17.1 Business Combinations

Key Takeaways

  • Under ASC 805, all acquisition-related transaction costs (legal, accounting, advisory fees) must be expensed as incurred and are not capitalized.
  • Costs to register and issue equity securities in a business combination are recorded as a reduction of the equity proceeds, debited to Additional Paid-in Capital (APIC).
  • Contingent consideration is recognized at its acquisition-date fair value and classified as either a liability or equity depending on the settlement mechanism.
  • Liability-classified contingent consideration must be remeasured to fair value at each reporting date, with changes recognized in earnings.
  • A bargain purchase occurs when the fair value of net identifiable assets acquired exceeds the consideration transferred, resulting in an immediate gain in earnings.

17.1 Business Combinations & The Acquisition Method (ASC 805)

Scope and Definition of a Business Combination

Under ASC 805 (Business Combinations), a business combination is defined as a transaction or other event in which an acquirer obtains control of one or more businesses. In practice, a reporting entity must first determine whether a transaction is the acquisition of a business or the acquisition of an asset. If it is the acquisition of an asset, the transaction is accounted for under other applicable standards (e.g., ASC 360), which do not allow for the recognition of goodwill and require transaction costs to be capitalized.

To qualify as a business, an acquired set of activities and assets must consist of, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs:

  1. Inputs: Any economic resource that creates, or has the ability to create, outputs when one or more processes are applied to it. Examples include active employees, intellectual property, raw materials, and equipment.
  2. Processes: Any system, standard, protocol, convention, or rule that, when applied to an input or inputs, creates or has the ability to create outputs. Examples include operational processes, intellectual property management, and billing systems. An administrative process (e.g., payroll, general ledger) generally is not considered substantive.
  3. Outputs: The results of inputs and processes applied to those inputs that provide or have the ability to provide a return (revenues, cost savings, or other economic benefits) to investors.

The Screen Test (Concentration Test)

ASC 805 includes an optional "screen" test to simplify the determination of whether an acquired set of assets is not a business. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the acquired set is not a business, and the transaction is accounted for as an asset acquisition. For example, if a company acquires a single warehouse building and its land, and the fair value of the building and land constitutes 98% of the total transaction value, it fails to meet the definition of a business.

The Acquisition Method

Every business combination must be accounted for using the Acquisition Method. This method requires:

  1. Identifying the Acquirer: The entity that obtains control of the acquiree.
  2. Determining the Acquisition Date: The date on which the acquirer obtains control (typically the closing date).
  3. Recognizing and Measuring Assets and Liabilities: Recognizing the identifiable assets acquired, liabilities assumed, and any noncontrolling interest (NCI) in the acquiree at their acquisition-date fair values.
  4. Recognizing Goodwill or a Bargain Purchase Gain: Goodwill is measured as the excess of the consideration transferred (plus the fair value of any NCI and any previously held equity interest) over the fair value of the net identifiable assets acquired.

Valuation Exceptions

While fair value is the general measurement principle under ASC 805, there are specific exceptions:

  • Income Taxes (ASC 740): Deferred tax assets and liabilities are measured in accordance with ASC 740, not at fair value.
  • Employee Benefits (ASC 715): Pension and other post-retirement benefit obligations are measured in accordance with employee benefit standards.
  • Indemnification Assets: Measured on the same basis as the indemnified item.

Transaction-Related and Acquisition Costs

Accounting for transaction costs is a frequent source of error. Note that under the CPA Evolution model effective 2024, business combinations and consolidations (ASC 805/810) are assessed primarily on the BAR Discipline section rather than the FAR Core section; FAR candidates planning to sit for BAR should master this material, while others can treat it as foundational background. Under ASC 805, all acquisition-related costs must be expensed in the periods in which they are incurred. They cannot be capitalized as part of the investment or goodwill.

  • Out-of-Pocket Costs: Legal fees, accounting fees, advisory fees, valuation fees, and consulting fees are expensed as incurred (debited to Acquisition Expense / M&A Expense).
  • Internal Costs: Internal M&A department salaries, travel, and administrative overhead are expensed as incurred.
  • Equity Issuance Costs: Costs incurred to register and issue equity securities (e.g., underwriting fees, SEC registration fees, legal fees for stock issuance) are treated as a reduction of the fair value of the equity issued. These are debited directly to Additional Paid-in Capital (APIC).
  • Debt Issuance Costs: Costs incurred to issue debt (e.g., underwriting fees, debt registration costs) are capitalized as a deferred charge (presented as a direct reduction of the debt liability) and amortized over the term of the debt using the effective interest method under ASC 835.

   Cr. Cash                                              $70,000

Contingent Consideration

Contingent consideration is an obligation of the acquirer to transfer additional assets or equity interests to the former owners of the acquiree if specified future events occur or conditions are met (e.g., hitting a sales target or obtaining FDA approval for a drug).

  • Initial Recognition: Measured at its acquisition-date fair value and included as part of the total consideration transferred.
  • Classification:
    • Liability-Classified: If the contract requires the acquirer to deliver cash, other assets, or a variable number of shares, it is classified as a liability.
    • Equity-Classified: If the contract requires the acquirer to deliver a fixed number of its own shares, it is classified as equity.
  • Subsequent Measurement:
    • Liability-Classified: Must be remeasured to fair value at each reporting date until settled, with changes in fair value recognized immediately in earnings (Gain or Loss on Contingent Consideration).
    • Equity-Classified: Is not remeasured. Subsequent settlement is accounted for entirely within equity (no impact on earnings).
Example subsequent remeasurement (Liability):
Dr. Loss on Contingent Consideration (Income Statement)   $30,000
   Cr. Contingent Consideration Liability                          $30,000

Bargain Purchase Gains

A bargain purchase occurs when the fair value of the net identifiable assets acquired exceeds the sum of the consideration transferred, the fair value of any NCI, and the fair value of any previously held equity interest.

  • Process: The acquirer must first reassess whether it has correctly identified all assets acquired and liabilities assumed. If the excess remains, the acquirer recognizes a Gain on Bargain Purchase in earnings on the acquisition date.
  • Journal Entry:
Dr. Cash                                      $100,000
Dr. Equipment (FV)                            $900,000
   Cr. Liabilities Assumed (FV)                         $200,000
   Cr. Cash (Consideration Transferred)                 $700,000
   Cr. Gain on Bargain Purchase (Earnings)              $100,000

The Measurement Period

Under ASC 805, an acquirer may not have all the necessary information to determine the fair value of assets, liabilities, or NCI on the acquisition date. In such cases, the acquirer reports provisional amounts. The acquirer has a period of up to one year from the acquisition date (the measurement period) to obtain the information needed to complete the accounting.

Key rules for measurement period adjustments:

  • Adjustments to provisional amounts are recognized retrospectively to the acquisition date.
  • Comparative prior-period financial statements are revised as if the adjustments had been recognized on the acquisition date.
  • Any change in provisional amounts impacts goodwill or the bargain purchase gain.
  • Once the measurement period ends (or when the acquirer receives the information, whichever is earlier), any subsequent changes are treated as corrections of errors under ASC 250, rather than measurement period adjustments, unless they relate to changes in contingent consideration (which follow the remeasurement rules).
