mmmmm, I wonder"The Proposed Transaction represents Rio Tinto’s best and final all-cash transaction price of C$43.00 per share". This statement is interesting, in particular the words "all-cash". Could there be a subsequent offer that is not all-cash? Of course this assumes that a majority of the minority vote "NO". Also, what happens if the 17.5% dissent threshold is exceeded? Pentwater and SailingStone holdings are very close to that.
