For groups that must navigate both IFRS and US GAAP — either because they operate across jurisdictions with different reporting requirements, or because they are preparing for a US listing while currently reporting under IFRS — the differences in consolidation rules are not only about accounting policies. They extend to which entities must be consolidated in the first place, how the acquisition of a subsidiary is measured, and how minority shareholders’ interests are presented. These structural differences produce different balance sheets and different goodwill amounts for the same underlying group structure, depending on which framework applies.
A separate post in this series covers the accounting policy differences that require restatement adjustments at consolidation (LIFO/FIFO, asset revaluation, lease classification, and others). This post focuses on the consolidation scope and structure differences — where IFRS 10 and US GAAP ASC 810 diverge on who to consolidate and how to measure what you consolidate.
Difference 1: How Control Is Determined
The most fundamental question in consolidation is: which entities must be included? Both frameworks require consolidation of entities under the parent’s control — but they define control differently.
IFRS 10: Principles-based control
Under IFRS 10, control exists when a parent has all three of the following simultaneously:
- Power over the investee: the ability to direct the activities that significantly affect the investee’s returns (relevant activities)
- Exposure to variable returns: exposure to positive or negative returns from the investee that can vary with its performance
- Ability to use power to affect returns: the ability to use its power to influence those variable returns
Power can arise from voting rights, contractual arrangements, or other mechanisms. A company with 45% voting rights but board appointment rights, veto rights over key operating decisions, and management contracts may have power over the relevant activities — and therefore control — under IFRS 10, even without majority ownership.
US GAAP ASC 810: Two parallel frameworks
US GAAP uses two separate models, applied sequentially:
The Variable Interest Entity (VIE) model is applied first. A VIE is an entity that either has insufficient equity to finance its activities without additional financial support, or whose equity holders lack certain decision-making rights or economic exposure characteristics. When a VIE is identified, the primary beneficiary — the party that (i) has the power to direct the most significant activities of the VIE and (ii) has the obligation to absorb losses or the right to receive benefits that could potentially be significant — must consolidate the VIE, regardless of voting ownership.
The Voting Interest model applies to entities that are not VIEs. Here, majority voting interest (more than 50%) creates a presumption of control and consolidation is required.
Where the frameworks diverge A bank provides $80M of senior debt to a special purpose vehicle (SPV) that holds real estate assets. The SPV is funded by $80M of debt and $5M of equity from an external investor. The bank’s covenants give it significant influence over the SPV’s asset management and disposal decisions.
US GAAP analysis: The SPV may be a VIE — its equity is likely insufficient to finance its activities. The bank, as the party with power over the most significant activities (asset management) and exposure to the majority of losses (as the primary lender), may be the primary beneficiary and required to consolidate the SPV despite holding no equity.
IFRS 10 analysis: Under IFRS 10, the bank would need to assess whether it has power over the relevant activities and exposure to variable returns. If the bank’s involvement is purely as a lender with standard creditor rights, it may not have power over relevant activities — and therefore may not consolidate the SPV under IFRS.
💡 The practical consequence: the same structured finance arrangement may require consolidation under US GAAP (VIE primary beneficiary) but not under IFRS, or vice versa. For groups with structured entities, SPEs, or non-standard ownership arrangements, a full assessment under both frameworks is necessary when determining consolidation scope.
Difference 2: NCI Measurement — Full vs Partial Goodwill
When a parent acquires less than 100% of a subsidiary, the non-controlling interest (NCI) must be measured at the acquisition date. The two frameworks diverge here in a way that produces different goodwill amounts on the consolidated balance sheet.
US GAAP (ASC 805): Requires the full goodwill method exclusively. NCI is measured at its fair value at acquisition date — which includes the NCI’s proportionate share of the acquired entity’s goodwill.
IFRS (IFRS 3): Allows a choice for each acquisition: either the full goodwill method (NCI at fair value, same as US GAAP) or the partial goodwill method (NCI measured at the NCI’s proportionate share of the subsidiary’s identifiable net assets only — excluding any NCI goodwill).
Worked example — full vs partial goodwill Parent acquires 80% of Subsidiary for $800,000.
Fair value of Subsidiary’s identifiable net assets at acquisition: $900,000.
Fair value of 100% of Subsidiary (implied by the 80% acquisition price): $800,000 / 80% = $1,000,000.
Full goodwill method (US GAAP / IFRS option 1):
Total goodwill = $1,000,000 − $900,000 = $100,000
NCI at fair value = $1,000,000 × 20% = $200,000
Goodwill on balance sheet: $100,000 | NCI equity: $200,000
Partial goodwill method (IFRS option 2):
Goodwill = $800,000 − ($900,000 × 80%) = $800,000 − $720,000 = $80,000
NCI = $900,000 × 20% = $180,000 (share of identifiable net assets only)
Goodwill on balance sheet: $80,000 | NCI equity: $180,000
Difference: $20,000 less goodwill and $20,000 less NCI equity under partial goodwill. The difference ($20,000) is the NCI’s share of goodwill — recognised under the full method, excluded under the partial method.
The choice of method has consequences beyond the initial balance sheet. When the CGU containing goodwill is tested for impairment under the partial goodwill method, the goodwill must be “grossed up” to include the unrecognised NCI goodwill before comparing to the recoverable amount — then any impairment is allocated back on the same basis. This makes impairment testing more complex under partial goodwill, not simpler.
| Metric | Full goodwill | Partial goodwill |
|---|---|---|
| Goodwill on balance sheet | Higher ($100,000) | Lower ($80,000) |
| NCI equity | Higher ($200,000) | Lower ($180,000) |
| Total assets | Higher | Lower |
| Return on assets (RoA) | Lower (larger asset base) | Higher (smaller asset base) |
| Impairment testing | Straightforward | Requires grossing-up goodwill |
Difference 3: Uniform Accounting Policies
IFRS explicitly requires that all entities included in a group consolidation use uniform accounting policies for like transactions and events in similar circumstances (IFRS 10.B87). Where a subsidiary uses different policies, its figures must be adjusted to the group standard before consolidation.
US GAAP does not have an equivalent explicit requirement, though consistency in presentation is implied and auditors in practice expect consistency for material items. The practical difference: IFRS groups are explicitly required to make policy alignment adjustments for every material difference between entity and group accounting policy; US GAAP groups have more flexibility to present subsidiaries on their own basis where the difference is judgement-based rather than a specific rule conflict.
Practical Implications for Global Groups
For CFOs managing groups with entities under both frameworks, the consolidation differences create three specific operational challenges:
Scope assessment for each entity: The VIE assessment under US GAAP and the control assessment under IFRS 10 can produce different consolidation scopes. Groups need to maintain separate consolidation scope documentation for each framework — the list of entities consolidated is not automatically the same.
Goodwill reconciliation: Where a group has acquisitions under which the partial goodwill method was applied for IFRS, a separate calculation for US GAAP is required to restate to the full goodwill method. This is a recurring reconciliation item, not a one-time adjustment, because goodwill affects impairment testing every year.
NCI presentation: Under both frameworks, NCI is presented as a separate component of equity. But the NCI amount at acquisition differs under the two methods, and subsequent movements (NCI’s share of profit, NCI’s share of comprehensive income, dividends to NCI) flow through differently depending on the opening NCI balance.
