PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.472-8  Dollar-value method of pricing LIFO inventories.

    (a) Election to use dollar-value method. Any taxpayer may elect to 
determine the cost of his LIFO inventories under the so-called ``dollar-
value'' LIFO method, provided such method is used consistently and 
clearly reflects the income of the taxpayer in accordance with the rules 
of this section. The dollar-value method of valuing LIFO inventories is 
a method of determining cost by using ``base-year'' cost expressed in 
terms of total dollars rather than the quantity and price of specific 
goods as the unit of measurement. Under such method the goods contained 
in the inventory are grouped into a pool or pools as described in 
paragraphs (b) and (c) of this section. The term ``base-year cost'' is 
the aggregate of the cost (determined as of the beginning of the taxable 
year for which the LIFO method is first adopted, i.e., the base date) of 
all items in a pool. The taxable year for which the LIFO method is first 
adopted with respect to any item in the pool is the ``base year'' for 
that pool, except as provided in paragraph (g)(3) of this section. 
Liquidations and increments of items contained in the pool shall be 
reflected only in terms of a net liquidation or increment for the pool 
as a whole. Fluctuations may occur in quantities of various items within 
the pool, new items which properly fall within the pool may be added, 
and old items may disappear from the pool, all without necessarily 
effecting a change in the dollar value of the pool as a whole. An 
increment in the LIFO inventory occurs when the end of the year 
inventory for any pool expressed in terms of base-year cost is in excess 
of the beginning of the year inventory for that pool expressed in terms 
of base-year cost. In determining the inventory value for a pool, the 
increment, if any, is adjusted for changing unit costs or values by 
reference to a percentage, relative to base-year-cost, determined for 
the pool as a whole. See paragraph (e) of this section. See also 
paragraph (f) of this section for rules relating to the change to the 
dollar-value LIFO method from another LIFO method.
    (b) Principles for establishing pools of manufacturers and 
processors--(1) Natural business unit pools. A pool shall consist of all 
items entering into the entire inventory investment for a natural 
business unit of a business enterprise, unless the taxpayer elects to 
use the multiple pooling method provided in subparagraph (3) of this 
paragraph. Thus, if a business enterprise is composed of only one 
natural business unit, one pool shall be used for all of its 
inventories, including raw materials, goods in process, and finished

[[Page 524]]

goods. If, however, a business enterprise is actually composed of more 
than one natural business unit, more than one pool is required. Where 
similar types of goods are inventoried in two or more natural business 
units of the taxpayer, the Commissioner may apportion or allocate such 
goods among the various natural business units, if he determines that 
such apportionment or allocation is necessary in order to clearly 
reflect the income of such taxpayer. Where a manufacturer or processor 
is also engaged in the wholesaling or retailing of goods purchased from 
others, any pooling of the LIFO inventory of such purchased goods for 
the wholesaling or retailing operations shall be determined in 
accordance with the rules of paragraph (c) of this section.
    (2) Definition of natural business unit. (i) Whether an enterprise 
is composed of more than one natural business unit is a matter of fact 
to be determined from all the circumstances. The natural business 
divisions adopted by the taxpayer for internal management purposes, the 
existence of separate and distinct production facilities and processes, 
and the maintenance of separate profit and loss records with respect to 
separate operations are important considerations in determining what is 
a business unit, unless such divisions, facilities, or accounting 
records are set up merely because of differences in geographical 
location. In the case of a manufacturer or processor, a natural business 
unit ordinarily consists of the entire productive activity of the 
enterprise within one product line or within two or more related product 
lines including (to the extent engaged in by the enterprise) the 
obtaining of materials, the processing of materials, and the selling of 
manufactured or processed goods. Thus, in the case of a manufacturer or 
processor, the maintenance and operation of a raw material warehouse 
does not generally constitute, of itself, a natural business unit. If 
the taxpayer maintains and operates a supplier unit the production of 
which is both sold to others and transferred to a different unit of the 
taxpayer to be used as a component part of another product, the supplier 
unit will ordinarily constitute a separate and distinct natural business 
unit. Ordinarily, a processing plant would not in itself be considered a 
natural business unit if the production of the plant, although saleable 
at this stage, is not sold to others, but is transferred to another 
plant of the enterprise, not operated as a separate division, for 
further processing or incorporation into another product. On the other 
hand, if the production of a manufacturing or processing plant is 
transferred to a separate and distinct division of the taxpayer, which 
constitutes a natural business unit, the supplier unit itself will 
ordinarily be considered a natural business unit. However, the mere fact 
that a portion of the production of a manufacturing or processing plant 
may be sold to others at a certain stage of processing with the 
remainder of the production being further processed or incorporated into 
another product will not of itself be determinative that the activities 
devoted to the production of the portion sold constitute a separate 
business unit. Where a manufacturer or processor is also engaged in the 
wholesaling or retailing of goods purchased from others, the wholesaling 
or retailing operations with respect to such purchased goods shall not 
be considered a part of any manufacturing or processing unit.
    (ii) The rules of this subparagraph may be illustrated by the 
following examples:

    Example (1). A corporation manufactures, in one division, automatic 
clothes washers and driers of both commercial and domestic grade as well 
as electric ranges, mangles, and dishwashers. The corporation 
manufactures, in another division, radios and television sets. The 
manufacturing facilities and processes used in manufacturing the radios 
and television sets are distinct from those used in manufacturing the 
automatic clothes washers, etc. Under these circumstances, the 
enterprise would consist of two business units and two pools would be 
appropriate, one consisting of all of the LIFO inventories entering into 
the manufacture of clothes washers and driers, electric ranges, mangles, 
and dishwashers and the other consisting of all of the LIFO inventories 
entering into the production of radio and television sets.
    Example (2). A taxpayer produces plastics in one of its plants. 
Substantial amounts of the production are sold as plastics. The 
remainder of the production is shipped to a

[[Page 525]]

second plant of the taxpayer for the production of plastic toys which 
are sold to customers. The taxpayer operates his plastics plant and toy 
plant as separate divisions. Because of the different product lines and 
the separate divisions the taxpayer has two natural business units.
    Example (3). A taxpayer is engaged in the manufacture of paper. At 
one stage of processing, uncoated paper is produced. Substantial amounts 
of uncoated paper are sold at this stage of processing. The remainder of 
the uncoated paper is transferred to the taxpayer's finishing mill where 
coated paper is produced and sold. This taxpayer has only one natural 
business unit since coated and uncoated paper are within the same 
product line.

    (3) Multiple pools--(i) Principles for establishing multiple pools. 
(a) A taxpayer may elect to establish multiple pools for inventory items 
which are not within a natural business unit as to which the taxpayer 
has adopted the natural business unit method of pooling as provided in 
subparagraph (1) of this paragraph. Each such pool shall ordinarily 
consist of a group of inventory items which are substantially similar. 
In determining whether such similarity exists, consideration shall be 
given to all the facts and circumstances. The formulation of detailed 
rules for selection of pools applicable to all taxpayers is not 
feasible. Important considerations to be taken into account include, for 
example, whether there is substantial similarity in the types of raw 
materials used or in the processing operations applied; whether the raw 
materials used are readily interchangeable; whether there is similarity 
in the use of the products; whether the groupings are consistently 
followed for purposes of internal accounting and management; and whether 
the groupings follow customary business practice in the taxpayer's 
industry. The selection of pools in each case must also take into 
consideration such factors as the nature of the inventory items subject 
to the dollar-value LIFO method and the significance of such items to 
the taxpayer's business operations. Where similar types of goods are 
inventoried in natural business units and multiple pools of the 
taxpayer, the Commissioner may apportion or allocate such goods among 
the natural business units and the multiple pools, if he determines that 
such apportionment or allocation is necessary in order to clearly 
reflect the income of the taxpayer.
    (b) Raw materials which are substantially similar shall be pooled 
together in accordance with the principles of this subparagraph. 
However, inventories of raw or unprocessed materials of an unlike nature 
may not be placed into one pool, even though such materials become part 
of otherwise identical finished products.
    (c) Finished goods and goods-in-process in the inventory shall be 
placed into pools classified by major classes or types of goods. The 
same class or type of finished goods and goods-in-process shall 
ordinarily be included in the same pool. Where the material content of a 
class of finished goods and goods-in-process included in a pool has been 
changed, for example, to conform with current trends in an industry, a 
separate pool of finished goods and goods-in-process will not ordinarily 
be required unless the change in material content results in a 
substantial change in the finished goods.
    (d) The requirement that pools be established by major types of 
materials or major classes of goods is not to be construed so as to 
preclude the establishment of a miscellaneous pool. Since a taxpayer may 
elect the dollar-value LIFO method with respect to all or any designated 
goods in his inventory, there may be a number of such inventory items 
covered in the election. A miscellaneous pool shall consist only of 
items which are relatively insignificant in dollar value by comparison 
with other inventory items in the particular trade or business and which 
are not properly includible as part of another pool.
    (ii) Raw materials content pools. The dollar-value method of pricing 
LIFO inventories may be used in conjunction with the raw materials 
content method authorized in Sec. 1.472-1. Raw materials (including the 
raw material content of finished goods and goods-in-process) which are 
substantially similar shall be pooled together in accordance with the 
principles of subdivision (i) of this subparagraph. However, inventories 
of materials of an unlike nature may not be placed into one pool, even 
though

[[Page 526]]

such materials become part of otherwise identical finished products.
    (4) IPIC method pools. A manufacturer or processor that elects to 
use the inventory price index computation method described in paragraph 
(e)(3) of this section (IPIC method) for a trade or business may elect 
to establish dollar-value pools for those items accounted for using the 
IPIC method based on the 2-digit commodity codes (i.e., major commodity 
groups) in Table 6 (Producer price indexes and percent changes for 
commodity groupings and individual items, not seasonally adjusted) of 
the ``PPI Detailed Report'' published monthly by the United States 
Bureau of Labor Statistics (available from New Orders, Superintendent of 
Documents, PO Box 371954, Pittsburgh, PA 15250-7954). A taxpayer 
electing to establish dollar-value pools under this paragraph (b)(4) may 
combine IPIC pools that comprise less than 5 percent of the total 
current-year cost of all dollar-value pools to form a single 
miscellaneous IPIC pool. A taxpayer electing to establish dollar-value 
pools under this paragraph (b)(4) may combine a miscellaneous IPIC pool 
that comprises less than 5 percent of the total current-year cost of all 
dollar-value pools with the largest IPIC pool. Each of these 5 percent 
rules is a method of accounting. A taxpayer may not change to, or cease 
using, either 5 percent rule without obtaining the Commissioner's prior 
consent. Whether a specific IPIC pool or the miscellaneous IPIC pool 
satisfies the applicable 5 percent rule must be determined in the year 
of adoption or year of change (whichever is applicable) and redetermined 
every third taxable year. Any change in pooling required or permitted as 
a result of a 5 percent rule is a change in method of accounting. A 
taxpayer must secure the consent of the Commissioner pursuant to Sec. 
1.446-1(e) before combining or separating pools and must combine or 
separate its IPIC pools in accordance with paragraph (g)(2) of this 
section.
    (c) Principles for establishing pools for wholesalers, retailers, 
etc. (1) In general. Items of inventory in the hands of wholesalers, 
retailers, jobbers, and distributors shall be placed into pools by major 
lines, types, or classes of goods. In determining such groupings, 
customary business classifications of the particular trade in which the 
taxpayer is engaged is an important consideration. An example of such 
customary business classification is the department in the department 
store. In such case, practices are relatively uniform throughout the 
trade, and departmental grouping is peculiarly adapted to the customs 
and needs of the business. However, in appropriate cases, the principles 
set forth in paragraphs (b) (1) and (2) of this section, relating to 
pooling by natural business units, may be used, with permission of the 
Commissioner, by wholesalers, retailers, jobbers, or distributors. Where 
a wholesaler or retailer is also engaged in the manufacturing or 
processing of goods, the pooling of the LIFO inventory for the 
manufacturing or processing operations shall be determined in accordance 
with the rules of paragraph (b) of this section.
    (2) IPIC method pools. A retailer that elects to use the inventory 
price index computation method described in paragraph (e)(3) of this 
section (IPIC method) for a trade or business may elect to establish 
dollar-value pools for those items accounted for using the IPIC method 
based on either the general expenditure categories (i.e., major groups) 
in Table 3 (Consumer Price Index for all Urban Consumers (CPI-U): U.S. 
city average, detailed expenditure categories) of the ``CPI Detailed 
Report'' or the 2-digit commodity codes (i.e., major commodity groups) 
in Table 6 (Producer price indexes and percent changes for commodity 
groupings and individual items, not seasonally adjusted) of the ``PPI 
Detailed Report.'' A wholesaler, jobber, or distributor that elects to 
use the IPIC method for a trade or business may elect to establish 
dollar-value pools for any group of goods accounted for using the IPIC 
method and included within one of the 2-digit commodity codes (i.e., 
major commodity groups) in Table 6 (Producer price indexes and percent 
changes for commodity groupings and individual items, not seasonally 
adjusted) of the ``PPI Detailed Report.'' The ``CPI Detailed Report'' 
and the ``PPI Detailed Report'' are published monthly by the United

[[Page 527]]

States Bureau of Labor Statistics (BLS) (available from New Orders, 
Superintendent of Documents, P.O. Box 371954, Pittsburgh, PA 15250-
7954). A taxpayer electing to establish dollar-value pools under this 
paragraph (c)(2) may combine IPIC pools that comprise less than 5 
percent of the total current-year cost of all dollar-value pools to form 
a single miscellaneous IPIC pool. A taxpayer electing to establish pools 
under this paragraph (c)(2) may combine a miscellaneous IPIC pool that 
comprises less than 5 percent of the total current-year cost of all 
dollar-value pools with the largest IPIC pool. Each of these 5 percent 
rules is a method of accounting. Thus, a taxpayer may not change to, or 
cease using, either 5 percent rule without obtaining the Commissioner's 
prior consent. Whether a specific IPIC pool or the miscellaneous IPIC 
pool satisfies the applicable 5 percent rule must be determined in the 
year of adoption or year of change (whichever is applicable) and 
redetermined every third taxable year. Any change in pooling required or 
permitted under a 5 percent rule is a change in method of accounting. A 
taxpayer must secure the consent of the Commissioner pursuant to section 
1.446-1(e) before combining or separating pools and must combine or 
separate its IPIC pools in accordance with paragraph (g)(2) of this 
section.
    (d) Determination of appropriateness of pools. Whether the number 
and the composition of the pools used by the taxpayer is appropriate, as 
well as the propriety of all computations incidental to the use of such 
pools, will be determined in connection with the examination of the 
taxpayer's income tax returns. Adequate records must be maintained to 
support the base-year unit cost as well as the current-year unit cost 
for all items priced on the dollar-value LIFO inventory method, 
regardless of the method authorized by paragraph (e) of this section 
which is used in computing the LIFO value of the dollar-value pool. The 
pool or pools selected must be used for the year of adoption and for all 
subsequent taxable years unless a change is required by the Commissioner 
in order to clearly reflect income, or unless permission to change is 
granted by the Commissioner as provided in paragraph (e) of Sec. 1.446-
1. However, see paragraph (h) of this section for authorization to 
change the method of pooling in certain specified cases.
    (e) Methods of computation of the LIFO value of a dollar-value 
pool--(1) Methods authorized. A taxpayer may ordinarily use only the so-
called ``double-extension'' method for computing the base-year and 
current-year cost of a dollar-value inventory pool. Where the use of the 
double-extension method is impractical, because of technological 
changes, the extensive variety of items, or extreme fluctuations in the 
variety of the items, in a dollar-value pool, the taxpayer may use an 
index method for computing all or part of the LIFO value of the pool. An 
index may be computed by double-extending a representative portion of 
the inventory in a pool or by the use of other sound and consistent 
statistical methods. The index used must be appropriate to the inventory 
pool to which it is to be applied. The appropriateness of the method of 
computing the index and the accuracy, reliability, and suitability of 
the use of such index must be demonstrated to the satisfaction of the 
district director in connection with the examination of the taxpayer's 
income tax returns. The use of any so-called ``link-chain'' method will 
be approved for taxable years beginning after December 31, 1960, only in 
those cases where the taxpayer can demonstrate to the satisfaction of 
the district director that the use of either an index method or the 
double-extension method would be impractical or unsuitable in view of 
the nature of the pool. A taxpayer using either an index or link-chain 
method shall attach to his income tax return for the first taxable year 
beginning after December 31, 1960, for which the index or link-chain 
method is used, a statement describing the particular link-chain method 
or the method used in computing the index. The statement shall be in 
sufficient detail to facilitate the determination as to whether the 
method used meets the standards set forth in this subparagraph. In 
addition, a copy of the statement shall be filed with the Commissioner 
of Internal Revenue, Attention: T:R, Washington, D.C. 20224. The 
taxpayer shall submit

[[Page 528]]

such other information as may be requested with respect to such index or 
link-chain method. Adequate records must be maintained by the taxpayer 
to support the appropriateness, accuracy, and reliability of an index or 
link-chain method. A taxpayer may request the Commissioner to approve 
the appropriateness of an index or link-chain method for the first 
taxable year beginning after December 31, 1960, for which it is used. 
Such request must be submitted within 90 days after the beginning of the 
first taxable year beginning after December 31, 1960, in which the 
taxpayer desires to use the index or link-chain method, or on or before 
May 1, 1961, whichever is later. A taxpayer entitled to use the retail 
method of pricing LIFO inventories authorized by paragraph (k) of Sec. 
1.472-1 may use retail price indexes prepared by the United States 
Bureau of Labor Statistics. Any method of computing the LIFO value of a 
dollar-value pool must be used for the year of adoption and all 
subsequent taxable years, unless the taxpayer obtains the consent of the 
Commissioner in accordance with paragraph (e) of Sec. 1.446-1 to use a 
different method.
    (2) Double-extension method. (i) Under the double-extension method 
the quantity of each item in the inventory pool at the close of the 
taxable year is extended at both base-year unit cost and current-year 
unit cost. The respective extensions at the two costs are then each 
totaled. The first total gives the amount of the current inventory in 
terms of base-year cost and the second total gives the amount of such 
inventory in terms of current-year cost.
    (ii) The total current-year cost of items making up a pool may be 
determined--
    (a) By reference to the actual cost of the goods most recently 
purchased or produced;
    (b) By reference to the actual cost of the goods purchased or 
produced during the taxable year in the order of acquisition;
    (c) By application of an average unit cost equal to the aggregate 
cost of all of the goods purchased or produced throughout the taxable 
year divided by the total number of units so purchased or produced; or
    (d) Pursuant to any other proper method which, in the opinion of the 
Commissioner, clearly reflects income.
    (iii) Under the double-extension method a base-year unit cost must 
be ascertained for each item entering a pool for the first time 
subsequent to the beginning of the base year. In such a case, the base-
year unit cost of the entering item shall be the current-year cost of 
that item unless the taxpayer is able to reconstruct or otherwise 
establish a different cost. If the entering item is a product or raw 
material not in existence on the base date, its cost may be 
reconstructed, that is, the taxpayer using reasonable means may 
determine what the cost of the item would have been had it been in 
existence in the base year. If the item was in existence on the base 
date but not stocked by the taxpayer, he may establish, by using 
available data or records, what the cost of the item would have been to 
the taxpayer had he stocked the item. If the base-year unit cost of the 
entering item is either reconstructed or otherwise established to the 
satisfaction of the Commissioner, such cost may be used as the base-year 
unit cost in applying the double-extension method. If the taxpayer does 
not reconstruct or establish to the satisfaction of the Commissioner a 
base-year unit cost, but does reconstruct or establish to the 
satisfaction of the Commissioner the cost of the item at some year 
subsequent to the base year, he may use the earliest cost which he does 
reconstruct or establish as the base-year unit cost.
    (iv) To determine whether there is an increment or liquidation in a 
pool for a particular taxable year, the end of the year inventory of the 
pool expressed in terms of base-year cost is compared with the beginning 
of the year inventory of the pool expressed in terms of base-year cost. 
When the end of the year inventory of the pool is in excess of the 
beginning of the year inventory of the pool an increment occurs in the 
pool for that year. If there is an increment for the taxable year, the 
ratio of the total current-year cost of the pool to the total base-year 
cost of the pool must be computed. This ratio when multiplied by the 
amount of the increment measured in terms of base-year

[[Page 529]]

cost gives the LIFO value of such increment. The LIFO value of each such 
increment is hereinafter referred to in this section as the ``layer of 
increment'' and must be separately accounted for and a record thereof 
maintained as a separate layer of the pool, and may not be combined with 
a layer of increment occurring in a different year. On the other hand, 
when the end of the year inventory of the pool is less than the 
beginning of the year inventory of the pool, a liquidation occurs in the 
pool for that year. Such liquidation is to be reflected by reducing the 
most recent layer of increment by the excess of the beginning of the 
year inventory over the end of the year inventory of the pool. However, 
if the amount of the liquidation exceeds the amount of the most recent 
layer of increment, the preceding layers of increment in reverse 
chronological order are to be successively reduced by the amount of such 
excess until all the excess is absorbed. The base-year inventory is to 
be reduced by liquidation only to the extent that the aggregate of all 
liquidation exceeds the aggregate of all layers of increment.
    (v) The following examples illustrate inventories under the double-
extension the computation of the LIFO value of method.

    Example (1). (a) A taxpayer elects, beginning with the calendar year 
1961, to compute his inventories by use of the LIFO inventory method 
under section 472 and further elects to use the dollar-value method in 
pricing such inventories as provided in paragraph (a) of this section. 
He creates Pool No. 1 for items A, B, and C. The composition of the 
inventory for Pool No. 1 at the base date, January 1, 1961, is as 
follows:

------------------------------------------------------------------------
                                                          Unit    Total

  Total base-year cost at Jan. 1, 1961.........  ......  ......   14,000
------------------------------------------------------------------------

    (b) The closing inventory of Pool No. 1 at December 31, 1961, 
contains 3,000 units of A, 1,000 units of B, and 500 units of C. The 
taxpayer computes the current-year cost of the items making up the pool 
by reference to the actual cost of goods most recently purchased. The 
most recent purchases of items A, B, and C are as follows:

------------------------------------------------------------------------
                                                       Quantity    Unit

A...............................  Dec. 15, 1961.....      3,500    $6.00
B...............................  Dec. 10, 1961.....      2,000     5.00
C...............................  Nov. 1, 1961......        500     2.50
------------------------------------------------------------------------

    (c) The inventory of Pool No. 1 at December 31, 1961, shown at base-
year and current-year cost is as follows:

    (d) If the amount of the December 31, 1961, inventory at base-year 
cost were equal to, or less than, the base-year cost of $14,000 at 
January 1, 1961, such amount would be the closing LIFO inventory at 
December 31, 1961. However, since the base-year cost of the closing LIFO 
inventory at December 31, 1961, amounts to $20,000, and is in excess of 
the $14,000 base-year cost of the opening inventory for that year, there 
is a $6,000 increment in Pool No. 1 during the year. This increment must 
be valued at current-year cost, i.e., the ratio of 24,250/20,000, or 
121.25 percent. The LIFO value of the inventory at December 31, 1961, is 
$21,275, computed as follows:

    Example (2). (a) Assume the taxpayer in example (1) during the year 
1962 completely disposes of item C and purchases item D. Assume further 
that item D is properly includible in Pool No. 1 under the provisions of 
this section. The closing inventory on December 31, 1962, consists of 
quantities at current-year unit cost, as follows:

    (b) The taxpayer establishes that the cost of item D, had he 
acquired it on January 1, 1961, would have been $2.00 per unit. Such 
cost shall be used as the base-year unit cost for item D, and the LIFO 
computations at December 31, 1962, are made as follows:

    (c) Since the closing inventory at base-year cost, $18,000, is less 
than the 1962 opening inventory at base-year cost, $20,000, a 
liquidation of $2,000 has occurred during 1962. This liquidation is to 
be reflected by reducing the most recent layer of increment. The LIFO 
value of the inventory at December 31, 1962, is $18,850, and is 
summarized as follows:

    (3) Inventory price index computation (IPIC) method--(i) In general. 
The inventory price index computation method provided by this paragraph 
(e)(3) (IPIC method) is an elective method of determining the LIFO value 
of a dollar-value pool using consumer or producer price indexes 
published by the United States Bureau of Labor Statistics (BLS). A 
taxpayer using the IPIC method must compute a separate inventory price 
index (IPI) for each dollar-value pool. This IPI is used to convert the 
total current-year cost of the items in a dollar-value pool to base-year 
cost in order to determine whether there is an increment or liquidation 
in terms of base-year cost and, if there is an increment, to determine 
the LIFO inventory value of the current year's layer of increment 
(layer). Using one IPI to compute the base-year cost of a dollar-value 
pool for the current taxable year and using a different IPI to compute 
the LIFO inventory value of the current taxable year's layer is not 
permitted under the IPIC method. The IPIC method will be accepted by the 
Commissioner as an appropriate method of computing an index, and the use 
of that index to compute the LIFO value of a dollar-value pool will be 
accepted as accurate, reliable, and suitable. The appropriateness of a 
taxpayer's computation of an IPI, which includes all the steps described 
in paragraph (e)(3)(iii) of this section, will be determined in 
connection with an examination of the taxpayer's federal income tax 
return. A taxpayer using the IPIC method may elect to establish dollar-
value pools according to the special rules in paragraphs (b)(4) and 
(c)(2) of this section or the general rules in paragraphs (b) and (c) of 
this section. Taxpayers eligible to use the IPIC method are described in 
paragraph (e)(3)(ii) of this section. The manner in which an IPI is 
computed is described in paragraph (e)(3)(iii) of this section. Rules 
relating to the adoption of, or change to, the IPIC method are in 
paragraph (e)(3)(iv) of this section.
    (ii) Eligibility. Any taxpayer electing to use the dollar-value LIFO 
method may elect to use the IPIC method. Except as provided in this 
paragraph (e)(3)(ii) or in other published guidance, a taxpayer that 
elects to use the IPIC method for a specific trade or business must use 
that method to account for all items of dollar-value LIFO inventory. A 
taxpayer that uses the retail price indexes computed by the BLS and 
published in ``Department Store Inventory Price Indexes'' (available 
from the BLS by calling (202) 606-6325 and entering document code 2415) 
may elect to use the IPIC method for items that do not fall within any 
of the major groups listed in ``Department Store Inventory Price 
Indexes.''
    (iii) Computation of an inventory price index--(A) In general. The 
computation

[[Page 531]]

of an IPI for a dollar-value pool requires the following four steps, 
which are described in more detail in this paragraph (e)(3)(iii): First, 
selection of a BLS table and an appropriate month; second, assignment of 
items in a dollar-value pool to BLS categories (selected BLS 
categories); third, computation of category inflation indexes for 
selected BLS categories; and fourth, computation of the IPI. A taxpayer 
may compute the IPI for each dollar-value pool using either the double-
extension method (double-extension IPIC method) or the link-chain method 
(link-chain IPIC method), without regard to whether the use of a double-
extension method is impractical or unsuitable. The use of either the 
double-extension IPIC method or the link-chain IPIC method is a method 
of accounting, and the adopted method must be applied consistently to 
all dollar-value pools within a trade or business accounted for under 
the IPIC method. A taxpayer that wants to change from the double-
extension IPIC method to the link-chain IPIC method, or vice versa, must 
secure the consent of the Commissioner under Sec. 1.446-1(e). This 
change must be made with a new base year as described in paragraph 
(e)(3)(iv)(B)(1).
    (B) Selection of BLS table and appropriate month--(1) In general. 
Under the IPIC method, an IPI is computed using the consumer or producer 
price indexes for certain categories (BLS price indexes and BLS 
categories, respectively) listed in the selected BLS table of the ``CPI 
Detailed Report'' or the ``PPI Detailed Report'' for the appropriate 
month.
    (2) BLS table selection. Manufacturers, processors, wholesalers, 
jobbers, and distributors must select BLS price indexes from Table 6 
(Producer price indexes and percent changes for commodity groupings and 
individual items, not seasonally adjusted) of the ``PPI Detailed 
Report'', unless the taxpayer can demonstrate that selecting BLS price 
indexes from another table of the ``PPI Detailed Report'' is more 
appropriate. Retailers may select BLS price indexes from either Table 3 
(Consumer Price Index for all Urban Consumers (CPI-U): U.S. city 
average, detailed expenditure categories) of the ``CPI Detailed Report'' 
or from Table 6 (or another more appropriate table) of the ``PPI 
Detailed Report.'' The selection of a BLS table is a method of 
accounting and must be used for the taxable year of adoption and all 
subsequent years, unless the taxpayer obtains the Commissioner's consent 
under Sec. 1.446-1(e) to change its table selection. A taxpayer that 
changes its BLS table must establish a new base year in the year of 
change as described in paragraph (e)(3)(iv)(B) of this section.
    (3) Appropriate month. In the case of a retailer using the retail 
method, the appropriate month is the last month of the retailer's 
taxable year. In the case of all other taxpayers, the appropriate month 
is the month most consistent with the method used to determine the 
current-year cost of the dollar-value pool under paragraph (e)(2)(ii) of 
this section and the taxpayer's history of inventory production or 
purchases during the taxable year. A taxpayer not using the retail 
method may annually select an appropriate month for each dollar-value 
pool or make an election on Form 970, ``Application to Use LIFO 
Inventory Method,'' to use a representative appropriate month 
(representative month). An election to use a representative month is a 
method of accounting and the month elected must be used for the taxable 
year of the election and all subsequent taxable years, unless the 
taxpayer obtains the Commissioner's consent under Sec. 1.446-1(e) to 
change or revoke its election.
    (4) Examples. The following examples illustrate the rules of this 
paragraph (e)(3)(iii)(B)(3):

    Example 1. Determining an appropriate month. A wholesaler of 
seasonal goods timely files a Form 970, ``Application to Use LIFO 
Inventory Method,'' for the taxable year ending December 31, 2001. The 
taxpayer indicates elections to use the dollar-value LIFO method, to 
determine the current-year cost using the earliest acquisitions method 
in accordance with paragraph (e)(2)(ii)(b) of this section, and to use 
the IPIC method under paragraph (e)(3) of this section. Although the 
taxpayer purchases inventory items regularly throughout the year, the 
items purchased vary according to the seasons. The seasonal items on 
hand at December 31, 2001, are purchased between October and December. 
Thus, based on the taxpayer's use of the earliest acquisitions method of 
determining

[[Page 532]]

current-year cost and its experience with inventory purchases, the 
appropriate month for the items represented in the ending inventory at 
December 31, 2001, is October.
    Example 2. Electing a representative month. A retailer not using the 
retail method timely files a Form 970, ``Application to Use LIFO 
Inventory Method,'' for the taxable year ending December 31, 2001. The 
taxpayer indicates elections to use the dollar-value LIFO method, the 
most recent purchases method of determining current-year cost under 
paragraph (e)(2)(ii)(a) of this section, the IPIC method under paragraph 
(e)(3) of this section, and December as its representative month under 
paragraph (e)(3)(iii)(B)(3) of this section. The items in the taxpayer's 
ending inventory are purchased fairly uniformly throughout the year, 
with the first purchases normally occurring in January and the last 
purchases normally occurring in December. The taxpayer's election to use 
December as its representative month is permissible because the taxpayer 
elected to use the most recent purchases method and the taxpayer's last 
purchases of the taxable year normally occur during December, the last 
month of the taxpayer's taxable year.
    Example 3. Changing representative month. The facts are the same as 
in Example 2, except the taxpayer files a Form 3115, ``Application for 
Change in Accounting Method,'' requesting permission to change to the 
earliest acquisitions method of determining current-year cost in 
accordance with paragraph (e)(2)(ii)(b) of this section and to change 
its representative month from December to January beginning with the 
taxable year ending December 31, 2003. If the Commissioner consents to 
the taxpayer's request to change to the earliest acquisitions method, 
December will no longer be a permissible representative month for this 
taxpayer because of the absence of a nexus between the earliest 
acquisitions method, the month of December (the last month of the 
taxpayer's taxable year), and the taxpayer's experience with inventory 
purchases during the year. Thus, the Commissioner will permit the 
taxpayer to change its representative month to January, the first month 
of the taxpayer's taxable year.
    Example 4. Changing representative month. The facts are the same as 
in Example 2. In 2002, the taxpayer changes its annual accounting period 
to a taxable year ending June 30, which requires the taxpayer to file a 
return for the short taxable year beginning January 1, 2002, and ending 
June 30, 2002. As a result, December is no longer a permissible 
representative month because of the absence of a nexus between the most 
recent purchases method, the month of December, and the taxpayer's 
experience with inventory purchases during the year. The taxpayer should 
file a Form 3115 requesting permission to change its representative 
month from December to June beginning with the short taxable year ending 
June 30, 2002. Because the taxpayer's last purchases of the taxable year 
now will occur in June, the Commissioner will consent to the taxpayer's 
request to change its representative month to June.
    Example 5. Changing representative month. The facts are the same as 
in Example 2, except that the taxpayer elects to use January as its 
representative month. The taxpayer timely files a Form 3115 requesting 
permission to change its representative month from January to December 
beginning with the taxable year ending December 31, 2003. January is not 
a permissible representative month because of the absence of a nexus 
between the most recent purchases method, the taxpayer's history of 
inventory purchases, and the month of January, the first month in the 
taxpayer's taxable year. Because December is a permissible 
representative month, the Commissioner will permit the taxpayer to 
change its representative month to December.

    (C) Assignment of inventory items to BLS categories--(1) In general. 
Except as provided in paragraph (e)(3)(iii)(C)(2) of this section, a 
taxpayer must assign each item in a dollar-value pool to the most-
detailed BLS category of the selected BLS table that contains that item. 
For example, in Table 6 of the ``PPI Detailed Report'' for a given 
month, the commodity codes for the various BLS categories run from 2 to 
8 digits, with the least-detailed BLS categories having a 2-digit code 
and the most-detailed BLS categories usually (but not always) having an 
8-digit code. For purposes of assigning items to the most-detailed BLS 
category, manufacturers and processors must assign each raw material 
item to the most-detailed PPI category that includes that raw material 
and must assign each finished good item to the most-detailed PPI 
category that includes that finished good. In addition, manufacturers 
and processors must assign each work-in-process (WIP) item to the most-
detailed PPI category that includes the finished good into which the 
item will be manufactured or processed. For this purpose, finished good 
means a salable item that the taxpayer regularly sells. For example, a 
gasoline-engine manufacturer that also manufactures the pistons used in 
those engines and regularly sells some of the pistons (e.g., to 
retailers of replacement parts) must assign both finished pistons that 
have

[[Page 533]]

not been affixed to an engine block and piston WIP items to the most-
detailed PPI category that includes pistons. Finished pistons that have 
been affixed to an engine block must be assigned to the most-detailed 
PPI category that includes gasoline engines. In contrast, if sales of 
these pistons occur infrequently, the taxpayer must assign both finished 
pistons and piston WIP items to the most-detailed PPI category that 
includes gasoline engines.
    (2) 10 percent method. Instead of assigning each item in a dollar-
value pool to the most-detailed BLS categories, as described in 
paragraph (e)(3)(iii)(C)(1) of this section, a taxpayer may elect to use 
the 10 percent method described in this paragraph (e)(3)(iii)(C)(2). 
Under the 10 percent method, items are assigned to BLS categories using 
a three-step procedure. First, when the current-year cost of a specific 
item is 10 percent or more of the total current-year cost of the dollar-
value pool, the taxpayer must assign that item to the most-detailed BLS 
category that includes that item (10 percent BLS category). Any other 
item that is includible in that 10 percent BLS category (other than an 
item that qualifies for its own 10 percent BLS category under the 
preceding sentence) must be assigned to that 10 percent BLS category. 
Second, if one or more items have not been assigned to BLS categories in 
the first step, the taxpayer must investigate successively less-detailed 
BLS categories and assign the unassigned item(s) to the first BLS 
category that contains unassigned items whose current-year cost, in the 
aggregate, is 10 percent or more of the total current-year cost of the 
dollar-value pool (also, 10 percent BLS categories). This step must be 
repeated until all the items in the dollar-value pool have been included 
in an appropriate 10 percent BLS category, the current-year cost of the 
unassigned items, in the aggregate, is less than 10 percent of the total 
current-year cost of the dollar-value pool, or the taxpayer determines 
that a single BLS category is not appropriate for the aggregate of the 
unassigned items. Third, if items in a dollar-value pool have not been 
assigned to a 10 percent BLS category because the current-year cost of 
those items, in the aggregate, is less than 10 percent of the total 
current-year cost of the dollar-value pool, the taxpayer must assign 
those items to the most-detailed BLS category that includes all those 
items (also, a 10 percent category). On the other hand, if items in a 
dollar-value pool have not been assigned to a 10 percent BLS category 
because the taxpayer determines that a single BLS category is not 
appropriate for the aggregate of those items, the taxpayer must assign 
each of those items to a single miscellaneous BLS category created by 
the taxpayer (also, a 10 percent category). In no event may a taxpayer 
assign items in a dollar-value pool to a BLS category that is less 
detailed than either the major groups of consumer goods described in 
Table 3 of the monthly ``CPI Detailed Report'' or the major commodity 
groups of producer goods described in Table 6 of the monthly ``PPI 
Detailed Report.'' Principles similar to those described in paragraph 
(e)(3)(iii)(C)(1) apply for purposes of assigning raw material, work-in-
process, and finished good items to the most-detailed BLS category under 
the 10 percent method.
    (3) Change in method of accounting. The 10 percent method of 
assigning items in a dollar-value pool to BLS categories is a method of 
accounting. In addition, a taxpayer's selection of a BLS category for a 
specific item is a method of accounting. However, the assignment of 
items to different BLS categories solely as a result of the application 
of the 10 percent method is a change in underlying facts and not a 
change in method of accounting. Likewise, the selection of a new BLS 
category for a specific item as a result of a revision to a BLS table is 
a change in underlying facts and not a change in method of accounting. A 
taxpayer that wants to change its method of selecting BLS categories 
(i.e., to or from the 10-percent method) or of selecting a BLS category 
for a specific item must secure the Commissioner's consent in accordance 
with Sec. 1.446-1(e). A taxpayer that voluntarily changes its method of 
selecting BLS categories or of selecting a BLS category for a specific 
item must establish a new base year in the

year of change as described in paragraph (e)(3)(iv)(B) of this section.
    (D) Computation of a category inflation index--(1) In general. As 
described in more detail in this paragraph (e)(3)(iii)(D), a category 
inflation index reflects the inflation that occurs in the BLS price 
indexes for a selected BLS category (or, if applicable, 10 percent BLS 
category) during the relevant measurement period.
    (2) BLS price indexes. The BLS price indexes are the cumulative 
indexes published in the selected BLS table for the appropriate month. A 
taxpayer may elect to use either preliminary or final BLS price indexes 
for the appropriate month, provided that the selected BLS price indexes 
are used consistently. However, a taxpayer that elects to use final BLS 
price indexes for the appropriate month must use preliminary BLS price 
indexes for any taxable year for which the taxpayer files its original 
federal income tax return before the BLS publishes final BLS price 
indexes for the appropriate month. If a BLS price index for a most-
detailed or 10 percent BLS category is not otherwise available for the 
appropriate or representative month (but not because the BLS categories 
in the BLS table have been revised), the taxpayer must use the BLS price 
index for the next most-detailed BLS category that includes the specific 
item(s) in the most-detailed or 10 percent BLS category. If a BLS price 
index is not otherwise available for the appropriate or representative 
month because the BLS categories in the BLS table have been revised, the 
rules of paragraph (e)(3)(iii)(D)(4) of this section apply.
    (3) Category inflation index. (i) In general. Except as provided in 
paragraph (e)(3)(iii)(D)(4) of this section (concerning compound 
category inflation indexes) or (e)(3)(iii)(D)(5) of this section 
(concerning category inflation indexes for certain 10 percent BLS 
categories), a category inflation index for a selected BLS category (or, 
if applicable, 10 percent BLS category) is computed under the rules of 
this paragraph (e)(3)(iii)(D)(3).
    (ii) Double-extension IPIC method. In the case of a taxpayer using 
the double-extension IPIC method, the category inflation index for a BLS 
category is the quotient of the BLS price index for the appropriate or 
representative month of the current year divided by the BLS price index 
for the appropriate month of the taxable year preceding the base year 
(base month). However, if the taxpayer did not have an opening inventory 
in the year that its election to use the dollar-value LIFO method and 
double-extension IPIC method became effective, the category inflation 
index for a BLS category is the quotient of the BLS price index for the 
appropriate or representative month of the current year divided by the 
BLS price index for the month immediately preceding the month of the 
taxpayer's first inventory production or purchase.
    (iii) Link-chain IPIC method. In the case of a taxpayer using the 
link-chain IPIC method, the category inflation index for a BLS category 
is the quotient of the BLS price index for the appropriate or 
representative month of the current year divided by the BLS price index 
for the appropriate month used for the immediately preceding taxable 
year. However, if the taxpayer did not have an opening inventory in the 
year that its election to use the dollar-value LIFO method and link-
chain IPIC method became effective, the category inflation index for a 
BLS category for the year of election is the quotient of the BLS price 
index for the appropriate or representative month of the current year 
divided by the BLS price index for the month immediately preceding the 
month of the taxpayer's first inventory production or purchase.
    (iv) Special rules concerning representative months. A taxpayer 
electing to use a representative month under paragraph (e)(3)(iii)(B)(3) 
of this section must use an appropriate month, rather than the 
representative month, to determine category inflation indexes in the 
circumstances described in this paragraph (e)(3)(iii)(D)(3)(iv) and in 
other similar circumstances. For example, in the case of a short taxable 
year, the category inflation index should reflect the inflation that 
occurs from the base month (in the case of the double-extension IPIC 
method), or the appropriate or representative month used for the 
preceding taxable year (in

[[Page 535]]

the case of the link-chain IPIC method), and the appropriate month for 
the short taxable year. Similarly, if a taxpayer using the link-chain 
IPIC method is granted consent to change both its method of determining 
the current-year cost of a dollar-value pool and its representative 
month, the category inflation index for the year of change should 
reflect the inflation that occurs between the old representative month 
used for the preceding taxable year and the new representative month 
used for the year of change.
    (4) Compound category inflation index for revised BLS categories or 
price indexes--(i) In general. Periodically, the BLS revises a BLS table 
to add one or more new BLS categories, eliminate one or more previously 
reported BLS categories, or reset the base-year BLS price index of one 
or more BLS categories. If the BLS has revised the applicable BLS table 
for a taxable year, a taxpayer must compute the category inflation index 
for each BLS category for which the taxpayer cannot compute a category 
inflation index in accordance with paragraph (e)(3)(iii)(D)(3) of this 
section (affected BLS category) using a reasonable method, provided the 
method is used consistently for all affected BLS categories within a 
particular taxable year. For example, if the BLS revised the CPI by 
adding new BLS categories as of January 2001 and eliminating some 
previously reported BLS categories as of December 2000, January 2002 
would be the first month for which it would be possible to compute a 
category inflation index for a 12-month period using the BLS price 
indexes for any affected category. The compound category inflation index 
described in paragraph (e)(3)(iii)(D)(4)(ii) of this section is a 
reasonable method of computing the category inflation index for an 
affected BLS category.
    (ii) Computation of compound category inflation index. When the 
applicable BLS table is revised as described in paragraph 
(e)(3)(iii)(D)(4)(i) of this section, a taxpayer may use the procedure 
described in this paragraph (e)(3)(iii)(D)(4)(ii) to compute a compound 
category inflation index for each affected BLS category represented in 
the taxpayer's ending inventory. For this purpose, a compound category 
inflation index is the product of the category inflation index for the 
``first portion'' multiplied by the corresponding category inflation 
index for the ``second portion.'' The category inflation index for the 
first portion must reflect the inflation that occurs between the end of 
the base month (in the case of the double-extension IPIC method), or the 
preceding year's appropriate or representative month (in the case of the 
link-chain IPIC method), and the end of the last month covered by the 
unrevised BLS table based on the old BLS category. The corresponding 
category inflation index for the second portion must reflect the 
inflation that occurs between the beginning of the first month covered 
by the revised BLS table based on the new BLS category and the end of 
the current year's appropriate or representative month. First, using the 
revised BLS table for the current-year's appropriate or representative 
month, the taxpayer assigns items in the dollar-value pool using its 
method of assigning items to BLS categories as described in paragraph 
(e)(3)(iii)(C) of this section. Second, for each affected BLS category 
represented in the ending inventory, the taxpayer computes the category 
inflation index for the second portion using this formula: [A/B], where 
A equals the BLS price index for the current year's appropriate or 
representative month and B equals the BLS price index for the last month 
covered by the unrevised BLS table (as published for the first month of 
the revised BLS table). Third, using the unrevised BLS table for the 
base month (in the case of the double extension IPIC method) or the 
preceding year's appropriate or representative month (in the case of the 
link-chain IPIC method), the taxpayer assigns each of the items in the 
dollar-value pool using its method of assigning items to BLS categories. 
Fourth, for each affected BLS category represented in the ending 
inventory, the taxpayer computes the category inflation index for the 
first portion using this formula: [C/D], where C equals the BLS price 
index for the last month covered by the unrevised BLS table (as 
published for the last month of the unrevised BLS table) and D equals 
the BLS price index for the base month (in

[[Page 536]]

the case of the double-extension IPIC method) or the preceding year's 
appropriate or representative month (in the case of the link-chain IPIC 
method). Fifth, for each affected BLS category represented in the ending 
inventory, the taxpayer computes the compound category inflation index 
using this formula: [X*Y], where X equals the category inflation index 
for the second portion, and Y equals the corresponding category 
inflation index for the first portion. For the purpose of computing the 
compound category inflation index for each affected BLS category, the 
corresponding category inflation index for the first portion is the 
category inflation index for the unrevised BLS category that includes 
the specific inventory item(s) included in the revised BLS category. If 
items included in a single revised BLS category had been included in 
separate BLS categories before the revision of the BLS table, the 
corresponding category inflation index for the first portion is the 
weighted harmonic mean of the category inflation indexes for these 
unrevised BLS categories. See paragraph (e)(3)(iii)(E)(1) of this 
section for a formula of the weighted harmonic mean. When computing this 
weighted-average category inflation index, a taxpayer must use the 
current-year costs (or in the case of a retailer using the retail 
method, the retail selling prices) in ending inventory as the weights.
    (iii) New base year. A taxpayer may establish a new base year in the 
year following the taxable year for which the taxpayer computed a 
compound category inflation index under this paragraph (e)(3)(iii)(D)(4) 
for one or more affected BLS categories in a dollar-value pool. See 
paragraph (e)(3)(iv)(B) of this section for the procedures and 
computations incident to establishing a new base year.
    (iv) Examples. The following examples illustrate the rules of this 
paragraph (e)(3)(iii)(D)(4):

    Example 1. BLS categories eliminated. (i) A retailer, whose taxable 
year ends January 31, elected to account for its inventories using the 
dollar-value LIFO method and double-extension IPIC method (based on the 
CPI), beginning with the taxable year ending January 31, 1997. The 
taxpayer does not use the retail method, but elected to use January as 
its representative month. On January 31, 1999, the taxpayer's only 
dollar-value pool contains only two items--lemons and peaches. The total 
current-year cost of these items is as follows: lemons, $40, and 
peaches, $30. (ii) The CPI was revised in October of 1998 to eliminate 
the ``Citrus fruits'' subcategory of ``Other fresh fruits.'' In 
addition, the base-year BLS price index for ``Other fresh fruits'' was 
reset to 100.00 as of October 1, 1998. In relevant part, the January 
1999 CPI permits the assignment of both lemons and peaches to ``Other 
fresh fruits.'' The January 1999 BLS price indexes for ``Citrus fruits'' 
and ``Other fresh fruits'' are 96.6 and 105.6, respectively. In relevant 
part, the September 1998 CPI permits the assignment of lemons to 
``Citrus fruits'' and peaches to ``Other fresh fruits.'' The September 
1998 BLS price indexes for ``Citrus fruits'' and ``Other fresh fruits'' 
are 194.9 and 294.9, respectively, and the January 1997 BLS price 
indexes for ``Citrus fruits'' and ``Other fresh fruits'' are 190.2 and 
290.2, respectively.
    (iii) Because the BLS eliminated the category, ``Citrus fruits,'' as 
of October 1998, it did not publish a BLS price index for that category 
in the January 1999 CPI. Thus, the taxpayer cannot compute a category 
inflation index for ``Citrus fruits'' under the normal procedures, but 
may compute a compound category inflation index for that affected BLS 
category using the procedures described in paragraph 
(e)(3)(iii)(D)(4)(ii) of this section.
    (iv) The taxpayer computes a compound category inflation index for 
the two BLS categories that formerly included lemons and peaches. The 
taxpayer first assigns lemons and peaches to ``Other fresh fruits,'' the 
most-detailed index in the January 1999 CPI, and then computes the 
category inflation index for the second portion as follows:

----------------------------------------------------------------------------------------------------------------
                                                                       Jan. 1999 index/Sept.
              Item                          1999 category                  1998 index (as           Category
                                                                      published in Oct. 1998)   inflation index
----------------------------------------------------------------------------------------------------------------
Lemons and Peaches.............  Other fresh fruits.................              105.6/100.0             1.0560
----------------------------------------------------------------------------------------------------------------

    (v) The taxpayer assigns the lemons and peaches to the most-detailed 
BLS categories in the January 1998 CPI as follows: lemons to ``Citrus 
fruits'' and peaches to ``Other fresh fruits.'' Then, the taxpayer 
computes the category inflation index for the first portion as follows:

[[Page 537]]



----------------------------------------------------------------------------------------------------------------
                                                                       Sept. 1998 index (as
             Item                          1998 category                published in Sept.    Category inflation
                                                                         1998)/Jan. 1997             index
----------------------------------------------------------------------------------------------------------------
Lemons........................  Citrus fruits......................              194.9/190.2             1.0247
Peaches.......................  Other fresh Fruits.................              294.9/290.2             1.0162
----------------------------------------------------------------------------------------------------------------

    (vi) Because lemons and peaches, which are included together in the 
revised ``Other fresh fruits'' category, had been included in separate 
BLS categories before the BLS table was revised, the taxpayer must 
compute a single corresponding category inflation index for the affected 
BLS categories for the first portion. This corresponding category 
inflation index is the weighted harmonic mean of the separate 
corresponding category inflation indexes for the first portion using the 
cost of the items in ending inventory as the weights. The taxpayer 
computes the corresponding category inflation index for ``Other fresh 
fruits'' for the first portion as follows:

----------------------------------------------------------------------------------------------------------------
                                                               (I)  Weight     (II)  Category   (III)  Quotient:
                           Item                              (cost of item)    inflation index      (I)/(II)
----------------------------------------------------------------------------------------------------------------
Lemons....................................................            $40.00            1.0247            $39.04
Peaches...................................................             30.00            1.0162             29.52
                                                           -------------------
    Total.................................................             70.00  ................             68.56
----------------------------------------------------------------------------------------------------------------


----------------------------------------------------------------------------------------------------------------
                                                                (V)  Sum of (weight/     (VI)  Weighted harmonic
                    (IV)  Sum of weights                         category inflation        mean of other fresh
                                                                       index)               fruits: (IV)/(V)
----------------------------------------------------------------------------------------------------------------
$70.00......................................................                   $68.56                    1.0210
----------------------------------------------------------------------------------------------------------------

    (vii) Finally, the taxpayer computes the compound category inflation 
index for Other fresh fruits as follows:

----------------------------------------------------------------------------------------------------------------
                                                                                                (III)  Compound
                                                           (I)  Category      (II)  Category        category
                          Item                            inflation index    inflation index    inflation index:
                                                          (second portion)   (first portion)        (I)*(II)
----------------------------------------------------------------------------------------------------------------
Other fresh fruits.....................................            1.0560             1.0210             1.0782
----------------------------------------------------------------------------------------------------------------

    (viii) The taxpayer may establish a new base year for the taxable 
year ending January 31, 2000.
    Example 2. BLS categories separated. (i) The facts are the same as 
in Example 1, except prior to October 1998, both lemons and peaches were 
assigned to ``Other fresh fruits'' and in the October 1998 CPI, the BLS 
created a new category, ``Citrus fruits,'' for citrus fruits, such as 
lemons. Moreover, the BLS reset the base-year BLS price index for 
``Other fresh fruits'' to 100.0 as of October 1, 1998. As a result of 
these changes, the taxpayer may no longer assign lemons to ``Other fresh 
fruits.'' (ii) Because ``Citrus fruits'' is new as of October 1998, the 
BLS did not publish a BLS price index for this BLS category in the 
January 1999 CPI. Thus, because the taxpayer cannot compute a category 
inflation index for ``Citrus fruits'' under the normal procedures, the 
taxpayer may compute a compound category inflation index for the 
affected BLS category using the procedures described in paragraph 
(e)(3)(iii)(D)(4)(ii) of this section.
    (iii) Based on the January 1999 CPI, the taxpayer assigns lemons to 
``Citrus fruits'' and peaches to ``Other fresh fruits.'' Then, the 
taxpayer computes a compound category inflation index for each of the 
two BLS categories. The computation of the category inflation index for 
the second portion is as follows:

----------------------------------------------------------------------------------------------------------------
                                                                       Jan. 1999 index/Sept.
              Item                          1999 category                  1998 index (as           Category
                                                                      published in Oct. 1998)   inflation index
----------------------------------------------------------------------------------------------------------------
Lemons.........................  Citrus fruits......................                 96.6/100             0.9660
Peaches........................  Other fresh fruits.................                105.6/100             1.0560
----------------------------------------------------------------------------------------------------------------


[[Page 538]]

    (iv) Then, the taxpayer computes the category inflation index for 
the first portion as follows:

----------------------------------------------------------------------------------------------------------------
                                                                      Sept. 1998 index (as
             Item                          1998 category            published in Sept. 1998)/ Category inflation

----------------------------------------------------------------------------------------------------------------

    (v) Finally, the taxpayer computes the compound category inflation 
index for ``Citrus fruits'' and ``Other fresh fruits'':

----------------------------------------------------------------------------------------------------------------
                                                                                                 (III)  Compound

                                                            (second portion)   (first portion)      (I)*(II)
----------------------------------------------------------------------------------------------------------------
Citrus fruits.............................................            0.9660            1.0162            0.9816
Other fresh fruits........................................            1.0560            1.0162            1.0731
----------------------------------------------------------------------------------------------------------------

    (vi) The taxpayer may establish a new base year for the taxable year 
ending January 31, 2000.

    (5) 10 percent method. (i) Applicability. A taxpayer that elects to 
use the 10 percent method described in paragraph (e)(3)(iii)(C)(2) of 
this section must compute a category inflation index for a less-detailed 
10 percent BLS category as provided in this paragraph (e)(3)(iii)(D)(5). 
A less-detailed 10 percent category is a BLS category that--
    (A) subsumes two or more BLS categories;
    (B) Does not have a single assigned item whose current-year cost is 
10 percent or more of the current-year cost of all the items in the 
dollar-value pool;
    (C) Has at least one item in at least one of the subsumed BLS 
categories; and
    (D) Has at least one subsumed BLS category that either does not have 
any assigned items or is a separate 10 percent BLS category.
    (ii) Determination of category inflation index. If the rules of this 
paragraph (e)(3)(iii)(D)(5) apply, the category inflation index for the 
less-detailed 10 percent BLS category is equal to the weighted 
arithmetic mean of the category inflation index (or, compound category 
inflation index, if applicable) for each of the subsumed BLS categories 
that have been assigned at least one item from the taxpayer's dollar-
value pool (excluding any item that is properly assigned to a separate 
10 percent BLS category). [Weighted Arithmetic Mean = Sum of (Weight x 
Category Inflation Index)]/Sum of Weights]. The appropriate weight for 
each of the most-detailed BLS categories referenced in the preceding 
sentence is the corresponding BLS weight. Currently, in January of each 
year, the BLS publishes the BLS weights determined for December of the 
preceding year. In the case of a taxpayer using the double-extension 
IPIC method, the BLS weights for December of the taxable year preceding 
the base year are to be used for all taxable years. In the case of a 
taxpayer using the link-chain IPIC method, the BLS weights for December 
of a given calendar year are to be used for taxable years that end 
during the 12-month period that begins on July 1 of the following 
calendar year. However, if the BLS weights are not published for all of 
the most-detailed BLS categories referenced above, the taxpayer may use 
the current-year cost (or in the case of a retailer using the retail 
method, the retail selling prices) of all items assigned to a specific 
most-detailed BLS category as the appropriate weight for that category, 
but must compute a weighted harmonic mean. See paragraph 
(e)(3)(iii)(E)(1) of this section for a formula of the weighted harmonic 
mean.
    (E) Computation of Inventory Price Index (IPI)--(1) Double-extension 
IPIC method. Under the double-extension IPIC method, the IPI for a 
dollar-value pool is the weighted harmonic mean of

[[Page 539]]

the category inflation indexes (or, if applicable, compound category 
inflation indexes) determined under paragraph (e)(3)(iii)(D) of this 
section for each selected BLS category (or, if applicable 10 percent BLS 
category) represented in the taxpayer's dollar-value pool at the end of 
the taxable year. The formula for computing the weighted harmonic mean 
of the category inflation indexes is: [Sum of Weights/Sum of (Weight/
Category Inflation Index)]. The weights to be used when computing this 
weighted harmonic mean are the current-year costs (or, in the case of a 
retailer using the retail method, the retail selling prices) in each 
selected BLS category represented in the dollar-value pool at the end of 
the taxable year.
    (2) Link-chain IPIC method. Under the link-chain IPIC method, the 
IPI for a dollar-value pool is the product of the weighted harmonic mean 
of the category inflation indexes (or, if applicable, the compound 
category inflation indexes) determined under paragraph (e)(3)(iii)(D) of 
this section for each selected BLS category (or, if applicable, 10 
percent BLS category) represented in the taxpayer's dollar-value pool at 
the end of the taxable year multiplied by the IPI for the immediately 
preceding taxable year. The formula for computing the weighted harmonic 
mean of the category inflation indexes is: [Sum of Weights/Sum of 
(Weight/Category Inflation Index)]. The weights to be used when 
computing this weighted harmonic mean are the current-year costs (or, in 
the case of a retailer using the retail method, the retail selling 
prices) in each selected BLS category represented in the dollar-value 
pool at the end of the taxable year.
    (3) Examples. The following examples illustrate the rules of this 
paragraph (e)(3)(iii)(E):

    Example 1. Double-extension method. (i) Introduction. R is a retail 
furniture merchant that does not use the retail method. For the taxable 
year ending December 31, 2000, R used the first-in, first-out method of 
identifying inventory and valued its inventory at cost. The total cost 
of R's inventory on December 31, 2000, was $850,000. R elected to use 
the dollar-value LIFO and double-extension IPIC methods for its taxable 
year ending December 31, 2001. R does not elect to use the 10 percent 
method described in paragraph (e)(3)(iii)(C)(2) of this section. R 
determines the current-year cost of the items using the actual cost of 
the most recently purchased goods. R elected to pool its inventory based 
on the major groups in Table 6 of the monthly ``PPI Detailed Report'' in 
accordance with the special IPIC pooling rules of paragraph (b)(4) of 
this section. All items in R's inventory fall within the 2-digit 
commodity code in Table 6 of the monthly ``PPI Detailed Report'' for 
``furniture and household durables.'' Therefore, R will maintain a 
single dollar-value pool. (ii) Select a BLS table and appropriate month 
for 2001. R determines that the appropriate month for 2001 is October. R 
also determines that the appropriate month for 2000 would have been 
December if R had used the IPIC method for that year.
    (iii) Assign inventory items to BLS categories for 2001. For 2001, R 
assigns all items in the dollar-value pool to the most-detailed BLS 
categories listed in Table 6 of the October 2001 ``PPI Detailed Report'' 
that contain those items. The BLS categories and the current-year cost 
of the items assigned to them are summarized as follows:

----------------------------------------------------------------------------------------------------------------
                                                                                                  Current-year
                 Commodity code                                     Category                          cost

    (iv) Compute category inflation indexes for 2001. Because R elected 
to use the double-extension IPIC method and did not elect the 10 percent 
method, the category inflation indexes are computed in accordance with 
paragraph (e)(3)(iii)(D)(3)(ii) of this section (BLS price indexes for 
October 2001 divided by BLS price indexes for December 2000). R computes 
the category inflation indexes for 2001 as follows:

    (v) Compute IPI for 2001. R must compute the IPI for 2001, which is 
the weighted harmonic mean of the category inflation indexes for 2001. 
The formula for the weighted harmonic mean provided in paragraph 
(e)(3)(iii)(E)(1) of this section is [Sum of Weights/Sum of (Weight/
Category Inflation Index)]. The IPI for 2001 is computed as follows:

----------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------

    (vi) Determine the LIFO value of the dollar-value pool for 2001. For 
2001, R determines the total base-year cost of its ending inventory by 
dividing the total current-year cost of the items in the dollar-value 
pool by the IPI for 2001. The total base-year cost of R's ending 
inventory is $908,355.80 ($921,380/1.01433821). Comparing the base-year 
cost of the ending inventory to the base-year cost of the beginning 
inventory, R determines that the base-year cost of the 2001 increment is 
$58,355.80 ($908,355.80 - $850,000.00). R multiplies the base-year cost 
of the 2001 increment by the IPI for 2001 and determines that the LIFO 
value of the 2001 layer is $59,192.52 ($58,355.80 * 1.01433821). Thus, 
the LIFO value of R's total inventory at the end of 2001 is $909,192.52 
($850,000.00 (opening inventory) + $59,192.52 (2001 layer)).
    (vii) Select a BLS table and appropriate month for 2002. For 2002, R 
must compute a new IPI under the double-extension IPIC method to 
determine the LIFO value of its dollar-value pool. R determines that the 
appropriate month for 2002 is November.
    (viii) Assign inventory items to BLS categories for 2002. For 2002, 
R assigns all items in the dollar-value pool to the most-detailed BLS 
categories listed in Table 6 of the November 2002 ``PPI Detailed 
Report'' that contain those items. The BLS categories and the current-
year cost of the items assigned to them are summarized as follows:

the category inflation indexes are computed in accordance with paragraph 
(e)(3)(iii)(D)(3)(ii) of this section (BLS price indexes for November

----------------------------------------------------------------------------------------------------------------

    (xi) Determine the LIFO value of the pool for 2002. For 2002, R 
determines the total base-year cost of its ending inventory by dividing 
the total current-year cost of the items in the dollar-value pool by the 
IPI for 2002. The total base-year cost of the ending inventory is 
$916,441.28 ($951,743.00/1.03852044). Comparing the base-year cost of 
the ending inventory to the base-year cost of the beginning inventory, R 
determines that the base-year cost of the 2002 increment is $8,085.48 
($916,441.28-$908,355.80). R multiplies the base-year cost of the 2002 
increment by the IPI for 2002 and determines that the LIFO value of the 
2002 layer is $8,396.94 ($8,085.48 * 1.03852044). Thus, the LIFO value 
of R's total inventory at the end of 2002 is $917,589.46 ($850,000.00 
(opening inventory) + $59,192.52 (2001 layer) + $8,396.94 (2002 layer)).
    Example 2. Link-chain method. (i) Introduction. The facts are the 
same as Example 1, except that R uses the link-chain IPIC method. The 
double-extension IPIC method and the link-chain IPIC method yield the 
same results for the first taxable year in which the dollar-value LIFO 
and IPIC methods are used. Therefore, this example illustrates only how 
R will compute the IPI for, and determine the LIFO value of, its dollar-
value pool for 2002. (ii) Select a BLS table and appropriate month for 
2002. R determines that the appropriate month for 2002 is November.
    (iii) Assign inventory items to BLS categories for 2002. For 2002, R 
assigns all items in the dollar-value pool to the most-detailed BLS 
categories listed in Table 6 of the November 2002 ``PPI Detailed 
Report'' that contain those items. The BLS categories and the current-
year cost of the items assigned to them are summarized as follows:

    (vi) Determine the LIFO value of the pool for 2002. R determines the 
total base-year cost of its ending inventory by dividing the total 
current-year cost of the items in the dollar-value pool by the IPI for 
2002. The total base-year cost of the ending inventory is $915,313.91 
($951,743.00 / 1.03979956). Comparing the base-year cost of the ending 
inventory to the base-year cost of the beginning inventory, R determines 
that the base-year cost of the 2002 layer is $6,958.11 ($915,313.91-
$908,355.80). R multiplies the base-year cost of the 2002 layer by the 
IPI for 2002 and determines that the LIFO value of the 2002 layer is 
$7,235.04 ($6,958.11 * 1.03979956). Thus, the LIFO value of R's total 
inventory at the end of 2002 is $916,427.56 ($850,000.00 (opening 
inventory) + $59,192.52 (2001 layer) + $7,235.04 (2002 layer)).

    (iv) Adoption or change of method--(A) Adoption or change to IPIC 
method. The use of an inventory price index computed under the IPIC 
method is a method of accounting. A taxpayer permitted to adopt the 
dollar-value LIFO method without first securing the Commissioner's 
consent also may adopt the IPIC method without first securing the 
Commissioner's consent. The IPIC method may be adopted and used, 
however, only if the taxpayer provides the following information on a 
Form 970, ``Application to Use LIFO Inventory Method,'' or in another 
manner as may be acceptable to the Commissioner: A complete list of 
dollar-value pools (including a description of the items in each dollar-
value pool); the BLS table (i.e., CPI or PPI) selected for each dollar-
value pool; the representative month, if applicable, elected for each 
dollar-value pool; the BLS categories to which the items in each dollar-
value pool will be assigned; the method of assigning items to BLS 
categories (e.g., the 10 percent method) for each dollar-value pool; and 
the method

[[Page 543]]

of computing the IPI (i.e., double-extension IPIC method or link-chain 
IPIC method) for each dollar-value pool. In the case of a taxpayer 
permitted to adopt the IPIC method without requesting the Commissioner's 
consent, the Form 970 must be attached to the taxpayer's income tax 
return for the taxable year of adoption. In all other cases, a taxpayer 
may change to the IPIC method only after securing the Commissioner's 
consent as provided in Sec. 1.446-1(e). In these latter cases, the Form 
970 containing the information described in this paragraph (e)(3)(iv)(A) 
must be attached to a Form 3115, ``Application for Change in Accounting 
Method,'' filed as required by Sec. 1.446-1(e). A taxpayer that 
simultaneously changes to the dollar-value LIFO and IPIC methods from 
another LIFO method must apply the rules of paragraph (f)(2) of this 
section before applying the rules of paragraph (e)(3)(iv)(B)(1) of this 
section. To satisfy the requirements of Sec. 1.472-2(h), taxpayers must 
maintain adequate books and records, including those concerning the use 
of the IPIC method and necessary computations. Notwithstanding the rules 
in paragraph (e)(1) of this section, a taxpayer that adopts, or changes 
to, the link-chain IPIC method is not required to demonstrate that the 
use of any other method of determining the LIFO value of a dollar-value 
pool is impractical.
    (B) New base year--(1) Voluntary change--(i) In general. In the case 
of a taxpayer using a non-IPIC method to determine the LIFO value of 
inventory, the layers previously determined under that method, if any, 
and the LIFO values of those layers are retained if the taxpayer 
voluntarily changes to the IPIC method. Instead of using the earliest 
taxable year for which the taxpayer adopted the LIFO method for any 
items in the dollar-value pool, the year of change is used as the new 
base year for the purpose of determining the amount of increments and 
liquidations, if any, for the year of change and subsequent taxable 
years. The base-year cost of the layers in a dollar-value pool at the 
beginning of the year of change must be restated in terms of new base-
year cost using the year of change as the new base year and, if 
applicable, the indexes for the previously determined layers must be 
recomputed accordingly. The recomputed indexes will be used to determine 
the LIFO value of subsequent liquidations. For purposes of computing an 
IPI under paragraph (e)(3)(iii)(E) of this section, the IPI for the 
immediately preceding year is 1.00. The new total base-year cost of the 
items in a dollar-value pool for the purpose of determining future 
increments and liquidations is equal to the total current-year cost of 
the items in the dollar-value pool (determined using the taxpayer's 
method of determining the total current-year cost of the items in the 
dollar-value pool under paragraph (e)(2)(ii) of this section). A 
taxpayer must allocate this new total base-year cost to each layer based 
on the ratio of the old base-year cost of the layer to the old total 
base-year cost of the dollar-value pool.
    (ii) Example. The following example illustrates the rules of this 
paragraph (e)(3)(iv)(B)(1):

    Example. (i) In 1990, X elected to use a dollar-value LIFO method 
(other than the IPIC method) for its single dollar-value pool. X is 
granted permission to change to the link-chain IPIC method, beginning 
with the taxable year ending December 31, 2001. X will continue using a 
single dollar-value pool. X's beginning inventory as of January 1, 2001, 
computed using its former inventory method, is as follows:

----------------------------------------------------------------------------------------------------------------
                                                                                                   (III)  LIFO

[[Page 544]]

    (ii) Under X's method of determining the current-year cost of items 
in a dollar-value pool, the current-year cost of the beginning inventory 
is $391,000. Thus, X's new base-year cost as of January 1, 2001, is 
$391,000. X allocates this new base-year cost to each layer based on the 
ratio of old base-year cost of the layer to the total old base-year cost 
of the dollar-value pool. To recompute the inflation indexes for each of 
its layers, X divides the LIFO value of each layer by the new base-year 
cost attributable to the layer. The new base-year cost, recomputed 
inflation indexes, and LIFO value of X's layers as of January 1, 2001, 
are as follows:

    (iii) In 2001, the current-year cost of X's ending inventory is 
$430,139. The weighted harmonic mean of the category inflation indexes 
applicable to X's ending inventory is 1.075347, and in accordance with 
paragraph (e)(3)(iv)(B)(1)(i) of this section, the inflation index for 
the immediately preceding taxable year is 1.00. Thus, X's IPI for 2001 
is 1.075347 (1.00 * 1.075347). The total base-year cost of X's ending 
inventory is $400,000 ($430,139/1.075347). The base-year cost, IPI, and 
LIFO value of X's layers as of December 31, 2001, are as follows:

    (iv) In 2002, the current-year cost of X's ending inventory is 
$418,000. The weighted harmonic mean of the category inflation indexes 
applicable to X's ending inventory is 1.02292562, and the IPI for the 
immediately preceding year is 1.075347. Thus, X's IPI for 2001 is 1.10 
(1.075347 * 1.02292562). The total base-year cost of X's ending 
inventory is $380,000 ($418,000/1.10), which results in a liquidation of 
$20,000 ($400,000-$380,000) in terms of base-year cost. This liquidation 
eliminates the 2001 layer ($9,000 base-year cost), the 1997 layer 
($3,400 base-year cost), and part of the 1995 layer ($7,600 base-year 
cost). The base-year cost, indexes, and LIFO value of X's layers as of 
December 31, 2002, are as follows:

    (2) Involuntary change--(i) In general. If a taxpayer uses a non-
IPIC method to compute the LIFO value of a dollar-value pool, and if the 
Commissioner determines that the taxpayer's method does not clearly 
reflect income, the

[[Page 545]]

Commissioner may require the taxpayer to change to the IPIC method. If 
the Commissioner requires a taxpayer to change to the IPIC method, and 
the taxpayer does not provide sufficient information from its books and 
records to compute an adjustment under section 481, the Commissioner may 
implement the change using the simplified transition method described in 
paragraph (e)(3)(iv)(B)(2)(ii) of this section.
    (ii) Simplified Transition Method. Under the simplified transition 
method, the Commissioner will recompute the LIFO value of each dollar-
value pool as of the beginning of the year of change using the double-
extension IPIC method or the link-chain IPIC method. The adjustment 
under section 481 is equal to the difference between the recomputed LIFO 
value and the LIFO value of the pool determined under the taxpayer's 
former method. The Commissioner will compute an IPI using the double-
extension IPIC method or link-chain IPIC method for each taxable year in 
which the LIFO method was used by the taxpayer based on the assumptions 
that the ending inventory of the pool in each taxable year was comprised 
of items that fall into the same BLS categories as the items in the 
ending inventory of the year of change and that the relative weights of 
those BLS categories in all prior years were the same as the relative 
weights of those BLS categories in the ending inventory of the year of 
change. The base-year cost of the items in a dollar-value pool at the 
end of a taxable year will be determined by dividing the IPI computed 
for the taxable year into the current-year cost of the items in that 
pool determined in accordance with paragraph (e)(2)(ii) of this section. 
If the comparison of the base-year cost of the beginning and ending 
inventory produces a current-year increment, the base-year cost of that 
increment will be multiplied by the IPI computed for that taxable year 
to determine the LIFO value of that layer.
    (iii) Example. The following example illustrates the rules of this 
paragraph (e)(3)(iv)(B)(2)(ii).

    Example. (i) Z began using a dollar-value LIFO method other than the 
IPIC method in the taxable year ending December 31, 1998, and maintains 
a single dollar-value pool. Z's beginning inventory as of January 1, 
2000, computed using its method of accounting, was as follows:

----------------------------------------------------------------------------------------------------------------
                                                             (I)  Base-year    (II)  Inflation     (III)  LIFO
                           Layer                                  cost              index       value:  (I)*(II)

    Total.................................................           108,000  ................           109,200
----------------------------------------------------------------------------------------------------------------

    (ii) Upon examining Z's federal income tax return for the taxable 
year ending December 31, 2000, the examining agent determines that Z's 
dollar-value LIFO method does not clearly reflect income. The examining 
agent chooses to change Z to the double-extension IPIC method for 2000 
and implements the change using the simplified transition method as 
follows. First, the inventory in Z's dollar-value pool at the end of 
2000 is assigned to the most-detailed categories in the CPI or PPI, 
whichever is appropriate. Assume that 80 percent of the current-year 
cost of Z's inventory as of December 31, 2000, is assigned to Category 
1, 10 percent is assigned to Category 2, and 10 percent is assigned to 
Category 3. Assume further that the current-year cost of the inventory 
in Z's dollar-value pool at the end of 1998 and 1999 was $133,000 and 
$145,000, respectively.
    (iii) The category inflation indexes for 1998 computed under the 
double-extension IPIC method are 1.17 for Category 1, 1.26 for Category 
2, and 1.19 for Category 3. The weights to be used in computing the IPI 
for 1998 are $106,400 ($133,000 * 80 percent) for Category 1, $13,300 
($133,000 * 10 percent) for Category 2, and $13,300 ($133,000 * 10 
percent) for Category 3. The IPI for 1998 is computed as follows:

----------------------------------------------------------------------------------------------------------------
                                                                               (II)  Category   (III)  Quotient:

    (iv) The base-year cost of the inventory in Z's pool at the end of 
1998 is $112,672 ($133,000/1.180417), and the base-year cost of the 1998 
increment is $7,672 ($112,672-$105,000). The LIFO value of the 1998 
layer is $9,056 ($7,672x1.180417).
    (v) The category inflation indexes for 1999 computed under the 
double-extension IPIC method were 1.21 for Category 1, 1.29 for Category 
2 and 1.23 for Category 3. The weights to be used in computing the IPI 
for 1999 are $116,000 ($145,000x80 percent) for Category 1, $14,500 
($145,000x10 percent) for Category 2, and $14,500 ($145,000x10 percent)

    (vi) The base-year cost of the inventory in Z's pool at the end of

    (viii) The section 481(a) adjustment is equal to the difference 
between the LIFO value of the inventory at the beginning of 2000 
computed under Z's former method of accounting and recomputed by the 
examining agent under the double-extension IPIC method, or $12,448 
($121,648--$109,200).
    (ix) Finally, the examining agent will recompute Z's taxable income 
for 2000 and succeeding taxable years using the double-extension IPIC 
method.

    (v) Effective date--(A) In general. The rules of this paragraph 
(e)(3) and paragraphs (b)(4) and (c)(2) of this section are applicable 
for taxable years ending on or after December 31, 2001.
    (B) Change in method of accounting. Any change in a taxpayer's 
method of accounting necessary to comply with this paragraph (e)(3) or 
with paragraphs (b)(4) or (c)(2) of this section is

[[Page 547]]

a change in method of accounting to which the provisions of section 446 
and the regulations thereunder apply. For the first or second taxable 
year ending on or after December 31, 2001, a taxpayer is granted the 
consent of the Commissioner to change its method of accounting to a 
method required or permitted by this paragraph (e)(3) and paragraphs 
(b)(4) and (c)(2) of this section. A taxpayer that wants to change its 
method of accounting under this paragraph (e)(3)(v) must follow the 
automatic consent procedures in Rev. Proc. 2002-9 (2002-3 I.R.B. xxx) 
(see Sec. 601.601(d)(2) of this chapter). However, the scope 
limitations in section 4.02 of Rev. Proc. 2002-9 do not apply, and the 
five-year limitation on the readoption of the LIFO method under section 
10.01(2) of the Appendix is waived. In addition, if the taxpayer's 
method of accounting for its LIFO inventories is an issue under 
consideration at the time the application is filed with the national 
office, the audit protection of section 7 of Rev. Proc. 2002-9 does not 
apply. If a taxpayer changing its method of accounting under this 
paragraph (e)(3)(v)(B) is under examination, before an appeals office, 
or before a federal court with respect to any income tax issue, the 
taxpayer must provide a copy of the application to the examining 
agent(s), appeals officer or counsel for the government, as appropriate, 
at the same time it files the application with the national office. Any 
change under this paragraph (e)(3)(v)(B) must be made using a cut-off 
method and new base year. See paragraph (e)(3)(iv)(B)(1) of this section 
for an example of this computation. Because a change under this 
paragraph (e)(3)(v)(B) is made using a cut-off method, a section 481(a) 
adjustment is not permitted. However, a taxpayer changing its method of 
accounting under this paragraph (e)(3)(v)(B) must comply with the 
requirements of section 10.06(3) of the APPENDIX of Rev. Proc. 2002-9 
(concerning bargain purchases).
    (f) Change to dollar-value method from another method of pricing 
LIFO inventories--(1) Consent required. Except as provided in Sec. 
1.472-3 in the case of a taxpayer electing to use a LIFO inventory 
method for the first time, or in the case of a taxpayer changing to the 
dollar-value method and continuing to use the same pools as were used 
under another LIFO method, a taxpayer using another LIFO method of 
pricing inventories may not change to the dollar-value method of pricing 
such inventories unless he first secures the consent of the Commissioner 
in accordance with paragraph (e) of Sec. 1.446-1.
    (2) Method of converting inventory. Where the taxpayer changes from 
one method of pricing LIFO inventories to the dollar-value method, the 
ending LIFO inventory for the taxable year immediately preceding the 
year of change shall be converted to the dollar-value LIFO method. This 
is done to establish the base-year cost for subsequent calculations. 
Thus, if the taxpayer was previously valuing LIFO inventories on the 
specific goods method, these separate values shall be combined into 
appropriate pools. For this purpose, the base year for the pool shall be 
the earliest taxable year for which the LIFO inventory method had been 
adopted for any item in that pool. No change will be made in the overall 
LIFO value of the opening inventory for the year of change as a result 
of the conversion, and that inventory will merely be restated in the 
manner used under the dollar-value method. All layers of increment for 
such inventory must be retained, except that all layers of increment 
which occurred in the same taxable year must be combined. The following 
examples illustrate the provisions of this subparagraph:

    Example (1). (i) Assume that the taxpayer has used another LIFO 
method for finished goods since 1954 and has complied with all the 
requirements prerequisite for a change to the dollar-value method. Items 
A, B, and C, which have previously been inventoried under the specific 
goods LIFO method, may properly be included in a single dollar-value 
LIFO pool. The LIFO inventory value of items A, B, and C at December 31, 
1960, is $12,200, computed as follows:

------------------------------------------------------------------------

There were no increments in the years 1957, 1958, or 1959.
    (ii) The computation of the ratio of the total current-year cost to 
the total base-year cost for the base year and each layer of increment 
in Pool No. 1 is shown as follows:

    (iii) On the basis of the foregoing computations, the LIFO inventory 
of Pool No. 1, at December 31, 1960, is restated as follows:

    Example (2). Assume the same facts as in example (1) and assume 
further that the base-year cost of Pool No. 1 at December 31, 1961, is 
$8,350. Since the closing inventory for the taxable year 1961 at base-
year cost is less than the opening inventory for that year at base-year 
cost, a liquidation has occurred during 1961. This liquidation absorbs 
all of the 1960 layer of increment and part of the 1956 layer of 
increment. The December 31, 1961, inventory is $10,131, computed as 
follows:

------------------------------------------------------------------------

    (g) Transitional rules--(1) Change in method of pooling. Any method 
of pooling authorized by this section and used by the taxpayer in 
computing his LIFO inventories under the dollar-value method shall be 
treated as a method of accounting. Any method of pooling which is 
authorized by this section

shall be used for the year of adoption and for all subsequent taxable 
years unless a change is required by the Commissioner in order to 
clearly reflect income, or unless permission to change is granted by the 
Commissioner as provided in paragraph (e) of Sec. 1.446-1. Where the 
taxpayer changes from one method of pooling to another method of pooling 
permitted by this section, the ending LIFO inventory for the taxable 
year preceding the year of change shall be restated under the new method 
of pooling.
    (2) Manner of combining or separating dollar-value pools. (i) A 
taxpayer who has been using the dollar-value LIFO method and who is 
permitted or required to change his method of pooling, shall combine or 
separate the LIFO value of his inventory for the base year and each 
yearly layer of increment in order to conform to the new pool or pools. 
Each yearly layer of increment in the new pool or pools must be 
separately accounted for and a record thereof maintained, and any 
liquidation occurring in the new pool or pools subsequent to the 
formation thereof shall be treated in the same manner as if the new pool 
or pools had existed from the date the taxpayer first adopted the LIFO 
inventory method. The combination or separation of the LIFO value of his 
inventory for the base year and each yearly layer of increment shall be 
made in accordance with the appropriate method set forth in this 
subparagraph, unless the use of a different method is approved by the 
Commissioner.
    (ii) Where the taxpayer is permitted or required to separate a pool 
into more than one pool, the separation shall be made in the following 
manner: First, each item in the former pool shall be placed in an 
appropriate new pool. Every item in each new pool is then extended at 
its base-year unit cost and the extensions are totaled. Each total is 
the amount of inventory for each new pool expressed in terms of base-
year cost. Then a ratio of the total base-year cost of each new pool to 
the base-year cost of the former pool is computed. The resulting ratio 
is applied to the amount of inventory for the base year and each yearly 
layer of increment of the former pool to obtain an allocation to each 
new pool of the base-year inventory of the former pool and subsequent 
layers of increment thereof. The foregoing may be illustrated by the 
following example of a change for the taxable year 1961:

    Example. (a) Assume that items A, B, C, and D are all grouped 
together in one pool prior to December 31, 1960. The LIFO inventory 
value at December 31, 1960, is computed as follows:

respective base-year unit costs is as follows:

    (c) Under the provisions of this section the taxpayer separates 
former Pool ABCD into two pools, Pool AB and Pool CD. The computation of 
the ratio of total base-year cost for each of the new pools to the base-
year cost of the former pool is as follows:

    (d) The ratio of the base-year cost of new Pools AB and CD to the 
base-year cost of former Pool ABCD is 7,000/20,000 and 13,000/20,000, 
respectively. The allocation of the January 1, 1956 base cost and 
subsequent yearly layers of increment of former Pool ABCD to new Pools 
AB and CD is as follows:

    (iii) Where the taxpayer is permitted or required to combine two or 
more pools having the same base year, they shall be combined into one 
pool in the following manner: The LIFO value of the base-year inventory 
of each of the former pools is combined to obtain a LIFO value of the 
base-year inventory for the new pool. Then, any layers of increment in 
the various pools which occurred in the same taxable year are combined 
into one total layer of increment for that taxable year. However, layers 
of increment which occurred in different taxable years may not be 
combined. In combining the layers of increment a new ratio of current-
year cost to base-year cost is computed for each of the combined layers 
of increment. The foregoing may be illustrated by the following example:

    Example. (a) Assume the taxpayer has two pools at December 31, 1960. 
Under the provisions of this section the taxpayer combines these pools 
into a single pool as of January 1, 1961. The LIFO inventory value of 
each pool at December 31, 1960, is shown as follows:

    (iv) In combining pools having different base years, the principles 
set forth in subdivision (iii) of this subparagraph are to be applied, 
except that all base years subsequent to the earliest base year shall be 
treated as increments, and the base-year costs for all pools having a 
base year subsequent to the earliest base year of any pool shall be 
redetermined in terms of the base cost for the earliest base year. The 
foregoing may be illustrated by the following example:

    Example. (a) Assume that the taxpayer has two pools at December 31, 
1960. Under the provisions of this section the taxpayer combines these 
pools into a single pool as of January 1, 1961. The LIFO inventory value 
of each pool at December 31, 1960, is shown as follows:

------------------------------------------------------------------------

    (b) The next step is to redetermine the 1958 base-year cost for Pool 
No. 2 in terms of 1956 base-year cost. January 1, 1956 base-year unit 
cost must be reconstructed or established in accordance with paragraph 
(e)(2) of this section for each item in Pool No. 2. Such costs are 
assumed to be $9.00 for item A, $20.00 for item B, and $1.80 for item C. 
A ratio of the 1958 total base-year cost to the 1956 total base-year 
cost for Pool No. 2 is computed as follows:

      Total...............................  ........  ........     5,000
------------------------------------------------------------------------

    (c) The ratio of the 1956 total base-year cost to the 1958 total 
base-year cost for Pool No. 2 is 4,650/5,000 or 93 percent. The January 
1, 1958 base cost and each yearly layer of increment at 1958 base-year 
cost is multiplied by this ratio. Such computation is as follows:

    (3) Change in methods of computation at the LIFO value of a dollar-
value pool. For the first taxable year beginning after December 31, 
1960, the taxpayer must use a method authorized by paragraph (e)(1) of 
this section in computing the base-year cost and current-year cost of a 
dollar-value inventory pool for the end of such year. If the taxpayer 
had previously used any methods other than one authorized by paragraph 
(e)(1) of this section, he shall not be required to recompute his LIFO 
inventories for taxable years beginning on or before December 31, 1960, 
under a method authorized by such paragraph. The base cost and layers of 
increment previously computed by such other method shall be retained and 
treated as if such base cost and layers of increment had been computed 
under a method authorized by paragraph (e)(1) of this section. The 
taxpayer shall use the year of change as the base year in applying the 
double-extension method or other method approved by the Commissioner, 
instead of the earliest year for which he adopted the LIFO method for 
any items in the pool.
    (h) LIFO inventories received in certain nonrecognition 
transactions--(1) In general. Except as provided in paragraph (h)(3) of 
this section, if inventory items accounted for under the LIFO method are 
received in a transaction described in paragraph (h)(2) of this section, 
then, for the purpose of determining future increments and liquidations, 
the transferee must use the year of transfer as the base year and must 
use its current-year cost (computed under the transferee's method of 
accounting) of those items as their new base-year cost. If the 
transferee had opening inventories in the year of transfer, then, for 
the purpose of determining future increments and liquidations, the 
transferee must use its current-year cost (computed under the 
transferee's method of accounting) of those inventories as their new 
base-year cost. For this purpose, ``opening inventory'' refers to all 
items owned by the transferee before the transfer for which the 
transferee uses, or elects to use, the LIFO method. The total new base-
year cost of the transferee's inventory as of the beginning of the year 
of transfer is equal to the new base-year cost of the inventory received 
from the transferor and the new base-year cost of the transferee's 
opening inventory. The index (or, the cumulative index in the case of 
the link-chain method) for the year immediately preceding the year of 
transfer is 1.00. The base-year cost of any layers in the dollar-value 
pool, as

[[Page 553]]

determined after the transfer, must be recomputed accordingly. See 
paragraph (e)(3)(iv)(B)(1) of this section for an example of this 
computation.
    (2) Transactions to which this paragraph (h) applies. The rules in 
this paragraph (h) apply to a transaction in which--
    (i) The transferee determines its basis in the inventories, in whole 
or in part, by reference to the basis of the inventories in the hands of 
the transferor;
    (ii) The transferor used the dollar-value LIFO method to account for 
the transferred inventories;
    (iii) The transferee uses the dollar-value LIFO method to account 
for the inventories in the year of the transfer; and
    (iv) The transaction is not described in section 381(a).
    (3) Anti-avoidance rule. The rules in this paragraph (h) do not 
apply to a transaction entered into with the principal purpose to avail 
the transferee of a method of accounting that would be unavailable to 
the transferor (or would be unavailable to the transferor without 
securing consent from the Commissioner). In determining the principal 
purpose of a transfer, consideration will be given to all of the facts 
and circumstances. However, a transfer is deemed made with the principal 
purpose to avail the transferee of a method of accounting that would be 
unavailable to the transferor without securing consent from the 
Commissioner if the transferor acquired inventory in a bargain purchase 
within the five taxable years preceding the year of the transfer and 
used a dollar-value LIFO method to account for that inventory that did 
not treat the bargain purchase inventory and physically identical 
inventory acquired at market prices as separate items. Inventory is 
deemed acquired in a bargain purchase if the actual cost of the 
inventory (or, if appropriate, the allocated cost of the inventory) was 
less than or equal to 50 percent of the replacement cost of physically 
identical inventory. Inventory is not considered acquired in a bargain 
purchase if the actual cost of the inventory (or, if appropriate, the 
allocated cost of the inventory) was greater than or equal to 75 percent 
of the replacement cost of physically identical inventory.
    (4) Effective date. The rules of this paragraph (h) are applicable 
for transfers that occur during a taxable year ending on or after 
December 31, 2001.
