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 share price of the fund. See the prospectus for specific details regarding the fund's risk profile.

Notes to Financial Statements (Unaudited)

A. Organization and Significant Accounting Policies

Cash Management Fund (the "Fund") is a diversified series 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 currently offers one class of shares, Institutional Shares, to investors.

The Fund is a feeder fund that seeks to achieve its investment objective by investing substantially 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, 2015, the Fund owned approximately 7% 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.

Under the Regulated Investment Company Modernization Act of 2010, net capital losses incurred post-enactment may be carried forward indefinitely, and their character is retained as short-term and/or long-term. Previously, net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

At December 31, 2014, the Fund had a net tax basis capital loss carryforward of approximately $154,000 of pre-enactment losses, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or until 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, 2014 and has determined that no provision for income tax and/or uncertain tax provisions is required in the Fund's financial statements. The Fund's federal tax returns for the prior three fiscal 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 an 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.

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, 2015 through April 30, 2016, DIMA has contractually agreed to waive its fees and/or reimburse certain operating expenses of the Fund, including expenses of the Portfolio allocated to the Fund, to the extent necessary to maintain the total annual operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) at 0.30% of the Fund's average daily net assets.

In addition, the Advisor has agreed to voluntarily waive additional expenses. The waiver may be changed or terminated at any time without notice. Under this arrangement, the Advisor waived certain expenses of the Fund.

For the six months ended June 30, 2015, the Administration Fee was $607,975, of which $252,057 was waived and $72,441 is unpaid.

Service Provider Fees. DeAWM Service Company ("DSC"), an affiliate of the Advisor, is the transfer agent, dividend-paying agent and shareholder service agent for the Fund. Pursuant to a sub-transfer agency agreement between DSC and DST Systems, Inc. ("DST"), DSC has delegated certain transfer agent, dividend-paying agent and shareholder service agent functions to DST. DSC compensates DST out of the shareholder servicing fee it receives from the Fund. For the six months ended June 30, 2015, the amount charged to the Fund by DSC aggregated $23,290, all of which was waived.

Shareholder Servicing Fee. DeAWM Distributors, Inc. ("DDI"), an affiliate of the Advisor, provides information and administrative services for a fee ("Service Fee") to shareholders at an annual rate of up to 0.25% of average daily net assets. DDI in turn has various agreements with financial services firms that provide these services and pays these fees based upon the assets of shareholder accounts the firm services. For the six months ended June 30, 2015, the Service Fee was as follows:

	Total Aggregated		Waived		Annualized Effective Rate
Cash Management Fund	$	365,047	$	365,047		.00	%

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, 2015, the amount charged to the Fund by DIMA included in the Statement of Operations under "Reports to shareholders" aggregated $9,304, of which $9,100 is unpaid.

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

C. Concentration of Ownership

From time to time, the Fund may have a concentration of several shareholder accounts holding a significant percentage of shares outstanding. Investment activities of these shareholders could have a material impact on the Fund.

At June 30, 2015, there were two shareholder accounts that each held approximately 43% and 17% of the outstanding shares of the Fund, respectively.

D. Money Market Fund Reform

In July 2014, the SEC adopted money market fund reform intended to address potential systemic risks associated with money market funds and to improve transparency for money market fund investors. The Fund is required to comply with money market reforms by the specified compliance dates, with the latest being October 14, 2016. As a result, the Fund may be required to take certain steps that will impact its structure and/or operations, which could impact the return potential of the Fund.

E. Additional Information

At a meeting on July 10, 2015, the Board approved changes to the Fund to allow the Fund to operate as a government money market fund under the amendments to Rule 2a-7 under the Investment Company Act of 1940, as amended, that were adopted in July of 2014 with final compliance dates ranging between July 2015 and October 2016. As currently structured, on the final compliance date for the Rule 2a-7 amendments, the Fund would be required to implement a floating net asset value and would be allowed, and in certain situations, required, to implement liquidity fees and redemption gates. As a government money market fund, the Fund will continue to be able to maintain a stable $1.00 net asset value. (Although this share price would not be guaranteed, and if it falls below $1.00, you would lose money.) The Fund will not be required to implement liquidity fees and redemption gates. As defined in amended Rule 2a-7, a government money market fund is a fund that invests at least 99.5% of the Fund’s total assets in cash, government securities, and/or repurchase agreements that are collateralized by these same securities.

In order for the Fund to operate as a government money market fund, the Board approved revisions to the Fund’s fundamental investment policy relating to concentration (the "Concentration Policy") such that the Fund would no longer be required to invest more than 25% of its total assets in obligations of banks and other financial institutions. If not revised, the current Concentration Policy would preclude the Fund from operating as a government money market fund. The revisions to the Concentration Policy are subject to approval by the shareholders of the Fund at a special shareholders’ meeting expected to be held during the fourth quarter of 2015. No assurance can be given that shareholder approval will be obtained for the revisions to the Concentration Policy.

The Fund is a "feeder" fund that pursues its investment objective by investing substantially all of its assets in a "master portfolio," the Portfolio, under a master-feeder structure. The Portfolio invests directly in securities and other instruments and the Fund has the same investment objective and policies as the Portfolio. Subject to the approval of a revised fundamental investment policy relating to concentration by the Portfolio’s shareholders, the Board also approved changes to permit the Portfolio to operate as a government money market fund.

If the revisions to the Concentration Policy are approved by shareholders, the Board approved other changes necessary for the Fund to operate as a government money market fund, including:

(i) A revised investment objective, as follows:

"The fund seeks maximum current income to the extent consistent with stability of principal."

(ii) The adoption of a principal investment strategy to invest at least 99.5% of the Fund’s total assets in cash, government securities, and/or repurchase agreements that are collateralized by these same securities.

(iii) Name changes, as follows:

Current Name	New Name
Cash Management Portfolio	Government Cash Management Portfolio
DWS Money Market Trust	Deutsche Money Market Trust
Cash Management Fund	Deutsche Government Cash Management Fund

(iv) A reduction in the management fee rate paid by the Portfolio to DIMA, the investment advisor to the Fund and the Portfolio. Pursuant to the master-feeder structure noted above, DIMA receives a management fee from the Portfolio.

If shareholders approve the revised fundamental investment policy relating to concentration, DIMA currently anticipates that the changes implementing the Fund’s operation as a government money market fund will take effect on or about May 2, 2016. To ensure an orderly transition to a government money market fund, DIMA anticipates that it will begin to gradually implement changes to the Portfolio beginning in the first quarter of 2016. As a result, it is expected that the Portfolio gradually will allocate a larger percentage of its assets to government securities over time until it reaches its new allocation on or about May 2, 2016. Because the yields on government securities generally may be expected to be lower than the yields on comparable non-government securities, it should be expected that the Fund's yield may decrease as more assets are invested in government securities.

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 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, 2015 to June 30, 2015).

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.

Expenses and Value of a $1,000 Investment for the six months ended June 30, 2015 (Unaudited)
Actual Fund Return*	Institutional Shares
Beginning Account Value 1/1/15	$	1,000.00
Ending Account Value 6/30/15	$	1,000.05
Expenses Paid per $1,000**	$	1.04
Hypothetical 5% Fund Return*	Institutional Shares
Beginning Account Value 1/1/15	$	1,000.00
Ending Account Value 6/30/15	$	1,023.75
Expenses Paid per $1,000**	$	1.05

* Expenses include amounts allocated proportionally from the master portfolio.

** Expenses are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181 (the number of days in the most recent six-month period), then divided by 365.

Fair Value Measurements

Various inputs are used in determining the value of the Portfolio'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 Portfolio's own assumptions in determining the fair value of investments). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Securities held by the 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.

The following is a summary of the inputs used as of June 30, 2015 in valuing the Portfolio's investments. For information on the Portfolio'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 trust.

The Portfolio is a master fund. 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 Deutsche feeder funds and unaffiliated 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, 2015, Cash Management Fund, Cash Reserves Fund Institutional, Cash Reserves Fund — Prime Series and Deutsche Money Market Series owned approximately 7%, 5%, 5% and 79%, 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 Portfolio'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 Portfolio's own assumptions in determining the fair value of investments). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Securities held by the 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.

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 the 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, under the terms of a Master Repurchase Agreement, with certain banks and broker/dealers whereby the Portfolio, through its custodian or a 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 or another designated subcustodian 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.

As of June 30, 2015, the Portfolio held repurchase agreements with a gross value of $2,878,250,000. The value of the related collateral exceeded the value of the repurchase agreements at period end. The detail of the related collateral is included in the footnotes following the Portfolio's Investment Portfolio.

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, 2014 and has determined that no provision for income tax and/or uncertain tax provisions 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. 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 an 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

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 determines the securities, instruments and other contracts relating to investments to be purchased, sold or entered into by the Portfolio.

Under the Investment Management Agreement, the Portfolio pays the Advisor a monthly management 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, 2015 through June 30, 2015, the Advisor has voluntarily agreed to waive its fees and/or reimburse certain operating expenses to the extent necessary to maintain the total annual operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) at 0.14% of the Portfolio's average daily net assets. This voluntary waiver or reimbursement may be terminated at any time at the option of the Advisor.

For the six months ended June 30, 2015, the Advisor waived a portion of its management fee aggregating $2,598,360, and the amount charged aggregated $9,688,614, which was equivalent to an annualized effective rate of 0.10%.

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, 2015, the Administration Fee was $2,890,434, of which $483,088 is unpaid.

Filing Service Fees. Under an agreement with DIMA, DIMA is compensated for providing certain regulatory filing services to the Portfolio. For the six months ended June 30, 2015, the amount charged to the Portfolio by DIMA included in the Statement of Operations under "Reports to shareholders" aggregated $681, all of which is unpaid.

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

C. Line of Credit

The Portfolio and other affiliated funds (the "Participants") share in a $400 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 the one-month 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. The Portfolio had no outstanding loans at June 30, 2015.

D. Money Market Fund Reform

In July 2014, the SEC adopted money market fund reform intended to address potential systemic risks associated with money market funds and to improve transparency for money market fund investors. The Portfolio is required to comply with money market reforms by the specified compliance dates, with the latest being October 14, 2016. As a result, the Portfolio may be required to take certain steps that will impact its structure and/or operations, which could impact the return potential of the Portfolio.

E. Additional Information

At a meeting on July 10, 2015, the Board approved changes to the Portfolio to allow the Portfolio to operate as a government money market fund under the amendments to Rule 2a-7 under the Investment Company Act of 1940, as amended, that were adopted in July of 2014 with final compliance dates ranging between July 2015 and October 2016. As currently structured, on the final compliance date for the Rule 2a-7 amendments, the Portfolio would be required to implement a floating net asset value and would be allowed, and in certain situations, required, to implement liquidity fees and redemption gates. As a government money market fund, the Portfolio will continue to utilize amortized cost to value its securities. The Portfolio will not be required to implement liquidity fees and redemption gates. As defined in amended Rule 2a-7, a government money market fund is a fund that invests at least 99.5% of the Portfolio’s total assets in cash, government securities, and/or repurchase agreements that are collateralized by these same securities.

In order for the Portfolio to operate as a government money market fund, the Board approved revisions to the Portfolio’s fundamental investment policy relating to concentration (the "Concentration Policy") such that the Portfolio would no longer be required to invest more than 25% of its total assets in obligations of banks and other financial institutions. If not revised, the current Concentration Policy would preclude the Portfolio from operating as a government money market fund. The revisions to the Concentration Policy are subject to approval by the shareholders of the Portfolio at a special shareholders’ meeting expected to be held during the fourth quarter of 2015. No assurance can be given that shareholder approval will be obtained for the revisions to the Concentration Policy.

If the revisions to the Concentration Policy are approved by shareholders, the Board approved other changes necessary for the Portfolio to operate as a government money market fund, including:

(i) A revised investment objective, as follows:

"The fund seeks maximum current income to the extent consistent with stability of principal."

(ii) The adoption of a principal investment strategy to invest at least 99.5% of the Portfolio’s total assets in cash, government securities, and/or repurchase agreements that are collateralized by these same securities.

(iii) Name changes as follows:

Current Name	New Name
Cash Management Portfolio	Government Cash Management Portfolio

(iv) A reduction in the management fee rate paid by the Portfolio to DIMA, the investment advisor to the Portfolio. Pursuant to the master-feeder structure noted above, DIMA receives a management fee from the Portfolio. The revised management fee rate schedule is set forth below:

Current Management Fee Rate Schedule				Revised Management Fee Rate Schedule
Average Daily Assets	Management Fee Rate			Average Daily Assets	Management Fee Rate
First $3 Billion		.1500	%	First $3 Billion		.1200	%
Next $4.5 Billion		.1325	%	Next $4.5 Billion		.1025	%
Over $7.5 Billion		.1200	%	Over $7.5 Billion		.0900	%

If shareholders approve the revised fundamental investment policy relating to concentration, DIMA currently anticipates that the changes implementing the Portfolio’s operation as a government money market fund will take effect on or about May 2, 2016. To ensure an orderly transition to a government money market fund, DIMA anticipates that it will begin to gradually implement changes to the Portfolio beginning in the first quarter of 2016. As a result, it is expected that the Portfolio gradually will allocate a larger percentage of its assets to government securities over time until it reaches its new allocation on or about May 2, 2016. Because the yields on government securities generally may be expected to be lower than the yields on comparable non-government securities, it should be expected that the Portfolio’s yield may decrease as more assets are invested in government securities.

Advisory Agreement Board Considerations and Fee Evaluation

Cash Management Fund (the "Fund"), a series of DWS Money Market Trust, invests all of its assets in Cash Management Portfolio (the "Portfolio") in order to achieve its investment objective. The Portfolio’s Board of Trustees approved the renewal of the Portfolio’s investment management agreement (the "Portfolio Agreement") with Deutsche Investment Management Americas Inc. ("DIMA") and the Fund’s Board of Trustees (which consists of the same members as the Board of Trustees of the Portfolio) approved the renewal of the Fund’s investment management agreement with DIMA (the "Fund Agreement," and together with the Portfolio Agreement, the "Agreements") in September 2014. The Portfolio’s Board of Trustees and the Fund’s Board of Trustees are collectively referred to as the "Board."

In terms of the process that the Board followed prior to approving the Agreements, shareholders should know that:

— In September 2014, all of the Portfolio’s and Fund’s Trustees were independent of DIMA and its affiliates.

— The Trustees met frequently during the past year to discuss fund matters and dedicated a substantial amount of time to contract review matters. Over the course of several months, the Board’s Contract Committee, in coordination with the Board’s Fixed Income and Asset Allocation Oversight Committee, reviewed comprehensive materials received from DIMA, independent third parties and independent counsel. These materials included an analysis of performance, fees and expenses, and profitability compiled by a fee consultant retained by the Portfolio’s and the Fund’s Independent Trustees (the "Fee Consultant"). The Board also received extensive information throughout the year regarding performance of the Portfolio and the Fund.

— The Independent Trustees regularly meet privately with counsel to discuss contract review and other matters. In addition, the Independent Trustees were advised by the Fee Consultant in the course of their review of the Portfolio’s and the Fund’s contractual arrangements and considered a comprehensive report prepared by the Fee Consultant in connection with their deliberations.

— In connection with reviewing the Agreements, the Board also reviewed the terms of the Fund’s distribution agreement, administrative services agreement, transfer agency agreement and other material service agreements.

— Based on its evaluation of the information provided, the Contract Committee presented its findings and recommendations to the Board. The Board then reviewed the Contract Committee’s findings and recommendations.

In connection with the contract review process, the Contract Committee and the Board considered the factors discussed below, among others. The Board also considered that DIMA and its predecessors have managed the Portfolio and the Fund since their inception, and the Board believes that a long-term relationship with a capable, conscientious advisor is in the best interests of the Portfolio and the Fund. The Board considered, generally, that shareholders chose to invest or remain invested in the Fund knowing that DIMA managed the Portfolio and the Fund, and that the Fund Agreement was approved by the Fund’s shareholders. DIMA is part of Deutsche Bank AG ("DB"), a major global banking institution that is engaged in a wide range of financial services. The Board believes that there are advantages to being part of a global asset management business that offers a wide range of investing expertise and resources, including hundreds of portfolio managers and analysts with research capabilities in many countries throughout the world.

As part of the contract review process, the Board carefully considered the fees and expenses of each Deutsche fund overseen by the Board in light of the fund’s performance. In many cases, this led to the negotiation and implementation of expense caps. As part of these negotiations, the Board indicated that it would consider relaxing these caps in future years following sustained improvements in performance, among other considerations.

In 2012, DB combined its Asset Management (of which DIMA was a part) and Wealth Management divisions into a new Asset and Wealth Management ("AWM") division. DB has advised the Independent Trustees that the U.S. asset management business is a critical and integral part of DB, and that DB will continue to invest in AWM a significant portion of the savings it has realized by combining its Asset and Wealth Management divisions, including ongoing enhancements to AWM’s investment capabilities. DB also has confirmed its commitment to maintaining strong legal and compliance groups within the AWM division.

While shareholders may focus primarily on fund performance and fees, the Board considers these and many other factors, including the quality and integrity of DIMA’s personnel and such other issues as back-office operations, fund valuations, and compliance policies and procedures.

Nature, Quality and Extent of Services. The Board considered the terms of the Agreements, including the scope of advisory services provided under the Agreements. The Board noted that, under the Agreements, DIMA provides portfolio management services to the Portfolio and the Fund and that, pursuant to separate administrative services agreements, DIMA provides administrative services to the Portfolio and the Fund. The Board considered the experience and skills of senior management and investment personnel, the resources made available to such personnel, the ability of DIMA to attract and retain high-quality personnel, and the organizational depth and stability of DIMA. The Board reviewed the Portfolio’s and the Fund’s performance over short-term and long-term periods and compared those returns to various agreed-upon performance measures, including a peer universe compiled by the Fee Consultant using information supplied by iMoneyNet, an independent fund data service. The Board also noted that it has put into place a process of identifying "Focus Funds" (e.g., funds performing poorly relative to a peer universe), and receives more frequent reporting and information from DIMA regarding such funds, along with DIMA’s plans to address underperformance. The Board believes this process is an effective manner of identifying and addressing underperforming funds. Based on the information provided by the Fee Consultant, the Board noted that for the one- and three-year periods ended December 31, 2013, the Fund’s gross performance (Institutional Shares) was in the 3rd quartile of the applicable iMoneyNet universe (the 1st quartile being the best performers and the 4th quartile being the worst performers).

Fees and Expenses. The Board considered the Portfolio’s and the Fund’s investment management fee schedules and the Fund’s operating expenses and total expense ratios, and comparative information provided by Lipper Inc. ("Lipper") and the Fee Consultant regarding investment management fee rates paid to other investment advisors by similar funds (1st quartile being the most favorable and 4th quartile being the least favorable). With respect to management fees paid to other investment advisors by similar funds, the Board noted that the contractual fee rates paid by the Portfolio and the Fund, which include 0.03% and 0.10% fees paid to DIMA under the respective administrative services agreements, were lower than the median (2nd quartile) of the applicable Lipper peer group (based on Lipper data provided as of December 31, 2013). The Board noted that, although shareholders of the Fund indirectly bear the Portfolio’s management fee, the Fund does not charge an additional investment management fee. Based on Lipper data provided as of December 31, 2013, the Board noted that the Fund’s total (net) operating expenses, which include Portfolio expenses allocated to the Fund, were lower than the median of the applicable Lipper expense universe for Institutional Shares (2nd quartile). The Board also considered how the Fund’s total (net) operating expenses compared to the total (net) operating expenses of a more customized peer group selected by Lipper (based on such factors as asset size). The Board noted the expense limitation agreed to by DIMA. The Board also noted the significant voluntary fee waivers implemented by DIMA to ensure the Fund maintained a positive yield. The Board considered the management fee rate as compared to fees charged by DIMA to comparable funds and considered differences between the Portfolio and Fund and the comparable funds. The information requested by the Board as part of its review of fees and expenses also included information about institutional accounts and funds offered primarily to European investors ("Deutsche Europe funds") managed by DIMA and its affiliates. The Board noted that DIMA indicated that it does not manage any institutional accounts or Deutsche Europe funds comparable to the Portfolio or the Fund.

On the basis of the information provided, the Board concluded that management fees were reasonable and appropriate in light of the nature, quality and extent of services provided by DIMA.

Profitability. The Board reviewed detailed information regarding revenues received by DIMA under the Agreements. The Board considered the estimated costs and pre-tax profits realized by DIMA from advising the Deutsche U.S. mutual funds ("Deutsche Funds"), as well as estimates of the pre-tax profits attributable to managing the Fund in particular. The Board also received information regarding the estimated enterprise-wide profitability of DIMA and its affiliates with respect to all fund services in totality and by fund. The Board and the Fee Consultant reviewed DIMA’s methodology in allocating its costs to the management of the Fund. Based on the information provided, the Board concluded that the pre-tax profits realized by DIMA in connection with the management of the Fund were not unreasonable.

Economies of Scale. The Board considered whether there are economies of scale with respect to the management of the Portfolio and the Fund and whether the Portfolio and the Fund benefit from any economies of scale. The Board noted that the Portfolio’s management fee schedule includes fee breakpoints. The Board concluded that the Portfolio’s and the Fund’s fee schedules represent an appropriate sharing between the Portfolio and the Fund, as the case may be, and DIMA of such economies of scale as may exist in the management of the Portfolio and the Fund at current asset levels.

Other Benefits to DIMA and Its Affiliates. The Board also considered the character and amount of other incidental benefits received by DIMA and its affiliates, including any fees received by DIMA for administrative services provided to the Portfolio and the Fund and any fees received by an affiliate of DIMA for distribution services. The Board also considered benefits to DIMA related to brokerage and soft-dollar allocations, including allocating brokerage to pay for research generated by parties other than the executing broker dealers, which pertain primarily to funds investing in equity securities, along with the incidental public relations benefits to DIMA related to Deutsche Funds advertising and cross-selling opportunities among DIMA products and services. The Board concluded that management fees were reasonable in light of these fallout benefits.

Compliance. The Board considered the significant attention and resources dedicated by DIMA to documenting and enhancing its compliance processes in recent years. The Board noted in particular (i) the experience and seniority of DIMA’s and the Fund’s chief compliance officer; (ii) the large number of DIMA compliance personnel; and (iii) the substantial commitment of resources by DIMA and its affiliates to compliance matters.

Based on all of the information considered and the conclusions reached, the Board unanimously determined that the continuation of the Agreements is in the best interests of the Portfolio and the Fund. In making this determination, the Board did not give particular weight to any single factor identified above. The Board considered these factors over the course of numerous meetings, certain of which were in executive session with only the Independent Trustees and counsel present. It is possible that individual Trustees may have weighed these factors differently in reaching their individual decisions to approve the continuation of the Agreements.
