method of takeover from bhp

Well, there has been alot of conjecture here on APG and it's future.

What I want to know is what would BHP have to do to take over APG. Is there more than one way to take over a company? What percentage of major shareholders do you need for acceptance of a takeover offer?

I do not want to see this happen. I would like APG to stay it's own entity with a string of royalties kicking back to the company directors and the patient shareholders who have held for years and could see the light. This company has some great technology, if it holds it's own the sky is the limit.

Cheers,
