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

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

The Fund could terminate at any time and cause the liquidation of your investment which may upset the overall maturity and timing of your investment portfolio. An unanticipated number of redemption requests during a short period of time could have an adverse effect on the NAV of the Fund.

The Fund may not earn trading gains sufficient to compensate for the fees and expenses that it must pay, and as such, the Fund may not earn any profit. You should not invest in DNO if you will need cash distributions from DNO to pay taxes on your share of income and gains of DNO, if any, or for any other reason.

DNO seeks to track the inverse of the total return movement of the Benchmark Futures Contract on a daily basis.

Investing in DNO subjects you to the risks of the oil industry. These risks could result in large fluctuations in the price of DNO'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 DNO 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 DNO). Only "authorized purchasers" may trade directly with DNO, in minimum blocks of 100,000 units.
