§ 4207.1 Purpose and scope.

(a) Purpose. The purpose of this part is to prescribe rules, pursuant to section 4207(a) of ERISA, for reducing or waiving the withdrawal liability of certain employers that have completely withdrawn from a multiemployer plan and subsequently resume covered operations under the plan. This part prescribes rules pursuant to which the plan must waive the employer's obligation to make future liability payments with respect to its complete withdrawal and must calculate the amount of the employer's liability for a partial or complete withdrawal from the plan after its reentry into the plan. This part also provides procedures, pursuant to section 4207(b) of ERISA, for plan sponsors of multiemployer plans to apply to PBGC for approval of plan amendments that provide for the reduction or waiver of complete withdrawal liability under conditions other than those specified in section 4207(a) of ERISA and this part.
