Aluminium CSG
Introduction• Aspiring to be the best aluminium
company in the world:The scorecard
– Zero harm in HSEC– Lowest unit cash costs– Growth and Sustainability– Size / Materiality– Value– Cash generation
• How we measure up– Zero harm is the focus– Lowest metal & alumina system cash
costs – but we can and will improve our relative advantage
– Strong growth track record, but industry consolidation makes future M&A value based growth challenging
– No. 2 in 3rd party aluminium (after RusAl) & No. 4 in 3rd party alumina (after Alcoa, Chalco and Glencore)
– No. 4 in ROC in calendar 2002 after Comalco, Alcoa & Chalco
– NPV large and growing

The KPI Process Map lies within a gener ic negative feedback loop, and identifies “defects” so that they can be corrected ( targets
change over time to reflect continuous improvement)
