                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.167(a)-12  Depreciation based on class lives for property first 
placed in service before January 1, 1971.

    (a) In general--(1) Summary. This section provides an elective class 
life system for determining the reasonable allowance for depreciation of 
certain classes of assets for taxable years ending after December 31, 
1970. The system applies only to assets placed in service before January 
1, 1971. Depreciation for such assets during periods prior to January 1, 
1971, may have been determined in accordance with Revenue Procedure 62-
21. Accordingly, rules are provided which permit taxpayers to apply the 
system in taxable years ending after December 31, 1970, to such assets 
without the necessity of changing or regrouping their depreciation 
accounts other than as previously required by Revenue Procedure 62-21. 
The system is designed to minimize disputes between taxpayers and the 
Internal Revenue Service as to the useful life of assets, salvage value, 
and repairs. See Sec. 1.167(a)-11 for a similar system for property 
placed in service after December 31, 1970. See paragraph (d)(2) of Sec. 
1.167(a)-11 for treatment of expenditures for the repair, maintenance, 
rehabilitation or improvement of certain property. The system provided 
by this section is optional with the taxpayer. An election under this 
section applies only to qualified property in an asset guideline class 
for which an election is made and only for the taxable year of election. 
The taxpayer's election is made with the income tax return for the 
taxable year. This section also revokes the reserve ratio test for 
taxable years ending after December 31, 1970, and provides transitional 
rules for taxpayers who after January 11, 1971, adopt Revenue Procedure 
62-21 for a taxable year ending prior to January 1, 1971.
    (2) Revocation of reserve ratio test and other matters. Except as 
otherwise expressly provided in this section and in paragraph (b)(5)(vi) 
of Sec. 1.167(a)-11, the provisions of Revenue Procedure 62-21 shall 
not apply to any property for any taxable year ending after December 31, 
1970, whether or not the taxpayer elects to apply this section to any 
property. See paragraph (f) of this section for rules for the adoption 
of Revenue Procedure 62-21 for taxable years ending prior to January 1, 
1971.
    (3) Definition of qualified property. The term ``qualified 
property'' means tangible property which is subject to the allowance for 
depreciation provided by section 167(a), but only if--
    (i) An asset guideline class and asset guideline period are in 
effect for such property for the taxable year, and
    (ii) The property is first placed in service by the taxpayer before 
January 1, 1971,
    (iii) The property is placed in service before January 1, 1971, but 
first placed in service by the taxpayer after December 31, 1970, and is 
not includible in an election under Sec. 1.167(a)-11 by reason of Sec. 
1.167(a)-11(b)(7) (property acquired as a result of a mere change in 
form) or Sec. 1.167(a)-11(e)(3)(i) (certain property acquired in a 
transaction to which section 381(a) applies), or

[[Page 976]]

    (iv) The property is acquired and first placed in service by the 
taxpayer after December 31, 1970, pursuant to a binding written contract 
entered into prior to January 1, 1971, and is excluded in accordance 
with paragraph (b)(5)(iv) of Sec. 1.167(a)-11 from an election to apply 
Sec. 1.167(a)-11.

The provisions of paragraph (e)(1) of Sec. 1.167(a)-11 apply in 
determining whether property is first placed in service before January 
1, 1971. See subparagraph (4)(ii) of this paragraph for special rules 
for the exclusion of property from the definition of qualified property.
    (4) Requirements of election--(i) In general. An election to apply 
this section to qualified property must be made within the time and in 
the manner specified in paragraph (e) of this section. The election must 
specify that the taxpayer consents to and agrees to apply all the 
provisions of this section. The election may be made separately for each 
asset guideline class. Thus, a taxpayer may for the taxable year elect 
to apply this section to one, more than one, or all asset guideline 
classes in which he has qualified property. An election to apply this 
section for a taxable year must include all qualified property in the 
asset guideline class for which the election is made.
    (ii) Special rules for exclusion of property from application of 
this section. (a) If for the taxable year of election, the taxpayer 
computes depreciation under section 167(k) or computes amortization 
under sections 169, 185, 187, 188, or paragraph (b) of Sec. 1.162-11 
with respect to property, such property is not qualified property for 
such taxable year. If for the taxable year of election, the taxpayer 
computes depreciation under any method of depreciation (other than a 
method described in the preceding sentence) not permitted by 
subparagraph (5)(v) of this paragraph for any property in an asset 
guideline class (other than subsidiary assets excluded from an election 
under (b) of this subdivision), no property in such asset guideline 
class is qualified property for such taxable year.
    (b) The taxpayer may exclude from an election to apply this section 
all (but not less than all) subsidiary assets. Subsidiary assets so 
excluded are not qualified property for such taxable year. For purposes 
of this subdivision the term ``subsidiary assets'' includes jigs, dies, 
molds, returnable containers, glassware, silverware, textile mill cam 
assemblies, and other equipment includable in Group One, Class 5, of 
Revenue Procedure 62-21 which is usually and properly accounted for 
separately from other property and under a method of depreciation not 
expressed in terms of years.
    (iii) Special rule for certain public utility property. (a) In the 
case of public utility property described in section 167(1)(3)(A)(iii) 
for which no guideline life was prescribed in Revenue Procedure 62-21 
(or for which reference was made in Revenue Procedure 62-21 to lives or 
rates established by governmental regulatory agencies) of a taxpayer 
which--
    (1) Is entitled to use a method of depreciation other than a 
``subsection (1) method'' of depreciation (as defined in section 
167(1)(3)(F)) only if it uses the ``normalization method of accounting'' 
(as defined in section 167(1)(3)(G)) with respect to such property, or
    (2) Is entitled for the taxable year to use only a ``subsection (1) 
method'' of depreciation,

such property shall be qualified property (as defined in subparagraph 
(3) of this paragraph) only if the taxpayer normalizes the tax deferral 
resulting from the election to apply this section.
    (b) The taxpayer will be considered to normalize the tax deferral 
resulting from the election to apply this section only if it computes 
its tax expense for purposes of establishing its cost of service for 
ratemaking purposes and for reflecting operating results in its 
regulated books of account using a period for depreciation no less than 
the period used for computing its depreciation expense for ratemaking 
purposes and for reflecting operating results in its regulated books of 
account for the taxable year, and the taxpayer makes adjustments to a 
reserve to reflect the deferralof taxes resulting from the use of a 
period for depreciation under section 167 in accordance with an election 
to apply this section different from the period used for computing its 
depreciation expense for ratemaking purposes and for reflecting 
operating results in

[[Page 977]]

its regulated books of account for the taxable year. A determination 
whether the taxpayer is considered to normalize under this subdivision 
the tax deferral resulting from the election to apply this section shall 
be made in a manner consistent with the principles for determining 
whether a taxpayer is using the ``normalization method of accounting'' 
(within the meaning of section 167(1)(3)(G)). See Sec. 1.167(l)-1(h).
    (c) If a taxpayer, which has elected to apply this section to any 
qualified public utility property and is required under (a) of this 
subdivision to normalize the tax deferral resulting from the election to 
apply this section to such property, fails to normalize such tax 
deferral, the election to apply this section to such property shall 
terminate as of the beginning of the taxable year for which the taxpayer 
fails to normalize such tax deferral. Application of this section to 
such property for any period prior to the termination date will not be 
affected by this termination.
    (5) Determination of reasonable allowance for depreciation--(i) In 
general. The allowance for depreciation of qualified property to which 
the taxpayer elects to apply this section shall be determined in 
accordance with this section. The annual allowance for depreciation is 
determined by using the method of depreciation adopted by the taxpayer 
and a rate based upon a life permitted by this section. In the case of 
the straight-line method of depreciation, the rate of depreciation shall 
be based upon the class life (or individual life if the taxpayer assigns 
individual depreciable lives in accordance with subdivision (iii) of 
this subparagraph) used by the taxpayer with respect to the assets in 
the asset guideline class. Such rate will be applied to the unadjusted 
basis of the asset guideline class (individual assets or depreciation 
accounts if the taxpayer assigns individual depreciable lives). In the 
case of the sum of the years-digits method of depreciation, the rate of 
depreciation will be determined based upon the remaining life of the 
class (or individual remaining lives if the taxpayer assigns such lives 
in accordance with subdivision (iii) of this subparagraph) and is 
applied to the adjusted basis of the class (or individual accounts or 
assets) as of the beginning of the taxable year of election. The 
remaining life of a depreciation account is determined by dividing the 
unrecovered cost or other basis of the account, as computed by straight-
line depreciation, by the gross cost or unadjusted basis of the account, 
and multiplying the result by the class life used with respect to the 
account. In the case of the declining balance method of depreciation, 
the rate of depreciation for the asset guideline class shall be based 
upon the class life (or individual life if the taxpayer assigns such 
lives in accordance with subdivision (iii) of this subparagraph). Such 
rate is applied to the adjusted basis of the class (or individual 
accounts or assets) as of the beginning of the taxable year of election.
    (ii) Reasonable allowance by reference to class lives. The amount of 
depreciation for all qualified property in an asset guideline class to 
which the taxpayer elects to apply this section will constitute the 
reasonable allowance provided by section 167(a) and the depreciation for 
the asset guideline class will not be adjusted if--
    (a) The taxpayer's qualified property is accounted for in one or 
more depreciation accounts which conform to the asset guideline class, 
and the depreciation for each such account is determined by using a rate 
based upon a life not less than the class life, or
    (b) The taxpayer's qualified property is accounted for in one or 
more depreciation accounts (whether or not conforming to the asset 
guideline class) for which depreciation is determined at a rate based 
upon the taxpayer's estimate of the lives of the assets (instead of the 
class life) and the total amount of depreciation so determined for the 
asset guideline class for the taxable year of election is not more than 
would be permitted under (a) of this subdivision for such year using the 
method of depreciation adopted by the taxpayer for the property.

See subdivision (vii) of this subparagraph for determination of 
reasonable allowance if depreciation exceeds the amount permitted by 
this subdivision. See paragraph (b) of this section for rules regarding 
the determination of ``class life''. For rules for regrouping

[[Page 978]]

depreciation accounts to conform to the asset guideline class, see 
subdivision (iv) of this subparagraph.
    (iii) Consistency when individual lives are used. If the taxpayer 
assigns individual depreciable lives to assets in accordance with 
subdivision (ii)(b) of this subparagraph, even though the total amount 
of depreciation for the asset guideline class will not be adjusted, the 
lives assigned to the various assets in the asset guideline class must 
be reasonably in proportion to their relative expected periods of use in 
the taxpayer's business. Thus, although the taxpayer who uses individual 
asset lives normally has latitude in thereby allocating the depreciation 
for the asset guideline class among the assets, if the lives are grossly 
disproportionate (as where a short life is assigned to one asset and a 
long life to another even though the expected periods of use are the 
same), the taxpayer's allocation of depreciation to particular assets or 
depreciation accounts may be adjusted. For example, the taxpayer's 
allocation may be adjusted for purposes of determining adjusted basis 
under section 1016(a) or in allocating depreciation to the 50-percent 
limitation on percentage depletion provided by section 613(a). See 
paragraph (d) of this section for rules regarding the use of individual 
asset lives for purposes of classifying retirements as normal or 
abnormal.
    (iv) Regrouping depreciation accounts. Without the consent of the 
Commissioner, the taxpayer may for any taxable year for which he elects 
to apply this section to an asset guideline class, regroup his accounts 
for that and all succeeding taxable years to conform to the asset 
guideline class. Other changes in accounting, including a change from 
item accounts to multiple-asset accounting, may be made with the consent 
of the Commissioner. No depreciation accounts for which the straight 
line or sum of the years-digits method of depreciation is adopted may be 
combined under this section which would not be permitted to be combined 
under part III of Revenue Procedure 65-13, as in effect on January 1, 
1971. Accordingly, whether or not the taxpayer adopted the guideline 
system of Revenue Procedure 62-21 for a taxable year to which part III 
of Revenue Procedure 65-13 is applicable, the depreciation allowance for 
any taxable year of election under this section may not exceed that 
amount which would have been allowed for such year if the taxpayer had 
used item accounts or year of acquisition accounts. Thus, for example, 
if a calendar year taxpayer acquired a $90 asset on the first day of 
each year from 1966 through 1970, placed such assets in a single 
multiple asset account, adopted the sum of the years-digits method of 
depreciation and used a 5-year depreciable life for such assets, and in 
1971 uses the 5-year class life determined under paragraph (b) of this 
section, the depreciation allowance for such assets in 1971 under this 
section may not exceed $60, that is, the amount which would be allowed 
if the taxpayer had used year of acquisition accounts for the assets for 
the years 1966 through 1970.

For purposes of this subparagraph, a taxpayer's depreciation accounts 
conform to the asset guideline class if each depreciation account 
includes only assets of the same asset guideline class.
    (v) Method of depreciation. The same method of depreciation must be 
applied to all property in a single depreciation account. The method of 
depreciation is subject to the limitations of section 167 (c), (j), and 
(l). Except as otherwise provided in this subdivision, the taxpayer must 
apply a method of depreciation described in section 167(b) (1), (2), or 
(3) for qualified property to which the taxpayer elects to apply this 
section. A method of depreciation permitted under section 167(b)(4) may 
be used under this section if the method was used by the taxpayer with 
respect to the property for his last taxable year ending before January 
1, 1971, the method is expressed in terms of years, the taxpayer 
establishes to the satisfaction of the Commissioner that the method is 
both a reasonable and consistent method, and if the taxpayer applies 
paragraph (b)(2) of this section (relating to class lives in special 
situations) to determine a classlife, that the method of determining 
such class life is consistent with the principles of Revenue Procedure 
62-21 as applied to

[[Page 979]]

such a method. If the taxpayer has applied a method of depreciation with 
respect to the property which is not described in section 167(b) (1), 
(2), (3), or (4) (as permitted under the preceding sentence), he must 
change under this section to a method of depreciation described in 
section 167(b) (1), (2), or (3) for the first taxable year for which an 
election is made under this section. Other changes in depreciation 
method may be made with the consent of the Commissioner (see sec. 446 
and the regulations thereunder). (See also sec. 167(e).)
    (vi) Salvage value. In applying the method of depreciation adopted 
by the taxpayer, the annual allowance for depreciation is determined 
without adjustment for the salvage value of the property, except that no 
depreciation account may be depreciated below a reasonable salvage value 
for the account. See paragraph (c) of this section for definition and 
treatment of salvage value.
    (vii) Reasonable allowance when depreciation exceeds amount based on 
class life. In the event that the total amount of depreciation claimed 
by the taxpayer on his income tax return, in a claim for refund, or 
otherwise, for an asset guideline class with respect to which an 
election is made under this section for the taxable year, exceeds the 
maximum amount permitted under subdivision (ii)(a) of this 
subparagraph--
    (a) If the excess is established to the satisfaction of the 
Commissioner to be the result of a good faith mistake by the taxpayer in 
determining the maximum amount permitted under subdivision (ii) (a) of 
this subparagraph, the taxpayer's election to apply this section will be 
treated as valid and only such excess will be disallowed, and
    (b) In all other cases, the taxpayer's election to apply this 
section to the asset guideline class for the taxable year is invalid and 
the reasonable allowance for depreciation will be determined without 
regard to this section. (See Sec. 1.167(a)-1 (b) for rules regarding 
the estimated useful life of property.)
    (b) Determination of class lives--(1) Class lives in general. The 
class life determined under this paragraph (without regard to any range 
or variance permitted with respect to class lives under Sec. 1.167(a)-
11) will be applied for purposes of determining whether the allowance 
for depreciation for qualified property included in an election under 
this section is subject to adjustment. The taxpayer is not required to 
use the class life determined under this paragraph for purposes of 
determining the allowance for depreciation. Except as provided in 
subparagraph (2) of this paragraph, the class life of qualified property 
to which the taxpayer elects to apply this section is the shorter of--
    (i) The asset guideline period for the asset guideline class as set 
forth in Revenue Procedure 72-10 as in effect on March 1, 1972 (applied 
without regard to any special provision therein with respect to property 
predominantly used outside the United States), or
    (ii) The asset guideline period for the asset guideline class as set 
forth in any supplement or revision of Revenue Procedure 72-10, but only 
if and to the extent by express reference in such supplement or revision 
made applicable for the purpose of changing the asset guideline period 
or classification of qualified property to which this section applies.

See paragraph (e)(3)(iii) of this section for requirement that the 
election for the taxable year specify the class life for each asset 
guideline class. Generally, the applicable asset guideline class and 
asset guideline period for qualified property to which the taxpayer has 
elected to apply this section will not be changed for the taxable year 
of election to reflect any supplement or revision thereof after the 
taxable year. However, if expressly provided in such a supplement or 
revision, the taxpayer may, at his option in the manner specified 
therein, apply the revised or supplemented asset guideline classes or 
periods to such property for such taxable year and succeeding taxable 
years. The principles of this subparagraph may be illustrated by the 
following example:

    Example. (i) Corporation X, a calendar year taxpayer, has assets in 
asset guideline class 20.4 of Revenue Procedure 72-10 which were placed 
in service by corporation X in 1967, 1968, and 1970. Corporation X also 
has assets in asset guideline class 22.1 of Revenue Procedure 72-10 
which were placed in service at various times prior to 1971. Corporation 
X has no other qualified property. Corporation

[[Page 980]]

X elects to apply this section for 1971 to both classes. Assume that the 
class lives are determined under this subparagraph and not under 
subparagraph (2) of this paragraph.
    (ii) The class lives for asset guideline classes 20.4 and 22.1 are 
their respective asset guideline periods of 12 years and 9 years in 
Revenue Procedure 72-10.
    (iii) Accordingly, in the election for the taxable year, in 
accordance with paragraph (e)(3)(iii) of this section, corporation X 
specifies a class life of 12 years for asset guideline class 20.4 and a 
class life of 9 years for asset guideline class 22.1

    (2) Class lives in special situations. Notwithstanding subparagraph 
(1) of this paragraph, for the purposes of this section the class life 
for the asset guideline class determined under this subparagraph shall 
be used if such class life is shorter than the class life determined 
under subparagraph (1) of this paragraph. If property described in 
paragraph (a)(2)(iii) of this section in an asset guideline class is 
acquired by the taxpayer in a transaction to which section 381(a) 
applies, for purposes of this subparagraph such property shall be 
segregated from other property in the class and treated as in a separate 
asset guideline class, and the class life for that asset guideline class 
under this subparagraph shall be the shortest class life the transferor 
was entitled to use under this section for such property on the date of 
such transfer. In all other cases, the class life for the asset 
guideline class for purposes of this subparagraph shall be the shortest 
class life (within the meaning of sec. 4, part II, of Revenue Procedure 
62-21) which can be justified by application of secs. 3.02(a), 3.03(a), 
or 3.05, part II, of Revenue Procedure 62-21 (other than the portion of 
such sec. 3.05 dealing with justification of a class life by reference 
to facts and circumstances) for the taxpayer's last taxable year ending 
prior to January 1, 1971.

A class life justified by application of section 3.03(a), Part II, of 
Revenue Procedure 62-21 shall not be shorter than can be justified under 
the Adjustment Table for Class Lives in Part III of such Revenue 
Procedure. For purposes of this subparagraph and paragraph (f)(1)(iii) 
of this section, the reserve ratio test is met only if the taxpayer's 
reserve ratio does not exceed the upper limit of the appropriate reserve 
ratio range or in the alternative during the transitional period there 
provided does not exceed the appropriate ``transitional upper limit'' in 
section 3, Part II, of Revenue Procedure 65-13. References to Revenue 
Procedure 62-21 include all morifications, amendments, and supplements 
thereto as of January 1, 1971. The guideline form of the reserve ratio 
test, as described in Revenue Procedure 65-13, may be applied for 
purposes of this subparagraph in a manner consistent with the rules 
contained in section 7, Part II, of Revenue Procedure 65-13 and sections 
3.02, 3.03, and 3.05, Part II, of Revenue Procedure 62-21. The 
principles of this subparagraph may be illustrated by the following 
examples:

    Example (1). Corporation X, a calendar year taxpayer, has all its 
assets in asset guideline class 20.4 of Revenue Procedure 72-10 which 
were placed in service by corporation X prior to 1971. Corporation X 
elects to apply this section for 1971. For taxable years 1967 through 
1969, corporation X had used a class life (within the meaning of section 
4, Part II, of Revenue Procedure 62-21) for asset guideline class 20.4 
of 12 years. The asset guideline period in Revenue Procedure 72-10 in 
effect for 1971 is also 12 years. Assume that for 1969 corporation X's 
reserve ratio was below the appropriate reserve ratio lower limit. 
However, corporation X could not justify a class life shorter than the 
asset guideline period of 12 years for 1970 since corporation X had not 
used the 12-year class life for a period at least equal to one-half of 
12 years. (See section 3.03(a), Part II, of Revenue Procedure 62-21.) 
Accordingly, the class life for asset guideline class 20.4 in 1971 is 
the asset guideline period of 12 years in accordance with subparagraph 
(1) of this paragraph.
    Example (2). The facts are the same as in example (1) except that 
corporation X had used a class life of 10 years for guideline class 20.4 
since 1967. Corporation X had not used the class life of 10 years for a 
period at least equal to one-half of 10 years. However, in 1968 
corporation X's 10-year class life was accepted on audit by the Internal 
Revenue Service and corporation X met the reserve ratio test in 1970 for 
guideline class 20.4 using a test life of 10 years. (See section 3.05, 
Part II, of Revenue Procedure 62-21.) Accordingly, the class life of 10 
years is justified for 1970 and the class life for 1971 is 10 years in 
accordance with this subparagraph. If the taxpayer's class life had not 
been audited and accepted for 1968, and in the absence of other 
circumstances, the taxpayer could not justify a class life shorter than 
the asset guideline period of 12 years since it had not used the 10-year 
class life for a period at

[[Page 981]]

least equal to one-half of 10 years. (See section 3.02, Part II, of 
Revenue Procedure 62-21.)
    Example (3). Corporation Y, a calendar year taxpayer, has all its 
assets in asset guideline class 13.3 of Revenue Procedure 72-10 which 
were placed in service from 1960 through 1970. Corporation Y elects to 
apply this section for 1971. The asset guideline period in Revenue 
Procedure 72-10 in effect for 1971 is 16 years. Since 1963 corporation Y 
had used a class life of 16 years for asset guideline 13.3. At the end 
of 1969 corporation Y's reserve ratio for guideline class 13.3 was 36 
percent. With a growth rate of 8 percent and a test life of 16 years the 
appropriate reserve ratio lower limit was 37 percent. Corporation Y's 
reserve ratio of 36 percent was below the lower limit of the appropriate 
reserve ratio range. Corporation Y had used the 16-year class life for 
at least eight years. A class life of 13.5 years for 1970 was justified 
by application of section 3.03(a), Part II, of Revenue Procedure 62-21 
and the Adjustment Table for Class Lives in Part III, of Revenue 
Procedure 62-21. The class life for 1971 is 13.5 years in accordance 
with this subparagraph.

    (3) Classification of property--(i) In general. Property to which 
this section applies shall be included in the asset guideline class for 
the activity in which the property is primarily used in the taxable year 
of election. See paragraph (d)(5) of this section for rule regarding the 
classification of leased property.
    (ii) Insubstantial activity. The provisions of Revenue Produce 62-21 
with respect to classification of assets used in an activity which is 
insubstantial may be applied under this section.
    (iii) Special rule for certain public utilities. An electric or gas 
utility which in accordance with Revenue Procedure 64-21 used a 
composite guideline class basis for applying Revenue Procedure 62-21 for 
its last taxable year prior to January 1, 1971, may apply Revenue 
Procedure 72-10 and this section on the basis of such composite asset 
guideline class determined as provided in Revenue Procedure 64-21. For 
the purposes of this section all property in the composite guideline 
class shall be treated as included in a single asset guideline class.
    (c) Salvage value--(1) In general-- (i) Definition of gross salvage 
value. ``Gross salvage'' value is the amount (determined at or as of the 
time of acquisition but without regard to the application of Revenue 
Procedure 62-21) which is estimated will be realized upon a sale or 
other disposition of qualified property when it is no longer useful in 
the taxpayer's trade or business or in the production of his income and 
is to be retired from service, without reduction for the cost of 
removal, dismantling, demolition, or similar operations. ``Net salvage'' 
is gross salvage reduced by the cost of removal, dismantling, 
demolition, or similar operations. If a taxpayer customarily sells or 
otherwise disposes of property at a time when such property is still in 
good operating condition, the gross salvage value of such property is 
the amount expected to be realized upon such sale or disposition, and 
under certain circumstances, as where such property is customarily sold 
at a time when it is still relatively new, the gross salvage value may 
constitute a relatively large proportion of the unadjusted basis of such 
property.
    (ii) Definition of salvage value. ``Salvage value'' for purposes of 
this section means gross or net salvage value less the amount, if any, 
by which reduced by application of section 167(f). Generally, as 
provided in section 167(f), a taxpayer may reduce the gross or net 
salvage value for an account by an amount which does not exceed 10 
percent of the unadjusted basis of the personal property (as defined in 
section 167(f)(2)) in the account.
    (2) Estimation of salvage value--(i) In general. For the first 
taxable year for which he elects to apply this section, the taxpayer 
must (in accordance with paragraph (e)(3)(iv)(c) of this section) 
establish salvage value for all qualified property to which the election 
applies. The taxpayer may (in accordance with subparagraph (1) of this 
paragraph) determine either gross or net salvage, but an election under 
this section does not constitute permission to change the manner of 
estimating salvage. Permission to change the manner of estimating 
salvage must be obtained by filing form 3115 with the Commissioner of 
Internal Revenue, Washington, D.C. 20224, within the time otherwise 
permitted for thetaxable year or before September 6, 1973. Salvage value 
in succeeding taxable years of election will be determined by 
adjustments of such initial salvage value for the account, as

[[Page 982]]

retirements occur. This salvage value established by the taxpayer for 
the first taxable year of election will not be redetermined merely as a 
result of fluctuations in price levels or as a result of other 
circumstances occurring after the close of such taxable year. See 
paragraph (e)(3)(iv) of this section for requirements that the taxpayer 
specify in his election the aggregate amount of salvage value for an 
asset guideline class and that the taxpayer maintain records reasonably 
sufficient to identify the salvage value established for each 
depreciation account in the class.
    (ii) Salvage as limitation on depreciation. In no case may an 
account be depreciated under this section below a reasonable salvage 
value, after taking into account any reduction in gross or net salvage 
value permitted by section 167(f). For example, if the salvage value of 
an account for 1971 is $75, the unadjusted basis of the account is $500, 
and the depreciation reserve is $425, no depreciation is allowable for 
1971.
    (iii) Special rule for first taxable year. If for a taxable year 
ending prior to January 1, 1971, the taxpayer had adopted Revenue 
Procedure 62-21 prior to January 12, 1971 (see paragraph (f)(2) of this 
section), no adjustment in the amount of depreciation allowable for any 
taxable year ending prior to January 1, 1971, shall be made solely by 
reason of establishing salvage value under this paragraph for any 
taxable year ending after December 31, 1970. The principles of this 
subdivision may be illustrated by the following example:

    Example. Taxpayer A had adopted Revenue Procedure 62-21 prior to 
January 12, 1971, for taxable years prior to 1971. Taxpayer A had not 
taken into account any salvage value for account No. 1 which is one of 
four depreciation accounts A has in the class. The reserve ratio test 
has been met for all years prior to 1971 and in accordance with Revenue 
Procedure 62-21 no adjustments in depreciable lives or salvage values 
were made. At the end of A's taxable year 1970, the unadjusted basis of 
account No. 1 was $10,000 and the reserve for depreciation was $9,800. 
Pursuant to this paragraph, A establishes a salvage value of $400 for 
account No. 1 (determined at or as of the time of acquisition). This 
salvage value is determined to be correct. No depreciation is allowable 
for account No. 1 in 1971. No depreciation is disallowed for any taxable 
year prior to 1971, solely by reason of establishing salvage value under 
this paragraph.

    (3) Limitation on adjustment of reasonable salvage value. The 
salvage value established by the taxpayer for a depreciation account 
will not be redetermined if it is reasonable. Since the determination of 
salvage value is a matter of estimation, minimal adjustments will not be 
made. The salvage value established by the taxpayer will be deemed to be 
reasonable unless there is sufficient basis for a determination of an 
amount of salvage value for the account which exceeds the salvage value 
established by the taxpayer for the account by an amount greater than 10 
percent of the unadjusted basis of the account at the close of such 
taxable year. If the salvage value established by the taxpayer for the 
account is not within the 10-percent range or if the taxpayer follows 
the practice of understating his estimates of salvage to take advantage 
of this subdivision, and if there is a determination of an amount of 
salvage value for the account for the taxable year which exceeds the 
salvage value established by the taxpayer for the account for such 
taxable year, an adjustment will be made by increasing the salvage value 
established by the taxpayer for the account by an amount equal to the 
difference between the salvage value as determined and the salvage value 
established by the taxpayer for the account. For the purposes of this 
subdivision, a determination of salvage value shall include all 
determinations at all levels of audit and appellate proceedings, and as 
well as all final determinations within the meaning of section 
1313(a)(1). This subparagraph shall apply to each such determination.
    (4) Examples. The principles of this paragraph may be illustrated by 
the following examples in which it is assumed that the taxpayer has 
established salvage value in accordance with this paragraph and has not 
followed a practice of understating his estimates of salvage value:

    Example (1). Taxpayer B elects to apply this section for 1971. 
Assets Y and Z are the only assets in a multiple asset account of 1967, 
the year in which the assets were acquired. The unadjusted basis of 
asset Y is $50,000 and the unadjusted basis of asset Z is

[[Page 983]]

$30,000. B estimated a gross salvage value of $55,000 at the time of 
acquisition. The property qualified under section 167(f)(2) and B 
reduced the amount of salvage taken into account by $8,000 (that is, 10 
percent of $80,000, under sec. 167(f)). Thus, in accordance with this 
paragraph and paragraph (e)(3)(iv)(c) of this section, B establishes a 
salvage value of $47,000 for the account for 1971. Assume that there is 
not sufficient basis for determining a salvage value for the account 
greater $52,000 (that is $60,000 minus the $8,000 reduction under sec. 
167(f)). Since the salvage value of $47,000 established by B for the 
account is within the 10 percent range, it is reasonable. Salvage for 
the account will not be redetermined.
    Example (2). The facts are the same as in example (1) except that B 
estimated a gross salvage value of $50,000 and establishes a salvage 
value of $42,000 for the account (that is, $50,000 minus the $8,000 
reduction under section 167(f)). There is sufficient basis for 
determining an amount of salvage value greater than $50,000 (that is, 
$58,000 minus the $8,000 reduction under section 167(f)). The salvage 
value of $42,000 established by B for the account can be redetermined 
without regard to the limitation in subparagraph (3) of this paragraph, 
since it is not within the 10 percent range. Upon audit of B's tax 
return for 1971 (a year in which the redetermination would affect the 
amount of depreciation allowable for the account), salvage value is 
determined to be $52,000 after taking into account the reduction under 
section 167(f). Salvage value for the account will be adjusted to 
$52,000.
    Example (3). The facts are the same as in example (1) except that 
upon audit of B's tax return for 1971 the examining officer determines 
the salvage value to be $58,000 (that is, $66,000 minus the $8,000 
reduction under section 167(f)), and proposes to adjust salvage value 
for the account to $58,000 which will result in disallowing an amount of 
depreciation for the taxable year. B does not agree with the finding of 
the examining officer. After receipt of a ``30-day letter,'' B waives a 
district conference and initiates proceedings before the Appellate 
Division. In consideration of the case by the Appellate Division it is 
concluded that there is not sufficient basis for determining an amount 
of salvage value for the account in excess of $55,000 (that is, $63,000 
minus the $8,000 reduction under section 167(f)). Since the salvage 
value of $47,000 established by B for the account is within the 10 
percent range, it is reasonable. Salvage value for the account will not 
be redetermined.
    Example (4). For 1971, taxpayer C elects to apply this section to 
factory building X which is in an item account of 1965, the year in 
which the building was acquired. The unadjusted basis of factory 
building X is $90,000. C estimated a gross salvage value for the account 
of $10,000. The property did not qualify under section 167(f)(2). Thus, 
C establishes a salvage value of $10,000 for the account for 1971. 
Assume that there is not sufficient basis for determining a salvage 
value for the account greater than $14,000. Since the salvage value of 
$10,000 established by C for the account is within the 10-percent range, 
it is reasonable. Salvage value for the account will not be 
redetermined.

    (d) Accounting for qualified property--(1) In general. Qualified 
property for which the taxpayer elects to apply this section may be 
accounted for in any number of item or multiple asset accounts.
    (2) Retirements of qualified property--(i) In general. The 
provisions of this subparagraph and Sec. 1.167(a)-8 apply to 
retirements of qualified property to which the taxpayer elects to apply 
this section for the taxable year. See subdivision (iii) of this 
subparagraph for special rule for normal retirements.
    (ii) Adjusted basis of assets retired. In the case of a taxpayer who 
depreciates qualified property in a multiple-asset account conforming to 
the asset guideline class at a rate based on the class life in 
accordance with paragraph (a)(5)(ii)(a) of this section, Sec. 1.167(a)-
8(c) (relating to basis of assets retired) shall be applied by assuming 
that the class life is the average expected useful life of the assets in 
the account. See Sec. 1.167(a)-8, generally, for the basis of assets 
retired.
    (iii) Definition of normal retirements. Notwithstanding Sec. 
1.167(a)- 8(b), the determination whether a retirement of qualified 
property is normal or abnormal shall be made in light of all the facts 
and circumstances, primarily with reference to the expected period of 
use of the asset in the taxpayer's business without regard to paragraph 
(a)(5)(ii) of this section. A retirement is not abnormal unless the 
taxpayer can show that the withdrawal of the asset was not due to a 
cause which would customarily be contemplated (in light of the 
taxpayer's practice and experience) in setting a depreciation rate for 
the assets without regard to paragraph (a)(5)(ii) of this section. Thus, 
for example, a retirement is normal if made within the range of years 
which would customarily be taken into account in setting such 
depreciation rate and if the asset has reached a condition at

[[Page 984]]

which, in the normal course of events, the taxpayer customarily retires 
similar assets from use in his business. A retirement may be abnormal if 
the asset is withdrawn at an earlier time or under other circumstances, 
as, for example, when the asset has been damaged by casualty or has lost 
its usefulness suddenly as the result of extraordinary obsolescence.
    (3) Special rules--(i) In general. The provisions of this 
subparagraph shall apply to qualified property in a taxable year for 
which an election to apply this section is made.
    (ii) Repairs. For the purpose of sections 162 and 263 and the 
regulations thereunder, whether an expenditure prolongs the life of an 
asset shall be determined by reference to the expected period of use of 
the asset in the taxpayer's business without regard to paragraph 
(a)(5)(ii) of this section.
    (iii) Sale and lease. For the purpose of comparison with the term of 
a lease of such property, the remaining life of qualified property shall 
be determined by reference to the expected period of use of the asset in 
the taxpayer's business without regard to paragraph (a)(5)(ii) of this 
section.
    (4) Expected period of use. For the purposes of subparagraphs (2) 
and (3) of this paragraph, the determination of the expected period of 
use of an asset shall be made in light of all the facts and 
circumstances. The expected period of use of a particular asset will not 
necessarily coincide with the class life used for depreciation (or with 
the individual asset life for depreciation under the alternative method 
in paragraph (a)(5)(ii) (b) of this section for applying the class 
life). Thus, for example, if the question is whether an asset has been 
leased for a period less than, equal to or greater than its remaining 
life, the determination shall be based on the remaining expected period 
of use of the individual asset without regard to the fact that the asset 
is depreciated at a rate based on the class life in accordance with 
paragraph (a)(5)(ii)(a) of this section.
    (5) Leased property. In the case of a lessor of qualified property, 
unless there is an asset guideline class in effect for such lessors, the 
asset guideline class for such property shall be determined by reference 
to the activity in which such property is primarily used by the lessee. 
See paragraph (b)(3) of this section for general rule for classification 
of qualified property according to primary use. However, in the case of 
an asset guideline class based upon the type of property (such as trucks 
or railroad cars), as distinguished from the activity in which used, the 
property shall be classified without regard to the activity of the 
lessee.
    (e) Election under this section--(1) Consent to change in method of 
accounting. An election to apply this section for a taxable year ending 
after December 31, 1970, is a method of accounting but the consent of 
the Commissioner will be deemed granted to make an annual election.
    (2) Election for taxable years ending after December 31, 1976. For 
taxable years ending after December 31, 1976, the election to apply this 
section for a taxable year shall be made by attaching to the income tax 
return a statement that an election under this section is being made. If 
the taxpayer does not file a timely return (taking into account 
extensions of time for filing) for the taxable year, the election shall 
be made at the time the taxpayer files his first return for the taxable 
year. The election may be made with an amended return only if such 
amended return is filed no later than the time prescribed by law 
(including extensions thereof) for filing the return for the taxable 
year. A taxpayer who makes an election under this subparagraph must 
maintain books and records reflecting the information described in 
paragraph (e)(3) (ii) and (iii) of this section.
    (3) Election for taxable years ending on or before December 31, 
1976. (i) For taxable years ending on or before December 31, 1976, the 
election to apply this section for a taxable year may be made by filing 
Form 5006 with the income tax return for the taxable year. If the 
taxpayer does not file a timely return (taking into account extensions 
of time for filing) for the taxable year, the election shall be filed at 
the time the taxpayer files his first return for the taxable year. The 
election may be made with an amended return only if such amended return 
is filed no later

[[Page 985]]

than the later of (a) the time prescribed by law (including extensions 
thereof) for filing the return for the taxable year, or (b) November 5, 
1973.
    (ii) The election to apply this section for a taxable year ending on 
or before December 31, 1976, will be deemed to be made if the tax return 
(filed within the periods referred to in paragraph (e)(3)(i) of this 
section) contains information sufficient to establish the following:
    (a) Each asset guideline class for which the election is intended to 
apply;
    (b) The class life for each such asset guideline class and whether 
the class life is determined under paragraph (b)(1) or (2) of this 
section;
    (c) For each asset guideline class, as of the end of the taxable 
year of election, (1) the total unadjusted basis of all qualified 
property, (2) the aggregate of the reserves for depreciation of all 
accounts in the asset guideline class, and (3) the aggregate of the 
salvage value established for all accounts in the asset guideline class; 
and
    (d) Whether the taxpayer is an electric or gas utility using a 
composite asset guideline class basis in accordance with paragraph 
(b)(3)(iii) of this section.

If an election is deemed to be made under this subdivision (ii), the 
taxpayer will be deemed to have consented to apply all the provisions of 
this section.
    (iii) A taxpayer to whom the election applies shall maintain books 
and records for each asset guideline class reasonably sufficient to 
identify the unadjusted basis, reserve for depreciation and salvage 
value established for each depreciation account in such asset guidelines 
class.
    (f) Depreciation for taxable years ending before January 1, 1971--
(1) Adoption of Revenue Procedure 62-21--(i) In general. Except as 
provided in subdivision (ii) of this subparagraph, a taxpayer may elect 
to be examined under the provisions of Revenue Procedure 62-21 for a 
taxable year ending before January 1, 1971, only in accordance with the 
rules of this paragraph. The election must specify:
    (a) That the taxpayer makes such election and consents to, and 
agrees to apply, all the provisions of this paragraph;
    (b) Each guideline class and taxable year for which the taxpayer 
elects to be examined under Revenue Procedure 62-21;
    (c) The class life claimed for each such guideline class;
    (d) The class life and the total amount of the depreciation for the 
guideline class claimed on the last income tax return for such taxable 
year filed prior to January 12, 1971 (or in case no income tax return 
was filed prior to January 12, 1971, on the first income tax return 
filed for such taxable year);
    (e) The class life claimed and the total amount of depreciation for 
the guideline class under the election to apply Revenue Procedure 62-21, 
in accordance with this paragraph, for the taxable year; and
    (f) If the class life or total amount of depreciation for the 
guideline class is different in (d) and (e) of this subdivision, a 
reasonable description of the computation of the class life in (e) of 
this subdivision, the amount of difference in tax liability resulting 
therefrom, and the amount of any refund or reduction in any deficiency 
in tax. The election shall be made in an amended tax return or claim for 
refund (or by a supplement to the tax return or claim) for the taxable 
year, and if the class life or total amount of depreciation for the 
guideline class is different in accordance with (f) of this subdivision, 
such difference shall be reflected in the amended tax return or claim 
for refund. Forms may be provided for making the election and submission 
of the information. In the case of an election made after issuance of 
such forms and more than 30 days after publication of notice thereof in 
the Internal Revenue Bulletin, the election may be made and the 
information submitted only in accordance with such forms. An election 
will not otherwise be invalid under this paragraph so long as there is 
substantial compliance, in good faith, with the requirements of this 
paragraph.
    (ii) Special rule. The provisions of this subparagraph shall not 
apply to a guideline class in any taxable year for

[[Page 986]]

which the taxpayer has prior to January 12, 1971, adopted Revenue 
Procedure 62-21 for such class. See subparagraph (2) of this paragraph 
for determination of adoption of Revenue Procedure 62-21 prior to 
January 12, 1971.
    (iii) Justification of class life claimed and limitations on 
refunds. If the taxpayer elects for a taxable year to be examined under 
the provisions of Revenue Procedure 62-21 in accordance with subdivision 
(i) of this subparagraph, any of the provisions of Revenue Procedure 62-
21 may be applied to justify a class life claimed on the income tax 
return filed for such year or to offset an increase in tax liability for 
such year. Unless it meets the reserve ratio test, no class life will be 
accepted on audit which (after all other adjustments in tax liability 
for such year)results in a reduction (or further reduction) in the 
amount of tax liability shown on the income tax return (specified in 
subdivision (i)(d) of this subparagraph) for such taxable year, or 
results in an amount of loss carryback or carryover to any taxable year, 
but if it is justified under Revenue Procedure 62-21 and meets the 
reserve ratio test, a class life will be accepted on audit without 
regard to the foregoing limitations and, for example, may produce a 
refund or credit against tax. For example, if a class life of 9 years is 
otherwise justified under Revenue Procedure 62-21 for 1969, but the 
taxpayer does not meet the reserve ratio test for 1969 using a test life 
of 9 years, a class life of 9 years (or any class life justified under 
Revenue Procedure 62-21) will be accepted on audit under Revenue 
Procedure 62-21 pursuant to an election in accordance with this 
paragraph provided it does not result in the reduction or further 
reduction in tax liability or in an amount of loss carryback or 
carryover as described in the preceding sentence. On the other hand, for 
example, if a class life of 10 years is justified under Revenue 
Procedure 62-21 for 1969 and the taxpayer meets the reserve ratio test 
for 1969 using a test life of 10 years, a class life of 10 years will be 
accepted on audit under Revenue Procedure 62-21 pursuant to an election 
in accordance with this paragraph even though it results in a reduction 
or further reduction in tax liability or in an amount of loss carryback 
or carryover as described above and produces a refund of tax. For 
purposes of this section, the term ``audit'' includes examination of 
claims for refund or credit against tax.
    (iv) Definitions. For purposes of this paragraph, the determination 
whether the reserve ratio test is met shall be made in accordance with 
that portion of paragraph (b)(2) of this section which is by express 
reference therein made applicable to this paragraph. In addition, the 
guideline form of the reserve ratio test, as described in Revenue 
Procedure 65-13, may be applied. For purposes of this paragraph, 
references to Revenue Procedure 62-21 include all modifications, 
amendments, and supplements thereto as of January 11, 1971. The terms 
``class life'' and ``guideline class'' have the same meaning as in 
Revenue Procedure 62-21.
    (2) Determination whether Revenue Procedure 62-21 adopted prior to 
January 12, 1971--(i) In general. For the purposes of this paragraph, a 
taxpayer will be treated as having adopted prior to January 12, 1971, 
Revenue Procedure 62-21 for a guideline class for a taxable year ending 
before January 1, 1971, only if--
    (a) For the guideline class and taxable year, the taxpayer adopted 
Revenue Procedure 62-21 by expressly so indicating on the income tax 
return filed for such taxable year prior to January 12, 1971;
    (b) For the guideline class and taxable year, the taxpayer adopted 
Revenue Procedure 62-21 prior to January 12, 1971, by expressly so 
indicating in a proceeding before the Internal Revenue Service (such as 
upon examination of the income tax return for such taxable year) and 
there is reasonable evidence to that effect; or
    (c) There is other reasonable evidence that prior to January 12, 
1971, the taxpayer adopted Revenue Procedure 62-21 for the guideline 
class and taxable year.

If not treated under (b) or (c) of this subdivision as having done so 
for the last taxable year ending before January 1, 1971, and if the 
taxpayer files his first income tax return for such taxable year after 
January 11, 1971, the taxpayer will be treated as having adopted Revenue 
Procedure 62-21 prior

[[Page 987]]

to January 12, 1971, for a guideline class for such taxable year if he 
expressly so indicated on that return, or is treated under this 
subparagraph as having adopted Revenue Procedure 62-21 prior to January 
12, 1971, for that guideline class for the immediately preceding taxable 
year.
    (ii) Examples. The principles of this subparagraph may be 
illustrated by the following examples:

    Example (1). Taxpayer A, an individual who uses the calendar year as 
his taxable year, has property in Group Three, Class 16(a), of Revenue 
Procedure 62-21. On A's income tax return for 1968, filed prior to 
January 12, 1971, he adopted Revenue Procedure 62-21 for the guideline 
class by so indicating under ``Summary of Depreciation'' in the 
appropriate schedule of Form 1040 for 1968. Under subdivision (i) (a) of 
this subparagraph, A is treated as having adopted Revenue Procedure 62-
21 for the guideline class for 1968 prior to January 12, 1971.
    Example (2). Taxpayer B, an individual who uses the calendar year as 
his taxable year, has property in Group Two, Class 5, of Revenue 
Procedure 62-21. B filed timely income tax returns for 1966 through 1968 
but did not adopt Revenue Procedures 62-21 on any of such returns. In 
1969 upon audit of B's taxable years 1966 through 1968, B exercised his 
option to be examined under the provisions of Revenue Procedure 62-21. 
The Revenue Agent's report shows that B was examined under Revenue 
Procedure 62-21 for taxable years 1966 through 1968. B will be treated 
under subdivision (ii)(b) of this subparagraph as having adopted Revenue 
Procedure 62-21 for such years prior to January 12, 1971.
    Example (3). The facts are the same as in example (2) except that B 
did not upon examination by the Revenue Agent in 1969 exercise his 
option to be examined under Revenue Procedure 62-21. B has six accounts 
in the guideline class, Nos. 1 through 6. The Revenue Agent proposed to 
lengthen the depreciable lives on accounts Nos. 2 and 3 from 8 years to 
12 years. In proceedings before the Appellate Division in 1970, B 
exercised his option to be examined under the provisions of Revenue 
Procedure 62-21. This is shown by correspondence between B and the 
Appellate Conferee as well as by other documents in the case before the 
Appellate Division. The case was settled on that basis before the 
Appellate Division without adjustment of the depreciable lives for B's 
accounts Nos. 2 and 3. B will be treated under subdivision (ii) (b) of 
this subparagraph as having adopted Revenue Procedure 62-21 for taxable 
years 1966 through 1968 prior to January 12, 1971.
    Example (4). Corporation X uses the calendar year as its taxable 
year and has assets in Group Two, Class 5, of Revenue Procedure 62-21. 
Beginning in 1964, corporation X used the guideline life of 10 years as 
the depreciable life for all assets in the guideline class. In 1967, 
corporation X's taxable years 1964 through 1966 were examined and 
corporation X exercised its option to be examined under the provisions 
of Revenue Procedure 62-21. Corporation X did not adopt Revenue 
Procedure 62-21 on any of its income tax returns, for the years 1964 
through 1970. Corporation X has not been examined since 1967, but has 
continued to use the guideline life of 10 years for all property in the 
guideline class including additions since 1966. Corporation X will be 
treated under subdivision (ii) (c) and (d) of this subparagraph as 
having adopted Revenue Procedure 62-21 prior to January 12, 1971, for 
taxable years 1964 through 1970.
    Example (5). Corporation Y uses the calendar year as its taxable 
year and has asset in Group Two, Class 5, of Revenue Procedure 62-21. 
Since 1964, corporation Y has used various depreciable lives, based on 
the facts and circumstances, for different accounts in the guideline 
class. Corporation Y was examined in 1968 for taxable years 1965 through 
1967. Corporation Y was also examined in 1970 for taxable years 1968 and 
1969. Corporation Y did not exercise its option to be examined under the 
provisions of Revenue Procedure 62-21. Corporation Y has not adopted 
Revenue Procedure 62-21 on any income tax return. For taxable years 1964 
through 1970, corporation Y's class life (within the meaning of section 
4, Part II, of Revenue Procedure 62-21) was between 12 and 14 years. In 
August of 1971, corporation Y filed amended income tax returns for 1968 
and 1969, and an income tax return for 1970, using a depreciable life of 
10 years (equal to the guideline life) for all assets in the guideline 
class. Corporation Y will not be treated as having adopted Revenue 
Procedure 62-21 prior to January 12, 1971.
    Example (6). Corporation Z uses the calendar year as its taxable 
year and has assets in group 2, class 5, of Revenue Procedure 62-21. 
Corporation Z adopted Revenue Procedure 62-21 for this guideline class 
by expressly so indicating on its tax return for 1966, which was filed 
before January 12, 1971. Corporation Z computed its allowable 
depreciation for 1966 as if it adopted Revenue Procedure 62-21 for this 
guideline class for its taxable years 1962 through 1965, although it had 
earlier filed its tax returns for those years without regard to Revenue 
Procedure 62-21. The depreciation thus claimed in 1966 was less than 
what would have been allowable if corporation Z first adopted Revenue 
Procedure 62-21 in 1966. This was the result of certain accounts 
becoming fully depreciated through use of Revenue Procedure 62-21 in 
computing depreciation for 1962

through 1965. In addition, in deferred tax accounting procedures 
employed before January 12, 1971, for financial reporting purposes, 
corporation Z calculated its tax deferrals on the basis that it had 
adopted Revenue Procedure 62-21 for the years 1962 through 1965. 
Corporation Z will be treated under subdivision (i) (c) of this 
subparagraph as having adopted Revenue Procedure 62-21 for taxable years 
1962 through 1965 prior to January 12, 1971.
