PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.187-1  Amortization of certain coal mine safety equipment.

    (a) Allowance of deduction--(1) In general. Under section 187(a), 
every person, at his election, shall be entitled to a deduction with 
respect to the amortization of the adjusted basis (for determining gain) 
of any certified coal mine safety equipment (as defined in Sec. 1.187-
2), based on a period of 60 months. Such 60-month period shall, at the 
election of the taxpayer, begin either with the month following the 
month in which such equipment was placed in service or with the 
succeeding taxable year. For rules as to making or discontinuing the 
election, see paragraphs (b) and (c) of this section. For the 
computation of the adjusted basis (for determining gain) of any 
certified coal mine safety equipment, see paragraph (b) of Sec. 1.187-
2.
    (2) Amount of deduction. (i) Such amortization deduction shall be an 
amount, with respect to each month of such 60-month period which falls 
within the taxable year, equal to the adjusted basis for determining 
gain of the certified coal mine safety equipment at the end of such 
month divided by the number of months (including the month for which the 
deduction is computed) remaining in such 60-month period. Such adjusted 
basis at the end of any month shall be computed without regard to the 
amortization deduction for such month. The total amortization deduction 
with respect to any certified coal mine safety equipment for a 
particular taxable year is the sum of the amortization deductions 
allowable for each month of the 60-month period which falls within such 
taxable year.
    (ii) If any certified coal mine safety equipment is sold or 
exchanged or otherwise disposed of during a particular month, then the 
amortization deduction (if any) allowable to the transferor in respect 
of that month shall be that portion of the amount to which such person 
would be entitled for a full month which the number of days in such 
month during which the equipment was held by such person bears to the 
total number of days in such month.
    (3) Effect on other deductions. (i) The amortization deduction 
provided by section 187(a) with respect to any month shall be in lieu of 
the depreciation deduction which would otherwise be allowable with 
respect to such equipment under section 167 for such month.
    (ii) If the adjusted basis of such coal mine safety equipment as 
computed

[[Page 252]]

under section 1011 for purposes other than the amortization deduction 
provided by section 187(a) is in excess of the adjusted basis, as 
computed under paragraph (b) of Sec. 1.187-2, then such excess shall be 
recovered through depreciation deductions under the rules of section 
167. See section 187(e), and paragraph (b)(2) of Sec. 1.187-2.
    (iii) See section 179 and paragraph (e)(1)(ii) of Sec. 1.179-1 for 
additional first-year depreciation in respect of certified coal mine 
safety equipment.
    (4) Special rules. (i) If the assets of a corporation which has 
elected to take the amortization deduction under section 187(a) are 
acquired by another corporation in a transaction to which section 381 
(relating to carryovers in certain corporate acquisitions) applies, the 
acquiring corporation is to be treated as if it were the transferor or 
distributor corporation for purposes of this section.
    (ii) For the right of estates and trusts to take the amortization 
deduction provided by section 187 see section 642(f) and Sec. 1.642(f)-
1.
    (iii) For the allowance of the amortization deduction in the case of 
coal mine safety equipment of partnerships see section 703 and Sec. 
1.703-1.
    (iv) In the case of certified coal mine safety equipment held by one 
person for life with the remainder to another person, the amortization 
deduction under section 187(a) shall be computed as if the life tenant 
were the absolute owner of the property and shall be allowable to the 
life tenant during his life.
    (5) Effective date. The provisions of this paragraph shall apply to 
taxable years ending after December 31, 1969.
    (6) Meaning of terms. Except as otherwise provided in Sec. 1.187-2, 
all terms used in section 187 and the regulations thereunder shall have 
the meaning provided by this section and Sec. 1.187-2.
    (b) Election of amortization--(1) In general. Under section 187(b), 
an election by the taxpayer to make amortization deductions with respect 
to any certified coal mine safety equipment and to begin the 60-month 
amortization period shall be made by a statement to that effect attached 
to his return for the taxable year in which falls the first month of the 
60-month amortization period so elected. Such statement shall include 
the following information:
    (i) A description clearly identifying each piece of certified coal 
mine safety equipment for which an amortization deduction is claimed;
    (ii) The date on which such equipment was ``placed in service'' (see 
paragraph (a)(2)(i) of Sec. 1.187-2);
    (iii) The date on which the amortization period began;
    (iv) The total costs paid or incurred in the acquisition and 
installation of such equipment;
    (v) A computation showing the adjusted basis (as defined in 
paragraph (b) of Sec. 1.187-2) of the equipment as of the beginning of 
the amortization period;
    (vi) In the case of electric face equipment which is newly acquired 
by the taxpayer, a statement that the equipment has been certified by 
the Secretary of the Interior or the Director of the Bureau of Mines as 
being permissible within the meaning of section 305(a)(2) of the Federal 
Coal Mine Health and Safety Act of 1969; and
    (vii) In the case of property placed in service in connection with 
used electric face equipment (within the meaning of paragraph (a)(2)(ii) 
of Sec. 1.187-2), a statement that such property has resulted in the 
used electric face equipment becoming permissible and a copy of the 
notification that such property is permissible.
    (2) Late certification. If, 90 days before the date on which the 
return described in this paragraph is due, a piece of coal mine safety 
equipment has not been certified as permissible by the Secretary of the 
Interior or the Director of the Bureau of Mines, then the election may 
be made by a statement in an amended income tax return for the taxable 
year in which falls the first month of the 60-month amortization period 
so elected. The statement and amended return in such case must be filed 
not later than 90 days after the date the equipment is certified as 
permissible by the Secretary of the Interior or the Director of the 
Bureau of Mines. Amended income tax returns or claims for credit or 
refund should also be filed at this time for other taxable years which 
are within the amortization period and which are subsequent to the 
taxable year for which the election is

[[Page 253]]

made. Nothing in this paragraph shall be construed as extending the time 
specified in section 6511 within which a claim for credit or refund may 
be filed.
    (3) Other requirements and considerations. No method of making the 
election provided for in section 187(a) other than that prescribed in 
this section shall be permitted on or after August 11, 1971. A taxpayer 
who does not elect in the manner prescribed in this section to take 
amortization deductions with respect to certified coal mine safety 
equipment shall not be entitled to such deductions. In the case of a 
taxpayer who has elected prior to August 11, 1971 the statement required 
by subparagraph (1) of this paragraph shall be attached to his income 
tax return for his taxable year in which August 11, 1971 occurs.
    (c) Election to discontinue or revoke amortization--(1) Election to 
discontinue. (i) Under section 187(c), if a taxpayer has elected to take 
the amortization deduction provided by section 187(a) with respect to 
any certified coal mine safety equipment, he may, after such election 
and prior to the expiration of the 60-month amortization period, elect 
to discontinue the amortization deduction for the remainder of the 60-
month period for such equipment.
    (ii) An election to discontinue the amortization deduction shall be 
made by a statement in writing filed with the District Director or with 
the director of the Internal Revenue Service center with whom the return 
of the taxpayer is required to be filed for its taxable year in which 
falls the first month for which the election terminates. In addition, a 
copy of such statement shall be attached to the taxpayer's income tax 
return filed for such taxable year. Such statement shall specify the 
month as of the beginning of which the taxpayer elects to discontinue 
such deductions, and shall be filed before the beginning of the month 
specified therein. In addition, such notice shall contain a description 
clearly identifying the certified coal mine safety equipment with 
respect to which the taxpayer elects to discontinue the amortization 
deduction. If the taxpayer so elects to discontinue the amortization 
deduction, he shall not be entitled to any further amortization 
deductions under section 187 with respect to such equipment.
    (2) Revocation of elections made prior to August 11, 1971. If before 
August 11, 1971 an election under section 187(a) has been made, consent 
is hereby given for the taxpayer to revoke such election without the 
consent of the Commissioner. Such election may be revoked by filing a 
notice of revocation on or before November 9, 1971. Such notice shall be 
in the form and shall be filed in the manner required by subparagraph 
(1)(ii) of this paragraph. If such revocation is for a period which 
falls within one or more taxable years for which an income tax return 
has been filed, an amended income tax return shall be filed for any 
taxable year in which a deduction was taken under section 187 on or 
before November 9, 1971.
    (3) Depreciation subsequent to discontinuance or in the case of 
revocation of amortization. (i) A taxpayer who elects in the manner 
prescribed under subparagraph (1) of this section to discontinue 
amortization deductions under section 187(a) or under subparagraph (2) 
of this paragraph to revoke an election made prior to August 11, 1971 
with respect to an item of certified coal mine safety equipment may be 
entitled to a deduction for depreciation with respect to such equipment. 
See section 167 and the regulations thereunder.
    (ii) In the case of an election to discontinue an amortization 
deduction under section 187, the deduction for depreciation shall be 
computed beginning with the first month as to which such amortization 
deduction is not applicable, and shall be based upon the adjusted basis 
(see section 1011 and the regulations thereunder) of the property as of 
the beginning of such month. Such depreciation deduction shall be based 
upon the remaining portion of the period authorized under section 167 
for the facility, as determined as of the first day of the first month 
as of which the amortization deduction is not applicable.
    (iii) In the case of a revocation of an election under section 187 
referred to in paragraph (c)(2) of this section the deduction for 
depreciation shall begin as of the time such depreciation deduction 
would have been taken but for the

[[Page 254]]

election under section 187. See subparagraph (2) of this section for 
rules as to filing amended returns for years for which amortization 
deductions have been taken.
    (d) Examples. This section may be illustrated by the following 
examples:

    Example 1. On September 30, 1970, the X Corporation, which uses the 
calendar year as its taxable year, places in service a piece of coal 
mine safety equipment required as a result of the Federal Coal Mine 
Health and Safety Act of 1969 which is certified as indicated in 
paragraph (a) of Sec. 1.187-2. The cost of the equipment is $120,000. 
On its income tax return filed for 1970, the corporation elects to take 
the amortization deductions allowed by section 187(a) with respect to 
the equipment and to begin the 60-month amortization period with October 
1970, the month following the month in which it was placed in service. 
The adjusted basis at the end of October 1970 (determined without regard 
to the amortization deduction allowed by section 187(a) for that month) 
is $120,000. The allowable amortization deduction with respect to such 
equipment for the taxable year 1970 is $6,000, computed as follows:

Monthly amortization deductions:
  October: $120,000 divided by 60............................     $2,000
  November: $118,000 ($120,000 minus $2,000) divided by 59...      2,000
  December: $116,000 ($118,000 minus $2,000) divided by 58...      2,000
                                                              ----------
    Total amortization deduction for 1970....................      6,000


    Example 2. Assume the same facts as in Example 1. Assume further 
that on May 20, 1972, X properly files notice of its election to 
discontinue the amortization deductions with the month of June 1972. The 
adjusted basis of the equipment as of June 1, 1972 (assuming no capital 
additions or improvements) is $80,000, computed as follows: Yearly 
amortization deductions computed in accordance with Example 1:

1970.........................................................     $6,000
1971.........................................................     24,000
1972 (for the first 5 months)................................     10,000
                                                              ----------
    Total amortization deductions for 20 months..............     40,000
                                                              ==========
Adjusted basis at beginning of amortization period...........    120,000
  Less: Amortization deductions..............................     40,000
                                                              ----------
Adjusted basis as of June 1, 1972............................     80,000



Beginning as of June 1, 1972, the deduction for depreciation under 
section 167 is allowable with respect to the property on its adjusted 
basis of $80,000.
    Example 3. Assume the same facts as in Example 1, except that on its 
income tax return filed in 1970, X does not elect to take amortization 
deductions allowed by section 187(a) but that on its income tax return 
filed for 1971 X elects to begin the amortization period as of January 
1, 1971, the taxable year succeeding the taxable year the equipment was 
placed in service. Assume further that the only adjustment to basis for 
the period October 1, 1970, to January 1, 1971, is $3,000 for 
depreciation (the amount allowable, of which $2,000 is for additional 
first year depreciation under section 179) for the last 3 months of 
1970. The adjusted basis (for determining gain) for purposes of section 
187 as of that date is $120,000 less $3,000 or $117,000.
