In doing the final accounting of the old plan, the prior TPA made an error. Basically, one of the valuable employees got a sizeable chunk of the Doc's rollover account. She subsequently fell on hard times and took a distribution of the rollover balance in her new account and spent the money. The error was discovered by prior TPA after the money was distributed by the current TPA.
The participant can't pay back the excess amount to the plan and there is a dispute (of course) as to who should pony up to make the Doc's account whole (seems pretty clear to me!). Doc and prior TPA are trying to come to an equitable solution so the participant can pay the $ back. Prior TPA suggested that the plan issue a promissory note from the Doc's account to the participant. The Doc's account could hold the note as the participant pays back the money with interest.
I know that the Prior TPA should pay the amount that the Doc's account is short and go after the participant outside of the plan (or perhaps have the participant make installments to them rather than the plan). I know what the appropriate correction should be but, would the loan from the Doc's account be a prohibited transaction assuming the Doc would even agree to this? I have tried reading about PT's and the exemptions for participant loans but all the information I read talks about loans from the participant's own account rather than from someone elses account. Help?
