§ 1.411(a)-3T Vesting in employer-derived benefits (temporary).

(a) In general—(1) [Reserved]

(2) Composite arrangements. A plan will not be considered to satisfy the requirements of paragraph (b), (c), or (d) of this section unless it satisfies all requirements of a particular one of such paragraphs with respect to all of an employee's years of service. A plan which, for example, satisfies the requirements of paragraph (b) (but not (c) or (d)) for an employee's first 4 years of service and satisfies the requirements of paragraph (c) (but not (b)) for all of his remaining years of service does not satisfy the requirements of this section. A plan is not precluded from satisfying the requirements of one such paragraph with respect to one group of employees and another such paragraph with respect to another group provided that the groups are not so structured as to evade the requirements of this paragraph.

(b) 5-year vesting. A plan satisfies the requirements of section 411(a)(2)(A) and this paragraph if an employee who has completed 5 years of service has a nonforfeitable right to 100 percent of his or her accrued benefits derived from employer contributions.

(c) 3- to 7-year vesting. A plan satisfies the requirements of section 411(a)(2)(B) and this paragraph if an employee who has completed at least 3 years of service has a nonforfeitable right to a percentage of his accrued benefit derived from employer contributions, which percentage is not less than the nonforfeitable percentage determined under the following table:

Completed years of service	Nonforfeitable percentage
3	20
4	40
5	60
6	80
7 or more	100

(d) Multiemployer plans. A plan satisfies the requirements of section 411(a)(2)(C) and this paragraph if—

(1) The plan is a multiemployer plan (within the meaning of section 414(f)), and

(2) Under the plan—

(i) An employee who is covered pursuant to a collective bargaining agreement described in section 414(f)(1)(B) has a nonforfeitable right to 100 percent of the employee's accrued benefit derived from employer contributions not later than upon completion of 10 years of service, and

(ii) The requirements of paragraph (b) or (c) of this section are met with respect to employees who are not covered pursuant to a collective bargaining agreement described in section 414(f)(1)(B).

(iii) For purposes of this provision, an employee is not covered pursuant to a collective bargaining agreement unless the employee is represented by a bona fide employee representative that is a party to the collective bargaining agreement pursuant to which the multiemployer plan is maintained. Thus, for example, an employee of either the multiemployer plan or the employee representative is not covered pursuant to the collective bargaining agreement under which the plan is maintained even if the employee is covered pursuant to an agreement entered into by the multiemployer plan or employee representative on behalf of the employee and even if all such employees covered under the plan constitute only a de minimis percentage of the total employees covered under the plan.

(e) Effective date. (1) The provisions of this section apply to all employees who have one hour of service in any plan year beginning after—

(i) December 31, 1988, or

(ii) In the case of a plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified before March 1, 1986, for employees covered by any such agreement, the earlier of—

(A) The later of—

(1) January 1, 1989, or

(2) The date on which the last of such collective bargaining agreements terminates (determined without regard to any extension thereof after February 28, 1986), or

(B) January 1, 1991.

(2) For employees not described in paragraph (e)(1), above, the regulations in effect prior to January 1, 1989, shall be applied to determine the requirements of this section.

(f) Examples. The rules provided by this section are illustrated by the following examples:

Example 1.Plan B provides that each employee's rights to his employer-derived accrued benefit are nonforfeitable as follows:

Completed years of service	Nonforfeitable percentage
1	0
2	10
3	25
4	45
5	65
6	75
7	100

Plan B does not satisfy the requirements of paragraph (c) of this section (relating to 3- to 7-year vesting) because the nonforfeitable percentage provided by the plan after completion of 6 years of service (75 percent) is less than the percentage required by paragraph (c) of this section at that time (80 percent). The fact that the nonforfeitable percentage provided by the plan for years prior to the 6th year of service is greater than the percentage required under paragraph (c) of this section is immaterial. The plan fails to satisfy the requirements of paragraph (c) of this section even if it is demonstrated that the value of the vesting provided by the plan to the employees is at least equal to the value of the vesting rate required by this paragraph. Example 2.Plan C provides for plan participation after the completion of 1 year of service. The plan provides that each employee's rights to his employer-derived accrued benefits are 100 percent nonforfeitable after 5 years of plan participation rather than service. The plan does not satisfy the requirements of paragraph (b) of this section because, under the plan, an employee obtains a 100 percent nonforfeitable right to his or her employer-derived accrued benefit only after completion of more than 5 years of service. Example 3.Plan D provides that each employee's rights to his employer-derived accrued benefits are nonforfeitable in accordance with the following schedule:

Completed years of service	Nonforfeitable percentage
0 to 4	0
5	60
6	80
7	100

The plan does not satisfy the requirements of paragraph (b) of this section after the 4th year of service. It does not satisfy the requirements of paragraph (c) of this section for years prior to the 5th year of service. The plan does not satisfy the requirements of this section because it does not satisfy the requirements of a particular one of the two paragraphs for each of an employee's years of service. Example 4.Plan G provides that each employee's rights to his employer-derived accrued benefit are 100 percent nonforfeitable upon completion of 3 years of service. The plan satisfies the requirements of paragraphs (b) and (c) of this section and, because it satisfies the requirements of at least one of such paragraphs for all of an employee's years of service, it satisfies the requirements of this section.
