Rule of Law:
A transaction that qualifies as a statutory merger under state law does not automatically qualify as a tax-free 'reorganization' under federal tax law unless it also satisfies the judicially-created 'continuity of interest' doctrine, which requires that the shareholders of the acquired corporation retain a substantial proprietary stake in the acquiring corporation.
Facts:
- Southwest Natural Gas Company (Southwest) and Peoples Gas & Fuel Corporation (Peoples) entered into a merger agreement under Delaware state law.
- Under the agreement, all of Peoples' assets were transferred to Southwest.
- In exchange for their shares, Peoples' stockholders were offered a combination of cash, bonds, and common stock in Southwest.
- Shareholders holding 7,690 of Peoples' 18,875 shares (approximately 41%) accepted an option to receive only cash for their shares.
- The remaining shareholders of Peoples (holding approximately 59% of the shares) received a package of Southwest's common stock, mortgage bonds, and cash.
- The market value of the Southwest common stock received by these remaining shareholders constituted less than one percent of the total consideration they received in the exchange.
Procedural Posture:
- The Commissioner of Internal Revenue assessed tax deficiencies against Southwest Natural Gas Company for the years 1941 and 1942.
- Southwest Natural Gas Company petitioned the Tax Court of the United States for a redetermination of the deficiencies.
- The Tax Court upheld the Commissioner's determination, ruling that the merger transaction constituted a sale rather than a tax-free reorganization.
- Southwest Natural Gas Company, as petitioner, appealed the Tax Court's decision to the United States Court of Appeals for the Fifth Circuit.

Issue:
Does a statutory merger qualify as a tax-free 'reorganization' under Section 112(g) of the Internal Revenue Code if the shareholders of the acquired corporation receive consideration of which less than 1% of the value is in the form of an equity interest in the surviving corporation?
Opinions:
Majority - Russell, Circuit Judge.
No. A statutory merger does not qualify as a tax-free reorganization if the shareholders of the transferor corporation fail to retain a substantial proprietary interest in the transferee corporation. Merely literal compliance with a state merger statute is insufficient; the transaction must also satisfy the 'continuity of interest' test, which serves the underlying purpose of the tax code's reorganization provisions. This test requires that the shareholders of the acquired corporation retain a substantial proprietary stake in the ongoing enterprise, and that this retained interest represents a substantial part of the value of the property transferred. In this case, the proprietary interest (stock) retained by the former Peoples shareholders had a market value of less than one percent of the total consideration they received. This is not a substantial stake, and therefore the continuity of interest test is not met, rendering the transaction a taxable sale rather than a tax-free reorganization.
Dissenting - Joseph C. Hutcheson, Jr., Chief Judge
Yes. The majority and Tax Court incorrectly determined this was a sale by focusing too narrowly on the low market value of the stock received, rather than on the substance and control dynamics of the transaction. The dissent argues that the key fact is that the former Peoples shareholders received common stock—an equity interest representing voting power and a stake in the company's future growth, which is fundamentally different from bonds or cash. Furthermore, there was significant pre-existing ownership overlap, and the same group of individuals who controlled both corporations before the merger remained in control of the surviving entity. These factors demonstrate a genuine continuity of the business enterprise under modified corporate form, which is the exact scenario the reorganization provisions were designed to cover, making the transaction a reorganization, not a sale.
Analysis:
This case solidifies the principle that substance prevails over form in the context of corporate reorganizations for tax purposes. It affirms that the judicially-created 'continuity of interest' doctrine is an independent requirement that must be met in addition to the literal statutory requirements for a merger. The court's focus on the value of the proprietary interest received, rather than just its form, provides a quantitative element to the 'substantiality' test. This decision makes it more difficult for corporations to structure transactions as tax-free reorganizations when they are, in economic reality, cash sales with a de minimis equity component included merely to satisfy the statute's literal language.
