Authorized Shares information regarding what they could be for... http://www.investopedia.com/articles/basics/03/030703.asp#axzz1stscWDbP
Now just because a company can issue a certain number of shares doesn't mean that it is going to issue all of these shares to the public. Typically, companies will, for many reasons, keep a portion of the shares in their own treasury. For example, CTC may decide to maintain a controlling interest within the treasury just to ward off any hostile takeover bids.
[CTC is an example company]
If I saw potential for half a billion in sales I would definitely do this..
if between the 3 of them.. Brad, Jeremy, and Cory they have about 566million shares and there are currently 1.1Billion shares that are unissued into the O/S then that puts 1.66billion shares in those 3 guys hands.. or you can look at it as 66.4%(roughly) controlling interest in the company..
which means no hostile buyout on the cheap and cheap!!!!!
This is why I do not think dilution is happening.. If they are not careful and put to many shares on the open market some company could scoop them up for pennies on the dollar.. pretty smart move when you look at it from this perspective..
Then when its time and they have the cash on hand they can start a buyback program until they buy back enough shares to make the ones they have personally equal at a minimum 51%.. and cancel the remaining A/S ..... The only downside to this is that they would want the share price to remain as low as possible during this evolution so they can pay the minimal for the shares..
This would leave there gazillion shares untouched and unR/S and all of us the same... all while looking absolutely astonishing to shareholders and investors and driving the price "to da moon"
