PART I



|ITEM 1. | BUSINESS
|------- | --------

Organization

PowerShares DB US Dollar Index Bearish 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 Second
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 proceeds from the offering of Shares
are invested in the Fund. 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).

Prior to the close of
business on December 31, 2010, the Fund invested substantially all of its assets in the DB US Dollar Index Bearish Master Fund (the Master Fund), a series of the DB US Dollar Index Master Trust (the Master Trust). After
the determination of the net asset value of the Master Fund on December 31, 2010, the Master Fund transferred and distributed all of its assets and liabilities and terminated. Effective January 1, 2011, the reorganized Fund will perform
all of the necessary functions in order to continue normal Fund operations. Accordingly, the collapse of the master-feeder structure will have no effect on the operations or processes of the Fund. All reference to historical results of the Fund
include the Master Fund where the context requires.

Fund Investment Overview

The Fund establishes short 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 Short US Dollar Index
(USDX®) Futures IndexExcess Return (the Short 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 short positions in 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 USDX® mark is a registered service mark owned by ICE Futures U.S., Inc.

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:



| |  |  | invest in a different month DX Contract other than the specific DX Contract that was originally required by the Index, or
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | invest in another futures contract substantially similar to the DX Contracts, if available, or
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | invest in the futures contracts referencing the Index Currencies, or
| | - |  | --------------------------------------------------------------------



| |  |  | invest in a forward agreement, swap, or other OTC derivative referencing the Index Currencies,
| | - |  | ----------------------------------------------------------------------------------------------

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

##### Table of Contents

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 short positions in DX Contracts. The Fund seeks to track the Index by establishing short 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 Fund does not employ leverage. As of December 31, 2010 and December 31, 2009, the Fund had $151,574,112 (or 100%) and $320,022,426 (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, $3,183,089 (or 2.10%) and $6,739,908 (or 2.11%), respectively, of the Funds holdings of cash and United
States Treasury Obligations are required to be deposited as margin in support of the Funds short futures positions on DX Contracts. For additional information, please see the audited Schedule of Investments as of December 31, 2010 and
2009 for details of the Funds portfolio holdings.

Index Description

The Index is designed to reflect the changes in market value over time, whether positive or negative, from investing
in the first to expire the 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 short 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 sponsor of the Short Index is Deutsche Bank AG London (the Index Sponsor).

USDX® Composition

The Index reflects the changes in market value over time, whether positive or negative, of short 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 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://dbfunds.db.com/udn/weights.aspx with respect to the most recently available weighted composition of the Fund.

Index Calculation

The Index reflects the changes in market value over time, whether positive or negative, of short positions in the first to expire DX Contracts relative to the value of the dollar as of December 31,
1986, or 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 short positions on DX Contracts in the construction of the Short Index causes the Short Index to rise as a result of any downward price movement in the DX Contracts. In turn, this appreciation in the short DX Contracts reflects the fall of
the U.S. dollar relative to the underlying basket of Index Currencies which comprise the USDX®.

Since the Base Date, the Short Index closing level has ranged on a daily basis from as high as 153.28 on April 22, 2008 to as low as
91.91 on July 5, 2001. Past Index levels are not necessarily indicative of future Index levels.

Index Rolls and Rebalancing of the USDX®

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.

DX Contracts are rolled on each Index Roll Day as follows:



| |  |  | On each Index Roll Day, 1/3 of the DX Contracts that will expire on the next IMM Date is bought back and positions in the DX Contracts that expire on
the IMM Date following the next IMM Date are sold short.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On each Index Roll Day, new notional holdings are calculated for the old DX Contracts leaving the Index as well as the new DX Contracts entering an
Index.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On all days that are not Index Roll Days, the notional holdings of the DX Contracts in the Index remain constant.
| | - |  | -----------------------------------------------------------------------------------------------------------------

There are no regularly scheduled adjustments or rebalancings of the USDX®. The USDX® has only been adjusted once, when the Euro, as noted above, 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.

General

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, and 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.

A patent application directed to the creation and operation of the Trust is
pending at the United States Patent and Trademark Office.

The Trustee

Under the Trust Agreement, Wilmington Trust Company, the Trustee of the Fund, has delegated to the Managing Owner the exclusive management
and control of all aspects of the business of the 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 Trustee is compensated by the Managing Owner. Under the Trust Agreement, the Managing Owner, from the assets of the Fund, will indemnify the Trustee for any liability or expense relating to the formation, operations and

##### Table of Contents

The CEAct and the CFTC also regulate the activities of commodity trading
advisors and commodity pool operators and the CFTC has adopted regulations with respect to certain of such persons activities. Pursuant to its authority, the CFTC requires a commodity pool operator (such as the Managing
Owner) to keep accurate, current and orderly records with respect to each pool it operates. The CFTC may suspend the registration of a commodity pool operator if the CFTC finds that the operator has violated the CEAct or regulations thereunder and
in certain other circumstances. Suspension, restriction or termination of the Managing Owners registration as a commodity pool operator would prevent it, until such time (if any) as such registration were to be reinstated, from managing, and
might result in the termination of, the Fund. The CEAct gives the CFTC similar authority with respect to the activities of commodity trading advisors, such as the Managing Owner. If the registration of a managing owner as a commodity trading advisor
were to be terminated, restricted or suspended, the managing owner would be unable, until such time (if any) as such registration were to be reinstated, to render trading advice to the Fund. The Fund is not registered with the CFTC in any capacity.

The CEAct requires all futures commission merchants, such as the Commodity Broker, to meet and maintain specified
fitness and financial requirements, segregate customer funds from proprietary funds and account separately for all customers funds and positions, and to maintain specified books and records open to inspection by the staff of the CFTC.

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

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

Pursuant to authority in the CEAct, the NFA has been formed and registered with the CFTC as a registered futures association. At the present time, the NFA is the only non-exchange
self-regulatory organization for commodities professionals. NFA members are subject to NFA standards relating to fair trade practices, financial condition, and consumer protection. As the self-regulatory body of the commodities industry, the NFA
promulgates rules governing the conduct of commodity professionals and disciplines those professionals who do not comply with such standards. The CFTC has delegated to the NFA responsibility for the registration of commodity trading advisors,
commodity pool operators, futures commission merchants, introducing brokers and their respective associated persons and floor brokers. The Commodity Broker and the Managing Owner are members of the NFA (the Fund is not required to become a member of
the NFA).

The CFTC has no authority to regulate trading on foreign commodity exchanges and markets.

Employees

The Fund has
no employees.

Investment and Trading Related Risks

The Value of the Shares Relates Directly to the Value of the Futures Contracts and Other Assets Held by the Fund and Fluctuations in the Price of These Assets Could Materially Adversely Affect an
Investment in the Funds Shares.

The Shares are designed to reflect as closely as possible the changes, whether
positive or negative, in the level of the Index, over time, through its investment in the DX Contracts. The value of the Shares relates directly to the changes in market value over time, whether positive or negative, of the DX Contracts, less the
liabilities (including estimated accrued but unpaid expenses) of the Fund. The price of the DX Contracts may fluctuate widely. Several factors may affect the price of the Index Currencies, and in turn, the DX Contracts owned by the Fund, including,
but not limited to:



| |  |  | National debt levels and trade deficits, including changes in balances of payments and trade;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | Domestic and foreign inflation rates and investors expectations concerning inflation rates;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Domestic and foreign interest rates and investors expectations concerning interest rates;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Currency exchange rates;
| | - |  | ------------------------



| |  |  | Investment and trading activities of mutual funds, hedge funds and currency funds;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | Global or regional political, economic or financial events and situations;
| | - |  | --------------------------------------------------------------------------



| |  |  | Supply and demand changes which influence the foreign exchange rates of various currencies;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | Monetary policies of governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment
in a country or on investment by residents of a country in other countries), trade restrictions, currency devaluations and revaluations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Governmental intervention in the currency market, directly and by regulation, in order to influence currency prices; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | Expectations among market participants that a currencys value soon will change.
| | - |  | --------------------------------------------------------------------------------

Net Asset Value May Not Always Correspond to Market Price and, as a Result, Baskets May be Created or Redeemed at a Value that Differs from the
Market Price of the Shares.

The net asset value per Share will change as fluctuations occur in the market value of its
portfolio. Investors should be aware that the public trading price of a Basket may be different from the net asset value of a Basket (i.e., 200,000 Shares may trade at a premium over, or a discount to, net asset value of a Basket) and similarly the
public trading price per Share may be different from its net asset value per Share. Consequently, an Authorized Participant may be able to create or redeem a Basket at a discount or a premium to the public trading price per Share. This price
difference may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares are closely related, but not identical, to the same forces influencing the prices of the Index Currencies trading
individually or in the aggregate at any point in time. Investors also should note that the size of the Fund in terms of total assets held may change substantially over time and from time-to-time as Baskets are created and redeemed.

Authorized Participants or their clients or customers may have an opportunity to realize a riskless profit if they can purchase a
Creation Basket at a discount to the public trading price of the Shares or can redeem a Redemption Basket at a premium over the public trading price of the Shares. The Managing Owner expects that the exploitation of such arbitrage opportunities by
Authorized Participants and their clients and customers will tend to cause the public trading price to track net asset value per Share closely over time.

The value of a Share may be influenced by non-concurrent trading hours between the NYSE Arca and ICE Futures U.S., which is the futures exchange on which DX Contracts are traded. While the Shares trade on
the NYSE Arca from 9:30 a.m. to 4:00 p.m. Eastern Standard Time, DX Contracts are traded for 22 consecutive hours on ICE Futures U.S. from 8:00 p.m. Eastern Standard Time to 6:00 p.m. Eastern Standard Time on the next business day. As a result,
during the time when the ICE Futures U.S. is open and the NYSE Arca is closed, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the price of the Shares and the net asset
value of the Shares.

The Funds Performance May Not Always Replicate Exactly the Changes in the Level of the Index.

It is possible that the Funds performance may not fully replicate the changes in the level of the Index due to
disruptions in the markets for the Index Currencies, DX Contracts, or due to other extraordinary circumstances.

##### Table of Contents

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, and in turn, increasing
the Funds tracking error with respect to the Index.

If speculative position limits are applied to the DX Contracts and
the Fund approaches or reached such speculative position limits, the Fund may potentially increase its tracking error with respect to the Index. 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:



| |  |  | invest in a different month DX Contract other than the specific DX Contract that was originally required by the Index, or
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | invest in another futures contract substantially similar to the DX Contracts, if available, or
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | invest in the futures contracts referencing the Index Currencies, or
| | - |  | --------------------------------------------------------------------



| |  |  | invest in a forward agreement, swap, or other OTC derivative referencing the Index Currencies,
| | - |  | ----------------------------------------------------------------------------------------------

if, in the commercially reasonable judgment of the Managing Owner, such above instruments tend to exhibit trading prices that correlate
with the DX Contract. Any of the above substitute instruments may potentially increase tracking error between the Fund and the Index.

Furthermore, the Fund is not able to replicate exactly the changes in the level of the Index because the total return is reduced by expenses and transaction costs, including those incurred in connection
with its trading activities, and increased by interest income from its holdings of short-term high quality fixed income securities. Tracking the Index requires trading of the Funds portfolio with a view to tracking the Index over time and is
dependent upon the skills of the Managing Owner and its trading principals, among other factors.

The Fund is Not Actively Managed and
Will Track the Index During Periods in Which the Index Is Flat or Declining as well as when the Index Is Rising.

The
Fund is not actively managed by traditional methods. For example, if the DX Contracts owned by the Fund are declining in value, the Fund will not close out such positions, except in connection with a change in the composition or weighting of the
Index. The Managing Owner will seek to cause the net asset value to track the Index during periods in which the Index is flat or declining as well as when the Index is rising.

Investors Who Invest Only in the Fund May Not be Able to Profit if the Market Value of the DX Contracts Moves Against Such Investment.

The Fund is expected to rise as a result of any downward price movement in DX Contracts.

If the price of the DX Contracts decreases, the Fund will profit and the PowerShares DB US Dollar Bullish Fund (the Bullish
Fund) will suffer a loss. If the price of the DX Contracts increases, the Fund will suffer a loss and the Bullish Fund will profit. Therefore, the investment experience of investors who plan to invest in either the Fund or the Bullish Fund
will depend upon selection of the appropriate fund in light of the price movements of the DX Contracts. Such selection may become unprofitable in the future if the price of the DX Contracts changes direction.

Certain investors who decide to invest in both the Shares and Bullish Fund Shares may, nevertheless, suffer losses if the investors
investment mix between the Shares and the Bullish Fund Shares is biased in one direction and the market price of the DX Contracts moves in the opposite direction. Additionally, investors should not invest in equal amounts in both the Fund and the
Bullish Fund simultaneously. The net effect of such an investment will be the income from the underlying 3-month U.S. Treasury bills, less fees and expenses.

##### Table of Contents

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

The Shares are listed for trading on the NYSE Arca under the market symbol UDN. Trading in Shares may be
halted due to market conditions or, in light of NYSE Arca rules and procedures, for reasons that, in the view of the NYSE Arca, make trading in Shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market
volatility pursuant to circuit breaker rules that require trading to be halted for a specified period based on a specified market decline. There can be no assurance that the requirements necessary to maintain the listing of the Shares
will continue to be met or will remain unchanged. The Fund will be terminated if the Shares are delisted.

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

Although the Shares are listed and traded on the NYSE Arca, there can be no guarantee that an active trading market for the Shares will
develop or be maintained. If you need to sell your Shares at a time when no active market for them exists, the price you receive for your Shares, assuming that you are able to sell them, likely will be lower than that you would receive if an active
market did exist.

The Shares Are a New Securities Product and Their Value Could Decrease if Unanticipated Operational or Trading
Problems Arise.

The mechanisms and procedures governing the creation, redemption and offering of the Shares have been
developed specifically for this securities product. Consequently, there may be unanticipated problems or issues with respect to the mechanics of the operations of the Fund and the trading of the Shares that could have a material adverse effect on an
investment in the Shares. In addition, although the Fund is not actively managed by traditional methods, to the extent that unanticipated operational or trading problems or issues arise, the Managing Owners past experience and
qualifications may not be suitable for solving these problems or issues.

As the Managing Owner and its Principals have Been Operating
Investment Vehicles like the Fund Since January 2006, their Experience may be Inadequate or Unsuitable to Manage the Fund.

The Managing Owner was formed to be the managing owner of investment vehicles such as the Fund and has been managing such investment vehicles since January 2006. The past performances of the Managing
Owners management of other commodity pools are no indication of its ability to manage investment vehicles such as the Fund. If the experience of the Managing Owner and its principals is not adequate or suitable to manage investment vehicles
such as the Fund, the operations of the Fund may be adversely affected.

You May Not Rely on Past Performance or Index Results in
Deciding Whether to Buy Shares.

Although past performance is not necessarily indicative of future results, the
Funds performance history might (or might not) provide you with more information on which to evaluate an investment in the Fund. Likewise, the Index history might (or might not) be indicative of future Index results, or of the future
performance of the Fund. Therefore, you will have to make your decision to invest in the Fund without relying on the Funds past performance history or the Indexs closing level history.

Fewer Representative Index Currencies May Result In Greater Index Volatility.

The changes in market value over time, whether positive or negative, of DX Contracts is linked to the USDX®. The USDX® is comprised of only six Index Currencies. Accordingly, the USDX® is concentrated in terms of the number of currencies represented. You should be aware that other currency indexes are more diversified in terms of the number of
currencies included. Concentration in fewer currencies may result in a greater degree of volatility in the
USDX®, and in turn, the changes in market value of the underlying DX Contracts, under specific market conditions
and over time.

Short Selling Theoretically Exposes the Fund to Unlimited Losses.

Investors may invest in either or both of the Fund and the Bullish Fund, the second series established by the Trust.

The Bullish Fund establishes long positions on DX Contracts. The price of these DX Contracts is linked to the USDX®. The Bullish Fund will profit if the USDX® rises (i.e., the value of the U.S. dollar rises relative to the Index Currencies) and the Bullish Fund will suffer loss if the USDX® falls (i.e., the value of the U.S. dollar falls relative to the Index Currencies). Because the value of the U.S.
dollar relative to the Index Currencies cannot fall below zero, the Bullish Funds exposure to loss is limited to the notional value of the DX Contracts at the time of establishment.

##### Table of Contents

By contrast, the Fund establishes short positions on DX Contracts. The
price of these DX Contracts is linked to the USDX®. The Fund will profit if the USDX® falls (i.e., the value of the U.S. dollar falls relative to the Index Currencies) and the Fund will suffer loss if
the USDX® rises (i.e., the value of the U.S. dollar rises relative to the Index Currencies). Because the value
of the USDX® could, in theory, rise infinitely, a short position in DX Contracts exposes the Fund to
theoretically unlimited liability.

The Funds losses could result in the total loss of your investment. Because
liability due to losses will be segregated to either the Bullish Fund or the Fund, as applicable, losses to investors in the Fund will not subject investors in the Bullish Fund to such exposure.

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

Although past Index levels are not necessarily indicative of future Index
levels, the Index has experienced unusually long peak-to-valley drawdown periods.

As of December 31, 2010, the closing
level of the Index experienced a peak-to-valley drawdown of (36.82)% during the period from June 1995  January 2002.

Because it is expected that the Funds performance will track the changes in the closing levels of its Index, the Fund would suffer
a continuous drawdown during the period that an Index suffers such a drawdown period, and in turn, the value of your Shares will also suffer.

Price Volatility May Possibly Cause the Total Loss of Your Investment.

Futures contracts have a high degree of price variability and are subject to occasional rapid and substantial changes. Consequently, you
could lose all or substantially all of your investment in the Fund.

The following table* reflects various measures of
volatility** of the Long Index and the Short Index, each as calculated on an excess return basis:

|** | Volatility, for these purposes means the following:
|-- | ---------------------------------------------------

Daily Volatility: The relative rate at which the price of the Index moves up and down, found by calculating the annualized standard deviation of the daily change in price.

Monthly Return Volatility: The relative rate at which the price of the Index moves up and down, found by calculating the annualized
standard deviation of the monthly change in price.

Average Annual Volatility: The average of yearly volatilities for a
given sample period. The yearly volatility is the relative rate at which the price of the Index moves up and down, found by calculating the annualized standard deviation of the daily change in price for each business day in the given year.

Fees and
Commissions are Charged Regardless of Profitability and May Result in Depletion of Assets.

The
Fund is indirectly subject to the fees and expenses described herein which are payable irrespective of profitability. Such fees and expenses include asset-based fees of 0.75% per annum.3Additional charges include brokerage fees of approximately 0.05% per annum in the aggregate and selling
commissions. For the avoidance of doubt, selling commissions are not included in the Funds breakeven calculation. The Fund is expected to earn interest income at an annual rate of 0.09% per annum, based upon the yield on 3-month U.S.
Treasury bills as of February 22, 2011. Because the Funds current interest income does not exceed its fees and expenses, the Fund will need to have a positive performance that exceeds the difference between the Funds interest income
and its fees and expenses in order to break even. If the aggregate of the Funds performance and interest income do not exceed the Funds fees and expenses described herein, then the expenses of the Fund could, over time, result in losses
to your investment therein. You may never achieve profits, significant or otherwise.



|3 | From February 15, 2007 through January 3, 2010, the Management Fee payable by the Fund was 0.50% per annum of the daily net asset value
of the Fund. Effective January 4, 2010, the Management Fee payable by the Fund was increased from 0.50% to 0.75% per annum of the daily net asset value of the Fund.

You Cannot Be Assured of the Managing Owners Continued Services, Which Discontinuance May Be
Detrimental to the Fund.

You cannot be assured that the Managing Owner will be willing or able to continue to service
the Fund for any length of time. If the Managing Owner discontinues its activities on behalf of the Fund, the Fund may be adversely affected.

Possible Illiquid Markets May Exacerbate Losses.

Futures positions cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A
market disruption, such as when foreign governments may take or be subject to political actions which disrupt the markets in their currency or major exports, can also make it difficult to liquidate a position.

There can be no assurance that market illiquidity will not cause losses for the Fund. The large size of the positions which the Fund may
acquire increases the risk of illiquidity by both making its positions more difficult to liquidate and increasing the losses incurred while trying to do so. Any type of disruption or illiquidity will be exacerbated due to the fact that the Fund only
invests in the DX Contract.

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

The Fund may, in its discretion, suspend the right of redemption or postpone
the redemption settlement date, (1) for any period during which an emergency exists as a result of which the redemption distribution is not reasonably practicable, or (2) for such other period as the Managing Owner determines to be
necessary for the protection of the Shareholders of the Fund. In addition, the Fund will reject a redemption order if the order is not in proper form as described in the participant agreement among the Authorized Participant, the Managing Owner and
the Managing Owner in its capacity as managing owner of the Fund or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. Any such postponement, suspension or rejection could adversely affect a redeeming Authorized
Participant. For example, the resulting delay may adversely affect the value of the Authorized Participants redemption proceeds if the net asset value of the Fund declines during the period of delay. The Fund disclaims any liability for any
loss or damage that may result from any such suspension or postponement.

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

Futures trading is a
risk transfer economic activity. For every gain there is an equal and offsetting loss rather than an opportunity to participate over time in general economic growth. Unlike most alternative investments, an investment in Shares does not involve
acquiring any asset with intrinsic value. Overall stock and bond prices could rise significantly and the economy as a whole prosper while Shares trade unprofitably.

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

Historically, currency futures returns have tended to exhibit low to negative correlation with the returns of
other assets such as stocks and bonds. Although currency futures trading can provide a diversification benefit to investor portfolios because of its low to negative correlation with other financial assets, the fact that the Index is not 100%
negatively correlated with financial assets such as stocks and bonds means that the Fund cannot be expected to be automatically profitable during unfavorable periods for the stock or bond market, or vice-versa. If the Shares perform in a manner that
correlates with the general financial markets or do not perform successfully, you will obtain no diversification benefits by investing in the Shares and the Shares may produce no gains to offset your losses from other investments.

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

The Fund is not registered as an investment company under the Investment Company Act of 1940, and is not
required to register under such Act. Consequently, Shareholders do not have the regulatory protections provided to the investors in registered and regulated investment companies.

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

The Fund is subject to actual and potential conflicts of interest involving the Managing Owner, various commodity futures brokers and Authorized Participants. The Managing Owner and its principals, all of
whom are engaged in other investment activities,



14



---

##### Table of Contents

are not required to devote substantially all of their time to the business of the Fund, which also presents the potential for numerous conflicts of interest with the Fund. As a result of these
and other relationships, parties involved with the Fund have a financial incentive to act in a manner other than in the best interests of the Fund and the Shareholders. The Managing Owner has not established any formal procedure to resolve conflicts
of interest. Consequently, investors are dependent on the good faith of the respective parties subject to such conflicts to resolve them equitably. Although the Managing Owner attempts to monitor these conflicts, it is extremely difficult, if not
impossible, for the Managing Owner to ensure that these conflicts do not, in fact, result in adverse consequences to the Shareholders.

The Fund may be subject to certain conflicts with respect to the Commodity Broker, including, but not limited to, conflicts that result from receiving greater amounts of compensation from other clients,
or purchasing opposite or competing positions on behalf of third party accounts traded through the Commodity Broker.

Tax Related Risks

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

Shareholders of the Fund will be subject to U.S. federal income taxation and, in some
cases, state, local, or foreign income taxation on their allocable share of the Funds taxable income, whether or not they receive cash distributions from the Fund. Shareholders of the Fund may not receive cash distributions equal to their
share of the Funds taxable income or even the tax liability that results from such income.

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

U.S. federal income tax rules applicable to partnerships are complex and often difficult to apply to publicly traded partnerships. The Fund will apply certain assumptions and conventions in an attempt to
comply with applicable rules and to report items of income, gain, loss and deduction to the Funds Shareholders in a manner that reflects the Shareholders beneficial interest in such tax items, but these assumptions and conventions may
not be in compliance with all aspects of the applicable tax requirements. It is possible that the IRS will successfully assert that the conventions and assumptions used by the Fund do not satisfy the technical requirements of the Code and/or
Treasury Regulations and could require that items of income, gain, loss and deduction be adjusted or reallocated in a manner that adversely affects one or more Shareholders.

The Current Treatment of Long Term Capital Gains Under Current U.S. Federal Income Tax Law May Be Adversely Affected, Changed or Repealed in the Future.

Under current law, long term capital gains are taxed to non-corporate investors at reduced U.S. federal income tax rates. This tax
treatment may be adversely affected, changed or repealed by future changes in, or the expiration of, tax laws at any time.

PROSPECTIVE
INVESTORS ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISERS AND COUNSEL WITH RESPECT TO THE POSSIBLE TAX CONSEQUENCES TO THEM OF AN INVESTMENT IN THE SHARES; SUCH TAX CONSEQUENCES MAY DIFFER WITH RESPECT TO DIFFERENT INVESTORS.

Other Risks

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

The CEAct requires a clearing broker to segregate all funds received from customers from such brokers
proprietary assets. If the Commodity Broker fails to do so, the assets of the Fund might not be fully protected in the event of the Commodity Brokers bankruptcy. Furthermore, in the event of the Commodity Brokers bankruptcy, Shares could
be limited to recovering either a pro rata share of all available funds segregated on behalf of the Commodity Brokers combined customer accounts or the Shares may not recover any assets at all, even though certain property specifically
traceable to the Fund was held by the Commodity Broker. The Commodity Broker may, from time-to-time, have been the subject of certain regulatory and private causes of action.

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

The Effect Of Market Disruptions, Governmental Intervention And The Dodd-Frank Wall Street Reform And Consumer Protection Act Are Unpredictable And
May Have An Adverse Effect On The Value Of Your Shares.

##### Table of Contents

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

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

In response to the recent financial crises, the Obama Administration and the U.S. Congress proposed sweeping reform of
the U.S. financial regulatory system. After over a year of debate, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Reform Act, became law in July 2010. The Reform Act seeks to regulate markets, market participants and financial
instruments that previously have been unregulated and substantially alters the regulation of many other markets, market participants and financial instruments. Because many provisions of the Reform Act require rulemaking by the applicable regulators
before becoming fully effective and the Reform Act mandates multiple agency reports and studies (which could result in additional legislative or regulatory action), it is difficult to predict the impact of the Reform Act on the Fund, the Managing
Owner, and the markets in which the Fund may invest, the Net Asset Value of the Fund or the market price of the Shares. The Reform Act could result in the Funds investment strategy becoming non-viable or non-economic to implement. The Reform
Act and regulations adopted pursuant to the Reform Act could have a material adverse impact on the profit potential of the Fund.

Lack
of Independent Advisers Representing Investors.

The Managing Owner has consulted with counsel, accountants and other
advisers regarding the formation and operation of the Fund. No counsel has been appointed to represent you in connection with the offering of the Shares. Accordingly, you should consult your own legal, tax and financial advisers regarding the
desirability of an investment in the Shares.

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

The Managing Owner may withdraw from the Fund upon 120 days notice, which would cause the Fund to terminate
unless a substitute managing owner were obtained. Owners of 50% of the Shares of the Fund have the power to terminate the Fund. If it is so exercised, investors who may wish to continue to invest in a vehicle that tracks the Index through a fund
vehicle will have to find another vehicle, and may not be able to find another vehicle that offers the same features as the Fund. Such detrimental developments could cause you to liquidate your investments and upset the overall maturity and timing
of your investment portfolio. If the registrations with the CFTC or memberships in the NFA of the Managing Owner or the Commodity Broker were revoked or suspended, such entity would no longer be able to provide services to the Fund.

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

As interests in separate series of a Delaware statutory trust, the Shares have none of the statutory rights normally associated with the
ownership of shares of a corporation (including, for example, the right to bring oppression or derivative actions). In addition, the Shares have limited voting and distribution rights (for example, Shareholders do not have
the right to elect directors and the Fund is not required to pay regular distributions, although the Fund may pay distributions at the discretion of the Managing Owner).

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

The Fund constitutes a relatively new, and thus initially untested, type of investment vehicle. It competes with other financial vehicles, including other commodity pools, hedge funds, traditional debt
and equity securities issued by companies and foreign governments, other securities backed by or linked to currencies, and direct investments in the underlying currencies or currencies futures contracts. Market and financial conditions, and other
conditions beyond the Managing Owners control, may make it more attractive to invest in other financial vehicles or to invest in such currencies directly, which could limit the market for the Shares and reduce the liquidity of the Shares.

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

While the Managing Owner believes that all intellectual property
rights needed to operate the Fund are either owned by or licensed to the Managing Owner or have been obtained, third parties may allege or assert ownership of intellectual property rights which may be related to the design, structure and operations
of the Fund. To the extent any claims of such ownership are brought or any proceedings are instituted to assert such claims, the negotiation, litigation or settlement of such claims, or the ultimate disposition of such claims in a court of law if a
suit is brought, may adversely affect the Fund and an investment in the Shares, for example, resulting in expenses or damages or the termination of the Fund.

Because the Price of DX Contracts Is Primarily Influenced by Short-Term Interest Rate Differentials, You May Sell Your Shares at a Time When the DX Contracts Are Being Traded at a Discount, and
Therefore Receive an Amount that Would be Lower than if the DX Contracts Were Trading at a Premium.

The price of DX
Contracts responds directly to short-term interest rate differentials. For example, if interest rates in the U.S. are broadly higher than international interest rates, then DX Contracts will trade at a discount to the spot index. If U.S. rates are
lower, DX Contracts will trade at a premium to the spot index. This relationship also holds for long-dated futures versus nearby futures. Because interest rates move up and down, DX Contracts may trade at a premium some of the time and at a discount
at other times. In turn, if you sell your Shares during a period when the DX Contracts are trading at a discount, you may receive less than you may have received if you sold your Shares during a period when the DX Contracts are trading at a premium.

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

Under the Agreement, the Trustee and the Managing Owner have the right to be indemnified for any liability or expense
either incurs without negligence or misconduct. That means the Managing Owner may require the assets of the Fund to be sold in order to cover losses or liability suffered by it or by the Trustee. Any sale of that kind would reduce the net asset
value of the Fund and the value of the Shares.

The Net Asset Value Calculation of the Fund May Be Overstated or Understated Due to the
Valuation Method Employed When a Settlement Price is Not Available on the Date of Net Asset Value Calculation.

Calculating the net asset value of the Fund includes, in part, any unrealized profits or losses on open foreign exchange futures
contracts. Under normal circumstances, the net asset value of the Fund reflects the settlement price of open foreign currency futures contracts on the date when the net asset value is being calculated. However, if a foreign currency futures contract
traded on an exchange (both U.S. and, to the extent it becomes applicable, non-U.S. exchanges) could not be liquidated on such day (due to the operation of daily limits or other rules of the exchange or otherwise), the settlement price on the most
recent day on which the position could have been liquidated will be the basis for determining the market value of such position for such day. In such a situation, there is a risk that the calculation of the net asset value of the Fund on such day
will not accurately reflect the realizable market value of such foreign currency futures contract. For example, daily limits are generally triggered in the event of a significant change in market price of a foreign currency futures contract.
Therefore, as a result of the daily limit, the current settlement price is unavailable. Because the settlement price on the most recent day on which the position could have been liquidated would be used in lieu of the actual settlement price on the
date of determination, there is a risk that the resulting calculation of the net asset value of the Fund could be under or overstated, perhaps to a significant degree. Although the DX Contracts that the Fund will invest in are not currently subject
to daily limits, the terms and conditions of these contracts may change in the future, and thus, may subject the Fund to the above-described risks.

Exchange Rates on the Index Currencies Could be Volatile and Could Materially and Adversely Affect the Performance of the Shares.

Foreign exchange rates are influenced by national debt levels and trade deficits, domestic and foreign inflation rates and investors
expectations concerning inflation rates, domestic and foreign interest rates and investors expectations concerning interest rates, currency exchange rates, investment and trading activities of mutual funds, hedge funds and currency funds; and
global or regional political, economic or financial events and situations. Additionally, foreign exchange rates on the Index Currencies may also be influenced by changing supply and demand for a particular Index Currency, monetary policies of
governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment in a country or on investment by residents of a country in other countries), changes in balances of payments and
trade, trade restrictions, currency devaluations and revaluations. Also, governments from time-to-time intervene in the currency markets, directly and by regulation, in order to influence prices directly. Additionally, expectations among market
participants that a currencys value soon will change may also affect exchange rates on the Index Currencies, and in turn, both the Index and the DX Contracts. These events and actions are unpredictable. The resulting volatility in the exchange
rates on the underlying Index Currencies may materially and adversely affect the market value of the DX Contracts, which would then negatively impact the value of your Shares.

Substantial Sales of Index Currencies by the Official Sector Could Adversely Affect an Investment in
the Shares.

The official sector consists of central banks, other governmental agencies and multi-lateral institutions
that buy, sell and hold certain Index Currencies as part of their reserve assets. The official sector holds a significant amount of Index Currencies that can be mobilized in the open market. In the event that future economic, political or social
conditions or pressures require members of the official sector to sell their Index Currencies simultaneously or in an uncoordinated manner, the demand for Index Currencies might not be sufficient to accommodate the sudden increase in the supply of
certain Index Currencies to the market. Consequently, the price of an Index Currency may appreciate, which may materially and adversely affect the market value of the DX Contract, which would then negatively impact the Shares.

Although the Shares are Limited Liability Investments, Certain Circumstances such as Bankruptcy of the Fund or Indemnification of the Fund by the
Shareholders will Increase the Shareholders Liability.

The Shares are limited liability investments; investors
may not lose more than the amount that they invest plus any profits recognized on their investment. However, Shareholders could be required, as a matter of bankruptcy law, to return to the estate of the Fund any distribution they received at a time
when the Fund was in fact insolvent or in violation of its Trust Agreement. In addition, although the Managing Owner is not aware of this provision ever having been invoked in the case of any public futures fund, Shareholders agree in the Trust
Agreement that they will indemnify the Fund for any harm suffered by it as a result of:



| |  |  | Shareholders actions unrelated to the business of the Fund, or

| |  |  | Taxes imposed on the Shares by the states or municipalities in which such investors reside.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

This information should be read in conjunction with the financial statements and notes included in Item 8 of Part II of this
Annual Report (the Report). The discussion and analysis which follows may contain trend analysis and other forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 which reflect our current
views with respect to future events and financial results. 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 Bearish Funds 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.

Overview/Introduction

Prior to the close of business on December 31, 2010, the Fund invested substantially all of its assets in the DB US Dollar Index
Bearish Master Fund (the Master Fund), a series of the DB US Dollar Index Master Trust (the Master Trust). After the determination of the net asset value of the Master Fund on December 31, 2010, the Master Fund
transferred and distributed all of its assets and liabilities and terminated. Effective January 1, 2011, the reorganized Fund will perform all of the necessary functions in order to continue normal Fund operation. Accordingly, the collapse of
the master-feeder structure will have no effect on the operations or processes of the Fund. All reference to historical results of the Fund include results of the Master Fund where the context requires.

The Fund establishes short 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 Short US Dollar Index
(USDX®) Futures IndexExcess Return (the Short 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, of short 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 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.

The USDX® mark is a registered service mark owned by ICE Futures U.S., Inc.

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:



| |  |  | invest in a different month DX Contract other than the specific DX Contract that was originally required by the Index, or
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | invest in another futures contract substantially similar to the DX Contracts, if available, or
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | invest in the futures contracts referencing the Index Currencies, or
| | - |  | --------------------------------------------------------------------



| |  |  | invest in a forward agreement, swap, or other OTC derivative referencing the Index Currencies,
| | - |  | ----------------------------------------------------------------------------------------------

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

##### Table of Contents

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 short positions in DX Contracts. In turn, the Fund seeks to track the Index by establishing short 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.

General

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

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

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

Margin Calls

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

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

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

Performance Summary

This report covers the three months ended December 31, 2010, 2009 and 2008 (herein referred to as the Three
Months Ended December 31, 2010, the Three Months Ended December 31, 2009 and the Three Months Ended December 31, 2008, respectively), the years ended December 31, 2010, 2009 and 2008 (herein referred
to as the Year Ended December 31, 2010, the Year Ended December 31, 2009 and the Year Ended December 31, 2008, 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 Short US Dollar Index (USDX®) Futures IndexTotal Return (Short 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 Short US Dollar Index
(USDX®) Futures IndexTotal Return and Underlying DX Contract Returns for the Three Months Ended
December 31, 2010, 2009 and 2008 and the Years Ended December 31, 2010, 2009 and 2008 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 Short Index-TR) and the Fund does not attempt to outperform or underperform the Index.

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 Short US Dollar Index (USDX®) Futures IndexTotal Return (the Short Index-TR). The only difference between the Index and the Short Index-TR is that the Index does not include
interest income from a hypothetical basket of fixed income securities while the Short Index-TR does include such a component. The difference between the Index and the Short 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 Short 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

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.

Critical
Accounting Policies

The Funds critical accounting policies are as follows:

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

##### Table of Contents

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. FASB fair value measurement and disclosure guidance requires a fair value hierarchy that prioritizes the inputs to valuation
techniques used to measure fair value. The objective of a fair value measurement is to determine the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the
measurement date (an exit price). The hierarchy gives the highest priority to unadjusted quoted prices for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Assets and
liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. See Note 4(c) within the financial statements in Item 8 for further information.

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

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

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

Market Risk

Trading in futures contracts involves the Fund entering into contractual commitments to sell 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.

Credit Risk

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. Also see
Item 1A.Risk FactorsFailure of Futures Commission Merchants or Commodity Brokers to Segregate Assets May Increase Losses; Despite Segregation of Assets, the Fund Remains at Risk of Significant Losses Because the Fund May Only
Receive a Pro-Rata Share of the Assets, or No Assets at All. In addition, CFTC regulations also require the Commodity Broker to hold in a secure account assets of the Fund related to foreign futures trading.

Liquidity

All of the Funds source of capital is derived from the Funds offering of Shares to Authorized Participants. Authorized Participants may then subsequently redeem such Shares. 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 future
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.

On any business day, an Authorized Participant may place an order with the Managing Owner to redeem one or more Baskets. Redemption orders must be placed by 1:00 p.m., New York time. The day on which the
Managing Owner receives a valid redemption order is the redemption order date. Redemption orders are irrevocable. The redemption procedures allow Authorized Participants to redeem Baskets. Individual Shareholders may not redeem directly from the
Fund. By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through DTCs book-entry system to the Fund no later than noon, New York time, on the business day immediately following the redemption
order date. By placing a redemption order, and prior to receipt of the redemption proceeds, an Authorized Participants DTC account is charged the non-refundable transaction fee due for the redemption order.

Cash Flows

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

Operating Activities

Net cash flow provided by (used for) operating activities was $134.4 million, $(166.6) million and $(37.8) million for the Years Ended
December 31, 2010, 2009 and 2008, 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 Year Ended December 31, 2010, $697.8 million was paid to purchase United States Treasury Obligations and $850.0 million
was received from sales and maturing contracts. During the Year Ended December 31, 2009, $1,166.6 million was paid to purchase United States Treasury Obligations and $974.0 million was received from sales and maturing contracts. During the Year
Ended December 31, 2008, $386.0 million was paid to purchase United States Treasury Obligations and $360.0 million was received from sales and maturing contracts. Unrealized appreciation on United States Treasury Obligations and futures
increased by $9.7 million, decreased by $12.0 million and increased by $5.0 million during the Years Ended December 31, 2010, 2009 and 2008, respectively.

Financing Activities

The Funds net cash flow provided by (used for)
financing activities was $(160.6) million, $133.0 million and $100.9 million during the Years Ended December 31, 2010, 2009 and 2008, respectively. This included $123.4 million, $348.6 million and $261.3 million from the sale of Shares to
Authorized Participants during the Years Ended December 31, 2010, 2009 and 2008, respectively.

Results of Operations

FOR THE THREE MONTHS ENDED DECEMBER 31, 2010, 2009 AND 2008, AND THE YEARS ENDED DECEMBER 31, 2010, 2009 AND 2008

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
Short US Dollar Index (USDX®) Futures IndexExcess Return (the Short 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 UDN), (ii) the Funds NAV (as reflected by the graph UDNNV), and (iii) the closing levels of the Index (as
reflected by the graph USDDNX). 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 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S 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 HEREIN, 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.

For the Three Months Ended December 31, 2008, the net asset value of each Share decreased 3.54% from $27.13 per Share to $26.17 per Share. Appreciation in price of the DX contracts during the Three
Months Ended December 31, 2008 contributed to a 3.11% decrease in the level of the Short Index-TR. On December 30, 2008, the Fund made a $0.15 per Share distribution to Shareholders of record as of December 17, 2008. Therefore, the
total return on a net asset value basis, for the Fund, including the above noted distribution, was -2.99%.

Net loss for the
Three Months Ended December 31, 2008 was $1.5 million, resulting from $0.1 million of interest income, net realized loss of $7.2 million, net unrealized gain of $5.7 million and operating expenses of $0.1 million.

Off-Balance Sheet Arrangements and Contractual Obligations

In the normal course of its business, the Fund is 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.

|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

INTRODUCTION

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.

Standard of Materiality

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

QUANTIFYING THE FUNDS TRADING VALUE AT RISK

Quantitative Forward-Looking Statements

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

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

THE FUNDS TRADING VALUE AT RISK

The Fund computed 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 December 31, 2010.

NON-TRADING RISK



33



---

##### Table of Contents

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

QUALITATIVE DISCLOSURES
REGARDING PRIMARY TRADING RISK EXPOSURES

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

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



| |  |  | National debt levels and trade deficits, including changes in balances of payments and trade;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | Domestic and foreign inflation rates and investors expectations concerning inflation rates;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Domestic and foreign interest rates and investors expectations concerning interest rates;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Currency exchange rates;
| | - |  | ------------------------



| |  |  | Investment and trading activities of mutual funds, hedge funds and currency funds;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | Global or regional political, economic or financial events and situations;
| | - |  | --------------------------------------------------------------------------



| |  |  | Supply and demand changes which influence the foreign exchange rates of various currencies;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | Monetary policies of governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment
in a country or on investment by residents of a country in other countries), trade restrictions, currency devaluations and revaluations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Governmental intervention in the currency market, directly and by regulation, in order to influence currency prices; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | Expectations among market participants that a currencys value soon will change.
| | - |  | --------------------------------------------------------------------------------

QUALITATIVE DISCLOSURES REGARDING NON-TRADING RISK EXPOSURE

General

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

QUALITATIVE DISCLOSURES REGARDING MEANS OF MANAGING RISK EXPOSURE

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

Report of Management on Internal Control

Over Financial Reporting

Management of DB Commodity Services LLC, as managing owner (the Managing Owner) of PowerShares DB US Dollar Index Bearish Fund (the Fund), is responsible for establishing and
maintaining adequate internal control over financial reporting, as defined under Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, as amended (the Exchange Act). Internal control over financial reporting is a process
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over
financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Fund; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that the Funds receipts and expenditures are being made only in
accordance with appropriate authorizations of management; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Funds assets that could have a material effect
on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent
or detect misstatements, errors or fraud. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

We, Hans Ephraimson, Chief Executive Officer, and Michael Gilligan, Principal
Financial Officer, of the Managing Owner, assessed the effectiveness of the Funds internal control over financial reporting as of December 31, 2010. In making this assessment, we used the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in Internal ControlIntegrated Framework. The assessment included an evaluation of the design of the Funds internal control over financial reporting and testing of the
operational effectiveness of its internal control over financial reporting. Based on our assessment and those criteria, we have concluded that the Fund maintained effective internal control over financial reporting as of December 31, 2010.

The Funds independent registered public accounting firm, KPMG LLP, has audited the Funds internal control over
financial reporting as of December 31, 2010, as stated in their report on page 37 of the Funds Annual Report on Form 10-K.

Report of Independent Registered Public Accounting Firm

The Board of Managers of DB Commodity Services LLC, and

The Shareholders of PowerShares DB US Dollar Index Bearish Fund:

We have
audited PowerShares DB US Dollar Index Bearish Funds (the Fund) internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control - Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). The Funds management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Report of Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Funds internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures
as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A
companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject
to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, PowerShares DB US Dollar Index Bearish Fund maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria
established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the statements of financial condition, including the schedules of investments, of
PowerShares DB US Dollar Index Bearish Fund as of December 31, 2010 and 2009, and the related statements of income and expenses, changes in shareholders equity, and cash flows for each of the years in the three-year period ended
December 31, 2010, and our report dated February 28, 2011 expressed an unqualified opinion on those financial statements.

statement presentation. We believe that our audits provide a reasonable basis for our opinion.

PowerShares DB US Dollar Index Bearish Fund

Notes to Financial Statements

December 31, 2010

(1) Organization

PowerShares DB US Dollar Index
Bearish Fund (the Fund; Fund may also refer to the Fund and the Master Fund, collectively, as the context requires), a separate series of PowerShares DB US Dollar Index Trust (the Trust), a Delaware statutory
trust organized in two separate series, and its subsidiary, DB US Dollar Index Bearish Master Fund (the Master Fund), a separate series of DB US Dollar Index Bearish Master Trust (the Master Trust), a Delaware statutory trust
organized in two separate series, were 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 in the Second Amended and Restated Declaration of Trust and Trust Agreement of the Trust (the
Trust Agreement).

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

The Fund offers common units of beneficial interest (the Shares) only to certain eligible financial institutions (the Authorized Participants) in one or more blocks of 200,000
Shares, called a Basket. The Fund commenced investment operations on 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).

This Report covers the
year ended December 31, 2010 (herein referred to as the Year Ended December 31, 2010), the year ended December 31, 2009 (herein referred to as the Year Ended December 31, 2009) and the year ended
December 31, 2008 (herein referred to as the Year Ended December 31, 2008).

(2) Fund Investment Overview

The Fund establishes short 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 Short US Dollar Index
(USDX®) Futures IndexExcess Return, the Short 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 short 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 employ leverage. As of December 31, 2010 and December 31, 2009, the Fund
had $151,574,112 (or 100%) and $320,022,426 (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, $3,183,089
(or 2.10%) and $6,739,908 (or 2.11%), respectively, of the Funds holdings of cash and United States Treasury Obligations are required to be deposited as margin in support of the Funds short futures positions on DX Contracts. For
additional information, please see the audited Schedule of Investments as of December 31, 2010 and 2009 for details of the Funds portfolio holdings.

(4) Summary of Significant Accounting Policies

(a) Basis of
Presentation

The financial statements of the Fund have been prepared using U.S. generally accepted accounting
principles and include the consolidated financial statements of the Fund and the Master Fund when applicable. As described in footnote 1, the Fund was originally formed as a master-feeder structure and such structure was collapsed on
December 31, 2010. The financial statements reflect consolidation of the Master Fund for all periods presented prior to December 31, 2010. Upon the initial offering of the Shares on February 15, 2007, the capital raised by the Fund
was used to purchase 100% of the common units of beneficial interest of the Master Fund (the Master Fund Limited Units) (excluding common units of beneficial interest of the Master Fund held by the Managing Owner (the Master Fund
General Units)). The Master Fund Limited Units owned by the Fund provided the Fund and its investors certain controlling rights and abilities over the Master Fund. Consequently, the financial statement balances for periods described previously
of the Master Fund have been consolidated with the Funds financial statement balances and all significant inter-company balances and transactions have been eliminated. Certain amounts in the 2008 financial statements have been reclassified to
conform to the 2009 and 2010 presentation.

(b) Use of Estimates

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

(c) Financial Instruments and Fair Value

United States Treasury Obligations and 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).

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

Basis of Fair Value Measurement



|         |  |                                                                                                                                                      
|-------- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1: |  | Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;            
|         | 
|Level 2: |  | Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly;
|         | 
|Level 3: |  | Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.                                   

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.

(d) Deposits with Broker



49



---

##### Table of Contents

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

(e) United States Treasury Obligations

The Fund records purchases and sales of United States Treasury Obligations on a trade date basis. These holdings are marked to market based on quoted market closing prices. The Fund holds United States
Treasury Obligations for deposit with the Funds Commodity Broker to meet margin requirements and for trading purposes. Interest income is recognized on an accrual basis when earned. Premiums and discounts are amortized or accreted over the
life of the United States Treasury Obligations. Included in the United States Treasury Obligations as of December 31, 2010 and 2009 were holdings of $3,183,089 and $6,739,908, respectively, which were restricted and held against initial margin
of the open futures contracts.

(f) Cash Held by Broker

The Funds arrangement with the Commodity Broker requires the Fund to meet its variation margin requirement related to the price
movements, both positive and negative, on futures contracts held by the Fund by keeping cash on deposit with the Commodity Broker. The Fund defines cash and cash equivalents to be highly liquid investments, with original maturities of three months
or less when purchased. As of December 31, 2010 the Fund had cash held by the Commodity Broker of $7,442,536. As of December 31, 2009, the Fund held cash of $33,574,291 of which $7,537,165 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 December 31, 2010 and 2009.

(g) Income Taxes

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

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

(h) Futures
Contracts

All currency futures contracts are held and used for trading purposes. The currency futures are recorded on
a trade date basis and open contracts are recorded in the statement of financial condition at fair value on the last business day of the period, which represents market value for those currency futures for which market quotes are readily available.
However, when market closing prices are not available, the Managing Owner may value an asset of the Fund pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. Realized gains (losses) and changes in
unrealized appreciation (depreciation) on open positions are determined on a specific identification basis and recognized in the statement of income and expenses in the period in which the contract is closed or the changes occur, respectively. As of
December 31, 2010 and 2009, the futures contracts held by the Fund were in a net unrealized appreciation position of $2,155,588 and a net unrealized depreciation position of $7,537,165, respectively.

(i) Management Fee

The Fund pays the Managing Owner a management fee (the Management Fee), monthly in arrears, in an amount equal to 0.75% per annum of the daily net asset value of the Fund. The Management
Fee is paid in consideration of the Managing Owners currency futures trading advisory services. Effective January 4, 2010, the Management Fee payable by the Fund was increased from 0.50% to 0.75% per annum of the daily net asset
value of the Fund.

(j) Brokerage Commissions and Fees

The Fund incurs all brokerage commissions, including applicable exchange fees, NFA fees, give-up fees, pit brokerage fees and other
transaction related fees and expenses charged in connection with trading activities by the Commodity Broker. These costs are recorded as brokerage commissions and fees in the statement of income and expenses as incurred. The Commodity Brokers
brokerage commissions and trading fees are determined on a contract-by-contract basis. On average, total charges paid to the Commodity Broker were less than $10.00 per round-turn trade for the Years Ended December 31, 2010, 2009 and 2008.

(k) Routine Operational, Administrative and Other Ordinary Expenses

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

(l) Organizational and Offering Costs

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

(m) Non-Recurring and Unusual Fees and Expenses

The Fund pays all fees and expenses which are non-recurring and unusual in nature. Such expenses include legal claims and liabilities, litigation costs or indemnification or other unanticipated expenses.
Such fees and expenses, by their nature, are unpredictable in terms of timing and amount. For the Years Ended December 31, 2010, 2009 and 2008, the Fund did not incur such expenses.

(5) Fair Value Measurements

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

Assets and Liabilities Measured at
Fair Value were as follows:



|                                             |  |                   |             |  |                   |   |             |  
|-------------------------------------------- |  | ----------------- | ----------- |  | ----------------- | - | ----------- | -
|                                             |  | December 31, 2010 |             |  | December 31, 2009 |  
|United States Treasury Obligations (Level 1) |  | $                 | 141,975,988 |  |                   | $ | 293,985,300 |  
|Commodity Futures Contracts (Level 1)        |  | $                 | 2,155,588   |  |                   | $ | (7,537,165  | )

There were no Level 2 or Level 3 holdings
as of December 31, 2010 and 2009.

(6) Financial Instrument Risk

In the normal course of its business, the Fund is 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 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 market conditions, resulting in such futures contracts being less
valuable. If the markets should move against all of the futures contracts at the same time, the Fund could experience substantial losses.

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

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

(7) Share Purchases and Redemptions

(a) Purchases

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

(b) Redemptions

On any business day, an Authorized Participant may
place an order with the Managing Owner to redeem one or more Baskets. Redemption orders must be placed by 1:00 p.m., New York time. The day on which the Managing Owner receives a valid redemption order is the redemption order date. Redemption orders
are irrevocable. The redemption procedures allow Authorized Participants to redeem Baskets. Individual shareholders may not redeem directly from the Fund.

By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through The Depository Trust Companys (the DTC) book-entry system to the Fund not
later than noon, New York time, on the business day immediately following the redemption order date. By placing a redemption order, and prior to receipt of the redemption proceeds, an Authorized Participants DTC account is charged the
non-refundable transaction fee due for the redemption order.

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

The redemption proceeds due from the
Fund are delivered to the Authorized Participant at noon, New York time, on the business day immediately following the redemption order date if, by such time on such business day immediately following the redemption order date, the Funds DTC
account has been credited with the Baskets to be redeemed. If the Funds DTC account has not been credited with all of the Baskets to be redeemed by such time, the redemption proceeds are delivered to the extent of whole Baskets received. Any
remainder of the redemption proceeds are delivered on the next business day to the extent of remaining whole Baskets received if the Managing Owner receives the fee applicable to the extension of the redemption distribution date which the Managing
Owner may, from time-to-time, determine and the remaining Baskets to be redeemed are credited to the Funds DTC account by noon, New York time, on such next business day. Any further outstanding amount of the redemption order will be canceled.
The Managing Owner is also authorized to deliver the redemption proceeds notwithstanding that the Baskets to be redeemed are not credited to the Funds DTC account by noon, New York time, on the business day immediately following the redemption
order date if the Authorized Participant has collateralized its obligation to deliver the Baskets through DTCs book-entry system on such terms as the Managing Owner may from time-to-time agree upon.

(8) Profit and Loss Allocations and Distributions

Pursuant to the Trust Agreement, income and expenses are allocated pro rata to the Managing Owner as holder of the General Shares and 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.

(9) Commitments and Contingencies

The Managing Owner, either in its own capacity or in its capacity as the Managing Owner and on behalf of the Fund, has entered into
various service agreements that contain a variety of representations, or provide indemnification provisions related to certain risks service providers undertake in performing services which are in the best interests of the Fund. As of
December 31, 2010 and 2009 no claims had been received by the Fund and it was therefore not possible to estimate the Funds potential future exposure under such indemnification provisions.

(10) Net Asset Value and Financial Highlights

The Fund is presenting the following net asset value and financial highlights related to investment performance for a Share outstanding for the Years Ended December 31, 2010, 2009 and 2008. The net
investment income and total expense ratios are calculated using average net asset value. The net asset value presentation is calculated using daily Shares outstanding. The 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.

|ITEM 9A. | CONTROLS AND PROCEDURES
|-------- | -----------------------

For purposes of this Item 9A, all references to the Fund shall be read to specifically include the Fund and 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 Bullish Fund, each a series of the Trust.

Evaluation of Disclosure Controls and Procedures

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

Changes in Internal Control Over Financial Reporting

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

Managements Annual Report on Internal Control Over Financial Reporting

Management of the Managing Owner is responsible for establishing and maintaining adequate internal control over financial reporting, as
defined under Rules 13a-15(f) and 15d-15(f) of the Exchange Act, for the Fund. Hans Ephraimson, the Chief Executive
