PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.411(a)-6  Year of service; hours of service; breaks in service.

    (a) Year of service. Under section 411 (a)(5)(A), for purposes of 
the regulations thereunder, the term ``year of service'' is defined in 
regulations prescribed by the Secretary of Labor under section 
203(b)(2)(A) of the Employee Retirement Income Security Act of 1974. For 
special rules applicable to seasonal industries and maritime industries, 
see regulations prescribed by the Secretary of Labor under subparagraphs 
(C) and (D) of section 203(b)(2) of the Employee Retirement Income 
Security Act of 1974.
    (b) Hours of service. Under section 411(a)(5)(B), for purposes of 
the regulations thereunder, the term ``hours of service'' has the 
meaning provided by section 410(a)(3)(C). See regulations prescribed by 
the Secretary of Labor under 29 CFR Part 2530, relating to minimum 
standards for employee pension benefit plans.
    (c) Breaks in service. Under section 411(a)(6), for purposes of 
Sec. 1.411(a)-5(b)(4) and of this paragraph--
    (1) In general--(i) Year of service after 1-year break in service. 
In the case of any employee who has incurred a 1-year break in service, 
years of service completed before such break are not required to be 
taken into account until the employee has completed one year of service 
after his return to service.
    (ii) Defined contribution plan. In the case of a participant in a 
defined contribution plan or in an insured defined benefit plan (which 
plan satisfies the

[[Page 594]]

requirements of section 411 (b)(1)(F) and Sec. 1.411(b)-1) who has 
incurred a 1-year break in service, years of service completed after 
such break are not required to be taken into account for purposes of 
determining the nonforfeitable percentage of the participant's right to 
employer-derived benefits which accrued before such break. This 
subdivision does not permit years of service completed before a 1-year 
break in service to be disregarded in determining the nonforfeitable 
percentage of a participant's right to employer-derived benefits which 
accrue after such break.
    (iii) Nonvested participants. In the case of an employee who is a 
nonvested participant in employer-derived benefits at the time he incurs 
a 1-year break in service, years of service completed by such 
participant before such break are not required to be taken into account 
for purposes of determining the nonforfeitable percentage of his right 
to employer-derived benefits if at such time the number of consecutive 
1-year breaks in service included in his most recent break in service 
equals or exceeds the aggregate number of his years of service, whether 
or not consecutive, completed before such break. In the case of a plan 
utilizing the elapsed time method described in Sec. 1.410(a)-7, the 
condition in the preceding sentence shall be satisfied if the period of 
severance is at least one year and the consecutive period of severance 
equals or exceeds his prior period of service, whether or not 
consecutive, completed before such period of severance. In computing the 
aggregate number of years of service prior to such break, years of 
service which could have been disregarded under this subdivision by 
reason of any prior break in service may be disregarded.
    (2) One-year break in service defined. The term ``1-year break in 
service'' means a calendar year, plan year, or other 12-consecutive 
month period designated by a plan (and not prohibited under regulations 
prescribed by the Secretary of Labor) during which the participant has 
not completed more than 500 hours of service. In the case of a plan 
utilizing the elapsed time method, the term ``1-year break in service'' 
means a 12-consecutive month period beginning on the severance from 
service date or any anniversary thereof and ending on the next 
succeeding anniversary of such date; provided, however, that the 
employee during such 12-consecutive-month period does not complete any 
hours of service within the meaning of 29 CFR Part 2530.200b-2(a) for 
the employer or employers maintaining the plan. See regulations 
prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to 
minimum standards for employee pension benefit plans.
    (d) Examples. The rules provided by this section are illustrated by 
the following examples:

    Example (1). (i) X Corporation maintains a defined contribution plan 
to which section 411 applies. The plan uses the calendar year as the 
vesting computation period. In 1980, Employee A, who was hired at age 
35, separates from the service of X Corporation after completing 4 years 
of service. At the time of his separation, Employee A had a 
nonforfeitable right to 25 percent of his employer-derived accrued 
benefit which was not distributed. In 1985, after incurring 5 
consecutive one-year breaks in service. Employee A is re-employed by X 
Corporation and becomes an active participant in the plan. The plan 
provides that, for 1985 and all subsequent years, Employee A's previous 
years of service will not be taken into account for purposes of 
computing the nonforfeitable percentage of his employer-derived accrued 
benefit, solely because of his break in service.
    (ii) The plan fails to satisfy section 411. Section 411(a)(6)(B) 
would permit the plan to disregard Employee A's prior service for 
purposes of computing his nonforfeitable percentage in 1985 only, but 
such service must be taken into account in subsequent years unless there 
is another break in service. Under section 411(a)(6)(C), the plan is not 
required to take Employee A's post-break service into account for 
purposes of computing his nonforfeitable right to his prebreak employer-
derived accrued benefits. This provision, however, would not permit the 
plan to disregard pre-break service in determining his nonforfeitable 
right to his benefit accrued after the break. The exception provided by 
section 411(a)(6)(D) does not apply in the case of a participant who has 
any nonforfeitable right to his accrued benefit derived from employer 
contributions.
    Example (2). (i) X Corporation maintains a qualified plan to which 
sections 410 and 411 (relating to minimum participation standards and 
minimum vesting standards, respectively) apply. The plan permits 
participation upon completion of a year of service and provides that 
100% of an employee's employer-

[[Page 595]]

derived accrued benefit vests after 10 years of service. The plan uses 
the calendar year as the vesting computation period. The plan provides 
that an employee who completes at least 1,000 hours of service in a 12-
month period is credited with a year of service for participation and 
vesting purposes. The plan also provides that an employee who does not 
complete more than 500 hours of service in that 12-month period incurs a 
one-year break in service. The plan includes the rule described in 
section 411 (a)(6)(D) for participation and vesting purposes. Under this 
rule, an employee's years of service prior to a break in service may be 
disregarded under certain circumstances if he has no vested right to any 
employer-derived benefit under the plan. The plan does not contain the 
rule described in section 411(a)(6)(B) (relating to the requirement of 
one year of service after a one-year break in service).
    (ii) Employee A commences employment with the X Corporation on 
January 1, 1977. Employee A's employment history for 1977 through 1989 
is as follows:

------------------------------------------------------------------------
                                                               Hours of
                  Year ending December 31                      service
                                                              completed
------------------------------------------------------------------------
1977.......................................................        1,000
1978.......................................................          800
1979.......................................................        1,000
1980.......................................................          400
1981.......................................................        1,000
1982.......................................................            0
1983.......................................................          400
1984.......................................................        1,000
1985.......................................................            0
1986.......................................................            0
1987.......................................................          500
1988.......................................................          200
1989.......................................................        1,000
------------------------------------------------------------------------


Employee A's status as a participant during this period is determined as 
follows:
    1978: Employee A was a plan participant on January 1, 1978, because 
he completed a year of service (1,000 hours) in 1977. He did not 
complete a year of service in 1978 because he completed fewer than 1,000 
hours in that year. Because he completed more than 500 hours of service 
in 1978, however, Employee A did not incur a one-year break in service 
that year.
    1979: Employee A completes a year of service in 1979. Because he did 
not incur a one-year break in service in 1978, the plan may not 
disregard his 1977 service for purposes of determining his years of 
service as of January 1, 1979.
    1980: Employee A incurs a one-year break in service in 1980.
    1981: Because Employee A had completed 2 years of service prior to 
1981 and had incurred one 1-year break in service prior to 1981, under 
section 411(a)(6)(D), the plan may not disregard his pre-1980 service in 
1981. Employee A completes a year of service in 1981.
    1982: Employee A incurs a one-year break in service in 1982.
    1983: Employee A incurs a one-year break in service in 1983. As of 
the end of 1983, he has completed 3 years of service and has incurred 2 
consecutive one-year breaks in service.
    1984: Employee A completes a year of service in 1984. Under section 
411(a)(6)(D), his pre-1982 service may not be disregarded in 1984 
because, as of the beginning of 1984, his pre-1984 years of service (3) 
exceed his consecutive one-year breaks in service (2).
    1984-1988: Employee A incurs 4 consecutive one-year breaks in 
service during the years 1985 through 1988.
    1989: Employee A's pre-1989 service is disregarded in 1989 and all 
subsequent plan years because his years of service as of January 1, 
1989, equal the number of consecutive one-year breaks he has incurred as 
of that date. Therefore, as of the beginning of 1989, Employee A is not 
a plan participant. Employee A completes a year of service in 1989. 
(Although section 411(a)(6)(D) does not prohibit the plan provision 
under which Employee A's pre-1989 service is disregarded, that section 
does not require such a provision in a qualified plan.)
