The departments which were not placed upon a Lifo basis constituted about 5 per cent of petitioner's inventory.

Petitioner's merchandise inventory as of January 31, 1941, shown on its income tax return for the fiscal year ended in 1942, which respondent has not sought to adjust, was as follows:

Attached to its 1942 income tax return was an exhibit, "Calculation of Last in First Out Inventory," but the discovery of certain errors after commencement of the hearing and a change in method of computing Lifo inventory for certain departments1947 U.S. Tax Ct. LEXIS 318">*324 led petitioner to present a corrected calculation, designated as Exhibit 12.

The first ten columns of that exhibit set out the department by number, and the cost, retail price, and percentage of mark-on for each department, segregated for opening and closing inventory dates and year's purchases. The figures so appearing are hereby found accordingly.

The corrected calculation was incomplete, in that it was prepared prior to discovery of an error in the index figure for National Industrial Conference Board Department 62, the corrected figure for that department being 116.56, instead of 117.44, which latter figure was used by petitioner. This correction has caused an increase of $ 714.88 in the amount of Lifo inventory as computed by petitioner.

On its financial statement as of the close of business January 31, 8 T.C. 14">*17 1942, petitioner stated its inventory as computed under its procedure of applying the Lifo method:

8 T.C. 14">*18 The following is the procedure employed by petitioner in the computation of what it designates as its Lifo inventory:

(1) The retail value of the inventory of each department as at January 31, 1942, is reduced by certain percentages which are designed to represent the percentage of the average price rise in retail prices between January 31, 1941, and January 31, 1942, of goods carried in a typical department store. January 1941 is considered to be the base level, or 100 per cent, and the percentages there shown are relative 8 T.C. 14">*19 thereto and were computed as a result of a study undertaken by the National Industrial Conference Board, more fully described hereinafter. This reduced amount is claimed to represent the retail value of the department inventory at January 31, 1942, computed at the January 31, 1941, retail price level.

(2) The reduced amount is then compared with the retail value of the department inventory of the same department as at January 31, 1941.

(3) In those instances in which the adjusted total retail value of a department1947 U.S. Tax Ct. LEXIS 318">*326 inventory as at January 31, 1942, is less than the retail value of the inventory as at January 31, 1941, the amount of the decrease is reduced to cost by multiplying such amount by the complement of the department's mark on, and the product so derived is then subtracted from the opening inventory at cost; the remainder is then employed as the Lifo closing inventory of the department at January 31, 1942.

(4) In those instances in which the adjusted total retail value of the department inventory as at January 31, 1942, is in excess of the retail value of the department inventory as at January 31, 1941, the amount of the excess is readjusted to current selling prices by multiplying it by the department index figure for the increase in prices. The product, representing the retail price, is then reduced to cost by multiplying it by the complement of the department's mark-on for the year's purchases. This figure is added to the opening inventory at cost, and the sum is then employed as the Lifo closing inventory of the department at January 31, 1942.

The price rise percentage figures hereinbefore referred to were taken from a special report, entitled "Indexes of Change in Retail Prices1947 U.S. Tax Ct. LEXIS 318">*327 of Department Stores from January 31, 1941 Through January 31, 1942," prepared and published by the National Industrial Conference Board (hereinafter sometimes referred to as N. I. C. B. or the Board). This special report was prepared for the National Retail Dry Goods Association (hereinafter sometimes referred to as the Association), of which petitioner is a member.

The Association had the report prepared after studying ways and means of preventing inflated inventory figures in the balance sheets of department stores due to the effect of price rises following the outbreak of the war in Europe. The Association, which has 7,000 member stores in the United States and Canada, and one of its suborganizations, the Controllers' Congress, composed mainly of the financial men of department stores, decided that a satisfactory solution of the problem of inflated inventories would be the use of the Lifo method of inventory valuation.

8 T.C. 14">*20 Their suggestion for adoption of the Lifo method by member stores led to the problem of the manner of measuring the price change from year to year in the inventories of particular departments of a department store. Existing indices of various government1947 U.S. Tax Ct. LEXIS 318">*328 agencies, as well as of private agencies, were considered, but were deemed unsuitable. Some consideration was given to the creation of individual indices by each store, but the problems incident thereto, the cost, and the anticipated wider acceptability of a national index caused them to avoid that approach.

After reviewing the matter for several months, the Association decided to attempt to obtain a study of retail price changes of department stores from 1941 to 1942, and selected the N. I. C. B. to make it

Price changes were to be computed, department by department, as set up in the reports of the Controllers' Congress. This department classification is generally followed by department stores, and is used as the basis of statistical studies by government agencies. The names of departments of a department store are fairly descriptive of the merchandise content therein. The classification of departments being generally uniform in department store business, a description of a department by name would give to one familiar with department store business a conception of the general character of goods included in a particular department.

The N. I. C. B., founded in 1916, is a nonprofit, 1947 U.S. Tax Ct. LEXIS 318">*329 independent institution whose specific function is continuously to assembly, analyze, and present useful information regarding economic conditions and management experience in the United States and other countries. It publishes numerous periodicals and reports of its studies and activities, which are widely accepted and relied upon. It is supported and assisted by business organizations, labor unions, and government agencies.

The first step undertaken by the Board in the creation of its index of retail price changes was the selection of and specifications for representative items of merchandise. Conferences were held with buyers of the different departments, generally from five to fifteen being present, most of whom were attached to New York buying offices of individual stores or of paid buying organizations. In this selection process, departments were broken down into subgroups, and buyers were requested to select the principal article of the subgroup, which was usually done on the basis of sales. Other items were selected on the basis of the diversity of price movement.

After a number of articles believed to be representative of the price movements of all the goods in the various1947 U.S. Tax Ct. LEXIS 318">*330 departments were selected, a questionnaire was prepared and was sent to approximately 900 stores, 8 T.C. 14">*21 each having annual sales in excess of $ 500,000. The questionnaire contained a specification of the items selected by departments and sought answers to the value of inventories at retail, item by item as of January 31, 1941, and as of January 31, 1942, and retail prices as of the two dates. An additional column was provided to "indicate item reported if other than that designated." 713 items, classified into 52 departments, were covered. No index figure was computed, however, for one of the departments -- hardware -- as the data received were insufficient. Information was sought as to 33 items in that department; 72 other items were discarded because they were found to be of insufficient importance in store inventories to merit any weight. Estimated price changes in two departments: pet accessories, index figure, 113.84; and garden equipment, index figure, 107.67, were based on data which the Board itself considered incomplete.

Replies were received from 112 stores, located in 32 states. Petitioner submitted such questionnaires, designated herein as Exhibits E and F. These1947 U.S. Tax Ct. LEXIS 318">*331 show petitioner's retail prices for various items listed, as of January 31, 1941, and January 31, 1942. The material so appearing is hereby found accordingly.

Not all of the stores reported prices on all of the items, the maximum being 92 for any one item. Comparatively few stores, of which petitioner was not one, reported the inventory data requested in the questionnaire. The maximum number reporting inventory data for the fiscal year 1941 was 36; for the fiscal year 1942, 27.

Upon receipt of the replies, the Board's staff edited for comparability and for the purpose of discovering and eliminating any obvious errors. The reported prices of the respective items were then added and averaged for January 31, 1941, and January 31, 1942.

The inventory data as of those dates which were reported in some replies were next used for determining weights to be applied to the various sample commodities in the respective departments. The purpose was to ascertain the relative importance of such commodities in comparison with other goods in the same department, by reference to the comparative size of the inventory amounts of the respective commodities.

The Board determined that the formula to1947 U.S. Tax Ct. LEXIS 318">*332 be used in applying the weights to the price changes should be the so-called "Ideal Formula," popularized by Dr. Irving Fisher. This formula involves a cross weighting. The problem encountered here, reduced to its essence, was that of combining weights for the same commodity as of the opening and closing inventories. Use of the "Ideal Formula" has the effect of averaging the weights assigned to the commodity. Alternative methods are to employ only the weight as of one period or the other. 8 T.C. 14">*22 Respondent's witness was of the opinion that the so-called "Paasche's Formula," which uses only the weight at the end of the period, that is, that applicable to the closing inventory, would give a more satisfactory result than the "Ideal Formula."

An index was then computed, department by department. Certain errors were discovered and corrections made in the National Industrial Conference Board index after its publication.

The average rise for all departments, after correction, was found to be 115.69.

The index is designed to reflect price changes in a typical department store, and not in any particular store.

Department store business is highly standardized; and in department store1947 U.S. Tax Ct. LEXIS 318">*333 administration, comparisons made between stores throughout the country and statistical data of a general nature are used by department store management.

Petitioner has used the standard classification of departments, although it does use different numbers and in some instances has subdivided departments.

Comparison of the index figures for 14 of the 52 departments with index figures of the same departments of petitioner, using petitioner's prices and N. I. C. B. inventory weights, shows the following variations:

1947 U.S. Tax Ct. LEXIS 318">*334 A national index would differ from an individual store index, not only as to result, but also as to manner of procedure in eliciting information and in type and quantity of information available for statistical use, because the problems of constructing an individual store index differ from those incident to the construction of a national index.

The consumers' price index, formerly known as the cost of living index, prepared by the Bureau of Labor Statistics, Department of 8 T.C. 14">*23 Labor, showed index figures applicable to Baltimore, Maryland, as follows, the period 1935 to 1939 being considered as 100:

National and area index figures and those for other individual cities differed from those for the city of Baltimore. A comparison of the retail prices of clothing and house furnishings -- January 1942, relative to January 1941 -- reflected the following extreme differences among cities:

1947 U.S. Tax Ct. LEXIS 318">*335 The Bureau of Labor Statistics also publishes a "List of Items Included in the Cost of Living Index of the Bureau of Labor Statistics and Their Relative Importance at Various Dates (Revised April 1945)," in which appear the assigned weights of the various items, grouped under classifications of "Food," "Clothing," "Rent," "Fuel, electricity and ice," "Housefurnishing," and "Miscellaneous," which items and weights are utilized by the Bureau in developing its cost of living index. Among others, weights as of December 15, 1942, the date closest to the end of the taxable year herein involved, appear in the listing.

Petitioner's January 31, 1942, inventory at cost, as determined without the use of Lifo, is agreed to be $ 1,319,287.29.

In his notice of deficiency, respondent determined:

* * * that the "Last in-First out Method" of evaluating your inventory at the close of the taxable year is not in accordance with Section 22 (d) of the Internal Revenue Code and, therefore, your inventory is adjusted on the basis of the "Retail Method."

OPINION.

Although the subject matter of the present proceeding is complex and technical, its general purpose is one which can be simply stated in terms 1947 U.S. Tax Ct. LEXIS 318">*336 of everyday general experience. The central 8 T.C. 14">*24 problem is one dealing with inventories which, in the case of department stores, are kept by the use of a unit which is the dollar. When prices or costs are constant, any increase or decrease in the dollar amount will furnish a reasonably reliable measure of the increase or decrease in the physical inventory. But it is common and sometimes bitter experience that in a period of rising prices the same amount of dollars will represent a smaller physical volume of goods, and the same physical volume will be represented by a higher number of dollars. The fundamental proposition about which the present proceeding revolves is the possibility and desirability of eliminating from an inventory kept in dollars that part which represents not an increase in physical inventory, but merely an expanded dollar figure at which that inventory is being carried.

A review of the characteristics of the retail method of inventories is necessary to appreciate the genesis of the present problem. Because of the number and diversity of individual articles constituting the stock of the typical department store, a system has been devised, approved, ¹ and1947 U.S. Tax Ct. LEXIS 318">*337 generally practiced of reducing such articles to their lowest common denominator -- a dollar figure. The inventories are taken and carried over from year to year in that form, rather than by specific items or quantities. And the annual stock-taking process constituting the ascertainment of the physical inventory is likewise, because of the complications of recording and maintaining actual costs for a constantly fluctuating stock, permitted to be based on computation and averaging.

That process is, roughly, to take from the price tags of the merchandise in stock on the day of the closing inventory a total for each department which, of course, represents the retail price on that day of all the goods then on hand. From this there is deducted the department's average mark-on for the year, and the resulting figure, representing a theoretical conversion back to the cost of the goods on the shelves, is the closing1947 U.S. Tax Ct. LEXIS 318">*338 inventory of the department in question. ²

The mark-on or difference between the cost to the store and its selling price is obtained by recourse to the original invoices. During the year, as goods are received the invoices are extended by a notation of the retail price at which such goods are to be sold. These invoices form the records from which the mark-on for the year is computed by comparing the total of the costs they show with the total retail prices extended on them.

The dollar amount of the inventory so determined is then used like any other in computing the cost of goods sold, gross merchandising 8 T.C. 14">*25 profit, and ultimate net income of the store. The immediately apparent consequences of the retail method are that the goods in a single 1947 U.S. Tax Ct. LEXIS 318">*339 department are treated for inventory purposes as being entirely fungible, even though in fact they may, and generally do, differ considerably as to type, quality, and price. This follows from the fact that inventories are taken, entered, and maintained not in terms of individual items of merchandise, but only in the form of dollars, which are necessarily completely interchangeable. And also for the same reason, and what is perhaps a different method of saying the same thing, the problem of pricing the inventory, or more accurately, of "costing" it, has been eliminated, since the dollar figure arrived at as the make-up of the inventory is also taken as its cost without further conversion. A taxpayer who keeps his inventories in terms of specific items or quantities must convert them into dollars before they can be entered on the books and used in arriving at income. The retail method of inventories eliminates that intermediate step.

Petitioner's position is founded on the proposition that, in a period of consistently advancing price levels, the result is to show as a profit what is merely an increase in the retail price and hence in the apparent cost of its inventories. In order1947 U.S. Tax Ct. LEXIS 318">*340 to eliminate the consequent unrealized income, it claims to be entitled to the benefits of section 22 (d), added by the Revenue Act of 1939, which provides as follows:

(d) (1) A taxpayer may use the following method (whether or not such method has been prescribed under subsection (c)) in inventorying goods specified in the application required under paragraph (2):

(A) Inventory them at cost;

(B) Treat those remaining on hand at the close of the taxable year as being: First, those included in the opening inventory of the taxable year (in the order of acquisition) to the extent thereof, and second, those acquired in the taxable year; and

(C) Treat those included in the opening inventory of the taxable year in which such method is first used as having been acquired at the same time and determine their cost by the average cost method.

(2) The method described in paragraph (1) may be used --

(A) Only in inventorying goods (required under subsection (c) to be inventoried) specified in an application to use such method filed at such time and in such manner as the Commissioner may prescribe; and

(B) Only if the taxpayer establishes to the satisfaction of the Commissioner that the 1947 U.S. Tax Ct. LEXIS 318">*341 taxpayer has used no procedure other than that specified in subparagraphs (B) and (C) of paragraph (1) in inventorying (to ascertain income, profit, or loss, for credit purposes, or for the purpose of reports to shareholders, partners, or other proprietors, or to beneficiaries) such goods for any period beginning with or during the first taxable year for which the method described in paragraph (1) is to be used.

(3) The change to, and the use of, such method shall be in accordance with such regulations as the Commissioner, with the approval of the Secretary, may prescribe as necessary in order that the use of such method may clearly reflect income.

8 T.C. 14">*26 (4) In determining income for the taxable year preceding the taxable year for which such method is first used, the closing inventory of such preceding year of the goods specified in such application shall be at cost.

* * * *

Slight and presently immaterial amendments were made retroactively by section 118 of the Revenue Act of 1942.

The effect of this provision is to permit the use of a concept described as last in, first out in the determination of the contents of an inventory -- familiarly known and sometimes here referred1947 U.S. Tax Ct. LEXIS 318">*342 to as Lifo -- in place of a first in, first out, or Fifo, theory, without regard to whether the actual physical content of the inventory conforms to the assumptions so made. ³

A comparable provision appeared for the first time in the Revenue Act of 1938, but was there limited to special classes of taxpayers. ⁴

1947 U.S. Tax Ct. LEXIS 318">*343 In order to equip themselves to make the last in, first out method available, members of the National Retail Dry Goods Association, including petitioner, concluded that it was necessary to eliminate from the amount of their inventory taken at retail that portion which represented a rise in prices during the year. For the purpose of determining what this conversion factor would be, they employed the National Industrial Conference Board to make a nation-wide survey of relative prices in the member stores and to compute for each department a figure designed to represent the year's increase in retail prices in the standard departments of a typical store. The selection of appropriate sample items, the ascertainment of basic figures by means of questionnaires, the weighting and averaging, and the computation of the ultimate index numbers used are set forth in more detail in the 8 T.C. 14">*27 findings of fact and need not be repeated at this point. Employing the ultimate figures resulting, petitioner adjusted the dollar amounts of its inventories at retail accordingly, and thereupon computed cost from that reduced figure. It filed an application for, and claimed on its return for the taxable1947 U.S. Tax Ct. LEXIS 318">*344 year to be entitled to, this use of the Lifo method.

The conversion back to opening inventory price levels, computed by using the N. I. C. B. index figure, was confined to the quantity of goods, stated in terms of dollars, which was in the opening inventory. If any department showed a larger closing inventory, the difference would not be computed at the opening inventory price level, but at its actual retail price on the date of the closing inventory. An example of this operation, taken from petitioner's brief, is set forth in the margin. ⁵

1947 U.S. Tax Ct. LEXIS 318">*345 Respondent raises no question as to petitioner's compliance with the technical requirements of the section such as the filing of the necessary application and use of the system in its financial reports. The controversies calling for decision can be reduced to whether the statutory grant of leave to use the last in, first out method is applicable to a taxpayer maintaining inventories by use of the retail system; and, if so, what method represents a permissible means of securing the benefits of the section. But in arriving at an answer to the latter question, consideration of a number of alternative possibilities is not required.

8 T.C. 14">*28 Refined to its simplest terms, the fundamental question is whether the identification of specific articles in an inventory is the prerequisite for application of the last in, first out method. Respondent's contention that it is seems supported neither by logic nor by legislative intent. His principal reliance, the interpretative regulations, will not withstand examination. Those provisions most nearly dealing with the present question were inserted long after the tax year and, in fact, after the present proceeding had been brought to hearing. T. D. 5504, 1946-1 C. B. 52, 53.1947 U.S. Tax Ct. LEXIS 318">*346 Their retroactive application seems unwarranted. Helvering v. Reynolds Tobacco Co., 306 U.S. 110">306 U.S. 110. All of the regulations ⁶ are as consistent with petitioner's position as they are with that of respondent. See, e. g., Regulations 103, secs. 19.22 (c)-8 and 19.22 (d)-3. It is simpler and more rewarding to seek the meaning of the statute itself than of ambiguous and largely irrelevant administrative interpretations.

1947 U.S. Tax Ct. LEXIS 318">*347 As to the language of the statute, it is urged that the term "goods" is used advisedly and "in the common and ordinary sense." But the dictionary ⁷ gives as synonyms "wares and merchandise." Wares may have a slightly archaic flavor, but merchandise is a term in the day-to-day vernacular, and it is difficult to conjure up one more accurately describing in the generic sense the stock in trade of a typical department store.

It is true that the legislative history indicates agitation for the amendment which became section 22 (d) as having its origin among certain groups of producers for whose special problem the Lifo solution would be particularly appropriate. It is also indicated that in these instances taxpayers followed generally an inventory system which dealt with specific articles, and that they were faced also with 8 T.C. 14">*29 the problem of attributing a cost to the articles so ascertained. ⁸ But it does not follow from this that, when the statute was amended to1947 U.S. Tax Ct. LEXIS 318">*348 acquire its present all-embracing character, it was designed to cover only the industries which originally sought its enactment. The conclusion is rather to be drawn that, like all revenue legislation, particularly of a relief character, the purpose of the lawmakers was to have it apply in general terms to all those coming within its provisions. ⁹

Similar results have been sought under what is known as the "minimum," "cushion," "base stock," 1947 U.S. Tax Ct. LEXIS 318">*349 or "constant average" method of inventories. It has been insisted that such a process does violence to the principle of annual accounting periods, since it has the effect of postponing the profit in a high price year and absorbing it in a subsequent period of low prices. For that reason it was held that the minimum inventory method does not clearly reflect income even in a base stock industry such as a steel fabricator and builder which kept its inventory records in terms of tons. Kansas City Structural Steel Co., 11 B. T. A. 877; and see the same case on review, Lucas v. Kansas City Structural Steel Co., 281 U.S. 264">281 U.S. 264. It is, however, to precisely this type of taxpayer that apparently even respondent concedes the Lifo amendment embodied in section 22 (d) was directed. No such provision was in existence at the time the Kansas City Structural Steel Co. case was decided, and it must be accepted as the present legislative opinion that the broad doctrine for which that case stands is no longer authoritative. Unless we can discover some logical reason why the Lifo method, which is concededly available in these situations, 1947 U.S. Tax Ct. LEXIS 318">*350 is not equally applicable to inventories as to which ascertainment and valuation are a single process, the assumption seems to us required that petitioner may bring itself within the terms of section 22 (d) by conforming to its requirements.

We have already had occasion to note that the primary characteristic of inventories maintained under the retail method is the use of dollars as the measure of quantity. In a period of radically and rapidly changing price levels, the dollars so attributed to an inventory will be neither the current cost of replacement nor the presumptive level at which the inventory will be diminished by sales. But this is precisely the basic problem faced by the industries to which the legislation was concededly directed. The method of its application in those cases is simple, while with respect to such taxpayers as petitioner it is relatively complex. But, since the fundamental situation to which the provision is directed 8 T.C. 14">*30 is identical, and since no portion of its operation or language is inherently inapplicable, it should, if possible, be given effect in all cases presenting the problem with which it deals. It remains to be considered whether the1947 U.S. Tax Ct. LEXIS 318">*351 practical impediments to its application are so great as to eliminate the possibility of its use in such situations as that now before us.

The process envisaged by Lifo involves not so much the ascertainment of cost as the ascertainment of what it is of which we are to discover the cost. The last in, first out formula assumes that the merchandise remaining in the inventory is that which was first purchased. When that assumption is made, the process of ascertainment becomes difficult in the case of a retail merchant primarily because of the complications of the retail method itself.

If we were dealing with a fabricator or manufacturer, the first step would be to determine which merchandise it is to which a cost is to be attributed, and the second, to determine that cost. The corresponding process engaged in by petitioner is to reduce the price level of the retail stock to that prevailing as of the opening inventory, and thereby to identify the merchandise remaining in inventory at the close of the year as that constituting inventory at the beginning of the year to the extent of the size of the opening inventory. That this is done by dealing with the merchandise stated in terms 1947 U.S. Tax Ct. LEXIS 318">*352 of dollars rather than of numbers or quantities is a requisite of the aspect of department store accounting which relies for its inventory volume on a statement in dollars alone.

But it will not do to say that this method does not truly reflect a taxpayer's inventory or that the use of dollars instead of other measures of quantity has the effect of distorting the inventory content. The retail method has been used with respondent's complete approval for too long a time for the assumption to be permissible that the contents of an inventory can not be satisfactorily represented for all purposes by its expression in dollars only; or for the result to be acceptable, unless entirely necessary, that the use of that method for the statement of an inventory forecloses the user from other benefits.

Having identified the closing inventory as containing the carry-over merchandise from the opening inventory -- that is, making the assumption of Lifo that the latest purchases were the first sold and the earlier purchases remained on hand -- the process of putting a cost figure against the merchandise in a closing inventory as carried out on petitioner's present theory is simple. It calls merely1947 U.S. Tax Ct. LEXIS 318">*353 for the ascertainment of historic cost; in other words, it is the same cost which the same merchandise carried as of the opening inventory of the current year; and likewise, of course, the previous closing inventory. This is accomplished 8 T.C. 14">*31 by resorting to the inventory itself, which is habitually carried at two figures, retail and cost. That proportion of the total cost is taken which the goods remaining out of the opening inventory bear to the total opening inventory; or, identically, by applying to the remainder of the opening inventory at retail the mark-on resulting from comparing the retail and cost figures of that inventory.

A summary description of the process might thus be stated as ascertaining the quantity of merchandise in the closing inventory, which is the equivalent at comparable prices of that in the opening inventory; applying to that portion of the closing inventory its historic cost; and applying to the remainder its current cost computed by processes which have become traditional under the retail method. Merchandise which is assumed to have been in both inventories is accordingly handled at the cost of the opening inventory. Any decrease is treated as1947 U.S. Tax Ct. LEXIS 318">*354 having the same cost. Any increase is included at the cost of the current year's purchases.

It is difficult to see that in either of these necessary steps -- the selection of the merchandise constituting the inventory, or the assignment to that merchandise of a cost figure -- such violence is done to recognized principles of retail inventory practice as to demonstrate either from principle or application that Congress intended the Lifo provisions to be inapplicable to the accounting procedure of retail merchants. The computations involved may be somewhat extensive, but they lack neither adequate clarity nor logic, and they can not be discarded as unduly burdensome in the light of the permissive character of the statutory option. We conclude that adaptation of the Lifo theory to inventories maintained in terms of dollars through the approach generally employed by the present petitioner is permissible and proper within the provisions of section 22 (d).

One aspect of the mechanics resorted to by petitioner and other members of the Retail Dry Goods Association, however, requires further mention. That is the selection of an index figure to be applied in reconverting to opening inventory1947 U.S. Tax Ct. LEXIS 318">*355 prices. The record contains, in addition to the N. I. C. B. index, somewhat corresponding figures derived and published by a public body, the Bureau of Labor Statistics of the United States Department of Labor, not only for the Nation as a whole, but for individual cities, including Baltimore, in which this petitioner is located. It also contains material showing the weights attached by the Bureau of Labor Statistics to various items used to compute its index and which are found in the inventories actually carried by petitioner; and the prices as of the opening and closing inventories at which, among others, petitioner was carrying these or closely comparable items.

Petitioner has refrained from restricting its search for relief to the 8 T.C. 14">*32 National Industrial Conference Board index figure or to the formula used by it in preparing its return. It states its willingness to make the adjustment by any of the possible alternative methods.

The adoption of appropriate details to accomplish the general purpose of applying the Lifo method to retail merchants could well be the subject of an administrative regulation. It might then be that any reasonable and practical method directed1947 U.S. Tax Ct. LEXIS 318">*356 by the Commissioner would be mandatory to the exclusion of others not thought by him to be adequate or authoritative.

No such regulation has been issued. But respondent takes the position for purposes of this proceeding -- not to be interpreted as generally applicable or effective beyond the confines of the present litigation -- that there is one method of computing such an index figure which he finds less objectionable than others. That is, to take the opening and closing prices, department by department, which the record shows petitioner was actually charging for such of the items as it recorded, and to give such price changes equal weights -- in other words, to compile an unweighted average -- in computing the price rise for each individual department as a whole. Since petitioner has reiterated its willingness to adopt any one of the possible alternative methods for which the figures appear, and respondent has expressed his preference for that method, we need record no opinion as to the respective virtues of the various alternative possibilities. The procedure just described should be employed for computing price changes in petitioner's store and, to afford an opportunity to1947 U.S. Tax Ct. LEXIS 318">*357 compute the final inventory figures under the Lifo method.

Decision will be entered under Rule 50.
