What does it Mean? A privilege, sold by one party to another, that gives the buyer the right, but not the obligation, to buy (call) or sell (put) a stock at an agreed-upon price within a certain period or on a specific date.
In addition to the stocks it issues to investors and executives, many companies offer stock options and warrants. These stock options and warrants are instruments that give the holder a right to purchase more stock from the company's treasury. Every time one of these instruments is activated, the float and shares outstanding increase while the number of treasury stocks decrease. http://www.investopedia.com/articles/basics/03/030703.asp
imo - This says to me that the shares actually purchased will increase the O/S but not the float as yet. According to the link I posted last night, these purchased shares are restricted for 6 months. So just like the other shares the officers hold and have held now for almost 1 1/2 years, they don't enter the float until they are sold( or perhaps when they file what was known as a form 144, to remove the restriction) In other words that part is still a non-issue.
