Basically there are a few terms you should know. They are AS (Authorized shares), OS (Outstanding Shares), OS Fully diluted, Insider Shares, and Float. Basically, the AS is the amount of shares a company can issue as stated in it's articles of incorporation. The OS is the number of shares already issued and outstanding. OS Fully diluted is the maximum number of shares the company in contractually obligated to issue to cover all obligation such as preferred shares, warrants, notes payable, etc but have not been issued yet. The amount of shares held by insiders are just that, they are people that usually work for the company and hopefully their shares are locked up so they can not be sold readily, like in our case. Finally, the float is what is left after you take the OS and subtract what the insiders control. In our case, as of our last 10-Q, we have about 156 million shares OS and insiders control about 121 million shares so that leaves us a float of about 35 million shares that are available for trading purposes. Our goal is to buy and hold on to the entire float so when the company creates demand, there is almost no supply, forcing the price per share (PPS) up.
I hope this helps. Good luck to you.
