Cleantech Index (CTIUS) expands globally, adds 34 new companies

European leaders Gamesa and Novozymes, India’s Suzlon added to premier Cleantech Index

NEW YORK, June 30, 2008 The Cleantech Group™, LLC in conjunction with the American Stock Exchange (Amex), today announced its Cleantech Index™ (AMEX: CTIUS) added 34 companies to its portfolio of global cleantech leaders. The changes are also reflected in funds based upon CTIUS, including the PowerShares Cleantech Portfolio ETF (Amex: PZD) and KSM Cleantech ETF (Bloomberg: KSMCLNT: IT) in Israel.

“This expansion augments the Index’s coverage of the surging world demand for clean technology solutions in the face of resource and environmental challenges,” said Rafael Coven, Managing Director of Cleantech Indices for the Cleantech Group, LLC, and Index Advisor.

“Many of the best cleantech companies trade on foreign exchanges, so the additions ensure CTIUS remains the premier index reflecting the growth of cleantech across a broad range of industry sectors and geographies.”

The Cleantech Group’s Cleantech Index is the first, and only, equity index to offer investors and index licensees an easy, liquid, and costeffective way to track and invest in the broad cleantech category. Unlike indices that specifically track narrow sectors such renewable energy or water, the Cleantech Index includes leading companies from a broad range of sectors such as advanced materials, agriculture, transportation, manufacturing, in addition to energy efficiency, renewables and water.

“The broad cleantech category has shown superior performance than more volatile and narrowly defined vertical or sector products,” said Coven.

CTIUS is the industry gold standard upon which a growing range of financial products are based. In 2007, the Index outperformed the S&P 500 by 37.4 percent, over the last 12 months by 26.3 percent and in 2008 (through June 27) by 6.5 percent.

Non-US companies now comprise approximately half of the 76-company Index. The expansion includes 24 European companies, six from Asia and four from North America. Index companies must derive at least half of their operating profits or revenues from clean technology businesses, and pass 16 other quantitative and qualitative screens.
