I am intrigued by PB's statement in the Adani sale re simplifying the companies non core assets and getting on with our core business's. Does this mean that we are going to now focus entirely on UCG/GTL ? I suppose, the question I am asking is, what is considered non core? EG. Is the USA oil business non core or because it is paying its way, now core?? If the Arck is proved up, will it be considered a core asset or will it always remain a non core and hence 'for sale'.
The BIG question, that needs to be answered by PB, is what EXACTLY is our CORE assets/business? Is it possible that everything other then UCG/GTL will go under the hammer, under this new 'simplification' program that he has just announced????
