The other element that you also should consider when it comes to the share holdings of the BOD, is that its worth nothing until they sell it.

It is not in David's interest to drive the company into the ground, the further the SP falls, the less and less his share is worth. If he had nefarious intentions, I would think he would want the SP as high as he can get it in order to generate as much unrealised gains as he can. So that when he was ready to sell, he makes more money.

RNU does not provide a dividend, so DC could own whatever percentage of the company you like and still be making nothing from those shares.
