§ 1.267(c)-1 — Constructive ownership of stock.

§ 1.267(c)-1 Constructive ownership of stock.

(a) In general. (1) The determination of stock ownership for purposes of section 267(b) shall be in accordance with the rules in section 267(c).

(2) For an individual to be considered under section 267(c)(2) as constructively owning the stock of a corporation which is owned, directly or indirectly, by or for members of his family it is not necessary that he own stock in the corporation either directly or indirectly. On the other hand, for an individual to be considered under section 267(c)(3) as owning the stock of a corporation owned either actually, or constructively under section 267(c)(1), by or for his partner, such individual must himself actually own, or constructively own under section 267(c)(1), stock of such corporation.

(3) An individual's constructive ownership, under section 267(c) (2) or (3), of stock owned directly or indirectly by or for a member of his family, or by or for his partner, is not to be considered as actual ownership of such stock, and the individual's constructive ownership of the stock is not to be attributed to another member of his family or to another partner. However, an individual's constructive ownership, under section 267(c)(1), of stock owned directly or indirectly by or for a corporation, partnership, estate, or trust shall be considered as actual ownership of the stock, and the individual's ownership may be attributed to a member of his family or to his partner.

(4) The family of an individual shall include only his brothers and sisters, spouse, ancestors, and lineal descendants. In determining whether any of these relationships exist, full effect shall be given to a legal adoption. The term ancestors includes parents and grandparents, and the term lineal descendants includes children and grandchildren.

(b) Examples. The application of section 267(c) may be illustrated by the following examples:

Example 1.On July 1, 1957, A owned 75 percent, and AW, his wife, owned 25 percent, of the outstanding stock of the M Corporation. The M Corporation in turn owned 80 percent of the outstanding stock of the O Corporation. Under section 267(c)(1), A and AW are each considered as owning an amount of the O Corporation stock actually owned by M Corporation in proportion to their respective ownership of M Corporation stock. Therefore, A constructively owns 60 percent (75 percent of 80 percent) of the O Corporation stock and AW constructively owns 20 percent (25 percent of 80 percent) of such stock. Under the family ownership rule of section 267(c)(2), an individual is considered as constructively owning the stock actually owned by his spouse. A and AW, therefore, are each considered as constructively owning the M Corporation stock actually owned by the other. For the purpose of applying this family ownership rule, A's and AW's constructive ownership of O Corporation stock is considered as actual ownership under section 267(c)(5). Thus, A constructively owns the 20 percent of the O Corporation stock constructively owned by AW, and AW constructively owns the 60 percent of the O Corporation stock constructively owned by A. In addition, the family ownership rule may be applied to make AWF, AW's father, the constructive owner of the 25 percent of the M Corporation stock actually owned by AW. As noted above, AW's constructive ownership of 20 percent of the O Corporation stock is considered as actual ownership for purposes of applying the family ownership rule, and AWF is thereby considered the constructive owner of this stock also. However, AW's constructive ownership of the stock constructively and actually owned by A may not be considered as actual ownership for the purpose of again applying the family ownership rule to make AWF the constructive owner of these shares. The ownership of the stock in the M and O Corporations may be tabulated as follows:

Person	Stock ownership in M Corporation		Total under Section 267 (Percent)	Stock ownsership in O Corporation		Total under Section 267 (Percent)
	Actual (Percent)	Constructive (Percent)		Actual (Percent)	Constructive (Percent)
A	75	25	100		60
				None		80
					20
A W (A's wife)	25	75	100		20
				None		80
					60
A W F (AW's father)	None	25	25	None	20	20
M Corporation				80	None	80
O Corporation	None	None	None

Assuming that the M Corporation and the O Corporation make their income tax returns for calendar years, and that there was no distribution in liquidation of the M or O Corporation, and further assuming that other corporation was a personal holding company under section 542 for the calendar year 1956, no deduction is allowable with respect to losses from sales or exchanges of property made on July 1, 1957, between the two corporations. Moreover, whether or not either corporation was a personal holding company, no loss would be allowable on a sale or exchange between A or AW and either corporation. A deduction would be allowed, however, for a loss sustained in an arm's length sale or exchange between A and AWF, and between AWF and the M or O Corporation.

Example 2.On June 15, 1957, all of the stock of the N Corporation was owned in equal proportions by A and his partner, AP. Except in the case of distributions in liquidation by the N Corporation, no deduction is allowable with respect to losses from sales or exchanges of property made on June 15, 1957, between A and the N Corporation or AP and the N Corporation since each partner is considered as owning the stock owned by the other; therefore, each is considered as owning more than 50 percent in value of the outstanding stock of the N Corporation. Example 3.On June 7, 1957, A owned no stock in X Corporation, but his wife, AW, owned 20 percent in value of the outstanding stock of X, and A's partner, AP, owned 60 percent in value of the outstanding stock of X. The partnership firm of A and AP owned no stock in X Corporation. The ownership of AW's stock is attributed to A, but not that of AP since A does not own any X Corporation stock either actually, or constructively under section 267(c)(1). A's constructive ownership of AW's stock is not the ownership required for the attribution of AP's stock. Therefore, deductions for losses from sales or exchanges of property made on June 7, 1957, between X Corporation and A or AW are allowable since neither person owned more than 50 percent in value of the outstanding stock of X, but deductions for losses from sales or exchanges between X Corporation and AP would not be allowable by section 267(a) (except for distributions in liquidation of X Corporation).
