The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC (the “NYSE Alternext”)) on February 3, 2006 and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

This Report covers the three months ended March 31, 2014 and 2013 (hereinafter referred to as the “Three Months Ended March 31, 2014” and the “Three Months Ended March 31, 2013”, respectively).

The accompanying unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Fund’s financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the SEC on March 3, 2014.

(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 Diversified Commodity Index Excess Return™ (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 commodity sector. The commodities comprising the Index are Light Sweet Crude Oil, Heating Oil, Aluminum, Gold, Corn, Wheat, Brent Crude, Copper Grade A, Natural Gas, RBOB Gasoline, Silver, Soybeans, Sugar and Zinc (the “Index Commodities”).

The Commodity Futures Trading Commission (the “CFTC”) and/or commodity exchanges, as applicable, impose position limits on market participants trading in certain commodities futures contracts included in the Index. The Index is comprised of futures contracts on each of the Index Commodities 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 any Index Commodity by investing in a specific Index Contract, the Fund may invest in a futures contract referencing the particular Index Commodity other than the Index Contract or, in the alternative, invest in other futures contracts not based on the particular Index Commodity if, in the commercially reasonable judgment of the Managing Owner, such futures contracts tend to exhibit trading prices that correlate with such Index Commodity. Because the Fund is approaching or has reached position limits with respect to certain futures contracts comprising the Index, the Fund has commenced investing in other futures contracts based on commodities that comprise the Fund’s Index and in futures contracts based on commodities other than commodities that comprise the Fund’s Index.

The Fund has been subject to accountability levels with respect to both light sweet crude oil (WTI) and RBOB Gasoline, each of which are index futures contracts that are listed on the NYMEX. As a result of reaching the accountability levels with respect to light sweet crude oil (WTI), the Fund invested in the ICE West Texas Intermediate Light Sweet Crude Oil futures contracts with comparable expirations during the period from January 2, 2013 to June 3, 2013. As a result of reaching the accountability levels with respect to RBOB Gasoline, the Fund invested in the next sequential expiring RBOB Gasoline futures contract also listed on the NYMEX during the period from January 2, 2013 and continued to maintain its positions in such contracts as of September 30, 2013.

During the period from December 12, 2012 to June 10, 2013, the Managing Owner was ordered by the Market Regulation Department of the NYMEX to no longer increase, on either an intraday or end of day basis, the Fund’s net positions in RBOB Gasoline futures contracts. Such order was retracted effective June 10, 2013.

(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.

In June 2013, the FASB issued updated guidance clarifying the characteristics of an investment company and requiring new disclosures. Under the guidance, all entities regulated under the Investment Company Act of 1940 automatically qualify as investment companies, while all other entities need to consider both the fundamental and typical characteristics of an investment company in determining whether they qualify as investment companies. This new guidance is effective for interim or annual reporting periods that begin after December 15, 2013, and should be applied prospectively. The Fund adopted this guidance effective January 1, 2014. The Fund has determined that it meets the definition of an investment company and has prepared the unaudited financial statements in conformity with generally accepted accounting principles in the United States of America for investment companies. The adoption of this guidance had no effect on the Fund’s unaudited statements of financial condition, including the schedule of investments, and the related unaudited statements of income and expenses, changes in shareholders’ equity and of cash flows.

(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. There were no significant estimates used in the preparation of these financial statements. The brokerage agreement with the Commodity Broker provides for the net settlement of all financial instruments covered by the agreement in the event of default or termination of any one contract.

(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). The brokerage agreement with the Commodity Broker provides for the net settlement of all financial instruments covered by the agreement in the event of default or termination of any one contract.

Financial Accounting Standards Board (FASB) Accounting Standards Codification 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.

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 non-LME commodity futures contracts, the Fund uses unadjusted quoted market prices in active markets. United States Treasury Obligations and non-LME 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.

In determining fair value of LME commodity futures contracts, the Fund uses valuation pricing based on action of a committee that incorporates prices from the most liquid trading sessions of the day and can also rely on other inputs such as trades, bids and offers (including indicative bids and offers) transacted throughout the whole day. During the year ended December 31, 2013, management changed the classification of LME commodity futures from Level 1 to Level 2.

Assets and Liabilities Measured at Fair Value as of March 31, 2014 were as follows:

	Level 1		Level 2			Total
United States Treasury Obligations	$	6,546,792,463		—		$	6,546,792,463
Commodity Futures Contracts	$	132,380,891	$	(15,925,413	)	$	116,455,478

Assets and Liabilities Measured at Fair Value as of December 31, 2013 were as follows:

	Level 1		Level 2			Total
United States Treasury Obligations	$	6,639,612,594		—		$	6,639,612,594
Commodity Futures Contracts	$	56,755,799	$	(19,503,125	)	$	37,252,674

There were no Level 3 holdings during the quarter ended March 31, 2014 and the year ended December 31, 2013. Futures contracts in a net depreciation position of 19,503,125 were transferred from Level 1 to Level 2 during the year ended December 31, 2013 as described above.

(d) Deposits with Commodity Broker

The Fund deposits cash and United States Treasury Obligations with its Commodity Broker subject to CFTC regulations and various exchange and Commodity 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 Commodity 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 in interest income over the life of the United States Treasury Obligations. The Fund purchased $1,023,000,000 face amount of United States Treasury Obligations which was recorded as a payable as of March 31, 2014. As a result, a payable for securities purchased is reported for $1,022,896,563. The Fund purchased $1,089,000,000 face amount of United States Treasury Obligations which was recorded as a payable as of December 31, 2013. As a result, a payable for securities purchased is reported for $1,088,821,071.

(f) Cash Held by Commodity 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 March 31, 2014 the Fund had $25,206,833 of cash held with the Commodity Broker. As of December 31, 2013 the Fund had cash held by the Commodity Broker of $123,072,778. As of March 31, 2014 and December 31, 2013 there were no cash equivalents held by the Fund.

(g) Receivable/(Payable) for LME Contracts

The Fund trades aluminum, copper and zinc commodity future contracts on the London Metals Exchange (“LME”). For settlement of futures contracts traded on the LME, cash is not transferred until the settled futures contracts expire. As of March 31, 2014, the Fund had a payable to the Commodity Broker for contracts on the LME of $6,663,044 related to net realized losses on LME contracts. As of December 31, 2013, the Fund had a payable to the Commodity Broker of $10,356,375 related to net realized losses on LME contracts which have been closed out but the contract is not yet expired.

(h) 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, 2009.

(i) Futures Contracts

All commodity futures contracts are held and used for trading purposes. Commodity futures contracts 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 contracts 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. For the quarters ended March 31, 2014 and 2013, the average notional market value of futures contracts held was $5.8 billion and $7.0 billion, respectively.

The Fair Value of Derivative Instruments is as follows:

Derivatives not Accounted for as Hedging Instruments	Statements of Financial Condition Location	Net Unrealized Appreciation / (Depreciation) at March 31, 2014		Net Unrealized Appreciation / (Depreciation) at December 31, 2013
Commodity Futures Contracts	Net Unrealized Appreciation (Depreciation) on Futures Contracts	$	116,455,478	$	37,252,674

The Effect of Derivative Instruments on the Statements of Income and Expenses is as follows:

		For the Three Months Ended March 31, 2014				For the Three Months Ended March 31, 2013
Derivatives not Accounted for as Hedging Instruments	Location of Gain or (Loss) on Derivatives Recognized in Income	Realized Gain or (Loss) on Derivatives Recognized in Income		Change in Unrealized Gain or (Loss) on Derivatives Recognized in Income		Realized Gain or (Loss) on Derivatives Recognized in Income		Change in Unrealized Gain or (Loss) on Derivatives Recognized in Income
Commodity Futures Contracts	Net Realized Gain (Loss) on Futures	$	37,969,343		—	$	15,731,107		—
	Net Change in Unrealized Gain (Loss) on Futures		—	$	79,202,804		—	$	(103,327,228	)

The Fund utilizes derivative instruments to achieve each Fund’s investment objective. For financial reporting purposes, the Fund offsets financial assets and financial liabilities that are subject to master netting arrangements or similar agreements in the statement of financial condition. The following table presents the gross and net amounts of these assets and liabilities with any offsets to reflect the Funds’ ability to reflect the master netting agreements at March 31, 2014:

								Gross Amounts Not Offset in the Statement of Financial Condition
Assets	Gross Amount of Recognized Assets		Gross Amounts Offset in the Statement of Financial Condition			Net Amounts of Assets Presented in the Statement of Financial Condition		Financial Instruments		Cash Collateral Pledged		Net Amount
Commodity Futures Contracts	$	184,076,678	$	(67,621,200	)	$	116,455,478	$	—	$	—	$	116,455,478

The following table presents the gross and net amounts of these assets and liabilities with any offsets to reflect the Funds’ ability to reflect the master netting agreements at December 31, 2013:

								Gross Amounts Not Offset in the Statement of Financial Condition
Assets	Gross Amount of Recognized Assets		Gross Amounts Offset in the Statement of Financial Condition			Net Amounts of Assets Presented in the Statement of Financial Condition		Financial Instruments		Cash Collateral Pledged		Net Amount
Commodity Futures Contracts	$	177,990,530	$	(140,737,856	)	$	37,252,674	$	—	$	—	$	37,252,674

The Managing Owner will utilize the cash held at the commodity broker to offset any realized losses incurred in the commodity futures contracts, if available. To the extent that cash held at the commodity broker is not adequate to cover any realized losses, a portion of the United States Treasury Bills will be sold to make additional cash available.

(j) Brokerage Commissions and Fees

The Fund incurs all brokerage commissions, including applicable exchange fees, National Futures Association (“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 March 31, 2014 and 2013.

(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 are also paid by the Managing Owner.

(m) Non-Recurring Fees and Expenses

The Fund pays all non-recurring and unusual fees and expenses (referred to as extraordinary fees and expenses in the Trust Declaration), if any, of itself, as determined by the Managing Owner. Non-recurring and unusual fees and expenses are fees and expenses which are non-recurring and unusual in nature, such as legal claims and liabilities, litigation costs or indemnification or other unanticipated expenses. Such non-recurring and unusual fees and expenses, by their nature, are unpredictable in terms of timing and amount. For the Three Months Ended March 31, 2014 and 2013, the Fund did not incur such expenses.

(5) 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 in excess of the amounts shown in the Statement of Financial Condition. The financial instruments used by the Fund are exchange-listed 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.

13

PowerShares DB Commodity Index Tracking Fund

Notes to Unaudited Financial Statements—(Continued)

March 31, 2014

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 the Commodity Broker and/or 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 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 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. 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.

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.

(6) Share Purchases and Redemptions

(a) Purchases

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 3 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 the non-refundable transaction fee due for the creation order.

Unless otherwise agreed to by the Managing Owner and the Authorized Participant as provided in the next sentence, 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 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 3 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 the non-refundable transaction fee due for the creation order.

Creation orders may be placed either (i) through the Continuous Net Settlement (“CNS”) clearing processes of the National Securities Clearing Corporation (the “NSCC”) or (ii) if outside the CNS Clearing Process, only through the facilities of The Depository Trust Company (“DTC” or the “Depository”) (the “DTC Process”), or a successor depository.

(b) Redemptions

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 3 business days after the redemption order date. The redemption procedures allow Authorized Participants to redeem Baskets. Individual Shareholders may not redeem directly from the Fund. Instead, individual Shareholders may only redeem Shares in integral multiples of 200,000 and only through an Authorized Participant.

Unless otherwise agreed to by the Managing Owner and the Authorized Participant as provided in the next sentence, 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 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 3 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 the non-refundable transaction fee due for the redemption order.

March 31, 2014

Redemption orders may be placed either (i) through the CNS clearing processes of the NSCC or (ii) if outside the CNS Clearing Process, only through the DTC Process, or a successor depository, and only in exchange for cash. 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 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.

The redemption proceeds due from the 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.

(7) Profit and Loss Allocations and Distributions

Pursuant to the Trust Agreement, income and expenses are allocated pro rata to the Managing Owner as holder of the General Shares and to the Shareholders monthly based on their respective percentage interests as of the close of the last trading day of the 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 a pro rata basis in accordance with the respective capital balances of the shareholders.

No distributions were paid for the Three Months Ended March 31, 2014 or 2013.

(8) 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 March 31, 2014, no claims had been received by the Fund. Further, the Fund has not had prior claims or losses pursuant to these contracts. Accordingly, the Managing Owner expects the risk of loss to be remote.

(9) 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 March 31, 2014 and 2013. The net investment income and total expense ratios are calculated using average net asset value during the respective period. 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 at the date of each respective period presented.

Overview/Introduction

The Fund seeks to track changes, whether positive or negative, in the level of the DBIQ Optimum Yield Diversified Commodity Index Excess Return™ (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 certain commodities. The commodities comprising the Index are Light Sweet Crude Oil, Heating Oil, Aluminum, Gold, Corn, Wheat, Brent Crude, Copper Grade A, Natural Gas, RBOB Gasoline, Silver, Soybeans, Sugar and Zinc (the “Index Commodities”).

The Fund pursues its investment objective by investing in a portfolio of exchange-traded futures contracts in the Index Commodities. The notional amounts of each Index Commodity included in the Index are broadly in proportion to historic levels of the world’s production and stocks of the Index Commodities. 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.

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

The Index is intended to reflect the change in market value of certain commodities.

The Commodity Futures Trading Commission (the “CFTC”) and/or commodity exchanges, as applicable, impose position limits on market participants trading in certain commodities 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 any Index Commodity by investing in a specific Index Contract that is a part of the Index, the Fund may invest in a futures contract referencing the particular Index Commodity other than the Index Contract or, in the alternative, invest in other futures contracts not based on the particular Index Commodity if, in the commercially reasonable judgment of the Managing Owner, such futures contracts tend to exhibit trading prices that correlate with such Index Commodity. Because the Fund is approaching or has reached position limits with respect to certain futures contracts comprising the Index, the Fund has commenced investing in other futures contracts based on commodities that comprise the Fund’s Index and in futures contracts based on commodities other than commodities that comprise the Fund’s Index. Please see http://www.dbxus.com with respect to the most recently available weighted composition of the Fund and the composition of the Index on the Base Date.

Trademark applications in the United States are pending with respect to both the Fund and the Index. Any use of these trademarks must be with the consent of or under license from the Index Sponsor. The Fund and the Managing Owner have been licensed by the Index Sponsor to use the above noted trademarks. The Index Sponsor is an affiliate of the Fund and the Managing Owner.

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

17

The Index is rebalanced annually in November to ensure that each of the Index Commodities is weighted in the same proportion that such Index Commodities were weighted on September 3, 1997 (the “Base Date”). The Index has been calculated back to the Base Date. On the Base Date, the closing level was 100. The following table reflects the index base weights of each Index Commodity on the Base Date (the “Index Base Weights”):

Index Commodity	Index Base Weight (%)
Light Sweet Crude Oil		12.37
Heating Oil		12.37
RBOB Gasoline		12.37
Natural Gas		5.49
Brent Crude		12.37
Gold		8.00
Silver		2.00
Aluminum		4.17
Zinc		4.17
Copper Grade A		4.17
Corn		5.63
Wheat		5.63
Soybeans		5.63
Sugar		5.63
Closing Level on Base Date:		100.00

The following table reflects the Fund weights of each Index Commodity as of March 31, 2014:

Index Commodity	Fund Weight (%)
Light Sweet Crude Oil		12.76
Heating Oil		12.31
RBOB Gasoline		12.47
Natural Gas		6.31
Brent Crude		12.44
Gold		7.69
Silver		1.78
Aluminum		3.87
Zinc		4.10
Copper Grade A		3.74
Corn		5.77
Wheat		5.69
Soybeans		5.55
Sugar		5.52
Closing Level as of March 31, 2014		100.00

The Index Commodities are traded on the following futures exchanges: Light Sweet Crude Oil (WTI), Heating Oil, RBOB Gasoline and Natural Gas: New York Mercantile Exchange; Brent Crude: ICE Futures Europe; Gold and Silver: Commodity Exchange Inc., New York; Aluminum, Zinc and Copper Grade A: The London Metal Exchange Limited; Corn, Wheat and Soybeans: Board of Trade of the City of Chicago Inc.; and Sugar: ICE Futures U.S., Inc.

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

The Index includes provisions for the replacement of futures contracts as they approach maturity. This replacement takes place over a period of time in order to lessen the impact on the market for the futures contracts being replaced. With respect to each Index Commodity, the Fund employs a rule-based approach when it “rolls” from one futures contract to another. 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.” 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, each Index Commodity is able to potentially maximize the roll benefits in backwardated markets and minimize the losses from rolling in contangoed markets.

18

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

The DBIQ Optimum Yield Diversified Commodity Index Total Return™ and the Index are calculated in USD on both an excess return (unfunded) and total return (funded) basis.

The futures contract price for each Index Commodity will be the exchange closing price for such Index Commodity on each weekday when banks in New York, New York are open (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 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).

On the first New York business day (the “Verification Date”) of each month, each 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, 2014, and the Delivery Month of the Index Commodity futures contract currently in the Index is November 2014, a new Index Commodity futures contract with a later Delivery Month will be selected.

For each underlying Index Commodity in 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, 2014 and the Delivery Month of an Index Commodity futures contract currently in the Index is November 2014, the Delivery Month of an eligible new Index Commodity futures contract must be between December 2014 and October 2015. 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 each Index Commodity subject to a roll in that particular month unwinds the old futures contract and enters a position in the new futures contract. This takes place between the 2^nd and 6^th Index Business Day of the month.

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

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

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

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

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

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

The 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.

19

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, except in certain instances where midday variation margin calls are made. 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.

Position Limits and/or Accountability Levels

The Fund has been subject to accountability levels with respect to both light sweet crude oil (WTI) and RBOB Gasoline, each of which are index futures contracts that are listed on the NYMEX. As a result of reaching the accountability levels with respect to light sweet crude oil (WTI), the Fund invested in the ICE West Texas Intermediate Light Sweet Crude Oil futures contracts with comparable expirations during the period from January 2, 2013 to June 3, 2013. As a result of reaching the accountability levels with respect to RBOB Gasoline, the Fund invested in the next sequential expiring RBOB Gasoline futures contracts also listed on the NYMEX during the period from January 2, 2013 and continued to maintain its positions in such contracts as of September 30, 2013.

During the period from December 12, 2012 to June 10, 2013, the Managing Owner was ordered by the Market Regulation Department of the NYMEX to no longer increase, on either an intraday or end of day basis, the Fund’s net positions in RBOB Gasoline futures contracts. Such order was retracted effective June 10, 2013.

During the period from November 30, 2012 to January 25, 2013, the Managing Owner was ordered by the Market Regulation Department of the NYMEX to no longer increase, on either an intraday or end of day basis, the Fund’s net positions in light sweet crude oil (WTI) futures contracts. Such order was retracted effective January 25, 2013.

Performance Summary

This Report covers the three months ended March 31, 2014 and 2013 (hereinafter referred to as the “Three Months Ended March 31, 2014” and the “Three Months Ended March 31, 2013”, respectively).

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 Commodities. In turn, the notional amounts of each Index Commodity are broadly in proportion to historic levels of the world’s production and stocks of such Index Commodities. The DBIQ Optimum Yield Diversified Commodity Index Total Return ™, (the “DBIQ-OY Diversified TR™”) consists of the Index plus 3-month United States Treasury Obligations returns. 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 Diversified TR™ and Underlying Index Commodity Returns for the Three Months Ended March 31, 2014 and 2013” below provides an overview of the changes in the closing levels of DBIQ-OY Diversified TR™ by disclosing the change in market value of each 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

20

DBIQ-OY Diversified 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.

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 DBIQ-OY Diversified ER™ and underperform the DBIQ-OY Diversified TR™. The only difference between (i) the Index (the “Excess Return Index”) and (ii) the DBIQ-OY Diversified TR™ (the “Total Return Index”) is that the Excess Return Index does not include interest income from a hypothetical basket of fixed income securities while the Total Return Index does include such a component. Thus, the difference between the Excess Return Index and the Total Return Index 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 Excess Return 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 Total Return Index. 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 Excess Return 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 only 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.

21

Net asset value per share is the net asset value of the Fund divided by the number of outstanding shares.

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 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. Financial Accounting Standards Board (FASB) Accounting Standards Codification for 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.

22

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 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

The Fund’s entire 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 for a particular commodity 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 the Commodity Broker and/or exchange clearinghouses) to perform under the terms of the contracts (credit risk).

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 3 business days after 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. Instead, individual Shareholders may only redeem Shares in integral multiples of 200,000 and only through an Authorized Participant.

Unless otherwise agreed to by the Managing Owner and the Authorized Participant as provided in the next sentence, 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 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 3 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 the non-refundable transaction fee due for the redemption order.

Redemption orders may be placed either (i) through the Continuous Net Settlement (“CNS”) clearing processes of the National Securities Clearing Corporation (the “ NSCC”) or (ii) if outside the CNS Clearing Process, only through the facilities of The Depository Trust Company (“DTC” or the “Depository”) (the “DTC Process”), or a successor depository, and only in exchange for cash. 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 and such fee is not borne by the Fund.

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 (used for) operating activities was $23.8 million and $(729.0) million for the Three Months Ended March 31, 2014 and 2013, 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.

23

During the Three Months Ended March 31, 2014, $5,615.3 million was paid to purchase United States Treasury Obligations and $5,617.0 million was received from sales and maturing contracts. During the Three Months Ended March 31, 2013, $6,692.7 million was paid to purchase United States Treasury Obligations and $5,964.8 million was received from sales and maturing contracts. Unrealized appreciation on United States Treasury Obligations and futures collectively increased by $79.2 million and decreased by $103.4 million during the Three Months Ended March 31, 2014 and 2013, respectively.

Financing Activities

The Fund’s net cash flow provided by (used for) financing activities was $(121.7) million and $286.8 million during the Three Months Ended March 31, 2014 and 2013, respectively. This included $207.8 million and $429.1 million from the sale of Shares to Authorized Participants during the Three Months Ended March 31, 2014 and 2013, respectively.

Results of Operations

FOR THE THREE MONTHS ENDED MARCH 31, 2014 AND 2013

The Fund was launched on January 31, 2006 at $25.00 per Share. The Shares traded on the NYSE Alternext from February 3, 2006 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 Diversified Commodity Index Excess Return™ (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 “DBC”), (ii) the Fund’s NAV (as reflected by the graph “DBCNAV”), and (iii) the closing levels of the Index (as reflected by the graph “DBLCIX”). 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 Commodities. 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 Commodities, which may compel the Fund to trade futures or other instruments that are not Index Commodities as proxies for the Index Commodities. 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 Index Commodities as proxies for the Index Commodities 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.

Additional Legends

The Fund seeks to track changes, whether positive or negative, in the level of the DBIQ Optimum Yield Diversified Commodity Index Excess Return^TM (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 certain commodities. The commodities comprising the Index are Light Sweet Crude Oil, Heating Oil, Aluminum, Gold, Corn, Wheat, Brent Crude, Copper Grade A, Natural Gas, RBOB Gasoline, Silver, Soybeans, Sugar and Zinc (the “Index Commodities”).

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 JANUARY 2007 (RENAMED 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 SEPTEMBER 1997 THROUGH DECEMBER 2006, THE INDEX CLOSING LEVELS REFLECT THE APPLICATION OF THE INDEX METHODOLOGY, AND SELECTION OF INDEX COMMODITIES, 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, 2013, 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.

THE MANAGING OWNER, AN INDIRECT WHOLLY OWNED SUBSIDIARY OF DEUTSCHE BANK AG, COMMENCED OPERATIONS IN JANUARY 2006. AS MANAGING OWNER, THE MANAGING OWNER AND ITS TRADING PRINCIPALS HAVE BEEN MANAGING THE DAY-TO-DAY OPERATIONS FOR THE FUND AND RELATED PRODUCTS AND MANAGING FUTURES ACCOUNTS. BECAUSE THERE ARE LIMITED ACTUAL TRADING RESULTS TO COMPARE TO THE INDEX CLOSING LEVELS SET FORTH HEREIN, PROSPECTIVE INVESTORS SHOULD BE PARTICULARLY WARY OF PLACING UNDUE RELIANCE ON THE ANNUAL OR CUMULATIVE INDEX RESULTS.

FOR THE THREE MONTHS ENDED MARCH 31, 2014 COMPARED TO THE THREE MONTHS ENDED MARCH 31, 2013

Fund Share Net Asset Performance

For the Three Months Ended March 31, 2014, the net asset value of each Share increased 2.03% from $25.61 per Share to $26.13 per Share. Rising futures contracts prices for brent crude oil, corn, gold, wheat, soybean, natural gas, sugar and silver were partially offset by lower futures contract prices for heating oil, aluminum, zinc, copper grade A, RBOB gasoline, and light crude oil during the Three Months Ended March 31, 2014 contributing to an overall 2.16% increase in the level of the DBIQ-OY Diversified TR™.

Net income for the Three Months Ended March 31, 2014 was $106.0 million, resulting from $0.7 million of interest income, net realized gain of $38.0 million, net change in unrealized gain of $79.2 million and operating expenses of $11.9 million.

For the Three Months Ended March 31, 2013, the net asset value of each Share decreased 1.41% from $27.72 per Share to $27.33 per Share. Declining futures contracts prices for corn, gold, aluminum, wheat, zinc, copper grade A, soybean, sugar and silver were partially offset by higher future contract prices for Brent crude oil, heating oil, RBOB gasoline, natural gas and light crude oil during the Three Months Ended March 31, 2013 contributing to an overall 1.16% decrease in the level of the DBIQ-OY Diversified TR™.

Net loss for the Three Months Ended March 31, 2013 was $101.1 million, resulting from $1.3 million of interest income, net realized gain of $15.7 million, net change in unrealized loss of $103.4 million and operating expenses of $14.7 million.

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 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.

Value at Risk, or VaR, is a measure of the maximum amount which the Fund could reasonably be expected to lose in a given market sector. 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.

27

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 March 31, 2014.

Description	Total Assets		Daily Volatility			VaR* (99  Percentile)		Number of times VaR Exceeded
PowerShares DB Commodity Index Tracking Fund	$	6,714,453,979		0.65	%	$	86,270,114		0

The following table indicates the trading VaR associated with the Fund’s total assets as of December 31, 2013.

Description	Total Assets		Daily Volatility			VaR* (99 Percentile)		Number of times VaR Exceeded
PowerShares DB Commodity Index Tracking Fund	$	6,799,938,046		0.65	%	$	86,445,582		3

* 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.

NON-TRADING RISK

The Fund has non-trading market risk as a result of investing in short-term United States Treasury Obligations. As such, 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.

28

The following were the primary trading risk exposures of the Fund as of March 31, 2014 by market sector.

ENERGY

Light Sweet Crude Oil

The price of light sweet crude oil is volatile and is affected by numerous factors. The level of global industrial activity influences the demand for light sweet crude oil. In addition, various other factors can affect the demand for light sweet crude oil, such as weather, political events and labor activity. The supply of light sweet crude oil can be affected by many events, in particular, the meetings of the Organization of Petroleum Exporting Countries. Market expectations about events that will influence either demand or supply can cause prices for light sweet crude oil to fluctuate greatly. A significant amount of the world oil production capacity is controlled by a relatively small number of producers. Any large change in production by one of these producers could have a substantial effect on the price of light sweet crude oil.

Heating Oil

The price of heating oil is volatile and is affected by numerous factors. The level of global industrial activity influences the demand for heating oil. In addition, the seasonal temperatures in countries throughout the world can also heavily influence the demand for heating oil. Heating oil is derived from crude oil and as such, any factors that influence the supply of crude oil may also influence the supply of heating oil.

Brent Crude Oil

The price of Brent crude oil is volatile and is affected by numerous factors. The price of Brent crude oil is influenced by many factors, including, but not limited to, the amount of output by oil producing nations, worldwide supply/stockpiles, weather, various geopolitical factors that cause supply disruptions (e.g., war, terrorism), global demand (particularly from emerging nations), currency fluctuations, and activities of market participants such as hedgers and speculators.

RBOB Gasoline

The price of RBOB Gasoline is volatile and is affected by numerous factors. The level of global industrial activity influences the demand for RBOB Gasoline. In addition, the demand has seasonal variations, which occur during “driving seasons” usually considered the summer months in North America and Europe. RBOB Gasoline is derived from crude oil and as such, any factors that influence the supply of crude oil may also influence the supply of RBOB Gasoline.

Natural Gas

The price of natural gas is volatile and is affected by numerous factors. The level of global industrial activity influences the demand for natural gas. In addition to the seasonal temperatures in countries throughout the world, any fluctuations in temperature may also heavily influence the demand for natural gas.

METALS

Gold

The price of gold is volatile and is affected by numerous factors. Gold prices float freely in accordance with supply and demand. The price movement of gold may be influenced by a variety of factors, including announcements from central banks regarding reserve gold holdings, agreements among central banks, purchases and sales of gold by central banks, other governmental agencies that hold large supplies of gold, political uncertainties, economic concerns such as an increase or decrease in confidence in the global monetary system, the relative strength of the U.S. dollar, interest rates and numerous other factors. Gold prices may also be affected by industry factors such as industrial and jewelry demand.

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 dependent upon the use 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.

Aluminum

The price of aluminum is volatile. The price movement of aluminum may be influenced by a variety of factors, including the level of global industrial activity and demand, especially relating to the transportation, packaging and building sectors, each of which significantly influences the demand, and in turn, the price of aluminum. Prices for aluminum are influenced by a number of factors including the level of economic activity in large aluminum consuming markets, political uncertainties, economic concerns and the rate of supply of new metal from producers. The production of aluminum is a power intensive process that requires large amounts of inexpensive power. Disruptions in the amount of energy available to aluminum producers could affect the supply of aluminum.

29

Zinc

The price of zinc is volatile and is affected by numerous factors. The price of zinc is primarily affected by the global demand for and supply of zinc. Demand for zinc is significantly influenced by the level of global industrial economic activity. The galvanized steel industrial sector is particularly important given that the use of zinc in the manufacture of galvanized steel accounts for approximately 50% of world-wide zinc demand. The galvanized steel sector is in turn heavily dependent on the automobile and construction sectors. An additional, but highly volatile component of demand, is adjustments to inventory in response to changes in economic activity and/or pricing levels. The supply of zinc concentrate (the raw material) has generally been dominated by China, Australia, North America and Latin America. The supply of zinc is also affected by current and previous price levels, which will influence investment decisions in new mines and smelters. It is not possible to predict the aggregate effect of all or any combination of these factors.

Copper

The price of copper is volatile. The price of copper is primarily affected by the global demand for and supply of copper. Demand for copper is significantly influenced by the level of global industrial economic activity. Industrial sectors which are particularly important include the electrical and construction sectors. In recent years demand has been supported by strong consumption from newly industrializing countries, which continue to be in a copper-intensive period of economic growth as they develop their infrastructure (such as China). An additional, but highly volatile, component of demand is adjustments to inventory in response to changes in economic activity and/or pricing levels. Apart from the United States, Canada and Australia, the majority of copper concentrate supply (the raw material) comes from outside the Organization for Economic Cooperation and Development countries. Chile is the largest producer of copper concentrate. In previous years, copper supply has been affected by strikes, financial problems, political turmoil and terrorist activity.

AGRICULTURAL

Corn

The price of corn is volatile. The price movement of corn may be influenced by three primary supply factors: farmer planting decisions, climate, and government agricultural policies and three major market demand factors: livestock feeding, shortages or surpluses of world grain supplies, and domestic and foreign government policies and trade agreements. Additionally, the price movement of corn may be influenced by a variety of other factors, including weather conditions, disease, transportation costs, political uncertainties and economic concerns.

Wheat

The price of wheat is volatile. The price movement of wheat may be influenced by three primary supply factors: farmer planting decisions, climate, and government agricultural policies and three major market demand factors: food, shortages or surpluses of world grain supplies, and domestic and foreign government policies and trade agreements. Additionally, the price movement of wheat may be influenced by a variety of other factors, including weather conditions, disease, transportation costs, political uncertainties and economic concerns.

Soybeans

The price of soybeans is volatile. The price movement of soybeans may be influenced by a variety of factors, including demand, weather conditions, disease, crop production, transportation costs, political uncertainties and economic concerns.

Sugar

The price of sugar is volatile. The price movement of sugar may be influenced by a variety of factors, including demand, weather conditions, disease, crop production, transportation costs, political uncertainties and economic concerns.

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.

30

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 Martin Kremenstein, its Chief Executive Officer, and Michael Gilligan, its Chief 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 Exchange Act) as of the end of the period covered by this quarterly report, and, based upon that evaluation, Martin Kremenstein, the Chief Executive Officer, and Michael Gilligan, the Chief 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 Chief 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 quarter ended March 31, 2014 that has materially affected, or is reasonably likely to materially affect, the Fund’s internal control over financial reporting.

Disclosures Under Iran Threat Reduction and Syria Human Rights Act of 2012 (“ITRA”)

Deutsche Bank AG, an affiliate of ours, has provided us the disclosure set forth below describing the ITRA-relevant activities of it and its affiliates for the quarter ended March 31, 2014. All references in this quoted disclosure to “we,” “us” and “our” are to Deutsche Bank AG and its affiliates. None of the disclosed activities or transactions were conducted by the Registrant.

Disclosures Under Iran Threat Reduction and Syria Human Rights Act of 2012

Under Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012, which added Section 13(r) of the U.S. Securities Exchange Act of 1934, as amended, an issuer of securities registered under the Securities Exchange Act of 1934 is required to disclose in its periodic reports filed under the Securities Exchange Act of 1934 certain of its activities and those of its affiliates relating to Iran and to other persons sanctioned by the U.S. under programs relating to terrorism and proliferation of weapons of mass destruction that occurred during the period covered by the report. We describe below a number of potentially disclosable activities of Deutsche Bank AG and its affiliates. Disclosure is generally required regardless of whether the activities, transactions or dealings were conducted in compliance with applicable law.

Legacy Financing Arrangements. Despite having ceased entering into new business in or with Iran in 2007, we continue to be engaged as lender, sponsoring bank and/or facility agent or arranger in several long-term financing agreements relating to the construction or acquisition of plant or equipment for the petroleum and petrochemical industries, under which Iranian entities were the direct or indirect borrowers. Before 2007, as part of banking consortia, we entered into a number of financing arrangements, six of which remained outstanding as of March 31, 2014, with the National Iranian Oil Company (NIOC), the National Petrochemical Company (NPC), Bank Melli Iran and their respective group entities as borrowers. The latest final maturity under these loan facilities is in 2019. These loan facilities were guaranteed by national export credit agencies representing two European governments and one Asian national government. In principle, the obligations of the borrowers under these loan facilities are secured by assignments of receivables

32

from oil and oil products exported by NIOC, NPC and/or their trading subsidiaries to buyers, mostly in Asia. These delivery obligations, however, were waived for the period covered by this report, due to the current sanctions environment. For some of these arrangements, we act as escrow agent, holding escrow accounts for the Iranian borrowers mentioned above, into which receivables are, in principle, paid by the buyers of the oil and oil products. During the period covered by this report, no such receivables were paid to the said escrow accounts. Such accounts are pledged in favor of the relevant banking consortium. We have no involvement in the contractual arrangements related to, or in the physical settlement of, the oil and oil product exports mentioned above. The Iranian entities in whose names the escrow accounts are held are not permitted to draw on these accounts, either because they are sanctioned parties or, where this is not the case, due to our business decision to not allow access to the accounts in light of the overall sanctions environment.

During the first quarter of 2014, approximately € 1.0 million was paid into the escrow account. We, in our role as agent, distributed to the participants in the banking consortia € 1.0 million including portions attributable to us totaling approximately € 0.25 million.

We generated revenues in the first quarter of 2014 of approximately € 0.7 million in respect of these financing arrangements, of which approximately € 0.6 million consisted of escrow account revenues, € 40,000 consisted of loan interest revenues and € 10,000 consisted of fee revenues. The net profits were less than these amounts.

As of March 31, 2014, we have an undrawn commitment of approximately € 1.3 million under one of the financing agreements referred to above. Due to the export credit agency coverage, this remainder cannot be cancelled without German government approval, for which we have applied but have not yet received. We do not intend to make further disbursements upon this undrawn commitment.

A wholly owned subsidiary of ours, BHF-BANK AG, which we acquired as part of the acquisition of the Sal. Oppenheim Group in March 2010 and which we have sold effective March 26, 2014, was a lender participant in a number of similar arrangements, the borrowers of which were Bank Saderat, Bank Melli, Bank Tejarat and NPC. In that capacity, it received approximately € 200 fees in the first quarter of 2014, which was paid by us to BHF-BANK in our capacity as agent or arranger. Of the amounts received, BHF-BANK passed on approximately € 100 to participants in such arrangements. In the first quarter of 2014, BHF-BANK’s gross revenues from this business were approximately € 14,000 and its net profits were less than this amount.

Our portion of the remaining loan facilities (not including the part held by BHF-BANK at the time of its sale) amounted to approximately € 33 million as of March 31, 2014. We intend to continue pursuing repayment and fulfilling our administrative role under these agreements, but we do not intend to engage in any new extensions of credit to these or other Iranian entities.

Legacy Contractual Obligations Related to Guarantees and Letters of Credit. Prior to 2007, we provided guarantees to a number of Iranian entities. In almost all of these cases, we issued counter-indemnities in support of guarantees issued by Iranian banks because the Iranian beneficiaries of the guarantees required that they be backed directly by Iranian banks. In 2007, we made a decision to discontinue issuing new guarantees to Iranian or Iran-related beneficiaries. Although the pre-existing guarantees stipulate that they must be either extended or honored if we receive such a demand and we are legally not able to terminate these guarantees, we decided in 2011 to reject any “extend or pay” demands under such guarantees. Even though we exited, where possible, many of these guarantees, guarantees with an aggregate face amount of approximately € 7.8 million are still outstanding as of March 31, 2014. The gross revenues from this business were approximately € 11,000 and the net profit we derived from these activities was less than this amount.

We also have outstanding legacy guarantees in relation to a Syrian bank sanctioned by the U.S. under its non-proliferation program. The aggregate face amount of these legacy guarantees was approximately € 9.0 million, the gross revenues received from non-Syrian parties for these guarantees were approximately € 20,000 and the net profit we derived from these activities was less than this amount. In one case we paid cancellation fees of less than € 400 to the frozen account of the Syrian bank.

We intend to exit these guarantee arrangements as soon as possible.

BHF-BANK, based on similar legacy guarantees issued before 2010, paid commissions and charges of approximately € 32,000 to accounts of relevant Iranian banks frozen under applicable EU law. BHF-BANK received approximately € 35,000 in fees from the non-Iranian parties for which the guarantees were issued and their net profits were less than this amount. The aggregate face amount of these legacy guarantees was approximately € 19 million at the time of the BHF-BANK sale.

BHF-BANK also has outstanding legacy guarantees in relation to a Syrian bank sanctioned by the U.S. under its non-proliferation program. The aggregate face amount of these legacy guarantees was less than € 0.4 million, the gross revenues received from non-Syrian parties for these guarantees were less than € 1,500 and the net profit derived from these activities was less than this amount.

Payments Received. We received less than 15 payments adding up to approximately € 3 million in favor of non-Iranian clients in Germany and the Netherlands, which payments stemmed ultimately from relevant Iranian entities. Revenues for these incoming payments were less than € 3,000. These figures include relevant payments in favor of clients of our subsidiary Postbank. We expect that we will also have to execute such transactions in the future.

33

Operations of Iranian Bank Branches and Subsidiaries in Germany and/or France. Several Iranian banks, including Bank Melli Iran, Bank Saderat, Bank Tejarat and Europäisch-Iranische Handelsbank, have branches or offices in Germany and/or France, even though their funds and other economic resources are frozen under European law. As part of the payment clearing system in Germany and other European countries, when these branches or offices need to make payments in Germany or Europe to cover their day-to-day operations such as rent, taxes, insurance premia and salaries for their remaining staff, or for any other kind of banking-related operations necessary to wind down their legacy trade business, the German Bundesbank and French banks accept fund transfers from these Iranian banks and disburse them to the applicable (mainly German) payees, some of whom hold accounts with us. In the first quarter of 2014, we received approximately € 1 million in such disbursements in approximately 200 transactions via the German Bundesbank and French banks in respect of payments from the above-mentioned Iranian banks, and the gross revenues derived from these payments were less than € 1,000. Relevant transactions of our subsidiary Postbank are included in these figures. We expect that we will also have to execute such transactions in the future.

Based on discussions initiated by the German Bundesbank, BHF-BANK continues to maintain accounts for Bank Sepah’s branch in Frankfurt, Germany. These accounts are frozen under European sanctions law. In the first quarter of 2014, the total volume of outgoing payments from these accounts was approximately € 0.5 million, which payments were made with the involvement of the competent authorities in Germany under applicable law. In the first quarter of 2014, the gross revenues from this activity were approximately € 4,000 and the net profits were less than this amount.

Maintaining of Accounts for Iranian Consulates and Embassies. In the first quarter of 2014, Iranian embassies and consulates in Germany and the Netherlands were holding accounts with us as well as with Postbank. This includes the provision by a subsidiary of Postbank to the Iranian consulate of girocard (debitcard/ATM)-terminals as well as the processing of transactions of cardholders using the terminals; the terminals are used to facilitate the payment of fees for the issuance of visas and other administrative measures by the consulate. The additional purpose of these accounts was the funding of day-to-day operational costs of the embassies and consulates, such as salaries, rent, and electricity. One of the account relationships was between Deutsche Bank Netherlands N.V. and the Agent Bureau of the Embassy of the Islamic Republic of Iran in The Hague (which is responsible for all Iran-U.S. Claims Tribunal activities). The total volume of outgoing payments from these accounts was approximately € 9 million in the first quarter of 2014, which payments were made with the involvement of the competent authorities in the relevant European countries under applicable law. We derived gross revenues of approximately € 12,000 and net profits which were less than this amount from these activities. The relevant European governments have requested that we continue to provide these services in the future to enable the Government of Iran to conduct its diplomatic relations.

Relationships with Corporate Clients. We maintain a business relationship with one corporate client registered in Germany who was sanctioned by the US in the first quarter of 2014 pursuant to Executive Order 13382. We did not terminate this relationship but imposed several restrictive measures to mitigate the relevant risks. The revenues derived from this relationship were less than € 1,000 and the net profits were less than this amount.

Activities of Entities in Which We Have Interests. Section 13(r) requires us to provide the specified disclosure with respect to ourselves and our “affiliates,” as defined in Exchange Act Rule 12b-2. Although we have minority equity interests in certain entities that could arguably result in these entities being deemed “affiliates,” we do not have the authority or the legal ability to acquire in every instance the information from these entities that would be necessary to determine whether they are engaged in any disclosable activities under Section 13(r). In some cases, legally independent entities are not permitted to disclose the details of their activities to us because of German privacy and data protection laws or the applicable banking laws and regulations. In such cases, voluntary disclosure of such details could violate such legal and/or regulatory requirements and subject the relevant entities to criminal prosecution or regulatory investigations.

Fund Investment Overview

(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 Diversified Commodity Index Excess Return™ (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 commodity sector. The commodities comprising the Index are Light Sweet Crude Oil, Heating Oil, Aluminum, Gold, Corn, Wheat, Brent Crude, Copper Grade A, Natural Gas, RBOB Gasoline, Silver, Soybeans, Sugar and Zinc (the “Index Commodities”).

The Commodity Futures Trading Commission (the “CFTC”) and/or commodity exchanges, as applicable, impose position limits on market participants trading in certain commodities futures contracts included in the Index. The Index is comprised of futures contracts on each of the Index Commodities 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 any Index Commodity by investing in a specific Index Contract, the Fund may invest in a futures contract referencing the particular Index Commodity other than the Index Contract or, in the alternative, invest in other futures contracts not based on the particular Index Commodity if, in the commercially reasonable judgment of the Managing Owner, such futures contracts tend to exhibit trading prices that correlate with such Index Commodity. Because the Fund is approaching or has reached position limits with respect to certain futures contracts comprising the Index, the Fund has commenced investing in other futures contracts based on commodities that comprise the Fund’s Index and in futures contracts based on commodities other than commodities that comprise the Fund’s Index.

The Fund has been subject to accountability levels with respect to both light sweet crude oil (WTI) and RBOB Gasoline, each of which are index futures contracts that are listed on the NYMEX. As a result of reaching the accountability levels with respect to light sweet crude oil (WTI), the Fund invested in the ICE West Texas Intermediate Light Sweet Crude Oil futures contracts with comparable expirations during the period from January 2, 2013 to June 3, 2013. As a result of reaching the accountability levels with respect to RBOB Gasoline, the Fund invested in the next sequential expiring RBOB Gasoline futures contract also listed on the NYMEX during the period from January 2, 2013 and continued to maintain its positions in such contracts as of September 30, 2013.

During the period from December 12, 2012 to June 10, 2013, the Managing Owner was ordered by the Market Regulation Department of the NYMEX to no longer increase, on either an intraday or end of day basis, the Fund’s net positions in RBOB Gasoline futures contracts. Such order was retracted effective June 10, 2013.

During the period from November 30, 2012 to January 25, 2013, the Managing Owner was ordered by the Market Regulation Department of the NYMEX to no longer increase, on either an intraday or end of day basis, the Fund’s net positions in light sweet crude oil (WTI) futures contracts. Such order was retracted effective January 25, 2013.

The Fund also holds United States Treasury Obligations for deposit with the Fund’s commodity broker as margin. The Fund does not borrow money to increase leverage. As of March 31, 2014 and December 31, 2013, the Fund had $6,688,454,774 (or 99.6%) and $6,799,938,046 (or 100.0%), respectively, of its holdings of cash, United States Treasury Obligations and unrealized appreciation/depreciation of futures contracts on deposit with its Commodity Broker. Of this, $287,490,157 (or 4.3%) and $347,808,276 (or 5.12%), respectively, of the Fund’s holdings of cash and United States Treasury Obligations are required to be deposited as margin in support of the Fund’s long futures positions as of March 31, 2014 and December 31, 2013, respectively. For additional information, please see the unaudited Schedule of Investments as of March 31, 2014 and the audited Schedule of Investments as of December 31, 2013 for details of the Fund’s portfolio holdings.

Financial Instrument Risk

3 Months Ended

Mar. 31, 2014

Investments Debt And Equity Securities [Abstract]

Financial Instrument Risk

(5) 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 in excess of the amounts shown in the Statement of Financial Condition. The financial instruments used by the Fund are exchange-listed 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 the Commodity Broker and/or 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 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 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. 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.

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.

Summary of Significant Accounting Policies

3 Months Ended

Mar. 31, 2014

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

(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.

In June 2013, the FASB issued updated guidance clarifying the characteristics of an investment company and requiring new disclosures. Under the guidance, all entities regulated under the Investment Company Act of 1940 automatically qualify as investment companies, while all other entities need to consider both the fundamental and typical characteristics of an investment company in determining whether they qualify as investment companies. This new guidance is effective for interim or annual reporting periods that begin after December 15, 2013, and should be applied prospectively. The Fund adopted this guidance effective January 1, 2014. The Fund has determined that it meets the definition of an investment company and has prepared the unaudited financial statements in conformity with generally accepted accounting principles in the United States of America for investment companies. The adoption of this guidance had no effect on the Fund’s unaudited statements of financial condition, including the schedule of investments, and the related unaudited statements of income and expenses, changes in shareholders’ equity and of cash flows.

(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. There were no significant estimates used in the preparation of these financial statements. The brokerage agreement with the Commodity Broker provides for the net settlement of all financial instruments covered by the agreement in the event of default or termination of any one contract.

(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). The brokerage agreement with the Commodity Broker provides for the net settlement of all financial instruments covered by the agreement in the event of default or termination of any one contract.

Financial Accounting Standards Board (FASB) Accounting Standards Codification 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.

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 non-LME commodity futures contracts, the Fund uses unadjusted quoted market prices in active markets. United States Treasury Obligations and non-LME 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.

In determining fair value of LME commodity futures contracts, the Fund uses valuation pricing based on action of a committee that incorporates prices from the most liquid trading sessions of the day and can also rely on other inputs such as trades, bids and offers (including indicative bids and offers) transacted throughout the whole day. During the year ended December 31, 2013, management changed the classification of LME commodity futures from Level 1 to Level 2.

Assets and Liabilities Measured at Fair Value as of March 31, 2014 were as follows:

	Level 1		Level 2			Total
United States Treasury Obligations	$	6,546,792,463		—		$	6,546,792,463
Commodity Futures Contracts	$	132,380,891	$	(15,925,413	)	$	116,455,478

Assets and Liabilities Measured at Fair Value as of December 31, 2013 were as follows:

	Level 1		Level 2			Total
United States Treasury Obligations	$	6,639,612,594		—		$	6,639,612,594
Commodity Futures Contracts	$	56,755,799	$	(19,503,125	)	$	37,252,674

There were no Level 3 holdings during the quarter ended March 31, 2014 and the year ended December 31, 2013. Futures contracts in a net depreciation position of 19,503,125 were transferred from Level 1 to Level 2 during the year ended December 31, 2013 as described above.

(d) Deposits with Commodity Broker

The Fund deposits cash and United States Treasury Obligations with its Commodity Broker subject to CFTC regulations and various exchange and Commodity 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 Commodity 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 in interest income over the life of the United States Treasury Obligations. The Fund purchased $1,023,000,000 face amount of United States Treasury Obligations which was recorded as a payable as of March 31, 2014. As a result, a payable for securities purchased is reported for $1,022,896,563. The Fund purchased $1,089,000,000 face amount of United States Treasury Obligations which was recorded as a payable as of December 31, 2013. As a result, a payable for securities purchased is reported for $1,088,821,071.

(f) Cash Held by Commodity 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 March 31, 2014 the Fund had $25,206,833 of cash held with the Commodity Broker. As of December 31, 2013 the Fund had cash held by the Commodity Broker of $123,072,778. As of March 31, 2014 and December 31, 2013 there were no cash equivalents held by the Fund.

(g) Receivable/(Payable) for LME Contracts

The Fund trades aluminum, copper and zinc commodity future contracts on the London Metals Exchange (“LME”). For settlement of futures contracts traded on the LME, cash is not transferred until the settled futures contracts expire. As of March 31, 2014, the Fund had a payable to the Commodity Broker for contracts on the LME of $6,663,044 related to net realized losses on LME contracts. As of December 31, 2013, the Fund had a payable to the Commodity Broker of $10,356,375 related to net realized losses on LME contracts which have been closed out but the contract is not yet expired.

(h) 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, 2009.

(i) Futures Contracts

All commodity futures contracts are held and used for trading purposes. Commodity futures contracts 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 contracts 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. For the quarters ended March 31, 2014 and 2013, the average notional market value of futures contracts held was $5.8 billion and $7.0 billion, respectively.

The Fair Value of Derivative Instruments is as follows:

Derivatives not Accounted for as Hedging Instruments	Statements of Financial Condition Location	Net Unrealized Appreciation / (Depreciation) at March 31, 2014		Net Unrealized Appreciation / (Depreciation) at December 31, 2013
Commodity Futures Contracts	Net Unrealized Appreciation (Depreciation) on Futures Contracts	$	116,455,478	$	37,252,674

The Effect of Derivative Instruments on the Statements of Income and Expenses is as follows:

		For the Three Months Ended March 31, 2014				For the Three Months Ended March 31, 2013

(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

Equity [Abstract]

Share Purchases and Redemptions

(6) Share Purchases and Redemptions

(a) Purchases

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 3 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 the non-refundable transaction fee due for the creation order.

Unless otherwise agreed to by the Managing Owner and the Authorized Participant as provided in the next sentence, 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 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 3 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 the non-refundable transaction fee due for the creation order.

Creation orders may be placed either (i) through the Continuous Net Settlement (“CNS”) clearing processes of the National Securities Clearing Corporation (the “NSCC”) or (ii) if outside the CNS Clearing Process, only through the facilities of The Depository Trust Company (“DTC” or the “Depository”) (the “DTC Process”), or a successor depository.

(b) Redemptions

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 3 business days after the redemption order date. The redemption procedures allow Authorized Participants to redeem Baskets. Individual Shareholders may not redeem directly from the Fund. Instead, individual Shareholders may only redeem Shares in integral multiples of 200,000 and only through an Authorized Participant.

Unless otherwise agreed to by the Managing Owner and the Authorized Participant as provided in the next sentence, 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 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 3 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 the non-refundable transaction fee due for the redemption order.

Redemption orders may be placed either (i) through the CNS clearing processes of the NSCC or (ii) if outside the CNS Clearing Process, only through the DTC Process, or a successor depository, and only in exchange for cash. 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 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.

The redemption proceeds due from the 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.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2014

Accounting Policies [Abstract]

Basis of Presentation

(a) Basis of Presentation

The financial statements of the Fund have been prepared using U.S. generally accepted accounting principles.

In June 2013, the FASB issued updated guidance clarifying the characteristics of an investment company and requiring new disclosures. Under the guidance, all entities regulated under the Investment Company Act of 1940 automatically qualify as investment companies, while all other entities need to consider both the fundamental and typical characteristics of an investment company in determining whether they qualify as investment companies. This new guidance is effective for interim or annual reporting periods that begin after December 15, 2013, and should be applied prospectively. The Fund adopted this guidance effective January 1, 2014. The Fund has determined that it meets the definition of an investment company and has prepared the unaudited financial statements in conformity with generally accepted accounting principles in the United States of America for investment companies. The adoption of this guidance had no effect on the Fund’s unaudited statements of financial condition, including the schedule of investments, and the related unaudited statements of income and expenses, changes in shareholders’ equity and of cash flows.

Use of Estimates

(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. There were no significant estimates used in the preparation of these financial statements. The brokerage agreement with the Commodity Broker provides for the net settlement of all financial instruments covered by the agreement in the event of default or termination of any one contract.

Financial Instruments and Fair Value

(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). The brokerage agreement with the Commodity Broker provides for the net settlement of all financial instruments covered by the agreement in the event of default or termination of any one contract.

Financial Accounting Standards Board (FASB) Accounting Standards Codification 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.

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 non-LME commodity futures contracts, the Fund uses unadjusted quoted market prices in active markets. United States Treasury Obligations and non-LME 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.

In determining fair value of LME commodity futures contracts, the Fund uses valuation pricing based on action of a committee that incorporates prices from the most liquid trading sessions of the day and can also rely on other inputs such as trades, bids and offers (including indicative bids and offers) transacted throughout the whole day. During the year ended December 31, 2013, management changed the classification of LME commodity futures from Level 1 to Level 2.

Assets and Liabilities Measured at Fair Value as of March 31, 2014 were as follows:

	Level 1		Level 2			Total
United States Treasury Obligations	$	6,546,792,463		—		$	6,546,792,463
Commodity Futures Contracts	$	132,380,891	$	(15,925,413	)	$	116,455,478

Assets and Liabilities Measured at Fair Value as of December 31, 2013 were as follows:

	Level 1		Level 2			Total
United States Treasury Obligations	$	6,639,612,594		—		$	6,639,612,594
Commodity Futures Contracts	$	56,755,799	$	(19,503,125	)	$	37,252,674

There were no Level 3 holdings during the quarter ended March 31, 2014 and the year ended December 31, 2013. Futures contracts in a net depreciation position of 19,503,125 were transferred from Level 1 to Level 2 during the year ended December 31, 2013 as described above.

Deposits with Commodity Broker

(d) Deposits with Commodity Broker

The Fund deposits cash and United States Treasury Obligations with its Commodity Broker subject to CFTC regulations and various exchange and Commodity 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 Commodity 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.

United States Treasury Obligations

(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 in interest income over the life of the United States Treasury Obligations. The Fund purchased $1,023,000,000 face amount of United States Treasury Obligations which was recorded as a payable as of March 31, 2014. As a result, a payable for securities purchased is reported for $1,022,896,563. The Fund purchased $1,089,000,000 face amount of United States Treasury Obligations which was recorded as a payable as of December 31, 2013. As a result, a payable for securities purchased is reported for $1,088,821,071.

Cash Held by Commodity Broker

(f) Cash Held by Commodity 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 March 31, 2014 the Fund had $25,206,833 of cash held with the Commodity Broker. As of December 31, 2013 the Fund had cash held by the Commodity Broker of $123,072,778. As of March 31, 2014 and December 31, 2013 there were no cash equivalents held by the Fund.

Receivable/(Payable) for LME Contracts

(g) Receivable/(Payable) for LME Contracts

The Fund trades aluminum, copper and zinc commodity future contracts on the London Metals Exchange (“LME”). For settlement of futures contracts traded on the LME, cash is not transferred until the settled futures contracts expire. As of March 31, 2014, the Fund had a payable to the Commodity Broker for contracts on the LME of $6,663,044 related to net realized losses on LME contracts. As of December 31, 2013, the Fund had a payable to the Commodity Broker of $10,356,375 related to net realized losses on LME contracts which have been closed out but the contract is not yet expired.

Income Taxes

(h) 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, 2009.

Futures Contracts

(i) Futures Contracts

All commodity futures contracts are held and used for trading purposes. Commodity futures contracts 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 contracts 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. For the quarters ended March 31, 2014 and 2013, the average notional market value of futures contracts held was $5.8 billion and $7.0 billion, respectively.

The Fair Value of Derivative Instruments is as follows:

Derivatives not Accounted for as Hedging Instruments	Statements of Financial Condition Location	Net Unrealized Appreciation / (Depreciation) at March 31, 2014		Net Unrealized Appreciation / (Depreciation) at December 31, 2013
Commodity Futures Contracts	Net Unrealized Appreciation (Depreciation) on Futures Contracts	$	116,455,478	$	37,252,674

The Effect of Derivative Instruments on the Statements of Income and Expenses is as follows:

		For the Three Months Ended March 31, 2014				For the Three Months Ended March 31, 2013
Derivatives not Accounted for as Hedging Instruments	Location of Gain or (Loss) on Derivatives Recognized in Income	Realized Gain or (Loss) on Derivatives Recognized in Income		Change in Unrealized Gain or (Loss) on Derivatives Recognized in Income		Realized Gain or (Loss) on Derivatives Recognized in Income		Change in Unrealized Gain or (Loss) on Derivatives Recognized in Income
Commodity Futures Contracts	Net Realized Gain (Loss) on Futures	$	37,969,343		—	$	15,731,107		—
	Net Change in Unrealized Gain (Loss) on Futures		—	$	79,202,804		—	$	(103,327,228	)

The Fund utilizes derivative instruments to achieve each Fund’s investment objective. For financial reporting purposes, the Fund offsets financial assets and financial liabilities that are subject to master netting arrangements or similar agreements in the statement of financial condition. The following table presents the gross and net amounts of these assets and liabilities with any offsets to reflect the Funds’ ability to reflect the master netting agreements at March 31, 2014:

								Gross Amounts Not Offset in the Statement of Financial Condition
Assets	Gross Amount of Recognized Assets		Gross Amounts Offset in the Statement of Financial Condition			Net Amounts of Assets Presented in the Statement of Financial Condition		Financial Instruments		Cash Collateral Pledged		Net Amount
Commodity Futures Contracts	$	184,076,678	$	(67,621,200	)	$	116,455,478	$	—	$	—	$	116,455,478
