Ind AS 103 Business Combination and the Acquisition Method

Updated 11 October 2026 · Fact-checked

A business combination is a transaction in which an acquirer obtains control of one or more businesses. Ind AS 103 requires the acquisition method: identify the acquirer, fix the acquisition date, recognise identifiable assets and liabilities at fair value, then measure goodwill or a bargain purchase gain. Common control deals use pooling of interests instead.

Understand Business Combination Concepts and Ind AS 103

A business combination is a transaction or event in which an acquirer obtains control of one or more businesses. What is acquired must be a business, meaning an integrated set of activities and assets that can be run to provide a return. Buying a single machine is an asset purchase, not a business combination.

A combination can take several legal forms. One company may buy the shares of another, so the target becomes a subsidiary. One company may buy the net assets of another. Two companies may merge into a new company. The legal form does not change the accounting idea: someone gained control of a business. Ind AS 103 looks at substance, not form.

For most combinations Ind AS 103 requires the acquisition method. You identify the acquirer, determine the acquisition date, recognise and measure the identifiable assets acquired and liabilities assumed (generally at fair value), recognise any non-controlling interest, and then compute goodwill or a gain on a bargain purchase. The acquirer is the entity that obtains control. The acquisition date is the date it obtains control, which is usually the closing date but can be earlier or later if a written agreement says so.

Business combinations of entities under common control are different. Ind AS 103 Appendix C covers them. They include transfers of subsidiaries or businesses between entities within a group. The same party controls all combining entities before and after, so nothing really changes for the group. Appendix C requires the pooling of interests method, with carrying amounts and no fair value adjustments. IFRS 3 excludes such combinations from its scope, and Ind AS 103 fills the gap through Appendix C.

So your first decision in any question is simple: is this a common control combination or not? If yes, use pooling at carrying amounts. If no, use the acquisition method at fair values.

Key rules to remember

Goodwill (acquisition method): Goodwill = Consideration transferred + Non-controlling interest + Fair value of previously held interest − Net identifiable assets at fair value; A negative result is a bargain purchase gain, recognised after reassessing the identification and measurement of assets and liabilities.
Net identifiable assets: Fair value of identifiable assets acquired − Fair value of liabilities assumed; Includes identifiable intangibles not in the target's books. Goodwill already in the target's books is excluded.
Method for common control (Appendix C, para 8): Common control combination → pooling of interests method; Assets and liabilities at carrying amounts; no fair value adjustments; only adjustments to harmonise accounting policies (para 9).
Difference in common control (Appendix C, para 12): Share capital issued + additional consideration − Share capital of transferor → transferred to capital reserve; Present it separately from other capital reserves with disclosure of nature and purpose. Securities are recorded at nominal value (para 10).
Reserves in pooling (Appendix C, paras 11 and 12): Identity of reserves preserved; transferor's retained earnings aggregated with transferee's, or transferred to General Reserve, if any; Reserves available for dividend before the combination remain available after it.

How to solve Business Combination Concepts and Ind AS 103 questions

Use this order for any question on business combination concepts. It keeps you on the right method and earns step marks.

1Check that the target is a business, not a group of assets. If it is only assets, treat it as an asset purchase.
2Decide whether all combining entities are under common control of the same party before and after. If yes, move to the pooling method of Appendix C.
3If not under common control, identify the acquirer: who obtains control? Look at voting rights, who issues the shares or pays cash, board composition, relative size and who initiates the deal.
4Fix the acquisition date, which is the date control passes. Use it for fair values and for including results.
5Measure identifiable assets and liabilities at fair value, including intangibles not previously recognised, and recognise non-controlling interest.
6Compute goodwill using the formula. If negative, reassess and then record a bargain purchase gain.
7State the treatment of costs and disclosures briefly, and give a clear conclusion.

Quickest way: Two-question screen

When to use it: Use it for MCQs and short theory questions asking which method applies or who the acquirer is.

Ask one: is a business acquired and does one party gain control? If no, it is not a business combination.
Ask two: is the same party in control of all combining entities before and after? If yes, pooling at carrying amounts. If no, acquisition method at fair value.
For the acquirer, pick the entity that gains control. Where shares are exchanged, the issuer is usually the acquirer, but check for a reverse acquisition by looking at who ends up with majority voting rights.
For goodwill, do the arithmetic in one line: consideration plus NCI minus fair value of net assets.

Common mistakes in Business Combination Concepts and Ind AS 103

Applying fair values to a common control combination.
Students learn the acquisition method first and use it for every merger.
Fix: Test for common control first. Appendix C para 9 says assets and liabilities are at carrying amounts, with no fair value adjustments.
Assuming a partly owned subsidiary is not under common control.
Students think minority shareholders break the group link.
Fix: Appendix C para 4 says the extent of non-controlling interests is not relevant, as a partially-owned subsidiary is still under the parent's control.
Treating the legal acquirer as the accounting acquirer every time.
The company issuing shares looks like the buyer.
Fix: Look at who obtains control. In a reverse acquisition the issuer can be the accounting acquiree. Check voting rights after the deal.
Using the signing date or the payment date as the acquisition date by default.
Students link the date to the cash flow rather than to control.
Fix: The acquisition date is when the acquirer obtains control. Read the facts to see when that happens.
Including the target's existing goodwill in net identifiable assets.
Students copy the balance sheet total without adjusting.
Fix: Remove old goodwill, add identifiable intangibles at fair value, then compute new goodwill.
Recording the difference in a common control deal as goodwill.
The same gap arises in both methods, so students reuse the label.
Fix: Under Appendix C para 12 the difference goes to capital reserve, shown separately from other capital reserves with its nature and purpose disclosed.

Worked examples

Example 1

Meera Textiles Ltd acquires 100% of Kaveri Mills Ltd on 1 October for cash of ₹9,00,000. Kaveri's identifiable assets have a fair value of ₹12,00,000 and its liabilities have a fair value of ₹4,00,000. Meera Textiles and Kaveri Mills are independent. Compute goodwill and name the method.

Show the solution

The companies are independent, so there is no common control. The acquisition method applies.
Net identifiable assets at fair value = ₹12,00,000 − ₹4,00,000 = ₹8,00,000.
There is no non-controlling interest, as 100% is acquired, and no previously held interest.
Goodwill = ₹9,00,000 + ₹0 + ₹0 − ₹8,00,000 = ₹1,00,000.

Answer: Acquisition method applies. Goodwill is ₹1,00,000.

Example 2

Sagar Ltd holds 80% of Tapti Ltd and 70% of Yamuna Ltd. Sagar Ltd decides that Yamuna Ltd will take over the business of Tapti Ltd by issuing its own shares to Tapti's shareholders. Tapti's share capital is ₹5,00,000. Yamuna issues shares of nominal value ₹6,00,000 for this. The question asks: which method applies, and how is the difference treated?

Show the solution

Sagar Ltd controls both entities before and after the transaction. Under Appendix C para 3, transfers of businesses between group entities are common control combinations. The partial holdings do not matter (para 4).
Para 8 requires the pooling of interests method. Assets and liabilities are taken at carrying amounts, with no fair value adjustments (para 9).
Securities are recorded at nominal value (para 10), so the share capital issued is ₹6,00,000.
Difference = ₹6,00,000 issued − ₹5,00,000 transferor's share capital = ₹1,00,000.
Under para 12, this difference is transferred to capital reserve. It is presented separately from other capital reserves, with its nature and purpose disclosed.

Answer: Pooling of interests applies. The ₹1,00,000 excess is debited as a reduction in reserves (capital reserve adjustment) because issued capital exceeds transferor capital, and shown separately with disclosure. Reserves of Tapti keep their identity.

Exam tips

Begin every answer by classifying the deal as common control or not. This one line decides the method and earns marks.
Quote the paragraph idea in plain words, such as 'carrying amounts, no fair value adjustments, reserves keep their identity'. Examiners reward the correct rule.
For acquirer-identification questions, list the facts you used: voting rights, who pays or issues shares, board control, relative size. Then state a conclusion.
In MCQs, watch the words 'partially owned' and 'not consolidated'. Appendix C paras 4 and 5 say neither changes whether common control exists.
Show the goodwill formula in full, even when the arithmetic is short.

Business Combination Concepts and Ind AS 103: frequently asked questions

What is a business combination under Ind AS 103?

It is a transaction or event in which an acquirer obtains control of one or more businesses. What is acquired must be a business, not just a group of assets. The legal form, such as share purchase or merger, does not matter.

What is the acquisition method under Ind AS 103?

It is the method used for business combinations outside common control. You identify the acquirer and the acquisition date, measure identifiable assets and liabilities at fair value, recognise non-controlling interest, and compute goodwill or a bargain purchase gain.

How do you identify the acquirer?

The acquirer is the entity that obtains control of the other. Check voting rights after the deal, who pays cash or issues shares, board composition, relative size and who started the transaction. In a reverse acquisition, the legal issuer of shares may be the accounting acquiree.

How does a common control combination differ from an acquisition?

A common control combination is accounted for using pooling of interests under Appendix C. Carrying amounts are used, no fair values are applied, and reserves keep their identity. An acquisition uses fair values and can create goodwill.
