(i) A owns all the L stock. L owns 80 percent and B owns 20 percent of the L1 stock. For Year 1, the L group has a consolidated net operating loss that resulted from the operations of L1 and that is carried over to Year 2. The value of the L stock is $1000. The total value of the L1 stock is $600 and the value of the L1 stock held by B is $120. The L group is a loss group under § 1.1502-91(c)(1) because it is entitled to use its net operating loss carryover from Year 1. On August 15, Year 2, A sells 51 percent of the L stock to C. The following is a graphic illustration of these facts:

(ii) Under paragraph (b)(1)(i) of this section, section 382 and the regulations thereunder are applied to L to determine whether it (and therefore the L loss group) has an ownership change with respect to its net operating loss carryover from Year 1 attributable to L1 on August 15, Year 2. The sale of the L stock to C causes an ownership change of L under § 1.382-2T and of the L loss group under paragraph (b)(1)(i) of this section. The amount of consolidated taxable income of the L loss group for any post-change taxable year that may be offset by its pre-change consolidated attributes (that is, the net operating loss carryover from Year 1 attributable to L1) may not exceed the consolidated section 382 limitation for the L loss group for the taxable year.
(i) The facts are the same as in Example 1, except that on August 15, Year 2, A sells only 49 percent of the L stock to C and, on December 12, Year 3, in an unrelated transaction, B sells the 20 percent of the L1 stock to D. A's sale of the L stock to C does not cause an ownership change of L under § 1.382-2T nor of the L loss group under paragraph (b)(1)(i) of this section. The following is a graphic illustration of these facts:

(ii) B's subsequent sale of L1 stock is not taken into account for purposes of determining whether the L loss group has an ownership change under paragraph (b)(1)(i) of this section, and, accordingly, there is no ownership change of the L loss group. See paragraph (c) of this section, however, for a supplemental ownership change method that would apply to cause an ownership change if the purchases by C and D were pursuant to a plan or arrangement and certain other conditions are satisfied.
(i) P owns all the L stock. L owns 80 percent and A owns 20 percent of the L1 stock. The P group has a consolidated net operating loss arising in Year 1 that is carried over to Year 2. On September 9, Year 2, P sells 51 percent of the L stock to B, and L1 is apportioned a portion of the Year 1 consolidated net operating loss under § 1.1502-21(b), which it carries over to its next taxable year. L and L1 file a consolidated return for their first taxable year ending after the sale to B. The following is a graphic illustration of these facts:

(ii) Under § 1.1502-91(d)(1), L and L1 compose a loss subgroup on September 9, Year 2, the day that they become members of the L group. Under paragraph (b)(1)(ii) of this section, section 382 and the regulations thereunder are applied to L to determine whether it (and therefore the L loss subgroup) has an ownership change with respect to the portion of the Year 1 consolidated net operating loss that is apportioned to L1 on September 9, Year 2. L has an ownership change resulting from P's sale of 51 percent of the L stock to A. Therefore, the L loss subgroup has an ownership change with respect to that loss.
(i) A owns all the stock of corporation M, M owns 35 percent and B owns 65 percent of the L stock, and L owns all the L1 stock. The L group has a consolidated net operating loss arising in Year 1 that is carried over to Year 2. On May 19, Year 2, B sells 45 percent of the L stock to M for cash. M, L, and L1 thereafter file consolidated returns. L and L1 are each apportioned a portion of the Year 1 consolidated net operating loss, which they carry over to the M group's Year 2 and Year 3 consolidated return years. The M group has a consolidated net operating loss arising in Year 2 that is carried over to Year 3. On June 9, Year 3, A sells 70 percent of the M stock to C. The following is a graphic illustration of these facts:

(ii) Under § 1.1502-91(d)(1), L and L1 compose a loss subgroup on May 19, Year 2, the day they become members of the M group. Under paragraph (b)(1)(ii) of this section, section 382 and the regulations thereunder are applied to L to determine whether L (and therefore the L loss subgroup) has an ownership change with respect to the loss carryovers from Year 1 on May 19, Year 2, a testing date because of B's sale of L stock to M. The sale of L stock to M results in only a 45 percentage point increase in A's ownership of L stock. Thus, there is no ownership change of L (or the L loss subgroup) with respect to those loss carryovers under paragraph (b)(1)(ii) of this section on that day.
(iii) June 9, Year 3, is also a testing date with respect to the L loss subgroup because of A's sale of M stock to C. The sale results in a 56 percentage point increase in C's ownership of L stock, and L has an ownership change. Therefore, the L loss subgroup has an ownership change on that day with respect to the loss carryovers from Year 1.
(iv) Paragraph (b)(1)(i) of this section requires that section 382 and the regulations thereunder be applied to M to determine whether M (and therefore the M loss group) has an ownership change with respect to the net operating loss carryover from Year 2 on June 9, Year 3, a testing date because of A's sale of M stock to C. The sale results in a 70 percentage point increase in C's ownership of M stock, and M has an ownership change. Therefore, the M loss group has an ownership change on that day with respect to that loss carryover.
(i) P owns all the stock of L and L1 and 80 percent of the stock of T. A owns the remaining 20 percent of the stock of T. L1 owns all the stock of L2. P1, which owns 60 percent of the stock of P, acquires, at the beginning of Year 2, the T, L, and L1 stock owned by P, and T, L, L1, and L2 become members of the P1 group. The P group has a consolidated net operating loss arising in Year 1 that is carried over to Year 2. L, L1, and L2 are each apportioned a portion of the Year 1 consolidated net operating loss under § 1.1502-21(b), which they carry over to the P1 group's Year 2 and Year 3 consolidated return years. P1 makes the election described in § 1.1502-91(d)(4) to treat T, L, L1 and L2 as meeting the section 1504(a)(1) requirement of § 1.1502-91(d)(1)(ii). As a result of the election, T, L, L1 and L2 compose a loss subgroup and T, L, L1, and L2 are each treated as the loss subgroup parent for purposes of this paragraph (b). Because of P1's indirect ownership of T, L, L1, and L2 prior to P1's acquisition of the T, L, and L1 stock, P1's acquisition does not cause an ownership change of the loss subgroup.
(ii) On February 2, Year 3, L1 sells all of the stock of L2 to B. Although L2 is treated as a loss subgroup parent, the determination whether the loss subgroup comprised of T, L, and L1 has an ownership change under this paragraph (b) is made without regard to the sale of L2 because L2's ownership change occurred upon ceasing to be a member of the P1 group. See § 1.1502-95(b) to determine the application of section 382 to L2 when L2 ceases to be a member of the P1 group and the T, L, L1 and L2 loss subgroup.
(iii) On March 26, Year 3, A sells her 20 percent minority stock interest in T to C . C's purchase, together with the 32 percentage point owner shift effected by P1's acquisition of the T stock at the beginning of Year 2, causes an ownership change of T, and therefore of the loss subgroup comprised of T, L, and L1.



(i) A owns all the L stock. L is not a member of an affiliated group and has a net operating loss carryover arising in Year 1 that is carried over to Year 6. On September 20, Year 6, L transfers all of its assets and liabilities to a newly created subsidiary, S, in exchange for S stock. L and S thereafter file consolidated returns. On November 23, Year 6, B contributes cash to L in exchange for a 45 percent ownership interest in L and contributes cash to S for a 20 percent ownership interest in S.
(ii) During the 3 year period ending on November 23, Year 6, B is a 5% shareholder of L and of S that increases its ownership interest in L and S during that period. Under paragraph (c)(4)(ii) of this section, the determination whether L (the common parent of a loss group) has an ownership change on November 23, Year 6 (or, subject to paragraph (c)(4)(iv) of this section, on any testing date in the testing period which includes November 23, Year 6), is made by applying paragraph (b)(1)(i) of this section and by treating the value of B's 20 percent ownership interest in S as if it were L stock issued to B. Because B is a 5% shareholder of both L and S during the 3 year period ending on November 23, Year 6, and B's increase in its percentage ownership in the stock of S would be taken into account in determining if S (if it were a loss corporation) had an ownership change, it is not relevant whether L has actual knowledge of B's acquisition of S stock.
(i) A owns all the stock of L and L owns all the stock of L1. The L group has a consolidated net operating loss arising in Year 1 that resulted from the operations of L1 and that is carried over to Year 2. On October 7, Year 2, A sells 49 percent of the L stock to B. As part of a plan that includes the sale of L stock, A causes a public offering of L1 stock on November 6, Year 2. L has actual knowledge of the plan. The following is a graphic illustration of these facts:

(ii) A's sale of the L stock to B does not cause an ownership change of the L loss group on October 7, Year 2, under the rules of § 1.382-2T and paragraph (b)(1)(i) of this section.
(iii) Because the issuance of L1 stock to the public occurs as part of the same plan as B's acquisition of L stock, and L has knowledge of the plan, paragraph (c)(4) of this section applies to determine whether the L loss group has an ownership change on November 6, Year 2 (or, subject to paragraph (c)(4)(iv) of this section, on any testing date for which the testing period includes November 6, Year 2).
