Sec. 1.401(a)(4)-7  Imputation of permitted disparity.

    (a) Introduction. In determining whether a plan satisfies section 
401(a)(4) with respect to the amount of contributions or benefits, 
section 401(a)(5)(C) allows the disparities permitted under section 
401(l) to be taken into account. For purposes of satisfying the safe 
harbors of Secs. 1.401(a)(4)-2(b)(2) and 1.401(a)(4)-3(b), permitted

[[Page 136]]

disparity may be taken into account only by satisfying section 401(l) in 
form in accordance with Sec. 1.401(l)-2 or 1.401(l)-3, respectively. For 
purposes of the general tests of Secs. 1.401(a)(4)-2(c) and 1.401(a)(4)-
3(c), permitted disparity may be taken into account only in accordance 
with the rules of this section. In general, this section allows 
permitted disparity to be arithmetically imputed with respect to 
employer-provided contributions or benefits by determining an adjusted 
allocation or accrual rate that appropriately accounts for the permitted 
disparity with respect to each employee. Paragraph (b) of this section 
provides rules for imputing permitted disparity with respect to 
employer-provided contributions by adjusting each employee's unadjusted 
allocation rate. Paragraph (c) of this section provides rules for 
imputing permitted disparity with respect to employer-provided benefits 
by adjusting each employee's unadjusted accrual rate. Paragraph (d) of 
this section provides rules of general application.
    (b) Adjusting allocation rates--(1) In general. The rules in this 
paragraph (b) produce an adjusted allocation rate for each employee by 
determining the excess contribution percentage under the hypothetical 
formula that would yield the allocation actually received by the 
employee, if the plan took into account the full disparity permitted 
under section 401(l)(2) and used the taxable wage base as the 
integration level. This adjusted allocation rate is used to determine 
whether the amount of contributions under the plan satisfies the general 
test of Sec. 1.401(a)(4)-2(c) and to apply the average benefit 
percentage test on the basis of contributions under Sec. 1.410(b)-5(d). 
Paragraphs (b)(2) and (b)(3) of this section apply to employees whose 
plan year compensation does not exceed and does exceed, respectively, 
the taxable wage base, and paragraph (b)(4) of this section provides 
definitions.
    (2) Employees whose plan year compensation does not exceed taxable 
wage base. If an employee's plan year compensation does not exceed the 
taxable wage base, the employee's adjusted allocation rate is the lesser 
of the A rate and the B rate determined under the formulas below, where 
the permitted disparity rate and the unadjusted allocation rate are 
determined under paragraph (b)(4) (ii) and (iv) of this section, 
respectively.

A Rate = 2xunadjusted allocation rate
B Rate = unadjusted allocation rate + permitted disparity rate

    (3) Employees whose plan year compensation exceeds taxable wage 
base. If an employee's plan year compensation exceeds the taxable wage 
base, the employee's adjusted allocation rate is the lesser of the C 
rate and the D rate determined under the formulas below, where 
allocations and the permitted disparity rate are determined under 
paragraph (b)(4) (i) and (ii) of this section, respectively.

    (4) Definitions. In applying this paragraph (b), the following 
definitions govern--
    (i) Allocations. Allocations means the amount determined by 
multiplying the employee's plan year compensation by the employee's 
unadjusted allocation rate.
    (ii) Permitted disparity rate--(A) General rule. Permitted disparity 
rate means the rate in effect as of the beginning of the plan year under 
section 401(l)(2)(A)(ii) (e.g., 5.7 percent for plan years beginning in 
1990).
    (B) Cumulative permitted disparity limit. Notwithstanding paragraph

[[Page 137]]

(b)(4)(ii)(A) of this section, the permitted disparity rate is zero for 
an employee who has benefited under a defined benefit plan taken into 
account under Sec. 1.401(l)-5(a)(3) for a plan year that begins on or 
after one year from the first day of the first plan year to which these 
regulations apply, as set forth in Sec. 1.401(a)(4)-13 (a) and (b), if 
imputing permitted disparity would result in a cumulative disparity 
fraction for the employee, as defined in Sec. 1.401(l)-5(c)(2), that 
exceeds 35. See Sec. 1.401(l)-5(c)(1) for special rules for determining 
whether an employee has benefited under a defined benefit plan for this 
purpose.
    (iii) Taxable wage base. Taxable wage base means the taxable wage 
base, as defined in Sec. 1.401(l)-1(c)(32), in effect as of the 
beginning of the plan year.
    (iv) Unadjusted allocation rate. Unadjusted allocation rate means 
the employee's allocation rate determined under Sec. 1.401(a)(4)-
2(c)(2)(i) for the plan year (expressed as a percentage of plan year 
compensation), without imputing permitted disparity under this section.
    (5) Example. The following example illustrates the rules in this 
paragraph (b):

    Example. (a) Employees M and N participate in a defined contribution 
plan maintained by Employer X. Employee M has plan year compensation of 
$30,000 in the 1990 plan year and has an unadjusted allocation rate of 
five percent. Employee N has plan year compensation of $100,000 in the 
1990 plan year and has an unadjusted allocation rate of eight percent. 
The taxable wage base in 1990 is $51,300.
    (b) Because Employee M's plan year compensation does not exceed the 
taxable wage base, Employee M's A rate is 10 percent (2x5 percent), and 
Employee M's B rate is 10.7 percent (5 percent+5.7 percent). Thus, 
Employee M's adjusted allocation rate is 10 percent, the lesser of the A 
rate and the B rate.
    (c) Employee N's allocations are $8,000 (8 percentx$100,000). 
Because Employee N's plan year compensation exceeds the taxable wage 
base, Employee N's C rate is 10.76 percent ($8,000 divided by ($100,000-
(\1/2\x$51,300))), and Employee N's D rate is 10.92 percent (($8,000+ 
(5.7 percentx$51,300)) divided by $100,000). Thus, Employee N's adjusted 
allocation rate is 10.76 percent, the lesser of the C rate and the D 
rate.

    (c) Adjusting accrual rates--(1) In general. The rules in this 
paragraph (c) produce an adjusted accrual rate for each employee by 
determining the excess benefit percentage under the hypothetical plan 
formula that would yield the employer-provided accrual actually received 
by the employee, if the plan took into account the full permitted 
disparity under section 401(l)(3)(A) in each of the first 35 years of an 
employee's testing service under the plan and used the employee's 
covered compensation as the integration level. This adjusted accrual 
rate is used to determine whether the amount of employer-provided 
benefits under the plan satisfies the alternative safe harbor for flat 
benefit plans under Sec. 1.401(a)(4)-3(b)(4)(i)(C)(3) or the general 
test of Sec. 1.401(a)(4)-3(c), and to apply the average benefit 
percentage test on the basis of benefits under Sec. 1.410(b)-5. 
Paragraphs (c)(2) and (c)(3) of this section apply to employees whose 
average annual compensation does not exceed and does exceed, 
respectively, covered compensation, and paragraph (c)(4) of this section 
provides definitions. Paragraph (c)(5) of this section provides a 
special rule for employees with negative unadjusted accrual rates.
    (2) Employees whose average annual compensation does not exceed 
covered compensation. If an employee's average annual compensation does 
not exceed the employee's covered compensation, the employee's adjusted 
accrual rate is the lesser of the A rate and the B rate determined under 
the formulas below, where the permitted disparity factor and the 
unadjusted accrual rate are determined under paragraph (c)(4)(iii) and 
(v) of this section, respectively.

    (3) Employees whose average annual compensation exceeds covered 
compensation. If an employee's average annual compensation exceeds the 
employee's covered compensation, the employee's adjusted accrual rate is 
the lesser of the C rate and D rate determined under the formulas below, 
where the employer-provided accrual and the permitted disparity factor 
are determined under paragraph (c)(4)(ii) and (iii) of this section, 
respectively.
[GRAPHIC] [TIFF OMITTED] TC05OC91.014

    (4) Definitions. For purposes of this paragraph (c), the following 
definitions apply.
    (i) Covered compensation. Covered compensation means covered 
compensation as defined in Sec. 1.401(l)-1(c)(7). Notwithstanding 
Sec. 1.401(l)-1(c)(7)(iii), an employee's covered compensation must be 
automatically adjusted each plan year for purposes of applying this 
paragraph (c).
    (ii) Employer-provided accrual. Employer-provided accrual means the 
amount determined by multiplying the employee's average annual 
compensation by the employee's unadjusted accrual rate.
    (iii) Permitted disparity factor--(A) General rule. Permitted 
disparity factor for an employee means the sum of the employee's annual 
permitted disparity factors determined under paragraph (c)(4)(iii)(B) of 
this section for each of the years in the measurement period used for 
determining the employee's accrual rate in Sec. 1.401(a)(4)-3(d)(1), 
divided by the employee's testing service during that measurement 
period.
    (B) Annual permitted disparity factor--(1) Definition. An employee's 
annual permitted disparity factor is generally 0.75 percent adjusted, 
pursuant to Sec. 1.401(l)-3(e), using as the age at which benefits 
commence the lesser of age 65 or the employee's testing age. No 
adjustments are made in the annual permitted disparity factor unless an 
employee's testing age is different from the employee's social security 
retirement age. An annual permitted disparity factor that is less than 
the annual permitted disparity factor described in the first sentence of 
this paragraph (c)(4)(iii)(B)(1) may be used if it is a uniform 
percentage of that factor (e.g., 50 percent of the annual permitted 
disparity factor) or a fixed percentage (e.g., 0.65 percent) for all 
employees.
    (2) Annual permitted disparity factor after 35 years. For purposes 
of determining the sum described in paragraph (c)(4)(iii)(A) of this 
section, the annual permitted disparity factor for each of the 
employee's first 35 years of testing service is the amount described in 
paragraph (c)(4)(iii)(B)(1) of this section, and the annual permitted 
disparity factor in any subsequent year equals zero. This rule applies 
regardless of whether the end of the measurement period extends beyond 
an employee's first 35 years of testing service. Thus, for example, if 
the measurement period is the current plan year and the employee 
completed 35 years of testing service prior to the beginning of the 
current plan year, under this paragraph (c)(4)(iii)(B)(2) the annual 
permitted disparity factor in the current plan year (and hence the sum 
of the annual permitted disparity factors for each year in the 
measurement period) is zero.
    (3) Cumulative permitted disparity limit. The 35 years used in 
paragraph (c)(4)(iii)(B)(2) of this section must be reduced by the 
employee's cumulative disparity fraction, as defined in Sec. 1.401(l)-
5(c)(2), but determined solely with respect to the employee's total 
years of service under all plans taken into account under Sec. 1.401(l)-
5(a)(3) during the measurement period, other than the plan being tested.

[[Page 139]]

    (iv) Social security retirement age. Social security retirement age 
means social security retirement age as defined in section 415(b)(8).
    (v) Unadjusted accrual rate. Unadjusted accrual rate means the 
normal or most valuable accrual rate, whichever is being determined for 
the employee under Sec. 1.401(a)(4)-3(d), expressed as a percentage of 
average annual compensation, without imputing permitted disparity under 
this section.
    (5) Employees with negative unadjusted accrual rates. 
Notwithstanding the formulas in paragraph (c)(2) and (c)(3) of this 
section, if an employee's unadjusted accrual rate is less than zero, the 
employee's adjusted accrual rate is deemed to be the employee's 
unadjusted accrual rate.
    (6) Example. The following example illustrates the rules in this 
paragraph (c):

    Example. (a) Employees M and N participate in a defined benefit plan 
that uses a normal retirement age of 65. The plan is being tested for 
the plan year under Sec. 1.401(a)(4)-3(c), using unadjusted accrual 
rates determined using a plan year measurement period under 
Sec. 1.401(a)(4)-3(d)(1)(iii)(A). Employee M has an unadjusted normal 
accrual rate of 1.48 percent, average annual compensation of $21,000, 
and an employer-provided accrual of $311 (1.48 percentx$21,000). 
Employee N has an unadjusted normal accrual rate of 1.7 percent, average 
annual compensation of $106,000, and an employer-provided accrual of 
$1,802 (1.7 percentx$106,000). The covered compensation of both 
Employees M and N is $25,000, and social security retirement age for 
both employees is 65. Neither employee has testing service of more than 
35 years and neither has ever participated in another plan.
    (b) Because Employee M's average annual compensation does not exceed 
covered compensation, Employee M's A rate is 2.96 percent (2.0x1.48 
percent), and Employee M's B rate is 2.23 percent (1.48 percent+0.75 
percent). Thus, Employee M's adjusted accrual rate is 2.23 percent, the 
lesser of the A rate and the B rate.
    (c) Because Employee N's average annual compensation exceeds covered 
compensation, Employee N's C rate is 1.93 percent ($1,802/($106,000-
(0.5x$25,000))), and Employee N's D rate is 1.88 percent (($1,802+(0.75 
percentx$25,000))/$106,000). Thus, Employee N's adjusted accrual rate is 
1.88 percent, the lesser of the C rate and the D rate.

    (d) Rules of general application--(1) Eligible plans. The rules in 
this section may be used only for those plans to which the permitted 
disparity rules of section 401(l) are available. See Sec. 1.401(l)-
1(a)(3).
    (2) Exceptions from consistency requirements. A plan does not fail 
to satisfy the consistency requirements of Sec. 1.401(a)(4)-2(c)(2)(vi) 
or Sec. 1.401(a)(4)-3(d)(2)(i) merely because the plan does not impute 
disparity for some employees to the extent required to comply with 
paragraph (d)(3) of this section, or because the plan does not impute 
disparity for any employees (including self-employed individuals within 
the meaning of section 401(c)(1)) who are not covered by any of the 
taxes under section 3111(a), section 3221, or section 1401.
    (3) Overall permitted disparity. The annual overall permitted 
disparity limits of Sec. 1.401(l)-5(b) apply to the employer-provided 
contributions and benefits for an employee under all plans taken into 
account under Sec. 1.401(l)-5(a)(3). Thus, if an employee who benefits 
under the plan for the current plan year also benefits under a section 
401(l) plan for the plan year ending with or within the current plan 
year, permitted disparity may not be imputed for that employee for the 
plan year. See Sec. 1.401(l)-5(b)(9), Example 4. Similarly, if an 
employee who benefits under the plan for the current plan year also 
benefits under another plan of the employer for the plan year ending 
with or within the current plan year, disparity may be imputed for that 
employee under only one of the plans.
