PowerShares DB US Dollar Index Bullish Fund and Subsidiary

Notes to Unaudited Consolidated Financial Statements

September 30, 2008

(1) Organization

PowerShares DB US Dollar Index Bullish 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 Bullish Master Fund (the “Master Fund”), a separate series of DB US Dollar Index Bullish 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”), funded both the Fund and the Master Fund with a capital contribution of $1,000 in exchange for 40 General Shares of the Fund and the Master 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 Amended and Restated Declaration of Trust and Trust Agreement of the Trust and the Master Trust (each a “Trust Agreement” and collectively the “Trust Agreements”).

The Fund offers common units of beneficial interest (the “Limited Shares”) only to certain eligible financial institutions (“Authorized Participants”) in one or more blocks of 200,000 Limited Shares, called a Basket. The proceeds from the offering of Limited Shares are invested in the Master Fund. The Fund and the Master Fund commenced investment operations on February 15, 2007 with the initial offering of 1,000,000 Limited Shares to Deutsche Bank Securities Inc. as initial purchaser of the Fund in exchange for $25,000,000. The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC) on February 20, 2007.

This report covers the three months ended September 30, 2008 and 2007, the nine months ended September 30, 2008 and the period from February 15, 2007 (commencement of investment operations) through September 30, 2007 (hereinafter referred to as the “Period Ended September 30, 2007”).

(2) Fund Investment Overview

The Master Fund invests in futures contracts, or DX Contracts, with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank US Dollar Index (USDX^®) Futures Index – Excess Return (Long Index), the Long Index or the Index, over time. The Fund earns interest income from United States Treasury Obligations and other high credit quality short-term fixed income securities. The Index is calculated to reflect the changes in market value over time, whether positive or negative, of long positions on DX Contracts. DX Contracts are traded through the currency markets of ICE Futures U.S. (formerly known as the New York Board of Trade^®), under the symbol “DX.” The changes in market value over time, whether positive or negative, of the DX Contracts are related to the changes, whether positive or negative, in the level of the U.S. Dollar Index^®, or the USDX^®. The Index provides a general indication of the international value of the U.S. dollar relative to the six major world currencies, or Index Currencies, which comprise the USDX^® — Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.

The Fund, through its Master Fund, establishes long positions in DX Contracts with a view to tracking the changes, whether positive or negative, in the level of the Index. The performance of the Fund also is intended to reflect the excess, if any, of its Master 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 and its Master Fund.

The Fund does not employ leverage. As of September 30, 2008 and December 31, 2007, the Fund had $599,887,132 (or 100%) and $99,672,786 (or 100%) of its holdings of cash, United States Treasury Obligations and unrealized appreciation/depreciation of futures contracts on deposit with its Commodity Broker. Of this, $14,469,735 (or 2.41%) and $1,343,832 (or 1.35%) of the Fund’s holdings of cash and United States Treasury Obligations are required to be deposited as margin in support of the Fund’s long futures positions on DX Contracts. For additional information, please see the unaudited Consolidated Schedule of Investments dated September 30, 2008 and the audited Consolidated Schedule of Investments dated December 31, 2007 for a breakdown of the Fund’s portfolio holdings.

(4) Summary of Significant Accounting Policies

(a) Basis of Presentation and Consolidation

The consolidated financial statements of the Fund have been prepared using U.S. generally accepted accounting principles, and they include the consolidated financial statement balances of the Fund and the Master Fund. Upon the initial offering of the Limited 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 (“Master Fund Limited Units”) (excluding common units of beneficial interest of the Master Fund held by the Managing Owner (“Master Fund General Units”)). The Master Fund Limited Units owned by the Fund provide the Fund and its investors certain controlling rights and abilities over the Master Fund. Consequently, the financial statement balances of the Master Fund have been consolidated with the Fund’s financial statement balances beginning February 15, 2007 (commencement of investment operations), and all significant inter-company balances and transactions have been eliminated.

(b) Use of Estimates

The preparation of the consolidated 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, revenue and expense and related disclosure of contingent assets and liabilities during the reporting period of the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

(c) Financial Instruments and Fair Value

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

The Fund adopted FASB Statement No. 157, “Fair Value Measurements” (Statement 157), effective January 1, 2008. Statement 157 establishes 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

12

liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under Statement 157 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 commodity futures contracts, the Fund uses unadjusted quoted market prices in active markets. United States Treasury Obligations and commodity futures contracts are classified within Level 1 of the fair value hierarchy. The Fund does not adjust the quoted prices for United States Treasury Obligations and commodity futures contracts.

(d) Deposits with Broker

The Fund deposits cash and United States Treasury Obligations with its Commodity Broker subject to Commodity Futures Trading Commission (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 Master Fund’s Commodity Broker to meet margin requirements and for trading purposes. Included in the United States Treasury Obligations as of September 30, 2008 and December 31, 2007 are $14,469,735 and $1,343,832, respectively, which is restricted and held against initial margin of the open futures contracts. 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.

(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 held by the Commodity Broker to be highly liquid investments, with original maturities of three months or less when purchased. As of September 30, 2008 and December 31, 2007, the Fund had cash held by the Commodity Broker of $48,595,252 and $2,673,775, respectively. There were no cash equivalents held by the Fund as of September 30, 2008 and December 31, 2007.

(g) Income Taxes

The Fund and the Master Fund are classified as partnerships for U.S. federal income tax purposes. Accordingly, neither the Fund nor the Master Fund will incur U.S. federal income taxes. No provision for federal, state, and local income

13

taxes has been made in the accompanying consolidated financial statements, as investors are individually liable for income taxes, if any, on their allocable share of the Fund’s share of the Master Fund’s income, gain, loss, deductions and other items.

The following are the major tax jurisdictions for the Fund and the earliest tax year subject to examination:

Jurisdiction	Tax Year
US Federal	2007
State of New York	2007
New York City	2007
State of Florida	2007
State of Georgia	2007
State of Maine	2007
State of Oregon	2007
State of Utah	2007
State of West Virginia	2007

(h) Futures Contracts

All commodity futures contracts are held and used for trading purposes. The commodity futures are recorded on a trade date basis and open contracts are recorded in the consolidated statement of financial condition at fair value on the last business day of the period, which represents market value for those commodity futures for which market quotes are readily available. However, when market closing prices are not available, the Managing Owner may value an asset of the Master Fund pursuant to policies the Managing Owner has adopted, which are consistent with normal industry standards. Realized gains (losses) and changes in unrealized gains (losses) on open positions are determined on a specific identification basis and recognized in the consolidated statement of income and expenses in the period in which the contract is closed or the changes occur, respectively. As of September 30, 2008 and December 31, 2007, the futures contracts held by the Fund were in a net unrealized depreciation position of $4,677,530 and a net unrealized appreciation position of $428,580, respectively.

(i) Management Fee

The Master Fund currently pays the Managing Owner a management fee (“Management Fee”), monthly in arrears, in an amount equal to 0.50% per annum of the daily net asset value of the Master Fund. No separate Management Fee is paid by the Fund. The Management Fee is paid in consideration of the Managing Owner’s currency futures trading advisory services.

(j) Brokerage Commissions and Fees

The Master 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 consolidated statement of income and expenses as incurred. The Commodity Broker’s brokerage commissions and trading fees are determined on a contract-by-contract basis. On average, total charges paid to the Commodity Broker were less than $10.00 per round-turn trade for the Three Months Ended September 30, 2008 and 2007 and for the Nine Months Ended September 30, 2008 and the Period Ended September 30, 2007.

(k) Routine Operational, Administrative and Other Ordinary Expenses

The Managing Owner assumes all routine operational, administrative and other ordinary expenses of the Fund and the Master 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 consolidated statement of income and expenses of the Fund.

14

(l) Organizational and Offering Costs

All organizing and offering expenses of the Fund and its Master Fund are incurred and assumed by the Managing Owner. Expenses incurred in connection with the continuous offering of Limited Shares also will be paid by the Managing Owner.

(m) Non-Recurring and Unusual Fees and Expenses

The Master Fund pays all fees and expenses, if any, of the Fund and the Master Fund, which are non-recurring and unusual in nature. Such expenses include legal claims and liabilities, litigation costs or indemnification or other unanticipated expenses. Such fees and expenses, by their nature, are unpredictable in terms of timing and amount. For the Three Months Ended September 30, 2008 and 2007, the Fund and the Master Fund did not incur such expenses. For the Nine Months Ended September 30, 2008 and for the Period Ended September 30, 2007, the Fund and the Master 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 a fair value hierarchy in accordance with Statement 157. See Note 4(c) for discussion of the Fund’s policies regarding this hierarchy.

Assets and Liabilities Measured at Fair Value as of September 30, 2008:

United States Treasury Obligations (Level 1)	$	555,969,410
Commodity Futures Contracts (Level 1)	$	(4,677,530	)

There were no Level 2 or Level 3 holdings as of September 30, 2008.

(6) Financial Instrument Risk

In the normal course of its business, the Master 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 Master 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 Master Fund due to market changes, including fluctuations in currency prices. In entering into these futures contracts, there exists a market risk that such futures contracts may be significantly influenced by adverse market conditions, resulting in such futures contracts being less valuable. If the markets should move against all of the futures contracts at the same time, the Master 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 Master Fund’s risk of loss in the event of counterparty default is typically limited to the amounts recognized in the consolidated statement of financial condition and not represented by the futures contract or notional amounts of the instruments.

The Fund and the Master Fund have not utilized, nor do they expect to utilize in the future, special purpose entities to facilitate off-balance sheet financing arrangements and have 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

Limited 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 Limited 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 Limited Shares as of the closing time of the NYSE Alternext US LLC or the last to close of the exchanges on which the Master Fund’s assets are traded, whichever is later, on the date that a valid order to create a Basket is accepted by the Fund.

(b) Redemptions

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

By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through The Depository Trust Company’s (“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 Alternext US LLC or the last to close of the exchanges on which the Master 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.

(c) Limited Share Transactions

The Fund and the Master Fund commenced investment operations on February 15, 2007 with the initial offering of 1,000,000 Limited Shares to Deutsche Bank Securities Inc. as the initial purchaser of the Fund in exchange for $25,000,000. The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC) on February 20, 2007.

(8) Profit and Loss Allocations and Distributions

Pursuant to the Trust Agreement of the Master Trust, income and expenses are allocated pro rata to the General and Limited 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 (the owner of the General Shares) which are in excess of the Managing Owner’s capital balance are allocated to the Limited shareholders in accordance with their respective interest in the Master 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 and the Master 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 Funds. As of September 30, 2008, no claims had been received by the Fund or the Master Fund and it was therefore not possible to estimate the Fund’s and the Master 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 and operations for a Limited Share outstanding for the Three Months Ended September 30, 2008 and 2007 and for the Nine Months Ended September 30, 2008 and the Period Ended September 30, 2007. The net investment income and total expense ratios are calculated using average net asset value. The net asset value presentation is calculated using daily Limited Shares outstanding. The net investment income and total expense ratios have been annualized. The total return is based on the change in net asset value of the Limited Shares during the period. An individual investor’s return and ratios may vary based on the timing of capital transactions.

The Fund invests substantially all of its assets in the Master Fund in a master-feeder structure. The Fund holds no investment assets other than Master Fund Limited Units. The Fund is the majority Master Fund Limited Unit owner and the Managing Owner holds a minority interest in the Master Fund. Each Limited Share issued by the Fund correlates with the Master Fund Limited Unit issued by the Master Fund and held by the Fund.

Net asset value per Master Fund Limited Unit and Master Fund General Unit (collectively, “Master Fund Units”) is the net asset value of the Master Fund divided by the number of outstanding Master Fund Units. Because there is a one-to-one correlation between Limited Shares and the Master Fund Limited Units, the net asset value per Limited Share and the net asset value per Master Fund Limited Unit are equal.

(11) Recently Issued Accounting Standards

In December 2007, the Financial Accounting Standards Board released FASB Statement No. 160, Noncontrolling Interests in Consolidated Financial Statements – an amendment to ARB No. 51 (Statement 160). Statement 160 requires noncontrolling interests (previously referred to as minority interests) to be reported as a component of equity, which changes the accounting for transactions with noncontrolling interest holders. Statement 160 is effective for periods beginning on or after December 15, 2008 and earlier adoption is prohibited. Statement 160 will be applied prospectively to all noncontrolling interests including any that arose before the effective date and presentation and disclosure requirements shall be applied retrospectively for all periods presented.

On March 19, 2008, the Financial Accounting Standards Board released FASB Statement No. 161, Disclosures about Derivative Instruments and Hedging Activities (Statement 161). Statement 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The application of Statement 161 is required for fiscal years beginning after November 15, 2008 and interim periods within those fiscal years.

At this time, management is evaluating the implications of these Statements and their impact on the financial statements has not yet been determined.

Overview/Introduction

The Fund and the Master Fund seek to track changes, whether positive or negative, in the level of the Deutsche Bank US Dollar Index (USDX^®) Futures Index – Excess Return (Long Index), the Long Index or the Index, over time, plus the excess, if any, of the Master 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 and the Master Fund. The Limited 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 Fund pursues its investment objective by investing substantially all of its assets in the Master Fund. The Master Fund pursues its investment objective by investing in a portfolio of futures contracts, or DX Contracts, on the currencies comprising the Index. The Master Fund’s portfolio also includes United States Treasury Obligations and other high credit quality short-term fixed income securities. The Index is calculated to reflect the changes in market value over time, whether positive or negative, of long positions on DX Contracts. DX Contracts are traded through the currency markets of ICE Futures U.S. (formerly known as the New York Board of Trade^®), under the symbol “DX.” The changes in market value over time, whether positive or negative, of the DX Contracts are related to the changes, whether positive or negative, in the level of the U.S. Dollar Index^®, or the USDX^®. The Index provides a general indication of the international value of the U.S. dollar relative to the six major world currencies, or Index Currencies, which comprise the USDX^® — Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.

The Fund, through its Master Fund, establishes long positions in DX Contracts with a view to tracking the changes, whether positive or negative, in the level of the Index. The performance of the Fund also is intended to reflect the excess, if any, of its Master 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 such Fund and its Master Fund.

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 futures contracts, or DX Contracts, whose changes in market value over time, whether positive or negative, in turn, is tied to the U.S. Dollar Index^®, or 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 six underlying currencies of the USDX^®, or the Index Currencies. (Although the Index tracks the changes in market value over time, whether positive or negative, of the first to expire DX Contracts, the closing levels of the Index is in effect, and in part, a reflection of the changes, whether positive or negative, in the level of the underlying Index Currencies.) The Index Currencies are Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. The Index Currencies

19

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).

USDX^® is composed of notional amounts of each Index Currency. The notional amounts of the Index Currencies included in 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 a base period of 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 Index has been historically comparable in range and variability to a broad-based, multi-capitalization stock index future. The DX Contract price is sized at $1000 times the Index closing level. Thus, if the Index closing level is 100.00, the DX Contract will be valued $100,000. If the Index closing level is 112.50, each DX Contract will have a $112,500 value.

The sponsor of the Index is Deutsche Bank AG London, or the Index Sponsor.

USDX^® Composition.

The Index reflects the changes in market value over time, whether positive or negative, of 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. USDX^® is computed 24 hours a day, seven days a week based on exchange rates supplied to Reuters by some 500 banks worldwide.

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

Index Currency	Index Base Weight (%)
Euro	57.60
Japanese Yen	13.60
British Pound	11.90
Canadian Dollar	9.10
Swedish Krona	4.20
Swiss Franc	3.60
Closing Level at Inception:	100.00

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.

Index Calculation.

The Index reflects the changes in market value over time, whether positive or negative, of the first to expire DX Contract relative to the value of the dollar as of December 31, 1986, or Base Date. 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 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 each 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 each Index have been calculated using historic exchange closing price data of the DX Contract since the Base Date.

The Long Index is calculated to reflect the changes in market value over time, whether positive or negative, of long positions in the DX Contracts which expires in March, June, September and December. The use of long positions in DX Contracts in the construction of the Long Index causes the Long Index to rise as a result of any upward price movement in the DX Contracts. In turn, this appreciation in the long DX Contracts reflects the rise of the U.S. dollar relative to the underlying basket of Index Currencies which comprise the USDX^®.

Since the Base Date, the Long Index closing level has ranged on a daily basis from as high as 100.58 on January 5, 1987 to as low as 54.14 on April 22, 2008. Past Index levels are not necessarily indicative of future Index levels.

Index Rolls.

The underlying DX Contracts of the Index are rolled quarterly on the Index Roll Day, which is the Wednesday prior to the applicable IMM Date. “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 the Wednesday prior to each IMM Date as follows:

• The DX Contract that expires on the next IMM Date is sold.

• A position in the DX Contract that expires on the IMM Date following the next IMM Date is purchased.

General

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

The Index Sponsor obtains information for inclusion in, or for use in the calculation of, the Index from sources the Index Sponsor considers reliable. None of the Index Sponsor, the Managing Owner, the Trust, the Fund, the Master Trust, and the Master 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 Limited 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 Limited Shares is expected to fluctuate in relation to changes in the value of the Master Fund’s portfolio. The market price of the Limited Shares may not be identical to the net asset value per Limited Share, but these two valuations are expected to be very close.

Performance Summary

This report covers the three months ended September 30, 2008 and 2007, the nine months ended September 30, 2008 and the period from February 15, 2007 through September 30, 2007 (hereinafter referred to as the “Period Ended September 30, 2007”).

Performance of the Fund and the exchange traded Limited 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, or Index Currencies, which comprise the USDX^® — Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. The Deutsche Bank US Dollar Index (USDX^®) Futures Index – Total Return (Long Index) (Long Index-TR), consists of the Index plus 3-month United States Treasury bills returns. Past Index results are not necessarily indicative of future changes, positive or negative, in the Index closing levels.

The section “Summary of Deutsche Bank US Dollar Index (USDX^®) Futures Index – Total Return (Long Index) and Underlying DX Contract Returns for the Three Months Ended September 30, 2008 and 2007 and the Nine Months Ended September 30, 2008 and the Period Ended September 30, 2007” 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 that the Fund’s objective is to track the Index (not the Long Index-TR™) and the Fund does not attempt to outperform or underperform the Index.

Summary of Deutsche Bank US Dollar Index (USDX^®) Futures Index – Total Return (Long Index) and Underlying DX Contract Returns for the Three Months Ended September 30, 2008 and 2007 and the Nine Months Ended September 30, 2008 and the Period Ended September 30, 2007

Underlying DX Contract Returns	Total returns for the LONG INDEX-TR
	Three Months Ended September 30, 2008	Three Months Ended September 30, 2007	Nine Months Ended September 30, 2008	Period Ended September 30, 2007
DX Contract	8.76%	(3.70)%	2.83%	(3.90)%

In the current interest rate environment, the total return on an investment in the Fund is expected to outperform the Index and underperform the Deutsche Bank US Dollar Index (USDX^®) Futures Index – Total Return (the “Long Index”). The only difference between the Index and the Long Index is that the Index does not include interest income from a hypothetical basket of fixed income securities while the Long Index does include such a component. The difference between the Index and the Long Index is attributable entirely to the hypothetical interest income from this hypothetical basket of fixed income securities. The Fund’s interest income from its holdings of fixed-income securities is expected to exceed the Fund’s fees and expenses, and the amount of such excess is expected to be distributed periodically. The market price of the Limited Shares is expected to closely track the Index. The total return on an investment in the Fund over any period is the sum of the capital appreciation or depreciation of the Limited Shares over the period, plus the amount of any distributions during the period. Consequently, in the current interest rate environment, the Fund’s total return is expected to outperform the Index by the amount of the excess of its interest income over its fees and expenses but, as a result of the Fund’s fees and expenses, the total return on the Fund is expected to underperform the Long Index. If the Fund’s fees and expenses were to exceed the Fund’s interest income from its holdings of fixed income securities, the Fund would underperform the Index.

Net Asset Value

Net asset value means the total assets of the Master Fund, including, but not limited to, all futures, cash and investments less total liabilities of the Master 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 Master Fund but unpaid or not received by the Master 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

22

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 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. The Managing Owner may in its discretion (and only under extraordinary 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 Master 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 Master Fund’s brokerage account is accrued monthly. The amount of any distribution is a liability of the Master Fund from the day when the distribution is declared until it is paid.

The Fund invests substantially all of its assets in the Master Fund in a master-feeder structure. The Fund holds no investment assets other than Master Fund Limited Units. The Fund is the majority Master Fund Limited Unit owner and the Managing Owner holds a minority interest in the Master Fund. Each Limited Share issued by the Fund correlates with the Master Fund Limited Unit issued by the Master Fund and held by the Fund.

Net asset value per Master Fund Limited Unit and Master Fund General Unit (collectively, “Master Fund Units”) is the net asset value of the Master Fund divided by the number of outstanding Master Fund Units. Because there is a one-to-one correlation between Limited Shares and the Master Fund Limited Units, the net asset value per Limited Share and the net asset value per Master Fund Limited Unit are equal.

Critical Accounting Policies

The Fund’s and Master 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 consolidated financial statements and accompanying notes. Both the Fund’s and the Master Fund’s application of these policies involve judgments and actual results may differ from the estimates used.

The Master 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 consolidated financial statements, with changes in fair value reported in the consolidated statement of income and expenses.

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

In determining fair value of United States Treasury Obligations and commodity futures contracts, the Fund uses unadjusted quoted market prices in active markets. Statement 157 establishes 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 I for further information regarding Statement 157.

When market closing prices are not available, the Managing Owner may value an asset of the Master 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 consolidated statement of income and expenses in the period in which the contract is closed or the changes occur, respectively.

23

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 Master Fund entering into contractual commitments to purchase a particular currency at a specified date and price. The market risk associated with the Master Fund’s commitments to purchase currencies is limited to the gross or face amount of the contracts held.

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

The Commodity Broker, when acting as the Master 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 Master Fund all assets of the Master Fund relating to domestic futures trading and the Commodity Broker is not allowed to commingle such assets with other assets of the Commodity Broker. In addition, CFTC regulations also require the Commodity Broker to hold in a secure account assets of the Master Fund related to foreign futures trading.

Liquidity

All of the Master Fund’s source of capital is derived from the Fund through the Fund’s offering of Limited Shares to Authorized Participants. (Authorized Participants may then subsequently redeem such Limited Shares). The Master 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 Master 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 Master Fund’s currency futures change. The balance of the net assets is held in the Master Fund’s trading account. Interest earned on the Master Fund’s interest-bearing funds is paid to the Master Fund.

The Master Fund’s currency futures contracts may be subject to periods of illiquidity because of market conditions, regulatory considerations and 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 traders are willing to effect trades at or within the limit. Although the DX Contracts that the Master Fund invests in are not currently subject to daily limits, the DX Contracts held by the Master Fund could become subject to such limits in the future. Such market conditions could prevent the Master Fund from promptly liquidating its currency futures positions.

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

On any business day, an Authorized Participant may place an order with the Managing Owner to redeem one or more Baskets. Redemption orders must be placed by 10:00 a.m., New York time. The day on which the Managing Owner receives a valid redemption order is the redemption order date. Redemption orders are irrevocable. The redemption

24

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 activities of the Fund are to raise capital from Authorized Participants through the issuance of Limited Shares in the Fund. This cash is invested into the Master Fund where it 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 used for operating activities was $420.9 million and $8.3 million during the Nine Months Ended September 30, 2008 and Period Ended September 30, 2007, respectively. These amounts primarily include net purchases and sales of United States Treasury Obligations which are held at fair value on the statement of financial condition. During the Nine Months Ended September 30, 2008, $1,541.1 million was paid to purchase United States Treasury Obligations and $1,087.3 million was received from sales of maturing contracts. During the Period Ended September 30, 2007, $53.4 million was paid to purchase United States Treasury Obligations and $45.9 million was received from sales of maturing contracts. Unrealized loss on futures contracts increased by $4.4 million and by $0.2 million during the Nine Months Ended September 30, 2008 and Period Ended September 30, 2007, respectively.

Financing Activities

The Fund’s net cash flow provided by financing activities was $466.8 million and $10.1 million during the Nine Months Ended September 30, 2008 and the Period Ended September 30, 2007, respectively. This included $889.2 million and $25.0 million from the sale of Limited Shares to Authorized Participants during the Nine Months Ended September 30, 2008 and the Period Ended September 30, 2007, respectively.

Results of Operations

FOR THE THREE MONTHS ENDED SEPTEMBER 30, 2008 AND 2007, THE NINE MONTHS ENDED SEPTEMBER 30, 2008 AND FOR THE PERIOD ENDED SEPTEMBER 30, 2007

The Fund was launched on February 15, 2007 at $25.00 per share and listed for trading on the American Stock Exchange (now known as the NYSE Alternext US LLC) on February 20, 2007.

The Fund and the Master Fund seek to track changes in the closing levels of the Deutsche Bank US Dollar Index (USDX^®) Futures Index – Excess Return (Long Index), the Long Index or the Index, over time, plus the excess, if any, of the Master 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 and the Master Fund. The following graphs illustrate changes in (i) the price of the Limited Shares (as reflected by the graph “UUP”), (ii) the Fund’s NAV (as reflected by the graph “UUPNAV”), and (iii) the closing levels of the Index (as reflected by the graph “USDUPX”). The price of the Limited Shares generally has exceeded the levels of the Index primarily because the Limited Share price reflects interest income from the Master Fund’s collateral holdings whereas the Index does not consider such interest income. There can be no assurances that the price of the Limited Shares will continue to exceed the Index levels.

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 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 IN THE FUND’S ANNUAL REPORT OF FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 2007, RELATED TO THE CURRENCIES MARKETS IN GENERAL OR TO THE IMPLEMENTATION OF THE FUND’S EFFORTS TO TRACK THE INDEX OVER TIME WHICH CANNOT BE, AND HAVE NOT BEEN, ACCOUNTED FOR IN THE PREPARATION OF THE INDEX INFORMATION SET FORTH ON THE FOLLOWING PAGES, ALL OF WHICH CAN ADVERSELY AFFECT ACTUAL PERFORMANCE RESULTS FOR THE FUND. FURTHERMORE, THE INDEX INFORMATION DOES NOT INVOLVE FINANCIAL RISK OR ACCOUNT FOR THE IMPACT OF FEES AND COSTS ASSOCIATED WITH THE FUND.

THE MANAGING OWNER HAS HAD LIMITED EXPERIENCE IN TRADING ACTUAL ACCOUNTS FOR ITSELF OR FOR CLIENTS. BECAUSE THERE ARE LIMITED ACTUAL TRADING RESULTS TO COMPARE TO THE INDEX CLOSING LEVELS SET FORTH HEREIN, PROSPECTIVE INVESTORS SHOULD BE PARTICULARLY WARY OF PLACING UNDUE RELIANCE ON THE ANNUAL OR CUMULATIVE INDEX RESULTS.

Off-Balance Sheet Arrangements and Contractual Obligations

In the normal course of its business, the Master 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 Master 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 and the Master Fund have not utilized, nor do they expect to utilize in the future, special purpose entities to facilitate off-balance sheet financing arrangements and have 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

29

include indemnification provisions related to certain risks service providers undertake in performing services which are in the best interests of the Fund and the Master Fund. While the Fund’s and the Master Fund’s exposure under such indemnification provisions cannot be estimated, these general business indemnifications are not expected to have a material impact on either the Fund’s or the Master Fund’s financial position.

The Fund and Master 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 Master Fund’s net asset value. Commission payments to the Commodity Broker are on a contract-by-contract, or round-turn, basis. As such, the Managing Owner cannot anticipate the amount of payments that will be required under these arrangements for future periods as net asset values are not known until a future date. These agreements are effective for one year terms, renewable automatically for additional one year terms unless terminated. Additionally, these agreements may be terminated by either party for various reasons.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

INTRODUCTION

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

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

Value at Risk is a measure of the maximum amount which the Fund could reasonably be expected to lose in a given market sector. However, the inherent uncertainty in the markets in which the Fund trades and the recurrence in the markets traded by the Fund of market movements far exceeding expectations could result in actual trading or non-trading losses far beyond the indicated Value at Risk 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 Value at Risk or by the Fund’s attempts to manage its market risk.

Standard of Materiality

Materiality as used in this section, “Quantitative and Qualitative Disclosures About Market Risk,” is based on an assessment of reasonably possible market movements and the potential losses caused by such movements, taking into account the leverage, and multiplier features 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).

The Fund’s risk exposure in the various market sectors traded by the Fund is quantified below in terms of Value at Risk. Exchange maintenance margin requirements have been used by the Fund as the measure of its Value at Risk. Maintenance margin requirements are set by exchanges to equal or exceed 95-99% of the maximum one-day losses at fair value of any given contract incurred during the time period over which historical price fluctuations are researched for purposes of establishing margin levels. The maintenance margin levels are established by exchanges using historical price studies as well as an assessment of current market volatility and economic fundamentals to provide a probabilistic estimate of the maximum expected near-term one-day price fluctuation.

THE FUND’S TRADING VALUE AT RISK IN DIFFERENT MARKET SECTORS

The following table indicates the trading Value at Risk associated with the Fund’s open positions by market category as of September 30, 2008. There has been no material change in the trading Value at Risk information previously disclosed in the Fund’s Annual Report on Form 10-K for the year ended December 31, 2007.

Market Sector	Delivery Month	Value at Risk (VaR) $ Value*	Value at Risk (“VaR”)* % of Net Assets		Number of times VaR Exceeded
Dollar Long	December 2008	7,199,125	1.18	%	7
Aggregate/Total		7,188,029	1.18	%	7

The following table indicates the trading Value at Risk associated with the Fund’s open positions by market category as of December 31, 2007.

Market Sector	Delivery Month	Value at Risk (VaR) $ Value*		Value at Risk (“VaR”)* % of Net Assets		Number of times VaR Exceeded
Dollar Long	March 2008	$	729,982	0.73	%	7
Aggregate/Total		$	729,982	0.73	%	7

* The VaR for a contract represents the one day, downside risk, under normal market conditions, with a 99% confidence level. It is calculated using historical market moves for the contract and uses a one year look-back. The aggregate VaR for the fund represents the VaR of the Fund’s open positions across all contracts, and is less than the sum of VaRs for each individual contract due to the diversification benefit across the contracts.

NON-TRADING RISK

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

QUALITATIVE DISCLOSURES REGARDING PRIMARY TRADING RISK EXPOSURES

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

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;

31

• 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 “long” side of the market and does not employ “stop-loss” techniques.

ITEM 4. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of the management of the Managing Owner, including Kevin Rich, its Chief Executive Officer and Michael Gilligan, its Principal Financial Officer, the Fund carried out an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this quarterly report, and, based upon that evaluation, Kevin Rich, 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.
