No it doesn't Scrag18,
I would imagine the worst possible scenario would be that Fortis would sell off its subsidiaries but not their assetts.
Also it is under 5% of the comapny and not like Opes Prime where many companies had 30% + shares owned by Opes Prime.
Here is a pdf from Fortis website explaining their situation.
