Key Points
- The acquirer must measure all identifiable assets and liabilities at fair value on the acquisition date, even if they were carried at cost in the acquiree's books.
- Goodwill equals the excess of consideration transferred plus any NCI over the net fair value of identifiable assets and liabilities acquired.
- Acquisition-related costs (due diligence fees, legal fees, advisory fees) are expensed as incurred and never capitalised as part of the consideration.
- The measurement period for provisional amounts lasts a maximum of 12 months from the acquisition date.
What is Business Combination (IFRS 3)?
IFRS 3.4 requires every business combination to be accounted for using the acquisition method. The method has four steps: identify the acquirer, determine the acquisition date, recognise and measure the identifiable assets acquired and liabilities assumed at fair value, and recognise goodwill (or a bargain purchase gain). The acquirer is the entity that obtains control as defined by IFRS 10.7, which does not always mean the entity that pays the cash. In reverse acquisitions, the legal acquiree can be the accounting acquirer.
IFRS 3.18 requires the consideration transferred to be measured at fair value, including cash, equity instruments issued, and contingent consideration. IFRS 3.53 treats contingent consideration as part of the transaction price at the acquisition date, measured at fair value and subsequently remeasured through profit or loss (if classified as a financial liability) or not remeasured (if classified as equity). This remeasurement rule catches teams off guard because the P&L volatility from contingent consideration earn-outs can be material in the periods following the acquisition.
The purchase price allocation (PPA) is where most of the audit effort sits. IFRS 3.13 requires the acquirer to recognise identifiable intangible assets separately from goodwill if they meet the contractual-legal or separability criterion. Customer relationships, brand names, technology patents, and order backlogs that were never on the acquiree's balance sheet appear for the first time. ISA 540.13(a) requires the auditor to evaluate whether management's method for measuring these fair values is appropriate, which in practice means testing the valuation models, discount rates, and cash flow projections underlying each identified intangible.
Worked example
Client: Danish maritime logistics company, FY2025, revenue EUR 140M, IFRS reporter. Henriksen acquires 100% of Nordvik Freight ApS (a Norwegian freight-forwarding business) on 1 July 2025 for cash consideration of EUR 22M. Nordvik's book value of net assets at the acquisition date is EUR 14M. An independent valuer identifies two previously unrecognised intangible assets: customer relationships valued at EUR 4.2M (income approach, 8-year useful life) and a trade name valued at EUR 1.1M (relief-from-royalty method).
Step 1 — Identify the acquirer and acquisition date
Henriksen pays cash and obtains 100% of voting rights, giving it control per IFRS 10.7 from 1 July 2025. Henriksen is the acquirer. The acquisition date is the date on which control transfers, which per IFRS 3.8–9 is the closing date of the share purchase agreement: 1 July 2025.
Documentation note: record the control analysis referencing the share purchase agreement, the board resolution approving the transaction, and the date on which all conditions precedent were satisfied. Confirm that the acquisition date is the date control was obtained, not the signing date.
Step 2 — Measure identifiable assets and liabilities at fair value
Book value of tangible net assets is EUR 14M. Add customer relationships at EUR 4.2M and trade name at EUR 1.1M. Deferred tax liability on the fair value uplift of the intangibles: (EUR 4.2M + EUR 1.1M) x 22% Norwegian corporate tax rate = EUR 1.17M. Total fair value of identifiable net assets = EUR 14M + EUR 4.2M + EUR 1.1M - EUR 1.17M = EUR 18.13M.
Documentation note: file the independent valuation report for each intangible asset, record the valuation method and key assumptions (discount rate, attrition rate for customer relationships, royalty rate for the trade name), and calculate the deferred tax liability on fair value adjustments per IAS 12.66. Cross-reference each identified asset to the contractual-legal or separability criterion in IFRS 3.B31–B40.
Step 3 — Calculate goodwill
Consideration transferred is EUR 22M. NCI is nil (100% acquisition). Fair value of identifiable net assets is EUR 18.13M. Goodwill = EUR 22M - EUR 18.13M = EUR 3.87M per IFRS 3.32.
Documentation note: record the goodwill calculation reconciling consideration to net assets. Allocate goodwill to the CGU expected to benefit from synergies per IAS 36.80, to be completed before the end of the first annual period after acquisition. File the basis for the CGU allocation.
Step 4 — Account for acquisition-related costs
Henriksen incurred EUR 0.6M in due diligence and legal advisory fees. IFRS 3.53 requires these to be expensed in the period incurred. They do not form part of the consideration transferred and do not increase goodwill.
Documentation note: confirm that the EUR 0.6M is recorded in operating expenses, not capitalised. Verify that no advisory fees were netted against the consideration or added to the cost of the investment in the parent's separate financial statements (where IAS 27.10 permits capitalisation under certain conditions).
Conclusion: the acquisition produces goodwill of EUR 3.87M, defensible because the PPA identifies intangible assets using an independent valuer, applies the contractual-legal and separability criteria, recognises the associated deferred tax on fair value uplifts, and expenses acquisition costs in line with IFRS 3.53.
Why it matters in practice
- Teams regularly fail to identify intangible assets separately from goodwill during the PPA. IFRS 3.13 and IFRS 3.B31–B40 require the acquirer to recognise intangible assets that meet the contractual-legal or separability criterion, even if the acquiree never recognised them. Customer relationships and order backlogs are the most commonly missed. Overstating goodwill and understating identifiable intangibles distorts subsequent amortisation and impairment testing.
- The measurement period is frequently treated as an open-ended correction window. IFRS 3.45 caps it at 12 months from the acquisition date. Adjustments after that date are changes in estimate, not measurement-period corrections, and must be recognised prospectively. ISA 540.13(b) requires the auditor to evaluate whether provisional amounts are adjusted within the permitted window. Accepting a "final PPA" 18 months post-acquisition without questioning the timeline is a documentation gap that inspection teams flag.
Business combination vs. asset acquisition
| Dimension | Business combination (IFRS 3) | Asset acquisition |
|---|---|---|
| Recognition of goodwill | Required. Goodwill equals the excess of consideration over fair value of net identifiable assets. | Not permitted. Any excess is allocated to identifiable assets on a relative fair value basis. |
| Intangible asset identification | Separate recognition required for intangibles meeting the contractual-legal or separability criterion (IFRS 3.B31). | Intangibles recognised only if they meet the general IAS 38 recognition criteria. |
| Transaction costs | Expensed as incurred (IFRS 3.53). | Capitalised as part of the cost of the assets acquired (IAS 16.16(b) or IAS 38.27). |
| Deferred tax on fair value uplifts | Recognised under IAS 12.19 (no initial recognition exemption because the transaction affects both accounting and taxable profit). | Initial recognition exemption under IAS 12.15 may apply, so deferred tax is often not recognised. |
| Contingent consideration | Measured at fair value at acquisition date; financial liability portion remeasured through P&L (IFRS 3.58). | Recognised only when the obligation meets the definition of a liability. |
The classification question arises on every acquisition engagement. A property holding company purchasing a single building with an attached lease portfolio often looks like a business combination but fails the IFRS 3.B7 concentration test. Misclassifying an asset acquisition as a business combination creates fictitious goodwill, triggers unnecessary annual impairment testing, and expenses transaction costs that should have been capitalised. The reverse error (treating a genuine business combination as an asset purchase) suppresses goodwill and avoids the PPA disclosure requirements of IFRS 3.B64.

Frequently asked questions
How do I determine whether a transaction is a business combination or an asset acquisition?
IFRS 3.B7–B12D provides an optional concentration test. If substantially all of the fair value of gross assets acquired is concentrated in a single identifiable asset (or group of similar assets), the transaction is an asset acquisition, not a business combination. If it fails the concentration test, apply the full definition: does the acquired set include inputs and substantive processes that together produce outputs? The distinction matters because asset acquisitions do not produce goodwill, do not require a PPA, and allocate the purchase price to assets on a relative fair value basis.
What happens if the fair value of net assets exceeds the consideration transferred?
IFRS 3.34–36 requires the acquirer to recognise a bargain purchase gain in profit or loss. Before doing so, the acquirer must reassess whether all assets and liabilities have been correctly identified and measured. Genuine bargain purchases are rare in practice; the standard's reassessment requirement exists because the most common cause of an apparent bargain is an incomplete or incorrect PPA rather than a genuinely below-market transaction.
Does IFRS 3 apply to common-control transactions?
No. IFRS 3.2(c) explicitly scopes out combinations of entities under common control. There is no IFRS standard governing these transactions, which means entities choose an accounting policy (often predecessor values or acquisition method by analogy). The IASB issued a project update in 2024 on common-control transactions, but no standard has been finalised. Auditors should verify which policy the entity applies and whether it is consistently followed.
