Sec. 1.410(b)-4  Nondiscriminatory classification test.

    (a) In general. A plan satisfies the nondiscriminatory 
classification test of this section for a plan year if and only if, for 
the plan year, the plan benefits the employees who qualify under a 
classification established by the employer in accordance with paragraph 
(b) of this section, and the classification of employees is 
nondiscriminatory under paragraph (c) of this section.
    (b) Reasonable classification established by the employer. A 
classification is established by the employer in accordance with this 
paragraph (b) if and only if, based on all the facts and circumstances, 
the classification is reasonable and is established under objective 
business criteria that identify the category of employees who benefit 
under the plan. Reasonable classifications generally include specified 
job categories, nature of compensation (i.e., salaried or hourly), 
geographic location, and similar bona fide business criteria. An 
enumeration of employees by name or other specific criteria having 
substantially the same effect as an enumeration by name is not 
considered a reasonable classification.
    (c) Nondiscriminatory classification--(1) General rule. A 
classification is nondiscriminatory under this paragraph (c) for a plan 
year if and only if the group of employees included in the

[[Page 560]]

classification benefiting under the plan satisfies the requirements of 
either paragraph (c)(2) or (c)(3) of this section for the plan year.
    (2) Safe harbor. A plan satisfies the requirement of this paragraph 
(c)(2) for a plan year if and only if the plan's ratio percentage is 
greater than or equal to the employer's safe harbor percentage, as 
defined in paragraph (c)(4)(i) of this section. See Sec. 1.410(b)-9 for 
the definition of a plan's ratio percentage.
    (3) Facts and circumstances--(i) General rule. A plan satisfies the 
requirements of this paragraph (c)(3) if and only if--
    (A) The plan's ratio percentage is greater than or equal to the 
unsafe harbor percentage, as defined in paragraph (c)(4)(ii) of this 
section, and
    (B) The classification satisfies the factual determination of 
paragraph (c)(3)(ii) of this section.
    (ii) Factual determination. A classification satisfies this 
paragraph (c)(3)(ii) if and only if, based on all the relevant facts and 
circumstances, the Commissioner finds that the classification is 
nondiscriminatory. No one particular fact is determinative. Included 
among the facts and circumstances relevant in determining whether a 
classification is nondiscriminatory are the following--
    (A) The underlying business reason for the classification. The 
greater the business reason for the classification, the more likely the 
classification is to be nondiscriminatory. Reducing the employer's cost 
of providing retirement benefits is not a relevant business reason.
    (B) The percentage of the employer's employees benefiting under the 
plan. The higher the percentage, the more likely the classification is 
to be nondiscriminatory.
    (C) Whether the number of employees benefiting under the plan in 
each salary range is representative of the number of employees in each 
salary range of the employer's workforce. In general, the more 
representative the percentages of employees benefiting under the plan in 
each salary range, the more likely the classification is to be 
nondiscriminatory.
    (D) The difference between the plan's ratio percentage and the 
employer's safe harbor percentage. The smaller the difference, the more 
likely the classification is to be nondiscriminatory.
    (E) The extent to which the plan's average benefit percentage 
(determined under Sec. 1.410(b)-5) exceeds 70 percent.
    (4) Definitions--(i) Safe harbor percentage. The safe harbor 
percentage of an employer is 50 percent, reduced by \3/4\ of a 
percentage point for each whole percentage point by which the nonhighly 
compensated employee concentration percentage exceeds 60 percent. See 
paragraph (c)(4)(iv) for a table that illustrates the safe harbor 
percentage and unsafe harbor percentage.
    (ii) Unsafe harbor percentage. The unsafe harbor percentage of an 
employer is 40 percent, reduced by \3/4\ of a percentage point for each 
whole percentage point by which the nonhighly compensated employee 
concentration percentage exceeds 60 percent. However, in no case is the 
unsafe harbor percentage less than 20 percent.
    (iii) Nonhighly compensated employee concentration percentage. The 
nonhighly compensated employee concentration percentage of an employer 
is the percentage of all the employees of the employer who are nonhighly 
compensated employees. Employees who are excludable employees for 
purposes of the average benefit test are not taken into account.
    (iv) Table. The following table sets forth the safe harbor and 
unsafe harbor percentages at each nonhighly compensated employee 
concentration percentage:

    (5) Examples. The following examples illustrate the rules in this 
paragraph (c).

    Example 1. Employer A has 200 nonexcludable employees, of whom 120 
are nonhighly compensated employees and 80 are highly compensated 
employees. Employer A maintains a plan that benefits 60 nonhighly 
compensated employees and 72 highly compensated employees. Thus, the 
plan's ratio percentage is 55.56 percent ([60/120]/[72/80]=50%/
90%=0.5556), which is below the percentage necessary to satisfy the 
ratio percentage test of Sec. 1.410(b)-2(b)(2). The employer's 
nonhighly compensated employee concentration percentage is 60 percent 
(120/200); thus, Employer A's safe harbor percentage is 50 percent and 
its unsafe harbor percentage is 40 percent. Because the plan's ratio 
percentage is greater than the safe harbor percentage, the plan's 
classification satisfies the safe harbor of paragraph (c)(2) of this 
section.
    Example 2. The facts are the same as in Example 1, except that the 
plan benefits only 40 nonhighly compensated employees. The plan's ratio 
percentage is thus 37.03 percent ([40/120]/[72/80]=33.33%/90%=0.3703). 
Under these facts, the plan's classification is below the unsafe harbor 
percentage and is thus considered discriminatory.
    Example 3. The facts are the same as in Example 1, except that the 
plan benefits 45 nonhighly compensated employees. The plan's ratio 
percentage is thus 41.67 percent ([45/120]/[72/80]=37.50%/90%=0.4167), 
above the unsafe harbor percentage (40 percent) and below the safe 
harbor percentage (50 percent). The Commissioner may determine that the 
classification is nondiscriminatory after considering all the relevant 
facts and circumstances.
    Example 4. Employer B has 10,000 nonexcludable employees, of whom 
9,600 are nonhighly compensated employees and 400 are highly compensated 
employees. Employer B maintains a plan that benefits 600 nonhighly 
compensated employees and 100 highly compensated employees. Thus, the 
plan's ratio percentage is 25.00 percent ([600/9,600]/[100/400]=6.25%/
25%=0.2500), which is below the percentage necessary to satisfy the 
ratio percentage test of Sec. 1.410(b)-2(b)(2). Employer B's nonhighly 
compensated employee concentration percentage is 96 percent (9,600/
10,000); thus, Employer B's safe harbor percentage is 23 percent, and 
its unsafe harbor percentage is 20 percent. Because the plan's ratio 
percentage (25.00 percent) is greater than the safe harbor percentage 
(23.00 percent), the plan's classification satisfies the safe harbor of 
paragraph (c)(2) of this section.
    Example 5. The facts are the same as in Example 4, except that the 
plan benefits only 400 nonhighly compensated employees. The plan's ratio 
percentage is thus 16.67 percent ([400/9,600]/[100/400]=4.17%/
25%=0.1667). The plan's ratio percentage is below the unsafe harbor 
percentage and thus the classification is considered discriminatory.
    Example 6. The facts are the same as in Example 4, except that the 
plan benefits 500 nonhighly compensated employees. The plan's ratio 
percentage is thus 20.83 percent ([500/9,600]/[100/400]=5.21%/
25%=0.2083), above the unsafe harbor percentage (20 percent) and below 
the safe harbor percentage (23 percent). The Commissioner may determine 
that the classification is nondiscriminatory after considering all the 
facts and circumstances.
