Rebalancing November 5th, 2009

Friends Provident is being removed from the GCX on account of the company’s takeover by Resolution. Its place will be taken by Reed Elsevier. In a cross-sectoral comparison, the British media company stood out due to the particularly ambitious nature of its climate protection measures. These include appropriate management structures and clearly defined responsibilities, the introduction of a climate protection strategy, a voluntary commitment to reducing climate impacts and specific measures for achieving this goal, e.g. by purchasing green electricity and by offsetting its greenhouse gas emissions. The company has adopted various measures to improve the traceability of origin of the paper used in its media production. These measures are designed to ensure that only paper from legal sources is used.

Rebalancing March 20th, 2008

As part of the March 2008 rebalancing, the following companies were taken out of the Index: British Land, Coloplast, Liberty International, Northern Rock and Smith & Nephew. The reasons for their removal varied. Coloplast and Smith & Nephew had contravened the Index’s strict exclusion criteria. Coloplast failed to satisfy the social and environmental performance requirements for the medical technology industry and did not achieve “prime” status, the fundamental prerequisite for inclusion in the Index. In the case of Smith & Nephew, there was a violation of the “corruption” exclusion criterion. As regards Northern Rock, the nationalisation of the company was the key factor, and where British Land and Liberty International are concerned it was the restricted investment opportunities for German investors stemming from the “Real Estate Investment Trust (REIT)” legal structure.

New inclusions in the Index were the French pharmaceutical company Boiron, the US internet company Google, the US furniture manufacturer Herman Miller, the Swedish property company JM Group and the UK DIY chain Kingfisher.
