A cash or deferred arrangement shall not be treated as a qualified cash or deferred arrangement unless—
(i)#
those employees eligible to benefit under the arrangement satisfy the provisions of section 410(b)(1), and
(ii)#
the actual deferral percentage for eligible highly compensated employees (as defined in paragraph (5)) for the plan year bears a relationship to the actual deferral percentage for all other eligible employees for the preceding plan year which meets either of the following tests:
(I) The actual deferral percentage for the group of eligible highly compensated employees is not more than the actual deferral percentage of all other eligible employees multiplied by 1.25.
(II) The excess of the actual deferral percentage for the group of eligible highly compensated employees over that of all other eligible employees is not more than 2 percentage points, and the actual deferral percentage for the group of eligible highly compensated employees is not more than the actual deferral percentage of all other eligible employees multiplied by 2.
(ii)(I)#
The actual deferral percentage for the group of eligible highly compensated employees is not more than the actual deferral percentage of all other eligible employees multiplied by 1.25.
(ii)(II)#
The excess of the actual deferral percentage for the group of eligible highly compensated employees over that of all other eligible employees is not more than 2 percentage points, and the actual deferral percentage for the group of eligible highly compensated employees is not more than the actual deferral percentage of all other eligible employees multiplied by 2.
If 2 or more plans which include cash or deferred arrangements are considered as 1 plan for purposes of section 401(a)(4) or 410(b), the cash or deferred arrangements included in such plans shall be treated as 1 arrangement for purposes of this subparagraph.
If any highly compensated employee is a participant under 2 or more cash or deferred arrangements of the employer, for purposes of determining the deferral percentage with respect to such employee, all such cash or deferred arrangements shall be treated as 1 cash or deferred arrangement. An arrangement may apply clause (ii) by using the plan year rather than the preceding plan year if the employer so elects, except that if such an election is made, it may not be changed except as provided by the Secretary.
