A right to an accrued benefit derived from employer contributions under a multiemployer plan shall not be treated as forfeitable solely because the plan provides that benefits accrued as a result of service with the participant’s employer before the employer had an obligation to contribute under the plan may not be payable if the employer ceases contributions to the multiemployer plan.
A matching contribution (within the meaning of section 401(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 section 401(k)(8)(B), an excess deferral under section 402(g)(2)(A), a permissible withdrawal under section 414(w), or an excess aggregate contribution under section 401(m)(6)(B).
For purposes of this subsection, except as provided in subparagraph (C), the term “year of service” means a calendar year, plan year, or other 12-consecutive month period designated by the plan (and not prohibited under regulations prescribed by the Secretary of Labor) during which the participant has completed 1,000 hours of service.

For purposes of paragraph (4), in the case of any participant in a defined contribution plan, or an insured defined benefit plan which satisfies the requirements of subsection (b)(1)(F), who has 5 consecutive 1-year breaks in service, years of service after such 5-year period shall not be required to be taken into account for purposes of determining the nonforfeitable percentage of his accrued benefit derived from employer contributions which accrued before such 5-year period.
If any years of service are not required to be taken into account by reason of a period of breaks in service to which clause (i) applies, such years of service shall not be taken into account in applying clause (i) to a subsequent period of breaks in service.
For purposes of clause (i), the term “nonvested participant” means a participant who does not have any nonforfeitable right under the plan to an accrued benefit derived from employer contributions.
For purposes of this subparagraph, the term “year” means the period used in computations pursuant to paragraph (5).
A plan amendment changing any vesting schedule under the plan shall be treated as not satisfying the requirements of paragraph (2) if the nonforfeitable percentage of the accrued benefit derived from employer contributions (determined as of the later of the date such amendment is adopted, or the date such amendment becomes effective) of any employee who is a participant in the plan is less than such nonforfeitable percentage computed under the plan without regard to such amendment.
A plan amendment changing any vesting schedule under the plan shall be treated as not satisfying the requirements of paragraph (2) unless each participant having not less than 3 years of service is permitted to elect, within a reasonable period after the adoption of such amendment, to have his nonforfeitable percentage computed under the plan without regard to such amendment.
If the present value of any nonforfeitable accrued benefit exceeds $7,000, a plan meets the requirements of this paragraph only if such plan provides that such benefit may not be immediately distributed without the consent of the participant.

The term “applicable defined benefit plan” means a defined benefit plan under which the accrued benefit (or any portion thereof) is calculated as the balance of a hypothetical account maintained for the participant or as an accumulated percentage of the participant’s final average compensation.
The Secretary shall issue regulations which include in the definition of an applicable defined benefit plan any defined benefit plan (or any portion of such a plan) which has an effect similar to an applicable defined benefit plan.
A defined benefits plan satisfies the requirements of this paragraph if the accrued benefit to which any participant is entitled upon his separation from the service is not less than a fraction of the annual benefit commencing at normal retirement age to which he would be entitled under the plan as in effect on the date of his separation if he continued to earn annually until normal retirement age the same rate of compensation upon which his normal retirement benefit would be computed under the plan, determined as if he had attained normal retirement age on the date on which any such determination is made (but taking into account no more than the 10 years of service immediately preceding his separation from service). Such fraction shall be a fraction, not exceeding 1, the numerator of which is the total number of his years of participation in the plan (as of the date of his separation from the service) and the denominator of which is the total number of years he would have participated in the plan if he separated from the service at the normal retirement age. For purposes of this subparagraph, social security benefits and all other relevant factors used to compute benefits shall be treated as remaining constant as of the current year for all years after such current year.
Notwithstanding subparagraphs (A), (B), and (C) of this paragraph, a plan shall not be treated as not satisfying the requirements of this paragraph solely because the accrual of benefits under the plan does not become effective until the employee has two continuous years of service. For purposes of this subparagraph, the term “years of service” has the meaning provided by section 410(a)(3)(A).
Notwithstanding the preceding subparagraphs, a defined benefit plan shall be treated as not satisfying the requirements of this paragraph if, under the plan, an employee’s benefit accrual is ceased, or the rate of an employee’s benefit accrual is reduced, because of the attainment of any age.
A plan shall not be treated as failing to meet the requirements of this subparagraph solely because the plan imposes (without regard to age) a limitation on the amount of benefits that the plan provides or a limitation on the number of years of service or years of participation which are taken into account for purposes of determining benefit accrual under the plan.
A plan shall not be treated as failing to meet the requirements of clause (i) solely because the subsidized portion of any early retirement benefit is disregarded in determining benefit accruals.
The Secretary shall provide by regulation for the coordination of the requirements of this subparagraph with the requirements of subsection (a), sections 404, 410, and 415, and the provisions of this subchapter precluding discrimination in favor of highly compensated employees.
A defined contribution plan satisfies the requirements of this paragraph if, under the plan, allocations to the employee’s account are not ceased, and the rate at which amounts are allocated to the employee’s account is not reduced, because of the attainment of any age.
The Secretary shall provide by regulation for the application of the requirements of this paragraph to target benefit plans.
The Secretary may provide by regulation for the coordination of the requirements of this paragraph with the requirements of subsection (a), sections 404, 410, and 415, and the provisions of this subchapter precluding discrimination in favor of highly compensated employees.
For purposes of determining an employee’s accrued benefit, the term “year of participation” means a period of service (beginning at the earliest date on which the employee is a participant in the plan and which is included in a period of service required to be taken into account under section 410(a)(5), determined without regard to section 410(a)(5)(E)) as determined under regulations prescribed by the Secretary of Labor which provide for the calculation of such period on any reasonable and consistent basis.
For purposes of this paragraph, except as provided in subparagraph (C), in the case of any employee whose customary employment is less than full time, the calculation of such employee’s service on any basis which provides less than a ratable portion of the accrued benefit to which he would be entitled under the plan if his customary employment were full time shall not be treated as made on a reasonable and consistent basis.
For purposes of this paragraph, in the case of any employee whose service is less than 1,000 hours during any calendar year, plan year or other 12-consecutive month period designated by the plan (and not prohibited under regulations prescribed by the Secretary of Labor) the calculation of his period of service shall not be treated as not made on a reasonable and consistent basis solely because such service is not taken into account.
In the case of any seasonal industry where the customary period of employment is less than 1,000 hours during a calendar year, the term “year of participation” shall be such period as determined under regulations prescribed by the Secretary of Labor.
For purposes of this subsection, in the case of any maritime industry, 125 days of service shall be treated as a year of participation. The Secretary of Labor may prescribe regulations to carry out the purposes of this subparagraph.
A plan shall not be treated as failing to meet the requirements of paragraph (1)(H)(i) if a participant’s accrued benefit, as determined as of any date under the terms of the plan, would be equal to or greater than that of any similarly situated, younger individual who is or could be a participant.
For purposes of this subparagraph, a participant is similarly situated to any other individual if such participant is identical to such other individual in every respect (including period of service, compensation, position, date of hire, work history, and any other respect) except for age.
In determining the accrued benefit as of any date for purposes of this subparagraph, the subsidized portion of any early retirement benefit or retirement-type subsidy shall be disregarded.
For purposes of this subparagraph, the accrued benefit may, under the terms of the plan, be expressed as an annuity payable at normal retirement age, the balance of a hypothetical account, or the current value of the accumulated percentage of the employee’s final average compensation.
An applicable defined benefit plan shall be treated as failing to meet the requirements of paragraph (1)(H) unless the terms of the plan provide that any interest credit (or an equivalent amount) for any plan year shall be at a rate which is not greater than a market rate of return. A plan shall not be treated as failing to meet the requirements of this subclause merely because the plan provides for a reasonable minimum guaranteed rate of return or for a rate of return that is equal to the greater of a fixed or variable rate of return.
An applicable defined benefit plan shall be treated as failing to meet the requirements of paragraph (1)(H) unless the plan provides that an interest credit (or equivalent amount) of less than zero shall in no event result in the account balance or similar amount being less than the aggregate amount of contributions credited to the account.
The Secretary may provide by regulation for rules governing the calculation of a market rate of return for purposes of subclause (I) and for permissible methods of crediting interest to the account (including fixed or variable interest rates) resulting in effective rates of return meeting the requirements of subclause (I).
If, after June 29, 2005, an applicable plan amendment is adopted, the plan shall be treated as failing to meet the requirements of paragraph (1)(H) unless the requirements of clause (iii) are met with respect to each individual who was a participant in the plan immediately before the adoption of the amendment.
For purposes of clause (iii)(I), the plan shall credit the accumulation account or similar amount 11 So in original. Probably should be “similar account”. with the amount of any early retirement benefit or retirement-type subsidy for the plan year in which the participant retires if, as of such time, the participant has met the age, years of service, and other requirements under the plan for entitlement to such benefit or subsidy.
The term “applicable plan amendment” means an amendment to a defined benefit plan which has the effect of converting the plan to an applicable defined benefit plan.
If the benefits of 2 or more defined benefit plans established or maintained by an employer are coordinated in such a manner as to have the effect of the adoption of an amendment described in subclause (I), the sponsor of the defined benefit plan or plans providing for such coordination shall be treated as having adopted such a plan amendment as of the date such coordination begins.
The Secretary shall issue regulations to prevent the avoidance of the purposes of this subparagraph through the use of 2 or more plan amendments rather than a single amendment.
For purposes of this subparagraph, the term “applicable defined benefit plan” has the meaning given such term by section 411(a)(13).

For purposes of this subparagraph, the term “indexing” means, in connection with an accrued benefit, the periodic adjustment of the accrued benefit by means of the application of a recognized investment index or methodology.
For purposes of this paragraph, the terms “early retirement benefit” and “retirement-type subsidy” have the meaning given such terms in subsection (d)(6)(B)(i).
For purposes of this paragraph, any reference to the accrued benefit shall be a reference to such benefit accrued to date.
For purposes of subparagraphs (A), (B), and (C) of paragraph (1), in the case of an applicable defined benefit plan (as defined in subsection (a)(13)(C)) which provides variable interest crediting rates, the interest crediting rate which is treated as in effect and as the projected interest crediting rate shall be a reasonable projection of such variable interest crediting rate, not to exceed 6 percent.
For purposes of this section, an employee’s accrued benefit derived from employer contributions as of any applicable date is the excess, if any, of the accrued benefit for such employee as of such applicable date over the accrued benefit derived from contributions made by such employee as of such date.
In the case of a defined benefit plan, the accrued benefit derived from contributions made by an employee as of any applicable date is the amount equal to the employee’s accumulated contributions expressed as an annual benefit commencing at normal retirement age, using an interest rate which would be used under the plan under section 417(e)(3) (as of the determination date).
The Secretary is authorized to adjust by regulation the conversion factor described in subparagraph (B) from time to time as he may deem necessary. No such adjustment shall be effective for a plan year beginning before the expiration of 1 year after such adjustment is determined and published.
For purposes of this section, in the case of any defined benefit plan, if an employee’s accrued benefit is to be determined as an amount other than an annual benefit commencing at normal retirement age, or if the accrued benefit derived from contributions made by an employee is to be determined with respect to a benefit other than an annual benefit in the form of a single life annuity (without ancillary benefits) commencing at normal retirement age, the employee’s accrued benefit, or the accrued benefits derived from contributions made by an employee, as the case may be, shall be the actuarial equivalent of such benefit or amount determined under paragraph (1) or (2).
Subsection (a) shall not apply to benefits which may not be provided for designated employees in the event of early termination of the plan under provisions of the plan adopted pursuant to regulations prescribed by the Secretary to preclude the discrimination prohibited by section 401(a)(4).
In the case of a defined benefit plan which permits voluntary employee contributions, the portion of an employee’s accrued benefit derived from such contributions shall be treated as an accrued benefit derived from employee contributions under a plan other than a defined benefit plan.
A plan shall be treated as not satisfying the requirements of this section if the accrued benefit of a participant is decreased by an amendment of the plan, other than an amendment described in section 412(d)(2), or section 4281 of the Employee Retirement Income Security Act of 1974.
Clause (i) shall apply to plan mergers and other transactions having the effect of a direct transfer, including consolidations of benefits attributable to different employers within a multiple employer plan.
Notwithstanding subsection (a)(8), an applicable plan shall not be treated as failing to meet any requirement of this subchapter, or as failing to have a uniform normal retirement age for purposes of this subchapter, solely because the plan provides for a normal retirement age described in paragraph (2).
Subject to subparagraph (C), if, after December 8, 2014, an applicable plan is amended to expand the application of the normal retirement age described in subparagraph (A) to additional participants or to employees of additional employers maintaining the plan, such plan shall also be treated as an applicable plan with respect to such participants or employees.
