June 30, 2010

(1) Organization

PowerShares DB Energy 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 Multi-Sector Commodity Trust (the “Trust”), a Delaware statutory trust organized in seven separate series, and its subsidiary, DB Energy Master Fund (the “Master Fund”), a separate series of DB Multi-Sector Commodity Master Trust (the “Master Trust”), a Delaware statutory trust organized in seven 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 40 General Units of the Master Fund. The fiscal year end of the Fund is December 31^st . 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 “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 Master Fund. The Fund and the Master Fund commenced investment operations on January 3, 2007. The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC (the “NYSE Alternext”)) on January 5, 2007 and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

Financial statements of the Master Fund are presented separately. The Master Fund is wholly-owned by the Fund and the Managing Owner. Unless otherwise indicated, the notes to the consolidated financial statements apply to both the Fund and the Master Fund.

(2) Fund Investment Overview

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 Units. The Master Fund is wholly-owned by the Fund and the Managing Owner. Each Share issued by the Fund correlates with a Master Fund Unit issued by the Master Fund and held by the Fund.

The Master Fund invests with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank Liquid Commodity Index–Optimum Yield Energy Excess Return™ (“DBLCI-OY Energy ER™”, or the “Index”) plus the excess, if any, of the Master Fund’s 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 Master Fund also holds United States Treasury Obligations and other high credit quality short-term fixed income securities for deposit with the Master Fund’s commodity broker as margin.

The Index is intended to reflect the change in market value of the energy sector. The commodities comprising the Index are light sweet crude oil, heating oil, Brent crude oil, RBOB gasoline and natural gas (the “Index Commodities”). The Commodity Futures Trading Commission (the “CFTC”) and commodity exchanges impose position limits on market participants trading in certain commodities included in the Index. The Index is comprised of futures contracts on the Index Commodities that expire in a specific month and trade on a specific exchange (the “Index Contracts”). As disclosed in the Fund’s Prospectus, if the Managing Owner determines in its commercially reasonable judgment that it has become

PowerShares DB Energy Fund and Subsidiary

Notes to Unaudited Consolidated Financial Statements—(Continued)

June 30, 2010

impracticable or inefficient for any reason for the Master Fund to gain full or partial exposure to any Index Commodity by investing in a specific Index Contract, the Master Fund may invest in a futures contract referencing the particular Index Commodity other than the Index Contract or, in the alternative, invest in other futures contracts not based on the particular Index Commodity if, in the commercially reasonable judgment of the Managing Owner, such futures contracts tend to exhibit trading prices that correlate with such Index Commodity.

The Fund does not employ leverage. As of June 30, 2010 and December 31, 2009, the Fund had $335,899,566 (or 100%) and $327,999,666 (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, $22,016,338 (or 6.55%) and $18,777,165 (or 5.72%), respectively, of the Fund’s holdings of cash and United States Treasury Obligations are required to be deposited as margin in support of the Fund’s long futures positions. For additional information, please see the unaudited Consolidated Schedule of Investments as of June 30, 2010 and the audited Consolidated Schedule of Investments as of December 31, 2009 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 Shares on January 3, 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 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, and all significant inter-company balances and transactions have been eliminated. Separate financial statements of the Master Fund are presented to comply with SEC reporting requirements as the Master Fund is a separate SEC registrant.

(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, revenues and expenses 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.

Notes to Unaudited Consolidated Financial Statements—(Continued)

(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).

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 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 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. 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 June 30, 2010 and December 31, 2009 were holdings of $22,016,338 and $18,777,165, respectively, which is restricted and held against initial margin of the open futures contracts. The Fund purchased $1,000,000 notional amount of United States Treasury Obligations which was unpaid as of June 30, 2010. As a result, a payable for securities purchased is recorded for $999,621. There was no amount payable for securities purchased as of December 31, 2009.

(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 June 30, 2010 the Fund

PowerShares DB Energy Fund and Subsidiary

Notes to Unaudited Consolidated Financial Statements—(Continued)

June 30, 2009

had cash held by the Commodity Broker of $38,282,928 of which $22,016,338 was on deposit to satisfy the Fund’s negative variation margin on open futures contracts. As of December 31, 2009 the Fund had cash held by the Commodity Broker of $25,950,973. As of June 30, 2010 and December 31, 2009 there were no cash equivalents held by the Fund.

(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 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 major tax jurisdiction for the Fund and the earliest tax year subject to examination for the Fund: United States 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 appreciation (depreciation) 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 June 30, 2010 and December 31, 2009, the futures contracts held by the Fund were in a net unrealized depreciation position of $18,206,434 and a net unrealized appreciation position of $11,168,758, respectively.

(i) Management Fee

The Master 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 Master Fund. No separate Management Fee is paid by the Fund. The Management Fee is paid in consideration of the Managing Owner’s commodity 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 June 30, 2010 and 2009 and the Six Months Ended June 30, 2010 and 2009.

(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.

(l) Organizational and Offering Costs

All organizational and offering expenses of the Fund and its Master Fund are incurred and assumed by the Managing Owner. Neither the Fund nor its Master Fund are, or will be, 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.

PowerShares DB Energy Fund and Subsidiary

Notes to Unaudited Consolidated Financial Statements—(Continued)

June 30, 2010

(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 June 30, 2010 and 2009 and the Six Months Ended June 30, 2010 and 2009, 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 the fair value hierarchy discussed in Note 4(c).

Assets and Liabilities Measured at Fair Value were as follows:


	June 30, 2010			December 31, 2009
United States Treasury Obligations (Level 1)	$	315,823,072		$	290,879,935
Commodity Futures Contracts (Level 1)	$	(18,206,434	)	$	11,168,758

There were no Level 2 or Level 3 holdings as of June 30, 2010 and December 31, 2009.

(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 commodity futures, whose values are based upon an underlying asset and generally represent future commitments that have a reasonable possibility of being settled in cash or through physical delivery. The financial instruments are traded on an exchange and are standardized contracts.

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

(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 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.

PowerShares DB Energy Fund and Subsidiary

Notes to Unaudited Consolidated Financial Statements—(Continued)

June 30, 2010

Each Share issued by the Fund correlates with a Master Fund Unit issued by the Master Fund and held by the Fund. Master Fund Units may only be created 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 (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 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.

Each Share redeemed by the Fund correlates with a Master Fund Unit redeemed by the Master Fund. Master Fund Units may only be redeemed by the Fund.

(8) Profit and Loss Allocations and Distributions

The Master Fund is wholly-owned by the Fund and the Managing Owner. Each Share issued by the Fund correlates with a Master Fund Unit issued by the Master Fund and held by the Fund.

Pursuant to the Amended and Restated Declaration of Trust and Trust Agreement of the Master Trust, income and expenses are allocated pro rata to the Managing Owner as holder of the General Shares and to the Shareholders monthly based on their respective percentage interests as of the close of the last trading day of the preceding month. Any losses allocated to the Managing Owner (as the owner of the General Shares) which are in excess of the Managing Owner’s capital balance are allocated to the Shareholders in accordance with their respective interest in the 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 June 30, 2010 and 2009 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 for a Share outstanding for the Three Months Ended June 30, 2010 and 2009 and for the Six Months Ended June 30, 2010 and 2009. 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 net investment income and total expense ratios have been annualized. The total return is based on the change in net asset value of the Shares during the period. An individual investor’s return and ratios may vary based on the timing of capital transactions.

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 non-controlling interest in the Master Fund. Each 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 Shares and the Master Fund Limited Units, the net asset value per Share and the net asset value per Master Fund Limited Unit are equal.

ITEM 2.

Overview/Introduction

The Fund and the Master Fund seek to track changes, whether positive or negative, in the level of the Deutsche Bank Liquid Commodity Index–Optimum Yield Energy Excess Return™ (“DBLCI-OY Energy ER™”, 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 Shares are designed for investors who want a cost-effective and convenient way to invest in a group of commodity 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 exchange traded futures contracts that expire in a specific month and trade on a specific exchange (the “Index Contracts”) in the commodities comprising the Index (the “Index Commodities”). The Index Commodities are light sweet crude oil, heating oil, brent crude oil, RBOB gasoline and natural gas. The Index is composed of notional amounts of each of the Index Commodities. The Master Fund’s portfolio also includes United States Treasury Obligations and other high credit quality short-term fixed income securities for deposit with the Master Fund’s Commodity Broker as margin.

The notional amount of each Index Commodity included in the Index is intended to reflect the changes in market value of each such Index Commodity within the Index. The closing level of the Index is calculated on each business day by the Index Sponsor based on the closing price of the futures contracts for each of the underlying Index Commodities and the notional amounts of such Index Commodities.

The Index is rebalanced annually in November to ensure that each of the Index Commodities is weighted in the same proportion that such Index Commodities were weighted on June 4, 1990 (the “Base Date”). The following table reflects the index base weights (the “Index Base Weights”) of each Index Commodity on the Base Date:


Index Commodity		Index Base Weight (%)
Light Sweet Crude Oil		22.50
Heating Oil		22.50
Brent Crude Oil		22.50
RBOB Gasoline		22.50
Natural Gas		10.00
Closing Level on Base Date:		100.00

The following table reflects the Fund weights of each Index Commodity as of June 30, 2010:


Index Commodity		Index Base Weight (%)
Light Sweet Crude Oil		21.78
Heating Oil		22.83
Brent Crude Oil		22.78
RBOB Gasoline		23.21
Natural Gas		9.40
Closing Level as of June 30, 2010:		100.00

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

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

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

The Deutsche Bank Liquid Commodity Index–Optimum Yield Energy is calculated in USD on both an excess return (unfunded) and total return (funded) basis.

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

On the first New York business day (the “Verification Date”) of each month, each Index Commodity futures contract will be tested in order to determine whether to continue including it in the Index. If the Index Commodity futures contract requires delivery of the underlying commodity in the next month, known as the Delivery Month, a new Index Commodity futures contract will be selected for inclusion in the Index. For example, if the first New York business day is October 1, 2010, and the Delivery Month of the Index Commodity futures contract currently in such Index is November 2010, a new Index Commodity futures contract with a later Delivery Month will be selected.

For each underlying Index Commodity of the Index, the new Index Commodity futures contract selected will be the Index Commodity futures contract with the best possible “implied roll yield” based on the closing price for each eligible Index Commodity futures contract. Eligible Index Commodity futures contracts are any Index Commodity futures contracts having a Delivery Month (i) no sooner than the month after the Delivery Month of the Index Commodity futures contract currently in such Index, and (ii) no later than the 13^th month after the Verification Date. For example, if the first New York business day is October 1, 2010 and the Delivery Month of an Index Commodity futures contract currently in the Index is June 2010, the Delivery Month of an eligible new Index Commodity futures contract must be between December 2010 and October 2011. The implied roll yield is then calculated and the futures contract on the Index Commodity with the best possible implied roll yield is then selected. If two futures contracts have the same implied roll yield, the futures contract with the minimum number of months prior to the Delivery Month is selected.

After the futures contract selection, the monthly roll for each Index Commodity subject to a roll in that particular month unwinds the old futures contract and enters a position in the new futures contract. This takes place between the 2^nd and 6^th Index Business Day of the month.

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

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

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

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

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

Performance Summary

This report covers the three months ended June 30, 2010 and 2009 (hereinafter referred to as the “Three Months Ended June 30, 2010” and the “Three Months Ended June 30, 2009”, respectively) and the six months ended June 30, 2010 and 2009 (hereinafter referred to as the “Six Months Ended June 30, 2010” and the “Six Months Ended June 30, 2009”, respectively). The Fund commenced trading on the American Stock Exchange (now known as the NYSE Alternext US LLC (the “NYSE Alternext”)) on January 5, 2007, and, as of November 25, 2008, is listed on the NYSE Arca, Inc. (the “NYSE Arca”).

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

The Index is intended to reflect the change in market value of the Index Commodities. In turn, the Index is intended to reflect the energy sector. The Deutsche Bank Liquid Commodity Index-Optimum Yield Energy Total Return™ (the “DBLCI-OY Energy TR™”), consists of the Index plus 3-month United States Treasury Obligations returns. Past Index results are not necessarily indicative of future changes, positive or negative, in the Index closing levels.

The section “Summary of DBLCI-OY Energy TR™ and Underlying Index Commodity Returns for the Three Months Ended June 30, 2010 and 2009 and the Six Months Ended June 30, 2010 and 2009” below provides an overview of the changes in the closing levels of DBLCI-OY Energy TR™ by disclosing the change in market value of each underlying component Index Commodity through a “surrogate” (and analogous) index plus 3-month United States Treasury Obligations returns. Please note also that the Fund’s objective is to track the Index (not DBLCI-OY Energy TR™) and the Fund does not attempt to outperform or underperform the Index. The Index employs the optimum yield roll method with the objective of mitigating the negative effects of contango, the condition in which distant delivery prices for futures exceed spot prices, and maximizing the positive effects of backwardation, a condition opposite of contango.

Summary of DBLCI-OY Energy TR™ and Underlying Index Commodity

Returns for the Three Months Ended June 30, 2010 and 2009

and the Six Months Ended June 30, 2010 and 2009


Underlying Index	Aggregate returns for indices in the DBLCI-OY Energy TR™
Underlying Index	Three Months Ended June 30, 2010		Three Months Ended June 30, 2009		Six Months Ended June 30, 2010		Six Months Ended June 30, 2009
Light, Sweet Crude Oil (WTI) Indices	(15.15	)%	28.04	%	(12.58	)%	24.66	%
Heating Oil Indices	(10.39	)%	20.22	%	(8.17	)%	9.09	%
Brent Crude Oil Indices	(10.35	)%	29.86	%	(8.21	)%	20.42	%
RBOB Gasoline Indices	(9.98	)%	31.41	%	(7.26	)%	39.14	%
Natural Gas Indices	10.46	%	(5.97	)%	(19.67	)%	(38.70	)%
AGGREGATE RETURN	(9.79	)%	25.32	%	(10.17	)%	17.24	%

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 DBLCI-OY Energy TR™. The only difference between the Index and the DBLCI-OY Energy TR™ is that the Index does not include interest income from a hypothetical basket of fixed income securities while the DBLCI-OY Energy TR™ does include such a component. The difference between the Index and the DBLCI-OY Energy 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 DBLCI-OY Energy 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 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 commodity futures contracts, and any other credit or debit accruing to the Master Fund but unpaid or not received by the Master Fund. All open commodity futures contracts will be calculated at their then current market value, which will be based upon the settlement price for that particular commodity futures contract traded on the

applicable exchange on the date with respect to which net asset value is being determined; provided, that if a commodity futures contract could not be liquidated on such day, due to the operation of daily limits or other rules of the exchange upon which that position is traded or otherwise, the 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.

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 Shares and Master Fund Limited Units, the net asset value per 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 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. 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 1 for further information.

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.

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 commodity at a specified date and price. The market risk associated with the Master Fund’s commitments to purchase commodities 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 Shares to Authorized Participants. Authorized Participants may then subsequently redeem such Shares. The Master Fund in turn allocates its net assets to commodities trading. A significant portion of the net asset value is held in United States Treasury Obligations and cash, which is used as margin for the Master Fund’s trading in commodities. The percentage that United States Treasury Obligations bear to the total net assets will vary from period to period as the market values of the Master Fund’s commodity interests change. The balance of the net assets are held in the Master Fund’s commodity trading account. Interest earned on the Master Fund’s interest-bearing funds is paid to the Master Fund.

The Master Fund’s commodity contracts may be subject to periods of illiquidity because of market conditions, regulatory considerations or for other reasons. For example, commodity exchanges generally have the ability to limit fluctuations in certain commodity futures contract prices during a single day by regulations referred to as “daily limits.” During a single day, no trades may be executed at prices beyond the daily limit. Once the price of a particular futures contract for a particular commodity has increased or decreased by an amount equal to the daily limit, positions in the commodity can neither be taken nor liquidated unless the traders are willing to effect trades at or within the limit. Commodity futures prices have occasionally moved the daily limit for several consecutive days with little or no trading. Such market conditions could prevent the Master Fund from promptly liquidating its commodity futures positions.

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

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 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 futures contracts to match the fluctuations of the Index the Fund is tracking.

Operating Activities

Net cash flow used for operating activities was $29.5 million and $236.8 million for the Six Months Ended June 30, 2010 and 2009, respectively. This amount primarily includes net purchases and sales of United States Treasury Obligations which are held at fair value on the statement of financial condition.

During the Six Months Ended June 30, 2010, $615.6 million was paid to purchase United States Treasury Obligations and $590.8 million was received from sales and maturing contracts. During the Six Months Ended June 30, 2009, $293.7 million was paid to purchase United States Treasury Obligations and $75.8 million was received from sales and maturing contracts. Unrealized appreciation on United States Treasury Obligations and futures decreased by $29.4 million and increased by $42.9 million during the Six Months Ended June 30, 2010 and 2009, respectively.

Financing Activities

The Fund’s net cash flow provided by financing activities was $41.9 million and $215.9 million during the Six Months Ended June 30, 2010 and 2009, respectively. This included $61.6 million and $215.9 million from the sale of Shares to Authorized Participants during the Six Months Ended June 30, 2010 and 2009, respectively.

Results of Operations

FOR THE THREE MONTHS ENDED JUNE 30, 2010 AND 2009 AND THE SIX MONTHS ENDED JUNE 30, 2010 AND 2009

The Fund was launched on January 3, 2007 at $25.00 per Share. The Shares traded on the NYSE Alternext from January 5, 2007 to November 25, 2008 and have been trading on the NYSE Arca since November 25, 2008.

The Fund and the Master Fund seek to track changes in the closing levels of the Deutsche Bank Liquid Commodity Index–Optimum Yield Energy Excess Return™ (“DBLCI-OY Energy ER™”, 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 Shares (as reflected by the graph “DBE”), (ii) the Fund’s NAV (as reflected by the graph “DBENAV”), and (iii) the closing levels of the Index (as reflected by the graph “DBENIX”). Whenever the interest income earned by the Fund exceeds Fund expenses, the price of the Shares generally has exceeded the levels of the Index primarily because the Share price reflects interest income from the Master 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 or certain other similar limitations on the ability of the Fund to trade the Index Commodity. The “TR” version of the Index includes an assumed amount of interest income based on prevailing rates that is adjusted from time to time. The Fund, by contrast, invests actual money and trades actual futures contracts. As a result, the performance of the Fund involves friction, in that fees and expenses impose a drag on performance. The Fund may be subject to speculative position limits and certain other limitations on its ability to trade the Index Commodity, which may compel the Fund to trade futures or other instruments that are not the Index Commodity as proxies for the Index Commodity. The interest rate actually earned by the Fund over any period may differ from the assumed amount of interest income factored

into the “TR” version of the Index over the same period. All of these factors can contribute to discrepancies between changes in net asset value per Share and changes in the level of the Index over any period of time. 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 Index Commodity as proxies for the Index Commodity could cause changes in the net asset value per Share to outperform or underperform changes in the value of the Index over any given period, all other things being equal.

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 JULY 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 1988 THROUGH JUNE 2006, THE INDEX CLOSING LEVELS REFLECT THE APPLICATION OF THE INDEX’S METHODOLOGY, AND SELECTION OF INDEX COMMODITY, IN HINDSIGHT.

NO HYPOTHETICAL RECORD CAN COMPLETELY ACCOUNT FOR THE IMPACT OF FINANCIAL RISK IN ACTUAL TRADING. FOR EXAMPLE, THERE ARE NUMEROUS FACTORS, INCLUDING THOSE DESCRIBED UNDER ITEM 1A. “RISK FACTORS” SET FORTH IN THE FUND’S ANNUAL REPORT ON FORM 10-K/A FOR THE YEAR ENDED DECEMBER 31, 2009, RELATED TO THE COMMODITIES MARKETS IN GENERAL OR TO THE IMPLEMENTATION OF THE FUND’S EFFORTS TO TRACK THE INDEX OVER TIME WHICH CANNOT BE, AND HAVE NOT BEEN, ACCOUNTED FOR IN THE PREPARATION OF THE INDEX INFORMATION SET FORTH ON THE FOLLOWING PAGES, ALL OF WHICH CAN ADVERSELY AFFECT ACTUAL PERFORMANCE RESULTS FOR THE FUND. FURTHERMORE, THE INDEX INFORMATION DOES NOT INVOLVE FINANCIAL RISK OR ACCOUNT FOR THE IMPACT OF FEES AND COSTS ASSOCIATED WITH THE FUND.

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

FOR THE THREE MONTHS ENDED JUNE 30, 2010 COMPARED TO THE THREE MONTHS ENDED JUNE 30, 2009

Fund Share Price Performance

For the Three Months Ended June 30, 2010, the NYSE Arca market value of each Share decreased 10.20% from $25.78 per Share to $23.15 per Share.

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 commodity futures, whose values are based upon an underlying asset and generally represent future commitments which have a reasonable possibility to be settled in cash or through physical delivery. The financial instruments are traded on an exchange and are standardized contracts.

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

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

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 IN DIFFERENT MARKET SECTORS

Commencing December 31, 2009 the Fund computed VaR using the actual historical market movements of the Fund’s total assets, as opposed to the previous methodology of using the historical market movements of the underlying futures contracts in connection with the Index Commodities only. Prior to December 31, 2009, the historical market movements of the underlying futures contracts were used because the actual historical market movements of the Fund were not sufficient.

The following table indicates the trading VaR associated with the Fund’s total assets as of June 30, 2010.


Description	Total Assets		Daily Volatility		VaR* (99 Percentile)		Number of times VaR Exceeded
PowerShares DB Energy Fund	$	335,899,566	1.69	%	$	13,143,402	0

*	The VaR represents the one day downside risk, under normal market conditions, with a 99% confidence level. It is calculated using historical market moves of the Fund’s total assets and uses a one year look-back.

The following table indicates the trading VaR associated with the Fund’s total assets as of December 31, 2009.


Description	Total Assets		Daily Volatility		VaR* (99 Percentile)		Number of times VaR Exceeded
PowerShares DB Energy Fund	$	327,999,666	2.31	%	$	17,640,527	3

*	The VaR represents the one day downside risk, under normal market conditions, with a 99% confidence level. It is calculated using historical market moves of the Fund’s total assets and uses a one year look-back.

NON-TRADING RISK

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

The following were the primary trading risk exposures of the Fund as of June 30, 2010 by Index Commodity:

Light Sweet Crude Oil

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

Heating Oil

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

Brent Crude Oil

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

RBOB Gasoline

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

Natural Gas

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

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.

For purposes of this Item 4, all references to the “Fund” shall be read to specifically include the Fund and the Master Fund.

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 quarterly 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.
