IFRS 3 Acquisition Method vs Pooling of Interests

Side-by-side comparison

Apply the acquisition method for every business combination under IFRS. Pooling of interests is not available. If the transaction involves entities under common control, IFRS 3.2 (c) scopes it out entirely, and the entity selects its own policy (often predecessor values). That policy is not pooling of interests as previously defined.

Where this distinction still surfaces

At firms like ours, the distinction comes up in two situations. First, entities that completed combinations before 2004 may carry legacy pooling-of-interests balances. IFRS 3 (2004 and 2008 revisions) applied prospectively, so combinations accounted for under pooling before the effective date were not restated. The combined balance sheet from those older transactions contains no goodwill and no fair value (FV) uplift on identifiable assets. If the engagement team encounters a pre-2004 subsidiary with no goodwill on the consolidated balance sheet, it must verify whether the original combination used pooling and confirm that IFRS 3 's prospective application justifies the absence of goodwill ( IFRS 3.67 -68).

Second, the distinction appears in cross-border groups where a subsidiary reports under a local GAAP that still permits or requires a pooling-like method for common-control transactions. German HGB, for example, allows a carrying-amount method (Buchwertmethode) for certain reorganisations. The group engagement team must ensure that the IFRS consolidation applies the acquisition method even when the local statutory accounts used a different approach. ISA 600 .A38 requires understanding the group structure and the accounting frameworks applied at each component.

Worked example: Schafer Elektrotechnik AG

Client: German electronics manufacturer, FY2025, revenue EUR 310M, IFRS reporter. Schafer acquires 100% of Prestel Sensorik GmbH (a sensor manufacturer with book value of net assets at EUR 18M) on 1 July 2025 for EUR 29M cash. An independent valuer identifies customer relationships at EUR 3.8M and proprietary sensor technology at EUR 2.4M. The deferred tax liability on FV uplifts at 30% German corporate tax rate is EUR 1.86M.

Step 1: measure identifiable net assets at FV

Book value EUR 18M plus customer relationships EUR 3.8M plus sensor technology EUR 2.4M less deferred tax liability EUR 1.86M equals FV of identifiable net assets of EUR 22.34M.

File the independent valuation report for each intangible and record the valuation methods (income approach for customer relationships, relief-from-royalty for sensor technology). Calculate the deferred tax liability per IAS 12.66 .

Step 2: calculate goodwill

Consideration of EUR 29M less FV of identifiable net assets of EUR 22.34M equals goodwill of EUR 6.66M per IFRS 3.32 . Allocate this goodwill to the sensor division CGU per IAS 36.80 .

Record the goodwill calculation and the CGU allocation rationale. Confirm that annual impairment testing is scheduled per IAS 36.96 .

Step 3: consolidate from acquisition date

Schafer includes Prestel's results from 1 July 2025 onward only. Pre-acquisition profits stay with the selling shareholders.

Confirm the acquisition date per IFRS 3.8 -9. Verify that revenue and expenses before 1 July 2025 are excluded from the consolidated income statement.

Under pooling of interests (hypothetical, not permitted)

Schafer would carry forward Prestel's net assets at book value of EUR 18M. No customer relationships or sensor technology would be separately recognised. No goodwill would arise. Prestel's full-year results (January to December 2025) would be combined with Schafer's results, making consolidated revenue and profit appear higher for the year. The EUR 29M payment would reduce equity rather than create an asset.

If the engagement team failed to apply the acquisition method (perhaps because the German statutory accounts used the Buchwertmethode for a parallel HGB filing), the IFRS consolidated balance sheet would omit EUR 6.66M of goodwill and EUR 6.2M of intangible assets. It would also miss EUR 1.86M of deferred tax liabilities. Post-combination earnings would be overstated by the missing amortisation on the intangibles.

Why it matters in practice

We have seen teams working on groups with pre-2004 combinations assume that all legacy pooling balances should be restated to the acquisition method. IFRS 3.67 -68 applied the standard prospectively. Restating a 2002 combination would require FVs that may be impossible to determine reliably two decades later. The correct approach is to leave the legacy balances in place and document the basis for doing so. Trying to reconstruct FVs from 20-year-old records is genuinely one of the more frustrating dead ends you can walk into on a group audit file.

On cross-border engagements, practitioners occasionally carry forward the local GAAP carrying-amount treatment into the IFRS consolidation for common-control reorganisations, treating it as pooling by another name. IFRS 3.2 (c) scopes out common-control transactions, but this does not mean pooling applies. The entity must select and disclose an accounting policy. ISA 600 .A38 requires the group engagement team to verify that the IFRS consolidation applies a policy consistent with the IFRS framework, not the local statutory approach. In our experience, the file should tell a story about why the chosen policy fits the group's facts (not just restate the standard's scoping paragraph).
