"why don’t the largest shareholders make a takeover offer?"
Do you know who the largest shareholder is and how much of the company he and his family own? Also,
how much money is owed by HAO to said individual and his family?
It just would not happen.
Personally, I think that each holder has to decide whether he/she is going to go through what seems a slow and daunting process of selling under the current system, or hanging in there until there is so much demand for shares that they will become much easier to sell.
My current thinking is to hang-in there but, that may change, as I have been somewhat indecisive in the past - but now I am not so sure. lol
