The insider open market buys were financed by "free" share grants to the same key executives/insiders that were then sold and repurchased on the open market.
That makes the insider shares accumulated at a net zero cost to executives and in no way endorses insider buying.
It actually is dishonest and unethical but that is the norm with MSLP as 3 key executives did not claim several million dollars in income on either their W-2 or tax forms in 2012. This is a felony and they are attempting to claim ignorance.
The primary focus of the formal SEC investigation in MSLP is the massive insider selling of shares and the lack of reporting and accounting. Go do some research into the $ millions that were granted to Pyatt, sold and not reported.
