THE RISKS YOU FACE

You could lose money investing in the Shares. You should consider carefully the risks described below before making an investment decision. You should also refer to the other information included in this Prospectus.

The Shares are designed to reflect as closely as possible the changes, positive or negative, in the level of its Index, over time, through its portfolio of exchange traded futures contracts on its Index Commodities. The value of the Shares relates directly to the value of its portfolio, less the liabilities (including estimated accrued but unpaid expenses) of the Fund. The price of the various Index Commodities may fluctuate widely. Several factors may affect the prices of the Index Commodities, including, but not limited to:

The net asset value per share of the Shares of the Fund will change as fluctuations occur in the market value of its portfolio. Investors should be aware that the public trading price of a Basket of Shares may be different from the net asset value of a Basket of Shares (i.e., 200,000 Shares may trade at a premium over, or a discount to, net asset value of a Basket of Shares) and similarly the public trading price per Share may be different from the net asset value per Share. Consequently, an Authorized Participant may be able to create or redeem a Basket of Shares at a discount or a premium to the public trading price per Share. This price difference may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares are closely related, but not identical to the same forces influencing the prices of the Index Commodities comprising the Index, trading individually or in the aggregate at any point in time. Investors also should note that the size of the Fund in terms of total assets held may change substantially over time and from time-to-time as Baskets are created and redeemed.

Authorized Participants or their clients or customers may have an opportunity to realize a riskless profit if they can purchase a Basket of the Fund at a discount to the public trading price of the Shares or can redeem a Basket at a premium over the public trading price of such Shares. The Managing Owner expects that the exploitation of such arbitrage opportunities by Authorized Participants and their clients and customers will tend to cause the public trading price to track net asset value per Share closely over time.

The value of a Share may be influenced by non-concurrent trading hours between the NYSE Arca and the various futures exchanges on which the Index Commodities are traded. While the Shares trade on the NYSE Arca from 9:30 a.m. to 4:00 p.m. Eastern Standard Time, the trading hours for the futures exchanges on which each of the Index Commodities trade may not necessarily coincide during all of this time. For example, while the Shares of the Fund trade on the NYSE Arca until 4:00 p.m. Eastern Standard Time, liquidity in the global corn market will be reduced after the close of the CBOT at 2:15 p.m. Eastern Standard Time. As a result, during periods when the NYSE Arca is open and the futures

exchanges on which the Index Commodities are traded are closed, trading spreads and the resulting premium or discount on the Shares may widen and, therefore, increase the difference between the price of the Shares and the net asset value of such Shares.

CFTC and commodity exchange rules impose speculative position limits on market participants, including the Fund, trading in certain commodities. These position limits prohibit any person from holding a position of more than a specific number of such futures contracts.

In the aggregate, the Index is composed of 11 Index Commodities, which are all subject to speculative position limits imposed by the CFTC and/or the rules of the futures exchanges on which the futures contracts for the applicable Index Commodities are traded. The purposes of speculative position limits are to diminish, eliminate or prevent sudden or unreasonable fluctuations or unwarranted changes in the prices of futures contracts. Currently, speculative position limits (i) for corn, oats, wheat, soybean, soybean oil and cotton are determined by the CFTC and (ii) for all other commodities are determined by the futures exchanges. Pursuant to the statutory mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, which was signed into law on July 21, 2010, the CFTC adopted final regulations on October 18, 2011, or the Regulations, which, in pertinent part, impose new federal position limits on futures and options on a subset of energy, metal, and agricultural commodities, or the Referenced Contracts, and economically equivalent swaps. The Regulations were to go into effect 60 days after the term “swap” is further defined pursuant to Section 721 of the Dodd-Frank Act. However, on September 28, 2012, a federal court issued an order vacating the Regulations. At this time, it is not certain whether the CFTC will appeal the federal court’s order or propose new position limits rules identical to the Regulations but in conformity with procedural guidelines set forth in the federal court’s order.

Generally, speculative position limits in the physical delivery markets are set at a stricter level during the spot month, the month when the futures contract matures and becomes deliverable, versus the

limits set for all other months. If the Managing Owner determines that the Fund’s trading may be approaching any of these speculative position limits, the Fund may reduce its trading in that commodity or trade in other commodities or instruments that the Index Sponsor determines comply with the rules and goals of the Index. Below is a chart that sets forth certain relevant information, including current speculative position limits for each Affected Index Commodity that any person may hold, separately or in combination, net long or net short, for the purchase or sale of any commodity futures contract or, on a futures-equivalent basis, options thereon. Speculative position limit levels remain subject to change by the CFTC or the relevant exchanges.

Exchanges may also establish accountability levels applicable to futures contracts. An exchange may order a person who holds or controls aggregate positions in excess of specified position accountability levels not to further increase the positions, to comply with any prospective limit which exceeds the size of the position owned or controlled, or to reduce any open position which exceeds position accountability levels if the exchange determines that such action is necessary to maintain an orderly market. Under current regulations, subject to any relevant exemptions, traders, such as the Fund, may not exceed speculative position limits, either individually or in the aggregate with other persons with whom they are under common control or ownership. Under the vacated Regulations, the CFTC would have required certain persons to aggregate exchange listed futures and economically equivalent swap positions owned or controlled by such persons.

[Remainder of page left blank intentionally.]

Because the Fund may be subject to position limits and, consequently, the Fund’s ability to issue new Baskets, or the Fund’s ability to reinvest income in additional futures contracts corresponding to the Affected Index Commodities may be limited to the extent these activities would cause such Fund to exceed its applicable position limits. Limiting the size of the Fund may affect the correlation between the price of the Shares, as traded on the NYSE Arca, and the net asset value of the Shares. That is, the inability to create additional Baskets could result in Shares trading at a premium or discount to net asset value of the Shares.

Under the vacated Regulations, the CFTC, among other things, established speculative position limits on exchange listed futures and options on physical commodities (including certain energy, metals and agricultural products) and economically equivalent over-the-counter derivatives. Under the vacated

Regulations, the CFTC also established aggregate position limits for certain other contracts based on the same underlying commodity, including certain contracts traded on non-U.S. exchanges. Depending on the outcome of any future CFTC or futures exchange rulemaking, as applicable, the rules concerning position limits may be amended in a manner that is detrimental to the Fund. For example, if the amended rules are detrimental to the Fund, its ability to issue new Baskets, or reinvest income in additional futures contracts corresponding to the Affected Index Commodities, may be limited to the extent these activities would cause the Fund to exceed the applicable position limits. Limiting the size of the Fund may affect the correlation between the price of the Shares of the Fund, as traded on the NYSE Arca, and the net asset value of the Shares. That is, the inability to create additional Baskets could result in Shares in the Fund trading at a premium or discount to net asset value of the Shares.

It is possible that the Fund’s performance may not fully replicate the changes in the level of the Index due to disruptions in the markets for the relevant Index Commodities, the imposition of speculative position limits (as discussed in “The Risks You Face — (3) Regulatory and Exchange Position Limits and Other Rules May Restrict the Creation of Baskets and the Operation of the Fund”), or due to other extraordinary circumstances. As the Fund approaches or reaches position limits with respect to certain futures contracts comprising its Index, the Fund may commence investing in other futures contracts based on commodities that comprise the Index and in futures contracts based on commodities other than commodities that comprise the Index that, in the commercially reasonable judgment of the Managing Owner, tend to exhibit trading prices that correlate with a futures contract that comprises the Index. In addition, the Fund is not able to replicate exactly the changes in the level of the Index because the total return generated by the Fund is reduced by expenses and transaction costs, including those incurred in connection with the Fund’s trading activities, and increased by interest income from the Fund’s holdings of short-term high credit quality fixed income securities. Tracking the Index requires trading of the Fund’s portfolio with a view to tracking the Index over time and is dependent upon the skills of the Managing Owner and its trading principals, among other factors.

The Fund is not actively managed by traditional methods. Therefore, if positions in any one or more of its Index Commodities are declining in value, the Fund will not close out such positions, except in connection with a change in the composition or weighting of the Index. The Managing Owner will seek to cause the net asset value of the Fund to track its Index during periods in which the Index is flat or declining as well as when the Index is rising.

Trading in Shares of the Fund may be halted due to market conditions or, in light of NYSE Arca rules and procedures, for reasons that, in the view of the NYSE Arca, make trading in the Shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules that require trading to be halted for a specified period based on a specified market decline. There can be no assurance that the requirements necessary to maintain the listing of the Shares will continue to be met or will remain unchanged. The Fund will be terminated if its Shares are delisted.

Although the Shares are listed and traded on the NYSE Arca, there can be no guarantee that an active trading market for the Shares will be maintained. If you need to sell your Shares at a time when no active market for them exists, the price you receive for your Shares, assuming that you are able to sell them, likely will be lower than that you would receive if an active market did exist.

The mechanisms and procedures governing the creation, redemption and offering of the Shares have been developed specifically for these securities products. Consequently, there may be unanticipated problems or issues with respect to the mechanics of the operations of the Fund and the trading of the Shares that could have a material adverse effect on an investment in the Shares. In addition, although the Fund is not actively “managed” by traditional methods, to the extent that unanticipated operational or trading problems or issues arise, the Managing Owner’s past experience and qualifications may not be suitable for solving these problems or issues.

The Managing Owner was formed to be the managing owner of investment vehicles such as the Fund and has been managing such investment vehicles since January 2006. The past performances of the Managing Owner’s management of other commodity pools are no indication of its ability to manage investment vehicles such as the Fund. If the experience of the Managing Owner and its principals is not adequate or suitable to manage investment vehicles such as the Fund, the operations of the Fund may be adversely affected.

Although past performance is not necessarily indicative of future results, the Fund’s performance history might (or might not) provide you with more information on which to evaluate an investment in the Fund. Likewise, the Index has a history which might be indicative of the future Index results, or of the future performance of the Fund. Therefore, you will have to make your decision to invest in the Fund without relying on the Fund’s past performance history or the Index’s closing level history.

The Index is concentrated in terms of the number of commodities represented. The Fund is concentrated in approximately 11 commodities. You should be aware that other commodities indexes are more diversified in terms of both the number and variety of commodities included. Concentration in fewer commodities may result in a greater degree of volatility in the Index and the net asset value of the Fund which tracks the Index under specific market conditions and over time.

Futures contracts have a high degree of price variability and are subject to occasional rapid and substantial changes. Consequently, you could lose all or substantially all of your investment in the Fund.

Although past Index levels are not necessarily indicative of future Index levels, the peak-to-valley drawdown periods that the Index has experienced has been unusually long and has lasted for multi-year drawdown periods. Please see the chart on page 40 for information regarding worst peak-to-valley drawdown periods with respect to the Index.

Because it is expected that the Fund’s performance will track the change of its underlying Index, the Fund would suffer a continuous drawdown during the period that an Index suffers such a drawdown period, and in turn, the value of your Shares will also suffer.

The Fund directly is subject to the fees and expenses described herein which are payable irrespective of profitability. See “Breakeven Table” on page 14 Consequently, depending upon the performance of the Fund and the interest rate environment, the expenses of the Fund could, over time, result in losses to your investment in the Fund. You may never achieve profits, significant or otherwise by investing in the Fund.

You cannot be assured that the Managing Owner will be willing or able to continue to service the Fund for any length of time. If the Managing Owner discontinues its activities on behalf of the Fund, the Fund may be adversely affected.

Futures positions cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption, such as when foreign governments may take or be subject to political actions which disrupt

the markets in their currency or major exports, can also make it difficult to liquidate a position.

There can be no assurance that market illiquidity will not cause losses for the Fund. The large size of the positions which the Fund may acquire increases the risk of illiquidity by both making its positions more difficult to liquidate and increasing the losses incurred while trying to do so.

The Fund may, in its discretion, suspend the right of redemption or postpone the redemption settlement date, (1) for any period during which an emergency exists as a result of which the redemption distribution is not reasonably practicable, or (2) for such other period as the Managing Owner determines to be necessary for the protection of the Shareholders of the Fund. In addition, the Fund will reject a redemption order if the order is not in proper form as described in the Participant Agreement or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. Any such postponement, suspension or rejection could adversely affect a redeeming Authorized Participant. For example, the resulting delay may adversely affect the value of the Authorized Participant’s redemption proceeds if the net asset value of the Fund declines during the period of delay. The Fund disclaims any liability for any loss or damage that may result from any such suspension or postponement.

Futures trading is a risk transfer economic activity. For every gain there is an equal and offsetting loss rather than an opportunity to participate over time in general economic growth. Unlike most alternative investments, an investment in the Shares does not involve acquiring any asset with intrinsic value. Overall stock and bond prices could rise significantly and the economy as a whole prosper while the Shares trade unprofitably.

Historically, commodity futures’ returns have tended to exhibit low to negative correlation with the returns of other assets such as stocks and bonds. Although commodity futures trading can provide a diversification benefit to investor portfolios because of its low to negative correlation with other financial assets, the fact that the Index is not 100% negatively correlated with financial assets such as stocks and bonds means that the Fund cannot be expected to be automatically profitable during unfavorable periods for the stock or bond market, or vice-versa. If the Shares perform in a manner that correlates with the general financial markets or do not perform successfully, you will obtain no diversification benefits by investing in the Shares and the Shares may produce no gains to offset your losses from other investments.

The Fund is not registered as an investment company under the Investment Company Act of 1940, and is not required to register under such Act. Consequently, Shareholders will not have the regulatory protections provided to investors in registered and regulated investment companies.

A portion of the Fund’s trading is expected to be conducted on commodity exchanges outside the United States. Trading on such exchanges is not regulated by any United States governmental agency and may involve certain risks not applicable to trading on United States exchanges, including different or diminished investor protections. In trading contracts denominated in currencies other than U.S. dollars, Shares are subject to the risk of adverse exchange-rate movements between the dollar and the functional currencies of such contracts. Investors could incur substantial losses from trading on foreign exchanges which such investors would not have otherwise been subject had the Fund’s trading been limited to U.S. markets.

The Fund is subject to actual and potential conflicts of interest involving the Managing Owner, various commodity futures brokers and Authorized Participants. The Managing Owner and its principals, all of whom are engaged in other investment activities, are not required to devote substantially all of their time to the business of the Fund, which also presents the potential for numerous conflicts of interest with the Fund. As a result of these and other relationships, parties involved with the Fund have a financial incentive to act in a manner other than in the best interests of the Fund and the Shareholders. The Managing Owner has not established any formal procedure to resolve conflicts of interest. Consequently, investors are dependent on the good faith of the respective parties subject to such conflicts to resolve them equitably. Although the Managing Owner attempts to monitor these conflicts, it is extremely difficult, if not impossible, for the Managing Owner to ensure that these conflicts do not, in fact, result in adverse consequences to the Shareholders.

The Fund may be subject to certain conflicts with respect to the Commodity Broker, including, but not limited to, conflicts that result from receiving greater amounts of compensation from other clients, or purchasing opposite or competing positions on behalf of third party accounts traded through the Commodity Broker.

Shareholders will be subject to U.S. federal income taxation and, in some cases, state, local, or foreign income taxation on their allocable share of the Fund’s taxable income, whether or not they receive cash distributions from the Fund. Shareholders may not receive cash distributions equal to their share of the Fund’s taxable income or even the tax liability that results from such income.

U.S. federal income tax rules applicable to partnerships are complex and often difficult to apply to publicly traded partnerships. The Fund will apply certain assumptions and conventions in an attempt to comply with applicable rules and to report items of income, gain, loss and deduction to the Shareholders in a manner that reflects the Shareholders’ beneficial interest in such tax items, but these assumptions and conventions may not be in compliance with all aspects of the applicable tax requirements. It is possible that the IRS will successfully assert that the conventions and assumptions used by the Fund do not satisfy the technical requirements of the Code and/or Treasury Regulations and could require that items of income, gain, loss and deduction be adjusted or reallocated in a manner that adversely affects one or more Shareholders.

Under current law, long-term capital gains are taxed to non-corporate investors at reduced U.S. federal income tax rates. This tax treatment may be adversely affected, changed or repealed by future changes in, or the expiration of, tax laws at any time.

PROSPECTIVE INVESTORS ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISERS AND COUNSEL WITH RESPECT TO THE POSSIBLE TAX CONSEQUENCES TO THEM OF AN INVESTMENT IN THE SHARES; SUCH TAX CONSEQUENCES MAY DIFFER WITH RESPECT TO DIFFERENT INVESTORS.

The Commodity Exchange Act requires a clearing broker to segregate all funds received from customers from such broker’s proprietary assets. If the Commodity Broker fails to do so, the assets of the Fund might not be fully protected in the event of the Commodity Broker’s bankruptcy. Furthermore, in the event of the Commodity Broker’s bankruptcy, the Shares could be limited to recovering either a pro rata share of all available funds segregated on behalf of the Commodity Broker’s combined customer accounts or the Shares may not recover any assets at all, even though certain property specifically traceable to the Fund was held by the Commodity Broker. The Commodity Broker may, from time-to-time, have been the subject of certain regulatory and private causes of action. Such material actions, if any, are described under “The Commodity Broker.”

In the event of a bankruptcy or insolvency of any exchange or a clearing house, the Fund could experience a loss of the funds deposited through its Commodity Broker as margin with the exchange or clearing house, a loss of any unrealized profits on its open positions on the exchange, and the loss of profits on its closed positions on the exchange.

The global financial markets have in the past few years gone through pervasive and fundamental disruptions that have led to extensive and unprecedented governmental intervention. Such intervention has in certain cases been implemented on an “emergency” basis, suddenly and substantially eliminating market participants’ ability to continue to implement certain strategies or manage the risk of their outstanding positions. In addition — as one would expect given the complexities of the financial markets and the limited time frame within which governments have felt compelled to take action — these interventions have typically been unclear in

scope and application, resulting in confusion and uncertainty which in itself has been materially detrimental to the efficient functioning of the markets as well as previously successful investment strategies.

The Fund may incur major losses in the event of disrupted markets and other extraordinary events in which historical pricing relationships become materially distorted. The risk of loss from pricing distortions is compounded by the fact that in disrupted markets many positions become illiquid, making it difficult or impossible to close out positions against which the markets are moving. The financing available to market participants from their banks, dealers and other counterparties is typically reduced in disrupted markets. Such a reduction may result in substantial losses to the affected market participants. Market disruptions may from time-to-time cause dramatic losses, and such events can result in otherwise historically low-risk strategies performing with unprecedented volatility and risk.

The regulation of commodity interest transactions in the United States is a rapidly changing area of law and is subject to ongoing modification by governmental and judicial action. Considerable regulatory attention has been focused on non-traditional investment pools that are publicly distributed in the United States. The Dodd-Frank Act seeks to regulate markets, market participants and financial instruments that previously have been unregulated and substantially alters the regulation of many other markets, market participants and financial instruments. Because many provisions of the Dodd-Frank Act require rulemaking by the applicable regulators before becoming fully effective and the Dodd-Frank Act mandates multiple agency reports and studies (which could result in additional legislative or regulatory action), it is difficult to predict the impact of the Dodd-Frank Act on the Fund, the Managing Owner, and the markets in which the Fund may invest, the Net Asset Value of the Fund or the market price of the Shares. The Dodd-Frank Act could result in the Fund’s investment strategy becoming non-viable or non-economic to implement. Therefore, the Dodd-Frank Act and regulations adopted pursuant to the Dodd-Frank Act could have a material adverse impact on the profit potential of the Fund and in turn the value of your Shares.

The Managing Owner has consulted with counsel, accountants and other advisers regarding the formation and operation of the Fund. No counsel has been appointed to represent you in connection with the offering of the Shares. Accordingly, you should consult your own legal, tax and financial advisers regarding the desirability of an investment in the Shares.

The Managing Owner may withdraw from the Trust upon 120 days’ notice, which would cause the Fund to terminate unless a substitute managing owner were obtained. Owners of 50% of the Shares of the Fund have the power to terminate the Fund. If it is so exercised, investors who may wish to continue to invest in the Fund’s Index through a fund vehicle will have to find another vehicle, and may not be able to find another vehicle that offers the same features as the Fund. See “Description of the Shares; The Fund; Certain Material Terms of the Trust Declaration — Termination Events” for a summary of termination events. Such detrimental developments could cause you to liquidate your investments and upset the overall maturity and timing of your investment portfolio. If the registrations with the CFTC or memberships in the NFA of the Managing Owner or the Commodity Broker were revoked or suspended, such entity would no longer be able to provide services to the Fund.

As interests in separate series of a Delaware statutory trust, the Shares have none of the statutory rights normally associated with the ownership of shares of a corporation (including, for example, the right to bring “oppression” or “derivative” actions). In addition, the Shares have limited voting and distribution rights (for example, Shareholders do not have the right to elect directors and the Fund is not required to pay regular distributions, although the Fund may pay distributions in the discretion of the Managing Owner).

The Fund constitutes a relatively new type of investment vehicle. The Fund competes with other financial vehicles, including other commodity pools, hedge funds, traditional debt and equity securities issued by companies in the commodities industry, other securities backed by or linked to such commodities, and direct investments in the underlying commodities or commodity futures contracts. Market and financial conditions, and other conditions beyond the Managing Owner’s control, may make it more attractive to invest in other financial vehicles or to invest in such commodities directly, which could limit the market for the Shares and therefore reduce the liquidity of the Shares.

While the Managing Owner believes that all intellectual property rights needed to operate the Fund are either owned by or licensed to the Managing Owner or have been obtained, third parties may allege or assert ownership of intellectual property rights which may be related to the design, structure and operations of the Fund. To the extent any claims of such ownership are brought or any proceedings are instituted to assert such claims, the negotiation, litigation or settlement of such claims, or the ultimate disposition of such claims in a court of law if a suit is brought, may adversely affect the Fund and an investment in the Shares, for example, resulting in expenses or damages or the termination of the Fund.

Under the Trust Declaration, the Trustee and the Managing Owner have the right to be indemnified for any liability or expense either incurs without negligence or misconduct. That means the Managing Owner may require the assets of the Fund to be sold in order to cover losses or liability suffered by it or by the Trustee. Any sale of that kind would reduce the net asset value of the Fund and, consequently, the value of the Shares.

Calculating the net asset value of the Fund includes, in part, any unrealized profits or losses on open commodity futures contracts. Under normal circumstances, the net asset value of the Fund reflects the settlement price of open commodity futures contracts on the date when the net asset value is being calculated. However, if a commodity futures contract traded on an exchange (both U.S. and, to the extent it becomes applicable, non-U.S. exchanges) could not be liquidated on such day (due to the operation of daily limits or other rules of the exchange upon which that position is traded or otherwise), the Managing Owner may value such futures contract pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. In such a situation, there is a risk that the calculation of the net asset value of the Fund on such day will not accurately reflect the realizable market value of such commodity futures contract. For example, daily limits are generally triggered in the event of a significant change in market price of a commodity futures contract. Therefore, as a result of the daily limit, the current settlement price is unavailable. Because the Managing Owner may value such futures contract pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards, there is a risk that the resulting calculation of the net asset value of the Fund could be under or overstated, perhaps to a significant degree.

The Shares are limited liability investments; investors may not lose more than the amount that they invest plus any profits recognized on their investment. However, Shareholders could be required, as a matter of bankruptcy law, to return to the estate of the Fund any distribution they received at a time when the Fund was in fact insolvent or in violation of its Trust Declaration. In addition, although the Managing Owner is not aware of this provision ever having been invoked in the case of any public futures fund, Shareholders agree in the

Trust Declaration that they will indemnify the Fund for any harm suffered by it as a result of

This Fund is a series or a part of a Delaware statutory trust. Pursuant to Delaware law, the organization of the Trust provides that the assets and liabilities of this Fund is separate from the assets and liabilities of all other series of the Trust (e.g., the Sectors Funds), as well as the larger Trust itself. Though such organization may, under state law, protect the assets of the Fund in an insolvency action brought by the creditors of one or more of the Sectors Funds, or series of the Trust, this may be insufficient to protect the assets of the Fund from such creditors in an insolvency action in Federal court, or in a court in a foreign jurisdiction. Accordingly, an insolvency resulting from one or more of the Sectors Funds in the Trust or the Trust itself may have a material adverse effect on the Fund. The material risks associated with the Sectors Funds have not been included in this disclosure document.

INVESTMENT OBJECTIVE

The Fund seeks to track changes, whether positive or negative, in the level of the DBIQ Diversified Agriculture Index Excess Return™, or the Index, over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury and other high credit quality short-term fixed income securities over its expenses. The Shares are designed for investors who want a cost-effective and convenient way to invest in commodity futures on U.S. and non-U.S. markets.

Advantages of investing in the Shares include:

Investing in the Shares does not insulate Shareholders from certain risks, including price volatility.

The Fund pursues its investment objective by investing in a portfolio of exchange-traded futures on the commodities comprising the Index.

The Index, which is comprised of one or more underlying commodities, or Index Commodities, is intended to reflect the agricultural sector. The Index Commodities consist of Corn, Soybeans, Wheat, Kansas City Wheat, Sugar, Cocoa, Coffee, Cotton, Live Cattle, Feeder Cattle and Lean Hogs.

If the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to any Index Commodity by investing in a specific futures contract that comprises the Index, the Fund may invest in a futures contract referencing the particular Index Commodity other than the specific contract that comprises the Index or, in the alternative, invest in other futures contracts not based on the particular Index Commodity if, in the commercially reasonable judgment of the Managing Owner, such futures contracts tend to exhibit trading prices that correlate with a futures contract that comprises the Index.

The Fund will make distributions at the discretion of the Managing Owner. To the extent that the Fund’s actual and projected interest income from its holdings of United States Treasury securities and other high credit quality short-term fixed income securities exceeds the actual and projected fees and expenses of the Fund, the Managing Owner expects periodically to make distributions of the amount of such excess. The Fund currently does not expect to make distributions with respect to capital gains. Depending on the Fund’s performance for the taxable year and your own tax situation for such year, your income tax liability for the taxable year for your allocable share of the Fund’s net ordinary income or loss and capital gain or loss may exceed any distributions you receive with respect to such year.

The sponsor of the Index, or the Index Sponsor, is Deutsche Bank AG London. Trade Mark applications in the United States are pending with respect to both the Trust and aspects of the Index. Deutsche Bank AG is an affiliate of the Fund and the Managing Owner.

Under the Trust Declaration, Wilmington Trust Company, the Trustee of the Fund, has delegated to the Managing Owner the exclusive management and control of all aspects of the business of the Fund. The Trustee will have no duty or liability to supervise or monitor the performance of the Managing Owner, nor will the Trustee have any liability for the acts or omissions of the Managing Owner.

The Shares are intended to provide investment results that generally correspond to the changes, positive or negative, in the levels of the Fund’s Index over time.

The value of the Shares is expected to fluctuate in relation to changes in the value of its portfolio. The market price of the Shares may not be identical to the net asset value per Share, but these two valuations are expected to be very close. See “The Risks You Face — (2) Net Asset Value May Not Always Correspond to Market Price and, as a Result, Baskets may be Created or Redeemed at a Value that Differs from the Market Price of the Shares.”

The Index Sponsor publishes the closing level of the Index daily. The Managing Owner publishes the net asset value of the Fund and the net asset value per Share daily. Additionally, the Index Sponsor publishes the intra-day Index level, and the Managing Owner publishes the indicative value per Share of the

Fund (quoted in U.S. dollars) once every fifteen seconds throughout each trading day.

All of the foregoing information is published as follows:

The intra-day level of the Index (symbol: DBAGIX) and the intra-day indicative value per Share (symbol: DBA.IV) (each quoted in U.S. dollars) are published once every fifteen seconds throughout each trading day on the consolidated tape, Reuters and/or Bloomberg and on the Managing Owner’s website at http://www.dbfunds.db.com , or any successor thereto.

The current trading price per Share (symbol: DBA) (quoted in U.S. dollars) is published continuously as trades occur throughout each trading day on the consolidated tape, Reuters and/or Bloomberg and on the Managing Owner’s website at http://www.dbfunds.db.com , or any successor thereto.

The most recent end-of-day Index closing level (symbol: DBLCDBAE) is published as of the close of business for the NYSE Arca each trading day on the consolidated tape, Reuters and/or Bloomberg and on the Managing Owner’s website at http://www.dbfunds.db.com , or any successor thereto.

The most recent end-of-day net asset value of the Fund (symbol: DBA.NV) is published as of the close of business on Reuters and/or Bloomberg and on the Managing Owner’s website at http://www.dbfunds.db.com, or any successor thereto. In addition, the most recent end-of-day net asset value of the Fund (symbol: DBA.NV) is published the following morning on the consolidated tape.

All of the foregoing information with respect to the Index, including the Index’s history, is also published at https://index.db.com .

The Index Sponsor obtains information for inclusion in, or for use in the calculation of, the Index from sources the Index Sponsor considers reliable. None of the Index Sponsor, the Managing Owner, the Fund or any of their respective affiliates accepts responsibility for or guarantees the accuracy and/or completeness of the Index or any data included in the Index.

The intra-day indicative value per Share is based on the prior day’s final net asset value, adjusted four times per minute throughout the day to reflect the continuous price changes of the Fund’s futures positions. The final net asset value of the Fund and the final net asset value per Share is calculated as of the closing time of the NYSE Arca or the last to close of the exchanges on which the Fund’s futures contracts are traded, whichever is later, and posted in the same manner. Although a time gap may exist between the close of the NYSE Arca and the close of the exchanges on which the Fund’s futures contracts are traded, there is no effect on the net asset value calculations as a result.

There can be no assurance that the Fund will achieve its investment objective or avoid substantial losses.

Role of Managing Owner

The Managing Owner serves as the commodity pool operator and commodity trading advisor of the Fund.

Specifically, the Managing Owner:

The Managing Owner is registered as a commodity pool operator and commodity trading advisor with the CFTC and is a member of the NFA.

The principal office of the Managing Owner is located at 60 Wall Street, New York, New York 10005. The telephone number of the Managing Owner is (212) 250-5883.

Market Diversification

As global markets and investing become more complex, the inclusion of futures may continue to increase in traditional portfolios of stocks and bonds managed by advisors seeking improved balance and diversification. The globalization of the world’s economy has the potential to offer significant investment opportunities, as major political and economic events continue to have an influence, in some cases a dramatic influence, on the world’s markets, creating risk but also providing the potential for profitable trading opportunities. By allocating a portion of the risk segment of their portfolios to the Fund and investing in futures comprising its Index, investors have the potential, if their investments are successful, to reduce the volatility of their portfolios over time and the dependence of such portfolios on any single nation’s economy.
