Ind AS 103 prescribes the accounting when an entity obtains control of one or more businesses — a business combination. It requires the acquisition method for virtually all combinations, under which the acquirer measures the identifiable assets acquired and liabilities assumed at fair value and recognises goodwill as a residual. Critically — and in sharp contrast to AS 14 — goodwill under Ind AS 103 is not amortised but tested for impairment, and there is no pooling of interests method for combinations of unrelated parties. This standard governs how acquisitions and mergers are reflected in the accounts.
Objective and scope
The objective is to improve the relevance, reliability, and comparability of the information that an entity provides in its financial statements about a business combination and its effects. It does so by establishing principles and requirements for how the acquirer recognises and measures the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree; recognises and measures goodwill or a gain from a bargain purchase; and determines what information to disclose. A business combination is a transaction or other event in which an acquirer obtains control of one or more businesses. The standard applies to transactions meeting the definition of a business combination but excludes, among other things, the formation of a joint arrangement and combinations of entities or businesses under common control (which are dealt with separately, using a pooling-type approach based on book values).
The acquisition method
Ind AS 103 requires each business combination to be accounted for by applying the acquisition method, which involves four steps:
Identifying the acquirer — one of the combining entities is identified as the acquirer, being the entity that obtains control of the acquiree. The guidance in Ind AS 110 on control is used.
Determining the acquisition date — the date on which the acquirer obtains control, generally the closing date.
Recognising and measuring the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree.
Recognising and measuring goodwill or a gain from a bargain purchase.
There is no pooling of interests method for combinations of unrelated parties — the acquisition method is mandatory.
Recognising and measuring identifiable assets and liabilities
As of the acquisition date, the acquirer recognises, separately from goodwill, the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree. The identifiable assets and liabilities are measured at their acquisition-date fair values. This can result in recognising assets and liabilities that the acquiree had not recognised in its own financial statements — notably intangible assets (such as brands, customer relationships, and technology) that are identifiable and measurable, which are recognised separately from goodwill. Some limited exceptions to the fair value measurement principle apply (for example, deferred taxes under Ind AS 12, employee benefits under Ind AS 19, and certain others).
Non-controlling interest (NCI) in the acquiree is measured either at fair value or at the NCI's proportionate share of the acquiree's identifiable net assets — a choice available on a transaction-by-transaction basis.
Goodwill and bargain purchase
Goodwill is recognised as of the acquisition date, measured as the excess of (a) the aggregate of the consideration transferred, the amount of any non-controlling interest, and (in a step acquisition) the acquisition-date fair value of the acquirer's previously held equity interest in the acquiree, over (b) the net of the acquisition-date fair values of the identifiable assets acquired and liabilities assumed. In other words, goodwill is the residual — the premium paid over the fair value of the identifiable net assets.
Crucially, goodwill under Ind AS 103 is not amortised. Instead, it is tested for impairment at least annually under Ind AS 36 (and whenever there is an indication of impairment). This is a fundamental difference from AS 14, which amortises goodwill (ordinarily within five years).
Where the net of the acquisition-date fair values of the identifiable assets and liabilities exceeds the consideration (plus NCI and any previously held interest) — a bargain purchase — the acquirer first reassesses whether it has correctly identified and measured everything, and then recognises the resulting gain in profit or loss on the acquisition date. (Under AS 14, such an excess is generally recognised as a capital reserve, not as a gain in profit or loss — another difference.)
Consideration transferred, contingent consideration, and measurement period
The consideration transferred is measured at fair value, calculated as the sum of the acquisition-date fair values of the assets transferred, the liabilities incurred to the former owners, and the equity interests issued by the acquirer. Contingent consideration (an obligation to transfer additional consideration if specified future events occur) is recognised at its acquisition-date fair value as part of the consideration; subsequent changes are accounted for depending on whether the contingent consideration is classified as equity (not remeasured) or as an asset or liability (generally remeasured through profit or loss). Acquisition-related costs (such as advisory, legal, and due diligence fees) are expensed as incurred, not included in the cost of the combination. If the initial accounting is incomplete at the reporting date, the acquirer reports provisional amounts and adjusts them during a measurement period (not exceeding one year from the acquisition date) as new information about facts and circumstances existing at the acquisition date is obtained.
Disclosure
The acquirer discloses information enabling users to evaluate the nature and financial effect of a business combination that occurs during the reporting period (or after the reporting date but before the financial statements are approved) — including the name and description of the acquiree, the acquisition date, the consideration transferred and its components, the amounts recognised for each major class of assets acquired and liabilities assumed, the goodwill (with a qualitative description of the factors making it up) or bargain-purchase gain, and the acquiree's revenue and profit or loss since the acquisition date (and, on a pro forma basis, as if the combination had occurred at the start of the period).
A brief illustration
Company A acquires 100% of Company B for ₹500 lakh. B's identifiable assets and liabilities, measured at acquisition-date fair value, net to ₹420 lakh (this includes recognising a customer-relationship intangible of ₹40 lakh that B never carried on its own books). Under the acquisition method, A recognises the identifiable net assets at ₹420 lakh and records goodwill of ₹80 lakh (the ₹500 lakh consideration less the ₹420 lakh net assets). That goodwill is not amortised; instead A tests it for impairment annually. A's ₹5 lakh of due diligence and legal fees are expensed, not added to the cost. Under AS 14, by contrast, if this were a purchase, goodwill would be amortised (ordinarily within five years), the acquisition might use book values rather than full fair values, and the customer-relationship intangible would generally not be separately recognised — illustrating how differently the two standards portray the same deal.
How Ind AS 103 compares with AS 14
The differences are substantial. AS 14 permits the pooling of interests method for amalgamations in the nature of merger and the purchase method for others, generally uses book values or fair values, and amortises goodwill (ordinarily within five years), recognising any excess of net assets over consideration as a capital reserve. Ind AS 103 mandates the acquisition method for all combinations of unrelated parties (no pooling), measures identifiable assets and liabilities at fair value (recognising intangibles separately from goodwill), does not amortise goodwill (impairment-tested under Ind AS 36), and recognises a bargain-purchase gain in profit or loss. Ind AS 103 also expenses acquisition-related costs, recognises contingent consideration at fair value, and provides a measurement period for provisional amounts. (Combinations under common control are the exception, dealt with outside Ind AS 103 using a pooling-type, book-value approach.) The treatment of goodwill (amortise vs impair) and the mandatory acquisition method are the headline differences.
Common pitfalls
Recurring issues include applying a pooling/book-value approach to a combination of unrelated parties (the acquisition method is mandatory); amortising goodwill (not permitted under Ind AS 103 — it is impairment-tested); failing to recognise identifiable intangibles separately from goodwill; including acquisition-related costs in the cost of the combination rather than expensing them; and not recognising or incorrectly accounting for contingent consideration.
Why this is cleaner on a unified system
Applying the acquisition method requires identifying and fair-valuing all of the acquiree's assets and liabilities (including previously unrecognised intangibles), computing goodwill, and — thereafter — testing that goodwill for impairment and tracking any contingent consideration. This is far more reliable when the acquired business's records and the acquirer's ledger can be brought together in connected systems with a consistent chart of accounts, so that the acquisition-date fair values, the resulting goodwill, and the ongoing impairment testing and disclosures draw on a single source of truth rather than being reconciled from disparate books.
