(a) Obligation of employer for payments for partial withdrawal for plan years beginning after the second consecutive plan year following the partial withdrawal year; criteria applicable; furnishing of bond in lieu of payment of partial withdrawal liability

(a)(1) If, for any 2 consecutive plan years following the plan year in which an employer has partially withdrawn from a plan under section 1385(a)(1) of this title (referred to elsewhere in this section as the "partial withdrawal year"), the number of contribution base units with respect to which the employer has an obligation to contribute under the plan for each such year is not less than 90 percent of the total number of contribution base units with respect to which the employer had an obligation to contribute under the plan for the high base year (within the meaning of section 1385(b)(1)(B)(ii) of this title), then the employer shall have no obligation to make payments with respect to such partial withdrawal (other than delinquent payments) for plan years beginning after the second consecutive plan year following the partial withdrawal year.
