From the recent filing. 2 billion and change. I believe it's as of May 12, 2015. Insiders hold over 1.5 billions.
The current increased of 800 millions, insiders seemingly took 600 millions of off that. That alone speaks the volume.
Then we just have $2 million market caps but tons of customers list. The goodwill and logistics alone should be worth in millions. Then we have china deal ... expect 2015 revenue of $15 to $20 millions.
