(3) Distributions during last 5 years taken into account For purposes of determining—
(A) the present value of the cumulative accrued benefit for any employee, or
(B) the amount of the account of any employee,
such present value or amount shall be increased by the aggregate distributions made with respect to such employee under the plan during the 5-year period ending on the determination date. The preceding sentence shall also apply to distributions under a terminated plan which if it had not been terminated would have been required to be included in an aggregation group.
(4) Other special rules For purposes of this subsection—
(A) Rollover contributions to plan not taken into account Except to the extent provided in regulations, any rollover contribution (or similar transfer) initiated by the employee and made after December 31, 1983, to a plan shall not be taken into account with respect to the transferee plan for purposes of determining whether such plan is a top-heavy plan (or whether any aggregation group which includes such plan is a top-heavy group).
(B) Benefits not taken into account if employee ceases to be key employee If any individual is a non-key employee with respect to any plan for any plan year, but such individual was a key employee with respect to such plan for any prior plan year, any accrued benefit for such employee (and the account of such employee) shall not be taken into account.
(C) Determination date The term “determination date” means, with respect to any plan year—
(i) the last day of the preceding plan year, or
(ii) in the case of the first plan year of any plan, the last day of such plan year.
(D) Years To the extent provided in regulations, this section shall be applied on the basis of any year specified in such regulations in lieu of plan years.
(E) Benefits not taken into account if employee not employed for last 5 years If any individual has not performed services for the employer maintaining the plan at any time during the 5-year period ending on the determination date, any accrued benefit for such individual (and the account of such individual) shall not be taken into account.
(F) Accrued benefits treated as accruing ratably The accrued benefit of any employee (other than a key employee) shall be determined—
(i) under the method which is used for accrual purposes for all plans of the employer, or
(ii) if there is no method described in clause (i), as if such benefit accrued not more rapidly than the slowest accrual rate permitted under
section 411(b)(1)(C).
