I'm sure that the Hunsman's along with their lawyers weight all the options before settlement. This thing could have dragged on for years. If the jury gave them a large settlement, the banks most likely would have appealed it all the way up the line. This way they received much needed cash & loans on favorable terms. Why Wall street took such a dim view is beyond my comprehension.
I refer you to the first post in this string. "Wall Street" has not taken a "dim view" of the settlement from HUN's perspective, Wall Street has taken a dim view of the settlement form its own perspective...hopes for a trade of a lifetime windfall were dashed, and it seems that a lot of selling shareholders held those hopes.
I do not believe that a new buyout is in the works...it's the wrong point in the cycle, but I do believe that the Huntsmans took this settlement so that they would be free to sell the company at the time of their choosing without the complication of an ongoing appeals process.
