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

The Fund offers common units of beneficial interest (the “Shares”) only to certain eligible financial institutions (the “Authorized Participants”) in one or more blocks of 200,000 Shares, called a Basket. The Fund commenced investment operations on February 15, 2007. The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC (the “NYSE Alternext”)) on February 20, 2007 and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

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.

The Fund establishes long positions in certain futures contracts (the “DX Contracts”), with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank Long US Dollar Index (USDX^®) Futures Index — Excess Return, the “Long Index” or the “Index”, over time. The performance of the Fund also is intended to reflect the excess, if any, of its 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 calculated to reflect the changes in market value over time, whether positive or negative, in long positions on DX Contracts. DX Contracts are traded through the currency markets of ICE Futures U.S. (formerly known as the New York Board of Trade^®), under the symbol “DX.” The changes in market value over time, whether positive or negative, of the DX Contracts are related to the changes, whether positive or negative, in the level of the U.S. Dollar Index^® (the “USDX^®”). The Index provides a general indication of the international value of the U.S. dollar relative to the six major world currencies (the “Index Currencies”), which comprise the USDX^® — Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.

The Fund does not borrow money to increase leverage. As of June 30, 2014 and December 31, 2013, the Fund had $711,028,744 (or 100%) and $667,435,214 (or 100%), respectively, of its holdings of cash, United States Treasury Obligations and unrealized appreciation/depreciation on futures contracts on deposit with its Commodity Broker. Of this, $7,872,480 (or 1.11%) and $8,243,730 (or 1.23%), 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 on DX Contracts as of June 30, 2014 and December 31, 2013, respectively. For additional information, please see the unaudited Schedule of Investments as of June 30, 2014 and the audited Schedule of Investments as of December 31, 2013 for details of the Fund’s portfolio holdings.

Trademark applications in the United States are pending with respect to both the Fund and aspects of the Index. The Fund and the Managing Owner have been licensed by Deutsche Bank AG London (the “Index Sponsor”) to use certain trademarks. Deutsche Bank AG London is an affiliate of the Fund and the Managing Owner.

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 serves as the Fund’s commodity pool operator, commodity trading advisor and managing owner, and is an indirect wholly-owned subsidiary of Deutsche Bank AG. The Fund pays the Managing Owner a management fee (the “Management Fee”), monthly in arrears, in an amount equal to 0.75% per annum of the daily net asset value of the Fund. During the Three Months Ended June 30, 2014 and 2013, the Fund incurred Management Fees of $1,263,467 and $1,316,793, respectively. Management Fees incurred during the Six Months Ended June 30, 2014 and 2013 by the Fund were $2,548,683 and $2,522,947, respectively. As of June 30, 2014 and December 31, 2013, Management Fees payable to the Managing Owner were $426,783 and $445,639, respectively.

Deutsche Bank Securities Inc., a Delaware corporation, serves as the Fund’s futures clearing broker (the “Commodity Broker”). The Commodity Broker is an indirect wholly-owned subsidiary of Deutsche Bank AG and is an affiliate of the Managing Owner. In its capacity as clearing broker, the Commodity Broker executes and clears each of the Fund’s futures transactions and performs certain administrative and custodial services for the Fund. As custodian of the Fund’s assets, 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 June 30, 2014 and 2013, the Fund incurred brokerage fees of $100,231 and $135,787, respectively. Brokerage fees incurred during the Six Months Ended June 30, 2014 and 2013 by the Fund were $212,912 and $266,197, respectively. As of June 30, 2014 and December 31, 2013, brokerage fees payable were $2,128 and $1,456, respectively.

The Bank of New York Mellon (the “Administrator”) has been appointed by the Managing Owner as 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 June 30, 2014 and December 31, 2013, there were no Fund assets held by the Administrator.

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.

Under the License Agreement among Invesco PowerShares Capital Management LLC (the “Licensor”) and the Managing Owner in its own capacity and in its capacity as managing owner of the Fund, the Fund (the Fund and the Managing Owner, collectively, the “Licensees”), the Licensor granted to each Licensee a non-exclusive license to use the “PowerShares^®” trademark (the “Trademark”) anywhere in the world, solely in connection with the marketing and promotion of the Fund and to use or refer to the Trademark in connection with the issuance and trading of the Fund as necessary.

Through a marketing agreement between the Managing Owner and Invesco Distributors, Inc. (“Invesco Distributors”), an affiliate of Invesco PowerShares Capital Management LLC, the Managing Owner, on behalf of the Fund, has appointed Invesco Distributors as a marketing agent. Invesco Distributors assists the Managing Owner and the Administrator with certain functions and duties such as providing various educational and marketing activities regarding the Fund, primarily in the secondary trading market, which activities include, but are not limited to, communicating the Fund’s name, characteristics, uses, benefits, and risks, consistent with the Fund’s prospectus. Invesco Distributors will not open or maintain customer accounts or handle orders for the Fund. Invesco Distributors engages in public seminars, road shows, conferences, media interviews, and distributes sales literature and other communications (including electronic media) regarding the Fund.

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.

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.

United States Treasury Obligations and currency 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:

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 currency futures contracts, the Fund uses unadjusted quoted market prices in active markets. United States Treasury Obligations and currency 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 currency futures contracts.

There were no Level 2 or Level 3 holdings as of June 30, 2014 and December 31, 2013. The Fund’s policy is to recognize transfers in and out of the valuation levels as of the end of the reporting period. There were no transfers between levels during the periods presented.

The Fund deposits cash and United States Treasury Obligations with its Commodity Broker subject to Commodity Futures Trading Commission (the “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.

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’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 June 30, 2014, the Fund had cash held by the Commodity Broker of $21,212,528, of which $9,155,191 was on deposit to satisfy the Fund’s negative variation margin on open futures contracts. As of December 31, 2013, the Fund had cash held by the Commodity Broker of $12,100,937, of which $579,635 was on deposit to satisfy the Fund’s negative variation margin on open futures contracts. There were no cash equivalents held by the Fund as of June 30, 2014 and December 31, 2013.

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.

Management of the Fund has reviewed all 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 Funds are 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, management will monitor its 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 factors 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, 2010.

All currency futures contracts are held and used for trading purposes. Currency 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 currency 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 three months ended June 30, 2014 and 2013, the average monthly notional market value of futures contracts held was $682.0 million and $754.5 million, respectively. For the six months ended June 30, 2014 and 2013, the average notional market value of futures contracts held was $686.1 million and $706.4 million, respectively.

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

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 master netting arrangements or similar agreements in the statements of financial condition. The following table presents the gross and net amounts of these assets and liabilities with any offsets to reflect the Fund’s ability to enforce the master netting agreements at June 30, 2014:

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

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.

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 $12.00 per round-turn trade for the Three Months Ended June 30, 2014 and 2013 and the Six Months Ended June 30, 2014 and 2013.

Pursuant to a written agreement, 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 as part of its management fee. Accordingly, all such expenses are not reflected in the statement of income and expenses of the Fund.

Pursuant to a written agreement, 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.

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 June 30, 2014 and 2013 and the Six Months Ended June 30, 2014 and 2013, the Fund did not incur such expenses.

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 statement of financial condition, 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 exchange-listed currency 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 currency 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 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 1:00 p.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.

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 1:00 p.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.

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.

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 June 30, 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.

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 June 30, 2014 and 2013 and for the Six Months Ended June 30, 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 average 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.

The Fund evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the financial statements were issued. This evaluation did not result in any subsequent events that necessitated disclosures and/or adjustments.

Words such as “anticipate,” “expect,” “intend,” “plan,” “believe,” “seek,” “outlook” and “estimate,” as well as similar words and phrases, signify forward-looking statements. PowerShares DB US Dollar Index Bullish Fund’s (the “Fund”) forward-looking statements are not guarantees of future results and conditions and important factors, risks and uncertainties may cause our actual results to differ materially from those expressed in our forward-looking statements.

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

The Fund establishes long positions in certain futures contracts (the “DX Contracts”) with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank Long US Dollar Index (USDX^®) Futures Index–Excess Return, the “Long Index” or the “Index”, over time. The performance of the Fund also is intended to reflect the excess, if any, of its 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 calculated to reflect the changes in market value over time, whether positive or negative, in long positions on DX Contracts. DX Contracts are traded through the currency markets of ICE Futures U.S. (formerly known as the New York Board of Trade^®), under the symbol “DX.” The changes in market value over time, whether positive or negative, of the DX Contracts are related to the changes, whether positive or negative, in the level of the U.S. Dollar Index^® (the “USDX^®”). The Index provides a general indication of the international value of the U.S. dollar relative to the six major world currencies (each an “Index Currency,” and collectively, the “Index Currencies”) which comprise the USDX^®–Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.

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, ABN AMRO Clearing Chicago (USA) LLC, Virtu Financial BD LLC, Knight Capital Americas LLC, Timber Hill LLC, Morgan Stanley & Co.

The Shares are designed for investors who want a cost-effective and convenient way to invest in a group of currency futures on U.S. and non-U.S. markets.

As of the date of this Report, the DX Contracts are not subject to speculative position limits. There can be no assurance that the DX Contracts will not become subject to speculative position limits. Should the Fund become subject to speculative position limits with respect to its DX Contracts holdings, the Fund’s ability to issue new Baskets or the Fund’s ability to reinvest income in additional DX Contracts may be limited to the extent that these activities would cause the Fund to exceed the potential future position limits. Limiting the size of the Fund may affect the correlation between the price of the Shares, as traded on the NYSE Arca, and the net asset value of the Fund. That is, the inability to create additional Baskets could result in Shares trading at a premium or discount to the net asset value of the Fund.

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 DX Contracts, the Fund may:

if, in the commercially reasonable judgment of the Managing Owner, such above instruments tend to exhibit trading prices that correlate with the DX Contract.

The performance of the Fund also is intended to reflect the excess, if any, of its interest income from its holdings of United States Treasury and other high credit quality short-term fixed income securities over its expenses.

The Fund is an index tracking fund and does not utilize any trading system, whether discretionary, systematic or otherwise. The Index is calculated to reflect the changes in market value over time, whether positive or negative, of long positions in DX Contracts. The Fund seeks to track the Index by establishing long positions in DX Contracts accordingly. Therefore, the Managing Owner serves in an administrative role in order to ensure that the Fund invests in a manner that seeks to track the Index.

The Index is designed to reflect the changes in market value over time, whether positive or negative, from investing in the first to expire DX Contracts whose changes in market value over time, whether positive or negative, in turn, are tied to the USDX^®. The first to expire DX Contracts are the futures contracts that expire in March, June, September and December. DX Contracts are traded exclusively through ICE Futures U.S., under the symbol “DX.”

The changes in market value over time, whether positive or negative, of DX Contracts are related to the Index Currencies. (Although the Index tracks the changes in market value over time, whether positive or negative, of long positions in the first to expire DX Contracts, the closing level of the Index is in effect, and in part, a reflection of the changes, whether positive or negative, in the level of the U.S. dollar relative to a basket of the underlying Index Currencies.) The Index Currencies are Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. The Index Currencies represent the currencies of the major trading partners of the U.S. (and represent the currencies of 17 countries, 12 countries of the Euro zone plus five other countries).

The USDX^® is composed of notional amounts of each Index Currency. The notional amounts of the Index Currencies included in the USDX^® reflect a geometric weighted average of the change in the Index Currencies’ exchange rates against the U.S. dollar relative to March 1973. March 1973 was chosen as the base period of the USDX^® because it represents a significant milestone in foreign exchange history when the world’s major trading nations allowed their currencies to float freely against each other.

The fair value of DX Contracts is based on foreign exchange futures prices for the underlying Index Currencies. The fair value of DX Contracts is calculated in the same way as a spot index. DX Contracts, similar to single currency futures contracts, will trade at a forward premium or discount based on the interest rate differential between the U.S. dollar and the Index Currencies.

Volatility of the USDX^® has been historically comparable in range and variability to a broad-based, multi-capitalization stock index future. The DX Contract price is sized at $1,000 times the USDX^® closing level. Thus, if the USDX^® closing level is 100.00, the DX Contract will be valued $100,000. If the USDX^® closing level is 112.50, each DX Contract will have a $112,500 value.

The Index reflects the changes in market value over time, whether positive or negative, of long positions in the first to expire DX Contracts. In turn, the changes in market value over time, whether positive or negative, of DX Contracts are related to the changes, positive and negative, in the level of the USDX^®.

The USDX^® provides a general indication of the international value of the U.S. dollar and is composed of notional amounts of each of the Index Currencies. The notional amounts of each Index Currency included in the USDX^® are weighted to reflect the currencies of the largest trading partners of the U.S. These largest trading partners constitute the bulk of international trade with the United States and have well-developed foreign exchange markets with rates freely determined by market participants. In addition, many currencies not included in the USDX^® move in close correlation with those that are included. The USDX^® is computed 24 hours a day, seven days a week based on exchange rates supplied to Reuters by some 500 banks worldwide.

The following table reflects the index base weights (the “Index Base Weights”) of each Index Currency as of March 1973 with respect to the USDX^®:

The USDX^® has been calculated since inception in March 1973. The closing level at inception was 100.00.

The Euro was included in the USDX^® in 1999 and replaced the following currencies that were originally included in the USDX^®: Belgian Franc, Dutch Guilder, German Mark, French Franc and Italian Lira.

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.

The Index reflects the changes in market value over time, whether positive or negative, of long positions in the first to expire DX Contracts relative to the value of the dollar as of December 31, 1986 (the “Base Date”), which expire in March, June, September and December. On the Base Date, the closing level was 100.00. Although the DX Contract started trading in 1985, the Base Date of December 31, 1986 was selected because reasonably reliable pricing data was not available prior to December 31, 1986. A quote of “105.50” means the U.S. dollar’s value has risen 5.50% since the Base Date relative to the underlying basket of Index Currencies which comprise the USDX^®.

The Index Sponsor calculates the closing level of the Index on both an excess return basis and a total return basis. The excess return index reflects the changes in market value over time, whether positive or negative, of the DX Contracts. The total return is the sum of the changes in market value over time, whether positive or negative, of the DX Contracts plus the return of 3-month U.S. Treasury bills. The closing levels of the Index have been calculated using historic exchange closing price data of the DX Contracts since the Base Date.

The use of long positions on DX Contracts in the construction of the Long Index causes the Long Index to rise as a result of any upward price movement in the DX Contracts. In turn, this appreciation in the long DX Contracts reflects the rise of the U.S. dollar relative to the underlying basket of Index Currencies which comprise the USDX^®.

Since the Base Date, the Long Index closing level has ranged on a daily basis from as high as 100.58 on January 5, 1987 to as low as 51.94 on April 29, 2011. Past Index levels are not necessarily indicative of future Index levels.

The underlying DX Contracts of the Index are rolled quarterly over three consecutive business days starting on the Wednesday prior to the applicable IMM Date (each an “Index Roll Day”). “IMM Date” means the third Wednesday of March, June, September and December, a traditional settlement date in the International Money Market.

There are no regularly scheduled adjustments or rebalancing of the USDX^®. The USDX^® has only been adjusted once, when the Euro was introduced as the common currency for the European Union (EU) bloc of countries. Without any other adjustments, the combination of components and their respective weightings in the USDX^® have yielded performance results similar to other commonly used US dollar indexes, whether those index methodologies are based on trade weights or capital flow weights.

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

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

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

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

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

Once a position has been established on a futures exchange, “variation margin” generally is credited or assessed at least daily to reflect changes in the value of the position, 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.

This Report covers the three months ended June 30, 2014 and 2013 (hereinafter referred to as the “Three Months Ended June 30, 2014” and the “Three Months Ended June 30, 2013”, respectively) and the six months ended June 30, 2014 and 2013 (hereinafter referred to as the “Six Months Ended June 30, 2014” and the “Six Months Ended June 30, 2013”, respectively). The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC (the “NYSE Alternext”)) on February 20, 2007, and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

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

The Index provides a general indication of the international value of the U.S. dollar relative to the six major world currencies (the “Index Currencies”), which comprise the USDX^®–Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. The Deutsche Bank Long US Dollar Index (USDX^®) Futures Index–Total Return (Long Index-TR), consists of the Index plus 3-month United States Treasury bills returns. Past Index results are not necessarily indicative of future changes, positive or negative, in the Index closing levels.

The section “Summary of Deutsche Bank Long US Dollar Index (USDX^®) Futures Index–Total Return and Underlying DX Contract Returns for the Three Months Ended June 30, 2014 and 2013 and the Six Months Ended June 30, 2014 and 2013” below provides an overview of the changes in the closing levels of the Index by disclosing the change in closing levels of the Index itself and the underlying DX Contracts of the Index. Please note also that the Fund’s objective is to track the Index (not the Long Index-TR™) and the Fund does not attempt to outperform or underperform the Index.

Summary of Deutsche Bank Long US Dollar Index (USDX^®) Futures Index–Total Return and Underlying DX Contract

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 Deutsche Bank Long US Dollar Index (USDX^®) Futures Index–Total Return (the “Long Index-TR”). The only difference between the Index and the Long Index-TR is that the Index does not include interest income from a hypothetical basket of fixed income securities while the Long Index-TR does include such a component. Thus, the difference between the Index and the Long Index-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 Long Index-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 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 currency futures contracts, and any other credit or debit accruing to the Fund but unpaid or not received by the Fund. All open currency futures contracts will be calculated at their then current market value, which will be based upon the settlement price for that particular currency futures contract traded on the applicable exchange on the date with respect to which net asset value is being determined; provided, that if a currency futures contract could not be liquidated on such day, due to the operation of daily limits or other rules of the exchange upon which that position is traded or otherwise, the Managing Owner may value such futures contract pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. The Managing Owner may in its discretion (and under circumstances, including, but not limited to, periods during which a settlement price of a futures contract is not available due to exchange limit orders or force majeure type events such as systems failure, natural or man-made disaster, act of God, armed conflict, act of terrorism, riot or labor disruption or any similar intervening circumstance) value any asset of the Fund pursuant to such other principles as the Managing Owner deems fair and equitable so long as such principles are consistent with normal industry standards. Interest earned on the Fund’s brokerage account is accrued monthly. The amount of any distribution is a liability of the Fund from the day when the distribution is declared until it is paid.

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

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 currency futures contracts and United States Treasury Obligations, both of which are recorded on a trade date basis 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 currency 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.

Trading in futures contracts involves the Fund entering into contractual commitments to purchase a particular currency at a specified date and price. The market risk associated with the Fund’s commitments to purchase currencies 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.

When the Fund enters into futures contracts, the Fund will be exposed to credit risk that the counterparty to the contract will not meet its obligations. The counterparty for futures contracts traded on United States 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.

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 currency futures 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 currency futures. 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 currency futures change. The balance of the net assets is held in the Fund’s trading account. Interest earned on the Fund’s interest-bearing funds is paid to the Fund.

The Fund’s currency futures contracts may be subject to periods of illiquidity because of market conditions, regulatory considerations or for other reasons. For example, commodity exchanges may limit fluctuations in certain 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 futures contract can neither be taken nor liquidated unless the traders are willing to effect trades at or within the limit. Although the DX Contracts that the Fund invests in are not currently subject to daily limits, the DX Contracts held by the Fund could become subject to such limits in the future. Such market conditions could prevent the Fund from promptly liquidating its currency 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).

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.

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 DX Contracts to match the fluctuations of the Index the Fund is tracking.

Net cash flow (used for) operating activities was ($43.6) million and ($208.4) million for the Six Months Ended June 30, 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.

During the Six Months Ended June 30, 2014, $1,373.9 million was paid to purchase United States Treasury Obligations and $1,331.0 million was received from sales and maturing contracts. During the Six Months Ended June 30, 2013, $1,550.8 million was paid to purchase United States Treasury Obligations and $1,343.0 million was received from sales and maturing United States Treasury Obligations. Unrealized appreciation on United States Treasury Obligations and futures decreased by $8.6 million and increased by $21.1 million during the Six Months Ended June 30, 2014 and 2013, respectively.

The Fund’s net cash flow provided by financing activities was $52.7 million and $156.1 million during the Six Months Ended June 30, 2014 and 2013, respectively. This included $173.1 million and $514.4 million from the sale of Shares to Authorized Participants during the Six Months Ended June 30, 2014 and 2013, respectively.

FOR THE THREE MONTHS ENDED JUNE 30, 2014 AND 2013 AND THE SIX MONTHS ENDED JUNE 30, 2014 AND 2013

The Fund was launched on February 15, 2007 at $25.00 per Share. The Shares traded on the NYSE Alternext from February 20, 2007 to November 25, 2008 and have been trading on the NYSE Arca since November 25, 2008.

The Fund seeks to track changes in the closing levels of the Deutsche Bank Long US Dollar Index (USDX^®) Futures Index–Excess Return, the “Long Index” 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 “UUP”), (ii) the Fund’s NAV (as reflected by the graph “UUPNV”), and (iii) the closing levels of the Index (as reflected by the graph “USDUPX”). Whenever the interest income earned by the Fund exceeds Fund expenses, the price of the Shares generally exceeds 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 continue to 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 (if applicable) or certain other similar limitations on the ability of the Fund to trade the DX Contracts. 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 (if applicable) and certain other limitations on its ability to trade the DX Contracts, which may compel the Fund to trade futures or other instruments that are not the DX Contracts as proxies for the DX Contracts. The interest rate actually earned by the Fund over any period may differ from the assumed amount of interest income factored into the “TR” version of the Index over the same period. All of these factors can contribute to discrepancies between changes in net asset value per Share and changes in the level of the Index over any period of time. Fees and expenses always will tend to cause changes in the net asset value per Share to underperform changes in the value of the Index over any given period, all other things being equal. Actual interest income could be higher or lower than the assumed interest income factored into the “TR” version of the Index, and therefore could cause changes in the net asset value per Share to outperform or underperform changes in the value of the “TR” version of the Index over any given period, all other things being equal. Similarly, trading futures or other instruments that are not the DX Contracts as proxies for the DX Contracts 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.

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 AUGUST 2006, 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 1986 THROUGH JULY 2006, THE INDEX CLOSING LEVELS REFLECT THE APPLICATION OF THE INDEX METHODOLOGY, AND SELECTION OF DX CONTRACTS, 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 CURRENCIES 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 MANAGING FUTURES ACCOUNTS AND RELATED PRODUCTS. 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.

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 currency 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 interest 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.

The Fund is designed to replicate positions in a currency futures 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 currencies.

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.

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.

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 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 June 30, 2014.

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

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

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 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.

Several factors may affect the price of the Index Currencies (which underlie the DX Contracts), including, but not limited to:

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.

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.

For purposes of this Item 4, all references to the “Fund” shall be read to specifically include the Fund and the Trust. Please note that the disclosure controls and procedures and internal control over financial reporting of the Trust are the aggregate disclosure controls and procedures and internal control over financial reporting of the Fund and that of PowerShares DB US Dollar Index Bearish Fund, each a series of the Trust.

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.

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

There are no material changes from risk factors as previously disclosed in the Annual Report on Form 10-K for the year ended December 31, 2013, filed March 3, 2014.

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

(c) The following table summarizes the redemptions by Authorized Participants during the Three Months Ended June 30, 2014:

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 June 30, 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.

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, four of which remained outstanding as of June 30, 2014, with the National Iranian Oil Company (NIOC), the National Petrochemical Company (NPC) 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 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 second quarter of 2014, approximately € 400 was paid into the escrow account. We, in our role as agent, distributed to the participants in the banking consortia € 22.3 million including portions attributable to us totaling approximately € 3.4 million.

We generated revenues in the second quarter of 2014 of approximately € 0.7 million in respect of these financing arrangements, of which approximately € 0.66 million consisted of escrow account revenues, € 30,000 consisted of loan interest revenues and € 10,000 consisted of fee revenues. The net profits were less than these amounts.

As of June 30, 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.

Our portion of the remaining loan facilities amounted to approximately € 29 million as of June 30, 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 June 30, 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 € 100 to the frozen account of the Syrian bank.

Payments Received. We received less than 15 payments adding up to approximately € 2 million in favor of non-Iranian clients in Germany, 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.

Operations of Iranian Bank Branches and Subsidiaries in Germany. Several Iranian banks, including Bank Melli Iran, Bank Saderat and Europäisch-Iranische Handelsbank, have branches or offices in Germany, even though their funds and other economic resources are frozen under European law. As part of the payment clearing system in Germany, when these branches or offices need to make payments in Germany 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 accepts fund transfers from these Iranian banks and disburses them to the applicable (mainly German) payees, some of whom hold accounts with us. In the second quarter of 2014, we received approximately € 1 million in such disbursements in approximately 200 transactions via the German Bundesbank 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.

Maintaining of Accounts for Iranian Consulates and Embassies. In the second 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 € 5 million in the second 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 € 13,000 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. In the second quarter of 2014 the revenues derived from this relationship were less than € 3,000 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.

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
