Gday Melua,
Don't worry, BB has been keeping us informed while you were away ;)
I notice with the corp. debt that $220M is NZ. I would guess that it is NZ banks thst were holding Powerco as security and thus only the NZ debt is subject to the sweep.
A sale of DBCT could wipe out NZ debt and AUS corp. debt. No more sweep or 200bp until next rollover. ?
