(a) Constructive ownership—(1) In general. For purposes of section 4943, in computing the holdings in a business enterprise of a private foundation, or a disqualified person (as defined in section 4946), any stock or other interest owned, directly or indirectly, by or for a corporation, partnership, estate or trust shall be considered as being owned proportionately by or for its shareholders, partners, or beneficiaries except as otherwise provied paragraphs (b), (c) and (d) of this section. Any interest in a business enterprise actually or constructively owned by a shareholder of a corporation, a partner of a partnership, or beneficiary of an estate or trust shall not be considered as constructively held by the corporation, partnership, trust or estate. Further, if any corporation, partnership, estate or trust has a warrant or other option to acquire an interest in a business enterprise, such interest is not deemed to be constructively owned by such entity until the option is exercised. (See paragraph (b)(2) of §53.4943-3 for rules that options are not stock for purposes of determining excess business holdings.)

(2) Powers of appointment. Any interest in business enterprise over which a foundation or a disqualified person has a power of appointment exercisable in favor of the foundation or a disqualified person shall be considered owned by the foundation or disqualified person holding such power of appointment.

(3) Determination of extent of constructive ownership. If an interest in a business enterprise owned by a corporation is constructively owned by a shareholder, each shareholder's proportion of ownership is generally computed on the basis of the voting stock each shareholder has in the corporation. In determining holdings permitted under section 4943(c) (4) and (5), each shareholder's proportion of ownership in the business enterprise shall also be computed on the basis of value, taking into account both voting and nonvoting stock held by the shareholder.

(4) Nonvoting stock. If a private foundation, its disqualified persons, or both, own (directly or constructively) nonvoting stock of a parent corporation, the holdings of which are treated as constructively owned by its shareholders by reason of section 4943(d)(1) and this section, such nonvoting stock shall be treated as nonvoting stock of any corporation in which the parent corporation holds an interest for purposes of the limitation on the holding of nonvoting stock under section 4943(c)(2)(A) and §53.4943-3(b)(2).

(5) Interests held by certain disqualified persons. In the case of an entity that is a disqualified person (other than an entity described in section 4946(a)(1)(H)), the holdings of which are treated as constructively owned by its shareholders, partners, or beneficiaries, for purposes of determining the total holdings of disqualified persons the holdings of the entity shall be considered held by a disqualified person only to the extent such holdings are treated as constructively owned by disqualified persons who are shareholders, partners, or beneficiaries of the entity. In the case of an entity described in section 4946(a)(1)(H) or an entity, the holdings of which are not treated as constructively owned by its shareholders, partners, or beneficiaries, all holdings of such entity shall be treated as held by a disqualified person if and only if the entity itself is a disqualified person.

(b) Estates and trusts—(1) In general. Any interest actually or constructively owned by an estate or trust is deemed constructively owned, in the case of an estate, by its beneficiaries or, in the case of a trust, by its remainder beneficiaries except as provided in paragraphs (b) (2), (3) and (4) of this section (relating to certain split-interest trusts described in section 4947(a)(2), to trusts of qualified pension, profit-sharing, and stock bonus plans described in section 401(a) and to revocable trusts). Thus, if a trust owns 100 percent of the stock of a corporation A, and if, on an actuarial basis, W's life interest in the trust is 15 percent, Y's life interest is 25 percent, and Z's remainder interest is 60 percent, under this paragraph (b), Z will be considered to be the owner of 100 percent of the stock of corporation A. See §53.4943-4, §53.4943-5 and §53.4943-6 for rules relating to certain actual or constructive holdings of a foundation being treated as held by a disqualified person. For the treatment of certain property acquired by an estate or trust after May 26, 1969, see paragraph (a)(2) of §53.4943-5.

(2) Split-interest trusts—(i) Amounts transferred in trust after May 26, 1969. In the case of an interest in a business enterprise which was transferred to a trust described in section 4947(a)(2) after May 26, 1969, for the benefit of a private foundation, no portion of such interest shall be considered as owned by the private foundation:

(A) If the foundation holds only an income interest in the trust, or

(B) If the foundation holds only a remainder interest in the trust (unless the foundation can exercise primary investment discretion with respect to such interest)

until such trust ceases to be so described. See section 4947(a)(2) and (b)(3) and the regulations thereunder for rules relating to such trusts. See also sections 4946(a)(1) (G) and (H) and the regulations thereunder for rules relating to when a trust described in this paragraph (b)(2) is itself a disqualified person.

(ii) Amounts transferred in trust on or before May 26, 1969. In the case of an interest in a business enterprise which was transferred to a trust described in section 4947(a)(2) (without regard to section 4947(a)(2)(C)) on or before May 26, 1969, for the benefit of a private foundation, no portion of such interest shall be considered as owned by the foundation until it is actually distributed to the foundation or until the trust ceases to be so described. See section 4943(c)(5) and §53.4943-5 for rules relating to certain trusts which were irrevocable on May 26, 1969.

(3) Employee benefit trusts. An interest in a business enterprise owned by a trust described in section 401(a) (pension and profit-sharing plans) shall not be considered as owned by its beneficiaries, unless disqualified persons (within the meaning of section 4946) control the investment of the trust assets.

(4) Revocable trusts. An interest in a business enterprise owned by a revocable trust shall be treated as owned by the grantor of such trust.

(5) Estates. For purposes of applying section 4943(d)(1) to estates, the term “beneficiary” includes any person (including a private foundation) entitled to receive property of a decedent pursuant to a will or pursuant to laws of descent and distribution. However, a person shall no longer be considered a beneficiary of an estate when all the property to which he is entitled has been received by him, when he no longer has a claim against the estate and when there is only a remote possibility that it will be necessary for the estate to seek the return of property or to seek payment from him by contribution or otherwise to satisfy claims against the estate or expenses of administration. When pursuant to the preceding sentence, a person (including a private foundation) ceases to be a beneficiary, stock or another interest in a business enterprise owned by the estate shall not thereafter be considered owned by such person. If any person is the constructive owner of an interest in a business enterprise actually held by an estate, the date of death of the testator or decedent intestate shall be the first day on which such person shall be considered a constructive owner of such interest. See §53.4943-5 for rules relating to wills executed on or before May 26, 1969.

(c) Corporation actively engaged in a trade or business—(1) In general. Except as provided in paragraphs (c)(2) and (3) of this section, any interest (whether or not in a separate entity) owned by a corporation which is actively engaged in a trade or business shall not be deemed to be constructively owned by such corporation's shareholders.

(2) Actively engaged in a trade or business. For purposes of paragraph (c)(1) of this section:

(i) A corporation shall not be considerd to be actively engaged in a trade or business if the corporation is not a business enterprise by reason of section 4943(d)(3) (A) or (B) and §53.4943-10 (b) or (c);

(ii) In the case of a corporation which owns passive holdings and is actively engaged in a trade or business, such corporation shall not be considered to be actively engaged in a trade or business if the net assets used in such trade or business are insubstantial when compared to passive holdings.

(3) Exceptions. If a corporation has been involved in a prohibited transaction, any interest in a business enterprise owned by such corporation shall be treated as constructively owned by its shareholders, whether or not such corporation is actively engaged in a trade or business. For a definition of prohibited transaction, see §53.4943-7 (d)(2).

(4) Affiliated group. In applying this paragraph to the common parent in an affiliated group (as defined in §53.4943-10 (c)(3)(ii)), the assets and activities of the affiliated group shall be treated as the assets and activities of the common parent.

(d) Partnerships. Any interest in a business enterprise which is owned by a partnership shall be deemed to be constructively owned by the partners in such partnerships.

(e) Examples. The provisions of this section are illustrated by the following examples.
