Read the Announcement, clearly all are not holding until maturity. Not a bad option to buy some of these Notes if anyone here is cashed up, they pay good returns.
No, unfortunately there is no real positives with the CN's as they are a liability in every sense of the word, and a cost that Shareholders don't need. The only positive thing I can think of is our share price will rise a bit when / if we are finally rid of the CN's by paying them out in full, but we may need to take on a loan to do this.
