Group Accounts and Consolidation Basics for IAI Actuarial

Updated 11 October 2026 · Fact-checked

Group accounts present a parent and its subsidiaries as one economic entity. You add the parent's and subsidiaries' assets and liabilities line by line, remove the parent's investment and the subsidiary's pre-acquisition equity, record goodwill, and show the outside shareholders' share as non-controlling interest. Associates use the equity method instead.

Understand Group Accounts and Consolidation Basics

A group is a parent company and the companies it controls. Each company keeps its own accounts, but investors want to see the whole group as if it were one business. Consolidated accounts do this.

The type of investment decides the treatment. A subsidiary is an entity the parent controls. Control usually comes with holding more than 50% of the voting rights, but it is really about power over the entity and exposure to its returns. An associate is an entity where the investor has significant influence but not control. A holding of 20% to 50% of votes is the usual indicator, not a strict rule. A joint venture is a arrangement where parties share control and have rights to its net assets.

For a subsidiary you use full consolidation. You add 100% of the subsidiary's assets, liabilities, income and expenses to the parent's, even if the parent owns less than 100%. The part of the subsidiary's net assets and profit that belongs to outside shareholders is shown separately as non-controlling interest (NCI). Balances between group companies, such as intra-group loans, receivables and sales, are cancelled out.

The parent's investment in the subsidiary is replaced by the subsidiary's net assets. The difference is goodwill. Goodwill is what the parent paid (plus the NCI's share) above the fair value of the subsidiary's identifiable net assets at the date of acquisition. Only profits earned after acquisition belong in group reserves.

Associates and joint ventures are not added line by line. Under the equity method, the investment appears as one line in the balance sheet. It starts at cost and grows by the investor's share of the investee's post-acquisition profit. The share of profit appears as one line in the profit or loss statement.

Key rules to remember

Goodwill (full or proportionate method): Goodwill = Consideration paid + NCI at acquisition − Fair value of net assets of subsidiary at acquisition; NCI at acquisition is either its share of fair value of net assets (proportionate method) or its fair value (full goodwill method). State which method you use.
Net assets at acquisition: Net assets at acquisition = Share capital + Reserves at acquisition date (± fair value adjustments); Use fair values, not book values, for identifiable assets and liabilities.
Non-controlling interest at the reporting date: NCI = NCI at acquisition + NCI % × post-acquisition change in subsidiary's net assets; Equivalent to NCI % × subsidiary's net assets at the reporting date under the proportionate method, before any goodwill attributable to NCI.
Group reserves: Group reserves = Parent's reserves + Parent % × subsidiary's post-acquisition reserves − goodwill impairment charged to parent; Only post-acquisition profits are included.
Equity method carrying amount: Associate = Cost + Share % × post-acquisition profit of associate − dividends received − impairment; Shown as one line in non-current assets.
Unrealised profit on inventory: Provision = Profit margin × Intra-group inventory still held at year end; Deduct from group inventory and from group reserves (or split with NCI if the subsidiary sold the goods).

How to solve Group Accounts and Consolidation Basics questions

Use the same sequence for any consolidated balance sheet question. Set out workings in separate, labelled columns so you pick up method marks even if a number is wrong.

1Decide the relationship: subsidiary (control), associate (significant influence) or joint venture. This sets full consolidation or equity method.
2Work out the group structure: percentage held by the parent, percentage held by NCI, and the acquisition date.
3Calculate the subsidiary's net assets at acquisition and at the reporting date. Include fair value adjustments at both dates.
4Calculate goodwill using the formula. State whether NCI is measured proportionately or at fair value. Deduct any impairment.
5Calculate NCI at the reporting date and group reserves (post-acquisition profits only).
6Adjust for intra-group items: cancel balances, and remove unrealised profit in inventory.
7Add parent and subsidiary assets and liabilities line by line, replace the investment with goodwill, and finish with the group equity section. Check that the balance sheet balances.

Quickest way: Four-working shortcut for the consolidated balance sheet

When to use it: Use this in timed written questions when you must produce a consolidated balance sheet quickly.

Draw a net assets table for the subsidiary with two columns: at acquisition and at reporting date. The difference is post-acquisition profit.
Compute goodwill from the acquisition column in one line.
Compute NCI and group reserves from the reporting date column and the post-acquisition difference.
Do the intra-group adjustments last and post each to both sides, then add across line by line.

Common mistakes in Group Accounts and Consolidation Basics

Including the subsidiary's pre-acquisition profits in group reserves.
Students add the subsidiary's whole reserves to the parent's.
Fix: Only the parent's share of post-acquisition reserves belongs in group reserves. Pre-acquisition reserves are part of net assets bought and feed into goodwill.
Consolidating only the parent's percentage of the subsidiary's assets.
Students confuse full consolidation with proportionate consolidation.
Fix: Add 100% of the subsidiary's assets and liabilities. Show the outside share through NCI.
Using book value instead of fair value of net assets at acquisition.
The question gives fair value adjustments in a note and they are missed.
Fix: Read the notes first. Adjust net assets at acquisition, and adjust later depreciation if the fair value uplift is on a depreciable asset.
Forgetting to cancel intra-group balances and unrealised profit.
Students treat the balance sheet as a simple addition.
Fix: Tick off every intra-group receivable, payable and loan. Compute the unrealised profit on goods still in inventory and remove it.
Treating an associate like a subsidiary.
Both involve a share in another company.
Fix: For an associate, show one investment line using the equity method. Do not add its assets and liabilities, and do not show NCI.

Worked examples

Example 1

P Ltd bought 80% of S Ltd on 1 April for ₹5,00,000. At that date S Ltd had share capital of ₹2,00,000 and reserves of ₹1,50,000. Fair values equalled book values. NCI is measured at its proportionate share of net assets. Calculate goodwill.

Show the solution

Net assets of S at acquisition = 2,00,000 + 1,50,000 = ₹3,50,000.
NCI at acquisition = 20% × 3,50,000 = ₹70,000.
Goodwill = Consideration + NCI − Net assets = 5,00,000 + 70,000 − 3,50,000 = ₹2,20,000.

Answer: Goodwill is ₹2,20,000.

Example 2

Using the data above, at the reporting date S Ltd has share capital of ₹2,00,000 and reserves of ₹2,50,000. P Ltd's own reserves are ₹6,00,000. Goodwill has not been impaired. Calculate group reserves and NCI at the reporting date.

Show the solution

Post-acquisition reserves of S = 2,50,000 − 1,50,000 = ₹1,00,000.
P's share = 80% × 1,00,000 = ₹80,000.
Group reserves = 6,00,000 + 80,000 = ₹6,80,000.
S net assets at reporting date = 2,00,000 + 2,50,000 = ₹4,50,000.
NCI = 20% × 4,50,000 = ₹90,000. Check: 70,000 + 20% × 1,00,000 = ₹90,000.

Answer: Group reserves are ₹6,80,000 and NCI is ₹90,000.

Exam tips

Write down the method you use for NCI (proportionate or fair value). Markers give credit for stating assumptions.
Always show goodwill and NCI workings separately, so errors do not carry through unmarked.
In MCQs, check whether the question asks for a subsidiary or an associate before calculating anything.
Be ready to explain in words why control, not ownership percentage alone, decides consolidation.
Link the topic to ratio analysis: consolidation changes gearing and return measures, which a written question may ask you to comment on.

Group Accounts and Consolidation Basics: frequently asked questions

What is the difference between a subsidiary and an associate?

A subsidiary is controlled by the parent, so its assets and liabilities are added line by line. An associate is one where the investor has significant influence only, so it appears as a single investment line under the equity method.

What is non-controlling interest in consolidation?

It is the share of a subsidiary's net assets and profit that belongs to shareholders other than the parent. It is shown within equity in the consolidated balance sheet, separate from the parent's shareholders' equity.

How is goodwill calculated in a consolidation?

Add the consideration paid and the NCI at acquisition, then deduct the fair value of the subsidiary's identifiable net assets at the acquisition date. A positive result is goodwill.

Why are only post-acquisition profits included in group reserves?

Pre-acquisition profits were already part of what the parent paid for. Including them again would count the same value twice, so they go into the goodwill calculation instead.
