Opportunities and Priorities Rio Tinto Alcan now more than ever has the strength and size to grow and develop worldwide. As we move towards integration, interesting opportunities will emerge within Rio Tinto for talent from Rio Tinto Alcan, and vice versa. We must continue to focus on our jobs, and to deliver day-to-day performance and results. Both Rio Tinto and Alcan have been recognized in putting employee safety at the top of the priority list. In this period of transition, we all must continue to actively contribute to maintaining the safety and health of those around us while ensuring we minimise our impact on the environment.

What to Expect over the Next 100 Days Integration is likely to be an intensive exercise, with many internal initiatives demanding our prompt attention. Some of you will be involved in shaping the new Rio Tinto Alcan. There will be changes but we will strive for a smooth transition. Everyone will be kept informed.

A New Beginning This is a time of new beginnings and opportunities -- and we acknowledge that it may feel emotional. With our shared values and commitment to excellence, together we will build an exciting future. Please make your new colleagues feel welcome as we make the transition to the new Rio Tinto Alcan.
