MRD - change in 5% owner status

[Guest Amy Keen]

A company was purchased, their 401k plan was frozen, and EEs began to participate in the new company's plan. No plan merger occurred. A 5% owner had received a Min. Distrib. under the old Plan. He is not a 5% owner under the new company. Does he have to continue to take MRDs from either or both plans? I can find nothing in my resource data, so I really appreciate any help.
