Dan Akerson bought 25,000 shares from the open market for $20.35 on August 7, 2012.
Thomas Schoewe bought 3,800 shares from the open market for $26.05 on March 4, 2012.
Thomas Schoewe also bought 3,845 shares from the open market for $25.94-5 on Nov. 5, 2012.
Now, here's another little bit of trivia for you. Typically any board member (for any company) has a minimum stock retention requirement. Thomas Schoewe has only been a BOD member since 11/14/11. He probably only has a year to acquire his minimum number of shares and today's date is 11/14/12. What a coincidence! I would be willing to bet that his minimum requirement is 7,500 shares and since last week he now owns 7,645 shares.
His buying stock probably has nothing to do with whether he thinks it's a good buy, but if he wants to continue to be a board member he has to have 7,500 shares and he has now fulfilled his requirement.
Ackerson, on the other hand, has been a board member since July, 2009 so that's NOT the situation with him.
The only other open market sale for the past 6 months was two individuals selling 8,521 shares of stock on the open market in June and July, 2012. So, Ackerson bought 25,000 shares, the other two individuals sold 8,521 shares giving the net difference of 16,479.
As far as the other transactions, think of those as compensation. They are either zero based shares or options they get in the form of compensation. In order to get cash, they have to sell them in a non market transaction, that's all those are.
So, in summary, the only insider trades I would look at is the Ackerson trade, which was a buy, along with the other two smaller sells.. Don't be tricked by all the noise on these insider trading sheets. You have to have some understanding about what you are reading.
