Common Control Business Combinations and Pooling of Interests Method

Updated 11 October 2026 · Fact-checked

A common control business combination is one where the same party controls all combining entities before and after the deal, and that control is not temporary. Ind AS 103 Appendix C requires the pooling of interests method: carry assets and liabilities at book values, restate comparatives, and record no goodwill or bargain gain.

Understand Common Control Business Combinations (Appendix C)

A common control business combination is a combination in which all the combining entities or businesses are ultimately controlled by the same party or parties both before and after the combination, and that control is not transitory. A typical case is a parent merging its two subsidiaries, or a subsidiary merging into the parent.

The reason for a special method is simple. No outside party is bought. The group's economic resources stay the same. Only their legal home changes. So fair values and goodwill would show a gain or cost that does not exist. Ind AS 103 therefore keeps such combinations out of the acquisition method and Appendix C prescribes the pooling of interests method.

Under this method the transferee records the assets and liabilities of the transferor at their carrying amounts as they appear in the transferor's books. No fair value remeasurement is done. Accounting policies are aligned, and any adjustment for this is shown in reserves.

The reserves of the transferor are generally carried forward in the same form, for example the retained earnings, securities premium and other reserves. The identity of reserves is preserved. The difference between the amount recorded as share capital issued by the transferee, plus any other consideration, and the amount of share capital of the transferor is transferred to capital reserve and shown separately from other capital reserves. This applies in all cases. If the difference is a debit (consideration is more than the transferor's share capital), the capital reserve is a debit balance. Appendix C does not provide for adjusting it against other reserves. A balance of the transferor's retained earnings is carried into the transferee's retained earnings.

The financial information in the statements for periods before the combination is restated as if the combination had occurred from the beginning of the preceding period presented, irrespective of the actual date. However, if the business was under common control only from a later date, the restatement is made only from that date. Costs of the combination are expensed as incurred, not capitalised.

Key rules to remember

Test for common control: Same party controls all combining entities before AND after, and control is not transitory; If this fails, use the acquisition method of Ind AS 103 instead.
Measurement of assets and liabilities: Recorded at carrying amounts in the transferor's books; no fair value remeasurement; No new goodwill is recognised. Items are carried as they appear in the transferor's books; policy alignment adjustments go to reserves.
Capital reserve on combination: Capital reserve = Share capital of transferor − (Face value of shares issued + other consideration paid); The difference always goes to capital reserve and is shown separately from other capital reserves. If the result is positive, it is a credit. If it is negative, it stays as a debit balance in capital reserve. It is not adjusted against other reserves. Reserves of the transferor are otherwise preserved in the same form.
Net assets taken over: Net assets = Book value of assets − Book value of liabilities; Use this to cross-check that the reserves and capital reserve entries balance.
Comparatives: Restate financials as if combined from the beginning of the preceding period presented; Use the later date if common control began later.
Combination costs: Expense as incurred; Do not add to assets or reserves.

How to solve Common Control Business Combinations (Appendix C) questions

Use this order for any question on common control combinations. It keeps entries tied to the Appendix C logic.

1Check the facts: is the same party in control of both entities before and after, and is the control more than transitory? If yes, apply Appendix C pooling.
2Write the transferor's balance sheet at carrying amounts. Ignore any fair value given in the question unless it is used only to fix the share exchange ratio.
3Compute net assets, split into share capital, reserves and liabilities taken over.
4Work out consideration: the face value of shares issued by the transferee plus any cash or other consideration.
5Find the difference between the transferor's share capital and the consideration. Put it to capital reserve in all cases. A debit difference stays as a debit balance in capital reserve.
6Carry forward the transferor's reserves in the same form; make any policy alignment adjustment through reserves.
7Eliminate inter-company balances such as mutual loans or investments by the transferee in the transferor's shares.
8Prepare the combined balance sheet, restate comparatives from the required date, and expense deal costs.

Quickest way: Add everything at book value, then settle the capital difference

When to use it: Use when the question asks only for the post-merger balance sheet or journal entries and gives book values.

Confirm common control in one line.
Add each line of the two balance sheets at book value.
Cancel inter-company items.
Replace the transferor's share capital with the shares issued by the transferee, at face value.
Put the difference to capital reserve, as a credit if positive and a debit balance if negative.
Check that total assets equal total equity and liabilities.

Common mistakes in Common Control Business Combinations (Appendix C)

Recording the transferor's assets at fair value
Students carry over habits from the acquisition method.
Fix: In pooling, use carrying amounts only. Use fair value only for the exchange ratio if asked.
Recognising goodwill or a bargain purchase gain
Students compare consideration with net assets as in Ind AS 103 main text.
Fix: No goodwill or gain arises. The difference goes to capital reserve.
Computing the difference using the fair value or the market value of shares issued
The question gives a market price of the shares.
Fix: Take the face value of shares issued as the amount recorded and compare it with the transferor's share capital.
Not restating comparatives
Students focus only on the closing balance sheet.
Fix: State that prior period figures are restated as if the combination took place from the beginning of the preceding period presented, or from when common control began if later.
Capitalising merger costs
Costs look like part of the price paid.
Fix: Expense them in profit or loss as incurred.
Wiping out the transferor's reserves, or writing a debit difference off against them
Students treat them as pre-acquisition profits, as in the acquisition method, or try to clear a negative capital reserve.
Fix: Carry the reserves forward in the same form. The capital difference goes only to capital reserve, even if it is a debit.

Worked examples

Example 1

P Ltd holds 100% of A Ltd and B Ltd. A Ltd merges into B Ltd. A Ltd's books: share capital ₹50,00,000, general reserve ₹20,00,000, retained earnings ₹10,00,000, liabilities ₹30,00,000, assets ₹1,10,00,000. B Ltd issues shares of face value ₹60,00,000 to P Ltd as consideration. Show the accounting treatment.

Show the solution

Common control exists: P Ltd controls both before and after. Apply pooling of interests.
Net assets of A Ltd = ₹1,10,00,000 − ₹30,00,000 = ₹80,00,000, which equals 50,00,000 + 20,00,000 + 10,00,000.
B Ltd records assets of ₹1,10,00,000 and liabilities of ₹30,00,000 at carrying amounts.
Consideration at face value = ₹60,00,000.
Difference = Share capital of A Ltd ₹50,00,000 − ₹60,00,000 = −₹10,00,000, a debit.
The difference is recognised in capital reserve, so capital reserve is a debit balance of ₹10,00,000. Appendix C does not allow it to be adjusted against other reserves, so the general reserve stays at ₹20,00,000.
Retained earnings of ₹10,00,000 are carried forward unchanged into B Ltd's retained earnings.
Check: Net assets ₹80,00,000 = share capital ₹60,00,000 + capital reserve (₹10,00,000) + general reserve ₹20,00,000 + retained earnings ₹10,00,000 = ₹80,00,000.

Answer: No goodwill. Assets of ₹1,10,00,000 and liabilities of ₹30,00,000 are recorded at book value. Share capital issued is ₹60,00,000. The debit of ₹10,00,000 stays as a debit balance in capital reserve, shown separately. General reserve remains ₹20,00,000 and retained earnings ₹10,00,000.

Example 2

X Ltd and Y Ltd are subsidiaries of Z Ltd. Y Ltd merges into X Ltd. Y Ltd has share capital ₹40,00,000, retained earnings ₹15,00,000, liabilities ₹25,00,000 and assets ₹80,00,000. X Ltd issues shares of face value ₹30,00,000 to Z Ltd. Merger costs of ₹1,00,000 are paid in cash. Find the capital reserve and describe the treatment of costs.

Show the solution

Common control by Z Ltd before and after, so pooling applies.
Net assets of Y Ltd = ₹80,00,000 − ₹25,00,000 = ₹55,00,000, which equals ₹40,00,000 + ₹15,00,000.
Consideration at face value = ₹30,00,000.
Capital reserve = ₹40,00,000 − ₹30,00,000 = ₹10,00,000, a credit.
Retained earnings of ₹15,00,000 are carried forward into X Ltd's retained earnings.
Check: ₹30,00,000 share capital + ₹10,00,000 capital reserve + ₹15,00,000 retained earnings = ₹55,00,000 net assets.
Merger costs of ₹1,00,000 are charged to profit or loss as incurred.

Answer: Capital reserve is ₹10,00,000, shown separately. Retained earnings of ₹15,00,000 are carried forward. Merger costs of ₹1,00,000 are expensed. No goodwill arises.

Exam tips

Begin every answer by testing common control. It earns the first mark and justifies the method.
Write the contrast with the acquisition method in two or three lines: fair value and goodwill versus book value and reserves.
Show a balance check at the end of numerical answers. It protects marks if one entry is wrong.
State the restatement of comparatives in every theory or numerical answer.
Label the capital reserve as separate and say whether it is a credit or a debit.

Common Control Business Combinations (Appendix C): frequently asked questions

What is the difference between the acquisition method and the pooling of interests method?

The acquisition method measures the acquired net assets at fair value and recognises goodwill or a bargain purchase gain. The pooling method uses carrying amounts, recognises no goodwill, preserves the transferor's reserves and restates comparatives. Pooling applies to common control combinations.

Does Appendix C apply to a merger of a subsidiary into its parent?

Yes, if control by the same party exists before and after and is not transitory. A parent and its wholly or partly owned subsidiary are under common control of the parent. The pooling method is applied in such cases.

What happens to the difference between share capital issued and the transferor's share capital?

The difference is transferred to capital reserve and shown separately from other capital reserves. If the transferor's share capital is more than the amount issued, it is a credit. If the shares issued exceed the transferor's share capital, it is a debit balance in capital reserve. It is not adjusted against other reserves.

From which date are comparatives restated?

They are restated as if the combination had occurred from the beginning of the preceding period presented, regardless of the actual date. If common control began later than that, restate only from the date common control began.
