I had a look at the prospectus and there is this rather inocuous piece in there;

BBIPL may require the Trustee to execute on behalf of itself and all Holders such documents as BBIPL considers necessary or desirable for the purposes of the subordination of the Guarantee to any indebtedness or guarantee of BBIPL which ranks ahead of claims of Holders.

this whole mess is not very straightforward and I can see why the Australian is calling these notes "complex". I really hope the BNBG notes are 10% of face worth of hassle to BBIPL
