It was interesting indeed. Regarding the coal sale the following loose comments were made by Justyn Peters:
- Coal sale could have happened 12 months ago at price X.
- Current sale prices being discussed are 10 times price X.
- Difference in price is $1 billion.
Based on those comments you can deduce that the current prices are approx $1.1Billion. I suggest listening to the webcast to make your intetpretations.
