Goodwill and Non-Controlling Interest in Consolidation
Updated 11 October 2026 · Fact-checked
Goodwill on acquisition is the consideration transferred plus the non-controlling interest at acquisition, minus the fair value of the subsidiary's identifiable net assets. NCI is measured either at fair value (full goodwill) or at its proportionate share of net assets (partial goodwill). The method chosen changes both goodwill and NCI.
Understand Goodwill and Non-Controlling Interest
When a parent buys control of a subsidiary, it usually pays more than the book value of the subsidiary's net assets. The extra amount is mostly goodwill. IFRS 3 says you measure goodwill as a balancing figure at the acquisition date.
The parent controls 100% of the subsidiary's assets and liabilities, even if it owns less than 100% of the shares. So consolidated statements include all of the subsidiary's net assets. The part of the subsidiary not owned by the parent is the non-controlling interest (NCI). It is shown in equity.
IFRS 3 gives a choice for measuring NCI at acquisition. Proportionate method (partial goodwill): NCI = NCI % × fair value of net assets. Goodwill then only reflects the parent's share. Fair value method (full goodwill): NCI = fair value of the NCI shares at acquisition date, usually the share price × number of shares held by NCI. Goodwill then includes the NCI's share of goodwill.
The net assets are always at fair value at acquisition, not book value. So you must first adjust for any fair value differences given in the question. Share capital plus reserves at acquisition, plus fair value adjustments, gives net assets at acquisition.
After acquisition, NCI grows by its share of the subsidiary's post-acquisition profit. Under the fair value method, goodwill impairment is also shared with NCI. That is covered in the impairment topics, but you should know NCI is not a fixed number.
Key rules to remember
- Goodwill
- Goodwill = Consideration transferred + NCI at acquisition − Fair value of identifiable net assets at acquisition
- Use this one layout for both methods. Only the NCI figure changes.
- NCI at acquisition (proportionate)
- NCI = NCI % × fair value of net assets at acquisition
- Gives partial goodwill. No goodwill is attributed to NCI.
- NCI at acquisition (fair value)
- NCI = Number of NCI shares × subsidiary share price at acquisition
- Gives full goodwill. Use the value given in the question, not the parent's price paid per share.
- Net assets at acquisition
- Share capital + reserves at acquisition date + fair value adjustments
- Include any fair value uplift on assets, and deduct fair value reductions.
- NCI at reporting date
- NCI at acquisition + NCI % × post-acquisition profit of subsidiary (− NCI share of goodwill impairment under the fair value method)
- Adjust the post-acquisition profit for fair value depreciation and unrealised profit where relevant.
- Consideration transferred
- Cash + fair value of shares issued + fair value of deferred consideration
- Contingent consideration is also included at fair value. Acquisition costs are expensed, not included.
How to solve Goodwill and Non-Controlling Interest questions
Use the same layout for every goodwill and NCI question. Read which NCI method is required before you start.
- 1Identify the acquisition date, the percentage acquired and the percentage held by NCI.
- 2Work out consideration transferred: cash, shares issued at fair value and deferred consideration at present value. Exclude acquisition costs.
- 3Decide the NCI method. If the question gives a share price for NCI shares and asks for fair value, use it. Otherwise use the proportionate share of net assets.
- 4Calculate net assets at acquisition: share capital plus reserves at the acquisition date plus fair value adjustments.
- 5Set out the goodwill working: consideration, plus NCI, minus net assets. Write each line with a label.
- 6Calculate NCI at the reporting date: NCI at acquisition plus its share of post-acquisition profits, less its share of any goodwill impairment if full goodwill is used.
- 7Carry goodwill (less any impairment) to non-current assets and NCI to equity in the statement of financial position.
Quickest way: The goodwill proforma
When to use it: Use it in Section C and in OT cases whenever you need goodwill or NCI at acquisition.
- Write three lines: Consideration, NCI, Net assets (negative). Leave space under each.
- Fill in consideration first. Check whether it is cash only or includes shares or deferred amounts.
- Compute net assets at acquisition in a side working. Do not use current-year reserves by mistake.
- Fill NCI: NCI % × net assets, or the given fair value.
- Sum the three lines for goodwill. If the answer is negative, recheck the figures before calling it a bargain purchase gain.
- In OT questions, only calculate the line that is asked for. Check which method is stated.
Common mistakes in Goodwill and Non-Controlling Interest
Using book value of net assets instead of fair value at acquisition.
Students take the subsidiary's equity from the statement of financial position and forget the fair value note.
Fix: Always scan the question for fair value adjustments and add them to net assets before calculating goodwill.
Using reserves at the reporting date rather than at the acquisition date.
The reporting-date figure is the first one visible in the question.
Fix: Find the date of acquisition and use the reserves at that date. Underline it in the question.
Using the parent's cost per share as the NCI fair value.
Both are share prices, so they look interchangeable.
Fix: Use the NCI share value given for the subsidiary. The parent's price often includes a control premium.
Including acquisition costs in consideration.
Students treat all costs of the purchase as cost of investment.
Fix: Under IFRS 3 these costs are expensed to profit or loss. Leave them out of goodwill.
Ignoring the time value of deferred consideration.
The amount payable later is simply added at its face value.
Fix: Discount deferred consideration to present value at the rate given, then add it to consideration.
Taking all of the goodwill impairment to the parent when full goodwill is used.
Students forget that NCI holds part of the goodwill.
Fix: Under the fair value method, share the impairment between parent and NCI in the ownership ratio. Under the proportionate method, the parent bears all of it.
Worked examples
Example 1
Parent acquired 80% of Sub on 1 January for ₹10,00,000 cash. At that date Sub's share capital was ₹2,00,000 and retained earnings were ₹6,00,000. The fair value of Sub's net assets equalled book value. Calculate goodwill using the proportionate method and the NCI at acquisition.
Show the solution
- Net assets at acquisition = ₹2,00,000 + ₹6,00,000 = ₹8,00,000.
- NCI = 20% × ₹8,00,000 = ₹1,60,000.
- Goodwill = ₹10,00,000 + ₹1,60,000 − ₹8,00,000 = ₹3,60,000.
Answer: Goodwill is ₹3,60,000 and NCI at acquisition is ₹1,60,000.
Example 2
Parent acquired 75% of Sub on 1 April for ₹15,00,000. Sub had 4,00,000 shares in issue. The market price of a Sub share at that date was ₹4. At acquisition Sub's net assets at book value were ₹12,00,000, and land with a book value of ₹2,00,000 had a fair value of ₹3,00,000. Calculate goodwill under the fair value method and under the proportionate method.
Show the solution
- Fair value of net assets = ₹12,00,000 + ₹1,00,000 uplift = ₹13,00,000.
- NCI shares = 25% × 4,00,000 = 1,00,000 shares.
- Fair value method: NCI = 1,00,000 × ₹4 = ₹4,00,000.
- Goodwill (full) = ₹15,00,000 + ₹4,00,000 − ₹13,00,000 = ₹6,00,000.
- Proportionate method: NCI = 25% × ₹13,00,000 = ₹3,25,000.
- Goodwill (partial) = ₹15,00,000 + ₹3,25,000 − ₹13,00,000 = ₹5,25,000.
- Check: the difference of ₹75,000 equals NCI's share of goodwill (₹4,00,000 − ₹3,25,000).
Answer: Goodwill is ₹6,00,000 under the fair value method (NCI ₹4,00,000) and ₹5,25,000 under the proportionate method (NCI ₹3,25,000).
Exam tips
- Read the question for the NCI method. If it gives a share price for the NCI, the examiner usually expects the fair value method.
- Always show the goodwill working with labelled lines. Method marks are given in Section C even if one figure is wrong.
- In OT questions, one wrong input makes the whole answer score zero. Check fair value adjustments and the acquisition-date reserves before you select an option.
- Remember that goodwill is not amortised. It is tested for impairment annually, so a later part of the question may ask for the impairment effect on NCI.
- Keep your goodwill working and your NCI working separate. You will need the acquisition figures again for the consolidated statement of financial position.

Goodwill and Non-Controlling Interest: frequently asked questions
What is the difference between full and partial goodwill?
Full goodwill uses the fair value of NCI at acquisition, so goodwill includes the NCI's share. Partial goodwill uses NCI's proportionate share of net assets, so goodwill relates only to the parent's holding. Net assets and consideration are the same under both.
How do I calculate NCI at fair value?
Multiply the number of shares held by the NCI by the subsidiary's share price at the acquisition date. Use the figure the question gives. This is normally different from the price the parent paid per share.
Does the NCI method change the consolidated profit?
Not at acquisition. It changes goodwill and NCI in the statement of financial position. If goodwill is impaired later, the fair value method shares the impairment with NCI, which changes how profit is split between parent and NCI.
What if goodwill comes out negative?
A negative figure is a bargain purchase. Reassess that all assets and liabilities have been identified and measured correctly. If it still remains negative, IFRS 3 requires the gain to be recognised in profit or loss in the year of acquisition.
