Not that easy Joe. I own way more shares now than I did on Feb 15. I only get 10% on the shares I owned then. The math still has to be done. Also, if there is cash per share and merger deal (either on the table or in the works) you need to have the shares officially received. Also, the dividend procedure was initiated a long time ago, not yesterday. Also, whereas a buyout deal may be accepted this week, usually there is a later date involved when the deal actually closes based on both parties meeting certain conditions including installments of cash, transfer of records, etc.
So, the fact the the divi matter is being handled now actually points to the likelihood of a buyout and not the opposite. It is basically a prerequisite to the closing of a buyout deal.
