lets look at this your way. This is hypethetical only but you can correct me as needed.
There are appx 720,000,000 shares currently outstanding.
Offor has appx 310,000,000 of them for 43% of the company.
The rights offering is for 246,486,285 (why the exact odd number?)
Offor can fully participate for 103,200,000.
That leaves 143,286,285 for the rest of the investors.
The next biggest shareholder has appx 60,000,000 shares
That gives them 20,000,000 that will fully subscribe them.
That leaves 123,286,285 shares to the rest of the shareholders.
My guess is that the rest of the share holders will take the
23,286,285 shares. That leaves 100,000,000 shares for the over subscription. I think the over subscribers will take 10,000,000 of those as money will be real tight to buy any more. That leaves
90,000,000 shares going to Offor. Now if you take the previous outstanding shares of 720,000,000 and increase them to include the subscription that has now taken place the total shares outstanding will be 966,486,285 of which offor will now have 503,200,000 making him 52% owner of the company! All done legally. Could that be the plan?
