CUT Invesco MSCI Global Timber ETF

Claymore Securities Inc., the third fastest-growing exchange-traded fund provider in 2007*, today announced that its Claymore/Clear Global Timber Index ETF (AMEX: CUT) continues to gain momentum as investors increasingly look for possible alternatives in today�s volatile markets. Launched in November 2007, CUT was the first U.S.-listed global timber ETF to offer investors exposure to the timber asset class. Timber has traditionally been an asset class valued by institutional investors such as endowments and pension managers for its diversification benefits. �Timber investments tend not to move in the same direction as traditional equity investments,� said Christian Magoon, President of Claymore Securities and Head of its ETF Group. �Since its launch, CUT has gained wide acceptance�investors are increasingly recognizing that timber may provide a unique diversification.� With $52 million in assets under management as of June 23, 2008, CUT is the world�s largest and most liquid ETF providing retail investors access to timber, according to Bloomberg data. The Claymore/Clear Global Timber Index ETF seeks investment results that correspond generally to the performance, before the Fund's fees and expenses, of an equity index called the Clear Global Timber Index (the �Index�) (http://www.clearindexes.com/timber). Stocks in the Index are selected from the universe of global timber companies and defined by Clear Indexes LLC, the index provider, as firms that own or lease forested land and harvest the timber from such forested land for commercial use and sale of wood-based products, including lumber, pulp or other processed or finished goods such as paper and packaging.

Risks and Other Considerations: There can be no assurance that the Fund will achieve its investment objective. An investment in the Fund is subject to investment risk, which is the possible loss of the entire principal amount that you invest. There is a risk that the value of the securities held by the Fund will fall due to general market and economic conditions. The market value of securities of global timber companies may be affected by numerous factors, including, but not limited to, events occurring in nature, international politics, global competition, supply and demand issues and environmental, safety or health laws and regulations. As the Fund is focused in the global timber industry, it may be subject to more risks than if it were broadly diversified over numerous industries and sectors of the economy. The Fund�s investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including, among others, greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. Investment in securities of issuers based in developing or �emerging market� countries entails a heightened degree of risk. Non-diversified ETFs invest a greater portion of assets in securities of individual issuers than a diversified ETF and therefore, may cause greater volatility. ETFs are not �actively� managed and would not necessarily sell a stock because the stock�s issuer was in financial trouble unless that stock is removed from the index. ETFs are subject to potential tracking errors and returns may not match the returns of the index. ETFs that focus on small and medium-sized companies generally experience greater price volatility and risk than investing in more established companies. In addition to the risks described above, there are certain other risks related to investing in ETFs. Please read the prospectus for more detailed information.
