    Sec. 404. Deduction for contributions of an employer to an
        employees' trust or annuity plan and compensation under a
        deferred-payment plan
 
    (a) General rule
      If contributions are paid by an employer to or under a stock
    bonus, pension, profit-sharing, or annuity plan, or if compensation
    is paid or accrued on account of any employee under a plan
    deferring the receipt of such compensation, such contributions or
    compensation shall not be deductible under this chapter; but, if
    they would otherwise be deductible, they shall be deductible under
    this section, subject, however, to the following limitations as to
    the amounts deductible in any year:
      (1) Pension trusts
        (A) In general
          In the taxable year when paid, if the contributions are paid
        into a pension trust (other than a trust to which paragraph (3)
        applies), and if such taxable year ends within or with a
        taxable year of the trust for which the trust is exempt under
        section 501(a) in the case of a defined benefit plan other 
        than a multiemployer plan, in an amount determined under 
        subsection (o), and in the case of any 
        other plan, in an amount determined as follows:
            (i) the amount necessary to satisfy the minimum funding
          standard provided by section 412(a) for plan years ending
          within or with such taxable year (or for any prior plan
          year), if such amount is greater than the amount determined
          under clause (ii) or (iii) (whichever is applicable with
          respect to the plan),
            (ii) the amount necessary to provide with respect to all of
          the employees under the trust the remaining unfunded cost of
          their past and current service credits distributed as a level
          amount, or a level percentage of compensation, over the
          remaining future service of each such employee, as determined
          under regulations prescribed by the Secretary, but if such
          remaining unfunded cost with respect to any 3 individuals is
          more than 50 percent of such remaining unfunded cost, the
          amount of such unfunded cost attributable to such individuals
          shall be distributed over a period of at least 5 taxable
          years,
            (iii) an amount equal to the normal cost of the plan, as
          determined under regulations prescribed by the Secretary,
          plus, if past service or other supplementary pension or
          annuity credits are provided by the plan, an amount necessary
          to amortize the unfunded costs attributable to such credits
          in equal annual payments (until fully amortized) over 10
          years, as determined under regulations prescribed by the
          Secretary.
        In determining the amount deductible in such year under the
        foregoing limitations the funding method and the actuarial
        assumptions used shall be those used for such year under
        section 431, and the maximum amount deductible for such year
        shall be an amount equal to the full funding limitation for
        such year determined under section 431.
        (B) Special rule in case of certain amendments
          In the case of a multiemployer plan which the Secretary of Labor 
        finds to be collectively bargained which makes an election under this
        subparagraph (in such manner and at such time as may be
        provided under regulations prescribed by the Secretary), if the
        full funding limitation determined under section 431(c)(6) for
        such year is zero, if as a result of any plan amendment
        applying to such plan year, the amount determined under section
        431(c)(6)(A)(ii) exceeds the amount determined under section
        431(c)(6)(A)(i), and if the funding method and the actuarial
        assumptions used are those used for such year under section
        431, the maximum amount deductible in such year under the
        limitations of this paragraph shall be an amount equal to the
        lesser of -
            (i) the full funding limitation for such year determined by
          applying section 412(c)(7) but increasing the amount referred
          to in subparagraph (A) thereof by the decrease in the present
          value of all unamortized liabilities resulting from such
          amendment, or
            (ii) the normal cost under the plan reduced by the amount
          necessary to amortize in equal annual installments over 10
          years (until fully amortized) the decrease described in
          clause (i).
        In the case of any election under this subparagraph, the amount
        deductible under the limitations of this paragraph with respect
        to any of the plan years following the plan year for which such
        election was made shall be determined as provided under such
        regulations as may be prescribed by the Secretary to carry out
        the purposes of this subparagraph.
        (C) Certain collectively-bargained plans
          In the case of a plan which the Secretary of Labor finds to
        be collectively bargained, established or maintained by an
        employer doing business in not less than 40 States and engaged
        in the trade or business of furnishing or selling services
        described in section 168(i)(10)(C), with respect to which the
        rates have been established or approved by a State or political
        subdivision thereof, by any agency or instrumentality of the
        United States, or by a public service or public utility
        commission or other similar body of any State or political
        subdivision thereof, and in the case of any employer which is a
        member of a controlled group with such employer, subparagraph
        (B) shall be applied by substituting for the words ''plan
        amendment'' the words ''plan amendment or increase in benefits
        payable under title II of the Social Security Act''. For the
        purposes of this subparagraph, the term ''controlled group''
        has the meaning provided by section 1563(a), determined without
        regard to section 1563(a)(4) and (e)(3)(C).
        (D) Amount determined on basis of unfunded current 
          liability.--In the case of a defined benefit plan which 
          is a multiemployer plan, except as provided in 
          regulations, the maximum amount deductible under the 
          limitations of this paragraph shall not be less than the 
          excess (if any) of--
            (i) 140 percent of the current liability of 
          the plan determined under section 431(c)(6)(C), over
            (ii) the value of the plan's assets 
          determined under section 431(c)(2).
        (E) Carryover
          Any amount paid in a taxable year in excess of the amount
          deductible in such year under the foregoing limitations shall
          be deductible in the succeeding taxable years in order of time
          to the extent of the difference between the amount paid and
          deductible in each such succeeding year and the maximum amount
          deductible for such year under the foregoing limitations.
      (2) Employees' annuities
        In the taxable year when paid, in an amount determined in
      accordance with paragraph (1), if the contributions are paid
      toward the purchase of retirement annuities, or retirement
      annuities and medical benefits as described in section 401(h),
      and such purchase is part of a plan which meets the requirements
      of section 401(a)(3), (4), (5), (6), (7), (8), (9), (11), (12),
      (13), (14), (15), (16), (17), (FOOTNOTE 1) (19), (20), (22),
      (26), (27), and (31) and, if applicable, the requirements of
      section 401(a)(10) and of section 401(d), and if refunds of
      premiums, if any, are applied within the current taxable year or
      next succeeding taxable year toward the purchase of such
      retirement annuities, or such retirement annuities and medical
      benefits.
       (FOOTNOTE 1) See References in Text note below.
      (3) Stock bonus and profit-sharing trusts
        (A) Limits on deductible contributions
          (i) In general
            In the taxable year when paid, if the contributions are
          paid into a stock bonus or profit-sharing trust, and if such
          taxable year ends within or with a taxable year of the trust
          with respect to which the trust is exempt under section
          501(a), in an amount not in excess of the greater of -
              (I) 25 percent of the compensation otherwise paid or
            accrued during the taxable year to the beneficiaries under
            the stock bonus or profit-sharing plan, or
              (II) the amount such employer is required to contribute
            to such trust under section 401(k)(11) for such year.
          (ii) Carryover of excess contributions
            Any amount paid into the trust in any taxable year in
          excess of the limitation of clause (i) (or the corresponding
          provision of prior law) shall be deductible in the succeeding
          taxable years in order of time, but the amount so deductible
          under this clause in any 1 such succeeding taxable year
          together with the amount allowable under clause (i) shall not
          exceed the amount described in subclause (I) or (II) of
          clause (i), whichever is greater, with respect to such
          taxable year.
          (iii) Certain retirement plans excluded
            For purposes of this subparagraph, the term ''stock bonus
          or profit-sharing trust'' shall not include any trust
          designed to provide benefits upon retirement and covering a
          period of years, if under the plan the amounts to be
          contributed by the employer can be determined actuarially as
          provided in paragraph (1).
          (iv) 2 or more trusts treated as 1 trust
            If the contributions are made to 2 or more stock bonus or
          profit-sharing trusts, such trusts shall be considered a
          single trust for purposes of applying the limitations in this
          subparagraph.
          (v) Defined contribution plans subject to the funding
              standards
            Except as provided by the Secretary, a defined contribution
          plan which is subject to the funding standards of section 412
          shall be treated in the same manner as a stock bonus or
          profit-sharing plan for purposes of this subparagraph.
        (B) Profit-sharing plan of affiliated group
          In the case of a profit-sharing plan, or a stock bonus plan
        in which contributions are determined with reference to
        profits, of a group of corporations which is an affiliated
        group within the meaning of section 1504, if any member of such
        affiliated group is prevented from making a contribution which
        it would otherwise have made under the plan, by reason of
        having no current or accumulated earnings or profits or because
        such earnings or profits are less than the contributions which
        it would otherwise have made, then so much of the contribution
        which such member was so prevented from making may be made, for
        the benefit of the employees of such member, by the other
        members of the group, to the extent of current or accumulated
        earnings or profits, except that such contribution by each such
        other member shall be limited, where the group does not file a
        consolidated return, to that proportion of its total current
        and accumulated earnings or profits remaining after adjustment
        for its contribution deductible without regard to this
        subparagraph which the total prevented contribution bears to
        the total current and accumulated earnings or profits of all
        the members of the group remaining after adjustment for all
        contributions deductible without regard to this subparagraph.
        Contributions made under the preceding sentence shall be
        deductible under subparagraph (A) of this paragraph by the
        employer making such contribution, and, for the purpose of
        determining amounts which may be carried forward and deducted
        under the second sentence of subparagraph (A) of this paragraph
        in succeeding taxable years, shall be deemed to have been made
        by the employer on behalf of whose employees such contributions
        were made.
      (4) Trusts created or organized outside the United States
        If a stock bonus, pension, or profit-sharing trust would
      qualify for exemption under section 501(a) except for the fact
      that it is a trust created or organized outside the United
      States, contributions to such a trust by an employer which is a
      resident, or corporation, or other entity of the United States,
      shall be deductible under the preceding paragraphs.
      (5) Other plans
        If the plan is not one included in paragraph (1), (2), or (3),
      in the taxable year in which an amount attributable to the
      contribution is includible in the gross income of employees
      participating in the plan, but, in the case of a plan in which
      more than one employee participates only if separate accounts are
      maintained for each employee.  For purposes of this section, any
      vacation pay which is treated as deferred compensation shall be
      deductible for the taxable year of the employer in which paid to
      the employee.
      (6) Time when contributions deemed made
        For purposes of paragraphs (1), (2), and (3), a taxpayer shall
      be deemed to have made a payment on the last day of the preceding
      taxable year if the payment is on account of such taxable year
      and is made not later than the time prescribed by law for filing
      the return for such taxable year (including extensions thereof).
      (7) Limitation on deductions where combination of defined
          contribution plan and defined benefit plan
        (A) In general
          If amounts are deductible under the foregoing paragraphs of
        this subsection (other than paragraph (5)) in connection with 1
        or more defined contribution plans and 1 or more defined
        benefit plans or in connection with trusts or plans described
        in 2 or more of such paragraphs, the total amount deductible in
        a taxable year under such plans shall not exceed the greater of
        -
            (i) 25 percent of the compensation otherwise paid or
          accrued during the taxable year to the beneficiaries under
          such plans, or
            (ii) the amount of contributions made to or under the
          defined benefit plans to the extent such contributions do not
          exceed the amount of employer contributions necessary to
          satisfy the minimum funding standard provided by section 412
          with respect to any such defined benefit plans for the plan
          year which ends with or within such taxable year (or for any
          prior plan year).
        A defined contribution plan which is a pension plan shall not
        be treated as failing to provide definitely determinable
        benefits merely by limiting employer contributions to amounts
        deductible under this section.  For purposes of clause (ii), if
        paragraph (1)(D) applies to a defined benefit plan for any plan
        year, the amount necessary to satisfy the minimum funding
        standard provided by section 412 with respect to such plan for
        such plan year shall not be less than the unfunded current
        liability of such plan under section 412(l).
        In the case of a defined benefit plan which is a single employer plan, 
        the amount necessary to satisfy the minimum funding standard 
        provided by section 412 shall not be less than the 
        plan's funding shortfall determined under section 430.
        (B) Carryover of contributions in excess of the deductible
            limit
          Any amount paid under the plans in any taxable year in excess
        of the limitation of subparagraph (A) shall be deductible in
        the succeeding taxable years in order of time, but the amount
        so deductible under this subparagraph in any 1 such succeeding
        taxable year together with the amount allowable under
        subparagraph (A) shall not exceed 25 percent of the
        compensation otherwise paid or accrued during such taxable year
        to the beneficiaries under the plans.
        (C) Paragraph not to apply in certain cases.--
            (i) Beneficiary test.--This paragraph shall 
              not have the effect of reducing the amount 
              otherwise deductible under paragraphs (1), (2), 
              and (3), if no employee is a beneficiary under more than 
              1 trust or under a trust and an annuity plan.
            (ii) Elective deferrals.--If, in connection 
              with 1 or more defined contribution plans and 1 or 
              more defined benefit plans, no amounts (other than 
              elective deferrals (as defined in section 
              402(g)(3))) are contributed to any of the defined 
              contribution plans for the taxable year, then 
              subparagraph (A) shall not apply with respect to 
              any of such defined contribution plans and defined 
              benefit plans.
            (iii) Limitation.--In the case of employer 
              contributions to 1 or more defined contribution 
              plans, this paragraph shall only apply to the 
              extent that such contributions exceed 6 percent of 
              the compensation otherwise paid or accrued during 
              the taxable year to the beneficiaries under such 
              plans. For purposes of this clause, amounts 
              carried over from preceding taxable years under 
              subparagraph (B) shall be treated as employer 
              contributions to 1 or more defined contributions 
              to the extent attributable to employer 
              contributions to such plans in such preceding 
              taxable years.
            (iv) Guaranteed plans.--In applying this 
              paragraph, any single-employer plan covered under 
              section 4021 of the Employee Retirement Income 
              Security Act of 1974 shall not be taken into 
              account.
            (v) Multiemployer plans.--In applying this 
              paragraph, any multiemployer plan shall not be 
              taken into account.
          (D) Insurance contract plans.--For purposes of 
                this paragraph, a plan described in section 412(e)(3) 
                shall be treated as a defined benefit plan.
       (8) Self-employed individuals
        In the case of a plan included in paragraph (1), (2), or (3)
      which provides contributions or benefits for employees some or
      all of whom are employees within the meaning of section
      401(c)(1), for purposes of this section -
          (A) the term ''employee'' includes an individual who is an
        employee within the meaning of section 401(c)(1), and the
        employer of such individual is the person treated as his
        employer under section 401(c)(4);
          (B) the term ''earned income'' has the meaning assigned to it
        by section 401(c)(2);
          (C) the contributions to such plan on behalf of an individual
        who is an employee within the meaning of section 401(c)(1)
        shall be considered to satisfy the conditions of section 162 or
        212 to the extent that such contributions do not exceed the
        earned income of such individual (determined without regard to
        the deductions allowed by this section) derived from the trade
        or business with respect to which such plan is established, and
        to the extent that such contributions are not allocable
        (determined in accordance with regulations prescribed by the
        Secretary) to the purchase of life, accident, health, or other
        insurance; and
          (D) any reference to compensation shall, in the case of an
        individual who is an employee within the meaning of section
        401(c)(1), be considered to be a reference to the earned income
        of such individual derived from the trade or business with
        respect to which the plan is established.
      (9) Certain contributions to employee stock ownership plans
        (A) Principal payments
          Notwithstanding the provisions of paragraphs (3) and (7), if
        contributions are paid into a trust which forms a part of an
        employee stock ownership plan (as described in section
        4975(e)(7)), and such contributions are, on or before the time
        prescribed in paragraph (6), applied by the plan to the
        repayment of the principal of a loan incurred for the purpose
        of acquiring qualifying employer securities (as described in
        section 4975(e)(8)), such contributions shall be deductible
        under this paragraph for the taxable year determined under
        paragraph (6). The amount deductible under this paragraph shall
        not, however, exceed 25 percent of the compensation otherwise
        paid or accrued during the taxable year to the employees under
        such employee stock ownership plan.  Any amount paid into such
        trust in any taxable year in excess of the amount deductible
        under this paragraph shall be deductible in the succeeding
        taxable years in order of time to the extent of the difference
        between the amount paid and deductible in each such succeeding
        year and the maximum amount deductible for such year under the
        preceding sentence.
        (B) Interest payment
          Notwithstanding the provisions of paragraphs (3) and (7), if
        contributions are made to an employee stock ownership plan
        (described in subparagraph (A)) and such contributions are
        applied by the plan to the repayment of interest on a loan
        incurred for the purpose of acquiring qualifying employer
        securities (as described in subparagraph (A)), such
        contributions shall be deductible for the taxable year with
        respect to which such contributions are made as determined
        under paragraph (6).
        (C) S corporations
          This paragraph shall not apply to an S corporation.
        (D) Qualified gratuitous transfers
          A qualified gratuitous transfer (as defined in section
        664(g)(1)) shall have no effect on the amount or amounts
        otherwise deductible under paragraph (3) or (7) or under this
        paragraph.
      (10) Contributions by certain ministers to retirement income
          accounts
        In the case of contributions made by a minister described in
      section 414(e)(5) to a retirement income account described in
      section 403(b)(9) and not by a person other than such minister,
      such contributions -
          (A) shall be treated as made to a trust which is exempt from
        tax under section 501(a) and which is part of a plan which is
        described in section 401(a), and
          (B) shall be deductible under this subsection to the extent
        such contributions do not exceed the limit on elective
        deferrals under section 402(g) or the limit on annual additions
        under section 415.
      For purposes of this paragraph, all plans in which the minister
      is a participant shall be treated as one plan.
      (11) Determinations relating to deferred compensation
        For purposes of determining under this section -
          (A) whether compensation of an employee is deferred
        compensation; and
          (B) when deferred compensation is paid,
      no amount shall be treated as received by the employee, or paid,
      until it is actually received by the employee.
      (12) Definition of compensation
        For purposes of paragraphs (3), (7), (8), and (9) and subsection (h)(1)(C), 
      the term ''compensation'' shall include amounts treated as ''participant's
      compensation'' under subparagraph (C) or (D) of section 415(c)(3).
    (b) Method of contributions, etc., having the effect of a plan;
        certain deferred benefits
      (1) Method of contributions, etc., having the effect of a plan
        If -
          (A) there is no plan, but
          (B) there is a method or arrangement of employer
        contributions or compensation which has the effect of a stock
        bonus, pension, profit-sharing, or annuity plan, or other plan
        deferring the receipt of compensation (including a plan
        described in paragraph (2)),
      subsection (a) shall apply as if there were such a plan.
      (2) Plans providing certain deferred benefits
        (A) In general
          For purposes of this section, any plan providing for deferred
        benefits (other than compensation) for employees, their
        spouses, or their dependents shall be treated as a plan
        deferring the receipt of compensation.  In the case of such a
        plan, for purposes of this section, the determination of when
        an amount is includible in gross income shall be made without
        regard to any provisions of this chapter excluding such
        benefits from gross income.
        (B) Exception
          Subparagraph (A) shall not apply to any benefit provided
        through a welfare benefit fund (as defined in section 419(e)).
    (c) Certain negotiated plans
      If contributions are paid by an employer -
        (1) under a plan under which such contributions are held in
      trust for the purpose of paying (either from principal or income
      or both) for the benefit of employees and their families and
      dependents at least medical or hospital care, or pensions on
      retirement or death of employees; and
        (2) such plan was established prior to January 1, 1954, as a
      result of an agreement between employee representatives and the
      Government of the United States during a period of Government
      operation, under seizure powers, of a major part of the
      productive facilities of the industry in which such employer is
      engaged,
    such contributions shall not be deductible under this section nor
    be made nondeductible by this section, but the deductibility
    thereof shall be governed solely by section 162 (relating to trade
    or business expenses).  For purposes of this chapter and subtitle
    B, in the case of any individual who before July 1, 1974, was a
    participant in a plan described in the preceding sentence -
        (A) such individual, if he is or was an employee within the
      meaning of section 401(c)(1), shall be treated (with respect to
      service covered by the plan) as being an employee other than an
      employee within the meaning of section 401(c)(1) and as being an
      employee of a participating employer under the plan,
        (B) earnings derived from service covered by the plan shall be
      treated as not being earned income within the meaning of section
      401(c)(2), and
        (C) such individual shall be treated as an employee of a
      participating employer under the plan with respect to service
      before July 1, 1975, covered by the plan.
    Section 277 (relating to deductions incurred by certain membership
    organizations in transactions with members) does not apply to any
    trust described in this subsection.  The first and third sentences
    of this subsection shall have no application with respect to
    amounts contributed to a trust on or after any date on which such
    trust is qualified for exemption from tax under section 501(a).
    (d) Deductibility of payments of deferred compensation, etc., to
        independent contractors
      If a plan would be described in so much of subsection (a) as
    precedes paragraph (1) thereof (as modified by subsection (b)) but
    for the fact that there is no employer-employee relationship, the
    contributions or compensation -
        (1) shall not be deductible by the payor thereof under this
      chapter, but
        (2) shall (if they would be deductible under this chapter but
      for paragraph (1)) be deductible under this subsection for the
      taxable year in which an amount attributable to the contribution
      or compensation is includible in the gross income of the persons
      participating in the plan.
    (e) Contributions allocable to life insurance protection for
        self-employed individuals
      In the case of a self-employed individual described in section
    401(c)(1), contributions which are allocable (determined under
    regulations prescribed by the Secretary) to the purchase of life,
    accident, health, or other insurance shall not be taken into
    account under paragraph (1), (2), or (3) of subsection (a).

      (1) In general
        For purposes of this section, any amount paid by an employer
      under section 4041(b), 4062, 4063, or 4064, or part 1 of subtitle
      E of title IV of the Employee Retirement Income Security Act of
      1974 shall be treated as a contribution to which this section
      applies by such employer to or under a stock bonus, pension,
      profit-sharing, or annuity plan.
      (2) Controlled group deductions
        In the case of a payment described in paragraph (1) made by an
      entity which is liable because it is a member of a commonly
      controlled group of corporations, trades, or businesses, within
      the meaning of subsection (b) or (c) of section 414, the fact
      that the entity did not directly employ participants of the plan
      with respect to which the liability payment was made shall not
      affect the deductibility of a payment which otherwise satisfies
      the conditions of section 162 (relating to trade or business
      expenses) or section 212 (relating to expenses for the production
      of income).
      (3) Timing of deduction of contributions
        (A) In general
          Except as otherwise provided in this paragraph, any payment
        described in paragraph (1) shall (subject to the last sentence

        paid.
        (B) Contributions under standard terminations
          Subparagraph (A) shall not apply (and subsection (a)(1)(A)
        shall apply) to any payments described in paragraph (1) which
        are paid to terminate a plan under section 4041(b) of the
        Employee Retirement Income Security Act of 1974 to the extent
        such payments result in the assets of the plan being in excess
        of the total amount of benefits under such plan which are
        guaranteed by the Pension Benefit Guaranty Corporation under
        section 4022 of such Act.
        (C) Contributions to certain trusts
          Subparagraph (A) shall not apply to any payment described in
        paragraph (1) which is made under section 4062(c) of such Act
        and such payment shall be deductible at such time as may be
        prescribed in regulations which are based on principles similar
        to the principles of subsection (a)(1)(A).
      (4) References to Employee Retirement Income Security Act of 1974
        For purposes of this subsection, any reference to a section of
      the Employee Retirement Income Security Act of 1974 shall be
      treated as a reference to such section as in effect on the date
      of the enactment of the Retirement Protection Act of 1994.
    (h) Special rules for simplified employee pensions
      (1) In general
        Employer contributions to a simplified employee pension shall
      be treated as if they are made to a plan subject to the
      requirements of this section.  Employer contributions to a
      simplified employee pension are subject to the following
      limitations:
          (A) Contributions made for a year are deductible -
            (i) in the case of a simplified employee pension maintained
          on a calendar year basis, for the taxable year with or within
          which the calendar year ends, or
            (ii) in the case of a simplified employee pension which is
          maintained on the basis of the taxable year of the employer,
          for such taxable year.
          (B) Contributions shall be treated for purposes of this
        subsection as if they were made for a taxable year if such
        contributions are made on account of such taxable year and are
        made not later than the time prescribed by law for filing the
        return for such taxable year (including extensions thereof).
          (C) The amount deductible in a taxable year for a simplified
        employee pension shall not exceed 25 percent of the
        compensation paid to the employees during the calendar year
        ending with or within the taxable year (or during the taxable
        year in the case of a taxable year described in subparagraph
        (A)(ii)). The excess of the amount contributed over the amount
        deductible for a taxable year shall be deductible in the
        succeeding taxable years in order of time, subject to the 25
        percent limit of the preceding sentence.
      (2) Effect on certain trusts
        For any taxable year for which the employer has a deduction
      under paragraph (1), the otherwise applicable limitations in
      subsection (a)(3)(A) shall be reduced by the amount of the
      allowable deductions under paragraph (1) with respect to
      participants in the trust subject to subsection (a)(3)(A).
      (3) Coordination with subsection (a)(7)
        For purposes of subsection (a)(7), a simplified employee
      pension shall be treated as if it were a separate stock bonus or
      profit-sharing trust.

          The Secretary may disallow the deduction under paragraph (1)

                                succeeding plan years (determined on the 
                                basis of the average annual increase in 
                                benefits over the 6 immediately 
                                preceding plan years).
                    (B) Limitations.--
                          (i) In general.--
                      In <<NOTE: Applicability.>> making the computation 
                      under subparagraph (A)(ii), the plan's actuary 
                      shall assume that the limitations under subsection 
                      (l) and section 415(b) shall apply.
                          ``(ii) Expected increases.--In the case of a 
                      plan year during which a plan is covered under 
                      section 4021 of the Employee Retirement Income 
                      Security Act of 1974, the plan's actuary may, 
                      notwithstanding subsection (l), take into account 
                      increases in the limitations which are expected to 
                      occur in succeeding plan years.
            (4) Special rules for plans with 100 or fewer 
        participants.--
                    (A) In general.--For purposes of determining the 
                amount under paragraph (3) for any plan year, in the 
                case of a plan which has 100 or fewer participants for 
                the plan year, the liability of the plan attributable to 
                benefit increases for highly compensated employees (as 
                defined in section 414(q)) resulting from a plan 
                amendment which is made or becomes effective, whichever 
                is later, within the last 2 years shall not be taken 
                into account in determining the target liability.
                    (B) Rule for determining number of participants.--
                For purposes of determining the number of plan 
                participants, all defined benefit plans maintained by 
                the same employer (or any member of such employer's 
                controlled group (within the meaning of section 
                412(f)(4))) shall be treated as one plan, but only 
                participants of such member or employer shall be taken 
                into account.
            (5) Special rule for terminating plans.--In the case of a 
        plan which, subject to section 4041 of the Employee Retirement 
        Income Security Act of 1974, terminates during the plan year, 
        the amount determined under paragraph (2) shall in no event be 
        less than the amount required to make the plan sufficient for 
        benefit liabilities (within the meaning of section 4041(d) of 
        such Act).
            (6) Actuarial assumptions.--Any computation under this 
        subsection for any plan year shall use the same actuarial 
        assumptions which are used for the plan year under section 430.
            (7) Definitions.--Any term used in this subsection which 
        is also used in section 430 shall have the same meaning given 
        such term by section 430.
