                       TITLE 26--INTERNAL REVENUE
 
    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.382-2T  Definition of ownership change under section 382, as 
amended by the Tax Reform Act of 1986 (temporary).

    (a) Ownership change--(1) In general. A corporation is a new loss 
corporation and thus subject to limitation under section 382 only if an 
ownership change has occurred with respect to such corporation. An 
ownership change occurs with respect to a corporation if it is a loss 
corporation on a testing date and, immediately after the close of the 
testing date, the percentage of stock of the corporation owned by one or 
more 5-percent shareholders has increased by more than 50 percentage 
points over the lowest percentage of stock of such corporation owned by 
such shareholders at any time during the testing period. See paragraph 
(a)(2)(i) of this section for the definition of testing date. See 
paragraph (d) of this section for the definition of testing period. See 
Sec. 1.382-2(a)(1) and paragraph (f)(3) of

[[Page 455]]

this section for the respective definition of loss corporation and new 
loss corporation. See paragraph (g) of this section for the definition 
of 5-percent shareholder. See section 383 and Sec. 1.383-1 for rules 
relating to loss corporations that have an ownership change and have 
capital loss carryovers, excess foreign taxes carried over under section 
904(c), carryovers of general business credits under section 39, or 
unused minimum tax credits under section 53.
    (2) Events requiring a determination of whether an ownership change 
has occurred--(i) Testing dates prior to November 5, 1992. Except as 
otherwise provided in this paragraph (a)(2)(i), a loss corporation is 
required to determine whether an ownership change has occurred 
immediately after any owner shift, any equity structure shift, or any 
transaction in which an option with respect to stock of the loss 
corporation is--
    (A) Transferred to (or by) a 5-percent shareholder (or a person who 
would be 5-percent shareholder if the option were treated as exercised), 
or
    (B) Issued by the loss corporation, a first tier entity, or a higher 
tier entity that owns five percent or more of the loss corporation 
(determined without regard to the application of paragraph (h)(2)(i)(A) 
of this section). Notwithstanding the preceding sentence, any transfer 
of stock of the loss corporation (or an option with respect to such 
stock) in any of the circumstances described in section 382(l)(3)(B), or 
any equity structure shift that is not also an owner shift, is not an 
event that requires the loss corporation to make a determination of 
whether an ownership change has occurred. For purposes of this section, 
each date on which a loss corporation is required to make a 
determination of whether an ownership change has occurred is referred to 
as a testing date, all computations of increases in percentage ownership 
are to be made as of the close of the testing date, and any transactions 
described in this paragraph (a)(2)(i) that occur on that date are 
treated as occurring simultaneously at the close of the testing date. 
See paragraphs (e)(1) and (2) of this section for the respective 
definitions of owner shift and equity structure shift. See paragraphs 
(f)(9) and (14) of this section for the respective definitions of first 
tier entity and higher tier entity. See paragraph (m)(4)(vii) of this 
section for special rules regarding the effective date of the provisions 
of this paragraph (a)(2)(i).
    (ii) Information statement required. A loss corporation must file a 
statement with its income tax return for each taxable year that it is a 
loss corporation in which an owner shift, equity structure shift or 
other transaction described in paragraph (a)(2)(i) of this section 
occurs. The statement must--
    (A) Indicate whether any testing dates occurred during the taxable 
year;
    (B) Identify each testing date, if any, on which an ownership change 
occurred;
    (C) Identify the testing date, if any, that occurred during and 
closest to the end of each of the three month periods ending on March 
31, June 30, September 30 and December 31 during the taxable year, 
regardless of whether an ownership change occurred on the testing date,
    (D) Identify each 5-percent shareholder on each such testing date;
    (E) State the percentage ownership of the stock of the loss 
corporation for each 5-percent shareholder as of each such testing date 
and the increase, if any, in such ownership during the testing period; 
and
    (F) Disclose the extent to which the loss corporation relied upon 
the presumptions regarding stock ownership under paragraph (k)(i) of 
this section to determine whether an ownership change occurred on any 
identified testing date.

See Sec. 1.383-1(k) and paragraph (m)(4)(v) of this section for 
transitional rules regarding the filing of information statements.
    (iii) Records to be maintained by loss corporation. A loss 
corporation shall keep such records as are necessary to determine: (A) 
The identity of its 5-percent shareholders, (B) the percentage of its 
stock owned by each such 5-percent shareholder, and (C) whether the 
section 382 limitation is applicable. Such records shall be retained so 
long as they may be material in the administration of any internal 
revenue law.

[[Page 456]]

    (b) Nomenclature and assumptions. For purposes of the example in 
this section--
    (1) L is a loss corporation, and, if there is more than one loss 
corporation, they are designated as L1, L2, 
L3, etc.
    (2) P is a corporation that is not a loss corporation, and, if there 
is more than one such corporation, they are designated as P1, 
P2, P3, etc.
    (3) HC is a corporation whose assets consist solely of the stock of 
other corporations.
    (4) E is an entity other than a corporation (e.g., a partnership), 
and, if there is more than one such entity, they are designated as 
E1, E2, E3, etc.
    (5) Unless otherwise stated--
    (i) A, B, C, D, AA, BB, CC, and DD are unrelated individuals who own 
interests in corporations or other entities only to the extent expressly 
stated,
    (ii) All corporations have one class of stock outstanding and each 
share of stock has the same fair market value as each other share,
    (iii) The capital structure of the loss corporation and its business 
do not change over time, and
    (iv) The rules of paragraphs (k)(2) and (4) of this section are not 
applicable.
    (6) Public L represents a group of unrelated individuals and 
entities that own direct (and not indirect) stock ownership interests in 
loss corporation L, each of whom owns less than five percent of the 
stock of the loss corporation, and, if there is more than one loss 
corporation, such groups are designated as Public L1, Public 
L2, Public L3, etc.
    (7) Public P represents a group of unrelated individuals and 
entities that own direct (and not indirect) stock ownership interests in 
corporation P, each of whom owns less than five percent of the stock of 
the corporation, and, if there is more than one corporation, such groups 
are designated as Public P1, P2, P3, 
etc.
    (8) Public E represents a group of unrelated individuals and 
entities that own direct (and not indirect) ownership interests in 
entity E, each of whom owns less than five percent of the entity, and, 
if there is more than one entity, such groups are designated as Public 
E1, Public E2, Public E3, etc.
    (c) Computing the amount of increases in percentage ownership--(1) 
In general. In order to determine whether an ownership change has 
occurred on a testing date, the loss corporation must identify each 5-
percent shareholder whose percentage of stock ownership in the loss 
corporation immediately after the close of the testing date has 
increased, compared to such shareholder's lowest percentage of stock 
ownership in such corporation at any time during the testing period. The 
amount of the increase in the percentage of stock ownership in the loss 
corporation of each 5-percent shareholder must be computed separately by 
comparing the percentage ownership of each such 5-percent shareholder 
immediately after the close of the testing date to such shareholder's 
lowest percentage ownership at any time during the testing period. Each 
such increase in the percentage ownership of a 5-percent shareholder is 
then added together with any other such increases of other 5-percent 
shareholders to determine whether an ownership change has occurred. 
Because only those 5-percent shareholders whose percentages of stock 
ownership have increased are taken into account, a 5-percent shareholder 
is disregarded if his percentage of stock ownership, immediately after 
the close of the testing date, has decreased (or has remained the same), 
compared to his lowest percentage ownership interest on any previous 
date during the testing period.
    (2) Example.

    Example. (i) A and B each own 40 percent of the outstanding L stock. 
The remaining 20 percent of the L stock is owned by 100 unrelated 
individuals, none of whom own as much as five percent of L stock 
(``Public L''). C negotiates with A and B to purchase all their stock in 
L.
    (ii) The acquisitions from both A and B are completed on September 
13, 1990. C's acquisition of 80 percent of L stock results in an 
ownership change because C's percentage ownership has increased by 80 
percentage points as of the testing date, compared to his lowest 
percentage ownership in L at any time during the testing period (0 
percent).

    (3) Related and unrelated increases in percentage stock ownership. 
The determination whether an ownership change has occurred is made 
without regard to

[[Page 457]]

whether the changes in stock ownership of the loss corporation (by one 
or more 5-percent shareholders) result from related or unrelated events.
    (4) Example.

    Example. (i) L has outstanding 200 shares of common stock. A, B and 
C respectively own 100, 50 and 50 shares of the L stock. On January 2, 
1988, A sells 60 shares of L stock to B. Thus, B's percentage ownership 
interest in L increases by 30 percentage points, from 50 shares to 110 
shares. On January 1, 1989, A purchases C's entire interest in L. Thus, 
A's percentage ownership interest in L increases by 25 percentage 
points, compared to his lowest percentage ownership interest in L, from 
40 shares immediately following the January 2, 1988 sale to B to 90 
shares. Even though A's ownership interest in L as of January 1, 1989 
has decreased, compared to his 50 percent ownership interest at the 
beginning of the testing period, A is a 5-percent shareholder who must 
be taken into account for purposes of the computation required under 
paragraph (c)(1) of this section because his interest in L on that 
testing date (45 percent) has increased, compared to his lowest 
percentage ownership interest in L at any time during the testing period 
(20 percent following the sale to B).
    (ii) Accordingly, although A and B jointly have increased their 
aggregate total ownership interest in L between January 2, 1988 and 
January 1, 1989 by only 25 percentage points (i.e., the total ownership 
interest in L held by A and B at all times is not less than a 75 percent 
interest), the total of their separate increases in the percentage stock 
ownership of L, compared to their respective lowest percentage ownership 
interests at any time during the testing period, is 55 percentage 
points. Thus, an ownership change occurs as a result of A's acquisition 
of L stock on January 1, 1989.

    (d) Testing period--(1) In general. Except as otherwise provided in 
paragraphs (d) and (m) of this section, the testing period for any 
testing date is the three-year period ending on the testing date. See 
paragraph (a)(2)(i) of this section for the definition of testing date.
    (2) Effect of a prior ownership change. Following an ownership 
change, the testing period for determining whether a subsequent 
ownership change has occurred shall begin no earlier than the first day 
following the change date of the most recent ownership change. See 
paragraph (f)(19) of this section for the definition of change date.
    (3) Commencement of the testing period--(i) In general. Except as 
otherwise provided in paragraph (d)(3)(ii) of this section, the testing 
period for any loss corporation shall not begin before the earlier of 
the first day of either--
    (A) The first taxable year from which there is a loss or excess 
credit carryforward to the first taxable year ending after the testing 
date, or
    (B) The taxable year in which the testing date occurs.
    (ii) Exception for corporations with net unrealized built-in loss. 
Paragraph (d)(3)(i) of this section shall not apply if the corporation 
has a net unrealized built-in loss (determined after application of 
section 382(h)(3)(B)) on the testing date, unless the loss corporation 
establishes the taxable year in which the net unrealized built-in loss 
first accrued.


In that event, the testing period shall not begin before the earlier 
of--
    (A) The first day of the taxable year in which the net unrealized 
built-in loss first accrued, or
    (B) The day described in paragraph (d)(3)(i) of this section. See 
section 382(h) for the definition of net unrealized built-in loss.
    (4) Disregarding testing dates. Any testing date that occurs before 
the beginning of the testing period shall be disregarded for purposes of 
this section.
    (5) Example.

    Example. (i) A owns all 100 outstanding shares of L stock. A sells 
40 shares to B on January 1, 1988. C purchases 20 shares of L stock from 
A on July 1, 1991. In determining if an ownership change occurs on the 
July 1, 1991 testing date, B's acquisition of L stock is disregarded 
because it occurred before the testing period that ends on such testing 
date. Thus, B's ownership interest in L does not increase during the 
testing period, and no ownership change results from C's acquisition.
    (ii) The facts are the same as in (i), except that throughout the 
period during which B negotiated his stock purchase transaction with A, 
B knew that C intended to attempt to acquire a significant stock 
interest in L. Also, B and C have been partners in a number of 
significant business ventures. The result is the same as in (i).

    (e) Owner shift and equity structure shift--(1) Owner shift--(i) 
Defined. For purposes of this section, an owner shift is any change in 
the ownership of the stock of a loss corporation that affects

[[Page 458]]

the percentage of such stock owned by any 5-percent shareholder. See 
paragraph (g) of this section for the definition of a 5-percent 
shareholder. An owner shift includes, but is not limited to, the 
following transactions:
    (A) A purchase of disposition of loss corporation stock by a 5-
percent shareholder,
    (B) A section 351 exchange that affects the percentage of stock 
owned by a 5-percent shareholder,
    (C) A redemption or a recapitalization that affects the percentage 
of stock owned by a 5-percent shareholder,
    (D) An issuance of loss corporation stock that affects the 
percentage of stock owned by a 5-percent shareholder, and
    (E) An equity structure shift that affects the percentage of stock 
owned by a 5-percent shareholder.
    (ii) Transactions between persons who are not 5-percent shareholders 
disregarded. Transfers of loss corporation stock between persons who are 
not 5-percent shareholders of such corporation (and between members of 
separate public groups resulting from the application of the segregation 
rules of paragraphs (j)(2) and (3)(iii) of this section) are not owner 
shifts and thus are not taken into account. See paragraph (h)(4)(xi) of 
this section for a similar rule applicable to transfers of options.
    (iii) Examples.

    Example (1). A has owned all 1000 shares of outstanding L stock for 
more than three years. On June 15, 1988, A sells 300 of his L shares to 
B. This transaction is an owner shift. No other 5-percent shareholder 
has increased his percentage ownership of L stock during the testing 
period. Thus, the owner shift resulting from B's acquisition does not 
result in an ownership change, because B has increased his stock 
ownership in L by only 30 percentage points.
    Example (2). The facts are the same as in Example (1). In addition, 
on June 15, 1989, L issues 100 shares to each of C, D and AA. The stock 
issuance is an owner shift. The transaction, however, does not result in 
an ownership change, because B, C, D and AA (the 5-percent shareholders 
whose stock ownership has increased as of the testing date, compared to 
any other time during the testing period) have increased their 
percentage of stock ownership in L by a total of only 46.2 percentage 
points during the testing period (by 23.1 percentage points [300 shares/
1300 shares] for B, and 7.7 percentage points [100 shares/1300 shares] 
for each of C, D and AA).
    Example (3). All 1000 shares of L stock are owned by a group of 100 
unrelated individuals, none of whom own as much as five percent of L 
stock (``Public L''). Several of the members of Public L sell their L 
stock, amounting to a 30 percent ownership interest in L, to B on June 
15, 1988. The sale of stock to B is an owner shift. Between June 16, 
1988 and June 15, 1989, each of the remaining individuals in Public L 
sells his stock to another person who is not a 5-percent shareholder. 
Under paragraph (e)(1)(ii) of this section, trading activity among the 
members of Public L is disregarded and does not result in an owner 
shift. On June 15, 1989, L issues 100 shares to each of C, D and AA. The 
only sale transactions by members of Public L that are taken into 
account in determining whether an ownership change occurs on June 15, 
1989 are the sales to B on June 15, 1988. Because B, C, D and AA 
together have increased their percentage ownership of L stock as a 
result of B's purchase and the stock issuance by an amount not in excess 
of 50 percentage points during the testing period ending on June 15, 
1988, an ownership change does not occur on that date.
    Example (4). The facts are the same as in Example (2). In addition, 
on December 15, 1989, L redeems 200 of the L shares from A. The 
redemption is an owner shift that results in an ownership change, 
because B, C, D and AA are 5-percent shareholders whose percentage 
ownership of L increase by a total of 54.6 percentage points during the 
testing period (by 27.3 percentage points [300 shares/1100 shares] for B 
and 9.1 percentage points [100 shares/1100 shares] for each of C, D and 
AA).
    Example (5). L is owned entirely by 10,000 unrelated shareholders, 
none of whom owns as much as five percent of the stock of L (``Public 
L''). Accordingly, Public L is L's only 5-percent shareholder. See 
paragraph (j)(1) of this section. There are one million shares of common 
stock outstanding. On December 1, 1988, L issues two million new shares 
of its common stock to members of the public, none of whom owned any L 
stock prior to the issuance. Following the public offering, no 
shareholder of L owns, directly or indirectly, five percent or more of L 
stock. Under paragraph (j)(2) of this section, however, all of the newly 
issued stock is treated as acquired by a 5-percent shareholder (``Public 
NL'') that is unrelated to Public L. Therefore, the public offering 
constitutes an owner shift that results in an ownership change because 
Public NL's percentage of stock ownership in L increased by 66\2/3\ 
percentage points (two million shares acquired in the public offering/
three million shares outstanding following the offering) over its lowest 
percentage ownership during

[[Page 459]]

the testing period (0 percent prior to the offering).
    Example (6). The facts are the same as in Example (5), except that L 
issues only 500,000 new shares of L stock on December 1, 1988, and 
Public NL's percentage ownership interest in L increases by only 33\1/3\ 
percentage points (500,000 shares acquired in the public offering/1.5 
million shares outstanding following the offering). During the two years 
following December 2, 1988, 14 percent of the stock outstanding on that 
date is sold over a public stock exchange. On December 3, 1990, A 
purchases five percent of L stock (75,000 shares) over a public stock 
exchange. The purchase of five percent of L stock by A is an owner shift 
and is presumed to have been made proportionately from Public L and 
Public NL under paragraph (j)(1)(vi) of this section. Under paragraph 
(e)(1)(ii) of this section, transfers of L stock in transactions not 
involving A (i.e., in transactions among or between members of separate 
public groups resulting from the application of paragraphs (j)(2) and 
(3) of this section) are not taken into account, and do not constitute 
owner shifts. (Transfers between members of Public NL and Public L, 
which are treated as separate 5-percent shareholders solely by virtue of 
paragraph (j)(2) of this section, are disregarded even if L has actual 
knowledge of any such transfers.) A and Public NL, the only 5-percent 
shareholders whose interests in L have increased during the testing 
period, have increased their respective stock ownership by only 36\2/3\ 
percentage points--five percentage points for A [75,000 shares/1.5 
million shares outstanding] and 31\2/3\ percentage points for Public NL 
[((500,000 shares issued in the public offering)--(5 percent x 500,000 
shares presumed to have been acquired by A)) /1.5 million shares 
outstanding]. Accordingly, there is no ownership change with respect to 
L notwithstanding that, taking into account the public trading, a change 
of more than 50 percentage points in the ultimate beneficial ownership 
of L stock occurred during the three-year period ending on the December 
3, 1990 testing date.
    Example 7. The facts are the same as in Example 6, except that five 
percent of the L stock has always been owned by P which, in turn, has 
always been owned by Public P. On December 6, 1990, P sells all of its L 
stock over a public stock exchange. Although the trading of P stock 
among persons that are not 5-percent share-holders (without regard to 
the segregation rules of paragraph (j) of this section) are disregarded 
under paragraph (e)(1)(ii) of this section, the disposition of the L 
stock by P is not disregarded because the L stock is transferred in a 
transaction that is subject to paragraph (j)(3)(i) of this section.

    (2) Equity structure shift--(i) Tax-free reorganizations. An equity 
structure shift is any reorganization within the meaning of section 368 
with respect to which the loss corporation is a party to the 
reorganization, except that such term does not include a reorganization 
described in--
    (A) Section 368(a)(1)(D) or (G) unless the requirements of section 
354(b)(1) are met, or
    (B) Section 368(a)(1)(F).
    (ii) Transactions designated under section 382(g)(3)(B) treated as 
equity structure shifts. [Reserved]
    (iii) Overlap of owner shift and equity structure shift. Any equity 
structure shift that affects the percentage of loss corporation stock 
owned by a 5-percent shareholder also constitutes an owner shift. See 
paragraph (e)(i)(E) of this section
    (iv) Examples.

    Example (1). A owns all of the stock of L and B owns all of the 
stock of P. On October 13, 1988, L merges into P in a reorganization 
described in section 368a(1)(A). As a result of the merger, A and B own 
25 and 75 percent, respectively, of the stock of P. The merger is an 
equity structure shift (and, because it affects the percentage of L 
stock owned by 5-percent shareholders, it also constitutes an owner 
shift). On the October 13, 1988 testing date, B is a 5-percent 
shareholder whose stock ownership in the loss corporation following the 
merger has increased by 75 percentage points over his lowest percentage 
of stock ownership in L at any time during the testing period (0 percent 
prior to the merger). Accordingly, an ownership change occurs as a 
result of the merger. P is thus a new loss corporation and L's pre-
change losses are subject to limitation under section 382.
    Example (2). (i) A owns 100 percent of L1 stock and B 
owns 100 percent of L2 stock. On January 1, 1988, 
L1 merges into L2 in a reorganization described in 
section 368(a)(1)(A). Immediately after the merger, A and B own 40 
percent and 60 percent, respectively, of the L2 stock. There 
is an equity structure shift (as well as an owner shift) with respect to 
both L1 and L2 on January 1, 1988.
    (ii) Because the percentage of L2 stock owned by B 
immediately after the merger (60 percent) increases by more than 50 
percentage points over the lowest percentage of the stock of 
L1 owned by B during the testing period (0 percent prior to 
the merger), there is an ownership change with respect to L1. 
L2 is a new loss corporation and thus, under Sec. 1.382-
2(a)(1)(iii) of this section, the pre-change losses of L1 
must be accounted for

[[Page 460]]

separately by L2 from the losses of L2 
(immediately before the ownership change) and are subject to limitation 
under section 382. See Sec. 1.382-2(a)(1)(iv) of this section for rules 
that end separate accounting for L1's pre-change losses on 
any testing date occurring on or after January 29, 1991.
    (iii) L2 is a new loss corporation because it is a 
successor corporation to L1. There is no ownership change 
with respect to L2, however, because A's stock ownership in 
L2 increased by only 40 percentage points (to 40 percent) 
over the amount owned by A prior to the merger (0 percent). Therefore, 
the pre-change losses of L2 are not limited under section 382 
as a result of the merger.
    Example (3). The result in Example (2) would be the same if 
L1 had survived the merger (i.e., L2 merged into 
L1) with A and B owning 40 and 60 percent, respectively, of 
L1 stock. L1's pre-change losses would be 
accounted for separately and limited under section 382 and the pre-
change losses of 2 would be accounted for separately under 
Sec. 1.382-2(a)(1)(iii) of this section, but would not be limited under 
section 382. See Sec. 1.382-2(a)(1)(ii) for the treatment of 
2 following the transaction.
    Example (4). The facts are the same as Example (2), except, instead 
of acquiring 1 in a merger, 2 acquires all of the 
1 stock from A on January 1, 1988, solely in exchange for 
stock representing a 40 percent interest in 2, in a 
reorganization described in section 368(a)(1)(B). The acquisition of 
stock by 2 is an equity structure shift (as well as an owner 
shift) with respect to 1 that results in an ownership change 
with respect to 1 because the percentage of 1 
stock owned by B immediately after the reorganization (60 percent, by 
virtue of B's ownership of 2, through the operation of the 
constructive ownership rules of paragraph (h) of this section) increases 
by more than 50 percentage points over the lowest percentage of 
1 stock owned by B at any time during the testing period (0 
percent prior to the reorganization). The acquisition also results in an 
equity structure shift and an owner shift with respect to 2, 
but 2 incurs no ownership change, because A's stock ownership 
in 2 increased by only 40 percentage points over the 
percentage of 2 stock owned by A prior to the reorganization 
(0 percent).

    (f) Definitions. For purposes of this section--
    (1) Loss corporation. See section 382 and Sec. 1.382-2(a)(1) for 
the definition of a loss corporation.
    (2) Old loss corporation. The term old loss corporation means any 
corporation with respect to which there is an ownership change and that 
was a loss corporation immediately before the ownership change.
    (3) New loss corporation. The term new loss corporation means a 
corporation with respect to which there is an ownership change if, 
immediately after such change, it is a loss corporation. A successor 
corporation to the corporation described in the preceding sentence also 
is a new loss corporation.
    (4) Successor corporation. See Sec. 1.382-2(a)(5) for the 
definition of successor corporation.
    (5) Predecessor corporation. See Sec. 1.382-2(a)(6) for the 
definitions of predecessor corporation.
    (6) Shift. As the context may require, a shift means an equity 
structure shift, an owner shift or both.
    (7) Entity. See Sec. 1.382-3(a)(1) for the definition of an entity.
    (8) Direct ownership interest. A direct ownership interest means the 
interest a person owns in an entity, including a loss corporation, 
without regard to the constructive ownership rules of paragraph (h) of 
this section.
    (9) First tier entity. A first tier entity is an entity that, at any 
time during the testing period, owns a five percent or more direct 
ownership interest in the loss corporation.
    (10) 5-percent owner. A 5-percent owner is any individual that, at 
any time during the testing period, owns a five percent or more direct 
ownership interest in a first tier entity or a higher tier entity. See 
paragraph (g) of this section for rules to determine whether, as a 
result of the constructive ownership rules of paragraph (h) of this 
section, a 5-percent owner is a 5-percent shareholder.
    (11) Public shareholder. A public shareholder is any individual, 
entity, or other person with a direct ownership interest in a loss 
corporation of less than five percent at all times during the testing 
period.
    (12) Public owner. A public owner is any individual, entity, or 
other person that, at all times during the testing period, owns less 
than a five percent direct ownership interest in a first tier entity or 
any higher tier entity.
    (13) Public group. A public group is a group of individuals, 
entities, or other persons each of whom owns, directly or 
constructively, less than five percent of the loss corporation. See 
paragraphs (g) and (j) of this section for the rules

[[Page 461]]

applicable to identify public groups and to determine whether a public 
group is a 5-percent shareholder.
    (14) Higher tier entity. A higher tier entity is any entity that, at 
any time during the testing period, owns a five percent or more direct 
ownership interest in a first tier entity or in any higher tier entity.
    (15) Indirect ownership interest. An indirect ownership is an 
interest a person owns in an entity determined solely as a result of the 
application of the constructive ownership rules of paragraph (h) of this 
section and without regard to any direct ownership interest (or other 
beneficial ownership interest) in the entity.
    (16) Highest tier entity. A highest tier entity is a first tier 
entity or a higher tier entity that is not owned, in whole or in part, 
at any time during the testing period by a higher tier entity.
    (17) Next lower tier entity. The next lower tier entity with respect 
to a first tier entity is the loss corporation. The next lower tier 
entity with respect to a higher tier entity is any first tier entity or 
other higher tier entity in which the higher tier entity owns, at any 
time during the testing period, a five percent or more direct ownership 
interest.
    (18) Stock--(i) In general. For further guidance, see Sec. 1.382-
2(a)(3)(i).
    (ii) Treating stock as not stock. Any ownership interest that 
otherwise would be treated as stock under paragraph (f)(18)(i) of this 
section shall not be treated as stock if--
    (A) As of the time of its issuance or transfer to (or by) a 5-
percent shareholder, the likely participation of such interest in future 
corporate growth is disproportionately small when compared to the value 
of such stock as a proportion of the total value of the outstanding 
stock of the corporation,
    (B) Treating the interest as not constituting stock would result in 
an ownership change, and
    (C) The amount of the pre-change loss (determined as if the testing 
date were the change and treating the amount of any net unrealized 
built-in loss as a pre-change loss) is more than twice the amount 
determined by multiplying
    (1) the value of the loss corporation (as determined under section 
382(e)) on the testing date, by
    (2) the long-term tax exempt rate (as defined in section 382(f)) for 
the calendar month in which the testing date occurs.

Stock that is not treated as stock under this paragraph (f)(18)(ii), 
however, is taken into account for purposes of determining the value of 
the loss corporation under section 382(e).
    (iii) Treating interests not constituting stock as stock. Any 
ownership interest that would not be treated as stock under paragraph 
(f)(18)(i) of this section (other than an option that is subject to 
paragraph (h)(4) of this section) shall be treated as constituting stock 
if--
    (A) As of the time of its issuance or transfer to (or by) a 5-
percent shareholder (or a person who would be a 5-percent shareholder if 
the interest not constituting stock were treated as stock), such 
interest offers a potential significant participation in the growth of 
the corporation,
    (B) Treating the interest as constituting stock would result in an 
ownership change, and
    (C) The amount of the pre-change losses (determined as if the 
testing date were the change date and treating the amount of any net 
unrealized built-in loss as a pre-change loss) is more than twice the 
amount determined by multiplying
    (1) The value of the loss corporation (as determined under section 
382(e)) on the testing date, by
    (2) The long-term tax exempt rate (as defined in section 382(f)) for 
the calendar month in which the testing date occurs.

An ownership interest is that treated as stock under this paragraph 
(f)(18)(iii) is taken into account for purposes of determining the value 
of the loss corporation under section 382(e). See Sec. 1.382-4(d)(12) 
for rules that apply with respect to options and this paragraph 
(f)(18)(iii).
    (iv) Stock of the loss corporation. The stock of the loss 
corporation means stock of such corporation within the meaning of this 
paragraph (f)(18) and, as the

[[Page 462]]

context may require, includes any indirect ownership interest in the 
loss corporation.
    (19) Change date. The change date means the date on which a shift 
(or any other transaction described in paragraph (a)(2)(i) of this 
section) that is the last component of an ownership change occurs.
    (20) Year. A year, or any multiple thereof, means a 365-day period 
(or a 366-day period in the case of a leap year), or any multiple 
thereof, unless the year is specifically identified as a taxable year.
    (21) Old section 382. ``Old section 382'' means section 382, as in 
effect prior to the effective date of section 382 in the Tax Reform Act 
of 1986 (the ``Act''), but taking into account section 621(f)(2) of the 
Act.
    (22) Pre-change loss. See section 382 and Sec. 1.382-2(a)(2) for 
the definition of pre-change loss.
    (23) Unrelated. Any two persons are unrelated if the constructive 
ownership rules of paragraph (h) of this section do not apply to treat 
either person as owning stock that is owned, directly or constructively, 
by the other person.
    (24) Percentage ownership interest. A person's percentage ownership 
interest in--
    (i) A corporation shall be determined under the rules of this 
section that are applicable to the determination of a shareholder's 
percentage stock ownership interest in a loss corporation (see 
paragraphs (f)(18)(i) through (iii) of this section),
    (ii) A partnership shall be equal to the relative fair market value 
of such person's partnership interest to the total fair market value of 
all outstanding partnership interests, determined without regard to any 
limited and preferred partnership interest that is described in 
paragraph (h)(2)(ii)(C) of this section,
    (iii) A trust shall be determined in accordance with the principles 
of section 318(a)(2)(B) for determining the constructive ownership of 
stock,
    (iv) An estate shall be determined in accordance with the principles 
of section 318(a)(2)(A) for determining the constructive ownership of 
stock, and
    (v) All other entities shall be determined by reference to the 
person's relative economic interest in the entity, taking into account 
all of the relevant facts and circumstances.
    (g) 5-percent shareholder--(1) In general. Subject to the rules of 
paragraphs (k)(2) and (4) of this section, the term 5-percent 
shareholder means--
    (i) An individual that owns, at any time during the testing period,
    (A) A direct ownership interest in the stock of the loss corporation 
of five percent or more or
    (B) An indirect ownership interest in the stock of the loss 
corporation of five percent or more by virtue of an ownership interest 
in any one first tier entity or higher tier entity,
    (ii) A public group, of either a first tier entity or a higher tier 
entity, identified as a 5-percent shareholder under paragraph 
(j)(1)(iv)(A) or (B) of this section,
    (iii) A public group of the loss corporation identified as a 5-
percent shareholder under paragraph (j)(1)(iv)(C) of this section, and
    (iv) A public group, of the loss corporation, a first tier entity or 
a higher tier entity, identified as a 5-percent shareholder under 
paragraph (j)(2) or (3) of this section. An individual owning five 
percent or more of the stock of the loss corporation at any time during 
the testing period is a 5-percent shareholder notwithstanding that the 
individual may own less than five percent of the stock of the loss 
corporation on the testing date. See paragraph (g)(5)(i)(B) of this 
section for rules permitting a loss corporation to make an adjustment in 
cases described in the preceding sentence.
    (2) Determination of whether a person is a 5-percent shareholder. 
Except as provided in paragraphs (k)(2) and (4) of this section, a 
person shall be treated as constructively owning stock of the loss 
corporation pursuant to paragraph (h)(2) of this section only if the 
loss corporation stock is attributed to such person in the person's 
capacity as a higher tier entity or a 5-percent owner of the first tier 
entity or higher tier entity from which such stock is attributed. See 
paragraph (k)(3) of this section for rules explaining the extent of the 
obligation of the loss corporation to determine the identity of its 5-
percent shareholders. Nothing in this

[[Page 463]]

paragraph (g)(2), however, shall limit the attribution of loss 
corporation stock under section 318(a)(2) and paragraph (h) of this 
section to a public owner.
    (3) Determination of the percentage stock ownership interest of a 5-
percent shareholder. Subject to the rules of paragraphs (k)(2) and (4) 
of this section, in determining a 5-percent shareholder's percentage 
ownership interest in the loss corporation, the shareholder's direct 
ownership interest, if any, and each indirect ownership interest that he 
may have in the loss corporation in his capacity as a 5-percent owner of 
any one first tier entity or higher tier entity, if any, are required to 
be added together and taken into account with respect to such 
shareholder only to the extent that each such direct or indirect 
ownership interest constitutes five percent or more of the stock of the 
loss corporation.
    (4) Examples.

    Example (1) (i) Twenty percent of L stock is owned by A, 10 percent 
is owned by P1, 20 percent is owned by E, a joint venture, 
and the remaining 50 percent of L stock is owned by Public L. 
P1 is owned 15 percent by B and 85 percent by Public 
P1. E is owned 30 percent by P2 and 70 percent by 
P3, which, in turn, are owned by Public P2 and 
Public P3, respectively.
    (ii) The ownership structure of L is illustrated by the following 
chart:
[GRAPHIC] [TIFF OMITTED] TC17OC91.002

    (iii) P1 and E, each of which has a direct ownership 
interest in L of five percent or more, are first tier entities. The 
shareholders with direct ownership interests in L who individually own 
less than five percent of L are public shareholders (Public L). B, who 
has a direct ownership interest of five percent or more in 
P1, is a 5-percent owner of

[[Page 464]]

P. P2 and P3, and P3, each of which has 
a direct ownership interest in a first tier entity (E) of five percent 
or more, are higher tier entities with respect to L and, because neither 
entity is owned at any time during the testing period by a higher tier 
entity, they also are highest tier entities. The shareholders of 
P2 and P3 (Public P2 and Public 
P3, respectively) are public owners of such entities, because 
none of those shareholders own five percent or more of either entity at 
any time during the testing period.
    (iv) A, who has a 20 percent direct ownership interest in L, is a 5-
percent shareholder of L. Because, by application of the constructive 
ownership rules of paragraph (h) of this section, B owns only 1.5 
percent of L stock in his capacity as a 5-percent owner of P1 
(15 percent ownership of P1 x 10 percent ownership of L), B 
is not a 5-percent shareholder of L, even though he is a 5-percent owner 
of P1. Under the rules of paragraph (j) of this section, 
therefore, B is treated as a member of Public P1. See Example 
(3) of paragraph (j)(1)(vi) of this section for a determination of which 
public owners and public shareholders constitute public groups that are 
treated as 5-percent shareholders of L.
    Example (2) (i) The facts are the same as in Example (1), except 
that P3 is owned 60 percent by C, 30 percent by 
P4, and 10 percent by Public P3. The stock of 
P4 is owned by a group of persons (Public P4), 
none of whom own five percent or more of the stock of P4.
    (ii) The ownership structure of L is illustrated by the following 
chart:

[[Page 465]]

[GRAPHIC] [TIFF OMITTED] TC17OC91.003

    (iii) The defined terms are the same as in Example (1), except that 
P3 is a higher tier entity, not a highest tier entity, 
because five percent or more of P3 is, in turn, owned by 
another entity (P4 ). P4, which owns five percent 
or more of a higher tier entity (P3), also is a higher tier 
entity and, because it is not owned at any time during any testing 
period by any entity that is also a higher tier entity, P4 is 
a highest tier entity. All of the shareholders of P4, none of 
which own a direct ownership interest of five percent or more in 
P4, are public owners of P4.
    (iv) C is a 5-percent owner of P3 and, under the 
constructive ownership rules of paragraph (h) of this section, C 
indirectly owns 8.4 percent of L ([60 percent ownership of 
P3] x [70 percent ownership of E] x [20 percent ownership of 
L]), in his capacity as a 5-percent owner of P3. B is a 5-
percent owner of P1 and, under the constructive ownership 
rules of paragraph (h) of his section, B owns 1.5 percent of L ([15 
percent ownership of P1] x [10 percent ownership of L]) in 
his capacity as a 5-percent owner of P1. Therefore, C is a 5-
percent shareholder of L, but B is not a 5-percent shareholder of L, 
even though he is a 5-percent owner of P1. See Example (4) of

[[Page 466]]

paragraph (j)(1)(vi) of this section for a determination of which public 
owners and public shareholders constitute public groups that are treated 
as separate 5-percent shareholders of L.
    Example (3) (i) L is owned 30 percent by A and 70 percent by P. A 
owns six percent of P stock and the balance (94 percent) is owned 
equally by 500 unrelated shareholders (``Public P'').
    (ii) A is a 5-percent shareholder because he directly owns 30 
percent of L. Even though A is a 5-percent owner of P, A's 4.2 percent 
indirect ownership interest in L (six percent ownership interest in P x 
P's 70 percent ownership of L) is generally not taken into account in 
determining A's ownership interest, because such indirect ownership 
interest is less than five percent. Instead, A's 4.2 percent indirect 
interest is treated under paragraph (j)(1)(iv) of this section as owned 
by Public P. If, however, L has actual knowledge of A's less-than-five-
percent indirect ownership interest in L and is thus subject to 
paragraph (k)(2) of this section, or paragraph (k)(4) of this section 
otherwise applies, L must take A's total 34.2 percent ownership interest 
into account in determining A's percentage ownership in L.
    Example (4). The facts are the same as in Example (3), except that A 
owns ten percent of P's stock. Because A's indirect ownership interest 
in L in his capacity as a 5-percent owner of P is five percent or more, 
both A's 30 percent direct ownership interest in L and his seven percent 
indirect ownership interest in L (10 percent ownership interest in P x 
P's 70 percent ownership of L) are taken into account in determining his 
ownership interest in L, without regard to L's actual knowledge or 
whether paragraph (k)(4) of this section applies.
    Example 5 See Sec. 1.382-3(a)(1)(ii) for additional examples with 
respect to the definition of an entity.

    (5) Stock ownership presumptions in connection with certain 
acquisitions, and dispositions of loss corporation stock--(i) In 
general. For purposes of this section--
    (A) If an individual owns less than five percent of the stock of a 
loss corporation during the testing period (excluding the testing date) 
and acquires an amount of such stock so that the individual becomes a 5-
percent shareholder on the testing date, the loss corporation may treat 
any interest in the loss corporation owned by such individual prior to 
that acquisition as owned by a public group during the period of such 
individual's ownership of that interest and as not owned by the 5-
percent shareholder during the same period, and
    (B) If a 5-percent shareholder's percentage ownership interest in 
the loss corporation is reduced to less than five percent, the loss 
corporation may presume that the remaining stock owned by such 5-percent 
shareholder immediately after such reduction is the stock owned by such 
shareholder for each subsequent testing date having a testing period 
that includes the date on which the reduction occurred as long as such 
shareholder continues to own less than five percent of the stock of the 
loss corporation. In that event, such ownership interest shall be 
treated as owned by a separate public group for purposes of the rules of 
paragraph (j)(2)(vi) of this section.
    (ii) Example.

     standing. All of the L stock is owned equally by 40 unrelated, 
individual shareholders, including A (who owns 2.5 percent of L stock). 
Because no person owns as much as five percent of L stock, Public L is 
the only 5-percent shareholder of L. See paragraph (j)(1) of this 
section. A purchases 5,000 shares of L stock over a public stock 
exchange on June 8, 1989. The purchase is an owner shift. When added to 
his ownership interest before that date (the testing date), A owns 7,500 
shares of L stock (7.5 percent). Under paragraph (g)(5)(i)(A) of this 
section, L may treat A and Public L as having owned 0 percent and 100 
percent, respectively, at all times prior to June 8, 1989 (rather than 
having owned 2.5 percent by A and 97.5 percent by Public L, even if L 
has actual knowledge of A's less than five percent ownership interest). 
The increase in A's stock ownership of L as of June 8, 1989 thus would 
be 7.5 percentage points, rather than 5.0 percentage points, for 
purposes of determining whether an ownership change occurs on that 
testing date and any subsequent testing date.

    (h) Constructive ownership of stock--(1) In general. Subject to 
certain modifications set forth in this section and section 382(l)(3), 
the constructive ownership rules of section 318(a) generally apply for 
purposes of determining ownership of loss corporation stock.
    (2) Attribution from corporations, partnerships, estates and 
trusts--(i) In general. Stock owned (directly or indirectly) by an 
entity shall be attributed to its owners--

[[Page 467]]

    (A) Except as otherwise provided in this section, by treating the 
stock attributed pursuant to section 318(a)(2) as no longer being owned 
by the entity from which it is attributed, and
    (B) If attribution is from a corporation, without regard to the 50 
percent stock ownership limitation contained in section 318(a)(2)(C).
    (ii) Limitation on attribution from entities with respect to certain 
interests. Section 318(a)(2) shall not apply to treat the stock of the 
loss corporation that is owned directly by a first tier entity (or 
indirectly by any higher tier entity) as being indirectly owned by any 
person that has an ownership interest in the first tier entity (or any 
higher tier entity) to the extent that such interest is (or is 
attributable to)--
    (A) Stock of any such entity that is described in section 
1504(a)(4),
    (B) Any ownership interest in any such entity that does not 
constitute stock under paragraph (f)(18)(ii) of this section, or
    (C) If the entity is not a corporation, any ownership interest in 
any such entity that has characteristics similar to the interests 
described in paragraph (h)(2)(ii)(A) or (B) of this section.

The ownership interests described in this paragraph (h)(2)(ii) shall not 
be taken into account in determining a person's percentage ownership 
interest in an entity under paragraph (f)(24) of this section.
    (iii) Limitation on attribution from certain entities. For purposes 
of this section, except as provided in paragraphs (k)(2) and (4) of this 
section, each of the following shall be treated as an individual who is 
unrelated to any other owner (direct or indirect) of the loss 
corporation--
    (A) Any entity other than a higher tier entity that owns five 
percent or more of the loss corporation stock (determined without regard 
to paragraph (h)(2)(i)(A) of this section) on a testing date, a first 
tier entity or the loss corporation,
    (B) A qualified trust described in section 401(a),
    (C) Any State, any possession of the United States, the District of 
Columbia, the United States (or any agency or instrumentality thereof), 
any foreign government, or any political subdivision of any of the 
foregoing, and
    (D) Any other person designated by the Internal Revenue Service in 
the Internal Revenue Bulletin.

Stock of a loss corporation that is owned by any such person shall thus 
not be attributed to any other person for purposes of this section. See 
paragraph (g)(2) of this section limiting attribution from a first tier 
entity or a higher tier entity to any person that is not a 5-percent 
owner or a higher tier entity.
    (iv) Examples.

    Example (1). All the stock of L is owned by A. B and C respectively 
own 70 and 30 percent of the outstanding P stock. P acquires 60 percent 
of the outstanding L stock from A on July 1, 1988 (a testing date). 
After the acquisition, P is a first tier entity and a higher tier entity 
of L. B and C are each 5-percent owners of P and also are 5-percent 
shareholders of L having a 42 percent and 18 percent stock ownership 
interest in L, respectively, through the operation of the constructive 
ownership rules of paragraph (h) of this section. Because B and C 
together have increased their ownership in L by more than 50 percentage 
points during the testing period ending on the testing date (60 percent 
on the testing date and 0 percent prior thereto), an ownership change 
occurs with respect to L on July 1, 1988.
    Example (2). The facts are the same as in Example (1), except that B 
and C are not shareholders in a corporation, but instead are partners in 
a general partnership, E. B and C respectively own 70 percent and 30 
percent of E. E acquires 60 percent of the L stock on July 1, 1988. The 
results are the same as in Example (1).
    Example (3). The facts are the same as in Example (1), except that 
the acquisition is accomplished in a transaction that qualifies under 
section 351(a). In that transaction, HC is formed through (i) a 
contribution of money by P in exchange for 60 shares of HC common stock 
and (ii) a contribution of all the outstanding shares of L stock plus 
cash by A in exchange for 40 shares of HC common stock and 30 shares of 
HC preferred stock that is described in section 1504(a)(4). The 
respective values of each share of HC stock, common and preferred, are 
equal. The stock of L is attributed to A through his interest in HC 
common stock, but not through his interest in HC preferred stock (see 
paragraph (h)(2)(ii)(A) of this section). Thus, A is treated as owning 
indirectly only 40 percent of L. B and C are 5-percent shareholders of L 
having indirect ownership interests in L of 42 percent and 18 percent, 
respectively, through their ownership of HC common stock. The

[[Page 468]]

results are therefore the same as in Example (1).

    (3) Attribution to corporations, partnerships, estates and trusts. 
Except as otherwise provided by regulation under section 382 or by the 
Internal Revenue Service in the Internal Revenue Bulletin, the rules of 
section 318(a)(3) shall not apply in determining the ownership of stock 
under this section.
    (4) Option attribution--(i) In general. Solely for the purpose of 
determining whether there is an ownership change on any testing date, 
stock of the loss corporation that is subject to an option shall be 
treated as acquired on any such date, pursuant to an exercise of the 
option by its owner on that date, if such deemed exercise would result 
in an ownership change. The preceding sentence shall be applied 
separately with respect to--
    (A) Each class of options (i.e., options with terms that are 
identical, issued by the same issuer, and issued on the same date) owned 
by each 5-percent shareholder (or person who would be a 5-percent 
shareholder if the option were treated as exercised), and
    (B) Each 5-percent shareholder, each owner of an option who would be 
a 5-percent shareholder if the option were treated as exercised, and 
each combination of such persons.
    (ii) Examples.

    Example (1). (i) A owns all of the 100 shares of outstanding L 
stock. A grants options for the purchase of his L stock, exercisable for 
10 years from the date of issuance, in the following transactions: An 
option to B for four shares (issued January 1, 1988), an option to C for 
six shares (issued June 1, 1989), and an option to D for 15 shares 
(issued July 30, 1989). On July 30, 1990, A sells 41 shares of his L 
stock to BB.
    (ii) Pursuant to paragraph (a)(2)(i) of this section, the date on 
which each option is acquired is a testing date. The issuance of options 
to acquire L stock to each of B, C, and D is not treated as an 
acquisition of the underlying stock on any such testing date since such 
treatment with respect to any one of the option owners (or any 
combination thereof) would not have resulted in an ownership change on 
any of those testing dates.
    (iii) The date on which BB acquires 41 shares also is a testing 
date. BB's acquisition of 41 percent of the L stock, taken together with 
the shift in ownership that would result if the options held by B, C and 
D were exercised, would result in an ownership change, because the stock 
owned or treated as owned by Public L (a group including only B, the 
sole shareholder who owns less than five percent of L stock), C, D and 
BB would have increased by 66 percentage points (four, six, 15, and 41 
percentage points, respectively) during the testing period. Subject to 
paragraph (h)(4)(ix) of this section, the options are treated as 
exercised and an ownership change occurs on July 30, 1990, pursuant to 
paragraph (h)(4)(i) of this section. Accordingly, no new testing period 
can begin before July 31, 1990. Under paragraph (h)(4)(x)(F) of this 
section, the option attribution rules of paragraph (h)(4)(i) of this 
section shall not be applicable with respect to any of the options owned 
by B, C, and D immediately before the ownership change until such time, 
if any, that such options are transferred to (or by) 5-percent 
shareholder (or a person who would be a 5-percent shareholder if such 
option were exercised). In addition, the subsequent exercise of any of 
those options by A, B, or C (the persons owning such options immediately 
before the ownership change) is disregarded. See paragraph (h)(4)(vi) of 
this section. Also see paragraph (h)(4)(viii) of this section for the 
treatment of options that lapse or are forfeited.
    (iv) The facts are the same as in (i), except that the sale of A's 
41 shares of L stock to BB occurs on July 30, 1995. Because the options 
are treated as exercised and the related stock is treated as acquired on 
the July 30, 1995 testing date, the results are the same as described in 
(iii).
    Example (2) (i) A owns all of the outstanding 100 shares of the 
stock of L. On July 22, 1988, the value of A's stock in L is $500 and 
the following agreements are entered into: (i) A sells 40 shares of his 
L stock to B for $200, (ii) in exchange for $10, A grants B an option to 
acquire the balance of his L stock for $305 at any time before July 22, 
1992, and (iii) L grants A an option to acquire 100 shares of L stock at 
a price of $600 exercisable until such time as B's option is no longer 
outstanding.
    (ii) If the stock subject to the options owned by both A and B were 
treated as acquired on the July 22, 1988 testing date, B would have 
increased his ownership interest in L by only 50 percentage points to 50 
percent ([40 shares purchased + 60 shares acquired pursuant to the 
option]/200 outstanding shares of L stock, including 100 shares deemed 
outstanding pursuant to the option issued to A by L) as compared with 0 
percent prior to July 22, 1988. In determining whether the options with 
respect to the stock of L would, if exercised, result in an ownership 
change, paragraph (h)(4)(i)(B) of this section requires that such 
options be treated as exercised separately with respect to each 5-
percent shareholder, each person who would be a 5-percent shareholder if 
the option were treated as exercised or each

[[Page 469]]

combination of such persons. Therefore, by treating the option owned by 
A as not having been exercised and the option owned by B as having been 
exercised, B's interest in L increases by 100 percentage points during 
the testing period. An ownership change with respect to L therefore 
results from the transactions occurring on July 22, 1988.

    (iii) Contingencies. Except as provided in paragraph (h)(4)(x)(D) of 
this section, the extent to which an option is contingent or otherwise 
not currently exercisable shall be disregarded for purposes of this 
section.
    (iv) Series of options. For purposes of this section, an option to 
acquire an option with respect to the stock of the loss corporation, and 
each one of a series of such options, shall be considered as an option 
to acquire such stock.
    (v) Interests that are similar to options. For purposes of this 
section,
    (A) An interest that is similar to an option includes, but is not 
limited to, a warrant, a convertible debt instrument, an instrument 
other than debt that is convertible into stock, a put, a stock interest 
subject to risk of forfeiture, and a contract to acquire or sell stock, 
and
    (B) Any such interest shall be treated as an option.
    (vi) Actual exercise of options--(A) In general. The actual exercise 
of any option in existence immediately before and after an ownership 
change, whether or not the option was treated as exercised in connection 
with the ownership change under paragraph (h)(4)(i) of this section, 
shall be disregarded for purposes of this section, but only if the 
option is exercised by the 5-percent shareholder (or person who would 
have been a 5-percent shareholder if the options owned by such person 
had been exercised immediately before the ownership change) who owned 
the option immediately before and after such ownership change.
    (B) Actual exercise within 120 days of deemed exercise. If the 
actual exercise of an option occurs on or before the end of the period 
which is 120 days after the date on which the option is treated as 
exercised under paragraph (h)(4)(i) of this section, the loss 
corporation may elect to treat paragraphs (h)(4)(i) and (vi)(A) of this 
section as not applying to such option and take into account only the 
acquisition of loss corporation stock resulting from the actual exercise 
of the option. An election under this paragraph (h)(4)(vi)(B) shall have 
no effect on the determination of whether an ownership change occurs, 
but shall apply only for the purpose of determining the date on which 
the change date occurs. An election under this paragraph (h)(4)(vi)(B) 
shall be made in the statement described in paragraph (a)(2)(ii) of this 
section.
    (vii) Effect of deemed exercise of options on the outstanding stock 
of the loss corporation--(A) Right or obligation to issue stock. Solely 
for purposes of determining whether an ownership change has occurred 
under paragraph (h)(4)(i) of this section, the deemed exercise of an 
option with respect to unissued stock (or treasury stock) of a 
corporation shall result in a corresponding increase in the amount of 
its total outstanding stock.
    (B) Right or obligation to acquire outstanding stock by the loss 
corporation. Solely for purposes of determining whether an ownership 
change has occurred under paragraph (h)(4)(i) of this section, the 
deemed exercise of a right to transfer outstanding stock to the issuing 
corporation (or a right of the issuing corporation to acquire its stock) 
shall result in a corresponding decrease in the amount of its total 
outstanding stock.
    (C) Effect on value of old loss corporation. The deemed exercise of 
an option with respect to unissued stock (or treasury stock) under 
paragraph (h)(4)(i) of this section shall have no effect on the 
determination of the value of the old loss corporation and the 
computation of the section 382 limitation. See section 382(l)(1)(B) 
disregarding capital contributions made during the two-year period 
preceding the change date for purposes of computing the section 382 
limitation.
    (viii) Options that lapse or are forfeited. If an option that is 
treated as exercised under paragraph (h)(4)(i) of this section lapses 
unexercised or the owner of such option irrevocably forfeits his right 
to acquire stock pursuant to the option, the option shall be treated for 
purposes of this section as if it never had been issued. In that case, 
the loss

[[Page 470]]

corporation may file an amended return for prior years (subject to any 
applicable statute of limitations) if the section 382 limitation was 
thus inapplicable. If paragraph (h)(4)(i) of this section applied to an 
option (or options) with respect to a taxable year for which an income 
tax return has not been filed by the date that the option (or options) 
lapses or is irrevocably forfeited, the loss corporation may treat 
paragraph (h)(4)(i) of this section as inapplicable to such option (or 
options).
    (ix) Option rule inapplicable if pre-change losses are de minimis. 
Paragraph (h)(4)(i) of this section shall not apply to treat the stock 
of the loss corporation as acquired by the owner of an option if, on a 
testing date, the amount of pre-change losses (determined as if the 
testing date were a change date and treating the amount of any net 
unrealized built-in loss as a pre-change loss) is less than twice the 
amount determined by multiplying.
    (A) The value of the loss corporation (as determined under section 
382(e)) on the testing date, by
    (B) The long-term tax exempt rate (as defined in section 382(f)) for 
the calendar month in which the testing date occurs.
    (x) Options not subject to attribution. Paragraph (h)(4)(i) of this 
section shall not apply to--
    (A) Long-held options with respect to actively traded stock. Any 
option with respect to stock of the loss corporation which stock is 
actively traded on an established securities market (within the meaning 
of section 1273(b)) for which market quotations are readily available, 
if such option has been continuously owned by the same 5-percent 
shareholder (or a person who would be a 5-percent shareholder if such 
option were exercised) for at least three years, but only until the 
earlier of such time as--
    (1) The option is transferred by or to a 5-percent shareholder (or a 
person who would be a 5-percent shareholder if such option were 
exercised), or
    (2) The fair market value of the stock that is subject to the option 
exceeds the exercise price for such stock on the testing date. For 
purposes of this paragraph (h)(4)(x)(A), options with respect to the 
stock of a loss corporation that are assumed (or substituted) in a 
reorganization and converted into options with respect to the stock of 
another party to the reorganization shall not be treated as transferred, 
provided that there are no changes in the terms of the options, other 
than that the stock that may be acquired pursuant to the option is that 
of another party to the reorganization and that the amount of stock 
subject to the option is adjusted only to reflect the exchange ratio for 
the exchange of stock of the loss corporation in the reorganization.
    (B) Right to receive or obligation to issue a fixed dollar amount of 
value of stock upon maturity of certain debt. Any right to receive or 
obligation to issue stock pursuant to the terms of a debt instrument 
that, in economic terms, is equivalent to nonconvertible debt because 
the right to receive stock of the issuer of a fixed dollar amount is 
based upon the fair market value for such stock determined at or about 
the date the stock is transferred pursuant to such right or obligation 
(i.e., the amount of the stock transferred pursuant to the option is 
equal to a fixed dollar amount, divided by the value of each share of 
such stock at or about the date of the stock transfer). This paragraph 
(h)(4)(x)(B) shall not apply if the method for determining the fair 
market value of the stock of the issuer is intended to or, in fact, 
provides the owner of the debt instrument with a participation in any 
appreciation of any stock of the issuer.
    (C) Right or obligation to redeem stock of the loss corporation. Any 
right or obligation of the loss corporation to redeem any of its stock 
at the time such stock is issued, but only to the extent such stock is 
issued to persons who are not 5-percent shareholders immediately before 
the issuance.
    (D) Options exercisable only upon death, disability or mental 
incompetency. Any option entered into between owners of the same entity 
(or an owner and the entity in which the owner has a direct ownership 
interest) with respect to such owner's ownership interest in the entity 
that is exercisable only upon the death, complete disability or mental 
incompetency of such owner.
    (E) Right to receive or obligation to issue stock as interest or 
dividends. Any

[[Page 471]]

right to receive or obligation to issue stock of a corporation in 
payment of interest or dividends by the issuing corporation. (For an 
example illustrating this exception, see paragraph (j)(2)(iv)(B) of this 
section.)
    (F) Options outstanding following an ownership change--(1) In 
general. Any option in existence immediately before and after an 
ownership change, whether or not the option was treated as exercised in 
connection with the ownership change under paragraph (h)(4)(i) of this 
section, but only so long as the option continues to be owned by the 5-
percent shareholder (or person who was treated as a 5-percent 
shareholder) who owned the option immediately before and after such 
ownership change.
    (2) Example (i) A, B, C and D own all of the outstanding stock of L. 
A owns 70 shares of L stock and each of B, C and D own 10 shares of L 
stock. On July 12, 1988, L issues warrants to each of its shareholders 
entitling them to acquire an additional 8.5 shares of L stock for each 
share of stock owned. (ii) If B, C and D, but not A, each exercise their 
respective rights to acquire an additional 85 shares of L stock (10 
shares x 8.5 shares that may be acquired for each share owned) on July 
12, 1988, their combined ownership interest in L on that date would 
exceed 80 percent (255 shares deemed to be acquired + 30 shares actually 
owned)/355 shares outstanding (actual and deemed)). B, C and D thus 
would increase their ownership interest in L by 50.3 percentage points 
during the testing period, causing an ownership change, because, under 
paragraph (h)(4)(i)(B) of this section, the options are treated as 
exercised if the exercise would cause an ownership change.
    (iii) Following the ownership change, paragraph (h)(4)(i) of this 
section applies to prevent A's right to acquire 595 shares of L stock 
(70 shares x 8.5 shares that may be acquired for each share owned) or 
the rights held by B, C, or D, to be treated as exercised on any 
subsequent testing date, except to the extent that those rights are 
transferred. To the extent any of those options are transferred 
following the ownership change, paragraph (h)(4)(i) of this section will 
apply to any such options on the date of the transfer and on any 
subsequent testing date.

    (G) Right to acquire loss corporation stock pursuant to a default 
under a loan agreement. Any right to acquire stock of a corporation by a 
bank (as that term is defined in section 581), an insurance company (as 
that term is defined in Sec. 1.801-3(a)), or a trust qualified under 
section 401(a) solely as the result of a default under a loan agreement 
entered into in the ordinary course of the trade or business of such 
bank, life insurance company or qualified trust.
    (H) Agreement to acquire or sell stock owned by certain shareholders 
upon retirement. Any option entered into between noncorporate owners of 
the same entity (or a noncorporate owner and the entity in which the 
owner has a direct ownership interest) with respect to such owner's 
ownership interest in the entity, but only if each of such owners 
actively participate in the management of the entity's trade or 
business, the option is issued at a time that the loss corporation is 
not a loss corporation and the option is exercisable solely upon the 
retirement of such owner. An option with terms described in both this 
paragraph (h)(4)(x)(H) and in paragraph (h)(4)(x)(D) of this section 
shall also not be subject to paragraph (h)(4)(i) of this section.
    (I) [Reserved]
    (J) Title 11 or similar case. See Sec. 1.382-9(o) which excepts 
certain options created by or under a plan of reorganization in a title 
11 or similar case from the operation of paragraph (h)(4)(i) of this 
section.
    (K)-(Y) [Reserved]
    (xi) Certain transfers of options disregarded. Transfers of options 
between persons who are not 5-percent shareholders (and between members 
of separate public groups resulting from the application of the 
segregation rules of paragraphs (j)(2) and (3)(iii) of this section) are 
not taken into account. Transfers of options in any of the circumstances 
described in section 382(l)(3)(B) are also disregarded and the 
transferee shall be treated as having owned the option for the period 
that it was owned by the transferor.
    (xii) Exercise of an option that has not been treated as stock. The 
acquisition of stock pursuant to the actual exercise of an option (other 
than an option described in paragraph (h)(4)(vi)(A) of this section) 
shall not be disregarded.
    (xiii) Effective date. See paragraph (m)(4)(vi) of this section for 
special rules regarding the effective date of the provisions of this 
paragraph (h)(4).
    (5) Stock transferred under certain agreements. Notwithstanding 
paragraph (h)(4) of this section, no shift results solely because under 
section 1058(a)--

[[Page 472]]

    (i) A shareholder transfers stock of a corporation pursuant to an 
agreement that meets the requirements of section 1058(b), or
    (ii) A person having rights under such an agreement exchanges those 
rights for stock identical to the stock transferred pursuant to the 
agreement.
    (6) Family attribution. For purposes of this section--
    (i) Paragraphs (1) and (5)(B) of section 318(a) shall not apply,
    (ii) An individual and all members of his family described in 
section 318(a)(1) shall be treated as one individual,
    (iii) Subject to paragraph (k)(2) of this section, paragraph 
(h)(6)(ii) of this section shall not apply to members of a family who, 
without regard to that paragraph (h)(6)(ii), would not be 5-percent 
shareholders, and
    (iv) If under paragraph (h)(6)(ii) of this section, an individual 
may be treated as a member of more than one family, and each family that 
is treated as one individual is a 5-percent shareholder (or would be 
treated as a 5-percent shareholder if such individual were treated as a 
member of such family), then such individual shall be treated only as a 
member of the family that results in the smallest increase in the total 
percentage stock ownership of the 5-percent shareholders on the testing 
date and shall not be treated as the member of any other family.
    (i) [Reserved]
    (j) Aggregation and segregation rules. For purposes of this section, 
except as provided in paragraphs (k)(2) and (4) of this section--
    (1) Aggregation of public shareholders and public owners into public 
groups--(i) Public group. Under this paragraph (j), a loss corporation 
or other entity can be treated as owned, in whole or in part, by one or 
more public groups. A public group can include public shareholders, 
public owners, and 5-percent owners who are not 5-percent shareholders 
of the loss corporation.
    (ii) Treatment of a public group that is a 5-percent shareholder. 
Each public group that is treated as a 5-percent shareholder under 
paragraph (g)(1)(ii), (iii) or (iv) of this section shall be treated as 
one individual. See paragraph (j)(2)(iv) for a rule combining certain de 
minimis public groups.
    (iii) Presumption of no cross-ownership. The public owners, 5-
percent owners who are not 5-percent shareholders and public 
shareholders in any public group, subject to paragraphs (j)(2)(iii), 
(k)(2) and (k)(4) of this section, are presumed not to be members of any 
other public group. It also is presumed that each such person is 
unrelated to all other shareholders (direct and indirect) of the loss 
corporation. See paragraph (h)(6)(iii) of this section. The members of a 
public group that exists by virtue of its direct ownership interest in 
an entity are presumed not to be members (and not to be related to a 
member) of any other public group that exists at any time by virtue of 
its direct ownership interest in any other entity. To the extent that 
the presumptions adopted in this paragraph (j)(1)(iii) are not 
applicable because the loss corporation has actual knowledge of facts to 
the contrary and is thus subject to paragraph (k)(2) of this section, 
public shareholders, public owners and 5-percent owners who are not 5-
percent shareholders may be aggregated into additional public groups.
    (iv) Identification of the public groups treated as 5-percent 
shareholders--(A) Analysis of highest tier entities. The loss 
corporation must identify first tier entities and higher tier entities 
in order to identify any highest tier entities that must be identified 
under paragraph (k)(3) of this section. The loss corporation must then 
identify any 5-percent owners of each such highest tier entity who 
indirectly own, at any time during the testing period, five percent or 
more of the loss corporation through the ownership interest in such 
highest tier entity. Under paragraph (g)(1)(i)(B) of this section, any 
such 5-percent owner is a 5-percent shareholder. See paragraph (k)(3) of 
this section for rules explaining the extent of the obligation of the 
loss corporation to determine the identity of its shareholders. Each 
person who has an ownership interest in any highest tier entity and who 
is not treated as a 5-percent shareholder (i.e., persons who are public 
owners or 5-percent owners who are not 5-percent shareholders) is a 
member of the public group of that highest tier entity. A public group, 
so identified, that indirectly owns five percent

[[Page 473]]

or more of the loss corporation on the testing date is treated under 
paragraph (g)(1)(ii) of this section as a 5-percent shareholder. If the 
public group so identified owns less than five percent of the loss 
corporation on the testing date, such public group is treated as part of 
the public group of the next lower tier entity.
    (B) Analysis of other higher tier entities and first tier entities. 
The analysis and aggregation of public groups described in paragraph 
(j)(1)(iv)(A) of this section is repeated for any next lower tier entity 
and successively for any next lower tier entity of any entity described 
in this paragraph (j)(1)(iv)(B) until applied to each first tier entity.
    (C) Aggregation of the public shareholders. The public shareholders 
are aggregated and, under paragraph (g)(1)(iii) of this section, are 
treated as a public group that is a 5-percent shareholder without regard 
to whether such group, at any time during the testing period, owns five 
percent or more of the loss corporation. For this purpose, if the public 
group of any first tier entity indirectly owns less than five percent of 
the loss corporation on the testing date, and is thus not treated as a 
5-percent shareholder, but is treated as part of the public group of the 
loss corporation under paragraph (j)(1)(iv)(A) or (B) of this section, 
the ownership interest of that group is included in the public group of 
the loss corporation referred to in the preceding sentence.
    (v) Appropriate adjustments. A loss corporation may apply the 
principles of paragraph (g)(5) of this section with respect to--
    (A) Any public group that is treated as a 5-percent shareholder on 
the testing date if such public group, at any time during the testing 
period, was treated as part of the public group of the next lower tier 
entity, or
    (B) Any public group that is treated as part of the public group of 
a next lower tier entity if such public group, at any time during the 
testing period, was part of the public group of a higher tier entity 
that was treated as a 5-percent shareholder and had a direct or indirect 
ownership interest in such lower tier entity.
    (vi) Examples.

    Example (1) (i) All of the stock of L is owned by 1,000 
shareholders, none of whom own as much as five percent of L stock 
(``Public L''). All of the stock of P is owned by 150,000 shareholders, 
none of whom own as much as five percent of P stock (``Public P''). 
Between July 12, 1988 and August 13, 1988, P purchases all of the L 
stock through a series of transactions on the public stock exchange. P's 
percentage of direct stock ownership in L increases from 4.9 percent to 
five percent on July 15, 1988, and from 50 percent to 51 percent on July 
30, 1988.
    (ii) Before July 15, 1988, P is a public shareholder of L. On and 
after July 15, 1988, P is a first tier entity (and a highest tier 
entity) of L. Accordingly, under the rules of paragraph (j)(1) of this 
section, Public P, on and after July 15, 1988, is treated as a public 
group that is a 5-percent shareholder. Each acquisition by P on and 
after such date affects the percentage of L stock that is owned by 
Public P and thus constitutes an owner shift.
    (iii) Immediately after the transaction on July 30, 1988, P owns 51 
percent of L stock. Under paragraph (j)(1)(iv)(A) of this section, 
Public P thus owns 51 percent of L. Under paragraph (j)(1)(iv)(C) of 
this section, Public L, the public group that includes the public 
shareholders of L, is treated as a 5-percent shareholder that owns 49 
percent of L. Under paragraph (j)(1)(iii) of this section, Public L and 
Public P are presumed not to have any common members and it is also 
presumed that no member of either public group is related to any other 
member of either of the two public groups.
    (iv) Assuming that the presumption provided in paragraph (j)(1)(iii) 
of this section (i.e., that no person owns stock in both P and L) is not 
rebutted to any extent, Public P is treated as a 5-percent shareholder 
whose stock ownership in L, as of the July 30, 1988 testing date, has 
increased by 51 percentage points over its lowest percentage of stock 
ownership in L at any time during the testing period (0 percent prior to 
July 12, 1988). Accordingly, an ownership change with respect to L 
occurs as a result of P's acquisition on July 30, 1988. L is thus a new 
loss corporation and its pre-change losses are subject to limitation 
under section 382.
    Example (2) (i) All of the stock of P is owned by 1,000 unrelated 
shareholders, none of whom owns as much as five percent of P stock. 
L1 is a wholly owned subsidiary of P. On January 2, 1988, P 
distributes all of the L1 stock pro rata to its shareholders.
    (ii) Prior to the stock distribution, the public owners of P are 
members of a public group (``Public P'') that is treated as a 5-percent 
shareholder owning 100 percent of the stock of L1.
    See paragraph (j)(1)(iv)(A) of this section. Following the stock 
distribution to the P shareholders, L1 is owned by 1,000 
public

[[Page 474]]

shareholders that are members of a public group (``Public 
L1'') that is treated as a 5-percent shareholder owning 100 
percent of the stock of L1. See paragraph (j)(1)(iv)(C) of 
this section.
    (iii) Public P and Public L1 are treated as unrelated, 
individual 5-percent shareholders under paragraph (j)(1)(iii) of this 
section. Although the members of one public group are presumed not to be 
members of any other public group under paragraph (j)(1)(iii) of this 
section, L1 has actual knowledge that all of its public 
shareholders immediately following the distribution (Public 
L1) received L1 stock pro rata in respect to the 
outstanding P stock and thus were also members of Public P. Applying 
paragraph (k)(2) of this section, the loss corporation may take into 
account the identity of ownership interests between Public L1 
and Public P to establish that Public L1 did not increase its 
percentage ownership in L1. Accordingly, the transaction 
would not constitute an owner shift.
    Example (3) (i) The facts are the same as in Example (1) of 
paragraph (g)(4) of this section. Thus, 20 percent of L stock is owned 
by A, 10 percent is owned by P1, 20 percent is owned by E, a 
joint venture, and the remaining 50 percent of L stock is owned by 
Public L. P1 is owned 15 percent by B and 85 percent by 
Public P1. E is owned 30 percent by P2 and 70 
percent by P3, which are owned by Public P2 and 
Public P3, respectively. See Example (1)(ii) of paragraph 
(g)(4) of this section for a chart illustrating this ownership 
structure.
    (ii) The public owners of P2 and P3 (Public 
P2 and Public P3, respectively), are public groups 
that are treated as 5-percent shareholders of L, because each such 
public group indirectly owns five percent or more of L stock (six 
percent by Public P2 [(30 percent ownership of E)x(20 percent 
ownership of L)] and 14 percent by Public P3 [(70 percent 
ownership of E)x(20 percent ownership of L)]). The public owners of 
P1 (``Public P1''), who indirectly own 8.5 percent 
of L stock [(85 percent ownership of P1)x(10 percent 
ownership of L)] and B, who indirectly owns 1.5 percent of L and is thus 
included in Public P1 under paragraph (j)(1)(iv)(A) of this 
section, are members of a public group that is treated as a 5-percent 
shareholder of L that owns ten percent of L stock. Finally, the public 
group of L (``Public L'') is a 5-percent shareholder that owns 50 
percent of L. Accordingly, A, Public L, Public P1 (including 
B), Public P2, and Public P3 are the only 5-
percent shareholders of L.
    Example (4) (i) The facts are the same as Example (3) above, except 
that P3 is owned 60 percent by C, 30 percent by 
P4, and 10 percent by P3. The stock of 
P4 is publicly traded and is owned by Public P4. 
The facts are thus the same as in Example (2) in paragraph (g)(4) of 
this section. See Example (2)(ii) of paragraph (g)(4) of this section 
for a chart illustrating this ownership structure.
    (ii) The public owners of P4 (a highest tier entity) are 
members of a public group that indirectly owns 4.2 percent of L ([30 
percent ownership of P3]x[70 percent ownership of E]x[20 
percent ownership of L]). For purposes of identifying public groups that 
are 5-.percent shareholders, L is not required to identify P4 
as a highest tier entity under paragraph (k)(3) of this section because 
P4 does not own five percent or more of L stock. Moreover, 
under paragraph (h)(2)(iii) of this section, P4 generally is 
treated as an individual from which there is no attribution of loss 
corporation stock. The public group of P3 (including 
P4) indirectly owns 5.6 percent of L ([40 percent of 
P3]x[70 percent ownership of E]x[20 percent of L]), and is 
thus a 5-percent shareholder of L. The public groups of P2 
and P1 (both Public P1 and B), respectively, also 
own five percent or more of L stock and are thus 5-percent shareholders 
of L. In addition, the public group of L is a 5-percent shareholder 
regardless of whether it owns five percent of L stock. Accordingly, A, 
Public L, Public P3 (including P4), Public 
P2, and Public P1 (including B), are the only 5-
percent shareholders of L.
    Example (5)(i) On September 4, 1987, L is owned 14 percent by each 
of A and B, 30 percent by each of P1 and P2, four 
percent by each of C and P3, and two percent by each of D and 
AA. P1 is owned 30 percent by each of A, B, and P4 
and 10 percent by D. P2 is owned 70 percent by A, 10 percent 
by each of B and D, six percent by DD and four percent by C. AA owns 100 
percent of the stock of P3. P4 is owned 60 percent 
by C and 20 percent by each of BB and CC.
    (ii) The ownership structure of L is illustrated by the following 
chart:

    (iii) In order to identify L's 5-percent shareholders and their 
respective ownership interests in L on September 4, 1987, the rules of 
paragraph (j)(1) of this section apply to identify the public groups 
that are treated as separate 5-percent shareholders. Analysis begins 
with any highest tier entity, such as P4. Each of 
P4's shareholders is a 5-percent owner of P4. 
C4 owns 5.4 percent of L in his capacity as a 5-percent owner 
of P4 and therefore is a 5-percent shareholder. 
Notwithstanding that C actually owns, directly and by attribution, 10.6 
percent of L (four percent directly, 5.4 percent indirectly through 
P4, and 1.2 percent through P2), C's ownership 
interest in L as a 5-percent shareholder is presumed to include only the 
5.4 percent indirect ownership through P4. (Under paragraphs 
(g) and (k)(2) of this section, however, L must account for C's direct 
and indirect ownership interests in determining whether an ownership 
change occurs on any testing date if it has actual knowledge of such 
ownership on or berfore the date that its income tax return is filed for 
the taxable year that includes the testing date). Although BB and CC are 
each 5-percent owners of P4, they are not 5-percent 
shareholders and therefore are members of the public group of 
P4. Because the public group of P4 indirectly owns 
only 3.6 percent of L, it is treated under paragraph (j)(1)(iv)(A) of 
this section as part of the public group of the next lower tier entity, 
P1.
    (iv) With respect to P1, a first tier entity, each of its 
shareholders are 5-percent owners. Because A and B each indirectly own 
nine percent of L as 5-percent owners of P1 and A indirectly 
owns 21 percent of L as a 5-percent owner of P2, they are 
each 5-percent shareholders without regard to their direct

[[Page 476]]

ownership interests in L. A's ownership interest in L as a 5-percent 
shareholder is 44 percent (14 percent directly, nine percent in his 
capacity as a 5-percent owner of P1, and 21 percent in his 
capacity as a 5-percent owner of P2). B's ownership interest 
in L as a 5-percent shareholder is 23 percent (14 percent directly and 
nine percent in his capacity as a 5-percent and nine percent in his 
capacity as a 5-percent owner of P1). B's ownership interest 
as a 5-percent shareholder does not include the three percent interest 
he owns indirectly through P2. (Under paragraphs (g) and 
(k)(2) of this section, however, L must account for B's direct and 
indirect ownership interests, including his three percent interest 
through P2, in determining whether an ownership change occurs 
on any testing date if L has actual knowledge of such ownership on or 
before the date that its income tax return is filed for the taxable year 
that includes the testing date.) D is a 5-percent owner of 
P1. Although D owns eight percent of L (two percent directly, 
three percent indirectly through P1, and three percent 
indirectly through P2), he is not a 5-percent shareholder 
because he does not own five percent or more of L stock either directly 
or in his capacity as a 5-percent owner of either P1 or 
P2. (Under paragraphs (g) and (k)(2) of this section, 
however, L must account for D's direct and indirect ownership interests 
in determining whether an ownership change occurs on any testing date to 
the extent L has actual knowledge of such ownership amounting to five 
percent or more of L stock before the date that its income tax return is 
filed for the taxable year that includes the testing date.) The public 
group of P1 (comprised of the public group of P4 
and D's direct ownership interest in P1) has a 6.6 percent 
interest in L and is therefore treated as a separate 5-percent 
shareholder.
    (v) With respect to highest tier entity P2, D is a 5-
percent owner who is not a 5-percent shareholder for the reason 
described in the preceding subdivision. DD is a 5-percent owner of 
P2, who is not a 5-percent shareholder, because DD indirectly 
owns only 1.8 percent of L. Assuming that L does not have actual 
knowledge of B's and C's direct ownership interest in P2, 
those interests are accounted for in computing the ownership interest 
are accounted for in computing the ownership interest of the public 
group of P2. Therefore, each of P2's shareholders, 
except A who is a 5-percent shareholder in his capacity as a 5-percent 
owner of P2, are treated as members of the public group of 
P2 that owns nine percent of L and is thus treated as a 
separate 5-percent shareholder.
    (vi) Because the direct ownership interest of P3 is less 
than five percent, it is a public shareholder. Therefore, assuming that 
L does not have actual knowledge of C's, D's, or AA's direct and/or 
indirect ownership interests in L, the public group of L is a separate 
5-percent shareholder owning 12 percent of L (comprised of the direct 
ownership interests of C, D, AA and P3).

    (2) Segregation rules applicable to transactions involving the loss 
corporation--(i) In general. For purposes of this section, if--
    (A) A transaction is described in paragraph (j)(2)(iii) of this 
section, and
    (B) The loss corporation has one or more direct public groups 
immediately before and after the transaction,


the stock owned by such direct public group or groups is subject to the 
segregation rules described in paragraph (j)(2)(iii) of this section for 
purposes of determining whether an ownership change has occurred on the 
date of the transaction (and on any subsequent testing date with a 
testing period that includes the date of such transaction). See 
paragraph (j)(3) of this section for the application of the rules of 
this paragraph (j)(2) to transactions involving first tier entities or 
higher tier entities.
    (ii) Direct public group. For purposes of this section, a direct 
public group is any public group of the loss corporation described in 
paragraph (j)(1)(iv)(C) of this section or any public group of the loss 
corporation resulting from the application of paragraph (j)(2)(iii) or 
(j)(3)(i) of this section.
    (iii) Transactions to which segregation rules apply--(A) In general. 
The segregation rules of this paragraph (j)(2)(iii) apply to any 
transaction described in paragraph (j)(2)(iii)(B), (C), (D), (E), or (F) 
of this section in the manner specified. The presumptions adopted by 
this paragraph (j)(2)(iii) shall not apply only if, and to the extent 
that, the loss corporation either has actual knowledge of facts to the 
contrary regarding its stock ownership and is thus subject to paragraph 
(k)(2) of this section, or is subject to paragraph (k)(4) of this 
section. Any direct public group that is required to be identified as a 
result of a transaction described in paragraph (j)(2)(iii) of this 
section shall be treated as a 5-percent shareholder under paragraph 
(g)(1)(iv) of this section without regard to whether such group, at any 
time during the testing period, owns five percent or more of the loss 
corporation stock. To the extent that the presumptions are rebutted, the 
public

[[Page 477]]

shareholders, public owners and 5-percent owners who are not 5-percent 
shareholders may be aggregated into additional public groups. For an 
exception applicable to certain regulated investment companies, see 
Sec. 1.382-3(k)(1).
    (B) Certain equity structure shifts and transactions to which 
section 1032 applies--(1) In general. In the case of--
    (i) A transaction that is an equity structure shift that also is 
described in section 381(a)(2) and in which the loss corporation is a 
party to the reorganization, or
    (ii) A transfer of the stock of the loss corporation (including 
treasury stock) by the loss corporation in any other transaction to 
which section 1032 applies,

each direct public group that exists immediately after such transaction 
shall be segregated so that each direct public group that existed 
immediately before the transaction is treated separately from the direct 
public group that acquires stock of the loss corporation in the 
transaction. The direct public group that acquires stock of the loss 
corporation in the transaction is presumed not to include any members of 
any direct public group that existed immediately before the transaction. 
For purposes of this paragraph (j)(2)(iii)(B), a person is treated as 
acquiring stock of the loss corporation in a reorganization as the 
result of the person's ownership interest in another corporation that 
succeeds to the loss corporation's pre-change losses (determined as if 
the testing date were the change date and treating the amount of any net 
unrealized built-in loss as a pre-change loss) in a transaction to which 
section 381(a)(2) applies. In determining whether a transaction is 
described in section 1032 for purposes of this paragraph (j)(2)(iii)(B), 
the transfer by the loss corporation of any interest not constituting 
stock that is treated as stock under paragraph (f)(18)(iii) of this 
section shall be treated as the transfer of stock. See Sec. 1.382-3(j) 
for exceptions to the segregation rules of this paragraph 
(j)(2)(iii)(B)(1).
    (2) Examples.

    Example (1) (i) P1 owns 60 percent of the stock of L. The 
remaining L stock (40 percent) is owned by Public L. A owns 40 percent 
of the P1 stock. The remaining P1 stock (60 
percent) is owned by Public P1. P2 is a publicly 
traded corporation owned by shareholders who each own less than five 
percent of P2 stock (Public P2).
    (ii) On May 22, 1988, L merges into P2 in a transaction 
described in section 368(a)(1)(A), with the shareholders of L receiving 
an amount of P2 stock equal to 70 percent of the value of 
P2 immediately after the reorganization.
    (iii) Immediately before the merger, L's 5-percent shareholders were 
Public L (40 percent), Public P1 (36 percent), and A (24 
percent). Although the shareholders of P2 (immediately before 
the merger) do not acquire any stock in the merger, they are treated as 
acquiring a direct ownership interest in the loss corporation in the 
reorganization because P2 succeeds to the pre-change losses 
of L in a transaction to which section 381(a)(2) applies. As a result of 
the merger, which constitutes a transaction described in 
(j)(2)(iii)(B)(1) of this section, L's direct public group, Public L, 
must be segregated from the direct public group that would otherwise 
exist after the transaction (Public L and Public P2). Public 
L, the direct public group that exists before the merger, has a 
continuing 28 percent interest in the loss corporation [70 percent of 
P2 shares received in the merger x 40 percent shares of L 
owned prior to the merger] that must be segregated from the interests 
acquired by Public P2.
    (iv) In addition, Public P1, which owns five percent or 
more of the stock of P2 through P1's ownership 
interest in P2, also is segregated from any other public 
group (i.e., both Public L and Public P2) under paragraph 
(j)(1) of this section. Therefore, under paragraphs (j)(1) and (2) of 
this section, Public P2 (excluding the members of Public L 
and Public P1 immediately before the merger) is treated as a 
separate public group and 5-percent shareholder.
    (v) The only 5-percent shareholder whose interest in the loss 
corporation, P2, has increased during the testing period is 
Public P2. Its interest has increased by 30 percentage 
points. Accordingly, no ownership change results from the merger. For 
purposes of measuring the shift in ownership of P2 on any 
subsequent testing date with a testing period that includes May 22, 1988 
(the date on which L merged into P2), Public P2 
will continue to be treated as a direct public group, separate from 
Public L (the members of which own P2 stock as a result of 
the merger) and Public P1.
    Example (2) (i) P and L are each owned by 21 equal shareholders. 
Each of 14 of the shareholders of P and L are owners of both 
corporations (``common owners''). L has actual knowledge of this cross 
ownership. therefore, as a group, these persons own 66\2/3\ percent of 
each of P and L. P stock has a value of $600 and L stock has a value of 
$400.

[[Page 478]]

    (ii) P merges into L under section 368(a)(1)(A) on June 10, 1988. 
Ordinarily, the direct public group of L that exists immediately before 
the transaction would be segregated from the direct public group that 
acquires stock in the merger (the public group of P immediately before 
the merger). In view of the common ownership of P and L, however, a 
third group may be created under paragraph (j)(2)(iii)(A) of this 
section so that L's owners following the merger would be: The common 
owners (66\2/3\ percent), Public L, less the common owners, 13\1/3\ 
percent), and Public P, less the common owners (20 percent). 
Accordingly, the only 5-percent shareholder increasing its ownership 
interest by 20 percentage points and no ownership change occurs as a 
result of the merger.
    Example (3) (i) L is entirely owned by Public L. L commences and 
completes a public offering of common stock on January 22, 1988, with 
the result that its outstanding stock increases from 100,000 shares to 
300,000 shares. No person owns as much as five percent of L stock 
following the public offering.
    (ii) The public offering of L stock is a transaction to which 
section 1032 applies. Immediately before the public offering, L's only 
5-percent shareholder was Public L, a direct public group. Therefore, 
Public L (as in existence immediately before the transaction) must be 
segregated from the direct public group that would otherwise exist 
immediately after the transaction. Under paragraph (j)(2)(iii)(B)(1) of 
this section, the acquisition of 200,000 shares of L stock in the public 
offering must be treated as acquired by a direct public group (``New 
Public L'') that is separate from Public L. Each such public group is 
treated as an individual that is a separate 5-percent shareholder. See 
paragraphs (g)(1)(iv) and (j)(1)(ii) of this section.
    (iii) As a result of the public offering, L has two 5-percent 
shareholders, Public L and New Public L, which own 33\1/3\ percent and 
66\2/3\ percent of the stock of L, respectively. Because the members of 
New Public L are presumed not to be members of Public L (and not to be 
related to any such members), the ownership interest of New Public L 
immediately prior to the offering of stock was 0 percent.
    (iv) New Public L is a 5-percent shareholder that has increased its 
ownership interest in L by more than 50 percentage points during the 
testing period (by 66\2/3\ percentage points). Thus, there is an 
ownership change with respect to L. For purposes of subsequent 
transactions, Public L and New Public L will not be segregated into two 
public groups because a new testing period commences on the day 
following the change date, January 23, 1988 (i.e., any subsequent 
testing date will not have a testing period that includes the date of 
the public offering).
    Example (4) The facts are the same as in Example (3), but L 
establishes that 60,000 shares of the newly issued L stock were acquired 
by its shareholders of record on the date of the stock issuance (i.e., 
members of Public L, referred to as Acquiring Public L) by persons 
owning 27 percent of the L stock immediately before the stock issuance. 
Accordingly, L has actual knowledge that New Public L acquired no more 
than 140,000 shares of L stock in the public offering. Under paragraphs 
(j)(2)(iii) and (k)(2) of this section, New Public L may be treated as 
having increased its ownership interest in L by 46\2/3\ percentage 
points (140,000 shares acquired in the offering/300,000 shares 
outstanding). L also has actual knowledge that the members of Public L 
owning 27 percent of L stock immediately before the stock issuance 
(27,000 shares/100,000 shares outstanding) own 29 percent of L stock 
immediately after such issuance ([27,000 shares + 60,000 shares acquired 
in the offering]/300,000 shares outstanding). Assuming that L chooses to 
take its actual knowledge into account for purposes of determining 
whether an ownership change occurred on January 22, 1988, Public L is 
segregated into two direct public groups immediately before the stock 
issuance so that the two percentage point increase in the ownership 
interest in L by Acquiring Public L is taken into account. The total 
increased ownership interest in L by New Public L and Acquiring Public L 
on the testing date over their lowest ownership interest during the 
testing period is 48 2/3 percent. Thus, no ownership change occurs with 
respect to L.
    Example (5) (i) L is owned entirely by 10,000 unrelated individuals, 
none of whom own as much as five percent of L stock (``Public L''). P is 
owned entirely by 1,500 unrelated individuals, none of whom own as much 
as five percent of P stock (``Public P''). On December 22, 1988, L 
acquires all of the P stock from Public P in exchange for L stock 
representing 25 percent of the value of L, in a transaction described in 
section 368(a)(1)(B).
    (ii) Under paragraph (j)(2)(iii)(B)(1) of this section, Public L, 
the direct public group that owns L stock immediately before and after 
the transaction to which section 1032 applies, is treated separately 
from Public P, the direct public group that acquires L stock in the 
transaction. Because Public P's percentage ownership interest in L 
increases to only 25 percent (as compared with 0 percent before the 
acquisition), no ownership change occurs. For purposes of determining 
whether an ownership change occurs on any testing date with a testing 
period that includes December 22, 1988, Public L and Public P will 
continue to be treated as separate 5-percent shareholders.
    (iii) See Example (4) in paragraph (j)(3)(iv) of this section for 
the application of paragraph (j)(2)(iii)(B) of this section to a 
reorganization under section 368(a)(1)(B) in which the loss corporation 
is acquired.


[[Page 479]]


    (C) Redemption-type transactions--(1) In general. In the case of a 
transaction in which the loss corporation acquires its stock in exchange 
for property, each direct public group that exists immediately before 
the transaction shall be segregated at that time (and thereafter) so 
that the stock that is acquired in the transaction is treated as owned 
by a separate public group from each public group that owns the stock 
that is not acquired. For purposes of the preceding sentence, the term 
property shall include stock described in section 1504(a)(4) and stock 
described in paragraph (f)(18)(ii) of this section. Each direct public 
group that owned the stock that is acquired in the transaction is 
presumed not to own any such stock immediately after the transaction.

    (2) Examples.

    Example (1). L is entirely owned by Public L. There are 500,000 
shares of L stock outstanding. On July 12, 1988, L acquires 150,000 
shares of its stock for cash. Because L's acquisition is a redemption, 
Public L is segregated into two different public groups immediately 
before the transaction (and thereafter) so that the redeemed interests 
(``Public RL'') are treated as part of a public group that is separate 
from the ownership interests that are not redeemed (``Public CL''). 
Therefore, as a result of the redemption, Public CL's interest in L 
increases by 30 percentage points (from 70 percent (350,000/500,000) to 
100 percent) on the July 12, 1988 testing date. Because the resulting 
increase is not more than 50 percentage points, no ownership change 
occurs. For purposes of determining whether an ownership change occurs 
on any subsequent testing date having a testing period that includes 
such redemption, Public CL is treated as a 5-percent shareholder whose 
percentage ownership interests in L increased by 30 percentage points as 
a result of the redemption.
    Example (2). L is entirely owned by Public L. There are 250,000 
shares of L common stock outstanding. On April 22, 1988, L acquires 
100,000 shares of its outstanding common stock in exchange for 100,000 
shares of preferred stock described in section 1504(a)(4). (The 
transaction thus constitutes a recapitalization within the meaning of 
section 368(a)(1)(E).) As a result of the recapitalization, which is a 
transaction described in paragraph (j)(2)(iii)(C) of this section, 
Public L is segregated into two different public groups immediately 
before the transaction (and thereafter) so that the stock acquired by L 
is treated as owned by a public group (``Public RL'') that is separate 
from the public group that owns the stock that is not so acquired 
(``Public CL''). Therefore, as a result of the transaction, Public CL's 
interest in L increases by 40 percentage points (from 60 percent to 100 
percent). Because the resulting increase is not more than 50 percentage 
points, no ownership change occurs. For purposes of determining whether 
an ownership change occurs on any subsequent testing date with a testing 
period that includes the date of the recapitalization, Public CL is 
treated as a separate 5-percent shareholder whose percentage ownership 
interest increased by 40 percentage points as a result of the redemption 
type transaction.

    (D) Acquisition of loss corporation stock as the result of the 
ownership of a right to acquire stock--(1) In general. In the case of a 
deemed acquisition of stock of the loss corporation as the result of the 
ownership of a right issued by the loss corporation to acquire such 
stock (see paragraph (h)(4) of this section), each direct public group 
that exists immediately after such acquisition shall be segregated so 
that each direct public group that existed immediately before the 
transaction is treated separately from the direct public group that is 
deemed to acquire stock of the loss corporation as a result of the 
ownership of the right to acquire such stock. The direct public group 
that is treated as acquiring stock of the loss corporation in the 
transaction is presumed not to include any members of any direct public 
group that existed immediately before the transaction. In applying the 
rules of paragraph (h)(4) of this section, the segregation rules of this 
paragraph (j)(2)(iii)(D) shall apply before making the determination 
required under that paragraph (h)(4) of this section. See Sec. 1.382-
3(j)(9) for rules relating to this paragraph (j)(2)(iii)(D).
    (2) Example.

    (i) L has 700,000 shares of common stock outstanding. Public L owns 
all of the outstanding L common stock. On May 20, 1988, L issues a class 
of debentures to the public that, in the aggregate, may be converted 
into 300,000 shares of L common stock. On September 7, 1988, 
P1 acquires 210,000 shares of L common stock over a public 
stock exchange. None of the L debentures have been converted as of that 
date.
    (ii) By virtue of L's issuance of convertible debentures, May 20, 
1988 is a testing date. See paragraph (a)(2)(i) of this section. 
Immediately before the issuance of the convertible debentures, L's only 
5-percent shareholder

[[Page 480]]

was Public L, a direct public group. Therefore, under paragraph 
(j)(2)(iii)(D) of this section, Public L must be segregated from the 
direct public group that would otherwise exist immediately after the 
transaction for the purpose of applying paragraph (h)(4) of this 
section, so that any acquisition of L stock through the conversion of 
L's debentures is treated as made by a public group other than Public L 
(``New Public L''). Assuming the largest increase in the total 
percentage stock ownership of New Public L on the testing date (see 
paragraph (h)(4) of this section), New Public L would have increased its 
ownership interest in L by 30 percentage points. Therefore, the stock of 
L would not be treated as acquired pursuant to a deemed conversion of 
the L debentures on May 20, 1988, under paragraph (h)(4) of this 
section, because the conversion would not cause an ownership change.
    (iii) P1's acquisition of L common stock results in 
second testing date. For the purpose of applying paragraph (h)(4) of 
this section, Public L must again be segregated from the direct public 
group that would otherwise result from conversion of the debentures, so 
that a deemed acquisition of L stock through the conversion of L's 
debentures on September 7, 1988 is treated as made by a public group 
other than Public L (``New Public L''). As on the previous testing date, 
New Public L would have increased its ownership interest in L by 30 
percentage points if it were treated as having acquired L common stock 
pursuant to the conversion of the L debentures. The increase in New 
Public L's ownership, taken together with P1's 21 percentage 
point ownership increase in L during the testing period [210,000 shares 
deemed converted/(700,000 (actual) + 300,000 (deemed) shares 
outstanding)], results in an ownership change.

    (E) Transactions identified in the Internal Revenue Bulletin. Any 
transaction that is designated by the International Revenue Service in 
the Internal Revenue Bulletin shall be subject to the rules, as provided 
in such bulletin, similar to the rules described in this paragraph 
(j)(2)(iii).
    (F) Issuance of rights to acquire loss corporation stock--(1) In 
general. In the case of any transaction that is described in paragraph 
(j)(2)(iii)(B), (D) or (E) of this section in which the loss corporation 
issues rights to acquire its stock to the members of more than one 
public group, those rights shall be presumed to be exercised pro rata by 
each such public group as those rights are actually exercised. See Sec. 
1.382-3(j)(10) for an exception to the application of the rule of this 
paragraph (j)(2)(iii)(F)(1) to stock issued on the exercise of a 
transferable option.
    (2) Example.

    (i) L, which has six million shares outstanding, is owned entirely 
by Public L and P is owned entirely by Public P. On November 30, 1988, P 
merges into L in a transaction qualifying under section 368(a)(1)(A) 
with Public P receiving four million shares of L stock as a result of 
the reorganization. Under paragraph (j)(2)(iii)(B) of this section, 
Public L and Public P continue to be treated as separate public groups 
following the merger. Pursuant to the plan of reorganization, L also 
issues an amount of warrants in L stock pro rata to Public L and Public 
P that, if exercised, would result in the issuance of an additional two 
million shares of L stock. On November 30, 1989, when only one-half of 
the outstanding warrants have been exercised, A acquires all of the 
unexercised warrants.
    (ii) Without regard to the warrants distributed in reorganization, 
Public P's ownership interest in L increases by 40 percentage points on 
November 30, 1988, relative to its lowest ownership interest in L at any 
time during the testing period (0 percent prior to the merger). For 
purposes of determining whether an ownership change occurs on November 
30, 1988, the segregation rules of paragraphs (j)(2)(iii)(B) and (D) of 
this section does not require that a third direct public group be 
separately identified and treated as acquiring the warrants, because L 
has actual knowledge that Public L and Public P acquired the distributed 
warrants in proportion to their respective ownership interests in L 
stock. Because the largest increase in the ownership of L on the testing 
date results from treating only Public P as exercising the distributing 
warrants, in which event, its ownership interest would increase by 44.4 
percentage points ([four million shares acquired in the merger + 800,000 
shares deemed acquired]/10.8 million (actual and deemed) shares 
outstanding), the issuance of the warrants by L does not cause an 
ownership change on November 30, 1988.
    (iii) Under paragraph (j)(2)(iii)(F)(1) of this section, each actual 
exercise of warrants to acquire one million shares of L stock between 
November 30, 1988 and November 30, 1989 is treated as made pro rata by 
Public L and Public P (600,000 shares to Public L and 400,000 shares to 
Public P). Accordingly, as a result of the actual exercises of warrants 
during that period the ownership interests of the only 5-percent 
shareholders, Public L and Public P, are proportionately increased.
    (iv) A's acquisition of the all of the outstanding warrants on 
November 30, 1989 requires the determination whether there has been an 
ownership change with respect to L, because A would be 5-percent 
shareholder

[[Page 481]]

under paragraph (g)(1)(i) of this section owning 8\1/3\ percent of the L 
stock if the acquired warrants were exercised (one million shares deemed 
acquired/12 million (actual and deemed) shares outstanding). See 
paragraph (a)(2)(i) of this section. Under paragraph (h)(4)(i) of this 
section, A is not treated as having exercised those warrants, because an 
ownership change would not results. (Public P's 36\2/3\ percentage point 
increase [(four million shares acquired in the merger + 400,000 shares 
deemed acquired)/12 million (actual and deemed) shares outstanding] and 
A's 8\1/3\ percentage point increase is not greater than 50 percentage 
points).

    (iv) Combination of de minimis public groups--(A) In general. 
Notwithstanding paragraph (j)(2)(iii)(A) of this section, any public 
group first identified during a taxable year, as a result of any 
transaction described in paragraph (j)(2)(iii)(B), (D), (E), or (F) of 
this section, that owns less than five percent of loss corporation stock 
may be combined, at the option of the loss corporation, with any other 
such groups also first identified as a result of any such transaction 
that occurs during such taxable year.
    (B) Example.

    (i) L is widely held with no person owning as much as five percent 
of the L stock at any time (``Public L''). L's taxable year ends on 
December 31. On January 1, 1989, L issues a class of debt maturing on 
December 31, 2019 (``Class A Debentures'') with respect to which it will 
semi-annually issue L stock in discharge of its interest obligation. In 
addition, L issues an amount of L stock to the public in two separate 
transactions during 1989. As a percentage of the L stock outstanding at 
the close of L's taxable year on December 31, 1989, L issued .45 percent 
of its stock on each of two dates in payment of interest with respect to 
the Class A Debentures, 4.5 percent of its stock in the first stock 
offering and six percent of its stock in the second stock offering. 
During 1990, L did not issue stock other than in payment of interest 
with respect to the Class A Debentures. As a percentage of L stock 
outstanding on December 31, 1990, L issued .41 percent of its stock on 
each of two dates during 1990 with respect to its outstanding debt.
    (ii) Under paragraph (h)(4)(x)(E) of this section, L's obligation to 
issue stock in satisfaction of the interest with respect to the Class A 
Debentures until December 31, 2019, is not subject to paragraph 
(h)(4)(i) of this section and thus is taken into account only as such 
stock is issued.
    (iii) The application of the segregation rules of paragraphs 
(j)(2)(iii)(B) and (iv) of this section require the identification of at 
least two additional, separate direct public groups during 1989. First, 
the persons who acquire six percent of L stock in a public offering to 
which section 1032 applies must be treated as a separate 5-percent 
shareholder (``Public 1L''). See paragraph (j)(2)(iii)(B) of this 
section. Even though this group was first identified in 1989, it may not 
be combined with other public groups also first identified in 1989 
because it owns five percent or more of L stock. Second, although each 
of the three other issuances of L stock during the year ordinarily 
result in the identification of an additional, separate direct public 
group, each such direct public group may be combined with the two other 
such groups into a single public group (``Public 2L''). As of the end of 
1989, Public 2L would own a total of 5.4 percent of the stock of L.
    (iv) The application of the segregation rules of paragraphs 
(j)(2)(iii)(B) and (iv) of this section require the identification of at 
least one additional, direct public group during 1990. Because each 
additional, direct public group first identified in 1990 acquires less 
than five percent of L stock, they may be combined into a single public 
group (``Public 3L'') owning .82 percent of the stock of L. Public 3L is 
treated as a five percent shareholder even though it owns less than five 
percent of the stock of L. See paragraph (j)(2)(iv)(A) of this section.

    (v) Multiple transactions--(A) In general. If a transaction (or any 
part thereof) is described by more than one subdivision of paragraph 
(j)(2)(iii) of this section, each such subdivision shall apply to the 
transaction (or each part of the transaction) in the manner that results 
in the largest increase in the percentage stock ownership by the 5-
percent shareholders.
    (B) Example.

    (i) All of the common stock of L is owned by 1,000 unrelated 
persons, none of whom owns as much as five percent of the L stock 
(``Public CL''). L has outstanding a class of preferred stock described 
in section 1504(a)(4) that is owned in equal amounts by 500 unrelated 
persons (``Public PL'').
    (ii) On September 4, 1988, L rearranges its capital structure by 
redeeming 70 percent of the common stock owned by 700 of the 
shareholders in exchange for cash. In addition, all of the preferred 
stock is exchanged for a new class of common stock (nonvoting) 
representing 40 percent of the value of L.
    (iii) With respect to the part of the transaction that is treated as 
a redemption under paragraph (j)(2)(iii)(C) of this section (the 
exchange of common stock for cash), Public CL is segregated into two 
different public groups immediately before the transaction (and

[[Page 482]]

thereafter) so that the owners of the redeemed stock (``Public RCL'') 
are treated as part of a public group that is separate from the public 
group comprised of the owners of the stock that is not redeemed 
(``Public CCL''). As a result of the redemption, Public CCL's percentage 
ownership interest in L thus increases by 30 percentage points from 30 
percent to 60 percent (taking into account all transactions occurring on 
the testing date, because the change in ownership is measured under 
paragraph (a)(1)(i) of this section by reference to each 5-percent 
shareholder's ownership interest immediately after the testing date). In 
addition, the exchange of preferred stock for nonvoting common stock is 
a transaction to which section 1032 applies. Under paragraph (j)(2)(v) 
of this section, the part of the transaction to which section 1032 
applies is also subject to the segregation rules in the manner specified 
in paragraph (j)(2)(iii)(B) of this section. Accordingly, Public PL, the 
direct public group that acquires L nonvoting common stock in exchange 
for L preferred stock, must be treated as a separate public group from 
the other direct public groups, Public CCL and Public RCL. As a separate 
public group, Public PL's percentage stock ownership in L increases by 
40 points (as compared to 0 percent prior to the transaction).
    (iv) In summary, Public CCL increases its percentage ownership in L 
by 30 percentage points and Public PL increases its percentage ownership 
by 40 percentage points. Consequently, an ownership change occurs with 
respect to L on September 4, 1988.

    (vi) Acquisitions made by either a 5-percent shareholder or the loss 
corporation following application of the segregation rules. Unless a 
different proportion is established by either the loss corporation or 
the Internal Revenue Service, the acquisition of loss corporation stock 
by either a 5-percent shareholder or the loss corporation on any date on 
which more than one public group of the loss corporation exists by 
virtue of the application of the rules of this paragraph (j)(2) shall be 
treated as being made proportionately from each public group existing 
immediately before such acquisition. See paragraph (g)(5)(i)(B) of this 
section for the application of this paragraph to the ownership interest 
of a 5-percent shareholder that owns less than five percent of the stock 
of the loss corporation on the testing date.
    (3) Segregation rules applicable to transactions involving first 
tier entities or higher tier entities--(i) Dispositions. If a loss 
corporation is owned, in whole or in part, by a public group (or 
groups), the rules of paragraphs (j)(2)(iii)(B) and (iv) of this section 
shall apply to any transaction in which a first tier entity or an 
individual that owns a direct ownership interest in the loss corporation 
of five percent or more transfers a direct ownership interest in the 
loss corporation to public shareholders. Therefore, each direct public 
group that exists immediately after such a disposition shall be 
segregated so that the ownership interests of each public group that 
existed immediately before the transaction are treated separately from 
the public group that acquires stock of the loss corporation as a result 
of the disposition by the individual or first tier entity. The 
principles of this paragraph (j)(3)(i) shall also apply to transactions 
in which an ownership interest in a higher tier entity that owns five 
percent or more of the loss corporation (determined without regard to 
the application of paragraph (h)(2)(i)(A) of this section) or a first 
tier entity is transferred to a public owner or 5-percent owner who is 
not a 5-percent shareholder.
    (ii) Example.

    (A) L is owned equally by Public L, P and E. Public L consists of 
150 equal, unrelated shareholders. P is owned by Public P, a group 
consisting of 1,500 equal, unrelated shareholders. E is a partnership 
and none of its partners are 5-percent owners. On October 22, 1988, E 
sells its entire interest in L over a public stock exchange. No 
individual or entity acquires as much as five percent of L's stock as 
the result of E's disposition of the L stock.
    (B) The disposition of the L stock by E is a transaction that causes 
the segregation of L's direct public group that exists immediately 
before the transaction (Public L) from the direct public group that 
acquires L stock in the transaction (Public EL). As a result, L has 
three 5-percent shareholders, Public L, Public P (through the 
application of paragraph (j)(1) of this section) and Public EL, each of 
which owns 33\1/3\ percent of L stock. Therefore, Public EL is a 5-
percent shareholder that has increased its ownership interest in L by 
33\1/3\ percentage points during the testing period. For purposes of 
subsequent transactions, Public L and Public EL will continue to be 
treated as separate direct public groups until any subsequent testing 
date that does not have a testing period that includes E's disposition 
of L stock.


[[Page 483]]


    (iii) Other transactions affecting direct public groups of a first 
tier entity or higher tier entity. The rules of paragraphs (j)(2)(i), 
(iii), (iv) and (v) of this section shall apply to transactions 
described in such paragraphs that involve either a higher tier entity 
that owns five percent or more of the loss corporation (determined 
without regard to the application of paragraph (h)(2)(i)(A) of this 
section) or a first tier entity. In applying those rules for purposes of 
this paragraph (j)(3)(iii), each direct public group of a first tier 
entity or a higher tier entity is any public group of any such entity 
identified in paragraph (j)(1)(iv)(A) or (B) of this section or 
resulting from the application of this paragraph (j)(3)(iii). The 
principles of paragraph (j)(2)(iii)(C) of this section also shall apply 
to any transaction that has the effect of a redemption-type transaction 
(e.g., an acquisition by the loss corporation of stock in a first tier 
entity).
    (iv) Examples.

    Example (1) The facts are the same as in Example (1) of paragraph 
(j)(2)(iii)(B)(2) of this section, except that Public L and 
P1 own 40 percent and 60 percent, respectively, of the stock 
of HC which, in turn, owns 100 percent of L and HC merges into 
P2. Under paragraph (j)(3)(iii) of this section, the rules of 
paragraph (j)(2)(iii)(B) of this section apply to segregate HC's direct 
public group (Public L) immediately before the merger from the direct 
public group (Public P2) that acquires loss corporation stock 
in the merger. The consequences of the merger of HC into P2 
are thus the same as in Example (1) of paragraph (j)(2)(iii)(B)(2) of 
this section.
    Example (2) (i) Twenty-five individual shareholders each own four 
percent of L (``Public L''). Public L is therefore the only 5-percent 
shareholder of L. Each of the shareholders of L contribute their L stock 
to a newly formed corporation, HC. In exchange for their contribution of 
L stock, HC issues 100 percent of each of its two classes of common 
stock (voting and nonvoting).
    (ii) The formation of HC, a first tier entity of L, is a transaction 
to which section 1032 applies. Under paragraph (j)(3)(iii) of this 
section, the rules of paragraphs (j)(1)(iii) and (j)(2)(iii)(B) of this 
section are applied to this transaction with the result that the 
shareholders of HC, immediately after the issuance of HC stock, are 
presumed not to include any persons that previously had a direct or 
indirect ownership interest in L. The presumption underlying those 
rules, however, is rebutted by establishing that all of the HC stock 
outstanding immediately after the transaction was issued solely in 
exchange for L stock. Thus, Public HC (immediately after the 
transaction) and Public L (immediately before the transaction) would be 
treated owned by the same direct public group.
    Example (3) (i) All of the stock of L is owned by unrelated 
shareholders, none of whom owns as much as five percent of L stock. P 
also is owned by unrelated shareholders, none of whom owns as much as 
five percent of P stock. On November 22, 1988, P incorporates 
P1 with a contribution of P stock. Immediately thereafter, 
P1 acquires all of the properties of L in exchange for its P 
stock in a forward triangular merger qualifying under sections 368 
(a)(1)(A) and (a)(2)(D). The P stock transferred by P1 equals 
45 percent of the total outstanding P stock.
    (ii) Immediately before the merger of L into P1, P's only 
5-percent shareholder was Public P, a direct public group of P. The 
rules of paragraph (j)(2)(iii)(B) of this section thus apply to the 
transaction under paragraph (j)(3)(i) of this section since P, a first 
tier entity, is a party to the reorganization described in such 
paragraph. Although Public P does not acquire any stock in the merger, 
it is treated as acquiring stock in the loss corporation, P1, 
because such corporation succeeds to the pre-change losses of L in a 
transaction to which 381(a) applies. As a result of the merger, Public 
P, the direct public group of P that exists immediately before the 
merger, must be segregated from the direct public groups acquiring P 
stock in the reorganization. Public P is, therefore, treated as 
acquiring 55 percent of the outstanding stock of the loss corporation, 
P1, in the transaction. The transaction, therefore, results 
in an ownership change for P1.
    Example (4) (i) L is owned 20 percent by A and 80 percent by 1,000 
unrelated individuals and entities, none of whom owns as much as five 
percent of L stock (``Public L''). P is owned 10 percent by B, 40 
percent by E, and 50 percent by 5,000 unrelated individuals, none of 
whom owns as much as five percent of P stock (``Public P''). E is owned 
30 percent by C and 70 percent by 30 unrelated individuals, none of whom 
owns as much as five percent of E (``Public E'').
    (ii) On October 31, 1987, P acquires all of the L stock from A and 
Public L in exchange for P stock representing 20 percent of the value of 
P (determined immediately after the acquisition) in a transaction 
described in section 368(a)(1)(B). After the acquisition, P is owned 
eight percent by B, 32 percent by E, four percent by A, and 56 percent 
by 6,000 unrelated individuals, none of whom owns as much as five 
percent of P. Because L is wholly owned by P immediately after the 
acquisition, L, under paragraph (j)(1) of this section, is treated as 
owned as follows: Eight percent by B, 9.6 percent by C (through C's 
ownership

[[Page 484]]

interest in E, a highest tier entity, and E's ownership interest in P, a 
first tier entity), 22.4 percent by Public E (through its ownership 
interest in E and E's ownership interest in P), four percent by A, and 
56 percent by the shareholders who each own less than five percent of L 
through their ownership interest in P.
    (iii) Under paragraph (j)(3)(iii) of this section, the rules of 
paragraph (j)(2)(iii)(B) of this section apply to the reorganization 
since the transaction involved a first tier entity of L. Thus, the 
direct public group of P that exists immediately after the transaction 
must be segregated into two public groups--the direct public group of P 
that existed immediately before the acquisition (Public P) is treated 
separately from the direct public group consisting of the persons who 
acquire P stock in the transaction (Public L). Accordingly, immediately 
after the reorganization, Public P and Public L own 40 percent and 16 
percent of L, respectively. See paragraph (h) of this section. (Under 
paragraph (g)(5)(ii)(B) of this section, L may treat the four percent of 
L stock owned by A immediately after the reorganization as the amount of 
L stock owned by A for each subsequent testing date having a testing 
period that includes the reorganization.)
    (iv) In summary, after applying the rules of paragraphs (j)(1) and 
(3) of this section, L is treated as owned as follows:

------------------------------------------------------------------------
                                                             Percentage
                   5-percent shareholder                      ownership
                                                              interest
------------------------------------------------------------------------
A.........................................................           4.0
B.........................................................           8.0
C.........................................................           9.6
Public E..................................................          22.4
Public P..................................................          40.0
Public L..................................................          16.0
------------------------------------------------------------------------

    (v) The reorganization results in an ownership change, because B, C, 
Public E and Public P, all of whom are 5-percent shareholders, together 
have increased their percentage ownership in L by 80 percentage points 
as compared to their lowest percentage ownership in L at any time during 
the testing period (0 percent prior to the acquisition).

    (v) Acquisitions made by a 5-percent shareholder, a higher tier 
entity, or a first tier entity following application of the segregation 
rules. The rules of paragraph (j)(2)(vi) of this section shall apply to 
the acquisition of an ownership interest in a first tier entity (or 
higher tier entity) if more than one direct public group of any such 
entity are segregated under the rules of this paragraph (j)(3). 
Accordingly, an acquisition by such an entity or a 5-percent shareholder 
of any ownership interest in such an entity shall be treated as made 
proportionately from the direct public groups resulting from the 
application of this paragraph (j)(3).
    (k) Operating rules--(1) Presumptions regarding stock ownership. 
Subject to paragraphs (k)(2) and (4) of this section, for purposes of 
applying paragraphs (f), (g), (h), and (j)(1) of this section--
    (i) Stock subject to regulation by the Securities and Exchange 
Commission. With respect to loss corporation stock that is described in 
Rule 13d-1(d) of Regulation 13D-G (or any rule or regulation to 
generally the same effect), promulgated by the Securities and Exchange 
Commission under the Securities and Exchange Act of 1934 (``registered 
stock''), a loss corporation may rely on the existence and absence of 
filings of Schedules 13D and 13G (or any similar schedules) as of any 
date to identify all of the corporation's shareholders who have a direct 
ownership interest of five percent or more (both individuals and first 
tier entities) on such date. A loss corporation may similarly rely on 
the existence and absence of such filings as of any date with respect to 
registered stock of any first tier entity or any higher tier entity to 
identify the 5-percent owners of any such entities on such date who 
indirectly own five percent or more of the loss corporation stock, and 
are thus 5-percent shareholders, and to identify any higher tier 
entities of such entities.
    (ii) Statements under penalties of perjury. A loss corporation may 
rely on a statement, signed under penalties of perjury, by an officer, 
director, partner, trustee, executor or similar responsible person, on 
behalf of a first tier entity or a higher tier entity to establish the 
extent, if any, to which the ownership interests of any 5-percent owners 
or higher tier entities with respect to such entities have changed 
during a testing period. A loss corporation may not rely on such a 
statement (A) that it knows to be false or (B) that is made by either a 
first tier entity or higher tier entity that owns 50 percent or more of 
the stock of the loss corporation. For purposes of the preceding 
sentence, any first tier entities and higher tier entities that are 
known by the loss corporation to be members of

[[Page 485]]

the same controlled group (within the meaning of section 267(f)) shall 
be treated as one corporation.
    (2) Actual knowledge regarding stock ownership. For purposes of this 
section (other than paragraphs (g)(5) and (j)(1)(v) of this section), to 
the extent that the loss corporation has actual knowledge of stock 
ownership on any testing date (or acquires such knowledge before the 
date that the income tax return is filed for the taxable year in which 
the testing date occurs) by--
    (i) An individual who would be a 5-percent shareholder, but for the 
application of paragraphs (h)(2)(iii), (h)(6)(iii) or (g)(2) of this 
section, or
    (ii) A 5-percent shareholder that would be taken into account, but 
for paragraphs (h)(2)(iii), (h)(6)(iii) or (g)(3) of this section,

the loss corporation must take such stock ownership into account for 
purposes of determining whether an ownership change has occurred on that 
testing date. If a loss corporation acquires such knowledge after such 
income tax return is filed, the loss corporation may take such ownership 
into account for purposes of determining whether an ownership change 
occurred on that testing date and, if appropriate, file an amended 
income tax return (subject to any applicable statute of limitations). To 
the extent the loss corporation has actual knowledge on or after any 
testing date regarding the ownership interest in the loss corporation by 
members of one public group (described in paragraphs (g)(1)(ii), (iii) 
or (iv) of this section) and the ownership interest of those members in 
the loss corporation as members in another such public group, the loss 
corporation may take such ownership into account for purposes of 
determining whether an ownership change occurred on that testing date.
    (3) Duty to inquire as to actual stock ownership in the loss 
corporation. For purposes of this section, the loss corporation is 
required to determine the stock ownership on each testing date (and, 
except as otherwise provided in this section, the changes in the stock 
ownership during the testing period) of--
    (i) Any individual shareholder who has a direct ownership interest 
of five percent or more in the loss corporation,
    (ii) Any first tier entity,
    (iii) Any higher tier entity that has an indirect ownership interest 
of five percent or more in the loss corporation (determined without 
regard to paragraph (h)(2)(i)(A) of this section), and
    (iv) Any 5-percent owner who indirectly owns five percent or more of 
the stock of the loss corporation in his capacity as a 5-percent owner 
in any one first tier entity or higher tier entity.

The loss corporation does not have any obligation to inquire or to 
determine facts relating to the stock ownership of any shareholders 
other than those described in the preceding sentence. In addition, the 
loss corporation does not have any obligation to inquire or to determine 
if the actual facts relating to the stock ownership of any shareholder 
are consistent with the ownership interests of the loss corporation as 
determined by applying the presumptions and other rules of paragraphs 
(g), (h), (j) or (k)(1) of this section.
    (4) Ownership interest structured to avoid the section 382 
limitation. For purposes of this section, if the ownership interests in 
a loss corporation are structured by a person with a direct or indirect 
ownership interest in the loss corporation to avoid treating a person as 
a 5-percent shareholder (or to permit the loss corporation to rely on 
the presumption provided in paragraph (g)(5)(i)(B) of this section) for 
a principal purpose of circumventing the section 382 limitation, then--
    (i) Paragraph (h)(2)(iii) of this section shall not apply with 
respect to the ownership interests so structured and the constructive 
ownership rules of paragraph (h)(2)(i) of this section shall thus apply 
to attribute stock from any entity without regard to the amount of stock 
it owns in the loss corporation or any other corporation,
    (ii) Paragraphs (g)(2) and (3) of this section shall be modified 
with respect to the ownership interests so structured so that the 
ownership interest of a person includes all of an individual's direct 
and indirect ownership in the loss corporation, without regard to 
whether each such interest represents five percent or more of the stock 
of the loss corporation, and

[[Page 486]]

    (iii) Paragraph (g)(5)(i)(B) of this section shall not apply with 
respect to the ownership interests so structured so that the ownership 
interest of a person takes into account his actual ownership interest in 
the loss corporation.

This paragraph (k)(4) shall apply, however, only if application would 
result in an ownership change.
    (5) Example.

     L is owned by 25 individuals who each own four percent of the 
outstanding L stock. A purchases 40 percent of L stock from such 
shareholders on August 13, 1988. Thereafter, B plans to acquire 15 
percent of the L stock. B is advised concerning the potential 
application of section 382 to L. On February 1, 1989, B acquires a 15 
percent interest in L pursuant to a program in which each of four 
corporations, P1 through P4, each of which is 
wholly-owned by B, acquire a 3.75 percent interest in L. A principal 
purpose of acquiring the L stock through four corporations is to avoid 
treating B as owning any ownership interest in L amounting to as much as 
five percent, and thus to circumvent the section 382 limitation by 
avoiding an ownership change. Under paragraph (k)(4) of this section, 
the limitation on the constructive ownership rules of paragraph 
(h)(2)(iii) of this section are disregarded and B is treated as a 5-
percent shareholder owning 15 percent of the stock of L by virtue of his 
ownership interests in P1 through P4, 
notwithstanding paragraph (g)(2) of this section. Accordingly, an 
ownership change occurs with respect to L.

    (6) First tier entity or higher tier entity that is a foreign 
corporation or entity. [Reserved]
    (l) Changes in percentage ownership which are attributable to 
fluctuations in value. [Reserved]
    (m) Effective date--(1) In general. Except as provided in this 
paragraph (m), section 382 shall apply to any ownership change that 
occurs immediately after an owner shift or an equity structure shift 
that occurs after December 31, 1986, or any other event occurring after 
such date that requires the determination of whether an ownership change 
has occurred under paragraph (a)(2)(i) of this section. In the case of 
an equity structure shift (including an equity structure shift that also 
constitutes an owner shift), any equity structure shift completed 
pursuant to a plan of reorganization adopted before January 1, 1987, 
shall be treated as occurring on the date such plan was adopted. 
Therefore, section 382 shall apply to any ownership change occurring 
immediately after--
    (i) An owner shift (excluding an owner shift that also constitutes 
an equity structure shift) that occurs on or after January 1, 1987,
    (ii) An equity structure shift that occurs after December 31, 1986, 
if it is completed pursuant to a plan of reorganization adopted on or 
after January 1, 1987, or
    (iii) Any transfer or issuance of an option, or other interest that 
is similar to an option, that occurs on or after January l, 1987 and 
that is taken into account under paragraph (a)(2)(i) of this section.

With respect to equity structure shifts completed pursuant to plans 
adopted before January 1, 1987, section 382 shall be inapplicable only 
if the equity structure shift that is treated as occurring on the date 
the plan of reorganization for such shift was adopted (or other event 
occurring after the adoption of such plan) results in an ownership 
change before January 1, 1987. In that event, a new testing period for 
the loss corporation shall begin on the day after such ownership change.
    (2) Plan of reorganization. For purposes of paragraph (m)(1) of this 
section, a plan of reorganization shall be treated as adopted on the 
earlier of--
    (i) The first date that the boards of directors of all the parties 
to the reorganization have adopted the plan or have recommended adoption 
to their shareholders, or
    (ii) The date the shareholders approve such reorganization.

If there is an ownership change with respect to a subsidiary as the 
result of a reorganization of the parent, the treatment of the 
subsidiary under this paragraph (m)(2) shall be governed by the 
classification of the parent-level transaction. For purposes of the 
preceding sentence, a corporation shall be treated as a subsidiary of 
another corporation only if the other corporation owns stock in that 
corporation meeting the requirements of section 1504(a)(2).
    (3) Earliest commencement of the testing period. For purposes of 
determining if an ownership change has occurred at any time after May 5, 
1986, the testing period shall begin no earlier than May

[[Page 487]]

6, 1986. Under paragraph (d)(4) of this section, therefore, shifts in 
the ownership of stock of the loss corporation prior to May 6, 1986 are 
disregarded.
    (4) Transitional rules--(i) Rules provided in paragraph (j) of this 
section for testing dates before September 4, 1987. For purposes of 
determining whether an ownership change occurs for any testing date 
before September 4, 1987.
    (A) The rules of paragraph (j)(1) of this section shall apply only 
to stock of the loss corporation acquired after May 5, 1986, by any 
first tier entity or higher tier entity and shall not apply to any stock 
acquired by such an entity on or before that date,
    (B) The rules of paragraph (j)(2) of this section shall apply only 
to equity structure shifts in which more than one corporation is a party 
to the reorganization and shall not apply to any other transactions, and
    (C) The rules of paragraph (j)(3) of this section shall apply only 
to--
    (1) Dispositions of stock acquired by an individual, a first tier 
entity or higher tier entity after May 5, 1986 (and shall not apply to 
dispositions of stock acquired on or before such date), and
    (2) Equity structure shifts in which more than one corporation is a 
party to the reorganization (and shall not apply to any other 
transactions).

For any testing date before September 4, 1987, however, the loss 
corporation is permitted to apply all of the rules of paragraph (j) of 
this section. A loss corporation that applies the rules of paragraph (j) 
of this section under the preceding sentence must apply all of the rules 
of such paragraph in determining whether any ownership change occurs on 
any testing dates after May 5, 1986.
    (ii) Example.

     (i) L is owned entirely by 10,000 unrelated individuals, none of 
whom owns as much as five percent of the stock of L (``Public L''). P is 
owned entirely by 1,000 unrelated individuals, none of whom owns as much 
as five percent of the stock of P (``Public P'').
    (ii) Between March 1, 1987 and June 1, 1987, P acquires 45 percent 
of L stock in a series of transactions. On June 15, 1987, L redeems 20 
percent of the L stock from Public L.
    (iii) Under paragraph (m)(4)(i)(A) of this section, the rules of 
paragraph (j)(1) of this section apply to the acquisitions made by P, 
because they occurred after May 5, 1986. Accordingly, following those 
acquisitions, the stock of L is owned 45 percent by Public P and 55 
percent by Public L. Because the increase in the percentage ownership by 
Public P as a result of P's stock purchases is not more than 50 percent, 
no ownership change occurs as the result of P's purchases.
    (iv) On or after September 4, 1987, the rules of paragraph 
(j)(2)(iii)(C) of this section apply to treat any L stock that is 
redeemed as owned by a public group that is separate from the public 
group owning the stock that is not redeemed. (Under paragraph 
(j)(2)(iii)(C) of this section, the continuing shareholders of Public L, 
who owned 35 percent of the stock of L before the redemption ([55 
percent--20 percent]/100 percent) increase their ownership interest in L 
by 8.8 percentage points as a result of such redemption (43.8 percent--
35 percent)). Those rules, however, do not apply to the June 15, 1987 
redemption because it occurs before the date that paragraph (j)(2)(iii) 
of this section generally is effective. (Until September 4, 1987, 
paragraph (j)(2)(iii) of this section generally is effective only for 
equity structure shifts in which more than one corporation is a party to 
the reorganization.) Solely because of the application of paragraph 
(j)(1) of this section to P's acquisitions of L stock, Public P's 
ownership interest in L as a result of the redemption has increased from 
45 percentage points to 56.2 percentage points which, compared to its 
lowest percentage ownership interest at any time during the testing 
period (0 percent prior to March 1, 1987), is a more than 50 percentage 
point increase thus causing an ownership change with respect to L on 
June 15, 1987.

    (iii) Rules provided in paragraph (j) of this section for testing 
dates on or after September 4, 1987. For purposes of determining whether 
an ownership change occurs for any testing date on or after September 4, 
1987, the rules of paragraphs (j)(2) and (3) of this section shall not 
apply to identify any public group resulting from--
    (A) Any transaction described in such paragraphs (j)(2) and (3), 
unless that transaction is also described in paragraph (m)(4)(i)(B) or 
(C) of this section, or
    (B) Any disposition of stock acquired on or before May 5, 1986, but 
only if such disposition or other transaction occurs before September 4, 
1987. Thus, for example, the rules of paragraph (j)(2)(iii)(D) of this 
section shall apply only to rights to acquire stock of the loss 
corporation issued on or after such date.
    (iv) Rules provided in paragraphs (f)(18)(ii) and (iii) of this 
section. For

[[Page 488]]

purposes of determining whether an ownership change occurs for any 
testing date, the rules of paragraphs (f)(18)(ii) and (iii) of this 
section apply only to stock (or any other ownership interest) that is--
    (A) Issued on or after September 4, 1987, or
    (B) Transferred to (or by) a person who is a 5-percent shareholder 
(or would be a 5-percent shareholder if paragraph (f)(18)(iii) of this 
section were applicable) on or after September 4, 1987.
    (v) Rules provided in paragraph (a)(2)(ii) of this section. The 
information statement required under paragraph (a)(2)(ii) of this 
section is not required to be filed with respect to any taxable year for 
which the due date (including extensions) of the income tax return of 
the loss corporation is on or before October 5, 1987.
    (vi) Rules provided in paragraph (h)(4) of this section. The rules 
provided in paragraph (h)(4) of this section do not apply on any testing 
date on or after November 5, 1992. The rule provided in paragraph 
(h)(4)(viii) of this section applies to the lapse or forfeiture of any 
option treated as exercised under paragraph (h)(4)(i) of this section. 
If an option is treated as exercised under paragraph (h)(4)(i) of this 
section, and the option is actually exercised on a day that is within 
120 days after the date on which the option is treated as exercised, the 
rule provided in paragraph (h)(4)(vi)(B) of this section applies (even 
if the actual exercise of the option occurs on a date on which the rules 
of paragraph (h)(4) of this section would not otherwise apply). Thus, in 
such a case, the loss corporation may elect to treat paragraphs 
(h)(4)(i) and (vi)(A) of this section as not applying to the option and 
take into account only the acquisition of loss corporation stock 
resulting from the actual exercise of the option.
    (vii) Rules provided in paragraph (a)(2)(i) of this section. The 
rules provided in paragraph (a)(2)(i) of this section apply to determine 
whether dates prior to November 5, 1992, are testing dates. For rules 
regarding the determination of whether dates on or after November 5, 
1992, are testing dates, see Sec. 1.382-2(a)(4).
    (5) Bankruptcy proceedings--(i) In general. In the case of a 
reorganization described in section 368(a)(1)(G) or an exchange of debt 
for stock in a title 11 or similar case (within the meaning of section 
368(a)(3)), section 382 shall not apply to any ownership change 
resulting from such a reorganization or proceeding if a petition in such 
case was filed with the court before August 14, 1986. Accordingly, any 
shift in ownership in the loss corporation arising out of such 
reorganization or proceeding shall not be taken into account for 
purposes of determining whether an ownership change occurs on any 
testing date that occurs after December 31, 1986.
    (ii) Example.

     (i) L filed a petition in bankruptcy on September 29, 1985. As a 
result of a title 11 bankruptcy reorganization of L that is confirmed by 
a court on February 2, 1988, there is a shift in the ownership of L so 
that JK increased her interest in L by 24 percentage points relative to 
her lowest ownership interest in L during the testing period. JK is the 
only 5-percent shareholder of L following the reorganization whose 
interest in L increased as a result of the transaction. On December 25, 
1988, GK purchases 42 percent of the outstanding stock of L from 
shareholders other than JK.
    (ii) There is no ownership change on December 25, 1988 because the 
24 percentage point increase in JK's ownership interest in L is not 
taken into account under paragraph (m)(6)(i) of this section.
    (iii) The facts are the same as in (i), except that the acquisitions 
by JK and GK occurred on August 5, 1986 and September 26, 1986, 
respectively. Because paragraph (m)(6)(i) of this section is only 
applicable with respect to the determination of whether an ownership 
change has occurred on any testing date that occurs after December 31, 
1986, there is an ownership change as a result of GK's acquisition on 
September 26, 1986. Accordingly, section 382 is inapplicable to such 
ownership change under paragraph (m)(1) of this section because it 
occurred prior to January 1, 1987. Under paragraph (d)(2) of this 
section, the testing period for determining whether an ownership change 
occurs on any subsequent testing date shall commence no earlier than 
September 27, 1986.

    (6) Transactions of domestic building and loan associations. The 
rules of paragraph (j)(2)(iii)(B) of this section (and the application 
of those rules by virtue of paragraph (j)(3) of this section) shall not 
apply to a public offering of stock

[[Page 489]]

by a domestic building and loan association described in section 591 (or 
any corporation that owns stock in the association meeting the 
requirements of section 1504(a)(2)) prior to January 1, 1989. In the 
case of any transaction described in the preceding sentence, any 
transitory ownership of stock by any entity that is an underwriter shall 
be disregarded so that the rules of paragraph (j)(1) of this section 
shall not apply to treat such stock as owned by the owners of the 
underwriter and thus the rules of paragraph (j)(3)(i) of this section 
shall not apply to the disposition of such stock by the underwriter. For 
purposes of this paragraph (m)(7)--
    (i) Ownership shall be considered transitory only with respect to an 
underwriter acquiring stock in a firm commitment underwriting to the 
extent the stock is disposed of pursuant to the offer (but in no event 
later than sixty (60) days after the initial offering) and,
    (ii) To the extent a transaction may be described both by paragraph 
(j)(2)(iii)(B) of this section and any other provision of paragraph 
(j)(2)(iii) or (3) of this section, paragraph (j)(2)(v)(A) of this 
section shall not apply and the transaction shall be treated as 
described solely by paragraph (j)(2)(iii)(B) of this section.
    (7) Transactions not subject to section 382--(i) Application of old 
section 382. Old section 382 shall not apply to a loss corporation on or 
after the date on which an ownership change occurs, but only if such 
ownership change results in the application of the section 382 
limitation (as defined in section 382(b)) with respect to the loss 
corporation.
    (ii) Effect on testing period. The application of old section 382 to 
a transaction is disregarded for purposes of paragraph (d)(2) of this 
section unless the transaction that results in such application is the 
last component of an ownership change after May 5, 1986 that is not 
subject to section 382 under the effective date rules of this paragraph 
(m) (e.g., an ownership change occurring as the result of an 
individual's purchase of more than 50 percent of L stock on any date on 
or before December 31, 1986).
    (iii) Termination of old section 382. [Reserved]
    (8) Options issued or transferred before January 1, 1987--(i) 
Options issued before May 6, 1986. An option issued before May 6, 1986, 
is subject to the rules of paragraph (h)(4) of this section only if it 
is transferred by (or to) a 5-percent shareholder (or a person who would 
be a 5-percent shareholder if the option were treated as exercised) on 
or after such date. In all other cases, such an option shall not be 
subject to paragraph (h)(4)(i) of this section, but shall be subject to 
paragraph (h)(4)(xii) of this section. Thus, for example, a warrant to 
acquire stock of the loss corporation issued before May 6, 1986 shall 
not be subject to paragraph (h)(4) of this section unless the warrant is 
transferred by (or to) a 5-percent shareholder. The exercise of such a 
warrant, however, would be taken into account as required by this 
paragraph (m)(8)(i) and paragraph (h)(4)(xii) of this section.
    (ii) Options issued on or after May 6, 1986 and before September 18, 
1986. An option issued or transferred on or after May 6, 1986, and 
before September 18, 1986, is subject to the rules of paragraph (h)(4) 
of this section.
    (iii) Options issued on or after September 18, 1986 and before 
January 1, 1987. An option issued or transferred on or after September 
18, 1986, and before January 1, 1987, is subject to the rules of 
paragraph (h)(4) of this section, except that the option shall be 
treated for purposes of this section as if it never had been issued in 
the event that either--
    (A) The option lapses unexercised or is irrevocably forfeited by the 
holder thereof, or
    (B) On the date the option was issued, there was no significant 
likelihood that such option would be exercised within the five-year 
period from the date of such issuance and a purpose for the issuance of 
the option was to cause an ownership change prior to January 1, 1987.
    (9) Examples. The rules of this paragraph (m) may be illustrated by 
the following examples.

    Example (1) (i) A owns all 100 outstanding shares of L stock. A 
sells 11 shares to B on January 1, 1986. The January 1, 1986 testing 
date is disregarded under paragraph (m)(3) of this section. A sells 
another 40 shares to B on

[[Page 490]]

January 1, 1988. B's second stock purchase is an owner shift that does 
not result in an ownership change. B's percentage ownership interest on 
the testing date (51 percent) is only 40 percentage points greater than 
the lowest percentage of L stock owned by B at any time during the 
testing period (11 percent on and after May 6, 1986).
    (ii) The facts are the same as in (i). In addition A sells 20 shares 
of his L stock to C on July 1, 1990. C's stock purchase is an owner 
shift. Because B and C together have increased their respective 
ownership interests in L by 40 and 20 percentage points relative to 
their lowest percentage stock ownership interests in L at any time 
during the testing period, C's purchase causes an ownership change. The 
testing period for any subsequent ownership change begins on the first 
day following C's acquisition, July 2, 1990.
    Example (2) (i) C has owned 100 percent of L since March 22, 1980. 
On October 13, 1986, P merges into L. As a result of the merger, 40 
percent of L stock is acquired by A, the sole shareholder of P. The 
merger of P into L is both an equity structure shift and an owner shift. 
The transaction, however, is not an ownership change with respect to L, 
because A's percentage ownership interest has increased by only 40 
percentage points. On August 22, 1987, B purchases 15 percent of the L 
stock from C. B's purchase constitutes an owner shift resulting in an 
ownership change that is subject to section 382 because the aggregate 
increases in percentage ownership by B and C (respectively 40 percent 
and 15 percent) is more than 50 percentage points.
    (ii) The facts are the same as in (i), except that the plan of 
reorganization is adopted on October 13, 1986, and the merger is 
completed on July 22, 1987. The result is the same as in (i).
    (iii) The facts are the same as in (ii), except that the 
reorganization is completed on August 22, 1987, and B's purchase of the 
L stock occurs one month earlier, on July 22, 1987. Assume that after 
the reorganization on August 22, 1987, A and B own 40 percent and 15 
percent, respectively, of L stock. Although the merger occurred pursuant 
to a plan of reorganization adopted before 1987, L is subject to section 
382 following the equity structure shift, because the merger would not 
have caused an ownership change if it had been completed in 1986 after 
the commencement of the L's testing period.
    (iv) The facts are the same as in (ii), except that B's purchase 
occurs on June 7, 1986. Assume that immediately after the reorganization 
on August 22, 1987, A and B own 40 percent and 15 percent, respectively, 
of L stock. Since the reorganization pursuant to a plan adopted before 
1987, taken together with the other shifts in the ownership of L's stock 
between May 5, 1986, and December 31, 1986, would have caused an 
ownership change, section 382 does not apply as a result of the merger. 
Since an ownership change occurs as a result of the merger, L's testing 
period for purposes of any subsequent ownership change begins on October 
14, 1986.
    (v) The facts are the same as in (iv), except that B makes an 
additional purchase from C of one percent of L's stock on February 14, 
1987. The result is the same as in (iv). B's additional purchase, 
however, is taken into account for the purpose of determining whether 
there is a second ownership change with respect to L.
