The Continuity of Business Enterprise requirement, known as COBE, is a Treasury regulation that a corporate merger or acquisition must satisfy to qualify as a tax-free reorganization under Section 368 of the Internal Revenue Code. After the deal closes, the acquiring corporation must either keep running the target’s historic business or keep using a significant portion of the target’s historic business assets in a business. If neither happens, the transaction loses its tax-deferred status and is treated as a taxable sale or liquidation, with immediate gain recognition for the corporations and their shareholders.
The rule lives in Treasury Regulation ยง 1.368-1(d). Its stated purpose is to limit tax-free reorganization treatment to “readjustments of continuing interests in property under modified corporate form,” rather than disguised sales or liquidations dressed up in reorganization paperwork.1eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges COBE is distinct from Continuity of Proprietary Interest, which looks at whether the target’s shareholders retain an ongoing equity stake. COBE looks at the enterprise itself: what happens to the business and the assets.
The Two Ways to Satisfy COBE
You only need to pass one of the two tests. The acquiring corporation (called “P” in the regulations) can either continue the historic business of the target (“T”), or use a significant portion of T’s historic business assets in a business.1eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges
Continuing the Historic Business
The target’s historic business is the business it has most recently conducted. A business the target entered into as part of the reorganization plan does not count. A company cannot pivot to a new line of work on the eve of the merger and label that new activity as its historic business.
When the target ran a single business, the acquirer must keep running it. When the target had multiple lines of business, the acquirer only needs to continue a significant line. The regulations set no numerical threshold. All facts and circumstances control, so a line that is small by revenue can still be significant if it carries critical intellectual property, specialized capabilities, or key customer relationships.
Being in the same industry as the target is not, by itself, enough. The regulations say that operating in the same line of business “tends to establish” continuity but “is not alone sufficient.” The acquirer has to actually carry on the target’s operations.
A regulatory example shows how forgiving this can be when the pieces are structured correctly: a target with three roughly equal lines of business (synthetic resin manufacturing, textile chemicals, and chemical distribution) sells two of them to a third party for cash before the merger. The acquirer continues the textile chemicals business without interruption. COBE is satisfied, even though two-thirds of the target’s operations were cashed out beforehand.2eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges
Using the Historic Business Assets
If the acquirer does not keep running the target’s business, it can still satisfy COBE by using a significant portion of the target’s historic business assets in any business. The new activity does not have to resemble what the target did.2eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges
Historic business assets are the assets actually used in the target’s historic business. They include tangible property such as plants and equipment and intangibles such as goodwill, patents, and trademarks, whether or not they carry a tax basis. Stock and securities can count when they were used in the target’s operations.
Whether a portion is “significant” turns primarily on the relative importance of the retained assets to the target’s business. Net fair market value matters, but it is not the only factor. Specialized machinery central to the target’s manufacturing process carries more weight than generic office furniture, even if the furniture had a higher book value.
The regulations illustrate how little actual operation is required: a target makes computer components and sells all of its output to the acquirer. After the merger, the acquirer switches to imported components and stops the target’s manufacturing, but keeps the target’s equipment on hand as a backup supply source. That use of the equipment satisfies the asset test, even though the acquirer never resumes the target’s business.2eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges
What Breaks COBE
Most COBE failures look the same. The target converts its operating assets to cash or an investment portfolio before closing, and the acquirer deploys those proceeds in its own business. The regulations treat cash and investment securities received in exchange for real business assets as not being historic business assets.
Two regulatory examples make the line clear. In one, a trouser manufacturer sells everything and buys a diversified stock and bond portfolio before merging into a regulated investment company. COBE fails: the investment activity is not the target’s historic business, and the portfolio is not historic business assets.2eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges In the other, a toy manufacturer sells all of its assets for cash and notes, then merges into a steel distributor. COBE fails again, because “the use of the sales proceeds in P’s business is not sufficient.”
The same result follows when the acquirer disposes of all of the target’s assets right after closing as part of the plan. A farm machinery manufacturer merges into a lumber mill operator that immediately dumps all the farm machinery assets. No continuing business, no continuing assets, no COBE.2eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges
Pre-Closing Asset Sales
A target can sell assets before the reorganization without automatically breaking COBE, as long as enough of the business or assets survive on one of the two tests. The three-line-of-business example above makes that point directly: two divisions cashed out, one continued, COBE satisfied.
The distinction that matters is between trimming peripheral assets while preserving the core and selling the entire business so that nothing but cash passes through the merger. Timing feeds into this. The regulations ask whether asset sales were part of the plan of reorganization or independent of it, and all facts and circumstances govern when the plan came into being. Dispositions done long before any merger discussions carry less risk than fire sales in the weeks before closing.
Holding Through Subsidiaries or Partnerships
The acquirer does not have to hold the assets directly or operate the business in-house. For COBE purposes, the acquirer is treated as owning all businesses and assets held by members of its “qualified group,” meaning any chain of corporations connected through stock ownership in which each link meets the 80-percent control threshold of Section 368(c).2eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges Pushing the target’s business or assets down to a subsidiary, or even to a sub-subsidiary, keeps COBE intact as long as every link holds 80 percent.
Partnerships work differently. The acquirer can be treated as conducting a partnership’s business if members of its qualified group either own a significant interest in the partnership or perform active and substantial management functions as a partner.2eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges “Significant interest” is not defined numerically, though the regulatory examples suggest a one-third interest qualifies and a one-percent interest does not. Even where the partnership test is met, operating a historic business through a partnership only “tends to establish” continuity and is “not alone sufficient.”
Which Reorganizations COBE Applies To
COBE applies to most of the reorganization types defined in Section 368(a)(1), including statutory mergers (Type A), stock-for-stock acquisitions (Type B), asset acquisitions (Type C), and transfers to a controlled corporation (Type D).3Office of the Law Revision Counsel. 26 U.S. Code 368 – Definitions Relating to Corporate Reorganizations Two types are exempt: recapitalizations (Type E) and mere changes in corporate form or identity (Type F) do not require COBE or Continuity of Proprietary Interest.1eCFR. 26 CFR 1.368-1 – Purpose and Scope of Exception of Reorganization Exchanges Those involve internal restructurings that do not raise the “is this really a sale?” concern that COBE exists to police.
What Happens If COBE Fails
A transaction that fails COBE cannot qualify as a reorganization under Section 368. The nonrecognition provisions that normally shield the corporations and shareholders drop away.
Section 361 ordinarily protects a corporation that is a party to a reorganization from recognizing gain or loss on property it exchanges under the plan.4Office of the Law Revision Counsel. 26 U.S. Code 361 – Nonrecognition of Gain or Loss to Corporations Without a qualifying reorganization, that protection is gone. The target recognizes gain or loss on the transfer of its assets, measured by the spread between fair market value and adjusted basis.
Shareholders normally rely on Section 354, which lets them exchange stock in one party for stock in another party to a reorganization without recognizing gain or loss.5Office of the Law Revision Counsel. 26 USC 354 – Exchanges of Stock and Securities in Certain Reorganizations When the reorganization fails, that section does not apply. Shareholders are instead treated as receiving a distribution in complete liquidation under Section 331, with the amounts received treated as payment in exchange for their stock, and any gain recognized immediately.6Office of the Law Revision Counsel. 26 U.S. Code 331 – Gain or Loss to Shareholder in Corporate Liquidations
Because COBE is evaluated based on what actually happens after closing, the risk is not always visible on the day the deal signs. An acquirer that intends to continue the target’s operations but changes course a year later can retroactively destroy the reorganization, converting a deferred-tax transaction into an immediate tax bill for every party.
