Hard to say precisely. IVFH paid 10 million shares valued at $14 million to buy the company. You may remember how one of the geniuses that writes for Simply Alpha called it a steal. The question is how much of the company did he own when Sam bought it.
I have a guess but it is strictly a guess. I can only tell you that I believe it is measured in millions of shares, not hundreds of thousands. What I cannot know is the first digit on that amount. I do not remember seeing share detail when IVFH bought FD. I only remember the price and that bit of classic wisdom from the SA author.
Perhaps we can have the 'guess the shares the former FD owner can dump on the market' contest? Of course if his shares are still restricted, he can't dump anything. Hard to imagine one would settle a lawsuit and not get the right to sell millions of shares at a minimum.
