Sec. 1.401(a)(4)-12  Definitions.

    Unless otherwise provided, the definitions in this section govern in 
applying the provisions of Sec. Sec. 1.401(a)(4)-1 through 1.401(a)(4)-
13.
    Accumulation plan. Accumulation plan means a defined benefit plan 
under which the benefit of every employee for each plan year is 
separately determined, using plan year compensation (if benefits are 
determined as a percentage of compensation rather as than a dollar 
amount) separately calculated for the plan year, and each employee's 
total accrued benefit as of the end of a plan year is the sum of the 
separately determined benefit for that plan year and the total accrued 
benefit as of the end of the preceding plan year.
    Acquired group of employees. Acquired group of employees means 
employees of a prior employer who become employed by the employer in a 
transaction between the employer and the prior employer that is a stock 
or asset acquisition, merger, or other similar transaction involving a 
change in the employer of the employees of a trade or business, plus 
employees hired by or transferred into the acquired trade or business on 
or before a date selected by the employer that is within the transition 
period defined in section 410(b)(6)(C)(ii). In addition, in the case of 
a transaction prior to the effective date of these regulations, the date 
by

[[Page 176]]

which employees must be hired by or transferred into the acquired trade 
or business in order to be included in the acquired group of employees 
may be any date prior to February 11, 1993, without regard to whether it 
is later than the end of the transition period defined in section 
410(b)(6)(C)(ii).
    Actuarial equivalent. An amount or benefit is the actuarial 
equivalent of, or is actuarially equivalent to, another amount or 
benefit at a given time if the actuarial present value of the two 
amounts or benefits (calculated using the same actuarial assumptions) at 
that time is the same.
    Actuarial present value. Actuarial present value means the value as 
of a specified date of an amount or series of amounts due thereafter, 
where each amount is--
    (1) Multiplied by the probability that the condition or conditions 
on which payment of the amount is contingent will be satisfied; and
    (2) Discounted according to an assumed rate of interest to reflect 
the time value of money.
    Ancillary benefit. Ancillary benefit is defined in Sec. 
1.401(a)(4)-4(e)(2).
    Average annual compensation. Average annual compensation is defined 
in Sec. 1.401(a)(4)-3(e)(2).
    Base benefit percentage. Base benefit percentage is defined in Sec. 
1.401(l)-1(c)(3).
    Benefit formula. Benefit formula means the formula a defined benefit 
plan applies to determine the accrued benefit (within the meaning of 
section 411(a)(7)(A)(i)) in the form of an annual benefit commencing at 
normal retirement age of an employee who continues in service until 
normal retirement age. Thus, for example, the benefit formula does not 
include the accrual method the plan applies (in conjunction with the 
benefit formula) to determine the accrued benefit of an employee who 
terminates employment before normal retirement age. For purposes of this 
definition, a change in plan provisions that applies only to certain 
employees who terminate within a limited period of time (e.g., an early 
retirement window benefit) is treated as a change in the plan's benefit 
formula for the employees to whom the change is potentially applicable 
during the period that the change is potentially applicable to them. The 
preceding sentence applies only to the extent that the change in plan 
provisions would result in a change in the benefit formula if it were 
permanent and applied without regard to when the employees' employment 
was terminated.
    Benefit, right, or feature. Benefit, right, or feature means an 
optional form of benefit, an ancillary benefit, or an other right or 
feature within the meaning of Sec. 1.401(a)(4)-4(e).
    Contributory DB plan. Contributory DB plan means a defined benefit 
plan that includes employee contributions not allocated to separate 
accounts.
    Defined benefit excess plan. Defined benefit excess plan is defined 
in Sec. 1.401(l)-1(c)(16)(i).
    Defined benefit plan. Defined benefit plan is defined in Sec. 
1.410(b)-9.
    Defined contribution plan. Defined contribution plan is defined in 
Sec. 1.410(b)-9.
    Determination date. Determination date is defined in Sec. 
1.401(a)(4)-8(b)(3)(iv)(A).
    Employee. With respect to a plan for a given plan year, employee 
means an employee (within the meaning of Sec. 1.410(b)-9) who benefits 
as an employee under the plan for the plan year (within the meaning of 
Sec. 1.410(b)-3).
    Employer. Employer is defined in Sec. 1.410(b)-9.
    ESOP. ESOP is defined in Sec. 1.410(b)-9.
    Excess benefit percentage. Excess benefit percentage is defined in 
Sec. 1.401(l)-1(c)(14).
    Former employee. With respect to a plan for a given plan year, 
former employee means a former employee (within the meaning of Sec. 
1.410(b)-9).
    Former HCE. Former HCE means a highly compensated former employee as 
defined in Sec. 1.410(b)-9.
    Former NHCE. Former NHCE means a former employee who is not a former 
HCE.
    Fresh-start date. Fresh-start date is defined in Sec. 1.401(a)(4)-
13(c)(5)(iii).
    Fresh-start group. Fresh-start group is defined in Sec. 
1.401(a)(4)-13(c)(5)(ii).
    Gross benefit percentage. Gross benefit percentage is defined in 
Sec. 1.401(l)-1(c)(18).
    HCE. HCE means a highly compensated employee as defined in

[[Page 177]]

Sec. 1.410(b)-9 who benefits under the plan for the plan year (within 
the meaning of Sec. 1.410(b)-3).
    Integration level. Integration level is defined in Sec. 1.401(l)-
1(c)(20).
    Measurement period. Measurement period is defined in Sec. 
1.401(a)(4)-3(d)(1)(iii).
    Multiemployer plan. Multiemployer plan is defined in Sec. 1.410(b)-
9.
    NHCE. NHCE means an employee who is not an HCE.
    Nonexcludable employee. Nonexcludable employee means an employee 
within the meaning of Sec. 1.410(b)-9, other than an excludable 
employee with respect to the plan as determined under Sec. 1.410(b)-6. 
A nonexcludable employee may be either a highly or nonhighly compensated 
nonexcludable employee, depending on the nonexcludable employee's status 
under section 414(q).
    Normalize. With respect to a benefit payable to an employee in a 
particular form, normalize means to convert the benefit to an 
actuarially equivalent straight life annuity commencing at the 
employee's testing age. The actuarial assumptions used in normalizing a 
benefit must be reasonable and must be applied on a gender-neutral 
basis. A standard interest rate and a standard mortality table are among 
the assumptions considered reasonable for this purpose.
    Offset plan. Offset plan is defined in Sec. 1.401(l)-1(c)(24).
    Optional form of benefit. Optional form of benefit is defined in 
Sec. 1.401(a)(4)-4(e)(1).
    Other right or feature. Other right or feature is defined in Sec. 
1.401(a)(4)-4(e)(3).
    Plan. Plan means a plan within the meaning of Sec. 1.410(b)-7 (a) 
and (b), after application of the mandatory disaggregation rules of 
Sec. 1.410(b)-7(c) and the permissive aggregation rules of Sec. 
1.410(b)-7(d).
    Plan year. Plan year is defined in Sec. 1.410(b)-9.
    Plan year compensation--(1) In general. Plan year compensation means 
section 414(s) compensation for the plan year determined by measuring 
section 414(s) compensation during one of the periods described in 
paragraphs (2) through (4) of this definition. Whichever period is 
selected must be applied uniformly to determine the plan year 
compensation of every employee.
    (2) Plan year. This period consists of the plan year.
    (3) Twelve-month period ending in the plan year. This period 
consists of a specified 12-month period ending with or within the plan 
year, such as the calendar year or the period for determining benefit 
accruals described in Sec. 1.401(a)(4)-3(f)(6).
    (4) Period of plan participation during the plan year. This period 
consists of the portion of the plan year during which the employee is a 
participant in the plan. This period may be used to determine plan year 
compensation for the plan year in which participation begins, the plan 
year in which participation ends, or both. This period may be used to 
determine plan year compensation when substituted for average annual 
compensation in Sec. 1.401(a)(4)-3(e)(2)(ii)(A) only if the plan year 
is also the period for determining benefit accruals under the plan 
rather than another period as permitted under Sec. 1.401(a)(4)-3(f)(6). 
Further, selection of this period must be made on a reasonably 
consistent basis from plan year to plan year in a manner that does not 
discriminate in favor of HCEs.
    (5) Special rule for new employees. Notwithstanding the uniformity 
requirement of paragraph (1) of this definition, if employees' plan year 
compensation for a plan year is determined based on a 12-month period 
ending within the plan year under paragraph (3) of this definition, then 
the plan year compensation of any employees whose date of hire was less 
than 12 months before the end of that 12-month period must be determined 
uniformly based either on the plan year or on the employees' periods of 
participation during the plan year, as provided in paragraphs (2) and 
(4), respectively, of this definition.
    QJSA. QJSA means a qualified joint and survivor annuity as defined 
in section 417(b).
    QSUPP--(1) In general. QSUPP or qualified social security supplement 
means a social security supplement that meets each of the requirements 
in paragraphs (2) through (6) of this definition.
    (2) Accrual--(i) General rule. The amount of the social security 
supplement payable at any age for which the

[[Page 178]]

employee is eligible for the social security supplement must be equal to 
the lesser of--
    (A) The employee's old-age insurance benefit, unreduced on account 
of age, under title II of the Social Security Act; and
    (B) The accrued social security supplement, determined under one of 
the methods in paragraph (2) (ii) through (iv) of this definition.
    (ii) Section 401(l) plans. In the case of a section 401(l) plan that 
is a defined benefit excess plan, each employee's accrued social 
security supplement equals the employee's average annual compensation up 
to the integration level, multiplied by the disparity provided by the 
plan for the employee's years of service used in determining the 
employee's accrued benefit under the plan. In the case of a section 
401(l) plan that is an offset plan, each employee's accrued social 
security supplement equals the dollar amount of the offset accrued for 
the employee under the plan.
    (iii) PIA offset plan. In the case of a PIA offset plan, each 
employee's accrued social security supplement equals the dollar amount 
of the offset accrued for the employee under the plan. For this purpose, 
a PIA offset plan is a plan that reduces an employee's benefit by an 
offset based on a stated percentage of the employee's primary insurance 
amount under the Social Security Act.
    (iv) Other plans. In the case of any other plan, each employee's 
social security supplement accrues ratably over the period beginning 
with the later of the employee's commencement of participation in the 
plan or the effective date of the social security supplement and ending 
with the earliest age at which the social security supplement is payable 
to the employee. The effective date of the social security supplement is 
the later of the effective date of the amendment adding the social 
security supplement or the effective date of the amendment modifying an 
existing social security supplement to comply with the requirements of 
this definition. If, by the end of the first plan year to which these 
regulations apply, as set forth in Sec. 1.401(a)(4)-13 (a) and (b), an 
amendment is made to a social security supplement in existence on 
September 19, 1991, the employer may treat the accrued portion of the 
social security supplement, as determined under the plan without regard 
to amendments made after September 19, 1991, as included in the 
employee's accrued social security supplement, provided that the 
remainder of the social security supplement is accrued under the 
otherwise-applicable method.
    (3) Vesting. The plan must provide that an employee's right to the 
accrued social security supplement becomes nonforfeitable within the 
meaning of section 411 as if it were an early retirement benefit.
    (4) Eligibility. The plan must impose the same eligibility 
conditions on receipt of the social security supplement as on receipt of 
the early retirement benefit in conjunction with which the social 
security supplement is payable. Furthermore, if the service required for 
an employee to become eligible for the social security supplement 
exceeds 15 years, then the ratio percentage of the group of employees 
who actually satisfy the eligibility conditions on receipt of the QSUPP 
in the current plan year must equal or exceed the unsafe harbor 
percentage applicable to the plan under Sec. 1.410(b)-4(c)(4)(ii).
    (5) QJSA. At each age, the most valuable QSUPP commencing at that 
age must be payable in conjunction with the QJSA commencing at that age. 
In addition, the plan must provide that, in the case of a social 
security supplement payable in conjunction with a QJSA, the social 
security supplement will be paid after the employee's death on the same 
terms as the QJSA, but in no event for a period longer than the period 
for which the social security supplement would have been paid to the 
employee had the employee not died. For example, if the QJSA is in the 
form of a joint annuity with a 50-percent survivor's benefit, the social 
security supplement must provide a 50-percent survivor's benefit. When 
section 417(c) requires the determination of a QJSA for purposes of 
determining a qualified pre-retirement survivor's annuity as defined in 
section 417(c) (QPSA), the social security supplement payable in 
conjunction with that QJSA

[[Page 179]]

must be paid in conjunction with the QPSA.
    (6) Protection. The plan must specifically provide that the social 
security supplement is treated as an early retirement benefit that is 
protected under section 411(d)(6) (other than for purposes of sections 
401(a)(11) and 417). Thus, the accrued social security supplement must 
continue to be payable notwithstanding subsequent amendment of the plan 
(including the plan's termination), and an employee may meet the 
eligibility requirements for the social security supplement after plan 
termination.
    Qualified plan. Qualified plan means a plan that satisfies section 
401(a). For this purpose, a qualified plan includes an annuity plan 
described in section 403(a).
    Rate group. Rate group is defined in Sec. 1.401(a)(4)-2(c)(1) or is 
defined in Sec. 1.401(a)(4)-3(c)(1).
    Ratio percentage. Ratio percentage is defined in Sec. 1.410(b)-9.
    Section 401(a)(17) employee. Section 401(a)(17) employee is defined 
in Sec. 1.401(a)(17)-1(e)(2)(ii).
    Section 401(k) plan. Section 401(k) plan is defined in Sec. 
1.410(b)-9.
    Section 401(l) plan. Section 401(l) plan is defined in Sec. 
1.410(b)-9.
    Section 401(m) plan. Section 401(m) plan is defined in Sec. 
1.410(b)-9.
    Section 414(s) compensation--(1) General rule. When used with 
reference to compensation for a plan year, 12-month period, or other 
specified period, section 414(s) compensation means compensation 
measured using an underlying definition that satisfies section 414(s) 
for the applicable plan year. Whether an underlying definition of 
compensation satisfies section 414(s) is determined on a year-by-year 
basis, based on the provisions of section 414(s) in effect for the 
applicable plan year and, if relevant, the employer's HCEs and NHCEs for 
that plan year. See Sec. 1.414(s)-1(i) for transition rules for plan 
years beginning before the effective date applicable to the plan under 
Sec. 1.401(a)(4)-13 (a) or (b). For a plan year or 12-month period 
beginning before January 1, 1988, any underlying definition of 
compensation may be used to measure the amount of employees' 
compensation for purposes of this definition, provided that the 
definition was nondiscriminatory based on the facts and circumstances in 
existence for that plan year or for the plan year in which that 12-month 
period ends.
    (2) Determination period for section 414(s) nondiscrimination 
requirement--(i) General rule. If an underlying definition of 
compensation must satisfy the nondiscrimination requirement in Sec. 
1.414(s)-1(d)(3) in order to satisfy section 414(s) for a plan year, any 
one of the following determination periods may be used to satisfy the 
nondiscrimination requirement--
    (A) The plan year;
    (B) The calendar year ending in the plan year; or
    (C) The 12-month period ending in the plan year that is used to 
determine the underlying definition of compensation.
    (ii) Exception for partial plan year compensation. Notwithstanding 
the general rule in paragraph (2)(i) of this definition, if the period 
for measuring the underlying compensation is the portion of the plan 
year during which each employee is a participant in the plan (as 
provided in paragraph (4) of the definition of plan year compensation in 
this section), that period must be used as the determination period.
    (3) Plans using permitted disparity. In the case of a section 401(l) 
plan or a plan that imputes permitted disparity in accordance with Sec. 
1.401(a)(4)-7, an underlying definition of compensation is not section 
414(s) compensation if the definition results in significant under- 
inclusion of compensation for employees.
    (4) Double proration of service and compensation. If a defined 
benefit plan prorates benefit accruals as permitted under section 
411(b)(4)(B) by crediting less than full years of participation, then 
compensation for a plan year, 12-month period, or other specified period 
that is used to determine the amount of an employee's benefits under the 
plan will not fail to be section 414(s) compensation, merely because the 
amount of compensation for that period is adjusted to reflect the 
equivalent of full-time compensation to the extent necessary to satisfy 
the requirements of 29 CFR 2530.204-2(d) (regarding

[[Page 180]]

double proration of service and compensation). This adjustment is 
disregarded in determining whether the underlying definition of 
compensation used satisfies the requirements of section 414(s). Thus, 
for example, if the underlying definition of compensation is an 
alternative definition that must satisfy the nondiscrimination 
requirement of Sec. 1.414(s)-1(d)(3), in determining whether that 
requirement is satisfied with regard to the underlying definition, the 
compensation included for any employee is determined without any 
adjustment to reflect the equivalent of full-time compensation required 
by 29 CFR 2530.204-2(d).
    Social security supplement. Social security supplement is defined in 
Sec. 1.411(a)-7(c)(4)(ii).
    Standard interest rate. Standard interest rate means an interest 
rate that is neither less than 7.5 percent nor greater than 8.5 percent, 
compounded annually. The Commissioner may, in revenue rulings, notices, 
and other guidance of general applicability, change the definition of 
standard interest rate.
    Standard mortality table. Standard mortality table means one of the 
following tables: the UP-1984 Mortality Table (Unisex); the 1983 Group 
Annuity Mortality Table (1983 GAM) (Female); the 1983 Group Annuity 
Mortality Table (1983 GAM) (Male); the 1983 Individual Annuity Mortality 
Table (1983 IAM) (Female); the 1983 Individual Annuity Mortality Table 
(1983 IAM) (Male); the 1971 Group Annuity Mortality Table (1971 GAM) 
(Female); the 1971 Group Annuity Mortality Table (1971 GAM) (Male); the 
1971 Individual Annuity Mortality Table (1971 IAM) (Female); or the 1971 
Individual Annuity Mortality Table (1971 IAM) (Male). These standard 
mortality tables are available from the Society of Actuaries, 475 N. 
Martingale Road, Suite 800, Schaumberg, Illinois 60173. The Commissioner 
may, in revenue rulings, notices, and other guidance of general 
applicability, change the definition of standard mortality table. See 
Sec. 601.601(d)(2)(ii)(b) of this Chapter. The applicable mortality 
table under section 417(e)(3)(A)(ii)(I) is also a standard mortality 
table.
    Straight life annuity. Straight life annuity means an annuity 
payable in equal installments for the life of the employee that 
terminates upon the employee's death.
    Testing age. With respect to an employee, testing age means the age 
determined for the employee under the following rules:
    (1) If the plan provides the same uniform normal retirement age for 
all employees, the employee's testing age is the employee's normal 
retirement age under the plan.
    (2) If a plan provides different uniform normal retirement ages for 
different employees or different groups of employees, the employee's 
testing age is the employee's latest normal retirement age under any 
uniform normal retirement age under the plan, regardless of whether that 
particular uniform normal retirement age actually applies to the 
employee under the plan.
    (3) If the plan does not provide a uniform normal retirement age, 
the employee's testing age is 65.
    (4) If an employee is beyond the testing age otherwise determined 
for the employee under paragraphs (1) through (3) of this definition, 
the employee's testing age is the employee's current age. The rule in 
the preceding sentence does not apply in the case of a defined benefit 
plan that fails to satisfy the requirements of Sec. 1.401(a)(4)-
3(f)(3)(i) (permitting certain increases in benefits that commence after 
normal retirement age to be disregarded).
    Testing service. Testing service is defined in Sec. 1.401(a)(4)-
3(d)(1)(iv).
    Uniform normal retirement age--(1) General rule. Uniform normal 
retirement age means a single normal retirement age under the plan that 
does not exceed the maximum age in paragraph (2) of this definition and 
that is the same for all of the employees in a given group. A group of 
employees does not fail to have a uniform normal retirement age merely 
because the plan contains provisions described in paragraphs (3) and (4) 
of this definition.
    (2) Maximum age. The maximum age is generally 65. However, if all 
employees have the same social security retirement age (within the 
meaning of section 415(b)(8)), the maximum age is

[[Page 181]]

the employees' social security retirement age. Thus, for example, a 
component plan has a uniform normal retirement age of 67 if it defines 
normal retirement age as social security retirement age and all 
employees in the component plan have a social security retirement age of 
67.
    (3) Stated anniversary date--(i) General rule. A group of employees 
does not fail to have a uniform normal retirement age merely because the 
plan provides that the normal retirement age of all employees in the 
group is the later of a stated age (not exceeding the maximum age in 
paragraph (2) of this definition) or a stated anniversary no later than 
the fifth anniversary of the time each employee commenced participation 
in the plan. For employees who commenced participation in the plan 
before the first plan year beginning on or after January 1, 1988, the 
stated anniversary date may be later than the anniversary described in 
the preceding sentence if it is no later than the earlier of the tenth 
anniversary of the date the employee commenced participation in the plan 
(or such earlier anniversary selected by the employer, if less than 10) 
or the fifth anniversary of the first day of the first plan year 
beginning on or after January 1, 1988.
    (ii) Use of service other than anniversary of commencement of 
participation. In lieu of using a stated anniversary date as permitted 
under paragraph (3)(i) of this definition, a plan may use a stated 
number of years of service measured on another basis, provided that the 
determination is made on a basis that satisfies section 411(a)(8) and 
that the stated number of years of service does not exceed the number of 
anniversaries permitted under paragraph (3)(i) of this definition. For 
example, a uniform normal retirement age could be based on the earlier 
of the fifth anniversary of the commencement of participation and the 
completion of five years of vesting service.
    (4) Conversion of normal retirement age to normal retirement date. A 
group of employees does not fail to have a uniform normal retirement age 
merely because a defined benefit plan provides for the commencement of 
normal retirement benefits on different retirement dates for different 
employees if each employee's normal retirement date is determined on a 
reasonable basis with reference to an otherwise uniform normal 
retirement age and the difference between the normal retirement date and 
the uniform normal retirement age cannot exceed six months for any 
employee. Thus, for example, benefits under a plan do not fail to 
commence at a uniform normal retirement age of age 62 for purposes of 
Sec. 1.401(a)(4)-3(b)(2)(i), merely because the plan's normal 
retirement date is defined as the last day of the plan year nearest 
attainment of age 62.
    Year of service. Year of service means a year of service as defined 
in the plan for a specific purpose, including the method of crediting 
service for that purpose under the plan.
