Thanks, however still not convinced mainly because they use "total revenue", why not gross revenue?
I know I am a bit pedantic, but when you have spent a lot of time reading contracts, you learn to look out for the details like this.
Also, what can they make a deduction for?
They exclude operating and maintenance expenses specifically.
Depends on how they define them.
What about admin expenses or any other type of expense they can dream up.
total revenue after recouping exploration and development expenses, or amortising them over the project?
I would still feel happier to see the details, which I doubt we ever will.
