In the following interview, Cash Management Fund Investment and Treasury Money Fund Investment Lead Portfolio Managers Christine Haddad and Darlene M. Rasel discuss the market environment and the portfolio management team’s approach to managing during the most recent fiscal year.

Q: Will you discuss the market environment for the funds during the year ended December 31, 2005?

A:During the year ended December 31, 2005, the US Federal Reserve (the Fed) continued its recent policy of increasing short-term interest rates in an attempt to undo the easing of monetary policy (i.e., the lowering of interest rates) that occurred through June 2004. In eight increments of 0.25%, the policymakers raised the federal funds rate – the interest rate banks charge when they lend each other money overnight – to 4.25%.

Investment Funds    3

Despite these increases in the federal funds rate, longer-term yields remained low, creating a yield curve – an economic graph with a line going from left to right, showing how high or low yields are from the shortest to the longest maturities – that was atypically flat. (Typically, the line rises from left to right as investors who are willing to tie up their money for a longer period of time are rewarded with higher yields.)

Throughout the year, the Fed repeatedly said that its monetary policy remained “accommodative” to economic growth and that risks in the overall economy between inflation and deflation appeared to be balanced.

Indeed, over the period, the US economy showed resiliency despite two devastating hurricanes and continual increases in energy prices. As the year began, monthly job growth was the most important economic indicator for money markets. However, the focus gradually shifted to inflation, with economists and investors watching carefully for any signs of an increase. Going forward, the markets will likely watch for any changes in policy from incoming Fed Chairman Ben S. Bernanke.

At the end of December 2005, the one-year London Interbank Offered Rate (LIBOR) – the rate of interest at which banks borrow large volumes of funds from other banks in the international market, and the most widely used industry standard for measuring one-year money market rates – was at 4.84%, close to a four-year high. The premium level of the LIBOR (which is set by the market) over the federal funds rate (which is set by the Fed) was 4.25%, representing the market’s concern that the Fed may have to continue raising short-term interest rates to keep the economy’s growth moderate and prevent inflation.

Q: How did the funds perform over its most recent fiscal year?

A:For the period ended December 31, 2005, the funds registered favorable performance and achieved their stated objectives of providing a high level of current income consistent with liquidity and the preservation of capital.

4   Investment Funds

Q: In light of market conditions during the period, what has been the strategy for the fund?

A:During the period, our strategy was to extend maturity somewhat in order to take advantage of select buying opportunities among money market securities with slightly longer maturities and higher yields. For the period, we also increased the fund’s allocation in floating-rate securities. Our decision to increase the fund’s floating-rate position helped to mitigate risks associated with extending maturity. This is because the interest rates of floating rate securities adjust frequently based on indices such as LIBOR and the federal funds rate as market conditions change. These securities provide flexibility in an uncertain interest rate environment.

Q: What has been the strategy for Treasury Money Fund Investment?

A:In 2005, supply/demand issues and higher financing costs (resulting from rising interest rates) made Treasuries expensive relative to other money market instruments. For this reason, we maintained a significant allocation in repurchase agreements, which are agreements between sellers and buyers, usually of government securities, to repurchase securities at a given price and usually at a stated time. For most of the year, the fund’s target portfolio allocation was 70% to 75% in repurchase agreements and 25% to 30% in Treasury bills. With the investments in repurchase agreements, our goal was to keep the fund’s weighted average maturity short, and then step up the yield of the fund at each Fed tightening. With our investments in longer-term Treasury bills and notes, our goal was to lengthen the weighted average maturity and achieve a yield close to the current Fed funds rate until the next Fed tightening, whereupon the Treasury position would be sold or held to maturity. Going forward, we will continue to monitor economic and inflation indicators to determine when the Fed will end its credit tightening program.

Yields are historical, will fluctuate and do not guarantee future performance. The 7-day current yield refers to the income paid by the portfolio over a 7-day period expressed as an annual percentage rate of the fund’s shares outstanding. Please call the Service Center at 1-800-730-1313 for the product’s most recent month-end performance.

Q: What detracted from performance during the period?

A:In the case of Cash Management Fund Investment, in December we kept additional cash on hand – as we do each year – to meet any tax-related redemptions as well as investors’ year-end liquidity needs. Keeping a larger percentage of assets in overnight liquid positions detracted somewhat from yield and total return. For Treasury Money Fund Investment, holding US Treasury securities with maturities of six months or more detracted somewhat from performance due to successive rate increases.

Q: Will you describe your management philosophy?

A:We continue our insistence on the highest credit quality within the funds. We also plan to maintain our conservative investment strategies and standards. We continue to apply a careful approach to investing on behalf of the funds and to seek a competitive yield for our shareholders.

Information About Each 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 Funds limited these expenses; had they not done so, expenses would have been higher. The tables are based on an investment of $1,000 made at the beginning of the six-month period ended December 31, 2005.

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

n

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.

n

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.

Note 1—Organization and Significant Accounting Policies

A. Organization

Cash Management Fund Investment and Treasury Money Fund Investment (each a “Fund” and collectively, the “Funds”) are each a diversified series of DWS Advisor Funds (formerly Scudder Advisor Funds) (the “Trust”), which is registered under the Investment Company Act of 1940, as amended (the “1940 Act”) as an open-end, diversified, management investment company organized as a Massachusetts business trust. The Funds are two of several funds the Trust offers to investors.

The Funds seek to achieve their investment objectives by investing substantially all of their assets in the Cash Management Portfolio and the Treasury Money Portfolio, respectively (each a “Portfolio” and collectively, the “Portfolios”), each an open-end management investment company registered under the 1940 Act and advised by Deutsche Asset Management, Inc. (“DeAM, Inc.” or the “Advisor”). Details concerning each Portfolio’s investment objectives and policies and the risk factors associated with each Portfolio’s investments are described in their respective Prospectuses and Statements of Additional Information.

At December 31, 2005, the Cash Management Fund Investment owned approximately 1% of the Cash Management Portfolio and the Treasury Money Fund Investment owned approximately 28% of the Treasury Money Portfolio. The financial statements of the Portfolios, including the Investment Portfolios, are contained elsewhere in this report and should be read in conjunction with the Funds’ financial statements.

Each 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.

B. Security Valuation

Each Fund determines the valuation of its investment in its Portfolio by multiplying its proportionate ownership of the Portfolio by the total value of the Portfolio’s net assets.

Each Portfolio’s policies for determining the value of its net assets are discussed in each Portfolio’s Financial Statements, which accompany this report.

Investment Funds    19

C. Federal Income Taxes

Each 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 and tax-exempt income to its shareholders. Accordingly, each Fund paid no federal income taxes and no federal income tax provision was required.

At December 31, 2005 Treasury Money Fund Investment had a net tax basis capital loss carryforward of approximately $19,000 which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or December 31, 2012 ($10,000) and December 31, 2013 ($9,000), the respective expiration dates, whichever occurs first.

In addition, from November 1, 2005 through December 31, 2005, the Fund incurred approximately $50 of net realized capital losses. As permitted by tax regulators, the Fund intends to elect to defer these losses and treat them as arising in the fiscal year ended December 31, 2006.

D. Distribution of Income

The net investment income of each Fund is declared as a daily dividend and is distributed to shareholders monthly.

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 Funds.

At December 31, 2005, the Funds’ components of distributable earnings (accumulated losses) on a tax basis were as follows:

	Cash Management		Treasury Money
	Fund Investment		Fund Investment
Undistributed ordinary income*	$	17,533	$	13,439

In addition, the tax character of distributions paid to shareholders by the Funds is summarized as follows:

Years Ended December 31,	2005		2004
Cash Management Fund Investment
Distributions from ordinary income*	$	2,581,745	$	741,692
Distributions from long term-capital gains		26		—
Treasury Money Fund Investment
Distributions form ordinary income*	$	3,558,873	$	1,217,508

* For tax purposes short-term capital gains distributions are considered ordinary income distributions.

20   Investment Funds

E. Contingencies

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

F. Other

Each Fund receives a daily allocation of its respective Portfolio’s net investment income and net realized gains and losses in proportion to its investment in the respective Portfolio. Expenses directly attributed to a fund are charged to that fund, while expenses that are attributed to the Trust are allocated among the Funds in the Trust based on their respective net assets.

Note 2—Fees and Transactions with Affiliates

DeAM, Inc. is the Advisor for each Portfolio and Investment Company Capital Corp. (“ICCC” or the “Administrator”) is the Administrator for each Fund, both indirect, wholly owned subsidiaries of Deutsche Bank AG. Each Fund pays the Administrator an annual fee (“Administrator Service Fee”) based on its average daily net assets which is calculated daily and paid monthly at the annual rate of 0.55%.

For the year ended December 31, 2005 and through April 30, 2006, the Advisor and Administrator have contractually agreed to waive a portion of their fees and/or reimburse expenses of each Fund to the extent necessary to maintain the annualized expenses of the Cash Management Fund Investment and Treasury Money Fund Investment each at 0.75% of their average daily net assets including expenses (excluding extraordinary expenses) of the Cash Management Portfolio and the Treasury Money Portfolio, respectively.

Accordingly, for the year ended December 31, 2005, the Administrator waived a portion of its Administrator Service Fee as follows:

	Total		Amount		Annual
	Aggregated		Waived		Effective Rate
Cash Management Fund Investment	$	574,686	$	80,984		.47%
Treasury Money Fund Investment	$	799,010	$	104,752		.48%

Typesetting and Filing Service Fees. Under an agreement with Deutsche Investment Management Americas Inc. (“DeIM”), an indirect, wholly owned subsidiary of Deutsche Bank AG, DeIM is compensated for providing typesetting and regulatory filing services to the funds. For the year ended December 31, 2005,

Investment Funds    21

the amounts charged to the Funds by DeIM included in the reports to shareholders at December 31, 2005 are as follows:.

	Total		Unpaid at
	Aggregated		December 31, 2005
Cash Management Fund Investment	$	6,360	$	2,100
Treasury Money Fund Investment	$	6,360	$	2,100

Trustees’ Fees and Expenses. As compensation for his or her services, each Independent Trustee receives an aggregate annual fee, plus a fee for each meeting attended (plus reimbursement for reasonable out-of-pocket expenses incurred in connection with his or her attendance at board and committee meetings) from each Fund in the Fund Complex for which he or she serves. In addition, the Chairman of the Fund Complex’s Audit Committee receives an annual fee for his services. Payment of such fees and expenses is allocated among all such Funds described above in direct proportion to their relative net assets.

Note 3—Concentration of Ownership

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

At December 31, 2005, there was one shareholder who held approximately 25% of the outstanding shares of Treasury Money Fund Investment.

Note 4—Regulatory Matters and Litigation

Market Timing Related Regulatory and Litigation Matters. Since at least July 2003, federal, state and industry regulators have been conducting ongoing inquiries and investigations (“inquiries”) into the mutual fund industry, and have requested information from numerous mutual fund companies, including DWS Scudder. The DWS funds’ advisors have been cooperating in connection with these inquiries and are in discussions with the regulators concerning proposed settlements. Publicity about mutual fund practices arising from these industry-wide inquiries serves as the general basis of a number of private lawsuits against the DWS funds. These lawsuits, which previously have been reported in the press, involve purported class action and derivative lawsuits, making various allegations and naming as defendants various persons, including certain DWS funds, the funds’ investment advisors and their affiliates, and certain individuals, including in some cases fund Trustees/ Directors, officers, and other parties. Each DWS fund’s investment advisor has agreed to indemnify the applicable DWS funds in connection with these lawsuits, or other lawsuits or regulatory actions that may be filed making allegations similar to these lawsuits regarding market timing, revenue sharing, fund valuation or

22   Investment Funds

other subjects arising from or related to the pending inquiries. It is not possible to determine with certainty what the outcome of these inquiries will be or what the effect, if any, would be on the funds or their advisors.

With respect to the lawsuits, based on currently available information, the funds’ investment advisors believe the likelihood that the pending lawsuits will have a material adverse financial impact on a DWS fund is remote and such actions are not likely to materially affect their ability to perform under their investment management agreements with the DWS funds.

With respect to the regulatory matters, Deutsche Asset Management (“DeAM”) has advised the funds as follows:

DeAM expects to reach final agreements with regulators early in 2006 regarding allegations of improper trading in the DWS funds. DeAM expects that it will reach settlement agreements with the Securities and Exchange Commission, the New York Attorney General and the Illinois Secretary of State providing for payment of disgorgement, penalties, and investor education contributions totaling approximately $134 million. Approximately $127 million of this amount would be distributed to shareholders of the affected DWS funds in accordance with a distribution plan to be developed by an independent distribution consultant. DeAM does not believe that any of the DWS funds will be named as respondents or defendants in any proceedings. The funds’ investment advisors do not believe these amounts will have a material adverse financial impact on them or materially affect their ability to perform under their investment management agreements with the DWS funds. The above-described amounts are not material to Deutsche Bank, and they have already been reserved.

Based on the settlement discussions thus far, DeAM believes that it will be able to reach a settlement with the regulators on a basis that is generally consistent with settlements reached by other advisors, taking into account the particular facts and circumstances of market timing at DeAM and at the legacy Scudder and Kemper organizations prior to their acquisition by DeAM in April 2002. Among the terms of the expected settled orders, DeAM would be subject to certain undertakings regarding the conduct of its business in the future, including maintaining existing management fee reductions for certain funds for a period of five years. DeAM expects that these settlements would resolve regulatory allegations that it violated certain provisions of federal and state securities laws (i) by entering into trading arrangements that permitted certain investors to engage in market timing in certain DWS funds and (ii) by failing more generally to take adequate measures to prevent market timing in the DWS funds, primarily during the 1999–2001 period. With respect to the trading

Investment Funds    23

arrangements, DeAM expects that the settlement documents will include allegations related to one legacy DeAM arrangement, as well as three legacy Scudder and six legacy Kemper arrangements. All of these trading arrangements originated in businesses that existed prior to the current DeAM organization, which came together in April 2002 as a result of the various mergers of the legacy Scudder, Kemper and Deutsche fund groups, and all of the arrangements were terminated prior to the start of the regulatory investigations that began in the summer of 2003. No current DeAM employee approved the trading arrangements.

There is no certainty that the final settlement documents will contain the foregoing terms and conditions. The independent Trustees/ Directors of the DWS funds have carefully monitored these regulatory investigations with the assistance of independent legal counsel and independent economic consultants. Additional information announced by DeAM regarding the terms of the expected settlements will be made available at www.dws-scudder.com/regulatory settlements, which will also disclose the terms of any final settlement agreements once they are announced.

Other Regulatory Matters. DeAM is also engaged in settlement discussions with the Enforcement Staffs of the SEC and the NASD regarding DeAM’s practices during 2001–2003 with respect to directing brokerage commissions for portfolio transactions by certain DWS funds to broker-dealers that sold shares in the DWS funds and provided enhanced marketing and distribution for shares in the DWS funds. In addition, on January 13, 2006, DWS Scudder Distributors, Inc. received a Wells notice from the Enforcement Staff of the NASD regarding DWS Scudder Distributors’ payment of non-cash compensation to associated persons of NASD member firms, as well as DWS Scudder Distributors’ procedures regarding non-cash compensation regarding entertainment provided to such associated persons. Additional information announced by DeAM regarding the terms of the expected settlements will be made available at www.dws-scudder.com/regulatory settlements, which will also disclose the terms of any final settlement agreements once they are announced.

Note 5—Subsequent Event

Effective February 6, 2006, Scudder Investments changed its name to DWS Scudder and Scudder funds were renamed DWS funds. The DWS Scudder name represents the alignment of Scudder with all of Deutsche Bank’s mutual fund operations around the globe. On February 6, 2006, the funds became part of the DWS family under the letter “D” in the mutual fund listing section of the newspaper. In addition, the Web site for all Scudder funds changed to www.dws-scudder.com

Notes to Financial Statements

Note 1—Organization and Significant Accounting Policies

A. Organization

Cash Management Portfolio and the Treasury Money Portfolio (each a “Portfolio,” and collectively, the “Portfolios”) are registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as open-end, diversified, management investment companies organized as New York business trusts.

Each 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 Portfolios in the preparation of their financial statements.

B. Security Valuation

Each Portfolio’s securities are valued 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 to maturity of any discount or premium.

Investments in open–end investment companies are valued at their net asset value each business day.

C. Repurchase Agreements

Each 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.

Portfolios    43

D. Federal Income Taxes

Each Portfolio is considered a partnership under the Internal Revenue Code, as amended. Therefore, no federal income tax provisions are necessary.

E. Contingencies

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

F. 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.

Each 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.

Note 2—Fees and Transactions with Affiliates

Deutsche Asset Management, Inc., (“DeAM, Inc.” or the “Advisor”), an indirect, wholly owned subsidiary of Deutsche Bank AG, is the Advisor for each of the Portfolios. Under the Advisory Agreement, each Portfolio pays the Advisor an annual fee based on its average daily net assets which is calculated daily and paid monthly at the annual rate of 0.15%.

For the year ended December 31, 2005 and through April 30, 2006, the Advisor and Administrator contractually agreed to waive a portion of their fees and/or reimburse expenses of the Cash Management Portfolio and Treasury Money Portfolio to the extent necessary to maintain operating expenses at 0.18% and 0.20%, respectively, of each Portfolio’s average daily net assets. The amount of the waiver and whether the Advisor and Administrator waive a portion of their fees may vary at any time without notice to the shareholders.

44   Portfolios

Accordingly, for the year ended December 31, 2005, the Advisor waived a portion of its Advisory fee as follows:

	Total		Amount		Annualized
	Aggregated		Waived		Effective Rate
Cash Management Portfolio	$	14,956,589	$	2,700,770		.12	%
Treasury Money Portfolio	$	902,567	$	138,078		.13	%

Investment Company Capital Corp. (“ICCC” or the “Administrator”), also an indirect, wholly owned subsidiary of Deutsche Bank AG, is each Portfolio’s Administrator. Each Portfolio pays the Administrator an annual fee (“Administrator Service Fee”) based on its average daily net assets which is calculated daily and paid monthly at the annual rate of 0.05%.

Trustees’ Fees and Expenses. As compensation for his or her services, each Independent Trustee receives an aggregate annual fee, plus a fee for each meeting attended (plus reimbursement for reasonable out–of–pocket expenses incurred in connection with his or her attendance at board and committee meetings) from each Fund in the Fund Complex for which he or she serves. In addition, the Chairman of the Fund Complex’s Audit Committee receives an annual fee for his services. Payment of such fees and expenses is allocated among all such Funds described above in direct proportion to their relative net assets.

Note 3—Expense Reductions

For the year ended December 31, 2005, the Advisor had agreed to reimburse Cash Management Portfolio and Treasury Money Portfolio $122,118 and $10,473, respectively, which represents a portion of the fee savings expected to be realized by the Advisor related to the outsourcing by the Advisor of certain administrative services to an unaffiliated service provider.

Note 4—Line of Credit

Each Portfolio and several other affiliated funds (the “Participants”) share in a $1.1 billion revolving credit facility administered by J.P. Morgan Chase Bank 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 upon net assets, among each of the Participants. Interest is calculated at the Federal Funds Rate plus 0.5 percent. Each Portfolio may borrow up to a maximum of 5 percent of its net assets under this agreement.

Note 5—Regulatory Matters and Litigation

Market Timing Related Regulatory and Litigation Matters. Since at least July 2003, federal, state and industry regulators have been conducting ongoing inquiries and investigations (“inquiries”) into the mutual fund industry, and have requested information from numerous mutual fund companies, including DWS Scudder. The DWS funds’ advisors have been cooperating in connection with these inquiries and are in discussions with the regulators concerning proposed settlements. Publicity about mutual fund practices arising from these industry-wide inquiries serves as the general basis of a number of private lawsuits against the DWS funds. These lawsuits, which previously have been reported in the press, involve purported class action and derivative lawsuits, making various allegations and naming as defendants various persons, including certain DWS funds, the funds’ investment advisors and their affiliates, and certain individuals, including in some cases fund Trustees/ Directors, officers, and other parties. Each DWS fund’s investment advisor has agreed to indemnify the applicable DWS funds in connection with these lawsuits, or other lawsuits or regulatory actions that may be filed making allegations similar to these lawsuits regarding market timing, revenue sharing, fund valuation or other subjects arising from or related to the pending inquiries. It is not possible to determine with certainty what the outcome of these inquiries will be or what the effect, if any, would be on the funds or their advisors.

With respect to the lawsuits, based on currently available information, the funds’ investment advisors believe the likelihood that the pending lawsuits will have a material adverse financial impact on a DWS fund is remote and such actions are not likely to materially affect their ability to perform under their investment management agreements with the DWS funds.

With respect to the regulatory matters, Deutsche Asset Management (“DeAM”) has advised the funds as follows:

DeAM expects to reach final agreements with regulators early in 2006 regarding allegations of improper trading in the DWS funds. DeAM expects that it will reach settlement agreements with the Securities and Exchange Commission, the New York Attorney General and the Illinois Secretary of State providing for payment of disgorgement, penalties, and investor education contributions totaling approximately $134 million. Approximately $127 million of this amount would be distributed to shareholders of the affected DWS funds in accordance with a distribution plan to be developed by an independent distribution consultant. DeAM does not believe that any of the DWS funds will be named as respondents or defendants in any proceedings. The funds’ investment advisors do not believe these amounts will have a material adverse financial impact on them

46   Portfolios

or materially affect their ability to perform under their investment management agreements with the DWS funds. The above-described amounts are not material to Deutsche Bank, and they have already been reserved.

Based on the settlement discussions thus far, DeAM believes that it will be able to reach a settlement with the regulators on a basis that is generally consistent with settlements reached by other advisors, taking into account the particular facts and circumstances of market timing at DeAM and at the legacy Scudder and Kemper organizations prior to their acquisition by DeAM in April 2002. Among the terms of the expected settled orders, DeAM would be subject to certain undertakings regarding the conduct of its business in the future, including maintaining existing management fee reductions for certain funds for a period of five years. DeAM expects that these settlements would resolve regulatory allegations that it violated certain provisions of federal and state securities laws (i) by entering into trading arrangements that permitted certain investors to engage in market timing in certain DWS funds and (ii) by failing more generally to take adequate measures to prevent market timing in the DWS funds, primarily during the 1999–2001 period. With respect to the trading arrangements, DeAM expects that the settlement documents will include allegations related to one legacy DeAM arrangement, as well as three legacy Scudder and six legacy Kemper arrangements. All of these trading arrangements originated in businesses that existed prior to the current DeAM organization, which came together in April 2002 as a result of the various mergers of the legacy Scudder, Kemper and Deutsche fund groups, and all of the arrangements were terminated prior to the start of the regulatory investigations that began in the summer of 2003. No current DeAM employee approved the trading arrangements.

There is no certainty that the final settlement documents will contain the foregoing terms and conditions. The independent Trustees/ Directors of the DWS funds have carefully monitored these regulatory investigations with the assistance of independent legal counsel and independent economic consultants. Additional information announced by DeAM regarding the terms of the expected settlements will be made available at www.dws-scudder.com/regulatory settlements, which will also disclose the terms of any final settlement agreements once they are announced.

Other Regulatory Matters. DeAM is also engaged in settlement discussions with the Enforcement Staffs of the SEC and the NASD regarding DeAM’s practices during 2001–2003 with respect to directing brokerage commissions for portfolio transactions by certain DWS funds to broker-dealers that sold shares in the DWS funds and provided enhanced marketing and distribution for shares in the DWS

funds. In addition, on January 13, 2006, DWS Scudder Distributors, Inc. received a Wells notice from the Enforcement Staff of the NASD regarding DWS Scudder Distributors’ payment of non-cash compensation to associated persons of NASD member firms, as well as DWS Scudder Distributors’ procedures regarding non-cash compensation regarding entertainment provided to such associated persons. Additional information announced by DeAM regarding the terms of the expected settlements will be made available at www.dws-scudder.com/regulatory settlements, which will also disclose the terms of any final settlement agreements once they are announced.

Investment Management Agreement Approval

Cash Management Fund Investment

Cash Management Fund Investment (the “Fund”), a series of the DWS Advisor Funds (the “Trust”), invests all of its assets in the Cash Management Portfolio (the “Portfolio”) in order to achieve its investment objectives. The Board of Trustees of the Portfolio, which is also the Board of Trustees of the Trust, approved the continuation of the current investment management agreement with Deutsche Asset Management, Inc. (the “Advisor”) in September 2005. In terms of the process the Trustees followed prior to approving the contract, shareholders should know that:

n	At the present time, all but one of the Portfolio’s and the Fund’s Trustees are independent of the Advisor and its affiliates.
n	The Trustees meet frequently to discuss fund matters. Each year, the Trustees dedicate part or all of several meetings to contract review matters.
n	The Trustees regularly meet privately with their independent counsel (and, as needed, other advisors) to discuss contract review and other matters.

The Advisor and its predecessors have managed the Portfolio since inception, and the Trustees believe that a long-term relationship with a capable, conscientious advisor is in the best interest of shareholders. As you may know, the Advisor is part of Deutsche Bank, a major global banking institution that is engaged in a wide range of financial services. The Trustees believe that there are significant advantages to being part of a global asset management business with extensive investing expertise and resources, including hundreds of portfolio managers and analysts with research capabilities in many countries throughout the world.

Shareholders may focus only on fund performance and fees, but the Portfolio’s Trustees consider these and many other factors, including the quality and integrity of the Advisor’s personnel and back-office operations, fund valuations, and compliance policies and procedures. The Trustees noted that the Advisor has also implemented new, forward-looking policies and procedures in many important areas, such as those involving brokerage commissions and so-called “soft dollars”, even when not obligated to do so by law or regulation.

50   Portfolios

In determining to approve the continuation of the Portfolio’s current investment management agreement, the Trustees considered factors that it believes relevant to the interests of shareholders, including:

n	The investment management fee schedule for the Fund, including (i) comparative information provided by Lipper regarding investment management fee rates paid to other investment advisors by similar funds and (ii) fee rates paid to the Advisor by similar funds and institutional accounts advised by the Advisor. With respect to management fees paid to other investment advisors by similar funds, the Trustees noted that the fee rate paid by the Fund was lower than the median (1st quartile) of the applicable Lipper universe as of December 31, 2004. The Board gave only limited consideration to fees paid by similar institutional accounts advised by the Advisor, in light of the material differences in the scope of services provided to mutual funds as compared to those provided to institutional accounts. The Board concluded that the fee schedule in effect for the Fund represented reasonable compensation in light of the nature, extent and quality of the services being provided to the Portfolio, the performance of the Portfolio and fees paid by similar funds.
n	The extent to which economies of scale would be realized as the Portfolio grows. In this regard, the Board noted that the Portfolio’s investment management fee schedule includes no fee breakpoints but concluded that the fee schedule is appropriate given current asset levels.
n	The total operating expense of the Fund relative to the Fund’s peer group as determined by Lipper. In this regard, the Board noted that the total expenses of the Fund for the year ended December 31, 2004 were more than the median (3rd quartile) of the applicable Lipper universe. The Board also considered the expense limitations agreed to by the Advisor that serve to ensure that the Fund’s total operating expenses would be competitive relative to the applicable Lipper universe.
n	The investment performance of the Fund and the Advisor relative to industry peer groups. The Board noted that for the one-, three- and five-year periods ended June 30, 2005, the Fund’s performance was in the 2nd, 3rd and 3nd quartiles, respectively of the applicable iMoneyNet universe. The Board also observed that the Fund outperformed its benchmark in the one-year period but underperformed in the three- and five-year periods. The

Portfolios    51

	Board recognized that the Advisor has made significant changes in its investment personnel and processes in recent years in an effort to improve long-term performance.
n	The nature, extent and quality of the advisory services provided by the Advisor. The Board considered extensive information regarding the Advisor, including the Advisor’s personnel, particularly those personnel with responsibilities for providing services to the Portfolio, resources, policies and investment processes. The Board also considered the terms of the current investment management agreement, including the scope of services provided under the agreement. In this regard, the Board concluded that the quality and range of services provided by the Advisor have benefited, and should continue to benefit, the Fund and its shareholders.
n	The costs of the services to, and profits realized by, the Advisor and its affiliates from their relationships with the Portfolio and the Fund. The Board reviewed information concerning the costs incurred and profits realized by the Advisor during 2004 from providing investment management services to the Portfolio and, separately, to the entire DWS fund complex, and reviewed with the Advisor the cost allocation methodology used to determine its profitability. In analyzing the Advisor’s costs and profits, the Board also reviewed the fees paid to, and services provided to the Fund by the Advisor and its affiliates. As part of this review, the Board considered information provided by an independent accounting firm engaged to review the Advisor’s cost allocation methodology and calculations. The Board concluded that the Portfolio’s investment management fee schedule represented reasonable compensation in light of the costs incurred by the Advisor and its affiliates in providing services to the Portfolio and the Fund. The Board also reviewed information regarding the profitability of certain similar investment management firms. The Board noted that while information regarding the profitability of such firms is limited, the Advisor’s overall profitability with respect to the DWS fund complex (after taking into account distribution and other services provided by the Advisor and its affiliates) was lower than the overall profitability levels of most comparable firms for which such data was available.
n	The practices of the Advisor regarding the selection and compensation of brokers and dealers executing portfolio transactions for the Portfolio,

52   Portfolios

	including the Advisor’s soft dollar practices. In this regard, the Board observed that the Advisor had voluntarily terminated the practice of allocating brokerage commissions to acquire research services from third-party service providers. The Board indicated that it would continue to monitor the Portfolio’s trading activities to ensure that the principle of “best price and execution” remains paramount in the portfolio trading process.
n	The Advisor’s commitment to, and record of, compliance including its written compliance policies and procedures. In this regard, the Board considered the Advisor’s commitment to indemnify the Fund against any costs and liabilities related to lawsuits or regulatory actions making allegations regarding market timing, revenue sharing, fund valuation or other subjects arising from or relating to pending regulatory inquiries. The Board also considered the significant attention and resources dedicated by the Advisor to documenting and enhancing its compliance processes in recent years. The Board noted in particular (i) the experience and seniority of the Advisor’s chief compliance officer, who reports to the Board, (ii) the large number of compliance personnel who report to the Advisor’s chief compliance officer, and (iii) the substantial commitment of resources by the Advisor to compliance matters.
n	Deutsche Bank’s commitment to restructuring and growing its US mutual fund business. The Board considered recent and ongoing efforts by Deutsche Bank to restructure its US mutual fund business to improve efficiency and competitiveness and to reduce compliance and operational risk. The Board considered assurances received from Deutsche Bank that it would commit the resources necessary to maintain high quality services to the Portfolio and the Fund and its shareholders as long as they remained in existence and while various organizational initiatives are being implemented. The Board also considered Deutsche Bank’s strategic plans for investing in the growth of its US mutual fund business and the potential benefits to the Fund’s shareholders.

Based on all of the foregoing, the Board determined to continue the Portfolio’s current investment management agreement, and concluded that the continuation of the agreement was in the best interests of shareholders. In reaching this conclusion the Board did not give particular weight to any single factor identified above. The Board considered these factors over the course of

Portfolios    53

numerous meetings, many of which were in executive session with only the Independent Trustees and their 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 current agreement.

Treasury Money Fund Investment

Treasury Money Fund Investment (the “Fund”), a series of the DWS Advisor Funds (the “Trust”), invests all of its assets in the Treasury Money Portfolio (the “Portfolio”) in order to achieve its investment objectives. The Board of Trustees of the Portfolio, which is also the Board of Trustees of the Trust, approved the continuation of the current investment management agreement with Deutsche Asset Management, Inc. (the “Advisor”) in September 2005. In terms of the process the Trustees followed prior to approving the contract, shareholders should know that:

The Board gave only limited consideration to fees paid by similar institutional accounts advised by the Advisor, in light of the material differences in the scope of services provided to mutual funds as compared to those provided to institutional accounts. The Board concluded that the fee schedule in effect for the Fund represented reasonable compensation in light of the nature, extent and quality of the services being provided to the Portfolio, the performance of the Portfolio and fees paid by similar funds.
n	The extent to which economies of scale would be realized as the Portfolio grows. In this regard, the Board noted that the Portfolio’s investment management fee schedule includes no fee breakpoints but that the Portfolio’s total assets are less than $600 million. The Board concluded that the Fund’s fee schedule is appropriate given current asset levels.
n	The total operating expense of the Fund relative to the Fund’s peer group as determined by Lipper. In this regard, the Board noted that the total expenses of the Fund for the year ending December 31, 2004 were higher than the median (3rd quartile) of the applicable Lipper universe. The Board also considered the expense limitations agreed to by the Advisor that serve to ensure that the Fund’s total operating expenses would be competitive relative to the applicable Lipper universe.
n	The investment performance of the Fund and the Advisor relative to industry peer groups. The Board noted that for the one-, three- and five-

Portfolios    55

	year periods ended June 30, 2005, the Fund’s performance was in the 2nd, 3rd, and 3rd quartiles, respectively, of the applicable iMoneyNet universe. The Board also observed that the Fund outperformed its benchmark in the one-year period, but slightly underperformed its benchmark in the three- and five-year periods. The Board recognized that the Advisor has made significant changes in its investment personnel and processes in recent years in an effort to improve long-term performance.
n	The nature, extent and quality of the advisory services provided by the Advisor. The Board considered extensive information regarding the Advisor, including the Advisor’s personnel, particularly those personnel with responsibilities for providing services to the Portfolio, resources, policies and investment processes. The Board also considered the terms of the current investment management agreement, including the scope of services provided under the agreement. In this regard, the Board concluded that the quality and range of services provided by the Advisor have benefited, and should continue to benefit, the Fund and its shareholders.
n	The costs of the services to, and profits realized by, the Advisor and its affiliates from their relationships with the Portfolio and the Fund. The Board reviewed information concerning the costs incurred and profits realized by the Advisor during 2004 from providing investment management services to the Portfolio and, separately, to the entire DWS fund complex, and reviewed with the Advisor the cost allocation methodology used to determine its profitability. In analyzing the Advisor’s costs and profits, the Board also reviewed the fees paid to, and services provided to the Fund by the Advisor and its affiliates with respect to administrative services, fund accounting, shareholder servicing and distribution (including fees paid pursuant to 12b-1 plans). As part of this review, the Board considered information provided by an independent accounting firm engaged to review the Advisor’s cost allocation methodology and calculations. The Board concluded that the Portfolio’s investment management fee schedule represented reasonable compensation in light of the costs incurred by the Advisor and its affiliates in providing services to the Portfolio and the Fund. The Board also reviewed information regarding the profitability of certain similar investment management firms. The Board noted that while information regarding the profitability of such firms is limited, the Advisor’s overall profitability with respect to the DWS fund complex (after taking into

56   Portfolios

	account distribution and other services provided by the Advisor and its affiliates) was lower than the overall profitability levels of most comparable firms for which such data was available.
n	The practices of the Advisor regarding the selection and compensation of brokers and dealers executing portfolio transactions for the Portfolio, including the Advisor’s soft dollar practices. In this regard, the Board observed that the Advisor had voluntarily terminated the practice of allocating brokerage commissions to acquire research services from third-party service providers. The Board indicated that it would continue to monitor the Portfolio’s trading activities to ensure that the principle of “best price and execution” remains paramount in the portfolio trading process.
n	The Advisor’s commitment to, and record of, compliance including its written compliance policies and procedures. In this regard, the Board considered the Advisor’s commitment to indemnify the Fund against any costs and liabilities related to lawsuits or regulatory actions making allegations regarding market timing, revenue sharing, fund valuation or other subjects arising from or relating to pending regulatory inquiries. The Board also considered the significant attention and resources dedicated by the Advisor to documenting and enhancing its compliance processes in recent years. The Board noted in particular (i) the experience and seniority of the Advisor’s chief compliance officer, who reports to the Board, (ii) the large number of compliance personnel who report to the Advisor’s chief compliance officer, and (iii) the substantial commitment of resources by the Advisor to compliance matters.
n	Deutsche Bank’s commitment to restructuring and growing its US mutual fund business. The Board considered recent and ongoing efforts by Deutsche Bank to restructure its US mutual fund business to improve efficiency and competitiveness and to reduce compliance and operational risk. The Board considered assurances received from Deutsche Bank that it would commit the resources necessary to maintain high quality services to the Portfolio and the Fund and its shareholders as long as they remained in existence and while various organizational initiatives are being implemented. The Board also considered Deutsche Bank’s strategic plans for investing in the growth of its US mutual fund business and the potential benefits to the Fund’s shareholders.

Based on all of the foregoing, the Board determined to continue the Portfolio’s current investment management agreement, and concluded that the continuation of the agreement was in the best interests of shareholders. In reaching this conclusion the Board did not give particular weight to any single factor identified above. The Board considered these factors over the course of numerous meetings, many of which were in executive session with only the Independent Trustees and their 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 current agreement.

ITEM 2. CODE OF ETHICS.

As of the end of the period, December 31, 2005, DWS Advisor Funds has adopted a code of ethics, as defined in Item 2 of Form N-CSR, that applies to its Principal Executive Officer and Principal Financial Officer.

There have been no amendments to, or waivers from, a provision of the code of ethics during the period covered by this report that would require disclosure under Item 2.

A copy of the code of ethics is filed as an exhibit to this Form N-CSR.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Fund’s Board of Directors/Trustees has determined that the Fund has at least one “audit committee financial expert” serving on its audit committee: Mr. Graham E. Jones. This audit committee member is “independent,” meaning that he is not an “interested person” of the Fund (as that term is defined in Section 2(a)(19) of the Investment Company Act of 1940) and he does not accept any consulting, advisory, or other compensatory fee from the Fund (except in the capacity as a Board or committee member).

An “audit committee financial expert” is not an “expert” for any purpose, including for purposes of Section 11 of the Securities Act of 1933, as a result of being designated as an “audit committee financial expert.” Further, the designation of a person as an “audit committee financial expert” does not mean that the person has any greater duties, obligations, or liability than those imposed on the person without the “audit committee financial expert” designation. Similarly, the designation of a person as an “audit committee financial expert” does not affect the duties, obligations, or liability of any other member of the audit committee or board of directors.
