UNG 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. UNG is speculative and involves a high degree of risk. An investor may lose all or substantially all of an investment in UNG. Funds that focus on a single sector generally experience greater volatility.

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

Investing in UNG subjects you to the risks of the natural gas industry. These risks could result in large fluctuations in the price of UNG'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 natural gas and you may not be able to effectively use UNG as a way to hedge the risk of losses in your natural gas-related transactions or as a way to indirectly invest in natural gas.

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