Almost half the outstanding shares traded today at $8.50 or below. Assuming the buyer had the cash to do the deal they are probably buying in the open market and have acquired enough shares to control the vote.
We will know for sure when over 5% buyers have to report.
BTW, most of the transactions took place slightly below the offer price. That was probably the funds getting out. They would take a penny or two haircut to get their money now instead of having to wait until the end of the year. If I am correct then the party is definately over.
