I have to be honest with you 4 and 5 are losing me.. i have never had to do any calculations like that..
I understand that if a institutional investor buys 30% of the company at X price and they dilute then the same investor will have to purchase a certain amount of shares to regain their 30%.. that part i understand and basically the % ownership would be virtually unchanged as long as the investors were able to regain the % they previously had.. which would lock up more common shares with these investors and cause a pps climb from these levels to have a greater impact on their investment due to high volume of shares..
So with the numbers i put out the institutional investors could possibly own a majority of the company causing them to have a huge stake..
i do not remember lawsuit and manipulation of stock though..
