About the KLD Global Climate 100 Index

         Launched on July 1, 2005, the KLD Global Climate 100^SM Index is a global index designed to promote investment in public companies whose activities demonstrate the greatest potential for reducing the current and future environmental impact of climate change.

         The Index includes 100 global companies that are leaders in providing solutions to climate change. The GC 100 constituents are allocated into three themes: Renewable Energy, Clean Technology & Efficiency and Future Fuels.

         The Index allocates 1% to each of the 100 securities in the Index to assure that large-cap companies do not unduly influence the performance. This provides higher exposure to small-cap companies and lower exposure to large-cap companies than a cap-weighted index. Each quarter, KLD rebalances the Index to bring each holding back to 1%. Additions made to the Index between rebalances are given the weight of the removed company at the time of the change.
