(a) End of separate tracking of losses—(1) Application. This paragraph (a) applies to a member (or a loss subgroup) with a net operating loss carryover that arose (or is treated under § 1.1502-21(c) or 1.1502-21T(c) in effect prior to June 25, 1999, as contained in 26 CFR part 1 revised April 1, 1999, as applicable as arising) in a SRLY (or a net unrealized built-in gain or loss determined at the time that the member (or loss subgroup) becomes a member of the consolidated group if there is—

(i) An ownership change of the member (or loss subgroup in connection with, or after, becoming a member of the group; or

(ii) A period of 5 consecutive years following the day that the member (or loss subgroup) becomes a member of a group during which the member (or loss subgroup) has not had an ownership change.

(2) Effect of end of separate tracking. If this paragraph (a) applies with respect to a member (or loss subgroup), then, starting on the day after the earlier of the change date (but not earlier than the day the member (or loss subgroup) becomes a member of the consolidated group) or the last day of the 5 consecutive year period described in paragraph (a)(1)(ii) of this section, the member's net operating loss carryover that arose (or is treated under § 1.1502-21(c) or 1.1502-21T(c) in effect prior to June 25, 1999, as contained in 26 CFR part 1 revised April 1, 1999, as applicable as arising) in a SRLY, is treated as described in § 1.1502-91A(c)(1)(i). Also, the member's separately computed net unrealized built-in gain or loss is included in the determination whether the group has a net unrealized built-in gain or loss. The preceding sentences also apply for purposes of determining whether there is an ownership change with respect to such attributes following such change date (or earlier day) or 5 consecutive year period. Thus, for example, starting the day after the change date or the end of the 5 consecutive year period—

(i) The consolidated group which includes the new loss member or loss subgroup is no longer required to separately track owner shifts of the stock of the new loss member or loss subgroup parent to determine if an ownership change occurs with respect to the attributes of the new loss member or members included in the loss subgroup;

(ii) The group includes the member's attributes in determining whether it is a loss group under § 1.1502-91A(c);

(iii) There is an ownership change with respect to such attributes only if the group is a loss group and has an ownership change; and

(iv) If the group has an ownership change, such attributes are pre-change consolidated attributes subject to the loss group's consolidated section 382 limitation.

(3) Continuing effect of end of separate tracking. As the context may require, a current group determines which of its members are included in a loss subgroup on any testing date by taking into account the application of this section in the former group. See the example in § 1.1502-91A(f)(2).

(4) Special rule for testing period. For purposes of determining the beginning of the testing period for a loss group, the member's (or loss subgroup's) net operating loss carryovers (or net unrealized built-in gain or loss) described in paragraph (a)(2) of this section are considered to arise—

(i) In a case described in paragraph (a)(1)(i) of this section, in a taxable year that begins not earlier than the later of the day following the change date or the day that the member becomes a member of the group; and

(ii) in a case described in paragraph (a)(1)(ii) of this section, in a taxable year that begins 3 years before the end of the 5 consecutive year period.

(5) Limits on effects of end of separate tracking. The rule contained in this paragraph (a) applies solely for purposes of §§ 1.1502-91A through 1.1502-95A and this section (other than paragraph (b)(2)(ii)(B) of this section (relating to the definition of pre-change attributes of a subsidiary)) and § 1.1502-98A, and not for purposes of other provisions of the consolidated return regulations, including, for example, §§ 1.1502-15 and 1.1502-21 (or § 1.1502-15T in effect prior to June 25, 1999, as contained in 26 CFR part 1 revised April 1, 1999, and 1.1502-21T in effect prior to June 25, 1999, as contained in 26 CFR part 1 revised April 1, 1999, as applicable) (relating to the consolidated net operating loss deduction). See also paragraph (c) of this section for the continuing effect of an ownership change with respect to pre-change attributes.

(b) Ownership change of subsidiary—(1) Ownership change of a subsidiary because of options or plan or arrangement. Notwithstanding § 1.1502-92A, a subsidiary may have an ownership change for purposes of section 382 with respect to its attributes which a group or loss subgroup includes in making a determination under § 1.1502-91A(c)(1) (relating to the definition of loss group) or § 1.1502-91A(d) (relating to the definition of loss subgroup). The subsidiary has such an ownership change if it has an ownership change under the principles of § 1.1502-95A(b) and section 382 and the regulations thereunder (determined on a separate entity basis by treating the subsidiary as not being a member of a consolidated group) in the event of—

(i) The deemed exercise under § 1.382-4(d) of an option or options (other than an option with respect to stock of the common parent) held by a person (or persons acting pursuant to a plan or arrangement) to acquire more than 20 percent of the stock of the subsidiary; or

(ii) An increase by 1 or more 5-percent shareholders, acting pursuant to a plan or arrangement to avoid an ownership change of a subsidiary, in their percentage ownership interest in the subsidiary by more than 50 percentage points during the testing period of the subsidiary through the acquisition (or deemed acquisition pursuant to § 1.382-4(d)) of ownership interests in the subsidiary and in higher-tier members with respect to the subsidiary.

(2) Effect of the ownership change—(i) In general. If a subsidiary has an ownership change under paragraph (b)(1) of this section, the amount of consolidated taxable income for any post-change year that may be offset by the pre-change losses of the subsidiary shall not exceed the section 382 limitation for the subsidiary. For purposes of this limitation, the value of the subsidiary is determined solely by reference to the value of the subsidiary's stock.

(ii) Pre-change losses. The pre-change losses of a subsidiary are—

(A) Its allocable part of any consolidated net operating loss which is attributable to it under § 1.1502-21(b) or 1.1502-21T(b) in effect prior to June 25, 1999, as contained in 26 CFR part 1 revised April 1, 1999, as applicable (determined on the last day of the consolidated return year that includes the change date) that is not carried back and absorbed in a taxable year prior to the year including the change date;

(B) Its net operating loss carryovers that arose (or are treated under § 1.1502-21(c) or 1.1502-21T(c) in effect prior to June 25, 1999, as contained in 26 CFR part 1 revised April 1, 1999, as applicable as having arisen) in a SRLY; and

(C) Its recognized built-in loss with respect to its separately computed net unrealized built-in loss, if any, determined on the change date.

(3) Coordination with §§ 1.1502-91A, 1.1502-92A, and 1.1502-94A. If an increase in percentage ownership interest causes an ownership change with respect to an attribute under this paragraph (b) and under § 1.1502-92A on the same day, the ownership change is considered to occur only under § 1.1502-92A and not under this paragraph (b). See § 1.1502-94A for anti-duplication rules relating to value.

(4) Example. The following example illustrates paragraph (b)(1)(ii) of this section.

Example. Plan to avoid an ownership change of a subsidiary.(a) L owns all the stock of L1, L1 owns all the stock of L2, L2 owns all the stock of L3, and L3 owns all the stock of L4. The L group has a consolidated net operating loss arising in Year 1 that is carried over to Year 2. L has assets other than its L1 stock with a value of $900. L1, L2, and L3 own no assets other than their L2, L3, and L4 stock. L4 has assets with a value of $100. During Year 2, A, B, C, and D, acting pursuant to a plan to avoid an ownership change of L4, acquire the following ownership interests in the members of the L loss group: (A) on September 11, Year 2, A acquires 20 percent of the L1 stock from L and B acquires 20 percent of the L2 stock from L1; and (B) on September 20, Year 2, C acquires 20 percent of the stock of L3 from L2 and D acquires 20 percent of the stock of L4 from L3. The following is a graphic illustration of these facts: (b) The acquisitions by A, B, C, and D pursuant to the plan have increased their respective percentage ownership interests in L4 by approximately 10, 13, 16, and 20 percentage points, for a total of approximately 59 percentage points during the testing period. This more than 50 percentage point increase in the percentage ownership interest in L4 causes an ownership change of L4 under paragraph (b)(2) of this section.

(c) Continuing effect of an ownership change. A loss corporation (or loss subgroup) that is subject to a limitation under section 382 with respect to its pre-change losses continues to be subject to the limitation regardless of whether it becomes a member or ceases to be a member of a consolidated group. See § 1.382-5(d) (relating to successive ownership changes and absorption of a section 382 limitation).
