Sec. 1.1502-21T  Net operating losses (temporary).

    (a) [Reserved]. For further guidance, see Sec. 1.1502-21(a).
    (b) [Reserved]. For further guidance, see Sec. 1.1502-21(b).
    (1) Carryovers and carrybacks generally. The net operating loss 
carryovers and carrybacks to a taxable year are determined under the 
principles of section 172 and this section. Thus, losses permitted to be 
absorbed in a consolidated return year generally are absorbed in the 
order of the taxable years in which they arose, and losses carried from 
taxable years ending on the same date, and which are available to offset 
consolidated taxable income for the year, generally are absorbed on a 
pro rata basis. In addition, the amount of any CNOL absorbed by the 
group in any year is apportioned among members based on the percentage 
of the CNOL attributable to each member as of the beginning of the year. 
The percentage of the CNOL attributable to a member is determined 
pursuant to paragraph (b)(2)(iv)(B) of this section. Additional rules 
provided under the Internal Revenue Code or regulations also apply. See, 
e.g., section

[[Page 361]]

382(l)(2)(B) (if losses are carried from the same taxable year, losses 
subject to limitation under section 382 are absorbed before losses that 
are not subject to limitation under section 382). See Sec. 1.1502-
21(c)(1)(iii), Example 2, for an illustration of pro rata absorption of 
losses subject to a SRLY limitation. See paragraph (b)(3)(v) of this 
section regarding the treatment of any loss that is treated as expired 
under Sec. 1.1502-35T(f)(1).
    (2) (i) through (iii) [Reserved]. For further guidance, see Sec. 
1.1502-21(b)(2) (i) through (iii).
    (iv) Operating rules--(A) Amount of CNOL attributable to a member. 
The amount of a CNOL that is attributable to a member shall equal the 
product of the CNOL and the percentage of the CNOL attributable to such 
member.
    (B) Percentage of CNOL attributable to a member--(1) In general. 
Except as provided in paragraph (b)(2)(iv)(B)(2) of this section, the 
percentage of the CNOL attributable to a member shall equal the separate 
net operating loss of the member for the year of the loss divided by the 
sum of the separate net operating losses for that year of all members 
having such losses. For this purpose, the separate net operating loss of 
a member is determined by computing the CNOL by reference to only the 
member's items of income, gain, deduction, and loss, including the 
member's losses and deductions actually absorbed by the group in the 
taxable year (whether or not absorbed by the member).
    (2) Special rule. If during a taxable year either a member realizes 
discharge of indebtedness income that is excluded from gross income 
under section 108(a) and such amount reduces any portion of the CNOL 
attributable to such member pursuant to section 108 and Sec. 1.1502-
28T, or a member that had a separate net operating loss for the year of 
the CNOL ceases to be a member, the percentage of the CNOL attributable 
to each member as of the first day of the following taxable year shall 
be recomputed. In addition, if a portion of the CNOL attributable to a 
member for a taxable year is carried back to a separate return year, the 
percentage of the CNOL attributable to each member as of the first day 
of the taxable year following the taxable year of the CNOL shall be 
recomputed. In each case, such recomputed percentage shall equal the 
unabsorbed CNOL attributable to the member on the first day of the 
following taxable year divided by the sum of the unabsorbed CNOL 
attributable to all of the members on the first day of the following 
taxable year. For purposes of the preceding sentence, a CNOL that is 
reduced pursuant to section 108 and Sec. 1.1502-28T or that is 
otherwise permanently disallowed or eliminated shall be treated as 
absorbed.
    (b)(2)(v) [Reserved]. For further guidance, see Sec. 1.1502-
21(b)(2)(v) through (b)(3)(ii)(B).
    (3) Special rules--(i) Election to relinquish carryback. A group may 
make an irrevocable election under section 172(b)(3) to relinquish the 
entire carryback period with respect to a CNOL for any consolidated 
return year. Except as provided in paragraph (b)(3)(ii)(B) of this 
section, the election may not be made separately for any member (whether 
or not it remains a member), and must be made in a separate statement 
entitled ``THIS IS AN ELECTION UNDER Sec. 1.1502-21(b)(3)(i) TO WAIVE 
THE ENTIRE CARRYBACK PERIOD PURSUANT TO SECTION 172(b)(3) FOR THE 
[insert consolidated return year] CNOLs OF THE CONSOLIDATED GROUP OF 
WHICH [insert name and employer identification number of common parent] 
IS THE COMMON PARENT''. The statement must be filed with the group's 
income tax return for the consolidated return year in which the loss 
arises. If the consolidated return year in which the loss arises begins 
before January 1, 2003, the statement making the election must be signed 
by the common parent. If the consolidated return year in which the loss 
arises begins after December 31, 2002, the election may be made in an 
unsigned statement.
    (b)(3)(ii) through (b)(3)(ii)(A) [Reserved]. For further guidance, 
see Sec. 1.1502-21 (b)(3)(ii) through (b)(3)(ii)(A).
    (B) Acquisition of member from another consolidated group. If one or 
more members of a consolidated group becomes a member of another 
consolidated group, the acquiring group may make an irrevocable election 
to relinquish, with

[[Page 362]]

respect to all consolidated net operating losses attributable to the 
member, the portion of the carryback period for which the corporation 
was a member of another group, provided that any other corporation 
joining the acquiring group that was affiliated with the member 
immediately before it joined the acquiring group is also included in the 
waiver. This election is not a yearly election and applies to all losses 
that would otherwise be subject to a carryback to a former group under 
section 172. The election must be made in a separate statement entitled 
``THIS IS AN ELECTION UNDER Sec. 1.1502-21(b)(3)(ii)(B)(2) TO WAIVE THE 
PRE-[insert first taxable year for which the member (or members) was not 
a member of another group] CARRYBACK PERIOD FOR THE CNOLs attributable 
to [insert names and employer identification number of members].'' The 
statement must be filed with the acquiring consolidated group's original 
income tax return for the year the corporation (or corporations) became 
a member. If the year in which the corporation (or corporations) became 
a member begins before January 1, 2003, the statement must be signed by 
the common parent and each of the members to which it applies. If the 
year in which the corporation (or corporations) became a member begins 
after December 31, 2002, the election may be made in an unsigned 
statement.
    (C) Partial waiver of carryback period for 2001 and 2002 losses--(1) 
Application. The acquiring group may make the elections described in 
paragraphs (b)(3)(ii)(C)(2) and (3) of this section with respect to an 
acquired member or members only if it did not file a valid election 
described in Sec. 1.1502-21(b)(3)(ii)(B) with respect to such acquired 
member or members on or before May 31, 2002.
    (2) Partial waiver of entire pre-acquisition carryback period. If 
one or more members of a consolidated group become members of another 
consolidated group after June 25, 1999, then, with respect to all 
consolidated net operating losses attributable to the member for the 
taxable year ending during either 2001 or 2002, or both, the acquiring 
group may make an irrevocable election to relinquish the portion of the 
carryback period for such losses for which the corporation was a member 
of another group, provided that any other corporation joining the 
acquiring group that was affiliated with the member immediately before 
it joined the acquiring group is also included in the waiver and that 
the conditions of this paragraph are satisfied. The acquiring group 
cannot make the election described in this paragraph with respect to any 
consolidated net operating losses arising in a particular taxable year 
if any carryback is claimed, as provided in paragraph (b)(3)(ii)(C)(4) 
of this section, with respect to any such losses on a return or other 
filing by a group of which the acquired member was previously a member 
and such claim is filed on or before the date the election described in 
this paragraph is filed. The election must be made in a separate 
statement entitled ``THIS IS AN ELECTION UNDER SECTION 1.1502-21T 
(b)(3)(ii)(C)(2) TO WAIVE THE PRE-[insert first day of the first taxable 
year for which the member (or members) was a member of the acquiring 
group] CARRYBACK PERIOD FOR THE CNOLS ATTRIBUTABLE TO THE [insert 
taxable year of losses] TAXABLE YEAR(S) OF [insert names and employer 
identification numbers of members].'' Such statement must be filed as 
provided in paragraph (b)(3)(ii)(C)(5) of this section.
    (3) Partial waiver of pre-acquisition extended carryback period. If 
one or more members of a consolidated group become members of another 
consolidated group, then, with respect to all consolidated net operating 
losses attributable to the member for the taxable year ending during 
either 2001 or 2002, or both, the acquiring group may make an 
irrevocable election to relinquish the portion of the carryback period 
for such losses for which the corporation was a member of another group 
to the extent that such carryback period includes one or more taxable 
years that are prior to the taxable year that is 2 taxable years 
preceding the taxable year of the loss, provided that any other 
corporation joining the acquiring group that was affiliated with the 
member immediately before it joined the acquiring group is also included 
in the waiver and that the conditions of

[[Page 363]]

this paragraph are satisfied. The acquiring group cannot make the 
election described in this paragraph with respect to any consolidated 
net operating losses arising in a particular taxable year if a carryback 
to one or more taxable years that are prior to the taxable year that is 
2 taxable years preceding the taxable year of the loss is claimed, as 
provided in paragraph (b)(3)(ii)(C)(4) of this section, with respect to 
any such losses on a return or other filing by a group of which the 
acquired member was previously a member and such claim is filed on or 
before the date the election described in this paragraph is filed. The 
election must be made in a separate statement entitled ``THIS IS AN 
ELECTION UNDER SECTION 1.1502-21T (b)(3)(ii)(C)(3) TO WAIVE THE PRE-
[insert first day of the first taxable year for which the member (or 
members) was a member of the acquiring group] EXTENDED CARRYBACK PERIOD 
FOR THE CNOLS ATTRIBUTABLE TO THE [insert taxable year of losses] 
TAXABLE YEAR(S) OF [insert names and employer identification numbers of 
members].'' Such statement must be filed as provided in paragraph 
(b)(3)(ii)(C)(5) of this section.
    (4) Claim for a carryback. For purposes of paragraphs 
(b)(3)(ii)(C)(2) and (3) of this section, a carryback is claimed with 
respect to a consolidated net operating loss if there is a claim for 
refund, an amended return, an application for a tentative carryback 
adjustment, or any other filing that claims the benefit of the net 
operating loss in a taxable year prior to the taxable year of the loss, 
whether or not subsequently revoked in favor of a claim based on a 5-
year carryback period.
    (5) Time and manner for filing statement. A statement described in 
paragraph (b)(3)(ii)(C)(2) or (3) of this section that relates to 
consolidated net operating losses attributable to a taxable year ending 
during 2001 must be filed with the acquiring consolidated group's timely 
filed (including extensions) original or amended return for the taxable 
year ending during 2001, provided that such original or amended return 
is filed on or before October 31, 2002. A statement described in 
paragraph (b)(3)(ii)(C)(2) or (3) of this section that relates to 
consolidated net operating losses attributable to a taxable year ending 
during 2002 must be filed with the acquiring consolidated group's timely 
filed (including extensions) original or amended return for the taxable 
year ending during 2001 or 2002, provided that such original or amended 
return is filed on or before September 15, 2003.

Sec. 1.1502-21(c)(1) through (c)(2)(vi).
    (vii) Corporations that leave a SRLY subgroup. If a loss member 
ceases to be affiliated with a SRLY subgroup, the amount of the member's 
remaining SRLY loss from a specific year is determined pursuant to the 
principles of Sec. 1.1502-21(b)(2)(ii)(A) and Sec. 1.1502-
21T(b)(2)(iv).
    (c)(2)(viii) through (h)(5) [Reserved]. For further guidance, see
