Sec. 401. Qualified pension, profit-sharing, and stock bonus 
        plans
        

(a) Requirements for qualification

    A trust created or organized in the United States and forming part 
of a stock bonus, pension, or profit-sharing plan of an employer for the 
exclusive benefit of his employees or their beneficiaries shall 
constitute a qualified trust under this section--
        (1) if contributions are made to the trust by such employer, or 
    employees, or both, or by another employer who is entitled to deduct 
    his contributions under section 404(a)(3)(B) (relating to deduction 
    for contributions to profit-sharing and stock bonus plans), or by a 
    charitable remainder trust pursuant to a qualified gratuitous 
    transfer (as defined in section 664(g)(1)), for the purpose of 
    distributing to such employees or their beneficiaries the corpus and 
    income of the fund accumulated by the trust in accordance with such 
    plan;
        (2) if under the trust instrument it is impossible, at any time 
    prior to the satisfaction of all liabilities with respect to 
    employees and their beneficiaries under the trust, for any part of 
    the corpus or income to be (within the taxable year or thereafter) 
    used for, or diverted to, purposes other than for the exclusive 
    benefit of his employees or their beneficiaries (but this paragraph 
    shall not be construed, in the case of a multiemployer plan, to 
    prohibit the return of a contribution within 6 months after the plan 
    administrator determines that the contribution was made by a mistake 
    of fact or law (other than a mistake relating to whether the plan is 
    described in section 401(a) or the trust which is part of such plan 
    is exempt from taxation under section 501(a), or the return of any 
    withdrawal liability payment determined to be an overpayment within 
    6 months of such determination).; \1\

        (3) if the plan of which such trust is a part satisfies the 
    requirements of section 410 (relating to minimum participation 
    standards); and
        (4) if the contributions or benefits provided under the plan do 
    not discriminate in favor of highly compensated employees (within 
    the meaning of section 414(q)). For purposes of this paragraph, 
    there shall be excluded from consideration employees described in 
    section 410(b)(3)(A) and (C).
        (5) Special rules relating to nondiscrimination requirements.--
            (A) Salaried or clerical employees.--A classification shall 
        not be considered discriminatory within the meaning of paragraph 
        (4) or section 410(b)(2)(A)(i) merely because it is limited to 
        salaried or clerical employees.
            (B) Contributions and benefits may bear uniform relationship 
        to compensation.--A plan shall not be considered discriminatory 
        within the meaning of paragraph (4) merely because the 
        contributions or benefits of, or on behalf of, the employees 
        under the plan bear a uniform relationship to the compensation 
        (within the meaning of section 414(s)) of such employees.
            (C) Certain disparity permitted.--A plan shall not be 
        considered discriminatory within the meaning of paragraph (4) 
        merely because the contributions or benefits of, or on behalf 
        of, the employees under the plan favor highly compensated 
        employees (as defined in section 414(q)) in the manner permitted 
        under subsection (l).
            (D) Integrated defined benefit plan.--
                (i) In general.--A defined benefit plan shall not be 
            considered discriminatory within the meaning of paragraph 
            (4) merely because the plan provides that the employer-
            derived accrued retirement benefit for any participant under 
            the plan may not exceed the excess (if any) of--
                    (I) the participant's final pay with the employer, 
                over
                    (II) the employer-derived retirement benefit created 
                under Federal law attributable to service by the 
                participant with the employer.

          For purposes of this clause, the employer-derived retirement 
            benefit created under Federal law shall be treated as 
            accruing ratably over 35 years.
                (ii) Final pay.--For purposes of this subparagraph, the 
            participant's final pay is the compensation (as defined in 
            section 414(q)(4)) paid to the participant by the employer 
            for any year--
                    (I) which ends during the 5-year period ending with 
                the year in which the participant separated from service 
                for the employer, and
                    (II) for which the participant's total compensation 
                from the employer was highest.

            (E) 2 or more plans treated as single plan.--For purposes of 
        determining whether 2 or more plans of an employer satisfy the 
        requirements of paragraph (4) when considered as a single plan--
                (i) Contributions.--If the amount of contributions on 
            behalf of the employees allowed as a deduction under section 
            404 for the taxable year with respect to such plans, taken 
            together, bears a uniform relationship to the compensation 
            (within the meaning of section 414(s)) of such employees, 
            the plans shall not be considered discriminatory merely 
            because the rights of employees to, or derived from, the 
            employer contributions under the separate plans do not 
            become nonforfeitable at the same rate.
                (ii) Benefits.--If the employees' rights to benefits 
            under the separate plans do not become nonforfeitable at the 
            same rate, but the levels of benefits provided by the 
            separate plans satisfy the requirements of regulations 
            prescribed by the Secretary to take account of the 
            differences in such rates, the plans shall not be considered 
            discriminatory merely because of the difference in such 
            rates.

            (F) Social security retirement age.--For purposes of testing 
        for discrimination under paragraph (4)--
                (i) the social security retirement age (as defined in 
            section 415(b)(8)) shall be treated as a uniform retirement 
            age, and
                (ii) subsidized early retirement benefits and joint and 
            survivor annuities shall not be treated as being unavailable 
            to employees on the same terms merely because such benefits 
            or annuities are based in whole or in part on an employee's 
            social security retirement age (as so defined).

            (G) State and local governmental plans.--Paragraphs (3) and 
        (4) shall not apply to a governmental plan (within the meaning 
        of section 414(d)) maintained by a State or local government or 
        political subdivision thereof (or agency or instrumentality 
        thereof).

        (6) A plan shall be considered as meeting the requirements of 
    paragraph (3) during the whole of any taxable year of the plan if on 
    one day in each quarter it satisfied such requirements.
        (7) A trust shall not constitute a qualified trust under this 
    section unless the plan of which such trust is a part satisfies the 
    requirements of section 411 (relating to minimum vesting standards).
        (8) A trust forming part of a defined benefit plan shall not 
    constitute a qualified trust under this section unless the plan 
    provides that forfeitures must not be applied to increase the 
    benefits any employee would otherwise receive under the plan.
        (9) Required distributions.--
            (A) In general.--A trust shall not constitute a qualified 
        trust under this subsection unless the plan provides that the 
        entire interest of each employee--
                (i) will be distributed to such employee not later than 
            the required beginning date, or
                (ii) will be distributed, beginning not later than the 
            required beginning date, in accordance with regulations, 
            over the life of such employee or over the lives of such 
            employee and a designated beneficiary (or over a period not 
            extending beyond the life expectancy of such employee or the 
            life expectancy of such employee and a designated 
            beneficiary).

            (B) Required distribution where employee dies before entire 
        interest is distributed.--
                (i) Where distributions have begun under subparagraph 
            (A)(ii).--A trust shall not constitute a qualified trust 
            under this section unless the plan provides that if--
                    (I) the distribution of the employee's interest has 
                begun in accordance with subparagraph (A)(ii), and
                    (II) the employee dies before his entire interest 
                has been distributed to him,

          the remaining portion of such interest will be distributed at 
            least as rapidly as under the method of distributions being 
            used under subparagraph (A)(ii) as of the date of his death.
                (ii) 5-year rule for other cases.--A trust shall not 
            constitute a qualified trust under this section unless the 
            plan provides that, if an employee dies before the 
            distribution of the employee's interest has begun in 
            accordance with subparagraph (A)(ii), the entire interest of 
            the employee will be distributed within 5 years after the 
            death of such employee.
                (iii) Exception to 5-year rule for certain amounts 
            payable over life of beneficiary.--If--
                    (I) any portion of the employee's interest is 
                payable to (or for the benefit of) a designated 
                beneficiary,
                    (II) such portion will be distributed (in accordance 
                with regulations) over the life of such designated 
                beneficiary (or over a period not extending beyond the 
                life expectancy of such beneficiary), and
                    (III) such distributions begin not later than 1 year 
                after the date of the employee's death or such later 
                date as the Secretary may by regulations prescribe,

          for purposes of clause (ii), the portion referred to in 
            subclause (I) shall be treated as distributed on the date on 
            which such distributions begin.
                (iv) Special rule for surviving spouse of employee.--If 
            the designated beneficiary referred to in clause (iii)(I) is 
            the surviving spouse of the employee--
                    (I) the date on which the distributions are required 
                to begin under clause (iii)(III) shall not be earlier 
                than the date on which the employee would have attained 
                age 70\1/2\, and
                    (II) if the surviving spouse dies before the 
                distributions to such spouse begin, this subparagraph 
                shall be applied as if the surviving spouse were the 
                employee.

            (C) Required beginning date.--For purposes of this 
        paragraph--
                (i) In general.--The term ``required beginning date'' 
            means April 1 of the calendar year following the later of--
                    (I) the calendar year in which the employee attains 
                age 70\1/2\, or
                    (II) the calendar year in which the employee 
                retires.

                (ii) Exception.--Subclause (II) of clause (i) shall not 
            apply--
                    (I) except as provided in section 409(d), in the 
                case of an employee who is a 5-percent owner (as defined 
                in section 416) with respect to the plan year ending in 
                the calendar year in which the employee attains age 
                70\1/2\, or
                    (II) for purposes of section 408(a)(6) or (b)(3).

                (iii) Actuarial adjustment.--In the case of an employee 
            to whom clause (i)(II) applies who retires in a calendar 
            year after the calendar year in which the employee attains 
            age 70\1/2\, the employee's accrued benefit shall be 
            actuarially increased to take into account the period after 
            age 70\1/2\ in which the employee was not receiving any 
            benefits under the plan.
                (iv) Exception for governmental and church plans.--
            Clauses (ii) and (iii) shall not apply in the case of a 
            governmental plan or church plan. For purposes of this 
            clause, the term ``church plan'' means a plan maintained by 
            a church for church employees, and the term ``church'' means 
            any church (as defined in section 3121(w)(3)(A)) or 
            qualified church-controlled organization (as defined in 
            section 3121(w)(3)(B)).

            (D) Life expectancy.--For purposes of this paragraph, the 
        life expectancy of an employee and the employee's spouse (other

        the term ``designated beneficiary'' means any individual 
        designated as a beneficiary by the employee.
            (F) Treatment of payments to children.--Under regulations 
        prescribed by the Secretary, for purposes of this paragraph, any 
        amount paid to a child shall be treated as if it had been paid 
        to the surviving spouse if such amount will become payable to 
        the surviving spouse upon such child reaching majority (or other 
        designated event permitted under regulations).
            (G) Treatment of incidental death benefit distributions.--
        For purposes of this title, any distribution required under the 
        incidental death benefit requirements of this subsection shall 
        be treated as a distribution required under this paragraph.

        (10) Other requirements.--
            (A) Plans benefiting owner-employees.--In the case of any 
        plan which provides contributions or benefits for employees some 
        or all of whom are owner-employees (as defined in subsection 
        (c)(3)), a trust forming part of such plan shall constitute a 
        qualified trust under this section only if the requirements of 
        subsection (d) are also met.
            (B) Top-heavy plans.--
                (i) In general.--In the case of any top-heavy plan, a 
            trust forming part of such plan shall constitute a qualified 
            trust under this section only if the requirements of section 
            416 are met.
                (ii) Plans which may become top-heavy.--Except to the 
            extent provided in regulations, a trust forming part of a 
            plan (whether or not a top-heavy plan) shall constitute a 
            qualified trust under this section only if such plan 
            contains provisions--
                    (I) which will take effect if such plan becomes a 
                top-heavy plan, and
                    (II) which meet the requirements of section 416.

                (iii) Exemption for governmental plans.--This 
            subparagraph shall not apply to any governmental plan.

        (11) Requirement of joint and survivor annuity and preretirement 
    survivor annuity.--
            (A) In general.--In the case of any plan to which this 
        paragraph applies, except as provided in section 417, a trust 
        forming part of such plan shall not constitute a qualified trust 
        under this section unless--
                (i) in the case of a vested participant who does not die 
            before the annuity starting date, the accrued benefit 
            payable to such participant is provided in the form of a 
            qualified joint and survivor annuity, and
                (ii) in the case of a vested participant who dies before 
            the annuity starting date and who has a surviving spouse, a 
            qualified preretirement survivor annuity is provided to the 
            surviving spouse of such participant.

            (B) Plans to which paragraph applies.--This paragraph shall 
        apply to--
                (i) any defined benefit plan,
                (ii) any defined contribution plan which is subject to 
            the funding standards of section 412, and
                (iii) any participant under any other defined 
            contribution plan unless--
                    (I) such plan provides that the participant's 
                nonforfeitable accrued benefit (reduced by any security 
                interest held by the plan by reason of a loan 
                outstanding to such participant) is payable in full, on 
                the death of the participant, to the participant's 
                surviving spouse (or, if there is no surviving spouse or 
                the surviving spouse consents in the manner required 
                under section 417(a)(2), to a designated beneficiary),
                    (II) such participant does not elect a payment of 
                benefits in the form of a life annuity, and
                    (III) with respect to such participant, such plan is 
                not a direct or indirect transferee (in a transfer after 
                December 31, 1984) of a plan which is described in 
                clause (i) or (ii) or to which this clause applied with 
                respect to the participant.

        Clause (iii)(III) shall apply only with respect to the 
        transferred assets (and income therefrom) if the plan separately 
        accounts for such assets and any income therefrom.
            (C) Exception for certain ESOP benefits.--
                (i) In general.--In the case of--
                    (I) a tax credit employee stock ownership plan (as 
                defined in section 409(a)), or
                    (II) an employee stock ownership plan (as defined in 
                section 4975(e)(7)),

          subparagraph (A) shall not apply to that portion of the 
            employee's accrued benefit to which the requirements of 
            section 409(h) apply.
                (ii) Nonforfeitable benefit must be paid in full, etc.--
            In the case of any participant, clause (i) shall apply only 
            if the requirements of subclauses (I), (II), and (III) of 
            subparagraph (B)(iii) are met with respect to such 
            participant.

            (D) Special rule where participant and spouse married less 
        than 1 year.--A plan shall not be treated as failing to meet the 
        requirements of subparagraphs (B)(iii) or (C) merely because the 
        plan provides that benefits will not be payable to the surviving 
        spouse of the participant unless the participant and such spouse 
        had been married throughout the 1-year period ending on the 
        earlier of the participant's annuity starting date or the date 
        of the participant's death.
            (E) Exception for plans described in section 404(c).--This 
        paragraph shall not apply to a plan which the Secretary has 
        determined is a plan described in section 404(c) (or a 
        continuation thereof) in which participation is substantially 
        limited to individuals who, before January 1, 1976, ceased 
        employment covered by the plan.
            (F) Cross reference.--For--
                (i) provisions under which participants may elect to 
            waive the requirements of this paragraph, and
                (ii) other definitions and special rules for purposes of 
            this paragraph,

        see section 417.

        (12) A trust shall not constitute a qualified trust under this 
    section unless the plan of which such trust is a part provides that 
    in the case of any merger or consolidation with, or transfer of 
    assets or liabilities to, any other plan after September 2, 1974, 
    each participant in the plan would (if the plan then terminated) 
    receive a benefit immediately after the merger, consolidation, or 
    transfer which is equal to or greater than the benefit he would have 
    been entitled to receive immediately before the merger, 
    consolidation, or transfer (if the plan had then terminated). The 
    preceding sentence does not apply to any multiemployer plan with 
    respect to any transaction to the extent that participants either 
    before or after the transaction are covered under a multiemployer 
    plan to which title IV of the Employee Retirement Income Security 
    Act of 1974 applies.
        (13) Assignment and alienation.--
            (A) In general.--A trust shall not constitute a qualified 
        trust under this section unless the plan of which such trust is 
        a part provides that benefits provided under the plan may not be 
        assigned or alienated. For purposes of the preceding sentence, 
        there shall not be taken into account any voluntary and 
        revocable assignment of not to exceed 10 percent of any benefit 
        payment made by any participant who is receiving benefits under 
        the plan unless the assignment or alienation is made for 
        purposes of defraying plan administration costs. For purposes of 
        this paragraph a loan made to a participant or beneficiary shall 
        not be treated as an assignment or alienation if such loan is 
        secured by the participant's accrued nonforfeitable benefit and 
        is exempt from the tax imposed by section 4975 (relating to tax 
        on prohibited transactions) by reason of section 4975(d)(1). 
        This paragraph shall take effect on January 1, 1976 and shall 
        not apply to assignments which were irrevocable on September 2, 
        1974.
            (B) Special rules for domestic relations orders.--
        Subparagraph (A) shall apply to the creation, assignment, or 
        recognition of a right to any benefit payable with respect to a 
        participant pursuant to a domestic relations order, except that 
        subparagraph (A) shall not apply if the order is determined to 
        be a qualified domestic relations order.
            (C) Special rule for certain judgments and settlements.--
        Subparagraph (A) shall not apply to any offset of a 
        participant's benefits provided under a plan against an amount 
        that the participant is ordered or required to pay to the plan 
        if--
                (i) the order or requirement to pay arises--
                    (I) under a judgment of conviction for a crime 
                involving such plan,
                    (II) under a civil judgment (including a consent 
                order or decree) entered by a court in an action brought 
                in connection with a violation (or alleged violation) of 
                part 4 of subtitle B of title I of the Employee 
                Retirement Income Security Act of 1974, or
                    (III) pursuant to a settlement agreement between the 
                Secretary of Labor and the participant, or a settlement 
                agreement between the Pension Benefit Guaranty 
                Corporation and the participant, in connection with a 
                violation (or alleged violation) of part 4 of such 
                subtitle by a fiduciary or any other person,

                (ii) the judgment, order, decree, or settlement 
            agreement expressly provides for the offset of all or part 
            of the amount ordered or required to be paid to the plan 
            against the participant's benefits provided under the plan, 
            and
                (iii) in a case in which the survivor annuity 
            requirements of section 401(a)(11) apply with respect to 
            distributions from the plan to the participant, if the 
            participant has a spouse at the time at which the offset is 
            to be made--
                    (I) either such spouse has consented in writing to 
                such offset and such consent is witnessed by a notary 
                public or representative of the plan (or it is 
                established to the satisfaction of a plan representative 
                that such consent may not be obtained by reason of 
                circumstances described in section 417(a)(2)(B)), or an 
                election to waive the right of the spouse to either a 
                qualified joint and survivor annuity or a qualified 
                preretirement survivor annuity is in effect in 
                accordance with the requirements of section 417(a),
                    (II) such spouse is ordered or required in such 
                judgment, order, decree, or settlement to pay an amount 
                to the plan in connection with a violation of part 4 of 
                such subtitle, or
                    (III) in such judgment, order, decree, or 
                settlement, such spouse retains the right to receive the 
                survivor annuity under a qualified joint and survivor 
                annuity provided pursuant to section 401(a)(11)(A)(i) 
                and under a qualified preretirement survivor annuity 
                provided pursuant to section 401(a)(11)(A)(ii), 
                determined in accordance with subparagraph (D).

        A plan shall not be treated as failing to meet the requirements 
        of this subsection, subsection (k), section 403(b), or section 
        409(d) solely by reason of an offset described in this 
        subparagraph.
            (D) Survivor annuity.--
                (i) In general.--The survivor annuity described in 
            subparagraph (C)(iii)(III) shall be determined as if--
                    (I) the participant terminated employment on the 
                date of the offset,
                    (II) there was no offset,
                    (III) the plan permitted commencement of benefits 
                only on or after normal retirement age,
                    (IV) the plan provided only the minimum-required 
                qualified joint and survivor annuity, and
                    (V) the amount of the qualified preretirement 
                survivor annuity under the plan is equal to the amount 
                of the survivor annuity payable under the minimum-
                required qualified joint and survivor annuity.

                (ii) Definition.--For purposes of this subparagraph, the 
            term ``minimum-required qualified joint and survivor 
            annuity'' means the qualified joint and survivor annuity 
            which is the actuarial equivalent of the participant's 
            accrued benefit (within the meaning of section 411(a)(7)) 
            and under which the survivor annuity is 50 percent of the 
            amount of the annuity which is payable during the joint 
            lives of the participant and the spouse.

        (14) A trust shall not constitute a qualified trust under this 
    section unless the plan of which such trust is a part provides that, 
    unless the participant otherwise elects, the payment of benefits 
    under the plan to the participant will begin not later than the 60th 
    day after the latest of the close of the plan year in which--
            (A) the date on which the participant attains the earlier of 
        age 65 or the normal retirement age specified under the plan,
            (B) occurs the 10th anniversary of the year in which the 
        participant commenced participation in the plan, or
            (C) the participant terminates his service with the 
        employer.

    In the case of a plan which provides for the payment of an early 
    retirement benefit, a trust forming a part of such plan shall not 
    constitute a qualified trust under this section unless a participant 
    who satisfied the service requirements for such early retirement 
    benefit, but separated from the service (with any nonforfeitable 
    right to an accrued benefit) before satisfying the age requirement 
    for such early retirement benefit, is entitled upon satisfaction of 
    such age requirement to receive a benefit not less than the benefit 
    to which he would be entitled at the normal retirement age, 
    actuarially, reduced under regulations prescribed by the Secretary.
        (15) a \2\ trust shall not constitute a qualified trust under 
    this section unless under the plan of which such trust is a part--
---------------------------------------------------------------------------
    \2\ So in original. Probably should be capitalized.
---------------------------------------------------------------------------
            (A) in the case of a participant or beneficiary who is 
        receiving benefits under such plan, or
            (B) in the case of a participant who is separated from the 
        service and who has nonforfeitable rights to benefits,

    such benefits are not decreased by reason of any increase in the 
    benefit levels payable under title II of the Social Security Act or 
    any increase in the wage base under such title II, if such increase 
    takes place after September 2, 1974, or (if later) the earlier of 
    the date of first receipt of such benefits or the date of such 
    separation, as the case may be.
        (16) A trust shall not constitute a qualified trust under this 
    section if the plan of which such trust is a part provides for 
    benefits or contributions which exceed the limitations of section 
    415.
        (17) Compensation limit.--
            (A) In general.--A trust shall not constitute a qualified 
        trust under this section unless, under the plan of which such 
        trust is a part, the annual compensation of each employee taken 
        into account under the plan for any year does not exceed 
        $200,000.
            (B) Cost-of-living adjustment.--The Secretary shall adjust 
        annually the $200,000 amount in subparagraph (A) for increases 
        in the cost-of-living at the same time and in the same manner as 
        adjustments under section 415(d); except that the base period 
        shall be the calendar quarter beginning July 1, 2001, and any 
        increase which is not a multiple of $5,000 shall be rounded to 
        the next lowest multiple of $5,000.

        [(18) Repealed. Pub. L. 97-248, title II, Sec. 237(b), Sept. 3, 
    1982, 96 Stat. 511.]
        (19) A trust shall not constitute a qualified trust under this 
    section if under the plan of which such trust is a part any part of 
    a participant's accrued benefit derived from employer contributions 
    (whether or not otherwise nonforfeitable), is forfeitable solely 
    because of withdrawal by such participant of any amount attributable 
    to the benefit derived from contributions made by such participant. 
    The preceding sentence shall not apply to the accrued benefit of any 
    participant unless, at the time of such withdrawal, such participant 
    has a nonforfeitable right to at least 50 percent of such accrued 
    benefit (as determined under section 411). The first sentence of 
    this paragraph shall not apply to the extent that an accrued benefit 
    is permitted to be forfeited in accordance with section 
    411(a)(3)(D)(iii) (relating to proportional forfeitures of benefits 
    accrued before September 2, 1974, in the event of withdrawal of 
    certain mandatory contributions).
        (20) A trust forming part of a pension plan shall not be treated 
    as failing to constitute a qualified trust under this section merely 
    because the pension plan of which such trust is a part makes 1 or 
    more distributions within 1 taxable year to a distributee on account 
    of a termination of the plan of which the trust is a part, or in the 
    case of a profit-sharing or stock bonus plan, a complete 
    discontinuance of contributions under such plan. This paragraph 
    shall not apply to a defined benefit plan unless the employer 
    maintaining such plan files a notice with the Pension Benefit 
    Guaranty Corporation (at the time and in the manner prescribed by 
    the Pension Benefit Guaranty Corporation) notifying the Corporation 
    of such payment or distribution and the Corporation has approved 
    such payment or distribution or, within 90 days after the date on 
    which such notice was filed, has failed to disapprove such payment 
    or distribution. For purposes of this paragraph, rules similar to 
    the rules of section 402(a)(6)(B) (as in effect before its repeal by 
    section 521 of the Unemployment Compensation Amendments of 1992) 
    shall apply.
        [(21) Repealed. Pub. L. 99-514, title XI, Sec. 1171(b)(5), Oct. 
    22, 1986, 100 Stat. 2513.]
        (22) If a defined contribution plan (other than a profit-sharing 
    plan)--
            (A) is established by an employer whose stock is not readily 
        tradable on an established market, and
            (B) after acquiring securities of the employer, more than 10 
        percent of the total assets of the plan are securities of the 
        employer,

    any trust forming part of such plan shall not constitute a qualified 
    trust under this section unless the plan meets the requirements of 
    subsection (e) of section 409. The requirements of subsection (e) of 
    section 409 shall not apply to any employees of an employer who are 
    participants in any defined contribution plan established and 
    maintained by such employer if the stock of such employer is not 
    readily tradable on an established market and the trade or business 
    of such employer consists of publishing on a regular basis a 
    newspaper for general circulation. For purposes of the preceding 
    sentence, subsections (b), (c), (m), and (o) of section 414 shall 
    not apply except for determining whether stock of the employer is 
    not readily tradable on an established market.
        (23) A stock bonus plan shall not be treated as meeting the 
    requirements of this section unless such plan meets the requirements 
    of subsections (h) and (o) of section 409, except that in applying 
    section 409(h) for purposes of this paragraph, the term ``employer 
    securities'' shall include any securities of the employer held by 
    the plan.
        (24) Any group trust which otherwise meets the requirements of 
    this section shall not be treated as not meeting such requirements 
    on account of the participation or inclusion in such trust of the 
    moneys of any plan or governmental unit described in section 
    818(a)(6).
        (25) Requirement that actuarial assumptions be specified.--A 
    defined benefit plan shall not be treated as providing definitely 
    determinable benefits unless, whenever the amount of any benefit is 
    to be determined on the basis of actuarial assumptions, such 
    assumptions are specified in the plan in a way which precludes 
    employer discretion.
        (26) Additional participation requirements.--
            (A) In general.--In the case of a trust which is a part of a 
        defined benefit plan, such trust shall not constitute a 
        qualified trust under this subsection unless on each day of the 
        plan year such trust benefits at least the lesser of--
                (i) 50 employees of the employer, or
                (ii) the greater of--
                    (I) 40 percent of all employees of the employer, or
                    (II) 2 employees (or if there is only 1 employee, 
                such employee).

            (B) Treatment of excludable employees.--
                (i) In general.--A plan may exclude from consideration 
            under this paragraph employees described in paragraphs (3) 
            and (4)(A) of section 410(b).
                (ii) Separate application for certain excludable 
            employees.--If employees described in section 410(b)(4)(B) 
            are covered under a plan which meets the requirements of 
            subparagraph (A) separately with respect to such employees, 
            such employees may be excluded from consideration in 
            determining whether any plan of the employer meets such 
            requirements if--
                    (I) the benefits for such employees are provided 
                under the same plan as benefits for other employees,
                    (II) the benefits provided to such employees are not 
                greater than comparable benefits provided to other 
                employees under the plan, and
                    (III) no highly compensated employee (within the 
                meaning of section 414(q)) is included in the group of 
                such employees for more than 1 year.

            (C) Eligibility to participate.--In the case of 
        contributions under section 401(k) or 401(m), employees who are 
        eligible to contribute (or may elect to have contributions made 
        on their behalf) shall be treated as benefiting under the plan.
            (D) Special rule for collective bargaining units.--Except to 
        the extent provided in regulations, a plan covering only 
        employees described in section 410(b)(3)(A) may exclude from 
        consideration any employees who are not included in the unit or 
        units in which the covered employees are included.
            (E) Paragraph not to apply to multiemployer plans.--Except 
        to the extent provided in regulations, this paragraph shall not 
        apply to employees in a multiemployer plan (within the meaning 
        of section 414(f)) who are covered by collective bargaining 
        agreements.
            (F) Special rule for certain dispositions or acquisitions.--
        Rules similar to the rules of section 410(b)(6)(C) shall apply 
        for purposes of this paragraph.
            (G) Separate lines of business.--At the election of the 
        employer and with the consent of the Secretary, this paragraph 
        may be applied separately with respect to each separate line of 
        business of the employer. For purposes of this paragraph, the 
        term ``separate line of business'' has the meaning given such 
        term by section 414(r) (without regard to paragraph (2)(A) or 
        (7) thereof).
            (H) Exception for state and local governmental plans.--This 
        paragraph shall not apply to a governmental plan (within the 
        meaning of section 414(d)) maintained by a State or local 
        government or political subdivision thereof (or agency or 
        instrumentality thereof).
            (I) Regulations.--The Secretary may by regulation provide 
        that any separate benefit structure, any separate trust, or any 
        other separate arrangement is to be treated as a separate plan 
        for purposes of applying this paragraph.

        (27) Determinations as to profit-sharing plans.--
            (A) Contributions need not be based on profits.--The 
        determination of whether the plan under which any contributions 
        are made is a profit-sharing plan shall be made without regard 
        to current or accumulated profits of the employer and without 
        regard to whether the employer is a tax-exempt organization.
            (B) Plan must designate type.--In the case of a plan which 
        is intended to be a money purchase pension plan or a profit-
        sharing plan, a trust forming part of such plan shall not 
        constitute a qualified trust under this subsection unless the 
        plan designates such intent at such time and in such manner as 
        the Secretary may prescribe.

        (28) Additional requirements relating to employee stock 
    ownership plans.--
            (A) In general.--In the case of a trust which is part of an 
        employee stock ownership plan (within the meaning of section 
        4975(e)(7)) or a plan which meets the requirements of section 
        409(a), such trust shall not constitute a qualified trust under 
        this section unless such plan meets the requirements of 
        subparagraphs (B) and (C).
            (B) Diversification of investments.--
                (i) In general.--A plan meets the requirements of this 
            subparagraph if each qualified participant in the plan may 
            elect within 90 days after the close of each plan year in 
            the qualified election period to direct the plan as to the 
            investment of at least 25 percent of the participant's 
            account in the plan (to the extent such portion exceeds the 
            amount to which a prior election under this subparagraph 
            applies). In the case of the election year in which the 
            participant can make his last election, the preceding 
            sentence shall be applied by substituting ``50 percent'' for 
            ``25 percent''.
                (ii) Method of meeting requirements.--A plan shall be 
            treated as meeting the requirements of clause (i) if--
                    (I) the portion of the participant's account covered 
                by the election under clause (i) is distributed within 
                90 days after the period during which the election may 
                be made, or
                    (II) the plan offers at least 3 investment options 
                (not inconsistent with regulations prescribed by the 
                Secretary) to each participant making an election under 
                clause (i) and within 90 days after the period during 
                which the election may be made, the plan invests the 
                portion of the participant's account covered by the 
                election in accordance with such election.

                (iii) Qualified participant.--For purposes of this 
            subparagraph, the term ``qualified participant'' means any 
            employee who has completed at least 10 years of 
            participation under the plan and has attained age 55.
                (iv) Qualified election period.--For purposes of this 
            subparagraph, the term ``qualified election period'' means 
            the 6-plan-year period beginning with the later of--
                    (I) the 1st plan year in which the individual first 
                became a qualified participant, or
                    (II) the 1st plan year beginning after December 31, 
                1986.

          For purposes of the preceding sentence, an employer may elect 
            to treat an individual first becoming a qualified 
            participant in the 1st plan year beginning in 1987 as having 
            become a participant in the 1st plan year beginning in 1988.

            (C) Use of independent appraiser.--A plan meets the 
        requirements of this subparagraph if all valuations of employer 
        securities which are not readily tradable on an established 
        securities market with respect to activities carried on by the 
        plan are by an independent appraiser. For purposes of the 
        preceding sentence, the term ``independent appraiser'' means any 
        appraiser meeting requirements similar to the requirements of 
        the regulations prescribed under section 170(a)(1).

        (29) Security required upon adoption of plan amendment resulting 
    in significant underfunding.--
            (A) In general.--If--
                (i) a defined benefit plan (other than a multiemployer 
            plan) to which the requirements of section 412 apply adopts 
            an amendment an effect of which is to increase current 
            liability under the plan for a plan year, and
                (ii) the funded current liability percentage of the plan 
            for the plan year in which the amendment takes effect is 
            less than 60 percent, including the amount of the unfunded 
            current liability under the plan attributable to the plan 
            amendment,

        the trust of which such plan is a part shall not constitute a 
        qualified trust under this subsection unless such amendment does 
        not take effect until the contributing sponsor (or any member of 
        the controlled group of the contributing sponsor) provides 
        security to the plan.
            (B) Form of security.--The security required under 
        subparagraph (A) shall consist of--
                (i) a bond issued by a corporate surety company that is 
            an acceptable surety for purposes of section 412 of the 
            Employee Retirement Income Security Act of 1974,
                (ii) cash, or United States obligations which mature in 
            3 years or less, held in escrow by a bank or similar 
            financial institution, or
                (iii) such other form of security as is satisfactory to 
            the Secretary and the parties involved.
            (C) Amount of security.--The security shall be in an amount 
        equal to the excess of--
                (i) the lesser of--
                    (I) the amount of additional plan assets which would 
                be necessary to increase the funded current liability 
                percentage under the plan to 60 percent, including the 
                amount of the unfunded current liability under the plan 
                attributable to the plan amendment, or
                    (II) the amount of the increase in current liability 
                under the plan attributable to the plan amendment and 
                any other plan amendments adopted after December 22, 
                1987, and before such plan amendment, over

                (ii) $10,000,000.

            (D) Release of security.--The security shall be released 
        (and any amounts thereunder shall be refunded together with any 
        interest accrued thereon) at the end of the first plan year 
        which ends after the provision of the security and for which the 
        funded current liability percentage under the plan is not less 
        than 60 percent. The Secretary may prescribe regulations for 
        partial releases of the security by reason of increases in the 
        funded current liability percentage.
            (E) Definitions.--For purposes of this paragraph, the terms 
        ``current liability'', ``funded current liability percentage'', 
        and ``unfunded current liability'' shall have the meanings given 
        such terms by section 412(l), except that in computing unfunded 
        current liability there shall not be taken into account any 
        unamortized portion of the unfunded old liability amount as of 
        the close of the plan year.

        (30) Limitations on elective deferrals.--In the case of a trust 
    which is part of a plan under which elective deferrals (within the 
    meaning of section 402(g)(3)) may be made with respect to any 
    individual during a calendar year, such trust shall not constitute a 
    qualified trust under this subsection unless the plan provides that 
    the amount of such deferrals under such plan and all other plans, 
    contracts, or arrangements of an employer maintaining such plan may 
    not exceed the amount of the limitation in effect under section 
    402(g)(1) for taxable years beginning in such calendar year.

        (31) Direct transfer of eligible rollover distributions.--
            (A) In general.--A trust shall not constitute a qualified 
        trust under this section unless the plan of which such trust is 
        a part provides that if the distributee of any eligible rollover 
        distribution--
                (i) elects to have such distribution paid directly to an 
            eligible retirement plan, and
                (ii) specifies the eligible retirement plan to which 
            such distribution is to be paid (in such form and at such 
            time as the plan administrator may prescribe),

        such distribution shall be made in the form of a direct trustee-
        to-trustee transfer to the eligible retirement plan so 
        specified.
            (B) Certain mandatory distributions.--
                (i) In general.--In case of a trust which is part of an 
            eligible plan, such trust shall not constitute a qualified 
            trust under this section unless the plan of which such trust 
            is a part provides that if--
                    (I) a distribution described in clause (ii) in 
                excess of $1,000 is made, and
                    (II) the distributee does not make an election under 
                subparagraph (A) and does not elect to receive the 
                distribution directly,

          the plan administrator shall make such transfer to an 
            individual retirement plan of a designated trustee or issuer 
            and shall notify the distributee in writing (either 
            separately or as part of the notice under section 402(f)) 
            that the distribution may be transferred to another 
            individual retirement plan.
                (ii) Eligible plan.--For purposes of clause (i), the 
            term ``eligible plan'' means a plan which provides that any 
            nonforfeitable accrued benefit for which the present value 
            (as determined under section 411(a)(11)) does not exceed 
            $5,000 shall be immediately distributed to the participant.
            (C) Limitation.--Subparagraphs (A) and (B) shall apply only 
        to the extent that the eligible rollover distribution would be 
        includible in gross income if not transferred as provided in 
        subparagraph (A) (determined without regard to sections 402(c), 
        403(a)(4), 403(b)(8), and 457(e)(16)). The preceding sentence 
        shall not apply to such distribution if the plan to which such 
        distribution is transferred--
                (i) agrees to separately account for amounts so 
            transferred, including separately accounting for the portion 
            of such distribution which is includible in gross income and 
            the portion of such distribution which is not so includible, 
            or
                (ii) is an eligible retirement plan described in clause 
            (i) or (ii) of section 402(c)(8)(B).

            (D) Eligible rollover distribution.--For purposes of this 
        paragraph, the term ``eligible rollover distribution'' has the 
        meaning given such term by section 402(f)(2)(A).
            (E) Eligible retirement plan.--For purposes of this 
        paragraph, the term ``eligible retirement plan'' has the meaning 
        given such term by section 402(c)(8)(B), except that a qualified 
        trust shall be considered an eligible retirement plan only if it 
        is a defined contribution plan, the terms of which permit the 
        acceptance of rollover distributions.

        (32) Treatment of failure to make certain payments if plan has 
    liquidity shortfall.--
            (A) In general.--A trust forming part of a pension plan to 
        which section 412(m)(5) applies shall not be treated as failing 
        to constitute a qualified trust under this section merely 
        because such plan ceases to make any payment described in 
        subparagraph (B) during any period that such plan has a 
        liquidity shortfall (as defined in section 412(m)(5)).
            (B) Payments described.--A payment is described in this 
        subparagraph if such payment is--
                (i) any payment, in excess of the monthly amount paid 
            under a single life annuity (plus any social security 
            supplements described in the last sentence of section 
            411(a)(9)), to a participant or beneficiary whose annuity 
            starting date (as defined in section 417(f)(2)) occurs 
            during the period referred to in subparagraph (A),
                (ii) any payment for the purchase of an irrevocable 
            commitment from an insurer to pay benefits, and
                (iii) any other payment specified by the Secretary by 
            regulations.

            (C) Period of shortfall.--For purposes of this paragraph, a 
        plan has a liquidity shortfall during the period that there is 
        an underpayment of an installment under section 412(m) by reason 
        of paragraph (5)(A) thereof.

        (33) Prohibition on benefit increases while sponsor is in 
    bankruptcy.--
            (A) In general.--A trust which is part of a plan to which 
        this paragraph applies shall not constitute a qualified trust 
        under this section if an amendment to such plan is adopted while 
        the employer is a debtor in a case under title 11, United States 
        Code, or similar Federal or State law, if such amendment 
        increases liabilities of the plan by reason of--
                (i) any increase in benefits,
                (ii) any change in the accrual of benefits, or
                (iii) any change in the rate at which benefits become 
            nonforfeitable under the plan,

        with respect to employees of the debtor, and such amendment is 
        effective prior to the effective date of such employer's plan of 
        reorganization.
            (B) Exceptions.--This paragraph shall not apply to any plan 
        amendment if--
                (i) the plan, were such amendment to take effect, would 
            have a funded current liability percentage (as defined in 
            section 412(l)(8)) of 100 percent or more,
                (ii) the Secretary determines that such amendment is 
            reasonable and provides for only de minimis increases in the 
            liabilities of the plan with respect to employees of the 
            debtor,
                (iii) such amendment only repeals an amendment described 
            in subsection 412(c)(8), or
                (iv) such amendment is required as a condition of 
            qualification under this part.

            (C) Plans to which this paragraph applies.--This paragraph 
        shall apply only to plans (other than multiemployer plans) 
        covered under section 4021 of the Employee Retirement Income 
        Security Act of 1974.
            (D) Employer.--For purposes of this paragraph, the term 
        ``employer'' means the employer referred to in section 
        412(c)(11) (without regard to subparagraph (B) thereof).

        (34) Benefits of missing participants on plan termination.--In 
    the case of a plan covered by title IV of the Employee Retirement 
    Income Security Act of 1974, a trust forming part of such plan shall 
    not be treated as failing to constitute a qualified trust under this 
    section merely because the pension plan of which such trust is a 
    part, upon its termination, transfers benefits of missing 
    participants to the Pension Benefit Guaranty Corporation in 
    accordance with section 4050 of such Act.

Paragraphs (11), (12), (13), (14), (15), (19), and (20) shall apply only 
in the case of a plan to which section 411 (relating to minimum vesting 
standards) applies without regard to subsection (e)(2) of such section.

(b) Certain retroactive changes in plan

    A stock bonus, pension, profit-sharing, or annuity plan shall be 
considered as satisfying the requirements of subsection (a) for the 
period beginning with the date on which it was put into effect, or for 
the period beginning with the earlier of the date on which there was 
adopted or put into effect any amendment which caused the plan to fail 
to satisfy such requirements, and ending with the time prescribed by law 
for filing the return of the employer for his taxable year in which such 
plan or amendment was adopted (including extensions thereof) or such 
later time as the Secretary may designate, if all provisions of the plan 
which are necessary to satisfy such requirements are in effect by the 
end of such period and have been made effective for all purposes for the 
whole of such period.

        owner-employees

            and
                (ii) an individual who has been a self-employed

(f) Certain custodial accounts and contracts

    For purposes of this title, a custodial account, an annuity 
contract, or a contract (other than a life, health or accident, 
property, casualty, or liability insurance contract) issued by an 
insurance company qualified to do business in a State shall be treated 
as a qualified trust under this section if--
        (1) the custodial account or contract would, except for the fact 
    that it is not a trust, constitute a qualified trust under this 
    section, and

(h) Medical, etc., benefits for retired employees and their spouses and 
        dependents

    Under regulations prescribed by the Secretary, and subject to the 
provisions of section 420, a pension or annuity plan may provide for the 
payment of benefits for sickness, accident, hospitalization, and medical 
expenses of retired employees, their spouses and their dependents, but 
only if--
        (1) such benefits are subordinate to the retirement benefits 
    provided by the plan,
        (2) a separate account is established and maintained for such 
    benefits,
        (3) the employer's contributions to such separate account are 
    reasonable and ascertainable,

    all liabilities under the plan to provide such benefits, for any 
    part of the corpus or income of such separate account to be (within 
    the taxable year or thereafter) used for, or diverted to, any 
    purpose other than the providing of such benefits,
        (5) notwithstanding the provisions of subsection (a)(2), upon 
    the satisfaction of all liabilities under the plan to provide such 
    benefits, any amount remaining in such separate account must, under 
    the terms of the plan, be returned to the employer, and
        (6) in the case of an employee who is a key employee, a separate 
    account is established and maintained for such benefits payable to 
    such employee (and his spouse and dependents) and such benefits (to 
    the extent attributable to plan years beginning after March 31, 
    1984, for which the employee is a key employee) are only payable to 
    such employee (and his spouse and dependents) from such separate 
    account.

For purposes of paragraph (6), the term ``key employee'' means any 
employee, who at any time during the plan year or any preceding plan 
year during which contributions were made on behalf of such employee, is 
or was a key employee as defined in section 416(i). In no event shall 
the requirements of paragraph (1) be treated as met if the aggregate 
actual contributions for medical benefits, when added to actual 
contributions for life insurance protection under the plan, exceed 25 
percent of the total actual contributions to the plan (other than 
contributions to fund past service credits) after the date on which the 
account is established.

(i) Certain union-negotiated pension plans

    In the case of a trust forming part of a pension plan which has been 
determined by the Secretary to constitute a qualified trust under 
subsection (a) and to be exempt from taxation under section 501(a) for a 
period beginning after contributions were first made to or for such 
trust, if it is shown to the satisfaction of the Secretary that--
        (1) such trust was created pursuant to a collective bargaining 
    agreement between employee representatives and one or more 
    employers,
        (2) any disbursements of contributions, made to or for such 
    trust before the time as of which the Secretary or his delegate 
    determined that the trust constituted a qualified trust, 
    substantially complied with the terms of the trust, and the plan of 
    which the trust is a part, as subsequently qualified, and
        (3) before the time as of which the Secretary determined that 
    the trust constitutes a qualified trust, the contributions to or for 
    such trust were not used in a manner which would jeopardize the 
    interests of its beneficiaries,

then such trust shall be considered as having constituted a qualified 
trust under subsection (a) and as having been exempt from taxation under 
section 501(a) for the period beginning on the date on which 
contributions were first made to or for such trust and ending on the 
date such trust first constituted (without regard to this subsection) a 
qualified trust under subsection (a).

(k) Cash or deferred arrangements

                          (1) General rule

        A profit-sharing or stock bonus plan, a pre-ERISA money purchase 
    plan, or a rural cooperative plan shall not be considered as not 
    satisfying the requirements of subsection (a) merely because the 
    plan includes a qualified cash or deferred arrangement.

             (2) Qualified cash or deferred arrangement

        A qualified cash or deferred arrangement is any arrangement 
    which is part of a profit-sharing or stock bonus plan, a pre-ERISA 
    money purchase plan, or a rural cooperative plan which meets the 
    requirements of subsection (a)--
            (A) under which a covered employee may elect to have the 
        employer make payments as contributions to a trust under the 
        plan on behalf of the employee, or to the employee directly in 
        cash;
            (B) under which amounts held by the trust which are 
        attributable to employer contributions made pursuant to the 
        employee's election--
                (i) may not be distributable to participants or other 
            beneficiaries earlier than--
                    (I) severance from employment, death, or disability,
                    (II) an event described in paragraph (10),
                    (III) in the case of a profit-sharing or stock bonus 
                plan, the attainment of age 59\1/2\, or
                    (IV) in the case of contributions to a profit-
                sharing or stock bonus plan to which section 402(e)(3) 
                applies, upon hardship of the employee, and

                (ii) will not be distributable merely by reason of the 
            completion of a stated period of participation or the lapse 
            of a fixed number of years;

            (C) which provides that an employee's right to his accrued 
        benefit derived from employer contributions made to the trust 
        pursuant to his election is nonforfeitable, and
            (D) which does not require, as a condition of participation 
        in the arrangement, that an employee complete a period of 
        service with the employer (or employers) maintaining the plan 
        extending beyond the period permitted under section 410(a)(1) 
        (determined without regard to subparagraph (B)(i) thereof).

        (3) Application of participation and discrimination 
                                  standards

            (A) A cash or deferred arrangement shall not be treated as a 
        qualified cash or deferred arrangement unless--
                (i) those employees eligible to benefit under the 
            arrangement satisfy the provisions of section 410(b)(1), and
                (ii) the actual deferral percentage for eligible highly 
            compensated employees (as defined in paragraph (5)) for the 
            plan year bears a relationship to the actual deferral 
            percentage for all other eligible employees for the 
            preceding plan year which meets either of the following 
            tests:
                    (I) The actual deferral percentage for the group of 
                eligible highly compensated employees is not more than 
                the actual deferral percentage of all other eligible 
                employees multiplied by 1.25.
                    (II) The excess of the actual deferral percentage 
                for the group of eligible highly compensated employees 
                over that of all other eligible employees is not more 
                than 2 percentage points, and the actual deferral 
                percentage for the group of eligible highly compensated 
                employees is not more than the actual deferral 
                percentage of all other eligible employees multiplied by 
                2.

          If 2 or more plans which include cash or deferred arrangements 
            are considered as 1 plan for purposes of section 401(a)(4) 
            or 410(b), the cash or deferred arrangements included in 
            such plans shall be treated as 1 arrangement for purposes of 
            this subparagraph.

        If any highly compensated employee is a participant under 2 or 
        more cash or deferred arrangements of the employer, for purposes 
        of determining the deferral percentage with respect to such 
        employee, all such cash or deferred arrangements shall be 
        treated as 1 cash or deferred arrangement. An arrangement may 
        apply clause (ii) by using the plan year rather than the 
        preceding plan year if the employer so elects, except that if 
        such an election is made, it may not be changed except as 
        provided by the Secretary.
            (B) For purposes of subparagraph (A), the actual deferral 
        percentage for a specified group of employees for a plan year 
        shall be the average of the ratios (calculated separately for 
        each employee in such group) of--
                (i) the amount of employer contributions actually paid 
            over to the trust on behalf of each such employee for such 
            plan year, to
                (ii) the employee's compensation for such plan year.

            (C) A cash or deferred arrangement shall be treated as 
        meeting the requirements of subsection (a)(4) with respect to 
        contributions if the requirements of subparagraph (A)(ii) are 
        met.
            (D) For purposes of subparagraph (B), the employer 
        contributions on behalf of any employee--
                (i) shall include any employer contributions made 
            pursuant to the employee's election under paragraph (2), and
                (ii) under such rules as the Secretary may prescribe, 
            may, at the election of the employer, include--
                    (I) matching contributions (as defined in 
                401(m)(4)(A)) which meet the requirements of paragraph 
                (2)(B) and (C), and
                    (II) qualified nonelective contributions (within the 
                meaning of section 401(m)(4)(C)).

            (E) For purposes of this paragraph, in the case of the first 
        plan year of any plan (other than a successor plan), the amount 
        taken into account as the actual deferral percentage of 
        nonhighly compensated employees for the preceding plan year 
        shall be--
                (i) 3 percent, or
                (ii) if the employer makes an election under this 
            subclause, the actual deferral percentage of nonhighly 
            compensated employees determined for such first plan year.

            (F) Special rule for early participation.--If an employer 
        elects to apply section 410(b)(4)(B) in determining whether a 
        cash or deferred arrangement meets the requirements of 
        subparagraph (A)(i), the employer may, in determining whether 
        the arrangement meets the requirements of subparagraph (A)(ii), 
        exclude from consideration all eligible employees (other than 
        highly compensated employees) who have not met the minimum age 
        and service requirements of section 410(a)(1)(A).
            (G) A governmental plan (within the meaning of section 
        414(d)) maintained by a State or local government or political 
        subdivision thereof (or agency or instrumentality thereof) shall 
        be treated as meeting the requirements of this paragraph.

                       (4) Other requirements

        (A) Benefits (other than matching contributions) must not be 
                contingent on election to defer

            A cash or deferred arrangement of any employer shall not be 
        treated as a qualified cash or deferred arrangement if any other 
        benefit is conditioned (directly or indirectly) on the employee 
        electing to have the employer make or not make contributions 
        under the arrangement in lieu of receiving cash. The preceding 
        sentence shall not apply to any matching contribution (as 
        defined in section 401(m)) made by reason of such an election.

        (B) Eligibility of State and local governments and tax-exempt 
                organizations

            (i) Tax-exempts eligible

                Except as provided in clause (ii), any organization 
            exempt from tax under this subtitle may include a qualified 
            cash or deferred arrangement as part of a plan maintained by 
            it.
            (ii) Governments ineligible

                A cash or deferred arrangement shall not be treated as a 
            qualified cash or deferred arrangement if it is part of a 
            plan maintained by a State or local government or political 
            subdivision thereof, or any agency or instrumentality 
            thereof. This clause shall not apply to a rural cooperative 
            plan or to a plan of an employer described in clause (iii).
            (iii) Treatment of Indian tribal governments

                An employer which is an Indian tribal government (as 
            defined in section 7701(a)(40)), a subdivision of an Indian 
            tribal government (determined in accordance with section 
            7871(d)), an agency or instrumentality of an Indian tribal 
            government or subdivision thereof, or a corporation 
            chartered under Federal, State, or tribal law which is owned 
            in whole or in part by any of the foregoing may include a 
            qualified cash or deferred arrangement as part of a plan 
            maintained by the employer.

        (C) Coordination with other plans

            Except as provided in section 401(m), any employer 
        contribution made pursuant to an employee's election under a 
        qualified cash or deferred arrangement shall not be taken into 
        account for purposes of determining whether any other plan meets 
        the requirements of section 401(a) or 410(b). This subparagraph 
        shall not apply for purposes of determining whether a plan meets 
        the average benefit requirement of section 410(b)(2)(A)(ii).

                   (5) Highly compensated employee

        For purposes of this subsection, the term ``highly compensated 
    employee'' has the meaning given such term by section 414(q).

                  (6) Pre-ERISA money purchase plan

        such date, included a salary reduction arrangement, and
            (C) under which neither the employee contributions nor the 
        employer contributions may exceed the levels provided for by the 
        contribution formula in effect under the plan on such date.

                     (7) Rural cooperative plan

        (A) In general

        (C) Special rule for certain distributions

            A rural cooperative plan which includes a qualified cash or 
        deferred arrangement shall not be treated as violating the 
        requirements of section 401(a) or of paragraph (2) merely by 
        reason of a hardship distribution or a distribution to a 
        participant after attainment of age 59\1/2\. For purposes of 
        this section, the term ``hardship distribution'' means a 
        distribution described in paragraph (2)(B)(i)(IV) (without 
        regard to the limitation of its application to profit-sharing or 
        stock bonus plans).

      (8) Arrangement not disqualified if excess contributions 
                                 distributed

        (A) In general

            A cash or deferred arrangement shall not be treated as 
        failing to meet the requirements of clause (ii) of paragraph 
        (3)(A) for any plan year if, before the close of the following 
        plan year--
                (i) the amount of the excess contributions for such plan 
            year (and any income allocable to such contributions) is 
            distributed, or
                (ii) to the extent provided in regulations, the employee 
            elects to treat the amount of the excess contributions as an 
            amount distributed to the employee and then contributed by 
            the employee to the plan.

        Any distribution of excess contributions (and income) may be 
        made without regard to any other provision of law.

        (B) Excess contributions

            For purposes of subparagraph (A), the term ``excess 
        contributions'' means, with respect to any plan year, the excess 
        of--
                (i) the aggregate amount of employer contributions 
            actually paid over to the trust on behalf of highly 
            compensated employees for such plan year, over
                (ii) the maximum amount of such contributions permitted 
            under the limitations of clause (ii) of paragraph (3)(A) 
            (determined by reducing contributions made on behalf of 
            highly compensated employees in order of the actual deferral 
            percentages beginning with the highest of such percentages).

        (C) Method of distributing excess contributions

            Any distribution of the excess contributions for any plan 
        year shall be made to highly compensated employees on the basis 
        of the amount of contributions by, or on behalf of, each of such 
        employees.

        (D) Additional tax under section 72(t) not to apply

            No tax shall be imposed under section 72(t) on any amount 
        required to be distributed under this paragraph.

        (E) Treatment of matching contributions forfeited by reason of 
                excess deferral or contribution

            For purposes of paragraph (2)(C), a matching contribution 
        (within the meaning of subsection (m)) shall not be treated as 
        forfeitable merely because such contribution is forfeitable if 
        the contribution to which the matching contribution relates is 
        treated as an excess contribution under subparagraph (B), an 
        excess deferral under section 402(g)(2)(A), or an excess 
        aggregate contribution under section 401(m)(6)(B).

        (F) Cross reference

            For excise tax on certain excess contributions, see section 
        4979.

                          (9) Compensation

        For purposes of this subsection, the term ``compensation'' has 
    the meaning given such term by section 414(s).

             (10) Distributions upon termination of plan

        (A) In general

            An event described in this subparagraph is the termination 
        of the plan without establishment or maintenance of another 
        defined contribution plan (other than an employee stock 
        ownership plan as defined in section 4975(e)(7)).

        (B) Distributions must be lump sum distributions

            (i) In general

                A termination shall not be treated as described in 
            subparagraph (A) with respect to any employee unless the 
            employee receives a lump sum distribution by reason of the 
            termination.
            (ii) Lump-sum distribution

                For purposes of this subparagraph, the term ``lump-sum 
            distribution'' has the meaning given such term by section 
            402(e)(4)(D) (without regard to subclauses (I), (II), (III), 
            and (IV) of clause (i) thereof). Such term includes a 
            distribution of an annuity contract from--
                    (I) a trust which forms a part of a plan described 
                in section 401(a) and which is exempt from tax under 
                section 501(a), or
                    (II) an annuity plan described in section 403(a).

    (11) Adoption of simple plan to meet nondiscrimination tests

        (A) In general

            A cash or deferred arrangement maintained by an eligible 
        employer shall be treated as meeting the requirements of 
        paragraph (3)(A)(ii) if such arrangement meets--
                (i) the contribution requirements of subparagraph (B),
                (ii) the exclusive plan requirements of subparagraph 
            (C), and
                (iii) the vesting requirements of section 408(p)(3).

        (B) Contribution requirements

            (i) In general

                The requirements of this subparagraph are met if, under 
            the arrangement--
                    (I) an employee may elect to have the employer make 
                elective contributions for the year on behalf of the 
                employee to a trust under the plan in an amount which is 
                expressed as a percentage of compensation of the 
                employee but which in no event exceeds the amount in 
                effect under section 408(p)(2)(A)(ii),
                    (II) the employer is required to make a matching 
                contribution to the trust for the year in an amount 
                equal to so much of the amount the employee elects under 
                subclause (I) as does not exceed 3 percent of 
                compensation for the year, and
                    (III) no other contributions may be made other than 
                contributions described in subclause (I) or (II).
            (ii) Employer may elect 2-percent nonelective 
                    contribution

                An employer shall be treated as meeting the requirements 
            of clause (i)(II) for any year if, in lieu of the 
            contributions described in such clause, the employer elects 
            (pursuant to the terms of the arrangement) to make 
            nonelective contributions of 2 percent of compensation for 
            each employee who is eligible to participate in the 
            arrangement and who has at least $5,000 of compensation from 
            the employer for the year. If an employer makes an election 
            under this subparagraph for any year, the employer shall 
            notify employees of such election within a reasonable period 
            of time before the 60th day before the beginning of such 
            year.
            (iii) Administrative requirements

                (I) In general

                    Rules similar to the rules of subparagraphs (B) and 
                (C) of section 408(p)(5) shall apply for purposes of 
                this subparagraph.
                (II) Notice of election period

                    The requirements of this subparagraph shall not be 
                treated as met with respect to any year unless the 
                employer notifies each employee eligible to participate, 
                within a reasonable period of time before the 60th day 
                before the beginning of such year (and, for the first 
                year the employee is so eligible, the 60th day before 
                the first day such employee is so eligible), of the 
                rules similar to the rules of section 408(p)(5)(C) which 
                apply by reason of subclause (I).

        (C) Exclusive plan requirement

            The requirements of this subparagraph are met for any year 
        to which this paragraph applies if no contributions were made, 
        or benefits were accrued, for services during such year under 
        any qualified plan of the employer on behalf of any employee 
        eligible to participate in the cash or deferred arrangement, 
        other than contributions described in subparagraph (B).

        (D) Definitions and special rule

            (i) Definitions

                For purposes of this paragraph, any term used in this 
            paragraph which is also used in section 408(p) shall have 
            the meaning given such term by such section.
            (ii) Coordination with top-heavy rules

                A plan meeting the requirements of this paragraph for 
            any year shall not be treated as a top-heavy plan under 
            section 416 for such year if such plan allows only 
            contributions required under this paragraph.

       (12) Alternative methods of meeting nondiscrimination 
                                requirements

        (A) In general

            A cash or deferred arrangement shall be treated as meeting 
        the requirements of paragraph (3)(A)(ii) if such arrangement--
                (i) meets the contribution requirements of subparagraph 
            (B) or (C), and
                (ii) meets the notice requirements of subparagraph (D).

        (B) Matching contributions

            (i) In general

                The requirements of this subparagraph are met if, under 
            the arrangement, the employer makes matching contributions 
            on behalf of each employee who is not a highly compensated 
            employee in an amount equal to--
                    (I) 100 percent of the elective contributions of the 
                employee to the extent such elective contributions do 
                not exceed 3 percent of the employee's compensation, and
                    (II) 50 percent of the elective contributions of the 
                employee to the extent that such elective contributions 
                exceed 3 percent but do not exceed 5 percent of the 
                employee's compensation.
            (ii) Rate for highly compensated employees

                The requirements of this subparagraph are not met if, 
            under the arrangement, the rate of matching contribution 
            with respect to any elective contribution of a highly 
            compensated employee at any rate of elective contribution is 
            greater than that with respect to an employee who is not a 
            highly compensated employee.
            (iii) Alternative plan designs

                If the rate of any matching contribution with respect to 
            any rate of elective contribution is not equal to the 
            percentage required under clause (i), an arrangement shall 
            not be treated as failing to meet the requirements of clause 
            (i) if--
                    (I) the rate of an employer's matching contribution 
                does not increase as an employee's rate of elective 
                contributions increase, and
                    (II) the aggregate amount of matching contributions 
                at such rate of elective contribution is at least equal 
                to the aggregate amount of matching contributions which 
                would be made if matching contributions were made on the 
                basis of the percentages described in clause (i).

        (C) Nonelective contributions

            The requirements of this subparagraph are met if, under the 
        arrangement, the employer is required, without regard to whether 
        the employee makes an elective contribution or employee 
        contribution, to make a contribution to a defined contribution 
        plan on behalf of each employee who is not a highly compensated 
        employee and who is eligible to participate in the arrangement 
        in an amount equal to at least 3 percent of the employee's 
        compensation.

        (D) Notice requirement

            An arrangement meets the requirements of this paragraph if, 
        under the arrangement, each employee eligible to participate is, 
        within a reasonable period before any year, given written notice 
        of the employee's rights and obligations under the arrangement 
        which--
                (i) is sufficiently accurate and comprehensive to 
            apprise the employee of such rights and obligations, and
                (ii) is written in a manner calculated to be understood 
            by the average employee eligible to participate.

        (E) Other requirements

            (i) Withdrawal and vesting restrictions

                An arrangement shall not be treated as meeting the 
            requirements of subparagraph (B) or (C) of this paragraph 
            unless the requirements of subparagraphs (B) and (C) of 
            paragraph (2) are met with respect to all employer 
            contributions (including matching contributions) taken into 
            account in determining whether the requirements of 
            subparagraphs (B) and (C) of this paragraph are met.
            (ii) Social security and similar contributions not 
                    taken into account

                An arrangement shall not be treated as meeting the 
            requirements of subparagraph (B) or (C) unless such 
            requirements are met without regard to subsection (l), and, 
            for purposes of subsection (l), employer contributions under 
            subparagraph (B) or (C) shall not be taken into account.

        (F) Other plans

            An arrangement shall be treated as meeting the requirements 
        under subparagraph (A)(i) if any other plan maintained by the 
        employer meets such requirements with respect to employees 
        eligible under the arrangement.

(l) Permitted disparity in plan contributions or benefits

                           (1) In general

        The requirements of this subsection are met with respect to a 
    plan if--
            (A) in the case of a defined contribution plan, the 
        requirements of paragraph (2) are met, and
            (B) in the case of a defined benefit plan, the requirements 
        of paragraph (3) are met.

                    (2) Defined contribution plan

        (A) In general

            A defined contribution plan meets the requirements of this 
        paragraph if the excess contribution percentage does not exceed 
        the base contribution percentage by more than the lesser of--
                (i) the base contribution percentage, or
                (ii) the greater of--
                    (I) 5.7 percentage points, or
                    (II) the percentage equal to the portion of the rate 
                of tax under section 3111(a) (in effect as of the 
                beginning of the year) which is attributable to old-age 
                insurance.

        (B) Contribution percentages

            For purposes of this paragraph--
            (i) Excess contribution percentage

                The term ``excess contribution percentage'' means the 
            percentage of compensation which is contributed by the 
            employer under the plan with respect to that portion of each 
            participant's compensation in excess of the integration 
            level.
            (ii) Base contribution percentage

                The term ``base contribution percentage'' means the 
            percentage of compensation contributed by the employer under 
            the plan with respect to that portion of each participant's 
            compensation not in excess of the integration level.

                      (3) Defined benefit plan

        A defined benefit plan meets the requirements of this paragraph 
    if--

        (A) Excess plans

            (i) In general

                In the case of a plan other than an offset plan--
                    (I) the excess benefit percentage does not exceed 
                the base benefit percentage by more than the maximum 
                excess allowance,
                    (II) any optional form of benefit, preretirement 
                benefit, actuarial factor, or other benefit or feature 
                provided with respect to compensation in excess of the 
                integration level is provided with respect to 
                compensation not in excess of such level, and
                    (III) benefits are based on average annual 
                compensation.
            (ii) Benefit percentages

                For purposes of this subparagraph, the excess and base 
            benefit percentages shall be computed in the same manner as 
            the excess and base contribution percentages under paragraph 
            (2)(B), except that such determination shall be made on the 
            basis of benefits attributable to employer contributions 
            rather than contributions.

        (B) Offset plans

            In the case of an offset plan, the plan provides that--
                (i) a participant's accrued benefit attributable to 
            employer contributions (within the meaning of section 
            411(c)(1)) may not be reduced (by reason of the offset) by 
            more than the maximum offset allowance, and
                (ii) benefits are based on average annual compensation.

              (4) Definitions relating to paragraph (3)

        For purposes of paragraph (3)--

        (A) Maximum excess allowance

            The maximum excess allowance is equal to--
                (i) in the case of benefits attributable to any year of 
            service with the employer taken into account under the plan, 
            \3/4\ of a percentage point, and
                (ii) in the case of total benefits, \3/4\ of a 
            percentage point, multiplied by the participant's years of 
            service (not in excess of 35) with the employer taken into 
            account under the plan.

        In no event shall the maximum excess allowance exceed the base 
        benefit percentage.

        (B) Maximum offset allowance

            The maximum offset allowance is equal to--
                (i) in the case of benefits attributable to any year of 
            service with the employer taken into account under the plan, 
            \3/4\ percent of the participant's final average 
            compensation, and
                (ii) in the case of total benefits, \3/4\ percent of the 
            participant's final average compensation, multiplied by the 
            participant's years of service (not in excess of 35) with 
            the employer taken into account under the plan.

        In no event shall the maximum offset allowance exceed 50 percent 
        of the benefit which would have accrued without regard to the 
        offset reduction.

        (C) Reductions

            (i) In general

                The Secretary shall prescribe regulations requiring the 
            reduction of the \3/4\ percentage factor under subparagraph 
            (A) or (B)--
                    (I) in the case of a plan other than an offset plan 
                which has an integration level in excess of covered 
                compensation, or
                    (II) with respect to any participant in an offset 
                plan who has final average compensation in excess of 
                covered compensation.
            (ii) Basis of reductions

                Any reductions under clause (i) shall be based on the 
            percentages of compensation replaced by the employer-derived 
            portions of primary insurance amounts under the Social 
            Security Act for participants with compensation in excess of 
            covered compensation.

        (D) Offset plan

            The term ``offset plan'' means any plan with respect to 
        which the benefit attributable to employer contributions for 
        each participant is reduced by an amount specified in the plan.

               (5) Other definitions and special rules

        For purposes of this subsection--

        (A) Integration level

            (i) In general

                The term ``integration level'' means the amount of 
            compensation specified under the plan (by dollar amount or 
            formula) at or below which the rate at which contributions 
            or benefits are provided (expressed as a percentage) is less 
            than such rate above such amount.
            (ii) Limitation

                The integration level for any year may not exceed the 
            contribution and benefit base in effect under section 230 of 
            the Social Security Act for such year.
            (iii) Level to apply to all participants

                A plan's integration level shall apply with respect to 
            all participants in the plan.
            (iv) Multiple integration levels

                Under rules prescribed by the Secretary, a defined 
            benefit plan may specify multiple integration levels.

        (B) Compensation

            The term ``compensation'' has the meaning given such term by 
        section 414(s).

        (C) Average annual compensation

            The term ``average annual compensation'' means the 
        participant's highest average annual compensation for--
                (i) any period of at least 3 consecutive years, or
                (ii) if shorter, the participant's full period of 
            service.

        (D) Final average compensation

            (i) In general

                The term ``final average compensation'' means the 
            participant's average annual compensation for--
                    (I) the 3-consecutive year period ending with the 
                current year, or
                    (II) if shorter, the participant's full period of 
                service.
            (ii) Limitation

                A participant's final average compensation shall be 
            determined by not taking into account in any year 
            compensation in excess of the contribution and benefit base 
            in effect under section 230 of the Social Security Act for 
            such year.

        (E) Covered compensation

            (i) In general

                The term ``covered compensation'' means, with respect to 
            an employee, the average of the contribution and benefit 
            bases in effect under section 230 of the Social Security Act 
            for each year in the 35-year period ending with the year in 
            which the employee attains the social security retirement 
            age.
            (ii) Computation for any year

                For purposes of clause (i), the determination for any 
            year preceding the year in which the employee attains the 
            social security retirement age shall be made by assuming 
            that there is no increase in the bases described in clause 
            (i) after the determination year and before the employee 
            attains the social security retirement age.
            (iii) Social security retirement age

                For purposes of this subparagraph, the term ``social 
            security retirement age'' has the meaning given such term by 
            section 415(b)(8).

        (F) Regulations

            The Secretary shall prescribe such regulations as are 
        necessary or appropriate to carry out the purposes of this 
        subsection, including--
                (i) in the case of a defined benefit plan which provides 
            for unreduced benefits commencing before the social security 
            retirement age (as defined in section 415(b)(8)), rules 
            providing for the reduction of the maximum excess allowance 
            and the maximum offset allowance, and
                (ii) in the case of an employee covered by 2 or more 
            plans of the employer which fail to meet the requirements of 
            subsection (a)(4) (without regard to this subsection), rules 
            preventing the multiple use of the disparity permitted under 
            this subsection with respect to any employee.

        For purposes of clause (i), unreduced benefits shall not include 
        benefits for disability (within the meaning of section 223(d) of 
        the Social Security Act).

          (6) Special rule for plan maintained by railroads

        In determining whether a plan which includes employees of a 
    railroad employer who are entitled to benefits under the Railroad 
    Retirement Act of 1974 meets the requirements of this subsection, 
    rules similar to the rules set forth in this subsection shall apply. 
    Such rules shall take into account the employer-derived portion of 
    the employees' tier 2 railroad retirement benefits and any 
    supplemental annuity under the Railroad Retirement Act of 1974.

(m) Nondiscrimination test for matching contributions and employee 
        contributions

                           (1) In general

        A defined contribution plan shall be treated as meeting the 
    requirements of subsection (a)(4) with respect to the amount of any 
    matching contribution or employee contribution for any plan year 
    only if the contribution percentage requirement of paragraph (2) of 
    this subsection is met for such plan year.

                          (2) Requirements

        (A) Contribution percentage requirement

            A plan meets the contribution percentage requirement of this 
        paragraph for any plan year only if the contribution percentage 
        for eligible highly compensated employees for such plan year 
        does not exceed the greater of--
                (i) 125 percent of such percentage for all other 
            eligible employees for the preceding plan year, or
                (ii) the lesser of 200 percent of such percentage for 
            all other eligible employees for the preceding plan year, or 
            such percentage for all other eligible employees for the 
            preceding plan year plus 2 percentage points.

        This subparagraph may be applied by using the plan year rather 
        than the preceding plan year if the employer so elects, except 
        that if such an election is made, it may not be changed except 
        as provided by the Secretary.

        (B) Multiple plans treated as a single plan

            If two or more plans of an employer to which matching 
        contributions, employee contributions, or elective deferrals are 
        made are treated as one plan for purposes of section 410(b), 
        such plans shall be treated as one plan for purposes of this 
        subsection. If a highly compensated employee participates in two 
        or more plans of an employer to which contributions to which 
        this subsection applies are made, all such contributions shall 
        be aggregated for purposes of this subsection.

                     (3) Contribution percentage

        For purposes of paragraph (2), the contribution percentage for a 
    specified group of employees for a plan year shall be the average of 
    the ratios (calculated separately for each employee in such group) 
    of--
            (A) the sum of the matching contributions and employee 
        contributions paid under the plan on behalf of each such 
        employee for such plan year, to
            (B) the employee's compensation (within the meaning of 
        section 414(s)) for such plan year.

    Under regulations, an employer may elect to take into account (in 
    computing the contribution percentage) elective deferrals and 
    qualified nonelective contributions under the plan or any other plan 
    of the employer. If matching contributions are taken into account 
    for purposes of subsection (k)(3)(A)(ii) for any plan year, such 
    contributions shall not be taken into account under subparagraph (A) 
    for such year. Rules similar to the rules of subsection (k)(3)(E) 
    shall apply for purposes of this subsection.

                           (4) Definitions

        For purposes of this subsection--

        (A) Matching contribution

            The term ``matching contribution'' means--
                (i) any employer contribution made to a defined 
            contribution plan on behalf of an employee on account of an 
            employee contribution made by such employee, and
                (ii) any employer contribution made to a defined 
            contribution plan on behalf of an employee on account of an 
            employee's elective deferral.

        (B) Elective deferral

            The term ``elective deferral'' means any employer 
        contribution described in section 402(g)(3).

        (C) Qualified nonelective contributions

            The term ``qualified nonelective contribution'' means any 
        employer contribution (other than a matching contribution) with 
        respect to which--
                (i) the employee may not elect to have the contribution 
            paid to the employee in cash instead of being contributed to 
            the plan, and
                (ii) the requirements of subparagraphs (B) and (C) of 
            subsection (k)(2) are met.

               (5) Employees taken into consideration

        (A) In general

            Any employee who is eligible to make an employee 
        contribution (or, if the employer takes elective contributions 
        into account, elective contributions) or to receive a matching 
        contribution under the plan being tested under paragraph (1) 
        shall be considered an eligible employee for purposes of this 
        subsection.

        (B) Certain nonparticipants

            If an employee contribution is required as a condition of 
        participation in the plan, any employee who would be a 
        participant in the plan if such employee made such a 
        contribution shall be treated as an eligible employee on behalf 
        of whom no employer contributions are made.

        (C) Special rule for early participation

            If an employer elects to apply section 410(b)(4)(B) in 
        determining whether a plan meets the requirements of section 
        410(b), the employer may, in determining whether the plan meets 
        the requirements of paragraph (2), exclude from consideration 
        all eligible employees (other than highly compensated employees) 
        who have not met the minimum age and service requirements of 
        section 410(a)(1)(A).

    (6) Plan not disqualified if excess aggregate contributions 
                distributed before end of following plan year

        (A) In general

            A plan shall not be treated as failing to meet the 
        requirements of paragraph (1) for any plan year if, before the 
        close of the following plan year, the amount of the excess 
        aggregate contributions for such plan year (and any income 
        allocable to such contributions) is distributed (or, if 
        forfeitable, is forfeited). Such contributions (and such income) 
        may be distributed without regard to any other provision of law.

        (B) Excess aggregate contributions

            For purposes of subparagraph (A), the term ``excess 
        aggregate contributions'' means, with respect to any plan year, 
        the excess of--
                (i) the aggregate amount of the matching contributions 
            and employee contributions (and any qualified nonelective 
            contribution or elective contribution taken into account in 
            computing the contribution percentage) actually made on 
            behalf of highly compensated employees for such plan year, 
            over
                (ii) the maximum amount of such contributions permitted 
            under the limitations of paragraph (2)(A) (determined by 
            reducing contributions made on behalf of highly compensated 
            employees in order of their contribution percentages 
            beginning with the highest of such percentages).

        (C) Method of distributing excess aggregate contributions

            Any distribution of the excess aggregate contributions for 
        any plan year shall be made to highly compensated employees on 
        the basis of the amount of contributions on behalf of, or by, 
        each such employee. Forfeitures of excess aggregate 
        contributions may not be allocated to participants whose 
        contributions are reduced under this paragraph.

        (D) Coordination with subsection (k) and 402(g)

            The determination of the amount of excess aggregate 
        contributions with respect to a plan shall be made after--
                (i) first determining the excess deferrals (within the 
            meaning of section 402(g)), and
                (ii) then determining the excess contributions under 
            subsection (k).

                   (7) Treatment of distributions

        (A) Additional tax of section 72(t) not applicable

            No tax shall be imposed under section 72(t) on any amount 
        required to be distributed under paragraph (6).

        (B) Exclusion of employee contributions

            Any distribution attributable to employee contributions 
        shall not be included in gross income except to the extent 
        attributable to income on such contributions.

                   (8) Highly compensated employee

        For purposes of this subsection, the term ``highly compensated 
    employee'' has the meaning given to such term by section 414(q).

                           (9) Regulations

        The Secretary shall prescribe such regulations as may be 
    necessary to carry out the purposes of this subsection and 
    subsection (k), including regulations permitting appropriate 
    aggregation of plans and contributions.

             (10) Alternative method of satisfying tests

        A defined contribution plan shall be treated as meeting the 
    requirements of paragraph (2) with respect to matching contributions 
    if the plan--
            (A) meets the contribution requirements of subparagraph (B) 
        of subsection (k)(11),
            (B) meets the exclusive plan requirements of subsection 
        (k)(11)(C), and
            (C) meets the vesting requirements of section 408(p)(3).

       (11) Additional alternative method of satisfying tests

        (A) In general

            A defined contribution plan shall be treated as meeting the 
        requirements of paragraph (2) with respect to matching 
        contributions if the plan--
                (i) meets the contribution requirements of subparagraph 
            (B) or (C) of subsection (k)(12),
                (ii) meets the notice requirements of subsection 
            (k)(12)(D), and
                (iii) meets the requirements of subparagraph (B).

        (B) Limitation on matching contributions

            The requirements of this subparagraph are met if--
                (i) matching contributions on behalf of any employee may 
            not be made with respect to an employee's contributions or 
            elective deferrals in excess of 6 percent of the employee's 
            compensation,
                (ii) the rate of an employer's matching contribution 
            does not increase as the rate of an employee's contributions 
            or elective deferrals increase, and
                (iii) the matching contribution with respect to any 
            highly compensated employee at any rate of an employee 
            contribution or rate of elective deferral is not greater 
            than that with respect to an employee who is not a highly 
            compensated employee.

                        (12) Cross reference

            For excise tax on certain excess contributions, see section 
        4979.

(n) Coordination with qualified domestic relations orders

    The Secretary shall prescribe such rules or regulations as may be 
necessary to coordinate the requirements of subsection (a)(13)(B) and 
section 414(p) (and the regulations issued by the Secretary of Labor 
thereunder) with the other provisions of this chapter.

(o) Cross reference

            For exemption from tax of a trust qualified under this 
        section, see section 501(a).
