(a) In general. Section 958(a) provides that, for purposes of sections 951 to 964 (other than sections 955(b)(1)(A) and (B) and 955(c)(2)(A)(ii) (as in effect before the enactment of the Tax Reduction Act of 1975), and 960(a)(1)), stock owned means—
(1) Stock owned directly; and
(2) Stock owned with the application of paragraph (b) of this section.
The rules of section 958(a) and this section provide a limited form of stock attribution primarily for use in determining the amount taxable to a United States shareholder under section 951(a). These rules also apply for purposes of other provisions of the Code and regulations which make express reference to section 958(a).
(b) Stock ownership through foreign entities. For purposes of paragraph (a)(2) of this section, stock owned, directly or indirectly, by or for a foreign corporation, foreign partnership, foreign trust (within the meaning of section 7701(a)(31)) described in sections 671 through 679, or other foreign trust or foreign estate (within the meaning of section 7701(a)(31)) shall be considered as being owned proportionately by its shareholders, partners, grantors or other persons treated as owners under sections 671 through 679 of any portion of the trust that includes the stock, or beneficiaries, respectively. Stock considered to be owned by reason of the application of this paragraph shall, for purposes of reapplying this paragraph, be treated as actually owned by such person. Thus, this rule creates a chain of ownership; however, since the rule applies only to stock owned by a foreign entity, attribution under the rule stops with the first United States person in the chain of ownership running from the foreign entity. The application of this paragraph may be illustrated by the following example:
(c) Rules of application—(1) Special rule for mutual insurance companies. For purposes of applying paragraph (a) of this section in the case of a foreign mutual insurance company, the term “stock” shall include any certificate entitling the holder to voting power in the corporation.
(2) Amount of interest in foreign corporation, foreign partnership, foreign trust, or foreign estate. The determination of a person's proportionate interest in a foreign corporation, foreign partnership, foreign trust, or foreign estate will be made on the basis of all the facts and circumstances in each case. Generally, in determining a person's proportionate interest in a foreign corporation, the purpose for which the rules of section 958(a) and this section are being applied will be taken into account. Thus, if the rules of section 958(a) are being applied to determine the amount of stock owned for purposes of section 951(a), a person's proportionate interest in a foreign corporation will generally be determined with reference to such person's interest in the income of such corporation. If the rules of section 958(a) are being applied to determine the amount of voting power owned for purposes of section 951(b) or 957, a person's proportionate interest in a foreign corporation will generally be determined with reference to the amount of voting power in such corporation owned by such person. However, any arrangement which artificially decreases a United States person's proportionate interest will not be recognized. See §§1.951-1 and 1.957-1.
