Regarding the common, I said 50cts, they paid 30cts. The majority accepted, not much you can do about that. They were able to screw the minority dissenting holders (including yours truly).
What I fail to see here is why they would offer $16 now, if $25 is four or five years into the future (and that assuming that $25 ever materializes). Because they will make 10% on their $16 bucks a share? These are NOT 10% return investors, they aim for more. This is private equity, and the clock is ticking.
