Gamemaster Corporations

I recently bought 1 share of a company... only to find out that now I'm the majority shareholder!

Turns out that if the company is 100% owned by investment portfolios, it becomes a gamemaster company, at least, in terms of control.

As such I have all sorts of questions about this. I'd like the general rundown, so I wont ask too many specifics. I'm hoping someone wrote a guide at some point that I can be pointed to.

That is right. Investment funds cannot control a corporation. Interestingly, with only 1 share controlled of such a corp, you can close it. Chances are, all of the investment funds with ownership in that corp are automated. This is one reason you should consider turning off automated control of your investment fund portfolio. If you decide to retain the corp, you will only benefit on profit sharing distributions proportional to your ownership %.
