March 31, 2007

PowerShares DB Silver 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 formed on August 3, 2006, and its subsidiary, DB Silver 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 and 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 to each Fund in exchange for 40 General Shares of each 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 (the “Trust Agreement”).

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 January 3, 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. In the period ended March 31, 2007, there were no additional Limited Shares issued or redeemed.

The accompanying consolidated financial statements are unaudited, but in the opinion of management, all adjustments (which include normal recurring adjustments) considered necessary to present fairly the consolidated financial statements have been made. Certain information and footnote disclosure normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles may have been condensed or omitted. The Fund’s Prospectus should be read in conjunction with these interim consolidated financial statements. Interim period results are not necessarily indicative of results for a full-year period.

This report covers the Period from January 3, 2007 (commencement of investment operations) to March 31, 2007 (herein referred to as “Period Ended March 31, 2007”). The Fund commenced trading on the American Stock Exchange (the “Amex”) on January 5, 2007.

The Master Fund invests with a view to tracking the changes, whether positive or negative, in level of the Deutsche Bank Liquid Commodity Index–Optimum Yield Silver Excess Return™ (DBLCI-OY SI ER™) 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 Index is intended to reflect the change in market value of the silver sector. The single commodity comprising the Index, or the Index Commodity, is silver. The Master Fund holds United States Treasury obligations and other high credit quality short-term fixed income securities for deposit with the Master Fund’s commodities brokers as margin and for investment.

DBLCI™ and Deutsche Bank Liquid Commodity Index™ are trademarks of Deutsche Bank AG London (the “Index Sponsor”). Trade Mark applications in the United States are pending with respect to both the Trust and aspects of the Index. Any use of these marks must be with the consent of or under license from the Index Sponsor. The Fund, Master Fund and the Managing Owner have been licensed to use DBLCI™ and Deutsche Bank Liquid Commodity Index™. The Index Sponsor is an affiliate of the Fund, the Master Fund and the Managing Owner.

The Managing Owner

The Managing Owner serves the Fund and Master Fund as commodity pool operator, commodity trading advisor and managing owner, and is an indirect wholly-owned subsidiary of Deutsche Bank AG.

The Commodity Broker

Deutsche Bank Securities Inc., a Delaware corporation, serves as the Master Fund’s clearing broker (the “Commodity Broker”). The Commodity Broker is an indirect wholly-owned subsidiary of Deutsche Bank AG. In its capacity as clearing broker, the Commodity Broker will execute and clear each of the Master Fund’s futures transactions and will perform certain administrative services for the Master Fund. The Commodity Broker is an affiliate of the Managing Owner.

The consolidated financial statements of the Fund have been prepared using U.S. generally accepted accounting principles, and they include the financial statement balances of the Fund and the Master Fund. Upon the initial offering of the Limited 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 (“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 January 3, 2007 (commencement of investment operations), and all significant inter-company balances and transactions have been eliminated.

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.

The Fund defines cash and cash equivalents to be highly liquid investments, with original maturities of three months or less when purchased. There were no cash equivalents held by the Fund as of March 31, 2007.

The Fund records United States Treasury obligations on a trade date basis at fair value based on quoted market closing prices. The Fund holds United States Treasury obligations for deposit with the Master Fund’s commodity brokers as margin and for trading purposes. Included in the United States Treasury obligations is $1,795,500 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.

The Fund and the Master Fund are classified as a grantor trust and a partnership, respectively, 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.

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.

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 commodity futures trading advisory services.

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. On average, total charges paid to the Commodity Broker were approximately $7.00 per round-turn trade during the period ended March 31, 2007, although the Commodity Broker’s brokerage commissions and trading fees are determined on a contract-by-contract basis. Brokerage commissions and fees have approximated 0.04%, on an annual basis, of the net asset value of the Master Fund during the period ended March 31, 2007.

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.

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 period ended March 31, 2007, the Fund and the Master Fund did not incur such expenses.

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 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.

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 Amex or the last to close of the exchanges on which the Master Fund’s futures contracts are traded, whichever is later, on the date that a valid order to create a Basket is accepted by the Fund.

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. Instead, individual shareholders may only redeem Limited Shares in integral multiples of 200,000 and only through an Authorized Participant.

By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through The Depositary Trust Corporation’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 Amex or the last to close of the exchanges on which the Master Fund’s future contracts 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.

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

Table of Contents

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.

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 Shares of the Fund after the commencement of the Master Fund’s trading operations also will be paid by the Managing Owner.

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 Fund and the Master Fund. While the Fund’s and the Master Fund’s exposure under such indemnification provisions cannot be estimated, until a claim arises, 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 is presenting the following net asset value and financial highlights related to investment performance and operations for a Limited Share outstanding for the period from January 3, 2007 (commencement of investment operations) to March 31, 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.

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 Silver Excess Return™ (DBLCI-OY SI 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 Limited 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 on the single commodity comprising the Index, or the Index Commodity. The single Index Commodity is silver. 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 sponsor of the Index, or the Index Sponsor, is Deutsche Bank AG London. DBLCI™ and Deutsche Bank Liquid Commodity Index™ are trade marks of Deutsche Bank AG and are the subject of Community Trade Mark Nos. 3055043 and 3054996. Trade Mark applications in the United States are pending with respect to both the Fund and the Index. Deutsche Bank AG London is an affiliate of the Fund, the Master Fund and the Managing Owner.

Under the Trust Agreements of the Trust and the Master Trust, Wilmington Trust Company, the Trustee of the Fund and the Master Fund, 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, 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 Period from January 3, 2007 (commencement of investment operations) to March 31, 2007 (herein referred to as “Period Ended March 31, 2007”). The Fund commenced trading on the American Stock Exchange (the “Amex”) on January 5, 2007.

Table of Contents

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 is intended to reflect the change in market value of the Index Commodity. In turn, the Index is intended to reflect the silver sector. The Deutsche Bank Liquid Commodity Index-Optimum Yield Silver Total Return™, or DBLCI-OY SI 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 SI TR™ and Underlying Index Commodity Returns for the Period ended March 31, 2007” below provides an overview of the changes in the closing levels of DBLCI-OY SI 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 SI TR™) and the Fund does not attempt to outperform or underperform the Index. The Index employs the optimum yield rolls 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 SI TR™ and Underlying Index Commodity Returns for the Period ended March 31, 2007

In the current interest rate environment, the total return on an investment in the Fund is expected to outperform the Index and underperform the DBLCI-OY SI TR™. The only difference between the Index and the DBLCI-OY SI TR™ is that the Index does not include interest income from a hypothetical basket of fixed income securities while the DBLCI-OY SI TR™ does include such a component. The difference between the Index and the DBLCI-OY SI TR™ 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 Shares is expected closely to 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 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 DBLCI-OY SI TR™. 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 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

Table of Contents

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 are accrued at least 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 of the Fund and the Master Fund Limited Units, the net asset value per Limited Share and the net asset value per Master Fund 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 expects to hold a significant portion of its assets in futures contracts and United States Treasury Obligations, both of which will be recorded on trade date and at fair value in the consolidated financial statements, with changes in fair value reported in the consolidated statement of income and expenses. Generally, fair values are based on quoted market closing prices. 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.

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.

13

Table of Contents

Credit Risk

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

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 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 will be subject to periods of illiquidity because of market conditions, regulatory considerations and other reasons. For example, commodity exchanges may 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 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 future contracts (market risk) or the inability of counterparties to perform under the terms of the contracts (credit risk).

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.

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. Instead, individual Shareholders may only redeem Shares in integral multiples of 200,000 and only through an Authorized Participant. By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through DTC’s book-entry system to the Fund not later than 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.

Results of Operations

FOR THE PERIOD JANUARY 3, 2007 (COMMENCEMENT OF INVESTMENT OPERATIONS) TO MARCH 31, 2007 (REFERRED TO HEREIN AS “PERIOD ENDED MARCH 31, 2007”)

The Fund was launched on January 3, 2007 at $25.00 per share and listed for trading on the Amex on January 5, 2007.

The Fund and the Master Fund seek to track changes in the closing levels of the Deutsche Bank Liquid Commodity Index–Optimum Yield Silver Excess Return™ (DBLCI-OY SI 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 table illustrates changes in (i) the price of the Limited Shares (as reflected by the graph “DBS”), (ii) the Fund’s NAV (as reflected by the graph “DBSNAV”), and (iii) the closing levels of the Index (as reflected by the graph “DBSLIX”). 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.

COMPARISON OF DBS, DBSNAV AND DBSLIX FOR THE PERIOD ENDED MARCH 31, 2007

NEITHER THE PAST PERFORMANCE OF THE FUND NOR THE PRIOR INDEX LEVELS AND CHANGES, POSITIVE OR NEGATIVE, SHOULD BE TAKEN AS AN INDICATION OF THE FUND’S FUTURE PERFORMANCE.

Deutsche Bank Liquid Commodity Index–Optimum Yield Silver Excess Return™ is an index and does not reflect (i) actual trading and (ii) any fees or expenses.

WHILE THE FUND’S OBJECTIVE IS NOT TO GENERATE PROFIT THROUGH ACTIVE PORTFOLIO MANAGEMENT, BUT IS TO TRACK THE INDEX, BECAUSE THE INDEX WAS ESTABLISHED IN JUNE 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.

Table of Contents

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 MAY 2006, THE INDEX CLOSING LEVELS REFLECT THE APPLICATION OF THE INDEX’S METHODOLOGY, AND SELECTION OF INDEX COMMODITIES, IN HINDSIGHT.

NO HYPOTHETICAL RECORD CAN COMPLETELY ACCOUNT FOR THE IMPACT OF FINANCIAL RISK IN ACTUAL TRADING. FOR EXAMPLE, THERE ARE NUMEROUS FACTORS RELATED TO THE COMMODITIES MARKETS IN GENERAL OR TO THE IMPLEMENTATION OF THE FUND’S EFFORTS TO TRACK THE INDEX OVER TIME WHICH CANNOT BE, AND HAVE NOT BEEN, ACCOUNTED FOR IN THE PREPARATION OF THE INDEX INFORMATION SET FORTH ON THE FOLLOWING PAGES, ALL OF WHICH CAN ADVERSELY AFFECT ACTUAL PERFORMANCE RESULTS FOR THE FUND. FURTHERMORE, THE INDEX INFORMATION DOES NOT INVOLVE FINANCIAL RISK OR ACCOUNT FOR THE IMPACT OF FEES AND COSTS ASSOCIATED WITH THE FUND.

THE MANAGING OWNER 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.

FOR THE PERIOD ENDED MARCH 31, 2007

Fund Limited Share Price Performance

For the period ended March 31, 2007, Limited Shares increased 5.64% from $25.00 per share to $26.41 per share. Limited Shares traded from a low of $24.17 per share (-3.32%) on January 5, 2007 to a high of $28.96 per share (+15.84%) on February 26, 2007. Total return for the Fund, on a market value basis was 5.64% for the period ended March 31, 2007.

For the period ended March 31, 2007, the net asset value of each Limited Share increased 5.44% from $25.00 per share to $26.36 per share. Total return on a net asset value basis, for the Fund, was 5.44% for the period ended March 31, 2007.

Net income for the period ended March 31, 2007 was $1.4 million, resulting from $0.3 million of interest income and realized and unrealized gains of $1.1 million.

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.

INTRODUCTION

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

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

Value at Risk 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.

QUANTITATIVE DISCLOSURES REGARDING MARKET RISK

Information regarding quantitative information about market risk (e.g., Value at Risk) is not required pursuant to Item 305(a)(1)(iii)(B)(2) of Regulation S-K.

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 was the primary trading risk exposure of the Fund as of March 31, 2007 by Index Commodity:

Silver

The price of silver is volatile and is affected by numerous factors. The largest industrial users of silver (e.g., photographic, jewelry, and electronic industries) may influence its price. A change in economic conditions, such as a recession, can adversely affect industries which are dependent upon the use of silver. In turn, such a negative economic impact may decrease demand for silver, and, consequently, its price. Worldwide speculation and hedging activity by silver producers may also impact its price.

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

Disclosure controls and procedures.

Under the supervision and with the participation of the management of the Managing Owner, including its chief executive officer and 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) of the Securities Exchange Act of 1934). Based upon that evaluation, the chief executive officer and principal financial officer concluded that the Fund’s disclosure controls and procedures with respect to the Fund were effective as of the end of the period covered by this quarterly report.

Internal control over financial reporting.

There has been no change in internal control over financial reporting (as defined in the Securities Exchange Act of 1934 Rules 13a-15(f) and 15d-15(f)) that occurred during our last fiscal quarter that has materially affected or is reasonably likely to materially affect, the Fund’s internal control over financial reporting.
