Accounting for Business Combinations (Acquisitions)

Business combinations—often referred to as acquisitions or mergers—are transactions in which one company obtains control over another.
These transactions reshape the financial statements of both the acquiring and acquired entities, impacting reported assets, liabilities, goodwill, and future earnings.

Definition of a Business Combination

A business combination occurs when an acquirer gains control over a business, typically by purchasing a majority of the voting shares or net assets. Under both US GAAP (ASC 805) and IFRS (IFRS 3), the term "business" is broadly defined to include integrated sets of activities and assets capable of being managed to provide returns.


Identifying the Acquirer

Determining which entity is the acquirer is the first step in accounting for a business combination. The acquirer is generally the entity that obtains control, usually evidenced by the power to govern financial and operating policies, the ability to appoint the majority of the board, or holding the majority of voting rights.


Acquisition Date and Measurement Principle

The acquisition date is the point when the acquirer obtains control of the acquiree. All identifiable assets acquired and liabilities assumed are measured at fair value as of this date, regardless of the acquirer’s intent to use or dispose of those assets.


Recognition of Identifiable Assets and Liabilities

At the acquisition date, the acquirer must recognize, separately from goodwill:

  • All identifiable assets acquired

  • All liabilities assumed

  • Any noncontrolling interest in the acquiree

Assets and liabilities must be measured at their fair values, which may differ significantly from their previous book values in the acquiree’s records.


Goodwill and Bargain Purchases

Goodwill arises when the consideration transferred exceeds the fair value of the identifiable net assets acquired. Goodwill is recorded as an intangible asset and subject to annual impairment testing (not amortized).If the fair value of net assets acquired exceeds the consideration paid, a bargain purchase gain is recognized immediately in earnings.


Consideration Transferred

The total consideration in a business combination includes cash paid, the fair value of shares issued, contingent payments, and the fair value of any assets or liabilities transferred as part of the deal. Future or contingent consideration is measured at fair value at the acquisition date and may require subsequent remeasurement.


Noncontrolling Interest

If the acquirer obtains less than 100% of the acquiree, a noncontrolling interest (NCI) is recognized. NCI represents the portion of the equity in the subsidiary not attributable to the parent company and is reported within equity on the consolidated balance sheet.


Acquisition-Related Costs

Transaction costs, such as legal, accounting, or advisory fees, are expensed as incurred and not included in the consideration transferred or the fair value of assets acquired.


Subsequent Measurement and Adjustments

After the acquisition date, the acquirer may adjust provisional fair values of assets and liabilities during the measurement period (up to one year) as additional information becomes available. After this period, changes are generally recognized in earnings.


Presentation and Disclosure

Business combinations must be presented in the consolidated financial statements. Disclosures should include details of the acquisition, the fair values of assets and liabilities acquired, the amount of goodwill or gain recognized, and the reasons for the combination. These disclosures provide stakeholders with a comprehensive view of the transaction’s financial impact.


Relevant Accounting Standards

  • US GAAP: ASC 805 – Business Combinations

  • IFRS: IFRS 3 – Business Combinations

Both frameworks require the acquisition method, fair value measurement, and detailed disclosures.
