PowerShares DB Silver Fund

Notes to Unaudited Financial Statements

September 30, 2011

(1) Organization

PowerShares DB Silver Fund (the “Fund”), a separate series of PowerShares DB Multi-Sector Commodity Trust (the “Trust”), a Delaware statutory trust organized in seven separate series, was formed on August 3, 2006. DB Commodity Services LLC, a Delaware limited liability company (“DBCS” or the “Managing Owner”), seeded the Fund with a capital contribution of $1,000 in exchange for 40 General Shares of the Fund. The fiscal year end of the Fund is December 31^st. The term of the Fund is perpetual (unless terminated earlier in certain circumstances) as provided for in the Second Amended and Restated Declaration of Trust and Trust Agreement of the Trust (the “Trust Agreement”).

The Fund was originally formed as a master-feeder structure. Prior to the close of business on December 31, 2010, the master-feeder structure was collapsed. As a result of the collapse of the master-feeder structure, on December 31, 2010, the Managing Owner’s and the Fund’s interests in the DB Silver Master Fund (the “Master Fund”) were redeemed for all assets and liabilities held by the Master Fund. Hereafter, all references to the Fund either represent the structure in place as of December 31, 2010 or the structure in place prior to such date whereby the financial statements reflect the consolidation of the Fund and the Master Fund. The collapse of the master-feeder structure had no impact on a Shareholder’s net asset value or the results of operations for the Fund.

The Fund offers common units of beneficial interest (the “Shares”) only to certain eligible financial institutions (the “Authorized Participants”) in one or more blocks of 200,000 Shares, called a Basket. The Fund commenced investment operations on January 3, 2007. The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC (the “NYSE Alternext”)) on January 5, 2007 and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

This Report covers the three months ended September 30, 2011 and 2010 (hereinafter referred to as the “Three Months Ended September 30, 2011” and the “Three Months Ended September 30, 2010”, respectively) and the nine months ended September 30, 2011 and 2010 (hereinafter referred to as the “Nine Months Ended September 30, 2011” and the “Nine Months Ended September 30, 2010”, respectively).

(2) Fund Investment Overview

The Fund invests with a view to tracking the changes, whether positive or negative, in the level of the DBIQ Optimum Yield Silver Index Excess Return™ (the “DBIQ-OY SI ER™”, or the “Index”) over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund.

The Index is intended to reflect the change in market value of the silver sector. The single commodity comprising the Index is silver (the “Index Commodity”). From January 3, 2007 to December 31, 2010, the Fund invested with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank Liquid Commodity Index-Optimum Yield Silver Excess Return™ (the “Interim Index”) over time, plus the excess, if any, of the Fund’s income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. After December 31, 2010, the Fund commenced tracking the Index. The Fund’s Interim Index is identical to the Index except with respect to the following non-substantive changes: (i) name of Index, and (ii) inception date of Index for Commodity Futures Trading Commission (the “CFTC”) purposes. Except as provided in the immediately preceding sentence, all prior underlying formulae, data (e.g., closing levels, measure of volatility, all other numerical statistics and measures) and all other characteristics (e.g., Base Date, Index Sponsor, rolling, etc.) with respect to the Interim Index is identical to the Index. The Fund also holds United States Treasury Obligations and other high credit quality short-term fixed income securities for deposit with the Fund’s commodity broker as margin.

The CFTC and/or commodity exchanges, as applicable, impose position limits on market participants trading in the commodity included in the Index. The Index is comprised of futures contracts on the Index Commodity that expire in a specific month and trade on a specific exchange (the “Index Contracts”). As disclosed in the Fund’s Prospectus, if the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to the Index Commodity by investing in the Index Contract, the Fund may invest in a futures contract referencing the Index Commodity other than the Index Contract or, in the alternative, invest in other futures contracts not based on the Index Commodity if, in the commercially reasonable judgment of the Managing Owner, such futures contracts tend to exhibit trading prices that correlate with the Index Commodity. Please seehttp://dbfunds.db.com/dbs/weights.aspx with respect to the most recently available weighted composition of the Fund andhttp://dbfunds.db.com/dbs/index.aspx with respect to the composition of the Index on the Base Date.

The Fund does not employ leverage. As of September 30, 2011 and December 31, 2010, the Fund had $157,362,630 (or 100%) and $207,694,990 (or 100%), respectively, of its holdings of cash, United States Treasury Obligations and unrealized appreciation/depreciation on futures contracts on deposit with its Commodity Broker. Of this, $26,473,500 (or 16.82%) and

For additional information, please see the unaudited Schedule of Investments as of September 30, 2011 and the audited Schedule of Investments as of December 31, 2010 for details of the Fund’s portfolio holdings.

(4) Summary of Significant Accounting Policies

(a) Basis of Presentation

The financial statements of the Fund have been prepared using U.S. generally accepted accounting principles and include the financial statements of the Fund and the Master Fund when applicable. As described in note 1, the Fund was originally formed as a master-feeder structure and such structure was collapsed on December 31, 2010. The financial statements reflect consolidation of the Fund and the Master Fund for all periods presented prior to December 31, 2010. Upon the initial offering of the Shares on January 3, 2007, the capital raised by the Fund was used to purchase 100% of the common units of beneficial interest of the Master Fund (the “Master Fund Limited Units”) (excluding common units of beneficial interest of the Master Fund held by the Managing Owner (the “Master Fund General Units”)). The Master Fund Limited Units owned by the Fund provided the Fund and its investors certain controlling rights and abilities over the Master Fund. Consequently, the financial statement balances of the Master Fund were consolidated with the Fund’s financial statement balances for the periods previously described, and all significant inter-company balances and transactions were eliminated.

(b) Use of Estimates

The preparation of the financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosure of contingent assets and liabilities during the reporting period of the financial statements and accompanying notes. Actual results could differ from those estimates.

(c) Financial Instruments and Fair Value

United States Treasury Obligations and commodity futures contracts are recorded in the statements of financial condition on a trade date basis at fair value with changes in fair value recognized in earnings in each period. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).

Financial Accounting Standards Board (FASB) fair value measurement and disclosure guidance requires a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Basis of Fair Value Measurement

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly;

Level 3: Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

12

PowerShares DB Silver Fund

Notes to Unaudited Financial Statements—(Continued)

September 30, 2011

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

In determining fair value of United States Treasury Obligations and commodity futures contracts, the Fund uses unadjusted quoted market prices in active markets. United States Treasury Obligations and commodity futures contracts are classified within Level 1 of the fair value hierarchy. The Fund does not adjust the quoted prices for United States Treasury Obligations and commodity futures contracts.

(d) Deposits with Broker

The Fund deposits cash and United States Treasury Obligations with its Commodity Broker subject to CFTC regulations and various exchange and broker requirements. The combination of the Fund’s deposits with its Commodity Broker of cash and United States Treasury Obligations and the unrealized profit or loss on open futures contracts (variation margin) represents the Fund’s overall equity in its broker trading account. To meet the Fund’s initial margin requirements, the Fund holds United States Treasury Obligations. The Fund uses its cash held by the Commodity Broker to satisfy variation margin requirements. The Fund earns interest on its cash deposited with the Commodity Broker.

(e) United States Treasury Obligations

The Fund records purchases and sales of United States Treasury Obligations on a trade date basis. These holdings are marked to market based on quoted market closing prices. The Fund holds United States Treasury Obligations for deposit with the Fund’s Commodity Broker to meet margin requirements and for trading purposes. Interest income is recognized on an accrual basis when earned. Premiums and discounts are amortized or accreted over the life of the United States Treasury Obligations. Included in the United States Treasury Obligations as of September 30, 2011 and December 31, 2010 were holdings of $26,473,500 and $14,051,138, respectively, which were restricted and held against initial margin of the open futures contracts.

(f) Cash Held by Broker

The Fund’s arrangement with the Commodity Broker requires the Fund to meet its variation margin requirement related to the price movements, both positive and negative, on futures contracts held by the Fund by keeping cash on deposit with the Commodity Broker. The Fund defines cash and cash equivalents to be highly liquid investments, with original maturities of three months or less when purchased. As of September 30, 2011, the Fund had $118,305,308 of cash held with the Commodity Broker, of which $42,440,865 was on deposit to satisfy the Fund’s negative variation margin on open futures contracts. As of December 31, 2010 the Fund had $16,315,594 of cash held with the Commodity Broker. There were no cash equivalents held by the Fund as of September 30, 2011 and December 31, 2010.

(g) Income Taxes

The Fund is classified as a partnership for U.S. federal income tax purposes. Accordingly, the Fund will not incur U.S. federal income taxes. No provision for federal, state, and local income taxes has been made in the accompanying financial statements, as investors are individually liable for income taxes, if any, on their allocable share of the Fund’s income, gain, loss, deductions and other items.

The major tax jurisdiction for the Fund and the earliest tax year subject to examination: United States 2007.

(h) Futures Contracts

All commodity futures contracts are held and used for trading purposes. The commodity futures are recorded on a trade date basis and open contracts are recorded in the statement of financial condition at fair value on the last business day of the period, which represents market value for those commodity futures for which market quotes are readily available. However, when market closing prices are not available, the Managing Owner may value an asset of the Fund pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. Realized gains (losses) and changes in unrealized appreciation (depreciation) on open positions are determined on a specific identification basis and recognized in the statement of income and expenses in the period in which the contract is closed or the changes occur, respectively. As of September 30, 2011 and December 31, 2010, the futures contracts held by the Fund were in a net unrealized depreciation position of $42,440,865 and in a net unrealized appreciation position of $31,905,340, respectively.

(i) Management Fee

The Fund pays the Managing Owner a management fee (the “Management Fee”), monthly in arrears, in an amount equal to 0.75% per annum of the daily net asset value of the Fund. The Management Fee is paid in consideration of the Managing Owner’s commodity futures trading advisory services.

September 30, 2011

(j) Brokerage Commissions and Fees

The Fund incurs 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 by the Commodity Broker. These costs are recorded as brokerage commissions and fees in the statement of income and expenses as incurred. The Commodity Broker’s brokerage commissions and trading fees are determined on a contract-by-contract basis. On average, total charges paid to the Commodity Broker were less than $10.00 per round-turn trade for the Three Months Ended September 30, 2011 and 2010 and the Nine Months Ended September 30, 2011 and 2010.

(k) Routine Operational, Administrative and Other Ordinary Expenses

The Managing Owner assumes all routine operational, administrative and other ordinary expenses of the Fund, including, but not limited to, computer services, the fees and expenses of the Trustee, legal and accounting fees and expenses, tax preparation expenses, filing fees and printing, mailing and duplication costs. Accordingly, all such expenses are not reflected in the statement of income and expenses of the Fund.

(l) Organizational and Offering Costs

All organizational and offering expenses of the Fund are incurred and assumed by the Managing Owner. The Fund is not responsible to the Managing Owner for the reimbursement of organizational and offering costs. Expenses incurred in connection with the continuous offering of Shares also will be paid by the Managing Owner.

(m) Non-Recurring and Unusual Fees and Expenses

The Fund pays all fees and expenses which are non-recurring and unusual in nature. Such expenses include legal claims and liabilities, litigation costs or indemnification or other unanticipated expenses. Such fees and expenses, by their nature, are unpredictable in terms of timing and amount. For the Three Months Ended September 30, 2011 and 2010 and the Nine Months Ended September 30, 2011 and 2010, the Fund did not incur such expenses.

(5) Fair Value Measurements

The Fund’s assets and liabilities recorded at fair value have been categorized based upon the fair value hierarchy discussed in Note 4(c).

Assets and Liabilities Measured at Fair Value were as follows:

	September 30, 2011			December 31, 2010
United States Treasury Obligations (Level 1)	$	81,498,187		$	159,474,056
Commodity Futures Contracts (Level 1)	$	(42,440,865	)	$	31,905,340

There were no Level 2 or Level 3 holdings as of September 30, 2011 and December 31, 2010.

(6) Financial Instrument Risk

In the normal course of its business, the Fund is a party to financial instruments with off-balance sheet risk. The term “off-balance sheet risk” refers to an unrecorded potential liability that, even though it does not appear on the balance sheet, may result in a future obligation or loss. The financial instruments used by the Fund are commodity futures, whose values are based upon an underlying asset and generally represent future commitments that have a reasonable possibility of being settled in cash or through physical delivery. The financial instruments are traded on an exchange and are standardized contracts.

Market risk is the potential for changes in the value of the financial instruments traded by the Fund due to market changes, including fluctuations in commodity prices. In entering into these futures contracts, there exists a market risk that such futures contracts may be significantly influenced by adverse market conditions, resulting in such futures contracts being less valuable. If the markets should move against all of the futures contracts at the same time, the Fund could experience substantial losses.

Credit risk is the possibility that a loss may occur due to the failure of an exchange clearinghouse to perform according to the terms of a futures contract. Credit risk with respect to exchange-traded instruments is reduced to the extent that an exchange or clearing organization acts as a counterparty to the transactions. The Fund’s risk of loss in the event of counterparty default is typically limited to the amounts recognized in the statement of financial condition and not represented by the futures contract or notional amounts of the instruments.

PowerShares DB Silver Fund

Notes to Unaudited Financial Statements—(Continued)

September 30, 2011

The Fund has not utilized, nor does it expect to utilize in the future, special purpose entities to facilitate off-balance sheet financing arrangements and has no loan guarantee arrangements or off-balance sheet arrangements of any kind, other than agreements entered into in the normal course of business noted above.

(7) Share Purchases and Redemptions

(a) Purchases

Shares may be purchased from the Fund only by Authorized Participants in one or more blocks of 200,000 Shares, called a Basket. The Fund issues Shares in Baskets only to Authorized Participants continuously as of noon, New York time, on the business day immediately following the date on which a valid order to create a Basket is accepted by the Fund, at the net asset value of 200,000 Shares as of the closing time of the NYSE Arca or the last to close of the exchanges on which the Fund’s assets are traded, whichever is later, on the date that a valid order to create a Basket is accepted by the Fund.

(b) Redemptions

On any business day, an Authorized Participant may place an order with the Managing Owner to redeem one or more Baskets. Redemption orders must be placed by 10:00 a.m., New York time. The day on which the Managing Owner receives a valid redemption order is the redemption order date. Redemption orders are irrevocable. The redemption procedures allow Authorized Participants to redeem Baskets. Individual shareholders may not redeem directly from the Fund.

By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through The Depository Trust Company’s (the “DTC”) book-entry system to the Fund not later than noon, New York time, on the business day immediately following 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 the non-refundable transaction fee due for the redemption order.

The redemption proceeds from the Fund consist of the cash redemption amount. The cash redemption amount is equal to the net asset value of the number of Basket(s) 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 the Fund’s assets are traded, whichever is later, on the redemption order date. The Fund will distribute the cash redemption amount at noon, New York time, on the business day immediately following the redemption order date through DTC to the account of the Authorized Participant as recorded on DTC’s book-entry system.

The redemption proceeds due from the Fund are delivered to the Authorized Participant at noon, New York time, on the business day immediately following the redemption order date if, by such time on such business day immediately following the redemption order date, 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 proceeds are delivered to the extent of whole Baskets received. Any remainder of the redemption proceeds are delivered on the next business day to the extent of remaining whole Baskets received if the Managing Owner 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 noon, New York time, on such next business day. Any further outstanding amount of the redemption order will be canceled. The Managing Owner is also authorized to deliver the redemption proceeds notwithstanding that the Baskets to be redeemed are not credited to the Fund’s DTC account by noon, New York time, on the business day immediately following the redemption order 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 from time-to-time agree upon.

preceding month. Any losses allocated to the Managing Owner (as the owner of the General Shares) which are in excess of the Managing Owner’s capital balance are allocated to the Shareholders in accordance with their respective interest in the Fund as a percentage of total shareholders’ equity. Distributions (other than redemption of units) may be made at the sole discretion of the Managing Owner on apro rata basis in accordance with the respective capital balances of the shareholders.

(9) Commitments and Contingencies

The Managing Owner, either in its own capacity or in its capacity as the Managing Owner and on behalf of the Fund, has entered into various service agreements that contain a variety of representations, or provide indemnification provisions related to certain risks service providers undertake in performing services which are in the best interests of the Fund. As of September 30, 2011, no claims had been received by the Fund and it was therefore not possible to estimate the Fund’s potential future exposure under such indemnification provisions.

(10) Net Asset Value and Financial Highlights

The Fund is presenting the following net asset value and financial highlights related to investment performance for a Share outstanding for the Three Months Ended September 30, 2011 and 2010 and for the Nine Months Ended September 30, 2011 and 2010. The net investment income and total expense ratios are calculated using average net asset value. The net asset value presentation is calculated using daily Shares outstanding. The net investment income and total expense ratios have been annualized. The total return is based on the change in net asset value of the Shares during the period. An individual investor’s return and ratios may vary based on the timing of capital transactions. Net asset value per Share is the net asset value of the Fund divided by the number of outstanding Shares.

Overview/Introduction

Prior to the close of business on December 31, 2010, the Fund invested substantially all of its assets in the DB Silver Master Fund (the “Master Fund”), a series of the DB Multi-Sector Commodity Trust (the “Master Trust”). After the determination of the net asset value of the Master Fund on December 31, 2010, the Master Fund transferred and distributed all of its assets and liabilities to the Fund and terminated. Effective January 1, 2011, the reorganized Fund has performed all of the necessary functions in order to continue normal Fund operations. The collapse of the master-feeder structure had no effect on the operations or processes of the Fund. All reference to historical results of the Fund include results of the Master Fund where the context requires.

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

From January 3, 2007 to December 31, 2010, the Fund invested with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank Liquid Commodity Index-Optimum Yield Silver Excess Return™ (the “Interim Index”) over time, plus the excess, if any, of the Fund’s income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. After December 31, 2010, the Fund commenced tracking the Index. The Fund’s Interim Index is identical to the Index except with respect to the following non-substantive changes: (i) name of Index, and (ii) inception date of Index for Commodity Futures Trading Commission (the “CFTC”) purposes. Except as provided in the immediately preceding sentence, all prior underlying formulae, data (e.g., closing levels, measure of volatility, all other numerical statistics and measures) and all other characteristics (e.g., Base Date, Index Sponsor, rolling, etc.) with respect to the Interim Index are identical to the Index.

The Fund pursues its investment objective by investing in a portfolio of exchange-traded futures contracts that expire in a specific month and trade on a specific exchange (the “Index Contracts”) in the single commodity comprising the Index (the “Index Commodity”). The single Index Commodity is silver. The Index is composed of notional amounts of the Index Commodity. The Fund also holds United States Treasury Obligations and other high credit quality short-term fixed income securities for deposit with the Fund’s Commodity Broker as margin.

DBLCI™, DBIQ™ and Deutsche Bank Liquid Commodity Index™ are trademarks of Deutsche Bank AG London (the “Index Sponsor”). Trademark applications in the United States are pending with respect to both the Trust and aspects of the Index. The Trust, the Fund and the Managing Owner have been licensed by the Index Sponsor to use the above noted trademarks. Deutsche Bank AG London is an affiliate of the Trust, the Fund and the Managing Owner.

The Index is composed of one underlying Index Commodity. The closing level of the Index is calculated on each business day by the Index Sponsor based on the closing price of the futures contracts for the underlying Index Commodity and the notional amount of such Index Commodity.

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

The Index includes provisions for the replacement of futures contracts as they approach maturity. This replacement takes place over a period of time in order to lessen the impact on the market for the futures contracts being replaced. With respect to the Index

17

Commodity, the 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), the Index Commodity rolls to the futures contract which generates the best possible “implied roll yield.” The futures contract with a delivery month within the next thirteen months which generates the best possible implied roll yield will be included in the Index. As a result, the Index Commodity is able to potentially maximize the roll benefits in backwardated markets and minimize the losses from rolling in contangoed markets.

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

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

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

On the first New York business day (the “Verification Date”) of each month, the Index Commodity futures contract will be tested in order to determine whether to continue including it in the 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 the Index. For example, if the first New York business day is October 1, 2011, and the Delivery Month of the Index Commodity futures contract currently in such Index is November 2011, a new Index Commodity futures contract with a later Delivery Month will be selected.

For the underlying Index Commodity of the 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 the Index, and (ii) no later than the 13^th month after the Verification Date. For example, if the first New York business day is October 1, 2011 and the Delivery Month of an Index Commodity futures contract currently in the Index is November 2011, the Delivery Month of an eligible new Index Commodity futures contract must be between December 2011 and October 2012. 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, the monthly roll for the Index Commodity subject to a roll in that particular month unwinds the old futures contract and enters a position in the new futures contract. This takes place between the 2^nd and 6^thIndex Business Day of the month.

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

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

The CFTC and/or commodity exchanges, as applicable, impose position limits on market participants trading in the commodity included in the Index. As disclosed in the Fund’s Prospectus, if the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to the Index Commodity by investing in a specific Index Contract, the Fund may invest in a futures contract referencing the Index Commodity other than the Index Contract or, in the alternative, invest in other futures contracts not based on the Index Commodity if, in the commercially reasonable judgment of the Managing Owner, such futures contracts tend to exhibit trading prices that correlate with the Index Commodity. Please seehttp://dbfunds.db.com/dbs/weights.aspx with respect to the most recently available weighted composition of the Fund andhttp://dbfunds.db.com/dbs/index.aspx with respect to the composition of the Index on the Base Date.

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

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

The Shares are intended to provide investment results that generally correspond to the changes, positive or negative, in the levels of the Index over time. The value of the Shares is expected to fluctuate in relation to changes in the value of the Fund’s portfolio. The market price of the Shares may not be identical to the net asset value per Share, but these two valuations are expected to be very close.

Margin Calls

Like other futures and derivatives traders, the Fund will be subject to margin calls from time-to-time. The term “margin” has a different meaning in the context of futures contracts and other derivatives than it does in the context of securities. In particular, “margin” on a futures position does not constitute a borrowing of money or the collateralization of a loan. The Fund does not borrow money.

To establish a position in an exchange-traded futures contract, the Fund makes a deposit of “initial margin.” The amount of initial margin required to be deposited in order to establish a position in an exchange-traded futures contract varies from instrument to instrument depending, generally, on the historical volatility of the futures contract in question. Determination of the amount of the required initial margin deposit in respect of a particular contract is made by the exchange on which the contract is listed. To establish a long position in an over-the-counter instrument, the counterparty may require an analogous deposit of collateral, depending upon the anticipated volatility of the instrument and the creditworthiness of the person seeking to establish the position. The deposit of initial margin provides assurance to futures commission merchants and clearing brokers involved in the settlement process that sufficient resources are likely to be on deposit to enable a client’s position to be closed by recourse to the initial margin deposit should the client fail to meet a demand for variation margin, even if changes in the value of the contract in question, which are marked to market from day to day, continue to reflect the contract’s historical volatility. Collateral deposited in support of an over-the-counter instrument serves a similar purpose.

Once a position has been established on a futures exchange, “variation margin” generally is credited or assessed at least daily to reflect changes in the value of the position. In contrast to “initial margin,” “variation margin” represents a system of marking to market the futures contract’s value. Thus, traders in exchange-traded futures contracts are assessed daily in an amount equal to that day’s accumulated losses in respect of any open position (or are credited daily with accumulated gains in respect of such position). Collateral may move between the parties to an over-the-counter instrument in a similar manner as gains or losses accumulate in the instrument. As with initial margin, variation margin serves to secure the obligations of the investor under the contract and to protect those involved in the settlement process against the possibility that a client will have insufficient resources to meet its contractual obligations. Collateral deposited in support of an over-the-counter instrument serves a similar purpose. Like initial margin (or an equivalent deposit of collateral), variation margin (or an equivalent deposit of collateral) does not constitute a borrowing of money, is not considered to be part of the contract purchase price and is returned upon the contract’s termination unless it is used to cover a loss in the contract position. United States Treasury Obligations are used routinely to collateralize OTC derivative positions, and are deposited routinely as margin to collateralize futures positions. The Fund may liquidate United States Treasury Obligations to meet an initial or variation margin requirement.

Performance Summary

This Report covers the three months ended September 30, 2011 and 2010 (hereinafter referred to as the “Three Months Ended September 30, 2011” and the “Three Months Ended September 30, 2010”, respectively) and the nine months ended September 30, 2011 and 2010 (hereinafter referred to as the “Nine Months Ended September 30, 2011” and the “Nine Months Ended September 30, 2010”, respectively). The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC (the “NYSE Alternext”)) on January 5, 2007, and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

Performance of the Fund and the exchange traded Shares are detailed below in “Results of Operations”. Past performance of the Fund and the exchange traded Shares are not necessarily indicative of future performance.

The Index is intended to reflect the change in market value of the Index Commodity. In turn, the Index is intended to reflect the silver sector. The DBIQ Optimum Yield Silver Index Total Return™ (the “DBIQ-OY SI TR™”) consists of the Index plus 3-month United States Treasury Obligations returns. (Because the Fund invested with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank Liquid Commodity Index- Optimum Yield Silver Excess Return™ (the “DBLCI-OY Silver ER™”) to December 31, 2010, references to the Deutsche Bank Liquid Commodity Index- Optimum Yield Silver Total Return™ (“DBLCI-OY TR™”) and DBIQ-OY SI TR™ have been included). Past Index results are not necessarily indicative of future changes, positive or negative, in the Index closing levels.

The section “Summary of the DBIQ-OY SI TR™ and Underlying Index Commodity Returns for the Three Months Ended September 30, 2011 and the Nine Months Ended September 30, 2011 and Summary of the DBLCI-OY Silver TR™ and Underlying Index Commodity Returns for the Three Months Ended September 30, 2010 and the Nine Months Ended September 30, 2010” below provides an overview of the changes in the closing levels of the DBIQ-OY SI TR™ and DBLCI-OY Silver TR™ by disclosing the change in market value of the underlying component Index Commodity through a “surrogate” (and analogous) index plus 3-month United States Treasury Obligations returns. Please note also that the Fund’s objective is to track the Index (not the DBIQ-OY SI TR™ or the DBLCI-OY Silver TR™), and the Fund does not attempt to outperform or underperform the Index. The Index employs the optimum yield roll method with the objective of mitigating the negative effects of contango, the condition in which distant delivery prices for futures exceed spot prices, and maximizing the positive effects of backwardation, a condition opposite of contango.

Summary of the DBIQ-OY SI TR™ and Underlying Index Commodity Returns for the Three Months Ended September 30, 2011 and the Nine Months Ended September 30, 2011 and Summary of the DBLCI-OY SI TR™ and Underlying Index Commodity Returns for the Three Months Ended September 30, 2010 and the Nine Months Ended September 30, 2010

* From January 3, 2007 to December 31, 2010, the Fund invested with a view to tracking changes, whether positive or negative, in the level of the Deutsche Bank Liquid Commodity Index- Optimum Yield Silver Excess Return™. During this same period, the Fund did not track the changes in closing levels of DBIQ–OY SI ER™.

If the Fund’s interest income from its holdings of fixed income securities were to exceed the Fund’s fees and expenses, the aggregate return on an investment in the Fund is expected to outperform the Index and underperform the DBIQ-OY SI TR™. The only difference between (i) the Index and (ii) the DBIQ-OY SI TR™ is that the Index do not include interest income from a hypothetical basket of fixed income securities while the DBIQ-OY SI TR™ does include such a component. Thus, the difference between the Index and the DBIQ-OY SI TR™ is attributable entirely to the hypothetical interest income from this hypothetical basket of fixed income securities. If the Fund’s interest income from its holdings of fixed income securities exceeds the Fund’s fees and expenses, then the amount of such excess is expected to be distributed periodically. The market price of the Shares is expected to closely track the Index. The aggregate return on an investment in the Fund over any period is the sum of the capital appreciation or depreciation of the Shares over the period plus the amount of any distributions during the period. Consequently, the Fund’s aggregate return is expected to outperform the Index by the amount of the excess, if any, of its interest income over its fees and expenses but, as a result of the Fund’s fees and expenses, the aggregate return on the Fund is expected to underperform the DBIQ-OY SI TR™. If the Fund’s fees and expenses were to exceed the Fund’s interest income from its holdings of fixed income securities, the aggregate return on an investment in the Fund is expected to underperform the Index.

Net Asset Value

Net asset value means the total assets of the Fund, including, but not limited to, all futures, cash and investments less total liabilities of the Fund, each determined on the basis of U.S. generally accepted accounting principles, consistently applied under the accrual method of accounting. In particular, net asset value includes any unrealized appreciation or depreciation on open commodity futures contracts, and any other credit or debit accruing to the Fund but unpaid or not received by the Fund. All open commodity futures contracts will be calculated at their then current market value, which will be based upon the settlement price for that particular commodity futures contract traded on the applicable exchange on the date with respect to which net asset value is being determined; provided, that if a commodity futures contract could not be liquidated on such day, due to the operation of daily limits or other rules of the exchange upon which that position is traded or otherwise, the Managing Owner may value such futures contract pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. The Managing Owner may in its discretion (and under 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 or man-made disaster, act of God, armed conflict, act of terrorism, riot or labor disruption or any similar intervening circumstance) value any asset of the 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 the Fund’s brokerage account is accrued monthly. The amount of any distribution is a liability of the Fund from the day when the distribution is declared until it is paid.

20

Critical Accounting Policies

The Fund’s critical accounting policies are as follows:

Preparation of the financial statements and related disclosures in conformity with U.S. generally accepted accounting principles requires the application of appropriate accounting rules and guidance, as well as the use of estimates, and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expense and related disclosure of contingent assets and liabilities during the reporting period of the financial statements and accompanying notes. The financial statements of the Fund include the consolidated financial statements of the Fund and Master Fund when applicable. As described above, the Fund was originally formed as a master-feeder structure and such structure was collapsed on December 31, 2010. The financial statements reflect consolidation of the Fund and the Master Fund for all periods prior to December 31, 2010. The Fund’s application of these policies involves judgments and actual results may differ from the estimates used.

The Fund holds a significant portion of its assets in futures contracts and United States Treasury Obligations, both of which are recorded on a trade date basis and at fair value in the financial statements, with changes in fair value reported in the statement of income and expenses.

The use of fair value to measure financial instruments, with related unrealized gains or losses recognized in earnings in each period is fundamental to the Fund’s financial statements. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).

In determining fair value of United States Treasury Obligations and commodity futures contracts, the Fund uses unadjusted quoted market prices in active markets. FASB fair value measurement and disclosure guidance requires a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The objective of a fair value measurement is to determine the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). The hierarchy gives the highest priority to unadjusted quoted prices for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. See Note 4(c) within the financial statements in Item 1 for further information.

When market closing prices are not available, the Managing Owner may value an asset of the Fund pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards.

Realized gains (losses) and changes in unrealized gain (loss) on open positions are determined on a specific identification basis and recognized in the statement of income and expenses in the period in which the contract is closed or the changes occur, respectively.

Interest income on United States Treasury Obligations is recognized on an accrual basis when earned. Premiums and discounts are amortized or accreted over the life of the United States Treasury Obligations.

Market Risk

Trading in futures contracts involves the Fund entering into contractual commitments to purchase a particular commodity at a specified date and price. The market risk associated with the Fund’s commitments to purchase commodities is limited to the gross or face amount of the contracts held.

The Fund’s exposure to market risk is also influenced by a number of factors including the volatility of interest rates and foreign currency exchange rates, the liquidity of the markets in which the contracts are traded and the relationships among the contracts held. The inherent uncertainty of the Fund’s trading as well as the development of drastic market occurrences could ultimately lead to a loss of all or substantially all of the investors’ capital.

Credit Risk

When the Fund enters into futures contracts, the Fund is exposed to credit risk that the counterparty to the contract will not meet its obligations. The counterparty for futures contracts traded on United States and on most foreign futures exchanges is the clearing house associated with the particular exchange. In general, clearing houses are backed by their corporate members who may be required to share in the financial burden resulting from the nonperformance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearing house is not backed by the clearing members (i.e.some foreign exchanges), it may be backed by a consortium of banks or other financial institutions. There can be no assurance that any counterparty, clearing member or clearinghouse will meet its obligations to the Fund.

The Commodity Broker, when acting as the Fund’s futures commission merchant in accepting orders for the purchase or sale of domestic futures contracts, is required by CFTC regulations to separately account for and segregate as belonging to the Fund all assets of the Fund relating to domestic futures trading and the Commodity Broker is not allowed to commingle such assets with other assets

21

of the Commodity Broker. In addition, CFTC regulations also require the Commodity Broker to hold in a secure account assets of the Fund related to foreign futures trading.

Liquidity

All of the Fund’s source of capital is derived from the Fund’s offering of Shares to Authorized Participants. The Fund in turn allocates its net assets to commodities trading. A significant portion of the net asset value is held in United States Treasury Obligations and cash, which is used as margin for the Fund’s trading in commodities. The percentage that United States Treasury Obligations bear to the total net assets will vary from period to period as the market values of the Fund’s commodity interests change. The balance of the net assets is held in the Fund’s commodity trading account. Interest earned on the Fund’s interest-bearing funds is paid to the Fund.

The Fund’s commodity contracts may be subject to periods of illiquidity because of market conditions, regulatory considerations or for other reasons. For example, commodity exchanges generally have the ability to limit fluctuations in certain commodity futures contract prices during a single day by regulations referred to as “daily limits.” During a single day, no trades may be executed at prices beyond the daily limit. Once the price of a particular futures contract has increased or decreased by an amount equal to the daily limit, positions in the commodity futures contract can neither be taken nor liquidated unless the traders are willing to effect trades at or within the limit. Commodity futures prices have occasionally moved the daily limit for several consecutive days with little or no trading. Such market conditions could prevent the Fund from promptly liquidating its commodity futures positions.

Because the Fund trades futures contracts, its capital is at risk due to changes in the value of futures contracts (market risk) or the inability of counterparties (including exchange clearinghouses) to perform under the terms of the contracts (credit risk).

Authorized Participants may also redeem Baskets of Shares. On any business day, an Authorized Participant may place an order with the Managing Owner to redeem one or more Baskets. Redemption orders must be placed by 10:00 a.m., New York time. The day on which the Managing Owner receives a valid redemption order is the redemption order date. Redemption orders are irrevocable. The redemption procedures allow only Authorized Participants to redeem Baskets. Individual Shareholders may not redeem directly from the Fund. By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through DTC’s book-entry system to the Fund no later than noon, New York time, on the business day immediately following 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 the non-refundable transaction fee due for the redemption order.

Cash Flows

The primary cash flow activity of the Fund is to raise capital from Authorized Participants through the issuance of Shares. This cash is used to invest in United States Treasury Obligations and to meet margin requirements as a result of the positions taken in futures contracts to match the fluctuations of the Index the Fund is tracking.

Operating Activities

Net cash flow provided by and (used for) operating activities was $142.2 million and $20.5 million for the Nine Months Ended September 30, 2011 and 2010, respectively. This amount primarily includes net purchases and sales of United States Treasury Obligations which are held at fair value on the statement of financial condition.

During the Nine Months Ended September 30, 2011, $668.4 million was paid to purchase United States Treasury Obligations and $746.5 million was received from sales and maturing contracts. During the Nine Months Ended September 30, 2010, $232.4 million was paid to purchase United States Treasury Obligations and $250.5 million was received from sales and maturing contracts. Unrealized appreciation on United States Treasury Obligations and futures decreased by $74.4 million and increased by $19.8 million during the Nine Months Ended September 30, 2011 and 2010, respectively.

Financing Activities

The Fund’s net cash flow provided by and (used for) financing activities was $(40.2) million and $(25.0) million during the Nine Months Ended September 30, 2011 and 2010, respectively. This included $244.3 million and $57.3 million from the sale of Shares to Authorized Participants during the Nine Months Ended September 30, 2011 and September 30, 2010, respectively.

Results of Operations

FOR THE THREE MONTHS ENDED SEPTEMBER 30, 2011 AND 2010 AND THE NINE MONTHS ENDED SEPTEMBER 30, 2011 AND 2010

The Fund was launched on January 3, 2007 at $25.00 per Share. The Shares traded on the NYSE Alternext from January 5, 2007 to November 25, 2008 and have been trading on the NYSE Arca since November 25, 2008.

The Fund seeks to track changes in the closing levels of the DBIQ Optimum Yield Silver Index Excess Return™ (the “DBIQ-OY SI ER™”, or the “Index”) over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. The following graphs illustrate changes in (i) the price of the Shares (as reflected by the graph “DBS”), (ii) the Fund’s NAV (as reflected by the graph “DBSNV”), and (iii) the closing levels of the Index (as reflected by the graph “DBSLIX”). Whenever the interest income earned by the Fund exceeds Fund expenses, the price of the Shares generally has exceeded the levels of the Index primarily because the Share price reflects interest income from the Fund’s collateral holdings whereas the Index does not consider such interest income. There can be no assurances that the price of the Shares will exceed the Index levels.

The Index is a set of rules applied to a body of data and does not represent the results of actual investment or trading. The Index is frictionless, in that it does not take into account fees or expenses associated with investing in the Fund. Also, because it does not represent actual futures positions, the Index is not subject to, and does not take into account the impact of, speculative position limits or certain other similar limitations on the ability of the Fund to trade the Index Commodity. The “TR” version of the Index includes an assumed amount of interest income based on prevailing rates that is adjusted from time to time. The Fund, by contrast, invests actual money and trades actual futures contracts. As a result, the performance of the Fund involves friction, in that fees and expenses impose a drag on performance. The Fund may be subject to speculative position limits and certain other limitations on its ability to trade the Index Commodity, which may compel the Fund to trade futures or other instruments that are not the Index Commodity as proxies for the Index Commodity. The interest rate actually earned by the Fund over any period may differ from the assumed amount of interest income factored into the “TR” version of the Index over the same period. All of these factors can contribute to discrepancies between changes in net asset value per Share and changes in the level of the Index over any period of time. Fees and expenses always will tend to cause changes in the net asset value per Share to underperform changes in the value of the Index over any given period, all other things being equal. Actual interest income could be higher or lower than the assumed interest income factored into the “TR” version of the Index, and therefore could cause changes in the net asset value per Share to outperform or underperform changes in the value of the “TR” version of the Index over any given period, all other things being equal. Similarly, trading futures or other instruments that are not the Index Commodity as proxies for the Index Commodity could cause changes in the net asset value per Share to outperform or underperform changes in the value of the Index over any given period, all other things being equal.

DBIQ Optimum Yield Silver Index Excess Return™ is an index and does not reflect (i) actual trading and (ii) any fees or expenses.

WHILE THE FUND’S OBJECTIVE IS NOT TO GENERATE PROFIT THROUGH ACTIVE PORTFOLIO MANAGEMENT, BUT IS TO TRACK THE INDEX, BECAUSE THE INDEX WAS ESTABLISHED IN OCTOBER 2010, CERTAIN INFORMATION RELATING TO THE INDEX CLOSING LEVELS MAY BE CONSIDERED TO BE “HYPOTHETICAL.” HYPOTHETICAL INFORMATION MAY HAVE CERTAIN INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW.

WITH RESPECT TO INDEX DATA, NO REPRESENTATION IS BEING MADE THAT THE INDEX WILL OR IS LIKELY TO ACHIEVE ANNUAL OR CUMULATIVE CLOSING LEVELS CONSISTENT WITH OR SIMILAR TO THOSE SET FORTH HEREIN. SIMILARLY, NO REPRESENTATION IS BEING MADE THAT THE FUND WILL GENERATE PROFITS OR LOSSES SIMILAR TO THE FUND’S PAST PERFORMANCE OR THE HISTORICAL ANNUAL OR CUMULATIVE CHANGES IN THE INDEX CLOSING LEVELS. IN FACT, THERE ARE FREQUENTLY SHARP DIFFERENCES BETWEEN HYPOTHETICAL RESULTS AND THE ACTUAL RESULTS SUBSEQUENTLY ACHIEVED BY INVESTMENT METHODOLOGIES, WHETHER ACTIVE OR PASSIVE.

WITH RESPECT TO INDEX DATA, ONE OF THE LIMITATIONS OF HYPOTHETICAL INFORMATION IS THAT IT IS GENERALLY PREPARED WITH THE BENEFIT OF HINDSIGHT. TO THE EXTENT THAT INFORMATION PRESENTED HEREIN RELATES TO THE PERIOD DECEMBER 1988 THROUGH SEPTEMBER 2010, THE INDEX CLOSING LEVELS REFLECT THE APPLICATION OF THE INDEX’S METHODOLOGY, AND SELECTION OF INDEX COMMODITY, IN HINDSIGHT.

NO HYPOTHETICAL RECORD CAN COMPLETELY ACCOUNT FOR THE IMPACT OF FINANCIAL RISK IN ACTUAL TRADING. FOR EXAMPLE, THERE ARE NUMEROUS FACTORS, INCLUDING THOSE DESCRIBED UNDER ITEM 1A. “RISK FACTORS” SET FORTH IN THE FUND’S ANNUAL REPORT ON FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 2010, RELATED TO THE COMMODITIES MARKETS IN GENERAL OR TO THE IMPLEMENTATION OF THE FUND’S EFFORTS TO TRACK THE INDEX OVER TIME WHICH CANNOT BE, AND HAVE NOT BEEN, ACCOUNTED FOR IN THE PREPARATION OF THE INDEX INFORMATION SET FORTH ON THE FOLLOWING PAGES, ALL OF WHICH CAN ADVERSELY AFFECT ACTUAL PERFORMANCE RESULTS FOR THE FUND. FURTHERMORE, THE INDEX INFORMATION DOES NOT INVOLVE FINANCIAL RISK OR ACCOUNT FOR THE IMPACT OF FEES AND COSTS ASSOCIATED WITH THE FUND.

Off-Balance Sheet Arrangements and Contractual Obligations

In the normal course of its business, the Fund is a party to financial instruments with off-balance sheet risk. The term “off-balance sheet risk” refers to an unrecorded potential liability that, even though it does not appear on the balance sheet, may result in a future obligation or loss. The financial instruments used by the Fund are commodity futures, whose values are based upon an underlying asset and generally represent future commitments which have a reasonable possibility to be settled in cash or through physical delivery. The financial instruments are traded on an exchange and are standardized contracts.

The Fund has not utilized, nor does it expect to utilize in the future, special purpose entities to facilitate off-balance sheet financing arrangements and has no loan guarantee arrangements or off-balance sheet arrangements of any kind, other than agreements entered into in the normal course of business noted above, which may include indemnification provisions related to certain risks service providers undertake in performing services which are in the best interests of the Fund. While the Fund’s exposure under such indemnification provisions cannot be estimated, these general business indemnifications are not expected to have a material impact on the Fund’s financial position.

The Fund’s contractual obligations are with the Managing Owner and the Commodity Broker. Management Fee payments made to the Managing Owner are calculated as a fixed percentage of the Fund’s net asset value. Commission payments to the Commodity Broker are on a contract-by-contract, or round-turn, basis. As such, the Managing Owner cannot anticipate the amount of payments

27

that will be required under these arrangements for future periods as net asset values are not known until a future date. These agreements are effective for one-year terms, renewable automatically for additional one-year terms unless terminated. Additionally, these agreements may be terminated by either party for various reasons.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

INTRODUCTION

The Fund is designed to replicate positions in a commodity index. The market sensitive instruments held by it are subject to the risk of trading loss. Unlike an operating company, the risk of market sensitive instruments is integral, not incidental, to the Fund’s main line of business.

Market movements can produce frequent changes in the fair market value of the Fund’s open positions and, consequently, in its earnings and cash flow. The Fund’s market risk is primarily influenced by changes in the price of commodities.

Standard of Materiality

Materiality as used in this section, “Quantitative and Qualitative Disclosures About Market Risk,” is based on an assessment of reasonably possible market movements and the potential losses caused by such movements, taking into account the effects of margin, and any other multiplier features, as applicable, of the Fund’s market sensitive instruments.

QUANTIFYING THE FUND’S TRADING VALUE AT RISK

Quantitative Forward-Looking Statements

The following quantitative disclosures regarding the Fund’s market risk exposures contain “forward-looking statements” within the meaning of the safe harbor from civil liability provided for such statements by the Private Securities Litigation Reform Act of 1995 (set forth in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934). All quantitative disclosures in this section are deemed to be forward-looking statements for purposes of the safe harbor, except for statements of historical fact (such as the dollar amount of maintenance margin required for market risk sensitive instruments held at the end of the reporting period).

Value at risk, or VaR, is a statistical measure of the value of losses that would not be expected to be exceeded over a given time horizon and at a given probability level arising from movement of underlying risk factors. Loss is measured as a decline in the fair value of the portfolio as a result of changes in any of the material variables by which fair values are determined. VaR is measured over a specified holding period (1 day) and to a specified level of statistical confidence (99th percentile). However, the inherent uncertainty in the markets in which the Fund trades and the recurrence in the markets traded by the Fund of market movements far exceeding expectations could result in actual trading or non-trading losses far beyond the indicated VaR or the Fund’s experience to date (i.e., “risk of ruin”). In light of this, as well as the risks and uncertainties intrinsic to all future projections, the inclusion of the quantification included in this section should not be considered to constitute any assurance or representation that the Fund’s losses in any market sector will be limited to VaR or by the Fund’s attempts to manage its market risk.

THE FUND’S TRADING VALUE AT RISK

The Fund calculates VaR using the actual historical market movements of the Fund’s total assets.

The following table indicates the trading VaR associated with the Fund’s total assets as of September 30, 2011.

Description	Total Assets		Daily Volatility			VaR* (99 Percentile)		Number of times VaR Exceeded
PowerShares DB Silver Fund	$	157,362,630		1.35	%	$	10,827,252		4

The following table indicates the trading VaR associated with the Fund’s total assets as of December 31, 2010.

Description	Total Assets		Daily Volatility			VaR* (99 Percentile)		Number of times VaR Exceeded
PowerShares DB Silver Fund	$	207,694,990		1.37	%	$	9,681,708		2

* The VaR represents the one day downside risk, under normal market conditions, with a 99% confidence level. It is calculated using historical market moves of the Fund’s total assets and uses a one year look-back.

28

NON-TRADING RISK

The Fund has non-trading market risk as a result of investing in short-term United States Treasury Obligations. The market risk represented by these investments is expected to be immaterial.

QUALITATIVE DISCLOSURES REGARDING PRIMARY TRADING RISK EXPOSURES

The following qualitative disclosures regarding the Fund’s market risk exposures—except for those disclosures that are statements of historical fact—constitute forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. The Fund’s primary market risk exposures are subject to numerous uncertainties, contingencies and risks. Government interventions, defaults and expropriations, illiquid markets, the emergence of dominant fundamental factors, political upheavals, changes in historical price relationships, an influx of new market participants, increased regulation and many other factors could result in material losses as well as in material changes to the risk exposures of the Fund. There can be no assurance that the Fund’s current market exposure will not change materially. Investors may lose all or substantially all of their investment in the Fund.

The primary trading risk exposure of the Fund as of September 30, 2011 relating to the Index Commodity is as follows:

Silver

The price of silver is volatile and is affected by numerous factors. The largest industrial users of silver (e.g., photographic, jewelry, and electronic industries) may influence its price. A change in economic conditions, such as a recession, can adversely affect industries which are significant users of silver. In turn, such a negative economic impact may decrease demand for silver, and, consequently, its price. Worldwide speculation and hedging activity by silver producers may also impact its price.

QUALITATIVE DISCLOSURES REGARDING NON-TRADING RISK EXPOSURE

General

The Fund is unaware of any (i) anticipated known demands, commitments or capital expenditures; (ii) material trends, favorable or unfavorable, in its capital resources; or (iii) trends or uncertainties that will have a material effect on operations.

QUALITATIVE DISCLOSURES REGARDING MEANS OF MANAGING RISK EXPOSURE

Under ordinary circumstances, the Managing Owner’s discretionary power is limited to determining whether the Fund will make a distribution. Under emergency or extraordinary circumstances, the Managing Owner’s discretionary powers increase, but remain circumscribed. These special circumstances, for example, include the unavailability of the Index or certain natural or man-made disasters. The Managing Owner does not apply risk management techniques. The Fund initiates positions only on the “long” side of the market and does not employ “stop-loss” techniques.

ITEM 4. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the management of the Managing Owner, including Hans Ephraimson, its Chief Executive Officer, and Michael Gilligan, its Principal Financial Officer, the Fund carried out an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this quarterly report, and, based upon that evaluation, Hans Ephraimson, the Chief Executive Officer, and Michael Gilligan, the Principal Financial Officer, of the Managing Owner, concluded that the Fund’s disclosure controls and procedures were effective to ensure that information the Fund is required to disclose in the reports that it files or submits with the Securities and Exchange Commission (the “SEC”) under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and to ensure that information required to be disclosed by the Fund in the reports that it files or submits under the Exchange Act is accumulated and communicated to management of the Managing Owner, including its Chief Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There has been no change in internal control over financial reporting (as defined in the Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the Fund’s last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Fund’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

Not Applicable.

Item 1A. Risk Factors.

There are no material changes from risk factors as previously disclosed in the Annual Report on Form 10-K for the year ended December 31, 2010, filed March 14, 2011 except for the following:

(3) Regulatory and Exchange Position Limits and Other Rules May Restrict the Creation of Baskets and the Operation of the Fund.

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

The purposes of speculative position limits are to diminish, eliminate or prevent sudden or unreasonable fluctuations or unwarranted changes in the prices of futures contracts. As of the date of this Report, the CFTC and commodity exchange rules impose speculative position limits on market participants trading in the Index Commodity included in the Index (Silver, the “Affected Index Commodity”). Currently, speculative position limits (i) for corn, oats, wheat, soybean, soybean oil and cotton are determined by the CFTC and (ii) for all other commodities are determined by the futures exchanges. Pursuant to the statutory mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, which was signed into law on July 21, 2010, the CFTC proposed regulations in January 2011, or the Proposed Regulations, would, in pertinent part, impose new federal position limits on futures and options on a subset of energy, metal, and agricultural commodities, or the Referenced Contracts, and economically equivalent swaps. The Index Commodity is a Referenced Contract subject to the 2011 Proposed Rules.

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

Under current regulations, subject to any relevant exemptions, traders, such as the Fund, may not exceed speculative position limits, either individually or in the aggregate with other persons with whom they are under common control or ownership. Under the Proposed Regulations, the CFTC would require certain persons to aggregate exchange listed futures and economically equivalent swap positions owned or controlled by such persons.

Affected Index Commodity	Exchange (Symbol)1	Exchange Position Limits2
Silver	COMEX (SI)	1,500 – Spot Month 6,000 – Single Month 6,000 – All Months Combined

¹ Legend:

“COMEX” means the Commodity Exchange Inc., New York, or its successor.

² Subject to the Position Limit, Position Accountability and Reportable Level table in the Interpretations & Special Notices section at the end of Chapter 5 of the exchange’s rulebook.

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

Under the Dodd-Frank Act, the CFTC is required, among other things, to establish speculative position limits on exchange listed futures and options on physical commodities (including certain energy, metals and agricultural products) and economically equivalent over-the-counter derivatives. The Dodd-Frank Act will also require the CFTC to establish aggregate position limits for contracts based on the same underlying commodity, including certain contracts traded on non-U.S. exchanges. Depending on the outcome of the

30

Proposed Regulations and any future CFTC or futures exchange rulemaking, as applicable, the rules concerning position limits may be amended in a manner that is detrimental to the Fund. For example, if the amended rules are detrimental to the Fund, its ability to issue new Baskets, or reinvest income in additional futures contracts corresponding to the Affected Index Commodity, may be limited to the extent these activities would cause the Fund to exceed the applicable position limits. Limiting the size of the Fund may affect the correlation between the price of the Shares, as traded on the NYSE Arca, and the net asset value of the Fund. That is, the inability to create additional Baskets could result in Shares in the Fund trading at a premium or discount to net asset value of the Fund.

(27) The Effect Of Market Disruptions and Government Intervention Are Unpredictable And May Have An Adverse Effect On The Value Of Your Shares.

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

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

(28) Regulatory Changes or Actions, Including the Implementation of the Dodd-Frank Act, May Alter the Operations and Profitability of the Fund.

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

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(a) There have been no unregistered sales of the Fund’s securities. No Fund securities are authorized for issuance by the Fund under equity compensation plans.
