Paragraph (e) of this section provides definitions for purposes of this section. Paragraph (f) of this section provides examples illustrating the rules of this section. Paragraph (g) of this section provides an applicability date.
(b) Calculation of the GILTI inclusion amount for a member of a consolidated group.

(f) Examples. The following examples illustrate the rules of this section. For purposes of the examples in this section, unless otherwise stated: P is the common parent of the P consolidated group; P owns all of the single class of stock of subsidiaries USS1, USS2, and USS3, all of whom are members of the P consolidated group; CFC1, CFC2, CFC3, and CFC4 are all controlled foreign corporations (within the meaning of paragraph (e)(8) of this section); and the taxable year of all persons is the calendar year.
(1) Example 1: Calculation of net CFC tested income within a consolidated group when all CFCs are wholly owned by a member—
(i) Facts. USS1 owns all of the single class of stock of CFC1. USS2 owns all of the single class of stock of each of CFC2 and CFC3. USS3 owns all of the single class of stock of CFC4. In Year 1, CFC1 has tested loss of $100x, CFC2 has tested income of $200x, CFC3 has tested loss of $200x, and CFC4 has tested income of $600x. None of CFC1, CFC2, CFC3, or CFC4 has qualified business asset investment in Year 1.
(ii) Analysis—
(A) Consolidated tested income and GILTI allocation ratio. USS1 has no aggregate tested income; USS2's aggregate tested income is $200x, its pro rata share (determined under § 1.951A-1(d)(2)) of CFC2's tested income; and USS3's aggregate tested income is $600x, its pro rata share (determined under § 1.951A-1(d)(2)) of CFC4's tested income. Therefore, under paragraph (e)(6) of this section, the P consolidated group's consolidated tested income is $800x ($200x + $600x). As a result, the GILTI allocation ratios of USS1, USS2, and USS3 are 0 ($0/$800x), 0.25 ($200x/$800x), and 0.75 ($600x/$800x), respectively.
(B) Consolidated tested loss. Under paragraph (e)(7) of this section, the P consolidated group's consolidated tested loss is $300x ($100x + $200x), the sum of USS1's aggregate tested loss, which is equal to its pro rata share (determined under § 1.951A-1(d)(4)) of CFC1's tested loss ($100x), and USS2's aggregate tested loss, which is equal to its pro rata share (determined under § 1.951A-1(d)(4)) of CFC3's tested loss ($200x). Under paragraph (e)(3)(iii) of this section, a member's allocable share of the consolidated tested loss is the product of the consolidated tested loss of the member's consolidated group and the member's GILTI allocation ratio. Therefore, the allocable shares of the consolidated tested loss of USS1, USS2, and USS3 are $0 (0 × $300x), $75x (0.25 × $300x), and $225x (0.75 × $300x), respectively.
(C) Calculation of net CFC tested income. Under paragraph (e)(12) of this section, a member's net CFC tested income is the excess (if any) of the member's aggregate tested income over the member's allocable share of the consolidated tested loss. As a result, the net CFC tested income of USS1, USS2, and USS3 are $0 ($0−$0), $125x ($200x−$75x), and $375x ($600x−$225x), respectively.
(2) Example 2: Calculation of net CFC tested income within a consolidated group when ownership of a tested loss CFC is split between members—
(i) Facts. The facts are the same as in paragraph (f)(1)(i) of this section (the facts in Example 1), except that USS2 and USS3 each own 50% of the single class of stock of CFC3.
(ii) Analysis. As in paragraph (f)(1)(ii)(A) of this section (paragraph (A) of the analysis in Example 1), USS1 has no aggregate tested income and a GILTI allocation ratio of 0, USS2 has $200x of aggregate tested income and a GILTI allocation ratio of 0.25, and USS3 has $600x of aggregate tested income and a GILTI allocation ratio of 0.75. Additionally, the P consolidated group's consolidated tested loss is $300x (the aggregate of USS1's aggregate tested loss, which is equal to its pro rata share (determined under § 1.951A-1(d)(4)) of CFC1's tested loss ($100x); USS2's aggregate tested loss, which is equal to its pro rata share (determined under § 1.951A-1(d)(4)) of CFC3's tested loss ($100x); and USS3's aggregate tested loss, which is equal to its pro rata share (determined under § 1.951A-1(d)(4)) of CFC3's tested loss ($100x)). As a result, under paragraph (e)(12) of this section, as in paragraph (f)(1)(ii)(C) of this section (paragraph (C) of the analysis in Example 1), the net CFC tested income of USS1, USS2, and USS3 are $0 ($0−$0), $125x ($200x−$75x), and $375x ($600x−$225x), respectively.
(3) Example 3: Calculation of GILTI inclusion amount—
(i) Facts. The facts are the same as in paragraph (f)(1)(i) of this section (the facts in Example 1), except that CFC2 and CFC4 have qualified business asset investment of $500x and $2,000x, respectively, for Year 1. In Year 1, CFC1 and CFC4 each have tested interest expense (within the meaning of § 1.951A-4(b)(1)) of $25x, and none of CFC1, CFC2, CFC3, and CFC4 have tested interest income (within the meaning of § 1.951A-4(b)(2)). CFC1's tested loss of $100x and CFC4's tested income of $600x take into account the tested interest expense.
(ii) Analysis—
(A) GILTI allocation ratio. As in paragraph (f)(1)(ii)(A) of this section (paragraph (A) of the analysis in Example 1), the GILTI allocation ratios of USS1, USS2, and USS3 are 0 ($0/$800x), 0.25 ($200x/$800x), and 0.75 ($600x/$800x), respectively.
(B) Consolidated QBAI. Under paragraph (e)(4) of this section, the P consolidated group's consolidated QBAI is $2,500x ($500x + $2,000x), the aggregate of USS2's pro rata share (determined under § 1.951A-1(d)(3)) of the qualified business asset investment of CFC2 and USS3's pro rata share (determined under § 1.951A-1(d)(3)) of the qualified business asset investment of CFC4. Under paragraph (e)(3)(i) of this section, a member's allocable share of consolidated QBAI is the product of the consolidated QBAI of the member's consolidated group and the member's GILTI allocation ratio. Therefore, the allocable shares of the consolidated QBAI of each of USS1, USS2, and USS3 are $0 (0 × $2,500x), $625x (0.25 × $2,500x), and $1,875x (0.75 × $2,500x), respectively.
(C) Consolidated specified interest expense—
(1) Pro rata share of tested interest expense. USS1's pro rata share (determined under § 1.951A-1(d)(5)) of the tested interest expense of CFC1 is $25x, the amount by which the tested interest expense increases USS1's pro rata share of CFC1's tested loss (from $75x to $100x) for Year 1. USS3's pro rata share (determined under § 1.951A-1(d)(5)) of the tested interest expense of CFC4 is also $25x, the amount by which the tested interest expense decreases USS3's pro rata share of CFC4's tested income (from $625x to $600x).
(2) Consolidated specified interest expense. Under paragraph (e)(5) of this section, the P consolidated group's consolidated specified interest expense is $50x, the excess of the sum of each member's pro rata share of the tested interest expense of each controlled foreign corporation ($50x, $25x from USS1 + $25x from USS3), over the sum of each member's pro rata share of tested interest income ($0). Under paragraph (e)(3)(ii) of this section, a member's allocable share of consolidated specified interest expense is the product of the consolidated specified interest expense of the member's consolidated group and the member's GILTI allocation ratio. Therefore, the allocable shares of consolidated specified interest expense of USS1, USS2, and USS3 are $0 (0 × $50x), $12.50x (0.25 × $50x), and $37.50x (0.75 × $50x), respectively.
(D) Calculation of deemed tangible income return. Under paragraph (e)(9) of this section, a member's deemed tangible income return means 10 percent of the member's allocable share of the consolidated QBAI. As a result, the deemed tangible income returns of USS1, USS2, and USS3 are $0 (0.1 × $0), $62.50x (0.1 × $625x), and $187.50x (0.1 × $1,875x), respectively.
(E) Calculation of net deemed tangible income return. Under paragraph (e)(13) of this section, a member's net deemed tangible income return means the excess (if any) of a member's deemed tangible income return over the member's allocable share of the consolidated specified interest expense. As a result, the net deemed tangible income returns of USS1, USS2, and USS3 are $0 ($0−$0), $50x ($62.50x−$12.50x), and $150x ($187.50x−$37.50x), respectively.
(F) Calculation of GILTI inclusion amount. Under paragraph (b) of this section, a member's GILTI inclusion amount for a U.S. shareholder inclusion year is the excess (if any) of the member's net CFC tested income for the U.S. shareholder inclusion year, over the shareholder's net deemed tangible income return for the U.S. shareholder inclusion year. As described in paragraph (f)(1)(ii)(C) of this section (paragraph (C) of the analysis in Example 1), the net CFC tested income of USS1, USS2, and USS3 are $0, $125x, and $375x, respectively. As described in paragraph (f)(3)(ii)(E) of this section (paragraph (E) of the analysis in this example), the net deemed tangible income returns of USS1, USS2, and USS3 are $0, $50x, and $150x, respectively. As a result, under paragraph (b) of this section, the GILTI inclusion amounts of USS1, USS2, and USS3 are $0 ($0−$0), $75x ($125x−$50x), and $225x ($375x−$150x), respectively.
(g) Applicability date—
(1) In general. Except as otherwise provided in this paragraph (g), this section applies to taxable years of United States shareholders for which the due date (without extensions) of the consolidated return is after June 21, 2019. However, a consolidated group may apply the rules of this section in their entirety to all taxable years of its members that are described in § 1.951A-7(a). In such a case, the consolidated group must apply the rules of this section to all taxable years described in § 1.951A-7(a) and with respect to all members.
