The Cleantech Index (CTIUS) adds design software and Asian wind power leaders to portfolio  

New York – September 29, 2008 - The Cleantech Group, LLC, in conjunction with the American Stock Exchange (AMEX), today announced the quarterly rebalance of its Cleantech Index™ (AMEX: CTIUS), effective September 29, 2008.

As part of the rebalance, Hong Kong-based China High Speed Transmission (Hong Kong: 658.HK) and Autodesk (NASDAQ: ADSK) will join The Cleantech Index.  They will replace Xantrex (XTX.TO) which is being acquired, Christ Water Technology (CWT.VI), and Comverge (COMV).

The changes will also be reflected in the exchange-traded funds (ETFs) based upon CTIUS: the PowerShares Cleantech Portfolio ETF (AMEX: PZD) and the KSM Cleantech ETF in Israel (Ticker: KSCUS.15). 

“We chose both companies for their growth, industry leadership, impact, and track record,” said Rafael Coven, Managing Director of Cleantech Indices for the Cleantech Group, LLC, and Index Advisor. 

California-based Autodesk is a leading provider of engineering design and prototyping software. Autodesk software enables architects, engineers, and industrial designers to conceptualize, create, and develop cutting-edge products and buildings rapidly, with less waste and, increasingly, to incorporate attributes of sustainability throughout the process. 

China High Speed Transmission, also called C-Transmission, is a rapidly growing and profitable manufacturer of large, mechanical power transmission equipment – particularly for wind-power turbines (over half its business), as well as marine propulsion and industrial applications. C-Transmission is well-positioned to take advantage of the global shortage of wind-turbine gear boxes and is currently developing models for 2.5 and 3.0 megawatt turbines.
