Reverse Acquisitions and Measurement Period Adjustments (Ind AS 103)

Updated 5 October 2026 · Fact-checked

A reverse acquisition occurs when the legal acquirer, which issues shares, is the accounting acquiree. Consideration is the fair value of shares the legal subsidiary would have issued to give the parent's owners the same ownership. Provisional amounts can be adjusted for acquisition-date facts within one year, with goodwill changing alongside.

Understand Reverse Acquisitions and Measurement Period Adjustments

In most business combinations the entity that issues shares or pays cash is the acquirer. In a reverse acquisition, it is not. The entity that issues the shares (the legal parent) is identified as the accounting acquiree. The entity whose owners end up in control (the legal subsidiary) is the accounting acquirer. You decide this by looking at who controls the combined entity: relative voting rights, board composition, senior management, relative size and who pays a premium. It is not decided by legal form.

This happens often when a private company gets listed by being acquired by a smaller listed shell. The listed company issues so many new shares to the private company's owners that those owners hold the majority. Ind AS 103 therefore treats the private company as the buyer, even though the listed company is the parent in law.

The consolidated financial statements are issued in the legal parent's name but are presented as a continuation of the legal subsidiary's financial statements. The subsidiary's assets and liabilities stay at their pre-combination carrying amounts. The parent's identifiable assets and liabilities are brought in at fair value under the acquisition method. Goodwill or a bargain purchase gain arises on the parent side. Retained earnings and other equity balances are those of the legal subsidiary before the combination. The share capital shown must reflect the legal parent's capital (number and type of shares), so the balancing figure goes to other equity.

The consideration is notional. No cash or shares go from the accounting acquirer. It is the fair value of the shares the legal subsidiary would have had to issue to give the legal parent's owners the same percentage in the combined entity. If the fair value of the legal parent's own shares is more reliably measurable, you can use that instead.

The second idea is the measurement period. Valuations are often not ready at the reporting date. The acquirer then reports provisional amounts for the items that are incomplete. For up to one year from the acquisition date, you adjust those amounts retrospectively when you get new information about facts that existed at the acquisition date. Goodwill moves in the opposite direction to the net assets adjusted. After the period ends, you revise accounting only to correct an error under Ind AS 8.

Key rules to remember

Hypothetical shares the accounting acquirer would issue: Shares to issue = (Shares held by accounting acquirer's owners ÷ their % in combined entity) − Shares held by accounting acquirer's owners; The % is the share of the combined entity held by the legal subsidiary's owners after the deal, as a decimal.
Consideration transferred in a reverse acquisition: Consideration = Hypothetical shares × Fair value per share of accounting acquirer; Use the fair value of the legal parent's shares instead if that is more reliably measurable. The two should broadly agree.
Goodwill / bargain purchase: Goodwill = Consideration − Fair value of identifiable net assets of the legal parent (accounting acquiree); NCI is not part of this computation. In a reverse acquisition, any NCI is the legal subsidiary's owners who did not exchange their shares. It is measured at its share of the legal subsidiary's pre-combination carrying amounts and shown within equity. A previously held interest in the acquiree does not arise in a reverse acquisition, so it is not considered. A negative result is a bargain purchase. Reassess identification and measurement first. After reassessment, if there is clear evidence that the purchase is a bargain purchase, recognise the gain in other comprehensive income and accumulate it in equity as capital reserve. Otherwise, recognise the gain directly in equity as capital reserve.
Consolidated equity amount: Consolidated equity = Pre-combination equity of legal subsidiary + Consideration (fair value); Where there is NCI, consolidated equity includes the NCI. Share capital shown is the legal parent's. Other equity is the balancing figure. Retained earnings are the legal subsidiary's pre-combination balance.
Non-controlling interest in a reverse acquisition: NCI = NCI's share % × Pre-combination carrying amount of legal subsidiary's net assets; Arises only if some owners of the legal subsidiary do not exchange their shares.
EPS before the combination date (reverse acquisition): Weighted average shares = Shares issued by legal parent to legal subsidiary's owners; After the acquisition date, use the legal parent's actual shares outstanding, weighted from that date. Restate comparative EPS using the legal subsidiary's earnings and the shares issued to its owners.
Measurement period rule: Adjust provisional amounts retrospectively only for new information about acquisition-date facts, within a maximum of 1 year from the acquisition date; Events after the acquisition date (for example, meeting a target) are not measurement period adjustments.

How to solve Reverse Acquisitions and Measurement Period Adjustments questions

Use this order for any problem on reverse acquisitions or provisional accounting. It keeps the numbers tied to the rule at each step.

1Identify the legal parent and legal subsidiary. Then use the facts (voting %, board, management, size) to decide who the accounting acquirer is. If the legal subsidiary's owners hold the majority after the share issue, it is a reverse acquisition.
2Compute the post-combination ownership. Shares issued to the subsidiary's owners ÷ (those shares + the parent's existing shares).
3Compute the consideration: first the hypothetical shares the legal subsidiary would issue, then multiply by its fair value per share. Cross-check with the parent's shares × its fair value per share, where the data allows.
4Measure the legal parent's identifiable assets and liabilities at fair value. Keep the legal subsidiary's at carrying amounts. Compute goodwill or bargain purchase gain.
5Build consolidated equity: subsidiary's pre-combination equity plus consideration (plus NCI, where there is any, for total equity). Show legal parent's share capital, and put the balancing figure in other equity. Retained earnings stay as the subsidiary's.
6Handle NCI (proportion of the subsidiary's carrying net assets) and EPS (shares issued to subsidiary's owners before the date, actual shares after).
7For provisional items, ask whether the new information relates to facts at the acquisition date and falls within one year. If yes, adjust the asset or liability, adjust goodwill, and revise comparatives including depreciation effects. If not, treat it as a post-acquisition event or an error.
8Conclude with a one-line check: net assets in the consolidated balance sheet must equal consolidated equity.

Quickest way: Three-line reverse acquisition shortcut

When to use it: Use when a numerical asks only for consideration, goodwill or consolidated equity and time is short.

Ownership % of subsidiary's owners = new shares issued ÷ total shares after issue. Hypothetical shares = subsidiary's shares ÷ % − subsidiary's shares.
Consideration = hypothetical shares × subsidiary's share fair value. Goodwill = consideration − fair value of parent's net identifiable assets.
Consolidated equity = subsidiary's equity + consideration (add NCI for total equity if there is any). Check by adding subsidiary's carrying net assets, parent's fair value net assets and goodwill. The two totals must match.

Common mistakes in Reverse Acquisitions and Measurement Period Adjustments

Treating the legal parent as the acquirer because it issued the shares
Students follow legal form, as in a normal acquisition.
Fix: Test who controls the combined entity after the issue. If the subsidiary's owners hold the majority and control the board, apply reverse acquisition accounting.
Measuring the subsidiary's assets at fair value and the parent's at carrying amount
The usual direction of the acquisition method is applied without flipping it.
Fix: Remember that the accounting acquirer's assets stay at carrying amounts. Only the accounting acquiree (legal parent) is re-measured to fair value.
Using the parent's actual shares issued as the consideration number
Confusion between legal share count and the notional number the subsidiary would have issued.
Fix: Compute hypothetical shares from ownership %. Or multiply the parent's own shares by their fair value if that is more reliable.
Showing the subsidiary's share capital in the consolidated balance sheet
Students carry over the subsidiary's equity line by line.
Fix: Show the legal parent's issued share capital (number and nominal value). Put the balancing figure into other equity. Keep the subsidiary's retained earnings.
Adjusting provisional amounts for events after the acquisition date
Any change in a fair value looks like a measurement period adjustment.
Fix: Adjust only for information about facts existing at the acquisition date. Later events go through profit or loss or the relevant standard.
Forgetting goodwill and comparatives when a provisional amount changes
Students adjust only the asset.
Fix: Change goodwill by the opposite amount. Revise comparative information, including extra depreciation, as if the accounting was complete at the acquisition date.

Worked examples

Example 1

P Ltd (listed) has 5,000 equity shares of ₹10 each, with fair value ₹60 per share. It acquires 100% of S Ltd's 6,000 shares of ₹10 each by issuing 15,000 shares to S Ltd's shareholders. The fair value of an S Ltd share is ₹150. S Ltd's equity before the deal: share capital ₹60,000 and retained earnings ₹4,40,000. P Ltd's identifiable net assets have a fair value of ₹2,80,000 (carrying amount ₹2,50,000). Compute the consideration, goodwill and consolidated equity, and say who the accounting acquirer is.

Show the solution

Total shares after issue = 5,000 + 15,000 = 20,000. S Ltd's owners hold 15,000 ÷ 20,000 = 75%. They control P Ltd, so S Ltd is the accounting acquirer and P Ltd the accounting acquiree. This is a reverse acquisition.
Hypothetical shares S Ltd would issue = 6,000 ÷ 0.75 − 6,000 = 8,000 − 6,000 = 2,000 shares.
Consideration = 2,000 × ₹150 = ₹3,00,000. Cross-check: 5,000 P shares × ₹60 = ₹3,00,000. It agrees.
Goodwill = ₹3,00,000 − ₹2,80,000 (fair value of P Ltd's net identifiable assets) = ₹20,000. The carrying amount of ₹2,50,000 is not used.
S Ltd's equity before the combination = ₹60,000 + ₹4,40,000 = ₹5,00,000. There is no NCI, as S Ltd's owners exchange 100% of their shares. Consolidated equity = ₹5,00,000 + ₹3,00,000 = ₹8,00,000.
Share capital shown = 20,000 × ₹10 = ₹2,00,000 (the legal parent's). Retained earnings = ₹4,40,000 (S Ltd's). Balancing other equity = ₹8,00,000 − ₹2,00,000 − ₹4,40,000 = ₹1,60,000.
Check: net assets = S Ltd's ₹5,00,000 + P Ltd's ₹2,80,000 + goodwill ₹20,000 = ₹8,00,000, equal to consolidated equity.

Answer: S Ltd is the accounting acquirer. Consideration is ₹3,00,000 and goodwill is ₹20,000. Consolidated equity is ₹8,00,000, made up of share capital ₹2,00,000, retained earnings ₹4,40,000 and other equity ₹1,60,000.

Example 2

X Ltd acquired 100% of Y Ltd on 1 October 2026 for ₹60,00,000. At 31 March 2027, the valuation of Y Ltd's building was incomplete. X Ltd used a provisional fair value of ₹40,00,000. Y Ltd's total identifiable net assets, including the building, were provisionally ₹50,00,000. The building has a remaining life of 20 years (straight line, nil residual). On 31 January 2028, the valuer reports that the building's fair value at 1 October 2026 was ₹48,00,000, based on conditions existing at that date. Separately, on 15 December 2027 Y Ltd lost a major customer because of a later market change. Show the accounting for X Ltd. Ignore deferred tax.

Show the solution

Provisional goodwill = ₹60,00,000 − ₹50,00,000 = ₹10,00,000. Depreciation for 6 months to 31 March 2027 = ₹40,00,000 ÷ 20 × 6/12 = ₹1,00,000.
The valuation is received on 31 January 2028, within one year of 1 October 2026. It concerns facts existing at the acquisition date. So it is a measurement period adjustment. It is recorded in the financial statements for the year ending 31 March 2028.
Building increases by ₹8,00,000 to ₹48,00,000. Net identifiable assets become ₹58,00,000. Goodwill = ₹60,00,000 − ₹58,00,000 = ₹2,00,000, a decrease of ₹8,00,000.
Revised depreciation for 6 months to 31 March 2027 = ₹48,00,000 ÷ 20 × 6/12 = ₹1,20,000. In the 2027-28 financial statements, the comparative figures for the year ended 31 March 2027 are revised, and the extra ₹20,000 of depreciation is adjusted in that comparative period. Annual depreciation for the year ending 31 March 2028 and later years is ₹48,00,000 ÷ 20 = ₹2,40,000.
The loss of the customer on 15 December 2027 arose from an event after the acquisition date. It is not a measurement period adjustment. Goodwill and the acquisition-date amounts stay unchanged. X Ltd assesses it under the relevant standard, for example impairment testing under Ind AS 36 for the cash-generating unit including goodwill.

Answer: In the 2027-28 financial statements, increase the building by ₹8,00,000 and decrease goodwill by ₹8,00,000, to ₹2,00,000. Revise the 2026-27 comparative depreciation from ₹1,00,000 to ₹1,20,000 (extra ₹20,000). The customer loss is not an adjustment to acquisition accounting.

Exam tips

Start every reverse acquisition answer with the identification of the accounting acquirer and the reason (voting %, board control). Marks are given for this reasoning.
Show the hypothetical share calculation line by line, and the cross-check with the parent's own shares and fair value, where data allows. Examiners reward the working even when the arithmetic slips.
In presentation questions, state clearly which figures are the subsidiary's carrying amounts and which are the parent's fair values. A one-line balance check is a good closing step.
For provisional accounting, state three tests in your answer: information about acquisition-date facts, within one year, and goodwill adjusted with comparatives revised. Then conclude.
In case-scenario MCQs, look for the trap word: an event after the acquisition date is not a measurement period adjustment. Since there is no negative marking, always attempt every MCQ.

Practice questions from Ind AS 103 Business Combinations

Reverse Acquisitions and Measurement Period Adjustments: frequently asked questions

How do I calculate consideration in a reverse acquisition?

Work out the ownership % of the legal subsidiary's owners after the deal. Find the shares the subsidiary would have had to issue so its existing owners hold that %, then multiply by its share fair value. If the legal parent's share fair value is more reliable, use that instead.

How long is the measurement period under Ind AS 103?

It ends when the acquirer gets the information it was seeking, or learns it cannot get more. It cannot be longer than one year from the acquisition date. Adjustments in that window are made retrospectively.

What happens to adjustments made after the measurement period ends?

You do not adjust acquisition accounting for new information. You change it only to correct an error, under Ind AS 8. Other later changes follow the relevant standard through profit or loss or equity.

Whose EPS is shown in consolidated statements after a reverse acquisition?

Before the acquisition date, the weighted average shares equal the shares the legal parent issued to the legal subsidiary's owners. After it, the actual shares of the legal parent are used. Comparatives are restated on the legal subsidiary's earnings and the shares issued to its owners.
