I'm curious as to how they've arrived at these figures, and whether these are expressed in AUD or USD.

If we take this year's US$878m statutory NPAT and simply adjust for financing costs as follows:
- add back (1 - 30%) x US$289 one-off refinancing
- add back (1 - 30%) x US$340m interest last year and
- subtract (1 - 30%) x US$156million for this years interest (4.58% weighted average on US$3,400m)

We would arrive at US$1.2bn NPAT. (A$1.2bn NPAT next year would imply considerable reduction in prices, production volumes, cost increases, appreciation of the Australian dollar or some combination of these).

The EPS figure also looks off, since $1.2bn earnings divided among 3.11bn shares equates to about 38c/share.
