Good post and great action you took. Good points made, I'm sure there are many more issues that can be brought up. Law firms are probably looking at this anyways.
I hope the SEC does something, but who knows. I think the only thing that may mean something would be a lawsuit.
You forgot to mention that buy assigning this ridiculous premium to the already overvalued (according to most of the analysts) EXPE, Diller artificially boosted the value of the 54% EXPE stake that USAI already owns.
And he did it just when all the fundumentals, technicals, and analysts were clearly pointing in the downward direction for the EXPE shares.
