The price of a fund's units may be influenced by factors such as the short-term supply and demand for commodity futures and the short-term supply and demand for these units. This may cause the units to trade at a price that is above or below these funds NAV per unit. Accordingly, daily changes in the price of units may substantially vary from the daily changes in the value of the benchmark futures contract. If this variation occurs, then you may not be able to effectively use these funds as a way to indirectly invest in changes in the price of commodities.
For further discussion of these and additional risks associated with an investment in any of these units, see the prospectus that has preceded or accompanied this announcement, downloaded at http://www.unitedstatescommodityfunds.com.
