"This is a request for information (RFI) to inform PBGC on issues arising from arrangements between employers and multiemployer plans involving an alternative 'two-pool' withdrawal liability method. PBGC seeks information from the general public and all interested stakeholders, including multiemployer plan participants and beneficiaries, organizations serving or representing retirees and other such individuals, multiemployer plan sponsors and professional advisors, contributing employers, unions, and other interested parties about these arrangements, including the various forms these arrangements may take, the terms and conditions that apply to new and existing contributing employers who enter into such arrangements, and the benefits and risks these arrangements may present to multiemployer plans and their participants, employers, the multiemployer pension insurance program, and other stakeholders in the multiemployer system."
