This Prospectus is dated December 10, 2015.

The Trust and the Fund

PowerShares DB Multi-Sector Commodity Trust, or the Trust, was formed as a Delaware statutory trust, in seven separate series, or funds, on August 3, 2006. PowerShares DB Agriculture Fund, or the Fund, is a series of the Trust. The Fund issues common units of beneficial interest, or Shares, which represent units of fractional undivided beneficial interest in and ownership of the Fund. The term of the Trust and the Fund is perpetual (unless terminated earlier in certain circumstances). The principal offices of the Trust and the Fund are located at c/o Invesco PowerShares Capital Management LLC, 3500 Lacey Road, Suite 700, Downers Grove, IL 60515, and its telephone number is (800) 983-0903.

The Trust was organized in separate series as a Delaware statutory trust rather than as separate statutory trusts in order to achieve certain administrative efficiencies. The interests of investors are not adversely affected by the choice of form of organization. As of the date of this Prospectus, the Trust consists of the following seven series — PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund, PowerShares DB Gold Fund, PowerShares DB Silver Fund, PowerShares DB Base Metals Fund and PowerShares DB Agriculture Fund. This Prospectus is for the Fund only and not for the first 6 funds listed in the prior sentence, or the Sectors Funds. The Sectors Funds, which are series of the Trust, are not being offered by this Prospectus. Information regarding

both the Fund and the Sectors Funds (and any other additional series of the Trust, as applicable) is available at www.invescopowershares.com.

Shares Listed on the NYSE Arca

The Shares of the Fund are listed on the NYSE Arca under the symbol “DBA.”

Secondary market purchases and sales of Shares will be subject to ordinary brokerage commissions and charges.

Purchases and Sales in the Secondary Market on the NYSE Arca

The Shares trade on the NYSE Arca like any other equity security.

Baskets of Shares may be created or redeemed only by Authorized Participants. It is expected that Baskets will be created when the market price per Share is at a premium to the net asset value per Share. Authorized Participants are expected to sell such Shares, which are listed on the NYSE Arca, to the public at prices that are expected to reflect, among other factors, the trading price of the Shares on the NYSE Arca and the supply of and demand for Shares at the time of sale and are expected to fall between net asset value and the trading price of the Shares on the NYSE Arca at the time of sale. Similarly, it is expected that Baskets will be redeemed when the market price per Share is at a discount to the net asset value per Share. Retail investors seeking to purchase or sell Shares on any day are expected to effect such transactions in the secondary market, on the NYSE Arca, at the market price per Share, rather than in connection with the creation or redemption of Baskets.

The market price of the Shares may not be identical to the net asset value per Share, but these valuations are expected to be very close. Investors are able to use the indicative intra-day value per Share to determine if they want to purchase in the secondary market via the NYSE Arca. 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 trading day to reflect the continuous price changes of the Fund’s futures positions, which provide a continuously updated estimated net asset value per Share.

Retail investors may purchase and sell Shares through traditional brokerage accounts. Purchases or sales of Shares may be subject to customary brokerage commissions. Investors are encouraged to review the terms of their brokerage accounts for applicable charges.

CUSIP Number

The CUSIP number of the Fund is 73936B408.

Risk Factors

An investment in Shares is speculative and involves a high degree of risk. The summary risk factors set forth below are intended merely to highlight certain risks of the Fund. The Fund has particular risks that are set forth elsewhere in this Prospectus.

The Trustee

Wilmington Trust Company, or the Trustee, a Delaware trust company, is the sole trustee of the Trust. The Trustee delegated to the Managing Owner all of the power and authority to manage the business and affairs of the Trust and the Fund and has only nominal duties and liabilities to the Trust and the Fund.

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 Index Sponsor calculates the Index on both an excess return basis and a total return basis. The excess return basis calculation reflects the change in market value over time, whether positive or negative, of the applicable underlying commodity futures only. The total return basis calculation reflects the sum of the change in market value over time, whether positive or negative, of the applicable underlying commodity futures plus the return on 3-month U.S. Treasury bills. The Fund seeks to track changes, whether positive or negative, in the level of the Index over time, plus the excess, if any, of its interest income from its holdings of United States Treasury and other high credit quality short-term fixed income securities over its expenses.

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 Fund’s portfolio also will include United States Treasury securities and other high credit quality short-term fixed income securities for deposit with the Fund’s Commodity Broker as margin.

General

Each of the DBIQ Optimum Yield Index Excess Return™, or DBIQ-OYER™, and the DBIQ Index Excess Return™, or DBIQ ER™ (“DBIQ-OYER™” and “DBIQ ER™,” collectively, “DBIQ™” or “DBIQ ER™”), is intended to reflect the changes in market value, positive or negative, in certain sectors of commodities, or an index. The Index is calculated on an excess return, or unfunded basis. The Index is rolled on both an Optimum Yield^TM and non-Optimum Yield^TM basis. The Optimum Yield^TM rolling methodology is aimed at potentially maximizing the roll benefits in backwardated markets and minimizing the losses from rolling in contangoed markets. The non-Optimum Yield^TM portion of the Index is rolled to the next to expire futures contract as provided below under “Contract Selection (Non-OY Single Commodity Indexes only).” The Index is comprised of one or more underlying commodities, or Index Commodities. Each Index Commodity is assigned a weight, or Index Base Weight, which is intended to reflect the proportion of such Index Commodity relative to the Index.

The Index has been calculated back to a base date, or Base Date. On the Base Date of January 18, 1989, the closing level of the Index, or Closing Level, was 100.

The sponsor of the Index is Deutsche Bank Securities Inc., or Index Sponsor.

Composition of the Index

The Index is composed of notional amounts of each of the underlying Index Commodities. The notional amount of each Index Commodity included in the Index is intended to reflect the changes in market value of each such Index Commodity within the Index. The Closing Level of the Index is calculated on each business day by the Index Sponsor based on the closing price of the futures contracts for each of the underlying Index Commodities and the notional amounts of such Index Commodities.

The Index is rebalanced annually in November to ensure that each of the Index Commodities is weighted in the same proportion that such Index Commodities were weighted on the Base Date.

The composition of the Index may be adjusted in the event that the Index Sponsor is not able to calculate the closing prices of the Index Commodities.

The Index includes provisions for the replacement of futures contracts as they approach maturity. This replacement takes place over a period of time in order to lessen the impact on the market for the futures contracts being replaced. With respect to each Index Commodity, the Fund employs a rule-based approach when it ‘rolls’ from one futures contract to another. The Index is comprised of OY Single Commodity Indexes and non-OY Single Commodity Indexes. The Index Commodities that underlie the OY Single Commodity Indexes are Corn, Soybeans, Wheat, Kansas City Wheat and Sugar. The Index Commodities that underlie the non-OY Single Commodity Indexes are Cocoa, Coffee, Cotton, Live Cattle, Feeder Cattle and Lean Hogs. The OY Single Commodity Indexes are rolled to the futures contract which generates the best possible “implied roll yield.” The futures contract with a delivery month within the next thirteen months which generates the best possible implied roll yield will be included in each OY Single Commodity Index. As a result, each OY Single Commodity Index is able to potentially maximize the roll benefits in backwardated markets and minimize the losses from rolling in contangoed markets.

Each of the non-OY Single Commodity Indexes rolls only to the next to expire futures contract as provided below under “Contract Selection (Non-OY Single Commodity Indexes only).”

In general, as a futures contract approaches its expiration date, its price will move towards the spot

price in a contangoed market. Assuming the spot price does not change, this would result in the futures contract price decreasing and a negative implied roll yield. The opposite is true in a backwardated market. Rolling in a contangoed market will tend to cause a drag on an Index Commodity’s contribution to the Fund’s return while rolling in a backwardated market will tend to cause a push on an Index Commodity’s contribution to the Fund’s return.

The futures contract price for each Index Commodity will be the exchange closing price for such Index Commodity on each weekday when banks in New York, New York are open, or Index Business Days. If a weekday is not an Exchange Business Day (as defined in the following sentence) but is an Index Business Day, the exchange closing price from the previous Index Business Day will be used for each Index Commodity. “Exchange Business Day” means, in respect of an Index Commodity, a day that is a trading day for such Index Commodity on the relevant exchange (unless either an Index disruption event or force majeure event has occurred).

Contract Selection (OY Single Commodity Indexes only)

On the first New York business day, or Verification Date, of each month, each Index Commodity futures contract will be tested in order to determine whether to continue including it in the applicable OY Single Commodity Index. If the Index Commodity futures contract requires delivery of the underlying commodity in the next month, known as the Delivery Month, a new Index Commodity futures contract will be selected for inclusion in such OY Single Commodity Index. For example, if the first New York business day is May 1, 2016, and the Delivery Month of the Index Commodity futures contract currently in such OY Single Commodity Index is June 2016, a new Index Commodity futures contract with a later Delivery Month will be selected.

For each underlying Index Commodity of an OY Single Commodity Index, the new Index Commodity futures contract selected will be the Index Commodity futures contract with the best possible “implied roll yield” based on the closing price for each eligible Index Commodity futures contract. Eligible Index Commodity futures contracts are any Index Commodity futures contracts having a Delivery Month (i) no sooner than the month after the Delivery Month of the Index Commodity futures contract currently in such OY Single

Commodity Index, and (ii) no later than the 13^th month after the Verification Date. For example, if the first New York business day is May 1, 2016 and the Delivery Month of an Index Commodity futures contract currently in an OY Single Commodity Index is therefore June 2016, the Delivery Month of an eligible new Index Commodity futures contract must be between July 2016 and June 2017. The implied roll yield is then calculated and the futures contract on the Index Commodity with the best possible implied roll yield is then selected. If two futures contracts have the same implied roll yield, the futures contract with the minimum number of months prior to the Delivery Month is selected.

After selection of the replacement futures contract, each OY Single Commodity Index will roll such replacement futures contract as provided in the sub-paragraph “Monthly Index Roll Period with respect to both OY Single Commodity Indexes and Non-OY Single Commodity Indexes.”

[Remainder of page left blank intentionally.]

After selection of the replacement futures contract, each non-OY Single Commodity Index will roll such replacement futures contract as provided in the sub-paragraph “Monthly Index Roll Period with respect to both OY Single Commodity Indexes and Non-OY Single Commodity Indexes.”

Monthly Index Roll Period with respect to both OY Single Commodity Indexes and Non-OY Single Commodity Indexes

After the futures contract selection with respect to both OY Single Commodity Indexes and non-OY Single Commodity Indexes, the monthly roll for each Index Commodity subject to a roll in that particular month unwinds the old futures contract and enters a position in the new futures contract. This takes place between the 2^nd and 6^th Index Business Day of the month.

On each day during the roll period, new notional holdings are calculated. The calculations for the old Index Commodities that are leaving the Index and the new Index Commodities are then calculated.

On all days that are not monthly index roll days, the notional holdings of each Index Commodity future remains constant.

The Index is re-weighted on an annual basis on the 6^th Index Business Day of each November.

The calculation of the Index is expressed as the weighted average return of the Index Commodities.

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

Shares Should Track Closely the Value of its Index

The Shares are intended to provide investment results that generally correspond to changes, positive or negative, in the levels of the 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.

The Fund holds a portfolio of long futures contracts on the Index Commodities which comprise its Index, each of which are traded on various commodity futures markets in the United States and abroad. The Fund also holds cash and United States Treasury securities and other high credit quality short-term fixed income securities for deposit with its Commodity Broker as margin. The Fund’s portfolio is traded with a view to tracking the changes in its Index over time, whether the Index is rising, falling or flat over any particular period. The Fund is not “managed” by traditional methods, which typically involve effecting changes in the composition of a portfolio on the basis of judgments relating to economic, financial and market considerations with a view to obtaining positive results.

The Managing Owner

Invesco PowerShares Capital Management LLC, a Delaware limited liability company, serves as Managing Owner of the Trust and the Fund. The Managing Owner was formed on February 7, 2003. The Managing Owner is an affiliate of Invesco Ltd. The Managing Owner was formed to be the managing owner of investment vehicles such as exchange-traded funds and has been managing non-commodity futures based exchange-traded funds since 2003 and a commodity futures based exchange-traded fund since 2014. The Managing Owner serves as the commodity pool operator and commodity trading advisor of the Trust and the Fund. The Managing Owner is registered as a commodity pool operator, commodity trading advisor and swap firm with the Commodity Futures Trading Commission, or the CFTC, and is a member of the National Futures Association, or the NFA. As a registered commodity pool operator and commodity trading advisor, with respect to both the Trust and the Fund, the Managing Owner must comply with various regulatory requirements under the Commodity Exchange Act and

the rules and regulations of the CFTC and the NFA, including investor protection requirements, antifraud prohibitions, disclosure requirements, and reporting and recordkeeping requirements. The Managing Owner also is subject to periodic inspections and audits by the CFTC and NFA.

After consideration of the exchange-traded fund, or ETF, market generally and its goals specifically, DB Commodity Services LLC, referred to as either DBCS or the Predecessor Managing Owner, made the determination that it would be in DBCS’ best interest to cease managing products in the U.S. commodities ETF space. After consideration of the ETF market generally and its goals specifically, the Managing Owner made the determination that it wanted to expand its presence in the U.S. commodities ETF space by becoming the new managing owner of the Fund. The Managing Owner also intends to launch other commodities-based ETF products in the U.S. in order to respond to developments in the market and investor preferences. The change of managing owner was effected by DBCS selling and transferring to the Managing Owner the general units of the Fund owned by DBCS, and by the substitution of the Managing Owner for DBCS as managing owner of the Trust and the Fund, which became effective as of February 23, 2015.

The Shares are not deposits or other obligations of the Managing Owner, the Trustee or any of their respective subsidiaries or affiliates or any other bank, are not guaranteed by the Managing Owner, the Trustee or any of their respective subsidiaries or affiliates or any other bank and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency.

An investment in the Shares of the Fund is speculative and involves a high degree of risk.

The principal office of the Managing Owner is located at 3500 Lacey Road, Suite 700, Downers Grove, IL 60515. The telephone number of the Managing Owner is (800) 983-0903.

PowerShares^® is a registered service mark of Invesco PowerShares Capital Management, LLC.

The Fund pays the Managing Owner a Management Fee, monthly in arrears, in an amount equal to 0.85% per annum of the daily net asset value of the Fund.

The Management Fee is paid in consideration of the Managing Owner’s commodity futures trading advisory services.

The Commodity Broker

A variety of executing brokers execute futures transactions on behalf of the Fund. Such executing brokers give-up all such transactions to Morgan Stanley & Co. LLC, a Delaware limited liability company, which serves as clearing broker, or Commodity Broker of the Fund. In its capacity as clearing broker, the Commodity Broker may execute or receive transactions executed by others and clears all of the Fund’s futures transactions and performs certain administrative and custodial services for the Fund. Morgan Stanley & Co. LLC is registered with the CFTC as a futures commission merchant and is a member of the NFA in such capacity.

The Fund pays to the Commodity Broker all brokerage commissions, including applicable exchange fees, NFA fees, give-up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities for the Fund. On average, total charges paid to the Commodity Broker are expected to be less than $7.00 per round-turn trade, although the Commodity Broker’s brokerage commissions and trading fees are determined on a contract-by-contract basis. The Managing Owner does not expect brokerage commissions and fees to exceed 0.04% of the net asset value of the Fund in any year, although the actual amount of brokerage commissions and fees in any year or any part of any year may be greater.

A round-turn trade is a completed transaction involving both a purchase and a liquidating sale, or a sale followed by a covering purchase.

Limitation of Liabilities

Your investment in the Fund is part of the assets of the Fund, and it will therefore be subject to the risks of the Fund’s trading only. You cannot lose more than your investment in the Fund, and you will not be subject to the losses or liabilities of any other fund of the Trust in

which you have not invested. We have received an opinion of counsel that the Fund is entitled to the benefits of the limitation on inter-series liability provided under the Delaware Statutory Trust Act. Each Share, when purchased in accordance with the Fifth Amended and Restated Declaration of Trust and Trust Agreement of the Trust, or the Trust Declaration, shall, except as otherwise provided by law, be fully-paid and non-assessable.

The debts, liabilities, obligations, claims and expenses of the Fund will be enforceable against the assets of the Fund only, and not against the assets of the Trust generally or the assets of any other fund of the Trust, and, unless otherwise provided in the Trust Declaration, none of the debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to the Trust generally or any other series thereof will be enforceable against the assets of the Fund, as the case may be.

Creation and Redemption of Shares

The Fund creates and redeems Shares from time-to-time, but only in one or more Baskets. A Basket is a block of 200,000 Shares. Baskets may be created or redeemed only by Authorized Participants. Except when aggregated in Baskets, the Shares are not redeemable securities. Authorized Participants pay a transaction fee of $500 in connection with each order to create or redeem a Basket. Authorized Participants may sell the Shares included in the Baskets they purchase from the Fund to other investors.

See “Creation and Redemption of Shares” for more details.

The Offering

Unless otherwise agreed to by the Managing Owner and the Authorized Participant as provided in the next sentence, the Fund issues Shares in Baskets to Authorized Participants continuously on the creation order settlement date as of 2:45 p.m., Eastern time, on the business day immediately following the date on which a valid order to create a Basket is accepted by the Fund, at the net asset value of 200,000 Shares of the Fund 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, on the date that a valid order to create a Basket is accepted by the Fund. Upon submission of a creation order, the Authorized

Participant may request the Managing Owner to agree to a creation order settlement date up to 3 business days after the creation order date.

Authorized Participants

Baskets may be created or redeemed only by Authorized Participants. Each Authorized Participant must (1) be a registered broker-dealer or other securities market participant such as a bank or other financial institution which is not required to register as a broker-dealer to engage in securities transactions, (2) be a participant in DTC, and (3) have entered into an agreement with the Fund and the Managing Owner, or a Participant Agreement. The Participant Agreement sets forth the procedures for the creation and redemption of Baskets and for the delivery of cash required for such creations or redemptions. A list of the current Authorized Participants can be obtained from the Administrator. See “Creation and Redemption of Shares” for more details.

Net Asset Value

Net asset value, in respect of the Fund, means the total assets of the Fund including, but not limited to, all cash and cash equivalents or other debt securities less total liabilities of the Fund, each determined on the basis of generally accepted accounting principles in the United States, consistently applied under the accrual method of accounting.

Net asset value per Share is the net asset value of the Fund divided by the number of its outstanding Shares.

See “Description of the Shares; The Fund; Certain Material Terms of the Trust Declaration-Net Asset Value” for more details.

Clearance and Settlement

The Shares are evidenced by global certificates that the Fund issues to DTC. The Shares are available only in book-entry form. Shareholders may hold Shares through DTC, if they are participants in DTC, or indirectly through entities that are participants in DTC.

Segregated Accounts/Interest Income

The proceeds of the offering of the Fund are deposited in cash in a segregated account in its name at the Commodity Broker (or another eligible financial institution, as applicable) in accordance with CFTC investor protection and segregation requirements. The Fund is credited with 100% of the interest earned on its average net assets on deposit with the Commodity Broker or such other financial institution each week. In an attempt to increase interest income earned, the Managing Owner expects to invest non-margin assets of the Fund in United States government securities (which include any security issued or guaranteed as to principal or interest by the United States), or any certificate of deposit for any of the foregoing, including United States Treasury bonds, United States Treasury bills and issues of agencies of the United States government, and certain cash items such as money market funds, certificates of deposit (under nine months) and time deposits or other instruments permitted by applicable rules and regulations. Currently, the rate of interest expected to be earned by the Fund is estimated to be 0.14% per annum, based upon the yield on 3-month U.S. Treasury bills as of November 15, 2015. This interest income is used by the Fund to pay its expenses. See “Fees and Expenses” for more details.

Breakeven Amounts

The estimated amount of all fees and expenses which are anticipated to be incurred by a new investor in Shares of the Fund during the first twelve months of investment is 0.89% per annum of the net asset value of the Fund, plus the amount of any commissions charged by the investor’s broker.

The Fund will be successful only if its annual returns from futures trading, plus its annual interest income from its holdings of United States Treasury securities and other high credit quality short-term fixed income securities, exceed such fees and expenses of approximately 0.89% per annum. The Fund is expected to earn interest income equal to 0.14% per annum, based upon the yield of 3-month U.S. Treasury bills as of November 15, 2015, or $0.04 per annum per Share at $25.00 as the net asset value per Share. Therefore, based upon the difference between the current yield of 3-month U.S. Treasury bills and the annual fees and expenses, the Fund will be required to earn approximately 0.75% per annum, or $0.19 per annum per Share at $25.00 as the net asset value per Share, in order for an investor to break-even on an investment during the first twelve months of an investment. Actual interest income could be higher or lower than the current yield of 3-month U.S. Treasury bills.

Distributions

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.

Fiscal Year

The fiscal year of the Fund ends on December 31 of each year.

U.S. Federal Income Tax Considerations

Subject to the discussion below in “Material U.S. Federal Income Tax Considerations,” the Fund will be classified as a partnership for U.S. federal income tax purposes. Accordingly, the Fund will not incur U.S. federal income tax liability; rather, each beneficial owner of Shares will be required to take into account its allocable share of the Fund’s income, gain, loss, deduction and other items for the Fund’s taxable year ending with or within the owner’s taxable year.

Additionally, please refer to the “Material U.S. Federal Income Tax Considerations” section below for information on the potential U.S. federal income tax consequences of the purchase, ownership and disposition of Shares.

Breakeven Table

The Breakeven Table on page 14 indicates the approximate percentage and dollar returns required for the value of an initial $25.00 investment in a Share of the Fund to equal the amount originally invested twelve months after issuance.

The Breakeven Table as presented, is an approximation only. The capitalization of the Fund does not directly affect the level of its charges as a percentage of its net asset value, other than brokerage commissions.

THE SHARES ARE SPECULATIVE AND INVOLVE A HIGH DEGREE OF RISK.

[Remainder of page left blank intentionally.]

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 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. In vacating and remanding the new position limits rules, the court nevertheless upheld the CFTC’s revisions to the legacy position limits that amended previously-enacted position limits rules are already in place pursuant to CFTC rules. On November 5, 2013, the CFTC re-proposed for public comment new position limits and an aggregation rule both of which are currently pending and have not yet been adopted. In addition, the CFTC proposed regulations that would expand certain exemptions from aggregation of accounts of related parties. The CFTC directed staff to hold a public roundtable on June 19, 2014 to discuss certain position limit and aggregation issues. In order to provide interested parties an opportunity to comment on these issues, the CFTC reopened the public comment periods for these proposed regulations until

January 22, 2015. It remains to be seen whether the CFTC will modify the proposed regulations in response to public comments.

The CFTC’s existing position limit regulations require that a trader aggregate all positions in accounts which the trader owns or over which the trader controls trading. However, a trader is not required to aggregate positions in multiple accounts or commodity pools if that trader (or its applicable divisions/subsidiaries) qualifies as an “independent account controller” under applicable CFTC regulations and avails itself of the independent account controller exemption under the regulations. The re-proposed regulations would maintain the independent account controller exemption, which the Managing Owner intends to rely upon in order to disaggregate the positions of the Fund from certain other accounts. However, if the CFTC does not adopt or renew the independent account controller exemption, or if the exemption were modified or otherwise unavailable, to the extent the Managing Owner avails itself of the exemption, it may be required to aggregate positions in multiple accounts or commodity pools for purposes of the CFTC’s position limits regulations. In that case, it is possible that investment decisions of the Managing Owner with respect to the Fund would be affected by positions maintained by the Managing Owner with respect to accounts other than for the Fund. It is likely that the Fund would be compelled to liquidate futures contracts with respect to the Affected Index Commodities to come within position limits in the aggregate with other accounts or substitute a futures contract that exhibits trading prices that tend to correlate with a futures contract with respect to an Affected Index Commodity, at the risk of variance with the Index. In addition, failure to comply with the requirements of the independent account controller exemption, if applicable, could lead to an enforcement proceeding against the Managing Owner and could adversely affect the Fund.

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. 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.

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 is currently subject to position limits and may be subject to new and expanded position limits, 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 Commodity may be impaired or limited to the extent these activities would cause the Fund to exceed its applicable position limits. Limiting the size of the Fund to stay within these position limits may affect the correlation between the price of the Shares, as traded on the NYSE Arca, and the net asset value of the Shares. The inability to create additional Baskets could result in Shares trading at a premium or discount to net asset value of the Fund.

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 manages a number of exchange-traded funds that use financial futures as part of their investment strategy and, only for a short time, has actively managed an exchange-traded fund related to a broad-based futures index. The past performance of these funds is no indication of the Managing Owner’s ability to manage exchange-traded investment vehicles that track a commodities index such as the Fund. There can be no assurance that the Managing Owner will be able to cause the net asset value per Share of the Fund to closely track the changes in the Index levels. If the experience of the Managing Owner and its principals is not relatively 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 (or might not) 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 41 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 prospers 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 the 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 United States Internal Revenue Service, or the IRS, will successfully assert that the conventions and assumptions used by the Fund do not satisfy the technical requirements of the Internal Revenue Code of 1986, as amended, or 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 Fund 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 Fund 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 a vehicle that tracks the Fund’s Index 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 mutual funds, and other investment companies, ETFs, other index tracking commodity pools, actively traded 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 gross negligence or willful 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 Securities Inc.

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 calculates and 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 calculates and publishes the intra-day Index level, and the Index Sponsor calculates, 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.invescopowershares.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.invescopowershares.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.invescopowershares.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.invescopowershares.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 trading day to reflect the continuous price changes of the Fund’s futures positions, which provide a continuously updated estimated net asset value per Share. 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 c/o Invesco PowerShares Capital Management LLC, 3500 Lacey Road, Suite 700, Downers Grove, IL 60515. The telephone number of the Managing Owner is (800) 983-0903.

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.

General

Each of the DBIQ Optimum Yield Index Excess Return™, or DBIQ-OYER™, and the DBIQ Index Excess Return™, or DBIQ ER™ (“DBIQ-OYER™” and “DBIQ ER™,” collectively, “DBIQ™” or “DBIQ ER™”), is intended to reflect the changes in market value, over time, positive or negative, in certain sectors of commodities, or an index. The Index is calculated on an excess return, or unfunded basis. The Index is rolled on both an Optimum Yield™ and non-Optimum Yield™ basis. The Optimum Yield™ rolling methodology is aimed at potentially maximizing the roll benefits in backwardated markets and minimizing the losses from rolling in contangoed markets. The non-Optimum Yield™ portion of the Index is rolled to the next to expire futures contract as provided below under “Contract Selection (Non-OY Single Commodity Indexes only).” The Index is comprised of one or more underlying commodities, or Index Commodities. Each Index Commodity is assigned a weight, or Index Base Weight, which is intended to reflect the proportion of such Index Commodity relative to the Index.

DBIQ Diversified Agriculture Index Excess Return™, or the Index, is intended to reflect the agricultural sector.

The Index has been calculated back to a base date, or Base Date. On the Base Date of January 18, 1989, the closing level of the Index, or Closing Level, was 100.

The sponsor of the Index is Deutsche Bank Securities Inc., or Index Sponsor. The Index Sponsor may from time-to-time subcontract the provision of the calculation and other services described below to one or more third parties.

[Remainder of page left blank intentionally.]

Composition of the Index

The Index is composed of notional amounts of each of the underlying Index Commodities. The notional amount of each Index Commodity included in the Index is intended to reflect the changes in market value of each such Index Commodity within the Index. The Closing Level of the Index is calculated on each business day by the Index Sponsor based on the closing price of the futures contracts for each of the underlying Index Commodities and the notional amounts of such Index Commodities.

The Index is rebalanced annually in November to ensure that each of the Index Commodities is weighted in the same proportion that such Index Commodities were weighted on the Base Date.

The composition of the Index may be adjusted in the event that the Index Sponsor is not able to calculate the closing prices of the Index Commodities.

The Index includes provisions for the replacement of futures contracts as they approach maturity. This replacement takes place over a period of time in order to lessen the impact on the market for the futures contracts being replaced. With respect to each Index Commodity, the Fund employs a rule-based approach when it ‘rolls’ from one futures contract to another. The Index is comprised of OY Single Commodity Indexes and non-OY Single Commodity Indexes. The Index Commodities that underlie the OY Single Commodity Indexes are Corn, Soybeans, Wheat, Kansas City Wheat and Sugar. The Index Commodities that underlie the non-OY Single Commodity Indexes are Cocoa, Coffee, Cotton, Live Cattle, Feeder Cattle and Lean Hogs. The OY Single Commodity Indexes are rolled to the futures contract which generates the best possible “implied roll yield.” The futures contract with a delivery month within the next thirteen months which generates the best possible implied roll yield will be included in each OY Single Commodity Index. As a result, each OY Single Commodity Index is able to potentially maximize the roll benefits in backwardated markets and minimize the losses from rolling in contangoed markets.

Each of the non-OY Single Commodity Indexes rolls only to the next to expire futures contract as provided below under “Contract Selection (Non-OY Single Commodity Indexes only)”.

In general, as a futures contract approaches its expiration date, its price will move towards the spot

price in a contangoed market. Assuming the spot price does not change, this would result in the futures contract price decreasing and a negative implied roll yield. The opposite is true in a backwardated market. Rolling in a contangoed market will tend to cause a drag on an Index Commodity’s contribution to the Fund’s return while rolling in a backwardated market will tend to cause a push on an Index Commodity’s contribution to the Fund’s return.

The Index is calculated in USD on both an excess return (unfunded) and total return (funded) basis.

The futures contract price for each Index Commodity will be the exchange closing price for such Index Commodity on each weekday when banks in New York, New York are open, or Index Business Days. If a weekday is not an Exchange Business Day (as defined in the following sentence) but is an Index Business Day, the exchange closing price from the previous Index Business Day will be used for each Index Commodity. “Exchange Business Day” means, in respect of an Index Commodity, a day that is a trading day for such Index Commodity on the relevant exchange (unless either an Index disruption event or force majeure event has occurred).

Contract Selection (OY Single Commodity Indexes only)

On the first New York business day, or Verification Date, of each month, each Index Commodity futures contract will be tested in order to determine whether to continue including it in the applicable OY Single Commodity Index. If the Index Commodity futures contract requires delivery of the underlying commodity in the next month, known as the Delivery Month, a new Index Commodity futures contract will be selected for inclusion in such OY Single Commodity Index. For example, if the first New York business day is May 1, 2016, and the Delivery Month of the Index Commodity futures contract currently in such OY Single Commodity Index is June 2016, a new Index Commodity futures contract with a later Delivery Month will be selected.

For each underlying Index Commodity of an OY Single Commodity Index, the new Index Commodity futures contract selected will be the Index Commodity futures contract with the best possible “implied roll yield” based on the closing price for each eligible Index Commodity futures contract. Eligible Index Commodity futures contracts are any Index Commodity futures contracts having a

Delivery Month (i) no sooner than the month after the Delivery Month of the Index Commodity futures contract currently in such OY Single Commodity Index, and (ii) no later than the 13^th month after the Verification Date. For example, if the first New York business day is May 1, 2016 and the Delivery Month of an Index Commodity futures contract currently in an OY Single Commodity Index is therefore June 2016, the Delivery Month of an eligible new Index Commodity futures contract must be between July 2016 and July 2017. The implied roll yield is then calculated and the futures contract on the Index Commodity with the best possible implied roll yield is then selected. If two futures contracts have the same implied roll yield, the futures contract with the minimum number of months prior to the Delivery Month is selected.

After selection of the replacement futures contract, each OY Single Commodity Index will roll such replacement futures contract as provided in the sub-paragraph “Monthly Index Roll Period with respect to both OY Single Commodity Indexes and Non-OY Single Commodity Indexes.”
