RE:RIO--WRN DEAL PROVISIONS (SPECULATION)Arrow - i think you are spot on! In fact i think even you numbers are in the ballpark...
and the difference of final outcome of $4.84 and $8.34 between now and the final agreement will be how warm and fuzzy Rio feels about the pain and effort to get thru permitting, their interaction with FN's, to some extent what happens with metals between now and then, etc.
personally i'd be ok with $4.84 usd across 285k shares ...i'm not looking or hoping for > $10 usd/share like many on this board...
