United States Commodity Funds LLC Lowers Fees of United States Copper Index Fund (CPER)

ALAMEDA, Calif., May 29, 2012 /PRNewswire/ -- United States Commodity Funds LLC (USCF) announced a voluntary reduction in a portion of its management fee for the United States Copper Index Fund (CPER).  As of May 29th, 2012, the management fee will be reduced from 0.95% to 0.65%.  USCF anticipates that the waiver will remain in place through March 31, 2013.  This reduction is voluntary, and may be terminated or modified prior to March 31, 2013, with the approval of USCF's Board of Directors.

Chief Investment Officer John Hyland states, "With CPER, we tried to design both a useful tool for investing in copper exposure over the long term, as well as a useful tool for trading copper exposure over the shorter term. We think that offering it with lower expenses will help generate economies of scale for both trading and investing."

The United States Copper Index Fund ("CPER") is an exchange-traded security that is designed to track, in percentage terms, the price movements of the SummerHaven Copper Index Total Return (SCI).  CPER issues units that may be purchased and sold on the NYSE Arca.

United States Copper Index Fund tracks a portfolio of Copper futures contracts traded on the Comex exchange.  Copper is a metal that has global and widespread uses across multiple industries. Copper futures contracts are one of the most actively traded of the metals futures contracts and serve as the single commodity in the SummerHaven Copper Index.

United States Commodity Funds LLC manages 11 commodity exchange traded products, including the recently launched United States Agriculture Index Fund.

This material must be preceded or accompanied by a prospectus. Please read it carefully before investing or sending money.

Commodities and futures generally are volatile and are not suitable for all investors. CPER is speculative and involves a high degree of risk. An investor may lose all or substantially all of an investment in the CPER. Funds, such as CPER, that focus on a single sector generally experience greater volatility.

CPER is not a registered investment company so you do not have the protections of the Investment Company Act of 1940, as amended, and CPER is not subject to regulations thereunder. Accordingly, you do not have the protections afforded by that statute which include, for example: (1) controls over activities of an investment company's investment adviser; (2) an express private right of action for shareholders; (3) restrictions on transactions between the fund and the adviser; (4) restrictions on investments; (5) regulation of adviser services and fees; and (6) capital structure requirements, including restrictions on debt.

Investing in commodity futures interests subjects CPER to the risks of the commodities industry and this could result in large fluctuations in the price of CPER's units.

The price of CPER's units may be influenced by factors such as the short-term supply and demand for copper futures and the short-term supply and demand for CPER's units. This may cause the units to trade at a price that is above or below CPER's NAV per unit. Accordingly, changes in the price of units may substantially vary from the changes in the value of the SummerHaven Copper Index Total Return (SCI). If this variation occurs, then you may not be able to effectively use CPER as a way to indirectly invest in the SCI.

For further discussion of these and additional risks associated with an investment in CPER units, see the prospectus that has preceded or accompanied this announcement, downloaded at http://www.unitedstatescopperindexfund.com/documents/pdfs/cper-prospectus-20120524.pdf.

Not FDIC insured, may lose value, no bank guarantee.

An investment in CPER is not suitable for all investors.  Commodity trading is highly speculative and CPER is not suitable for all investors.  CPER is likely to be volatile and could suffer from periods of prolonged decline in value.

Units are not individually redeemable and the owners of Units may purchase or redeem Units from a Fund in Creation/Redemption Units only.
