I looked through the relevant Code and the Plan document and wanted to run one more thing by you. The termination section of the plan essentially provides that the plan freezes (no new contributions, etc.) once the board elects to terminate but also states that all other provisions of the Plan remain in force.
The Plan further provides a Participating Affiliate, which the other two companies would be, may withdraw from the Plan and the Trust without the Plan Sponsor i.e. the sold company's written consent. The Participating Affiliate just has to adopt a plan and trust identical to the original one and then the assets of the Trust allocable to Employees of the Participating Affiliates are transferred to the trust adopted by the Participating Affiliates.
Based on these two sections, it would seem that we could accomplish what we want to (i.e. move the employees of the two companies to the new plan). It would also seem the employees remaining with the company terminating the plan would be able to receive a disbursement since they will no longer be employees of the two companies (and continuing control group) starting the new plan.
Am I interpreting this correctly?
