Not all of them on the board are squillionaires. Some are trying to make a name for themselves. The concern about the share price would be ensuring they do achieve fair value but I can see that some board members are also conflicted, so the votes of those members and their associates would presumably be disregarded in a related party transaction.

Just another thought - WGR and presumably another new investor (from that 5m day) may be in negototiations which would rule them out from further on market purchases without making full disclosure. Might be making the share price a little easier to control without that kind of buying pressure.
