Possibly management realized that their business with AT&T, Nokia, etc is not going to get realized. Lots of wishful thinking, not experienced with dealing with big customers beyond their local market. They must have realized this already some time ago. Hence the acceptance of the Casa offer makes a lot of sense: they would not be able to get a better price for their stock anymore.
