Fair Value Adjustments and Pre/Post-Acquisition Reserves
Updated 11 October 2026 · Fact-checked
On acquisition you restate the subsidiary's identifiable net assets to fair value, which changes goodwill. Later, extra depreciation on the uplift reduces post-acquisition profit. Only the subsidiary's profits earned after acquisition, adjusted for these items, join group retained earnings. Pre-acquisition reserves are absorbed into the goodwill calculation.
Understand Fair Value Adjustments and Pre/Post-Acquisition Reserves
When a parent buys a subsidiary, IFRS 3 requires you to measure the subsidiary's identifiable assets and liabilities at fair value at the acquisition date. The subsidiary's own books usually show carrying amounts, which can differ. A building may be worth more than its book value. Inventory may be worth more than cost.
The difference is a fair value adjustment. You make it only on consolidation, in your working papers. The subsidiary does not change its own ledgers. The adjustment alters net assets at acquisition, so it alters goodwill. A fair value uplift reduces goodwill. A fair value reduction increases it.
The uplift does not stay still. If the asset is depreciable, the group must depreciate the higher value. The extra depreciation is charged against the group's figures each year after acquisition. If the asset is inventory, the uplift reverses through cost of sales once the inventory is sold. If the asset is land, there is no extra charge.
Pre-acquisition reserves are profits the subsidiary earned before the parent took control. The parent paid for them in the price, so they sit inside goodwill and are never added to group reserves. Post-acquisition reserves are profits earned after control passed. The group share of these goes into consolidated retained earnings.
The subsidiary's equity at acquisition is share capital plus reserves at that date. Net assets at acquisition equal that equity, plus or minus the fair value adjustments. The same adjustments are therefore carried into the net assets at the reporting date and into the post-acquisition movement.
Key rules to remember
- Fair value adjustment
- FV adjustment = fair value − carrying amount at acquisition date
- Positive is an uplift, negative is a reduction. Apply it to the subsidiary's net assets at acquisition and at the reporting date.
- Net assets at acquisition
- Share capital + reserves at acquisition date + FV adjustments
- Used in the goodwill calculation.
- Additional depreciation on uplift
- Uplift ÷ remaining useful life × years since acquisition
- Charge it in the subsidiary's post-acquisition profit. The cumulative total reduces net assets at the reporting date.
- Post-acquisition profit
- Subsidiary reserves at reporting date − reserves at acquisition − cumulative extra depreciation or inventory reversal
- Use the adjusted figure to get the parent's share.
- Group retained earnings
- Parent retained earnings + parent % × adjusted post-acquisition profit of subsidiary
- Also adjust for unrealised profit and goodwill impairment where given.
- Goodwill
- Consideration + NCI − fair value of net assets at acquisition
- NCI is measured at fair value or at its proportionate share of net assets.
How to solve Fair Value Adjustments and Pre/Post-Acquisition Reserves questions
Use the same layout every time. A structured working earns method marks even if a number is wrong.
- 1Read the scenario and note the acquisition date, the percentage held and the length of time since acquisition.
- 2List each fair value difference: asset, carrying amount, fair value and difference.
- 3Write the net assets table with columns for acquisition date and reporting date. Include share capital, reserves and the fair value adjustments.
- 4Work out the extra depreciation or inventory reversal. Reduce the reporting date net assets by the cumulative charge.
- 5Calculate goodwill using net assets at acquisition, including the adjustments.
- 6Calculate post-acquisition profit as the movement in net assets, which is the reporting date figure minus the acquisition figure. Take the parent's share for group retained earnings and the NCI share for NCI.
- 7Adjust the consolidated assets for the uplift less cumulative depreciation. Check that the statement of financial position balances.
Quickest way: Net assets table shortcut
When to use it: Use it in Section B or C questions where the subsidiary's data is given as share capital and reserves at two dates.
- Draw two columns: acquisition and reporting date.
- Enter share capital, retained earnings and the fair value adjustment in each column.
- Put the extra depreciation only in the reporting date column, as a negative.
- Subtract the columns to get post-acquisition movement. Use the total for goodwill (acquisition column) and for reserves and NCI (movement).
- Check that the uplifted asset in the consolidated statement of financial position equals the book value plus the uplift less depreciation.
Common mistakes in Fair Value Adjustments and Pre/Post-Acquisition Reserves
Ignoring the fair value adjustment in the goodwill calculation.
Students use the subsidiary's book equity because it is the number given first.
Fix: Always ask whether any asset or liability is not at fair value. Add the adjustment to net assets at acquisition.
Forgetting the extra depreciation on the uplift after acquisition.
The uplift is treated as a one-off entry at acquisition.
Fix: If the asset is depreciable, charge uplift ÷ remaining life for each year since acquisition. Reduce post-acquisition profit and reporting date net assets.
Adding the subsidiary's whole retained earnings to group reserves.
Students confuse the total balance with profit earned under the group's control.
Fix: Use only the post-acquisition movement. Pre-acquisition reserves belong in goodwill.
Using the wrong remaining life for the extra depreciation.
Students use the total life instead of the remaining life at acquisition.
Fix: Divide the uplift by the remaining useful life at the acquisition date. Then multiply by the years held.
Depreciating land or leaving inventory uplift in place.
All uplifts are treated the same.
Fix: Land is not depreciated. Inventory uplift reverses through cost of sales when the inventory is sold, so it has no effect on closing net assets once sold.
Giving all post-acquisition profit to the parent when there is a non-controlling interest.
Students forget the NCI share of adjusted profit.
Fix: Split the adjusted post-acquisition profit between parent and NCI using the ownership percentages.
Worked examples
Example 1
Parent buys 80% of Sub on 1 January 20X1 for ₹5,00,000. At that date Sub has share capital ₹1,00,000 and retained earnings ₹2,00,000. Sub's building has a carrying amount of ₹2,00,000 and a fair value of ₹2,60,000. Remaining life is 20 years. On 31 December 20X3 Sub's retained earnings are ₹3,50,000. NCI is measured at its proportionate share of net assets. Calculate goodwill and the group share of Sub's post-acquisition profit.
Show the solution
- Fair value uplift = ₹2,60,000 − ₹2,00,000 = ₹60,000.
- Net assets at acquisition = 1,00,000 + 2,00,000 + 60,000 = ₹3,60,000.
- NCI at acquisition = 20% × 3,60,000 = ₹72,000.
- Goodwill = 5,00,000 + 72,000 − 3,60,000 = ₹2,12,000.
- Extra depreciation per year = 60,000 ÷ 20 = ₹3,000. Over 3 years = ₹9,000.
- Post-acquisition profit = (3,50,000 − 2,00,000) − 9,000 = ₹1,41,000.
- Parent share = 80% × 1,41,000 = ₹1,12,800.
Answer: Goodwill is ₹2,12,000. The group share of Sub's adjusted post-acquisition profit is ₹1,12,800.
Example 2
Parent owns 60% of Sub, acquired on 1 April 20X2 when Sub's retained earnings were ₹80,000. Sub's inventory at that date had a carrying amount of ₹40,000 and a fair value of ₹55,000. All of that inventory was sold by 31 March 20X3. Sub's retained earnings at 31 March 20X3 are ₹1,40,000. Parent's own retained earnings are ₹3,00,000. Ignore goodwill impairment. Calculate group retained earnings.
Show the solution
- Inventory uplift = 55,000 − 40,000 = ₹15,000.
- The inventory has been sold, so the uplift reverses through cost of sales. Sub's reported profit is overstated relative to the group by ₹15,000.
- Post-acquisition movement = 1,40,000 − 80,000 = ₹60,000.
- Adjusted post-acquisition profit = 60,000 − 15,000 = ₹45,000.
- Parent share = 60% × 45,000 = ₹27,000.
- Group retained earnings = 3,00,000 + 27,000 = ₹3,27,000.
Answer: Group retained earnings are ₹3,27,000.
Exam tips
- Look for words such as fair value, valued at or worth in the scenario. They signal an adjustment you must make.
- Show the net assets table in every answer. Marks are given for the acquisition column even if later figures are wrong.
- In objective tests, check whether the question asks for goodwill, group reserves or NCI. Each uses a different column of the same table.
- Check the asset type. Buildings and plant create extra depreciation, land does not, and inventory reverses once sold.
- Use the remaining useful life at the acquisition date, not the total life, and count the exact months or years since acquisition.

Fair Value Adjustments and Pre/Post-Acquisition Reserves: frequently asked questions
Why are fair value adjustments made only on consolidation?
The subsidiary keeps its own records at its own carrying amounts. IFRS 3 requires the group to recognise the subsidiary's net assets at fair value at acquisition. You therefore adjust in the consolidation workings and not in the subsidiary's ledger.
What is the difference between pre-acquisition and post-acquisition profits?
Pre-acquisition profits were earned before the parent gained control. They are included in net assets at acquisition and therefore in goodwill. Post-acquisition profits were earned after control passed, and the group's share is added to consolidated retained earnings.
How do I treat extra depreciation on a fair value uplift?
Divide the uplift by the remaining useful life at acquisition. Charge that amount for each year since acquisition against the subsidiary's post-acquisition profit. Also reduce the consolidated asset by the cumulative total.
Does the fair value adjustment change the NCI?
Yes. NCI at acquisition is based on either fair value or a share of net assets. With the proportionate method, a higher fair value of net assets raises NCI. NCI also takes its share of the adjusted post-acquisition profit.
