Search 29 U.S.C. § 1364 : US Code - Section 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.
