Accounting Resources for ASC 805 and IFRS 3

A business combination is a transaction or other event in which an acquirer obtains control of one or more businesses. Business combinations are accounted for in accordance U.S. GAAP under ASC Topic 805 Business Combinations (ASC 805) and under IFRS 3 Business Combinations (IFRS 3). Although the accounting for business combinations is not hard per se, it can be tricky as you weave your way through the myriad of guidance.

We’ve published this accounting topic page to help you learn more about the accounting for business combinations, including accounting issues and U.S. GAAP vs. IFRS differences. We also provide helpful links to our blog posts and eLearning courses on the topic, as well as external thought leadership published by Big 4 accounting firms. We hope you enjoy!

Accounting Issues

Issue #1: Business Combinations vs. Asset Acquisitions

The first issue relates to determining what exactly was purchased. Did the entity purchase a business or just a bunch of assets? This determination matters because the accounting is vastly different!

Needless to say, the accounting for an asset acquisition is far easier than accounting for a business combination. Therefore, many purchase agreements often stipulate the transaction is an asset purchase. But, don’t let the wording fool you! If what is being acquired meets the definition of a business, then ASC 805 is applicable, regardless of what those pesky lawyers and tax accountants say!

According to ASC 805, to be considered a business, the acquired set needs to have an input and at least one substantive process that together significantly contribute to the ability to create outputs. The guidance provides a framework to evaluate when an input and substantive process are present, as well as providing more stringent criteria for sets without outputs to be considered a business.

Issue #2: Identifying the Assets Acquired and Liabilities Assumed

The second issue relates to identifying all the assets acquired and liabilities assumed (“net assets”) in the business combination. It’s important to start with the assets and liabilities reported on the acquiree’s balance sheet, but don’t stop there! Intangible assets must also be included if they are separable or arise from contractual or legal rights.

Included in the intangible assets acquired are in-process research and development (IPR&D) projects and brands, even if the acquirer intends to “kill the brand” post-acquisition.

Issue #3: Valuing the Assets Acquired and Liabilities Assumed

Now that the net assets acquired have been identified, ASC 805 requires the acquirer to determine the fair value of the net assets in accordance with ASC 820 Fair Value Measurements. This is the third issue relating to the accounting for business combinations.

Most of us didn’t go to school to learn how to value intangible assets. How do you measure the fair value of an IPR&D project in the “monkey phase” of trails? Or the fair value of a brand that the acquirer intends to “kill” post-acquisition? Who knows? However, what we do know is that market participant assumptions must be considered and, when you don’t know how to do something, ask for help! That’s why both preparers and auditors often rely on the work of specialists for such matters.

Issue #4: Accounting for Contingent Consideration

Any contingent consideration included in the business combination’s purchase agreement should be included in the purchase price. The amount to be included is measured at fair value at the date of the acquisition, not the expected payout at settlement. The probability of payment should be considered when determining fair value, not whether to record contingent consideration or not. In addition, the fair value should include the time value of money and, like all fair value measurements in accordance with ASC 820, based on market participant assumptions.

The acquirer must remeasure the contingent consideration each reporting period. And, since this remeasurement is recorded through current period earnings, this can lead to an incentive for management to overestimate contingent consideration at the acquisition date. Auditors should be careful in this area!

Issue #5: Determining the Measurement Period

The final accounting issue relates to an area where a lot of people misinterpret the guidance. Many companies believe they have up to one year to finalize the purchase price allocation, with any adjustments being recorded by an adjustment to goodwill. This is not true! The FASB didn’t give entities a one-year “blank check” to get the accounting straight. First, entities have to document and disclose within the financial statements which items are accounted for provisionally at the acquisition date. Second, the measurement period is not always one year. Once you have the information needed to determine the fair value of an asset or liability initially recorded provisionally, the measurement period ends.

Accounting Differences: ASC 805 vs. IFRS 3

The guidance within ASC 805 and IFRS 3 is largely converged. However, there are still differences in the accounting for business combinations under U.S. GAAP as compared to IFRS.

Although this is not an all-inclusive list, here are the top differences between U.S. GAAP and IFRS in the area of business combinations:

Accounting for Pre-acquisition Contingencies

Under ASC 805, all contingencies, including contingent assets, are recognized at fair value at the acquisition date, if fair value can be reasonably determined during the measurement period. If fair value cannot be reasonably determined, then such contingencies are measured using existing guidance. In other words, contingent liabilities that are probable would be measured at the best estimate of expected payment, while contingent assets would not be recorded.

Under IFRS 3, contingent liabilities, as defined in IAS 37, should be measured at fair value. However, entities are not permitted to recognize a contingent asset in a business combination.

Measurement of Noncontrolling Interest

Noncontrolling interest is the portion of equity (ownership interest) in a subsidiary not attributable directly or indirectly to the parent.

Under ASC 805, noncontrolling interest is measured at fair value.

Under IFRS 3, noncontrolling interests that are present ownership interests and entitle their holders to a proportionate share of the acquiree’s net assets in the event of liquidation may be measured at either:

This choice is available on a transaction-by-transaction basis. All other components of noncontrolling interest are measured at fair value unless another measurement basis is required by IFRS.

Measurement Period Adjustments

As noted above, the measurement period is the period during which adjustments can be made to amounts originally recorded at the acquisition date, with the corresponding entry to goodwill.

ASC 805 requires such adjustments to be made prospectively by adjusting amounts in the period in which the adjustment is determined.

IFRS 3 requires such adjustments to be made retrospectively by “recasting” prior periods.

Pushdown Accounting

Pushdown accounting refers to establishing a new basis of accounting in the separate financial statements of the acquired entity (or acquiree) after it is acquired by an acquirer. In other words, the cost of the acquisition is reflected in the separate financial statements of the acquired subsidiary, with the parent (acquirer) “pushing down” the fair values assigned to the assets and liabilities acquired, as well as goodwill.

ASC 805 gives entities the option to apply pushdown accounting and this election may be elected each time there is a change-in-control event in which an acquirer obtains control of the acquiree. If elected, pushdown accounting is irrevocable.

There is no equivalent guidance within IFRS 3 and, therefore, it is unclear whether pushdown accounting is acceptable under IFRS.

Combinations Involving Entities under Common Control

Combinations between entities or businesses under common control are outside the scope of ASC 805. A common example is when one subsidiary acquires another subsidiary, both of which are under the common control of the same parent entity. Generally, these transactions are recorded carrying forward the historical cost basis of the assets and liabilities of the parent.

IFRS 3 does not specifically address combinations between entities under common control. In practice, entities develop and consistently apply an accounting policy related to such transactions. In other words, they would either carry forward the historical cost basis of the parent, as required by U.S. GAAP, or apply acquisition accounting where the assets and liabilities acquired are recorded at fair value at the acquisition date.
