Who knows. They can walk away anytime, don't need the SEC to suspend it. The toxic lenders can sue them for any reason they want, including not getting their loan repaid and not being able to convert into shares. Shareholders can sue too. My guess is they hold on to this as long as possible to try and prevent that.
