Actually, weren't they paid in common stock, valuing that dollar amount you posted?
If so, then Qualitystocks.com is the one responsible for sending this into the toilet, as they have likely been dumping their payment shares into the open market.
The question becomes, why did GRDB utilize such a sleezy operation??? They may have had an ulterior motive, such as buying back a large chunk of stock at a much lower PPS. They probably didn't expect the share price to hit $4 quite so quickly, did they???
