A-G
There are people here that have worked in mining, investment industry, research, construction, government, management, sat on BODs, etc that all have perspectives that come into play from time to time. There are very few people that 'KNOW' (have insider knowledge) but lots that can see similarities to other takeovers that they have been involved with and deduce/guess from there.
as to NOTs BOD's shares it's pretty evident that they went hunting for someone to help counter Wyloo's position so they had to make binding commitments before BHP would commit. What they have committed to is to tender their shares to BHP until BHP either wins or withdraws from bidding. If Wyloo or someone someone else wins the BOD gets to sell their shares to them. So the only real repercussion is that they can't support another bidder while BHP is in the game.
