Officers and Director

My team have been carrying out further DD on Directors and Officers of the company. It appears that the highest paid is Santos Andrei, whom does not have a shareholding. I would have thought that any officer holding a position for this length of time and receiving a large salary should have purchased a good lump of shares. If he has faith in the company, why has he not purchased?  This will annoy certain holders and certainly shows lack of commitment on his part.
