Are you talking $AUD or $US.
If $US94.60, then GBG should be making some money, but not $US30 as KML still has a debt of $US1,481,000,000 ($US1.481billion).
The interest rate is unknown - but I would guess 4% pa at the very minimum, that $US60m pa. If interest rate 8%pa then $120m pa interest costs.
[Aside in 2016FY FMG had $6.1b debt and paid $3.20 per tonne interest cost on 165m tonnes of exports = $528m interest which equates to 8.66% interest rate approx. - refer to

Also maintenance costs are high.
But KML had not paid interest for a number of years - unless the rolling loans have been used to pay the interest.
We are all mushroom people. In the dark and feed ....
Interesting that last ship booked is set to sail 19 January without any more in line - unusual, but may book some more ships in next couple of days. Will keep you posted.
