United States Oil Fund

The United States Oil Fund, LP ("USO") is a domestic exchange traded security designed to track the movements of light, sweet crude oil ("West Texas Intermediate"). USO issues units that may be purchased and sold on the NYSE Arca.

The investment objective of USO is for the changes in percentage terms of its units' net asset value ("NAV") to reflect the changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the changes in the price of the futures contract for light, sweet crude oil traded on the New York Mercantile Exchange (the "NYMEX"), less USO's expenses.

USO is not a mutual fund or any other type of Investment Company within the meaning of the Investment Company Act of 1940, as amended, and is not subject to regulation thereunder.

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

For further discussion of these and additional risks associated with an investment in USO units, click here.

Investing in USO subjects you to the risks of the oil industry. These risks could result in large fluctuations in the price of USO's units. An investor could lose all or substantially all of his/her investment.

The price of units may not accurately track the spot price of oil and you may not be able to effectively use USO as a way to hedge the risk of losses in your oil-related transactions or as a way to indirectly invest in oil.

Investors buy and sell units in the secondary market (i.e., not directly from USO). Only "authorized purchasers" may trade directly with USO, in minimum blocks of 100,000 units.
