    OPINION OF THE COURT
    SLOVITER, Circuit Judge.
    Connecticut General Life Insurance Company, appellant
    in No. 97-7612, and CIGNA Corporation and Consolidated
    Subsidiaries ("the CIGNA Group"), appellants in No. 97-
    7619, appeal from the judgment of the United States Tax
    2
    Court upholding notices of deficiency issued against them
    by the Commissioner of Internal Revenue in the amount of
    $62,176,665. For convenience, we will refer to the
    appellants collectively as "CIGNA." CIGNA complains that
    the Tax Court improperly deferred to the Commissioner's
    restrictive interpretation of the section of the Internal
    Revenue Code that limits the ability of affiliated insurance
    companies to file consolidated federal income tax returns.
    Because we conclude that the applicable Treasury
    regulation, as interpreted by the Commissioner, is a
    permissible interpretation of the statute, we will affirm.
    I.
    BACKGROUND
    Traditionally, life insurance companies ("life companies")
    have been profitable, whereas companies writing property
    or casualty insurance (P&C) have often been unprofitable.
    Nonlife insurance companies ("nonlife companies") have
    long been permitted to file consolidated federal income tax
    returns with their affiliated nonlife companies, but not with
    their affiliated life insurance companies. Life companies
    were required to file separate returns or returns
    consolidated with other affiliated life companies.
    The restrictions on life-nonlife consolidation were
    loosened when Congress enacted the Tax Reform Act of
    1976. Pub. L. No. 94-455, 90 Stat. 1520. That Act modifies
    the Internal Revenue Code to permit life companies to file
    consolidated returns with nonlife companies, subject to
    certain exceptions (the "life-nonlife consolidation
    provisions"), for all taxable years beginning after December
    31, 1980. See 26 U.S.C. SS 1501, 1503-1504. At issue in
    this case is the interpretation of one of these statutory
    provisions, specifically the provision that limits certain
    setoffs between affiliated insurance companiesfiling
    consolidated returns.
    3
    A.
    The Statute
    Section 1501 grants affiliated groups the privilege of
    making consolidated returns with their affiliated
    companies. If the affiliated group contains both life and
    nonlife members, S 1504 requires that a company belong to
    the group for at least five years before it is treated as
    affiliated therewith. Section 1503 then limits the extent to
    which losses incurred by nonlife members may be set off
    against gains realized by life members. Subsection (c)(1), in
    particular, caps the amount of nonlife setoff at a percentage
    of either nonlife loss or life income, whichever is less. It
    states:
    (1) In general--If . . . the consolidated taxable income
    of the [nonlife members] results in a consolidated net
    operating loss for such taxable year, then . . . the
    amount of such loss which cannot be absorbed in the
    applicable carryback periods against the taxable
    income of such [nonlife members] shall be taken into
    account in determining the consolidated taxable
    income of the affiliated group for such taxable year to
    the extent of 35 percent [30 percent in 1982] of such
    loss or 35 [30 percent in 1982] percent of the taxable
    income of the [life members], whichever is less.
    26 U.S.C. S 1503(c)(1).
    Subsection 1503(c)(2), the provision at issue here, further
    limits a group's ability to set nonlife losses off against life
    profits, providing: "Notwithstanding the provisions of
    paragraph [1503(c)(1)], a net operating loss for a taxable
    year of a [nonlife member of the group] shall not be taken
    into account in determining the taxable income of a [life
    member of the group] . . . if such taxable year precedes the
    sixth taxable year such members have been members of the
    same affiliated group . . . ." (emphasis added). Resolution of
    the instant dispute requires us to determine the scope of
    this latter limitation.
    4
    B.
    The Acquisitions
    The facts of this case are not in dispute. See First
    Stipulation of Facts, App. at 71-88; Second Stipulation of
    Facts, App. at 89-104. On March 30, 1982, Connecticut
    General Corporation (Connecticut General), was the
    common parent of more than forty affiliated subsidiaries
    (the CG Group), one of which was a life company,
    Connecticut General Life Insurance Company (CGL). The
    CG Group met the definition of an affiliated group under
    S 1504 and had filed a consolidated tax return following the
    Code revision. Thereby, the CG Group was able to offset
    some of CGL's income with a portion of the CG Group's
    nonlife loss. App. at 75-76.
    At that time, INA Corporation (INA) was parent to over
    160 affiliated nonlife subsidiaries (the INA Group), which
    subsidiaries met the requirements of S 1504 and filed
    consolidated returns under S 1501. The INA Group's
    strength was in property and casualty insurance, while the
    CG Group's strength was in the areas of life, health and
    annuity, and personal and commercial property insurance.
    App. at 75-78.
    The following day, March 31, 1982, Connecticut General
    and INA (the two parent companies) merged to form a new
    company, CIGNA Corporation (CIGNA Corp.). The merger
    was a "reverse acquisition" within the meaning of 26 C.F.R.
    S 1.1502-75(d)(3), pursuant to which CIGNA Corp.
    succeeded Connecticut General as the common parent of
    the CG Group, which continued to exist for tax purposes.
    CIGNA Corp. also became the common parent of each of
    the former members of the INA Group, which group ceased
    to exist for tax purposes. App. at 73-74. Thus, in effect, the
    CG Group, which became the CIGNA Group, acquired the
    former INA subsidiaries individually.
    Subsequently, on November 20, 1984, a subsidiary of
    CIGNA Corp. acquired Preferred Health Care, Inc. (PHC).
    Like INA and Connecticut General before the merger, PHC
    was itself common parent to a group of affiliated
    corporations (the PHC Group) (all nonlife companies), which
    5
    qualified under S 1504 and filed consolidated returns under
    S 1501. All members of the PHC Group became members of
    the CIGNA Group upon acquisition and the PHC Group
    itself ceased to exist. App. at 75, 79-80.
    C.
    The Promulgation of Regulations
    On June 8, 1982, approximately two months after the
    Connecticut General/INA merger, the Commissioner,
    pursuant to 26 U.S.C. S 1502, promulgated proposed rules
    relating to the filing of life-nonlife consolidated returns. See
    Filing of Life-Nonlife Consolidated Returns, 47 Fed. Reg.
    24,737 (1982). The proposed regulations adopted a
    subgroup method for computing a life-nonlife group's
    consolidated taxable income. In effect, they treated the
    members of the group as two separate subgroups, with the
    life members as one subgroup and the nonlife members as
    another. Each subgroup was required to set off the gains
    and losses of members within that subgroup to determine
    whether the subgroup incurred a consolidated net
    operating loss (CNOL) or a gain. Only after the gains from
    within the nonlife subgroup were set off by losses from
    within that subgroup could such losses be used to reduce
    the life subgroup's income.
    The regulations further limited the portion of a nonlife
    subgroup's consolidated net operating loss (nonlife CNOL)
    that could be set off (up to the statutorily prescribed
    percentage) against net operating gains generated by the
    life subgroup: "The offsetable nonlife consolidated net
    operating loss that arises in any consolidated return year
    . . . is the [nonlife CNOL] reduced by the amount of the
    separate net operating loss . . . of any nonlife member that
    is ineligible in that year." 
    Id. at 24,748
    (to be codified at 26
    C.F.R. S 1.1502-47(m)(3)(vi)(A)) (emphasis added). The
    proposed rules thus distinguished between "eligible"
    companies -- those that had been members of the group for
    at least five years -- and "ineligible" companies -- those
    that had not been members for at least five years.
    6
    CIGNA wrote to the Commissioner on February 28, 1983,
    suggesting that proposed regulation S 1.1502-47(m)(3)(vi)(A)
    not be adopted with respect to acquired groups. CIGNA
    suggested instead that "separate nonlife members be
    treated as one entity if they are acquired in a single
    transaction by one group but were members of a different
    group prior to their acquisition." Letter from Kenneth W.
    Gideon, Chief Counsel, IRS, to Judith Soltz, Senior
    Counsel, CIGNA Corp. 1 (March 22, 1983), App. at 197.
    Under CIGNA's suggested approach, the losses of one
    ineligible acquired member would be used to offset the
    income of other ineligible acquired members, before the
    losses of eligible members were used for that purpose. The
    effect would be to increase the amount of eligible nonlife
    loss remaining after all nonlife gains had been offset, and
    thus to increase the nonlife offset the group could claim
    against life income.
    Final regulations had to be issued by March 14, 1983 to
    be effective for the 1982 taxable year. App. at 197; see also
    26 U.S.C. S 1503(a). The Commissioner did not adopt
    CIGNA's suggestion before issuing these regulations, but
    after the final regulations were issued, Kenneth W. Gideon,
    Chief Counsel to the IRS, sent CIGNA a letter, stating:
    "[The] final life-nonlife consolidated return regulations . . .
    do not adopt your suggestion but the preamble to the final
    regulation indicates that it will be given further study."
    App. at 197. Gideon also noted that "a lack of time [had]
    prevented a complete and thoughtful analysis of [CIGNA's]
    proposed solution." App. at 197-98.
    The final regulations and preamble did differ from the
    proposed regulations in three respects: (1) a new S 1.1502-
    47(m)(4) was added, which states in its entirety, "Acquired
    groups. [Reserved]"; (2) S 1.1502-47(m)(3)(vi)(A) was
    amended to note that its definition of ineligible NOL applies
    only "for purposes of . . . subparagraph (3)"; and (3) the
    preamble was amended to state:
    [T]he Treasury Department will study further whether
    it is appropriate to aggregate the income and losses of
    ineligible members in certain cases. For instance,
    notwithstanding the ordinary reading of section
    1503(c)(2), it may be consistent with the intent of
    7
    section 1503(c)(2), or correct as a matter of policy, to
    aggregate the income and losses of ineligible members
    that filed a consolidated return prior to their
    acquisition by (and includibility in) another group that
    files a consolidated return.

    D.
    CIGNA's Consolidated Returns
    In 1981, as soon as the Tax Reform Act of 1976 became
    effective, Connecticut General elected to take advantage of
    the opportunity the Act presented and treated CGL, its sole
    life insurance company affiliate, as an includible member of
    the CG Group, thereby setting off a portion of the CG
    Group's nonlife losses against CGL's income. For the years
    ending December 31, 1982 (which was after the INA
    acquisition) through December 31, 1985, CIGNA continued
    to file life-nonlife consolidated income tax returns. CGL, the
    only life company involved, had income throughout this
    period. The nonlife companies, which included, inter alia,
    those companies that were former members of the INA
    Group (for the 1982-85 returns) and the former members of
    the PHC Group (for the 1984-85 returns), had both income
    and loss. App. at 76, 80-81.
    CIGNA computed its taxable income as follows:
    1. It consolidated (netted out) the income and los ses of
    all nonlife companies to arrive at the consolidated net
    operating loss or income.
    2. It consolidated (netted out) the losses (all in eligible)
    and income of the former INA group members to
    calculate the net operating loss attributable to those
    companies as a group.
    3. It consolidated (netted out) the losses (all in eligible)
    and income of the former PHC group members to
    calculate the net operating loss attributable to those
    companies as a group.
    8
    4. It aggregated the operating losses of other non life
    companies acquired within less than five years of the
    return (and hence ineligible).
    5. It added 2, 3, and 4 above to calculate the ine ligible
    net operating loss.
    6. It subtracted the ineligible net operating loss from 1
    above to calculate the eligible net operating loss.
    App. at 85-86.
    This treatment of the individual member companies of a
    former group as if they were a single company has been
    called the single entity method. Under CIGNA's approach,
    the losses of the former group members were reduced by
    the income of the members of that group, and that reduced
    loss was the figure treated as ineligible and deducted from
    the consolidated net operating loss of all the members of
    the CIGNA Group.
    As calculated by CIGNA, the acquisition of the INA Group
    had no effect on its tax liability, and the overall taxable
    income of the CIGNA Group (including the INA and PHC
    Groups) in the years 1982 through 1985 was equal to the
    sum of what would have been these three groups' separate
    taxable incomes had the groups not combined. See
    Appellants' Br. at 12, 20.
    E.
    The Commissioner's Audit
    On June 23, 1992, the Commissioner of Internal Revenue
    issued notices of deficiency to CGL for its taxable year
    ending December 31, 1980, and to CIGNA Group for its
    taxable years ending December 31, 1982 through December
    31, 1985. App. at 28-31, 45-53.
    Following the mode of analysis set forth in 26 C.F.R.
    S 1.1502-47(m)(3)(vi)(A), the Commissioner calculated
    CIGNA's ineligible loss in the following manner:
    1. The income and losses of all nonlife companies were
    consolidated (netted out) to arrive at the consolidated
    net operating loss or income.
    9
    2. The losses of each of the companies acquired wi thin
    less than five years of the return were aggregated to
    calculate the ineligible net operating loss.
    3. The ineligible net operating loss was subtracte d
    from the figure arrived at after the calculation in 1
    above to calculate the eligible net operating loss.
    App. at 87.
    The Commissioner thus applied the separate entity
    method under which each of the former members of the INA
    and PHC Groups (all nonlife companies) was treated as a
    separate entity whose loss, if any, was subtracted from the
    consolidated net operating loss because the member was
    affiliated less than five years. Because each acquired
    company is treated as a separate entity, the fact that it was
    part of a group acquisition or that the group, prior to being
    acquired, had previously filed a consolidated return is not
    taken into account or relevant to its tax treatment after the
    acquisition.
    The contrasting methods made a substantial difference in
    the amount of net operating loss of the nonlife companies
    that could be taken into account in determining CIGNA's
    taxable income for 1982 through 1988. The following shows
    the result of the Commissioner's approach and that used
    by CIGNA in filing its returns with respect to the nonlife net
    operating loss eligible to reduce CGL's taxable income.
    Eligible Nonlife Net Operating Loss
    Year CIGNA Commissioner
    Calculation Calculation
    1982   ($34,888,309)    ($10,225,979)
    1983   ($28,810,677)    ($ 8,351,216)
    1984   ($116,008,516)   ($26,734,260)
    1985   ($96,060,581)    ($94,424,416)
    (These numbers are undisputed and reflect the appropriate
    30% or 35% limitation set forth in S 1503(c)(1)).
    Thus, under the Commissioner's approach, because of
    the reduction in the eligible nonlife net operating loss, the
    CIGNA Group had $136,032,212 more consolidated taxable
    10
    income than under CIGNA's approach. App. at 42, 54. The
    Commissioner assessed the following deficiencies
    accordingly:
    Petitioner            Year             Deficiency
    CGL                   1980           $ 3,360,8731
    CIGNA   Group         1982            $15,080,878
    CIGNA   Group         1983           $ 1,916,121
    CIGNA   Group         1984            $41,066,157
    CIGNA   Group         1985            $   752,636
    Total Tax Deficiency (exclusive of interest and
    penalties): $62,176,6652
    On September 21, 1992, the CIGNA Group and CGL
    petitioned the Tax Court for a redetermination of the
    deficiencies set forth in the Commissioner's Notices of
    Deficiency. App. at 23-31, 38-53. The cases were
    subsequently consolidated. On February 23, 1996 and
    February 26, 1996, respectively, the Commissioner and
    CIGNA filed motions for summary judgment before the Tax
    Court. App. at 57-66. That court found in favor of the
    Commissioner. Connecticut Gen. Life Ins. Co. v.
    Commissioner, 
    109 T.C. 100
    (1997). The CIGNA Group and
    CGL each filed a Notice of Appeal on November 21, 1997.
    App. at 2, 5.
    The sole issue before the Tax Court was the proper
    calculation of the offsetable consolidated net operating loss
    of recently acquired nonlife companies (INA and PHC) when
    the group by which they were acquired (ultimately CIGNA)
    files a life-nonlife consolidated return under the auspices of
    S 1503(c)(1) and (2). The Tax Court found that "under
    [CIGNA's] single entity method losses of the ineligible
    nonlife companies of the former INA and PHC Groups were,
    in effect, indirectly made available to reduce income of
    _________________________________________________________________
    1. The deficiency determined against CGL flows indirectly from the
    Commissioner's disallowance of a portion of the nonlife loss setoffs the
    CIGNA Group claimed on its returns. Resolution of CIGNA's claim
    regarding these setoffs will determine what, if any, deficiency is
    properly
    assessed against CGL. App. at 72-73.
    2. In CIGNA's appellate brief, it reported that interest on the deficiency
    was more than $150 million at that time. Appellants' Br. at 3.

    . Because it also found the Commissioner's
    interpretation of the legislative regulations to be
    "sufficiently consistent with section 1503(c)(2) and its
    legislative purpose" to merit Chevron deference, see
    Chevron, U.S.A., Inc. v. Natural Resources Defense Council,

    II.
    DISCUSSION
    CIGNA contends that it was error for the Tax Court to
    uphold the deficiency assessments because the method
    CIGNA used in calculating its tax liability complied with all
    applicable laws and regulations. CIGNA's primary argument
    is that because none of the regulations adopted by the
    Commissioner in 1983 explicitly covers a group acquisition,
    it was free to follow any reasonable method to calculate the
    net operating loss of the members of the acquired INA and
    PHC Groups. See Gottesman & Co. v. Commissioner, 
    77 T.C. 1149
    (1981) (holding that, after Commissioner
    proposed two conflicting regulations but adopted neither,
    leaving no regulation in place, the taxpayer's choice of one
    of the proposals was reasonable and would be sustained).
    It disagrees with the Commissioner's position that 26
    C.F.R. S 1.1502-47(m)(3)(vi)(A) applies to acquired groups of
    nonlife companies, and it argues that the regulation is
    limited to acquisition of stand alone companies. As an
    alternative, CIGNA argues that if Regulation -47(m)(3)(vi)(A)
    is interpreted to govern the group acquisitions at issue,
    then that regulation is arbitrary, capricious, and therefore
    unenforceable.
    When Congress enacted the Internal Revenue Code
    revisions on consolidated returns, it gave the Secretary of
    12
    the Treasury broad authority to promulgate necessary
    regulations with respect thereto. See 26 U.S.C. S 1502.
    Pursuant to this authority, the Secretary promulgated the
    regulations at issue here, which are deemed legislative in
    character. See Tate & Lyle, Inc. v. Commissioner, 
    87 F.3d 99
    , 104 (3d Cir. 1996).
    Ordinarily, our review of an agency's construction of the
    statute it has been charged with executing is deferential. In
    Sekula v. FDIC, 
    39 F.3d 448
    (3d Cir. 1994), we summarized
    our standard of review as follows:
    When reviewing an agency's construction of a statute,
    if the intent of Congress is clear, then we must give
    effect to that intent. If the statute is silent or
    ambiguous with respect to a specific issue, then a
    deference standard applies, and the question for the
    court becomes whether the agency's answer is based
    on a reasonable construction of the statute. In
    determining whether an agency's regulation complies
    with its congressional mandate, we look to see whether
    the regulation harmonizes with the plain language of
    the statute, its origin, and its purpose. So long as the
    regulation bears a fair relationship to the language of
    the statute, reflects the views of those who sought its
    enactment, and matches the purpose they articulated,
    it will merit deference.
    
    Id. at 451-52
    (citations omitted).
    To merit deference, an agency's interpretation of the
    statute must be supported by "regulations, rulings, or
    administrative practice." Bowen v. Georgetown Univ. Hosp.,
    
    488 U.S. 204
    , 212 (1988). We will not defer to "an agency
    counsel's interpretation of a statute where the agency itself
    has articulated no position on the question." 
    Id. Once an
    agency has adopted regulations interpreting the
    statute, the agency's consistent interpretation of its own
    regulation will also be accorded substantial deference. We
    "must defer to the [agency's] interpretation unless an
    ``alternative reading is compelled by the regulation's plain
    language or by other indications of the [agency's] intent at
    the time of the regulation's promulgation.' " Thomas
    Jefferson Univ. v. Shalala, 
    512 U.S. 504
    , 512 (1994)
    13
    (quoting Gardebring v. Jenkins, 
    485 U.S. 415
    , 430 (1988));
    accord Shell Oil Co. v. Babbitt, 
    125 F.3d 172
    , 176 (3d Cir.
    1997).
    Nonetheless, "[t]he responsibility to promulgate clear and
    unambiguous standards is upon the Secretary." Director,

    Labor v. Eastern Associated Coal Corp., 
    54 F.3d 141
    , 147
    (3d Cir. 1995) (internal quotation marks omitted). Thus our
    deference to an agency's interpretation of its own
    regulations is "tempered by our duty to independently
    insure that the agency's interpretation comports with the
    language it has adopted." Director, Office of Workers'
    Compensation Programs, U.S. Dept. Of Labor v. Gardner,
    
    882 F.2d 67
    , 70 (3d Cir. 1989).
    A.
    Whether an Applicable Regulation Has Been Adopted
    In order for CIGNA to prevail on its primary argument, it
    must convince us that no regulation governs the manner in
    which consolidated net operating loss of acquired groups
    must be treated. At the outset, CIGNA faces a major hurdle
    because the Commissioner concededly did promulgate a
    regulation, -47(m)(3), which deals with the treatment of
    acquired nonlife members. CIGNA concedes that Regulation
    -47(m)(3) governs the treatment of acquired stand-alone
    nonlife members, but it argues that it does not cover the
    treatment of "acquired groups" of nonlife members. As to
    those, CIGNA asserts, there was no regulation promulgated
    by the Commissioner, who instead reserved that question
    for another day under Regulation -47(m)(4).
    The Internal Revenue Service (IRS) interprets these
    regulations differently. It insists that Regulation -47(m)(3)
    applies to all ineligible nonlife companies, whether they are
    acquired individually or as part of a group. It interprets
    Regulation -47(m)(4) as doing no more than reserving a
    place in the Code of Federal Regulations for the
    Commissioner to insert a regulation requiring different
    treatment of acquired groups should the Commissioner
    later determine that such different treatment is appropriate.
    14
    CIGNA argues that, under 
    Bowen, 488 U.S. at 212
    , the
    interpretation the Commissioner advances in this case is
    not entitled to deference because it is a "mere" litigating
    position. CIGNA's reliance on Bowen is misplaced. Bowen,
    which concerned the amount of deference due an
    administrative agency's informal interpretation of a statute,
    does not address what deference we should accord an
    agency's interpretation of its own regulations, such as is at
    issue here. Indeed, the Supreme Court has deferred to an
    agency's interpretation of its own regulations, even when
    that interpretation was proffered for the first time in
    litigation, see Gardebring v. Jenkins, 
    485 U.S. 415
    , 430
    (1988), as have we, see Elizabeth Blackwell Health Ctr. for
    Women v. Knoll, 
    61 F.3d 170
    , 183 & n.9 (3d Cir. 1995).
    Thus, we will defer to the IRS's interpretation unless that
    "alternative reading is compelled by the regulation's plain
    language or by other indications of the [agency's] intent at
    the time of the regulation's promulgation." 
    Gardebring, 485 U.S. at 430
    .
    1. The Text of -47(m)(4)
    CIGNA insists that unless subsection 26 C.F.R. S 1.1502-
    47(m)(3)(vi) applies only to the acquisition of individual
    companies, the heading "Acquired groups" on -47(m)(4)
    would be without significance. CIGNA emphasizes the
    designation of "[Reserved]" on that regulation and points to
    various definitions which equate the terms "reserved" and
    "reserve" with notions of setting aside or apart and of
    deferring a determination. CIGNA then further claims that
    this interpretation of "reserved" accords with both the
    Commissioner's past administrative practice and the
    understanding of former high-ranking treasury officials.
    We are not convinced. We agree that use of the term
    "reserved" implies that something has been set aside.
    CIGNA, however, assumes that what was set aside was "the
    subject matter of the regulation" and further that the
    subject matter of the regulation was "the treatment of the
    loss of nonlife members acquired as a group." Appellant's
    Br. at 24. It is equally likely that what was set aside was
    the numerical subsection -47(m)(4) and the space in the
    regulation it demarcates.
    15
    CIGNA further attempts to establish that the
    "Commissioner's customary administrative practice[was to]
    interpret[ ] ``reserved' in a regulation as a signal that there
    is no regulatory rule to govern the referenced subject
    matter" by identifying some instances in which the
    Commissioner used that term to have that meaning.
    Appellant's Br. at 24. That is not conclusive. In fact, the
    Office of the Federal Register, Document Drafting Handbook
    (1991), suggests a different use for the term "reserved." It
    describes "reserved" as "a term used to maintain the
    continuity of codification in the CFR" or "to indicate where
    future text will be added." 
    Id. at 27.
    We find nothing in the
    precedent that CIGNA cites to preclude the Commissioner
    from using the term "reserved" in accordance with the
    Document Drafting Handbook, rather than to connote the
    absence of a substantive rule.
    Finally, we accord little weight to the 1996 recollections
    of the several Treasury officials who submitted affidavits
    regarding the meaning of the reserved clause for acquired
    groups. In the first place, the affidavits are inconsistent:
    William McKee states that "reserved" means that no
    regulation addresses the treatment of the reserved issue,
    App. at 226, but Andrew D. Pike understood that the
    general rule would continue to apply until a special rule
    was created for acquired groups, App. at 229. Moreover,
    reliance upon remembered details from officials who lacked
    the ultimate authority to issue any proposed regulation has
    little support in the law. See Armco, Inc. v. Commissioner,
    
    87 T.C. 865
    , 867 (1987) ("[N]o one's personal views can be
    accepted as a pronouncement of the intended meaning of
    the regulation."); cf. Western Air Lines, Inc. v. Board of
    Equalization, 
    480 U.S. 123
    , 131 n.* (1987) ("[The] attempt
    at the creation of legislative history through the post hoc
    statements of interested onlookers is entitled to no weight
    . . . .").
    In sum, we, like the Tax Court, conclude that nothing in
    Regulation -47(m)(4) contradicts the Commissioner's
    interpretation of Regulation -47(m)(3)(vi) as applying to
    acquired groups. At most, Regulation -47(m)(4) is a"neutral
    factor." Connecticut Gen. Life Ins. Co., 
    109 T.C. 109
    .
    16
    2. The Preamble
    CIGNA next contends that the preamble supports its view
    that there is no rule governing the acquisition of groups.
    We have stated that "the preamble to a regulation may be
    used as an aid in determining the meaning of a regulation."
    Commonwealth of Pennsylvania v. United States Dept. of
    HHS, 
    101 F.3d 939
    , 944 n.4 (3d Cir. 1996). Here, the
    Preamble states, "[T]he Treasury Department will study
    further whether it is appropriate to aggregate the income
    and losses of ineligible members in certain cases. For
    instance, notwithstanding the ordinary reading of
    S 1503(c)(2), it may be consistent with the intent of
    S 1503(c)(2), or correct as a matter of policy, to aggregate
    the income and losses of ineligible members that filed a
    consolidated return prior to their acquisition by (and
    includibility in) another group that files a consolidated
    return." Filing of Life-Nonlife Consolidated Returns, 48 Fed.
    Reg. at 11,440.
    This passage does not contradict the IRS's interpretation
    of Regulation -47(m)(3)(vi) as applying to acquired groups.
    Indeed, it suggests that applying a rule other than that
    annunciated in -47(m)(3)(vi) would contradict "the ordinary
    reading of section 1503(c)(2)." The passage does suggest
    that it might be justifiable, nonetheless, to have such a
    rule, and it indicates that officials within the Treasury
    would consider adopting a different rule for acquired
    groups. Significantly, no such special rule was ever
    adopted. Under these circumstances, there is nothing
    unreasonable about the Commissioner's enforcement of the
    rule that did exist, a rule that, by its own terms, applies to
    these facts.
    Because the interpretation advanced by the IRS is neither
    inconsistent with any prior interpretation of these
    regulations nor incompatible with their plain text, we defer
    to that interpretation. We thus regard -47(m)(3) as
    applicable to acquired groups.
    17
    B.
    Whether the Regulation is Arbitrary, Capricious,
    and Unreasonable
    CIGNA's alternative argument is that the regulation,
    which is interpreted by the Commissioner to be applicable
    to treatment of acquired groups, is not entitled to deference
    because it is arbitrary, capricious, and unreasonable.
    CIGNA concedes that we must defer to a regulation that is
    a reasonable implementation of the congressional mandate,
    but it argues that a regulation is only a reasonable
    statutory interpretation if it " ``harmonizes with the statute's
    plain language, origin, and purpose.' " Appellants' Br. at 31-
    32 (citing National Muffler Dealers Ass'n v. United States,
    
    440 U.S. 472
    , 477 (1979)). Thus, we must review the
    legislative history of the Tax Reform Act of 1976 with an eye
    toward discerning the origin and purpose of the revision
    allowing life-nonlife consolidated tax returns.
    In the debates before Congress, it was suggested that
    lifting the ban on life-nonlife consolidated returns would
    help alleviate the acute shortage of insurance writing
    capacity in the property and casualty industry. See, e.g.,
    122 Cong. Rec. 24,683 (statement of Sen. Ribicoff), 24,687
    (statement of Sen. Curtis); S. Rep. No. 94-938, at 456,
    reprinted in 1976 U.S.C.C.A.N. 3439, 3882. The Senate
    Report noted that P&C companies affiliated with other
    nonlife companies had long been permitted to file
    consolidated returns whereas P&C companies that
    happened to be affiliated with life companies had not been
    able to do so. See S. Rep. No. 94-938, at 454, reprinted in
    1976 U.S.C.C.A.N. at 3881. The Report states: "[T]he
    present ban on life-nonlife consolidations has been a
    hardship for casualty companies which are affiliated with
    life companies," and explains that "[t]he committee
    amendment deals with this problem." 
    Id. At the
    same time, the legislators recognized that the
    then-existing ban on consolidated returns had assured that
    life insurance companies paid tax at the regular rate on an
    amount approximately equal to their taxable investment
    income. They sought to retain that result in drafting the
    18
    new life-nonlife provisions, presumably by limiting the
    permissible offset to a percentage of life income
    incorporated in S 1503(c)(1). See id.; Staff of the Joint
    Committee on Taxation, General Explanation of the Tax
    Reform Act of 1976 (H.R. 10612, 94th Congress, Public Law
    94-455) at 435-36 (1976) ("[C]ongress adopted a provision
    which preserves the concept that some tax be paid with
    respect to the life insurance company's investment income
    . . . but which at the same time provides substantial relief
    in the future for casualty companies with losses.").3
    Shortly before the bill was enacted, the Conference
    Committee added S 1503(c)(2), the section at the center of
    the CIGNA-IRS dispute. That section provides that the net
    operating loss of a member of the group of affiliated
    companies "shall not be taken into account" unless that
    member has been a member of that group for five years.
    The Conference Report does not suggest a reason for this
    amendment. The slim legislative history reveals merely that,
    during the hearings relating to the life-nonlife consolidation
    provisions, Senator Kennedy in particular had expressed
    some concern that the largest life insurance companies
    might seek to enlarge the tax benefit provided by the new
    provisions by acquiring small loss-ridden P&C companies
    for the purposes of generating nonlife losses and setting
    these losses off against their taxable income. See 
    id. at 24,685
    ("Those [life insurance companies] who have
    substantial profits can go out and purchase other
    companies with tax losses in order to be able to write these
    losses off."). Section 1503(c)(2), as enacted, thus appears to
    have been designed to discourage tax-motivated
    acquisitions by insurance companies.
    CIGNA argues that the Commissioner's approach runs
    counter to the origins and purposes of the Tax Reform Act
    of 1976 "because it exacerbates the very problem that
    Congress sought to address by enacting the life-nonlife
    _________________________________________________________________
    3. The Senate Report estimated that these provisions would "result in a
    decrease in revenues of $25 million in the fiscal year 1978, $55 million
    in the fiscal year 1979, $49 million in the fiscal year 1980, and $40
    million in the fiscal year 1981." S. Rep. No. 94-938, at 457, reprinted in
    1976 U.S.C.C.A.N. at 3884.
    19
    consolidation provisions." Appellants' Br. at 31. CIGNA
    notes that although, collectively, the former INA Group
    members suffered net losses in each of the four years
    following their acquisition, under the Commissioner's
    calculation the combined group's taxable income increased
    by $136 million and its tax liability increased by
    approximately $60 million over the same four-year period,
    thereby reducing the group's capacity to write insurance.
    CIGNA characterizes the Commissioner's interpretation of
    Regulation -47(m)(3)(vi) as thus "penaliz[ing] the P&C
    industry contrary to the purpose of the life-nonlife
    consolidation provisions." Appellants' Br. at 33.
    CIGNA's assessment of the congressional purpose is
    overly narrow. Congress did have an interest in increasing
    the capacity of the industry to write P&C insurance, which
    it effected through S 1501, which enables P&C companies to
    offset (partially) their losses against the income of their life
    affiliates by filing consolidated returns. Nothing in the
    regulations promulgated by the Commissioner prevented
    the former CG Group from taking full advantage of this
    opportunity by filing a consolidated tax return for its
    affiliated companies and offsetting the P&C losses against
    life income, which it did beginning in 1981.
    But, Congress apparently also had another subsidiary
    goal -- to limit tax-induced shopping for acquisitions. And
    when the former CG Group chose, within a year of the
    statute's effective date, to affiliate with the INA Group to
    form CIGNA, it ran into S 1503, the section Congress
    enacted to effectuate that subsidiary goal. Although CIGNA
    could continue to have the advantage of offsetting P&C
    losses within its historic group after the acquisition, it
    could not take advantage in any way of the losses of the
    INA Group. And CIGNA's protests notwithstanding, that is
    precisely what it seeks to do.
    If none of the INA companies had income, S 1503 would
    be irrelevant, as the methods proffered by both CIGNA and
    the Commissioner would arrive at the same result; the
    same is true if all of the INA companies had income, as
    their income would be added to the income of the other
    affiliated companies. However, CIGNA proposes to permit
    the INA companies to offset income within the group by
    20
    losses within the group before that income is added to that
    of the other now affiliated companies. In terms that may be
    too simplistic for the hundreds of millions of dollars at
    issue, this reduces the amount of income that could be
    added to the total CIGNA income. As the Commissioner
    explains, the net operating loss of a company that has not
    been a member of the group for five years is thus being
    "taken into account" by reducing the total income.
    Perhaps recognizing that S 1503 serves a goal other than
    that of increasing P&C capacity, CIGNA describes the
    purpose of that section narrowly: "Section 1503(c)(2) had a
    narrow[ ], targeted purpose, and was intended only to
    address the specific concern that life companies might have
    a tax incentive to acquire nonlife companies to take
    advantage of additional future loss offset benefits."
    Appellants' Br. at 36. CIGNA insists that S 1503(c)(2) "was
    intended only to limit the incremental consolidation benefit
    that might be derived from the acquisition of additional
    nonlife companies." 
    Id. It then
    argues that the
    Commissioner's approach contradicts the statute by
    denying CIGNA more than this incremental benefit.
    CIGNA points to nothing in the scant legislative history of
    this provision that compels such a narrow reading of
    S 1503(c)(2)'s purpose. Moreover, the statute contains no
    language that limits its effect to the denial of the
    incremental consolidation benefit. It says nothing more
    than that losses of companies that affiliated with the group
    less than five years ago shall not be taken into account.
    CIGNA's argument that the Commissioner has
    interpreted S 1503(c)(2) too broadly focuses too narrowly on
    the short-term. Section 1503 only limits offsets forfive
    years following an acquisition. After that time, group
    insurance companies such as CIGNA can offset the losses
    of acquired companies as permitted, thereby effecting an
    increase in P&C capacity. There is no indication that
    Congress focused, in the final stages of enactment of the
    Tax Reform Act of 1976, on the situation of group
    companies acquiring group companies. Even if it had, there
    is even less reason to think that it would have been swayed
    by the potential short-term disadvantage to some
    companies. More likely is that Congress was interested in
    21
    the long-run solution. After all, it was Congress that
    imposed the five-year limitation in the first place.
    Finally, CIGNA makes a policy argument that the INA
    companies should be permitted to offset losses against
    income because they had been permitted to do so before
    the acquisition. It contends that the Commissioner's
    regulation, as interpreted, is unfair because it requires that
    the income of profitable members of the acquired group be
    taken into account, but not the loss of acquired members.
    The simple answer, obviously unsatisfactory to CIGNA, is
    that the Commissioner, who has the delegated authority to
    promulgate legislative regulations, did not provide for initial
    offsets within the group. And there is no language in the
    statute that requires the offset CIGNA seeks. In fact, there
    was disagreement within the IRS as to whether the
    Commissioner could have provided for such initial offsets
    without contradicting the statute. Before us, the IRS
    continues to characterize that question as arguable.
    Inasmuch as the Commissioner did not adopt CIGNA's
    approach, the issue is not before us and we make no
    comment.
    We do note, however, that if CIGNA's approach were
    adopted, it would create a distinction between nonlife
    companies acquired as a group and those very same
    companies acquired individually that is hard to justify. Had
    CIGNA acquired only INA's profitable nonlife companies in
    1981, there is no question that the acquisition would have
    increased its overall taxable income. And, as CIGNA
    presumably concedes, had CIGNA subsequently acquired
    the remainder of the INA Group, S 1503(c)(2) would have
    precluded offsetting that increase in taxable income with
    the losses of the later-acquired members. CIGNA has
    offered no justification for requiring the Commissioner to
    treat the instant case differently, merely because both
    acquisitions occurred on the same day.
    The overriding determinant is that the Commissioner's
    regulation is authorized by the statute, and his
    interpretation of that regulation is not so unreasonable as
    to be declared invalid by this court on policy grounds. That
    is not our function or our decision. As the Supreme Court
    has emphasized, "[w]hen Congress . . . has delegated
    22
    policymaking authority to an administrative agency, the
    extent of judicial review of the agency's policy
    determinations is limited." Pauley v. BethEnergy Mines, Inc.,
    
    501 U.S. 680
    , 696 (1991).
