Sec. 1.381(c)(23)-1  Investment credit carryovers in certain corporate 
acquisitions.

    (a) Carryover requirement. (1) Section 381(c)(23) requires the 
acquiring corporation in a transaction to which section 381 applies to 
succeed to and take into account under such regulations as may be 
prescribed by the Secretary or his delegate, the investment credit 
carryovers of the distributor or transferor corporation. To determine 
the amount of these carryovers as of the close of the date of 
distribution or transfer, and to integrate them with any carryovers and 
carrybacks of the acquiring corporation for purposes of determining the 
amount of credit allowed by section 38 to the acquiring corporation for 
taxable years ending after the date of distribution or transfer, it is 
necessary to apply the provisions of sections 46, 47, and 48 in 
accordance with the conditions and limitations of this section.
    (2) The investment credit carryovers and carrybacks of the acquiring 
corporation determined as of the close of the date of distribution or 
transfer

[[Page 440]]

shall be computed without reference to any unused credit of a 
distributor or transferor corporation. The investment credit carryovers 
of a distributor or transferor corporation as of the close of the date 
of distribution or transfer shall be determined without reference to any 
unused credit of the acquiring corporation.
    (b) Carryback of unused credits. An unused credit of the acquiring 
corporation for any taxable year ending after the date of distribution 
or transfer shall not be carried back in computing the credit allowed by 
section 38 to a distributor or transferor corporation. However, an 
unused credit of the acquiring corporation for any such taxable year 
shall be carried back in accordance with section 46(b)(1) in computing 
the credit allowed to the acquiring corporation for a taxable year 
ending on or before the date of distribution or transfer. If a 
distributor or transferor corporation remains in existence after the 
date of distribution or transfer, an unused credit sustained by it for 
any taxable year beginning after such date shall be carried back in 
accordance with section 46(b)(1) in computing the credit allowed by 
section 38 to such corporation for a taxable year ending on or before 
that date, but may not be carried back or over in computing the credit 
allowed by section 38 to the acquiring corporation.
    (c) Computation of carryovers and carrybacks. (1) Subject to the 
modifications set forth in this paragraph, the provisions of Sec. 1.46-
2 shall apply in computing carryovers and carrybacks of unused credits 
to taxable years of the acquiring corporation.
    (2)(i) The investment credit carryovers available to the distributor 
or transferor corporation as of the close of the date of distribution or 
transfer shall first be carried to the first taxable year of the 
acquiring corporation ending after that date. This rule applies whether 
the date of distribution or transfer is on the last day, or any other 
day, of the acquiring corporation's taxable year.
    (ii) The investment credit carryovers available to the distributor 
or transferor corporation as of the close of the date of distribution or 
transfer shall be carried to the acquiring corporation without 
diminution by reason of the fact that the acquiring corporation does not 
acquire 100 percent of the assets of the distributor or transferor 
corporation.
    (3) An unused credit of a distributor or transferor corporation for 
a taxable year which ends on or before the last day of a taxable year of 
the acquiring corporation shall be considered to be an unused credit for 
a year prior to such taxable year of the acquiring corporation. If the 
acquiring corporation has acquired the assets of two or more distributor 
or transferor corporations on the same date of distribution or transfer, 
the unused credit years of the distributor or transferor corporations 
shall be taken into account in the order in which such years terminate. 
If any one of the unused credit years of a distributor or transferor 
corporation ends on the same day as the unused credit year of another 
distributor or transferor corporation, either unused credit year may be 
taken into account before the other.
    (4) The extent to which an investment credit carryover of a 
distributor or transferor corporation or of an acquiring corporation 
from an unused credit year ending before January 1, 1971, may be taken 
into account by the acquiring corporation for a taxable year beginning 
after December 31, 1970, shall be determined without regard to the 
credit earned by the acquiring corporation for such year. Thus, in such 
a case, the amount of unused credit from such unused credit years which 
may be taken into account in a taxable year of the acquiring corporation 
beginning after December 31, 1970, shall be determined solely with 
reference to the limitation based on amount of tax for such taxable year 
(without reduction for the credit earned for such year).
    (d) Computation of carryovers when date of distribution or transfer 
occurs on last day of acquiring corporation's taxable year. The 
computation of the investment credit carryovers from the distributor or 
transferor corporation and from the acquiring corporation in a case 
where the date of distribution or transfer occurs on the last day of a 
taxable year of the acquiring corporation may be illustrated by the 
following example:

    Example. X Corporation and Y Corporation were organized on January 
1, 1971, and each corporation files its return on the calendar year 
basis. On December 31, 1972, X transfers all its assets to Y in a 
statutory merger to which section 361 applies. X's credit earned and its 
limitation based on amount of tax for its taxable years 1971 and 1972 
are as follows:

Carryover to Y's year 1974...................................      2,000


    (5) The aggregate of the investment credit carryovers to Y's year 
1974 is $3,000, computed as follows:

X's 1972 unused credit.......................................     $1,000
Y's 1972 unused credit.......................................      2,000
                                                              ----------
    Total....................................................      3,000



    (e) Computation of carryovers when date of distribution or transfer 
is not on last day of acquiring corporation's taxable year. (1) If the 
date of distribution or transfer occurs on any day other than the last 
day of a taxable year of the acquiring corporation, the amount which may 
be added to the amount allowable as a credit by section 38 for the first 
taxable year of the acquiring corporation ending after the date of 
distribution or transfer (hereinafter called the ``year of 
acquisition'') shall be determined in the following manner. The year of 
acquisition shall be considered as though it were 2 taxable years. The 
first of such 2 taxable years shall be referred to in this paragraph as 
the preacquisition part year and shall begin with the beginning of the 
year of acquisition and end with the close of the date of distribution 
or transfer. The second of such 2 taxable years shall be referred to in 
this paragraph as the postacquisition part year and shall begin with the 
day following the date of distribution or transfer and shall end with 
the close of the year of acquisition.
    (2) The excess limitation for the year of acquisition (i.e., the 
excess of the limitation based on the amount of tax for such year over 
the amount of credit earned for such year) shall be divided between the 
preacquisition part year and the postacquisition part year in proportion 
to the number of days in each. Thus, if in a statutory merger to

[[Page 442]]

which section 361 applies Y Corporation, a calendar year taxpayer, 
acquires the assets of X Corporation on June 30, 1975, and Y Corporation 
has an excess limitation of $36,500 for its calendar year 1975, then the 
excess limitation for the preacquisition part year would be $18,100 
($36,500x181/365) and the excess limitation for the postacquisition part 
year would be $18,400 ($36,500x184/365).
    (3) An unused credit of the acquiring corporation shall be carried 
to and applied against the excess limitation for the preacquisition part 
year and then carried to and applied against the excess limitation for 
the postacquisition part year, whereas an unused credit of the 
distributor or transferor corporation shall not be carried to the 
preacquisition part year but shall only be carried to and applied 
against the excess limitation for the postacquisition part year. For 
special rule relating to carryovers from taxable years ending before 
January 1, 1971, to taxable years beginning after December 31, 1970, see 
subparagraph (6) of this paragraph.
    (4) Though considered as two separate taxable years for purposes of 
this paragraph, the preacquisition part year and the postacquisition 
part year are treated as one taxable year in determining the years to 
which an unused credit is carried under section 46(b)(1).
    (5) The preceding subparagraphs may be illustrated by the following 
example:

    Example. X Corporation and Y Corporation were organized on January 
1, 1971, and each corporation files its return on the calendar year 
basis. On May 1, 1972, X transfers all its assets to Y in a statutory 
merger to which section 361 applies. X's credit earned and its 
limitation based on amount of tax for its taxable years 1971 and ending 
May 1, 1972, are as follows:

------------------------------------------------------------------------
                                                            Limitation
     X Corporation's taxable year        Credit earned   based on amount
                                                              of tax
------------------------------------------------------------------------
1971..................................          $11,000           $5,000
Ending 5-1-72.........................            3,000            6,000
------------------------------------------------------------------------


Y's credit earned and its limitation based on amount of tax for its 
taxable years 1971 and 1972 are as follows:

------------------------------------------------------------------------
                                                            Limitation
     Y Corporation's taxable year        Credit earned   based on amount
                                                              of tax
------------------------------------------------------------------------
1971..................................           $7,000           $3,000
1972..................................            3,000            9,000
------------------------------------------------------------------------

The sequence for the allowance of unused credits of X Corporation and Y 
Corporation, and the computation of carryovers to Y Corporation's 
calendar year 1973, may be illustrated as follows:
    (i) X Corporation's 1971 unused credit. The carryover to Y 1973 is 
$0, computed as follows:

Unused credit................................................     $6,000
  Excess of X's 5-1-72 limitation based on tax over credit         3,000
   earned....................................................

Carryover to Y's year 1973...................................          0


    (ii) Y Corporation's 1971 unused credit. The carryover to Y 1973 is 
$1,000, computed as follows:

Unused credit................................................     $4,000
  Excess limitation for Y's preacquisition part year               2,000
   ($6,000x122/ 366).........................................

  Excess limitation for Y's postacquisition part year              4,000
   ($6,000x 244/366).........................................
  Less: X's $3,000 carryover from 1971.......................      3,000
                                                              ----------
                                                                   1,000
                                                              ==========
  Carryover to Y's year 1973.................................      1,000


    (iii) The aggregate of the investment credit carryovers to Y's year 
1973 is $1,000, computed as follows:

X's 1971 unused credit.......................................          0
Y's 1971 unused credit.......................................     $1,000
                                                              ----------
    Total....................................................      1,000


    (6) If the year of acquisition is a taxable year beginning after 
December 31, 1970, and if there is an unused credit of the distributor 
or transferor corporation or of the acquiring corporation arising in an 
unused credit year ending before January 1, 1971, which may be carried 
to such year of acquisition (see paragraph (c)(4) of this section), then 
in applying subparagraphs (1), (2), and (3) of this paragraph, in lieu 
of dividing the excess limitation for the year of acquisition between 
the preacquisition and postacquisition part years, only the limitation 
based on the amount of tax for such year (i.e., without reduction for 
the credit earned) shall be divided between the preacquisition and 
postacquisition part years. If there is

[[Page 443]]

also an unused credit arising in an unused credit year ending after 
December 31, 1970, which may be carried to the year of acquisition, then 
for the purpose of determining the amount of such unused credit which 
may be taken into account for such year of acquisition, the credit 
earned for the year of acquisition shall first be applied against the 
limitation based on amount of tax for the preacquisition part year 
(reduced by any investment credit carryovers to such part year from 
unused credit years ending before January 1, 1971) and the excess, if 
any, shall then be applied against the limitation based on amount of tax 
for the postacquisition part year (also reduced by any investment credit 
carryovers to such part year from unused credit years ending before 
January 1, 1971).
    (7) Subparagraph (6) of this paragraph may be illustrated by the 
following example:

    Example. X Corporation and Y Corporation were organized on January 
1, 1970, and each corporation files its return on the calendar year 
basis. On May 1, 1972, X transfers all its assets to Y in a statutory 
merger to which section 361 applies. X's credit earned and its 
limitation based on amount of tax for its taxable years 1970, 1971, and 
ending May 1, 1972, are as follows:

------------------------------------------------------------------------
                                                            Limitation
     X Corporation's taxable year        Credit earned   based on amount

Ending 5-1-72.........................              200  ...............
------------------------------------------------------------------------


Y's credit earned and its limitation based on amount of tax for its 
taxable years 1970 through 1972 are as follows:

------------------------------------------------------------------------
                                                            Limitation
     Y Corporation's taxable year        Credit earned   based on amount
                                                              of tax
------------------------------------------------------------------------
1970..................................             $100  ...............
1971..................................              200
1972..................................              300             $900
------------------------------------------------------------------------

The sequence for the allowance of unused credits of X Corporation and Y 
Corporation, and the computation of carryovers to Y Corporation's 
calendar year 1973, may be illustrated as follows:
    (i) X Corporation's 1970 unused credit.-- The carryover to Y 1973 is

    (8) If the year of acquisition is a taxable year to which the 
limitation provided in Sec. 1.46-2(b)(2) (relating to 20- percent 
limitation on carryovers and carrybacks to certain taxable years) 
applies, then for purposes of applying such limitation the 
preacquisition part year and the postacquisition part year shall each be 
considered a fractional part of a year, but, if the date of distribution 
or transfer is not on the last day of a month, the entire month in which 
the date of distribution or transfer occurs shall be considered as 
included in the preacquisition part year and no portion thereof shall be 
considered as included in the postacquisition part year.
    (9) If the acquiring corporation succeeds to the investment credit 
carryovers of two or more distributor or transferor corporations on two 
or more dates of distribution or transfer during the same taxable year 
of the acquiring corporation, the manner in which the unused credits of 
the distributor or transferor corporations shall be applied shall be 
determined consistently with the rules prescribed in paragraph (c) of 
Sec. 1.381(c)(1)-2.
    (f) Successive acquiring corporations. An acquiring corporation 
which, in a distribution or transfer to which section 381(a) applies, 
acquires the assets of a distributor or transferor corporation which 
previously acquired the assets of another corporation in a transaction 
to which section 381(a) applies, shall succeed to and take into account, 
subject to the conditions and limitations of Sec. 1.46-2 and this 
section, the investment credit carryovers available to the first 
acquiring corporation under Sec. 1.46-2 and this section.
    (g) Recomputation of credit allowed by section 38 on certain 
property of acquiring corporation. If section 38 property acquired by an 
acquiring corporation in a transaction to which section 381(a) applies 
is disposed of, or otherwise ceases to be section 38 property (or 
becomes public utility property) with respect to the acquiring 
corporation, before the close of the estimated useful life which was 
taken into account in computing the distributor or transferor 
corporation's qualified investment, see paragraph (e) of Sec. 1.47-3.
    (h) Electing small business corporation. An unused credit of a 
distributor or transferor corporation arising in an unused credit year 
for which such corporation is not an electing small business corporation 
(as defined in section 1371(b)) may not be carried over in a transaction 
to which section 381 applies to a taxable year of the acquiring 
corporation for which such corporation is an electing small business 
corporation and may not be added to the amount allowable as a credit 
under section 38 to the shareholders of the acquiring corporation for 
such taxable

year. However, in such a case, a taxable year for which the acquiring 
corporation is an electing small business corporation shall be counted 
as a taxable year for purposes of determining the taxable years to which 
such unused credit may be carried.
