Plan Termination after stock aquisition

Facts: Clients company is acquired via stock sale, but TPA wasn't made aware until two months later. Therefore, there were no actions taken to terminate the plan.

Question: Since they can't really terminate the plan retroactively, what can be done at this point?

Does a stock sale mean the plan is terminated?  Is there anything in the sale agreement that requires the termination of the plan?

Do they want to terminate the plan?  I agree with David unless something in the sales agreement requires it they can keep the plan.  It was a stock sale so the company never went out of existence.

Not enough info.  Of course, we start with "what does the acquirer want to do?"  Since you say it was a stock sale, in fact the company was not "acquired", there was just a change in who owns the stock.  Therefore, the same issues that would always apply if your client called you today and said I want to terminate the plan apply.  Nothing special because it is still the same employer with no change.
