PowerShares DB Multi-Sector Commodity Trust (the “Trust”) is organized in seven separate series as a Delaware statutory trust. Each series of the Trust (each a “Fund”) issues common units of beneficial interest (“Shares”), which represent units of fractional undivided beneficial interest in and ownership of such series only. Unless the context otherwise requires, references in this Prospectus to a “Fund” or the “Funds” are to the series of the Trust that is or are being offered pursuant to this Prospectus. Shares in each Fund are being separately offered. Shares may be purchased from each Fund only by certain eligible financial institutions, called Authorized Participants, and only in one or more blocks of 200,000 Shares, called a Basket. Baskets are issued on the creation order settlement date as of 2:45 p.m., Eastern time, on the business day immediately following the creation order date at the applicable net asset value (“NAV”) per Share as of the closing time if the NYSE Arca, Inc. (“NYSE Arca”) or the last to close of the exchanges on which the Fund’s futures contracts are traded, whichever is later, on the creation order date. Upon submission of a creation order, the Authorized Participant may request the Managing Owner to agree to a creation order settlement date up to two business days after the creation order date.

Authorized Participants may sell the Shares comprising the Baskets they purchase from a Fund to other investors at prices that are expected to reflect, among other factors, the trading price of such Fund’s Shares on the NYSE Arca and the supply of and demand for Shares of such Fund at the time of sale and are expected to fall between NAV and the trading price of the Shares of such Fund on the NYSE Arca at the time of sale.

The Shares of each Fund trade on the NYSE Arca under the following symbols: PowerShares DB Energy Fund – DBE; PowerShares DB Oil Fund – DBO; PowerShares DB Precious Metals Fund – DBP; PowerShares DB Gold Fund – DGL and PowerShares DB Base Metals Fund – DBB.

Invesco PowerShares Capital Management LLC serves as each Fund’s managing owner (the “Managing Owner”), commodity pool operator and commodity trading advisor of each Fund.

Each Fund trades exchange-traded futures contracts on the commodities comprising a particular commodities index, with a view

to tracking the index over time. Each Fund also earns interest income from United States Treasury Securities (“Treasury Income”) and dividends from its holdings in money market mutual funds (affiliated or otherwise) (“Money Market Income”). Each Fund also gains an exposure to United States Treasury Securities through an investment in exchange-traded funds (affiliated or otherwise) (“ETFs”) that track indexes that measure the performance of U.S. Treasury Obligations with a maximum remaining maturity of up to twelve months(“T-Bill ETFs”), and each Fund may receive dividends or distributions of capital gains from such investment inT-Bill ETFs(“T-Bill ETF Income”). Additionally, each Fund’s performance reflects the appreciation or depreciation of its investments in United States Treasury Securities, money market mutual funds andT-Bill ETFs.

SUMMARY

This summary of material information contained or incorporated by reference in this Prospectus is intended for quick reference only and does not contain all of the information that may be important to you. For ease of reference, any references throughout this Prospectus to various actions taken by each of the Funds are actually actions that the Trust has taken on behalf of such respective Funds. The remainder of this Prospectus contains more detailed information. You should read the entire Prospectus, including the information incorporated by reference in this Prospectus, before deciding whether to invest in Shares of any Fund. Please see the section “Incorporation by Reference of Certain Documents” for information on how you can obtain the information that is incorporated by reference in this Prospectus. This Prospectus is dated March 8, 2018.

The Trust and the Funds

PowerShares DB Multi-Sector Commodity Trust (the “Trust”) was formed as a Delaware statutory trust, in seven separate series (“Funds”) on August 3, 2006. Each Fund issues common units of beneficial interest (“Shares”) which represent units of fractional undivided beneficial interest in and ownership of such Fund. The term of the Trust and each Fund is perpetual (unless terminated earlier in certain circumstances). The principal executive offices of the Trust and each 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. 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 each of the Funds listed in the prior sentence, except for PowerShares DB Silver Fund and

PowerShares DB Agriculture Fund. Information regarding the offered Funds (including any other additional series of the Trust) and both PowerShares DB Silver Fund and PowerShares DB Agriculture Fund (neither of which is offered by this Prospectus) is available atwww.powershares.com.

Shares Listed on the NYSE Arca

The Shares of each Fund are listed on the NYSE Arca under the following symbols:

•

PowerShares DB Energy Fund – DBE;

•

PowerShares DB Oil Fund – DBO;

•

PowerShares DB Precious Metals Fund – DBP;

•

PowerShares DB Gold Fund – DGL; and

•

PowerShares DB Base Metals Fund – DBB.

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

Purchases and Sales in the Secondary Market on the NYSE Arca

Individual Shares of each Fund may be purchased and sold only on the NYSE Arca. Because the Shares will trade at market prices, rather than the net asset value (“NAV”) of a Fund, Shares may trade at prices greater than NAV of such Fund (at a premium), at NAV, or less than NAV (at a discount).

Baskets may be created or redeemed directly with each Fund only by Authorized Participants. It is expected that Baskets in a Fund will be created when the market price per Share in such Fund is at a premium to the NAV per Share. Similarly, it is expected that Baskets in a Fund will be redeemed when the market price per Share of such Fund is at a discount to the NAV 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 of a Fund may not be identical to the NAV per Share, but these valuations are expected to be very close. Investors are able to use theintra-day indicative value (“IIV”) per Share to determine if they want to purchase in the secondary market via the NYSE Arca. The IIV per Share of each Fund is based on the prior day’s final NAV, adjusted four times per minute throughout the trading day to reflect the price changes of the Fund’s futures positions. As a result, the IIV provides a continuously updated estimate of each Fund’s NAV per Share.

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

Risk Factors

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

•

Past performance is not necessarily indicative of future results; all or substantially all of an investment in any Fund could be lost.

•

Each Fund’s trading of futures contracts takes place in very volatile markets.

•

Each Fund is subject to position limits from the Commodity Futures Trading Commission (“CFTC”) and/or futures exchange rules. If a Fund were to reach a position limit, its ability to issue new Baskets or to reinvest income in additional futures contracts may be impaired or limited. This may adversely affect the correlation between the market price of a Fund’s Shares and the NAV of the Fund, which could result in Shares trading at a premium or discount to the corresponding NAV.

•

There can be no assurance that any Fund will achieve profits or avoid losses, significant or otherwise.

•

Performance of a Fund may not track its Index during particular periods or over the long term. Such tracking error may cause a Fund to outperform or underperform its Index.

Disruptions in the ability to create or redeem Baskets may adversely affect investors.

•

Certain potential conflicts of interest exist between the Managing Owner, the

Commodity Broker (as defined herein) and their affiliates and each Fund’s shareholders (“Shareholders”).

Although the Managing Owner attempts to monitor for conflicts, it is extremely difficult, if not impossible, for the Managing Owner to ensure that the conflicts will not, in fact, result in adverse consequences to the Funds and the Shareholders.

•

Each Fund’s NAV may not always correspond to the market price of the Shares and, as a result, Baskets may be created or redeemed at a value that differs from the market price of the Shares.

•

Shareholders will be subject to taxation on their allocable share of each Fund’s taxable income, whether or not they receive cash distributions.

Each Fund is subject to fees and expenses in the aggregate amount of approximately 0.78% per annum for the PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund, and of approximately 0.80% for the PowerShares DB Base Metals Fund. Each Fund will be successful only if its annual returns from futures trading, plus its annual Treasury Income and any Money Market Income andT-Bill ETF Income, exceed such fees and expenses.

The Trustee

Wilmington Trust Company (the “Trustee”), a Delaware trust company, is the sole trustee of the Trust. The Trustee’s duties and liabilities with respect to the offering of the Shares and the management of the Funds are limited to its express obligations under the Fifth Amended and Restated Declaration of Trust and Trust Agreement (the “Trust Agreement”).

Investment Objective

Treasury Securities, money market mutual funds andT-Bill ETFs for margin and/or cash management purposes only and each Fund’s performance reflects the appreciation and depreciation of such securities.

The Shares of each Fund are designed for investors who want a cost-effective and convenient way to invest in commodity futures on U.S. andnon-U.S. markets.

Advantages of investing in the Funds include:

•

Ease and Flexibility of Investment. The Shares trade on the NYSE Arca and provide institutional and retail investors with indirect access to commodity futures markets. The Shares may be bought and sold on the NYSE Arca like other exchange-listed securities. Retail investors may purchase and sell Shares through traditional brokerage accounts.

•

Margin. Shares are eligible for margin accounts.

•

Diversification. The Shares may help to diversify a portfolio of other investments because historically the Indexes have tended to exhibit low to negative correlation with both equities and conventional bonds and positive correlation to inflation.

•

Optimum Yield™. The Indexes utilize an Optimum Yield™ methodology, which seeks to minimize the effects of negative roll yield that may be experienced by conventional commodities indexes. “Negative roll yield” is a term that describes the adverse impact of an upward-sloping price curve for futures contracts, which makes it more expensive to replace expiring contracts with new contracts.

•

Transparency. The Shares provide a more direct investment in commodities than mutual funds or ETFs that invest in commodity-linked notes or otherwise gain indirect exposure to commodities, which may have implicit imbedded costs, credit risk and other potentially opaque features.

Investing in a Fund does not insulate Shareholders from certain risks, including volatility

in the spot prices of commodities comprising each Index. In addition, each Fund seeks to mitigate the adverse consequences of negative roll yield and to maximize the potential benefits of positive roll yield by tracking the corresponding Index. However, the Funds may not be successful in doing so.

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

The Funds being offered pursuant to this Prospectus intend to reflect the sectors described below. Each Index is comprised of one or more underlying commodities (“Index Commodities”) intended to reflect each such sector.

•

PowerShares DB Energy Fund is designed to track the DBIQ Optimum Yield Energy Index Excess Return™(DBIQ-OY Energy ER™), which is intended to reflect the energy sector. The Index Commodities consist of Light, Sweet Crude Oil (WTI); Heating Oil; Brent Crude Oil; RBOB Gasoline and Natural Gas.

•

PowerShares DB Oil Fund is designed to track the DBIQ Optimum Yield Crude Oil Index Excess Return™(DBIQ-OY CL ER™), which is intended to reflect the changes in market value of crude oil. The single Index Commodity is Light, Sweet Crude Oil (WTI).

•

PowerShares DB Precious Metals Fund is designed to track the DBIQ Optimum Yield Precious Metals Index Excess Return™(DBIQ-OY Precious Metals ER™), which is intended to reflect the precious metals sector. The Index Commodities consist of Gold and Silver.

•

PowerShares DB Gold Fund is designed to track the DBIQ Optimum Yield Gold Index Excess Return™(DBIQ-OY GC ER™), which is intended to reflect the changes in market value of gold. The single Index Commodity is Gold.

•

PowerShares DB Base Metals Fund is designed to track the DBIQ Optimum Yield

Industrial Metals Index Excess Return™(DBIQ-OY Industrial Metals ER™), which is intended to reflect the base metals sector. The Index Commodities consist of Aluminum, Zinc and Copper – Grade A.

Each Fund trades futures contracts on the Index Commodities (“Index Contracts”) that are subject to position limits under regulations of the CFTC or futures exchange rules, as applicable. The Managing Owner may determine to invest in other futures contracts if at any time it is impractical or inefficient to gain full or partial exposure to any Index Commodity through the use of Index Contracts. These other futures contracts may or may not be based on an Index Commodity. When they are not, the Managing Owner seeks to select futures contracts that it reasonably believes tend to exhibit trading prices that correlate with an Index Contract.

As a Fund that is designed to track an Index with more than one underlying commodity approaches or reaches position limits with respect to an Index Commodity, the Fund may commence investing in Index Contracts that reference other Index Commodities. In those circumstances, the Fund may also trade in futures contracts based on commodities other than Index Commodities that the Managing Owner reasonably believes tend to exhibit trading prices that correlate with an Index Contract. As a Fund that is designed to track an Index with one underlying commodity approaches or reaches position limits with respect to an Index Commodity, the Fund may commence investing in futures contracts based on commodities other than the Index Commodity that the Managing Owner reasonably believes tend to exhibit trading prices that correlate with an Index Contract.

The Index Sponsor calculates each Index on an excess 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.

Each Fund also holds United States Treasury Securities for deposit with each Fund’s Commodity Broker as margin and has United States Treasury Securities, cash and money market mutual funds (affiliated or otherwise) on deposit with the

Custodian (for cash management purposes). Additionally, each Fund gains an exposure to United States Treasury Securities, with a maximum remaining maturity of up to 12 months, through its holdings ofT-Bill ETFs (affiliated or otherwise). Such holdings ofT-Bill ETFs are on deposit with the Custodian (for cash management purposes) and may be held by each Fund’s Commodity Broker as margin, to the extent permissible under CFTC rules.

General

Each of the DBIQ Optimum Yield Index Excess Return™ (“DBIQ-OYER™”) and the DBIQ Index Excess Return™ (“DBIQ ER™”) (collectively, “DBIQ™” or “DBIQ ER™”), is intended to reflect the changes in market value, positive or negative, in certain sectors of commodities. Each Index is calculated on an excess return, or unfunded basis. Each Index is rolled on an Optimum Yield™ basis. The Optimum Yield™ rolling is aimed at potentially maximizing the roll benefits in backwardated markets and minimizing the losses from rolling in contangoed markets. Each Index is comprised of one or more Index Commodities. The composition of Index Commodities with respect to each Index varies according to each specific sector that such Index is intended to reflect. Each Index Commodity is assigned a weight (“Index Base Weight”), which is intended to reflect the proportion of such Index Commodity relative to each Index.

DBIQ-OY CL ER™ andDBIQ-OY GC ER™ are Indexes with a single Index Commodity (“Single Commodity Sector Indexes��).

Each Index has been calculated back to a base date (“Base Date”). On the Base Date the closing level of each Index (“Closing Level”) was 100.

The sponsor of each Index is Deutsche Bank Securities Inc. (the “Index Sponsor”).

Index Composition

Each Single Commodity Sector Index is composed of one underlying Index Commodity. Each other Index is composed of notional amounts of each of the underlying Index Commodities. The notional amount of each Index Commodity included in each

multi-sector Index is intended to reflect the changes in market value of each such Index Commodity within the specific Index. The Closing Level of each Index is calculated on each Index Business Day (as defined below) 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.

With the exception of the Single Commodity Sector Indexes, each 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 each Index may be adjusted in the event that the Index Sponsor is not able to calculate the closing prices of the Index Commodities.

Each 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, each Fund employs a rule-based approach when it ‘rolls’ from one futures contract to another. Rather than select a new futures contract based on a predetermined schedule (e.g., monthly), each Index Commodity rolls to the futures contract which generates the best possible “implied roll yield” under prevailing market conditions. Where there is an upward-sloping price curve for futures contracts, the implied roll yield is expected to be negative. The selection of a new futures contract on an Index Commodity in such market conditions is designed to minimize the impact of negative roll yield. Conversely, where there is a downward-sloping price curve for futures contracts, the implied roll yield is expected to be positive. The selection of a new futures contract on the Index Commodities in such market conditions is designed to maximize the impact of positive roll yield. The Indexes take the impact of implied roll yield into consideration by selecting, as the replacement for an expiring futures contract, the futures contract with a delivery month within the next thirteen months that generates the most favorable implied roll yield under the current market conditions.

The market condition in which an Index is designed to maximize the effect of positive roll yield when entering into new futures contracts is called backwardation. Rolling in a backwardated market will tend to enhance returns from futures trading. The market condition in which the Index is designed to mitigate the effect of negative roll yield when entering into new futures contracts is called contango. Rolling in a contangoed market will tend to cause a drag on returns from futures trading.

Each Fund’s returns from futures trading is called excess return, which is the combined return based on the spot prices of the Index Commodities and the roll yield from trading futures contracts on the Index Commodity.

Contract Selection (OY Single Commodity Indexes only)

On the first Index Business Day of each month (“Verification Date”), 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 Index Business Day is May 1 of the current year, and the Delivery Month of the Index Commodity futures contract currently in such OY Single Commodity Index is June of the current year, 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 thirteenth month after the Verification Date. For example, if the first Index

Business Day is May 1 of the current year and the Delivery Month of an Index Commodity futures contract currently in an OY Single Commodity Index is therefore June of the current year, the Delivery Month of an eligible new Index Commodity futures contract must be between July of the current year and June of the following year. 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 the futures contract selection with respect to the 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 second and sixth 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 an 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 futures remains constant.

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

Monthly Index Roll Period with respect to OY Single Commodity Indexes

On each day during the roll period, new notional holdings are calculated. The calculations for the old Index Commodities that are leaving an 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 Contract remains constant.

Each Index that is not a Single Commodity Sector Index isre-weighted on an annual basis on the sixth Index Business Day of each November.

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

Shares of Each Fund Should Track Closely the Value of its Index

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

The value of the Shares of each Fund is expected to fluctuate in relation to changes in the value of its portfolio. The market price of the Shares of a Fund may not be identical to the NAV per Share, but these two valuations are expected to be very close.

Each Fund holds a portfolio of long futures contracts on each Index Commodity that comprises its corresponding Index, each of which are traded on various commodity futures markets in the United States or abroad. Each Fund also holds United States Treasury Securities for deposit with each Fund’s Commodity Broker as margin and United States Treasury Securities, cash and money market mutual funds (affiliated or otherwise) on deposit with the custodian (for margin and/or cash management purposes). In addition, each Fund gains an exposure to United States Treasury Securities with a maximum remaining maturity of up to twelve months through its holdings ofT-Bill ETFs (affiliated or otherwise). Such holdings ofT-Bill ETFs are on deposit with the custodian (for margin and/or cash management purposes) and may be held by each Fund’s Commodity Broker as margin, to the extent permissible under CFTC rules.

Each Fund’s portfolio is traded with a view to tracking the changes in its corresponding Index over time, whether the Index is rising, falling or flat over any particular period. None of the Funds is

“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 under all market conditions.

The Managing Owner

Invesco PowerShares Capital Management LLC, a Delaware limited liability company, serves as Managing Owner of the Trust and each 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 ETFs and has been managingnon-commodity futures based ETFs since 2003 and a commodity futures based ETF since 2014. The Managing Owner serves as the commodity pool operator and commodity trading advisor of the Trust and each Fund. The Managing Owner is registered as a commodity pool operator and commodity trading advisor with the CFTC, and is a member of, and approved as a swap firm by, the National Futures Association (the “NFA”). As a registered commodity pool operator and commodity trading advisor, with respect to both the Trust and each Fund, the Managing Owner must comply with various regulatory requirements under the United States Commodity Exchange Act of 1936, as amended (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.

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.

Each Fund pays the Managing Owner a Management Fee, monthly in arrears, in an amount equal to 0.75% per annum of the daily NAV of each Fund.

The Management Fee is paid in consideration of the Managing Owner’s services related to the management of the Fund’s business and affairs, including the provision of commodity futures trading advisory services.

Each Fund may, for margin and/or cash management purposes, invest in money market mutual funds and/orT-Bill ETFs that are managed by affiliates of the Managing Owner. The indirect portion of the management fees that such Fund may incur through such investments is in addition to the Management Fee paid to the Managing Owner. The Managing Owner has contractually agreed to waive the fees that it receives from each Fund in an amount equal to the indirect management fees that each Fund incurs through its investments in affiliated money market mutual funds and/or affiliatedT-Bill ETFs indefinitely.

Under the Trust Agreement, Wilmington Trust Company is the trustee of each Fund. The Trustee’s duties and liabilities with respect to the offering of each Fund’s Shares and the management of each Fund are limited to its express obligations under the Trust Agreement. The Trustee has no duty or liability to supervise or monitor the performance of the Managing Owner, nor does the Trustee have any liability for the acts or omissions of the Managing Owner.

The Commodity Broker

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

Each Fund pays 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 each Fund. On average, total charges paid to the Commodity Broker are expected to be less than $6.00 per round-turn trade (except with respect to the PowerShares DB Base Metals Fund, which is expected to be less than $13.00 per round-turn trade), although the Commodity Broker’s brokerage commissions and trading fees are determined on acontract-by-contract basis. The Managing Owner estimates the brokerage commissions and fees will be approximately:

•

0.03% of the NAV of each of PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund; and

•

0.05% of the NAV of PowerShares DB Base Metals 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.

The Administrator, Custodian and Transfer Agent

The Bank of New York Mellon is the administrator (the “Administrator”) and serves as the custodian (the “Custodian”) and transfer agent (the “Transfer Agent”) of each Fund. The Bank of New York Mellon has entered into an Administration Agreement, a Global Custody Agreement (the “Custody Agreement”), and a Transfer Agency and Service Agreement in connection therewith.

Pursuant to the Administration Agreement, the Administrator performs or supervises the performance of services necessary for the operation and administration of each Fund (other than making investment decisions), including receiving and processing orders from Authorized Participants to create and redeem Baskets, NAV calculations, accounting and other fund administrative services.

Key terms of the Administration Agreement are summarized under the heading “Material Contracts.”

The Administrator’s monthly fees are paid on behalf of each Fund by the Managing Owner out of the applicable Management Fee.

The Transfer Agent receives a transaction processing fee in connection with orders from Authorized Participants to create or redeem Baskets in the amount of $500 per order. These transaction processing fees are paid directly by the Authorized Participants and not by any Fund.

Invesco Distributors, Inc.

Invesco Distributors, Inc. (“Invesco Distributors”) assists the Managing Owner with certain functions and duties relating to distribution and marketing, including reviewing and approving marketing materials. Invesco Distributors retains all marketing materials at c/o Invesco Distributors, Inc., 11 Greenway Plaza, Suite 1000, Houston, Texas 77046-1173.

“800” Number for Investors

Investors may contact the Managing Owner toll free in the U.S. at (800)983-0903.

Limitation of Liabilities

You cannot lose more than your investment, plus any appreciation in your investment, in the Shares. Shareholders are entitled to limitation on liability equivalent to the limitation on liability enjoyed by stockholders of a Delaware business corporation for profit. An investor may be required to return some or all of its capital in the event of a bankruptcy of any Fund.

You will not be subject to the losses or liabilities of any other series of the Trust in which you have not invested. We have received an opinion of counsel that each 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, as amended from time to time (the “Trust Agreement”), shall, except as otherwise provided by law, be fully-paid andnon-assessable.

The debts, liabilities, obligations, claims and expenses of a particular Fund will be enforceable against the assets of that Fund only, and not against the assets of the Trust generally or the assets of any other series of the Trust, and, unless otherwise provided in the Trust Agreement, 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 such Fund, as the case may be.

Creation and Redemption of Shares

The Funds create and redeem 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. Baskets are created and redeemed continuously on the creation order settlement date or redemption order settlement date, as applicable, as of 2:45 p.m., Eastern time, on the business day immediately following the date on which a valid order to create or redeem a Basket is accepted by the Fund. The creation or redemption will be at the NAV of 200,000 Shares as of the closing time of the NYSE Arca or the last to close of the exchanges on which the Index Commodities are traded, whichever is later, on the date that a valid order to create or redeem a Basket is accepted by a Fund. Upon submission of a creation order or redemption order, the Authorized Participant may request the Managing Owner to agree to a creation order settlement or redemption order settlement date up to two business days after the creation order date or redemption order date.

For purposes of processing both purchase and redemption orders, a “business day” means any day other than a day when banks in New York City are required or permitted to be closed. 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 Funds to other investors.

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

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 the Depository Trust Company (“DTC”), and (3) have entered into an agreement with each Fund and the Managing Owner (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.

NAV

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

NAV per Share, in respect of any Fund, is the NAV of the Fund divided by the number of outstanding Shares.

See “Description of the Shares; The Funds; Certain Material Terms of the Trust Agreement—NAV” for more details.

Clearance and Settlement

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

Segregated Accounts/Treasury Income, Money Market Income andT-Bill ETF Income

Each Fund has arranged for the proceeds of the continuous offering of the Shares of each Fund to be deposited in cash in a segregated account in such Fund’s the name at the Custodian (or another eligible financial institution, as applicable) in accordance with CFTC investor protection and segregation requirements. Each Fund is credited with 100% of the interest earned on its average net assets on deposit with the Custodian or such other financial institution each week. The Managing Owner expects to investnon-margin assets of each 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 and United States Treasury securities, and certain cash and cash equivalent items such as money market mutual funds (affiliated or otherwise),T-Bill ETFs (affiliated or otherwise), certificates of deposit (under nine months) and time deposits or other instruments permitted by applicable rules and regulations for margin and/or cash management purposes.

See “Fees and Expenses” for more details.

Fees and Expenses


Management Fee		Each Fund pays the Managing Owner a Management Fee, monthly in arrears, in an amount equal to 0.75% per annum of its daily NAV. The Management Fee is paid in consideration of the Managing Owner’s services related to the management of each Fund’s business and affairs, including the provision of commodity futures trading advisory services. Each Fund may, for margin and/or cash management purposes, invest in money market mutual funds and/orT-Bill ETFs that are managed by affiliates of the Managing Owner. The indirect portion of the management fees that such Fund may incur through such investments is in addition to the Management Fee paid to the Managing Owner. The Managing Owner has contractually agreed to waive the fees that it receives in an amount equal to the indirect management fees that each Fund incurs through its investments in affiliated money market mutual funds and/or affiliatedT-Bill ETFs indefinitely.
Offering Expenses		Expenses incurred in connection with the continuous offering of Shares are paid by the Managing Owner.
Brokerage Commissions and Fees		Each 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 its trading activities. On average, total charges paid to the Commodity Broker are expected to be less than $6.00 per round-turn trade (except with respect to the PowerShares DB Base Metals Fund, which is expected to be less than $13.00 per round-turn trade), although the Commodity Broker’s brokerage commissions and trading fees are determined on acontract-by-contract basis. The Managing Owner estimates the brokerage commissions and fees will be approximately (i) 0.03% of the NAV of each Fund with respect to PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund and (ii) 0.05% of the NAV with respect to PowerShares DB Base Metals 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.
Routine Operational, Administrative and Other Ordinary Expenses		The Managing Owner pays all of the routine operational, administrative and other ordinary expenses of each Fund, including, but not limited to, computer services, the fees and expenses of the Trustee, license and service fees paid to Deutsche Bank Securities Inc. (“DBSI”), as Marketing Agent and Index Sponsor, legal and accounting fees and expenses, tax preparation expenses, filing fees, and printing, mailing and duplication costs.
Non-Recurring Fees and Expenses		Each Fund pays allnon-recurring and unusual fees and expenses (referred to as extraordinary fees and expenses in the Trust Agreement), if any, as determined by the Managing Owner.Non-recurring and unusual fees and expenses are fees and expenses which arenon-recurring and unusual in nature, such as legal claims and liabilities, litigation costs or indemnification or other unanticipated expenses.Non-recurring and unusual fees and expenses will also include material expenses which are not currently anticipated obligations of any Fund or of managed futures funds in general. Routine operational, administrative and other ordinary expenses will not be deemednon-recurring expenses.


Management Fee and Expenses to be Paid First out of Treasury Income, Money Market Income and/orT-Bill ETF Income		The Management Fee and the brokerage commissions and fees of each Fund are paid first out of Treasury Income from such Fund’s holdings of United States Treasury Securities, Money Market Income from such Fund’s holdings of money market mutual funds (affiliated or otherwise) andT-Bill ETF Income from such Fund’s holdings ofT-Bill ETFs (affiliated or otherwise), as applicable, on deposit with the Commodity Broker as margin, the Custodian, or otherwise. If the sum of the Treasury Income, the Money Market Income and theT-Bill ETF Income is not sufficient to cover the fees and expenses of each Fund during any period, the excess of such fees and expenses over such Treasury Income, Money Market Income andT-Bill ETF Income will be paid out of income from futures trading, if any, or from sales of the Fund’s holdings in United States Treasury Securities, money market mutual funds, and/or holdings inT-Bill ETFs.
Selling Commission		Retail investors may purchase and sell Shares through traditional brokerage accounts. Investors are expected to be charged a commission by their brokers in connection with purchases of Shares that will vary from investor to investor. Investors are encouraged to review the terms of their brokerage accounts for applicable charges.

Distributions

Each Fund will make distributions at the discretion of the Managing Owner. To the extent that a Fund’s actual and projected Treasury Income, the Fund’s actual and projected Money Market Income and the Fund’s actual and projectedT-Bill ETF Income, as applicable, exceed the actual and projected fees and expenses of such Fund, the Managing Owner expects periodically to make distributions of the amount of such excess. The Managing Owner currently does not expect to make distributions with respect to capital gains for any of the Funds. Depending on the applicable 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 such 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 each 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,” each of the Funds will be classified as a partnership for U.S. federal income tax purposes. Accordingly, a Fund will generally not incur U.S. federal income tax liability; rather, each beneficial owner of a Fund’s Shares will be required to take into account its

allocable share of such Fund’s income, gain, loss, deduction and other items for the Fund’s taxable year ending with or within the owner’s taxable year.

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 of a Fund.

Breakeven Amounts

As long as each of the following Funds do not lose at least approximately 0.55% per annum, or $0.13 per annum per Share at $25.00 as the NAV per Share, from futures trading, an investor will break even on an investment during the first twelve months of an investment: PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund.

As long as the PowerShares DB Base Metals Fund does not lose at least approximately 0.53% per annum, or $0.12 per annum per Share at $25.00 as the NAV per Share, from futures trading, an investor will break even on an investment during the first twelve months of an investment.

THE SHARES ARE SPECULATIVE AND

INVOLVE A HIGH DEGREE OF RISK.

[Remainder of page left blank intentionally.]

RISK FACTORS

You could lose money investing in 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.

MARKET RISKS

NAV 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.

Shares may trade at, above or below their NAV. The NAV fluctuates with changes in the market value of a Fund’s assets. The trading price of Shares fluctuates in accordance with changes in the NAV, intraday changes in the value of the futures contracts and market supply and demand. The amount of the discount or premium in the trading price of the Shares relative to their NAV may be influenced bynon-concurrent trading hours between NYSE Arca (the exchange on which the Shares trade) and the exchanges on which the Index Contracts trade. While the Shares are expected to trade on NYSE Arca until 4:00 p.m. (Eastern time), liquidity in the markets for the Index Contracts are expected to be reduced whenever the principal markets for those contracts are closed. As a result, trading spreads, and the resulting premium or discount on Shares, may widen during these gaps in market trading hours.

The NYSE Arca May Halt Trading in the Shares Which Would Adversely Impact Your Ability to Sell Shares.

The Shares are listed for trading on the NYSE Arca under the market symbols DBE, DGL, DBO, DBP, and DBB. Trading in Shares 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 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. A Fund will be terminated if its Shares are delisted.

The Lack of An Active Trading Market for the Shares May Result in Losses on Your Investment at the Time of Disposition of Your Shares.

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 the price you would receive if an active market did exist.

Price Volatility May Cause the Total Loss of Your Investment.

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 any of the Funds. The following table sets forth the average annual volatility of each Index. Average annual volatility is the average of an Index’s volatility each year since its inception:


Fund	Index	Average Annual Volatility
PowerShares DB Energy Fund	DBIQ-OY Energy ER™	23.87%
PowerShares DB Oil Fund	DBIQ-OY CL ER™	26.39%
PowerShares DB Precious Metals Fund	DBIQ-OY Precious Metals ER™	15.46%
PowerShares DB Gold Fund	DBIQ-OY GC ER™	14.25%
PowerShares DB Base Metals Fund	DBIQ-OY Industrial Metals ER™	17.96%

Withdrawal from Participation by Authorized Participants May Affect the Liquidity of Shares.

If one or more Authorized Participants withdraws from participation, it may become more difficult to create or redeem Baskets, which may reduce the liquidity of the Shares. If it becomes more difficult to create or redeem Baskets, the correlation between the price of the Shares and the NAV may be affected, which may affect the trading market for the Shares. Having fewer participants in the market for

the Shares could also adversely affect the ability to arbitrage any price difference between the futures contracts and the Shares, which may affect the trading market and liquidity of the Shares.

Possible Illiquid Markets May Exacerbate Losses.

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 currencies or major commodities exports, can also make it difficult to liquidate a position.

There can be no assurance that market illiquidity will not cause losses for the Funds. The large size of the positions which a 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.

Trading on Futures Exchanges Outside the United States is Not Subject to U.S. Regulation.

The PowerShares DB Base Metals Fund’s and the PowerShares DB Energy Fund’s trading is expected to be conducted on futures 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.

In addition, trading onnon-U.S. exchanges is subject to the risks presented by exchange controls, expropriation, increased tax burdens and exposure to local economic declines and political instability, among other factors. An adverse development with respect to any of these factors could reduce the profit or increase the loss earned on these Funds’ trades onnon-U.S. exchanges.

Trading on Commodity Exchanges Outside the United States is Not Subject to U.S. Regulation.

A portion of the Fund’s trades may take place on markets or exchanges outside the United States.

Trading on futures exchanges outside the United States 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 to had the Fund’s trading been limited to U.S. markets.

The Effect of Market Disruptions and Government Interventions Are Unpredictable and May Have an Adverse Effect on the Value of Your Shares.

The commodity futures markets may be subject to temporary distortions due to various factors, including lack of liquidity, congestion, disorderly closing periods, manipulation and disruptive conduct, limitations on deliverable supplies, the participation of speculators, government regulation and intervention, technical and operational or system failures, nuclear accidents, terrorism, riots and acts of God.

Government 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. 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 financial crisis of 2008-2009 and associated regulatory changes, including the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd Frank Act”), are generally considered to have contributed to less credit being available to financial market participants. This is particularly the case for credit extended by banks and other traditional lending sources. The Funds do not borrow from lenders for the purpose of pursuing their investment objective. Nonetheless, restrictions on the availability of credit may adversely affect investors who borrow

to purchase Fund shares and participants in the markets for financial instruments in which the Funds trades, including futures markets. Restrictions on credit, whether in stressed market conditions or otherwise, may have a material adverse effect on investors and financial market participants, which in turn could affect a Fund’s ability to pursue its investment objective. Among other things, fewer prospective investors may adversely affect a Fund’s asset levels, and fewer financial market participants may reduce liquidity and adversely affect pricing for the financial instruments that the Fund seeks to trade.

In addition, U.S. futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices that may occur during a single business day. These limits are generally referred to as “daily price fluctuation limits,” and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a “limit price.” Once the limit price has been reached in a particular contract, it is possible that no trades may be made at a different price. It is not certain how long any such price limits would remain in effect. Limit prices may have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices, consequently affecting the value of the futures contracts.

The Funds 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 or liquidate positions against which the markets are moving. The large size of the positions which the Funds 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 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, including the Funds. Market disruptions may from time to time cause dramatic losses, and such events can result in otherwise historicallylow-risk strategies performing with unprecedented volatility and risk.

An Investment in the Shares May Be Adversely Affected by Competition From Other Methods of Investing in Commodities.

The Funds compete 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 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.

The NAV Calculation of the Funds May Be Overstated or Understated Due to the Valuation Method Employed When a Settlement Price is not Available on the Date of NAV Calculation.

Calculating the NAV of the Funds includes, in part, any unrealized profits or losses on open commodity futures contracts. Under normal circumstances, the NAV of each of the Funds reflects the settlement price of open commodity futures contracts on the date when the NAV 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. In such a situation, there is a risk that the calculation of the NAV of the relevant 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, there is a risk that the resulting calculation of the NAV of the Funds could be under or overstated, perhaps to a significant degree.

FUTURES RISKS

Fluctuations in the Price of Assets Held by the Funds Could Have a Materially Adverse Effect on the Value of an Investment in Shares.

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

•

Global supply and demand of each of the Index Commodities, which may be influenced by such factors as forward selling by the various commodities producers, purchases made by the commodities’ producers to unwind their hedge positions and production and cost levels in the major markets of each of the Index Commodities;

•

Domestic and foreign interest rates and investors’ expectations concerning interest rates;

•

Domestic and foreign inflation rates and investors’ expectations concerning inflation rates;

•

Investment and trading activities of mutual funds, ETFs,closed-end funds, hedge funds and commodity funds;

•

Weather and other environmental conditions;

•

Acts of God; and

•

Global or regional political, economic or financial events and situations.

Fewer Representative Commodities May Result in Greater Index Volatility.

Each of the indexes is concentrated in terms of the number of commodities represented. Each of PowerShares DB Energy Fund, PowerShares DB Precious Metals Fund and PowerShares DB Base Metals Fund is concentrated in five or fewer commodities and each of PowerShares DB Oil Fund

and PowerShares DB Gold Fund is concentrated in a single commodity. 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 each Index and the NAV of each Fund which tracks the corresponding Index under specific market conditions and over time.

Because the Futures Contracts Have No Intrinsic Value, the Positive Performance of Your Investment Is Wholly Dependent Upon an Equal and Offsetting Loss.

Trading in futures contracts transfers the risk of future price movements from one market participant to another. For every gain in futures trading, there is an equal and offsetting loss rather than an opportunity to participate over time in general economic growth. Futures contracts reflect, in the case of cash-settled contracts, certain rights to receive payment or obligations to make payments to the other party to the contract. In the case of physically-settled contracts, a futures contract is an agreement to make or take delivery of a particular asset at a specified price. Overall stock and bond prices could rise significantly and the economy as a whole could prosper while a Fund experiences losses as a result of pursuing its investment objective through trading futures contracts in Index Commodities.

Failure of Commodity Futures Markets to Exhibit Low to Negative Correlation to General Financial Markets Will Reduce Benefits of Diversification and May Exacerbate Losses to Your Portfolio.

Historically, commodity futures returns have tended to exhibit low to negative correlation with the returns of other assets such as stocks and bonds. Commodity futures contracts can provide a diversification benefit to investor portfolios because of their low to negative correlation with other financial assets. However, the fact that the Indexes are not inversely correlated with financial assets such as stocks and bonds means that the Funds will not necessarily be profitable during unfavorable periods for the stock or bond market. If the Shares perform in a manner that correlates with the stock or bond markets or otherwise do not perform successfully, the

Shares may not provide any diversification from losses in those markets. In such a scenario, the Shares may produce no gains to offset your losses from investments in stocks, bonds, or related assets.

“Backwardation” or “Contango” in the Market Prices of the Index Commodities Will Affect the Value of Your Shares.

As the futures contracts that underlie an Index near expiration, they are replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in August of the current year may specify an October of that year expiration. As that contract nears expiration, it may be replaced by selling the October of the current year contract and purchasing the contract expiring in December of that year. This process is referred to as “rolling.” Historically, the prices of certain Index Commodities may have been higher for contracts with shorter-term expirations than for contracts with longer-term expirations, which is referred to as “backwardation.” In these circumstances, absent other factors, the sale of the October contract would take place at a price that is higher than the price at which the December contract is purchased, thereby creating a gain in connection with rolling. While the prices or certain Index Commodities may have historically exhibited consistent periods of backwardation, backwardation will likely not exist in these markets at all times. The absence of backwardation in such Index Commodities will adversely affect the value of an Index and, accordingly, decrease the value of your Shares.

Conversely, certain of the Index Commodities historically exhibit “contango” markets rather than backwardation. Contango markets are those in which the prices of contracts are higher in the distant delivery months than in the nearer delivery months due to the costs of long-term storage of a physical commodity prior to delivery or other factors. Although certain of the Index Commodities may have historically exhibited consistent periods of contango, contango will likely not exist in these markets at all times. Contango in the Index Commodities will adversely affect the value of an Index and, accordingly, decrease the value of your Shares.

The Funds’ returns from futures trading are called excess return, which is the combined return

based on the spot prices of Index Commodities and the roll yield from trading futures contracts on Index Commodities. Rolling in a backwardated market will tend to enhance returns from futures trading. Rolling in a contangoed market will tend to cause a drag on returns from futures trading. The selection of a new futures contract on an Index Commodity is designed to minimize the impact of negative roll yield and to maximize the impact of positive roll yield in prevailing market conditions.

Although the roll method of the Indexes may minimize the roll losses due to contango and may maximize the roll benefits due to backwardation, there can be no assurance that this outcome will occur.

INDEX RISKS

A Fund’s Performance May Not Always Replicate the Changes in the Levels of its Index.

It is possible that a Fund’s performance may not fully replicate the changes in levels of the corresponding Index due to disruptions in the markets for the relevant Index Commodities, the imposition of position limits, or due to other extraordinary circumstances. The CFTC and/or certain futures exchanges impose position limits on Index Contracts. The Managing Owner may determine to invest in other futures contracts if at any time it is impractical or inefficient to gain full or partial exposure to an Index Commodity through the use of Index Contracts. These other futures contracts may or may not be based on an Index Commodity. When they are not, the Managing Owner may seek to select futures contracts that it reasonably believes tend to exhibit trading prices that correlate with an Index Contract. As a Fund approaches or reaches position limits with respect to an Index Commodity, the Fund may commence investing in Index Contracts that reference other Index Commodities. In those circumstances, a Fund may also trade in futures contracts based on commodities other than Index Commodities that the Managing Owner reasonably believes tend to exhibit trading prices that correlate with an Index Contract. In addition, the Funds may not be able to replicate the changes in levels of the corresponding Index because the total return generated by the Funds is reduced by expenses and transaction costs, including those incurred in

connection with the Funds’ trading activities, and increased by, as applicable, Treasury Income, Money Market Income andT-Bill ETF Income held for margin and/or cash management purposes. Tracking an Index requires trading of the corresponding 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 Funds Are Not Actively Managed and Track the Indexes During Periods in Which any of the Indexes Is Flat or Declining as Well as When any of the Indexes Is Rising.

None of the Funds is actively managed by traditional methods. Therefore, if positions in any one or more of the Index Commodities are declining in value, a Fund will not close out such positions, except in connection with a change in the composition or weighting of the corresponding Index. The Managing Owner seeks to cause the NAV to track each Index during periods in which the Index is flat or declining as well as when the Index is rising.

Unusually LongPeak-to-Valley Drawdown Periods With Respect To the Indexes May Be Reflected in Equally LongPeak-to-Valley Drawdown Periods with Respect to the Performance of the Shares.

“Peak-to-valley drawdown” represents the cumulative percentage decline inmonth-end NAV per Share due to losses sustained during any period in which the initialmonth-end NAV per Share is not equaled or exceeded by a subsequentmonth-end NAV per Share.

Although past Index levels are not necessarily indicative of future Index levels, thepeak-to-valley drawdown periods that the Indexes have experienced have been unusually long and have lasted for multi-year drawdown periods. Please see the charts beginning on page 34 for information regarding worstpeak-to-valley drawdown periods with respect to each Index.

Because it is expected that each Fund’s performance will track the change of its underlying Index, the Fund would experience a continuous drawdown during the period that its underlying Index experiences such a drawdown period. The value of your Shares will also decrease during such a period.

REGULATORY RISKS

Regulatory and Exchange Position Limits and Other Rules May Restrict the Creation of Baskets and the Operation of the Funds.

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

The Indexes are composed of Index Commodities, which are all subject to position limits imposed by the rules of the CFTC and/or futures exchanges on which the futures contracts for the applicable Index Commodities are traded. On November 5, 2013, the CFTC proposed for public comment new position limits and aggregation regulations. In December 2016, the CFTCre-proposed the rules on position limits with respect to 25 physical delivery commodity futures and options contracts, as well as to swaps that are economically equivalent to such contracts, referred to herein as the Position Limit Rules. There-proposed position limits would apply with respect to contracts traded on all U.S. and certain foreign exchanges on an aggregate basis. In addition, under the Position Limit Rules, the CFTC has also proposed amendments to the requirement that U.S. futures exchanges establish corresponding position limits. There-proposed Position Limit Rules are based on the position limit rules previously proposed in 2013 by the CFTC. In December 2016, the CFTC also adopted final position aggregation regulations requiring that all accounts owned or managed by an entity that is responsible for such accounts’ trading decisions, their principals and their affiliates would be aggregated for position limit purposes, referred to herein as the Aggregation Rules. The Position Limit Rules were published in the Federal Register on December 30, 2016, and the final Aggregation Rules became effective on February 14, 2017. CFTC staff subsequently issued CFTC LetterNo. 17-37, which provides time-limitedno-action relief from compliance with certain requirements under the final Aggregation Rules and clarification on the meaning of certain terms used throughout the final Aggregation Rules. The relief therein expires on August 12, 2019.

The CFTC’s Aggregation Rules 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 the Aggregation Rules and avails itself of the independent account controller exemption under the Aggregation Rules. Failure to comply with the requirements of the independent account controller or other exemption, if applicable, could lead to the Managing Owner being required to aggregate positions in multiple accounts or commodity pools for purposes of the CFTC’s or a futures exchange’s position limits rules, or an enforcement proceeding against the Managing Owner, and could adversely affect the Funds.

Generally, 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 any of a Fund’s trading may be approaching any of these position limits, the Fund may reduce its trading in the corresponding commodity futures contracts or may trade futures contracts in other commodities that the Managing Owner determines will best position the Fund to meet its investment objective. 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 Funds.

As of January 3, 2018, MiFID II requires regulatory agencies of member states in the European Union to impose position limits on certain futures contracts. Pursuant to the Markets in Financial Instruments Directive II (“MiFID II”), the UK Financial Conduct Authority has established position limits applicable to Copper, Zinc and Aluminum derivative contracts traded on the London Metal Exchange (“LME”). LME may also impose accountability levels in certain contracts. If any of the Funds were to trade futures contracts on other exchanges in the European Union, position limits may apply to such trading activity pursuant MiFID II as implemented in the relevant national laws and regulations of member states.

Exchanges may also establish accountability levels applicable to futures contracts. An exchange may order a person who holds or controls a position in excess of a position accountability level not to further increase its position, to comply with any prospective limit that exceeds the size of the position owned or controlled, or to reduce any open position that exceeds the position accountability level if the exchange determines that such action is necessary to maintain an orderly market. Position accountability levels could adversely affect a Fund’s ability to establish and maintain positions in commodity futures contracts to which such levels apply, if any of the Funds were to trade in such contracts.

The Funds are currently subject to position limits and may be subject to new and more restrictive position limits in the future. As a result, the Funds may not be able to issue new Baskets or reinvest income in additional commodity futures contracts to the extent position limits restrict their ability to establish new futures positions or add to existing positions. Limiting the size of the Funds to stay within these position limits may affect the correlation between the price of the Shares, as traded on the NYSE Arca, and the NAV of the Shares.

Failure of Futures Commission Merchants or Commodity Brokers to Segregate Assets May Increase Losses; Despite Segregation of Assets, the Funds Remain at Risk of Significant Losses Because the Funds May Only Receive aPro-Rata Share of the Assets or No Assets at All.

The Commodity Exchange Act requires a futures commission merchant to segregate all funds received from customers from such futures commission merchant’s proprietary assets. If the Commodity Broker fails to segregate customer assets as required, the assets of the Funds 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 Funds 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 Funds may not recover any assets at all, even though certain property specifically traceable to the Funds 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.”

The Commodity Exchange Act requires a clearing organization approved by the CFTC as a derivatives clearing organization to segregate all funds and other property received from a clearing member’s customers in connection with U.S. futures and options contracts from any funds held at the clearing organization to support the clearing member’s proprietary trading. Nevertheless, customer funds held at a clearing organization in connection with any futures or options contracts may be held in a commingled omnibus account, which may not identify the name of the clearing member’s individual customers. With respect to futures and options contracts, a clearing organization may use assets of anon-defaulting customer held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. In the event of a default of the clearing futures commission merchant’s other clients or the clearing futures commission merchant’s failure to extend its own funds in connection with any such default, a customer may not be able to recover the full amount of assets deposited by the clearing futures commission merchant with the clearing organization on the customer’s behalf.

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

Regulatory Changes or Actions, Including the Implementation of the Dodd-Frank Act, May Alter the Operations and Profitability of the Funds.

The regulation of commodity interest transactions and markets, including under the Dodd-Frank Act, is a rapidly changing area of law and is subject to ongoing modification by governmental and judicial action. In particular, the Dodd-Frank Act has expanded the regulation of markets, market participants and financial instruments. The new regulatory regime under the Dodd-Frank Act has imposed new compliance and legal burdens on participants in the markets for futures and other commodity interests. For example, under the Dodd-Frank Act new capital and risk requirements have

been imposed on market intermediaries. Those requirements may cause the cost of trading to increase for market participants, like the Funds, that must interact with those intermediaries to carry out their trading activities. These increased costs can detract from each Fund’s performance.

Each Fund is Subject to Extensive Regulatory Reporting and Compliance.

Each Fund is subject to a comprehensive scheme of regulation under the federal commodity futures trading and securities laws. The Funds could be subject to sanctions for a failure to comply with those requirements, which could adversely affect the Funds’ financial performance (in the case of financial penalties) or ability to pursue its investment objective (in the case of a limitation on its ability to trade).

Because the Shares are publicly traded, each Fund is subject to certain rules and regulations of federal, state and financial market exchange entities charged with the protection of investors and the oversight of companies whose securities are publicly traded. These entities, including the Public Company Accounting Oversight Board (the “PCAOB”), the SEC, the CFTC and NYSE-ARCA, have in recent years issued new requirements and regulations, most notably the Sarbanes-Oxley Act of 2002. From time to time, since the adoption of the Sarbanes-Oxley Act of 2002, these authorities have continued to develop additional regulations or interpretations of existing regulations. The Funds’ ongoing efforts to comply with these regulations and interpretations have resulted in, and are likely to continue resulting in, a diversion of management’s time and attention from revenue-generating activities to compliance related activities.

The Funds are responsible for establishing and maintaining adequate internal control over financial reporting. Each Fund’s internal control system is designed to provide reasonable assurance to its management regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective may provide only reasonable assurance with respect to financial statement preparation and presentation.

Current Discussions between the SEC and PricewaterhouseCoopers LLP regarding PricewaterhouseCoopers LLP’s Independence Could Have Potentially Adverse Consequences for the Funds.

PricewaterhouseCoopers LLP informed the Funds that it has identified an issue related to its independence under Rule2-01(c)(1)(ii)(A) of RegulationS-X (referred to as the Loan Rule). The Loan Rule prohibits accounting firms, such as PricewaterhouseCoopers LLP, from being deemed independent if they have certain financial relationships with their audit clients or certain affiliates of those clients. Each Fund is required under various securities laws to have its financial statements audited by an independent accounting firm.

The Loan Rule specifically provides that an accounting firm would not be independent if it or certain affiliates and covered persons receive a loan from a lender that is a record or beneficial owner of more than ten percent of an audit client’s equity securities (referred to as a “more than ten percent owner”). For purposes of the Loan Rule, audit clients include the Funds as well as all registered investment companies advised by the Managing Owner and its affiliates, including other subsidiaries of the Managing Owner’s parent company, Invesco Ltd. (collectively, the “Invesco Fund Complex”). PricewaterhouseCoopers LLP informed the Funds it has and certain affiliates and covered persons have relationships with lenders who hold, as record owner, more than ten percent of the shares of certain funds within the Invesco Fund Complex, which may implicate the Loan Rule.

On June 20, 2016, the SEC Staff issued a“no-action” letter to another mutual fund complex (see Fidelity Management & Research Company et al.,No-Action Letter) related to the audit independence issue described above. In that letter, the SEC confirmed that it would not recommend enforcement action against a fund that relied on audit services performed by an audit firm that was not in compliance with the Loan Rule in certain specified circumstances. In connection with prior independence determinations, PricewaterhouseCoopers LLP communicated, as contemplated by theno-action letter, that it believes that it remains objective and impartial and that a reasonable investor possessing all the facts would

conclude that PricewaterhouseCoopers LLP is able to exhibit the requisite objectivity and impartiality to report on each Fund’s financial statements as the independent registered public accounting firm. PricewaterhouseCoopers LLP also represented that it has complied with PCAOB Rule 3526(b)(1) and (2), which are conditions to the Funds relying on the no action letter, and affirmed that it is an independent accountant within the meaning of PCAOB Rule 3520. Therefore, the Managing Owner, the Funds and PricewaterhouseCoopers LLP concluded that PricewaterhouseCoopers LLP could continue as the Funds’ independent registered public accounting firm. The Invesco Fund Complex relied upon theno-action letter in reaching this conclusion.

If in the future the independence of PricewaterhouseCoopers LLP is called into question under the Loan Rule by circumstances that are not addressed in the SEC’sno-action letter, the Funds will need to take other action in order for the Funds’ filings with the SEC containing financial statements to be deemed compliant with applicable securities laws. Such additional actions could result in additional costs, impair the ability of the Funds to issue new shares or have other material adverse effects on the Funds. The SECno-action relief was initially set to expire eighteen (18) months from issuance but has been extended by the SEC without an expiration date, except that theno-action letter will be withdrawn upon the effectiveness of any amendments to the Loan Rule designed to address the concerns expressed in the letter.

TAX RISKS

Shareholders Will Be Subject to Taxation on Their Allocable Share of a Fund’s Taxable Income, Whether or Not They Receive Cash Distributions.

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 a 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 a Fund’s taxable income or even the tax liability that results from such income.

Items of Income, Gain, Loss and Deduction With Respect to Shares Could Be Reallocated if the IRS Does Not Accept the Assumptions or Conventions Used by the Funds in Allocating Such Items.

U.S. federal income tax rules applicable to partnerships are complex and often difficult to apply to publicly traded partnerships. The Funds 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 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 (the “IRS”) will successfully assert that the conventions and assumptions used by the Funds do not satisfy the technical requirements of the Internal Revenue Code of 1986, as amended (the “Code”), and/or the Federal Tax Regulations codified under 26 C.F.R., referred to herein as the 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.

The Tax Cuts and Jobs Act (the “Tax Act”) Makes Significant Changes to U.S. Federal Income Tax Rules.

The Tax Act makes significant changes to the U.S. federal income tax rules for taxation of individuals and corporations, generally effective for taxable years beginning after December 31, 2017. Most of the changes applicable to individuals are temporary and would apply only to taxable years beginning after December 31, 2017 and before January 1, 2026. In particular for individuals, the Tax Act establishes for taxable years beginning after December 31, 2017 and before January 1, 2026 a 20% deduction for “qualified publicly traded partnership income” within the meaning of Section 199A(e)(5) of the Code. Qualified publicly traded partnership income includes a Fund’s income effectively connected with the Fund’s trade or business, but does not include certain investment income. In light of the very recent enactment of the new rules regarding such deduction, the lack of guidance interpreting such rules, and the expected character of the income of the Funds, it is unclear

whether any of a Fund’s income will be eligible for the deduction. Potential investors should consult their tax advisors regarding the availability of such deduction for their allocable share of a Fund’s items of income, gain, deduction and loss.

PROSPECTIVE INVESTORS ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISORS 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.

OTHER RISKS

An Insolvency Resulting From Another Series of the Trust or the Trust Itself May Have a Material Adverse Effect on the Funds.

Each 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 each Fund are 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 Funds 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 Funds 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 Funds. The material risks associated with the Sectors Funds have not been included in this prospectus.

Disruptions in the Ability to Create and Redeem Baskets May Adversely Affect Investors.

It is generally expected that the public trading price per Share will track the NAV per Share closely over time. The relationship between the public trading price per Share and the NAV per Share depends, to a considerable degree, on the ability of Authorized Participants or their clients or customers to purchase and redeem Baskets in the ordinary course. If the process for creating or redeeming

Shares is impaired for any reason, Authorized Participants and their clients or customers may not be able to purchase and redeem Baskets or, even if possible, may choose not to do so. The inability to purchase and redeem Baskets, or the partial impairment of the ability to purchase and redeem Baskets, could result in Shares trading at a premium or discount to the NAV of each Fund. Such a premium or discount could be significant, depending upon the nature or duration of the impairment.

If any of the Funds were to issue all Shares registered in this offering, it would not be able to create new Baskets until it registered additional Shares and those additional Shares became available for sale. An inability to create new Baskets could increase the possibility that the trading price per Share would not track closely the NAV per Share. In addition, any of the Funds may, in its discretion, suspend the creation of Baskets. Suspension of creations may adversely affect how the Shares are traded and could cause Shares to trade at a premium or discount to the NAV of a Fund, perhaps to a significant degree.

The Shares Could Decrease in Value if Unanticipated Operational or Trading Problems Arise.

The mechanisms and procedures governing the creation, redemption and offering of the Shares have been developed specifically for the Funds. Consequently, there may be unanticipated problems with respect to the mechanics of the operations of the Funds and the trading of the Shares that could have a material adverse effect on an investment in the Shares. To the extent that unanticipated operational or trading problems arise, the Managing Owner’s past experience and qualifications may not be suitable for solving those problems.

While the Managing Owner manages a number of ETFs that use futures contracts as part of their investment strategy, it has only managed the Funds for a limited period of time. The Managing Owner’s limited experience with the Funds and other similar funds may adversely affect its ability to manage the Funds in accordance with its investment objective.

Historical Performance of the Funds and the Indexes is Not Indicative of Future Performance.

Past performance of any of the Funds or Indexes is not necessarily indicative of future results.

Therefore, past performance of the Funds or the Indexes should not be relied upon in deciding whether to buy Shares of any of the Funds.

Fees and Expenses May Deplete the Funds’ Assets if the Funds’ Investment Performance is Not Favorable.

Each Fund pays fees and expenses regardless of its investment performance. Such fees and expenses include asset-based fees of 0.75% per annum. Additional charges include brokerage fees of approximately 0.03% of the NAV of PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund, and 0.05% of the NAV of PowerShares DB Base Metals Fund per annum in the aggregate and selling commissions. Selling commissions are not included in any of the Funds’ breakeven calculation. The sum of a Fund’s Treasury Income, Money Market Income and/orT-Bill ETF Income may not exceed its fees and expenses. If such income does not exceed its fees and expenses, in order to break even, a Fund’s futures trading activity will need to have a favorable performance that exceeds the difference between the sum of the Fund’s Treasury Income, Money Market Income and/orT-Bill ETF Income and its fees and expenses. If a Fund’s futures trading performance is not sufficiently favorable, the Fund’s expenses could deplete its assets over time. In such a scenario, the value of your Shares will decrease.

There may be circumstances that could prevent the Funds from being operated in a manner consistent with its investment objective.

There may be circumstances outside the control of the Managing Owner and/or the Funds that make it, for all practical purposes, impossible tore-position the Funds and/or to process a purchase or redemption order. Examples of such circumstances include: natural disasters; public service disruptions or utility problems such as those caused by fires, floods, extreme weather conditions, and power outages resulting in telephone, telecopy, and computer failures; market conditions or activities causing trading halts; systems failures involving computer or other information systems affecting the aforementioned parties, as well as DTC, or any other participant in the purchase process, and similar extraordinary events. While the Managing Owner has

established and implemented a disaster recovery plan, circumstances such as those identified above may prevent the Funds from being operated in a manner consistent with its investment objective.

You May Be Adversely Affected by Redemption Orders that Are Subject To Postponement, Suspension or Rejection Under Certain Circumstances.

The Managing Owner may, in its discretion, suspend the right of redemption or postpone the redemption order settlement date, for (1) any period during which an emergency exists as a result of which the redemption distribution is not reasonably practicable, or (2) such other period as the Managing Owner determines to be necessary for the protection of the Shareholders. In addition, the Funds will reject a redemption order if the order is not in proper form as described in the participant agreement among the Authorized Participant, the Managing Owner, either in its own capacity or in its capacity as managing owner of the Funds, 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 NAV of a Fund declines during the period of delay. The Funds disclaim any liability for any loss or damage that may result from any such suspension or postponement.

Shareholders Do Not Have the Protections Associated With Ownership of Shares in an Investment Company Registered Under the Investment Company Act of 1940.

None of the Funds is not registered as an investment company under the Investment Company Act of 1940, as amended. Consequently, Shareholders do not have the legal and regulatory protections provided to the investors in investment companies that are registered as such.

Various Actual and Potential Conflicts of Interest May Be Detrimental to Shareholders.

Each Fund is subject to actual and potential conflicts of interest involving the Managing Owner or any of its affiliates, the Commodity Broker, including its principals and its affiliates, the Index

Sponsor and Marketing Agent, and Invesco Distributors. 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 Funds, which also presents the potential for numerous conflicts of interest with the Funds. The Managing Owner and its principals and affiliates are engaged in a broad array of asset management and financial services activities and may engage in activities during the ordinary course of business that cause their interests or those of their other clients to conflict with those of the Funds and their Shareholders.

As a result of these and other relationships, parties involved with the Funds have a financial incentive to act in a manner other than in the best interests of the Funds and the Shareholders. For example, by investing in affiliated money market mutual funds and/orT-Bill ETFs for margin and/or cash management purposes, the Managing Owner may select affiliated money market mutual funds and/orT-Bill ETFs that may pay dividends that are lower thannon-affiliated money market mutual funds and/orT-Bill ETFs. In addition, the Managing Owner would have a conflict of interest if it sought to redeem a Fund’s interest in an affiliated money market mutual fund orT-Bill ETF in circumstances where such a redemption would be unfavorable for the affiliated fund. 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 Funds and the Shareholders.

The Funds 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.

Because the Managing Owner and Invesco Distributors are affiliates, the Managing Owner has a disincentive to replace Invesco Distributors. Furthermore, the Managing Owner did not conduct an arm’s length negotiation when it retained Invesco Distributors.

Lack of Independent Advisers Representing Investors.

The Managing Owner has consulted with counsel, accountants and other advisers regarding the operation of the Funds. No counsel has been appointed to represent you in connection with the Funds’ continuous offering of Shares. Accordingly, you should consult your own legal, tax and financial advisers about whether you should invest in the Shares.

Possibility of Termination of the Funds May Adversely Affect Your Portfolio.

It is ultimately within the discretion of the Managing Owner whether it will continue to operate and advise each Fund. The Managing Owner may withdraw from any of the Funds upon 120 days’ prior written notice to all Limited Owners and the Trustee, which would cause any such Fund to terminate unless a substitute managing owner was obtained. Limited Owners of 50% of the Shares have the power to terminate any of the Funds. If it is so exercised, investors who may wish to continue to invest in a vehicle that tracks the Funds’ Indexes will have to find another vehicle, and may not be able to find another vehicle that offers the same features as the relevant Fund. See “Description of the Shares; Certain Material Terms of the Trust Agreement – 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 Funds.

Shareholders Do Not Have the Rights Enjoyed by Investors in Certain Other Vehicles.

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. However, under Delaware law, a beneficial owner of a business trust (such as a Shareholder) may, under certain circumstances, institute legal action on behalf of himself and all other similarly situated beneficial owners to recover damages from a third party where a managing owner

has failed or refused to institute legal action on behalf of himself and all other similarly situated beneficial owners to recover damages from a managing owner for violations of fiduciary duties, or on behalf of a business trust to recover damages from a third party where a managing owner has failed or refused to institute proceedings to recover such damages. The Shares have limited voting and distribution rights (for example, Shareholders do not have the right to elect directors and the Funds are not required to pay regular distributions, although the Funds may pay distributions in the discretion of the Managing Owner).

Competing Claims Over Ownership of Intellectual Property Rights Related to the Funds Could Adversely Affect the Funds and an Investment in the Shares.

While the Managing Owner believes that all intellectual property rights needed to operate the Funds in the manner described in this Prospectus 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 Funds. To the extent any claims of such ownership are brought or any proceedings are instituted to assert such claims, the issuance of any restraining orders or injunctions, the negotiation, litigation or settlement of such claims, or the ultimate disposition of such claims in a court of law may adversely affect the Funds and an investment in the Shares. For example, such actions could result in expenses or damages payable by the Funds, suspension of activities or the termination of the Funds.

The Value of the Shares Will be Adversely Affected if the Funds is Required to Indemnify the Trustee or the Managing Owner.

Under the Trust Agreement, the Trustee and the Managing Owner have the right to be indemnified for any liability or expense they incur, except for any expenses resulting from gross negligence or willful misconduct. That means the Managing Owner may require the assets of any of the Funds 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 NAV of the Fund and, consequently, the value of the Shares.

Although the Shares are Limited Liability Investments, Certain Circumstances such as Bankruptcy of the Funds or Indemnification of the Funds by the Shareholders will Increase a Shareholder’s Liability.

The Shares are limited liability investments; investors may not lose more than the amount that they invest plus any appreciation in their investments. However, Shareholders could be required, as a matter of bankruptcy law, to return to the estate of a Fund any distribution they received at a time when the Fund was in fact insolvent or in violation of its Trust Agreement. In addition, Shareholders agree in the Trust Agreement that they will indemnify each Fund for any harm suffered by it as a result of:

•

Shareholders’ actions unrelated to the business of the Fund, or

•

taxes imposed on the Shares by the states or municipalities in which such investors reside.

The Funds may Potentially Lose Money on their Holdings of Money Market Mutual Funds.

The Funds may invest in government money market funds that have chosen to not rely on the ability to impose fees on shareholder redemptions (“liquidity fees”) or temporarily to suspend redemption privileges (“gates”) if the government money market fund’s weekly liquid assets fall below a certain threshold. Although such government money market funds seek to preserve the value of an investment at $1.00 per share, there is no guarantee that they will be able to do so and the Funds may lose money by investing in a government money market fund. An investment in a government money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. The share price of a government money market fund can fall below the $1.00 share price. The Funds cannot rely on or expect a government money market fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the government money market fund’s $1.00 share price. The credit quality of a government money market fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the government money market fund’s share price. Due to fluctuations in interest rates, the market value of

securities held by a government money market fund may vary. A government money market fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets.

Due to the Increased use of Technologies, Intentional and Unintentional Cyber Attacks Pose Operational and Information Security Risks.

With the increased use of technologies such as the Internet and the dependence on computer systems to perform necessary business functions, the Funds are susceptible to operational and information security risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber attacks include, but are not limited to gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causingdenial-of-service attacks on websites. Cyber security failures or breaches of the Funds’ third party service providers (including, but not limited to, Index Sponsor, the Administrator and transfer agent) or the issuers of the money market mutual funds andT-Bill ETFs in which the Funds invest, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. The Funds and its shareholders could be negatively impacted as a result. While the Managing Owner has established business continuity plans and systems to prevent such cyber attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Funds cannot control the cyber security plans and systems put in place by the Funds’ third party service providers. Cyber attacks may also cause disruptions to the futures exchanges and clearinghouses through which the Funds invest in exchange-traded futures contracts, resulting in disruptions to the Funds’ investment objectives and resulting in financial losses.

FORWARD-LOOKING STATEMENTS

This Prospectus includes forward-looking statements that reflect the Managing Owner’s current expectations about the future results, performance, prospects and opportunities of the Fund. The Managing Owner has tried to identify these forward-looking statements by using words such as “may,” “will,” “expect,” “anticipate,” “believe,” “intend,” “should,” “estimate” or the negative of those terms or similar expressions. These forward-looking statements are based on information currently available to the Managing Owner and are subject to a number of risks, uncertainties and other factors, both known, such as those described in “Risk Factors” and elsewhere in this Prospectus, and unknown, that could cause the actual results, performance, prospects or opportunities of the Fund to differ materially from those expressed in, or implied by, these forward-looking statements.

You should not place undue reliance on any forward-looking statements. Except as expressly required by the federal securities laws, the Managing Owner undertakes no obligation to publicly update or revise any forward-looking statements or the risks, uncertainties or other factors described in this Prospectus, as a result of new information, future events or changed circumstances or for any other reason after the date of this Prospectus.

INVESTMENT OBJECTIVES OF THE FUNDS

Each Fund seeks to track changes, whether positive or negative, in the level of its corresponding Index over time, plus the excess, if any, of the sum of its Treasury Income, Money Market Income andT-Bill ETF Income over its expenses. Each Fund invests in futures contracts in an attempt to track its corresponding Index. Each Fund holds Treasury Securities, money market mutual funds andT-Bill ETFs for margin and/or cash management purposes only and each Fund’s performance reflects the appreciation or depreciation of such securities.

The Shares of each Fund are designed for investors who want a cost-effective and convenient way to invest in commodity futures on U.S. andnon-U.S. markets.

Advantages of investing in the Funds include:

•

Margin. Shares are eligible for margin accounts.

•

Diversification. The Shares may help to diversify a portfolio of other investments, because historically the Indexes have tended to exhibit low to negative correlation with both equities and conventional bonds and positive correlation to inflation.

•

Optimum Yield™. The Indexes utilize an Optimum Yield™ methodology, which seeks to minimize the effects of negative roll yield that may be experienced by conventional commodities indexes.

•

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

Each Fund’s Shares are intended to provide investment results that generally correspond to the changes, positive or negative, in the levels of the corresponding Index over time. The value of each Fund’s Shares is expected to fluctuate in relation to changes in the value of its portfolio. The market price of a Fund’s Shares may not be identical to the NAV per Share, but these two valuations are expected to be very close. See “Risk Factors – NAV 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.”

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

The Funds being offered pursuant to this Prospectus intend to reflect the below sectors:

PowerShares DB Energy Fund is designed to track the DBIQ Optimum Yield Energy Index Excess Return™(DBIQ-OY Energy ER™), which is intended to reflect the energy sector.

PowerShares DB Oil Fund is designed to track the DBIQ Optimum Yield Crude Oil Index Excess Return™(DBIQ-OY CL ER™), which is intended to reflect the changes in market value of the crude oil sector.

PowerShares DB Gold Fund is designed to track the DBIQ Optimum Yield Gold Index Excess Return™(DBIQ-OY GC ER™), which is intended to reflect the changes in market value of the gold sector.

PowerShares DB Base Metals Fund is designed to track the DBIQ Optimum Yield Industrial Metals Index Excess Return™(DBIQ-OY Industrial Metals ER™), which is intended to reflect the base metals sector.

Each Fund trades Index Contracts that are subject to position limits under regulations of the CFTC or futures exchange rules, as applicable. The Managing Owner may determine to invest in other futures contracts if at any time it is impractical or inefficient to gain full or partial exposure to an Index Commodity through the use of Index Contracts. These other futures contracts may or may not be based on an Index Commodity. When they are not, the Managing Owner seeks to select futures contracts that it reasonably believes tend to exhibit trading prices that correlate with an Index Contract.

As a Fund that is designed to track an Index with more than one underlying commodity approaches or reaches position limits with respect to

an Index Commodity, the Fund may commence investing in Index Contracts that reference other Index Commodities. In those circumstances, the Fund may also trade in futures contracts based on commodities other than Index Commodities that the Managing Owner reasonably believes tend to exhibit trading prices that correlate with an Index Contract. As a Fund that is designed to track an Index with one underlying commodity approaches or reaches position limits with respect to an Index Commodity, the Fund may commence investing in futures contracts based on commodities other than the Index Commodity that the Managing Owner reasonably believes tend to exhibit trading prices that correlate with an Index Contract.

Under the Trust Agreement, the Managing Owner has exclusive management and control of all aspects of the business of the Funds. The Trustee’s duties and liabilities with respect to the offering of the Shares and the management of the Funds are limited to its express obligations under the Trust Agreement. 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.

There can be no assurance that any of the Funds 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 each Fund.

Specifically, with respect to each Fund, the Managing Owner:

•

selects the Trustee, Commodity Broker, Administrator, Index Sponsor, Custodian, Transfer Agent, Marketing Agent, distributor and auditor;

•

negotiates various agreements and fees;

•

performs such other services as the Managing Owner believes that each Fund may from time to time require; and

•

monitors the performance results of each Fund’s portfolio and reallocates assets

within such portfolio with a view to causing the performance of each Fund’s portfolio to track its corresponding Index over time.

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 Managing Owner is anNFA-approved swap firm.

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.

BREAKEVEN ANALYSIS

The estimated amount of all fees and expenses which are anticipated to be incurred by a new investor in Shares during the first twelve months of investment is 0.78% per annum of the NAV of the PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund, or $0.20 per annum per Share at $25.00, including the amount of any commissions charged by the investor’s broker. The estimated amount of all fees and expenses which are anticipated to be incurred by a new investor in Shares during the first twelve months of investment is 0.80% per annum of the NAV of the PowerShares DB Base Metals Fund, or $0.20 per annum per Share at $25.00, including the amount of any commissions charged by the investor’s broker.

Each Fund, except with respect to the PowerShares DB Base Metals Fund, will be successful only if its annual returns from futures trading, plus its annual Treasury Income, Money Market Income andT-Bill ETF Income exceed such fees and expenses of approximately 0.78% per annum. The PowerShares DB Base Metals Fund will be successful only if its annual returns from futures trading, plus its annual Treasury Income, Money Market Income andT-Bill ETF Income exceed such fees and expenses of approximately 0.80% per annum. Each Fund is expected to earn Treasury Income equal to 1.32% per annum, based upon the yield of3-month United States Treasury Securities as of December 29, 2017, or a maximum of $0.33 per annum per Share at $25.00 as the NAV per Share.

Each Fund is also expected to earn Money Market Income equal to 1.18% per annum as of December 29, 2017, or a maximum of $0.30 per annum per Share at $25.00 as the NAV per Share. Each Fund is also expected to earnT-Bill ETF Income equal to 1.40% per annum as of December 29, 2017, or a maximum of $0.35 per annum per Share at $25.00 as the NAV per Share. Because each Fund invests a portion of its assets in Treasury Securities, the money market mutual funds andT-Bill ETFs, its expected income from each of its holdings will be approximately $0.25, $0.01 and $0.07, respectively, for an aggregate amount of approximately $0.33 per Share at $25.00 as the NAV per Share. Therefore, based upon the difference between the sum of the Treasury Income plus the Money Market Income plus theT-Bill ETF Income, on the one hand, and the annual fees and expenses, on the other hand, the PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund will break-even on an investment during the first twelve months of an investment, unless the Fund loses at least approximately 0.55% per annum, or $0.13 per annum per Share at $25.00 as the NAV per Share. The PowerShares DB Base Metals Fund will break-even on an investment during the first twelve months of an investment, unless the Fund loses at least approximately 0.53% per annum, or $0.12 per annum per Share at $25.00 as the NAV per Share.

Breakeven Table

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

[Remainder of page left blank intentionally.]

BREAKEVEN TABLE

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

The breakeven analysis set forth in this table assumes that the Shares have a constantmonth-end NAV per Share of $25.00. The initial offering price of the Shares was $25 per Share, which has been consistently used for the breakeven analysis. Using the same NAV per Share enables investors and potential investors to compare on a consistent basis the breakeven point of each Fund with the other commodity futures-based ETFs operated by the Managing Owner. The Managing Owner, in its discretion, may change the assumed NAV per Share in the future. See the “Charges” section for an explanation of the expenses included in the Breakeven Table. The Managing Owner will pay a marketing services fee to the Marketing Agent and an index services fee to the Index Sponsor. Because the marketing services fee and the index services fee are not paid by the Funds, these fees are not included in the breakeven analysis.

From the Management Fee, the Managing Owner is responsible for paying the fees and expenses of the Administrator, Invesco Distributors, the Index Sponsor and the Marketing Agent.

Each Fund may, for margin and/or cash management purposes, invest in money market mutual funds and/orT-Bill ETFs that are managed by affiliates of the Managing Owner. The indirect portion of the management fees that such Fund may incur through such investments is in addition to the Management Fee paid to the Managing Owner. The Managing Owner has contractually agreed to waive the fees that it receives in an amount equal to the indirect management fees that each Fund incurs through its investments in affiliated money market mutual funds and/or affiliatedT-Bill ETFs indefinitely.

As of the date of this prospectus, this waiver is approximately less than $0.01 per Share per annum for each of the Funds.

The actual amount of brokerage commissions and trading fees to be incurred will vary based upon the trading frequency of each Fund and the specific futures contracts traded.

The Managing Owner is responsible for paying all routine operational, administrative and other ordinary expenses of each Fund.

Authorized Participants pay a transaction fee in the amount of $500 per order to create and redeem Baskets. Because these transaction fees arede minimis in amount, are charged on atransaction-by-transaction basis (and not on aBasket-by-Basket basis), and are borne by the Authorized Participants, they have not been included in the Breakeven Table.

Interest income currently is estimated to be earned at a rate of 1.32%, based upon the yield on3-month United States Treasury Securities as of December 29, 2017, or the Treasury Income. Dividend income currently is estimated to be earned at a rate of 1.18% from the Fund’s holdings of money market mutual funds (affiliated or otherwise) as of December 29, 2017, or the Money Market Income. The dollar amount shown is based on the relative amounts of these income producing instruments held by the Fund. Dividend income currently is estimated to be earned at a rate of 1.40% from the Fund’s holdings ofT-Bill ETFs (affiliates or otherwise) as of December 29, 2017, or theT-Bill ETF Income. Actual Treasury Income, Money Market Income andT-Bill ETF Income could be higher or lower than the levels shown.

The table indicates that the breakeven amount during the first 12 months of an investment in each Fund is $0.00 and 0% of NAV. These figures reflect that, during those first 12 months, each Fund’s Treasury Income, Money Market Income, andT-Bill ETF Income are expected to exceed the Fund’s fees and expenses. As disclosed earlier in the Funds’ breakeven analysis, each of the PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund will break even unless it loses at least approximately 0.55% per annum, or $0.13 per annum per Share at $25.00 as the NAV per Share. The PowerShares DB Base Metals Fund will break even unless it loses at least approximately 0.53% per annum, or $0.12 per annum per Share at $25.00 as the NAV per Share.

You may pay brokerage commissions in connection with purchases of the Shares. Because such brokerage commission rates are set by your broker, they will vary from investor to investor and have not been included in the Breakeven Table. Investors are encouraged to review the terms of their brokerage accounts for applicable charges.

Footnotes to Performance Information

1. “Aggregate Gross Capital Subscriptions” is the aggregate of all amounts ever contributed to the relevant pool, including investors who subsequently redeemed their investments.

2. “NAV” is the NAV of the relevant pool as of Friday, December 29, 2017. As December 31, 2017 was a Sunday, the Funds did not engage in any trading or creation or redemption of Shares on that date.

3. “NAV per Share” is the NAV of the relevant pool divided by the total number of Shares outstanding with respect to such pool as of December 29, 2017.

4. “Worst Monthly Drawdown” is the largest single month loss sustained during the most recent five calendar years and year to date (if applicable). “Drawdown” as used in this section of the Prospectus means losses experienced by the relevant pool over the specified period and is calculated on a rate of return basis, i.e., dividing net performance by beginning equity. “Drawdown” is measured on the basis of monthly returns only, and does not reflect intra-month figures. “Month” is the month of the Worst Monthly Drawdown.

5. “WorstPeak-to-Valley Drawdown” is the largest percentage decline in the NAV per Share during the last five years (and to the extent applicable, for a period beyond the most recent five calendar years if the starting date of the peak value extends beyond this period). This need not be a continuous decline, but can be a series of positive and negative returns where the negative returns are larger than the positive returns. “WorstPeak-to-Valley Drawdown” represents the greatest percentage decline from anymonth-end NAV per Share that occurs without suchmonth-end NAV per Share being equaled or exceeded as of a subsequentmonth-end. For example, if the NAV per Share of a particular pool declined by $1 in each of January and February, increased by $1 in March and declined again by $2 in April, a“peak-to-valley drawdown” analysis conducted as of the end of April would consider that “drawdown” to be still continuing and to be $3 in amount, whereas if the NAV per Share had increased by $2 in March, the January-February drawdown would have ended as of the end of February at the $2 level.

6. “Compound Rate of Return” of the relevant pool is calculated by multiplying on a compound basis each of the monthly rates of return set forth in the respective charts above and not by adding or averaging such monthly rates of return. For periods of less than one year, the results areyear-to-date.

General

Each of the DBIQ-OYER™ and the DBIQ ER™ is intended to reflect the changes in market value, over time, positive or negative, in certain sectors of commodities. Each Index is calculated on an excess return, or unfunded, basis. All Indexes corresponding to the Funds, are rolled in a manner

which is aimed at potentially maximizing the roll benefits in backwardated markets and minimizing the losses from rolling in contangoed markets. Each Index is comprised of one or more Index Commodities. The composition of Index Commodities with respect to each Index varies according to each specific sector that such Index intends to reflect. Each Index Commodity is assigned an Index Base Weight, which is intended to reflect the proportion of such Index Commodity relative to each Index.

Indexes and Covered Sectors

The Indexes track the following sectors:

•

DBIQ Optimum Yield Energy Index Excess Return™(“DBIQ-OY Energy ER™”) is intended to reflect the energy sector.

•

DBIQ Optimum Yield Crude Oil Index Excess Return™(“DBIQ-OY CL ER™”) is intended to reflect the changes in market value of the crude oil sector.

•

DBIQ Optimum Yield Precious Metals Index Excess Return™(“DBIQ-OY Precious Metals ER™”) is intended to reflect the precious metals sector.

•

DBIQ Optimum Yield Gold Index Excess Return™(“DBIQ-OY GC ER™”) is intended to reflect the changes in market value of the gold sector.

•

DBIQ Optimum Yield Industrial Metals Index Excess Return™(“DBIQ-OY Industrial Metals ER™”) is intended to reflect the base metals sector.

DBIQ-OY CL ER™ andDBIQ-OY GC ER™ are Indexes with a single Index Commodity (“Single Commodity Sector Indexes”).

Each Index has been calculated back to the Base Date. On the Base Date the Closing Level of each Index was 100.

The Index Sponsor is Deutsche Bank Securities Inc. 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.

Legend:

“COMEX” means the Commodity Exchange Inc., New York, a part of the CME Group, or its successor.

“ICE-UK” means ICE Futures Europe, or its successor.

“LME” means The London Metal Exchange Limited, or its successor.

“NYMEX” means the New York Mercantile Exchange, a part of the CME Group, or its successor.

Composition of Indexes

With the exception of the Single Commodity Sector Indexes, each Index is composed of notional amounts of each of the underlying Index Commodities. Each Single Commodity Sector Index is composed of one underlying Index Commodity. The notional amounts of the Index Commodities included in each multi-sector Index are intended to reflect the changes in market value of each such Index Commodity within the specific Index.

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

Each 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, each Fund employs a rule-based approach when it ‘rolls’ from one futures contract to another. Rather than select a new futures contract based on a predetermined schedule (e.g., monthly), each Index Commodity is rolled from one contract to another futures contract that is intended to generate the most favorable “implied roll yield” under prevailing market conditions. When there is an upward-sloping price curve for futures contracts, the implied roll yield is expected to be negative. The selection of a new futures contract on an Index Commodity in such market conditions is designed to minimize the impact of negative roll yield. Conversely, where there is a downward-sloping price curve for futures contracts, the implied roll yield is expected to be positive. The selection of a new futures contract on an Index Commodity in such market conditions is designed to maximize the impact of positive roll yield. The OY Single Commodity Indexes take the impact of implied roll yield into consideration by selecting, as the replacement for an expiring futures contract, the futures contract with a delivery month within the next thirteen months that generates the most favorable implied roll yield under the current market conditions.

The market condition in which each relevant Index is designed to maximize the effect of positive roll yield when entering into new futures contracts is called backwardation. Rolling in a backwardated market will tend to enhance returns from futures trading. The market condition in which the Index is designed to mitigate the effect of negative roll yield when entering into new futures contracts is called contango. Rolling in a contangoed market will tend to cause a drag on returns from futures trading.

Returns from futures trading are called excess return, which is the combined return based on the spot prices of Index Commodities and the roll yield from trading futures contracts on Index Commodities.

The Managing Owner may determine to invest in other futures contracts if at any time it is impractical or inefficient to gain full or partial exposure to an Index Commodity through the use of Index Contracts or other futures contracts. These other futures contracts may or may not be based on an Index Commodity. When they are not, the Managing Owner may seek to select futures contracts that it reasonably believes tend to exhibit trading prices that correlate with an Index Contract. As a Fund that is designed to track an Index with more than one underlying commodity approaches or reaches position limits with respect to an Index Commodity, the Fund may commence investing in Index Contracts that reference other Index Commodities. In those circumstances, the Fund may also trade in futures contracts based on commodities other than Index Commodities that the Managing Owner reasonably believes tend to exhibit trading prices that correlate with an Index Contract. As a Fund that is designed to track an Index with one underlying commodity approaches or reaches position limits with respect to an Index Commodity, the Fund may commence investing in futures contracts based on commodities other than the Index Commodity that the Managing Owner reasonably believes tend to exhibit trading prices that correlate with an Index Contract.

Each Index is calculated in USD on an excess return (unfunded) basis, which means that the Index reflects the return associated with spot prices for Index Commodities and the roll yield associated with trading futures contracts on Index Commodities. Each Fund also invests in securities that are expected

to generate income, including Treasury Securities, money market mutual funds, andT-Bill ETFs. These securities are held with the Custodian. In addition, Treasury Securities for deposit may be held with the Commodity Broker as margin for a Fund’s futures positions. The Index does not reflect any corresponding income characteristics.

The futures contract price for each Index Commodity will be the exchange closing price for such Index Commodity on a day on which the relevant exchange is open for business (“Index Business Day”). 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 Verification Date, 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 Index Business Day is May 1 of the current year, and the Delivery Month of the Index Commodity futures contract currently in such OY Single Commodity Index is June of the current year, a new Index Commodity futures contract with a later Delivery Month will be selected.

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 thirteenth month after the Verification Date. For example, if the first Index Business Day is May 1 of the current year and the Delivery Month of an Index Commodity futures contract currently in an OY Single Commodity Index is therefore June of the current year, the Delivery Month of an eligible new Index Commodity futures contract must be between July of the current year and June of the following year. The implied roll yield is then calculated and the futures contract on the Index Commodity with the best possible implied roll yield under the current market conditions 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.

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

With the exception of the Single Commodity Sector Indexes, each Index isre-weighted on an annual basis on the sixth Index Business Day of each November.

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

Change in the Methodology of an Index

The Index Sponsor employs the methodology described above and its application of such methodology shall be conclusive and binding. While the Index Sponsor currently employs the above described methodology to calculate each Index, no assurance can be given that fiscal, market, regulatory,

juridical or financial circumstances (including, but not limited to, any changes to or any suspension or termination of or any other events affecting any Index Commodity or a futures contract) will not arise that would, in the view of the Index Sponsor, necessitate a modification of or change to such methodology. In such circumstances, the Index Sponsor may make any such modification or change as it determines appropriate. The Index Sponsor may also make adjustments to the terms of an Index in any manner that it may deem necessary or desirable, including (without limitation) to correct any manifest or proven error or to cure, correct or supplement any defective provision of an Index. The Index Sponsor will publish notice of any such adjustment and the effective date thereof as set forth below.

Publication of Closing Levels and Adjustments

In order to calculate each indicative Index level, the Index Sponsor polls Reuters every 15 seconds to determine the real time price of each underlying futures contract with respect to each Index Commodity of the applicable Index. The Index Sponsor then applies a set of rules to these values to create the indicative level of each Index. These rules are consistent with the rules which the Index Sponsor applies at the end of each trading day to calculate the closing level of each Index.

The IIV per Share of each Fund is based on the prior day’s final NAV, 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 NAV per Share.

The Index Sponsor calculates and publishes the closing level of each Index daily. The Managing Owner publishes the NAV of each Fund and the NAV per Share of each Fund daily. The Index Sponsor also calculates and publishes theintra-day Index level, and the Index Sponsor calculates, and the Managing Owner publishes, the IIV per Share of each Fund (quoted in U.S. dollars) once every fifteen seconds throughout each trading day.

All of the foregoing information is published as follows:

The current trading price per Share of each Fund (quoted in U.S. dollars) will be published

continuously under its ticker symbol as trades occur throughout each trading day on the consolidated tape, Reuters and/or Bloomberg and on the Managing Owner’s website athttp://www.powershares.com, or any successor thereto.

Interruption of Index Calculation

Calculation of each Index may not be possible or feasible under certain events or circumstances, including, without limitation, a systems failure, natural orman-made disaster, act of God, armed conflict, act of terrorism, riot or labor disruption or any similar intervening circumstance, that is beyond the reasonable control of the Index Sponsor and that the Index Sponsor determines affects an Index or any Index Commodity. Upon the occurrence of such force majeure events, the Index Sponsor may, in its discretion, elect one (or more) of the following options:

•

make such determinations and/or adjustments to the terms of such Index as it considers appropriate to determine any closing level on any such appropriate Index Business Day; and/or

•

defer publication of the information relating to such Index until the next Index Business Day on which it determines that no force majeure event exists; and/or

•

permanently cancel publication of the information relating to such Index.

Calculation of an Index may also be disrupted by an event that would require the Index

Sponsor to calculate the closing price in respect of the relevant Index Commodity on an alternative basis were such event to occur or exist on a day that is a trading day for futures contracts in such Index Commodity on the relevant exchange. If such an Index disruption event occurs and continues for a period of five successive trading days, the Index Sponsor will, in its discretion, either:

•

continue to calculate the relevant closing price for a further period of five successive trading days for such Index Commodity on the relevant exchange; or

•

if such period extends beyond the five successive trading days, the Index Sponsor may elect to replace the futures contract with respect to a specific Index Commodity and shall make all necessary adjustments to the methodology and calculation of an Index as it deems appropriate.

Historical Closing Levels

The Closing Level Tables present Closing Levels since January 2008.

The historic data shown with respect to the closing prices of futures contracts on Light, Sweet Crude Oil (CL), Heating Oil (HO), Gold (GC), Aluminum (MAL), Brent Crude Oil (LCO), RBOB Gasoline (XB), Natural Gas (NG), Silver (SI), Zinc (MZN), and Copper – Grade A (MCU) originated from Reuters. The Index Sponsor has not independently verified the information extracted from this source.

Complete price histories regarding certain futures contracts on the Index Commodities were not available (e.g., due to lack of trading on specific days). In the event that prices on such futures contracts on the Index Commodities were unavailable during a contract selection day, such futures contracts were excluded from the futures contract selection process. The Index Sponsor believes that the incomplete price histories should not have a material impact on the calculation of any of the Indexes.

Each Index Closing Level is equal to the weighted sum of the market value of the commodity futures contracts of all the respective Index Commodities that comprise each specific Index. The market value of the commodity futures contracts of

an Index Commodity is equal to the number of commodity futures contracts multiplied by the commodity futures contracts’ closing price. The weight of an Index Commodity is the market value of the commodity futures contracts of the Index Commodity divided by the sum of all market values of all commodity futures contracts of the Index Commodities that comprise an Index multiplied by 100%.

The Index rules stipulate the holding in each Index Commodity futures contract. Holdings in each Index Commodity change during the Index rebalancing periods as determined by the Optimum Yield^TM roll rules.

Cautionary Statement-Statistical Information

Various statistical information is presented on the following pages, relating to the Closing Levels of each Index, on an annual and cumulative basis, including certain comparisons of each Index to other commodities indices. In reviewing such information, you should consider that:

•

See “Risk Factors – Price Volatility May Cause the Total Loss of Your Investment.”

•

The Closing Levels of each Index do not reflect any reduction commensurate with the fees, expenses, and other costs incurred by a Fund in connection with pursuant the Fund’s investment objective.

The Indexes were established in betweenMay-July 2006, as applicable, and are independently calculated by the Index Sponsor. The calculation methodology and commodity futures contract selection for the Indexes has been the same since the Indexes were established inMay-July 2006, as applicable, meaning that the same calculation method and contract selection have been used since the Base Date. Accordingly, the Closing Levels of each Index, terms of each Index methodology and Index Commodities, reflect an element of hindsight based on the calculations and selections made at the time each Index was established. See “Risk Factors – Historical Performance of the Fund and the Index is Not Indicative of Future Performance” and “Risk

Factors – Fewer Representative Commodities May Result in Greater Index Volatility.”

Information on the Indexes’ components and their performance over time is included below.

The Index Sponsor also maintains a separate index, DBIQ Optimum Yield Industrial Metals Index Total Return (“DBIQ Optimum Yield Industrial Metals TR™”) which the Fund does not track. DBIQ Optimum Yield Industrial Metals TR™ is calculated on a funded (total return) basis, which reflects the change in market value of the underlying index commodities and interest income from a hypothetical basket of fixed income securities. DBIQ Optimum Yield Industrial Metals TR™ is included so that investors can evaluate an index with both futures and income components, as the particular Fund tracks the Index and expects to generate income from positions in Treasury Securities, money market funds, and/orT-Bill ETFs that are maintained for margin and/or cash management purposes.

NOTES:

1. “High” reflects the highest closing level of the Index during the applicable year.

2. “Low” reflects the lowest closing level of the Index during the applicable year.

3. “Annual Index Changes” reflect the change to the Index level on an annual basis as of December 31 of each applicable year.

4. “Index Changes Since Inception” reflects the change of the Index level since inception on a compounded annual basis as of December 31 of each applicable year.

5. Closing levels as of December 31, 2017.

6. “Annualized Changes to Index Level” reflect the change to the applicable index level on an annual basis as of December 31 of each applicable year.

7. “Average rolling 3 month daily volatility.” The daily volatility reflects the relative rate at which the price of the applicable index moves up and down, which is found by calculating the annualized standard deviation of the daily change in price. In turn, an average of this value is calculated on a 3 month rolling basis.

8. “Sharpe Ratio” compares the annualized rate of return minus the annualized risk-free rate of return to the annualized variability – often referred to as the “standard deviation” – of the monthly rates of return. A Sharpe Ratio of 1:1 or higher indicates that, according to the measures used in calculating the ratio, the rate of return achieved by a particular strategy has equaled or exceeded the risks assumed by such strategy. The risk-free rates of return that were used in these calculations for the indexes with respect to the PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund, PowerShares DB Gold Fund and PowerShares DB Base Metals Fund were assumed to be 2.78%, 3.06%, 3.06%, 3.06% and 2.02%, respectively.

9. “% of months with positive change” during the period from inception to December 31, 2017.

10. “Average monthly positive change” during the period from inception to December 31, 2017.

11. “Average monthly negative change” during the period from inception to December 31, 2017.

12. “Annualized Index Levels” reflect the change to the level of the applicable index on an annual basis as of December 31 of each applicable time period (e.g., one year, three, five or seven years, as applicable).

USE OF PROCEEDS

Proceeds of the offering of the Shares of each Fund are used by each Fund to engage in the trading of futures on its Index Commodities with a view to tracking the changes, positive or negative, in the level of its Index over time. Proceeds of each Fund’s offering are also used to pay the Fund’s fees, expenses, and other costs. Each Fund’s portfolio also includes United States Treasury Securities for deposit with such Fund’s Commodity Broker as margin and United States Treasury Securities, cash and money market mutual funds (affiliated or otherwise) on deposit with such Fund’s Custodian (for margin and/or cash management purposes). In addition, the Funds also gain an exposure to United States Treasury Securities with a maximum remaining maturity of up to twelve months through each Fund’s holdings ofT-Bill ETFs (affiliated or otherwise). Such holdings ofT-Bill ETFs are on deposit with such Fund’s Custodian (for margin and/or cash management purposes).

The following table reflects the approximate percentage of each Fund’s NAV that is required to be posted as collateral with respect to its holdings of each Fund’s applicable futures contracts as of December 31, 2017:


Fund		Approximate % of each Fund’s NAV posted as collateral for applicable futures contracts
DBE		3.40
DBO		3.34
DBP		3.25
DGL		2.83
DBB		6.56

Collateral requirements are initially set by the applicable futures exchanges. The Commodity Broker applies an additional collateral requirement based on a number of factors, including, but not limited to, volatility, concentration, percentage of open interest, and position size with respect to each Fund’s futures contracts. For purposes of calculating the approximate percentage of each Fund’s NAV that was posted as collateral, each Fund’s aggregate assets under management reflected the sum of each Fund’s holdings of Treasury Securities, money market mutual funds,T-Bill ETFs, cash and the value of the applicable futures contracts that have been marked to market as of December 31, 2017.

The changes in market value over time, whether positive or negative, of the futures contracts held by the PowerShares DB Energy Fund are intended to reflect the changes in the market value of the energy sector.

The changes in market value over time, whether positive or negative, of the futures contracts held by the PowerShares DB Oil Fund are intended to reflect the changes in market value of crude oil.

The changes in market value over time, whether positive or negative, of the futures contracts held by the PowerShares DB Precious Metals Fund are intended to reflect the changes in market value of the precious metals sector.

The changes in market value over time, whether positive or negative, of the futures contracts held by the PowerShares DB Gold Fund are intended to reflect the changes in market value of gold.

The changes in market value over time, whether positive or negative, of the futures contracts held by the PowerShares DB Base Metals Fund are intended to reflect the base metals sector.

To the extent that a Fund trades futures contracts on United States exchanges, the assets deposited by such Fund with its Commodity Broker as margin must be segregated pursuant to the regulations of the CFTC. Such segregated funds may be invested only in a limited range of instruments – principally U.S. government obligations.

The Funds may trade in futures contracts onnon-U.S. exchanges, for instance, if at any time it is impractical or inefficient to gain full or partial exposure to any Index Commodity through the use of Index Contracts. To the extent, if any, that a Fund trades futures on markets other than United States futures exchanges, funds deposited to margin positions held on such exchanges are invested in bank deposits or in instruments of a credit standing generally comparable to those authorized by the CFTC for investment of “customer segregated funds,” although applicable CFTC rules prohibit funds employed in trading on foreign exchanges from being deposited in “customer segregated fund accounts” (certain exceptions apply).

Although the percentages set forth below may vary substantially over time, as of the date of this Prospectus, each Fund estimates that:

(i)

approximately3%-7% of the NAV of each Fund will be required to be maintained in segregated accounts in the name of such Fund with the Commodity Broker (or another eligible financial institution, as applicable) in the form of cash, money market mutual funds orT-Bill ETFs (affiliated or otherwise) or United States Treasury Securities to margin positions of all commodities combined. Such funds are segregated pursuant to CFTC rules;

(ii)

approximately93%-97% of the NAV of each Fund is maintained in segregated accounts with the Custodian in the name of such Fund in bank deposits, money market mutual funds,T-Bill ETFs or United States Treasury Securities (or other securities approved by the CFTC for investment of customer funds) for margin and/or cash management purposes when assets of a Fund are not being used to margin positions.

The Managing Owner, a CFTC-registered commodity pool operator and commodity trading advisor is responsible for the cash management activities of each Fund, including investing in United States Treasury Securities, money market mutual funds (affiliated or otherwise) andT-Bill ETFs (affiliated or otherwise), as applicable.

Each Fund receives 100% of its Treasury Income, Money Market Income andT-Bill ETF Income.

CHARGES

See “Breakeven Analysis” for breakeven related information.

Management Fee

Each Fund pays the Managing Owner a Management Fee, monthly in arrears, in an amount equal to 0.75% per annum of the daily NAV of the Fund. The Management Fee is paid in consideration of the Managing Owner’s services related to the

management of each Fund’s business and affairs, including the provision of commodity futures trading advisory services.

Each Fund may, for margin and/or cash management purposes, invest in money market mutual funds and/orT-Bill ETFs that are managed by affiliates of the Managing Owner. The indirect portion of the management fees that such Fund may incur through such investments is in addition to the Management Fee paid to the Managing Owner. The Managing Owner has contractually agreed to waive the fees that it receives in an amount equal to the indirect management fees that each Fund incurs through its investments in affiliated money market mutual funds and/or affiliatedT-Bill ETFs indefinitely.

Organization and Offering Expenses

Expenses incurred in connection with organizing each Fund and the initial offering of each Fund’s Shares were paid by DB Commodity Services LLC (the “Predecessor Managing Owner”). Expenses incurred in connection with the continuous offering of Shares of each Fund from commencement of each Fund’s trading operations up to and excluding February 23, 2015 were also paid by the Predecessor Managing Owner. Expenses incurred in connection with the continuous offering of Shares of each Fund on and after February 23, 2015 are paid by the Managing Owner. The Managing Owner aggregates the offering expenses related to the Funds and other commodity pools within the PowerShares DB fund suite, and allocates the costs associated to each Fund for payment by the Managing Owner on behalf of each Fund. The Managing Owner expects that the expenses incurred in connection with the continuous offering of Shares of the PowerShares DB fund suite may be approximately 0.05% of the average of the funds’ NAV during the life of the Fund’s currently effective registration statement. These costs may vary 3considerably during the life of a Fund’s current registration statement, but the Managing Owner retains the obligation to pay those expenses in lieu of the Fund.

Offering expenses relating to a Fund means those expenses incurred in connection with offering, distributing and processing the Shares of such Fund under applicable federal law, and any other expenses actually incurred and, directly or indirectly, related to

the continuous offering of the Shares of such Fund, including, but not limited to, expenses such as:

•

registration fees, filing fees and taxes;

•

costs of preparing, printing (including typesetting), amending, supplementing, mailing and distributing the Registration Statement, the exhibits thereto and this Prospectus;

•

the costs of qualifying, printing (including typesetting), amending, supplementing, mailing and distributing sales materials used in connection with the offering and issuance of the Shares;

•

travel, telegraph, telephone and other expenses in connection with the offering and issuance of the Shares; and

•

accounting, auditing and legal fees (including disbursements related thereto) incurred in connection therewith.

The Managing Owner will not allocate to the Funds the indirect expenses of the Managing Owner.

Brokerage Commissions and Fees

Each 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 its trading activities. On average, total charges paid to the Commodity Broker are expected to be less than $6.00 per round-turn trade (except with respect to the PowerShares DB Base Metals Fund, which is expected to be less than $13.00 per round-turn trade), although the Commodity Broker’s brokerage commissions and trading fees are determined on acontract-by-contract, or round-turn, basis. A round-turn trade is a completed transaction involving both a purchase and a liquidating sale, or a sale followed by a covering purchase. The Managing Owner estimates the brokerage commissions and fees will be approximately (i) 0.03% of the NAV of each Fund with respect to PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund and PowerShares DB Gold Fund and (ii) 0.05% of the NAV with respect to PowerShares DB Base Metals 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.

Routine Operational, Administrative and Other Ordinary Expenses

The Managing Owner pays all routine operational, administrative and other ordinary expenses of each Fund, generally, as determined by the Managing Owner. These expenses include, but are not limited to, computer service expenses, the fees and expenses of the Trustee, license and service fees paid to DBSI as Marketing Agent and Index Sponsor, legal and accounting fees and expenses, tax preparation expenses, filing fees, and printing, mailing and duplication costs. Each Fund does not reimburse the Managing Owner for the routine operational, administrative and other ordinary expenses of each Fund. The Managing Owner aggregates the routine operational, administrative and other ordinary expenses related to the Funds and other commodity and currency pools within the PowerShares DB fund suite, and allocates the costs associated to each Fund. The expenses may vary, but the Managing Owner retains the obligation to pay those expenses in lieu of a Fund. The Managing Owner expects that all of the routine operational, administrative and other ordinary expenses of the PowerShares DB fund suite will be approximately 0.36% per annum of the average of the funds’ NAV.

Non-Recurring Fees and Expenses

Each Fund pays all itsnon-recurring and unusual fees and expenses (referred to as extraordinary fees and expenses in the Trust Agreement) of the Fund generally, if any, as determined by the Managing Owner.Non-recurring and unusual fees and expenses are fees and expenses which arenon-recurring and unusual in nature, such as legal claims and liabilities and litigation costs or indemnification or other unanticipated expenses.Non-recurring and unusual fees and expenses will also include material expenses which are not currently anticipated obligations of the Funds or of managed futures funds in general. Routine operational, administrative and other ordinary expenses will not be deemednon-recurring expenses.

Management Fee and Expenses to be Paid First out of Treasury Income, Money Market Income and/orT-Bill ETF Income

The Management Fee and the brokerage commissions and fees of each Fund are paid first out

of Treasury Income from such Fund’s holdings of United States Treasury Securities, Money Market Income from such Fund’s holdings of money market mutual funds (affiliated or otherwise) andT-Bill ETF Income from such Fund’s holdings ofT-Bill ETFs (affiliated or otherwise), as applicable, on deposit with the Commodity Broker as margin, the Custodian, or otherwise. If the sum of the Treasury Income, the Money Market Income and theT-Bill ETF Income, as applicable, is not sufficient to cover the fees and expenses of each Fund during any period, the excess of such fees and expenses over such Treasury Income, Money Market Income andT-Bill ETF Income, as applicable, will be paid out of income from futures trading, if any, or from sales of the Fund’s United States Treasury Securities and/or holdings in money market mutual funds and/or holdings inT-Bill ETFs. Each Fund invests in its futures contracts in an attempt to track its corresponding Index. Each Fund holds Treasury Securities, money market mutual funds andT-Bill ETFs for margin and/or cash management purposes only.

Selling Commission

Retail investors may purchase and sell Shares through traditional brokerage accounts. Investors are expected to be charged a commission by their brokers in connection with purchases of Shares that will vary from investor to investor. Investors are encouraged to review the terms of their brokerage accounts for applicable charges.

The offering of Baskets is being made in compliance with Conduct Rule 2310 of the Financial Industry Regulatory Authority (“FINRA”). The excess, if any, of the price at which an Authorized Participant sells a Share over the price paid by such Authorized Participant in connection with the creation of such Share in a Basket may be deemed to be underwriting compensation by the FINRA Corporate Financing Department.

WHO MAY SUBSCRIBE

transactions, (2) be a participant in DTC, and (3) have entered into a Participant Agreement with the Funds and the Managing Owner. 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.

CREATION AND REDEMPTION OF SHARES

Each 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 Funds to other investors.

Authorized Participants are the only persons that may place orders to create and redeem Baskets. Authorized Participants must be (1) registered broker-dealers or other securities market participants, such as banks and other financial institutions, which are not required to register as broker-dealers to engage in securities transactions, and (2) participants in DTC. To become an Authorized Participant, a person must enter into a Participant Agreement with the Funds and the Managing Owner. The Participant Agreement sets forth the procedures for the creation and redemption of Baskets and for the payment of cash required for such creations and redemptions. The Managing Owner may delegate its duties and obligations under the Participant Agreement to Invesco Distributors, the Administrator or the Transfer Agent without consent from any Shareholder or Authorized Participant. The Participant Agreement and the related procedures attached thereto may be amended by the Managing Owner without the consent of any Shareholder or Authorized Participant. To compensate the Transfer Agent for services in processing the creation and redemption of Baskets, an Authorized Participant is required to pay a transaction fee of $500 per order to create or redeem Baskets. Authorized Participants who purchase Baskets from a Fund receive no fees,

commissions or other form of compensation or inducement of any kind from either the Managing Owner or the Fund, and no such person has any obligation or responsibility to the Managing Owner or the Fund to effect any sale or resale of Shares.

Authorized Participants are cautioned that some of their activities may result in their being deemed participants in a distribution in a manner which would render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the Securities Act of 1933 (the “Securities Act”), as described in “Plan of Distribution.”

Authorized Participants may act for their own accounts or as agents for broker-dealers, custodians and other securities market participants that wish to create or redeem Baskets.

Persons interested in purchasing Baskets should contact the Managing Owner or the Administrator to obtain the contact information for the Authorized Participants. Shareholders who are not Authorized Participants will only be able to redeem their Shares through an Authorized Participant.

Under the Participant Agreements, the Managing Owner has agreed to indemnify the Authorized Participants and certain parties related to the Authorized Participants against certain liabilities as a result of:

•

any breach by the Managing Owner, the Trust, or any of their respective agents or employees, of any provision of the Participant Agreement, including any representations, warranties and covenants by any of them or the Trust therein or in the Officers’ Certificate (as defined in the Participant Agreement);

•

any failure on the part of the Managing Owner to perform any obligation of the Managing Owner set forth in the Participant Agreement;

•

any failure by the Managing Owner to comply with applicable laws and regulations in connection with the Participant Agreement, except that the Managing Owner will not be required to indemnify a Managing Owner Indemnified Party (as

defined in the Participant Agreement) to the extent that such failure was caused by the reasonable reliance on instructions given or representations made by one or more Managing Owner Indemnified Parties or the negligence or willful malfeasance of any Managing Owner Indemnified Party;

•

any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement of the Trust as originally filed with the SEC, or in any amendment thereof, or in any prospectus, or in any amendment thereof or supplement thereto, or arising out of or based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except those statements in the Registration Statement or the Prospectus based on information furnished in writing by or on behalf of the Authorized Participant expressly for use in the Registration Statement or the Prospectus.

As provided in the Participant Agreements, in the absence of gross negligence, bad faith or willful misconduct, neither the Managing Owner nor an Authorized Participant will be liable to each other or to any other person, including any party claiming by, through or on behalf of the Authorized Participant, for any losses, liabilities, damages, costs or expenses arising out of any mistake or error in data or other information provided to any of them by each other or any other person or out of any interruption or delay in the electronic means of communications used by them.

The following description of the procedures for the creation and redemption of Baskets is only a summary and an investor should refer to the relevant provisions of the Trust Agreement and the form of Participant Agreement for more detail. The Trust Agreement and the form of Participant Agreement are filed as exhibits to the registration statement of which this Prospectus is a part.

Creation Procedures

On any business day, an Authorized Participant may place an order with the Transfer Agent to create one or more Baskets. For purposes of processing both

creation and redemption orders, a “business day” means any day other than a day when banks in New York City are required or permitted to be closed. Creation orders must be placed by 10:00 a.m., Eastern time. The day on which the Transfer Agent receives a valid creation order is the creation order date. The day on which a creation order is settled is the creation order settlement date. As provided below, the creation order settlement date may occur up to two business days after the creation order date. By placing a creation order, and prior to delivery of such Baskets, an Authorized Participant’s DTC account is charged thenon-refundable transaction fee due for the creation order.

Baskets are issued on the creation order settlement date as of 2:45 p.m., Eastern time, on the business day immediately following the creation order date at the applicable NAV per Share as of the closing time of the NYSE Arca or the last to close of the exchanges on which its futures contracts are traded, whichever is later, on the creation order date, but only if the required payment has been timely received. Upon submission of a creation order, the Authorized Participant may request the Managing Owner to agree to a creation order settlement date up to two business days after the creation order date. By placing a creation order, and prior to receipt of the Baskets, an Authorized Participant’s DTC account is charged thenon-refundable transaction fee due for the creation order.

Determination of Required Payment

The total payment required to create each Basket is the NAV of 200,000 Shares of the applicable 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 creation order date.

Because orders to purchase Baskets must be placed by 10:00 a.m., Eastern time, but the total payment required to create a Basket will not be determined until 4:00 p.m., Eastern time, on the date the creation order is received, Authorized Participants will not know the total amount of the payment required to create a Basket at the time they submit the creation order for the Basket. A Fund’s NAV and the total amount of the payment required to create a Basket could rise or fall substantially between the time a creation order is submitted and the time the amount of the purchase price in respect thereof is determined.

Rejection of Creation Orders

The Managing Owner or the Transfer Agent may reject a creation order if:

•

The Managing Owner or the Transfer Agent determines that the creation order is not in proper form;

•

The Managing Owner believes that the acceptance or receipt of the creation order would have adverse tax consequences to any Fund or its Shareholders; or

•

Circumstances outside the control of the Managing Owner or the Transfer Agent make it, for all practical purposes, not feasible to process creations of Baskets.

The Managing Owner will not be liable for the rejection of any creation order.

A Fund also may not be able to create new Baskets at any time if there is an insufficient amount of Shares registered in this offering or if another legal or operational impediment to creating new Baskets arises.

Redemption Procedures

The procedures by which an Authorized Participant can redeem one or more Baskets mirror the procedures for the creation of Baskets. On any business day, an Authorized Participant may place an order with the Transfer Agent to redeem one or more Baskets. Redemption orders must be placed by 10:00 a.m., Eastern time. The day on which the Managing Owner receives a valid redemption order is the redemption order date. The day on which a redemption order is settled is the redemption order settlement date. As provided below, the redemption order settlement date may occur up to two business days after the redemption order date. The redemption procedures allow Authorized Participants to redeem Baskets. Individual Shareholders may not redeem directly from a Fund. Instead, individual Shareholders may only redeem Shares in an amount equal to one or more whole Baskets and only through an Authorized Participant.

By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through DTC’s book-entry system to the applicable Fund not later than the redemption order

settlement date as of 2:45 p.m., Eastern time, on the business day immediately following the redemption order date. Upon submission of a redemption order, the Authorized Participant may request the Managing Owner to agree to a redemption order settlement date up to two business days after the redemption order date. By placing a redemption order, and prior to receipt of the redemption proceeds, an Authorized Participant’s DTC account is charged thenon-refundable transaction fee due for the redemption order.

Determination of Redemption Proceeds

The redemption proceeds from a Fund consist of the cash redemption amount. The cash redemption amount is equal to the NAV of the number of Basket(s) of such Fund requested in the Authorized Participant’s redemption order as of the closing time of the NYSE Arca or the last to close of the exchanges on which such Fund’s futures contracts are traded, whichever is later, on the redemption order date. The Managing Owner will distribute the cash redemption amount at the redemption order settlement date as of 2:45 p.m., Eastern time, on the redemption order settlement date through DTC to the account of the Authorized Participant as recorded on DTC’s book-entry system.

Delivery of Redemption Proceeds

The redemption proceeds due from a Fund are delivered to the Authorized Participant at 2:45 p.m., Eastern time, on the redemption order settlement date if, by such time, the Fund’s DTC account has been credited with the Baskets to be redeemed. If the Fund’s DTC account has not been credited with all of the Baskets to be redeemed by such time, the redemption distribution is delivered to the extent of whole Baskets received. Any remainder of the redemption distribution is delivered on the next business day to the extent of remaining whole Baskets received if the Transfer Agent receives the fee applicable to the extension of the redemption distribution date which the Managing Owner may, from time to time, determine and the remaining Baskets to be redeemed are credited to the Fund’s DTC account by 2:45 p.m., Eastern time, on such next business day. Any further outstanding amount of the redemption order will be cancelled. The Managing Owner is also authorized to deliver the redemption distribution notwithstanding that the

Baskets to be redeemed are not credited to the Fund’s DTC account by 2:45 p.m., Eastern time, on the redemption order settlement date if the Authorized Participant has collateralized its obligation to deliver the Baskets through DTC’s book-entry system on such terms as the Managing Owner may determine from time to time.

Suspension, Postponement or Rejection of Redemption Orders

The Managing Owner may, in its discretion, suspend the right of redemption, or postpone the redemption order settlement date, for (1) any period during which an emergency exists as a result of which the redemption distribution is not reasonably practicable, or (2) such other period as the Managing Owner determines to be necessary for the protection of the Shareholders. The Managing Owner will not be liable to any person or in any way for any loss or damages that may result from any such suspension or postponement.

The Managing Owner or the Transfer Agent may reject a redemption order if the order is not in proper form as described in the Participant Agreement. The Managing Owner or the Transfer Agent will reject a redemption order if the acceptance or receipt of the order, in the opinion of its counsel, might be unlawful.

Creation and Redemption Transaction Fee

To compensate the Transfer Agent for services in processing the creation and redemption of Baskets, an Authorized Participant is required to pay a transaction fee of $500 per order to create or redeem Baskets. An order may include multiple Baskets. The transaction fee may be reduced, increased or otherwise changed by the Managing Owner. The Managing Owner will notify DTC of any agreement to change the transaction fee and will not implement any increase in the fee for the redemption of Baskets until 30 days after the date of the notice.

Monthly account statements conforming to CFTC and NFA requirements are posted on the Managing Owner’s website athttp://www.powershares.com. Additional reports may be posted on the Managing Owner’s website in the discretion of the Managing Owner or as required by regulatory authorities.

THE COMMODITY BROKER

A variety of executing brokers execute futures transactions on behalf of the Fund. Such executing brokersgive-up all such transactions to the Commodity Broker, Morgan Stanley & Co. LLC. 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.

On June 1, 2011, Morgan Stanley & Co. Incorporated converted from a Delaware corporation to a Delaware limited liability company. As a result of that conversion, Morgan Stanley & Co. Incorporated is now named Morgan Stanley & Co. LLC (“MS&Co.”).

MS&Co. is a wholly-owned, indirect subsidiary of Morgan Stanley, a Delaware holding company. Morgan Stanley files periodic reports with the SEC as required by the Securities Exchange Act of 1934 (the “Exchange Act”), which include current descriptions of material litigation and material proceedings and investigations, if any, by governmental and/or regulatory agencies or self-regulatory organizations concerning Morgan Stanley and its subsidiaries, including MS&Co. As a consolidated subsidiary of Morgan Stanley, MS&Co. does not file its own periodic reports with the SEC that contain descriptions of material litigation, proceedings and investigations. As a result, we refer you to the “Legal Proceedings” section of Morgan Stanley’s SEC10-K filings for 2017, 2016, 2015, 2014 and 2013.

In addition to the matters described in those filings, in the normal course of business, each of Morgan Stanley and MS&Co. has been named, from time to time, as a defendant in various legal actions, including arbitrations, class actions, and other litigation, arising in connection with its activities as a global diversified financial services institution. Certain of the legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. Each of Morgan Stanley and MS&Co. is also involved, from time to time, in investigations and proceedings

by governmental and/or regulatory agencies or self-regulatory organizations, certain of which may result in adverse judgments, fines or penalties. The number of these investigations and proceedings has increased in recent years with regard to many financial services institutions, including Morgan Stanley and MS&Co.

MS&Co. is a Delaware limited liability company with its main business office located at 1585 Broadway, New York, New York 10036. Among other registrations and memberships, MS&Co. is registered as a futures commission merchant and is a member of the NFA.

Regulatory and Governmental Matters

In the normal course of business, Morgan Stanley receives subpoenas and requests for information from certain federal and state regulatory and governmental entities, including among others various members of the RMBS Working Group of the Financial Fraud Enforcement Task Force, such as the United States Department of Justice, Civil Division and several state Attorney General’s Offices, concerning the origination, financing, purchase, securitization and servicing of subprime andnon-subprime residential mortgages and related matters such as residential mortgage backed securities (“RMBS”), collateralized debt obligations (“CDOs”), structured investment vehicles (“SIVs”) and credit default swaps backed by or referencing mortgage pass-through certificates. These matters, some of which are in advanced stages, include, but are not limited to, investigations related to MS&Co.’s due diligence on the loans that it purchased for securitization, MS&Co.’s communications with ratings agencies, MS&Co.’s disclosures to investors, and MS&Co.’s handling of servicing and foreclosure related issues.

On February 25, 2015, MS&Co. reached an agreement in principle with the United States Department of Justice, Civil Division and the United States Attorney’s Office for the Northern District of California, Civil Division (collectively, the “Civil Division”) to pay $2.6 billion to resolve certain claims that the Civil Division indicated it intended to bring against MS&Co. That settlement was finalized on February 10, 2016.

California state court styled California v. Morgan Stanley, et al., on behalf of California investors, including the California Public Employees’ Retirement System and the California Teachers’ Retirement System. The complaint alleges that MS&Co. made misrepresentations and omissions regarding residential mortgage-backed securities and notes issued by the Cheyne SIV, and asserts violations of the California False Claims Act and other state laws and seeks treble damages, civil penalties, disgorgement, and injunctive relief. On September 30, 2016, the court granted MS&Co.’s demurrer, with leave to replead. On October 21, 2016, the California Attorney General filed an amended complaint. On January 25, 2017, the court denied MS&Co.’s demurrer with respect to the amended complaint.

In October 2014, the Illinois Attorney General’s Office (“ILAG”) sent a letter to MS&Co. alleging that MS&Co. knowingly made misrepresentations related to RMBS purchased by certain pension funds affiliated with the State of Illinois and demanding that MS&Co. pay ILAG approximately $88 million. MS&Co. and ILAG reached an agreement to resolve the matter on February 10, 2016.

On January 13, 2015, the New York Attorney General’s Office (“NYAG”), which is also a member of the RMBS Working Group, indicated that it intends to file a lawsuit related to approximately 30 subprime securitizations sponsored by MS&Co. NYAG indicated that the lawsuit would allege that MS&Co. misrepresented or omitted material information related to the due diligence, underwriting and valuation of the loans in the securitizations and the properties securing them and indicated that its lawsuit would be brought under the Martin Act. MS&Co. and NYAG reached an agreement to resolve the matter on February 10, 2016.

On July 23, 2014, the “SEC” approved a settlement by MS&Co. and certain affiliates to resolve an investigation related to certain subprime RMBS transactions sponsored and underwritten by those entities in 2007.

CBOE alleged that MS&Co. violated CBOE Rules 4.1, 4.2 and 4.7, Sections 9(a) and 10(b) of the Exchange Act, and Rule10b-5 thereunder. CFE alleged that MS&Co. violated CFE Rules 608, 609 and 620. The matters were resolved on June 28, 2016, in which there were no findings of fraud, but MS&Co. was jointly and severally liable for a $400,000 fine and $152,664 in disgorgement.

On June 18, 2015, MS&Co. entered into a settlement with the SEC and paid a fine of $500,000 as part of the MCDC Initiative to resolve allegations that MS&Co. failed to form a reasonable basis through adequate due diligence for believing the truthfulness of the assertions by issuers and/or obligors regarding their compliance with previous continuing disclosure undertakings pursuant toRule 15c2-12 in connection with offerings in which MS&Co. acted as senior or sole underwriter.

On August 6, 2015, MS&Co. consented to and became the subject of an order by the CFTC to resolve allegations that MS&Co. violated CFTC Regulation 22.9(a) by failing to hold sufficient U.S. Dollars in cleared swap segregated accounts in the United States to meet all U.S. Dollar obligations to cleared swaps customers. Specifically, the CFTC found that while MS&Co. at all times held sufficient funds in segregation to cover its obligations to its customers, on certain days during 2013 and 2014, it held currencies, such as euros, instead of U.S. dollars, to meet its U.S. dollar obligations. In addition, the CFTC found that MS&Co. violated Regulation 166.3 by failing to have in place adequate procedures to ensure that it complied with Regulation 22.9(a). Without admitting or denying the findings or conclusions and without adjudication of any issue of law or fact, MS&Co. accepted and consented to the entry of findings, the imposition of a cease and desist order, a civil monetary penalty of $300,000, and undertakings related to public statements, cooperation, and payment of the monetary penalty.

Without admitting or denying the underlying allegations and without adjudication of any issue of law or fact, MS&Co. consented to a cease and desist order, a censure, and a civil monetary penalty of $7,500,000.

On September 28, 2017, the CFTC issued an order filing and simultaneously settling charges against MS&Co. regarding violations of CFTC Rule 166.3 by failing to diligently supervise the reconciliation of exchange and clearing fees with the amounts it ultimately charged customers for certain transactions on multiple exchanges.

CONFLICTS OF INTEREST

General

The Managing Owner has not established formal procedures to resolve all potential conflicts of interest. Consequently, investors may be 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 Funds and the Shareholders.

Prospective investors should be aware that the Managing Owner presently intends to assert that Shareholders have, by subscribing for Shares of a Fund, consented to the following conflicts of interest in the event of any proceeding alleging that such conflicts violated any duty owed by the Managing Owner to investors.

The Managing Owner

The Managing Owner has a conflict of interest in allocating its own limited resources among different clients and potential future business ventures, to each of which it owes fiduciary duties.

Certain of the professional staff of the Managing Owner may also service other affiliates of the Managing Owner and their respective clients The Managing Owner may, from time to time, have conflicting demands in respect of its obligations to the Funds and to other commodity pools and accounts. It is possible that current or future pools that the Managing Owner operates or advises may generate larger fees than the fees that the Managing Owner receives from any of the Funds. In such a scenario, the Managing Owner’s principals and employees may receive a greater portion of their compensation from those other mandates. Any such increase in fee income for the Managing Owner or compensation for its principals and employees would create an incentive to expend greater resources on those other mandates than on operating and advising the Funds. The Managing Owner intends to devote, and to cause its professional staff to devote, sufficient time and resources to manage properly the business and affairs of the Funds consistent with its or their respective fiduciary duties to the Funds and others.

The Managing Owner has a conflict of interest in the selection of affiliated money market mutual funds and/orT-Bill ETFs in which each of the Funds may invest a portion of its cash for margin and/or cash management purposes. The Managing Owner may choose to invest a portion of each of the Fund’s cash in an affiliated money market mutual fund and/orT-Bill ETF despite the fact thatnon-affiliated money market mutual funds orT-Bill ETFs may pay a higher dividend and/or make a bigger distribution of capital gains. In addition, the Managing Owner would have a conflict of interest if it sought to redeem a Fund’s interest in an affiliated money market mutual fund orT-Bill ETF in circumstances where such a redemption would be unfavorable for the affiliated fund.

The Trust Agreement provides that in the case of a conflict of interest between the Managing Owner or any of its affiliates, on the one hand, and the Trust or any other person, on the other hand, the Managing Owner shall resolve such conflict of interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry practices, and any applicable generally accepted accounting practices or principles. In the absence of bad faith by the Managing Owner, the resolution, action or terms so made, taken or provided by the Managing Owner shall not constitute a breach of the Trust Agreement or any duty or obligation of the Managing Owner.

There is an absence of arm’s length negotiation with respect to some of the terms of these offerings, and there has been no independent due diligence conducted with respect to these offerings.

Invesco Distributors

The Commodity Broker

The Commodity Broker may act from time to time as a commodity broker for other accounts with which it is affiliated or in which it or one of its

affiliates has a financial interest. The compensation received by the Commodity Broker from such accounts may be more or less than the compensation received for brokerage services provided to each Fund. Customers of the Commodity Broker who maintain commodity trading accounts may pay commissions at negotiated rates which are greater or less than the rate paid by the Funds. In addition, various accounts traded through the Commodity Broker (and over which their personnel may have discretionary trading authority) may take positions in the futures markets opposite those of each Fund or may compete with each Fund for the same positions. The Commodity Broker may have a conflict of interest in its execution of trades for each Fund and for other customers. The Managing Owner will, however, not retain any commodity broker for a Fund which the Managing Owner has reason to believe would knowingly or deliberately favor any other customer over a Fund with respect to the execution of commodity trades.

The Commodity Broker will benefit from executing orders for other clients, whereas each Fund may be harmed to the extent that the Commodity Broker has fewer resources to allocate to such Fund’s accounts due to the existence of such other clients.

Certain officers or employees of the Commodity Broker may be members of United States futures exchanges and/or serve on the governing bodies and standing committees of such exchanges, their clearing houses and/or various other industry organizations. In such capacities, these officers or employees may have a fiduciary duty to the exchanges, their clearing houses and/or such various other industry organizations which could compel such employees to act in the best interests of these entities, perhaps to the detriment of a Fund.

Deutsche Bank Securities Inc., which serves as each Fund’s Index Sponsor and Marketing Agent, also serves as an executing commodity broker. Therefore, Deutsche Bank Securities Inc., in its capacity as an executing commodity broker, is also subject to a number of the same conflicts that are described above with respect to the Commodity Broker.

The Index Sponsor and the Marketing Agent

Deutsche Bank Securities Inc., in its capacity as each Fund’s Index Sponsor and Marketing Agent, has

a conflict of interest in allocating its own limited resources among different clients and potential future business ventures. Certain of the professional staff of Deutsche Bank Securities Inc. may also service other affiliates of Deutsche Bank Securities Inc. and their respective clients. Deutsche Bank Securities Inc., in its capacity as each Fund’s Index Sponsor and Marketing Agent may, from time to time, have conflicting demands in respect of its obligations to each Fund and to other clients. It is possible that current or future pools that Deutsche Bank Securities Inc. may become involved with in its capacity as each Fund’s Index Sponsor and Marketing Agent may generate larger fees, resulting in possibly increased payments to employees.

Proprietary Trading/Other Clients

The Managing Owner will not trade proprietary accounts.

The principals of the Managing Owner may trade for their own proprietary accounts (subject to certain internal Invesco Ltd. employee trading policies and procedures) at the same time that they are managing the account of each Fund. As a result, the principals’ own trading activities may result in the principals taking positions in their personal trading accounts that are opposite to those held by each Fund, may trade ahead of each Fund, may compete with each Fund for positions in the marketplace and may give preferential treatment to these proprietary accounts. Records of the Managing Owner principals’ personal trading accounts will not be available for inspection by Shareholders.

The Commodity Broker, its principals and its affiliates may trade in the commodity and foreign exchange markets for their proprietary accounts and for the accounts of their clients. In doing so, they may take positions opposite to those held by each Fund, may trade ahead of each Fund, may compete with each Fund for positions in the marketplace and may give preferential treatment to these proprietary andnon-proprietary accounts. Such trading may create conflicts of interest in respect of their obligations to each Fund. Records of proprietary trading and trading on behalf of other clients will not be available for inspection by Shareholders.

The Funds

Solely for the purposes of thissub-section, the term “Fund” or “Funds” refers to all the series of the Trust. The term “Offered Funds” refer to the series that are offered pursuant to this Prospectus, namely, PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund, PowerShares DB Gold Fund and PowerShares DB Base Metals Fund. The term “Other Funds” refer to the remaining series of the Trust that are not offered pursuant to this Prospectus, namely, PowerShares DB Silver Fund and PowerShares DB Agriculture Fund.

The Trust was formed and is operated in a manner such that each Fund is liable only for obligations attributable to such Fund and Shareholders of a Fund are not subject to the losses or liabilities of any other Fund. For example, if any creditor or Shareholder in any particular Fund asserted against a Fund a valid claim with respect to its indebtedness or Shares, the creditor or Shareholder would only be able to recover money from that particular Fund and its assets. Accordingly, the debts, liabilities, obligations and expenses (collectively, the “Claims”) incurred, contracted for or otherwise existing solely with respect to a particular Fund are enforceable only against the assets of that Fund and not against any other Fund or the Trust generally or any of their respective assets. The assets of any particular Fund include only those funds and other assets that are paid to, held by or distributed to the Fund, including, without limitation, funds delivered to the Trust for the purchase of Shares in a Fund (the “Inter-Series Limitation on Liability”). The Inter-Series Limitation on Liability is expressly provided for under the Delaware Statutory Trust Act, which provides that if certain conditions (as set forth in Section 3804(a)) are met, then the debts of any particular series will be enforceable only against the assets of such series and not against the assets of any other Fund or the Trust generally. The Inter-Series Limitation on Liability applies to all series of the Trust, including both the Offered Funds and the Other Funds.

In furtherance of the Inter-Series Limitation on Liability, every party providing services to the Trust, any Fund or the Managing Owner on behalf of the Trust or any Fund has acknowledged and consented in writing to the Inter-Series Limitation on Liability with respect to such party’s Claims.

No special custody arrangements are applicable to any Fund, and the existence of a trustee should not be taken as an indication of any additional level of management or supervision over any Fund. Under the Trust Agreement, the Managing Owner has exclusive management and control of all aspects of the business of the Funds.

The Trust Agreement gives Shareholders of each Offered Fund voting rights in respect of the business and affairs of such Offered Fund comparable to those typically extended to limited partners in publicly-offered futures funds.

Shareholders, voting together as a single series, may, however, remove and replace the Managing Owner as the managing owner of the Trust and all of the Funds, and may amend the Trust Agreement, except in certain limited respects, by the affirmative vote of a majority of the outstanding Shares then owned by Shareholders (not including Shares held by the Managing Owner and its affiliates).

The Trust Agreement permits the approval of actions through the negative consent of Shareholders. As provided by Section 11.3 of the Trust Agreement, the vote or consent of each Shareholder so solicited will be deemed conclusively to have been cast or granted as requested in the notice of solicitation, whether or not the notice of solicitation is actually received by that Shareholder, unless the Shareholder expresses written objection to the vote or consent by notice given in the manner provided in the Trust Agreement and actually received by the Trust within twenty (20) days after the notice of solicitation is effected. Because Section 11.3 of the Trust Agreement provides for negative consent (e.g., that Shareholders are deemed to have consented unless they timely object), your consent will be deemed conclusively to have been granted with respect to any matter for which the Managing Owner may solicit your consent unless you express written objection in the manner required by the Trust Agreement and your written objection is actually received by the Trust within twenty (20) days after the notice of solicitation is effected. This means that not responding to the vote or consent solicitation would have the same effect as responding with your affirmative written consent. For example, in the context of a consent solicitation to change the managing owner or any other action, your lack of a response will have the same effect as if you had provided your affirmative written consent for the proposed action.

The Managing Owner and all persons dealing with the Trust will be entitled to act in reliance on any vote or consent which is deemed cast or granted pursuant to the negative consent provision and will be fully indemnified by the Trust in so doing. Any action taken or omitted in reliance on this deemed vote or consent of one or more Shareholders will not be void or voidable by reason of timely

101

communication made by or on behalf of all or any of these Shareholders in any manner other than as expressly provided in the Trust Agreement.

The Managing Owner has the unilateral right to amend the Trust Agreement as it applies to any Fund provided that any such amendment is for the benefit of and not adverse to the Shareholders of such Fund or the Trustee and also in certain unusual circumstances, for example, if doing so is necessary to comply with certain regulatory requirements.

Recognition of the Trust and the Funds in Certain States

A number of states do not have “business trust” statutes such as that under which the Trust has been formed in the State of Delaware. It is possible, although unlikely, that a court in such a state could hold that, due to the absence of any statutory provision to the contrary in such jurisdiction, the Shareholders, although entitled under Delaware law to the same limitation on personal liability as stockholders in a private corporation for profit organized under the laws of the State of Delaware, are not so entitled in such state. To protect Shareholders against any loss of limited liability, the Trust Agreement provides that no written obligation may be undertaken by any Fund unless such obligation is explicitly limited so as not to be enforceable against any Shareholder personally. Furthermore, each Fund itself indemnifies all its Shareholders against any liability that such Shareholders might incur in addition to that of a beneficial owner.

Possible Repayment of Distributions Received by Shareholders; Indemnification by Shareholders

The Shares are limited liability investments; investors may not lose more than the amount that they invest plus any appreciation in their investments. However, Shareholders of a Fund could be required, as a matter of bankruptcy law, to return to the estate of such Fund any distribution they received at a time when such Fund was in fact insolvent or in violation of the Trust Agreement. In addition, Shareholders of each Fund agree in the Trust Agreement that they will indemnify such Fund for any harm suffered by it as a result of

•

Shareholders’ actions unrelated to the business of such Fund, or

•

taxes separately imposed on the Fund by any state, local or foreign taxing authority.

Shares Freely Transferable

The Shares of each Fund trade on the NYSE Arca and provide institutional and retail investors with direct access to each Fund. Each Fund trades with a view of tracking its Index, over time, less expenses. The Shares of each Fund may be bought and sold on the NYSE Arca.

Book-Entry Form

Individual certificates will not be issued for the Shares. Instead, global certificates are deposited by the Trustee with DTC and registered in the name of Cede & Co., as nominee for DTC. The global certificates evidence all of the Shares outstanding at any time. Under the Trust Agreement, Shareholders are limited to (1) participants in DTC such as banks, brokers, dealers and trust companies (“DTC Participants”), (2) those who maintain, either directly or indirectly, a custodial relationship with a DTC Participant (“Indirect Participants”), and (3) those banks, brokers, dealers, trust companies and others who hold interests in the Shares through DTC Participants or Indirect Participants. The Shares are only transferable through the book-entry system of DTC. Shareholders who are not DTC Participants may transfer their Shares through DTC by instructing the DTC Participant holding their Shares (or by instructing the Indirect Participant or other entity through which their Shares are held) to transfer the Shares. Transfers are made in accordance with standard securities industry practice.

Reports to Shareholders

The Managing Owner will furnish you with an annual report of each Fund within 90 calendar days after the end of its fiscal year as required by the rules and regulations of the SEC as well as with those reports required by the CFTC and the NFA, including, but not limited to, annual audited financial statements certified by independent registered public accountants and any other reports required by any other governmental authority that has jurisdiction over the activities of the Trust and each Fund. You also will be provided with appropriate information to permit you to file your U.S. federal and state income tax returns (on a timely basis) with respect to your

102

Shares. Monthly account statements conforming to CFTC and NFA requirements are posted on the Managing Owner’s website athttp://www.powershares.com. Additional reports may be posted on the Managing Owner’s website in the discretion of the Managing Owner or as required by applicable regulatory authorities.

The Managing Owner will notify Shareholders of any change in the fees paid by the Trust or of any material changes to any Fund by filing with the SEC a supplement to this Prospectus and aForm 8-K, which will be publicly available athttp://www.sec.gov and at the Managing Owner’s website athttp://www. powershares.com. Any such notification will include a description of Shareholders’ voting rights.

NAV

NAV, in respect of any 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 such Fund, each determined on the basis of generally accepted accounting principles in the United States, consistently applied under the accrual method of accounting. In particular, NAV includes any unrealized profit or loss on open futures positions, and any other credit or debit accruing to a Fund but unpaid or not received by a Fund. All open commodity futures contracts traded on a U.S. exchange are calculated at their then current market value, which are based upon the settlement price for that particular commodity futures contract traded on the applicable U.S. exchange on the date with respect to which NAV is being determined; provided, that if a commodity futures contract or option traded on a U.S. exchange 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 or option pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. The current market value of all open commodity futures contracts traded on anon-United States exchange will be based upon the settlement price for that particular commodity futures contract traded on the applicablenon-U.S. exchange on the date with respect to which NAV is being determined; provided further, that if a futures contract traded on anon-U.S. exchange, to the extent applicable, could not be liquidated on such day, due

to the operation of daily limits (if applicable) 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. The current market value of all open forward contracts entered into by a Fund, if any, shall be the mean between the last bid and last asked prices quoted by the bank or financial institution which is a party to the contract on the date with respect to which NAV is being determined; provided, that if such quotations are not available on such date, the mean between the last bid and asked prices on the first subsequent day on which such quotations are available shall be the basis for determining the market value of such forward contract for such day. The Managing Owner may in its discretion (and under extraordinary circumstances, including, but not limited to, periods during which a settlement price of a futures contract is not available due to exchange limit orders or force majeure type events such as systems failure, natural orman-made disaster, act of God, armed conflict, act of terrorism, riot or labor disruption or any similar intervening circumstance) value any asset of a Fund pursuant to such other principles as the Managing Owner deems fair and equitable so long as such principles are consistent with normal industry standards. Interest earned on any Fund’s commodity brokerage account is accrued at least monthly. The amount of any distribution will be a liability of such Fund from the day when the distribution is declared until it is paid.

NAV per Share, in respect of any Fund, is the NAV of the Fund divided by the number of the Fund’s outstanding Shares.

Termination Events

The Trust, or, as the case may be, any Fund, will dissolve at any time upon the happening of any of the following events:

•

The filing of a certificate of dissolution or revocation of the Managing Owner’s charter (and the expiration of 90 days after the date of notice to the Managing Owner of revocation without a reinstatement of its charter) or upon the withdrawal, removal, adjudication or admission of bankruptcy or insolvency of the Managing Owner, or an event of withdrawal unless (i) at the time

103

there is at least one remaining managing owner and that remaining managing owner carries on the business of the Fund or (ii) within 90 days of such event of withdrawal all the remaining Shareholders agree in writing to continue the business of a Fund and to select, effective as of the date of such event, one or more successor managing owners. If the Trust is terminated as the result of an event of withdrawal and a failure of all remaining Shareholders to continue the business of the Trust and to appoint a successor managing owner as provided above within 120 days of such event of withdrawal, Shareholders holding Shares representing at least a majority (over 50%) of the NAV of each Fund (not including Shares held by the Managing Owner and its affiliates) may elect to continue the business of the Trust by forming a new statutory trust (“Reconstituted Trust”) on the same terms and provisions as set forth in the Trust Agreement (whereupon the Managing Owner and the Trustee shall execute and deliver any documents or instruments as may be necessary to reform the Trust). Any such election must also provide for the election of a managing owner to the Reconstituted Trust. If such an election is made, all Shareholders of the Funds shall be bound thereby and continue as Shareholders of the Reconstituted Trust.

•

The occurrence of any event which would make unlawful the continued existence of the Trust or any Fund, as the case may be.

•

In the event of the suspension, revocation or termination of the Managing Owner’s registration as a commodity pool operator or commodity trading advisor under the Commodity Exchange Act, or membership as a commodity pool operator or commodity trading advisor with the NFA (if, in either case, such registration is required under the Commodity Exchange Act or the rules promulgated thereunder) unless at the time there is at least one remaining managing owner whose registration or membership has not been suspended, revoked or terminated.

•

The Trust or any Fund, as the case may be, becomes insolvent or bankrupt.

•

The Shareholders holding Shares representing at least a majority (over 50%) of the NAV (which excludes the Shares of the Managing Owner) vote to dissolve the Trust, notice of which is sent to the Managing Owner not less than ninety (90) Business Days prior to the effective date of termination.

•

The determination of the Managing Owner that the aggregate net assets of a Fund in relation to the operating expenses of such Fund make it unreasonable or imprudent to continue the business of such Fund, or, in the exercise of its reasonable discretion, the determination by the Managing Owner to dissolve the Trust because the aggregate NAV of the Trust as of the close of business on any business day declines below $10 million.

•

The Trust or any Fund is required to be registered as an investment company under the Investment Company Act of 1940, as amended.

•

DTC is unable or unwilling to continue to perform its functions, and a comparable replacement is unavailable.

DISTRIBUTIONS

Each Fund will make distributions at the discretion of the Managing Owner.

To the extent that a Fund’s actual and projected Treasury Income, actual and projected Money Market Income and a Fund’s actual and actual and projectedT-Bill ETF Income exceeds the actual and projected fees and expenses of such Fund, the Managing Owner expects periodically to make distributions of the amount of such excess. The Managing Owner currently does not expect to make distributions with respect to capital gains for any of the Funds. Depending on the applicable 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 such Fund’s net ordinary income or loss and capital gain or loss may exceed any distributions you receive with respect to such year.

104

105

INDEX SPONSOR

The Index Sponsor also calculates the IIV per Share of each Fund throughout each Business Day. The Index Sponsor may subcontract its services from time to time to one or more third parties.

The Managing Owner pays the Index Sponsor a licensing fee and an index services fee out of the Management Fee for performing its duties. These fees constitute a portion of the routine operational, administrative and other ordinary expenses and are paid from out of the applicable Management Fee and are not charged to or reimbursed by the Funds.

Neither the Managing Owner nor any affiliate of the Managing Owner has any rights to influence the selection of the futures contracts underlying each Index.

The Index Sponsor is not affiliated with each Fund or the Managing Owner. The Managing Owner has entered into a license agreement with the Index Sponsor to use each Index.

Each Fund is not sponsored, endorsed, sold or promoted by the Index Sponsor, and the Index Sponsor makes no representation regarding the advisability of investing in Shares of each Fund.

There is no relationship between the Index Sponsor and the Managing Owner or each Fund other than a services agreement and a license by the Index Sponsor to the Managing Owner of certain of the Index Sponsor’s trademarks and trade names, and each Index, for use by the Managing Owner or each Fund. Such trademarks, trade names and each Index have been created and developed by the Index Sponsor without regard to, and independently of, the Managing Owner and each Fund, their businesses, and/or any prospective investor. Each Fund and the Managing Owner have arranged with the Index Sponsor to license each Index for possible inclusion in funds which the Managing Owner independently intends to develop and promote. The Index Sponsor is not responsible for and has not participated in the

determination of the prices and amount of Shares of each Fund or the timing of the issuance or sale of Shares of each Fund or in the determination of any financial calculations relating thereto. The Index Sponsor has no obligation or liability in connection with the administration of each Fund, or marketing of the Shares of each Fund. The Index Sponsor does not guarantee the accuracy and/or the completeness of each Index or any data included therein. The Index Sponsor shall have no liability for any errors, omissions, or interruptions therein. The Index Sponsor makes no warranty, express or implied, as to results to be obtained by the Managing Owner, each Fund or owners of Shares, or any other person or entity, from the use of the Index or any data included therein. The Index Sponsor makes no express or implied warranties, and expressly disclaims all warranties of merchantability or fitness for a particular purpose or use with respect to each Index or any data included therein, each Fund, or the Shares of each Fund. Deutsche Bank Securities Inc. has entered into a services agreement with the Managing Owner. The agreement between the Managing Owner and DBSI as Index Sponsor relates to the Managing Owner’s sponsorship not only of the Funds but of other commodity pools and ETFs. The agreement is for an initial six year term which commenced on February 26, 2015, with additionalone-year renewal terms unless terminated.

Both the Managing Owner and DBSI have the right to terminate on notice subject to payment of a termination fee, both with respect to a given fund and with respect to all funds subject to these agreements. Each party also has the right to terminate for cause, although the Managing Owner’s ability to exercise this right is restricted to a narrow set of circumstances during the initialsix-year term. Accordingly, there may be circumstances where the Managing Owner would otherwise believe cause exists to terminate DBSI but where it would have to rely on its right to terminate at will. The termination fee payable by the Managing Owner would be based on anticipated fee payments under these agreements during the remainder of the initialsix-year term, and therefore could be sufficiently high as to deter the Managing Owner from exercise of these termination rights. These termination fees would also be triggered by certain other termination rights of DBSI, including in the event of a change of control of the Managing Owner or changes of law affecting the licenses or services to be provided by DBSI. As a consequence

106

of these termination fee rights, DBSI may elect to terminate these licenses and services under certain circumstances where, were these being provided under stand-alone arrangements in respect of the Funds, it might not elect to terminate the business relationship. Termination of the agreements between DBSI and the Managing Owner could result in disruption to the affairs of the Funds, including the need to adopt new indices and engage a replacement index sponsor.

Without limiting any of the foregoing, in no event shall the Index Sponsor have any liability for any special, punitive, indirect, or consequential damages (including lost profits) resulting from the use of each Index or any data included therein, each Fund, or the Shares of each Fund, even if notified of the possibility of such damages.

The Index Sponsor shall not be liable to the Managing Owner, each Fund, or the owners of any Shares of each Fund for any loss or damage, direct or indirect, arising from (i) any inaccuracy or incompleteness in, or delays, interruptions, errors or omissions in the delivery of each Index or any data related thereto, the Index Data, or (ii) any decision made or action taken by any customer or third party in reliance upon the Index Data. The Index Sponsor does not make any warranties, express or implied, to the Managing Owner, each Fund or owners of Shares or anyone else regarding the Index Data, including without limitation, any warranties with respect to the timeliness, sequence, accuracy, completeness, currentness, merchantability, quality, or fitness for a particular purpose or any warranties as to the results to be obtained by the Managing Owner, each Fund or owners of Shares or anyone else in connection with the use of the Index Data. The Index Sponsor shall not be liable to the Managing Owner, each Fund or owners of Shares or anyone else for loss of business revenues, lost profits or any indirect, consequential, special or similar damages whatsoever, whether in contract, tort or otherwise, even if advised of the possibility of such damages.

The Managing Owner does not guarantee the accuracy and/or the completeness of each Index or any Index Data included therein, and the Managing Owner shall have no liability for any errors, omissions, or interruptions therein. The Managing Owner makes no warranty, express or implied, as to results to be obtained by each Fund, owners of the Shares of each Fund or any other person or entity from the use of each Index or any Index Data

included therein. The Managing Owner makes no express or implied warranties, and expressly disclaims all warranties of merchantability or fitness for a particular purpose or use with respect to each Underlying Index or any Index Data included therein. Without limiting any of the foregoing, in no event shall the Managing Owner have any liability for any special, punitive, direct, indirect or consequential damages (including lost profits) arising out of matters relating to the use of each Index even if notified of the possibility of such damages.

MARKETING AGENT

Pursuant to a services agreement, the Managing Owner, on behalf of each Fund, has appointed Deutsche Bank Securities Inc. as Marketing Agent to assist the Managing Owner by providing support to educate institutional investors about the Deutsche Bank indices and to complete governmental or institutional due diligence questionnaires or requests for proposals related to the Deutsche Bank indices.

The Managing Owner pays the Marketing Agent a marketing services fee out of the Management Fee for performing its duties.

The agreement between the Managing Owner and DBSI as Marketing Agent relates to not only the Fund but to other commodity pools and ETFs. The agreement is for an initial six year term which commenced on February 26, 2015, with additionalone-year renewal terms unless terminated.

THE SECURITIES DEPOSITORY; BOOK-

ENTRY-ONLY SYSTEM; GLOBAL SECURITY

DTC acts as securities depository for the Shares. DTC is a limited-purpose trust company organized

107

under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York

Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of section 17A of the Exchange Act. DTC was created to hold securities of DTC Participants and to facilitate the clearance and settlement of transactions in such securities among the DTC Participants through electronic book-entry changes. This eliminates the need for physical movement of securities certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations, some of whom (and/or their representatives) own DTC. Access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly. DTC has agreed to administer its book-entry system in accordance with its rules andby-laws and the requirements of law.

Individual certificates will not be issued for the Shares. Instead, global certificates are signed by the Managing Owner on behalf of each Fund, registered in the name of Cede & Co., as nominee for DTC, and deposited with the Trustee on behalf of DTC. The global certificates evidence all of the Shares of each Fund outstanding at any time. The representations, undertakings and agreements made on the part of each Fund in the global certificates are made and intended for the purpose of binding only the applicable Fund and not the Trustee or the Managing Owner individually.

Upon the settlement date of any creation, transfer or redemption of Shares, DTC credits or debits, on its book-entry registration and transfer system, the amount of the Shares so created, transferred or redeemed to the accounts of the appropriate DTC Participants. The Managing Owner and the Authorized Participants designate the accounts to be credited and charged in the case of creation or redemption of Shares.

Beneficial ownership of the Shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Owners of beneficial interests

in the Shares is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants), the records of DTC Participants (with respect to Indirect Participants), and the records of Indirect Participants (with respect to Shareholders that are not DTC Participants or Indirect Participants). Shareholders are expected to receive from or through the DTC Participant maintaining the account through which the Shareholder has purchased their Shares a written confirmation relating to such purchase.

Shareholders that are not DTC Participants may transfer the Shares through DTC by instructing the DTC Participant or Indirect Participant through which the Shareholders hold their Shares to transfer the Shares. Shareholders that are DTC Participants may transfer the Shares by instructing DTC in accordance with the rules of DTC. Transfers are made in accordance with standard securities industry practice.

DTC may decide to discontinue providing its service with respect to Baskets and/or the Shares of each Fund by giving notice to the Trustee and the Managing Owner. Under such circumstances, the Trustee and the Managing Owner will either find a replacement for DTC to perform its functions at a comparable cost or, if a replacement is unavailable, terminate such Fund.

The rights of the Shareholders generally must be exercised by DTC Participants acting on their behalf in accordance with the rules and procedures of DTC. Because the Shares can only be held in book-entry form through DTC and DTC Participants, investors must rely on DTC, DTC Participants and any other financial intermediary through which they hold the Shares to receive the benefits and exercise the rights described in this section. Investors should consult with their broker or financial institution to find out about procedures and requirements for securities held in book-entry form through DTC.

SHARE SPLITS

If the Managing Owner believes that the per Share price in the secondary market for Shares has fallen outside a desirable trading price range, the Managing Owner may direct the Trustee to declare a

108

split or reverse split in the number of Shares outstanding and to make a corresponding change in the number of Shares of such Fund constituting a Basket.

MATERIAL CONTRACTS

Brokerage Agreement

The Commodity Broker and the Managing Owner (on behalf of each Fund) entered into a brokerage agreement with respect to each Fund (the “Brokerage Agreement”). As a result, the Commodity Broker:

•

acts as the clearing broker;

•

acts as custodian of each Fund’s assets in connection with the clearing of transactions; and

•

performs such other services for each Fund as the Managing Owner may from time to time request.

As clearing broker for each Fund, the Commodity Broker receives orders for trades from the Managing Owner.

Confirmations of all executed trades are given to each Fund by the Commodity Broker. The Brokerage Agreement incorporates the Commodity Broker’s standard customer agreements and related documents, which generally include provisions that:

•

the assets of each Fund held in its account with the Commodity Broker and all contracts and rights to payment thereunder are held as security for each respective Fund’s obligations to the Commodity Broker;

•

the Commodity Broker shall have the right to limit the size of open positions (net or gross) of each Fund with respect to its account at any time only as necessary to comply with the applicable law or applicable position limits and shall promptly notify the Funds of any rejected order;

•

each Fund must make all applicable original margin, variation margin,intra-day margin and premium payments to the Commodity Broker; the Commodity Broker may, among other things, close out positions, sell

securities or other property held in a Fund’s account, purchase futures or cancel orders at any time upon the default of a Fund under the Brokerage Agreement, without the consent of the Managing Owner on behalf of such Fund; and

•

absent a separate written agreement with a Fund with respect togive-up transactions, the Commodity Broker, in its sole discretion, may accept from other brokers contracts executed by such brokers and to be given up to the Commodity Broker for clearance or carrying in any account.

Administrative functions provided by the Commodity Broker to each Fund include, but are not limited to, preparing and transmitting daily confirmations of transactions and monthly statements of account, calculating balances and margin requirements.

In respect of the transactions effected pursuant to the Brokerage Agreement, the Commodity Broker will charge the Funds a fee for the services it has agreed to perform, including brokerage charges,give-up fees, commissions and services fees as may be agreed upon by the Funds and the Commodity Broker; exchange, clearing house, NFA or other regulatory fees; the amount necessary to hold Commodity Broker harmless against all taxes andtax-related liabilities of each Fund; any debit balance or deficiency in a Fund’s account; interest on any debit balances or deficiencies in a Fund’s account and on monies advanced to each Fund; and any other agreed upon amounts owed by a Fund to the Commodity Broker in connection with such Fund’s account or transactions therein.

The Brokerage Agreement is terminable by each Fund at any time by written notice to the Commodity Broker, or by the Commodity Broker without penalty upon ten (10) days’ prior written notice.

The Brokerage Agreement provides that except to the extent of its gross negligence, fraud or willful misconduct, the Commodity Broker shall not be liable for any loss, liability or expense incurred by each Fund in connection with or arising out of the Brokerage Agreement, transactions in or for each Fund or any actions taken by the Commodity Broker at the request or direction of each Fund.

109

Administration Agreement

Pursuant to the Administration Agreement among the Trust, on behalf of itself and on behalf of each Fund, and the Administrator, the Administrator performs or supervises the performance of services necessary for the operation and administration on behalf of each Fund (other than making investment decisions), including receiving and processing orders from Authorized Participants to create and redeem Baskets, NAV calculations, accounting and other fund administrative services.

The Administration Agreement will continue in effect unless terminated on at least 90 days’ prior written notice by either party to the other party. Notwithstanding the foregoing, the Administrator may terminate the Administration Agreement with respect to a Fund upon 30 days’ prior written notice if the Fund has materially failed to perform its obligations under the Administration Agreement or upon the termination of the Custody Agreement by each Fund.

The Administrator is both exculpated and indemnified under the Administration Agreement.

Except as otherwise provided in the Administration Agreement, the Administrator will not be liable for any costs, expenses, damages, liabilities or claims (including attorneys’ and accountants’ fees) incurred by the Trust or any Fund, except those costs, expenses, damages, liabilities or claims arising out of the Administrator’s own gross negligence or willful misconduct. In no event will the Administrator be liable to the Trust, the Funds or any third party for special, indirect or consequential damages, or lost profits or loss of business, arising under or in connection with the Administration Agreement, even if previously informed of the possibility of such damages and regardless of the form of action. The Administrator will not be liable for any loss, damage or expense, including counsel fees and other costs and expenses of a defense against any claim or liability, resulting from, arising out of, or in connection with its performance under the Administration Agreement, including its actions or omissions, the incompleteness or inaccuracy of any Proper Instructions (as defined therein), or for delays caused by circumstances beyond the Administrator’s control, unless such loss, damage or expense arises out of the gross negligence or willful misconduct of the Administrator.

The Trust and/or each Fund will indemnify and hold harmless the Administrator from and against any and all costs, expenses, damages, liabilities and claims (including claims asserted by the Trust or any Fund), and reasonable attorneys’ and accountants’ fees relating thereto, which are sustained or incurred or which may be asserted against the Administrator by reason of or as a result of any action taken or omitted to be taken by the Administrator in good faith under the Administration Agreement or in reliance upon (i) any law, act, regulation or interpretation of the same even though the same may thereafter have been altered, changed, amended or repealed, (ii) the registration statement or Prospectus, (iii) any Proper Instructions, or (iv) any opinion of legal counsel for any Fund or arising out of transactions or other activities of any Fund which occurred prior to the commencement of the Administration Agreement; provided, that neither the Trust nor any Fund will indemnify the Administrator for costs, expenses, damages, liabilities or claims for which the Administrator is liable under the preceding paragraph. This indemnity will be a continuing obligation of the Trust, each Fund and their respective successors and assigns, notwithstanding the termination of the Administration Agreement. Without limiting the generality of the foregoing, the Trust and each Fund will indemnify the Administrator against and save the Administrator harmless from any loss, damage or expense, including counsel fees and other costs and expenses of a defense against any claim or liability, arising from any one or more of the following: (i) errors in records or instructions, explanations, information, specifications or documentation of any kind, as the case may be, supplied to the Administrator by any third-party described in the Administration Agreement or by or on behalf of the Fund; (ii) action or inaction taken or omitted to be taken by the Administrator pursuant to Proper Instructions of the Trust, on behalf of a Fund, or otherwise without gross negligence or willful misconduct; (iii) any action taken or omitted to be taken by the Administrator in good faith in accordance with the advice or opinion of counsel for the Trust or any Fund or its own counsel; (iv) any improper use by the Trust or any Fund or their respective agents, distributor or investment advisor of any valuations or computations supplied by the Administrator pursuant to the Administration Agreement; (v) the method of valuation and the method of computing NAV; or (vi) any valuations or NAV provided by any Fund.

Actions taken or omitted in reliance on Proper Instructions, or upon any information, order, indenture, stock certificate, power of attorney, assignment, affidavit or other instrument believed by the Administrator to be genuine or bearing the signature of a person or persons believed to be authorized to sign, countersign or execute the same, or upon the opinion of legal counsel for the Trust, on behalf of a Fund, or its own counsel, will be conclusively presumed to have been taken or omitted in good faith.

Notwithstanding any other provision contained in the Administration Agreement, the Administrator will have no duty or obligation with respect to, including, without limitation, any duty or obligation to determine, or advise or notify any Fund of: (a) the taxable nature of any distribution or amount received or deemed received by, or payable to any Fund; (b) the taxable nature or effect on any Fund or its shareholders of any corporate actions, class actions, tax reclaims, tax refunds, or similar events; (c) the taxable nature or taxable amount of any distribution or dividend paid, payable or deemed paid by each Fund to their respective shareholders; or (d) the effect under any federal, state, or foreign income tax laws of each Fund making or not making any distribution or dividend payment, or any election with respect thereto.

Global Custody Agreement

The Bank of New York Mellon serves as the Custodian. Pursuant to the Custody Agreement, the Custodian serves as custodian of all securities and cash at any time delivered to Custodian by each respective Fund during the term of the Custody Agreement and has authorized the Custodian to hold its securities in registered form in its name or the name of its nominees. The Custodian has established and will maintain one or more securities accounts and cash accounts for each Fund pursuant to the Custody Agreement. The Custodian will maintain separate and distinct books and records segregating the assets of each Fund.

The Trust, on behalf of each Fund, independently, and the Custodian may terminate the Custody Agreement by giving to the other party a notice in writing specifying the date of such termination, which will be not less than ninety (90) days after the date of such notice. Upon termination thereof, the applicable Fund will pay to

the Custodian such compensation as may be due to the Custodian, and will likewise reimburse the Custodian for other amounts payable or reimbursable to the Custodian thereunder. The Custodian will follow such reasonable oral or written instructions concerning the transfer of custody of records, securities and other items as the Trust, on behalf of each Fund, gives; provided, that (a) the Custodian will have no liability for shipping and insurance costs associated therewith, and (b) full payment will have been made to the Custodian of its compensation, costs, expenses and other amounts to which it is entitled thereunder. If any securities or cash remain in any account, the Custodian may deliver to the Trust, on behalf of each Fund, such securities and cash. Except as otherwise provided herein, all obligations of the parties to each other hereunder will cease upon termination of the Custody Agreement.

The Custodian is both exculpated and indemnified under the Custody Agreement.

Except as otherwise expressly provided in the Custody Agreement, the Custodian will not be liable for any costs, expenses, damages, liabilities or claims, including attorneys’ and accountants’ fees(collectively referred to in this section as “losses”), incurred by or asserted against the Trust or any Fund, except those losses arising out of the gross negligence or willful misconduct of the Custodian. The Custodian will have no liability whatsoever for the action or inaction of any depository. Subject to the Custodian’s delegation of its duties to its affiliates, the Custodian’s responsibility with respect to any securities or cash held by a subcustodian is limited to the failure on the part of the Custodian to exercise reasonable care in the selection or retention of such subcustodian in light of prevailing settlement and securities handling practices, procedures and controls in the relevant market. With respect to any losses incurred by the Trust or any Fund as a result of the acts or the failure to act by any subcustodian (other than an affiliate of the Custodian), the Custodian will take appropriate action to recover such losses from such subcustodian; and the Custodian’s sole responsibility and liability to the Trust or any Fund will be limited to amounts so received from such subcustodian (exclusive of costs and expenses incurred by the Custodian). In no event will the Custodian be liable to the Trust or any Fund or any third-party for special, indirect or consequential damages, or lost profits or loss of business, arising in connection with the Custody Agreement.

111

The Trust, on behalf of each Fund, as applicable, will indemnify the Custodian and each subcustodian for the amount of any tax that the Custodian, any such subcustodian or any other withholding agent is required under applicable laws (whether by assessment or otherwise) to pay on behalf of, or in respect of income earned by or payments or distributions made to or for the account of each Fund (including any payment of tax required by reason of an earlier failure to withhold). The Custodian will, or will instruct the applicable subcustodian or other withholding agent to, withhold the amount of any tax which is required to be withheld under applicable law upon collection of any dividend, interest or other distribution made with respect to any security and any proceeds or income from the sale, loan or other transfer of any security. In the event that the Custodian or any subcustodian is required under applicable law to pay any tax on behalf of each Fund, the Custodian is hereby authorized to withdraw cash from any cash account in the amount required to pay such tax and to use such cash, or to remit such cash to the appropriate subcustodian, for the timely payment of such tax in the manner required by applicable law.

The Trust, on its own behalf and on behalf of each Fund, will indemnify the Custodian and hold the Custodian harmless from and against any and all losses sustained or incurred by or asserted against the Custodian by reason of or as a result of any action or inaction, or arising out of the Custodian’s performance under the Custody Agreement, including reasonable fees and expenses of counsel incurred by the Custodian in a successful defense of claims by any Fund; provided however, that the Trust, on its own behalf and on behalf of each Fund, as applicable, will not indemnify the Custodian for those losses arising out of the Custodian’s gross negligence or willful misconduct. This indemnity will be a continuing obligation of the Trust, on its own behalf and on behalf of each Fund, as applicable, their successors and assigns, notwithstanding the termination of the Custody Agreement.

Transfer Agency and Service Agreement

The Bank of New York Mellon serves as the Transfer Agent. Pursuant to the Transfer Agency and Service Agreement between the Trust, the Trust on its own behalf and on behalf of each Fund and the

Transfer Agent, the Transfer Agent serves as each Fund’s transfer agent, dividend disbursing agent, and agent in connection with certain other activities as provided under the Transfer Agency and Service Agreement.

The term of the Transfer Agency and Service Agreement is one year from the effective date and will automatically renew for additional one year terms unless either party provides written notice of termination at least ninety (90) days prior to the end of any one year term or, unless earlier terminated as provided below:

•

Either party terminates prior to the expiration of the initial term in the event the other party breaches any material provision of the Transfer Agency and Service Agreement, including, without limitation in the case of the Trust, on behalf of each Fund, its obligations to compensate the Transfer Agent, provided that thenon-breaching party gives written notice of such breach to the breaching party and the breaching party does not cure such violation within ninety (90) days of receipt of such notice.

•

Each Fund may terminate the Transfer Agency and Service Agreement prior to the expiration of the initial term upon ninety (90) days’ prior written notice in the event that the Managing Owner determines to liquidate the Trust or any Fund and terminate its registration with the SEC other than in connection with a merger or acquisition of the Trust.

The Transfer Agent will have no responsibility and will not be liable for any loss or damage unless such loss or damage is caused by its own gross negligence or willful misconduct or that of its employees, or its breach of any of its representations. In no event will the Transfer Agent be liable for special, indirect or consequential damages regardless of the form of action and even if the same were foreseeable.

Pursuant to the Transfer Agency and Service Agreement, the Transfer Agent will not be responsible for, and the Trust or each applicable Fund will indemnify and hold the Transfer Agent harmless from and against, any and all losses,

112

damages, costs, charges, counsel fees, payments, expenses and liability, or losses, arising out of or attributable to:

•

All actions of the Transfer Agent or its agents or subcontractors required to be taken pursuant to the Transfer Agency and Service Agreement, provided that such actions are taken without gross negligence, or willful misconduct.

•

The Trust’s or the respective Fund’s gross negligence or willful misconduct.

•

The breach of any representation or warranty of the Trust thereunder.

•

The conclusive reliance on or use by the Transfer Agent or its agents or subcontractors of information, records, documents or services which (i) are received by the Transfer Agent or its agents or subcontractors, and (ii) have been prepared, maintained or performed by the Trust, on its own behalf or on behalf of any Fund, or any other person or firm on behalf of the Trust or a Fund including but not limited to any previous transfer agent or registrar.

•

The conclusive reliance on, or the carrying out by the Transfer Agent or its agents or subcontractors of any instructions or requests of the Trust, on its own behalf and on behalf of a Fund.

•

The offer or sale of Shares in violation of any requirement under the federal securities laws or regulations or the securities laws or regulations of any state that such Shares be registered in such state or in violation of any stop order or other determination or ruling by any federal agency or any state with respect to the offer or sale of such Shares in such state.

Distribution Services Agreement

Invesco Distributors provides certain distribution services to each Fund. Pursuant to the Distribution Services Agreement between the Trust, with respect to each Fund and Invesco Distributors, as amended from time to time, Invesco Distributors will assist the Managing Owner with certain functions and duties relating to distribution and marketing including reviewing and approving marketing materials.

The date of the Distribution Services Agreement is the effective date and such Agreement will continue automatically for successive annual periods, provided that such continuance is specifically approved (with respect to each Fund) at least annually by the Managing Owner. The Distribution Services Agreement is terminable, with respect to each individual Fund, without penalty on sixty days’ written notice by the Managing Owner or by Invesco Distributors. The Distribution Services Agreement will automatically terminate in the event of its assignment.

Pursuant to the Distribution Services Agreement, each Fund will indemnify Invesco Distributors as follows:

Each Fund indemnifies and holds harmless Invesco Distributors and each of its directors and officers and each person, if any, who controls Invesco Distributors within the meaning of Section 15 of the Securities Act, against any loss, liability, claim, damage or expense (including the reasonable cost of investigating or defending any alleged loss, liability, claim, damage or expense and reasonable counsel fees incurred in connection therewith) by reason of any person acquiring any Shares, based upon the ground that the registration statement, Prospectus, Statement of Additional Information, shareholder reports or other information filed or made public by each respective Fund (as from time to time amended) included an untrue statement of a material fact or omitted to state a material fact required to be stated or necessary in order to make the statements not misleading under the Securities Act or any other statute or the common law. However, each Fund does agree to indemnify Invesco Distributors or hold it harmless to the extent that the statement or omission was made in reliance upon, and in conformity with, information furnished to it by or on behalf of Invesco Distributors. In no case:

•

is the indemnity of each Fund in favor of Invesco Distributors or any person indemnified to be deemed to protect Invesco Distributors or any person against any liability to each Fund or its security holders to which Invesco Distributors or such person would otherwise be subject by reason of willful misfeasance, bad faith or negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under the Distribution Services Agreement; or

113

•

is any Fund to be liable under its indemnity agreement with respect to any claim made against Invesco Distributors or any person indemnified unless Invesco Distributors or such person, as the case may be, will have notified the applicable Fund in writing of the claim promptly after the summons or other first written notification giving information of the nature of the claims will have been served upon Invesco Distributors or any such person (or after Invesco Distributors or such person will have received notice of service on any designated agent).

However, failure to notify each Fund of any claim will not relieve each Fund from any liability which it may have to any person against whom such action is brought otherwise than on account of its indemnity agreement described herein. Each Fund will be entitled to participate at its own expense in the defense, or, if it so elects, to assume the defense of any suit brought to enforce any claims, and if any Fund elects to assume the defense, the defense will be conducted by counsel chosen by such Fund. In the event any Fund elects to assume the defense of any suit and retain counsel, Invesco Distributors, its officers or directors or controlling person(s) or defendant(s) in the suit, will bear the fees and expenses of any additional counsel retained by them. If no Fund elects to assume the defense of any suit, it will reimburse Invesco Distributors, its officers or directors or controlling person(s) or defendant(s) in the suit for the reasonable fees and expenses of any counsel retained by them. Each Fund agrees to notify Invesco Distributors promptly of the commencement of any litigation or proceeding against it or any of its officers in connection with the issuance or sale of any of the Shares.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion describes the material U.S. federal (and certain state and local) income tax considerations associated with the purchase, ownership and disposition of Shares as of the date hereof by U.S. Shareholders (as defined below) andnon-U.S. Shareholders (as defined below). Except where noted, this discussion deals only with Shares held as capital assets by Shareholders who acquired

Shares by purchase and does not address special situations, such as those of:

•

dealers in securities, commodities or currencies;

•

financial institutions;

•

regulated investment companies (“RICs”), other than the status of the Funds as qualified publicly traded partnerships (“qualified PTPs”) within the meaning of the Code;

•

real estate investment trusts;

•

tax-exempt organizations;

•

insurance companies;

•

persons holding Shares as a part of a hedging, integrated or conversion transaction or a straddle;

•

traders in securities or commodities that elect to use amark-to-market method of accounting for their securities or commodities holdings; or

•

persons liable for federal alternative minimum tax.

Furthermore, the discussion below is based upon the provisions of the Code, the Treasury Regulations promulgated thereunder, and administrative and judicial interpretations thereof, all as of the date hereof, and such authorities may be repealed, revoked, modified or subject to differing interpretations, possibly on a retroactive basis, so as to result in U.S. federal income tax consequences different from those described below, which may adversely affect a Fund and/or its shareholders.

The Tax Cuts and Jobs Act (the “Tax Act”) makes significant changes to the U.S. federal income tax rules for taxation of individuals and corporations, generally effective for taxable years beginning after December 31, 2017. Most of the changes applicable to individuals are temporary and would apply only to taxable years beginning after December 31, 2017 and before January 1, 2026. The Tax Act makes numerous changes to the tax rules that may affect shareholders and may indirectly affect the Funds. You should consult your tax advisor for specific guidance regarding the impact of the Tax Act on the tax effects of your investment in a Fund.

114

A “U.S. Shareholder” means a beneficial owner of Shares that is for U.S. federal income tax purposes:

•

an individual citizen or resident of the United States;

•

a corporation (or other entity taxable as a corporation) created or organized in or under the laws of the United States or any state thereof or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of such trust or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

A“non-U.S. Shareholder” means a beneficial owner of Shares that is not a U.S. Shareholder.

If a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Shares, the tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner in a partnership holding Shares, we urge you to consult your own tax advisor.

No statutory, administrative or judicial authority directly addresses the treatment of Shares or instruments similar to Shares for U.S. federal income tax purposes. As a result, we cannot assure you that the IRS or the courts will agree with the tax consequences described herein. A different treatment from that described below could adversely affect the amount, timing and character of items of income, gain, loss or deduction in respect of an investment in the Shares. If you are considering the purchase of Shares, we urge you to consult your own tax advisor concerning the particular U.S. federal income tax consequences to you of the purchase, ownership and disposition of Shares, as well as any consequences to you arising under the laws of any other taxing jurisdiction.

Status of the Funds

Under current law and assuming full compliance with the terms of the Trust Agreement and applicable law (and other relevant documents), in the opinion of Morgan, Lewis & Bockius LLP, each of the Funds will be classified as a partnership for U.S. federal income tax purposes. Accordingly, subject to the discussion below regarding publicly traded partnerships, each of the Funds generally will not be a taxable entity for U.S. federal income tax purposes and each of the Funds will not incur U.S. federal income tax liability.

The opinion of Morgan, Lewis & Bockius LLP is based on various assumptions relating to each Fund’s organization, operation, assets and activities, including assumptions that a Fund will not invest in any assets except those specifically provided for currently in this Prospectus, and that neither the Trust Agreement nor any other relevant document will be otherwise amended. The opinion of Morgan, Lewis & Bockius LLP further assumes that all factual representations and statements set forth in all relevant documents, records, and instruments are true and correct, all actions described in this Prospectus are completed in a timely fashion and that a Fund will at all times operate in accordance with the method of operation described in the Trust Agreement and this Prospectus, and is conditioned upon factual representations and covenants made by a Fund and the Managing Owner regarding the Fund’s organization, operation, assets, activities and the conduct of the Fund’s operations, and assumes that such representations and covenants are accurate and complete.

Special Rules for Publicly Traded Partnerships

A partnership generally is not a taxable entity and generally incurs no U.S. federal income tax liability. Section 7704 of the Code provides that publicly traded partnerships will, as a general rule, be taxed as corporations. However, an exception exists with respect to publicly traded partnerships of which 90% or more of the gross income during each taxable year consists of “qualifying income” within the meaning of Section 7704(d) of the Code, or the qualifying income exception. Qualifying income includes dividends, interest, capital gains from the

115

sale or other disposition of stocks and debt instruments and, in the case of a partnership (such as each Fund) a principal activity of which is the buying and selling of commodities or futures contracts with respect to commodities, income and gains derived from commodities or futures contracts with respect to commodities. Each Fund anticipates that at least 90% of its gross income for each taxable year will constitute qualifying income within the meaning of Section 7704(d) of the Code.

There can be no assurance that the IRS will not assert that a Fund should be treated as a publicly traded partnership taxable as a corporation. No ruling has been or will be sought from the IRS, and the IRS has made no determination as to the status of any Fund for U.S. federal income tax purposes or whether any Fund’s operations generate “qualifying income” under Section 7704(d) of the Code. Whether a Fund will continue to meet the qualifying income exception is a matter that will be determined by the Fund’s operations and the facts existing at the time of future determinations. However, the Managing Owner will use its best efforts to cause each Fund to operate in such manner as is necessary for the Fund to continue to meet the qualifying income exception.

If a Fund were taxable as a corporation in any taxable year, either as a result of a failure to meet the qualifying income exception described above or otherwise, the Fund’s items of income, gain, loss and deduction would be reflected only on the Fund’s tax return rather than being passed through to the Shareholders, and the Fund’s net income would be taxed to it at the income tax rates applicable to domestic corporations. In addition, if a Fund were taxable as a corporation, any distribution made by the Fund to a Shareholder would be treated as taxable dividend income, to the extent of the Fund’s current or accumulated earnings and profits, or, in the absence of current and accumulated earnings and profits, as a nontaxable return of capital to the extent of the Shareholder’s tax basis in its Shares, or as taxable capital gain, after the Shareholder’s tax basis in its Shares is reduced to zero. Taxation of a Fund as a corporation could result in a material reduction in a Shareholder’s cash flow andafter-tax return and thus could result in a substantial reduction of the value of the Shares.

The discussion below is based on Morgan, Lewis & Bockius LLP’s opinion that each of the

Funds will be classified as a partnership for U.S. federal income tax purposes that is not subject to corporate income tax for U.S. federal income tax purposes.

U.S. Shareholders

Treatment of Fund Income

A partnership generally does not incur U.S. federal income tax liability. Instead, each partner of a partnership is required to take into account its share of items of income, gain, loss, deduction and other items of the partnership. Accordingly, each Shareholder in a Fund will be required to include in income its allocable share of the Fund’s income, gain, loss, deduction and other items for the Fund’s taxable year ending with or within its taxable year. In computing a partner’s U.S. federal income tax liability, the items must be included, regardless of whether cash distributions are made by the partnership. Thus, Shareholders may be required to take into account taxable income without a corresponding current receipt of cash if the Fund generates taxable income but does not make cash distributions in an amount equal to the taxable income, or if the Shareholder is not able to deduct, in whole or in part, the Shareholder’s allocable share of the Fund’s expenses or capital losses. Each Fund’s taxable year will end on December 31 unless otherwise required by law. Each Fund will use the accrual method of accounting.

In the case ofnon-corporate shareholders, the Tax Act establishes for taxable years beginning after December 31, 2017 and before January 1, 2026 a 20% deduction for “qualified publicly traded partnership income” within the meaning of new Section 199A(e)(5) of the Code. Qualified publicly traded partnership income includes a Fund’s income effectively connected with the Fund’s trade or business, but does not include certain investment income. In light of the very recent enactment of the new rules regarding the deduction, the lack of guidance interpreting such rules, and the expected character of the income of the Funds, it is unclear whether any of a Fund’s income will be eligible for the deduction. Potential investors should consult their tax advisors regarding the availability of such deduction for their allocable share of a Fund’s items of income, gain, deduction and loss.

116

Shareholders will take into account their respective shares of ordinary income realized by the Fund from accruals of interest on United States Treasury Securities, orT-Bills, held in the Fund’s portfolio. Each Fund may holdT-Bills or other debt instruments with “acquisition discount” or “original issue discount”, in which case Shareholders will be required to include accrued amounts in taxable income on a current basis even though receipt of those amounts may occur in a subsequent year. Each Fund may also acquire debt instruments with “market discount.” Under rules prior to the Tax Act, upon disposition of such obligations, gain will generally be required to be treated as interest income to the extent of the market discount and Shareholders in the Fund will be required to include as ordinary income their share of the market discount that accrued during the period the obligations were held by the Fund. Certain changes made in the Tax Act regarding accounting methods may require an earlier accrual of market discount. The effect of these changes are uncertain and shareholders should consult their tax advisors with respect to whether they are required to accrue market discount. Shareholders will take into account their respective shares of any dividends received by a Fund from such Fund’s investment in the money market mutual funds and certainT-Bill ETFs.

With the exception of futures on Aluminum, Zinc and Copper – Grade A, traded by DB Base Metals Fund, it is expected that a substantial portion of the futures on the Index Commodities held by the Funds will constitute Section 1256 Contracts (as defined below) (see “Special Notice for Investors in PowerShares DB Base Metals Fund” below). The Code generally applies a“mark-to-market” system of taxing unrealized gains and losses on and otherwise provides for special rules of taxation with respect to futures and other contracts that are Section 1256 Contracts. Section 1256 Contracts held by the Funds at the end of a taxable year of the Funds will be treated for U.S. federal income tax purposes as if they were sold by the Funds at their fair market value on the last business day of the taxable year. The net gain or loss, if any, resulting from these deemed sales (known as“marking-to-market”), together with any gain or loss resulting from any actual sales of Section 1256 Contracts (or other termination of a Fund’s obligations under such contracts), must be taken into account by the Fund in computing its taxable income for the year. If a Section 1256 Contract held by a Fund at the end of a taxable year

is sold in the following year, the amount of any gain or loss realized on the sale will be adjusted to reflect the gain or loss previously taken into account under themark-to-market rules.

Capital gains and losses from Section 1256 Contracts generally are characterized as short-term capital gains or losses to the extent of 40% of the gains or losses and as long-term capital gains or losses to the extent of 60% of the gains or losses. Thus, Shareholders of a Fund will generally take into account their pro rata share of the long-term capital gains and losses and short-term capital gains and losses from Section 1256 Contracts held by the Fund and taken into account by the Fund in computing its taxable income. If anon-corporate taxpayer incurs a net capital loss for a year, the portion of the loss, if any, which consists of a net loss on Section 1256 Contracts may, at the election of the taxpayer, be carried back three years. A loss carried back to a year by anon-corporate taxpayer may be deducted only to the extent (1) the loss does not exceed the net gain on Section 1256 Contracts for the year and (2) the allowance of the carryback does not increase or produce a net operating loss for the year.

Any futures contracts on Index Commodities held by a Fund that are not classified as Section 1256 Contracts will not be subject to the year end“mark-to-market” rules of Section 1256, as described above. Accordingly, any long-term or short-term capital gains or losses with respect to such futures held by a Fund that are not classified as Section 1256 Contracts will only be recognized by the Fund when such futures positions are assigned or closed (by offset or otherwise). The applicable holding period for qualification for long-term capital gain or loss treatment for the commodity futures held by a Fund that are not Section 1256 Contracts is more than one year.

Special Notice for Investors in PowerShares DB Base Metals Fund

Prospective investors in PowerShares DB Base Metals Fund should be aware that this Fund does not invest in Section 1256 Contracts when tracking theDBIQ-OY Industrial Metals ER™. As a result, all gains or losses will be characterized as short-term or long-term capital gains or losses rather than being characterized as a mixture of short-term and long-term capital gains or losses as applicable to the other

117

Funds that invest in Section 1256 Contracts. The applicable holding period for qualification for long-term capital gain or loss treatment for such futures held by the PowerShares DB Base Metals Fund that are not Section 1256 Contracts is more than one year. In addition, since such futures are not subject to the year end“mark-to-market” rules of Section 1256 described above, long-term or short-term capital gains and losses will only be recognized by the Fund when such futures positions are assigned or closed (by offset or otherwise).

Allocation of the Funds’ Profits and Losses

For U.S. federal income tax purposes, a Shareholder’s distributive share of a Fund’s income, gain, loss, deduction and other items will be determined by the Trust Agreement, unless an allocation under such agreement does not have “substantial economic effect,” in which case the allocations will be determined in accordance with the “partners’ interests in the partnership.” Subject to the discussion below under “Monthly Allocation and Revaluation Conventions and Transferor/Transferee Allocations” and “Section 754 Election,” the allocations pursuant to the Trust Agreement should be considered to have substantial economic effect or deemed to be made in accordance with the partners’ interests in the Fund.

If the allocations provided by the Trust Agreement were successfully challenged by the IRS, the amount of income or loss allocated to Shareholders for U.S. federal income tax purposes under the Trust Agreement could be increased or reduced or the character of the income or loss could be modified or both.

As described in more detail below, the U.S. federal income tax rules that apply to partnerships are complex and their application is not always clear. The rules generally were not written for, and in some respects are difficult to apply to, publicly traded partnerships. Each Fund will apply certain assumptions and conventions intended to comply with the intent of the rules and to report income, gain, loss, deduction and credit to Shareholders in a manner that reflects the economic gains and losses, but these assumptions and conventions may not comply with all aspects of the applicable Treasury Regulations. It is possible therefore that the IRS will

successfully assert that assumptions made and/or conventions used do not satisfy the technical requirements of the Code or the Treasury Regulations and will require that tax items be adjusted or reallocated in a manner that could adversely impact Shareholders.

Monthly Allocation and Revaluation Conventions and Transferor/Transferee Allocations

In general, each Fund’s taxable income and losses will be determined monthly and will be apportioned among the Shareholders of such Fund in proportion to the number of Shares owned by each of them as of the close of the last trading day of the preceding month. By investing in Shares, a U.S. Shareholder agrees that, in the absence of an administrative determination or judicial ruling to the contrary, it will report income and loss under the monthly allocation and revaluation conventions described below.

Under the monthly allocation convention, whomever is treated for U.S. federal income tax purposes as holding Shares as of the close of the last trading day of the preceding month will be treated as continuing to hold the Shares until immediately before the close of the last trading day of the following month. With respect to any Shares that were not treated as outstanding as of the close of the last trading day of the preceding month, the first person that is treated as holding such Shares (other than an underwriter or other person holding in a similar capacity) for U.S. federal income tax purposes will be treated as holding such Shares for this purpose as of the close of the last trading day of the preceding month. As a result, a Shareholder who has disposed of Shares prior to the close of the last trading day of a month may be allocated items of income, gain, loss and deduction realized after the date of transfer.

Section 706 of the Code generally requires that items of partnership income and deductions be allocated between transferors and transferees of partnership interests on a daily basis. It is possible that transfers of Shares could be considered to occur for U.S. federal income tax purposes when the transfer is completed without regard to a Fund’s monthly convention for allocating income and deductions. If this were to occur, the Fund’s

118

allocation method might be considered a monthly convention that does not literally comply with that requirement. If the IRS treats transfers of Shares as occurring throughout each month and a monthly convention is not allowed by the Treasury Regulations (or only applies to transfers of less than all of a Shareholder’s Shares) or if the IRS otherwise does not accept a Fund’s convention, the IRS may contend that taxable income or losses of the Fund must be reallocated among the Shareholders. If such a contention was sustained, the Shareholders’ respective tax liabilities would be adjusted to the possible detriment of certain Shareholders. The Managing Owner is authorized to revise the Funds’ methods of allocation between transferors and transferees (as well as among Shareholders whose interests otherwise vary during a taxable period).

In addition, for any month in which a creation or redemption of Shares takes place, a Fund generally will credit or debit, respectively, the “book” capital accounts of the existing Shareholders with any unrealized gain or loss in the Fund’s assets. This will result in the allocation of a Fund’s items of income, gain, loss, deduction and credit to existing Shareholders to account for the difference between the tax basis and fair market value of property owned by the Fund at the time new Shares are issued or old Shares are redeemed, or reverse Section 704(c) allocations. The intended effect of these allocations is to allocate anybuilt-in gain or loss in a Fund’s assets at the time of a creation or redemption of Shares to the investors that economically have earned such gain or loss.

As with the other allocations described above, each Fund generally will use a monthly convention for purposes of the reverse Section 704(c) allocations. More specifically, each Fund generally will credit or debit, respectively, the “book” capital accounts of existing Shareholders with any unrealized gain or loss in the Fund’s assets based on a calculation utilizing the average price of the corresponding Fund’s Shares during the month in which the creation or redemption transaction takes place, rather than the fair market value of its assets at the time of such creation or redemption, or the revaluation convention. As a result, it is possible that, for U.S. federal income tax purposes, (i) a purchaser of newly issued Shares will be allocated some or all of the unrealized gain in the Fund’s assets at the time it acquires the Shares or (ii) an existing Shareholder

will not be allocated its entire share in the unrealized loss in the Fund’s assets at the time of such acquisition. Furthermore, the applicable Treasury Regulations generally require that the “book” capital accounts be adjusted based on the fair market value of partnership property on the date of adjustment and do not explicitly allow the adoption of a monthly revaluation convention.

The Code and applicable Treasury Regulations generally require that items of partnership income and deductions be allocated between transferors and transferees of partnership interests on a daily basis, and that adjustments to “book” capital accounts be made based on the fair market value of partnership property on the date of adjustment. The Code and Treasury Regulations do not contemplate monthly allocation or revaluation conventions. If the IRS does not accept a Fund’s monthly allocation or revaluation convention, the IRS may contend that taxable income or losses of the Fund must be reallocated among the Shareholders of the Fund. If such a contention were sustained, the Shareholders’ respective tax liabilities would be adjusted to the possible detriment of certain Shareholders. The Managing Owner is authorized to revise the Fund’s allocation and revaluation methods in order to comply with applicable law or to allocate items of partnership income and deductions in a manner that reflects more accurately the Shareholders’ interests in the Fund.

Section 754 Election

Each Fund has made the election permitted by Section 754 of the Code. Such an election, once made, is irrevocable without the consent of the IRS. The making of the Section 754 election by a Fund will generally have the effect of requiring a purchaser of Shares to adjust its proportionate share of the basis in the Fund’s assets, or the inside basis, pursuant to Section 743(b) of the Code to fair market value (as reflected in the purchase price for the purchaser’s Shares), as if it had acquired a direct interest in the Fund’s assets. The Section 743(b) adjustment is attributed solely to a purchaser of Shares and is not added to the bases of the Fund’s assets associated with all of the other Shareholders in the Fund. Depending on the relationship between a Shareholder’s purchase price for Shares and its unadjusted share of the Fund’s inside basis at the time of the purchase, the Section 754 election may be either advantageous or disadvantageous to the

119

Shareholder as compared to the amount of gain or loss a Shareholder would be allocated absent the Section 754 election.

The calculations under Section 754 of the Code are complex, and there is little legal authority concerning the mechanics of the calculations, particularly in the context of publicly traded partnerships. To help reduce the complexity of those calculations and the resulting administrative costs, each Fund will apply certain conventions in determining and allocating the Section 743 basis adjustments. It is possible that the IRS will successfully assert that some or all of such conventions utilized by a Fund do not satisfy the technical requirements of the Code or the Treasury Regulations and, thus, will require different basis adjustments to be made. If the IRS were to sustain such a position, a Shareholder may have adverse tax consequences.

In order to make the basis adjustments permitted by Section 754, each Fund will be required to obtain information regarding each Shareholder’s secondary market transactions in Shares as well as creations and redemptions of Shares. Each Fund will seek the requested information from the record Shareholders, and, by purchasing Shares, each beneficial owner of Shares will be deemed to have consented to the provision of the information by the record owner of the beneficial owner’s Shares. Notwithstanding the foregoing, however, there can be no guarantee that any Fund will be able to obtain such information from record owners or other sources, or that the basis adjustments that any Fund makes based on the information it is able to obtain will be effective in eliminating disparity between a Shareholder’s outside basis in its Shares and its interest in the inside basis in the Fund’s assets.

Constructive Termination

A Fund will experience a constructive termination for tax purposes if there is a sale or exchange of 50 percent or more of the total Shares in the Fund within a 1twelve-month period. A constructive termination results in the closing of a Fund’s taxable year for all Shareholders in the Fund. In the case of a Shareholder reporting on a taxable year other than the taxable year used by a Fund (which is a fiscal year ending December 31), the early closing of the Fund’s taxable year may result in

more than twelve months of its taxable income or loss being includable in the Shareholder’s taxable income for the year of termination. The Fund would be required to make new tax elections after a termination, including a new election under Section 754. A termination could also result in penalties if a Fund were unable to determine that the termination had occurred.

Treatment of Distributions

Distributions of cash by a partnership are generally not taxable to the distributee to the extent the amount of cash does not exceed the distributee’s tax basis in its partnership interest. Thus, any cash distributions made by a Fund will be taxable to a Shareholder only to the extent the distributions exceed the Shareholder’s tax basis in the Shares it is treated as owning (see “Tax Basis in Fund Shares” below). Any cash distributions in excess of a Shareholder’s tax basis generally will be considered to be gain from the sale or exchange of the Shares (see “Disposition of Shares” below).

Creation and Redemption of Shares

Shareholders, other than Authorized Participants (or holders for which an Authorized Participant is acting), generally will not recognize gain or loss as a result of an Authorized Participant’s creation or redemption of a Basket. If a Fund disposes of assets in connection with the redemption of a Basket, however, the disposition may give rise to gain or loss that will be allocated to Shareholders. An Authorized Participant’s creation or redemption of a Basket also may affect a Shareholder’s share of a Fund’s tax basis in its assets, which could affect the amount of gain or loss allocated to the Shareholder on the sale or disposition of portfolio assets by the Fund.

Disposition of Shares

If a U.S. Shareholder transfers Shares of a Fund and such transfer is a sale or other taxable disposition, the U.S. Shareholder will generally be required to recognize gain or loss measured by the difference between the amount realized on the sale and the U.S. Shareholder’s adjusted tax basis in the Shares sold. The amount realized will include an amount equal to the U.S. Shareholder’s share of the Fund’s liabilities, as well as any proceeds from the sale. The gain or loss recognized will generally be

120

taxable as capital gain or loss. Capital gain ofnon-corporate U.S. Shareholders is eligible to be taxed at reduced rates where the Shares sold are considered held for more than one year. Capital gain of corporate U.S. Shareholders is taxed at the same rate as ordinary income. Any capital loss recognized by a U.S. Shareholder on a sale of Shares will generally be deductible only against capital gains, except that anon-corporate U.S. Shareholder may also offset up to $3,000 per year of ordinary income with capital losses.

U.S. Shareholders whose Shares are loaned to a “short seller” to cover a short sale of Shares may be considered as having disposed of those Shares. If so, such Shareholder would no longer be a beneficial owner of those Shares during the period of the loan and may recognize gain or loss from the disposition. As a result, during the period of the loan, (1) any of a Fund’s income, gain, loss, deduction, or other items with respect to those Shares would not be reported by the Shareholder, and (2) any cash distributions received by the Shareholder as to those Shares could be fully taxable, likely as ordinary income. Accordingly, Shareholders who desire to avoid the risk of income recognition from a loan of their Shares to a short seller are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their Shares. These rules, however, should not affect the amount or timing of income, gain, deduction or loss reported by a taxpayer that is a dealer in securities that marks the Shares to market for U.S. federal income tax purposes, or a trader in securities that has elected to use themark-to-market method of tax accounting with respect to the Shares.

Tax Basis in Fund Shares

A U.S. Shareholder’s initial tax basis in its Shares will equal the sum of (a) the amount of cash paid by the U.S. Shareholder for its Shares and (b) the U.S. Shareholder’s share of the Fund’s liabilities. A U.S. Shareholder’s tax basis in its Shares will be increased by (a) the U.S. Shareholder’s share of the Fund’s taxable income, including capital gain, (b) the U.S. Shareholder’s share of the Fund’s income, if any, that is exempt from tax and (c) any increase in the U.S. Shareholder’s share of the Fund’s liabilities. A U.S. Shareholder’s tax basis in Shares will be decreased (but not below zero) by (a) the amount of any cash

distributed (or deemed distributed) to the U.S. Shareholder, (b) the U.S. Shareholder’s share of the Fund’s losses and deductions, (c) the U.S. Shareholder’s share of the Fund’s expenditures that are neither deductible nor properly chargeable to its capital account and (d) any decrease in the U.S. Shareholder’s share of the Fund’s liabilities.

Limitations on Interest Deductions

The deductibility of anon-corporate U.S. Shareholder’s “investment interest expense” is generally limited to the amount of the Shareholder’s “net investment income.” Investment interest expense will generally include interest expense incurred by a Fund, if any, and investment interest expense incurred by the U.S. Shareholder on any margin account borrowing or other loan incurred to purchase or carry Shares. Net investment income includes gross income from property held for investment and amounts treated as portfolio income, such as dividends and interest, less deductible expenses, other than interest, directly connected with the production of investment income. For this purpose, any long-term capital gain or qualifying dividend income that is taxable at long-term capital gains rates is excluded from net investment income unless the U.S. Shareholder elects to pay tax on such capital gain or dividend income at ordinary income rates.

Organization, Syndication and Other Expenses

In general, for taxable years beginning before January 1, 2018, expenses incurred that are considered “miscellaneous itemized deductions” may be deducted by a U.S. Shareholder that is an individual, estate or trust only to the extent that they exceed 2% of the adjusted gross income of the U.S. Shareholder. The Code imposes additional limitations on the amount of certain itemized deductions allowable to individuals, by reducing the otherwise allowable portion of such deductions by an amount equal to the lesser of:

•

3% of the individual’s adjusted gross income in excess of certain threshold amounts; or

•

80% of the amount of certain itemized deductions otherwise allowable for the taxable year.

Under the Tax Act, “miscellaneous itemized deductions” are not permitted for taxable years beginning after December 31, 2017 and before January 1, 2026.

121

In addition, these expenses are also not deductible in determining the alternative minimum tax liability of anon-corporate U.S. Shareholder. Each Fund will report its expenses on a pro rata basis to the Shareholders, and each U.S. Shareholder will determine separately to what extent they are deductible on the U.S. Shareholder’s tax return. A U.S. Shareholder’s inability to deduct all or a portion of the expenses could result in an amount of taxable income to the U.S. Shareholder with respect to the Fund that exceeds the amount of cash actually distributed to such U.S. Shareholder for the year. It is anticipated that management fees each Fund will pay will constitute miscellaneous itemized deductions.

Under Section 709(b) of the Code, amounts paid or incurred to organize a partnership may, at the election of the partnership, be treated as deferred expenses, which are allowed as a deduction ratably over a period of 180 months. Each of the Funds has made a Section 709(b) election. Expenditures in connection with the issuance and marketing of Shares (so called “syndication fees”) are not eligible for the180-month amortization provision and are not deductible.

Passive Activity Income and Loss

Individuals are subject to certain “passive activity loss” rules under Section 469 of the Code. Under these rules, losses from a passive activity generally may not be used to offset income derived from any source other than passive activities. Losses that cannot be currently used under this rule may generally be carried forward. Upon an individual’s disposition of an interest in the passive activity, the individual’s unused passive losses may generally be used to offset other (i.e.,non-passive) income. Under current Treasury Regulations, income or loss from a Fund’s investments generally will not constitute income or losses from a passive activity. Therefore, income or loss realized by Shareholders of a Fund will not be available to offset a U.S. Shareholder’s passive losses or passive income from other sources.

Tax on Net Investment Income

A 3.8% tax will be imposed on some or all of the net investment income of certain individuals with modified adjusted gross income of over $200,000 ($250,000 in the case of joint filers) and the undistributed net investment income of certain

estates and trusts. For these purposes, it is expected that all or a substantial portion of a Shareholder’s share of Fund income will be net investment income. In addition, certain Fund expenses may not be deducted in calculating a Shareholder’s net investment income.

Reporting by each Fund to its Shareholders

Each Fund will file a partnership tax return. Accordingly, tax information will be provided to Shareholders on ScheduleK-1 for each calendar year as soon as practicable after the end of such taxable year but in no event later than March 15. Each ScheduleK-1 provided to a Shareholder will set forth the Shareholder’s share of the Fund’s tax items (i.e., interest income fromT-Bills, short-term and long-term capital gain or loss with respect to the futures contracts, Money Market Income,T-Bill ETF Income and investment expenses for the year) in a manner sufficient for a U.S. Shareholder to complete its tax return with respect to its investment in the Shares.

Each Shareholder, by its acquisition of Shares of a Fund, will be deemed to agree to allow brokers and nominees to provide to the Fund its name and address and the other information and forms as may be reasonably requested by the Fund for purposes of complying with their tax reporting and withholding obligations (and to waive any confidentiality rights with respect to the information and forms for this purpose) and to provide information or forms upon request.

Given the lack of authority addressing structures similar to that of the Funds, it is not certain that the IRS will agree with the manner in which tax reporting by the Funds will be undertaken. Therefore, Shareholders should be aware that future IRS interpretations or revisions to Treasury Regulations could alter the manner in which tax reporting by the Funds and any nominee will be undertaken.

Tax Agent

The beneficial owners who are of a type, as identified by the nominee through whom their Shares are held, that do not ordinarily have U.S. federal tax return filing requirements (collectively, “CertainK-1 Unitholders”), have designated the Managing Owner as their tax agent (the “Tax Agent”) in dealing with the Trust. In light of such designation and pursuant to

122

Treasury Regulation section1.6031(b)-1T(c), as amended from time to time, the Trust will provide to the Tax Agent CertainK-1 Unitholders’ statements (as such term is defined under Treasury Regulation section1.6031(b)-1T(a)(3)), as amended from time to time).

Audits and Adjustments to Tax Liability

Pursuant to the governing documents, the Managing Owner has been appointed the “partnership representative” of each Fund to act on its behalf in connection with IRS audits and related proceedings.

Under the new regime for the U.S. federal income tax audit of partnerships, the partnership representative’s actions, including the partnership representative’s agreement to adjustments of a Fund’s income in settlement of an IRS audit of the Fund, will bind all Shareholders, andopt-out rights available to certain Shareholders in connection with certain actions of the tax matters partner under the partnership audit rules in effect prior to January 1, 2018 will no longer be available.

The new partnership audit rules are effective for federal income tax returns filed for taxable years of the Fund beginning on or after January 1, 2018, but may apply for returns filed for the 2016 or 2017 taxable years, if elected. For returns filed for taxable years prior to the effective date of the new rules, the existing partnership rules will apply. Depending on subsequent IRS guidance and facts and circumstances, the Managing Owner may choose to elect early application of the new partnership audit rules to the Fund, if such an election is then available.

Under the new rules, Shareholders will not be required to receive notice of any audit of a Fund tax return and will not be entitled to participate in any such audit, and any adjustment made in a Fund audit will be binding on all of the Shareholders. Any tax arising from an audit of a Fund tax return, as well as any resulting interest and penalties, will generally be payable by the Fund in the year in which the determination becomes final unless the Fund elects to send statements (“Adjustment Statements”) to its Shareholders for the audited year informing them of their shares of the adjustments made on audit. If a Fund sends Adjustment Statements, Shareholders will generally be required to pay any tax, interest and

penalties arising from such adjustments as if the adjustments were made in the audited year and any other affected year, as applicable, but will not be required to amend their tax returns for any prior year. In general, if a Fund pays the tax resulting from the adjustment, the amount will be determined by applying the highest rate of tax in effect for the audited year to the net adjustment amount, subject to possible reduction, with the approval of the IRS, to account for certain types of income and fortax-exempt Shareholders. Proposed Treasury Regulations provide guidance as to how the tax will be paid if a partnership or other flow-through entity receives an Adjustment Statement from a lower-tier partnership in which it holds an interest, but until such Treasury Regulations are finalized the application of the new rules to such tiered structures remains unclear. There are likely to be clarifications and other changes to the new rules, through Treasury regulations, other IRS guidance and possibly legislation. It is also possible that state and local taxing jurisdictions will enact similar provisions.

Shareholders should discuss with their own tax advisors the possible implications of the new rules with respect to an investment in a Fund.

Non-U.S. Shareholders

Each of the Funds will conduct its activities in such a manner that anon-U.S. Shareholder who is not otherwise carrying on a trade or business in the United States will not be considered to be engaged in a trade or business in the United States as a result of an investment in the Shares of a Fund. Anon-U.S. Shareholder’s share of the interest income realized by a Fund on its holdings ofT-Bills will be exempt from U.S. withholding tax provided thenon-U.S. Shareholder certifies on IRS FormW-8BEN or IRS FormW-8BEN-E (or other applicable form) that the Shareholder is not a U.S. person, provides name and address information and otherwise satisfies applicable documentation and certification requirements. In addition, with respect to certain distributions made tonon-U.S. Shareholders, no withholding is required and the distributions by the Funds that relate to dividends paid to the Funds by money market mutual funds andT-Bill ETFs that are RICs generally will not be subject to federal income tax if (i) the distributions are properly reported by us as “interest-related dividends” or “short-term capital gain dividends,” (ii) the distributions are derived

123

from sources specified in the Code for such dividends and (iii) certain other requirements are satisfied. No assurance can be given that any of our distributions would be designated as eligible for this exemption.

Non-U.S. Shareholders will not be subject to U.S. federal income tax on gains realized on the sale of Shares of a Fund or on thenon-U.S. Shareholder’s share of the Fund’s capital gains. However, the Tax Act requires the purchaser or transferee of a partnership interest to withhold a 10% tax on the “amount realized” by aNon-U.S. Shareholder on the sale or exchange of Shares. The IRS, however, has temporarily suspended the 10% withholding requirement on sales of certain publicly traded partnership interests by foreign persons until it has a chance to issue Treasury Regulations. Each Fund believes that it is a publicly traded partnership for purposes of these rules and is eligible for the temporary suspension of these withholding provisions. It is unclear how this withholding requirement will be instituted in the future and will be governed by yet to be drafted IRS guidance.Non-U.S. Shareholders, however, should expect that this withholding requirement will be in effect at some point in the near future. ANon-U.S. Shareholder also could be liable for state/local income taxes, and could have corresponding state/local tax filing requirements.

In the case of an individualnon-U.S. Shareholder, thenon-U.S. Shareholder will be subject to U.S. federal income tax on gains on the sale of Shares or thenon-U.S. Shareholder’s distributive share of capital gains if thenon-U.S. Shareholder is present in the United States for 183 days or more during a taxable year and certain other conditions are met.

Non-U.S. Shareholders that are individuals will be subject to U.S. federal estate tax on the value of U.S. situs property owned at the time of their death (unless a statutory exemption or tax treaty exemption applies). It is unclear whether partnership interests (such as the Shares of a Fund) will be considered U.S. situs property. Accordingly,non-U.S. Shareholders may be subject to U.S. federal estate tax on all or part of the value of the Shares owned at the time of their death.

Non-U.S. Shareholders are advised to consult their own tax advisors with respect to the particular tax consequences to them of an investment in the Shares.

Regulated Investment Companies

RICs may invest up to 25% of their assets in qualified PTPs and net income derived from such investments is qualifying income under the income source test applicable to entities seeking to qualify for the special tax treatment available to RICs under the Code. In addition, interests in a qualified PTP are treated as issued by such PTP. A RIC will also be required to look through corporations in which the RIC owns a 20% or more voting stock interest in determining whether a RIC has invested up to 25% of its assets in “qualified PTPs,” including other issuers, when testing compliance with the asset diversification tests applicable to RICs under the Code. Each Fund anticipates that it will qualify as a qualified PTP for any taxable year in which the Fund realizes sufficient gross income from its commodity futures transactions. However, qualification of a Fund as a qualified PTP depends on performance of the Fund for the particular tax year and there is no assurance that it will qualify in a given year or that future results of the Fund will conform to prior experience. In addition, there is, to date, no regulatory guidance on the application of these rules, and it is possible that future guidance may adversely affect qualification of a Fund as a qualified PTP. In a 2006 revenue ruling, the IRS clarified that derivative contracts owned by a RIC that provide for a total-return exposure on an Index Commodity will not produce qualifying income for purposes of the RIC qualification rules. The IRS interpretation set forth in such ruling, however, does not adversely affect the Funds’ ability to be treated as a qualified PTP for purposes of applying the RIC qualification rules. RIC investors are urged to monitor their investment in the Fund and consult with a tax advisor concerning the impact of such an investment on their compliance with the income source and asset diversification requirements applicable to RICs. Each Fund will make available on the Managing Owner’s website periodic tax information designed to enable RIC investors in its Shares to make a determination as to the Fund’s status under the qualified PTP rules.

Tax-Exempt Organizations

An organization that is otherwise exempt from U.S. federal income tax is nonetheless subject to taxation with respect to its “unrelated business taxable income” (“UBTI”). Except as noted below with respect to certain categories of exempt income, UBTI generally includes income or gain derived

124

(either directly or through a partnership) from a trade or business, the conduct of which is substantially unrelated to the exercise or performance of the organization’s exempt purpose or function.

UBTI generally does not include passive investment income, such as dividends, interest and capital gains, whether realized by the organization directly or indirectly through a partnership (such as a Fund) in which it is a partner. This type of income is exempt, subject to the discussion of “unrelated debt-financed income” below, even if it is realized from securities trading activity that constitutes a trade or business.

UBTI includes not only trade or business income or gain as described above, but also “unrelated debt-financed income.” This latter type of income generally consists of (1) income derived by an exempt organization (directly or through a partnership) from income producing property with respect to which there is “acquisition indebtedness” at any time during the taxable year and (2) gains derived by an exempt organization (directly or through a partnership) from the disposition of property with respect to which there is acquisition indebtedness at any time during the twelve-month period ending with the date of the disposition.

All of the income realized by a Fund is expected to be short-term or long-term capital gain income, interest income or other passive investment income of the type specifically exempt from UBTI as discussed above. None of the Funds will borrow funds for the purpose of acquiring or holding any investments or otherwise incur “acquisition indebtedness” with respect to such investments. Therefore, atax-exempt entity purchasing Shares is not expected to incur any UBTI by reason of its investment in the Shares or upon sale of such Shares provided that suchtax-exempt entity does not borrow funds for the purpose of investing in the Shares.

Under the Tax Act,tax-exempt entities are not permitted to offset losses from one trade or business against the income or gain of another trade or business. Certain net losses incurred prior to January 1, 2018 are permitted to offset gain and income created by an unrelated trade or business, if otherwise available.

Certain State and Local Taxation Matters

Prospective Shareholders should consider, in addition to the U.S. federal income tax consequences described, potential state and local tax considerations in investing in the Shares. These considerations arise under various taxing schemes, which include taxes imposed on entities treated as partnerships for U.S. federal income tax purposes, withholding on the distributive share of a nonresident partner, franchise and capital taxes, gross income taxes, net income taxes, value added taxes, and gross receipts taxes.

State and local tax laws often differ from U.S. federal income tax laws with respect to the treatment of specific items of income, gain, loss, deduction and credit for state net income tax purposes. For Shareholders that are taxed as entities for state or local tax income tax purposes, the taxable nexus, income, and apportionment factors of the Fund may flow through to the Shareholder and such flow-through may disproportionately impact the taxability of the Shareholder in one or more jurisdictions relative to that Shareholder’s distributive share from the Fund. For Shareholders that are individuals, the taxable nexus and apportioned income of the Fund will generally flow through to the Shareholder and the Shareholder’s distributive share of the taxable income or loss of the Fund generally will be required to be included in determining its reportable income for state and local income tax purposes in the jurisdiction in which the Shareholder is a resident.

The Funds may have a taxable nexus with one or more jurisdictions that will subject a Shareholder to tax (and require a Shareholder to file a state and local tax return with the jurisdiction in respect to the Shareholder’s share of the income derived from that business). A prospective Shareholder should consult its tax advisor with respect to the availability of a credit for such tax in the jurisdiction(s) in which the Shareholder is resident.

Tax Shelter Disclosure Rules

There are circumstances under which certain transactions must be disclosed to the IRS in a disclosure statement attached to a taxpayer’s U.S. federal income tax return. (A copy of such statement must also be sent to the IRS Office of Tax Shelter Analysis.) In addition, the Code imposes a requirement on certain “material advisors” to

125

maintain a list of persons participating in such transactions, which list must be furnished to the IRS upon written request. These provisions can apply to transactions not conventionally considered to involve abusive tax planning. Consequently, it is possible that such disclosure could be required by the Fund or the Shareholders (1) if a Shareholder incurs a loss (in each case, in excess of a threshold computed without regard to offsetting gains or other income or limitations) from the disposition (including by way of withdrawal) of Shares, or (2) possibly in other circumstances. Furthermore, a Fund’s material advisors could be required to maintain a list of persons investing in the Fund pursuant to the Code. While the tax shelter disclosure rules generally do not apply to a loss recognized on the disposition of an asset in which the taxpayer has a qualifying basis (generally a basis equal to the amount of cash paid by the taxpayer for such asset), such rules will apply to a taxpayer recognizing a loss with respect to interests in a pass-through entity (such as the Shares) even if its basis in such interests is equal to the amount of cash it paid. In addition, significant penalties may be imposed in connection with a failure to comply with these reporting requirements. U.S. Shareholders are urged to consult their tax advisors regarding the tax shelter disclosure rules and their possible application to them.

U.S. Shareholders should consult their own tax advisors regarding any tax reporting or filing obligations they may have as a result of their acquisition, ownership or disposition of Shares.

Backup Withholding

Each Fund is required in certain circumstances to backup withhold on certain payments paid tonon-corporate Shareholders that do not furnish the Fund with their correct taxpayer identification number (in the case of individuals, their social security number) and certain certifications, or who are otherwise subject to backup withholding. Backup withholding is not an additional tax. Any amounts withheld from payments made to a Shareholder may be refunded or credited against the Shareholder’s U.S. federal income tax liability, if any, provided that the required information is furnished to the IRS in a timely manner.

Shareholders should be aware that certain aspects of the U.S. federal, state and local income tax treatment regarding the purchase, ownership and disposition of Shares are not clear under existing law.

Thus, Shareholders are urged to consult their own tax advisors to determine the tax consequences of ownership of the Shares in their particular circumstances, including the application of U.S. federal, state, local and foreign tax laws.

FATCA

The Foreign Account Tax Compliance Act provisions of the Hiring Incentives to Restore Employment Act (“FATCA”) generally impose a reporting and 30% withholding tax regime with respect to certain items of U.S. source income (including dividends and interest) and gross proceeds from the sale or other disposal of property that can produce U.S. source interest or dividends (“Withholdable Payments”). As a general matter, the rules are designed to require U.S. persons’ direct and indirect ownership ofnon-U.S. accounts andnon-U.S. entities to be reported to the IRS. The 30% withholding tax regime applies if there is a failure to provide required information regarding U.S. ownership. The withholding rules generally apply to Withholdable Payments (other than gross proceeds of the type described above) and, beginning January 1, 2019, payments of gross proceeds of the type described above with respect to a sale or disposition.

The rules may subject anon-U.S. Shareholder’s share of Withholdable Payments received by a Fund to 30% withholding tax unless such Shareholder provides information, representations and waivers ofnon-U.S. law as may be required to comply with the provisions of the rules, including information regarding certain U.S. direct and indirect owners of suchnon-U.S. Shareholder. Anon-U.S. Shareholder that is treated as a “foreign financial institution” will generally be subject to withholding unless it agrees to report certain information to the IRS regarding its U.S. accountholders and those of its affiliates.

Although the application of the withholding rules to a sale or other disposal of an interest in a partnership is unclear, it is possible that the gross proceeds of the sale or other disposal of an interest in a Fund will be subject to tax under the withholding rules if such proceeds are treated as an indirect disposal of thenon-US. Shareholder’s interest in assets that can produce U.S. source interest or dividends, unless the sellingnon-U.S. Shareholder provides appropriate reporting information. Prospective shareholders should

126

consult their own advisors regarding the requirements under FATCA with respect to their own situation.

Euroclear System

Any participant of the Euroclear System that holds Shares in the Euroclear System will be deemed to have represented to and agreed with a Fund and Euroclear Bank as a condition to Shares being in the Euroclear System to furnish to the Euroclear Bank (a) its tax identification number, (b) notice of whether it is (i) a person who is not a United States person, (ii) a foreign government, an international organization or any wholly owned agency or instrumentality of either of the foregoing or (iii) a tax exempt identity, and (c) such other information as the Euroclear Bank may request from time to time in order to comply with its United States tax reporting obligations. If a participant in the Euroclear System fails to provide such information, Euroclear Bank may, among other courses of action, block trades in the Shares and related income distributions of such participant.

PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS BEFORE DECIDING WHETHER TO INVEST IN THE SHARES.

PURCHASES BY EMPLOYEE BENEFIT PLANS

Although there can be no assurance that an investment in a Fund, or any other managed futures product, will achieve the investment objectives of an employee benefit plan in making such investment, futures investments have certain features which may be of interest to such a plan. For example, the futures markets are one of the few investment fields in which employee benefit plans can participate in leveraged strategies without being required to pay tax on “unrelated business taxable income.” See “Material U.S. Federal Income TaxConsiderations—’Tax-Exempt Organizations’” below. In addition, because they are not taxpaying entities, employee benefit plans are not subject to paying annual tax on profits (if any) of a Fund.

General

The following section sets forth certain consequences under the Employee Retirement

Income Security Act of 1974, as amended (“ERISA”), and the Code, which a fiduciary of an “employee benefit plan” as defined in, and subject to the fiduciary responsibility provisions of, ERISA or of a “plan” as defined in and subject to Section 4975 of the Code who has investment discretion should consider before deciding to invest the plan’s assets in a Fund (such “employee benefit plans” and “plans” being referred to herein as “Plans,” and such fiduciaries with investment discretion being referred to herein as “Plan Fiduciaries”). The following summary is not intended to be complete, but only to address certain questions under ERISA and the Code which are likely to be raised by the Plan Fiduciary’s own counsel.

In general, the terms “employee benefit plan” as defined in ERISA and “plan” as defined in Section 4975 of the Code together refer to any plan or account of various types which provide retirement benefits or welfare benefits to an individual or to an employer’s employees and their beneficiaries. Such plans and accounts include, but are not limited to, corporate pension and profit-sharing plans, “simplified employee pension plans,” Keogh plans for self-employed individuals (including partners), individual retirement accounts described in Section 408 of the Code and medical benefit plans.

Each Plan Fiduciary of an ERISA Plan must give appropriate consideration to the facts and circumstances that are relevant to an investment in a Fund, including the role that such an investment in the Fund would play in the Plan’s overall investment portfolio. Each such Plan Fiduciary, before deciding to invest in a Fund, must be satisfied that such investment in the Fund is a prudent investment for the Plan, that the investments of the Plan, including the investment in a Fund, are diversified so as to minimize the risk of large losses and that an investment in a Fund complies with the documents of the Plan and related trust.

EACH PLAN FIDUCIARY CONSIDERING ACQUIRING SHARES SHOULD CONSULT WITH ITS OWN LEGAL AND TAX ADVISORS BEFORE DOING SO. AN INVESTMENT IN ANY FUND IS SPECULATIVE AND INVOLVES A HIGH DEGREE OF RISK. NO FUND IS INTENDED AS A COMPLETE INVESTMENT PROGRAM.

127

“Plan Assets”

ERISA and a regulation issued thereunder (the “Plan Asset Rules”) contain rules for determining when an investment by a Plan in an entity will result in the underlying assets of such entity being treated as assets of the Plan for purposes of the fiduciary responsibility and prohibited transaction provisions of ERISA and Section 4975 of the Code (i.e., “plan assets”). Those rules provide that assets of an entity will not be plan assets of a Plan which purchases an interest therein if certain exceptions apply, including (i) an exception applicable if the equity interest purchased is a “publicly-offered security” (the “Publicly-Offered Security Exception”), and (ii) an exception applicable if the investment by all “benefit plan investors” is not “significant” or certain other exceptions apply (the “Insignificant Participation Exception”).

The Publicly-Offered Security Exception applies if the equity interest is a security that is (1) “freely transferable,” (2) part of a class of securities that is “widely held” and (3) either (a) part of a class of securities registered under Section 12(b) or 12(g) of the Exchange Act, or (b) sold to the Plan as part of a public offering pursuant to an effective registration statement under the Securities Act and the class of which such security is a part is registered under the Exchange Act within 120 days (or such later time as may be allowed by the SEC) after the end of the fiscal year of the issuer in which the offering of such security occurred. The Plan Asset Rules state that the determination of whether a security is “freely transferable” is to be made based on all relevant facts and circumstances. Under the Plan Asset Rules, a class of securities is “widely held” only if it is of a class of securities owned by 100 or more investors independent of the issuer and of each other.

The Shares of each Fund should be considered to be publicly-offered securities. First, the Shares are being sold only as part of a public offering pursuant to an effective registration statement under the Securities Act, and the Shares were timely registered under the Exchange Act. Second, it appears that the Shares are freely transferable because the Shares of each Fund may be freely bought and sold on NYSE Arca. Third, the Shares of each Fund have been owned by at least 100 investors independent of each such Fund and of each other from the date the Shares were first sold. Therefore, the underlying assets of

each Fund should not be considered to constitute assets of any Plan which purchases Shares.

Ineligible Purchasers

In general, Shares may not be purchased with the assets of a Plan if the Managing Owner, the Commodity Broker, the Administrator, Invesco Distributors, the Index Sponsor, the Marketing Agent, the Trustee, or any of their respective affiliates or any of their respective employees either: (a) has investment discretion with respect to the investment of such plan assets; (b) has authority or responsibility to give “investment advice” as defined by the U.S. Department of Labor regulations with respect to such plan assets, for a fee; or (c) is an employer maintaining or contributing to such Plan. A party that is described in clause (a) or (b) of the preceding sentence is a fiduciary under ERISA and the Code with respect to the Plan, and any such purchase might result in a “prohibited transaction” under ERISA and the Code absent an available exemption from the prohibited transaction rules.

Form 5500 Reporting

Certain ERISA Plans may be required to report certain compensation paid by a Fund to the Fund’s service providers on Schedule C to the Plan’s annual Form 5500. To the extent applicable, any descriptions of such compensation herein are intended to satisfy the disclosure requirements for “eligible indirect compensation” for purposes of the alternative reporting option on Schedule C.

Except as otherwise set forth, the foregoing statements regarding the consequences under ERISA and the Code of an investment in a Fund are based on the provisions of the Code and ERISA as currently in effect, and the existing administrative and judicial interpretations thereunder. No assurance can be given that administrative, judicial or legislative changes will not occur that will not make the foregoing statements incorrect or incomplete.

THE PERSON WITH INVESTMENT DISCRETION SHOULD CONSULT WITH HIS OR HER ATTORNEY AND FINANCIAL ADVISERS AS TO THE PROPRIETY OF AN INVESTMENT IN A FUND IN LIGHT OF THE CIRCUMSTANCES OF THE PARTICULAR PLAN AND CURRENT TAX LAW.

128

This section does not address any laws, regulations, or statutes that may apply to prospective investors that are employee benefit plans not subject to ERISA or Section 4975 of the Code, such as U.S. federal, state and local governmental plans and certain church plans (as well as foreign plans). These other laws, regulations or statutes may impose fiduciary responsibility requirements in connection with the investment of plan assets that may be similar to ERISA. Such investors should consult their own professional advisors about these matters.

PLAN OF DISTRIBUTION

Authorized Participants

Each 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. The creation or redemption will be at the NAV of 200,000 Shares as of the closing time of the NYSE Arca or the last to close of the exchanges on which the corresponding 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 two business days after the creation order date.

Authorized Participants may offer to the public, from time to time, Shares from any Baskets they create. Shares offered to the public by Authorized Participants will be offered at a per Share offering price that will vary depending on, among other factors, the trading price of the Shares on the NYSE Arca, the NAV per Share and the supply of and demand for the Shares at the time of the offer. Shares initially comprising the same Basket but offered by Authorized Participants to the public at different times may have different offering prices. The excess, if any, of the price at which an Authorized Participant sells a Share over the price paid by such Authorized Participant in connection with the creation of such Share in a Basket will be deemed to be underwriting compensation by the FINRA Corporate Financing Department. Authorized Participants will not receive from the Fund, the Managing Owner or any of their affiliates, any fee or other compensation in

connection with their sale of Shares to the public, although investors are expected to be charged a commission by their brokers in connection with purchases of Shares that will vary from investor to investor. Investors are encouraged to review the terms of their brokerage accounts for applicable charges.

Each Fund has entered into the Distribution Services Agreement with Invesco Distributors to assist the Managing Owner with certain functions and duties relating to distribution and marketing, including reviewing and approving marketing materials. In consideration for the services provided by Invesco Distributors, the Managing Owner reimburses Invesco Distributors for actual costs associated with the performance of such services, capped at $25,000 annually. See also “Material Contracts – Distribution Services Agreement.”

As of the date of this Prospectus, each of BMO Capital Markets Corp., BNP Paribas Securities Corp, Cantor Fitzgerald & Co., Citadel Securities LLC, Citigroup Global Markets, Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc., Goldman Sachs & Co., Goldman Sachs Execution & Clearing LP, Interactive Brokers LLC, Jefferies LLC, JP Morgan Securities Inc., Knight Clearing Services LLC, Merrill Lynch Professional Clearing Corp, Morgan Stanley & Co. LLC, Nomura Securities International Inc., RBC Capital Markets LLC, SG Americas Securities LLC, Timber Hill LLC, UBS Securities, Virtu Financial BD LLC and Virtu Financial Capital Markets LLC has executed a Participant Agreement and are the only Authorized Participants.

Likelihood of Becoming a Statutory Underwriter

Each Fund issues Shares in Baskets to Authorized Participants from time to time in exchange for cash. Because new Shares can be created and issued on an ongoing basis at any point during the life of each Fund, a “distribution,” as such term is used in the Securities Act, may occur at any point. An Authorized Participant, other broker-dealer firm or its client may be deemed a statutory underwriter, and thus may be subject to the prospectus-delivery and liability provisions of the Securities Act, if it purchases a Basket from any Fund, breaks the Basket down into the constituent

129

Shares and sells the Shares to its customers; or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for the Shares. A determination of whether one is an underwriter must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that would lead to categorization as an underwriter. Authorized Participants, other broker-dealers and other persons are cautioned that some of their activities may result in their being deemed participants in a distribution, under certain interpretations of applicable law, in a manner which would render them statutory underwriters and subject them to the prospectus-delivery and liability provisions of the Securities Act.

Dealers who are neither Authorized Participants nor “underwriters” but are participating in a distribution (as contrasted to ordinary secondary trading transactions), and thus dealing with Shares that are part of an “unsold allotment” within the meaning of section 4(a)(3)(C) of the Securities Act, would be unable to take advantage of the prospectus delivery exemption provided by section 4(a)(3) of the Securities Act.

General

Retail investors may purchase and sell Shares through traditional brokerage accounts. Investors who purchase Shares through acommission/fee-based brokerage account may pay commissions/fees charged by the brokerage account. Investors are encouraged to review the terms of their brokerage accounts for applicable charges.

Investors intending to create or redeem Baskets through Authorized Participants in transactions not involving a broker-dealer registered in such investor’s state of domicile or residence should consult their legal advisor regarding applicable broker-dealer or securities regulatory requirements under the state securities laws prior to such creation or redemption.

The Managing Owner has agreed to indemnify certain parties against certain liabilities, including

liabilities under the Securities Act, and to contribute to payments that such parties may be required to make in respect of those liabilities. The Trustee has agreed to reimburse such parties, solely from and to the extent of each respective Fund’s assets, for indemnification and contribution amounts due from the Managing Owner in respect of such liabilities to the extent the Managing Owner has not paid such amounts when due.

The offering of Baskets is being made in compliance with FINRA Rule 2310. Accordingly, the Authorized Participants will not make any sales to any account over which they have discretionary authority without the prior written approval of a purchaser of Shares. The maximum amount of items of value to be paid to FINRA Members in connection with the offering of the Shares by a Fund will not exceed 10% of the gross offering proceeds of such Shares.

131

The Authorized Participants will not charge a commission of greater than 0.99% of the gross offering proceeds of such Shares of the Trust.

Pursuant to the Distribution Services Agreement, Invesco Distributors will be paid by the Managing Owner out of the Management Fee of each Fund in an amount capped up to $25,000 per annum with respect to each Fund.

The Marketing Agent will be paid a marketing services fee by the Managing Owner. For each year ending on or prior to the sixth anniversary of the date of the Services Agreement, the marketing services fee will equal to the sum of: (i) 0.00345 times the lesser of Total Average Net Assets and $6,000,000,000, plus (ii) If such Total Average Net Assets were greater than $6,000,000,000, 0.002625 times the lesser of (A) the excess of such Total Average Net Assets over $6,000,000,000 and (B) $3,000,000,000, plus (iii) If such Total Average Net Assets were greater than $9,000,000,000, 0.000975 times the lesser of (A) the excess of such Total Average Net Assets over $9,000,000,000 and (B) $3,000,000,000, plus (iv) If such Total Average Net Assets were greater than $12,000,000,000, 0.00015 times the excess of such Total Average Net Assets over $12,000,000,000. For each year ending on or after to the sixth anniversary of the date of the Services Agreement, the marketing services fee will equal to 0.0005 times Total Average Net Assets. “Total Average Net Assets” means the sum of the “Average Net Assets” of all “Funds” for such period. “Average Net Assets” means in respect of any Fund, the average of the total NAV of such Fund (determined as described in its prospectus) as of the close of trading on each day of the applicable determination year during which the market on which such Fund is or was listed for trading was open for trading. If a Fund was opened or terminated, or the applicable marketing services from the Marketing Agent were initiated or terminated, in the course of a determination year, the Average Net Assets will continue to be calculated with respect to all trading days in such determination year but with a value of zero for days on which the Fund did not exist or the Marketing Agent’s marketing services had been terminated or not yet initiated. For purposes of this paragraph only, “Funds” means, collectively, PowerShares DB Agriculture Fund, PowerShares DB Base Metals Fund, PowerShares DB Commodity Index Tracking Fund, PowerShares DB Energy Fund,

PowerShares DB G10 Currency Harvest Fund, PowerShares DB Gold Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund, PowerShares DB Silver Fund, PowerShares DB US Dollar Index Bearish Fund, PowerShares DB US Dollar Index Bullish Fund, and “New Invesco ETFs”. New Invesco ETF means, in part, any fund that both (i) is formed and sponsored or advised on or after the date of the Services Agreement by the Managing Owner or an affiliate and (ii) meets all of the following criteria: (1) is a vehicle that both (a) is listed, traded or sold in North America, Central America or South America and (b) either (i) has an investment strategy substantially similar to that of a Fund or (ii) satisfies (or would, if sponsored by the Managing Owner, satisfy) all of the criteria set forth in clauses (ii)(1) and (b) herein; (2) is marketed as having a principal investment objective of providing exposure to certain designated commodities or derivatives thereof, whether long, short, or otherwise; and (3) (A) invests, is permitted to invest in, or which has as a principal investment strategy the investment of, more than 51% of its net assets in certain designated commodities, or (B) establishes or maintains, is permitted to establish or maintain, or which has as a principal investment strategy to establish or maintain, exposure to derivatives of certain designated commodities with a gross aggregate notional value greater than 51% of its NAV.

The payments to Invesco Distributors and the Marketing Agent will not, in the aggregate (of the Trust, and not on a Fund by Fund basis), exceed 0.25% and 8.75%, respectively, of the gross offering proceeds of the offering. Invesco Distributors and the Marketing Agent will monitor compensation received in connection with the Fund to determine if the payments described hereunder must be limited, when combined with selling commissions charged and any price spreads realized by other FINRA members, in order to comply with the 10% limitation on total underwriters’ compensation pursuant to FINRA Rule 2310.

The Marketing Agent’s compensation is also subject to the limitations under NASD Rule 2830, which governs the underwriting compensation which may be paid in respect of investment companies.

THE FUTURES MARKETS

Futures Contracts

Futures contracts are standardized contracts made on United States or foreign exchanges that call for the future delivery of specified quantities of various agricultural and tropical commodities, industrial commodities, currencies, financial instruments or metals at a specified time and place. The contractual obligations, depending upon whether one is a buyer or a seller, may be satisfied either by taking or making, as the case may be, physical delivery of an approved grade of commodity or by making an offsetting sale or purchase of an equivalent but opposite futures contract on the same, or mutuallyoff-setting, exchange prior to the designated date of delivery. As an example of an offsetting transaction where the physical commodity is not delivered, the contractual obligation arising from the sale of one contract of December wheat on a futures exchange may be fulfilled at any time before delivery of the commodity is required by the purchase of one contract of December wheat on the

same exchange. The difference between the price at which the futures contract is sold or purchased and the price paid for the offsetting purchase or sale, after allowance for brokerage commissions, constitutes the profit or loss to the trader. Certain futures contracts, such as those for stock, financial or economic indices approved by the CFTC, or Eurodollar contracts, settle in cash (irrespective of whether any attempt is made to offset such contracts) rather than delivery of any physical commodity.

Hedgers and Speculators

The two broad classes of persons who trade futures contracts are “hedgers” and “speculators.” Commercial interests, including farmers, that market or process commodities, and financial institutions that market or deal in commodities, including interest rate sensitive instruments, foreign currencies and stocks, and which are exposed to currency, interest rate and stock market risks, may use the futures markets for hedging. Hedging is a protective procedure designed to minimize losses that may occur because of price fluctuations occurring, for example, between the time a processor makes a contract to buy or sell a raw or processed commodity at a certain price and the time he must perform the contract. The futures markets enable the hedger to shift the risk of price fluctuations to the speculator. The speculator risks his capital with the hope of making profits from price fluctuations in futures contracts. Speculators rarely take delivery of commodities, but rather close out their positions by entering into offsetting purchases or sales of futures contracts. Since the speculator may take either a long or short position in the futures markets, it is possible for him to make profits or incur losses regardless of whether prices go up or down.

Futures Exchanges

Futures exchanges provide centralized market facilities for trading futures contracts and options thereon (but not forward contracts). Members of, and trades executed on, a particular exchange are subject to the rules of that exchange. Among the principal exchanges in the United States are the Chicago Board of Trade, the Chicago Mercantile Exchange, the New York Mercantile Exchange, and ICE Futures U.S.

Each futures exchange in the United States has an associated “clearing house.” Once trades between

137

members of an exchange have been confirmed, the clearing house becomes substituted for each buyer and each seller of contracts traded on the exchange and, in effect, becomes the other party to each trader’s open position in the market. Thereafter, each party to a trade looks only to the clearing house for performance. The clearing house generally establishes a guarantee fund to which all clearing members of the exchange must contribute; this fund acts as an emergency buffer that enables the clearing house, at least to a large degree, to meet its obligations with regard to the “other side” of an insolvent clearing member’s contracts. Furthermore, clearing houses require margin deposits and continuously mark positions to market to provide some assurance that their members will be able to fulfill their contractual obligations. Thus, a central function of the clearing houses is to ensure the integrity of trades. Members effecting futures transactions on an organized exchange typically need not worry about the solvency of the party on the opposite side of the trade but, rather their concerns are the respective solvencies of their commodity broker and the clearing house. The clearing house “guarantee” of performance on open positions does not run to customers. If a member firm goes bankrupt, customers could lose money.

Foreign futures exchanges differ in certain respects from their U.S. counterparts. In contrast to U.S. exchanges, certain foreign exchanges are “principals’ markets,” where trades remain the liability of the traders involved, and the exchange clearing house does not become substituted for any party. See “Risk Factors – Trading on Futures Exchanges Outside the United States is Not Subject to U.S. Regulation.”

Regulations

Futures exchanges in the United States are subject to regulation under the Commodity Exchange Act by the CFTC, the governmental agency having responsibility for regulation of futures exchanges and trading on those exchanges.

The Commodity Exchange Act and the CFTC also regulate the activities of “commodity trading advisors” and “commodity pool operators” and the CFTC has adopted regulations with respect to certain of such persons’ activities. Pursuant to its authority, the CFTC requires a commodity pool operator (such

as the Managing Owner) to keep accurate, current and orderly records with respect to each pool it operates. The CFTC may suspend the registration of a commodity pool operator if the CFTC finds that the operator has violated the Commodity Exchange Act or regulations thereunder and in certain other circumstances. Suspension, restriction or termination of the Managing Owner’s registration as a commodity pool operator would prevent it, until such time (if any) as such registration were to be reinstated, from managing, and might result in the termination of, the Trust. The Commodity Exchange Act gives the CFTC similar authority with respect to the activities of commodity trading advisors, such as the Managing Owner. If the registration of the Managing Owner as a commodity trading advisor were to be terminated, restricted or suspended, the Managing Owner would be unable, until such time (if any) as such registration were to be reinstated, to render trading advice to the Fund. The Funds are not registered with the CFTC in any capacity.

The Commodity Exchange Act requires all “futures commission merchants,” such as the Commodity Broker, to meet and maintain specified fitness and financial requirements, segregate customer funds from proprietary funds and account separately for all customers’ funds and positions, and to maintain specified book and records open to inspection by the staff of the CFTC.

The Commodity Exchange Act also gives the states certain powers to enforce its provisions and the regulations of the CFTC.

Shareholders are afforded certain rights for reparations under the Commodity Exchange Act. Shareholders may also be able to maintain a private right of action for certain violations of the Commodity Exchange Act. The CFTC has adopted rules implementing the reparation provisions of the Commodity Exchange Act which provide that any person may file a complaint for a reparations award with the CFTC for violation of the Commodity Exchange Act against a floor broker, futures commission merchant, introducing broker, commodity trading advisor, commodity pool operator, and their respective associated persons.

Pursuant to authority in the Commodity Exchange Act, the NFA has been formed and registered with the CFTC as a “registered futures

138

association.” At the present time, the NFA is the onlynon-exchange self-regulatory organization for derivatives professionals. NFA members are subject to NFA standards relating to fair trade practices, market integrity, and consumer protection. As the self-regulatory body of the derivatives industry, the NFA promulgates rules governing the conduct of derivatives professionals and disciplines those professionals who do not comply with such standards. The CFTC has delegated to the NFA responsibility for the registration of commodity trading advisors, commodity pool operators, futures commission merchants, introducing brokers, and swap dealers, among others, and their respective associated persons, as applicable, and floor brokers. The Commodity Broker and the Managing Owner are members of the NFA (the Funds are not required to become members of the NFA).

The CFTC has no authority to regulate trading on foreign futures exchanges and markets but permits direct access to such markets from the United States with respect to foreign boards of trade that are registered as such with the CFTC.

Margin

“Initial” or “original” margin is the minimum amount of funds that must be deposited by a futures trader with his commodity broker in order to initiate futures trading or to maintain an open position in futures contracts. “Maintenance” margin is the amount (generally less than initial margin) to which a trader’s account may decline before he must deliver additional margin. A margin deposit is like a cash performance bond. It helps assure the futures trader’s performance of the futures contract that the trader purchases or sells. Futures contracts are customarily bought and sold on margin that represents a very small percentage (ranging upward from less than 2%) of the purchase price of the underlying commodity being traded. Because of such low margins, price fluctuations occurring in the futures markets may create profits and losses that are greater, in relation to the amount invested, than are customary in other forms of investments. The minimum amount of margin required in connection with a particular futures contract is set from time to time by the exchange on which such contract is traded, and may be modified from time to time by the exchange during the term of the contract.

Brokerage firms carrying accounts for traders in futures contracts may not accept lower, and generally require higher, amounts of margin as a matter of policy in order to afford further protection for themselves.

Margin requirements are computed each day by a commodity broker. When the market value of a particular open futures contract position changes to a point where the margin on deposit does not satisfy maintenance margin requirements, a margin call is made by the commodity broker. If the margin call is not met within a reasonable time, the broker may close out a Fund’s position. With respect to the Managing Owner’s trading, only the Managing Owner, and not a Fund or its Shareholders personally, will be subject to margin calls.
