Bpooa expired 30/6/07
They were underwritten,so if you didn't convert they had the right to convert remainder.
Bpoob expire 31/3/10 with exercise price of 5c.
If bpo are anywhere near 5c i feel these will be underwritten as well.It would represent about 20% of bpo if converted.Bpo looks like it's ready to go back to 4's.
