On 15 August 2017 I posted a complete study on the GBG debt.
Summary of all these figures:
Loan maturing in 2030 is $US1.483132b - No liability because 26 November 2015 shareholders voted not to take liability
Other loans with differing maturity $US900m
Other loans with differing maturity $AUD244m
Now the $US900 was made up of $US400m, $US300m and $US200m.
All these have been rolled over and GBG has taken no liability apart from shares in KML.
So as of today only liability is $AUD244m plus $20m railway.
But $130m of that may allow Ansteel to increase shareholding in KML.
