CGW Invesco S&P Global Water Index ETF

Claymore Advisors, LLC today launched the Claymore S&P Global Water Index ETF (AMEX:CGW) on the American Stock Exchange. The Claymore S&P Global Water Index ETF tracks an index that is distributed equally between two distinct clusters of water-related businesses: water utilities and infrastructure, and water equipment and materials. �We believe that a global investing perspective effectively capitalizes on the breadth of opportunities that exist in the water sector,� said Christian Magoon, Senior Managing Director, Claymore Securities, Inc, an affiliate of Claymore Advisors, LLC. �S&P has created a robust and transparent index methodology that seeks to capture companies with significant revenues coming from water-oriented businesses,� he continued. �The launch of the Claymore S&P Global Water Index ETF allows investors to participate in this ever-important area of the market.� �Research has identified the global need for clean water, creating an equally global, emerging opportunity for investment. We believe that our ETF offers investors a unique opportunity to access this investment theme by investing in foreign and domestic stocks,� Magoon said. �Unlike other water-related investment products, the Claymore ETF provides liquid exposure to the leading publicly listed companies from developed markets in the global water industry.� The Claymore S&P Global Water ETF (AMEX:CGW) seeks investment results that correspond generally to the performance, before the respective Fund�s fees and expenses, of an equity index called the S&P Global Water Index. The index is comprised of 50 equity securities selected from a universe of companies listed on global developed market exchanges and based on the relative importance of the global water industry within those companies� business models. The index is designed to have a balanced representation from different segments of the water industry consisting of the following two clusters: 25 Water Utilities and Infrastructure companies (water supply, water utilities, waste water treatment, water, sewer and pipeline construction, water purification, water well drilling and water testing) and 25 Water Equipment and Materials companies (water treatment chemicals, water treatment appliances, pumps and pumping equipment, fluid power pumps and motors, plumbing equipment, totalizing fluid meters and counting devices) based upon Standard & Poor�s Capital IQ (�CIQ) industry classification. Companies included in the Index have market capitalizations ranging from US$250 million to US$25 billion and the Fund will normally invest at least 90% of its total assets in common stocks and ADRs that comprise the Index. The Index is rebalanced annually.

Risk Considerations: Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. Investment Risk: an investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Equity Risk: a principal risk of investing in the Fund is equity risk, which means that the value of the securities held by the Fund will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. Risk of Concentrating in the Water Industry: Adverse developments in the water industry may significantly affect the value of the securities held by the Fund. Companies involved in the water industry are subject to environmental considerations, taxes, government regulation, price and supply fluctuations, competition and water conservation. Foreign Investment Risk: the Fund�s investments in non-U.S. issuers, although limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including, among others, greater market volatility than U.S. securities, currency risk and less complete financial information than for U.S. issuers among other risks. Small and Medium-Sized Company Risk: investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in more established companies. These companies� stocks may be more volatile and less liquid than those of more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market. Non-Correlation Risk: the Fund�s return may not match the return of the Index for a number of reasons including, but not limited to, operating expenses not applicable to the Index and costs in buying and selling securities to reflect changes in the composition of the Index. Additionally, the Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Replication Management Index: unlike many investment companies, the Fund is not �actively� managed. Therefore, it would not necessarily sell a stock because the stock�s issuer was in financial trouble unless that stock is removed from the Index. Issuer-Specific Changes: the value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. Non-Diversified Fund Risk: the Fund is considered non-diversified and can invest a greater portion of assets insecurities of individual issuers than a diversified fund, which may result in greater fluctuations in share price. Please read the Fund�s prospectus for more detailed information. Claymore ETFs are listed on the AMEX the same way as shares of a publicly-traded company. Claymore ETFs can be purchased through most brokerage accounts. They can be bought and sold throughout the day on the AMEX during normal trading hours. The Fund issues and redeems shares at NAV only in large blocks of 200,000 shares (each block of 200,000 shares is called a �Creation Unit�) or multiples thereof. Only broker-dealers or large institutional investors with creation and redemption agreements, called Authorized Participants (�APs�), can purchase or redeem these Creation Units. Deliveries of Fund securities to redeeming investors generally will be made within three business days. Due to the schedule of holidays in certain countries, however, the delivery of in-kind redemption proceeds may take longer than three business days after the day on which the redemption request is received in proper form. In such cases, the local market settlement procedures will no commence until the end of the local holiday periods. See the Fund's SAI for a list of the local holidays in the foreign countries relevant to the Fund. Investors buying or selling ETF shares on the secondary market may incur brokerage costs and other transactional fees. Shares of ETFs will fluctuate in price due to daily changes in trading volume. At times, shares may not have a high volume of trading. Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund.
