IFRS 3 Business Combinations — Complete Guide

What is IFRS 3?

IFRS 3 Business Combinations governs how an acquirer accounts for acquiring control of another business. It establishes the acquisition method as the single required approach for all business combinations — replacing the old pooling of interests method that some countries previously allowed.

IFRS 3 is a core topic in ACCA Strategic Business Reporting (SBR) and appears in group accounting questions at both FR and SBR level.

The Acquisition Method

IFRS 3 requires all business combinations to use the acquisition method, which involves four steps:

Step 1: Identify the Acquirer

The acquirer is the entity that obtains control of the acquiree. Control generally means ownership of more than 50% of voting rights, but can arise through other means (contractual arrangements, potential voting rights, etc.).

Step 2: Determine the Acquisition Date

The date on which the acquirer obtains control — generally the date when consideration is transferred, assets acquired, and liabilities assumed.

Step 3: Recognise and Measure Identifiable Assets, Liabilities, and Non-controlling Interests

At acquisition date, the acquirer recognises:

• All of acquiree's identifiable assets and liabilities at fair value — even those not previously recognised in the acquiree's accounts (e.g. internally generated intangibles that meet IAS 38 criteria)
• Non-controlling interests (NCI): Measured at either (i) fair value (full goodwill method) OR (ii) proportionate share of net identifiable assets (partial goodwill method) — accounting policy choice per transaction

Step 4: Recognise and Measure Goodwill or Gain on Bargain Purchase

Goodwill = Consideration transferred + NCI at acquisition date − Net fair value of identifiable assets and liabilities

If the result is negative (rare), it is a bargain purchase — recognised immediately in P&L after reassessing the measurement.

Goodwill Under Full vs Partial Goodwill Methods

Contingent Consideration

If part of the acquisition price depends on future events (e.g. earn-outs based on future earnings), contingent consideration is recognised at fair value at acquisition date. Subsequently:

• Classified as a liability: remeasured at fair value through P&L at each reporting date
• Classified as equity: not remeasured after initial recognition

Changes in contingent consideration are NOT adjustments to goodwill (post-acquisition).

Post-Acquisition Adjustments

The measurement period (up to 12 months) allows retrospective adjustment of provisional fair values when new information becomes available about conditions at acquisition date. After the measurement period, adjustments go to P&L.

Exam Tips for IFRS 3

• Always use fair values for net assets at acquisition date — not carrying amounts
• Identify any contingent assets/liabilities and previously unrecognised intangibles
• Know both NCI methods and when each is tested
• Contingent consideration: always recognise at fair value at acquisition; subsequent changes to P&L (liability) or no remeasurement (equity)
• Acquisition costs (professional fees, due diligence) are expensed — NOT added to cost of investment
