(1) Background

On October 24, 2014, DB Commodity Services LLC, a Delaware limited liability company (“DBCS”), DB U.S. Financial Markets Holding Corporation (“DBUSH”) and Invesco PowerShares Capital Management LLC (“Invesco”) entered into an Asset Purchase Agreement (the “Agreement”). DBCS is a wholly-owned subsidiary of DBUSH. DBCS agreed to transfer and sell to Invesco all of DBCS’ interest in PowerShares DB Oil Fund (the “Fund”), a separate series of PowerShares DB Multi-Sector Commodity Trust (the “Trust”), a Delaware statutory trust organized in seven separate series, including the sole and exclusive power to direct the business and affairs of the Trust and the Fund, as well as certain other assets pertaining to the management of the Trust and the Fund, pursuant to the terms and conditions of the Agreement (the “Transaction”).

The Transaction was consummated on February 23, 2015 (the “Closing Date”). Invesco now serves as the managing owner (the “Managing Owner”), commodity pool operator and commodity trading advisor of the Trust and the Fund, in replacement of DBCS (the “Predecessor Managing Owner”).

(2) Organization

The Fund is a separate series of the Trust. The Trust is a Delaware statutory trust organized in seven separate series and was formed on August 3, 2006. The Predecessor Managing Owner seeded the Fund with a capital contribution of $1,000 in exchange for 40 General Shares of the Fund. The General Shares were sold to the Managing Owner by the Predecessor Managing Owner pursuant to the terms of the Agreement. The fiscal year end of the Fund is December 31st. The term of the Fund is perpetual (unless terminated earlier in certain circumstances) as provided for in the Fifth Amended and Restated Declaration of Trust and Trust Agreement of the Trust (the “Trust Agreement”). The Fourth Amended and Restated Declaration of Trust and Trust Agreement of the Trust dated November 12, 2012 was effective for purposes of the reporting period up to and excluding the Closing Date. The Fund has an unlimited number of shares authorized for issuance.

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

This Report covers the three months ended March 31, 2015 and 2014 (hereinafter referred to as the “Three Months Ended March 31, 2015” and the “Three Months Ended March 31, 2014”, respectively). The Fund’s performance information from inception up to and excluding the Closing Date is a reflection of the performance associated with the Predecessor Managing Owner. The Managing Owner has served as managing owner of the Fund since the Closing Date, and the Fund’s performance information since the Closing Date is a reflection of the performance associated with the Managing Owner. Past performance of the Fund is not necessarily indicative of future performance.

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, 2014 as filed with the SEC on March 6, 2015.

(3) 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 Crude Oil Index Excess Return™ (the “DBIQ-OY CL ER™”, or the “Index”) over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. The Index is intended to reflect the change in market value of the crude oil sector. The single commodity comprising the Index is Light Sweet Crude Oil (WTI) (the “Index Commodity”).

The Commodity Futures Trading Commission (the “CFTC”) and/or commodity exchanges, as applicable, impose position limits on market participants trading in the commodity included in the Index. The Index is comprised of futures contracts on the Index Commodity that expire in a specific month and trade on a specific exchange (the “Index Contracts”). As disclosed in the Fund’s

Prospectus, if the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to the Index Commodity by investing in the Index Contract, the Fund may invest in (i) a futures contract referencing the Index Commodity other than the Index Contract or, in the alternative, invest in (ii) other futures contracts not based on the Index Commodity ((i) and (ii) collectively, the “Alternative Futures Contracts”) if, in the commercially reasonable judgment of the Managing Owner, such Alternative Futures Contracts tend to exhibit trading prices that correlate with the Index Commodity.

The Fund 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 and for investment.

The Fund does not borrow money to increase leverage. As of March 31, 2015 and December 31, 2014, the Fund had $76,116,420 (or 8.57% of its total assets) and $290,416,811 (or 100% of its total assets), respectively, of its holdings of cash, United States Treasury Obligations and unrealized appreciation/depreciation on futures contracts on deposit with its Commodity Broker (as defined below) or its Predecessor Commodity Broker (as defined below), as applicable. Of this, $76,116,420 (or 8.57%) and $27,583,325 (or 9.50%) is required to be deposited to satisfy maintenance margin required by the Commodity Broker for the Fund’s open futures positions as of March 31, 2015 and December 31, 2014, respectively. For additional information, please see the unaudited Schedule of Investments as of March 31, 2015 and December 31, 2014 for details of the Fund’s portfolio holdings.

(4) Service Providers and Related Party Agreements

The Trustee

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

The Managing Owner

The Managing Owner serves as the Fund’s commodity pool operator, commodity trading advisor and managing owner. The Fund pays the Managing Owner a management fee, monthly in arrears, in an amount equal to 0.75% per annum of the daily net asset value of the Fund. For purposes of the reporting period up to and excluding the Closing Date, all Management Fees were payable to the Predecessor Managing Owner (the “Management Fee”). The Managing Owner has served as managing owner of the Fund since the Closing Date and all Management Fee accruals since the Closing Date have been paid to the Managing Owner.

During the Three Months Ended March 31, 2015 and 2014, the Fund incurred Management Fees of $773,393 and $561,230, respectively. As of March 31, 2015 and December 31, 2014, Management Fees payable were $333,150 and $167,000, respectively.

The Commodity Broker

Effective as of the Closing Date, Morgan Stanley & Co. LLC, a Delaware limited liability company, serves as the Fund’s futures clearing broker (the “Commodity Broker”). Deutsche Bank Securities Inc. (“DBSI”), a Delaware corporation, served as the Fund’s futures clearing broker up to and excluding the Closing Date (the “Predecessor Commodity Broker”). DBSI is also an indirect wholly-owned subsidiary of Deutsche Bank AG and is an affiliate of the Predecessor Managing Owner. A variety of executing brokers execute futures transactions on behalf of the Fund. Such executing brokers give-up all such transactions to the Commodity Broker. In its capacity as clearing broker, the Commodity Broker may execute or receive transactions executed by others and clears all of the Fund’s futures transactions and performs certain administrative and custodial services for the Fund. The Commodity Broker is responsible, among other things, for providing periodic accountings of all dealings and actions taken by the Trust on behalf of the Fund during the reporting period, together with an accounting of all securities, cash or other indebtedness or obligations held by it or its nominees for or on behalf of the Fund. During the Three Months Ended March 31, 2015 and 2014, the Fund incurred brokerage fees of $149,520 and $5,932, respectively. As of March 31, 2015 and December 31, 2014, brokerage fees payable were $4,835 and $4,666, respectively. For the avoidance of doubt, for purposes of the reporting period up to and excluding the Closing Date, commission payments were paid to the Predecessor Commodity Broker. The Commodity Broker has served as the Fund’s futures clearing broker since the Closing Date and all commission accruals since the Closing Date have been paid to the Commodity Broker.

The Administrator, Custodian and Transfer Agent

The Bank of New York Mellon (the “Administrator” and “Custodian”) is the administrator, custodian and transfer agent of the Fund, and has entered into separate administrative, custodian, transfer agency and service agreements (collectively referred to as the “Administration Agreement”).

Pursuant to the Administration Agreement, the Administrator performs or supervises the performance of services necessary for the operation and administration of the Fund (other than making investment decisions), including receiving and processing orders from Authorized Participants to create and redeem Baskets, net asset value calculations, accounting and other fund administrative services. The Administrator retains certain financial books and records, including: Basket creation and redemption books and records, fund accounting records, ledgers with respect to assets, liabilities, capital, income and expenses, the registrar, transfer journals and related details, and trading and related documents received from the Commodity Broker and other unaffiliated futures commission merchants.

As of December 31, 2014, the Fund held $68,613,950 of cash and $280,990,311 of United States Treasury Obligations at the Predecessor Commodity Broker. In conjunction with the Transaction, during the three-day period from February 24, 2015 to February 26, 2015, the Fund transferred $21,627,202 of cash and $470,990,982 of United States Treasury Obligations from the Predecessor Commodity Broker to the Custodian. Additionally, during that same three-day period, the Fund transferred all of its open positions of commodity futures contracts from the Predecessor Commodity Broker to the Commodity Broker and accordingly, $3,341,590 of futures variation margin was credited to the Commodity Broker account. $67,993,200 of United States Treasury Obligations was also transferred from the Custodian to the Commodity Broker to satisfy maintenance margin requirements. Effective February 26, 2015, the Managing Owner began transferring cash daily from the Custodian to the Commodity Broker to satisfy the previous day’s variation margin on open futures contracts. The cumulative amount of cash transferred to the Commodity Broker as of March 31, 2015 approximates the net unrealized appreciation (depreciation) on commodity futures contracts. As a result, only the current day’s variation margin is disclosed on the Statement of Financial Condition.

As of March 31, 2015, the Fund had $803,899,405 (or 90.46% of total assets) of its holdings of cash and United States Treasury Obligations held with its Custodian. No assets were held at the Custodian on December 31, 2014.

The Managing Owner pays the Administrator administrative services fees out of the Management Fee.

The Distributor

ALPS Distributors, Inc. (the “Distributor”) provides certain distribution services to the Fund. Pursuant to the Distribution Services Agreement among the Managing Owner in its capacity as managing owner of the Fund and the Distributor, the Distributor assists the Managing Owner and the Administrator with certain functions and duties relating to distribution and marketing services to the Fund including reviewing and approving marketing materials.

The Managing Owner pays the Distributor a distribution fee out of the Management Fee.

Index Sponsor

Effective as of the Closing Date, the Managing Owner, on behalf of the Fund, has appointed Deutsche Bank Securities Inc. to serve as the index sponsor (the “Index Sponsor”). Prior to the Closing Date, the index sponsor was Deutsche Bank AG London. The Index Sponsor calculates and publishes the daily index levels and the indicative intraday index levels. Additionally, the Index Sponsor also calculates the indicative value per Share of the Fund throughout each Business Day.

The Managing Owner pays the Index Sponsor a licensing fee and an index services fee out of the Management Fee for performing its duties.

Marketing Agent

Effective as of the Closing Date, the Managing Owner, on behalf of the Fund, has appointed Deutsche Bank Securities Inc. as the marketing agent (the “Marketing Agent”) to assist the Managing Owner by providing support to educate institutional investors about the Deutsche Bank indices and to complete governmental or institutional due diligence questionnaires or requests for proposals related to the Deutsche Bank indices.

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

The Marketing Agent will not open or maintain customer accounts or handle orders for the Fund. The Marketing Agent has no responsibility for the performance of the Fund or the decisions made or actions taken by the Managing Owner.

(5) Summary of Significant Accounting Policies

(a) Basis of Presentation

The Fund has determined that it meets the definition of an investment company and has prepared the unaudited financial statements in conformity with U.S. GAAP for investment companies in conformity with the accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946—Investment Companies.

In August 2014, the FASB issued a new standard, Accounting Standards Update No. 2014-15 Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which will explicitly require management to assess an entity’s ability to continue as a going concern and to provide related footnote disclosure in certain circumstances. This new guidance is effective for all entities in the first annual reporting period ending after December 15, 2016. The Fund is currently evaluating this guidance and its impact on the Fund’s financial statement disclosures.

Notes to Unaudited Financial Statements—(Continued)

March 31, 2015

(b) Use of Estimates

The preparation of the financial statements in conformity with U.S. GAAP 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.

(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. U.S. GAAP defines fair value as 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, under current market conditions.

U.S. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods and market conditions may result in transfers in or out of an investment’s assigned level:

Level 1—Prices are determined using quoted prices in an active market for identical assets.

Level 2—Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.

Level 3—Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

The levels assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

The following is a summary of the tiered valuation input levels as of March 31, 2015:

The Fund’s policy is to recognize transfers in and out of the valuation levels as of the end of the reporting period. Effective on the Closing Date, the Fund revised certain policies with respect to level classification. As a result, United States Treasury Obligations were transferred from Level 1 to Level 2.

The following is a summary of the tiered valuation input levels as of December 31, 2014:

(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 broker requirements. The combination of the Fund’s deposits with its Commodity Broker of cash and United

Notes to Unaudited Financial Statements—(Continued)

March 31, 2015

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

(e) Deposits with Custodian

The combination of the Fund’s deposits with its Custodian of cash and United States Treasury Obligations represents the Fund’s overall assets held with its Custodian.

(f) United States Treasury Obligations

The Fund records purchases and sales of United States Treasury Obligations on a trade date basis. These holdings are marked to market based on quoted market closing prices. The Fund holds United States Treasury Obligations for deposit with the Fund’s Commodity Broker to meet margin requirements and for trading purposes. Interest income is recognized on an accrual basis when earned. Premiums and discounts are amortized or accreted over the life of the United States Treasury Obligations. The Fund purchased $275,000,000 face amount of United States Treasury Obligations valued at $274,980,885 which was recorded as payable for securities purchased as of March 31, 2015. The Fund purchased $11,000,000 face amount of United States Treasury Obligations valued at $10,999,263 which was recorded as payable for securities purchased as of December 31, 2014.

(g) 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 assesses its variation margin requirements on a daily basis and additional cash required to satisfy the variation margin requirement is transferred from the Custodian to the Commodity Broker at the close of business each day. Effective February 24, 2015, only the current day’s variation margin receivable or payable is disclosed as an asset or liability on the Statement of Financial Condition. The Fund defines cash and cash equivalents to be highly liquid investments, with original maturities of three months or less when purchased. As of December 31, 2014, the Fund had cash held with the Predecessor Commodity Broker of $68,613,950 which was on deposit to satisfy the Fund’s variation margin requirement on open futures contracts. There was no cash held by the Commodity Broker as of March 31, 2015. There were no cash equivalents held by the Fund as of March 31, 2015 and December 31, 2014.

(h) Receivable/(Payable) for Shares Issued and Redeemed

On any business day, an Authorized Participant may place an order to create or redeem Shares of the Fund. Cash settlement occurs at the creation order settlement date or the redemption order settlement date as discussed in Note 7.

(i) 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 Managing Owner has reviewed all of the Fund’s open tax years and major jurisdictions and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns. The Fund is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. On an ongoing basis, the Managing Owner will monitor the Fund’s tax positions taken under the interpretation (and consult with its tax counsel from time to time when appropriate) to determine if adjustments to conclusions are necessary based on factoring including, but not limited to, on-going analysis of tax law, regulation, and interpretations thereof. The major tax jurisdiction for the Fund and the earliest tax year subject to examination: United States, 2011.

(j) Futures Contracts

All commodity futures contracts are held and used for trading purposes. Commodity futures contracts are recorded on trade date. Open contracts are recorded in the statement of financial condition at fair value on trade date and on each successive date as well as on the last business day of each of the periods presented, which represent 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.

The Value of Derivative Instruments is as follows:

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

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. 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 Obligations will be sold to make additional cash available. The table below summarizes the average monthly notional value of futures contracts outstanding during the period:

The Fund utilizes derivative instruments to achieve its investment objective. For financial reporting purposes, the Fund offsets financial assets and financial liabilities that are subject to netting arrangements. In order for an arrangement to be eligible for netting, the Fund must have a basis to conclude that such netting arrangements are legally enforceable. The following table presents derivative instruments that are either subject to an enforceable netting agreement or offset by collateral arrangements as of March 31, 2015, net by contract:

The following table presents derivative instruments that are either subject to an enforceable netting agreement or offset by collateral arrangements as of December 31, 2014, net by contract:

(k) 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 and the Predecessor Commodity Broker, as applicable, were less than $6.00 and $10.00 per round-turn trade for the Three Months Ended March 31, 2015 and 2014, respectively.

(l) 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. Prior to the Closing Date, the Predecessor Managing Owner assumed all routine operational, administrative and other ordinary expenses of the Fund. Accordingly, all such expenses are not reflected in the statement of income and expenses of the Fund.

(m) Organizational and Offering Costs

All organizational and offering expenses (including continuous offering expenses for the offering of the Shares) incurred by the Fund were assumed by either the Predecessor Managing Owner or the Managing Owner. The Fund is not responsible to either the Predecessor Managing Owner or the Managing Owner for the reimbursement of organizational and offering costs (including continuous offering expenses for the offering of the Shares).

(n) 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, 2015 and 2014, the Fund did not incur such expenses.

(6) Financial Instrument Risk

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

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

Credit risk is the possibility that a loss may occur due to the failure of 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.

On any business day, an Authorized Participant may place an order with the Administrator who serves as the Fund’s transfer agent (“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 nonrefundable 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) of the Fund requested in the Authorized Participant’s redemption order as of the closing time of the NYSE Arca or the last to close of the exchanges on which 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.

(8) 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. 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, 2015 or 2014.

(9) Commitments and Contingencies

The Managing Owner, either in its own capacity or in its capacity as the Managing Owner and on behalf of the Fund, has entered into various service agreements that contain a variety of representations, or provide indemnification provisions related to certain risks service providers undertake in performing services which are in the best interests of the Fund. As of March 31, 2015 and December 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.

(10) Net Asset Value and Financial Highlights

The Fund is presenting the following net asset value and financial highlights related to investment performance for a Share outstanding for the Three Months Ended March 31, 2015 and 2014. The net investment income (loss) and total expense ratios are calculated using average net asset value. The net asset value presentation is calculated using average daily Shares outstanding. 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

On October 24, 2014, DB Commodity Services LLC, a Delaware limited liability company (“DBCS”), DB U.S. Financial Markets Holding Corporation (“DBUSH”) and Invesco PowerShares Capital Management LLC (“Invesco”) entered into an Asset Purchase Agreement (the “Agreement”). DBCS is a wholly-owned subsidiary of DBUSH. DBCS agreed to transfer and sell to Invesco all of DBCS’ interest in the PowerShares DB Oil Fund (the “Fund”), including the sole and exclusive power to direct the business and affairs of the Fund, as well as certain other assets of DBCS pertaining to the management of the Fund, pursuant to the terms and conditions of the Agreement (the “Transaction”).

The Transaction was consummated on February 23, 2015 (the “Closing Date”). Invesco now serves as the managing owner (the “Managing Owner”), commodity pool operator and commodity trading advisor of the Fund, in replacement of DBCS (the “Predecessor Managing Owner”).

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

As of the date of this Report, each of Deutsche Bank Securities Inc., Merrill Lynch Professional Clearing Corp., Newedge USA LLC, Virtu Financial Capital Markets 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 Fund pursues its investment objective by investing in a portfolio of exchange-traded futures contracts that expire in a specific month and trade on a specific exchange (the “Index Contracts”), in the single commodity comprising the Index (the “Index Commodity”). The single Index Commodity is Light Sweet Crude Oil (WTI). The Index is composed of notional amounts of the Index Commodity. The Fund also holds United States Treasury Obligations and other high credit quality short-term fixed income securities for deposit with the Fund’s Commodity Broker as margin. After the Closing Date, the aggregate notional value of the futures contracts owned by the Fund is expected to approximate the aggregate net asset value of the Fund, as opposed to the aggregate Index value.

The Commodity Futures Trading Commission (the “CFTC”) and/or commodity exchanges, as applicable, impose position limits on market participants trading in the commodity included in the Index. As disclosed in the Fund’s Prospectus, if the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to the Index Commodity by investing in a specific Index Contract, the Fund may invest in (i) a futures contract referencing the Index Commodity other than the Index Contract or, in the alternative, invest in (ii) other futures contracts not based on the Index Commodity ((i) and (ii) collectively, the “Alternative Futures Contracts”) if, in the commercially reasonable judgment of the Managing Owner, such Alternative Futures Contracts tend to exhibit trading prices that correlate with the Index Commodity. Please see http://www.invescopowershares.com with respect to the most recently available weighted composition of the Fund and the composition of the Index on the Base Date.

No purchaser, seller or holder of the Shares of this Fund, or any other person or entity, should use or refer to any Deutsche Bank trade name, trademark or service mark to sponsor, endorse, market or promote this Fund without first contacting Deutsche Bank to determine whether Deutsche Bank’s permission is required. Under no circumstances may any person or entity claim any affiliation with Deutsche Bank without the written permission of Deutsche Bank.

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

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

The Index includes provisions for the replacement of futures contracts as they approach maturity. This replacement takes place over a period of time in order to lessen the impact on the market for the futures contracts being replaced. With respect to the Index Commodity, the Fund employs a rule-based approach when it “rolls” from one futures contract to another. The Index replaces the underlying futures contracts on an “optimum yield” basis. Rather than select a new futures contract based on a predetermined schedule (e.g., monthly), the Index Commodity rolls to the futures contract which generates the best possible “implied roll yield.” The futures contract with a delivery month within the next thirteen months which generates the best possible implied roll yield will be included in the Index. As a result, the Fund is able to potentially maximize the roll benefits in backwardated markets and minimize the losses from rolling in contangoed markets for the Index Commodity.

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

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

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

On the first New York business day (the “Verification Date”) of each month, the Index Commodity futures contract will be tested in order to determine whether to continue including it in the Index. If the Index Commodity futures contract requires delivery of the underlying commodity in the next month, known as the Delivery Month, a new Index Commodity futures contract will be selected for inclusion in the Index. For example, if the first New York business day is October 1, 2015, and the Delivery Month of the Index Commodity futures contract currently in such Index is November 2015, a new Index Commodity futures contract with a later Delivery Month will be selected.

For the underlying Index Commodity of the Index, the new Index Commodity futures contract selected will be the Index Commodity futures contract with the best possible “implied roll yield” based on the closing price for each eligible Index Commodity futures contract. Eligible Index Commodity futures contracts are any Index Commodity futures contracts having a Delivery Month (i) no sooner than the month after the Delivery Month of the Index Commodity futures contract currently in the Index, and (ii) no later than the 13^th month after the Verification Date. For example, if the first New York business day is October 1, 2015 and the Delivery Month of an Index Commodity futures contract currently in the Index is November 2015, the Delivery Month of an eligible new Index Commodity futures contract must be between December 2015 and October 2016. 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 selection of the replacement futures contract, the monthly roll for the Index Commodity subject to a roll in that particular month unwinds the old futures contract and enters a position in the new futures contract. This takes place between the 2nd and 6th Index Business Day of the month.

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

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

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

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

Margin Calls

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

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

Table of Contents

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.

Performance Summary

This Report covers the three months ended March 31, 2015 and 2014 (hereinafter referred to as the “Three Months Ended March 31, 2015” and the “Three Months Ended March 31, 2014”, respectively). The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC (the “NYSE Alternext”)) on January 5, 2007, and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

Performance of the Fund and the exchange-traded Shares are detailed below in “Results of Operations”. The Fund’s performance information from inception up to and excluding the Closing Date is a reflection of the performance associated with the Predecessor Managing Owner. The Managing Owner has served as managing owner of the Fund since the Closing Date, and the Fund’s performance information since the Closing Date is a reflection of the performance associated with the Managing Owner. Past performance of the Fund is not necessarily indicative of future performance.

The Index is intended to reflect the change in market value of the Index Commodity. In turn, the Index is intended to reflect the oil sector. The DBIQ Optimum Yield Crude Oil Index Total Return™ (the “DBIQ-OY CL 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 CL TR™ and Underlying Index Commodity Returns for the Three Months Ended March 31, 2015 and 2014” below provides an overview of the changes in the closing levels of the DBIQ-OY CL TR™ by disclosing the change in market value of the underlying component Index Commodity through a “surrogate” (and analogous) index plus 3-month United States Treasury Obligations returns. Please note also that the Fund’s objective is to track the Index (not the DBIQ-OY CL TR™), and the Fund does not attempt to outperform or underperform the Index.

Summary of the DBIQ-OY CL TR™ and Underlying Index Commodity

Returns for the Three Months Ended March 31, 2015 and 2014

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

Net Asset Value

Net asset value means the total assets of the Fund, including, but not limited to, all futures, cash and investments less total liabilities of the Fund, each determined on the basis of U.S. generally accepted accounting principles (“U.S. GAAP”), 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.

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. GAAP 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. U.S. GAAP defines fair value as 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, under current market conditions.

U.S. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level. See Note 5(c) within the financial statements in Item 1 for further information.

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

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

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

Market Risk

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

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

Credit Risk

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

The Commodity Broker, when acting as the Fund’s futures commission merchant in accepting orders for the purchase or sale of domestic futures contracts, is required by CFTC regulations to separately account for and segregate as belonging to the Fund all assets of the Fund relating to domestic futures trading and the Commodity Broker is not allowed to commingle such assets with other assets 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 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 $(124.8) million and $8.3 million for the Three Months Ended March 31, 2015 and 2014, respectively. These amounts primarily include net income (loss) and net purchases and sales of United States Treasury Obligations which are held at fair value on the statement of financial condition.

During the Three Months Ended March 31, 2015, $305.8 million was paid to purchase United States Treasury Obligations and $270.0 million was received from sales and maturing United States Treasury Obligations. During the Three Months Ended March 31, 2014, $282.0 million was paid to purchase United States Treasury Obligations and $290.0 million was received from sales and maturing United States Treasury Obligations. Unrealized appreciation/depreciation on United States Treasury Obligations and futures increased (decreased) net cash provided by (used for) operating activities by $(21.5) million and $(10.4) million during the Three Months Ended March 31, 2015 and 2014, respectively.

Financing Activities

The Fund’s net cash flow provided by (used for) financing activities was $364.1 million and $(11.2) million during the Three Months Ended March 31, 2015 and 2014, respectively. This included $364.1 from the sale of Shares to Authorized Participants during the Three Months Ended March 31, 2015 and $11.2 million from Shares redeemed by Authorized Participants during the Three Months Ended March 31, 2014.

Results of Operations

FOR THE THREE MONTHS ENDED MARCH 31, 2015 AND 2014

The Fund was launched on January 3, 2007 at $25.00 per Share. The Shares traded on the NYSE Alternext from January 5, 2007 to November 25, 2008 and have been trading on the NYSE Arca since November 25, 2008. The Fund’s performance information from inception up to and excluding the Closing Date is a reflection of the performance associated with the Predecessor Managing Owner. The Managing Owner has served as managing owner of the Fund since the Closing Date, and the Fund’s performance information since the Closing Date is a reflection of the performance associated with the Managing Owner. Past performance of the Fund is not necessarily indicative of future performance.

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

The Index is a set of rules applied to a body of data and does not represent the results of actual investment or trading. The Index is frictionless, in that it does not take into account fees or expenses associated with investing in the Fund. Also, because it does not represent actual futures positions, the Index is not subject to, and does not take into account the impact of, speculative position limits or certain other similar limitations on the ability of the Fund to trade the Index Commodity. The “TR” version of the Index includes an

Table of Contents

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 is currently subject to accountability levels and may be subject to speculative position limits and certain other limitations on its ability to trade the Index Commodity, which may compel the Fund to trade futures or other instruments that are not the Index Commodity as proxies for the Index Commodity. The interest rate actually earned by the Fund over any period may differ from the assumed amount of interest income factored into the “TR” version of the Index over the same period. All of these factors can contribute to discrepancies between changes in net asset value per Share and changes in the level of the Index over any period of time. The extent to which the Fund has invested at an aggregate notional level approximating the Index value as opposed to the Fund’s aggregate net asset value also may contribute to discrepancies. Fees and expenses always will tend to cause changes in the net asset value per Share to underperform changes in the value of the Index over any given period, all other things being equal. Actual interest income could be higher or lower than the assumed interest income factored into the “TR” version of the Index, and therefore could cause changes in the net asset value per Share to outperform or underperform changes in the value of the “TR” version of the Index over any given period, all other things being equal. Similarly, trading futures or other instruments that are not the Index Commodity as proxies for the Index Commodity could cause changes in the net asset value per Share to outperform or underperform changes in the value of the Index over any given period, all other things being equal.

The Fund seeks to track the changes, whether positive or negative, in the level of the DBIQ Optimum Yield Crude Oil Index Excess Return™ (the “DBIQ-OY CL ER™”, or the “Index”), over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. The Index is intended to reflect the change in market value of the crude oil sector. The single commodity comprising the Index is Light Sweet Crude Oil (WTI) (the “Index Commodity”). The Shares are designed for investors who want a cost-effective and convenient way to invest in commodity futures on U.S. and non-U.S. markets.

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

WHILE THE FUND’S OBJECTIVE IS NOT TO GENERATE PROFIT THROUGH ACTIVE PORTFOLIO MANAGEMENT, BUT IS TO TRACK THE INDEX, BECAUSE THE INDEX WAS ESTABLISHED IN MAY 2006 (RENAMED OCTOBER 2010), CERTAIN INFORMATION RELATING TO THE INDEX CLOSING LEVELS MAY BE CONSIDERED TO BE “HYPOTHETICAL.” HYPOTHETICAL INFORMATION MAY HAVE CERTAIN INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW.

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

WITH RESPECT TO INDEX DATA, ONE OF THE LIMITATIONS OF HYPOTHETICAL INFORMATION IS THAT IT IS GENERALLY PREPARED WITH THE BENEFIT OF HINDSIGHT. TO THE EXTENT THAT INFORMATION PRESENTED HEREIN RELATES TO THE PERIOD DECEMBER 1988 THROUGH APRIL 2006, THE INDEX CLOSING LEVELS REFLECT THE APPLICATION OF THE INDEX METHODOLOGY, AND SELECTION OF INDEX COMMODITY, IN HINDSIGHT.

NO HYPOTHETICAL RECORD CAN COMPLETELY ACCOUNT FOR THE IMPACT OF FINANCIAL RISK IN ACTUAL TRADING. FOR EXAMPLE, THERE ARE NUMEROUS FACTORS, INCLUDING THOSE DESCRIBED UNDER ITEM 1A. “RISK FACTORS” SET FORTH IN THE FUND’S ANNUAL REPORT ON FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 2014, 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 AND ITS TRADING PRINCIPALS HAVE LIMITED EXPERIENCE MANAGING THE DAY-TO-DAY OPERATIONS FOR THE FUND AND, PRIOR TO THE CLOSING DATE, HAD ONLY MANAGED AN EXCHANGE-TRADED FUND THAT RELATES TO A BROAD-BASED COMMODITY INDEX FOR A SHORT PERIOD. BECAUSE THERE ARE LIMITED ACTUAL PERFORMANCE RESULTS OF THE MANAGING OWNER THAT ARE COMPARABLE TO THE INDEX CLOSING LEVELS SET FORTH HEREIN, PROSPECTIVE INVESTORS SHOULD BE PARTICULARLY WARY OF PLACING UNDUE RELIANCE ON INDEX RESULTS IN RESPECT OF ANY PERIOD. FOR THE AVOIDANCE OF DOUBT, NONE OF THE PERFORMANCE RELATED INFORMATION THAT IS COVERED BY THE PERIOD OF THIS REPORT UP TO AND EXCLUDING THE CLOSING DATE CAN BE ATTRIBUTED TO THE MANAGING OWNER.

THE PREDECESSOR MANAGING OWNER, AN INDIRECT WHOLLY OWNED SUBSIDIARY OF DEUTSCHE BANK AG, COMMENCED OPERATIONS IN JANUARY 2006. AS THE PREDECESSOR MANAGING OWNER, THE PREDECESSOR MANAGING OWNER AND ITS TRADING PRINCIPALS MANAGED THE DAY-TO-DAY OPERATIONS FOR THE FUND FROM INCEPTION UP TO AND EXCLUDING THE CLOSING DATE. 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 INDEX RESULTS IN RESPECT OF ANY PERIOD. FOR THE AVOIDANCE OF DOUBT, NONE OF THE PERFORMANCE RELATED INFORMATION THAT IS COVERED BY THE PERIOD OF THIS REPORT ON AND AFTER THE CLOSING DATE CAN BE ATTRIBUTED TO THE PREDECESSOR MANAGING OWNER.

Fund Share Net Asset Performance

For the Three Months Ended March 31, 2015, the net asset value of each Share decreased 12.96% from $15.51 per Share to $13.50 per Share. A decrease in the price of light sweet crude oil futures contracts during the Three Months Ended March 31, 2015 resulted in an overall 12.52% decrease in the level of the DBIQ Optimum Yield Crude Oil Index Total Return™.

Net loss for the Three Months Ended March 31, 2015 was $38.6 million, primarily resulting from net realized loss of $59.2 million, net change in unrealized gain of $21.5 million and operating expenses of $0.9 million.

For the Three Months Ended March 31, 2014, the net asset value of each Share increased 3.54% from $27.69 per Share to $28.67 per Share. An increase in the price of light sweet crude oil futures contracts during the Three Months Ended March 31, 2014 resulted in an overall 3.59% increase in the level of the DBIQ Optimum Yield Crude Oil Index Total Return™.

Net income for the Three Months Ended March 31, 2014 was $10.7 million, primarily resulting from net realized gain of $0.8 million, net change in unrealized gain of $10.4 million and operating expenses of $0.6 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. For the avoidance of doubt, for purposes of the reporting period up to and excluding the Closing Date, all Management Fees and commission payments were paid to the Predecessor Managing Owner and the Predecessor Commodity Broker, respectively. Since the Closing, the Managing Owner has served as managing owner of the Fund and the Commodity Broker has served as the Fund’s futures clearing broker and all Management Fee accruals and commission accruals since the Closing Date have been paid to the Managing Owner and the Commodity Broker, respectively.

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.

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.
