Sec. 1.414(r)-8  Separate application of section 410(b).

    (a) General rule. If an employer is treated as operating qualified 
separate lines of business for purposes of section 410(b) in accordance 
with Sec. 1.414(r)-1(b) for a testing year, the requirements of section 
410(b) must be applied in accordance with this section separately with 
respect to the employees of each qualified separate line of business for 
purposes of testing all plans of the employer for plan years that begin 
in the testing year (other than a plan tested under the special rule for 
employer-wide plans in Sec. 1.414(r)-(c)(2)(ii) for such a plan year). 
Conversely, if an employer is not treated as operating qualified 
separate lines of business for purposes of section 410(b) in accordance 
with Sec. 1.414(r)-1(b) for a testing year, the requirements of section 
410(b) must be applied on an employer-wide basis for purposes of testing 
all plans of the employer for plan years that begin in the testing year. 
See Sec. 1.414(r)-1(c)(2) and (d)(6). Paragraph (b) of this section 
explains how the requirements of section 410(b) are applied separately 
with respect to the employees of a qualified separate line of business 
for purposes of testing a plan. Paragraph (c) of this section explains 
the coordination between sections 410(b) and 401(a)(4). Paragraph (d) of 
this section provides certain supplementary rules necessary for the 
application of this section.
    (b) Rules of separate application--(1) In general. If the 
requirements of section 410(b) are applied separately with respect to 
the employees of each qualified separate line of business operated by 
the employer for a testing year, a plan (other than a plan that is 
tested under the special rule for employer-wide plans in Sec. 1.414(r)-
1(c)(2)(ii) for a plan year) satisfies the requirements of section 
410(b) only if--
    (i) The plan satisfies section 410(b)(5)(B) of an employer-wide 
basis; and
    (ii) The plan satisfies section 410(b) on a qualified-separate-line-
of-business basis.
    (2) Satisfaction of section 410(b)(5)(B) on an employer-wide basis--
(i) General rule. Section 410(b)(5)(B) provides that a plan is not 
permitted to be tested separately with respect to the employees of a 
qualified separate line of business unless the plan benefits a 
classification of employees found by the Secretary to be 
nondiscriminatory. A plan satisfies this requirement only if the plan 
satisfies either the ratio percentage test of Sec. 1.410(b)-2(b)(2) or 
the nondiscriminatory classification test of Sec. 1.410(b)-4 (without 
regard to the average benefit percentage test of Sec. 1.410(b)-5), 
taking into account the other applicable provisions of Sec. Sec. 
1.410(b)-1 through 1.410(b)-10. For this purpose, the nonexcludable 
employees of the employer taken into account in testing the plan under 
section 410(b) are determined under Sec. 1.410(b)-6, without regard to 
the exclusion in Sec. 1.410(b)-6(e) for employees of other qualified 
separate lines of business of the employer. Thus, in testing a plan 
separately with respect to the employees of one qualified separate line 
of business under this paragraph (b)(2), the otherwise nonexcludable 
employees of the employer's other qualified separate lines of business 
are not treated as excludable employees. However, under the definition 
of ``plan'' in paragraph (d)(2) of this section, these employees are not 
treated as benefiting under the plan for purposes of applying this 
paragraph (b)(2).
    (ii) Application of facts and circumstances requirements under 
nondiscriminatory classification test. The fact that an employer has 
satisfied the qualified-separate-line-of-business requirements in 
Sec. Sec. 1.414(r)-1 through 1.414(r)-7 is taken into account in 
determining whether a classification of employees benefiting under a 
plan that falls between the safe and unsafe harbors satisfies Sec. 
1.410(b)-4(c)(3) (facts and circumstances requirements). Except

[[Page 756]]

in unusual circumstances, this fact will be determinative.
    (iii) Modification of unsafe harbor percentage for plans satisfying 
ratio percentage test at 90 percent level--(A) General rule. If a plan 
benefits a group of employees for a plan year that would satisfy the 
ratio percentage test of Sec. 1.410(b)-2(b)(2) on a qualified-separate-
line-of-business basis under paragraph (b)(3) of this section if the 
percentage in Sec. 1.410(b)-2(b)(2) were increased to 90 percent, the 
unsafe harbor percentage in Sec. 1.410(b)-4(c)(4)(ii) for the plan is 
reduced by five percentage points (not five percent) for the plan year 
and is applied without regard to the requirement that the unsafe harbor 
percentage not be less than 20 percent. Thus, if the requirements of 
this paragraph (b)(2)(iii)(A) are satisfied, the unsafe harbor 
percentage in Sec. 1.410(b)-4(c)(4)(ii) is treated as 35 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.
    (B) Facts and circumstances alternative. If a plan satisfies the 
requirements of paragraph (b)(2)(iii)(A) of this section, but has a 
ratio percentage on an employer-wide basis that falls below the unsafe 
harbor percentage determined under paragraph (b)(2)(iii)(A) of this 
section, the plan nonetheless is deemed to satisfy section 410(b)(5)(B) 
on an employer-wide basis if the Commissioner determines that, on the 
basis of all of the relevant facts and circumstances, the plan benefits 
such employees as qualify under a classification of employees that does 
not discriminate in favor of highly compensated employees.
    (3) Satisfaction of section 410(b) on a qualified-separate-line-of-
business basis. A plan satisfies section 410(b) on a qualified-separate-
line-of-business basis only if the plan satisfies either the ratio 
percentage test of Sec. 1.410(b)-2(b)(2) or the average benefit test of 
Sec. 1.410(b)-2(b)(3) (including the nondiscriminatory classification 
test of Sec. 1.410(b)-4 and the average benefit percentage test of 
Sec. 1.410(b)-5), taking into account the other applicable provisions 
of Sec. Sec. 1.410(b)-1 through 1.410(b)-10. For this purpose, the non-
excludable employees of the employer taken into account in testing the 
plan under section 40(b) are determined under Sec. 1.410(b)-6, taking 
into account the exclusion in Sec. 1.410(b)-6(e) for employees of other 
qualified separate lines of business of the employer. Thus, in testing a 
plan separately with respect to the employees of one qualified separate 
line of business under this paragraph (b)(3), all employees of the 
employer's other qualified separate lines of business are treated as 
excludable employees.
    (4) Examples. The following examples illustrate the application of 
this paragraph (b).

    Example 1. (i) Employer A is treated as operating qualified separate 
lines of business for purposes of section 410(b) in accordance with 
Sec. 1.414(r)-1(b) for the 1994 testing year with respect to all of its 
plans. Employer A operates two qualified separate lines of business as 
determined under Sec. 1.414(r)-1(b)(2), Line 1 and Line 2. Employer A 
maintains only two plans, Plan X which benefits solely employees of Line 
1, and Plan Y which benefits solely employees of Line 2. In testing Plan 
X under section 410(b) with respect to the first testing day for the 
plan year of Plan X beginning in the 1994 testing year, it is determined 
that Employer A has 2,100 nonexcludable employees, of whom 100 are 
highly compensated employees and 2,000 are nonhighly compensated 
employees. After applying Sec. 1.414(r)-7 to these employees, 50 of the 
highly compensated employees and 100 of the nonhighly compensated 
employees are treated as employees of Line 2, and the remaining 50 
highly compensated employees and the remaining 1,900 nonhighly 
compensated employees are treated as employees of Line 1.
    (ii) All of the highly compensated employees and 1,300 of the 
nonhighly compensated employees who are treated as employees of Line 1 
benefit under Plan X. Thus, on an employer-wide basis, Plan X benefits 
50 percent of all Employer A's highly compensated employees (50 out of 
100) and 65 percent of all Employer A's nonhighly compensated employees 
(1,300 out of 2,000). Plan X consequently has a ratio percentage 
determined on an employer-wide basis of 130 percent (65%/50%), see Sec. 
1.410(b)-9, and could satisfy section 410(b) under the ratio percentage 
test of Sec. 1.410(b)-2(b)(2) if that section were applied on an 
employer-wide basis without regard to the provisions of this paragraph 
(b). Under paragraph (a) of this section, however, the requirements of 
section 410(b) must be applied separately with respect to the employees 
of each qualified separate line of business operated by Employer A for 
all plans of Employer A for plan years that begin in the 1994 testing 
year. This rule does

[[Page 757]]

not apply to plans tested under the special rule for employer-wide plans 
in Sec. 1.414(r)-1(c)(2)(ii). Plan X benefits only 65 percent of the 
nonhighly compensated employees of Employer A, however, and therefore 
cannot satisfy the 70 percent requirement necessary to be tested under 
that rule. As a result, for the plan year of Plan X beginning in the 
1994 testing year, Plan X is not permitted to satisfy section 410(b) on 
an employer-wide basis and, instead, is only permitted to satisfy 
section 410(b) separately with respect to the employees of each 
qualified separate line of business operated by Employer A, in 
accordance with paragraphs (b)(2) and (b)(3) of this section.
    Example 2. The facts are the same as in Example 1. All of the 50 
highly compensated employees treated as employees of Line 2 benefit 
under Plan Y, and 80 of the 100 nonhighly compensated employees treated 
as employees of Line 2 benefit under Plan Y. Thus, Plan Y benefits 50 
percent of all Employer A's highly compensated employees (50 out of 100) 
and only 4 percent of all Employer A's nonhighly compensated employees 
(80 out of 2,000). Thus, while Plan Y has a ratio percentage of 80 
percent (80%/100%) on a qualified-separate-line-of-business basis, it 
has a ratio percentage of only 8 percent (4%/50%) on an employer-wide 
basis. See Sec. 1.410(b)-9. Under Sec. 1.410(b)-4(c)(4)(iii), the 
nonhighly compensated employee concentration percentage is 2,000/2,100 
or 95 percent. Because 8 percent is less than 20 percent (the unsafe 
harbor percentage applicable to Employer A under Sec. 1.410(b)-
4(c)(4)(ii)), Plan Y does not satisfy the nondiscriminatory 
classification test of Sec. 1.410(b)-4 on an employer-wide basis. Nor 
does Plan Y satisfy the ratio percentage test of Sec. 1.410(b)-2(b)(2) 
on an employer-wide basis, since 8 percent is less than 70 percent. 
Under these facts, Plan Y does not satisfy section 410(b)(5)(B) on an 
employer-wide basis in accordance with paragraph (b)(2) of this section 
for the plan year of Plan Y beginning in the 1994 testing year, and 
therefore fails to satisfy section 410(b) for that year. This is true 
even though Plan Y satisfies section 410(b) on a qualified-separate-
line-of-business basis in accordance with paragraph (b)(3) of this 
section.
    Example 3. The facts are the same as in Example 2, except that all 
of the employees treated as employees of Line 2 benefit under Plan Y. 
Thus, Plan Y benefits 50 percent of all of Employer A's highly 
compensated employees (50 out of 100) and 5 percent of all of Employer 
A's nonhighly compensated employees (100 out of 2,000). Plan Y therefore 
has a ratio percentage of 100 percent (100%/100%) on a qualified-
separate-line-of-business basis and a ratio percentage of 10 percent 
(5%/50%) on an employer-wide basis. Because Plan Y has a ratio 
percentage of at least 90 percent on a qualified-separate-line-of-
business basis, a reduced unsafe harbor percentage applies to Plan Y 
under paragraph (b)(2)(iii)(A) of this section. The reduced unsafe 
harbor percentage applicable to Plan Y is 8.75 percent because Employer 
A's nonhighly compensated employee concentration percentage is 95 
percent. Plan Y's employer-wide ratio percentage of 10 percent therefore 
exceeds the unsafe harbor percentage. Plan Y thus satisfies section 
410(b)(5)(B) on an employer-wide basis in accordance with paragraph 
(b)(2) of this section for the plan year of Plan Y beginning in the 1994 
testing year. Plan Y also satisfies section 410(b) on a qualified-
separate-line-of-business basis in accordance with paragraph (b)(3) of 
this section.
    Example 4. The facts are the same as in Example 3, except that 
Employer A's total nonexcludable nonhighly compensated employees are 
2,500 (rather than 2,000), of whom 100 are treated as employees of Line 
2 and of whom 90 benefit under Plan Y. Plan Y has a ratio percentage of 
90 percent (90%/100%) on a qualified-separate-line-of-business basis, 
and Employer A's nonhighly compensated employee concentration percentage 
is 2,500/2,600 or 96 percent. Thus, the reduced unsafe harbor percentage 
applicable to Plan Y under paragraph (b)(2)(iii)(A) of this section is 8 
percent. Plan Y benefits 50 percent of all of Employer A's highly 
compensated employees (50 out of 100) and 3.6 percent of all of Employer 
A's nonhighly compensated employees (90 out of 2,500). Plan Y therefore 
has a ratio percentage of only 7.2 percent (3.6%/50%) on an employer-
wide basis, which falls below the reduced unsafe harbor percentage of 8 
percent. Nonetheless, under paragraph (b)(2)(iii)(B) of this section, 
Plan Y will be deemed to satisfy section 410(b)(5)(B) on an employer-
wide basis if the Commissioner determines that, on the basis of all of 
the relevant facts and circumstances, the plan benefits such employees 
as qualify under a classification of employees that does not 
discriminate in favor of highly compensated employees.
    Example 5. (i) The facts are the same as in Example 1, except that 
Plan X benefits only 950 of the employees of Line 1. Assume Plan X 
satisfies the reasonable classification requirement of Sec. 1.410(b)-
4(b) on an employer-wide basis. Plan X benefits 50 percent of all 
Employer A's highly compensated employees (50 out 100) and 47.5 percent 
of all Employer A's nonhighly compensated employees (950 out of 2,000). 
Plan X consequently has a ratio percentage determined on an employer-
wide basis of 95 percent (47.5%/50%), see Sec. 1.410(b)-9, and thus 
satisfies section 410(b)(5)(B) on an employer-wide basis.
    (ii) Plan X has a ratio percentage determined on a qualified-
separate-line-of-business basis of 50 percent (50% / 100%). Because 50 
percent is less than 70 percent, Plan X must satisfy the 
nondiscriminatory classification test of Sec. 1.410(b)-4 and the 
average

[[Page 758]]

benefit percentage test of Sec. 1.410(b)-5 on a qualified-separate-
line-of-business basis in order to satisfy the other requirements of 
section 410(b). Plan X satisfies the nondiscriminatory classification 
requirement of Sec. 1.410(b)-4(c) on a qualified-separate-line-of-
business because its ratio percentage determined on a qualified-
separate-line-of-business basis is more than 22.25 percent, the safe 
harbor percentage applicable to Line 1 under Sec. 1.410(b)-4(c)(4)(i). 
Because Plan X satisfies the reasonable classification requirement of 
Sec. 1.410(b)-4(b) on an employer-wide basis, it is also deemed to 
satisfy this requirement on a qualified-separate-line-of-business basis. 
See Sec. 1.410(b)-7(c)(5). In determining whether Plan X satisfies the 
average benefit percentage test of Sec. 1.410(b)-5, only Plan X and 
only employees of Line 1 are taken into account. See Sec. Sec. 
1.410(b)-6(e) and 1.410(b)-7(e).
    Example 6. The facts are the same as in Example 2, except that, 
prior to the 1994 testing year, Employer A merges Plan X and Plan Y so 
that they form a single plan within the meaning of section 414(l). Under 
the definition of ``plan'' in paragraph (d)(2) of this section, however, 
the portion of the newly merged plan that benefits employees of Line 2 
(former Plan Y) is still treated as a separate plan from the portion of 
the newly merged plan that benefits employees of Line 1 (former Plan X). 
The portion of the newly merged plan that benefits employees of Line 2 
(former Plan Y) fails to satisfy section 410(b) for the reasons stated 
in Example 2. Under these facts, because the portion of the newly merged 
plan that benefits employees of Line 2 fails to satisfy section 410(b), 
the entire newly merged plan fails to satisfy section 410(b) for the 
plan year of the newly merged plan that begins in the 1994 testing year. 
See paragraph (d)(5) of this section.

    (c) Coordination of section 401(a)(4) with section 410(b)--(1) 
General rule. For purposes of these regulations, the requirements of 
section 410(b) encompass the requirements of section 401(a)(4) 
(including, but not limited to, the permitted disparity rules of section 
401(l), the actual deferral percentage test of section 401(k)(3), and 
the actual contribution percentage test of section 401(m)(2)). 
Therefore, if the requirements of section 410(b) are applied separately 
with respect to the employees of each qualified separate line of 
business of an employer for purposes of testing one or more plans of the 
employer for plan years that begin in a testing year, the requirements 
of section 401(a)(4) must also be applied separately with respect to the 
employees of the same qualified separate lines of business for purposes 
of testing the same plans for the same plan years. Furthermore, if 
section 401(a)(4) requires that a group of employees under the plan 
satisfy section 410(b) for purposes of satisfying section 401(a)(4), 
section 410(b) must be applied for this purpose in the same manner 
provided in paragraph (b) of this section. See, for example, Sec. Sec. 
1.401(a)(4)-2(c)(1) and 1.401(a)(4)-3(c)(1) (requiring each rate group 
of employees under a plan to satisfy section 410(b)), Sec. 1.401(a)(4)-
4(b) (requiring the group of employees to whom each benefit, right, or 
feature is currently available under a plan to satisfy section 410(b)), 
and Sec. 1.401(a)(4)-9(c)(1) (requiring the group of employees included 
in each component plan into which a plan is restructured to satisfy 
section 410(b)). Thus, the group of employees must satisfy section 
410(b)(5)(B) on an employer-wide basis in accordance with paragraph 
(b)(2) of this section and also must satisfy section 410(b) on a 
qualified-separate-line-of-business basis in accordance with paragraph 
(b)(3) of this section, in both cases as if the group of employees were 
the only employees benefiting under the plan.
    (2) Examples. The following examples illustrate the application of 
the rule in this paragraph (c).

    Example 1. Employer B is treated as operating qualified separate 
lines of business for purposes of section 410(b) in accordance with 
Sec. 1.414(r)-1(b) for the 1993 testing year. Employer B operates two 
qualified separate lines of business as determined under Sec. 1.414(r)-
1(b)(2), Line 1 and Line 2. Employer B maintains Plan Z, which benefits 
employees in both Line 1 and Line 2. Under the definition of ``plan'' in 
paragraph (d)(2) of this section, the portion of Plan Z that benefits 
employees of Line 1 is treated as a separate plan from the portion of 
Plan Z that benefits employees of Line 2. Under this paragraph (c), this 
result applies for purposes of both section 410(b) and section 
401(a)(4).
    Example 2. The facts are the same as in Example 1, except that Plan 
Z benefits solely employees of Line 1. In testing Plan Z under section 
401(a)(4) for the plan year of Plan Z beginning in the 1993 testing 
year, Employer B restructures Plan Z into several component plans 
(within the meaning of Sec. 1.401(a)(4)-9(c)). Under Sec. 1.401(a)(4)-
9(c)(1), each of these component plans is required to satisfy section 
410(b). This paragraph (c) requires that each of the component plans be

[[Page 759]]

tested separately with respect to the employees of each qualified 
separate line of business operated by Employer B. This testing must be 
done in accordance with paragraph (b) of this section. Consequently, 
each component plan must satisfy section 410(b)(5)(B) on an employer-
wide basis in accordance with paragraph (b)(2) of this section and must 
also satisfy section 410(b) on a qualified-separate-line-of-business 
basis in accordance with paragraph (b)(3) of this section.
    Example 3. The facts are the same as in Example 1, except that Plan 
Z is a profit-sharing plan, and contributions to Plan Z are made 
pursuant to cash or deferred arrangement in which all employees of 
Employer B are eligible to participate. Assume that, as a result, Plan Z 
satisfies the requirements to be tested under the special rule for 
employer-wide plans in Sec. 1.414(r)-1(c)(2)(ii). Under these facts, 
the requirements of sections 410(b), 401(a)(4) and 401(k), including the 
actual deferral percentage test of section 401(k)(3) and Sec. 1.401(k)-
1(b), would generally be required to be applied separately to the 
portions of Plan Z that benefit the employees of Line 1 and Line 2, 
respectively. However, if Plan Z is tested under the special rule in 
Sec. 1.414(r)-1(c)(2)(ii), these requirements must be applied on an 
employer-wide basis.

    (d) Supplementary rules--(1) In general. This paragraph (d) provides 
certain supplementary rules necessary for the application of this 
section.
    (2) Definition of plan. For purposes of this section, the term 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) 
(including the mandatory disaggregation rule for portions of a plan that 
benefit employees of different qualified separate lines of business) and 
the permissive aggregation rules of Sec. 1.410(b)-7(d). Thus, for 
purposes of this section, the portion of a plan that benefits employees 
of one qualified separate line of business is treated as a separate plan 
from the other portions of the same plan that benefit employees of other 
qualified separate lines of business of the employer, unless the plan is 
tested under the special rule for employer-wide plans in Sec. 1.414(r)-
1(c)(2)(ii) for the plan year.
    (3) Employees of a qualified separate line of business. For purposes 
of applying paragraph (b) of this section with respect to a testing day, 
the employees of each qualified separate line of business of the 
employer are determined by applying Sec. 1.414(r)-7 to the employees of 
the employer otherwise taken into account under section 410(b) for the 
testing day. For purposes of applying paragraph (c) of this section with 
respect to a testing day, the employees of each qualified separate line 
of business of the employer are determined by applying Sec. 1.414(r)-7 
to the employees of the employer otherwise taken into account under 
section 410(a)(4) for the testing day. For the definition of testing 
day, see Sec. 1.414(r)-11(b)(6).
    (4) Consequences of failure. If a plan fails to satisfy either 
paragraph (b)(2), (b)(3), or (c)(1) of this section, the plan (and any 
plan of which it constitutes a portion) fails to satisfy section 401(a). 
However, this failure alone does not cause the employer to fail to be 
treated as operating qualified separate lines of business in accordance 
with Sec. 1.414(r)-1(b), unless the employer is relying on benefits 
provided under the plan to satisfy the minimum benefit portion of the 
safe harbor in Sec. 1.414(r)-5(g)(2) with respect to at least one of 
its qualified separate lines of business.
