Study the various press releases.  There was a strong sense from the CMED crowd they would get $43 cash. It was worded in a very, very misleading way and the "strategic shareholder" firm Laurent Hill answering questions were telling people "yes, you will get full $43 cash".  It's quite possible some people still think that's true.  I spend hours plotting all of this in Excel because I had little faith.

The math did not make sense and even today, the last press release confirms via math that ACB has kept $5.40 per share in cash so there is a small chance people will get a bit more
