    UNITED STATES TAX COURT
    UNION TEXAS INTERNATIONAL CORPORATION, f.k.a.
    UNION TEXAS PETROLEUM CORPORATION, Petitioner v.
    COMMISSIONER OF INTERNAL REVENUE, Respondent
    UNION TEXAS PETROLEUM ENERGY CORPORATION
    SUCCESSOR BY MERGER TO UNION TEXAS PETROLEUM CORPORATION,
    f.k.a. UNION TEXAS PROPERTIES CORPORATION, Petitioner
    v. COMMISSIONER OF INTERNAL REVENUE, Respondent
    Docket Nos. 15182-94, 15183-94.            Filed May 21, 1998.
    R and P's predecessor, NP, executed a
    series of three Forms 872 for 1985. R did
    not know at the time of signing the Forms 872
    that NP had merged with P and that NP no
    longer had authority to extend the period of
    limitations after Dec. 31, 1991.
    Effective Dec. 31, 1982, P's
    predecessor, OP, entered into an agency
    agreement with PR, a sister company, to
    process and sell propane for OP and NP to
    unrelated third parties. OP and NP retained
    title to its propane until PR sold it to
    unrelated third parties. PR also sold its
    own propane to T, a related retailer.

    Ps assert that they should be permitted
    to use differing allocations for computing
    the Windfall Profit Tax (WPT) and Percentage
    Depletion Net Income Limitation (NIL).
    1. Held: P, Energy, is estopped to deny the
    validity of the Forms 872. Knowledge of the
    merger is not attributed to R's WPT agents;
    computerized information of the merger was
    not accessible to them.
    2. Held: Ps are independent producers,
    because they did not sell their propane to T.
    3. Held: Sec. 4988(b)(3)(A), I.R.C., requires
    Ps to compute the NIL in the same manner
    under sec. 4988(b)(3)(A), I.R.C. and sec.
    613, I.R.C.
    Jasper George Taylor III, Charles Washington Hall,
    William H. Caudill, and John B. Kinchen, for petitioners.
    Sheri Wilcox, for respondent.
    OPINION
    PARR, Judge:   In these consolidated cases, respondent
    determined the following deficiencies in windfall profit tax
    (WPT) for the taxable periods of 1983, 1984, and 1985,
    respectively: $3,471,045, $3,060,042, and $2,109,854.    Respondent
    determined the deficiencies against Union Texas Petroleum
    International (International) for 1983 and 1984, and against
    Union Texas Petroleum Energy (Energy) for 1985.   In their
    petitions, petitioners raised an issue pursuant to section
    - 3 -
    6512(b)1, claiming overpayments of WPT for the taxable periods of
    1983, 1984, and 1985, respectively, in the following amounts:
    $6,107,901, $5,969,611, and $7,931,434, resulting from a
    recomputation of the WPT net income limitation (NIL), or WPT NIL.
    After concessions by the parties2, the issues for decision
    are:    (1) Whether petitioner, Energy, should be equitably
    estopped to deny that the limitations period for the taxable
    periods of 1985 were extended properly under section 6501(c)(4).
    We hold it should.    (2) Whether, pursuant to section 613A(d)(2),
    Union Texas Petroleum Corporation (Old Petroleum) and Union Texas
    Petroleum Corporation (New Petroleum), f.k.a. Union Texas
    Properties Corporation (Properties) were independent producers
    during the taxable years in issue.      We hold they were.
    (3) Whether petitioners are entitled to recompute Old Petroleum's
    and New Petroleum's WPT NIL computations for the taxable periods
    of 1983, 1984, and 1985, where the recomputations do not follow
    1
    All section references are to the Internal Revenue Code in
    effect for the years in issue, and all Rule references are to the
    Tax Court Rules of Practice and Procedure, unless otherwise
    indicated.
    2
    Subject to the issues discussed herein, including the
    overpayment issue, petitioners conceded the remaining issues
    raised in the notices of deficiency and petitions. Respondent
    conceded that petitioners are entitled to exclude from gross
    income a ratable portion of the lease bonus payments made with
    respect to producing properties for purposes of computing the WPT
    NIL and that petitioners are entitled to capitalize lease bonus
    payments in determining "as if" cost depletion.
    - 4 -
    the percentage depletion calculations claimed on their original
    Federal income tax returns.   We hold they are not.3
    Some of the facts have been stipulated and are so found.
    The stipulated facts and the accompanying exhibits are
    incorporated into our findings by this reference.      At the time
    the petitions in these cases were filed, petitioners' principal
    place of business was located in Houston, Texas.    For
    convenience, we present a general background section and combine
    our findings of fact with our opinion under each separate issue.
    General Background
    Corporate Structure--1982 Reorganization
    Until December 31, 1982, Old Petroleum (Employer
    Identification Number, hereinafter EIN XX-XXXXXXX), a Delaware
    corporation, was a subsidiary of Allied Corporation (Allied), a
    New York corporation.   Old Petroleum owned and operated 10
    natural gas processing plants and held nonoperating interests in
    additional gas processing plants.   During that time, Old
    Petroleum owned 100 percent of the stock of Texgas Corporation
    (Texgas), a Delaware corporation, which was in the business of
    retailing propane.
    In a December 31, 1982, reorganization, Allied formed a new
    corporation called Union Texas Petroleum Holdings, Inc.
    (Holdings) (EIN XX-XXXXXXX) to serve as the parent of Old
    3
    We have considered each of the remaining arguments of the
    parties and, to the extent that they are not discussed herein,
    find them to be unconvincing.
    - 5 -
    Petroleum and a new corporation called Union Texas Products
    Corporation (Products), a Delaware corporation.4    Pursuant to the
    reorganization, Old Petroleum contributed all of the assets of
    its hydrocarbons division to Products, including its natural gas
    gathering lines, gas processing plants, storage facilities,
    contracts for the sale of petroleum products, and all of the
    stock of Texgas.   In exchange, Old Petroleum received the stock
    of Products, which it then distributed to Holdings.    Thereafter,
    Products was a direct subsidiary of Holdings, Texgas was a direct
    subsidiary of Products, and Old Petroleum did not own stock in
    Products or Texgas.
    Corporate Structure--1984 Reorganization
    In a December 31, 1984, reorganization, Old Petroleum
    transferred all of its domestic oil and gas properties to New
    Petroleum (EIN XX-XXXXXXX), a Delaware corporation and subsidiary
    of Holdings, then known as Properties.   On March 5, 1985, New
    Petroleum changed its name from Union Texas Properties
    Corporation to Union Texas Petroleum Corporation.    Old Petroleum,
    presently known as International, currently exists as a Delaware
    corporation and is the petitioner in the instant case with
    respect to 1983 and 1984.
    Corporate Structure--1991 Reorganization
    On October 15, 1991, Holdings became the parent of a new
    corporation called Union Texas Petroleum Energy Corporation, or
    4
    Effective July 2, 1985, Allied sold one-half of the stock of
    Holdings.
    - 6 -
    Energy (EIN XX-XXXXXXX), a Delaware corporation.    Effective
    December 31, 1991, pursuant to Delaware Corporation Law, New
    Petroleum merged into Energy and ceased to exist.    Energy was the
    surviving corporation under Delaware law and is the petitioner in
    the instant case with respect to 1985.5
    Issue 1. Equitable Estoppel for the Taxable Periods of 1985
    1985 Forms 872--Consent To Extend the Time To Assess Tax
    In the 1984 reorganization, Old Petroleum transferred its
    domestic oil and gas properties to New Petroleum, then known as
    Properties.   Thus, the responsibility for filing WPT returns
    shifted from Old Petroleum to Properties.   On March 5, 1985,
    Properties changed its name to New Petroleum.   Despite the name
    change, New Petroleum continued to file its Forms 720, Quarterly
    Federal Excise Tax Returns (Forms 720), for the first three
    taxable quarters of 1985 under the name of Properties.
    To keep the period of limitations open while respondent
    continued to conduct the WPT examination of New Petroleum for the
    1985 taxable periods, respondent and New Petroleum began
    executing a series of Forms 872, the last of which was meant to
    extend the limitations period to June 30, 1994.    At that time,
    what respondent's WPT revenue agents (WPT agents or agents) did

    When this opinion addresses the actions of the actual
    parties to this litigation, the term "petitioners" refers to
    Energy and International.
    When references in this opinion apply to all of the
    affiliated Union Texas Petroleum corporate entities, either the
    term Union Texas companies or affiliated corporations is used.
    - 7 -
    not know was that there had been another reorganization in which
    New Petroleum merged with Energy, and as of December 31, 1991,
    ceased to exist.   As a result of the merger, New Petroleum no
    longer had authority to extend the period of limitations after
    December 31, 1991.   Yet, New Petroleum, through its former
    officers, Sanford M. Lobliner (Lobliner), and M.N. Markowitz
    (Markowitz),6 executed the following three Forms 872 after it had
    merged out of existence:
    Extended Date   Date New Petroleum Signed   Date Respondent Signed
    6/30/93            7/22/92                       8/24/92
    12/31/93            1/14/93                       2/11/93
    6/30/94            7/27/93                       7/30/93
    Each of these three consents was prepared by respondent's
    Appeals Office in Houston, Texas.   Each consent identified the
    taxpayer as "Union Texas Petroleum Corporation (formerly Union
    Texas Properties Corporation) (Successor to Union Texas Petroleum
    Corporation XX-XXXXXXX)" and listed the EIN as XX-XXXXXXX.    The
    consents should have identified the taxpayer for 1983 and 1984 as
    Union Texas International Corporation, F.K.A. Union Texas
    Petroleum Corporation, and for 1985 as Union Texas Petroleum
    Energy Corporation, successor by merger to Union Texas Petroleum
    Corporation, F.K.A. Union Texas Properties Corporation.   When New
    Petroleum returned the consents to respondent, the Form 872
    extending the assessment date to June 30, 1993, bore Lobliner's
    signature, and the two Forms 872 extending the assessment dates
    6
    In 1992 and 1993, respectively, Lobliner and Markowitz were
    the vice presidents of Energy and would have had authority to
    have properly prepared a Form 872 on petitioners' behalf.
    - 8 -
    to December 31, 1993, and June 30, 1994, respectively, bore
    Markowitz's signature, both of whom signed as vice presidents of
    New Petroleum.
    On March 9, 1992, respondent sent New Petroleum the revenue
    agent's report for the taxable periods of 1985, addressed to
    Union Texas Petroleum Corporation, F.K.A. Union Texas Properties
    Corporation, as was the consent.   On April 24, 1992, in response
    to the revenue agent's report, Lobliner submitted to respondent a
    protest of respondent's determinations for 1985.   The protest was
    on a preprinted letterhead styled Union Texas Petroleum.   The
    case remained under consideration by respondent's Appeals Office
    until May 26, 1994, when the notice of deficiency for 1985 was
    issued.7
    At no time before the petitions in these cases were filed
    did anyone representing New Petroleum or Energy directly inform
    the agents conducting the WPT examination or the Appeals officers
    considering the cases that New Petroleum was defunct and had no
    authority to act, that Lobliner and Markowitz were not officers
    of New Petroleum and did not have authority to execute the Forms
    872 for the 1985 taxable periods, that future correspondence
    7
    On May 26, 1994, respondent mailed two notices of deficiency
    to petitioners' Houston address. The notice of deficiency for
    1983 and 1984 was in the name of Old Petroleum with EIN 74-
    6044301. Those years are not affected by the equitable estoppel
    issue. The notice of deficiency for 1985 was in the name of New
    Petroleum with EIN XX-XXXXXXX. This is the deficiency notice
    subject to the equitable estoppel issue.
    - 9 -
    should be directed to Energy, or that future Forms 872 should be
    executed by Energy.
    Discussion
    Respondent contends that Energy should be estopped to deny
    the validity of the last three Forms 872 signed by Lobliner and
    Markowitz on behalf of New Petroleum, because Energy, through its
    officers, agents or employees, intentionally deceived respondent
    by failing to disclose New Petroleum's merger into Energy,
    thereby causing respondent to withhold assessment in reliance
    upon the consents.    Energy asserts that it did not make any false
    representations to, or maintain any misleading silences in
    connection with, New Petroleum's merger into Energy.
    Furthermore, Energy claims that when the last three Forms 872
    were signed respondent not only knew of New Petroleum's merger,
    but had a convenient means of acquiring such knowledge.    Finally,
    Energy contends that in preparing and executing the last three
    Forms 872, respondent did not rely on any acts or statements made
    by Energy's representatives, because respondent's agents prepared
    the Forms 872 by looking only at prior Forms 872 and New
    Petroleum's Federal income tax return for the year in issue.
    Pursuant to section 6501(c)(4) a taxpayer and the Secretary
    or his delegate, before the expiration of the period provided by
    statute for assessment and collection of income tax, may consent
    in writing to an extension of that period, and further extensions
    may be made by subsequent written agreements entered into before
    the expiration of the period previously agreed upon.
    - 10 -
    Respondent concedes that because the Forms 872 were signed
    by Lobliner and Markowitz on behalf of New Petroleum after it had
    merged out of existence, and not on behalf of Energy, they were
    invalid.   Thus, respondent further concedes that since the notice
    of deficiency for Energy's 1985 taxable periods was mailed more
    than 3 years after Energy filed its Federal income tax return for
    that year, assessment and collection of a deficiency for 1985 are
    barred, unless we hold that the last three Forms 872 signed by
    Lobliner and Markowitz are valid extensions of the statute of
    limitations.   Sec. 6501(a).
    Generally speaking, equitable estoppel precludes a party
    from denying that party's own acts or representations which
    induced another to act to the other's detriment.    Graff v.
    Commissioner, 
    74 T.C. 743
    , 761 (1980), affd. per curiam 
    673 F.2d 784
     (5th Cir. 1982).   The doctrine of equitable estoppel is based
    on the grounds of public policy, fair dealing, good faith, and
    justice, and is designed to aid the law in the administration of
    justice where without its aid injustice might result. 
    Id.
          The
    elements of equitable estoppel have been variously described, but
    for our purposes they may be stated as follows:    (1) There must
    be a false representation or wrongful misleading silence by the
    party against whom the estoppel is claimed; (2) the error must
    originate in a statement of fact, not in opinion or a statement
    of law; (3) the party claiming the benefits of the estoppel must
    have actually and reasonably relied on the acts or statement of
    - 11 -
    the party against whom the estoppel is claimed, and as a
    consequence of that reliance must be adversely affected by the
    acts or statements of the one against whom an estoppel is
    claimed; and (4) the party claiming the benefits of estoppel must
    not know the true facts.    Century Data Sys., Inc. v.
    Commissioner, 
    86 T.C. 157
    , 165 (1986); Graff v. Commissioner,
    supra at 761; Steiner v. Commissioner, 
    T.C. Memo. 1995-122
    .       The
    party affirmatively asserting an estoppel has the burden of
    proving all the essential elements constituting the estoppel.
    Steiner v. Commissioner, supra.    Accordingly, respondent bears
    the burden of proving each of the above elements.    Rules 39,
    142(a).
    1. Misrepresentation or Misleading Silence
    To sustain equitable estoppel, respondent must show that
    Energy took "some action" which misled respondent.       Century Data
    Sys. Inc. v. Commissioner, supra at 166.    Respondent contends
    that Energy made false representations or wrongful misleading
    silences, when it did not tell respondent that New Petroleum had
    merged out of existence, and that its officers had no power to
    act.    Respondent further contends that the representations were
    part of a pattern of false representations and misleading
    silences that caused respondent to believe mistakenly that the
    period of limitations had been extended.    Respondent argues that
    these material misrepresentations were bolstered by Energy's
    continuing relations with respondent's Appeals officers, where 25
    - 12 -
    items of correspondence were sent and received during the audit
    process in the name of Union Texas Petroleum Corporation, without
    any mention of a change in corporate structure.      Respondent
    further argues that Energy was aware of respondent's concern with
    the accuracy of the name and signature on the Forms 872.      In
    fact, once respondent learned that Properties had changed its
    name to New Petroleum, respondent immediately sought new Forms
    872, reflecting the new name.      Moreover, respondent notes that
    during the examination of the taxable periods of 1983 and 1984,
    Union Texas Petroleum's Chief Executive Officer gave respondent a
    letter certifying Lobliner's authority to execute consents for
    those years.    Respondent contends that Energy's failure to inform
    respondent that Lobliner, and subsequently Markowitz, no longer
    had authority to act on behalf of New Petroleum was clearly
    disingenuous.
    We agree with respondent.   We are not persuaded by
    petitioner's attempt to obfuscate this issue with the testimony
    of Joseph Wayne Cliett (Cliett), who was the supervisor of tax
    audits for Old Petroleum, New Petroleum, Energy, and the other
    affiliated corporations at the time of trial and during the
    taxable years in issue.    Cliett, as tax supervisor of the Union
    Texas companies, knew of the tax returns being filed by each of
    the different Union Texas companies.      Moreover, he was
    responsible for obtaining the appropriate signatures on the Forms
    872.    Cliett testified that upon receiving the first of the last
    - 13 -
    three Forms 872 from the Internal Revenue Service (IRS) which
    extended the assessment date to June 30, 1993, Cliett presented
    it for signature to Lobliner, his supervisor during 1992.     Upon
    receiving the last two Forms 872 which extended the assessment
    date to December 31, 1993, and June 30, 1994, respectively,
    Cliett presented them for signature to Markowitz, who became his
    supervisor sometime in 1993.   Cliett alleges, however, that when
    he presented the last three Forms 872 for signature to Lobliner
    and Markowitz he did not know that New Petroleum had dissolved.
    Cliett claims that he was not aware of the merger, because his
    payroll checks failed to identify the specific entity for which
    he worked, and he did not pay "much attention" to the Forms W-2
    that he received.
    We find Cliett's testimony to be implausible given his
    extensive tax and accounting background, coupled with his vast
    knowledge of petitioners' business organization and operations.
    Cliett testified that he has worked nearly 30 years for
    petitioners or one of their affiliated corporations, that he is
    the supervisor for tax audits, and he is familiar with the
    business organization and operations of the Union Texas
    companies.   At trial, Cliett was easily able to identify each
    Union Texas company, to delineate the various departments within
    each corporation, and to describe the primary functions of each
    division within the various corporate departments.   Thus, it is
    most difficult to believe that at the time the last three Forms
    - 14 -
    872 were signed, Cliett did not know of New Petroleum's
    dissolution or did not know that Lobliner and Markowitz no longer
    had authority to sign the Forms 872 on behalf of the defunct
    corporation.
    Assuming arguendo, that Energy knew of the error contained
    in the last three Forms 872 (which it does not concede), Energy,
    in reliance on Century Data Sys., Inc. v. Commissioner, supra at
    170, asserts that it was under no affirmative duty to bring
    respondent's mistakes to respondent's attention.    We disagree and
    find Energy's reliance on Century Data Sys., Inc. v. Commissioner
    to be misplaced.   Energy fails to mention this Court's
    qualification of that proposition; namely, that there is no
    obligation to correct respondent's mistakes provided the
    "petitioner did nothing to encourage the faulty assumption." Id.
    at 171.   Here, Energy's entire course of conduct encouraged
    respondent's faulty belief that New Petroleum existed at the time
    the last three Forms 872 were signed.    When Lobliner and
    Markowitz signed the last three consents Energy knew that New
    Petroleum did not exist, and that Lobliner and Markowitz were not
    officers of that corporation.    Energy not only failed to call
    this error to respondent's attention, but intentionally fostered
    it by continuing to communicate to the IRS through correspondence
    that bore the name and EIN of the dissolved corporation.     Thus,
    based on the record and the facts discussed herein, we find that
    - 15 -
    respondent has met his burden of proving that these actions
    satisfy the first element of equitable estoppel.
    2. Fact or Law
    For equitable estoppel to apply, the misrepresentation or
    wrongful misleading silence generally must originate in a
    statement of fact and not in an opinion or a statement of law.
    Graff v. Commissioner, 
    74 T.C. at 761
    .
    While it could be argued that the effect of New Petroleum's
    merger into Energy is a legal question, the misrepresentations or
    silence relate to the facts herein; namely, that at the time the
    last three Forms 872 were signed New Petroleum existed, and that
    the individuals signing the consents were its properly authorized
    officers.   Given that Energy's misrepresentations or wrongful
    misleading silences clearly originate in a statement of fact, we
    find respondent has met his burden with respect to the second
    element of equitable estoppel.
    3. Detrimental Reliance
    "It is fundamental to the doctrine of estoppel that the
    party raising the issue must have been misled in reliance upon
    the representations of his opponent." Century Data Sys., Inc. v.
    Commissioner, 
    86 T.C. at 166
    ; see also Atlas Oil & Ref. Corp. v.
    Commissioner, 
    22 T.C. 552
    , 559 (1954) (taxpayer must be shown to
    have taken some action which led Commissioner to postpone until
    after the period of limitations expired the issuance of a notice
    of deficiency that he was otherwise prepared to mail on a timely
    basis).
    - 16 -
    Here, Energy's critical act was to sign the consents without
    informing respondent that the individuals signing them were not,
    as they represented themselves to be, officers of New Petroleum.
    Had respondent known that Lobliner and Markowitz were not
    officers of New Petroleum and that the corporation did not exist,
    respondent could have obtained either a correct consent from
    Energy or issued a notice of deficiency before the period of
    limitations expired with respect to 1985.   Accordingly, we find
    that respondent reasonably relied to his detriment on
    petitioner's misrepresentations or silences with respect to the
    merger transaction.
    4. Knowledge of the Facts
    To meet the fourth prong of equitable estoppel, the
    Government must prove not only that respondent was "'destitute of
    knowledge of the real facts as to the matter in controversy, but
    should also have been without convenient or ready means of
    acquiring such knowledge.'"   Southwestern Inv. Co. v.
    Commissioner, 
    19 B.T.A. 30
    , 47 (1930) (citing Brant v. Virginia
    Coal and Iron Company, et. al, 
    93 U.S. 326
    , 337 (1876)).
    Respondent contends that neither the agents nor Appeals
    officers involved with the WPT audit had actual knowledge of New
    Petroleum's dissolution at the time the last three Forms 872 were
    signed.   Moreover, respondent points to the fact that petitioners
    stipulated that both Energy and New Petroleum failed to inform
    the WPT agents of the true situation regarding the merger.
    - 17 -
    Energy asserts that even if the WPT agents did not have
    actual knowledge of the merger (a fact which it does not
    concede), numerous documents submitted to respondent's service
    center constituted sufficient notice to respondent that New
    Petroleum had ceased to exist at the time New Petroleum signed
    the last three Forms 872, on July 22, 1992, January 14, 1993, and
    July 27, 1993, respectively.   It is stipulated that no later than
    May 11, 1992, more than 3 months before the first Form 872 was
    signed, the Austin Service Center received New Petroleum's final
    quarterly employment tax return (Form 941) marked "cancel
    corporation merged out of existence."   Energy further points out
    that respondent stipulated that no later than September 8, 1992,
    respondent's Austin Service Center received copies of a statement
    of merger as required under section 1.368-3, Income Tax Regs.,
    and a certificate of merger of New Petroleum into Energy,
    respectively, that were attached to the 1991 consolidated Federal
    income tax return (Form 1120), filed by Holdings, New Petroleum's
    parent company.   Finally, in reliance on Badger Materials, Inc.
    v. Commissioner, 
    40 T.C. 725
    , 733, withdrawn and modified in part
    by Badger Materials, Inc. v. Commissioner, 
    40 T.C. 1061
     (1963)
    (not affecting this issue), Energy contends that as of December
    17, 1991, when the certificate of merger was filed with the
    Delaware secretary of state indicating that as of December 31,
    1991, New Petroleum would cease to exist, such information became
    a matter of public record and readily available to respondent.
    Accordingly, petitioner contends that respondent not only had
    - 18 -
    actual knowledge of the merger, but also had the means by which
    respondent's WPT agents could have readily acquired such
    knowledge.   Southwestern Inv. Co. v. Commissioner, supra.
    In Paramount Warrior, Inc. v. Commissioner, T.C. Memo. 1976-
    400, affd. without published opinion 
    608 F.2d 522
     (5th Cir.
    1979), a case which is in many respects similar to the instant
    case, we declined to decide whether the notification of a merger
    in correspondence with one of respondent's service centers, or in
    a parent company's consolidated return, constituted sufficient
    knowledge on the part of respondent, because we found as a fact
    that the field agents involved with the examination had actual
    knowledge that the corporation, on whose behalf the Forms 872
    were signed, had merged out of existence. 
    Id.
       In the instant
    case, we are faced with precisely the question deferred in
    Paramount Warrior.
    Energy asserts that the two groups of documents filed with
    respondent's Austin Service Center should be considered notice of
    New Petroleum's dissolution, and therefore such knowledge should
    be attributable to the WPT agents who conducted the examination
    and who drafted the last three Forms 872.   The first group of
    documents on which Energy relies consists of the 1991
    consolidated Form 1120 filed by Holdings along with the merger
    documents attached thereto.   The second group of documents
    consists of the 1991 employment tax returns (Forms 940 and 941)
    filed in New Petroleum's name. Energy argues that the WPT agents
    - 19 -
    should be charged with knowledge of the information contained in
    these documents.
    Respondent contends that the revenue agents and Appeals
    officers involved in the WPT cases could not have been expected
    to learn of New Petroleum's merger from the information submitted
    to the Austin Service Center in Holding's 1991 Form 1120.    For
    income tax purposes, New Petroleum was a member of a consolidated
    group headed by Holdings.   Accordingly, the statement of merger
    and certificate of merger which New Petroleum filed were attached
    to Holdings' Form 1120 as pages 573 and 574, respectively, of a
    632-page consolidated Federal income tax return.    The income tax
    return was filed under the name and EIN of Holdings, which was
    different from Energy's EIN.     Moreover, neither page 573 nor page
    574 contained Energy's EIN.    Thus, respondent contends that the
    computer transcripts requested by the WPT agents using New
    Petroleum's EIN did not reflect the changes in its corporate
    status shown on Holdings' Form 1120.
    We agree with respondent.    It is stipulated that the Austin
    Service Center received Holdings' Form 1120 on September 8, 1992,
    after the first of the three Forms 872 was signed.    However, an
    inspection of the actual Form 1120 reveals that the return was
    not surveyed by the income tax examination group until January
    14, 1995, nearly 18 months after the last consent in issue was
    signed.   Thus, based on the facts discussed herein, we shall not
    attribute knowledge of New Petroleum's merger, which may have
    been acquired by revenue agents conducting an unrelated income
    - 20 -
    tax audit of petitioners for the taxable years in issue, nearly
    18 months after the last consent was signed, to the agents or
    Appeals officers conducting the WPT examination.     Cf. King v.
    Commissioner, 
    857 F.2d 676
    , 680 (9th Cir. 1988) (adopting general
    theory that knowledge acquired by the IRS in unrelated
    investigations is not necessarily imputed from one division to
    another and citing United States v. Zolla, 
    724 F.2d 808
    , 810-811
    (9th Cir. 1984)), affg. 
    88 T.C. 1042
     (1987).   Furthermore, we
    find that New Petroleum did not provide respondent with notice of
    the merger by filing Forms 940 and 941 in 1991 (employment tax
    filings), because, as in the income tax situation, those filings
    address a different tax, a different form, and are subject to
    review by a different IRS division. 
    Id.
    With respect to the information available to the WPT agents
    in the IRS' computer system, the record establishes that although
    a computer updating procedure existed for income tax return
    audits which would have reflected a change in New Petroleum's
    corporate status, there was no such system in place for audits of
    WPT or employment tax returns.   At trial, Revenue
    Agent Bruce Rhames (Agent Rhames), the group manager assigned to
    conduct the WPT examination for 1985, credibly testified that
    where, as in the instant cases, the income tax returns were not
    under his control and something changed which did not pertain
    exactly to his taxpayer, such as a change in the taxpayer's name,
    its EIN, or the amount of tax paid, he was not notified of the
    change.   Rhames explained that New Petroleum's merger into Energy
    - 21 -
    was not reflected in the computer transcripts generated using New
    Petroleum's EIN, which were used to confirm that the information
    on the last three Forms 872 was correct.
    Respondent's argument rests on the premise that any
    knowledge of New Petroleum's merger obtained by personnel at the
    Austin Service Center should not be attributed to the WPT agents,
    because respondent did not have a computer system in place at the
    time the last three Forms 872 were drafted, which would have
    enabled the agents to access this information easily.   We agree
    with respondent.   See also Southwestern Inv. Co. v. Commissioner,
    
    19 B.T.A. 30
     (1930) (citing Brant v. Virginia Coal & Iron Co., 
    93 U.S. 326
    , 337 (1876); cf. Abeles v. Commissioner, 
    91 T.C. 1019
    (1988).
    In Abeles v. Commissioner, supra at 1035, our decision
    turned on the then-existing availability of computer-generated
    information using the taxpayer's Social Security number.     There,
    we held that for purposes of determining whether a notice of
    deficiency has been properly mailed to the taxpayer's last known
    address, an agent issuing a deficiency notice generally is
    charged with knowledge of a taxpayer's last known address which
    appears on the taxpayer's most recently filed tax return.    In
    Abeles, we found as a fact that the then-existing computer
    capabilities of the IRS were such that an agent responsible for
    issuing a notice of deficiency had the ability to conduct, within
    a few moments, a search of the IRS computer files for a more
    recent address for the taxpayer. Id. at 1033-1035.   In so
    - 22 -
    holding, we noted that "the state of the IRS' computer
    capabilities is such that a computer search of the information
    retained with respect to a certain taxpayer, including their last
    known address, may be performed by respondent's agent without
    unreasonable effort or delay." Id. at 1033.
    Here, the IRS' computer system did not provide the ability
    to conduct within a reasonable time a cross-check of the
    taxpayer's income tax, WPT, and employment tax returns that would
    have revealed the taxpayer's change in corporate status, using a
    single EIN.   Thus, Abeles v. Commissioner, supra, while
    analogous, is clearly distinguishable from the case at hand.
    Finally, we address Energy's argument that respondent easily
    could have determined that New Petroleum had merged out of
    existence by checking with the Delaware secretary of state, which
    as of December 17, 1991, had the certificate of merger on file.
    In making this argument, Energy relies on Badger Materials, Inc.
    v. Commissioner, 
    40 T.C. 725
    , 733 (1963), withdrawn and modified
    in part by Badger Materials, Inc. v. Commissioner, 
    40 T.C. 1061
    (1963) for the proposition that filing of merger documents with
    the secretary of state constitutes notice of merger to the IRS.
    We disagree and find Energy's reliance on Badger Materials, Inc.
    to be misplaced.   In Badger Materials, Inc., the taxpayer
    corporation was dissolved and generally ceased to exist.
    Following the dissolution, the treasurer of the defunct
    corporation executed consents purporting to extend the period for
    assessment of Federal income tax.   Within the period of
    - 23 -
    limitations as purportedly extended, the IRS issued a notice of
    deficiency to the corporation and a notice of transferee
    liability to the transferee of the corporation's assets.      The
    corporation and the transferee denied the validity of the
    consents on the ground that they were executed after the
    corporation had been dissolved.    The IRS argued that the
    corporation and transferee were equitably estopped from denying
    the validity of the consent forms.       We disagreed and held for the
    taxpayers.
    However, the facts in Badger Materials, are distinguishable
    from the facts herein.   In Badger Materials, we found as fact
    that there was no lack of knowledge of the corporation's
    dissolution on the part of the IRS.      Energy argues that Badger
    Materials stands for the proposition that the Government had
    knowledge of the corporation's merger at the time the consent
    forms were signed, because the corporation had filed articles of
    dissolution with the secretary of state of Wisconsin, thus making
    the matter "public record".   However, the filing of dissolution
    documents was merely one fact that this Court relied on in
    holding for the taxpayers.    There, the taxpayer corporation also
    filed a final Federal income tax return with the IRS under its
    own name and listing its EIN.    The return included a statement
    concerning the liquidation and a copy of the minutes of the
    stockholder's meeting adopting the plan of dissolution.      Here, as
    previously discussed, the statement of merger and the certificate
    of merger filed by New Petroleum were attached as pages 573 and
    - 24 -
    574 of a 632-page consolidated Federal income tax return filed by
    Holdings, New Petroleum's parent corporation.    Moreover, in
    Badger Materials, we attributed the merger information contained
    in the taxpayer's Federal income tax return to the agent
    conducting the income tax audit, not to an agent responsible for
    an unrelated audit of a different kind of tax.
    Finally, although neither party addresses this point, we
    note that the returns under audit herein for the taxable periods
    of 1985 were New Petroleum's Quarterly Federal Excise Tax Returns
    (Form 720).   On Form 720, there is a line which states that if
    the taxpayer will not be liable for returns in succeeding
    quarters, then the word "FINAL" should be entered.    Had New
    Petroleum entered the word "FINAL" on the appropriate line, that
    might have been sufficient to put respondent on notice of New
    Petroleum's merger into Energy.   However, Energy's failure to
    introduce into evidence New Petroleum's final 1991 Form 720 leads
    us to infer that no such entry appears on the form.    See Wichita
    Terminal Elevator Co. v. Commissioner, 
    6 T.C. 1158
    , 1165 (1946),
    affd. 
    162 F.2d 513
     (10th Cir. 1947).
    Thus, based on the record and the facts discussed herein, we
    hold that Energy is equitably estopped to deny that the
    limitations period for the taxable periods of 1985 was extended
    properly under section 6501(c)(4).8
    8
    Even if we were to find that the error in the extension was
    the result of mutual mistake, rather than any deliberate
    deception on petitioner's part, the Court has the power to reform
    (continued...)

    Issue 2.    Independent Producer Issue9
    Background
    Pursuant to the 1982 reorganization, Old Petroleum
    contributed all of the assets of its hydrocarbons division to
    Products, including all of the stock of Texgas.     In exchange, Old
    Petroleum received the stock of Products, which it then
    distributed to Holdings, the parent company of Products and Old
    Petroleum.    Thereafter, Products owned 100 percent of the stock
    of Texgas, a retailer of propane,10 and Old Petroleum no longer
    owned stock in Products or Texgas.      In the December 31, 1984,
    reorganization, Old Petroleum transferred all of its domestic oil
    and gas properties to New Petroleum, which was also a subsidiary
    of Holdings.    Petroleum, Products, and Texgas were related
    persons within the meaning of section 613A(d)(3).
    Petroleum was in the oil and gas exploration and production
    business.    Products was in the business of processing and
    marketing oil and natural gas and their derivatives, including
    propane, for Petroleum as well as for unrelated oil and gas
    producers.

    the parties. See Woods v. Commissioner, 
    92 T.C. 776
    , 789 (1989).
    9
    When references in this opinion apply to both Old Petroleum
    and New Petroleum, the term "Petroleum" is used.
    10
    Propane is a product derived from natural gas under sec.
    1.613A-7(r)(3), Income Tax Regs. Accordingly, references herein
    to natural gas include propane.
    - 26 -
    Effective December 31, 1982, Old Petroleum and Products
    entered into a service agreement under which Products agreed, for
    a cash fee, to act as an agent for Petroleum to process and sell
    its propane to unrelated third parties.    As Petroleum's agent,
    Products handled Petroleum's marketing, distribution, storage,
    sales, and collection efforts.   Pursuant to the service
    agreement, Petroleum retained title to its propane until Products
    sold the propane on Petroleum's behalf to unrelated third
    parties.   Neither Products nor Texgas was a buyer or seller under
    Petroleum's sales contracts with unrelated third parties.
    Petroleum produced natural gas from individual wells, which
    went to 10 different processing plants.    From 3 of the 10
    processing plants, Petroleum moved its propane by pipeline to a
    storage terminal at Mont Belvieu, Texas.    By exchange agreements,
    Petroleum exchanged the volumes of propane at the 7 other plants
    for a like volume of propane held by Products.    Petroleum's use
    of the exchange agreements as a substitute for physical
    transportation was both economically efficient and a common
    practice in the oil and gas industry.   Moreover, the propane
    owned by Petroleum and Products satisfied strict industry
    standards so that the propane volumes could be easily commingled
    and exchanged.
    As Products sold Petroleum's propane, the accounting group
    recorded those sales as Petroleum's sales in accordance with
    Petroleum's accounting practices, which were customary in the oil
    and gas business and were consistently applied.    Petroleum's
    - 27 -
    general ledger showed the sale of Petroleum's propane inventory
    by Petroleum, with Products as agent, to unrelated third parties
    in bulk sales.     Petroleum's handling of its propane inventory was
    consistent with industry practice.
    As agent for Petroleum, Products collected from third party
    purchasers payments due to Petroleum, and it was responsible for
    pursuing any unpaid propane bills.           If, however, a bill remained
    unpaid, it was Petroleum, not Products, that had to bear the
    loss. For the taxable years in issue, Petroleum, Products, and
    Texgas had the following volumes and values of propane
    production:

    Petitioners concede that due to an accounting error, the $2,307,907
    amount shown as Old Petroleum's propane sales for 1984, although reflected in
    Petroleum's books, does not include gross receipts received by Old Petroleum
    from its sales of 818,708 gallons of propane in December 1984. The highest
    price per gallon of propane during 1984 was approximately 58 cents. Thus, Old
    Petroleum's gross receipts from its December 1984 propane sales would have
    been no more that approximately $475,000, resulting in annual gross receipts
    of no more than $2,782,907 for that year.
    For 1983, 1984, and 1985, respectively, Products sold
    155,614,505, 156,887,148, and 155,225,544 gallons of propane to
    Texgas.   Given that Products was able to obtain all the propane
    - 28 -
    it needed from sources other than Petroleum, Petroleum's
    production was not necessary for Products to meet its supply
    obligations to Texgas.
    Discussion
    Respondent determined for the taxable years in issue that
    pursuant to section 613A(d)(2)(A)11 and section 1.613A-7(r)(2),
    11
    Section 613A provides, in pertinent part, as follows:
    SEC. 613A(d)(2). Retailers Excluded.--Subsection (c) shall
    not apply in the case of any taxpayer who directly, or
    through a related person, sells oil or natural gas
    (excluding bulk sales of such items to commercial or
    industrial users), or any product derived from oil or
    natural gas (excluding bulk sales of aviation fuels to the
    Department of Defense)--
    (A) through any retail outlet operated by the taxpayer
    or a related person, or
    (B) to any person--
    (i) obligated under an
    agreement or contract with the
    taxpayer or a related person to use

    natural gas or any product derived
    from oil or natural gas, or
    (ii) given authority, pursuant to an
    agreement or contract with the taxpayer
    or a related person to occupy any
    retail outlet owned, leased, or in any way
    controlled by the taxpayer or a related
    person.
    Notwithstanding the preceding sentence this paragraph shall
    not apply in any case where the combined gross receipts from

    Income Tax Regs.12, Petroleum was not an independent producer,
    because it sold propane through Texgas, a related retailer.
    Petitioners assert that Petroleum qualifies as an independent
    producer because it sold its propane in bulk to unrelated third
    parties and in no year did its own sales exceed $5 million.
    Respondent's argument is premised on the presumption that
    the 1982 reorganization was a "scheme" developed by Petroleum's
    tax department to allow Petroleum to qualify as an independent
    producer for the taxable years in issue.     To foster the illusion
    that Petroleum's propane was being sold to unrelated third
    parties, respondent argues, Old Petroleum entered into the
    service agreement and exchange agreements with Products to
    disguise the fact that Petroleum was selling propane through
    Texgas.     Thus, respondent contends that Products did not act as
    Petroleum's agent, but that it acquired (took title to)
    Petroleum's propane and subsequently sold the propane to Texgas.
    11
    (...continued)
    therefrom, for the taxable year of all retail outlets taken
    into account for purposes of this paragraph do not exceed
    $5,000,000. * * *
    12
    Sec. 1.613A-7(r)(2), Income Tax Regs., provides in pertinent
    part:
    (2) * * * A taxpayer shall be deemed to be selling oil or
    natural gas (or a derivative product) through a retail
    outlet operated by a related person in any case in which a
    related person who operates a retail outlet acquires for
    resale oil or natural gas (or a derivative product) which
    the taxpayer produced or caused to be made available for
    acquisition by the related person pursuant to an arrangement
    whereby some or all of the taxpayer's production is
    marketed. * * * [Emphasis added.]
    - 30 -
    Accordingly, respondent argues that Petroleum is denied
    independent producer status, because pursuant to section
    613A(d)(2)(A) and section 1.613A-7(r)(2), Income Tax Regs.,
    Petroleum is deemed to be selling its propane through a retail
    outlet (Texgas) operated by a related person (Products).
    We disagree.   A taxpayer is generally free to structure its
    business transactions as it pleases, though motivated by tax
    reduction considerations, provided the transaction is imbued with
    a sufficient business purpose.     Gregory v. Helvering, 
    293 U.S. 465
     (1935); Casebeer v. Commissioner, 
    909 F.2d 1360
     (9th Cir.
    1990), affg. in part, revg. in part and remanding 
    T.C. Memo. 1987-628
    ; Rice's Toyota World, Inc. v. Commissioner, 
    81 T.C. 184
    ,
    196 (1983), affd. on this issue, revd. in part      
    752 F.2d 89
     (4th
    Cir. 1985).   On brief respondent seems to be arguing that
    Petroleum devised the 1982 reorganization to obtain tax benefits
    associated with independent producer status.    Respondent,
    however, does not argue that the reorganization was devoid of
    economic substance, nor does respondent challenge the validity of
    Petroleum's corporate structure.    Rather, respondent asks us to
    disregard the provision of the service agreement which
    establishes that Petroleum was to retain title to its propane
    until Products sold the propane on Petroleum's behalf to
    unrelated third parties.   We decline to do so.13
    13
    Respondent does not dispute that Petroleum qualifies as an
    independent producer if the terms of the service agreement are
    respected. See Rev. Rul. 92-72, 1992-
    2 C.B. 118
    .
    - 31 -
    On the basis of the entire record, we are convinced tt not
    merely in form, but in substance, Products acted as an agent for
    Petroleum and pursuant to the service agreement did not purchase
    any of the propane that it marketed for Petroleum.   We note that
    Petroleum's production was not necessary for Products to meet its
    supply obligations to Texgas because Products was able to obtain
    all the propane it needed from sources other than Petroleum.
    Furthermore, it was Petroleum, not Products, that bore the risk
    of loss if any propane bills remained unpaid.   Thus, as discussed
    supra, we find as a fact that Petroleum, under the service
    agreement, retained title to its propane until Products sold the
    propane on Petroleum's behalf.   Accordingly, we hold that
    Products did not acquire Petroleum's propane for resale to
    Texgas, and that Petroleum, pursuant to section 613A(d)(2)(A) and
    section 1.613A-7(r)(2), Income Tax Regs., is not deemed to be
    selling its propane through Texgas, a retail outlet operated by
    Products, a related person.   Therefore, Petroleum qualifies as an
    independent producer for the taxable years in issue.
    Issue 3.   Recomputation of Petroleum's WPT NIL Computations
    Background
    On its original Federal income tax returns for each of the
    taxable years in issue, Petroleum claimed percentage depletion as
    an independent producer.   With certain statutory modifications,
    Petroleum's original percentage depletion NIL calculations
    paralleled its original WPT NIL calculations.   When calculating
    - 32 -
    its original percentage depletion NIL, Petroleum generally
    included the same amounts as overhead (indirect expenses) and
    followed the same apportionment procedures as were included and
    followed in its original WPT NIL computations.
    In the petitions filed in these cases, petitioners asserted
    for the first time that they should be permitted to modify their
    allocation process for computing the WPT NIL.14    During May and
    September of 1995, petitioners provided respondent with a revised
    apportionment formula for computing the WPT NIL.    To the amounts
    that were included in overhead in their original computations,
    petitioners contend that they should be permitted to include as
    additional overhead six new categories of indirect costs, which
    petitioners claim are attributable to the mining process.    In
    their revised computations, petitioners also changed their method
    for allocating overhead among producing properties and between
    gas and oil on a single property from actual revenue to
    production, using a conversion ratio derived from relative market
    prices of gas and oil.
    Discussion
    Respondent determined the following deficiencies in WPT for
    the taxable periods of 1983, 1984, and 1985, respectively:
    14
    Respondent did not raise this issue in the notices of
    deficiency.
    - 33 -
    $3,471,045, $3,060,042, and $2,109,854.15     On August 22, 1994,
    each petitioner timely filed a petition with this Court
    contesting the entire amount of the deficiencies asserted. In
    addition thereto, petitioners claimed overpayments of WPT of
    $6,107,901, $5,969,611, and $7,931,434 for the taxable periods of
    1983, 1984, and 1985, respectively, resulting from a
    recomputation of their WPT NIL calculations.       At trial and on
    brief, respondent contends that Petroleum's WPT NIL
    recomputations are not in accord with section 1.613-5(a), Income
    Tax Regs., because they impermissibly deviated from the
    percentage depletion calculations claimed on Petroleum's original
    returns.16   Accordingly, respondent argues that petitioners
    15
    The deficiencies as determined by respondent are in windfall
    profit taxes for the taxable periods in issue and in the amounts
    set forth below:

    Respondent further argued that petitioners' new WPT NIL
    calculations should be rejected, because they are not defensible
    under cost accounting principles. We find it unnecessary to
    (continued...)
    - 34 -
    should be proscribed from modifying the overhead allocation
    process used in their original WPT NIL calculations and instead
    be required to retain the method originally employed, which
    parallels their percentage depletion calculations and which was
    accepted by respondent during the examination process. Cf. sec.
    1.613-4(d)(2), Income Tax Regs. (generally, if a taxpayer has
    consistently employed a reasonable method of determining the
    costs of the various phases of the mining and nonmining process,
    such method shall not be disturbed).
    In response to phased decontrol of crude oil prices
    announced by President Carter in April 1979, and increased
    worldwide crude oil prices, Congress determined that the
    additional revenues of "windfall" that U.S. oil producers would
    thereby receive were an appropriate object of taxation.    H. Rept.
    96-304 at 7 (1979), 1980-

    (1979), 1980-
    3 C.B. 131
    , 142.    Consequently, Congress enacted the
    Crude Oil Windfall Profit Tax Act of 1980 (Windfall Profit Tax
    Act), Pub. L. 96-223, 
    94 Stat. 229
    , which from March 1, 1980,
    until its repeal effective August 23, 1988, imposed an excise on
    the "windfall profit" from certain crude oil produced in the

    address this issue given that we hold, based on respondent's
    threshold argument, that petitioners cannot compute the NIL using
    one allocation method for percentage depletion purposes, which
    has the effect of increasing their deduction, and a different
    method for WPT purposes, which has the effect of reducing their
    WPT.

    United States.   See sec. 4986(a).   Under the Windfall Profit Tax
    Act, the applicable tax rate is applied to the windfall profit
    per barrel.   The windfall profit per barrel is generally
    calculated under section 4988(a) by subtracting the applicable
    adjusted base price of each crude barrel of oil, and a severance
    tax adjustment, from the removal price.   After this calculation
    has been performed, section 4988(b)(1) limits the taxable
    windfall profit on any barrel of crude oil to not more than 90
    percent of the net income attributable to that barrel of oil.
    Pursuant to section 4988(b)(2), the NIL attributable to a
    barrel of oil for WPT purposes is generally calculated by
    determining "taxable income from the property" from which a
    barrel is produced for the taxable year, divided by the number of
    barrels of taxable crude oil from such property taken into
    account for such taxable year.   In computing the "taxable income
    from the property", a taxpayer deducts both direct and indirect
    (overhead) expenditures related to that property.
    The term "taxable income from the property" generally has
    the same meaning that it has for purposes of the NIL on the
    deduction for percentage depletion under section 613(a).17    As
    17
    Sec. 4988(b) provides, in pertinent part, as follows:
    SEC. 4988(b)(3). Taxable income from the property.--For
    purposes of this subsection--
    (A) In general.--Except as otherwise provided in this
    paragraph, the taxable income from the property shall be
    (continued...)
    - 36 -
    such, Congress specifically provided the starting point whereby
    taxable income from the property must be determined under section
    613(a), and, by doing so, Congress adopted the focus on income
    and expenses of individual properties historically applied under
    section 613.
    Taxable income from the property, pursuant to section 1.613-
    5(a), Income Tax Regs., is defined as "gross income from the
    property" (as defined in section 613(c) and sections 1.613-3 and
    1.613-4, Income Tax Regs.) less:
    all allowable deductions (excluding any deduction for
    depletion) which are attributable to mining processes,
    including mining transportation, with respect to which
    depletion is claimed. These deductible items include
    operating expenses, certain selling expenses,
    administrative and financial overhead, depreciation,
    taxes deductible under section 162 or 164, losses
    sustained, intangible drilling and development * * *
    expenditures, etc. * * * Expenditures which may be
    attributable both to the mineral property upon which
    depletion is claimed and to other activities shall be
    properly apportioned to the mineral property and to
    such other activities. Furthermore, where a taxpayer
    has more than one mineral property, deductions which
    are not directly attributable to a specific mineral
    property shall be properly apportioned among the
    several properties. * * *
    Accordingly, section 1.613-5(a), Income Tax Regs., controls the
    computation of the NIL for both percentage depletion and WPT
    purposes.

    determined under section 613(a). [Emphasis added.]
    - 37 -
    Petitioners, in reliance on Shell Oil Co. v. Commissioner,
    
    89 T.C. 371
     (1987), supplemented by 
    90 T.C. 747
     (1988), revd. in
    part and remanded in part 
    952 F.2d 885
     (5th Cir. 1992), argue
    that they are entitled to claim the benefit of changes in law,
    new facts, or any other item that might affect the taxpayer's
    liability.    See secs. 6511, 6512(b); see also Stone v. White, 
    301 U.S. 532
    , 534-535 (1937); Bull v. United States, 
    295 U.S. 247
    ,
    260-262 (1935).       Petitioners assert that this is precisely what
    they did here, i.e., that after reviewing their records in
    preparation for these cases, petitioners claimed in their
    petitions the benefit of changes in law as set forth in Shell
    Oil.    Petitioners further assert that contrary to respondent's
    contention, it is not necessary that they show authority
    permitting their percentage depletion apportionment method to be
    radically different from their WPT apportionment method.
    We disagree.    Given that petitioners claimed the benefits of
    percentage depletion and are subject to the WPT, they are faced
    with the dilemma of explaining what authority permits them to
    compute an NIL for percentage depletion purposes and an NIL for
    WPT purposes, both of which are calculated under section 1.613-
    5(a), Income Tax Regs., in a way that achieves radically
    different results.
    Section 4988(b)(3)(A) expressly states that "the taxable
    income from the property shall be determined under section
    613(a)." (Emphasis added.)      Thus, when Congress enacted the WPT,
    - 38 -
    it grafted the WPT NIL onto the existing body of percentage
    depletion law by incorporating section 613(a) into section
    4988(b)(3)(A).   A plain reading of section 4988(b)(3)(A) requires
    petitioners to compute the NIL for WPT purposes in the same
    manner as they computed the NIL under section 613 for percentage
    depletion purposes.   See Chevron U.S.A. Inc. v. Natural Resources
    Defense Council, Inc., 
    467 U.S. 837
     (1984) (the court must give
    effect to the unambiguously expressed intent of Congress).    It is
    unreasonable to believe Congress intended to allow taxpayers to
    compute their NIL differently for percentage depletion purposes
    and WPT purposes, where Congress explicitly incorporated by
    reference, the section 613 NIL calculation into section 4988.    If
    taxpayers were able to utilize petitioners' approach they could
    manipulate their allocation methods under sections 613 and 4988,
    thereby allowing taxpayers to increase their percentage depletion
    deductions by excluding certain items of overhead from the
    allocation process, and decrease their WPT by including the same
    items of overhead in the allocation process.   Cf. Portland Golf
    Club v. Commissioner, 
    497 U.S. 154
    , 166-170 (1990)(taxpayer was
    required to use same method of allocating fixed expenses, in
    determining whether nonmember sales activity was undertaken with
    intent to earn profit, that it did in calculating its actual loss
    from those sales).
    Finally, we note that petitioners' reliance on Shell Oil Co.
    v. Commissioner, supra, is misplaced, because in that case the
    - 39 -
    Court of Appeals for the Fifth Circuit was not faced with the
    issue herein of whether a taxpayer must figure the NIL
    consistently under sections 613 and 4988.    Rather, the issues in
    Shell Oil Co. v. Commissioner, supra, concerned the attribution
    and allocation of expenses for the calculation of the taxable
    income from the taxpayer's oil and gas properties under section
    1.613-5(a), Income Tax Regs., for purposes of the WPT NIL.    As
    discussed supra note 16, in the instant cases we never reach the
    issue of whether petitioners' allocation method is defensible
    under cost accounting principles, because we find based on
    respondent's threshold argument that petitioners are bound by
    their original computations.
    Thus, based on the record and the facts discussed herein, we
    hold that petitioners are not entitled to recompute Petroleum's
    WPT NIL computations for the taxable periods of 1983, 1984, and
    1985, where the recomputations do not follow the percentage
    depletion calculations claimed on their original Federal income
    tax returns.
    To reflect the foregoing,
    Decisions will be entered
    under Rule 155.
