I'm not sure that I understand your question, borredo. Are you asking if "a group of shareholders" with a combined total of 13% of the total number of outstanding shares would have any leverage to influence the board of directors of a company? I guess it would depend on the quality of the company, wouldn't it seem that way to you?
Do you think Warren Buffet would be concerned if 13% of the shareholders of Berkshire Hathaway grouped together to send in a letter to the board of directors? Would Warren take that seriously? I think the quality of both the man and his company would dictate that he would, however, it is probably also true that 13% of his shareholders have only ever grouped together to plan outtings and events for their next shareholder meeting.
I'd like to think that PTSC shares that same quality.
