    107 T.C. No. 19
    UNITED STATES TAX COURT
    THE NORTH WEST LIFE ASSURANCE COMPANY OF CANADA, Petitioner v.
    COMMISSIONER OF INTERNAL REVENUE, Respondent
    Docket No. 4694-94.                Filed December 12, 1996.
    P, a Canadian insurance company, operated through
    a permanent establishment in the United States for
    purposes of the income tax convention between the
    United States and Canada. P reported its net
    investment income effectively connected with its
    conduct of an insurance business within the United
    States pursuant to sec. 842(a), I.R.C., without regard
    to the minimum amount of net investment income that
    sec. 842(b), I.R.C., treated as effectively connected.
    P claimed under the Convention With Respect to Taxes on
    Income and on Capital, Sept. 26, 1980, U.S.-Can.,
    T.I.A.S. No. 11087, 1986-2 C.B. 258 (Canadian
    Convention), to be exempt from sec. 842(b), I.R.C.
    Held, art. VII(2) of the Canadian Convention requires
    that profits attributed to a permanent establishment be
    measured based on the permanent establishment's facts
    and by reference to the establishment's separate
    accounts insofar as those accounts represent the real
    facts of the situation. Held, further, sec. 842(b),
    I.R.C. in prescribing a statutory minimum amount of net
    investment income that must be treated as effectively
    - 2 -
    connected with the conduct of P's insurance business
    within the United States, fails to attribute profits to
    P's permanent establishment based on the
    establishment's facts. Held, further, sec. 842(b),
    I.R.C. fails to attribute profits by the same method
    each year. Held, further, pursuant to art. VII(2) of
    the Canadian Convention, P is taxable under subch. L,
    part I on its income effectively connected with its
    conduct of any trade or business within the United
    States without regard to sec. 842(b), I.R.C.

    respondent.
    HAMBLEN, Judge:   Respondent determined deficiencies in
    petitioner's Federal income and branch profits tax for the
    taxable years 1988, 1989, and 1990, in the amounts of $518,102,
    $23,730, and $71,662, respectively.
    Unless otherwise indicated, all section references are to
    the Internal Revenue Code in effect for the taxable years at
    issue, and all Rule references are to the Tax Court Rules of
    Practices and Procedure.   The sole issue for decision is whether

    (Canadian Convention), override section 842(b), which requires a
    foreign company conducting an insurance business in the United
    States to treat a minimum amount of net investment income as
    effectively connected with its conduct of that business.    For the
    reasons set forth below, we hold that article VII of the Canadian
    Convention, 1986-2 C.B. at 260, overrides section 842(b).
    FINDINGS OF FACT
    Some of the facts have been stipulated and are found
    accordingly.    The stipulation of facts and accompanying exhibits
    are incorporated herein by this reference.   The facts found are
    those which, unless otherwise specified, existed during the years
    at issue.
    A.     Petitioner
    The North West Life Assurance Co. of Canada (petitioner) is
    a life insurance company organized under the corporation laws of
    Canada with its principal place of business located in Vancouver,
    British Columbia, Canada.   Petitioner operates its life insurance
    business solely in the United States and Canada and is in the
    business of writing deferred annuities and life insurance
    policies.    Petitioner began operating in the United States (U.S.
    branch) in 1971, selecting the State of Washington as its State
    of entry and subjecting itself to the insurance laws of that
    State and to regulation by that State's insurance commissioner.
    Petitioner maintains a sales and underwriting office in Bellevue,
    - 4 -
    Washington.    In addition, petitioner is licensed to transact
    business as a life insurance company in 20 other States.
    Petitioner's U.S. branch uses a calendar year accounting
    period and the accrual method of accounting.    Petitioner timely
    filed its Federal income tax returns (Forms 1120L) for tax years
    1988, 1989, and 1990.
    B.     Petitioner's Product Mix
    Petitioner's U.S. branch operates primarily in the "section
    403(b) market", selling individual deferred annuities to school
    teachers.    Petitioner has the following product mix, measured by
    its reserves, during the years at issue:
    United States
    Individual Annuities      Individual Life Policies
    1988        97.00%                          3.00%
    1990        95.60                           4.40
    Canada
    Individual Annuities        Individual Life Policies
    1988        64.73%                        35.27%
    1990        68.44                         31.56
    Petitioner’s U.S. branch sold these products in the United
    States, and petitioner's principal office in Vancouver sold them
    in Canada.
    C.     Pricing of Products
    Each of petitioner's annuity contracts includes an
    accumulation period and a payout period.    During the accumulation
    - 5 -
    period, petitioner collects the premiums on its annuity contracts
    (accumulation annuities).   Petitioner does not charge fixed
    premiums; rather, the annuity holders pay in as much as they
    desire.   Petitioner invested the collected premiums and
    guarantees its U.S. annuity holders, on a yearly basis, a
    specific rate of return (one-year rate guarantees).   Petitioner
    makes primarily 5-year interest rate guarantees to its Canadian
    annuity holders. Petitioner's annuity holders are able to
    withdraw the accumulated funds from petitioner once annually
    during the accumulation period.    These withdrawals are subject to
    surrender charges.   The surrender charges are reduced during the
    first 5 to 10 years of each annuity contract's existence but are
    always eliminated before the payout period begins.
    During the payout period, petitioner pays the annuity
    holders fixed periodic payments over the remainder of the
    annuitant’s life or over a specified number of years (payout
    annuities).   Once the payout period begins, petitioner does not
    permit early withdrawals.
    D.    Investment Strategy
    Mr. Arthur W. Putz, vice president of investments and
    secretary of petitioner, is primarily responsible for handling
    the administrative details of petitioner's investment activity.
    Donald R. Francis, executive vice president and appointed actuary
    - 6 -
    of petitioner, is primarily responsible for providing actuarial
    services to petitioner's life insurance business.
    As part of its investment strategy for its U.S. operations,
    petitioner sought to avoid the risk of fluctuations in currency-
    exchange and interest rates.   Petitioner avoids currency-exchange
    risk by investing in assets in the same currencies as its
    insurance liabilities.   Petitioner attempts to reduce its
    interest-rate risk by matching the duration of its assets with
    the maturity of its liabilities.    Washington State law allows an
    insurance company to invest up to 65 percent of its portfolio in
    mortgages.   Wash. Rev. Code Ann. sec. 48.13.265 (West Supp.
    1990). Petitioner invested between 58 percent and 63 percent of
    its portfolio in mortgages during the years at issue.    In order
    to match its investments in mortgages with the 1-year rate
    guarantees on its annuities and also enjoy a relatively high
    return from such investments, petitioner purchases mortgages with
    5-year maturities, with a right of renewal for another 5 years at
    market-adjusted interest rates.    The average duration of these
    mortgages is approximately 2 ½ years.    Because petitioner's
    5-year mortgages are longer than the 1-year rate guarantees, part
    of petitioner's strategy is to balance its portfolio by also
    investing in assets with a duration shorter than its liabilities.
    Petitioner makes longer-term investments in assets backing
    both its individual life insurance policies and payout annuities
    - 7 -
    than it does in assets supporting its accumulation annuities.
    Petitioner's accumulation annuities comprise approximately 99
    percent of petitioner's annuity contracts arising from its U.S.
    branch and approximately 50 percent of the contracts arising from
    its Canadian office.
    E.   Flow of Funds
    Petitioner collects premiums arising from its U.S. branch
    business in U.S. currency (U.S. dollars).    Upon receipt, for
    administrative convenience, petitioner transfers the premium
    payments into a U.S. dollar-denominated account with Toronto-
    Dominion Bank in Vancouver, British Columbia (Toronto bank).     The
    Toronto bank pays nominal interest on balances in the account in
    excess of $250,000.
    Washington State law requires foreign insurance companies to
    maintain a trust account (trusteed assets) in order to qualify to
    transact insurance in the State.    Wash. Rev. Code Ann. sec.
    48.05.090 (West Supp. 1990).    Petitioner maintains a trust
    account and an operating account at Seattle First National Bank
    in Seattle, Washington (Seattle bank).    Periodically, petitioner
    transfers the premiums and interest from the Toronto bank account
    to the Seattle bank accounts.    Petitioner transfers the majority
    of such funds to the trust account and the balance to the
    operating account.    Petitioner pays commissions, claims, and
    operating expenses from its operating account.    The Seattle bank
    - 8 -
    does not pay any interest on the funds in the operating account.
    Petitioner invests the premiums in the Seattle trust account in
    U.S. dollar-denominated assets and retains the earnings in the
    same account.   As a general business practice, during the years
    at issue, petitioner did not withdraw assets until they matured
    or rely upon assets outside of the trust account to cover the
    liabilities incurred by its U.S. branch.
    In 1987, petitioner transferred between $7 and $8 million in
    Canadian dollar-denominated bonds from its Canadian business to
    the Seattle bank trust account in order to increase its surplus
    assets held in the United States relative to the proportion of
    its surplus held in the Canadian operation.   In 1988, petitioner
    sold stock in a related domestic company for its original cost to
    Industrial Alliance Life Insurance Co., petitioner's Canadian
    parent corporation.   The stock had been recorded on the books of
    petitioner's U.S. branch and included in the Seattle trust
    account.
    F.    Mandatory Filings
    The insurance commissioner of each State in which petitioner
    is licensed to carry on an insurance business requires
    petitioner's U.S. branch to file certain annual statements
    reflecting its U.S. branch operations.   To standardize reporting
    requirements, all States require reporting on the annual
    statement forms developed by National Association of Insurance
    - 9 -
    Commissioners (NAIC), a voluntary association of State insurance
    commissioners.   NAIC publishes standard detailed forms upon which
    each type of insurance company reports its annual financial
    condition.
    NAIC form 1A must be filed annually by petitioner with the
    State of Washington.   NAIC form 1A requires information regarding
    whether a U.S. branch has sufficient admissible assets (all
    assets of its U.S. branch other than the separate-accounts
    business) over liabilities, including the statutory deposit.     The
    inside cover of NAIC form 1A states:
    This Annual statement differs in some respects from
    that for a United States Company and should not be
    interpreted in the same manner. The most important
    fact conveyed by the statement is whether the Company
    has a sufficient amount of admissible assets to meet
    all known liabilities of its United States business
    including statutory deposit. For this reason, the
    Annual statement balance sheet does not show the amount
    of unassigned funds, or surplus, which are accrued from
    earnings of the United States business, but rather
    total United States admissible assets and total United
    States liabilities and statutory deposit.
    NAIC form 1 must be filed by domestic insurance companies
    with their respective State regulatory agencies.   Differences
    between NAIC form 1A and NAIC form 1 include:
    1.   NAIC form 1A lists assets and liabilities with the assets
    not necessarily equaling liabilities, capital, and surplus,
    whereas NAIC form 1 includes a balance sheet;
    2.   NAIC form 1A lists income and expenses, but it does not
    include realized capital gains and losses;
    - 10 -
    3.   Schedule D of NAIC form 1A reflects deposits and withdrawals
    of securities from a trust account at book value, whereas
    NAIC form 1 reflects purchases and sales of bonds and stocks
    at transaction prices;
    4.   NAIC form 1A does not include a reconciliation of capital
    and surplus from the prior year to the current year, but
    NAIC form 1 does include such a reconciliation.
    The Office of the Superintendent of Financial Institutions
    Canada (OSFI), Ottawa, Canada, also requires petitioner to file
    an annual statement (OSFI statement) reflecting its total
    business in both Canada and the United States.    The reporting and
    accounting requirements for assets, liabilities, income, and
    expenses for purposes of the OSFI statement are different in a
    number of respects from those for NAIC forms.
    G.   Petitioner's Assets and Surplus
    Petitioner reports on its NAIC form 1A the following
    percentage distribution of assets relating to its U.S.
    operations:
    1988        1989      1990
    Bonds                     11.6%       15.0%    20.6%
    Mortgage loans            58.8        58.3     63.5
    Real estate                1.2         2.0      2.3
    Cash                      15.5        12.7      6.1
    Policy loans              12.9        12.0      7.4
    Stocks                     0.0         0.0      0.1
    Total   100.0       100.0    100.0
    Based on its OFSI statements, petitioner has the following
    percentage distribution of assets in connection with its
    worldwide operations:
    - 11 -
    1988      1989      1990
    Bonds                          20.7%    24.3%      26.1%
    Mortgage loans                 53.0     52.7       55.2
    Real estate                     2.2      2.8        2.9
    Cash                           12.3      8.7        5.1
    Policy loans                    9.4      8.8        5.8
    Stocks                          0.7      0.7        2.6
    Other assets and
    rounding discrepancies        1.7      2.0        2.3
    Total     100.0    100.0      100.0
    Washington State law requires a foreign insurance company to
    maintain trusteed assets (equal to the excess of assets over
    general account liabilities) of at least $2 million.    Wash. Rev.
    Code Ann. sec. 48.05.340(1) (West Supp. 1990).   For 1988, 1989,
    and 1990, petitioner's Form 1A listed its U.S. branch as having
    an excess of admissible assets over liabilities in the amounts of
    $15,422,162, $19,016,749, and $19,363,533, respectively.
    Petitioner's ratio of excess mean assets to mean total
    liabilities are as follows:
    1988       1989     1990
    U.S. branch         7.70%      9.41%    9.79%
    Total company       7.56       8.21     8.38
    For each year at issue, a life insurance company
    incorporated under the laws of the State of Washington would have
    been in compliance with minimum capital and surplus requirements
    if it had owned the same assets and incurred the same liabilities
    - 12 -
    as petitioner's branch, as reported on petitioner's NAIC form 1A.
    H.      Computation of Income
    During each year at issue, petitioner reported on its
    Federal income tax returns its net investment income effectively
    connected with the conduct of its business within the United
    States, computed pursuant to section 842(a), without regard to
    the amount of minimum effectively connected net investment income
    computed pursuant to section 842(b)(1).       During the years at
    issue, petitioner used its NAIC form 1A data to identify to what
    extent its net investment income was effectively connected for
    purposes of section 842(a).
    Upon audit of petitioner's Federal tax returns for the years
    1988 through 1990, respondent increased petitioner's income by
    the extent petitioner's net investment income computed pursuant
    to section 842(b) exceeded its income computed pursuant to
    section 842(a):
    Income Determined      Income Determined      Additional
    Year        Under Sec. 842(a)      Under Sec. 842(b)        Income
    1988           $18,501,669              $21,282,045       $2,780,376
    1990            20,426,754               20,749,629          322,875
    Respondent did not include an adjustment based on petitioner's
    net investment income for 1989.        All of the "increases in income
    tax" for 1988 and 1990 are attributable to the adjustments of
    petitioner's taxable income resulting from the application of
    section 842(b).

    I.     Treasury Methodology
    The Department of Treasury calculates the asset/liability
    percentage (i.e., the mean of assets of domestic insurance
    companies divided by the mean of total insurance liabilities of
    those same domestic companies) and the domestic investment yield
    (i.e., the net investment income of domestic insurance companies
    divided by the mean of assets of those same domestic insurance
    companies) for purposes of section 842(b) using the financial
    data obtained from the A.M. Best Co.    The A.M. Best Co. compiled
    the data from the NAIC forms 1 filed by domestic insurance
    companies with their respective State insurance regulatory
    authorities.    The Treasury considers only data from those
    companies that appeared in the A.M. Best Co. files for both the
    second and third years preceding the year at issue (2-year
    aggregate data).    For the years at issue, the Treasury calculated
    the following asset/liability percentages and domestic investment
    yields:
    Return Years     Asset/Liability     Domestic Investment
    Percentage              Yield
    1988             120.5%               10.0%
    1989             117.2                 8.7
    1990             116.5                 8.8
    J.     Motion For Entry of Decision
    On October 31, 1994, respondent filed a motion for entry of
    decision.    On November 1, 1994, petitioner objected to
    - 14 -
    respondent's motion.   On November 30, 1994, a hearing was held on
    respondent's motion.   On December 5, 1994, respondent's motion
    was denied.
    OPINION
    I.   Statutory Framework
    A.   Section 842 and Section 864(c)
    Under section 842(a),2 a qualified foreign company carrying
    on a life insurance business within the United States is taxable
    on its income effectively connected with its conduct of any trade
    or business within the United States under subchapter L, part I.
    Domestic life insurance companies are also taxed pursuant to the
    latter provisions.   Sec. 801 et seq.   Section 864(c)3 and the
    2
    Sec. 842(a) provides in pertinent part:
    (a) Taxation under this subchapter.--If a foreign
    company carrying on an insurance business within the
    United States would qualify under part I * * * of this
    subchapter for the taxable year if (without regard to
    income not effectively connected with the conduct of
    any trade or business within the United States) it were
    a domestic corporation, such company shall be taxable
    under such part on its income effectively connected
    with its conduct of any trade or business within the
    United States * * *.

    Sec. 864(c) provides in pertinent part:
    (c)(2) Periodical, etc., income from sources
    within United States--factors.--In determining whether
    income from sources within the United States of the
    types described in section 871(a)(1), section 871(h),
    section 881(a), or section 881(c) or whether gain or
    loss from sources within the United States from the
    sale or exchange of capital assets, is effectively
    (continued...)
    - 15 -
    regulations thereunder govern when income is effectively
    connected to petitioner's business within the United States for
    purposes of section 842(a).   Section 842(b)4 prescribes, by
    3
    (...continued)
    connected with the conduct of a trade or business
    within the United States, the factors taken into
    account shall include whether--
    (A) the income, gain, or loss is derived from
    assets used in or held for use in the conduct of
    such trade or business, or
    (B) the activities of such trade or business
    were a material factor in the realization of the
    income, gain, or loss.
    In determining whether an asset is used in or held for
    use in the conduct of such trade or business or whether
    the activities of such trade or business were a
    material factor in realizing an item of income, gain,
    or loss, due regard shall be given to whether or not
    such asset or such income, gain, or loss was accounted
    for through such trade or business.

    *   *     *     *      *   *   *
    (C) In the case of a foreign corporation
    taxable under part I * * * of subchapter L, any
    income from sources without the United States
    which is attributable to its United States
    business shall be treated as effectively connected
    with the conduct of a trade or business within the
    United States.
    4
    Sec. 842(b) provides in pertinent part:
    (1) In general.--In the case of a foreign company
    taxable under part I * * * of this subchapter for the
    taxable year, its net investment income for such year
    (continued...)
    - 16 -
    statutory formula, a minimum amount of net investment income that
    a foreign insurance company, which is taxable under subchapter L,
    part I, must treat as effectively connected to its conduct of an
    insurance business in the United States (minimum ECNII).    In
    effect, a foreign insurance company engaged in business in the
    United States would be taxable, under Internal Revenue Code
    provisions in issue before us, on the greater of its actual
    effectively connected net investment income (actual ECNII)
    pursuant to section 842(a) or its minimum ECNII as determined by
    the statutory formula.

    (...continued)
    which is effectively connected with the conduct of an
    insurance business within the United States shall be
    not less than the product of--
    (A) the required U.S. assets of such company, and
    (B) the domestic investment yield applicable
    to such company for such year.
    Sec. 842(b)(5) defines net investment income for purposes of sec.
    842(b) as follows:
    Net investment income.--For purposes of this
    subsection, the term "net investment income" means--
    (A) gross investment income (within the
    meaning of section 834(b)), reduced by
    (B) expenses allocable to such income.
    - 17 -
    B.   Formula
    A foreign insurance company's minimum ECNII is the product
    of the company's required U.S. assets and the domestic investment
    yield (domestic yield).    Sec. 842(b)(1).   The required U.S.
    assets of a company are determined by multiplying the mean of its
    total insurance liabilities on its business within the United
    States for the taxable year by the domestic asset/liability
    percentage (asset/liability percentage) applicable to such
    company for that year.    Sec. 842(b)(2).5   The asset/liability
    percentage is a ratio, the numerator of which is the mean of the
    assets of domestic insurance companies and the denominator of
    5
    Sec. 842(b)(2) provides:
    (2) Required U.S. assets.--
    (A) In general.--For purposes of paragraph (1),
    the required U.S. assets of any foreign company for any
    taxable year is an amount equal to the product of--
    (i) the mean of such foreign company's total
    insurance liabilities on United States business, and
    (ii) the domestic asset/liability percentage
    applicable to such foreign company for such year.
    (B) Total insurance liabilities.--For purposes of
    this paragraph--
    (i) Companies taxable under part I.--In the
    case of a company taxable under part I, the term
    "total insurance liabilities" means the sum of the
    total reserves (as defined in section 816(c)) plus
    (to the extent not included in total reserves) the
    items referred to in paragraphs (3),(4),(5), and
    (6) of section 807(c).
    - 18 -
    which is the mean of the total insurance liabilities of the same
    domestic insurance companies.    Sec. 842(b)(2)(C).6   The domestic
    yield is a ratio, the numerator of which is the total net
    investment income of domestic life insurance companies and the
    denominator of which is the mean annual balance of the total
    assets of these same domestic companies.    Sec. 842(b)(3).7
    Section 842(b)(2)(C) and (b)(3) direct the Secretary of the
    Treasury to calculate both the asset/liability percentage and the
    6
    Sec. 842(b)(2)(C) provides in pertinent part:
    (C) Domestic asset/liability percentage.--The
    domestic asset/liability percentage applicable for
    purposes of subparagraph (A)(ii) to any foreign company
    for any taxable year is a percentage determined by the
    Secretary on the basis of a ratio--
    (i) the numerator of which is the mean of the
    assets of domestic insurance companies taxable
    under the same part of this subchapter as such
    foreign company, and
    (ii) the denominator of which is the mean of the
    total insurance liabilities of the same companies.
    7
    Sec. 842(b)(3) provides:
    (3) Domestic investment yield.--The domestic
    investment yield applicable for purposes of paragraph
    (1)(B) to any foreign company for any taxable year is
    the percentage determined by the Secretary on the basis
    of a ratio--
    (A) the numerator of which is the net
    investment income of domestic insurance companies
    taxable under the same part of this subchapter as
    such foreign company, and
    (B) the denominator of which is the mean of
    the assets of the same companies.
    - 19 -
    domestic yield each year.   Section 842(c)(4) provides that each
    calculation for any taxable year "shall be based on such
    representative data with respect to domestic insurance companies
    for the second preceding taxable year as the Secretary considers
    appropriate."
    C.   Worldwide Election
    Section 842(b)(4) permits a foreign insurance company to
    elect to use its own worldwide current investment yield
    (worldwide yield) rather than the domestic yield.8   A company's
    worldwide yield is obtained by dividing the net investment income
    8
    Sec. 842(b)(4) provides in pertinent part:
    (4) Election to use worldwide yield.--
    (A) In general.--If the foreign company makes
    an election under this paragraph, such company's
    worldwide current investment yield shall be taken
    into account in lieu of the domestic investment
    yield for purposes of paragraph (1)(B).
    (B) Worldwide current investment yield.--For
    purposes of subparagraph (A), the term "worldwide
    current investment yield" means the percentage
    obtained by dividing--
    (i) the net investment income of the
    company from all sources, by
    (ii) the mean of all assets of the
    company (whether or not held in the United
    States).
    (C) Election.--An election under this
    paragraph shall apply to the taxable year for
    which made and all subsequent taxable years unless
    revoked with the consent of the Secretary.
    - 20 -
    of the company from all sources by the mean of all assets of the
    company.   Sec. 842(b)(4)(B).   A company may not revoke the
    election without the consent of the Secretary.    Sec. 842
    (b)(4)(C).
    II.   Canadian Convention
    The Canadian Convention is designed to prevent double
    taxation and to avoid fiscal evasion (Preamble to Canadian
    Convention).   Article VII of the Canadian Convention governs when
    and how much of the profits of a qualified Canadian enterprise
    are subject to U.S. Federal income tax.    The relevant provisions
    of Article VII for making such a determination are as follows:
    1. The business profits of a resident of a Contracting
    State shall be taxable only in that State unless the
    resident carries on business in the other Contracting
    State through a permanent establishment situated
    therein. If the resident carries on, or has carried
    on, business as aforesaid, the business profits of the
    resident may be taxed in the other State but only so
    much of them as is attributable to that permanent
    establishment.
    2. Subject to the provisions of paragraph 3, where a
    resident of a Contracting State carries on business in
    the other Contracting State through a permanent
    establishment situated therein, there shall in each
    Contracting State be attributed to that permanent
    establishment the business profits which it might be
    expected to make if it were a distinct and separate
    person engaged in the same or similar activities under
    the same or similar conditions and dealing wholly
    independently with the resident and with any other
    person related to the resident * * *
    3. In determining the business profits of a permanent
    establishment, there shall be allowed as deductions
    expenses which are incurred for the purposes of the
    - 21 -
    permanent establishment, including executive and
    general administrative expenses so incurred, whether in
    the State in which the permanent establishment is
    situated or elsewhere. Nothing in this paragraph shall
    require a Contracting State to allow the deduction of
    any expenditure which, by reason of its nature, is not
    generally allowed as a deduction under the taxation
    laws of that State.
    *   *   *     *      *   *   *
    5. For the purposes of the preceding paragraphs, the
    business profits to be attributed to a permanent
    establishment shall be determined by the same method
    year by year unless there is good and sufficient reason
    to the contrary.
    *   *   *     *      *   *   *
    7. For the purposes of the Convention, the business
    profits attributable to a permanent establishment shall
    include only those profits derived from the assets or
    activities of the permanent establishment.
    [Canadian Convention, art. VII, 1986-2 C.B. at 260; emphasis
    added.]
    Article XXV, paragraph (6) of the Canadian Convention states
    in pertinent part:
    6. Notwithstanding the provisions of Article XXIV
    (Elimination of Double Taxation), the taxation on a
    permanent establishment which a resident of a
    Contracting State has in the other Contracting State
    shall not be less favorably levied in the other State
    than the taxation levied on residents of the other
    State carrying on the same activities. * * * [Canadian
    Convention, art. XXV, par. (6), 1986-2 C.B. at 268.]
    In the instant case, the parties agree that petitioner is
    entitled to the benefits of the Canadian Convention and that
    - 22 -
    petitioner operates its insurance business in the United States
    through a U.S. permanent establishment.
    Congress can override a convention provision by enacting a
    subsequent statute.     Reid v. Covert, 
    354 U.S. 1
    , 18 (1957).
    Congress ratified the Canadian Convention in 1984.    Convention,
    Sept. 26, 1980, T.I.A.S. No. 11087, 1986-2 C.B. 258 (effective
    August 16, 1984).     It initially appears that Congress sought to
    override the Canadian Convention in the Omnibus Budget
    Reconciliation Act of 1987, Pub. L. 100-203, 101 Stat. 1330, by
    amending section 842 to incorporate subsection 842(b).    In the
    conference report to section 842(b), Congress stated, however,
    that it did "not intend to apply the general principle that, in
    the case of a conflict, a later enacted statute prevails over
    earlier enacted statutes or treaties".    H. Conf. Rept. 100-495
    (1987) 915, 983, 1987-3 C.B. 193, 263.
    Respondent contends that we should construe the Canadian
    Convention so as to harmonize the convention with the statute.
    If, however, we find that the Canadian Convention and section
    842(b) conflict, respondent concedes that the Convention prevails
    and that no deficiencies in income tax or branch profits tax for
    the years at issue exist.
    Petitioner does not challenge the taxation of its actual
    ECNII or respondent’s calculations of its minimum ECNII for any
    of the years at issue.    Accordingly, if we find that the Canadian
    - 23 -
    Convention and section 842(b) are consistent, petitioner concedes
    that section 842(b) applies in this case and that it owes the
    income and branch profits tax as determined by respondent in her
    statutory notices of deficiency.
    The parties present various alternative arguments based on
    provisions of Article VII and Article XXV.   In deciding whether
    petitioner is entitled to relief from section 842(b) as a result
    of the Canadian Convention, we must determine whether:
    1. Section 842(b), in requiring petitioner to report a
    minimum amount of ECNII, conflicts with the requirements of
    paragraphs 1, 2, and 7 of Article VII on how to determine
    the profits attributable to a permanent establishment;
    2. section 842(b) violates paragraph 5 of Article VII,
    which requires a consistent method of profit attribution to
    be applied unless a good and sufficient reason to the
    contrary exists; or
    3. section 842(b) violates Article XXV, paragraph (6) by
    levying taxation less favorably on petitioner than the
    Internal Revenue Code levies taxation on U.S. residents
    carrying on the same activities.
    We discuss these issues in the context of the relevant convention
    Articles.   The issues before us are of first impression.
    III. Principles of Convention Obligations
    Before addressing the parties' arguments pertaining to
    specific convention provisions, we consider the principles for
    interpreting conventions.
    The goal of convention interpretation is to "give the
    specific words of a * * * [convention] a meaning consistent with
    - 24 -
    the genuine shared expectations of the contracting parties".
    Maximov v. United States, 
    299 F.2d 565
    , 568 (2d Cir. 1962), affd.
    
    373 U.S. 49
    (1963).   Courts liberally construe treaties to give
    effect to their purpose.    United States v. Stuart, 
    489 U.S. 353
    , 368 (1989); Bacardi Corp. of Am. v. Domenech, 
    311 U.S. 150
    ,
    163 (1940).   Even where a provision of a treaty fairly admits of
    two constructions, one restricting, the other enlarging, rights
    which may be claimed under it, the more liberal interpretation is
    to be preferred.   United States v. Stuart, supra at 368.    In
    construing a convention, we give the language its ordinary
    meaning in the context of the convention, unless a more
    restricted sense is clearly intended.    De Geofroy v. Riggs, 
    133 U.S. 258
    , 271 (1890).    Finally, it is well settled that when a
    convention and a statute relate to the same subject, courts will
    always attempt to construe them so as to give effect to both.
    Estate of Burghardt v. Commissioner, 
    80 T.C. 705
    , 713 (1983),
    affd. without published opinion 
    734 F.2d 3
    (3d Cir. 1984).
    "Although not conclusive, the meaning attributed to treaty
    provisions by the Government agencies charged with their
    negotiation and enforcement is given great weight".    United
    States v. Stuart, supra at 369 (citing Kolovrat v. Oregon, 
    366 U.S. 187
    , 194 (1961)).
    The Model Double Taxation Convention on Income and on
    Capital, Report of the O.E.C.D. Committee on Fiscal Affairs
    - 25 -
    (1977) (Model Treaty), and explanatory commentaries (Model
    Commentaries) provide helpful guidance.   See Letter of
    Transmittal from President Carter to the Senate of the United
    States requesting ratification of the Convention, dated November
    12, 1980, 4 Roberts & Holland, Legislative History of United
    States Tax Conventions, p. 242 (1986); S. Comm. on Foreign
    Relations, Tax Convention and Proposed Protocols with Canada, S.
    Exec. Rept. 98-22 (1984), 4 Roberts & Holland, supra at 1096;
    Taisei Fire & Marine Ins. Co. v. Commissioner, 
    104 T.C. 535
    (1995)(use of O.E.C.D. Commentaries in interpreting meaning of
    permanent establishments).   It is the role of the judiciary to
    interpret international conventions and to enforce domestic
    rights arising from them.    See Kolovrat v. Oregon, 
    366 U.S. 187
    (1961); Perkins v. Elg, 
    307 U.S. 325
    (1939); Charlton     v. Kelly,
    
    229 U.S. 447
    (1913); United States v. Rauscher, 
    119 U.S. 407
    (1886).   Tax treaties are purposive, and, accordingly, we should
    consider the perceived underlying intent or purpose of the treaty
    provision.   See, e.g., Estate of Burghardt v. Commissioner, supra
    at 717 (treating a reference to a "specific exemption" in a U.S.-
    Italy estate tax treaty as not limited to an exemption as such,
    but included a subsequently enacted unified credit having the
    same function as an exemption); Smith, Tax Treaty Interpretation
    by the Judiciary, 49 Tax Lawyer 845, 858-867 (1996).    In
    - 26 -
    addressing the issues of this case, we shall keep at the
    forefront our role in the interpretation of conventions.
    Respondent asserts two principles of convention
    interpretation with which petitioner disagrees.    First,
    respondent argues that the literal terms of a convention must be
    interpreted consistently with the expectations and intentions of
    the United States in entering the Canadian Convention.      In
    support of this contention, respondent cites United States v.
    Stuart, supra at 365-366, and Sumitomo Shoji Am., Inc. v.
    Avagliano, 
    457 U.S. 176
    , 185 (1982).   Second, respondent
    represents that the principles of treaty interpretation, set
    forth in her brief, were approved by the Office of International
    Tax Counsel of the Treasury Department as interpretations
    consistently held by the United States.     Respondent contends that
    any contrary interpretations held by Canada are subordinate to
    such consistently maintained U.S. interpretations.     Respondent
    relies upon United States v. A.L. Burbank & Co., 
    525 F.2d 9
    (2d
    Cir. 1975) for support of her contention.
    None of these cases supports respondent's position.      As
    evidenced by Sumitomo Shoji Am., Inc. v. Avagliano, supra at 180,
    and later in United States v. Stuart, supra at 365-366, the
    Supreme Court has consistently held that we must consider the
    expectations and intentions of both signatories, not just those
    of the United States.   The Court states:
    - 27 -
    The clear import of treaty language controls unless
    "application of the words of the treaty according to
    their obvious meaning effects a result inconsistent
    with the intent or expectations of its signatories."
    [United States v. Stuart, supra at 365-366 (citing
    Sumitomo Shoji Am., Inc. v. Avagliano, supra at 180,
    quoting Maximov v. United 
    States, supra
    at 54).]
    Moreover, we do not agree with respondent's contention that
    A.L. Burbank & Co. stands for the proposition that the
    Government's position is entitled to deference at the expense of
    our convention partner's interpretation.   In A.L. Burbank & Co.,
    the Canadian tax authorities requested the Internal Revenue
    Service (the Service) to obtain information to assist them in
    their Canadian tax investigation.   The Canadian authorities made
    their request pursuant to the 1942 tax convention between the
    United States and Canada.   Convention on Double Taxation, Mar. 4,
    1942, U.S.-Can., T.S. No. 983, 56 Stat. 1399.   The United States
    had no interest in the investigation, and there was no claim that
    U.S. income taxes were due.   The Service's understanding of the
    Canadian position was that Canadian tax authorities might not act
    on a reciprocal request to obtain information for the United
    States unless Canadian taxes were also at issue.   The Court of
    Appeals for the Second Circuit held that even if Canada failed to
    satisfy its reciprocal obligation under the convention, the
    United States was permitted to use the summons authority of
    section 7602 to obtain the information requested by Canadian tax
    officials.   United States v. A.L. Burbank & Co., supra at 15.
    - 28 -
    As we stated above, our goal is to construe the Convention
    according to the "genuine shared expectations of the contracting
    parties".   Maximov v. United 
    States, 299 F.2d at 568
    .    While the
    meaning attributed to treaty provisions by Government agencies
    charged with their negotiation and enforcement can be very
    helpful to us, and we give great weight to that meaning, United
    States v. 
    Stuart, 489 U.S. at 369
    , deference is not the same as
    blind acceptance.   See Coplin v. United States, 6 Cl.Ct. 115
    (1984), revd. on other grounds 
    761 F.2d 688
    (Fed. Cir. 1985),
    affd. 
    479 U.S. 27
    (1986). There is no authority for the
    proposition that a court construing a convention must follow the
    interpretation suggested by our Government when that
    interpretation runs contrary to what the Court concludes was the
    intent of the contracting parties. 
    Id. Indeed, the
    Supreme Court
    has noted that "courts interpret treaties for themselves,"
    Kolovrat v. Oregon, 
    366 U.S. 187
    , 194 (1961), and that the
    construction given by Government agencies is not conclusive.
    Sumitomo Shoji Am., Inc. v. Avagliano, supra at 184.     The
    deference afforded depends upon the degree to which the
    interpretation proffered by respondent, as the official U.S.
    position, is reasonable, unbiased, and consistent with what
    appear to be the circumstances surrounding the convention.
    Coplin v. United 
    States, supra
    .   As discussed below, other
    evidence in the record undermines the plausibility of
    - 29 -
    respondent's position and hence the deference that the Court is
    able to afford to that interpretation.
    IV.   Article VII of the Canadian Convention
    Petitioner argues that paragraphs 1, 2, and 7 of article VII
    of the Canadian Convention require that profits be attributed to
    its permanent establishment as if the latter were a separate
    entity distinct from petitioner's head office, with income
    measured by reference to the permanent establishment's own
    specific operations.   Petitioner goes on to argue that the
    statute mandates the application of section 842(b) in all
    instances where there is effectively connected investment income.
    If the actual income is less than the minimum under the statute,
    then the provision applies--a result that, in petitioner's
    opinion, conflicts with article VII, paragraphs (1), (2), and
    (7), which petitioner interprets to preclude taxing Canadian
    companies on a fictional amount that is greater than their actual
    income derived from their business in the United States.
    Respondent raises various arguments supporting why section
    842(b) is consistent with article VII of the Canadian Convention
    and contends: (1) Section 842(b) is a permissible method of
    attributing profits to a permanent establishment under article
    VII; (2) section 842(b) serves as a backstop to section 842(a)
    and corrects any underreporting by foreign insurance companies of
    their actual ECNII; and (3) the United States Senate, which
    - 30 -
    advised and consented to the Canadian Convention and approved
    section 842(b), believed that section 842(b) was consistent with
    the Convention.
    In our view, resolution of this controversy depends on the
    interpretation given to article VII, paragraphs (2) and (5).
    While article VII, paragraph (1) limits U.S. taxation of income
    earned by a Canadian enterprise to the income "attributable" to
    the enterprise's permanent establishment, article VII, paragraphs
    (2) and (5) direct how those attributable profits are to be
    determined.   Article VII, paragraph (2) limits "attributable"
    profits to those which a "distinct and separate person engaged in
    the same or similar activities under the same or similar
    conditions" would be expected to make (hereafter referred to as
    the separate-entity principle or basis).   Article VII, paragraph
    (5) requires that profits be attributed by the same method each
    year unless there is a good and sufficient reason to the
    contrary.   To satisfy the convention obligations of the United
    States, the domestic rules of attribution must determine the
    profits attributable to petitioner's permanent establishment
    within the limits set forth therein.   Our analysis begins by
    considering how to measure the profits on a separate-entity basis
    and whether section 842(b) determines minimum amounts of ECNII in
    a manner consistent with those limits.
    - 31 -
    V.    Measurement of Profits on a Separate-Entity Basis
    Petitioner argues that the language of Article VII requires
    income to be attributed to a permanent establishment based on its
    own particular operations.   Respondent argues that Article VII
    does not require a specific method or guarantee mathematical
    certainty and that, consequently, either country may use its
    domestic law in determining the profits attributable to a
    permanent establishment.
    It is axiomatic that the "Interpretation of the * * * Treaty
    * * * must, of course, begin with the language of the Treaty
    itself."   Sumitomo Shoji Am., Inc. v. 
    Avagliano, 457 U.S. at 180
    .
    As we stated above, the clear import of treaty language controls.
    
    Id. But Article
    VII, paragraph (2) speaks in ambiguous terms,
    and when language is susceptible to differing interpretations,
    extrinsic materials bearing on the parties' intent should be
    considered.   Day v. Trans World Airlines, Inc., 
    528 F.2d 31
    , 34
    (2d Cir. 1975); Hidalgo County Water Control & Improvement
    District v. Hedrick, 
    226 F.2d 1
    , 8 (5th Cir. 1955).
    The Senate's preratification materials confirm that the
    Canadian Convention was based in part on the Model Treaty.    See
    S. Exec. Rept. 98-22 at 3.   Our examination shows that the
    business profits article of the Model Treaty9 includes provisions
    9
    Art. 7 of Model Double Taxation Convention on Income and on
    Capital, Report of the O.E.C.D. Comm. on Fiscal Affairs (1977)
    (continued...)
    - 32 -
    substantially similar to Article VII, paragraphs (1) and (2) of
    the Canadian Convention.   While the Model Treaty itself provides
    no more explanation than the Canadian Convention on how to
    determine the profits attributable to a permanent establishment,
    the Model is explained in part by the Model Commentaries.
    Petitioner relies upon paragraphs 10 and 13 of the Model
    Commentaries to Article 7, paragraph (2) of the Model Treaty in
    support of its contention that the separate-entity language of
    Article VII, paragraph (2) requires that taxable profits be
    attributed to a permanent establishment based on the
    establishment's facts.   These paragraphs provide in pertinent
    part:
    9
    (...continued)
    (Model Treaty) provides in pertinent part:
    Par. 1. The profits of an enterprise of a Contracting
    State shall be taxable only in that State unless the
    enterprise carries on business in the other Contracting
    State through a permanent establishment situated
    therein. If the enterprise carries on business as
    aforesaid, the profits of the enterprise may be taxed
    in the other State but only so much of them as is
    attributable to that permanent establishment.
    Par. 2. Subject to the provisions of paragraph 3,
    where an enterprise of a Contracting State carries on
    business in the other Contracting State through a
    permanent establishment situated therein, there shall
    in each Contracting State be attributed to that
    permanent establishment the profits which it might be
    expected to make if it were a distinct and separate
    enterprise engaged in the same or similar activities
    under the same or similar conditions * * *
    - 33 -
    10. This paragraph contains the central directive on
    which the allocation of profits to a permanent
    establishment is intended to be based. The paragraph
    incorporates the view, which is generally contained in
    bilateral conventions, that the profits to be
    attributed to a permanent establishment are those which
    that permanent establishment would have made if,
    instead of dealing with its head office, it had been
    dealing with an entirely separate enterprise under
    conditions and at prices prevailing in the ordinary
    market. Normally, these would be the same profits that
    one would expect to be determined by the ordinary
    processes of good business accountancy. * * *
    13. Clearly many special problems of this kind may
    arise in individual cases but the general rule should
    always be that the profits attributed to a permanent
    establishment should be based on that establishment’s
    accounts insofar as accounts are available which
    represent the real facts of the situation. * * * [Model
    Commentaries to Article 7, paragraph (2) of the Model
    Treaty; emphasis added.]
    In her trial memorandum, respondent acknowledges: "[The
    model] Commentar[ies] express[] a preference for an arm's-length
    standard for the 'distinct and separate person' entity with
    separate accounts".   Respondent contends, however, that Article
    VII permits either country to apply its domestic law in
    determining the profits attributable to a permanent
    establishment.   In this regard, respondent relies upon the
    Technical Explanation, prepared by the Treasury Department and
    submitted to the Senate Foreign Relations Committee.   The
    Technical Explanation states in pertinent part:
    Paragraph 7 provides a definition for the term
    "attributable to". Profits "attributable to" a
    permanent establishment are those derived from the
    assets or activities of the permanent establishment.
    - 34 -
    Paragraph 7 does not preclude Canada or the United
    States from using appropriate domestic tax law rules of
    attribution. The "attributable to" definition does
    not, for example, preclude a taxpayer from using the
    rules of section 1.864-4(c)(5) of the Treasury
    Regulations to assure for U.S. tax purposes that
    interest arising in the United States is attributable
    to a permanent establishment in the United States.
    (Interest arising outside the United States is
    attributable to a permanent establishment in the United
    States based on the principles of Regulations sections
    1.864-5 and 1.864-6 and Revenue Ruling 75-253, 1975-2
    C.B. 203.) Income that would be taxable under the Code
    and that is "attributable to" a permanent establishment
    under paragraph 7 is taxable pursuant to Article VII,
    however, even if such income might under the Code be
    treated as fixed or determinable annual or periodical
    gains or income not effectively connected with the
    conduct of a trade or business within the United
    States. The "attributable to" definition means that
    the limited "force-of-attraction" rule of Code section
    864(c)(3) does not apply for U.S. tax purposes under
    the Convention. [Technical Explanation by the Treasury
    Department of the Convention Between the United States
    of America and Canada with Respect to Taxes on Income
    and on Capital Signed at Washington, D.C. on September
    26, 1980, as Amended by the Protocols Signed on June
    14, 1983 and March 28, 1984, 4 Roberts & Holland,
    Legislative History of United States Tax Conventions,
    p. 1020, 1032 (1986); 1986-2 C.B. 275, 279.]
    In the alternative, respondent infers from the absence of any
    reference in the Technical Explanation to a conflict between the
    Canadian Convention and prior section 819(a) of the Internal
    Revenue Code of 195410 that Canada implicitly accepted that
    attribution rules such as section 842(b) would apply.
    Nevertheless, we are satisfied that petitioner's
    construction of the separate-entity principle of Article VII,
    10
    Congress enacted sec. 819(a) as part of the Life Insurance
    Company Income Tax Act of 1959, Pub. L. 86-69, 73 Stat. 136.
    - 35 -
    paragraph (2) is correct.   The extrinsic evidence and the Model
    Treaty and Commentaries, on which the Canadian Convention is
    based in part, support that construction.   The Senate's
    preratification materials to the Convention do not ascribe a
    different meaning to the separate-entity language of Article VII,
    paragraph (2).   See S. Exec. Rept. 98-22, 20 (1984).   Moreover,
    it is consistent with the approach historically taken by the
    United States and Canada.   Art. III(1) of the Convention on
    Double Taxation, Mar. 4, 1942, U.S.-Can., T.S. No. 983, 56 Stat.
    1399.11
    While the Treasury's interpretation, set forth in the
    Technical Explanation, is particularly persuasive in light of the
    fact that the Canadian Department of Finance has generally
    accepted the Technical Explanation as an accurate portrayal of
    the understandings and context in which the Convention was
    negotiated, see ALI Project, 18 (1992); Canadian Department of
    Finance, Rel. No. 81-6 (Feb. 4, 1981), we think that respondent
    11
    Art. III(1) in the second income tax convention with
    Canada signed in 1942 provided in pertinent part:
    1. If an enterprise of one of the contracting
    States has a permanent establishment in the other
    State, there shall be attributed to such permanent
    establishment the net industrial and commercial profit
    which it might be expected to derive if it were an
    independent enterprise engaged in the same or similar
    activities under the same or similar conditions. Such
    net profit will, in principle, be determined on the
    basis of the separate accounts pertaining to such
    establishment. * * *
    - 36 -
    misconstrues the Treasury's interpretation.     We are not persuaded
    that the language set forth in the Technical Explanation of
    Article VII, paragraph (7), see supra p. 31, was intended to
    interpret Article VII as preserving the right to the use of all
    of the domestic attribution rules.     In this context, the
    Technical Explanation's use of the word "paragraph" takes on a
    significant meaning.   The word "paragraph" in the Technical
    Explanation's discussion of Article VII, paragraph (7) signals
    that under paragraph 7 of Article VII, domestic rules of
    attribution may remain viable.   It does not necessarily follow
    that all domestic rules remain so under the rest of Article VII,
    particularly Article VII, paragraph (2).     To adopt respondent's
    interpretation would require us to substitute the word "article"
    for "paragraph" and would render the limit imposed by the
    separate-entity principle meaningless.     By way of contrast, our
    interpretation of the Technical Explanation, as it relates to
    Article VII, paragraph (7), gives effect to the word "paragraph"
    without modification but still preserves the rest of Article VII.
    In a similar vein, we decline to infer an implicit
    acceptance of attribution rules like section 842(b), on the part
    of Canada, from the fact that the Technical Explanation does not
    mention any conflict between the Canadian Convention and section
    819(a).   As we discuss below, see infra pp. 42-47, there is a
    superficial similarity between prior section 819(a) and section
    - 37 -
    842(b), but, nevertheless, there are important differences
    between them.
    Accordingly, we hold that the disposition of this case turns
    on whether the section 842(b)(1) formula prescribes a minimum
    amount of ECNII based on the facts as they relate to petitioner's
    permanent establishment, by reference to the establishment's
    separate accounts insofar as those accounts represent the facts
    of the situation, and by the same method each year unless there
    is a good and sufficient reason to do otherwise.    It is to that
    review that we direct our attention.
    Petitioner retained Dale S. Hagstrom and Daniel J. McCarthy
    of Milliman & Robertson, Inc.12 (Hagstrom), whose report
    endeavored to analyze the hypothetical impact of applying the
    section 842(b) formula to the domestic insurance industry, and/or
    to U.S. branches of Canadian insurance companies.   Without going
    into the details of the conclusions reached by petitioner's
    experts suffice it to say that, overall, we do not find their
    analysis to be helpful.   For example, significantly section
    842(b) does not apply to domestic insurance companies.
    12
    Mr. Hagstrom holds a B.A. in mathematics from Princeton
    University. He is a Fellow of the Society of Actuaries and a
    member of the American Academy of Actuaries. Mr. McCarthy holds
    a B.S. in mathematics from Fordham University. In addition, he
    is a Fellow of the Society of Actuaries and a charter member of
    the American Academy of Actuaries. He has been designated as an
    enrolled actuary by the Joint Board for the Enrollment of
    Actuaries.
    - 38 -
    Furthermore, we agree with petitioner that section 842(b)
    attributes a fictional amount of income to petitioner's U.S.
    branch that is not based on its own activities but rather on the
    investment performance achieved by domestic insurance companies.
    Respondent contends that section 842(b) does not violate the
    separate-entity principle because the formula therein uses
    petitioner's liabilities to determine the assets petitioner might
    be expected to hold if it were a separate entity.   Whether the
    hypothetical amount of assets calculated pursuant to section
    842(b) represents a reasonable estimate of the amount of assets
    petitioner would hold if it were a separate entity misses the
    point; that amount is simply extraneous to petitioner's
    operations.   Section 842(b) incorporates domestic insurance
    industry data via the domestic yield or company's worldwide
    earnings data via the worldwide yield, all of which are
    extraneous to the operations of petitioner's U.S. permanent
    establishment.   We are not persuaded that the separate-entity
    principle is satisfied merely by starting with the real facts as
    they relate to petitioner's permanent establishment but then
    incorporating extraneous data that is inconsistent with that
    principle.    Cf. Ostime (Inspector of Taxes) v. Australian Mutual
    Provident Society, [1960] AC 459 (United Kingdom case with a
    similar business profits article stating that "the worldwide
    investment income, which forms the first stage of the * * *
    - 39 -
    calculation of profits, cannot be attributed to the hypothetical
    independent enterprise without violating the very hypothesis
    which * * * the treaty is designed to lay down as the basis of
    taxability", i.e., the separate-entity principle).   Respondent's
    own witness, Dr. Newlon, an international economist with the
    Treasury, admitted that the formula could be improved.   We are
    convinced that section 842(b) is contrary to and inconsistent
    with Article VII, paragraph (2), which precludes the fictional
    allocation of business profits to petitioner's permanent
    establishment.
    Imputing a level of assets and yields to petitioner's U.S.
    branch, respondent contends, is not unreasonable because the
    formula incorporates actual business data and petitioner operates
    in the United States market and directly competes with domestic
    life insurance companies.   To conclude that section 842(b) is
    reasonable in light of the fact that petitioner operates in the
    United States would not resolve the dispute before us.   It is not
    enough for section 842(b) to be reasonable.   To sustain the
    application of section 842(b) based on the facts before us, we
    must conclude that it comports with our Convention obligation.
    See United States v. A.L. Burbank & 
    Co., 525 F.2d at 15
    .   As we
    have stated above, we must conclude that the statute does not;
    consequently, it cannot prevail in the presence of the
    Convention.
    - 40 -
    Respondent asserts that Article VII, paragraph (2) permits
    the use of formulas in determining the taxable profits under
    limited circumstances.   In support, respondent relies upon
    paragraph 23 of the Model Commentaries to Article 7, paragraph
    (3) of the Model Treaty, which states in pertinent part:
    23. It is usually found that there are, or there
    can be constructed, adequate accounts for each part or
    section of an enterprise so that profits and expenses,
    adjusted as may be necessary, can be allocated to a
    particular part of the enterprise with a considerable
    degree of precision. This method of allocation is, it
    is thought, to be preferred in general wherever it is
    reasonably practicable to adopt it. There are,
    however, circumstances in which this may not be the
    case and paragraphs 2 and 3 are in no way intended to
    imply that other methods cannot properly be adopted
    where appropriate in order to arrive at the profits of
    a permanent establishment on a "separate enterprise"
    footing. It may well be, for example, that profits of
    insurance enterprises can most conveniently be
    ascertained by special methods of computation, e.g. by
    applying appropriate co-efficients to gross premiums
    received from policy holders in the country concerned.
    Again, in the case of a relatively small enterprise
    operating on both sides of the border between two
    countries, there may be no proper accounts for the
    permanent establishment nor means of constructing them.
    There may, too, be other cases where the affairs of the
    permanent establishment are so closely bound up with
    those of the head office that it would be impossible to
    disentangle them on any strict basis of branch
    accounts. Where it has been customary in such cases to
    estimate the arm's length profit of a permanent
    establishment by reference to suitable criteria, it may
    well be reasonable that that method should continue to
    be followed, notwithstanding that the estimate thus
    made may not achieve as high a degree of accurate
    measurement of the profit as adequate accounts. Even
    where such a course has not been customary, it may,
    exceptionally, be necessary for practical reasons to
    estimate the arm's length profits.
    - 41 -
    Respondent argues that paragraph 23 of the Model
    Commentaries permits the adoption of formulas if any one of the
    following circumstances is satisfied: (1) Formulas are found to
    be more convenient or administratively necessary; (2) the
    permanent establishment lacks adequate accounts by which to
    determine the attributable profits; (3) the other method is
    customary; (4) the permanent establishment is a foreign insurance
    enterprise; and (5) an exceptional need for the method is
    demonstrated.   In respondent's view, each circumstance is
    satisfied in the instant case, and section 842(b) is a
    permissible method by which to determine attributable profits
    within the meaning of the Canadian Convention.    The amicus curiae
    brief submitted by the Government of Canada asserts that when
    contracting parties to a tax convention intend to permit the use
    of formulas to determine profits of a permanent establishment
    engaged in the insurance business, the convention will contain a
    specific provision to that effect.
    We need not decide whether Article VII, paragraph (2)
    permits the use of formulas in determining the profits
    attributable to a permanent establishment.    As a preliminary
    matter, we find respondent's reliance on paragraph 23 of the
    Model Commentaries to be misplaced.    We think respondent gives
    paragraph 23 too broad a reading.    Our reading leads us to the
    conclusion that, at a minimum, before other methods (other than
    - 42 -
    using the accounts of a permanent establishment) may be adopted
    under the guidance of paragraph 23, the other method must be
    customary and based on suitable criteria or the circumstances
    must be exceptional.
    Respondent contends that section 842(b) is customary because
    it is substantially similar to the prior sections 819(a)13
    13
    Sec. 819(a) of the Internal Revenue Code of 1954, as
    amended and in effect for 1983, provided in pertinent part:
    (1) In general.--In the case of any foreign
    corporation taxable under this part, if the minimum
    figure determined under paragraph (2) exceeds the
    surplus held in the United States, then--
    (A) the amount of the policy and other
    contract liability requirements (determined under
    section 805 without regard to this subsection),
    and
    (B) the amount of the required interest
    (determined under section 809(a)(2) without regard
    to this subsection),
    shall each be reduced by an amount determined by
    multiplying such excess by the current earnings rate
    (as defined in section 805(b)(2)).
    (2) Definitions.--For purposes of paragraph (1)--
    (A) The minimum figure is the amount
    determined by multiplying the taxpayer's total
    insurance liabilities on United States business by
    a percentage for the taxable year to be determined
    and proclaimed by the Secretary.
    The percentage determined and proclaimed by the
    Secretary under the preceding sentence shall be based
    on such data with respect to domestic life insurance
    companies for the preceding taxable year as the
    Secretary considers representative. Such percentage
    (continued...)
    - 43 -
    13
    (...continued)
    shall be computed on the basis of a ratio the numerator
    of which is the excess of the assets over the total
    insurance liabilities, and the denominator of which is
    the total insurance liabilities.
    Sec. 805(a) of the 1954 Internal Revenue Code, as amended,
    defined policy and other contract liability requirements as the
    sum of:
    (1) the adjusted life insurance reserves,
    multiplied by the adjusted reserves rate,
    (2) the mean of the pension plan reserves at the
    beginning and end of the taxable year, multiplied by
    the current earnings rate, and
    (3) the interest paid.
    Sec. 805(b)(2) of the 1954 Internal Revenue Code, as
    amended, defined the current earnings rate as:
    * * * the amount determined by dividing--
    (A) the taxpayer's investment yield for such
    taxable year, by
    (B) the mean of the taxpayer's assets at the
    beginning and end of the taxable year.
    Sec. 805(b)(4) defined assets for purposes of the above sec.
    805(b)(2) as follows "all assets of the company (including
    nonadmitted assets), other than real and personal property
    (excluding money) used by it in carrying on an insurance trade or
    business."
    Sec. 809(a)(2) of the 1954 Internal Revenue Code, as
    amended, defined "required interest" for purposes of subsection
    819 as:
    the sum of the products obtained by multiplying--
    (A) each rate of interest required, or
    assumed by the taxpayer, in calculating the
    reserves described in section 810(c) by
    (continued...)
    - 44 -
    (applying from years 1959 through 1983) and 813 of the Internal
    Revenue Code of 1954, as amended, and section 813 of the Internal
    Revenue Code of 198614 (applying from years 1984 through 1987).
    13
    (...continued)
    (B) the means of the amount of such reserves
    computed at that rate at the beginning and end of
    the taxable year.
    The Life Insurance Company Income Tax Act of 1959, Pub. L. 86-69,
    sec. 2, 73 Stat. 136, added sec. 819(b), which required the same
    adjustment as sec. 819(a) except that the minimum figure was
    determined by multiplying the foreign life insurance company's
    total insurance liabilities on U.S. business by 9 percent for
    tax years beginning before January 1, 1959 and by an annual
    percentage determined by the Treasury for tax years thereafter.
    The Foreign Investors Act of 1966, Pub. L. 89-809, sec. 104,
    104(i)(3), 80 Stat. 1539, 1561, redesignated the adjustment
    provision as sec. 819(a) for tax years beginning after 1966.
    From 1966 until 1983, sec. 819(a) remained unchanged except for
    minor changes, which are not relevant to the instant case.
    14
    Sec. 813 provided in pertinent part:
    (a) Adjustment where surplus held in the United States
    is less than specified minimum--
    (1) In general.--In the case of any foreign company
    taxable under this part, if--
    (A) the required surplus determined under
    paragraph (2), exceeds
    (B) the surplus held in the United States,
    then its income effectively connected with the conduct
    of an insurance business within the United States shall
    be increased by an amount determined by multiplying
    such excess by such company's current investment yield.
    * * *
    (2) Required surplus.--For purposes of this subsection--
    (A) In general.--The term "required surplus" means
    (continued...)
    - 45 -
    The prior sections 819(a) and 813 both required a foreign
    insurance company to compare its branch's actual surplus (excess
    of assets over total insurance liabilities) held in the United
    States to a statutory minimum surplus.   Sec. 819(a)(2)(A); sec.
    813(a)(1).   If the branch's surplus was less than a statutory
    minimum, the deficiency was treated as additional assets of the
    branch which were deemed to have earned the same yield that the
    branch had earned on the assets it actually held.   Secs.
    819(a)(1), 805(b)(2), 813(a)(3).   The Deficit Reduction Act of
    1984, Pub. L. 98-369, sec. 211(a), 98 Stat. 720, 743 repealed
    14
    (...continued)
    the amount determined by multiplying the taxpayer's
    total insurance liabilities on United States business
    by a percentage for the taxable year determined and
    proclaimed by the Secretary under subparagraph (B).
    (B) Determination of percentage.--The percentage
    determined and proclaimed by the Secretary under this
    subparagraph shall be based on such data with respect to
    domestic life insurance companies for the preceding taxable
    year as the Secretary considers representative. Such
    percentage shall be computed on the basis of a ratio the
    numerator of which is the excess of the assets over the
    total insurance liabilities, and the denominator of which is
    the total insurance liabilities.
    (3) Current investment yield.--For purposes of this
    subsection--
    (A) In general.--The term "current investment
    yield" means the percent obtained by dividing--
    (i) the net investment income on assets held in
    the United States, by
    (ii) the mean of the assets held in the United
    States during the taxable year.
    - 46 -
    prior section 819 and added prior section 813.   The prior section
    819(a) required a foreign life insurance company to reduce
    certain deductions by the product of the deficiency and the
    foreign insurance company's actual yield.   Sec. 819(a).   The
    Deficit Reduction Act of 1984, Pub. L. 98-369, modified how
    taxable income was calculated for foreign insurance companies.
    Sec. 801; see H. Rept. 98-861, 1984-3 C.B. (Vol. 2) 1, 297-298.
    This change necessitated treating the product of the deficiency
    and the foreign insurance company's actual yield as additional
    effectively connected income instead of as a reduction of certain
    deductions which was done under the previous section 819.
    Subsequently, Omnibus Budget Reconciliation Act of 1987,
    Pub. L. 100-203, 101 Stat. 1330, repealed prior section 813 and
    added section 842(b).   We do not find that section 842(b) is
    similar enough to prior sections 819 and 813 so as to establish
    that section 842(b) was customary within the meaning of paragraph
    23 of the Model Commentaries.    Two features of section 842(b) go
    beyond the historical approach taken by both of the earlier
    statutes.   First, section 842(b)(1) imputes additional income
    based on an earnings yield derived from domestic industry
    averages, sec. 842(b)(3), or petitioner's worldwide operations,
    sec. 842(b)(4), whereas both prior section 819 and section 813
    imputed income based on the U.S. branch's actual earnings yield.
    Secs. 819(a)(1)(B), 805(b)(2), 813(a)(3).   Second, section 842(b)
    - 47 -
    applies an entirely new yield to all of the branch's assets not
    just to the additional imputed assets.   Prior sections 819(a) and
    813, on the other hand, imputed additional income for just those
    deemed assets.
    We recognize that a convention, like a constitution, is a
    dynamic instrument, drafted to take account of changing
    conditions and expectations.   See Day v. Trans World Airlines,

    States, 299 F.2d at 568
    .
    If we were to accept respondent's argument, however, the United
    States could, through various amendments to the Internal Revenue
    Code, always eliminate unilaterally the separate-entity
    principles in Article VII, paragraph (2) without ever violating
    the Canadian Convention.
    Nor are we are persuaded that the circumstances herein are
    exceptional.   While paragraph 23 does not prescribe when
    circumstances are considered exceptional, we do have other
    guidance as to when such circumstances may exist.   Paragraph 11
    of the Model Commentaries states that:
    11. In the great majority of cases, trading accounts
    of the permanent establishment * * * will be used by
    the taxation authorities concerned to ascertain the
    profit properly attributable to that establishment.
    Exceptionally there may be no separate accounts (cf.
    paragraphs 23 to 27 below). * * * [Emphasis added.]
    The above language suggests that other methods may only be
    adopted when a permanent establishment does not have any
    - 48 -
    accounts.   As we discuss below, the real facts (accounts) are
    ascertainable in the instant case.
    Respondent also seeks to justify the application of section
    842(b) on the grounds that the statute serves as a necessary
    backstop to section 842(a) and corrects any underreporting of
    actual ECNII by foreign insurance companies.   The parties agree
    that petitioner as well as other foreign insurance companies use
    their NAIC form 1A data to identify to what extent their net
    investment income is effectively connected to their U.S.
    businesses for purposes of section 842(a).
    In this context, respondent contends that foreign insurance
    companies have significant discretion in moving their assets
    between taxing jurisdictions once their State statutory trust
    requirements are satisfied.   Respondent points out that
    Washington State law does not require a foreign insurer to
    deposit income earned on trusteed assets in the trust account and
    that it permits petitioner to replace trusteed assets with other
    assets of equal value and quality, subject to the investment
    rules.   Consequently, forms 1A, respondent argues, fail to
    reflect the economic realities of the businesses of foreign
    insurance companies operating in the U.S. and are unreliable for
    the purpose determining their actual ECNII.    Respondent goes on
    to argue that absent section 842(b), foreign insurance companies
    - 49 -
    may escape U.S. taxation on investment income attributable to
    their U.S. business.
    Respondent retained Richard E. Stewart, Richard S.L. Roddis,
    and Barbara D. Stewart of Stewart Economics, Inc.15 (Stewart), as
    expert witnesses to give their professional opinion as to the
    reasons and incentives Canadian life insurance companies have for
    holding certain assets in the United States and why the
    investment income earned on those assets is not an inherently
    reliable measure of the investment income flowing from the branch
    operations. We have received into evidence their report.16
    Stewart reviewed the history of the State regulations applying to
    foreign insurance companies, including the NAIC annual statement
    and the trust requirements for such companies.   The report agrees
    with respondent that NAIC form 1A is not an effective means by
    which to ascertain the net investment income that is effectively

    University and a law degree from Harvard Law School. He is
    former Superintendent of Insurance of the State of New York and a
    former officer and director of The Chubb Group of Insurance

    Barbara D. Stewart holds a bachelor's degree in economics and
    business administration from Beaver College. She is a former
    corporate economist of the Chubb Group.
    16
    We have disregarded the Stewart report to the extent that
    it relies on State law of Washington for years not at issue. The
    record does not indicate that petitioner operated in Michigan;
    we have also disregarded the report to the extent that it relies
    on Michigan State law.
    - 50 -
    connected to an insurance business within the United States and
    that NAIC form 1A (foreign insurers' form) differs significantly
    from NAIC form 1 (domestic insurers' form). Stewart concluded
    that:
    Canadian life insurance companies are not required to
    earmark specific assets for their U.S. business * * *.
    [B]ecause Canadian life insurance companies have
    economic incentives to place higher yielding assets in
    lower taxing jurisdictions, something other than NAIC
    statement assets and investment yields are needed to
    determine the investment income derived from the
    trusteed assets of a Canadian life insurance company.
    Respondent also points to various facts, which she claims
    indicate that petitioner's NAIC forms 1A fail to reflect the
    economic realities of petitioner's U.S. branch: (1)   During 1988
    through 1990, petitioner’s total cash and term deposits, which
    were maintained as a part of its U.S. branch, were 75 percent, 90
    percent, and 75 percent, respectively, of its total worldwide
    funds; (2) petitioner maintained only 35 percent, 38 percent, and
    50 percent of its total bond portfolio--arguably higher-yielding
    assets--in its U.S. branch, for 1988, 1989, and 1990,
    respectively; (3) petitioner transferred Canadian dollar-
    denominated bonds from its Canadian business to its Seattle bank
    trust account in order to equalize the surplus held in each
    operation; and (4) petitioner transferred from its Seattle bank
    trust account to its Canadian parent stock that petitioner held
    in a subsidiary and for purposes of the transfer the stock was
    valued at its cost rather than at its fair market value.
    - 51 -
    We agree with respondent and respondent's expert that the
    NAIC form 1A is not the ideal means for reconciling and
    identifying all of the income attributable to a permanent
    establishment.   It does not include a closed, self-contained book
    of accounts, reconciliation of any surplus, or information
    regarding capital gains or losses.     The form is not designed to
    identify taxable income but rather to monitor compliance with
    State regulatory requirements on trusteed assets.    That
    conclusion, however, does not resolve the issue before us.
    The record is clear that petitioner occasionally exercised
    its discretion in moving assets between jurisdictions as
    evidenced by petitioner's transfer of its Canadian bonds from its
    Canadian operations to its Seattle bank trust account and by the
    sale of its stock in a subsidiary to its foreign parent.    Through
    the testimony of Mr. Putz and Mr. Francis, whom we found to be
    informative and credible witnesses, petitioner has established,
    however, as a general business practice, that it did not
    commingle assets between its Seattle bank trust account and its
    Canadian investment portfolio and had separate investment
    strategies in each country.
    We are satisfied with their explanations of the business
    reasons behind petitioner's investment strategy.    According to
    Mr. Francis' testimony, petitioner's U.S. branch had significant
    liquidity demands as a result of its need to balance its 5-year
    - 52 -
    mortgage holdings.   Petitioner has established that, in fact, it
    avoided currency risk and only invested assets in the same
    currencies as its insurance liabilities because of the narrow
    profit margins on its products.
    As petitioner correctly points out, if petitioner's accounts
    were considered so inherently unreliable as to justify ignoring
    those accounts for purposes of the Canadian Convention, such a
    method should be used in all years, not just when the statute
    produces a higher amount than does petitioner's accounts.
    Article VII, paragraph (5) of the Canadian Convention makes clear
    that the same method of profit allocation is to be used each year
    unless there is a "good and sufficient reason to the contrary."
    Paragraph 30 of the Model Commentaries to Article 7, paragraph
    (6)17 explains that "a method of allocation once used should not
    be changed merely because in a particular year some other method
    produces more favourable results".     The parties stipulated that
    for 1989 petitioner's actual ECNII and minimum ECNII were
    $19,910,031 and $19,606,065, respectively.    As a result, section
    842(b) would not increase petitioner's net investment income for
    1989 because petitioner's actual ECNII exceeded petitioner's
    17
    Art. 7(6) of the Model Treaty is substantially similar to
    Art. VII(5) of the Canadian Convention. Art. 7(6) provides in
    pertinent part: "For the purposes of the preceding paragraphs,
    the profits to be attributed to the permanent establishment shall
    be determined by the same method year by year unless there is
    good and sufficient reason to the contrary."
    - 53 -
    minimum ECNII.   On the other hand, those accounts that were
    adequate for 1989 were deemed inadequate for years 1988 and 1990
    solely on the basis that petitioner's minimum ECNII of
    $21,282,045 and $20,749,629 exceeded its actual ECNII of
    $18,501,669 and $20,426,754 and not based on the actual
    inaccuracies of those accounts.   We find that section 842(b)
    contravenes the basic premise set forth in Article VII, paragraph
    (5) of the Canadian Convention.
    In the totality of petitioner's circumstances, we do not
    believe that petitioner underreported its actual ECNII during the
    years at issue despite whatever deficiencies may exist in using
    form 1A to identify the extent to which petitioner's net
    investment income was effectively connected.
    Section 842(b) has the effect of penalizing petitioner, who
    reported income commensurate with its U.S. business but whose
    investment performance does not attain the U.S. average in each
    year.   Such an approach is simply not consistent with either
    Article VII, paragraph (2) or (5).
    Respondent argues that petitioner's facts are not
    representative of the foreign insurance industry in the United
    States.   Respondent admits that petitioner may be adversely
    affected by section 842(b) as written but contends, as a policy
    matter, the Court should not find the statute to be inconsistent
    with the Canadian Convention merely because one particular
    - 54 -
    taxpayer is adversely affected if the Court concludes that the
    statute as a whole is designed to achieve the appropriate results
    for taxpayers in general over the long term.     But both parties
    agree that this case does not turn on the validity of the policy
    reasons underlying the adoption of section 842(b) (i.e., the
    potentially abusive ability of foreign insurance companies to
    hold excess liquid assets outside of the U.S. or to hold higher
    yielding assets outside of the U.S.), and we agree with them.
    Respondent retained Christian DesRochers of the Avon
    Consulting Group18   to give his professional opinion as to the
    economic impact of section 842(b).      DesRochers analyzed section
    842(b) and the hypothetical impact of applying the formula
    therein to the U.S. branches of Canadian insurance companies.
    DesRocher's analysis of the impact of section 842(b) on
    taxpayers not before us is of little help.     As a threshold
    matter, respondent's argument raises an issue as to the proper
    factual focus of our review.   Respondent argues that the United
    States, Canada, and petitioner all accepted that a domestic
    attribution rule would be tested against Article VII on the basis
    of the circumstances of all Canadian life insurance companies
    rather than just on a particular taxpayer's facts.     To support
    18
    Mr. DesRochers holds an undergraduate degree in political
    science from the University of Connecticut. He is a Fellow of
    the Society of Actuaries and a member of the American Academy of
    Actuaries.
    - 55 -
    this contention, respondent relies in part on the discussion in
    the Technical Explanation, see supra pp. 33-34.   In respondent's
    view, because both countries expected all of their respective
    domestic attribution rules to apply, it follows that each country
    expected the domestic rule to be reviewed based on the facts of
    the entire industry.
    We need not engage in a detailed analysis of whether various
    foreign insurance companies pay Federal income tax in accordance
    with our tax laws.19   Respondent's argument essentially ignores
    the language of the referenced discussion of the Technical
    Explanation, see supra pp. 33-34.   As we previously discussed,
    see supra pp. 36-37, we do not believe that the United States and
    Canada intended for all domestic attribution rules to be
    preserved under Article VII.
    Throughout Article VII and particularly Article VII,
    paragraph (2), the language therein refers only to a single
    permanent establishment rather than the industry in which the
    establishment operates.   When the language is reasonably clear,
    19
    Respondent's proposed findings of fact include data
    relating to other Canadian life insurance companies carrying on
    insurance businesses through branches in the United States. On
    brief, petitioner objected to the relevancy of these findings
    unless the Court concluded that they were relevant "in light of
    the ‘test case’ aspect of the proceeding". Because we have
    decided the controverted issues without considering these
    stipulations in our Findings of Fact and our Opinion, the
    admissibility of these stipulations has become moot. Although we
    reviewed all the material submitted in this case, we only address
    facts affecting petitioner.
    - 56 -
    as it is in this particular context, the party proffering a
    contrary interpretation must persuade the court that its
    construction comports with the view of both parties.   See
    Sumitomo Shoji Am., Inc. v. 
    Avagliano, 457 U.S. at 180
    .
    In light of the foregoing, the language and purpose of
    Article VII, paragraph (2) and the content of the Canadian
    Convention as a whole, we also do not believe that the approach
    suggested by respondent could have been within the "shared
    expectations of the contracting parties," Maximov v. United
    
    States, 299 F.2d at 568
    , and, consequently, we do not agree that
    petitioner implicitly accepted respondent's approach to
    interpreting Article VII.
    Respondent is generally correct that section 842(b) was
    intended to serve as a backstop to the rules in section 842(a)
    and section 864(c).   The conference report to section 842(b)
    states:
    The conferees understand that the provision
    governing foreign insurance companies solves a
    statutory problem in the context of the broader issue:
    measuring the U.S. taxable income of a foreign
    corporation that is effectively connected with its U.S.
    trade or business. That issue more generally involves
    the determination of which of the corporation's assets
    generate gross effectively connected income, and which
    of its expenses and liabilities are connected with such
    income. Certain types of assets and liabilities that
    must, in this process, be attributed in whole or in
    part to a U.S. trade or business may be particularly
    suitable for movement among various trades or
    businesses of a single foreign corporation, may be
    fungible with assets and liabilities identified with
    other trades or businesses of the corporation, or may
    - 57 -
    be usable by more than one such trade or business
    simultaneously. * * * [H. Conf. Rept. 100-495 (1987)
    at 984, 1987-3 C.B. 193, 264.]
    But such a conclusion does not affect the outcome of this case.
    To begin with, as previously noted, the issues in this case do
    not concern policy in section 842(b) or any other provisions of
    the Internal Revenue Code.   Rather, the issues concern whether
    the statute comports with our convention obligations.
    Unfortunately, in the instant case, section 842(b) cannot survive
    in the presence of the Canadian Convention.
    Finally, respondent argues that we should construe section
    842(b) as agreeing with the Canadian Convention because the
    United States Senate, which advised and consented to the Canadian
    Convention and approved the statute, believed the statute did not
    violate any existing conventions.   In support, respondent points
    to several statements in the conference report to section
    842(b).20
    20
    The conference report, H. Conf. Rept. 100-495, at 983-984,
    1987-3 C.B. 263-264, listed several factors, originally developed
    by the Treasury Department, indicating why section 842(b) and
    United States treaties were consistent:(1) Section 842(b) applies
    to life insurance companies in a manner substantially similar to
    the present-law rules which Treasury did not consider to violate
    United States treaties; (2) section 842(b) attributes to the U.S.
    trade or business of a foreign life insurance company an amount
    of assets determined by reference to the assets of comparable
    domestic insurance companies, thereby reasonably measuring the
    amount of assets that the U.S. trade or business of a foreign
    insurance company would be expected to have were it a separate
    company dealing independently with non-United States offices of
    the foreign insurance company; and (3) section 842(b) furnishes
    (continued...)
    - 58 -
    We are not persuaded by respondent's assertion that this
    statement in the conference report should guide the result in
    this case.   To the extent that the statements in the conference
    report may be read as expressing the view of the Senate that
    section 842(b) is consistent with the Canadian Convention they
    are the statements of a subsequent Senate and, therefore, at
    best, "form a hazardous basis for inferring the intent of an
    earlier one."    South Carolina v. Regan, 
    465 U.S. 367
    , 379 n.16
    (1984); Consumer Prod. Safety Commn. v. GTE Sylvania, 
    447 U.S. 102
    , 117 (1980).    In the end, the courts alone must declare what
    the Canadian Convention and particularly Article VII mean.    See
    American Exch. Sec. Corp. v. Helvering, 
    74 F.2d 213
    , 214 (1934).
    In sum, we are confronted with a situation, in which the
    language of Article VII, paragraph (2) is at best murky, and the
    interpretations of both parties have advantages and
    disadvantages.     We are impressed that the Canadian Convention may
    give an economic advantage to Canadian insurance companies
    operating through a permanent establishment in the United States.
    Nevertheless, our view is that petitioner's interpretation of
    Article VII, paragraph (2) best carries out the intent of the
    20
    (...continued)
    regulatory authority for the Secretary to provide a relief
    mechanism to mitigate the effects of any increase in tax
    resulting from the fact that a taxpayer's deemed income from
    required U.S. assets exceeds its actual income from those assets.
    - 59 -
    United States and Canada as set forth in the Canadian Convention
    and satisfies the purpose of Article VII of the Canadian
    Convention--to attribute income to a permanent establishment
    based on its real facts, and, accordingly, we so hold.
    Having found that petitioner is entitled to relief from
    section 842(b) based on Article VII, paragraph (2) of the
    Canadian Convention, we have no need to delve into the question
    of whether petitioner is also entitled to such relief based on
    Article XXV, paragraph (6).
    Finally, we note that respondent did not contend that
    section 482 applied in the instant case.   Accordingly, our
    decision in the instant case does not consider the application of
    section 482 in those circumstances in which the Convention also
    applies.
    The Executive Branch with the advice and consent of the
    Senate has the option of negotiating a new protocol with Canada
    creating an exception similar to one included in subsequent
    conventions.   These conventions contain a general directive to
    determine profits as if the taxpayer was a separate entity yet
    also include explicit exceptions permitting each country to apply
    its own internal methods of taxation to the business profits of
    an insurance company's permanent establishment.   See, e.g., art.
    7(7), Tax Convention, U.S.-N.Z., 7/23/82, 35 U.S.T. (Part 2)
    - 60 -
    1949, 1990-2 C.B. 274.21   We have considered all of the other
    arguments made by respondent and, to the extent we have not
    addressed them, find them to be without merit.
    Decision will be entered
    for petitioner.

    HALPERN, J., concurring:     I concur in the result reached by
    the majority.    Like the majority, I believe that this case turns
    on an interpretation of Article VII of the United States-Canada
    Income Tax Convention, Sept. 26, 1980, T.I.A.S. No. 11087, 1986-2
    C.B. 258 (Canadian Convention).    Unlike the majority, I do not
    believe that this case turns on Article VII, paragraph 2
    (paragraph 2).   I believe that one need look no further than
    Article VII, paragraph 1 (paragraph 1), to conclude that
    petitioner prevails.
    Section 842(b) is inconsistent with paragraph 1.    The
    imputation to a foreign insurance company of a notional amount of
    investment income under section 842(b) (minimum ECNII), see
    majority op. part I, contravenes the threshold requirement in
    paragraph 1 that the business profits attributed to a permanent
    establishment come from the pool of business profits of the
    resident carrying on business through the permanent
    establishment.   Paragraph 1 provides:
    The business profits of a resident of a Contracting
    State shall be taxable only in that State unless the
    resident carries on business in the other Contracting
    State through a permanent establishment situated
    therein. If the resident carries on, or has carried
    on, business as aforesaid, the business profits of the
    resident may be taxed in the other State but only so
    much of them as is attributable to that permanent
    establishment. [Emphasis added.]
    The notion that there exists a pool of business profits of which
    the business profits of the permanent establishment are a subset
    - 62 -
    is derived from the pronoun in the phrase "only so much of them",
    which refers to the business profits of the resident carrying on
    business through the permanent establishment.    Although the
    precise meaning of the phrase "business profits of the resident"
    may be subject to debate, I believe that it does not include a
    notional amount of investment income derived from a formula based
    on the domestic asset/liability percentage and the domestic
    investment yield as provided in section 842(b).
    Minimum ECNII is not income of a type that is subject to
    attribution under paragraph 1, and, therefore, the issue as to
    whether the method of attribution under section 842(b) is
    consistent with the "separate-entity principle" embodied in
    paragraph 2 need not be addressed.    The majority, however,
    focuses its analysis on that particular issue and ultimately
    decides for petitioner on the basis that the methodology in
    section 842(b) is inconsistent with paragraph 2.    The majority
    states,
    we hold that the disposition of this case turns on
    whether the section 842(b)(1) formula prescribes a
    minimum amount of ECNII based on the facts as they
    relate to petitioner's permanent establishment, by
    reference to the establishment's separate accounts
    insofar as those accounts represent the facts of the
    situation * * *. [Majority op. p. 37.]
    The majority concludes, "We are convinced that section 842(b) is
    contrary to and inconsistent with Article VII, paragraph (2),
    - 63 -
    which precludes the fictional allocation of business profits to
    petitioner's permanent establishment."    Majority op. p. 39.
    I believe that the majority need not have considered
    paragraph 2.   Attribution of notional income is precluded not by
    paragraph 2, but, rather, by the restrictive language of
    paragraph 1 set forth above.    Paragraph 11 of the Commentary on
    Article VII of the Model Double Taxation Convention on Income and
    on Capital, Report of the O.E.C.D. Committee on Fiscal Affairs
    (1977) (Model Treaty), cited by the majority on page 44,
    provides, in part, "It should perhaps be emphasized that the
    directive contained in paragraph 2 is no justification for tax
    administrations to construct hypothetical profit figures in
    vacuo”.   (Emphasis added.)   It is noteworthy that Article VII,
    paragraph 2, of the Model Treaty, which is identical in relevant
    respect to the Canadian Convention, does not affirmatively
    restrict the use of hypothetical profit figures, but, rather,
    only provides no justification to employ fictional profit figures
    in calculating the income attributable to a permanent
    establishment.   It seems unlikely that paragraph 2 could restrict
    the use of hypothetical profit figures as the majority opines and
    simultaneously provide a potential justification to use such
    figures that is sufficiently colorable to require an explicit
    O.E.C.D. commentary advising against the practice.    Accordingly,
    I cannot join the reasoning of the majority.
    WHALEN, J., agrees with this concurring opinion.
    - 64 -
    RUWE, J., dissenting:   Section 842(b) was enacted to prevent
    foreign insurance companies operating permanent business
    establishments in the United States from being able to shift
    profits on investments out of the U.S. taxing jurisdiction.
    Section 842(b) does this by attributing a minimum amount of
    income to the permanent U.S. business establishment.   This
    minimum amount of U.S. income is computed by a statutory formula
    that essentially uses the investment experience of comparable
    domestic insurance companies and applies that data to the U.S.
    branch of the foreign company, based on the actual insurance
    coverage liabilities incurred by the U.S. branch as a result of
    insurance sold by its U.S. business.   This provision was to serve
    as a backstop in recognition that assets and liabilities can be
    moved between the U.S. business and the foreign corporation,
    resulting in the reduction of U.S. tax.
    The parties agree that section 842(b) applies, unless it is
    trumped by provisions of the Treaty between the United States and
    Canada.   Convention with Respect to Taxes on Income and on
    Capital, Sept. 26, 1980, U.S.-Can., T.I.A.S. No. 11087.
    Respondent argues that section 842(b) is a permissible method of
    attributing profits to a permanent establishment within the terms
    of the Treaty.   Petitioner contends that article VII, paragraph
    (2) of the Treaty requires the income of a permanent
    establishment to be measured by its own specific operations as
    reflected in its books and precludes taxing Canadian companies on
    - 65 -
    amounts greater than the actual income derived from their
    business in the United States.    The majority agrees with
    petitioner that article VII, paragraph (2) precludes the
    allocation of business profits to petitioner's permanent U.S.
    establishment that is in excess of its actual income as reported
    in its records.   I disagree.
    Article VII, paragraph (2) of the Canadian Treaty provides:
    2. Subject to the provisions of paragraph 3, where a
    resident of a Contracting State carries on business in
    the other Contracting State through a permanent
    establishment situated therein, there shall in each
    Contracting State be attributed to that permanent
    establishment the business profits which it might be
    expected to make if it were a distinct and separate
    person engaged in the same or similar activities under
    the same or similar conditions and dealing wholly
    independently with the resident and with any other
    person related to the resident * * * [Emphasis added.]
    This provision of the Canadian Treaty does not restrict U.S.
    taxation of profits of a foreign corporation's permanent
    establishment to amounts actually earned by the U.S. business as
    reflected in its records.   Article VII, paragraph (1) of the
    Treaty provides that if a Canadian corporation carries on
    business in the United States through a permanent establishment,
    the United States may tax its profits, "but only so much of them
    as is attributable to that permanent establishment."    (Emphasis
    added.)   Article VII, paragraph (2) provides that the amount to
    "be attributed to that permanent establishment" is "the business
    profits which it might be expected to make if it were a distinct
    - 66 -
    and separate person" dealing wholly independently with the
    foreign entity.   (Emphasis added.)
    Use of the words "attributable" and "attributed" connote
    going beyond the actual profits earned and reported by the
    permanent establishment.   Attribute means "To assign to a cause
    or source".   Webster's II New Riverside University Dictionary 137
    (1984).   For example, the "attribution" rules of section 267(c)
    assign ownership of stock to persons other than the actual
    owners.   The profits to be attributed are those "which it [U.S.
    business] might be expected to make if" it were a separate person
    engaged in the same or similar activities and dealing
    independently.    The words "might be expected to make" obviously
    mean something other than "actually made".   "Might" means a
    "condition or state contrary to fact", Webster's II New Riverside
    University Dictionary 751 (1984); "expected" means something that
    probably could or would have been; and the word "if" refers to
    conditions other than those that actually occurred (i.e., if the
    U.S. business were a distinct and separate person dealing
    independently).   Thus, the Treaty must be read in a manner that
    allows the attribution of profits to the U.S. business
    establishment in an amount that is at variance with the actual
    profits reported by the U.S. business.   Any other interpretation
    makes the aforementioned Treaty provisions redundant.
    The Model Commentaries to article VII, paragraph (2) support
    this interpretation.   They provide:
    - 67 -
    10. This paragraph contains the central directive on
    which the allocation of profits to a permanent
    establishment is intended to be based. The paragraph
    incorporates the view, which is generally contained in
    bilateral conventions, that the profits to be
    attributed to a permanent establishment are those which
    that permanent establishment would have made if,
    instead of dealing with its head office, it had been
    dealing with an entirely separate enterprise under
    conditions and at prices prevailing in the ordinary
    market. Normally, these would be the same profits that
    one would expect to be determined by the ordinary
    processes of good business accountancy. * * *
    [Emphasis added.]
    13. Clearly many special problems of this kind may
    arise in individual cases but the general rule should
    always be that the profits attributed to a permanent
    establishment should be based on that establishment’s
    accounts insofar as accounts are available which
    represent the real facts of the situation. * * *.
    [Model Commentaries to Article 7, paragraph (2) of the
    Model Treaty; emphasis added.]
    The Commentaries speak of "allocation" of profits.
    Allocations are generally understood to include adjustments to
    what was actually done and reported.   See, for example, the
    authority to "allocate" income between related parties under
    section 482.   The Commentaries eliminate any doubt that the term
    "allocation" is used in this sense when it says that the profits
    to be "allocated" or "attributed" are profits which "would have
    [been] made if, instead of dealing with its head office, it [the
    U.S. establishment] had been dealing with an entirely separate
    enterprise".   (Emphasis added.)   "Would have", "if", "instead
    of", and "it had been", clearly refer to an allocation and
    - 68 -
    attribution of profits based on a hypothetical situation
    different from the facts that actually occurred.
    Paragraph 13 of the above-quoted Commentaries does not
    contradict paragraph 10.   It simply states that profits
    "attributed" should be based on the establishment's accounts to
    the extent they represent real facts.    The profits "allocated"
    and "attributed" pursuant to section 842(b) are based on the real
    facts regarding the amount of insurance coverage sold by
    petitioner's U.S. insurance business.    The volume of petitioner's
    U.S. business is reflected by its actual liabilities on policies
    issued by the U.S. branch.   The amount of assets that would have
    been expected to be held by a separate U.S. entity with those
    actual liabilities and the expected profits on the assets of such
    a separate entity are hypothetical.    However, to require total
    acceptance of all figures reported in petitioner's records
    reflecting its profits on U.S. operations carried out as a branch
    of a foreign corporation would not only nullify section 842(b)
    but also nullify the allocation procedure specifically permitted
    in article VII, paragraph (2).1
    1
    Sec. 842(b) does not contravene the admonition in par. 11
    of the Model Commentary that tax administrators should not
    "construct hypothetical profit figures in vacuo." Sec. 842(b)
    starts with the taxpayer's real facts regarding the amount of
    insurance liabilities it incurred selling insurance in the United
    States and then makes adjustments based on comparable domestic
    companies.

    The contemporaneous Technical Explanation of the Treaty
    prepared by the Treasury Department and submitted to the Senate
    Foreign Relations Committee for its consideration prior to
    ratification is consistent with my interpretation of the Treaty.
    The Technical Explanation states in pertinent part:
    Paragraph 7 provides a definition for the term
    "attributable to." Profits "attributable to" a
    permanent establishment are those derived from the
    assets or activities of the permanent establishment.
    Paragraph 7 does not preclude Canada or the United
    States from using appropriate domestic tax law rules of
    attribution. * * * [U.S. Dept. of the Treasury,
    Technical Explanation of Convention With Respect to
    Taxes on Income and on Capital, Sept. 26, 1980, U.S.-
    Can., as amended, at 13 (Apr. 26, 1995) (emphasis
    added.)2]
    Provisions substantially similar to section 842(b) were
    already in the Code at the time the Canadian Treaty was signed
    and ratified.
    Under the regime of section 813, which was in effect in 1984
    when the Treaty was ratified and became effective, a foreign life
    insurance company's income that was effectively connected with

    The majority narrowly reads the Technical Explanation's use
    of domestic tax law rules of attribution as being limited to
    paragraph 7 of article VII of the Treaty. See majority op. p.
    36. However, paragraph 7 of article VII of the Treaty itself
    applies to the entire Convention:
    7. For the purposes of the Convention, the business
    profits attributable to a permanent establishment shall
    include only those profits derived from the assets or
    activities of the permanent establishment. [Emphasis
    added.]
    - 70 -
    the conduct of a U.S. insurance business was increased by an
    imputed amount if its surplus held in the United States was less
    than a statutorily defined required surplus.     Sec. 813(a)(1).
    The minimum surplus was computed in the same manner as prior
    section 819(a)(2), which was in effect in 1980 when the Treaty
    was signed.    Sec. 813(a)(2).   Under section 819, a foreign life
    insurance company was required to reduce certain deductions by an
    imputed amount if its surplus fell below a statutorily defined
    amount.   Sec. 819(a)(2).   The required surplus was computed by
    multiplying the company's total insurance liabilities on U.S.
    business by the ratio of the surplus to total insurance
    liabilities of domestic life insurance companies.     Sec.
    819(a)(2).
    Similarly, section 842(b) imputes to the U.S. branch a
    minimum amount of assets based upon the branch's actual
    liabilities.   This minimum amount is determined by multiplying
    the U.S. branch's own liabilities by the applicable
    asset/liability ratio.   Sec. 842(b)(2)(A).    Resembling sections
    819(a)(2) and 813(a)(2), section 842(b) uses asset and liability
    figures from domestic life insurance companies in order to
    calculate this applicable ratio.     Sec. 842(b)(2)(C).   Therefore,
    the rule in section 842(b)(2), which imputes an amount of
    "required U.S. assets" is merely a continuation of a principle
    that has been consistently applied for over 35 years.
    - 71 -
    In addition, the calculation of the investment yield under
    section 842(b)(4) is substantially similar to the computation
    under prior section 819(a).   The earnings rate of section
    819(a)(1)(B) was determined by dividing the investment yield for
    the entire company (not just the U.S. branch) by the mean of all
    the company's assets.3   The election available to taxpayers under
    section 842(b)(4) also calculates investment yield using the
    company's own worldwide figures.4   Section 842(b)(4) calculates
    the company's worldwide investment yield by dividing the net
    investment income of the company from all sources by the mean of
    all the company's assets.   Therefore, section 842(b) is
    substantially similar to the historic approach in both the manner
    in which assets are imputed and the calculation of investment
    yield.
    Three years after the effective date of the Treaty, Congress
    enacted section 842(b) to replace section 813.   The conference
    report regarding enactment of section 842(b) indicates that the
    Treasury Department and Congress carefully considered existing
    3
    The current earnings rate for sec. 819(a)(1)(B) was defined
    in sec. 805(b)(2).

    As explained in the House committee report, "The committee
    adopted the worldwide yield alternative to avoid discriminating
    against foreign companies whose investment performance does not
    attain the U.S. average." H. Rept. 100-391 (Part 2), at 1110
    (1987). If the taxpayer does not make this election to use its
    own investment yield, sec. 842(b)(3) requires use of the
    investment yield of domestic insurance companies.
    - 72 -
    treaties and concluded that section 842(b) was consistent with
    existing treaties, including the Canadian Treaty.
    The conference report on section 842(b) states:
    In particular, the Treasury Department believes that
    the provision does not violate treaty requirements that
    foreign corporations be taxed only on profits derived
    from the assets or activities of a corporation's U.S.
    permanent establishment, that permanent establishments
    of foreign corporations be taxed only on profits the
    permanent establishments might be expected to make were
    they separate enterprises dealing independently with
    the foreign corporations of which they are a part, or
    that permanent establishments of foreign corporations
    be taxed in a manner no more burdensome than the manner
    in which domestic corporations in the same
    circumstances are taxed. The conferees similarly
    believe that this provision does not violate any treaty
    now in effect.
    Several factors are cited by the Treasury
    Department in support of this view. First, the
    provision applies to life insurance companies and
    property and casualty insurance companies in a manner
    substantially similar to present-law rules covering
    only life insurance companies. The Treasury Department
    does not consider those present-law rules to violate
    U.S. treaties.
    Second, the provision attributes to a foreign
    insurance company an amount of assets determined by
    reference to the assets of comparable domestic
    insurance companies, thus reasonably measuring the
    amount of assets that the U.S. trade or business of a
    foreign insurance company would be expected to have
    were it a separate company dealing independently with
    non-U.S. offices of the foreign insurance company. In
    addition, a foreign insurance company can elect to
    determine its investment income based on the company's
    worldwide investment yield, or utilize the statutory
    formula based on domestic industry averages. It is
    well established that use of a formula as an element in
    determining taxable income does not necessarily violate
    "separate entity" accounting. The Internal Revenue
    Code contains a number of provisions that apply
    fungibility principles to financial assets; use of
    - 73 -
    fungibility principles in these ways is not
    inconsistent with the arm's-length standard and does
    not violate U.S. income tax treaties. Similarly, the
    agreement's provision, which takes into account both
    the taxpayer's actual investment yield and arm's-length
    measures of yield and U.S.-connected assets, is
    appropriate under income tax treaties. [H. Conf. Rept.
    100-495, at 983-984 (1987), 1987-3 C.B. 193, 263-264;
    emphasis added.]
    The majority correctly states that we must consider the
    expectation and intentions of the signatories to a Treaty.     I
    believe that the plain language of the Treaty and Commentaries
    supports respondent's position that section 842(b) is consistent
    with the Treaty.   Clearly, the Treasury Department's
    preratification explanation of the Treaty, the statutory
    provisions in place when the Treaty was signed and ratified, the
    consistent interpretation of the Treaty provisions by the United
    States Government, and the express view of Congress shortly after
    ratification that section 842(b) was consistent with the Treaty,
    all support the conclusion that the United States intended and
    believed that the Treaty and section 842(b) were consistent.       The
    majority cites to no contrary statements of intent made by the
    Canadian Government during the 15 years between signing the
    Treaty and this litigation.   Applying settled principles of
    interpretation to the situation before us, it is clear that the
    language of the Treaty contemplates the attribution of profits
    beyond the actual profits that were earned or reported.    Section
    - 74 -
    842(b) accomplishes this in a rational manner using substantially
    the same methodology that has been in the Code for over 35 years.
    The majority also finds that section 842(b) is not
    consistent with article VII, paragraph (5) of the Treaty.    This
    provision of the Treaty requires that the same method be used to
    attribute business profits in each year, unless there is good and
    sufficient reason to the contrary.     The Model Commentary to this
    provision explains that its purpose is to assure an enterprise
    with a permanent establishment in another state, continuous and
    consistent tax treatment in the interest of providing some degree
    of certainty.   Section 842(b), as did its predecessors, applies
    consistently to each taxable period by requiring foreign
    insurance companies to report at least a minimum amount of
    effectively connected net investment income.
    Finally, it has been suggested that the minimum effectively
    connected income formula of section 842(b) "creates" income even
    if the foreign company has earned no overall profit during a
    given taxable year.   It is argued that this could go beyond the
    "allocation" of the foreign company's profits permitted by
    article VII, paragraph 1 of the Treaty.    This was clearly not the
    purpose of section 842(b).   As stated in the conference report,
    H. Conf. Rept. 
    100-495, supra
    , 1987-3 C.B. at 264, Congress
    intended that the Secretary issue regulations "to mitigate the
    effects of any increase in tax resulting from the fact that a
    taxpayer's deemed income from U.S.-connected investments exceeds
    - 75 -
    its actual income from those assets."    In Notice 89-96, 1989-2
    C.B. 417, 420, which was issued as interim guidance until
    regulations are published, the Commissioner provides that "a
    foreign insurance company's minimum effectively connected net
    investment income includible in taxable income for the taxable
    year shall not exceed its worldwide gross investment income for
    the taxable year".    Petitioner does not allege that it comes
    within this provision.
    The ramifications of the majority opinion go well beyond the
    resolution of this case.    The provisions of the Canadian Treaty
    are based on Model Treaty Provisions used in many other treaties.
    In essence, the majority nullifies section 842(b).    This raises
    the distinct possibility that foreign insurance companies with
    operations in the United States will have an advantage over
    domestic companies.    Such a result is clearly contrary to the
    Internal Revenue Code and article VII, paragraph (2) of the
    Treaty.5   Moreover, the majority's interpretation of article VII,
    paragraph (2) raises serious questions about the use of other
    statutory methods of allocating the income and expenses of
    foreign persons that operate businesses in the United States
    5
    Sec. 842(b) puts foreign insurance companies in the same
    situation, taxwise, as comparable domestic companies. It does
    not discriminate against foreign companies. On the other hand,
    the majority acknowledges that its interpretation of the Treaty
    invalidating sec. 842(b) may give Canadian insurance companies,
    operating a permanent establishment in the United States, an
    economic advantage over U.S. companies. See majority op. p. 55.
    - 76 -
    where such allocations are premised on the use of comparables to
    determine what "might have" or "would have" occurred "if"
    conditions or events were different from those that actually
    occurred.
    SWIFT, COLVIN, FOLEY, and GALE, JJ., agree with this
    dissent.
