Under the Professionally Managed Account (PMA), all investors are the registered and beneficial owners of the investments held in a CHESS sponsored account.
If anything occurred to see InvestSMART cease operations, your investments would still remain in the name of the investor and/or entity listed as the Professionally Managed Account (PMA) holder.
You would then be able to facilitate the transfer of your investments to another CHESS sponsored account that you have access to and control over to continue to manage your investments.
