DF I think you will find the company is talking about the 'here and now' situation. However all companies run projected forecasts (especially this one) to see if there is a possibility of fighting there way out of the situation they are currently in.
It is a 'no brainer' that the carbon tax is yet another nail in the coffin when you are already running at a loss.
The other side of the coin, with that statement, is that the company also has other plants/interests that have been propped up by government subsidy, so you don't bite the hand that feeds you!
