Portfolio Management Review

In the following interview, the portfolio management team discusses
the market environment and the performance of Cash Account
Trust  Davidson Cash Equivalent Shares and Davidson Cash
Equivalent Plus Shares during the most recent annual period ended
April 30, 2009.

The views expressed in the following discussion reflect those of the portfolio management
team only through the end of the period of the report as stated on the cover. The
management team's views are subject to change at any time based on market and other
conditions and should not be construed as a recommendation. Past performance is no
guarantee of future results. Current and future portfolio holdings are subject to risk.

Q: Will you discuss the market environment for the portfolios
during the most recent annual period?

A:During the past 12 months the financial markets experienced
a series of unprecedented and earthshaking events. The massive
credit crunch that originated with problems in the US subprime
mortgage market as well as securitized mortgages eventually
brought down several financial firms, including Lehman Brothers,
and transformed Wall Street. September through November 2008
were exceptionally traumatic months for the financial industry,
as severe losses and the general liquidity squeeze forced
several major financial companies to seek rescue through a
government bailout or a merger.

The loss of market liquidity forced the US Federal Reserve Board
(the Fed) and other central banks to make significant efforts to
boost liquidity by creating expansive lending facilities. In late
2008, among other unprecedented actions, the US government
placed Fannie Mae (Federal National Mortgage Association) and
Freddie Mac (Federal Home Loan Mortgage Corporation) in
conservatorship of the Federal Housing Finance Agency, a
newly-created regulator, inject $700 billion into the banking
system through the Troubled Asset Relief Program ("TARP") and
offer a stimulus package to US consumers. In response to a
freeze-up in money market liquidity, the government created new
lending facilities for commercial paper.1 In 2009, the new
administration introduced an additional series of initiatives to deal
with financial market turbulence. These included a second large
stimulus package; "quantitative easing" by the Fed (where the
Fed injected billions into the financial system by buying up
Treasuries and mortgage-backed securities in order to lower
interest rates); and Treasury Secretary Geithner's Public-Private
Investment Plan designed to repair the balance sheets of
struggling banks. By the close of the period, it seemed evident
that the array of government programs had improved investor
sentiment and the overall tone of the financial markets. And in
general  except for the labor market  the rate of deterioration
for US economic data seemed to be slowing. However, because
of continued heavy demand for money market instruments and a
shrinkage in supply (especially within the commercial paper
market), yields of money market securities declined significantly
during the latter portion of the 12-month period.

As of April 30, 2009, three-month LIBOR, an industry standard for
measuring three-month taxable money market rates, stood at
1.02%, compared with 2.85% as of April 30, 2008.2

Portfolio Performance(as of April 30, 2009)

Performance is historical and does not guarantee future results. Current
performance may be lower or higher than the performance data quoted.

An investment in a money market fund is not insured or guaranteed by the FDIC
or any other government agency. Although money market funds seek to preserve
the value of your investment at $1.00 per share, this share price isn't guaranteed
and you could lose money by investing in money market funds. 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 portfolios' $1.00 share price. The credit quality of the portfolios' holdings can
change rapidly in certain markets, and the default of a single holding could have an
adverse impact on the portfolios' share price. The portfolios' share price can also be
negatively affected during periods of high redemption pressures and/or illiquid markets.
The actions of a few large investors in one class of shares of a fund may have a
significant adverse effect on the share prices of all classes of shares of that fund.

|Yields are historical, will fluctuate and do not guarantee future performance. The
7-day current yield refers to the income paid by the portfolios over a 7-day period
expressed as an annual percentage rate of the portfolios' shares outstanding. For the
most current yield information, call (800) 332-5915.
*Recent and future declines in interest rate levels could cause the portfolio's earnings to
fall below each portfolio's expense ratio, resulting in a negative yield. The investment
advisor has agreed to voluntarily waive fees/reimburse expenses as necessary to
maintain a minimum distribution yield. This waiver may be changed or terminated at any
time without notice. Otherwise, the 7-day current yield for Davidson Cash Equivalent
Shares would have been -0.14% and -0.50% for the Money Market Portfolio and the
Government & Agency Securities Portfolio, respectively, and -0.04% and -0.37% for
Davidson Cash Equivalent Plus Shares for the Money Market Portfolio and Government
& Agency Securities Portfolio, respectively, as of April 30, 2009.**Performance reflects a partial fee waiver which improved results during the period.
Without fee waivers, the 7-day current yield of the Tax-Exempt Portfolio  Davidson
Cash Equivalent Shares would have been 0.03% as of April 30, 2009.***The equivalent taxable yield allows you to compare with the performance of taxable
money market funds. For the Tax-Exempt Portfolio, the equivalent taxable yield is based
upon the marginal income tax rate of 35%. Income may be subject to local taxes and
for some investors, the alternative minimum tax.

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

A:We were able to maintain a yield for the portfolios that is
competitive, though certainly low, given very difficult market
conditions. (All performance is historical and does not guarantee
future results. Yields fluctuate and are not guaranteed.)

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

A:Given the difficult situation throughout the investment
markets, and understanding that the credit crunch would not be a
short-term phenomenon, our strategy for the portfolio through the
summer of 2008 was to emphasize liquidity and high credit
quality while looking for ways to maximize yield potential when
opportunities presented themselves. In mid-September, when
conditions in the money markets worsened drastically, we
enacted a significantly more defensive strategy, holding more
overnight securities in the form of repurchase agreements.3 We
also purchased Treasury and agency instruments as well as
corporate commercial paper and sovereign securities (direct
issuance by foreign governments) in seeking the highest-quality
portfolio given the extremely difficult market environment. As
market conditions eased during the end of the period, we have
looked for opportunities to boost yield without increasing the
portfolio's overall risk level, utilizing the highest-quality securities.

Q: What has been the strategy for the Government & Agency
Securities Portfolio?

A:As the Fed began to significantly lower short-term rates in
response to a wavering economy and the pervasive credit crunch,
we reduced the portfolio's repurchase agreement position in favor
of fixed-rate agency securities in order to lock in as much yield as
possible. We also added agency floating-rate notes to boost
return. As of the close of the period, the portfolio was still
weighted heavily towards maintaining a high level of liquidity.

Q: What has been the strategy for the Tax-Exempt Portfolio?

A:In searching for possible investments, we continued to focus
on the highest-quality securities while seeking competitive yields
across the municipal investment spectrum. During a difficult
period for the credit markets, we sought to balance higher yield
with top quality by maintaining a strong position in floating-rate
securities as we took advantage of comparatively higher
floating-rate interest coupons. The interest rate of floating-rate
securities adjusts periodically based on indices such as the
Securities Industry and Financial Market Association Index of
Variable Rate Demand Notes.4 Because the interest rates of
these instruments adjust as market conditions change, they
provide flexibility in an uncertain interest rate environment. In
addition, we took a cautious approach in extending maturity. In
part, this was because of the decline of the monoline insurance
industry.5 Even before several of the monoline insurers lost their
AAA ratings, our policy has been to look beyond security ratings,
examining the underlying creditworthiness of each issue closely,
and choosing what we consider to be safe and highly liquid
securities.6 In addition, when considering longer-term fixed-rate
securities, we limited our purchases to the strongest credits. By
the end of the period, we had made select purchases of what we
believed to be very liquid credits of longer maturity in order to
boost yield.

Q: What detracted from performance during the period?

A:The types of securities that we were investing in tended to
have lower yields than issues carrying more risk. We preferred to
be cautious during a time of significant market turbulence. In the
end this cost the portfolios some yield, but we believe that this
represented a prudent approach to preserving principal.

Q: Will you describe your investment philosophy?

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

Information About Each Portfolio's Expenses

As an investor of a Portfolio, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management
fees, distribution and service (12b-1) fees and other Portfolio 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 each Portfolio 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 Portfolios limited
these expenses; had they not done so, expenses would have been higher
for the Davidson Cash Equivalent Shares and the Davidson Cash
Equivalent Plus Shares. 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 (November 1, 2008 to April 30, 2009).

The tables illustrate each Portfolio's expenses in two ways:

•    Actual Portfolio Return. This helps you estimate the actual dollar
amount of ongoing expenses (but not transaction costs) paid on a
$1,000 investment in each Portfolio using each Portfolio'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% Portfolio Return. This helps you to compare each
Portfolio's ongoing expenses (but not transaction costs) with those of
other mutual funds using each Portfolio'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.

144A: Security exempt from registration under Rule 144A of the Securities Act of 1933.
These securities may be resold in transactions exempt from registration, normally to
qualified institutional buyers.

Interest Only: Interest Only (IO) bonds represent the "interest only" portion of payments on
a pool of underlying mortgages or mortgage-backed securities. IO securities are subject to
prepayment risk of the pool of underlying mortgages.

Fair Value Measurements

Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157,
"Fair Value Measurements," establishes a three-tier hierarchy for measuring fair value and
requires additional disclosure about the classification of 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 inputs or methodology used for valuing
securities are not necessarily an indication of the risk associated with investing in those
securities. Most securities held by a money market fund are reflected as Level 2 because
the securities are valued at amortized cost (which approximates fair value) and, accordingly,
the inputs used to determine value are not quoted prices in an active market.

The following is a summary of the inputs used as of April 30, 2009 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 the
Financial Statements.

Interest Only: Interest Only (IO) bonds represent the "interest only" portion of payments on
a pool of underlying mortgages or mortgage-backed securities. IO securities are subject to
prepayment risk of the pool of underlying mortgages.

Principal Only: Principal Only (PO) bonds represent the "principal only" portion of payments
on a pool of underlying mortgages or mortgage-backed securities.

Fair Value Measurements

Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157,
"Fair Value Measurements," establishes a three-tier hierarchy for measuring fair value and
requires additional disclosure about the classification of 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 inputs or methodology used for valuing
securities are not necessarily an indication of the risk associated with investing in those
securities. Most securities held by a money market fund are reflected as Level 2 because
the securities are valued at amortized cost (which approximates fair value) and, accordingly,
the inputs used to determine value are not quoted prices in an active market.

The following is a summary of the inputs used as of April 30, 2009 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 the
Financial Statements.

144A: Security exempt from registration under Rule 144A of the Securities Act of 1933.
These securities may be resold in transactions exempt from registration, normally to
qualified institutional buyers.

securities which are held in escrow and used to pay principal and interest on tax-exempt
issues and to retire the bonds in full at the earliest refunding date.

Fair Value Measurements

Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157,
"Fair Value Measurements," establishes a three-tier hierarchy for measuring fair value and
requires additional disclosure about the classification of 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 inputs or methodology used for valuing
securities are not necessarily an indication of the risk associated with investing in those
securities. Most securities held by a money market fund are reflected as Level 2 because
the securities are valued at amortized cost (which approximates fair value) and, accordingly,
the inputs used to determine value are not quoted prices in an active market.

The following is a summary of the inputs used as of April 30, 2009 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 the
Financial Statements.

Notes to Financial Statements

1. Significant Accounting Policies

Cash Account Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end
investment management company organized as a Massachusetts
business trust.

The Trust offers three portfolios: Money Market Portfolio, Government &
Agency Securities Portfolio and Tax-Exempt Portfolio (the "Portfolios").

Money Market Portfolio offers nine classes of shares: Capital Assets
Funds Shares, Capital Assets Funds Preferred Shares, Davidson Cash
Equivalent Shares, Davidson Cash Equivalent Plus Shares, Institutional
Money Market Shares, Institutional Select Money Market Shares, Premier
Money Market Shares, Premium Reserve Money Market Shares and
Service Shares.

Government & Agency Securities Portfolio offers eight classes of shares:
Capital Assets Funds Shares, Davidson Cash Equivalent Shares, Davidson
Cash Equivalent Plus Shares, DWS Government & Agency Money Fund,
DWS Government Cash Institutional Shares, Government Cash Managed
Shares, Premier Money Market Shares and Service Shares.

Tax-Exempt Portfolio offers nine classes of shares: Capital Assets Funds
Shares, Davidson Cash Equivalent Shares, DWS Tax-Exempt Cash
Institutional Shares, DWS Tax-Exempt Money Fund, DWS Tax-Free Money
Fund Class S, Premier Money Market Shares, Service Shares, Tax-Exempt
Cash Managed Shares and Tax-Free Investment Class.

The financial highlights for all classes of shares, other than Davidson Cash
Equivalent Shares and Davidson Cash Equivalent Plus Shares, are
provided separately and are available upon request.

Each Portfolio's investment income, realized and unrealized gains and
losses, and certain Portfolio-level expenses and expense reductions, if
any, are borne pro rata on the basis of relative net assets by the holders of
all classes of shares of that Portfolio, except that each class bears certain
expenses unique to that class such as distribution and service fees,
services to shareholders and certain other class-specific expenses.
Differences in class-level expenses may result in payment of different per
share dividends by class. All shares of the Trust have equal rights with
respect to voting subject to class-specific arrangements.

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.

Security Valuation. Portfolio 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 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.

Each Portfolio adopted Financial Accounting Standards Board ("FASB")
Statement of Financial Accounting Standards No. 157, "Fair Value
Measurements" ("FAS 157"), effective at the beginning of each Portfolio's
fiscal year. Disclosure about the classification of fair value measurements
is included at the end of each Portfolio's Investment Portfolio.

New Accounting Pronouncement. In April 2009, FASB issued FASB Staff
Position No. 157-4, "Determining Fair Value When the Volume and Level
of Activity for the Asset or Liability Have Significantly Decreased and
Identifying Transactions That Are Not Orderly" ("FSP 157-4"). FSP 157-4
provides additional guidance for estimating fair value in accordance with
FAS 157, when the volume and level of activity for the asset or liability
have significantly decreased as well as guidance on identifying
circumstances that indicate a transaction is not orderly. FSP 157-4 is
effective for fiscal years and interim periods ending after June 15, 2009.
Management is currently reviewing the enhanced disclosure
requirements for the adoption of FSP 157-4.

Repurchase Agreements. Each Portfolio may enter into repurchase
agreements with certain banks and broker/dealers whereby each 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 custodial 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 Portfolios have the right to sell the securities and
recover any resulting loss from the financial institution. If the financial
institution enters into bankruptcy, the Portfolios' claims on the collateral
may be subject to legal proceedings.

Federal Income Taxes. Each of the Portfolios' policies 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.

The Portfolios have reviewed the tax positions for the open tax years as of
April 30, 2009 and have determined that no provision for income tax is
required in the Portfolios' financial statements. The Portfolios' federal tax
returns for the prior three fiscal years remain subject to examination by
the Internal Revenue Service.

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

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

At April 30, 2009, the Portfolios' components of distributable earnings on
a tax-basis are as follows:

|Money Market Portfolio:
Undistributed ordinary income                   | $       714,514  
|----------------------------------------------------------------------- | -----------------
|Government & Agency Securities Portfolio:
Undistributed ordinary income | $       3,347,908
|Tax-Exempt Portfolio:
Undistributed tax-exempt income                   | $       1,449,524

In addition, during the years ended April 30, 2009 and April 30, 2008, the
tax character of distributions paid to shareholders by each Portfolio is
summarized as follows:

|Portfolio                                                                    | Years Ended April 30,
|---------------------------------------------------------------------------- | ---------------------

|Money Market Portfolio:
Distributions from ordinary income*                  | $       62,191,415   
|Government & Agency Securities Portfolio:
Distributions from ordinary income | $       104,415,283  
|Tax-Exempt Portfolio:
Distributions from tax-exempt income                   | $       58,316,635   
|Distributions from ordinary income*                                          | $       144,235      
|Distributions from long-term capital gains                                   | $       48,222       

Expenses. Expenses of the Trust arising in connection with a specific
Portfolio are allocated to that Portfolio. Other Trust expenses which cannot
be directly attributed to a Portfolio are apportioned pro rata on the basis of
relative net assets among the Portfolios in the Trust.

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 expect 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
premiums and discounts are amortized/accreted for both tax and financial
reporting purposes.

2. Related Parties

Management Agreement. Under an Investment Management Agreement
and an Amended and Restated Investment Management Agreement
(with respect to the Government & Agency Securities Portfolio and
Tax-Exempt Portfolio) between the Trust and Deutsche Investment
Management Americas Inc. ("DIMA" or the "Advisor"), an indirect, wholly
owned subsidiary of Deutsche Bank AG, the Advisor directs the
investments of the Portfolios in accordance with their respective
investment objectives, policies and restrictions. The Advisor determines
the securities, instruments and other contracts relating to investments to
be purchased, sold or entered into by each Portfolio.

Prior to June 1, 2008, in addition to portfolio management services, the
Advisor provided certain administrative services in accordance with the
Investment Management Agreement. For the period from May 1, 2008
through May 31, 2008, the Portfolios paid a monthly management fee
based on the Trust's combined average daily net assets, computed and
accrued daily and payable monthly, at 1/12 of the following annual rates:

|First $500 million of the Trust's combined average daily net assets | .220%
|------------------------------------------------------------------- | -----
|Next $500 million of such net assets                                | .200%
|Next $1 billion of such net assets                                  | .175%
|Next $1 billion of such net assets                                  | .160%
|Over $3 billion of such net assets                                  | .150%

The Investment Management Agreement, including this fee schedule, has
remained in effect for the Money Market Portfolio.

Effective June 1, 2008, under the Amended and Restated Investment
Management Agreement with the Advisor, the Government & Agency
Securities Portfolio and Tax-Exempt Portfolio pay a monthly management
fee based on the Trust's combined average daily net assets, computed
and accrued daily and payable monthly, at the following annual rates:

|First $500 million of the Trust's combined average daily net assets | .120%
|------------------------------------------------------------------- | -----
|Next $500 million of such net assets                                | .100%
|Next $1 billion of such net assets                                  | .075%
|Next $1 billion of such net assets                                  | .060%
|Over $3 billion of such net assets                                  | .050%

For the period from February 15, 2007 through May 31, 2008, the Advisor
had agreed to contractually reduce its management fee for the
Government & Agency Securities Portfolio such that the annual effective
rate was limited to 0.15% of the Government & Agency Securities
Portfolio's average daily net assets.

Effective June 1, 2008, the Advisor has agreed to contractually reduce its
management fee for the Government & Agency Securities Portfolio such
that the annual effective rate is limited to 0.05% of the Government &
Agency Securities Portfolio's average daily net assets.

Accordingly, for the year ended April 30, 2009, the Advisor waived a
portion of its management fee on the Government & Agency Securities
Portfolio aggregating $707,785 and the amount charged aggregated
$6,321,775.

Accordingly, for the year ended April 30, 2009, the Portfolios incurred
management fees equivalent to the following annual effective rates of
each Portfolio's average daily net assets:

|Portfolio                                | Annual
Effective Rate
|---------------------------------------- | ---------------------
|Money Market Portfolio                   | .16%                 
|Government & Agency Securities Portfolio | .05%                 
|Tax-Exempt Portfolio                     | .06%                 

For the period from May 1, 2007 through July 31, 2009, the Advisor had
contractually agreed to waive or reimburse certain operating expenses in
order to maintain the annual expenses at 0.85% of the Davidson Cash
Equivalent Shares of the Tax-Exempt Portfolio (excluding certain expenses
such as extraordinary expenses, taxes, brokerage and interest).

For the period from May 1, 2008 through April 30, 2009, the Advisor
voluntarily agreed to waive or reimburse certain operating expenses in
order to maintain the annual expenses at 1.00% and 1.00% of the
Davidson Cash Equivalent Shares of the Money Market Portfolio and
Government & Agency Securities Portfolio, respectively (excluding certain
expenses such as extraordinary expenses, taxes, brokerage and interest).

For the period from May 1, 2008 through April 30, 2009, the Advisor
voluntarily agreed to waive or reimburse certain operating expenses in
order to maintain the annual expenses at 0.85% and 0.85% of the
Davidson Cash Equivalent Plus Shares of the Money Market Portfolio and
Government & Agency Securities Portfolio, respectively (excluding certain
expenses such as extraordinary expenses, taxes, brokerage and interest).

The Advisor also has agreed to maintain expenses of certain other classes
of the Trust. These rates are disclosed in the respective share classes'
annual reports that are provided separately and are available upon request.

In addition, the Advisor has agreed to voluntarily waive expenses as
necessary to maintain a minimum yield. The waiver may be changed or
terminated at any time without notice. Under these arrangements, the
Advisor waived certain distribution fees on Davidson Cash Equivalent
Shares for Money Market Portfolio, Government & Agency Securities
Portfolio and Tax-Exempt Portfolio and Davidson Cash Equivalent Plus
Shares for Money Market Portfolio and Government & Agency Securities
Portfolio.

Administration Fee. Effective June 1, 2008, the Government & Agency
Securities Portfolio and the Tax-Exempt Portfolio entered into an
Administrative Services Agreement with DIMA, pursuant to which DIMA
provides most administrative services to the Government & Agency
Securities Portfolio and the Tax-Exempt Portfolio. For all services provided
under the Administrative Services Agreement, each of these two
Portfolios pays the Advisor an annual fee ("Administration Fee") of 0.10%
of each of these two Portfolios' average daily net assets, computed and
accrued daily and payable monthly. For the period from June 1, 2008
through April 30, 2009, the Administration Fee from the Government &
Agency Securities Portfolio and the Tax-Exempt Portfolio was as follows:

|Portfolio                                | Administration
Fee | Unpaid at

Service Provider Fees. DWS Investments Service Company ("DISC"), an
affiliate of the Advisor, is the transfer agent, dividend-paying agent and
shareholder service agent for the Portfolios. Pursuant to a sub-transfer
agency agreement between DISC and DST Systems, Inc. ("DST"), DISC
has delegated certain transfer agent, dividend-paying agent and
shareholder service agent functions to DST. DISC compensates DST out
of the shareholder servicing fee it receives from the Portfolios. For the
year ended April 30, 2009, the amounts charged to the Portfolios by DISC

affiliated with the Advisor retainer fees plus specified amounts for various
committee services and for the Board Chairperson.

3. Fee Reductions

Each Portfolio has entered into an arrangement with its custodian and
transfer agent whereby credits realized as a result of uninvested cash
balances are used to reduce a portion of each Portfolio's custodian
expenses. During the year ended April 30, 2009, each Portfolio's custodian
fee was reduced as follows:

|Portfolio                                | Custody Credits | Transfer Agent

4. Line of Credit

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

5. Share Transactions

The following table summarizes share and dollar activity in the Portfolios:

6. Participation in the Treasury's Temporary Guarantee Program

The Portfolios are participating in the Temporary Guarantee Program for
Money Market Funds (the "Program") established by the U.S.
Department of the Treasury (the "Treasury").

The Program is designed to protect the value of accounts in each Portfolio
as of the close of business on September 19, 2008. According to the
terms of the Program, any investment made by a shareholder after
September 19, 2008 in excess of the amount held in the account as of
the close of business on that date will not be covered by the Program.
Any purchase of the shares of the Portfolios for an account opened after
September 19, 2008 will also not be covered under the Program. The
Program guarantee will apply to the lesser of (i) the number of shares held
in an account as of the close of business on September 19, 2008, or
(ii) the number of shares held in the account on the date the Program
guarantee is triggered. Subject to certain conditions and limitations, the
Program guarantee is triggered if the Portfolios' net asset value falls
below $0.995 and the Portfolios are liquidated. Guarantee payments under
the Program will not exceed the amount available within the Treasury's
Exchange Stabilization Fund ("ESF") on the date of payment.

Each Portfolio will bear the expenses of participating in the Program. The
expense is determined by the product of (i) the number of shares
outstanding of each class as of September 19, 2008 valued at $1.00; and
(ii) the applicable Program participation fee rate, which is based upon the
market-based net asset value outstanding of each share class as of
September 19, 2008. For the initial period ending December 18, 2008, the
Program participation fee was equal to 0.01%. For the coverage under the
Program beginning on December 19, 2008 and ending on April 30, 2009,
the Program participation fee was equal to 0.015%. For the coverage
under the Program beginning on May 1, 2009 and ending September 18,
2009, the Program participation fee is equal to 0.015%. This expense is
being amortized over the length of the participation in the Program and is
included in "Temporary guarantee program participation fee" on the
Statement of Operations. For the period through April 30, 2009, Money
Market Portfolio accrued $1,179,399, Government & Agency Securities
Portfolio accrued $3,104,681 and Tax-Exempt Portfolio accrued $1,017,974.
The Program is set to terminate on September 18, 2009.

Neither the Portfolios nor Deutsche Investment Management Americas
Inc., the Portfolios' investment advisor, are in any manner approved,
endorsed, sponsored or authorized by the Treasury.

Report of Independent Registered Public
Accounting Firm

To the Shareholders and Board of Trustees of Cash Account Trust:

We have audited the accompanying statements of assets and liabilities,
including the investment portfolios, of Cash Account Trust (the "Trust")
(comprising the Money Market Portfolio, Government & Agency Securities
Portfolio and Tax-Exempt Portfolio) (collectively, the "Portfolios"), as of
April 30, 2009, and the related statements of operations for the year then
ended, the statements of changes in net assets for each of the two years
in the period then ended, and the financial highlights for each of the
periods indicated therein. These financial statements and financial
highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements and financial highlights are free of
material misstatement. We were not engaged to perform an audit of the
Trust's internal control over financial reporting. Our audits included
consideration of internal control over financial reporting as a basis for
designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
Trust's internal control over financial reporting. Accordingly, we express no
such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements and
financial highlights, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of April 30, 2009, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. We believe that our audits provide
a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Portfolios of Cash Account Trust at April 30, 2009, the results of their
operations for the year then ended, the changes in their net assets for
each of the two years in the period then ended, and the financial
highlights for each of the periods indicated therein, in conformity with U.S.
generally accepted accounting principles.

Summary of Management Fee Evaluation
by Independent Fee Consultant

October 24, 2008

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

Qualifications

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

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

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

Evaluation of Fees for each DWS Fund

My work focused primarily on evaluating, fund-by-fund, the fees charged
to each of the 129 Fund portfolios in the DWS Fund family. For each Fund,
I considered each of the key factors mentioned above, as well as any
other relevant information. In doing so I worked closely with the Funds'
Independent Directors in their annual contract renewal process, as well as
in their approval of contracts for several new funds (documented
separately).

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

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

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

Fees and Expenses Compared with Other Funds

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

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

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

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

DeAM's Fees for Similar Services to Others

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

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

Costs and Profit Margins

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

Economies of Scale

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

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

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

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

Quality of Service  Performance

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

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

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

Complex-Level Considerations

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

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

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

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

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

Findings

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

Summary of Administrative Fee Evaluation
by Independent Fee Consultant

September 29, 2008

Pursuant to an Order entered into by Deutsche Asset Management
(DeAM) with the Attorney General of New York, I, Thomas H. Mack, have
been appointed the Independent Fee Consultant for the DWS Funds and
have as part of my duties evaluated the reasonableness of the proposed
management fees to be charged by DeAM to the DWS Funds, taking onto
account a proposal to pass through to the funds certain fund
accounting-related charges in connection with new regulatory
requirements. My evaluation considered the following:

•    While the proposal would alter the services to be provided under the
Administration Agreement, which I consider to be part of fund
management under the Order, it is my opinion that the change in
services is slight and that the scope of prospective services under the
combination of the Advisory and Administration Agreements continues
to be comparable with those typically provided to competitive funds
under their management agreements.

•    While the proposal would increase fund expenses, according to a pro
forma analysis performed by management, the prospective effect is
less than .01% for all but seven of the DeAM Funds' 438 active share
classes, and in all cases the effect is less than .03% and overall
expenses would remain reasonable in my opinion.

Based on the foregoing considerations, in my opinion the fees and
expenses for all of the DWS Funds will remain reasonable if the Directors
adopt this proposal.

ITEM 2.
        CODE OF ETHICSAs of the end of the period, April 30, 2009, Cash Account Trust has 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 EXPERTThe Funds audit committee is comprised solely of trustees who are independent (as such term has been defined by the Securities and Exchange Commission (SEC) in regulations implementing Section 407 of the Sarbanes-Oxley Act (the Regulations)). The Funds Board of Trustees has determined that there are several audit committee financial experts (as such term has been defined by the Regulations) serving on the Funds audit committee including Mr. William McClayton, the chair of the Funds audit committee.  The SEC has stated that an audit committee financial expert is not an expert for any purpose, including for purposes of Section 11 of the Securities Act of 1933 and the designation or identification of a person as an audit committee
financial expert pursuant to this Item 3 of Form N-CSR does not impose on such person any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification.ITEM 4.

   All other engagement fees were billed for services in connection with internal control reviews, agreed upon procedures and tax compliance for DIMA and other related entities that provide support for the operations of the Fund.  Audit Committee Pre-Approval Policies and Procedures.  Generally, each Funds Audit Committee must pre approve (i) all services to be performed for a Fund by a Funds Independent Registered Public Accounting Firm and (ii) all non-audit services to be performed by a Funds Independent Registered Public Accounting Firm for the DIMA Entities with respect to operations and financial reporting of the Fund, except that the Chairperson or Vice Chairperson of each Funds Audit Committee may grant the pre-approval for non-audit services described in items (i) and (ii) above for non-prohibited services for engagements of less than $100,000.  All such delegated pre approvals shall be presented to each Funds Audit Committee no later than the next Audit Committee meeting.  There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception under Rule 2-01 of Regulation S-X.  According to the registrants principal Independent Registered Public Accounting Firm, all of the principal Independent Registered Public Accounting Firm's hours spent on auditing the registrant's financial statements were attributed to work performed by full-time permanent employees of the principal Independent Registered Public Accounting Firm.  *** E&Y advised the Funds Audit Committee that E&Y had identified four matters that it determined to be inconsistent with the SECs auditor independence rules.  First, E&Y advised the Funds Audit Committee that, in 2006 and 2007, Deutsche Bank AG (DB) provided standard overdraft protection on a depository account and a guarantee of certain lease deposits to the E&Y member firm in Germany (E&Y Germany).  DB is within the Investment Company Complex (as defined by SEC rules) and therefore covered by the SEC auditor independence rules applicable to the Fund. E&Y advised the Audit Committee that while neither of these arrangements was ever utilized by E&Y Germany, they could constitute lending type arrangements in violation of Rule 2-01 of Regulation S-X. (Rule 2-01(c)(1)(ii)(A) provides that an accountant is not independent when an accounting firm has a loan to or from an audit client.) E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching
 this conclusion, E&Y noted a number of factors, including that neither of the arrangements was ever utilized and, accordingly, E&Y Germany never had amounts outstanding to DB, these arrangements were immaterial to E&Y Germany and DB and the E&Y professionals responsible for the Funds audits were not aware of these arrangements. E&Y informed the Audit Committee that E&Y Germany has cancelled the overdraft arrangement and has terminated the guarantee on the lease deposits.  Second, E&Y advised the Funds Audit Committee that, in 2007 and 2008, DB provided standard overdraft protection on a depository account to the E&Y member firm in India (E&Y India).  E&Y advised the Audit Committee that E&Y India utilized this arrangement twice in 2007; therefore, the arrangement constituted a lending type arrangement in violation of Rule 2-01(c)(1)(ii)(A) of Regulation S-X as described above.  E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching this conclusion, E&Y noted a number of factors,including that the arrangement did not create a mutual or conflicting interest between E&Y and the Fund and that the arrangement did not involve the Fund, but rather affiliates of the Fund in the Investment Company
Complex.  E&Y informed the Audit Committee that E&Y India has cancelled the overdraft arrangement.  Third, E&Y advised the Funds Audit Committee that, in 2008, an E&Y professional purchased interests in a fund sponsored by a subsidiary of Deutsche Bank AG that is not audited by E&Y.  Subsequent to the purchase, the E&Y professional became a Covered Person (as defined by SEC rules) of the Fund as a result of providing non-audit services to a DB entity within the Investment Company Complex.  E&Y informed the Audit Committee that this investment constituted an investment in an affiliate of an audit client in violation of the Rule 2-01(c)(1) of Regulation S-X.  E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching this conclusion, E&Y noted a number of factors, including thatthe E&Y professional did not have any financial interest in the
Fund and was not involved with the provision of audit services to the Fund.  E&Y informed the Audit Committee that the E&Y professional no longer provides any services to any entity within the Investment Company Complex and is no longer deemed to be a Covered Person with respect to the Fund.  Finally, E&Y advised the Funds Audit Committee that, in 2008, an E&Y professional whose spouse owned interests in two DWS Funds that are not audited by E&Y, became a Covered Person of the Fund as a result of providing attest services to a DB entity within the Investment Company Complex.  E&Y informed the Audit Committee that this investment constituted an investment in an affiliate of an audit client in violation of the Rule 2-01(c)(1) of Regulation S-X.  E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching this conclusion, E&Y noted a number of factors, including thatthe E&Y professional did not have any financial interest in the Fund and was not involved with the provision of audit services to the Fund.  E&Y informed the Audit
Committee that the E&Y professional no longer provides any services to any entity within the Investment Company Complex and is no longer deemed to be a Covered Person with respect to the Fund. .

E&Y advised the Audit Committee that while neither of these arrangements was ever utilized by E&Y Germany, they could constitute lending type arrangements in violation of Rule 2-01 of Regulation S-X. (Rule 2-01(c)(1)(ii)(A) provides that an accountant is not independent when an accounting firm has a loan to or from an audit client.) E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching
 this conclusion, E&Y noted a number of factors, including that neither of the arrangements was ever utilized and, accordingly, E&Y Germany never had amounts outstanding to DB, these arrangements were immaterial to E&Y Germany and DB and the E&Y professionals responsible for the Funds audits were not aware of these arrangements. E&Y informed the Audit Committee that E&Y Germany has cancelled the overdraft arrangement and has terminated the guarantee on the lease deposits.  Second, E&Y advised the Funds Audit Committee that, in 2007 and 2008, DB provided standard overdraft protection on a depository account to the E&Y member firm in India (E&Y India).  E&Y advised the Audit Committee that E&Y India utilized this arrangement twice in 2007; therefore, the arrangement constituted a lending type arrangement in violation of Rule 2-01(c)(1)(ii)(A) of Regulation S-X as described above.  E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching this conclusion, E&Y noted a number of factors,including that the arrangement did not create a mutual or conflicting interest between E&Y and the Fund and that the arrangement did not involve the Fund, but rather affiliates of the Fund in the Investment Company
Complex.  E&Y informed the Audit Committee that E&Y India has cancelled the overdraft arrangement.  Third, E&Y advised the Funds Audit Committee that, in 2008, an E&Y professional purchased interests in a fund sponsored by a subsidiary of Deutsche Bank AG that is not audited by E&Y.  Subsequent to the purchase, the E&Y professional became a Covered Person (as defined by SEC rules) of the Fund as a result of providing non-audit services to a DB entity within the Investment Company Complex.  E&Y informed the Audit Committee that this investment constituted an investment in an affiliate of an audit client in violation of the Rule 2-01(c)(1) of Regulation S-X.  E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching this conclusion, E&Y noted a number of factors, including thatthe E&Y professional did not have any financial interest in the
Fund and was not involved with the provision of audit services to the Fund.  E&Y informed the Audit Committee that the E&Y professional no longer provides any services to any entity within the Investment Company Complex and is no longer deemed to be a Covered Person with respect to the Fund.  Finally, E&Y advised the Funds Audit Committee that, in 2008, an E&Y professional whose spouse owned interests in two DWS Funds that are not audited by E&Y, became a Covered Person of the Fund as a result of providing attest services to a DB entity within the Investment Company Complex.  E&Y informed the Audit Committee that this investment constituted an investment in an affiliate of an audit client in violation of the Rule 2-01(c)(1) of Regulation S-X.  E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching this conclusion, E&Y noted a number of factors, including thatthe E&Y professional did not have any financial interest in the Fund and was not involved with the provision of audit services to the Fund.  E&Y informed the Audit
Committee that the E&Y professional no longer provides any services to any entity within the Investment Company Complex and is no longer deemed to be a Covered Person with respect to the Fund. .   ITEM 5.
