My understanding is that they aren't trying to send a message - they are forced to sell.
Originally they had a sell limit of 45c and then dropped it to 42.5c. They were dribbling out small parcels at a time. They have been looking for someone to take the lot for a few months now.
Not sure what to read into it all in terms of what it means for the bid. I can't see it being good news for the bid, but then again, a forced seller can't wait for a bid to eventuate. The result is probably that we can't read much into it at all other than that it will be an annoying overhang until someone takes it off their hands.
