AS 21 lays down principles and procedures for preparing and presenting consolidated financial statements — the combined financial statements of a parent and its subsidiaries, presented as those of a single economic entity. When a company controls other companies, looking only at the parent's standalone accounts gives an incomplete picture; consolidation brings the whole group together so users can see the financial position and performance of the group as if it were one enterprise.
Objective and scope
The objective is to lay down principles and procedures for preparation and presentation of consolidated financial statements, which are intended to present financial information about a parent and its subsidiary(ies) as a single economic entity. Consolidated financial statements are presented by a parent that presents such statements (and, under the Companies Act, most parents are required to). The standard is applied in preparing consolidated financial statements for a group of enterprises under the control of a parent.
Control and the definition of a subsidiary
The concept of control is central. A subsidiary is an enterprise that is controlled by another enterprise (the parent). Control under AS 21 means one of two things: the ownership, directly or indirectly through subsidiary(ies), of more than one-half of the voting power of an enterprise; or control of the composition of the board of directors (in the case of a company) or the corresponding governing body so as to obtain economic benefits from its activities. So control can arise either from holding a majority of votes or from the power to control the board — the latter capturing situations where control exists even without a majority shareholding.
A parent consolidates all its subsidiaries, domestic and foreign, with limited exceptions (for example, where control is intended to be temporary because the subsidiary is acquired and held exclusively with a view to its subsequent disposal in the near future, or where the subsidiary operates under severe long-term restrictions that significantly impair its ability to transfer funds to the parent).
Consolidation procedures
Consolidated financial statements are prepared by combining the financial statements of the parent and its subsidiaries on a line-by-line basis, adding together like items of assets, liabilities, income, and expenses. Several adjustments are then made so that the result represents a single economic entity:
The cost of the parent's investment in each subsidiary and the parent's portion of equity of each subsidiary are eliminated at the date of acquisition. Any excess of the cost of the investment over the parent's share of the subsidiary's equity is recognised as goodwill; any excess of the parent's share of equity over the cost is recognised as a capital reserve.
Intra-group balances and intra-group transactions, and the resulting unrealised profits, are eliminated in full. Unrealised losses are also eliminated unless cost cannot be recovered. This prevents the group from showing profits or balances that arise merely from dealings between its own members.
Minority interest (the portion of the net results and net assets of a subsidiary attributable to interests not owned by the parent) is identified and presented separately from the parent shareholders' interests. Minority interest in the net income of the group is separately presented, as is minority interest in the net assets.
Consolidated financial statements are prepared using uniform accounting policies for like transactions and events; where this is impracticable, that fact is disclosed. The financial statements of the parent and subsidiaries used in consolidation are usually drawn up to the same reporting date.
Goodwill, minority interest, and disposals
Goodwill arising on consolidation represents the premium paid on acquiring the subsidiary over the fair value of the parent's share of net assets, and is presented as an asset. Minority interest represents the outside shareholders' stake in the subsidiaries and is presented in the consolidated balance sheet separately from liabilities and the parent's equity. When the parent disposes of a subsidiary, the results of the subsidiary are included in the consolidated statement of profit and loss up to the date of disposal, and the difference between the proceeds and the carrying amount of the net assets attributable to the parent is recognised as a gain or loss.
Disclosure
Disclosures include a list of subsidiaries with the proportion of ownership interest and, where different, the proportion of voting power held; the nature of the relationship where control exists other than through majority voting power; and the effect of the acquisition and disposal of subsidiaries during the period. Where a subsidiary is not consolidated, the reasons are disclosed.
A brief illustration
A parent company acquires 80% of a subsidiary for ₹100 lakh when the subsidiary's net assets are worth ₹110 lakh. The parent's share of the net assets is 80% of ₹110 lakh = ₹88 lakh; since it paid ₹100 lakh, goodwill of ₹12 lakh is recognised on consolidation. The remaining 20% of the subsidiary's net assets, ₹22 lakh, is shown as minority interest. In preparing the consolidated accounts, the parent adds its and the subsidiary's assets, liabilities, income, and expenses line by line, eliminates the ₹100 lakh investment against the parent's share of the subsidiary's equity, removes any intra-group sales and unrealised profits (for example, on goods the parent sold to the subsidiary that remain in stock), and presents the ₹12 lakh goodwill and the minority interest separately. The consolidated statements then portray the group as a single economic entity.
How AS 21 compares with Ind AS 110
AS 21 corresponds to Ind AS 110, Consolidated Financial Statements, and both require consolidation of controlled entities using similar line-by-line procedures and elimination of intra-group items. The most important difference is the definition of control. AS 21 defines control mechanically — more than half the voting power, or control of the composition of the board. Ind AS 110 uses a broader, principle-based definition: an investor controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. This can capture control in situations (such as through potential voting rights, contractual arrangements, or de facto control with less than a majority) that the AS 21 mechanical test might not. Two other differences: Ind AS 110 uses the term non-controlling interest (NCI) rather than minority interest and measures and presents it within equity; and goodwill on consolidation under the Ind AS framework (via Ind AS 103) is not amortised but tested for impairment, whereas the AS framework treats consolidation goodwill differently. So the frameworks share the consolidation mechanics but differ notably on what triggers consolidation and on the treatment of NCI and goodwill.
Common pitfalls
Recurring issues include failing to consolidate a subsidiary that is controlled through board composition rather than majority voting; not eliminating intra-group balances, transactions, and unrealised profits in full; incorrectly computing goodwill or capital reserve at the acquisition date; misclassifying or mismeasuring minority interest; and not using uniform accounting policies across the group.
Why this is cleaner on a unified system
Consolidation depends on combining the accounts of the parent and each subsidiary and reliably identifying and eliminating intra-group transactions and balances — far easier when the group's entities are maintained in connected systems with a consistent chart of accounts and clear tagging of inter-company dealings. When the underlying records share a single source of truth, aggregating line by line, eliminating intra-group items, and computing goodwill and minority interest is more straightforward than reconciling disparate ledgers across the group.
