Sec. 1.401(a)(4)-6  Contributory defined benefit plans.

    (a) Introduction. This section provides rules necessary for 
determining whether a contributory DB plan satisfies the 
nondiscriminatory amount requirement of Sec. 1.401(a)(4)-1(b)(2). 
Paragraph (b) of this section provides rules for determining the amount 
of benefits derived from employer contributions (employer-provided 
benefits) under a contributory DB plan for purposes of determining 
whether the plan satisfies Sec. 1.401(a)(4)-1(b)(2) with respect to 
such amounts. Paragraph (c) of this section provides the exclusive rules 
for determining whether a contributory DB plan satisfies Sec. 
1.401(a)(4)-1(b)(2) with respect to the amount of benefits derived from 
employee contributions not allocated to separate accounts (employee-
provided benefits). See Sec. 1.401(a)(4)-1(b)(2)(ii)(B) for the 
exclusive tests applicable to employee contributions allocated to 
separate accounts under a section 401(m) plan.
    (b) Determination of employer-provided benefit--(1) General rule. An 
employee's employer-provided benefit under a contributory DB plan for 
purposes of section 401(a)(4) equals the difference between the 
employee's total benefit and the employee's employee-provided benefit 
under the plan. The rules of section 411(c) generally must be used to 
determine the employee's employer-provided benefit for this purpose. 
However, paragraphs (b)(2) through (b)(6) of this section provide 
alternative methods for determining the employee's employer-provided 
benefit.
    (2) Composition-of-workforce method--(i) General rule. A 
contributory DB plan that satisfies paragraph (b)(2)(ii) (A) and (B) of 
this section may determine employees' employer-provided benefit rates 
under the rules of paragraph (b)(2)(iii) of this section.
    (ii) Eligibility requirements--(A) Uniform rate of employee 
contributions. A contributory DB plan satisfies this paragraph 
(b)(2)(ii)(A) if all employees make employee contributions at the same 
rate, expressed as a percentage of plan year compensation (the employee 
contribution rate). A plan does not fail to satisfy this paragraph 
(b)(2)(ii)(A) merely because it eliminates employee contributions for 
all employees with plan year compensation below a specified contribution 
breakpoint that is either a stated dollar amount or a stated percentage 
of covered compensation (within the meaning of Sec. 1.401(l)-1(c)(7)); 
or merely because all employees make employee contributions at the same 
rate (expressed as a percentage of plan year compensation) with respect 
to plan year compensation up to the contribution breakpoint (base 
employee contribution rate) and at a higher rate (expressed as a 
percentage of plan year compensation) that is the same for all employees 
with respect to plan year compensation above the contribution breakpoint 
(excess employee contribution rate). A plan described in paragraph 
(c)(4)(i) of this section that satisfies paragraph (c)(4)(iii) of this 
section is deemed to satisfy this paragraph.
    (B) Demographic requirements--(1) In general. A contributory DB plan 
satisfies this paragraph (b)(2)(ii)(B) if it satisfies either of the 
demographic tests in paragraph (b)(2)(ii)(B) (2) or (3) of this section.
    (2) Minimum percentage test. This test is satisfied only if more 
than 40 percent of the NHCEs in the plan have attained ages at least 
equal to the plan's target

[[Page 133]]

age, and more than 20 percent of the NHCEs in the plan have attained 
ages at least equal to the average attained age of the HCEs in the plan. 
For this purpose, a plan's target age is the lower of age 50 or the 
average attained age of the HCEs in the plan minus X years, where X 
equals 20 minus the product of five times the employee contribution rate 
under the plan. In no case, however, may X years be fewer than zero (0) 
years. Thus, for example, if the average attained age of the HCEs in the 
plan is 53 and the employee contribution rate is two percent of plan 
year compensation, the plan's target age is 43 years (i.e., 53-(20-
(5x2))).
    (3) Ratio test. This test is satisfied only if the percentage of all 
nonhighly compensated nonexcludable employees, who are in the plan and 
who have attained ages at least equal to the average attained age of the 
HCEs in the plan, is at least 70 percent of the percentage of all highly 
compensated nonexcludable employees, who are in the plan and who have 
attained ages at least equal to the average attained age of the HCEs in 
the plan. Attained ages must be determined as of the beginning of the 
plan year. In lieu of determining the actual distribution of the 
attained ages of the HCEs, an employer may assume that 50 percent of all 
HCEs have attained ages at least equal to the average attained age of 
the HCEs.
    (iii) Determination of employer-provided benefit--(A) Safe harbor 
plans other than section 401(l) plans. For purposes of applying the 
exception to the safe harbor in Sec. 1.401(a)(4)-3(b)(6)(viii) with 
respect to employer-provided benefits under a plan other than a section 
401(l) plan, the employee's entire accrued benefit is treated as 
employer-provided.
    (B) Section 401(l) plans--(1) General rule. For purposes of applying 
the exception to the safe harbor in Sec. 1.401(a)(4)-3(b)(6)(viii) with 
respect to employer-provided benefits under a section 401(l) plan, an 
employee's base benefit percentage and excess benefit percentage are 
reduced, or an employee's gross benefit percentage is reduced, by 
subtracting the product of the employee contribution rate and the factor 
determined under paragraph (b)(2)(iv) of this section from the 
respective percentages for the plan year. For this purpose, the employee 
contribution rate is the highest rate of employee contributions 
applicable to any potential level of plan year compensation for that 
plan year under the plan.
    (2) Excess plans with varying contribution rates. In the case of a 
defined benefit excess plan described in the second sentence of 
paragraph (b)(2)(ii)(A) of this section, solely for purposes of reducing 
an employee's base benefit percentage as required under paragraph 
(b)(2)(iii)(B)(1) of this section, it may be assumed that the employee's 
employee contribution rate equals the weighted average of the base 
employee contribution rate and the excess employee contribution rate. In 
determining this weighted average, the weight of the base employee 
contribution rate is equal to a fraction, the numerator of which is the 
lesser of the integration level and the contribution breakpoint and the 
denominator of which is the integration level. The weight of the excess 
employee contribution rate is equal to the difference between one and 
the weight of the base employee contribution rate.
    (3) Offset plans with varying contribution rates. In the case of an 
offset plan described in the second sentence of paragraph (b)(2)(ii)(A) 
of this section, an equivalent adjustment to the alternative method in 
paragraph (b)(2)(iii)(B)(2) of this section may be made to the offset 
percentage.
    (C) Employer-provided benefits under the general test. For purposes 
of applying the general test of Sec. 1.401(a)(4)-3(c) with respect to 
employer-provided benefits, an employee's normal and most valuable 
accrual rates otherwise determined under Sec. 1.401(a)(4)-3(d) (without 
applying any of the options under Sec. 1.401(a)(4)-3(d)(3) other than 
the fresh-start alternative of Sec. 1.401(a)(4)-3(d)(3)(iii)) are each 
reduced by subtracting the product of the employee's contributions 
(expressed as a percentage of plan year compensation) and the factor 
determined under paragraph (b)(2)(iv) of this section from the 
respective accrual rates. A plan may then apply the optional rules in 
Sec. 1.401(a)(4)-3(d)(3) (i) and (ii) to this resulting accrual rate.

[[Page 134]]

    (D) Additional limitation. A plan may not use the composition-of-
workforce method provided in this paragraph (b)(2) to determine an 
employee's base benefit percentage, excess benefit percentage, gross 
benefit percentage, offset percentage, or accrual rates unless employee 
contributions have been made at the same rate (or rates) throughout the 
period after the fresh-start date or throughout the measurement period 
used to determine accrual rates.
    (iv) Determination of plan factor. The factor for a plan is 
determined under the following table based on the average entry age of 
the employees in the plan and on whether the plan determines benefits 
based on average compensation. For this purpose, average entry age 
equals the average attained age of all employees in the plan, minus the 
average years of participation of all employees in the plan. A plan is 
treated as determining benefits based on average compensation if it 
determines benefits based on compensation averaged over a specified 
period not exceeding five consecutive years (or the employee's entire 
period of employment with the employer, if shorter).

------------------------------------------------------------------------

    (v) Examples. The following examples illustrate the rules of this 
paragraph (b)(2):

    Example 1. Plan A is a contributory DB plan that is a defined 
benefit excess plan providing a benefit equal to 2.0 percent of 
employees' average annual compensation at or below covered compensation, 
plus 2.5 percent of average annual compensation above covered 
compensation, times years of service up to 35. Under the plan, average 
annual compensation is determined using a five-consecutive-year period 
for purposes of Sec. 1.401(a)(4)-3(e)(2). The plan requires employee 
contributions at a rate of four percent of plan year compensation for 
all employees. Assume that the plan satisfies the demographic 
requirements of paragraph (b)(2)(ii)(B) of this section. Under these 
facts, the plan satisfies the eligibility requirements of paragraph 
(b)(2)(ii) of this section. Assume, further, that the average attained 
age for all employees in the plan is 55, and that the average years of 
participation of all employees in the plan is 10. The average entry age 
for the plan is therefore 45, and, accordingly, the appropriate factor 
under the table is 0.2. Thus, in applying the safe harbor requirements 
of Sec. 1.401(a)(4)-3(b) to this plan for the plan year (including the 
requirements of Sec. 1.401(l)-3), the employee's base benefit 
percentage and excess benefit percentage are each reduced by 0.8 percent 
(4 percentx0.2) and equal 1.2 percent and 1.7 percent, respectively.
    Example 2. The facts are the same as in Example 1, except that the 
employee contribution rate is two percent of plan year compensation up 
to the covered compensation level, and four percent for plan year 
compensation at or above that contribution breakpoint. The employer 
elects to apply the alternative method in paragraph (b)(2)(iii)(B)(2) of 
this section to determine the reduction in the base benefit percentage. 
Because the contribution breakpoint is equal to the integration level, 
the weight of the employee contribution rate below the contribution 
breakpoint is 100 percent, and the weight of the employee contribution 
rate above the contribution breakpoint is zero. Thus, the weighted 
average of employee contribution rates is two percent. Under the 
alternative method in paragraph (b)(2)(iii)(B)(2) of this section, the 
reduction in the employee's base benefit percentage is 0.4. In applying 
the safe harbor requirements of Sec. 1.401(a)(4)-3(b) to this plan 
(including the requirements of Sec. 1.401(l)-3), the employee's base 
benefit percentage is 1.6 percent, and the employee's excess benefit 
percentage is 1.7.
    Example 3. The facts are the same as in Example 1, except that the 
employee contribution rate is two percent of plan year compensation up 
to 50 percent of the covered compensation level, and four percent for 
plan year compensation at or above that contribution breakpoint. Because 
the contribution breakpoint is equal to 50 percent of the integration 
level, the weight of the employee contribution rate below the 
contribution breakpoint is 50 percent, and the weight of the employee 
contribution rate above the contribution breakpoint is 50 percent. Thus, 
the weighted average of employee contribution rates is three percent. 
Under the alternative method in paragraph (b)(2)(iii)(B)(2) of this 
section, the reduction in the employee's base benefit percentage is 0.6. 
In applying the safe harbor requirements of Sec. 1.401(a)(4)-3(b) to 
this plan (including the requirements of Sec. 1.401(l)-3), the 
employee's base benefit percentage is 1.4 percent, and the employee's 
excess benefit percentage is 1.7.

[[Page 135]]

    Example 4. The facts are the same as in Example 1, except that the 
plan is tested using the general test in Sec. 1.401(a)(4)-3(c). Assume 
Employee M benefits under Plan A and has a normal accrual rate for the 
plan year (calculated with respect to Employee M's total accrued 
benefit) of 2.2 percent of average annual compensation. In applying the 
general test in Sec. 1.401(a)(4)-3(c) with respect to employer-provided 
benefits, this rate is reduced by 0.8 to yield a normal accrual rate of 
1.4 percent. This rate may then be adjusted using either of the optional 
rules in Sec. 1.401(a)(4)-3(d)(3)(i) or (ii).

    (3) Minimum-benefit method--(i) Application of uniform factors. A 
contributory DB plan that satisfies the uniform rate requirement of 
paragraph (b)(2)(ii)(A) of this section and the minimum benefit 
requirement of paragraph (b)(3)(ii) of this section may apply the 
adjustments provided in paragraph (b)(2)(iii) of this section as if the 
average entry age of employees in the plan were within the range of 30 
to 40, without regard to the actual demographics of the employees in the 
plan.
    (ii) Minimum benefit requirement. This requirement is satisfied if 
the plan provides that, in plan years beginning on or after the 
effective date of these regulations, as set forth in Sec. 1.401(a)(4)-
13(a) and (b), each employee will accrue a benefit that equals or 
exceeds the sum of--
    (A) The accrued benefit derived from employee contributions made for 
plan years beginning on or after the effective date of these 
regulations, determined in accordance with section 411(c); and
    (B) Fifty percent of the total benefit accrued in plan years 
beginning on or after the effective date of these regulations, as 
determined under the plan benefit formula without regard to that portion 
of the formula designed to satisfy the minimum benefit requirement of 
this paragraph (b)(3)(ii).
    (iii) Example. The following example illustrates the minimum-benefit 
method of this paragraph (b)(3):

    Example. Plan A is contributory DB plan. For the plan year beginning 
in 1994, Employee M participates in Plan A and accrues a benefit under 
the terms of the plan (without regard to the minimum benefit requirement 
of paragraph (b)(3)(ii) of this section) of $3,000. The portion of 
Employee M's benefit accrual for the plan year beginning in 1994 derived 
from employee contributions is $2,000, determined by applying the rules 
of section 411(c) to such contributions. The requirement of paragraph 
(b)(3)(ii) of this section is not satisfied for the plan year beginning 
in 1994 unless the plan provides that Employee M's benefit accrual for 
the plan year beginning in 1994 is equal to $3,500 ($2,000+(50 
percentx$3,000)).

    (4) Grandfather rule for plans in existence on May 14, 1990. A 
contributory DB plan that satisfies paragraph (c)(4) of this section may 
determine an employee's employer-provided benefit by subtracting from 
the employee's total benefit the employee-provided benefits determined 
using any reasonable method set forth in the plan, provided that it is 
the same method used in determining whether the plan satisfies paragraph 
(c)(4)(ii)(D) of this section.
    (5) Government-plan method. A contributory DB plan that is 
established and maintained for its employees by the government of any 
state or political subdivision or by any agency or instrumentality 
thereof may treat an employee's total benefit as entirely employer-
provided.
    (6) Cessation of employee contributions. If a contributory DB plan 
provides that no employee contributions may be made to the plan after 
the last day of the first plan year beginning on or after the effective 
date of these regulations, as set forth in Sec. 1.401(a)(4)-13 (a) and 
(b), the plan may treat an employee's total benefit as entirely 
employer-provided.
    (c) Rules applicable in determining whether employee-provided 
benefits are nondiscriminatory in amount--(1) In general. A contributory 
DB plan satisfies Sec. 1.401(a)(4)-1(b)(2) with respect to the amount 
of employee-provided benefits for a plan year only if the plan satisfies 
the requirements of paragraph (c)(2), (c)(3), or (c)(4) of this section 
for the plan year. This requirement applies regardless of the method 
used to determine the amount of employer-provided benefits under 
paragraph (b) of this section.
    (2) Same rate of contributions. This requirement is satisfied for a 
plan year if the employee contribution rate (within the meaning of 
paragraph (b)(2)(ii)(A) of this section) is the same for all employees 
for the plan year.
    (3) Total-benefits method. This requirement is satisfied for a plan 
year if--

[[Page 136]]

    (i) The total benefits (i.e., the sum of employer-provided and 
employee-provided benefits) under the plan would satisfy Sec. 
1.401(a)(4)-3 if all benefits were treated as employer-provided 
benefits; and
    (ii) The plan's contribution requirements satisfy paragraph 
(b)(2)(ii)(A) of this section.
    (4) Grandfather rules for plans in existence on May 14, 1990--(i) In 
general. This requirement is satisfied for a plan year if the plan 
contained provisions as of May 14, 1990, that meet the requirements of 
paragraph (c)(4)(ii) or (c)(4)(iii) of this section.
    (ii) Graded contribution rates. The plan's provisions meet the 
requirements of this paragraph (c)(4)(ii) if all the following 
requirements are met:
    (A) The provisions require employee contributions at a greater rate 
(expressed as a percentage of compensation) at higher levels of 
compensation than at lower levels of compensation.
    (B) The required rate of employee contributions is not increased 
after May 14, 1990, although the level of compensation at which employee 
contributions are required may be increased or decreased.
    (C) All employees are permitted to make employee contributions under 
the plan at a uniform rate with respect to all compensation, beginning 
no later than the last day of the first plan year to which these 
regulations apply, as set forth in Sec. 1.401(a)(4)-13 (a) and (b).
    (D) The benefits provided on account of employee contributions at 
lower levels of compensation are comparable to those provided on account 
of employee contributions at higher levels of compensation.
    (iii) Prior year compensation. The plan's provisions meet the 
requirements of this paragraph (c)(4)(iii) if they are part of a plan 
maintained by more than one employer that requires employee 
contributions and the rate of required employee contributions, expressed 
as a percentage of compensation for the last calendar year ending before 
the beginning of the plan year, is the same for all employees.
