§ 1364.
Liability on termination of single-employer plans under multiple controlled groups
(a)
This section applies to all contributing sponsors of a single-employer plan which has two or more contributing sponsors at least two of whom are not under common control at the time such plan is terminated under section 1341(c) or 1342 of this title, or who, at any time within the 5 plan years preceding the date of termination, made contributions under the plan.
(b)
The corporation shall determine the liability with respect to each contributing sponsor and each member of its controlled group in a manner consistent with
section 1362 of this title, except that the amount of liability determined under
section 1362(b)(1) of this title with respect to the entire plan shall be allocated to each controlled group by multiplying such amount by a fraction—
(1)
the numerator of which is the amount required to be contributed to the plan for the last 5 plan years ending prior to the termination date by persons in such controlled group as contributing sponsors, and
(2)
the denominator of which is the total amount required to be contributed to the plan for such last 5 plan years by all persons as contributing sponsors,
and
section 1368(a) of this title shall be applied separately with respect to each controlled group. The corporation may also determine the liability of each such contributing sponsor and member of its controlled group on any other equitable basis prescribed by the corporation in regulations.
