POO is AUD$70, page-86

I would suggest STO is basically a USD oil play as the majority of its debt is in USD.
Pa31, you seem to have made up your mind re STO & have a bias.
Saying things like $3bln of cash, when as you rightly point out that $1bln is available debt.
Sales growing, that is highly debatable in fact I would say sales will have dropped dramatically in actual dollars which is what counts right? Their sales were marginally higher in Q4 based off an oil price that is USD20/Bbl at least higher than it is now & more than that for the average of Q1 to date.
If prices remain as they are or are lower than now Q1 is going to be a shocker.
Have you considered the possibility of large write downs in your reckoning?

Despite all the talk of drill rig shut downs, stock piles are growing.
OPEC is pumping more oil each month, not less.

Longer term who knows, however I think some of the long term demand by vehicle growth in China or India will be replaced by new technology. China knows it can't keep polluting its air, India is probably yet to recognize this, but they will at some point. Anyway all of this is a long way in the scheme of things & in regards the situation STO currently faces.
