So hopefully I got your attention. A medical practice agreed to convert their plan from RK A to RK B. The plan has several self-directed brokerage accounts that are offered through RK As recordkeeping system so everything is (was) working fine. Upon notification that the plan was leaving RK A told the Plan Sponsor that all assets in the SDAs would need to be liquidated and the cash transferred to the core accounts to then be liquidated and transferred to RK B. Dr. X, who is a partner / member / owner, but not a majority owner, refused to liquidate his positions because he has a specific Russian ETF that is illiquid and represents a $250k unrealized loss. The fund is actually in the process of being liquidated by the fund company, but there is no known timeframe for when this process will end. The Plan Sponsor still wants to convert from RK A to RK B but is at a standstill due to Dr X's refusal to liquidate his account. Dr. X is not eligible for in-service withdrawals so he can't distribute in-kind shares to an IRA. We have politely told him that he is potentially creating a fiduciary issue since he is taking his personal account into consideration and not doing what is in best interest of plan and other participants. Can anyone chime in with thoughts on how to proceed? If at all? Maybe I shouldn't want this plan, but the rest of the decision makers are great and they are VERY frustrated with Dr. X.
