Every business combination under IFRS is accounted for using the acquisition method. There is no pooling of interests, no merger accounting, no fresh-start accounting. One entity acquires another. The acquirer measures what it paid, recognises what it got, and the difference is either goodwill or a bargain purchase gain.
That single-method mandate sounds simple. The complexity sits in the details: determining whether a transaction is a business combination at all, identifying who the acquirer actually is (which is not always the legal acquirer), and measuring the consideration and identifiable net assets precisely. Post 47 covers goodwill, contingent consideration, and step acquisitions. This post covers the foundational steps: the business definition, acquirer identification, the acquisition date, and the core measurement principles.
Is It a Business Combination? The Threshold Question
IFRS 3 applies only when an entity obtains control of a business. Two questions must be answered before the acquisition method is applied:
Has control been obtained? (IFRS 10 determines this.)
Is what was acquired a business? (IFRS 3 defines this.)
If the answer to either question is no, IFRS 3 does not apply. The transaction is either a control event without a business (accounted for as an asset acquisition) or a business transaction without a control event (accounted for under IFRS 9 or other applicable standards).
What Is a Business?
A business is defined as an integrated set of activities and assets that is capable of being conducted and managed for the purpose of generating returns.
Three elements must be present: inputs, processes, and outputs. The 2018 amendment to IFRS 3 changed the emphasis: inputs include non-current assets, intellectual property, or specialised workforce. A process is any system or structure that converts the input into an output, such as revenue, reduced costs, or other economic benefits.
Outputs are no longer essential for the set to qualify as a business. A start-up that has inputs and processes but has not yet generated revenue can be a business. What matters is whether the inputs and processes together are capable of producing outputs.
The Concentration Test: An Optional Shortcut
The 2018 amendment introduced an optional concentration test. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, it is considered not a business.
The concentration test is optional. Entities may choose to apply, or not to apply, this simplified assessment process for each acquisition. If the concentration test is met, the acquired set of activities and assets is determined not to be a business. If the test is not met, or if the acquirer elects not to apply the test, then a full assessment needs to be determined to assess whether a business has been acquired or not.
The concentration test is practically useful for real estate and single-asset acquisitions. An entity acquiring a portfolio of investment properties where substantially all the value is in the land and buildings (with minimal process infrastructure) can use the concentration test to conclude it is acquiring assets, not a business, avoiding the IFRS 3 acquisition method entirely.
The asset acquisition versus business combination distinction has significant financial statement consequences. Asset acquisitions: no goodwill recognised, no deferred tax on fair value step-ups of acquired assets, transaction costs capitalised. Business combinations: goodwill recognised, deferred tax on fair value step-ups, transaction costs expensed.
Indian context: when Tata Consultancy Services acquires a small software product company with a team, intellectual property, and customer relationships, it is almost certainly acquiring a business. When a real estate developer acquires a land parcel from another developer, it is acquiring an asset. The distinction drives dramatically different accounting.
Business Combinations Under Common Control
IFRS 3 explicitly excludes business combinations under common control. When Reliance Industries transfers one subsidiary to another subsidiary within the Reliance group, both before and after the transfer are under the same ultimate control of the Reliance group. IFRS 3 does not apply.
No IFRS standard currently addresses common control transactions comprehensively. Entities typically apply either the acquisition method by analogy or the book value (predecessor value) method. The IASB has a long-running project on common control transactions; as of mid-2026 it has not issued a final standard. This remains one of the most significant gaps in IFRS.
In India, scheme-of-arrangement restructurings within conglomerates are common. The Tata group regularly restructures subsidiaries through NCLT-approved schemes. Where both entities are under Tata Sons' common control, IFRS 3 does not govern the accounting. Indian companies often apply the predecessor value method for such transactions, reflecting the carrying amounts of the transferred entities rather than fair values.
The Four Steps of the Acquisition Method
Once a transaction is confirmed as a business combination, the acquisition method requires four steps:
Step 1: Identify the acquirer.
Step 2: Determine the acquisition date.
Step 3: Recognise and measure the identifiable assets acquired, liabilities assumed, and any non-controlling interest.
Step 4: Recognise and measure goodwill or a gain from a bargain purchase.
Step 1: Identifying the Acquirer
The acquirer is the entity that obtains control of the acquiree. The legal owner and the accounting acquirer are usually the same entity. In most transactions, the company that pays cash or issues shares to acquire another is clearly the acquirer.
However, IFRS 3 requires an in-substance approach to identify the party that obtained control. This approach looks beyond the legal form of the transaction and considers the rights of the combining entities and their former owners.
IFRS 3 directs entities to IFRS 10 to identify the acquirer: the entity that has power over the acquiree, exposure to variable returns, and the ability to use power to affect those returns.
Indicators of the Acquirer in Complex Situations
Where the acquirer is not obvious from the legal form, IFRS 3 provides indicators:
Relative size: The significantly larger entity is usually the acquirer. If Wipro (market cap Rs. 3 lakh crore) acquires a US analytics firm (valued at Rs. 800 crore), Wipro is the acquirer.
Who initiates the combination: The entity that initiates the combination and drives the transaction is typically the acquirer.
Composition of the governing body: If the former owners of one entity obtain the majority of the combined entity's board, that entity is likely the acquirer.
Composition of senior management: If the combined entity's senior leadership is dominated by former management of one entity, that entity is often the acquirer.
Payment of premium: The entity that pays a premium above the other's pre-combination fair value has demonstrated willingness to pay for control, identifying itself as the acquirer.
Reverse Acquisitions
A reverse acquisition occurs when an entity that issues securities (the legal parent or the legal acquirer) is identified as the accounting acquiree, and accordingly, the legal subsidiary (or the legal acquiree) is identified as the accounting acquirer.
Private operating companies seeking a fast-track stock exchange listing sometimes arrange to be acquired by a smaller listed company (often described as a shell company). This usually involves the listed shell company issuing its shares to the private company shareholders in exchange for their shares in the private operating company.
In such transactions, the legal acquirer (the shell) issues shares, but the former owners of the private operating company end up controlling the combined entity. The private operating company is the accounting acquirer. A reverse acquisition that is a business combination can occur only if the accounting acquiree meets the definition of a business under IFRS 3.
The financial statements after a reverse acquisition are presented in the name of the legal parent (the listed shell) but reflect the financial history of the accounting acquirer (the private operating company). The legal capital is restated to show the capital of the legal parent, adjusted to reflect the equity of the accounting acquirer.
Indian context: several Indian private companies have pursued listings through reverse merger structures with listed shell entities. Where these structures involve the shell acquiring the operating company but the operating company's shareholders ending up in control, the accounting acquirer analysis under IFRS 3 becomes critical. Getting this wrong affects whether goodwill is recognised, whose historical financials are carried forward, and how the combined entity's equity is presented.
Step 2: The Acquisition Date
The acquisition date is the date the acquirer obtains control. In most cash acquisitions, this is the closing date: the date consideration is transferred, assets are received, and the entity is legally consolidated.
Control passes when all of the following exist simultaneously: power over the acquiree, exposure to variable returns, and the ability to use power to affect those returns.
Regulatory approvals can delay the legal closing but do not always delay control. If CCI approval is pending but the acquirer has already obtained de facto control (through a binding agreement that gives it rights over the acquiree's activities), the acquisition date may be the economic control date, not the regulatory approval date.
Getting the acquisition date right matters. Fair values of identifiable assets and liabilities are measured at the acquisition date. The acquiree's results are consolidated from the acquisition date, not the date of the agreement. A deal signed in December 2024 with regulatory approval in March 2025 has an acquisition date of March 2025 if regulatory approval was genuinely required for control.
Step 3: Recognising and Measuring Identifiable Assets and Liabilities
At the acquisition date, the acquirer recognises and measures the identifiable assets acquired and liabilities assumed at their fair values. This is the purchase price allocation (PPA).
The Recognition Criteria
For an asset or liability to be recognised at the acquisition date, it must:
Meet the definition of an asset or liability in the Conceptual Framework at the acquisition date. Not necessarily have been recognised by the acquiree.
The second point is significant. An acquiree may have internally generated intangible assets (customer relationships, trade names, technology) that it never recognised under IAS 38 because it generated them internally. The acquirer must recognise these at fair value in the PPA if they meet the identifiability criteria of IAS 38 (separable or arising from contractual rights).
This is how customer relationships appear on the acquirer's balance sheet even though the acquiree carried none. The same assets that IAS 38 prohibits recognising internally are required to be recognised when transferred in a business combination.
Measurement Exceptions
IFRS 3 requires fair value for identifiable assets and liabilities at the acquisition date, with specific exceptions:
Income taxes (IAS 12 applies): recognised and measured under IAS 12, not at fair value.
Employee benefits (IAS 19): recognised and measured under IAS 19.
Indemnification assets: measured on the same basis as the indemnified liability.
Share-based payment awards (IFRS 2): measured under IFRS 2.
Assets classified as held for sale (IFRS 5): measured at fair value less costs to sell.
Reacquired rights (such as a licence previously granted to the acquiree that is now reacquired): measured at the remaining contractual term, not at fair value of a new licence.
Deferred Tax on Fair Value Step-Ups
When the acquirer steps up the carrying amount of the acquiree's assets to fair value, a temporary difference arises between the accounting carrying amount (fair value) and the tax base (typically cost). A deferred tax liability is recognised on these step-ups at the acquisition date.
This creates an important dynamic in the goodwill calculation: the deferred tax liability on fair value step-ups of identifiable assets reduces the net fair value of identifiable net assets, which increases goodwill. The deferred tax is recognised even when it relates to goodwill itself (where permitted by local tax law to claim a tax deduction for goodwill).
Indian context: when an Indian company acquires a foreign subsidiary with significant intangible assets, the fair value of those intangibles (customer relationships, technology, trade names) creates temporary differences. The deferred tax rate applied to those differences is the rate applicable in the subsidiary's jurisdiction, not India's rate. A US technology acquisition with significant customer relationship intangibles may have deferred tax liabilities calculated at the US federal and state tax rate.
The Measurement Period
If the accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the acquirer reports provisional amounts. Within 12 months of the acquisition date (the measurement period), the acquirer can revise these provisional amounts retrospectively to reflect new information about facts and circumstances that existed at the acquisition date.
Adjustments made within the measurement period are retrospective: they adjust the goodwill or bargain purchase gain as if the final amounts had been known at the acquisition date. Adjustments after the measurement period are not permitted; any changes in the estimates are recognised prospectively.
The measurement period ends as soon as the acquirer receives the information it was seeking. It cannot extend indefinitely to 12 months simply to preserve optionality.
Acquisition-Related Costs
All costs directly related to the acquisition are expensed in the period incurred. Advisory fees, legal fees, due diligence costs, financial modelling costs, and investment banker fees are all expensed, not capitalised as part of the cost of the acquisition.
This differs from old Indian GAAP and from the treatment of directly attributable costs in asset acquisitions (which are capitalised). For a significant acquisition, the M&A advisory fees alone can run to hundreds of crores. Expensing these immediately affects the acquirer's reported profit in the year of acquisition.
The rationale: these costs relate to the transaction process, not to the assets acquired. The assets are measured at fair value regardless of what the acquirer spent to evaluate them.
Costs of registering and issuing equity instruments issued as consideration are not acquisition-related costs; they are equity transaction costs under IAS 32, charged to equity, not profit or loss.
Non-Controlling Interest (NCI): Two Measurement Options
When the acquirer does not acquire 100% of the acquiree, the NCI (the portion it does not own) must be measured at the acquisition date. IFRS 3 permits two methods, as an accounting policy choice that can be made acquisition by acquisition:
Fair value method (full goodwill): NCI is measured at its fair value at the acquisition date. This recognises goodwill attributable to both the acquirer's interest and the NCI's interest.
Proportionate share method (partial goodwill): NCI is measured at the NCI's proportionate share of the acquiree's identifiable net assets at fair value. Only the acquirer's share of goodwill is recognised.
The choice affects goodwill, NCI on the balance sheet, and the subsequent impairment test (as discussed in Post 40 on the partial goodwill grossing-up adjustment).
Indian example: Tata Motors acquiring 75% of a subsidiary. Under the fair value method, NCI is measured at what 25% of the subsidiary is worth as a minority stake (which includes a control premium discount, making NCI fair value less than simply 25% of the 100% enterprise value). Under the proportionate share method, NCI is 25% of the identifiable net assets at fair value, a simpler calculation.
Most Indian companies use the proportionate share method for simplicity, though the fair value method produces a balance sheet that more faithfully reflects the NCI's economic position.
Ind AS 103 vs IFRS 3: Key Differences
| Area | IFRS 3 | Ind AS 103 |
|---|---|---|
| Acquisition method: mandatory | Same | Same |
| Business definition | Same | Same |
| Concentration test (optional) | Same | Same |
| Acquirer identification | Same | Same |
| Acquisition date | Same | Same |
| Fair value of identifiable net assets | Same | Same |
| Measurement exceptions | Same | Same |
| Deferred tax on step-ups | Same | Same |
| Acquisition costs expensed | Same | Same |
| NCI: two options | Same | Same |
| Common control transactions | Outside scope | Outside scope; MCA has issued guidance on predecessor value method for common control transactions |
| Reverse acquisitions | Covered | Same |
| Pooling of interests (prohibited) | Same | Same |
| IASB project on common control | Ongoing; no final standard | Ind AS will align when IASB finalises |
The MCA's guidance on common control transactions is the most significant India-specific addition. Given the frequency of intragroup restructurings in Indian conglomerates, the predecessor value method is now accepted practice for common control transactions where both entities are under the same ultimate parent before and after the restructuring.
What Big 4 Auditors Focus On
Business vs asset acquisition determination. Auditors test whether the concentration test has been correctly applied (if used), and whether the full IPO/outputs/processes assessment has been documented for acquisitions not using the concentration test. Misclassifying a business combination as an asset acquisition avoids goodwill recognition and allows transaction cost capitalisation, both of which improve reported earnings. This is a known audit risk.
Acquisition date determination. Auditors test whether the acquisition date reflects the actual date control passed. A management team motivated to consolidate results from an earlier date (to include the acquiree's profitable Q4) may set the acquisition date earlier than the actual control date. Auditors review the legal documentation, regulatory approval timeline, and any board or shareholder approvals required before control could pass.
Completeness of identifiable intangibles in PPA. Auditors test whether all identifiable intangible assets have been captured in the purchase price allocation at fair value. Understating intangibles overstates goodwill. Auditors engage valuation specialists to independently assess whether the PPA has missed significant customer relationships, technology assets, or trade names.
Measurement period adjustments. Auditors verify that adjustments within the measurement period are retrospective and that they relate to information about facts at the acquisition date. Post-measurement period changes in estimates are prospective, not retrospective. Misclassifying post-acquisition adjustments as measurement period corrections restates goodwill when the restatement is not permitted.
Acquisition cost expensing completeness. Auditors test whether all acquisition-related costs have been expensed, not capitalised. A management team that capitalises due diligence costs as part of the investment in subsidiary overstates assets and understates expenses.
Dip IFRS Exam Angle
IFRS 3 produces some of the most calculation-intensive exam questions in Dip IFRS. The goodwill calculation, NCI measurement, and purchase price allocation each require precise numbers.
Most tested areas:
Business combination identification: given a transaction, determine whether it is a business combination (IFRS 3), an asset acquisition, or a common control transaction.
Acquirer identification: in a complex scenario (share exchange, reverse acquisition), identify the accounting acquirer using the indicators and the control-based assessment.
Acquisition date: given a timeline with agreement date, regulatory approval date, and closing date, determine when control passed and therefore when the acquisition date falls.
NCI measurement: calculate NCI using both fair value and proportionate share methods. Know that the choice affects goodwill.
Acquisition costs: know that advisory and legal fees are expensed, not capitalised. Know that share issue costs are equity transaction costs.
Common traps:
Capitalising acquisition-related costs as part of the investment. They are expensed immediately.
Using the agreement date as the acquisition date when regulatory approval was required for control. Acquisition date is when control actually passes.
Assuming the legal acquirer is always the accounting acquirer. In reverse acquisitions, the legal acquiree may be the accounting acquirer.
Not recognising internally generated intangibles of the acquiree that meet the IFRS 3 recognition criteria. The prohibition in IAS 38 on internal generation does not apply in a business combination.
FAQ
What is the difference between a business combination and a merger?
Legally, a merger involves two entities combining into one surviving entity. Economically, one entity is typically the acquirer and the other the acquiree, even in a merger. IFRS 3 applies regardless of the legal form: if one entity obtains control of a business, the acquisition method applies. There is no separate "merger accounting" under IFRS.
Can an entity acquire a business for zero consideration?
Yes. A business combination can occur without any consideration being transferred, for example through a contract alone (a court-ordered transfer or a statutory merger where no payment changes hands). In such cases, goodwill is measured as the fair value of the acquirer's interest in the acquiree minus the fair value of identifiable net assets.
Why are internally generated intangibles of the acquiree recognised in a business combination when they would not be recognised if developed internally?
IAS 38 prohibits recognising internally generated intangibles because the costs of generation are inseparable from the costs of running the business, and reliable measurement of those costs is not possible. In a business combination, the fair value of those intangibles is observable from the transaction: the acquirer is paying for them as part of the total consideration. The fair value provides reliable measurement, satisfying the recognition criteria that IAS 38 cannot satisfy for internally generated items.
How long does the measurement period last?
A maximum of 12 months from the acquisition date. It ends earlier if the acquirer receives the information it was seeking to complete the PPA. It cannot be extended simply to preserve flexibility.
Does IFRS 3 apply when an entity acquires an associate (less than controlling interest)?
No. IFRS 3 requires control as defined in IFRS 10. Acquiring an associate (typically 20-50% interest with significant influence but not control) is accounted for under IAS 28, not IFRS 3. The equity method applies, and no purchase price allocation or goodwill calculation is required under IFRS 3.
What happens if the acquiree has contingent liabilities at the acquisition date?
Contingent liabilities of the acquiree are recognised at the acquisition date if they are present obligations resulting from past events (even if outflow is not probable) and their fair value can be measured reliably. This is an exception to IAS 37's requirement for probable outflow: in a business combination, contingent liabilities that meet only the obligation and reliable measurement criteria are still recognised.
