Per Curiam: :
This case comes before the court on defendant’s exceptions, filed April 13, 1976, to the recommended decision of Trial Judge Lloyd Fletcher, filed January 29, 1976, pursuant to Rule 134(h), having been considered on the briefs and oral argument of counsel. Since the court agrees with the trial judge’s recommended decision, as hereinafter set forth, it hereby affirms and adopts the said decision as the basis for its judgment in this case.
OPINION OP TRIAL JUDGE
Fletcher, Trial Judge:
In this case of first impression, the plaintiff, Exxon Corporation, seeks to recover an alleged overpayment of federal corporate income taxes and assessed interest thereon for the taxable year 1954.1 The tax return in question reported the operations of Humble Oil and Refining Company (Humble), a predecessor company which has been merged into Exxon, the present owner of the instant claim. The single issue is whether certain costs and expenditures incurred by Humble in the construction of offshore platforms required for the drilling of oil and gas wells in the Gulf of Mexico, are subject to the section 263 (c) option for “intangible drilling and development costs.”2 In the event the option was available to Humble, it would be permitted an election either to capitalize or to deduct as expense all “intangible drilling and development costs,” as that phrase is defined in Treasury Regulations 118 at § 39.23 (m)-16. Availability of the option depends upon classification of the expenditures as intangible drilling and development costs, as so defined, and Exxon asserts that under the precise language of the regulation, Humble’s expenditures clearly qualified for the option [261]*261to expense such, costs. The Government argues just as vigorously under the same regulation that the expenditures cannot qualify for the reasons stated by the Internal Revenue Service in its Bev. Bul. 10-596, 1970-2 C.B. 68, and therefore must be treated as capital expenditures subject only to a depreciation allowance.
For the reasons discussed below, it is my opinion that the expenditures in question do qualify under the regulations as “intangible drilling and development costs” and, hence, are subject to the option, which Humble admittedly exercised, and were properly deducted as expense items in its 1954 return.
Most of. the facts are undisputed.3 During 1954 Humble built six templet-type offshore drilling and production platforms,4 extended one of the six, and also extended one platform which had been built prior to 1954. This platform construction was done for installation on offshore leases in the Gulf of Mexico granted to Humble by the State of Louisiana which leases gave Humble an operating interest in any oil and gas discovered thereon.
The building of these platforms and platform extensions involved several stages. First, they were designed by Humble engineers who prepared detailed plans and specifications from previously furnished information as to water depths, soil, wind, tide, and storm conditions experienced at the well site, coupled with other information as to the desired size of the deck area, weight, and location of drilling equipment, and number and depth of wells to be drilled. Secondly, through competitive bidding, Humble would then engage the services of a marine construction contractor, such as W. Horace Williams Company, whose job was to fabricate on land as much of the platform as was practicable. This land-phase portion [262]*262of the work was carried out using some materials (usually the heavier steel items) supplied to the contractor by Humble.5 The remaining items of necessary materials were ordered by the contractor specifically for the Humble project. During the land phase, Humble assigned one or more of its engineers to oversee the progress of the work at the contractor’s fabrication yard and assure compliance with Humble’s specifications. In addition, a Humble welding inspector was assigned to each job for the purpose of testing the contractor’s iron workers (burners, welders, and fitters) for proficiency and inspecting the finished welds on a periodic basis.
Upon completion of the work called for by the land-phase construction contract, the partially constructed platform was loaded on a barge for transport to the drilling site. At this point, the third or so-called “water phase” of the construction began, and it was performed under a separate contract. While in transit, further welding, cutting, and fitting work was performed on the platform pieces, again under the oversight of a Humble engineer and welding inspector, who lived aboard the barge during the water-phase construction. Upon completion of this work, the platform pieces were lifted from the barge, assembled, and anchored to the sea floor by use of a large floating crane. The deck parts were then positioned and the various drilling and other equipment was installed thereon. The termination of the water phase marked the completion of the platform’s construction, whereupon it was ready for drilling operations.
Of course, during these three phases of construction, numerous costs were incurred and paid by Humble. For example, during the design phase, Humble utilized its own engineers to design the required platforms and to draft the construction plans and specifications. Other Humble personnel from the Exploration Department were used to determine the most favorable locations for well sites, and, to this end, Humble often employed outside consulting engineers to obtain and furnish information regarding soil conditions in those areas.
[263]*263During the land phase when the initial prefabrications were made, Humble incurred other costs. The land contracts awarded were typical fixed-price contracts which included the cost of labor, materials, fuel, hauling, insurance, and taxes paid by the contractor as well as the contractor’s overhead and profit. Also, during the land phase, Humble incurred the costs of transporting the materials which it had agreed to supply to the contractor’s yard as well as the costs of assigning a welding inspector and engineer to monitor the contractor’s performance. For the water phase, Humble typically awarded cost-plus-fixed-fee contracts because of the hazards and uncertainties incident to construction work at sea. The costs incurred at this stage were similar to those of the land phase covering such items as materials, wages, fuel, barge rentals, floating crane and other equipment rentals, insurance, taxes, meals and lodging during construction at the well site, as well as contractor’s profit and overhead. Of these various costs, the ones here in issue are the costs incurred for labor, fuel, repairs, supplies, and hauling during the land-phase construction of offshore platforms, together with the same categories of costs incurred during the water-phase construction of the platforms (other than the cost of transporting the platform parts to the well site which defendant concedes are allowable) prior to the time that the platform pieces and related materials were lifted by crane from the construction barge.
The defendant has conceded that 'all costs for labor, fuel, repairs, hauling, and supplies incurred by Humble for the installation of the platform after it was lifted from the barge were subject to the option and currently deductible as intangible drilling and development costs. It contends, however, that such costs incurred prior to that time are not subject to the option because they were pre-installation expenditures by which Humble acquired what the regulation calls “tangible property ordinarily considered as having a salvage value.”
It is true that Humble would dismantle platforms at locations where no economically productive wells resulted from drilling operations. The dismantling generally occurred in the reverse order of the prior erection and assembly process. [264]*264The dismantled platform parts, which were roughly the same prefabricated parts as existed at the completion of the land-phase contract, would then be taken ashore and stored. For the most part, however, Humble’s 1954 offshore platforms proved productive and have remained at the well location for production purposes. Hence, as stated above, all of the platforms and platform extensions in issue are still in place in the Gulf with the exception of platform 1428B which was dismantled during 1954 and 1955; most of its parts were reconditioned and used in the construction of another platform.6
Humble’s rejoinder to defendant’s salvage argument is simply that it raises a false and irrelevant issue. Humble points out that it always capitalized, and never expensed, the costs of the actual materials used in constructing the platforms, such as pipe, beams, and similar materials which are the only salvable items. The costs which it expensed were for items such as labor, fuel, etc., which in themselves do not have a salvage value and hence are clearly intangible drilling and development costs.
Since both parties agree that the resolution of this dispute requires an interpretation of Reg. 118, § 89.23 (m)-16, the starting point must be a quotation of the exact text of the regulation insofar as pertinent here. The pertinent parts thereof are as follows:
(a) Items chargeable to capital or to expense at taxpayer’s option:
(1) Option with respect to intangible drilling and development costs incurred by an operator (one who holds a working or operating interest in any tract or parcel of land either as a fee owner or under’ a lease or any other form of contract granting working or operating rights) in the development of oil and gas properties: All expenditures made by an operator for wages, fuel, repairs, hauling, supplies, etc., incident to and necessary [265]*265for tbe drilling of wells and the preparation of wells for the production of oil or gas, may, at the option of the operator, be deducted from gross income as an expense or charged to capital account. Such expenditures have for convenience been termed intangible drilling and development costs. They include the cost to operators of any drilling or development work (excluding amounts payable only out of production or the gross proceeds from production, and amounts properly allocable to cost of depreciable property) done for them by contractors under any form of contract, including turnkey contracts. Examples of items to which this option applies are, all amounts paid for labor, fuel, repairs, hauling, and supplies, or any of them, which are used (i) in the drilling, shooting, and cleaning of wells; (ii) in such clearing of ground, draining, road making, surveying, and geological works as are necessary in preparation for the drilling of wells; and (iii) in the construction of such derricks, tanks, pipelines, and other physical structures as are necessary for the drilling of wells and the preparation of wells for the production of oil or gas. In general, this option applies only to expenditures for those drilling and developing items which in themselves do not have a salvage value. For the purpose of this option, labor, fuel, repairs, hauling, supplies, etc., are not considered as having a salvage value, even though used in connection with the installation of physical property which has a salvage value.
* * # # ❖
(b) Recovery of optional items, if capitalized:
* * ❖ ❖ ❖
(2) Items returnable through depreciation: If the taxpayer charges such expenditures as fall within the option to capital account, the amounts so capitalized and not deducted as a loss are returnable through depreciation insofar as they are represented by physical property. Such expenditures are amounts paid for wages, fuel, repairs, hauling, supplies, etc., used in the installation of casing and equipment and in the construction on the property of derricks and other physical structures.
$ $ $ $ $
(c) Nonoptional items distinguished:
(1) Capital items: The option with respect to intangible drilling and development costs does not apply to expenditures by which the taxpayer acquires tangible property ordinarily considered as having a salvage value. [266]*266Examples of such items are the costs of the actual materials in those structures which are constructed in the wells and on the property, and the cost of drilling tools, pipe, casing, tubing, tanks, engines, boilers, machines, etc. The option does not apply to any expenditure for wages, fuel, repairs, hauling, supplies, etc., in connection with equipment, facilities, or structures, not incident to or necessary for the drilling of wells, such 'as structures for storing or treating oil or gas. These are capital items and are returnable through depreciation.
‡ $ $ $ $
“Intangible drilling and development costs” (hereinafter IDC) is a phrase peculiar to the law of oil and gas taxation and, in the words of the above regulation, is used only “for convenience.”7 It describes all expenditures made for “wages, fuel, repairs, hauling, supplies, etc., incident to and necessary for the drilling of wells and the preparation of wells for the production of oil or gas * * *” The regulation allows an “operator” the option of deducting such expenditures from gross income as expenses or charging them to capital account.
'Since the parties do not dispute that Humble was an “operator” entitled to make such election, that the offshore platforms are “physical structures,” that they are “necessary for the drilling of wells and the preparation of wells for the production of oil or gas,” and that the election was properly made, the controversy centers solely on whether the expenditures in question were for “labor, fuel, ¡repairs, hauling, and supplies * * * used * * * in the construction” of offshore platforms, within the meaning of the regulation.8
Singularly enough, both parties rely solely on the language of the regulation in formulating their positions, and the result has been aptly described by defendant as “the pervasive semantical differences which exist in this case.” Tracking the language of the regulation, plaintiff argues that all construction costs (including land costs) for items which in and of themselves have no salvage value (e.g., labor, fuel, etc.) [267]*267qualify as IDC, and emphasizes that the 'regulation specifically provides that “in general, this option applies only to expenditures for * * * items which in themselves do not have a salvage value” and that “for the purpose of this option, labor, fuel, repairs, hauling, supplies, etc., are not considered as having a salvage value, even though used in connection with the installation of physical property which has a salvage value.” It also points to the provision that “the option * * * does not apply to expenditures by which the taxpayer acquires tangible property ordinarily considered as having a salvage value * * * [such as] the actual materials in [the] structures,” and reiterates that in accordance with this latter excerpt, it has always capitalized the cost of such items as the steel pipes, beams, and other “actual materials” used in the construction of the platforms.
The defendant interprets the regulation differently but likewise directly from its wording. In the Government’s view the examples given of items within and without the option create three major categories of construction-type costs, all of which do not qualify as IDC. First, there is the category of expenditures which are “used * * * in the construction of physical structures * * * which in themselves do not have a salvage value.” These admittedly qualify as IDC. There is then a second category comprised of expenditures for labor, fuel, etc. “by which the taxpayer acquires tangible property ordinarily considered as having a salvage value.” (Emphasis added.) These acquisition expenditures, in the Government’s view, do not qualify for the option. Finally, there is a third category of expenditures for labor, fuel, etc. “used in connection with the installation of physical property which has a salvage value,” and these are qualified IDC.
It is in this last category that the Government has placed a considerable portion of the water-phase costs and allowed them to be deducted as IDC. However, the Government argues that all expenditures by Humble prior to the commencement of the water phase, and a portion thereafter, were expenditures by which Humble acquired property having a salvage value, i.e., the platform and its components. This classification of all land expenditures and a portion of the water-phase expenditures as acquisition costs is crucial to [268]*268the Government’s position that these costs must be capitalized. In my opinion, that position is untenable.
At the'outset, it may be instructive to note briefly the history of the IDC option. Although it has been available to oil and gas operators since 1917, it did not originate from any specific statutory provision but rather from Treasury Department action in the form of regulations. Despite this somewhat unusual genesis, no serious attack on the validity of the option was made. But in 1945, the Fifth Circuit Court of Appeals severely restricted the coverage of the regulation to the consternation of the oil industry. F. H. E. Oil Co. v. Commissioner, 147 F. 2d 1002, rehearing denied in 149 F. 2d 238 and again in 150 F. 2d 857 (5th Cir., 1945). This decision seemingly prompted the adoption by Congress of Concurrent Resolution 50, 79th Cong., 1st Sess., 59 Stat. 844 (1945) reading in its entirety as follows:
Resolved by the House of Representatives (the Senate concurring), That in the public interest the Congress hereby declares that by the reenactment, in the various revenue Acts beginning with the Bevenue Act of 1918, of the provisions of section 23 of the Internal Bevenue Code and of the corresponding sections of prior revenue Acts allowing a deduction for ordinary and necessary business expenses, and by the enactment of the provisions of section 711(b) (1) of the Internal Bevenue Code relating to the deduction for intangible drilling and development costs in the case of oil and gas wells, the Congress has recognized and approved the provisions of section 29.23 (m)-16 of Treasury Begulations 111 and the corresponding provisions of prior Treasury Begula-tions granting the option to deduct as expenses such intangible drilling and development costs.
Passed July 21,1945.
Congress did not thereafter revisit the IDC option until 1954 when a new Internal Bevenue Code was under consideration. At that time there was added to what became the Internal Bevenue Code of 1954 a new provision designated Section 263 (c) reading as follows:
(c) Intangible drilling and development costs in the case of oil and gas wells. — Notwithstanding subsection (a), regulations shall be prescribed by the Secretary or his delegate under this subtitle corresponding to the [269]*269regulations which, granted the option to deduct as expenses intangible drilling and development costs in the case of oil and gas wells and which were recognized and approved by the Congress in House Concurrent Resolution 50, Seventy-ninth Congress. 26 TJ.S.'C. § 263 (c) .9
From this statutory and administrative history of the IDC option, Circuit Judge (now Mr. Justice) Blackmun, speaking for a unanimous court in Harper Oil Company v. United States was able to conclude at 425 F. 2d 1335, 1342 (10th Cir.1970):
The option, although long possessed of dubious statutory ancestry, now has firm congressional authority in § 263 (c) of the 1954 Code.
This brief account of the option’s history has been stated as a prelude to the conclusion that Congress has consistently [270]*270viewed the optional treatment of IDC as an incentive to oil and gas prospecting and exploration, clearly a continuing objective of national importance.10 It follows that Congress favors a liberal, interpretation of the regulation. For example, in the House Report accompanying Concurrent Resolution 50, supra, it is stated that the “uncertainty occasioned by raising doubts as to the validity of these regulations is materially interfering with the exploration for and production of oil.” H.R. Rep. No. 761, 79th Cong., 1st Sess., p. 2 (1945). Similar concerns were expressed during floor debates on the resolution. 91 Cong. Rec. 7801-12, 8967-70 and 7891-98 (1945).11
These background observations show that the courts should not be niggardly in their approach to Reg. 118, § 39.23(m)-16. Otherwise, there is always the danger of becoming far too busy with the trees to see the forest. Equally important, however, is the realization that dealing with some of the “chameleon-hued words”12 of the regulation is a perilous venture during which care must be taken not to extend the obvious benefits of the IDC option beyond its intended boundaries, whether inadvertently or by verbal ingenuity. And, insofar as the courts are concerned, at least, no weight should be given to the revenue impact of a Congressionally-approved tax incentive such as the IDC option.13
[271]*271Keeping in mind the rather cordial attitude demonstrated by Congress towards the IDC option, I now turn to the specific words of the regulation as they apply to the costs of constructing an offshore platform. The costs generally incurred by an oil and gas operator (such as Humble) in such construction fall into several broad categories. They are the costs of the actual materials used in the structure, labor necessary to construct the same, transportation thereof, and miscellaneous costs such as repair work, fuel, supplies, and the like. Of these several categories, the regulation clearly provides that the “costs of the actual materials in those structures” may not be expensed but must be capitalized and depreciated.14 Req. § 39.23 (m)-16(c) (1). With equal clarity, however, the regulation grants an option to the operator with respect to all other of the categories listed above. The very first sentence of § 39.23(m)-16(a) (1) states:
All expenditures made by an operator for wages, fuel, repairs, hauling, supplies, etc., incident to and necessary for the drilling of wells and the preparation of wells for the production of oil or gas, may, at the option of the operator, be deducted from gross income as an expense or charged to capital account.
The regulation then goes on to place two conditions on the optional expensing of these cost items, namely, (1) they must -have been incurred “in the construction of such derricks, tanks, pipelines and other physical structures as are necessary for the drilling of wells and the preparation of wells for the production of oil or gas,” and (2) they must not in and of themselves “have a salvage value.”
The record in this case shows that, from time to time, plaintiff has recovered some materials from salvaged platforms which it reconditioned and used in other platforms. This fact is immaterial, however, because the regulation also makes it clear that of the several costs enumerated above:
* * * labor, fuel, repairs, hauling, supplies, etc., are not considered as having a salvage value, even though used in connection with the installation of physical property which has a salvage value. [Emphasis supplied.]
[272]*272Since it is agreed on both sides that the only costs in issue here are wages for labor, fuel, repairs, hauling, supplies, and the like, all of which were “incident to and necessary for the drilling- of wells” at sea, and since the listed expenditures in themselves do not have a salvage value, it would seem that the “bottom line” has been reached and the matter is at an end.
But not so, says the defendant. Pointing to the use of the word “installation” in the sentence of the regulation last quoted above, defendant concludes that the scope of the IDC option has been specifically limited so that only those expenditures incurred in the course of installing the constructed property at the well site are deductible. This interpretation excludes from the option all expenditures made in the construction of physical property at a place other than the well site no matter how necessary such pre-installation construction may have been to the drilling and preparation of the well. Such emasculation of a long-standing regulation, recognized and approved by Congress in § 263(c), supra, simply cannot be sustained.15
In seizing upon this isolated word “installation” as controlling the entire operation of the regulation, defendant has grossly misread its own language. The obvious reason for the clause in question is to eliminate a possible contention that the option-type expenditures (labor, fuel, etc.) acquire a salvage value simply because they were connected with the installation of admittedly salvable property. Thus, as plaintiff correctly observes, the clause in no way restricts the application of the regulation but instead expands it to include a situation where option-type expenditures can be related to salvable property without losing their own characterization as nonsalvable items.
In the process of advancing its impoverished interpretation, the defendant quite naturally has attempted to present it in respectable attire. Citing such authoritative decisions as Commissioner v. Idaho Power Co., 418 U.S. 1 (1974) and Southern Natural Gas Co. v. United States, 188 Ct. Cl. 302, [273]*273412 F. 2d 1222 (1969), defendant says there can be no question that labor, fuel, repairs, hauling, and supplies used in the construction of physical structures “are to be treated as part of the cost of acquisition of a capital asset.” Idaho Power Co., supra, at p. 13. Hence, they “should be included in the asset’s depreciation base, to be recovered over the life of the asset.” Southern Natural Gas Co., supra, at 188 Ct. Cl. 373, 412 F. 2d 1265.
Reliance on these cases for such a well-established rule of tax law illustrates the poverty of defendant’s argument and reveals to what extent it would mutilate the specific exception to the general rule as spelled out in Reg. 118, § 39.23 (m) - 16. Those cases involved Code § 263(a) (or a predecessor section) providing that “no deduction shall be allowed for * * * any amount paid out for new buildings * * * or betterments made to increase the value of any property * * *” In contrast, § 263(c), which adopted by reference the longstanding IDC option to deduct or capitalize such costs, is an express exception to § 263(a) and provides a choice between deduction and capitalization “notwithstanding subsection (a).” Neither section 263(c), nor the implementing regulation, was involved in the cited cases. Apparently, defendant simply refuses to recognize that the IDC deduction was intended to and does deviate significantly from the usual rules of capitalization as epitomized by § 263 (a).
Next, defendant rather surprisingly relies on the decision in Harper Oil Co., supra. The dispute there was over whether “surface casing,” which is steel pipe installed in the well to prevent water contamination and surface caving, qualified for the IDC option. The taxpayer argued that such casing did qualify because it was cemented into the ground, could not be removed under Oklahoma law, and thus had no salvage value. The Tenth Circuit disagreed and held that the cost of casing, specifically described by subsection (c) of the regulation as a nonoptional item, remained such even though under the particular circumstances the casing could not, in fact, be salvaged. Plaintiff, of course, finds no fault with this decision since it has never contended that any of its costs specifically described by the regulation as nonoptional items (such as “actual materials” or “casing”) can qualify for the [274]*274option simply because some of them may be nonsalvable. To the contrary, plaintiff instead understandably relies on the clear distinction made by the Harper Oil decision itself as follows at 425 F. 2d 1342:
* * * One might expect an expenditure for tangible hard goods, such as surface-casing, or any casing for that matter, not ordinarily to qualify as an “intangible” drilling or development cost. Standing in contrast, and qualifying, would he an appropriate labor or services cost. [Emphasis supplied.]
Defendant’s final point with respect to its salvage argument is that 'an offshore drilling platform becomes completely salvaged at the instant of an oil or gas “strike” which has the effect of converting the structure from a drilling facility to a production facility. While it is true that by the express terms of the regulation the IDC option is available only for the enumerated costs incurred during the “drilling” and “preparation” stages, it is a monstrous step to the defendant’s conclusion that “total salvage” of the entire facility occurs at the moment the oil string of casing reaches the oil trap in the producing sands. This would mean, of course, that no costs relating to a platform are deductible because they all 'have salvage value as part of a production facility. Yet, inconsistently with its argument, defendant concedes that 'hauling and installation costs are optional expenditures. Therefore, to accept such an argument would only “lead to possible inconsistencies and certainly to taxpayer and administrative confusion.” Harper Oil Co., supra, at 1343.
In addition, as plaintiff cogently points out, the argument is directly contrary to Treas. Reg. § 1.167 (a)-1(c) (and predecessor authorities) which provides that salvage occurs only “upon sale or other disposition of an asset when it is no longer useful in the taxpayer’s trade or business or in the production of his income and is to be retired from service by the taxpayer.” Clearly, plaintiff’s further utilization of platforms in the 'production of oil and gas is totally incompatible with the platforms being “retired from service” and “no longer useful in the taxpayer’s business.”
[275]*275In a supplemental brief, defendant argues that plaintiff’s reference to a provision dealing solely with depreciation is misleading. This accusation stems from defendant’s contention that the words “salvage value” when used in a provision dealing with computation of basis for depreciation mean something entirely different from those same words as they appear in the IDC regulation because there they are used in their “abstract sense.” This Alice-in-Wonderland approach cannot be accepted.16 Defendant says it is “critical to an understanding of the subject Regulation to appreciate that it applies only to qualifying expenses incurred in the drilling phase of the oil and gas business.” Df’s Supp. Br., p. 3. No one disputes the validity of this statement just as no one disputes the proposition that the actual materials used in the construction of an offshore platform have salvage value. However, it is necessary to repeat, perhaps ad nauseam, that plaintiff did not deduct the costs incurred for such items.
If, by the statement quoted above, defendant means to infer that the only deductible expenditures are those incurred during the “drilling phase” at the well site itself, then defendant is plainly wrong. In this connection, defendant has stated at pp. 22-23 of its main brief:
* * * The costs of fabricating derricks, which were purchased by the taxpayer in a prefabricated state as “a derrick”, have never been considered as being allowed by the Regulations, and the taxpayer does not suggest otherwise.
In fact, however, plaintiff does “suggest otherwise.” It vigorously, and correctly, attacks defendant’s statement as “unsupported,” and points to those provisions of the regulation which clearly state that the regulation covers optional expenses incurred by “contractors under any form of contract” and which specifically give as examples of deductible costs those “amounts paid for labor, fuel, repairs, hauling, and supplies, or any of them which are used * * * in the construction of such derricks * * * as are necessary for the drilling of wells and the preparation of wells for the production of [276]*276oil or gas.” Accordingly, plaintiff properly concludes that, when an operator who has elected the option contracts for a derrick to be built to specification, it has no choice but to deduct on a current basis those costs attributable to the contractor’s expenditures for labor, fuel, supplies, hauling and repairs. In like manner, when a platform is built under contract for an operator who has elected the option, as in this case, those same costs must be deducted currently under the regulation.
In sum, then, it must be concluded that the restrictive interpretation given to Reg. 118, § 39.23 (m)-16 by the Government as reflected in Rev. Rul. 70-596, supra,17 and elaborated upon in its briefs herein should be disapproved. By the expedient of a stingy reading, one should not frustrate the obvious Congressional purpose to encourage oil and gas prospecting, for to do so would be the most emphatic type of judicial legislation. The fragmentation of the regulation inherent in the Government’s interpretation can only result in the proliferation of ambiguities, overlaps, and problems of categorization, to say nothing of leading to that “taxpayer and administrative confusion” decried by Mr. Justice Blackmun in Harper Oil. It is far preferable and more consistent with the regulation’s purpose to interpret it as setting forth a simple and basic rule that optional intangible drilling and development costs are those expenditures 'by an oil and gas operator for items which are incident to and necessary for the drilling of wells and which, when each is considered individually as a unit in and of itself, have no salvage value.
Hence, Exxon is entitled to recover. The record indicates no dispute as to the amount of costs at issue, but to the extent disagreement should arise, determination of the exact amount of recovery will be made in further proceedings as contemplated by Kule 131 (c).
The concurring opinions of Judges Davis, Bennett and Kunzig and the concurring in part and dissenting in part opinion of Judge Kashiwa follow tlie opinion of the trial judge which has been adopted by the court.
