Determination of pro rata share
(d) Determination of pro rata share(1) In general. For purposes of paragraph (c) of this section, each United States shareholder that owns section 958(a) stock of a controlled foreign corporation as of a hypothetical distribution date determines its pro rata share (if any) of each tested item of the controlled foreign corporation for the CFC inclusion year that includes the hypothetical distribution date and ends with or within the U.S. shareholder inclusion year. Except as otherwise provided in this paragraph (d), a United States shareholder's pro rata share of each tested item is determined independently of its pro rata share of each other tested item. In no case may the sum of the pro rata share of any tested item of a controlled foreign corporation for a CFC inclusion year allocated to stock under this paragraph (d) exceed the amount of such tested item of the controlled foreign corporation for the CFC inclusion year. Except as modified in this paragraph (d), a United States shareholder's pro rata share of any tested item is determined under the rules of section 951(a)(2) and 1.951-1(b) and (e) in the same manner as those provisions apply to subpart F income. Under section 951(a)(2) and 1.951-1(b) and (e), as modified by this paragraph (d), a United States shareholder's pro rata share of any tested item for a U.S. shareholder inclusion year is determined with respect to the section 958(a) stock of the controlled foreign corporation owned by the United States shareholder on a hypothetical distribution date with respect to a CFC inclusion year that ends with or within the U.S. shareholder inclusion year. A United States shareholder's pro rata share of any tested item is translated into United States dollars using the average exchange rate for the CFC inclusion year of the controlled foreign corporation. Paragraphs (d)(2) through (5) of this section provide rules for determining a United States shareholder's pro rata share of each tested item of a controlled foreign corporation. (2) Tested income(i) In general. Except as provided in paragraph (d)(2)(ii) of this section, a United States shareholder's pro rata share of the tested income of each tested income CFC for a U.S. shareholder inclusion year is determined under section 951(a)(2) and 1.951-1(b) and (e), substituting tested income for subpart F income each place it appears, other than in 1.951-1(e)(1)(ii)(B) and the denominator of the fraction described in 1.951-1(b)(1)(ii)(A). (ii) Special rule for prior allocation of tested loss. In any case in which tested loss has been allocated to any class of stock in a prior CFC inclusion year under paragraph (d)(4)(iii) of this section, tested income is first allocated to each such class of stock in the order of its liquidation priority to the extent of the excess (if any) of the sum of the tested loss allocated to each such class of stock for each prior CFC inclusion year under paragraph (d)(4)(iii) of this section, over the sum of the tested income allocated to each such class of stock for each prior CFC inclusion year under this paragraph (d)(2)(ii). Paragraph (d)(2)(i) of this section applies for purposes of determining a United States shareholder's pro rata share of the remainder of the tested income, except that, for purposes of the hypothetical distribution of section 951(a)(2)(A) and 1.951-1(b)(1)(i) and (e)(1)(i), the amount of allocable earnings and profits of the tested income CFC is reduced by the amount of tested income allocated under the first sentence of this paragraph (d)(2)(ii). For an example of the application of this paragraph (d)(2), see paragraph (d)(4)(iv)(B) of this section (Example 2). (3) Qualified business asset investment(i) In general. Except as provided in paragraphs (d)(3)(ii) of this section, a United States shareholder's pro rata share of the qualified business asset investment of a tested income CFC for a U.S. shareholder inclusion year bears the same ratio to the total qualified business asset investment of the tested income CFC for the CFC inclusion year as the United States shareholder's pro rata share of the tested income of the tested income CFC for the U.S. shareholder inclusion year bears to the total tested income of the tested income CFC for the CFC inclusion year. (ii) Special rule for excess hypothetical tangible return(A) In general. If the tested income of a tested income CFC for a CFC inclusion year is less than the hypothetical tangible return of the tested income CFC for the CFC inclusion year, a United States shareholder's pro rata share of the qualified business asset investment of the tested income CFC for a United States shareholder inclusion year bears the same ratio to the qualified business asset investment of the tested income CFC as the United States shareholder's pro rata share of the hypothetical tangible return of the CFC for the U.S. shareholder inclusion year bears to the total hypothetical tangible return of the CFC for the CFC inclusion year. (B) Determination of pro rata share of hypothetical tangible return. For purposes of paragraph (d)(3)(ii)(A) of this section, a United States shareholder's pro rata share of the hypothetical tangible return of a CFC for a CFC inclusion year is determined in the same manner as the United States shareholder's pro rata share of the tested income of the CFC for the CFC inclusion year under paragraph (d)(2) of this section by treating the amount of the hypothetical tangible return as the amount of tested income. (C) Definition of hypothetical tangible return. For purposes of this paragraph (d)(3)(ii), the term hypothetical tangible return means, with respect to a tested income CFC for a CFC inclusion year, 10 percent of the qualified business asset investment of the tested income CFC for the CFC inclusion year. (iii) Examples. The following examples illustrate the application of paragraphs (d)(2) and (3) of this section. See also 1.951-1(e)(7)(vii) (Example 6) (illustrating a United States shareholder's pro rata share of tested income). (A) Example 1(1) Facts. FS, a controlled foreign corporation, has outstanding 70 shares of common stock and 30 shares of 4% nonparticipating, cumulative preferred stock with a par value of $10x per share. P Corp, a domestic corporation and a United States shareholder of FS, owns all of the common shares. Individual A, a United States citizen and a United States shareholder, owns all of the preferred shares. Individual A, FS, and P Corp use the calendar year as their taxable year. Individual A and P Corp are shareholders of FS for all of Year 4. At the beginning of Year 4, FS had no dividend arrearages with respect to its preferred stock. For Year 4, FS has $100x of earnings and profits, $120x of tested income, and no subpart F income within the meaning of section 952. FS also has $750x of qualified business asset investment for Year 4.
