What it means
A corporate merger can be structured as a sale or as a qualifying reorganization, and the tax result depends on substance and statutory requirements, not the transaction's label. United States Treasury Regulation 1.368-1(d) describes continuity of business enterprise, often abbreviated COBE.
One route is business continuity, where the acquiring or issuing corporation continues the target's historic business. Another route is asset continuity, where a significant portion of the target's historic business assets is used in a business.
The rule focuses on the target's business or assets, so continuing only the buyer's old business does not by itself establish the target's continuity. If the target has several significant business lines, continuing one significant line can be enough under the cited regulation.
Historic business generally means the business recently conducted by the target, not a temporary activity added as part of a reorganization plan. Assets can include operating intangibles such as goodwill, trademarks and patents, even if they lack a tax basis.
Significant asset use is not always a fixed percentage, since relative importance to operations and other facts can matter. The regulation's examples include keeping acquired equipment as a backup source for production, which can count as business use in its specific facts.
Simply selling all target assets and using the cash in the buyer's business does not necessarily satisfy asset continuity. Related corporate groups and some partnership arrangements have special attribution rules, so a business need not always remain in the exact entity that signed the acquisition.
A qualifying reorganization also has requirements beyond COBE, including the relevant statutory type and often continuity of interest. Continuity of interest asks whether former target owners retain a continuing proprietary interest, and it should not be substituted for the operating-business test.
The regulation notes exceptions for certain E and F reorganizations, so avoid saying COBE is required in every transaction under section 368. A deal undertaken solely to disguise a sale can fail despite formal steps, and the regulation discusses a bona fide reorganization plan and business purpose.
A tax-deferred exchange may defer gain rather than erase it, and changes after closing can affect the factual assessment, so document intended operations and actual use of the target assets. A manager can ask which business line will continue, which assets will be used and which corporate group members will hold them, but this is a technical U.S. tax doctrine and transaction counsel must assess current law and the complete transaction before relying on favourable treatment.
In practice
Real-world examples.
Example
A buyer merges a three-line target and continues one significant historic business line after closing. The other two lines are closed or sold. Counsel records that the continued line was a core activity of the target and not a short-term addition.
Example
An acquirer puts a meaningful part of the target's equipment to use in an operating business instead of immediately selling it. The equipment keeps producing goods for the combined group. The deal file lists each major asset and where it is used after closing.
Example
A target shifts into a temporary investment activity just before a planned transaction; that activity is not automatically its historic business. Advisers look back to the business the target actually conducted for a meaningful period. The recent change adds risk rather than satisfying the test.
Formula
Calculation
There is no universal percentage formula for COBE. The regulatory test asks whether the issuing corporation continues the target's historic business OR uses a significant portion of historic business assets in a business, subject to facts and specific rules. A deal model can list each target business and asset, post-closing use and evidence. For a screening worksheet, suppose a target has three lines with revenue of $6 million, $3 million and $1 million; the largest line is $6 million / $10 million = 60% of revenue, which is a fact pointing towards significance, but a numerical share alone does not decide qualification.Case study
Seen in the real world.
Fictional case: A technology acquirer buys a target with a software platform and a small hardware line. Its deal team plans to sell the hardware inventory but continue the software service using staff and intellectual property. Tax counsel checks whether software was a significant historic business and reviews the transaction type, ownership consideration and group structure. The team documents actual post-closing activity.
They do not claim tax deferral solely because the seller's shareholders receive some stock, nor do they count the buyer's unrelated legacy business as continuation of the target. Counsel adds a closing checklist: confirm which team keeps running the software service, confirm the intellectual property is not sold on, and keep dated records of both. In this fictional example the checklist turns an abstract doctrine into three dated facts that can be shown to a tax authority if asked.
Watch out
Common mistakes.
- Confusing target-business continuity with the separate shareholder continuity-of-interest test.
- Assuming use of sale proceeds is equivalent to using the target's historic business assets.
- Calling every section 368 transaction subject to COBE despite identified exceptions.
Questions
People also ask.
Must every target business line continue?
No. The cited rule can be met by continuing a significant historic line, depending on facts.
Can intangible assets count?
Yes. Historic business assets can include operating intangibles such as goodwill and patents.
Does passing COBE guarantee tax-deferred status?
No. Other reorganization and transaction requirements must also be satisfied.
