Global Warming ELEMENTS ETNs Linked to Credit Suisse Global Warming Index Begin Trading Today

Business Wire, April 2, 2008

NEW YORK -- Credit Suisse announced the launch of ELEMENTS(SM) exchange-traded notes ("ETNs") linked to the Credit Suisse Global Warming Index, Exchange Series ("Global Warming ELEMENTS ETNs"). The Global Warming ELEMENTS ETNs are intended to offer exposure to stocks of companies that have an increased focus on products or services related to minimizing global warming. Global Warming ELEMENTS ETNs start trading today at the NYSE Arca under the symbol GWO.

The Global Warming ELEMENTS ETNs are linked to the performance of the Credit Suisse Global Warming Index, Exchange Series, an equally weighted index of 50 stocks that is rebalanced semi-annually. To construct this proprietary index, Credit Suisse identifies companies with business segments that are focused on minimizing global warming, both in the area of managing energy demand (companies that provide solutions for efficient energy consumption) and in the area of improving the supply of energy-efficient technology and environmentally friendly power (companies that limit CO2 production, are involved in electricity generation from renewable sources or create bio-fuels or fuel-cells). These companies are then systematically ranked according to the proprietary rules-based HOLT(TM) Scoring Methodology. The 50 highest-ranking stocks are selected for inclusion in the index.

"We believe that Global Warming is going to be one of the key investment themes of our generation," said Michael Clark, Head of Structured Retail Products for Credit Suisse in the Americas. "This product leverages Credit Suisse's proprietary HOLT(TM) Scoring Methodology, providing investors in the Global Warming ELEMENTS ETNs with easy access to the highest-ranking companies in this emerging sector."

"The proprietary HOLT(TM) Scoring Methodology is based on three categories," said David Holland, Managing Director and co-head of HOLT Valuation and Analytics. "The Operational category scores stocks according to corporate performance characteristics; the Valuation category scores stocks according to HOLT's DCF model and the Momentum category scores stocks according to metrics that objectively measure market sentiment."

Calculated by Standard & Poor's, the index is rebalanced every May and November, and is calculated as a total return index in U.S. dollars.

ELEMENTS ETNs are designed to track the return of specific market measures and seek to provide convenient access to strategies and markets that traditionally have not been readily available to individual investors. ELEMENTS ETNs can be purchased or sold through a broker or financial advisor.
