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

China – Global Market Implications

• Metal• Continuing to grow strongly and will continue to grow• Despite strong consumption growth – a net exporter

• Alumina• Not keeping pace with metal growth• Where will it come from / will it be available?

The KPI / Value Driver TreeThe KPI Process Map is designed to :• Measure deviations from target (KPO’s)• Analyse the deviations to determine corrective actions (KPD’s)• Measure the economic impact on EBIT by not correcting variances

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)
