This report must be preceded or accompanied by a prospectus. To obtain a summary prospectus, if available, or prospectus for any of our funds, refer to the Account Management Resources information provided in the back of this booklet. We advise you to consider the fund's objectives, risks, charges and expenses carefully before investing. The summary prospectus and prospectus contain this and other important information about the fund. Please read the prospectus carefully before you invest.

An investment in this fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or by any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Advisor to enter into support agreements or take other actions to maintain the fund's $1.00 share price. The credit quality of the fund's holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the fund's share price. The fund's share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. The actions of a few large investors of the fund may have a significant adverse effect on the price of the fund. See the prospectus for specific details regarding the fund's risk profile.

Information About Your Fund's Expenses

As an investor of the Fund, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and account maintenance fees, which are not shown in this section. The following tables are intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. In the most recent six-month period, the Fund limited these expenses; had it not done so, expenses would have been higher. The example in the table is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period (January 1, 2010 to June 30, 2010) .

The tables illustrate your Fund's expenses in two ways:

• Actual Fund Return. This helps you estimate the actual dollar amount of ongoing expenses (but not transaction costs) paid on a $1,000 investment in the Fund using the Fund's actual return during the period. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the "Expenses Paid per $1,000" line under the share class you hold.

• Hypothetical 5% Fund Return. This helps you to compare your Fund's ongoing expenses (but not transaction costs) with those of other mutual funds using the Fund's actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical fund return may be found in the shareholder reports of other mutual funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expense of owning different funds. If these transaction costs had been included, your costs would have been higher.

Notes to Financial Statements (Unaudited)

A. Organization and Significant Accounting Policies

DWS Money Market Series (the "Fund") is a diversified investment portfolio of DWS Money Market Trust (the "Trust"), which is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company organized as a Massachusetts business trust.

The Fund, a feeder fund, seeks to achieve its investment objective by investing all of its investable assets in a master portfolio, the Cash Management Portfolio (the "Portfolio''), an open-end management investment company registered under the 1940 Act and organized as a New York Trust advised by Deutsche Investment Management Americas Inc. ("DIMA" or the "Advisor''), an indirect, wholly owned subsidiary of Deutsche Bank AG. A master/feeder fund structure is one in which a fund (a "feeder fund"), instead of investing directly in a portfolio of securities, invests most or all of its investment assets in a separate registered investment company (the "master fund") with substantially the same investment objective and policies as the feeder fund. Such a structure permits the pooling of assets of two or more feeder funds, preserving separate identities or distribution channels at the feeder fund level. At June 30, 2010, the Fund owned approximately 72% of the Portfolio.

The Fund's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates. Actual results could differ from those estimates. The policies described below are followed consistently by the Fund in the preparation of its financial statements. The financial statements of the Portfolio, including the Investment Portfolio, are contained elsewhere in this report and should be read in conjunction with the Fund's financial statements.

Security Valuation. The Fund records its investment in the Portfolio at value, which reflects its proportionate interest in the net assets of the Portfolio. Valuation of the securities held by the Portfolio is discussed in the notes to the Portfolio's financial statements included elsewhere in this report.

Disclosure about the classification of fair value measurements is included in a table following the Portfolio's Investment Portfolio.

Federal Income Taxes. The Fund's policy is to comply with the requirements of the Internal Revenue Code, as amended, which are applicable to regulated investment companies and to distribute all of its taxable income to its shareholders.

At December 31, 2009, the Fund had a net tax basis capital loss carryforward of approximately $582,000, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized December 31, 2016 (the expiration date), whichever occurs first.

The Fund has reviewed the tax positions for the open tax years as of December 31, 2009 and has determined that no provision for income tax is required in the Fund's financial statements. The Fund's federal tax returns for the prior three fiscal periods/years remain open subject to examination by the Internal Revenue Service.

Distribution of Income and Gains. Net investment income of the Fund is declared as a daily dividend and is distributed to shareholders monthly. The Fund may take into account capital gains and losses in its daily dividend declarations. The Fund may also make additional distributions for tax purposes if necessary.

Permanent book and tax differences relating to shareholder distributions will result in reclassifications to paid in capital. Temporary book and tax differences will reverse in a subsequent period. There were no significant book to tax differences for the Fund.

The tax character of current year distributions will be determined at the end of the current fiscal year.

Contingencies. In the normal course of business, the Fund may enter into contracts with service providers that contain general indemnification clauses. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet been made. However, based on experience, the Fund expects the risk of loss to be remote.

Other. The Fund receives a daily allocation of the Portfolio's net investment income and net realized gains and losses in proportion to its investment in the Portfolio. Expenses directly attributed to a fund are charged to that fund, while expenses which are attributable to the Trust are allocated among the funds in the Trust on the basis of relative net assets.

B. Fees and Transactions with Affiliates

Management Agreement. Under the Investment Management Agreement with Deutsche Investment Management Americas Inc. ("DIMA" or the "Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG, the Advisor serves as the Investment Manager to the Fund. The Advisor receives a management fee from the Portfolio pursuant to the master/feeder structure listed above in Note A.

Pursuant to the Investment Management Agreement, the Fund pays no management fee to the Advisor so long as the Fund is a feeder fund that invests substantially all of its assets in the Portfolio. In the event the Board of Trustees determines it is in the best interest of the Fund to withdraw its investment from the Portfolio, the Advisor may become responsible for directly managing the assets of the Fund under the Investment Management Agreement. In such event, the Fund would pay the Advisor a management fee as follows:

First $1.5 billion of the Fund's average daily net assets	.1500%
Next $1.75 billion of such net assets	.1500%
Next $1.75 billion of such net assets	.1350%
Over $5 billion of such net assets	.1200%

Administration Fee. Pursuant to an Administrative Services Agreement, DIMA provides most administrative services to the Fund. For all services provided under the Administrative Services Agreement, the Fund pays the Advisor an annual fee ("Administration Fee") of 0.10% of the Fund's average daily net assets, computed and accrued daily and payable monthly.

For the period from January 1, 2010 through July 29, 2010, DIMA has contractually agreed to waive its fees and/or reimburse certain operating expenses of the Fund, including expenses of the Portfolio, to the extent necessary to maintain the operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) at 0.15%.

Effective from July 30, 2010 through September 30, 2010, DIMA has contractually agreed to waive its fees and/or reimburse certain operating expenses of the Fund, including expenses of the Portfolio, to the extent necessary to maintain the operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) at 0.18%.

Accordingly, for the six months ended June 30, 2010, the Administration Fee was $12,998,549, all of which was waived.

In addition, for the six months ended June 30, 2010, the Advisor reimbursed the Fund $536,226 of other expenses.

Service Provider Fees. DWS Investments Service Company ("DISC"), an affiliate of the Advisor, is the transfer agent, dividend-paying agent and shareholder service agent of the Fund. Pursuant to a sub-transfer agency agreement between DISC and DST Systems. Inc. ("DST"), DISC has delegated certain transfer agent, dividend-paying agent and shareholder service agent functions to DST. DISC compensates DST out of the shareholder servicing fee it receives from the Fund. For the six months ended June 30, 2010, the amounts charged to the Fund by DISC aggregated $722,272, all of which was waived.

Typesetting and Filing Service Fees. Under an agreement with DIMA, DIMA is compensated for providing typesetting and certain regulatory filing services to the Fund. For the six months ended June 30, 2010, the amount charged to the Fund by DIMA included in the Statement of Operations under "reports to shareholders" aggregated $11,641, of which $10,337 is unpaid.

Trustees' Fees and Expenses. The Fund paid each Trustee not affiliated with the Advisor retainer fees plus specified amounts for various committee services and for the Board Chairperson.

Fair Value Measurements

Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds and credit risk). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Securities held by a money market fund are reflected as Level 2 because the securities are valued at amortized cost (which approximates fair value) and, accordingly, the inputs used to determine value are not quoted prices in an active market.

The following is a summary of the inputs used as of June 30, 2010 in valuing the Fund's investments. For information on the Fund's policy regarding the valuation of investments, please refer to the Security Valuation section of Note A in the accompanying Notes to Financial Statements.

Notes to Financial Statements (Unaudited)

A. Organization and Significant Accounting Policies

Cash Management Portfolio (the "Portfolio'') is registered under the Investment Company Act of 1940, as amended (the "1940 Act''), as an open-end management investment company organized as a New York business trust.

A master/feeder fund structure is one in which a fund (a "feeder fund"), instead of investing directly in a portfolio of securities, invests most or all of its investment assets in a separate registered investment company (the "master fund") with substantially the same investment objective and policies as the feeder fund. Such a structure permits the pooling of assets of two or more feeder funds, preserving separate identities or distribution channels at the feeder fund level. The Portfolio may have several feeder funds, including affiliated DWS feeder funds, with a significant ownership percentage of the Portfolio's net assets. Investment activities of these feeder funds could have a material impact on the Portfolio. As of June 30, 2010, Cash Management Fund, Cash Reserves Fund Institutional Shares, Cash Reserves Fund — Prime Series and DWS Money Market Series owned approximately 10%, 12%, 4% and 72%, respectively, of the Portfolio.

The Portfolio's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates. Actual results could differ from those estimates. The policies described below are followed consistently by the Portfolio in the preparation of its financial statements.

Security Valuation. Various inputs are used in determining the value of the Portfolios' investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, and credit risk). Level 3 includes significant unobservable inputs (including the Portfolios' own assumptions in determining the fair value of investments). The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The Portfolio values all securities utilizing the amortized cost method permitted in accordance with Rule 2a-7 under the 1940 Act and certain conditions therein. Under this method, which does not take into account unrealized capital gains or losses on securities, an instrument is initially valued at its cost and thereafter assumes a constant accretion/amortization rate to maturity of any discount or premium. Securities held by a money market portfolio are reflected as Level 2 because the securities are valued at amortized cost (which approximates fair value) and, accordingly, the inputs used to determine value are not quoted prices in an active market.

Repurchase Agreements. The Portfolio may enter into repurchase agreements with certain banks and broker/dealers whereby the Portfolio, through its custodian or sub-custodian bank, receives delivery of the underlying securities, the amount of which at the time of purchase and each subsequent business day is required to be maintained at such a level that the value is equal to at least the principal amount of the repurchase price plus accrued interest. The custodian bank holds the collateral in a separate account until the agreement matures. If the value of the securities falls below the principal amount of the repurchase agreement plus accrued interest, the financial institution deposits additional collateral by the following business day. If the financial institution either fails to deposit the required additional collateral or fails to repurchase the securities as agreed, the Portfolio has the right to sell the securities and recover any resulting loss from the financial institution. If the financial institution enters into bankruptcy, the Portfolio's claims on the collateral may be subject to legal proceedings.

Federal Income Taxes. The Portfolio is considered a Partnership under the Internal Revenue Code, as amended. Therefore, no federal income tax provision is necessary.

It is intended that the Portfolio's assets, income and distributions will be managed in such a way that an investor in the Portfolio will be able to satisfy the requirements of Subchapter M of the Code, assuming that the investor invested all of its assets in the Portfolio.

The Portfolio has reviewed the tax positions for the open tax years as of December 31, 2009 and has determined that no provision for income tax is required in the Portfolio's financial statements. The Portfolio's federal tax returns for the prior three fiscal years remain open subject to examination by the Internal Revenue Service.

Contingencies. In the normal course of business, the Portfolio may enter into contracts with service providers that contain general indemnification clauses. The Portfolio's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Portfolio that have not yet been made. However, based on experience, the Portfolio expects the risk of loss to be remote.

Other. Investment transactions are accounted for on trade date. Interest income is recorded on the accrual basis. Distributions of income and capital gains from investment companies are recorded on the ex-dividend date. Realized gains and losses from investment transactions are recorded on an identified cost basis. All discounts and premiums are accreted/amortized for both tax and financial reporting purposes.

The Portfolio makes a daily allocation of its net investment income and realized gains and losses from securities transactions to its investors in proportion to their investment in the Portfolio.

B. Fees and Transactions with Affiliates

Under the Advisor Agreement, the Portfolio pays the Advisor a monthly advisory fee based on its average daily net assets, computed and accrued daily and payable monthly, at the following annual rates:

First $3.0 billion of the Portfolio's average daily net assets	.1500%
Next $4.5 billion of such net assets	.1325%
Over $7.5 billion of such net assets	.1200%

For the period from January 1, 2010 through July 29, 2010, the Advisor has contractually agreed to reimburse certain operating expenses to the extent necessary to maintain operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) at 0.15%.

For the six months ended June 30, 2010, the Advisor waived a portion of its management fee aggregating $3,393,636 and the amount charged aggregated $18,245,773, which was equivalent to an annualized effective rate of 0.10% of the Portfolio's average daily net assets.

Administration Fee. Pursuant to an Administrative Services Agreement, DIMA provides most administrative services to the Portfolio. For all services provided under the Administrative Services Agreement, the Portfolio pays the Advisor an annual fee ("Administration Fee") of 0.03% of the Portfolio's average daily net assets, computed and accrued daily and payable monthly. For the six months ended June 30, 2010, the Administration Fee was $5,228,542, of which $711,297 is unpaid.

Trustees' Fees and Expenses. The Portfolio paid each Trustee not affiliated with the Advisor retainer fees plus specified amounts for various committee services and for the Board Chairperson.

C. Fee Reductions

The Portfolio has entered into an arrangement with its custodian whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Portfolio's custodian expenses. During the six months ended June 30, 2010, the Portfolio's custodian fee was reduced by $4,482 for custody credits earned.

D. Line of Credit

The Portfolio and other affiliated funds (the "Participants") share in a $450 million revolving credit facility provided by a syndication of banks. The Portfolio may borrow for temporary or emergency purposes, including the meeting of redemption requests that otherwise might require the untimely disposition of securities. The Participants are charged an annual commitment fee which is allocated based on net assets, among each of the Participants. Interest is calculated at a rate per annum equal to the sum of the Federal Funds Rate plus 1.25 percent plus if LIBOR exceeds the Federal Funds Rate the amount of such excess. The Portfolio may borrow up to a maximum of 33 percent of its net assets under the agreement.

E. Review for Subsequent Events

Summary of Management Fee Evaluation by Independent Fee Consultant

October 9, 2009, As Revised November 20, 2009

Pursuant to an Order entered into by Deutsche Investment Management Americas and affiliates (collectively, "DeAM") with the Attorney General of New York, I, Thomas H. Mack, have been appointed the Independent Fee Consultant for the DWS Funds (formerly the DWS Scudder Funds). My duties include preparing an annual written evaluation of the management fees DeAM charges the Funds, considering among other factors the management fees charged by other mutual fund companies for like services, management fees DeAM charges other clients for like services, DeAM's costs of supplying services under the management agreements and related profit margins, possible economies of scale if a Fund grows larger, and the nature and quality of DeAM's services, including fund performance. This report summarizes my evaluation for 2009, including my qualifications, the evaluation process for each of the DWS Funds, consideration of certain complex-level factors, and my conclusions. I served in substantially the same capacity in 2007 and 2008.

Qualifications

For more than 35 years I have served in various professional capacities within the investment management business. I have held investment analysis and advisory positions, including securities analyst, portfolio strategist and director of investment policy with a large investment firm. I have also performed business management functions, including business development, financial management and marketing research and analysis.

Since 1991, I have been an independent consultant within the asset management industry. I have provided services to over 125 client organizations, including investment managers, mutual fund boards, product distributors and related organizations. Over the past ten years I have completed a number of assignments for mutual fund boards, specifically including assisting boards with management contract renewal.

I hold a Master of Business Administration degree, with highest honors, from Harvard University and Master of Science and Bachelor of Science (highest honors) degrees from the University of California at Berkeley. I am an independent director and audit committee financial expert for two closed-end mutual funds and serve in various leadership and financial oversight capacities with non-profit organizations.

Evaluation of Fees for each DWS Fund

My work focused primarily on evaluating, fund-by-fund, the fees charged to each of the 124 publicly offered Fund portfolios in the DWS Fund family. For each Fund, I considered each of the key factors mentioned above, as well as any other relevant information. In doing so I worked closely with the Funds' Independent Directors in their annual contract renewal process, as well as in their approval of contracts for several new funds (documented separately).

In evaluating each Fund's fees, I reviewed comprehensive materials provided by or on behalf of DeAM, including expense information prepared by Lipper Analytical, comparative performance information, profitability data, manager histories, and other materials. I also accessed certain additional information from the Lipper, Strategic Insight, and Morningstar databases and drew on my industry knowledge and experience.

To facilitate evaluating this considerable body of information, I prepared for each Fund a document summarizing the key data elements in each area as well as additional analytics discussed below. This made it possible to consider each key data element in the context of the others.

In the course of contract renewal, DeAM agreed to implement a number of fee and expense adjustments requested by the Independent Directors which will favorably impact future fees and expenses, and my evaluation includes the effects of these changes.

Fees and Expenses Compared with Other Funds

The competitive fee and expense evaluation for each fund focused on two primary comparisons:

The Fund's contractual management fee (the advisory fee plus the administration fee where applicable) compared with those of a group of typically 12-15 funds in the same Lipper investment category (e.g. Large Capitalization Growth) having similar distribution arrangements and being of similar size.

The Fund's total expenses compared with a broader universe of funds from the same Lipper investment category and having similar distribution arrangements.

These two comparisons provide a view of not only the level of the fee compared with funds of similar scale but also the total expense the Fund bears for all the services it receives, in comparison with the investment choices available in the Fund's investment category and distribution channel. The principal figure-of-merit used in these comparisons was the subject Fund's percentile ranking against peers.

DeAM's Fees for Similar Services to Others

DeAM provided management fee schedules for all of its US domiciled fund and non-fund investment management accounts in any of the investment categories where there is a DWS Fund. These similar products included the other DWS Funds, non-fund pooled accounts, institutional accounts and sub-advisory accounts. Using this information, I calculated for each Fund the fee that would be charged to each similar product, at the subject Fund's asset level.

Evaluating information regarding non-fund products is difficult because there are varying levels of services required for different types of accounts, with mutual funds generally requiring considerably more regulatory and administrative types of service as well as having more frequent cash flows than other types of accounts. Also, while mutual fund fees for similar fund products can be expected to be similar, there will be some differences due to different pricing conditions in different distribution channels (e.g. retail funds versus those used in variable insurance products), differences in underlying investment processes and other factors.

Costs and Profit Margins

DeAM provided a detailed profitability analysis for each Fund. After making some adjustments so that the presentation would be more comparable to the available industry figures, I reviewed profit margins from investment management alone, from investment management plus other fund services (excluding distribution) provided to the Funds by DeAM (principally shareholder services), and DeAM profits from all sources, including distribution. A later section comments on overall profitability.

Economies of Scale

Economies of scale — an expected decline in management cost per dollar of fund assets as fund assets grow — are very rarely quantified and documented because of inherent difficulties in collecting and analyzing relevant data. However, in virtually every investment category that I reviewed, larger funds tend to have lower fees and lower total expenses than smaller funds. To see how each DWS Fund compares with this industry observation, I reviewed:

The trend in Fund assets over the last five years and the accompanying trend in total expenses. This shows if the Fund has grown and, if so, whether total expense (management fees as well as other expenses) have declined as a percent of assets.

Whether the Fund has break-points in its management fee schedule, the extent of the fee reduction built into the schedule and the asset levels where the breaks take effect, and in the case of a sub-advised Fund how the Fund's break-points compare with those of the sub-advisory fee schedule.

How the Fund's contractual fee schedule compares with trends in the industry data. To accomplish this, I constructed a chart showing how actual latest-fiscal-year contractual fees of the Fund and of other similar funds relate to average fund assets, with the subject Fund's contractual fee schedule superimposed.

Quality of Service — Performance

The quality-of-service evaluation focused on investment performance, which is the principal result of the investment management service. Each Fund's performance was reviewed over the past 1, 3, 5 and 10 years, as applicable, and compared with that of other funds in the same investment category and with a suitable market index.

In addition, I calculated and reviewed risk-adjusted returns relative to an index of similar mutual funds' returns and a suitable market index. The risk-adjusted returns analysis provides a way of determining the extent to which the Fund's return comparisons are mainly the product of investment value-added (or lack thereof) or alternatively taking considerably more or less risk than is typical in its investment category.

I also received and considered the history of portfolio manager changes for each Fund, as this provided an important context for evaluating the performance results.

Complex-Level Considerations

While this evaluation was conducted mainly at the individual fund level, there are some issues relating to the reasonableness of fees that can alternatively be considered across the whole fund complex:

I reviewed DeAM's profitability analysis for all DWS Funds, with a view toward determining if the allocation procedures used were reasonable and how profit levels compared with public data for other investment managers.

I considered whether DeAM and affiliates receive any significant ancillary or "fall-out" benefits that should be considered in interpreting the direct profitability results. These would be situations where serving as the investment manager of the Funds is beneficial to another part of the Deutsche Bank organization.

I considered how aggregated DWS Fund expenses had varied over the years, by asset class and in the context of trends in asset levels.

I reviewed the structure of the DeAM organization, trends in staffing levels, and information on compensation of investment management and other professionals compared with industry data.

Findings

Based on the process and analysis discussed above, which included reviewing a wide range of information from management and external data sources and considering among other factors the fees DeAM charges other clients, the fees charged by other fund managers, DeAM's costs and profits associated with managing the Funds, economies of scale, possible fall-out benefits, and the nature and quality of services provided, in my opinion the management fees charged the DWS Funds are reasonable.
