Forward-looking statements
This presentation includes forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 regarding future events, conditions, circumstances and the future financial performance of BHP Billiton, including for capital expenditures, production volumes, project capacity, and schedules for expected production. Often, but not always, forward-looking statements can be identified by the use of the words such as “plans”, “expects”, “expected”, “scheduled”, “estimates”, “intends”, “anticipates”, “believes” or variations of such words and phrases or state that certain actions, events, conditions, circumstances or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved. These forward-looking statements are not guarantees or predictions of future performance, and involve known and unknown risks, uncertainties and other factors, many of which are beyond our control, and which may cause actual results to differ materially from those expressed or implied in the statements contained in this presentation.

Concluding observations
Slide 23
• No ‘one size fits all’ approach
• May be a combination of different methods
• Simpler might be better – qualitative vs quantitative
• Complex relationships are difficult to assess
– Available data and knowledge
– Understanding of interactions
– Synergistic CIA may be aspirational
• Manage expectations
• Robust management strategy can help mitigate risks
• Will still be difficult questions on proportionate responsibility
