Title 26

SECTION 1.411(a)-5

1.411(a)-5 Service included in determination of nonforfeitable percentage.

§ 1.411(a)-5 Service included in determination of nonforfeitable percentage.

(a) In general. Under section 411(a)(4), for purposes of determining the nonforfeitable percentage of an employee's right to his employer-derived accrued benefit under section 411(a)(2) and § 1.411(a)-3, all of an employee's years of service with an employer or employers maintaining the plan shall be taken into account except that years of service described in paragraph (b) of this section may be disregarded.

(b) Certain service. For purposes of paragraph (a) of this section, the following years of service may be disregarded:

(1) Service before age 22. (i) In the case of a plan which satisfies the requirements of section 411(a)(2) (A) or (B) (relating to 10-year vesting and 5-15-year vesting, respectively), a year of service completed by an employee before he attains age 22.

(ii) In the case of a plan which does not satisfy the requirements of section 411(a)(2) (A) or (B), a year of service completed by an employee before he attains age 22 if the employee is not a participant (for purposes of section 410) in the plan at any time during such year.

(iii) For purposes of this subparagraph in the case of a plan utilizing computation periods, service during a computation period described in section 411(a)(5)(A) within which the employee attains age 22 may not be disregarded. In the case of a plan utilizing the elapsed time method described in § 1.410(a)-7, service on or after the date on which the employee attains age 22 may not be disregarded.

(2) Contributory plans. In the case of a plan utilizing computation periods, a year of service completed by an employee under a plan which requires mandatory contributions (within the meaning of section 411(c)(2)(C) and § 1.411(c)-1(c)(4)) to be made by the employee for such year, if the employee does not participate for such year solely because of his failure to make all mandatory contributions to the plan for such year. If the employee contributes any part of the mandatory contributions for the year, such year may not be excluded by reason of this subparagraph. In the case of a plan utilizing the elapsed time method described in § 1.410(a)-7, the service which may be disregarded is the period with respect to which the mandatory contribution is not made.

(3) Plan not maintained - (i) In general. An employee's years of service with an employer during any period for which the employer did not maintain the plan or a predecessor plan may be disregarded for purposes of section 411(a)(2). Paragraph (b)(3)(ii) of this section provides rules regarding the period prior to the adoption of a plan. Paragraph (b)(3)(iii) of this section provides rules regarding the period after the termination of a plan. Paragraph (b)(3)(iv) of this section provides rules regarding employers who have certain relationships with other employers maintaining the plan.

(ii) Period prior to adoption. The period for which a plan is not maintained by an employer includes the period before the plan was established. For purposes of this subdivision, a plan is established on the first day of the plan year in which the plan is adopted even though the plan is adopted after such first day. Except as provided in paragraph (b)(3)(iv) of this section if an employer adopts a plan which has previously been established by another employer or group of employers, the plan is not maintained by the adopting employer prior to the first day of the plan year in which the plan is adopted by the adopting employer. In the case of a transfer of assets or liabilities (including a merger or consolidation) involving two plans maintained by a single employer, the successor (or transferee) plan is treated as if it was established at the same time as the date of the establishment of the earliest component plan. In the case of a plan merger, consolidation, or transfer of plan assets or liabilities involving plans of two or more employers, the successor plan is treated as if it were established on each of the separate dates on which such component plan was established for the employees of each employer. Thus, for example, if employer A establishes a plan January 1, 1970, and employer B establishes a plan January 1, 1980, and the plans were subsequently merged, then the merged plan would be treated as if it were in existence on January 1, 1970, with respect to A's employees and as if it were in existence on January 1, 1980, with respect to B's employees.

(iii) Period after termination or withdrawal. The period for which a plan is not maintained by an employer includes the period after the plan is terminated. For purposes of this section, a plan is terminated at the date there is a termination of the plan within the meaning of section 411(d)(3)(A) and the regulations thereunder. Notwithstanding the preceding sentence, if contributions to or under a plan are made after termination, the plan is treated as being maintained until such contributions cease, whether or not accruals are made after such termination. If, after termination of a plan in circumstances under which the employer may be liable to the Pension Benefit Guaranty Corporation under section 4062 of the Act, employer contributions are made to or under the plan to fund benefits accrued at the time of termination, such contributions shall, for purposes of this paragraph, be deemed to be payments in satisfaction of employer liability to such Corporation rather than contributions to or under the plan. In the case of a plan maintained by more than one employer, the period for which the plan is not maintained by the withdrawing employer includes the period after the withdrawal from the plan.

(iv) Certain employers. For purposes of this subparagraph -

(A) Predecessor employers. Service with a predecessor employer who maintained the plan of the current employer is treated as service with such current employer (see section 414(a)(1) and the regulations thereunder), and certain service with a predecessor employer who did not maintain the plan of the current employer is treated as service with the current employer (see section 414(a)(2) and the regulations thereunder).

(B) Related employers. Service with an employer is treated as service for certain related employers for the period during which the employers are related. These related employers include members of a controlled group of corporations (within the meaning of section 1563(a), determined without regard to subsections (a)(4) and (e)(3) (C) thereof) and trades or businesses (whether or not incorporated) which are under common control (see section 414 (b) and (c) and 29 CFR Part 2530, Department of Labor regulations relating to minimum standards for employee pension benefits plans).

(C) Plan maintained by more than one employer. Service with an employer who maintains a plan is treated as service for each other employer who maintains that plan for the period during which the employers are maintaining the plan (see section 413 (b)(4) and (c)(3) and 29 CFR Part 2530, Department of Labor regulations relating to minimum standards for employee pension benefit plans).

(v) Predecessor plan - (A) General rule. In the case of an employee who was covered by a predecessor plan, the time the successor of such plan is maintained for such employee includes the time the predecessor plan was maintained if, as of the later of the time the predecessor plan is terminated or the successor plan is established, the employee's years of service under the predecessor plan are not equalled or exceeded by the aggregate number of consecutive 1-year breaks in service occuring after such years of service. Years of service and breaks in service, without regard to whether the employee has nonforfeitable rights under the predecessor plan, are determined under section 411(a) (5) and (6) except that years between the termination date of the predecessor plan and the date of establishment of the successor plan do not count as years of service.

(B) Definition of predecessor plan. For purposes of this section, if -

(1) An employer establishes a retirement plan (within the meaning of section 7476(d)) qualified under subchapter D of chapter 1 of the Code within the 5-year period immediately preceding or following the date another such plan terminates, and

(2) The other plan is terminated during a plan year to which this section applies.

The terminated plan is a predecessor plan with respect to such other plan.

Example.(1) Employer X's qualified plan A terminated on January 1, 1977, Employer X established qualified plan B on January 1, 1981. Under paragraph (b)(3)(v)(B) of this section, plan A is a predecessor plan with respect to plan B because plan B is established within the 5-year period immediately following the date plan A terminated.

(2) Employee C was not covered by the A plan. Under the general rule in subdivision (v)(A) of this subparagraph, plan B is not maintained until January 1, 1981, with respect to Employee C.

(3) Employee D was covered by the A plan. On December 31, 1976, D had 4 years of service. D had 4 consecutive 1-year breaks in service because, during the years between the termination of plan A and the establishment of plan B, he did not have more than 500 hours of service in any applicable computation period. Because D's consecutive 1-year breaks (4) equal his years of service prior to his breaks (4), plan B is not maintained until January 1, 1981, with respect to employee D.

(4) Employee E was covered by the A plan. On December 31, 1975, E had 6 years of service. E had a 1-year break in service in 1976. E also had 4 consecutive 1-year breaks in service for the period between plan A's termination and plan B's establishment. Because E's years of service (6) are not less than his consecutive 1-year breaks (5), plan B is maintained for E as of the establishment date of plan A.

(4) Break in service. A year of service which is not required to be taken into account by reason of a break in service (within the meaning of section 411(a)(6) and § 1.411(a)-6)).

(5) Service before January 1, 1971. A year of service completed by an employee prior to January 1, 1971, unless the employee completes at least 3 years of service at any time after December 31, 1970. For purposes of determining if an employee completes 3 years of service, whether or not consecutive, the exceptions of section 411(a)(4) are not applicable. For the meaning of the term “year of service”, see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(6) Service before effective date. A year of service completed before the first plan year for which this section applies to the plan, if such service would have been disregarded under the plan rules relating to breaks in service (whether or not such rules are so designated in the plan) as such rules were in effect from time to time under the plan. For this purpose, plan rules which result in the loss of prior vesting or benefit accruals of an employee, or which deny an employee eligibility to participate, by reason of separation or failure to complete a required period of service within a specified priod of time (e.g., 300 hours in one year) will be considered break in service rules.

(i) [Reserved]

(ii) Examples. The rules of this subparagraph are illustrated by the following examples:

Example 1.The A plan in 1971 provides for immediate participation and vesting at normal retirement age. Employees accrue a unit benefit based on their compensation in each year. The plan provides that if an employee is not employed on the last day of the calendar year, he loses all accrued benefits. The requirement of employment on the last day of the year is a break in service rule because employees can lose benefits by reason of their separation. Accordingly, in the case of employees who separate and do not return by the close of the year, service which is completed prior to separation may be disregarded. Example 2.The B plan in 1971 excludes from plan participation employees who work less than 1,200 hours per year. Because years of less than 1,200 hours are not taken into account under the B plan for eligibility to participate, such years are excluded under rules relating to breaks in service. Therefore, the years can be disregarded under this subparagraph. Example 3.The C plan in 1971 provides for immediate participation and provides accruals and vesting credit for 1,200 hours or more in a given year. The plan provides that if a participant works less than 300 hours in a given year, he loses all prior vesting and benefit credits. The 300 hour rule is a break in service rule because the failure to complete 300 hours results in the loss of vesting and prior service credit. The 1,200 hour requirement is not a break in service rule because even though employees do not increase vesting or accrue benefits for service between 300 and 1,200 hours, they cannot lose prior vesting or benefits for such service. Accordingly, the C plan can disregard completed years only on account of less than 300 hours of service by an employee.

(c) Special continuity rule for certain plans. For special rules for computing years of service in the case of a plan maintained by more than one employer, see 29 CFR Part 2530 (Department of Labor regulations relating to minimum standards for employee pension benefit plans).
