The annual plenary session was held in Oslo, and Marathon Oil and Anglo American joined the group at this meeting. Newmont replaced ChevronTexaco and Human Rights Watch replaced Amnesty International on the Steering Committee as part of the annual Committee membership rotation. Additionally, two working groups were established, one to review the process for sharing information about progress with implementing the principles, and the other to review the structure of the Voluntary Principles process and identify opportunities for improvement. Both working groups consist of representatives from member companies, governments and NGOs. Next year’s plenary meeting will be hosted by the UK government in London in January 2006.
