29 U.S. Code § 1390 - Nonapplicability of withdrawal liability for certain temporary contribution obligation periods; exception

(a) An employer who withdraws from a plan in complete or partial withdrawal is not liable to the plan if the employer—
first had an obligation to contribute to the plan after September 26, 1980,
(2) had an obligation to contribute to the plan for no more than the lesser of—
6 consecutive plan years preceding the date on which the employer withdraws, or
the number of years required for vesting under the plan,
was required to make contributions to the plan for each such plan year in an amount equal to less than 2 percent of the sum of all employer contributions made to the plan for each such year, and
has never avoided withdrawal liability because of the application of this section with respect to the plan.
(b) Subsection (a) shall apply to an employer with respect to a plan only if—
the plan is amended to provide that subsection (a) applies;
the plan provides, or is amended to provide, that the reduction under section 411(a)(3)(E) of title 26 applies with respect to the employees of the employer; and
the ratio of the assets of the plan for the plan year preceding the first plan year for which the employer was required to contribute to the plan to the benefit payments made during that plan year was at least 8 to 1.
Editorial Notes

2006—Subsec. (b)(1) to (4). Pub. L. 109–280 redesignated pars. (2) to (4) as (1) to (3), respectively, and struck out former par. (1) which read as follows: “the plan is not a plan which primarily covers employees in the building and construction industry;”.

1989—Subsec. (b)(3). Pub. L. 101–239 substituted “Internal Revenue Code of 1986” for “Internal Revenue Code of 1954”, which for purposes of codification was translated as “title 26” thus requiring no change in text.
