9 days from mail out of the rights documents is a suspiciously short period. I picked mine up from the post office today (30 May) & found the acceptance period had closed on Thu 28 May. Gandel mopping up cheap rights not taken up due to a deliberately short acceptance period? I'd have taken my rights up if it was a 14 day period which I'd have thought would be the absolute minimum reasonable acceptance period from mail out. Why aren't ASIC / ASX policing this?
