure a consistent impairment comparison, but impairment related to unrecognised NCI goodwill is not recorded.
