The plan is a former ESOP that has been amended and restated as a profit sharing plan. Currently, the plan provides for distribution in either cash or employer stock with respect to participants. Do you think that it would be permissible under Section 411(d)(6) to amend the plan to remove the employer stock distribution option with respect to a "beneficiary" of a participant?

Never mind...I found my answer. See 1.411(d)-4 Q&A 2(a)(4).
