                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.279-5  Rules for application of section 279(b).

    (a) Taxable years to which applicable--(1) First year of 
disallowance. Under section 279(d)(1), the deduction of interest on any 
obligation shall not be disallowed under section 279(a) before the first 
taxable year of the issuing corporation as of the last day of which the 
application of either section 279(b)(4) (A) or (B) results in such 
obligation being classified as corporate acquisition indebtedness. See 
section 279(c)(1) and paragraph (b)(2) of this section for the time when 
an obligation is subjected to the test of section 279(b)(4).
    (2) General rule for succeeding years. Under section 279(d)(2), 
except as provided in paragraphs (3), (4), and (5) of section 279(d), if 
an obligation is determined to be corporate acquisition indebtedness as 
of the last day of any taxable year of the issuing corporation, such 
obligation shall be corporate acquisition indebtedness for such taxable 
year and all subsequent taxable years.
    (b) Time of determination--(1) In general. The determination of 
whether an obligation meets the conditions of section 279(b) (1), (2), 
and (3) shall be made as of the day on which the obligation is issued.
    (2) Ratio of debt to equity, projected earnings, and annual interest 
to be paid or incurred. (i) Under section 279(c)(1), the determination 
of whether an obligation meets the conditions of section 279(b)(4) is 
first to be made as of the last day of the taxable year of the issuing 
corporation in which it issues the obligation to provide consideration 
directly or indirectly for an acquisition described in section 279(b)(1) 
of stock in, or assets of, the acquired corporation. An obligation which 
is not corporate acquisition indebtedness only because it does not 
satisfy the test of section 279(b)(4) in the taxable year of the issuing 
corporation in which the obligation is issued for stock in, or assets 
of, the acquired corporation may be subjected to the test of section 
279(b)(4) again. A retesting will occur in any subsequent taxable year 
of the issuing corporation in which the issuing corporation issues any 
obligation to provide consideration directly or indirectly for an 
acquisition described in section 279(b)(1) with respect to the same 
acquired corporation, irrespective of whether such subsequent obligation 
is itself classified as corporate acquisition indebtedness. If the 
issuing corporation is a member of an affiliated group, then in 
accordance with section 279(g) the affiliated group shall be treated as 
the issuing corporation. Thus, if any member of the affiliated group 
issues an obligation to acquire additional stock in, or assets of, the 
acquired corporation, this paragraph shall apply.
    (ii) For purposes of section 279(b)(4) and this paragraph, in any 
case where the issuing corporation is a member of an affiliated group 
(see section 279(g) and Sec. 1.279-6 for rules regarding application of 
section 279 to certain affiliated groups) which does not file a 
consolidated return and all the members of which do not have the same 
taxable year, determinations with respect to

[[Page 652]]

the ratio of debt to equity of, and projected earnings of, and annual 
interest to be paid or incurred by, any member of the affiliated group 
shall be made as of the last day of the taxable year of the corporation 
which in fact issues the obligation to provide consideration for an 
acquisition described in section 279(b)(1).
    (3) Redetermination where control or substantially all the 
properties have been acquired. Under section 279(d)(3), if an obligation 
is determined to be corporate acquisition indebtedness as of the close 
of a taxable year of the issuing corporation in which section 
279(c)(3)(A)(i) (relating to the projected earnings of the issuing 
corporation only) applied, but would not be corporate acquisition 
indebtedness if the determination were made as of the close of the first 
taxable year of such corporation thereafter in which section 
279(c)(3)(A)(ii) (relating to the projected earnings of both the issuing 
corporation and the acquired corporation) could apply, such obligation 
shall be considered not to be corporate acquisition indebtedness for 
such later taxable year and all taxable years thereafter. Where an 
obligation ceases to be corporate acquisition indebtedness as a result 
of the application of this paragraph, the interest on such obligation 
shall not be disallowed under section 279(a) as a deduction for the 
taxable year in which the obligation ceases to be corporate acquisition 
indebtedness and all taxable years thereafter. However, under section 
279(a)(2) the interest paid or incurred on such obligation which is 
allowed as a deduction will reduce the $5 million limitation provided by 
section 279(a)(1).
    (4) Examples. The provisions of this paragraph may be illustrated by 
the following examples:

    Example 1. In 1971, X Corporation, which files its Federal income 
tax return on the basis of a calendar year, issues its obligations to 
provide consideration for the acquisition of 15 percent of the voting 
stock of both Y Corporation and Z Corporation. Y Corporation and Z 
Corporation each have only one class of stock. When issued, such 
obligations satisfied the tests prescribed in section 279(b) (1), (2), 
and (3) and would have constituted corporate acquisition indebtedness 
but for the test prescribed in section 279(b)(4). On December 31, 1971, 
the application of section 279(b)(4) results in X Corporation's 
obligations issued in 1971 not being treated as corporate acquisition 
indebtedness for that year.
    Example 2. Assume the same facts as in Example 1, except that in 
1972, X Corporation issues more obligations which come within the tests 
of section 279(b) (1), (2), and (3) to acquire an additional 10 percent 
of the voting stock of Y Corporation. No stock of Z Corporation is 
acquired after 1971. The application of section 279(b)(4)(B) (relating 
to the projected earnings of X Corporation) as of the end of 1972 
results in the obligations issued in 1972 to provide consideration for 
the acquisition of the stock of Y Corporation being treated as corporate 
acquisition indebtedness. Since X Corporation during 1972 did issue 
obligations to acquire more stock of Y Corporation, under the provisions 
of section 279(c)(1) and subparagraph (2) of this paragraph the 
obligations issued by X Corporation in 1971 to acquire stock in Y 
Corporation are again tested to determine whether the test of section 
279(b)(4) with respect to such obligations is satisfied for 1972. Thus, 
since such obligations issued by X Corporation to acquire Y 
Corporation's stock in 1971 previously came within the provisions of 
section 279(b) (1), (2), and (3) and the projected earnings test of 
section 279(b)(4)(B) is satisfied for 1972, all of such obligations are 
to be deemed to constitute corporate acquisition indebtedness for 1972 
and subsequent taxable years. The obligations issued in 1971 to acquire 
stock in Z Corporation continue not to constitute corporate acquisition 
indebtedness.
    Example 3. Assume the same facts as in Examples 1 and 2. In 1973, X 
Corporation issues more obligations which come within the tests of 
section 279(b) (1), (2), and (3) to acquire more stock (but not control) 
in Y Corporation. On December 31, 1973, it is determined with respect to 
X Corporation that neither of the conditions described in section 
279(b)(4) are present. Thus, the obligations issued in 1973 do not 
constitute corporate acquisition indebtedness. However, the obligations 
issued in 1971 and 1972 by X Corporation to acquire stock in Y 
Corporation continue to be treated as corporate acquisition 
indebtedness.
    Example 4. Assume the same facts as in Example 3, except that X 
Corporation acquires control of Y Corporation in 1973. Since X 
Corporation has acquired control of Y Corporation, the average annual 
earnings (as defined in section 279(c)(3)(B) and the annual interest to 
be paid or incurred (as provided by section 279(c)(4)) of both X 
Corporation and Y Corporation under section 279(c)(3)(A)(ii) are taken 
into account in computing for 1973 the ratio of projected earnings to 
annual interest to be paid or incurred described in section 
279(b)(4)(B). Assume further that after applying section

[[Page 653]]

279(b)(4)(B) the obligations issued in 1973 escape treatment as 
corporate acquisition indebtedness for 1973. Under section 279(d)(3), 
all of the obligations issued by X Corporation to acquire stock in Y 
Corporation in 1971 and 1972 are removed from classification as 
corporate acquisition indebtedness for 1973 and all subsequent taxable 
years.
    Example 5. In 1975, M Corporation, which files its Federal income 
tax return on the basis of a calendar year, issues its obligations to 
acquire 30 percent of the voting stock of N Corporation. N Corporation 
has only one class of stock. Such obligations satisfy the tests 
prescribed in section 279(b) (1), (2), and (3). Additionally, as of the 
close of 1975, M Corporation's ratio of debt to equity exceeds the ratio 
of 2 to 1 and its projected earnings do not exceed three times the 
annual interest to be paid or incurred. The obligations issued by M 
Corporation are corporate acquisition indebtedness for 1975 since all 
the provisions of section 279(b) are satisfied. In 1976 M Corporation 
issues its obligations to acquire from the shareholders of N Corporation 
an additional 60 percent of the voting stock of N Corporation, thereby 
acquiring control of N Corporation. However, with respect to the 
obligations issued by M Corporation in 1975, there is no redetermination 
under section 279(d)(3) and subparagraph (3) of this paragraph as to 
whether such obligations may escape classification as corporate 
acquisition indebtedness because in 1975 it was the ratio of debt to 
equity test which caused such obligations to be corporate acquisition 
indebtedness. If in 1975, M Corporation met the conditions of section 
279(b)(4) solely because of the ratio of projected earnings to annual 
interest to be paid or incurred described in section 279(b)(4)(B), its 
obligation issued in 1975 could be retested in 1976.

    (c) Acquisition of stock or assets of several corporations. An 
issuing corporation which acquires stock in, or assets of, more than one 
corporation during any taxable year must apply the tests described in 
section 279(b) (1), (2), and (3) separately with respect to each 
obligation issued to provide consideration for the acquisition of the 
stock in, or assets of, each such acquired corporation. Thus, if an 
acquisition is made with obligations of the issuing corporation that 
satisfy the tests described in section 279(b) (2) and (3) and 
obligations that fail to satisfy such tests, only those obligations 
satisfying such tests need be further considered to determine whether 
they constitute corporate acquisition indebtedness. Those obligations 
which meet the test of section 279(b)(1) but which are not deemed 
corporate acquisition indebtedness shall be taken into account for 
purposes of determining the reduction in the $5 million limitation of 
section 279(a)(1).
    (d) Ratio of debt to equity and projected earnings--(1) In general. 
One of the four tests to determine whether an obligation constitutes 
corporate acquisition indebtedness is contained in section 279(b)(4). An 
obligation will meet the test of section 279(b)(4) if, as of a day 
determined under section 279(c)(1) and paragraph (b)(2) of this section, 
either:
    (i) The ratio of debt to equity (as defined in paragraph (f) of this 
section) of the issuing corporation exceeds 2 to 1, or
    (ii) The projected earnings (as defined in subparagraph (2) of this 
paragraph) of the issuing corporation, or of both the issuing 
corporation and acquired corporation in any case where subparagraph 
(2)(ii) of this paragraph is applicable, do not exceed three times the 
annual interest to be paid or incurred (as defined in paragraph (e) of 
this section) by such issuing corporation, or, where applicable, by such 
issuing corporation and acquired corporation. Where paragraphs 
(d)(2)(ii) and (e)(1)(ii) of this section are applicable in computing 
projected earnings and annual interest to be paid or incurred, 100 
percent of the acquired corporation's projected earnings and annual 
interest to be paid or incurred shall be included in such computation, 
even though less than all of the stock or assets of the acquired 
corporation have been acquired.
    (2) Projected earnings. The term projected earnings means the 
``average annual earnings'' (as defined in subparagraph (3) of this 
paragraph) of:
    (i) The issuing corporation only, if subdivision (ii) of this 
subparagraph, does not apply, or
    (ii) Both the issuing corporation and the acquired corporation, in 
any case where the issuing corporation as of the close of its taxable 
year has acquired control, or has acquired substantially all of the 
properties, of the acquired corporation.

For purposes of subdivision (ii) of this subparagraph, an acquisition of 
``substantially all of the properties'' of the

[[Page 654]]

acquired corporation means the acquisition of assets representing at 
least 90 percent of the fair market value of the net assets and at least 
70 percent of the fair market value of the gross assets held by the 
acquired corporation immediately prior to the acquisition.
    (3) Average annual earnings. (i) The term average annual earnings 
referred to in subparagraph (2) of this paragraph is, for any 
corporation, the amount of its earnings and profits for any 3-year 
period ending with the last day of a taxable year of the issuing 
corporation in which it issues any obligation to provide consideration 
for an acquisition described in section 279(b)(1), computed without 
reduction for:
    (a) Interest paid or incurred,
    (b) Depreciation or amortization allowed under Chapter 1 of the 
Code,
    (c) Liability for tax under Chapter 1 of the Code, and
    (d) Distributions to which section 301(c)(1) apply (other than such 
distributions from the acquired corporation to the issuing corporation), 
and reduced to an annual average for such 3-year period. For the rules 
to determine the amount of earnings and profits of any corporation, see 
section 312 and the regulations thereunder.
    (ii) Except as provided for in subdivision (iii) of this 
subparagraph, for purposes of subdivision (i) of this subparagraph in 
the case of any corporation, the earnings and profits for such 3-year 
period shall be reduced to an annual average by dividing such earnings 
and profits by 36 and multiplying the quotient by 12. If a corporation 
was not in existence during the entire 36-month period as of the close 
of the taxable year referred to in subdivision (i) of this subparagraph, 
its average annual earnings shall be determined by dividing its earnings 
and profits for the period of its existence by the number of whole 
calendar months in such period and multiplying the quotient by 12.
    (iii) Where the issuing corporation acquires substantially all of 
the properties of an acquired corporation, the computation of earnings 
and profits of such acquired corporation shall be made for the period of 
such corporation beginning with the first day of the 3-year period of 
the issuing corporation and ending with the last day prior to the date 
on which substantially all of the properties were acquired. In 
determining the number of whole calendar months for such acquired 
corporation where the period for determining its earnings and profits 
includes 2 months which are not whole calendar months and the total 
number of days in such 2 fractional months exceeds 30 days, the number 
of whole calendar months for such period shall be increased by one. 
Where the number of days in the 2 fractional months total 30 days or 
less such fractional months shall be disregarded. After the number of 
whole calendar months is determined, the calculation for average annual 
earnings shall be made in the same manner as described in the last 
sentence of subdivision (ii) of this subparagraph.
    (e) Annual interest to be paid or incurred--(1) In general. For 
purposes of section 279(b)(4)(B), the term annual interest to be paid or 
incurred means:
    (i) If subdivision (ii) of this subparagraph does not apply, the 
annual interest to be paid or incurred by the issuing corporation only, 
for the taxable year beginning immediately after the day described in 
section 279(c)(1), determined by reference to its total indebtedness 
outstanding as of such day, or
    (ii) If projected earnings are determined under paragraph (d)(2)(ii) 
of this section, the annual interest to be paid or incurred by both the 
issuing corporation and the acquired corporation for 1 year beginning 
immediately after the day described in section 279(c)(1), determined by 
reference to their combined total indebtedness outstanding as of such 
day. However, where the issuing corporation acquires substantially all 
of the properties of the acquired corporation, the annual interest to be 
paid or incurred will be determined by reference to the total 
indebtedness outstanding of the issuing corporation only (including any 
indebtedness it assumed in the acquisition) as of the day described in 
section 279(c)(1).

The term annual interest to be paid or incurred refers to both actual 
interest and unstated interest. Such unstated interest includes original 
issue discount as defined in paragraph (a)(1) of Sec. 1.163-4 and 
amounts treated as interest under section 483. For purposes of

[[Page 655]]

this paragraph and paragraph (f) of this section (relating to the ratio 
of debt to equity), the indebtedness of any corporation shall be 
determined in accordance with generally accepted accounting principles. 
Thus, for example, the indebtedness of a corporation includes short-term 
liabilities, such as accounts payable to suppliers, as well as long-term 
indebtedness. Contingent liabilities, such as those arising out of 
discounted notes, the assignment of accounts receivable, or the 
guarantee of the liability of another, shall be included in the 
determination of the indebtedness of a corporation if the contingency is 
likely to become a reality. In addition, the indebtedness of a 
corporation includes obligations issued by the corporation, secured only 
by property of the corporation, and with respect to which the 
corporation is not personally liable. See section 279(g) and Sec. 
1.279-6 for rules with respect to the computation of annual interest to 
be paid or incurred in regard to members of an affiliated group of 
corporations.
    (2) Examples. The provisions of these paragraphs may be illustrated 
by the following examples:

    Example 1. Corporation X's earnings and profits calculated in 
accordance with section 279(c)(3)(B) for 1972, 1971, and 1970 
respectively were $29 million, $23 million, and $20 million. The 
interest to be paid or incurred during the calendar year of 1973 as 
determined by reference to the issuing corporation's total outstanding 
indebtedness as of December 31, 1972, was $10 million. By dividing the 
sum of the earnings and profits for the 3 years by 36 (the number of 
whole calendar months in the 3-year period) and multiplying the quotient 
by 12, the average annual earnings for X Corporation is $24 million. 
Since the projected earnings of X Corporation do not exceed by three 
times the annual interest to be paid or incurred (they exceed by only 
2.4 times), one of the circumstances described in section 279(b)(4) is 
present.
    Example 2. On March 1, 1972, W Corporation acquires substantially 
all of the properties of Z Corporation in exchange for W Corporation's 
bonds which satisfy the tests of section 279(b) (2) and (3). W 
Corporation files its income tax returns on the basis of fiscal years 
ending June 30. Z Corporation, which was formed on September 1, 1969, is 
a calendar year taxpayer. The earnings and profits of W Corporation for 
the last 3 fiscal years ending June 30, 1972, calculated in accordance 
with the provisions of section 279(c)(3)(B) were $300 million, $400 
million, and $380 million, respectively. The average annual earnings of 
W Corporation is $360 million ($1,080 million / 36x12). The earnings and 
profits of Z Corporation calculated in accordance with the provisions of 
section 279(c)(3)(B) were $4 million for the period of September 1, 1969 
to December 31, 1969, $10 million and $14 million for the calendar years 
of 1970 and 1971, respectively, and $2 million for the period of January 
1, 1972, through February 29, 1972, or a total of $30 million. To arrive 
at the average annual earnings, the sum of the earnings and profits, $30 
million, must be divided by 30 (the number of whole calendar months that 
Z Corporation was in existence during W Corporation's 3-year period 
ending with the day prior to the date substantially all the assets were 
acquired) and the quotient is multiplied by 12, which results in an 
average annual earnings of $12 million ($30 million/30x12) for Z 
Corporation. The combined average annual earnings of W Corporation and Z 
Corporation is $372 million. The interest for the fiscal year ending 
June 30, 1973, to be paid or incurred by W Corporation on its 
outstanding indebtedness as of June 30, 1972, is $110 million. Since the 
projected earnings exceed the annual interest to be paid or incurred by 
more than three times, the obligation will not be corporate acquisition 
indebtedness, unless the issuing corporation's debt to equity ratio 
exceeds 2 to 1.

    (f) Ratio of debt to equity--(1) In general. The condition described 
in section 279(b)(4)(A) is present if the ratio of debt to equity of the 
issuing corporation exceeds 2 to 1. Under section 279(c)(2), the term 
ratio of debt to equity means the ratio which the total indebtedness of 
the issuing corporation bears to the sum of its money and all its other 
assets (in an amount equal to adjusted basis for determining gain) less 
such total indebtedness. For the meaning of the term indebtedness, see 
paragraph (e)(1) of this section. See section 279(g) and Sec. 1.279-6 
for rules with respect to the computation of the ratio of debt to equity 
in regard to an affiliated group of corporations.
    (2) Examples. The provisions of section 279(b)(4)(A) and this 
paragraph may be illustrated by the following example:

[$5 million interest to be paid or incurred x $80 million owed to X Bank 
by its customers/$100 million total indebtedness]

    Example 1. On June 1, 1971, X Corporation, which files its federal 
income tax returns on a calendar year basis, issues an obligation

[[Page 656]]

for $45 million to the shareholders of Y Corporation to provide 
consideration for the acquisition of all of the stock of Y Corporation. 
Such obligation has the characteristics of corporate acquisition 
indebtedness described in section 279(b) (2) and (3). The projected 
earnings of X Corporation and Y Corporation exceed 3 times the annual 
interest to be paid or incurred by those corporations and, accordingly, 
the condition described in section 279(b)(4)(B) is not present. Also, on 
December 31, 1971, X Corporation has total assets with an adjusted basis 
of $150 million (including the newly acquired stock of Y Corporation 
having a basis of $45 million) and total indebtedness of $90 million. 
Hence, X Corporation's equity is $60 million computed by subtracting its 
$90 million of total indebtedness from its $150 million of total assets. 
Since X Corporation's ratio of debt to equity of 1.5 to 1 ($90 million 
of total indebtedness over $60 million equity) does not exceed 2 to 1, 
the condition described in section 279(b)(4)(A) is not present. 
Therefore, X Corporation's obligation for $45 million is not corporate 
acquisition indebtedness because on December 31, 1971, neither of the 
conditions specified in section 279(b)(4) existed.

    (g) Special rules for banks and lending or finance companies--(1) 
Debt to equity and projected earnings. Under section 279(c)(5), with 
respect to any corporation which is a bank (as defined in section 581) 
or is primarily engaged in a lending or finance business, the following 
rules are to be applied:
    (i) In determining under paragraph (f) of this section the ratio of 
debt to equity of such corporation (or of the affiliated group of which 
such corporation is a member), the total indebtedness of such 
corporation (and the assets of such corporation) shall be reduced by an 
amount equal to the total indebtedness owed to such corporation which 
arises out of the banking business of such corporation, or out of the 
lending or finance business of such corporation, as the case may be;
    (ii) In determining under paragraph (e) of this section the annual 
interest to be paid or incurred by such corporation (or by the issuing 
corporation and acquired corporation referred to in section 279(c)(4)(B) 
or by the affiliated group of corporations of which such corporation is 
a member), the amount of such interest (determined without regard to 
this subparagraph) shall be reduced by an amount which bears the same 
ratio to the amount of such interest as the amount of the reduction for 
the taxable year under subdivision (i) of this subparagraph bears to the 
total indebtedness of such corporation; and
    (iii) In determining under section 279(c)(3)(B) the average annual 
earnings, the amount of the earnings and profits for the 3-year period 
shall be reduced by the sum of the reductions under subdivision (ii) of 
this subparagraph for such period.

For purposes of this paragraph, the term lending or finance business 
means a business of making loans or purchasing or discounting accounts 
receivable, notes, or installment obligations. Additionally, the rules 
stated in this paragraph regarding the application of the ratio of debt 
to equity, the determination of the annual interest to be paid or 
incurred, and the determination of the average annual earnings also 
apply if the bank or lending or finance company is a member of an 
affiliated group of corporations. However, the rules are to be applied 
only for purposes of determining the debt, equity, projected earnings 
and annual interest of the bank or lending or finance company which then 
are taken into account in determining the debt to equity ratio and ratio 
of projected earnings to annual interest to be paid or incurred by the 
affiliated group as a whole. Thus, these rules are to be applied to 
reduce the bank's or lending or finance corporation's indebtedness, 
annual interest to be paid or incurred, and average annual earnings 
which are taken into account with respect to the group, but are not to 
reduce the indebtedness of, annual interest to be paid or incurred by, 
and average annual earnings of, any corporation in the affiliated group 
which is not a bank or a lending or finance company. In determining 
whether any corporation which is a member of an affiliated group is 
primarily engaged in a lending or finance business, only the activities 
of such corporation, and not those of the whole group, are to be taken 
into account. See Sec. 1.279-6 for the application of section 279 to 
certain affiliated groups of corporations.
    (2) Examples. The provisions of this paragraph may be illustrated by 
the following examples:

    Example 1. As of the close of the taxable year, X Bank has a total 
indebtedness of $100 million, total assets of $115 million, and $80

[[Page 657]]

million is owed to X Bank by its customers. Bank X's indebtedness is $20 
million ($100 million total indebtedness less $80 million owed to the X 
Bank by its customers) and its assets are $35 million ($115 million 
total assets less $80 million owed to the bank by its customers). If its 
annual interest to be paid or incurred is $5 million, such amount is 
reduced by $4 million. Thus, X Bank's annual interest to be paid or 
incurred is $1 million.
    Example 2. Assume the same facts as in Example 1. X Bank has 
earnings and profits of $23 million for the 3-year period used to 
determine projected earnings. In computing the average annual earnings, 
the $23 million amount will be reduced by $12 million (three times the 
$4 million reduction of interest in Example 1, assuming that the 
reduction was the same for each year). Thus X Bank's earnings and 
profits for such 3-year period are $11 million ($23 million total 
earnings and profits less $12 million reduction).

    (h) Statement to be attached to return. In any case where any 
corporation claims a deduction in excess of $5 million for interest paid 
or incurred during the taxable year on obligations issued to provide 
consideration for acquisitions described in section 279(b)(1) of stock 
in, or assets of, an acquired corporation, the corporation shall attach 
to its return for such taxable year a statement which includes the 
particular provisions of section 279 and, in sufficient detail, the 
facts establishing that such obligations were not corporate acquisition 
indebtedness, or that the amount of the deduction for interest on its 
corporate acquisition indebtedness did not exceed the amount of interest 
which may be deducted on such obligations under section 279(a).
