CHART: BHP before and after spin-off

BHP Billiton announced in August a plan to create an independent metals and mining company based on a selection of its aluminium, coal, manganese, nickel and silver assets.

This chart from the Melbourne-based company's 2014 annual report shows just how much the structure of BHP Billiton has changed since 2005, with iron ore, and oil and gas playing a dominant role and potash set to become a significant contributor in the future.
