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

Although inflation-indexed bonds are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in the fund's value. If interest rates rise due to reasons other than inflation, the fund's investment in these securities may not be protected to the extent that the increase is not reflected in the bond's inflation measure. Moreover, if the fund purchases            inflation-indexed bonds offered by foreign issuers, the rate of inflation measured by the foreign index may not be correlated to the rate of inflation in the US. The fund is subject to interest rate risk, which means that the value of inflation-indexed bonds and other fixed income securities held by the fund generally will decline as interest rates rise. The full faith and credit guarantee of the US government, which attaches to certain securities that the fund invests in, does not            protect the fund against interest rate risk. The fund invests in derivatives seeking to hedge positions in certain securities and to generate income in order to enhance the fund's returns. Derivatives can be more volatile and less liquid than traditional fixed-income securities. There can be no assurance that the fund will meet its objective or that any strategy employed by the fund will be successful. Please see the prospectus for specific details regarding the fund's risk            profile.

**Performance SummarySeptember 30, 2008**

**Classes A, B, C and Institutional**

**All performance shown is historical, assumes reinvestment of all dividend and capital gain distributions, and does not guarantee future results. Investment return and principal value fluctuate with changing market conditions so that, when redeemed, shares may be worth more or less than their original cost. Current performance may be lower or higher than the performance quoted. Please visit www.dws-investments.com            for the Fund's most recent month-end performance.**

**The maximum sales charge for Class A shares is 2.75%. For Class B shares, the maximum contingent deferred sales charge (CDSC) is 4% within the first year after purchase, declining to 0% after six years. Class C shares have no front-end sales charge but redemptions within one year of purchase may be subject to a CDSC of 1%. Unadjusted returns do not reflect sales charges and would have been lower if they had.            Institutional Class shares are not subject to sales charges.**

**The total annual fund operating expense ratios, gross of any fee waivers or expense reimbursements, as stated in the fee table of the prospectus dated February 1, 2008 are 1.74%, 2.51%, 2.39% and 1.29% for Class A, Class B, Class C and Institutional Class shares, respectively. Please see the Information About Your Fund's Expenses, the Financial Highlights and Notes to the Financial Statements (Note C, Related            Parties) sections of this report for gross and net expense related disclosure for the period ended September 30, 2008.**

**To discourage short-term trading, the Fund imposes a 2% redemption fee on shareholders redeeming shares held less than 15 days, which has the effect of lowering total return.**

Returns and rankings during all periods shown reflect a fee waiver and/or expense reimbursement. Without this waiver/reimbursement, returns would have been lower.

Performance figures do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Returns and rankings may differ by share class.

**Information About Your Fund's Expenses**

As an investor of the Fund, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and account maintenance fees, which are not shown in this section. The following tables are intended to help you understand your ongoing expenses (in            dollars) of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. In the most recent six-month period, the Fund limited these expenses; had they not done so, expenses would have been higher. The example in the table is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period(April 1, 2008 to September 30, 2008).

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

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

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

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expense of owning different funds. An account maintenance fee of $6.25 per quarter for Class S shares may apply for certain accounts whose            balances do not meet the applicable minimum initial investment. This fee is not included in these tables. If it was, the estimate of expenses paid for Class S shares during the period would be higher, and account value during the period would be lower, by this amount.

**Q: How did DWS Inflation Protected Plus Fund perform during the annual period?**

**A:**The fund's Class A shares produced a total return of 3.94% for the 12 months ended September 30, 2008. (Returns are unadjusted for sales charges. If sales charges had been included, returns would have been lower. Past performance is no guarantee of future results. Please see pages 4 through 9 for the performance            of other share classes and more complete performance information.) The fund's benchmark, the Barclays Capital US Treasury: US TIPS Index, produced a total return of 6.20% for the same period.1 The average return for the Lipper TIPS Funds category for the 12 months was 3.95%.2

**Q: Please describe the market environment for the fund over the 12-month period.**

**A:**For the period, government-backed bonds including US Treasuries and GNMAs outperformed other sectors of the bond market, driven by a flight to quality on the part of investors.

As the period began, ongoing disclosures of subprime-related losses at leading financial companies continued to drive a market demand for liquidity. Financial institutions that had issued short-term commercial paper to finance lower-quality or longer-maturity holdings in special investment vehicles were unable to roll over their debt in the prevailing credit crunch. As a result, many were forced to unwind credit positions under            duress, causing the performance of fixed-income instruments that trade at a yield spread versus Treasuries to suffer in relation to Treasuries.3 Credit rating downgrades of major firms that insure bond issues exacerbated the widening of yield spreads, and already wary market participants became increasingly reluctant to assume the risk that counterparties to trades would be able to deliver as promised.4

In March, leading investment bank Bear Stearns fell victim to the liquidity crisis, leading the US Federal Reserve Board (the Fed) to take aggressive action to provide sources of funding and stabilize the markets. This proved something of a turning point as credit spreads narrowed for a time. However, by June skyrocketing oil prices and a weakening economy had undercut whatever positive sentiment the Fed            had generated.

The ongoing credit market distress would reach new levels of visibility in September. First, Fannie Mae and Freddie Mac, who together own or guarantee roughly half of the US mortgage market, were taken over by the government. In mid-September, leading investment bank Lehman Brothers failed while global insurance conglomerate AIG was bailed out by the US Treasury. This was followed shortly by the conversion of Morgan Stanley and            Goldman Sachs to bank holding companies as they sought shelter from the credit market storm, and the FDIC seizure and sale to JPMorgan Chase of giant thrift Washington Mutual. The net result was an evaporation of liquidity as the credit markets seized in September. As these events unfolded, the Bush administration sought approval of a mammoth rescue package designed to unfreeze credit markets by funding the removal of illiquid mortgage-related debt from the balance sheets of major            financial institutions.

During the period, the Fed lowered the federal funds rate by 275 basis points (2.75 percentage points) to 2% over the course of several moves as it sought to add liquidity. During the 12 months we saw extraordinary interest rate volatility. For the full period, however, Treasury yields finished lower and the Treasury yield curve steepened as declines on the short end were the most significant. To            illustrate, the two-year Treasury yield fell by 205 basis points, from 4.01% to 1.96%, while the 10-year fell 78 basis points, from 4.60% to 3.82%, resulting in the yield curve becoming steeper by 127 basis points (100 basis points equals one percentage point).

**Q: Can you review inflation-indexed bonds and how they work?**

**A:**An inflation-indexed bond is a special type of fixed-income security that is structured to provide protection against inflation. The most common example of such a security in the United States is the Treasury Inflation Protected Security (TIPS). With TIPS, both the value of the interest income and principal paid on the security is adjusted to track changes in the Urban Consumer            Price Index (CPI-U) or a comparable inflation index. Interest income paid on the security is applied to the inflation-adjusted principal rather than the security's original face value.

As a result, during periods of inflation, every interest payment on a TIPS will be greater than the one before it. In periods of deflation, the opposite will be true. When TIPS mature, investors receive the greater of either the inflation-adjusted principal or the original face value. It is important to note, however, that not all inflation-indexed bonds provide the guarantee of original face value of the bond.

To better understand inflation-indexed securities, consider the example in the accompanying box.
| Suppose $1,000 is invested in a 10-year inflation-indexed bond with a 4% coupon rate.

If inflation is 3% during the following year, the face value would be adjusted to $1,030 and the annual interest payment would be $41.20 (4% of $1,030).

If inflation is 3% again the following year, the principal would be adjusted to $1,060.90 ($1,030 x 1.03) and the interest payment would be $42.44 (4% of $1,060.90).

If there was 3% deflation in the third year, the face value would be adjusted downward to $1,029.07 ($1,060.90 x 0.97). |

**Q: Can you review how you managed the fund and what helped or hurt performance?**

**A:**The fund's core portfolio has been invested almost entirely in TIPS, i.e., Treasury-based inflation protected securities. Over the first half of the annual period, inflation concerns driven in large part by rising prices for oil and other commodities led to strong performance for the TIPS market and the fund. However, the majority of these gains were erased in the economic turmoil            toward the end of the period, as growth and inflation expectations fell sharply.

In general, we strive to maintain a neutral duration (interest rate sensitivity relative to the index) with the fund's TIPS holdings, as we believe that more value can be added through security selection and our global asset allocation overlay strategy than by guessing the direction of interest rates.5 In doing so, we hold a subset of securities meant to track or slightly outperform the Barclays Capital US Treasury            TIPS Index. We seek to approximate the yield curve exposure of the index by holding representative securities across the maturity spectrum. Performance of this core TIPS exposure lagged the index somewhat, as market conditions made it difficult for the fund to maintain balanced exposure across the yield curve.

Some other funds that seek to provide inflation protection include exposure to commodities or real estate-related holdings, which will of course influence the returns they provide. The fund had no exposure in these areas, which constrained returns early but helped as prices for oil and other commodities plummeted late in the period.

As part of our approach, we seek to enhance total returns by employing a global tactical asset allocation strategy. This strategy, which DWS Investments calls iGAP (integrated Global Alpha Platform) seeks to identify the relative value to be found among global bond and currency markets, and then to benefit from disparities through the use of fixed-income futures and currency forward contracts. For the 12 months, the alpha            strategy detracted modestly from the fund's return. The strategy's position in fixed-income futures added value, but this was more than offset by the negative performance from the currency position.

**Q: What is your overall view of the investment environment for TIPS?**

**A:**With the collapse in mortgages, and with the room to maneuver provided by the recent decline in prices for oil and other commodities, the prospect is for interest rate cuts in the near term as the Fed seeks to make it easier for homeowners to refinance. Even with a loosening in monetary policy, we believe the outlook is most likely for continued weakening of the economy and low            inflation. At the end of September, the TIPS market was pricing in an inflation expectation of about 1%, resulting in a reasonably attractive valuation under most likely scenarios.

Given the market's recent preference for Treasury securities, we continue to evaluate opportunities in areas that are less fully priced, including high-quality corporate inflation-indexed securities. For those concerned about the possible future impact of inflation on both stocks and traditional fixed-income securities, we believe our fund continues to offer a compelling diversification opportunity. We will continue to closely            monitor economic conditions as we seek to provide maximum inflation-adjusted return, consistent with preservation of capital.

**Notes to Financial Statements**

**A. Significant Accounting Policies**

DWS Inflation Protected Plus Fund (the "Fund") is a diversified series of DWS Institutional 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 Fund offers multiple classes of shares which provide investors with different purchase options. Class A shares are offered to investors subject to an initial sales charge. Class B shares are offered to investors without an initial sales charge but are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions. Class B shares automatically convert to            Class A shares six years after issuance. Class C shares are offered to investors without an initial sales charge and are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions within one year of purchase. Class C shares do not convert into another class. Institutional Class shares are offered to a limited group of investors, are not subject to initial or contingent deferred sales charges and have lower            ongoing expenses than other classes. Class S shares are not subject to initial or contingent deferred sales charges and are generally not available to new investors except under certain circumstances.

Investment income, realized and unrealized gains and losses, and certain fund-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, 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 Fund have equal rights with respect to voting subject to class-specific arrangements.

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

**Security Valuation.** Investments are stated at value determined as of the close of regular trading on the New York Stock Exchange on each day the exchange is open for trading. Debt securities are valued by independent pricing services approved by the Trustees of the Fund. If the pricing services are unable to provide valuations, securities are valued at the most recent bid quotation or evaluated            price, as applicable, obtained from a broker-dealer. Such services may use various pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as broker quotes.

Money market instruments purchased with an original or remaining maturity of sixty days or less, maturing at par, are valued at amortized cost. Investments in open-end investment companies and Cash Management QP Trust are valued at their net asset value each business day.

Securities and other assets for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued in a manner that is intended to reflect their fair value as determined in accordance with procedures approved by the Trustees.

**New Accounting Pronouncements.** In September 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"). FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. FAS 157 is effective for fiscal years beginning after November 15,            2007. As of September 30, 2008, management does not believe the adoption of FAS 157 will impact the amounts reported in the financial statements, however, additional disclosures will be required about the levels of inputs used to develop the measurements of fair value and the effect of certain of the measurements reported in the statement of operations for a fiscal period.

In addition, in March 2008, the FASB issued Statement of Financial Accounting Standards No. 161 ("FAS 161"), "Disclosures about Derivative Instruments and Hedging Activities". FAS 161 requires enhanced disclosure about an entity's derivative and hedging activities including qualitative disclosures about the objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on            derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. FAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008. Management is currently reviewing the enhanced disclosure requirements for the adoption of FAS 161.

**Foreign Currency Translations.** The books and records of the Fund are maintained in US dollars. Investment securities and other assets and liabilities denominated in a foreign currency are translated into US dollars at the prevailing exchange rates at period end. Purchases and sales of investment securities, income and expenses are translated into US dollars at the prevailing exchange rates on the            respective dates of the transactions.

Net realized and unrealized gains and losses on foreign currency transactions represent net gains and losses between trade and settlement dates on securities transactions, the disposition of forward foreign currency exchange contracts and foreign currencies and the difference between the amount of net investment income accrued and the US dollar amount actually received. That portion of both realized and unrealized gains and            losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed but is included with net realized and unrealized gain/appreciation and loss/depreciation on investments.

**Forward Foreign Currency Exchange Contracts.** A forward foreign currency exchange contract ("forward currency contract") is a commitment to purchase or sell a foreign currency at the settlement date at a negotiated rate. The Fund may engage in forward currency contracts as part of its global tactical asset allocation overlay strategy.

Forward currency contracts are valued at the prevailing forward exchange rate of the underlying currencies and unrealized gain (loss) is recorded daily. Sales and purchases of forward currency contracts having the same settlement date and broker are offset and any gain (loss) is realized on the date of offset; otherwise, gain (loss) is realized on settlement date. Realized and unrealized gains and losses which represent the            difference between the value of a forward currency contract to buy and a forward currency contract to sell are included in net realized and unrealized gain (loss) from foreign currency.

Certain risks may arise upon entering into forward currency contracts from the potential inability of counterparties to meet the terms of their contracts.

**Securities Lending.** The Fund may lend securities to financial institutions. The Fund retains beneficial ownership of the securities it has loaned and continues to receive interest and dividends paid by the issuer of securities and to participate in any changes in their value. The Fund requires the borrowers of the securities to maintain collateral with the Fund consisting of liquid, unencumbered            assets having a value at least equal to the value of the securities loaned. When the collateral falls below specified amounts, the lending agents will use their best efforts to obtain additional collateral on the next business day to meet required amounts under the security lending agreement. The Fund may invest the cash collateral into a joint trading account in an affiliated money market fund pursuant to Exemptive Orders issued by the SEC. The Fund receives compensation for            lending its securities either in the form of fees or by earning interest on invested cash collateral net of borrower rebates and fees paid to the lending agent. Either the Fund or the borrower may terminate the loan. There may be risks of delay and costs in recovery of securities or even loss of rights in the collateral should the borrower of the securities fail financially. The Fund is also subject to all investment risks associated with the value of any cash collateral            received, including, but not limited to, interest rate, credit and liquidity risk associated with such investments.

**Inflation-Indexe****dInstruments.**Inflation-indexed instruments are fixed income securities whose principal value is periodically adjusted to the rate of inflation. The interest rate on these instruments is generally fixed at issuance at a rate lower than typical bonds or notes. Over the            life of an inflation-indexed instrument, however, interest will be paid based on a principal value, which is adjusted for any inflation or deflation. Any increase or decrease in the principal amount of an inflation-indexed instrument will result in an adjustment of interest income which is distributed to shareholders annually. Investors will receive their inflation-adjusted principal at maturity.

**Futures Contracts.** A futures contract is an agreement between a buyer or seller and an established futures exchange or its clearinghouse in which the buyer or seller agrees to take or make a delivery of a specific amount of a financial instrument at a specified price on a specific date (settlement date). The Fund may utilize futures contracts as an efficient means of managing            allocation between asset classes or to keep cash on hand to meet shareholder redemptions or other needs while maintaining exposure to the market. The Fund may also utilize futures as part of its global tactical overlay strategy.

Upon entering into a futures contract, the Fund is required to deposit with a financial intermediary an amount ("initial margin") equal to a certain percentage of the face value indicated in the futures contract. Subsequent payments ("variation margin") are made or received by the Fund dependent upon the daily fluctuations in the value of the underlying security and are recorded for financial reporting purposes as unrealized            gains or losses by the Fund. When entering into a closing transaction, the Fund will realize a gain or loss equal to the difference between the value of the futures contract to sell and the futures contract to buy. Futures contracts are valued at the most recent settlement price.

Certain risks may arise upon entering into futures contracts, including the risk that an illiquid secondary market will limit the Fund's ability to close out a futures contract prior to the settlement date and that a change in the value of a futures contract may not correlate exactly with the changes in the value of the securities or currencies hedged.

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

During the year ended September 30, 2008, the Fund utilized $723,000 of prior year capital loss carryforward.

The Fund has reviewed the tax positions for each of the three open tax years as of September 30, 2008 and has determined that no provision for income tax is required in the Fund's financial statements. Each of the Fund's federal tax returns for the prior three fiscal years remains subject to examination by the Internal Revenue Service.

**Distribution of Income and Gains.** Distributions are declared daily and distributed to shareholders monthly from net investment income. Net realized gains from investment transactions, in excess of available capital loss carryforwards, would be taxable to the Fund if not distributed, and, therefore, will be distributed to shareholders at least annually.

The timing and characterization of certain income and capital gains distributions are determined annually in accordance with federal tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences primarily relate to investments in futures, forward currency contracts and certain securities sold at a loss. As a result, net investment income (loss) and net realized            gain (loss) on investment transactions for a reporting period may differ significantly from distributions during such period. Accordingly, the Fund may periodically make reclassifications among certain of its capital accounts without impacting the net asset value of the Fund.

At September 30, 2008, the Fund's components of distributable earnings (accumulated losses) on a tax-basis were as follows:
| Undistributed ordinary income*                            | $ 6,551,406    |
|-----------------------------------------------------------|----------------|
| Undistributed long-term capital gains                     | $ 791,892      |
| Net unrealized appreciation (depreciation) on investments | $ (10,791,266) |

In addition, the tax character of distributions paid to shareholders by the Fund is summarized as follows:
|                                       | **Years Ended September 30,** |
|--------------------------------------------|-------------------------------|
|                                       | **2008**                      | **2007** |
| Distributions from ordinary income*        | $ 2,212,637                   | $ 1,415,547 |
| Distributions from long-term capital gains | $ —                     | $ 19,673 |

**Redemption Fees.** The Fund imposes a redemption fee of 2% of the total redemption amount on the Fund shares redeemed or exchanged within 15 days of buying them, either by purchase or exchange. This fee is assessed and retained by the Fund for the benefit of the remaining shareholders. The redemption fee is accounted for as an addition to paid-in-capital.

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

**Expenses.** Expenses of the Trust arising in connection with a specificseries of the Trust, including the Fund,are allocated to thatseries. Other Trust expenses which cannot be directly attributed to a Fund are apportioned among theseriesin the            Trustincluding the Fund.

**Other.** Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. 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.

**B. Purchases and Sales of Securities**

During the year ended September 30, 2008, purchases and sales of investment securities (excluding short-term investments) aggregated $239,046,772 and $99,744,674, respectively.

**C. Related Parties**

**Management Agreement.** Under the Investment Management Agreement with Deutsche Investment Management Americas Inc. ("DIMA" or the "Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG, the Advisor directs the investments of the Fund in accordance with its 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 the Fund.

Under the Investment Management Agreement with the Advisor, the Fund pays a monthly management fee based on the Fund's average daily net assets, computed and accrued daily and payable monthly, at the following annual rates:
| First $1.5 billion of the Fund's average daily net assets | .400% |
|-----------------------------------------------------------|-------|
| Next $500 million of such net assets                      | .375% |
| Next $1 billion of such net assets                        | .360% |
| Next $1 billion of such net assets                        | .345% |
| Next $1 billion of such net assets                        | .330% |
| Next $1 billion of such net assets                        | .315% |
| Over $6 billion of such net assets                        | .300% |

Effective October 1, 2007 through January 31, 2009, the Advisor has contractually agreed to waive all or a portion of its management fee and reimburse or pay certain operating expenses of the Fund (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest expenses) to the extent necessary to maintain the operating expenses of each class as follows:
| Class A             | .90%  |
|---------------------|-------|
| Class B             | 1.65% |
| Class C             | 1.65% |
| Class S             | .70%  |
| Institutional Class | .65%  |

Accordingly, for the year ended September 30, 2008, the Advisor waived portion of its fee pursuant to the management agreement aggregating $95,765 and the amount imposed aggregated $356,378, which was equivalent to an annual effective rate of 0.32% of the Fund's daily average net assets.

In addition, the Advisor reimbursed $275 of sub-record keeping expenses for the Institutional Class shares.

**Administration Fee.** Pursuant to an Administrative Services Agreement, DIMA provides most administrative services to the Fund. For all services provided under the Administrative Services Agreement, the Fund pays the Advisor an annual fee ("Administration fee") of 0.10% of the Fund's average daily net assets, computed and accrued daily and payable monthly. For the year ended            September 30, 2008, the Advisor received an Administration fee of $113,036, of which $14,909 is unpaid.

**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 Fund. Pursuant to a sub-transfer agency agreement between DISC and DST Systems, Inc. ("DST"), DISC has delegated certain transfer agent, dividend-paying agent and shareholder service agent functions to DST. DISC compensates            DST out of the shareholder servicing fee it receives from the Fund. For the year ended September 30, 2008, the amounts charged to the Fund by DISC were as follows:
| **Services to Shareholders** | **Total Aggregated** | **Waived**   | **Unpaid at September 30, 2008** |

**Distribution and Service Fees.** Under the Fund's Class B and Class C 12b-1 plan, DWS Investments Distributors, Inc. ("DIDI"), an affiliate of the Advisor, receives a fee ("Distribution Fee") of 0.75% of average daily net assets of each of Class B and C shares. In accordance with the Fund's Underwriting and Distribution Services Agreement, DIDI enters into related selling group agreements with various            firms at various rates for sales of Class B and C shares. For the year ended September 30, 2008, the Distribution Fee was as follows:
| **Distribution Fee** | **Total Aggregated** | **Unpaid at September 30, 2008** |
|----------------------|----------------------|----------------------------------|
| Class B              | 9,781                | 1,554                            |
| Class C              | 46,327               | 6,012                            |

In addition, DIDI provides information and administrative services for a fee ("Servicing Fee") to Class A, B and C shareholders at an annual rate of up to 0.25% of average daily net assets for each such class. DIDI in turn has various agreements with financial services firms that provide these services and pays these fees based upon the assets of shareholder accounts the firms service. For the year ended September 30, 2008, the            Service Fee was as follows:
| **Service Fee** | **Total Aggregated** | **Waived** | **Unpaid at September 30, 2008** | **Annual Effective Rate** |
|-----------------|----------------------|------------|----------------------------------|--------------------------------|
| Class A         | $ 35,931             | $ —  | $ 2,354                          | .19%                           |
| Class B         | 3,185                | 83         | 405                              | .24%                           |

**Underwriting Agreement and Contingent Deferred Sales Charge.** DIDI is the principal underwriter for the Fund. Underwriting commissions paid in connection with the distribution of Class A shares for the year ended September 30, 2008 aggregated $15,733.

In addition, DIDI receives any contingent deferred sales charge ("CDSC") from Class B share redemptions occurring within six years of purchase and Class C share redemptions occurring within one year of purchase. There is no such charge upon redemption of any share appreciation or reinvested dividends. The CDSC is based on declining rates ranging from 4% to 1% for Class B and 1% for Class C, of the value of the shares            redeemed. For the year ended September 30, 2008, the CDSC for Class B and Class C shares aggregated $2,518 and $1,694, respectively. A deferred sales charge of up to 0.85% is assessed on certain redemptions of Class A shares.

**Typesetting and Filing Service Fees.** Under an agreement with DIMA, DIMA is compensated for providing typesetting and certain regulatory filing services to the Fund. For the year ended September 30, 2008, the amount charged to the Fund by DIMA included in the Statement of Operations under "reports to shareholders" aggregated $38,433, of which $9,690 is unpaid.

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

In connection with the board consolidation on April 1, 2008, of the two DWS Funds Boards of Trustees, certain Independent Board Members retired prior to their normal retirement date, and received a one-time retirement benefit. DIMA has agreed to reimburse the Funds for the cost of this benefit. During the period ended September 30, 2008, the Fund paid its allocated portion of the retirement benefit of $459 to the non-continuing            Independent Board Members, and the Fund was reimbursed by DIMA for this payment.

**Cash Management QP Trust.** Pursuant to an Exemptive Order issued by the SEC, the Fund may invest in the Cash Management QP Trust (the "QP Trust") and other affiliated funds managed by the Advisor. The QP Trust seeks to provide as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. The QP Trust does not pay its Advisor a management            fee for the affiliated funds' investments in the QP Trust.

**D. Fee Reductions**

The Fund 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 the Fund's custodian expenses. During the year ended September 30, 2008, the Fund's custodian fee was reduced by $1,053 and $680, respectively, for custody and transfer agent credits earned.

**E. Line of Credit**

The Fund and other affiliated funds (the "Participants") share in a $490 million revolving credit facility provided by a syndication of banks. The Fund 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 the Federal Funds Rate plus 0.35 percent. The Fund may borrow up to a maximum of 33 percent of its net assets under the agreement.

**F. Ownership of the Fund**

As of September 30, 2008, the DWS Alternative Asset Allocation Plus Fund held 54% of the total shares outstanding of the Fund.

**G. Share Transactions**

**Report of Independent Registered Public Accounting Firm**

**To the Trustees of DWS Institutional Funds and the Shareholders of DWS Inflation Protected Plus Fund:**

In our opinion, the accompanying statement of assets and liabilities, including the investment portfolio, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of DWS Inflation Protected Plus Fund (the "Fund") at September 30, 2008, the results of its operations, the changes in its net assets and the financial            highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements 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 are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement            presentation. We believe that our audits, which included confirmation of securities at September 30, 2008 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

**Investment Management Agreement Approval**

The Board of Trustees, including the Independent Trustees, approved the renewal of your Fund's investment management agreement (the "Agreement") with Deutsche Investment Management Americas Inc. ("DIMA") in September 2008.

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

• At the present time, all but one of your Fund's Trustees are independent of DIMA and its affiliates.

• The Trustees meet frequently to discuss fund matters. Each year, the Trustees dedicate part or all of several meetings to contract review matters. Over the course of several months, the Board's Contract Committee, in coordination with the Board's Fixed Income and Quant Oversight Committee, reviewed comprehensive materials received from DIMA, independent third parties and independent counsel. These            materials included an analysis of the Fund's performance, fees and expenses, and profitability compiled by the Fund's independent fee consultant. The Board also received extensive information throughout the year regarding performance of the Fund.

• The Trustees regularly meet privately with their independent counsel (and, as needed, other advisors) to discuss contract review and other matters. In addition, the Trustees were also advised by the Fund's independent fee consultant in the course of their review of the Fund's contractual arrangements and considered a comprehensive report prepared by the independent fee consultant in connection with            their deliberations (the "IFC Report").

• In connection with reviewing the Agreement, the Board also reviewed the terms of the Fund's Rule 12b-1 plan, distribution agreement, administrative services agreement, transfer agency agreement and other material service agreements.

• Based on its evaluation of the information provided, the Contract Committee presented its findings and recommendations to the Independent Trustees as a group. The Independent Trustees reviewed the Contract Committee's findings and recommendations and presented their recommendations to the full Board.

In connection with the contract review process, the Contract Committee and the Board considered the factors discussed below, among others. The Board also considered that DIMA and its predecessors have managed the Fund since its inception, and the Board believes that a long-term relationship with a capable, conscientious advisor is in the best interests of the Fund. The Board considered, generally, that shareholders chose to            invest or remain invested in the Fund knowing that DIMA managed the Fund, and that the Agreement was approved by the Fund's shareholders at a special meeting held in 2006. DIMA is part of Deutsche Bank, a major global banking institution that is engaged in a wide range of financial services. The Board believes that there are significant advantages to being part of a global asset management business that offers a wide range of investing expertise and resources, including hundreds of            portfolio managers and analysts with research capabilities in many countries throughout the world.

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

**Nature, Quality and Extent of Services.** The Board considered the terms of the Agreement, including the scope of advisory services provided under the Agreement. The Board noted that, under the Agreement, DIMA provides portfolio management services to the Fund and that, pursuant to a separate administrative services agreement, DIMA provides administrative services to the Fund. The Board            considered the experience and skills of senior management and investment personnel, the resources made available to such personnel, the ability of DIMA to attract and retain high-quality personnel, and the organizational depth and stability of DIMA. The Board reviewed the Fund's performance over short-term and long-term periods and compared those returns to various agreed-upon performance measures, including market indices and a peer universe compiled by the independent fee            consultant using information supplied by Lipper Inc. ("Lipper"). The Board also noted that it has put a process into place of identifying "Focus Funds" (e.g., funds performing poorly relative to their benchmark or a peer group compiled by Lipper), and receives more frequent reporting and information from DIMA regarding such funds, along with DIMA's remedial plans to address underperformance. The Board believes this process is an effective manner of identifying and addressing            underperforming funds. Based on the information provided, the Board noted that for the one-year period ended December 31, 2007, the Fund's performance (Class A shares) was in the 1st quartile of the applicable Lipper universe (the 1st quartile being the best performers and the 4th quartile being the worst performers). The Board also observed that the Fund has underperformed its benchmark in the one-year period ended December 31, 2007. The Board recognized that DIMA has made            significant changes in its investment personnel and processes in recent years in an effort to improve long-term performance.

On the basis of this evaluation and the ongoing review of investment results by the Board, the Board concluded that the nature, quality and extent of services provided by DIMA historically have been and continue to be satisfactory.

**Fees and Expenses.** The Board considered the Fund's investment management fee schedule, operating expenses and total expense ratios, and comparative information provided by Lipper and the independent fee consultant regarding investment management fee rates paid to other investment advisors by similar funds (1st quartile being the most favorable and 4th quartile being the least favorable). With            respect to management fees paid to other investment advisors by similar funds, the Board noted that the contractual fee rates paid by the Fund, which include a 0.10% fee paid to DIMA under the Fund's administrative services agreement, were lower than the median (2nd quartile) of the applicable Lipper peer group (based on Lipper data provided as of December 31, 2007). The Board noted that the Fund's Class A shares' total (net) operating expenses (excluding 12b-1 fees) were expected            to be higher than the median (4th quartile) of the applicable Lipper expense universe (based on Lipper data provided as of December 31, 2007, and analyzing Lipper expense universe Class A expenses less any applicable 12b-1 fees) ("Lipper Universe Expenses"). The Board also reviewed each other share class's total (net) operating expenses relative to the Lipper Universe Expenses. The Board considered the Fund's management fee rate as compared to fees charged by DIMA and certain            of its affiliates for comparable mutual funds and considered differences in fund and fee structures between the DWS Funds. The Board also considered how the Fund's total (net) operating expenses compared to the total (net) operating expenses of a more customized peer group selected by Lipper (based on such factors as asset size). The Board also noted that the expense limitations agreed to by DIMA helped to ensure that the Fund's total (net) operating expenses would be competitive            relative to the applicable Lipper universe.

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

**Profitability.** The Board reviewed detailed information regarding revenues received by DIMA under the Agreement. The Board considered the estimated costs and pre-tax profits realized by DIMA from advising the DWS Funds, as well as estimates of the pre-tax profits attributable to managing the Fund in particular. The Board also received information regarding the estimated enterprise-wide profitability            of the DWS Investments organization with respect to all fund services in totality and by fund. The Board reviewed DIMA's methodology in allocating its costs to the management of the Fund. Based on the information provided, the Board concluded that the pre-tax profits realized by DIMA in connection with the management of the Fund were not unreasonable. 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 (and in some cases is not necessarily prepared on a comparable basis), DIMA and its affiliates' overall profitability with respect to the DWS Investments fund complex (after taking into account distribution and other services provided to the funds by DIMA and its affiliates) was lower than the overall profitability levels of many comparable firms for which such data was available.

**Economies of Scale.** The Board considered whether there are economies of scale with respect to the management of the Fund and whether the Fund benefits from any economies of scale. The Board noted that the Fund's management fee schedule includes fee breakpoints. The Board concluded that the Fund's fee schedule represents an appropriate sharing between the Fund and DIMA of such            economies of scale as may exist in the management of the Fund at current asset levels.

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

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

Based on all of the information considered and the conclusions reached, the Board (including a majority of the Independent Trustees) determined that the continuation of the Agreement is in the best interests of the Fund. In making this determination the Board did not give particular weight to any single factor identified above. The Board considered these factors over the course of numerous meetings, certain of            which were in executive session with only the Independent Trustees and 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 Agreement.

**Summary of Management Fee Evaluation by Independent Fee Consultant**

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.

**Trustees and Officers**

The following table presents certain information regarding the Board Members and Officers of the Trust as of September 30, 2008. Each Board Member's year of birth is set forth in parentheses after his or her name. Unless otherwise noted, (i) each Board Member has engaged in the principal occupation(s) noted in the table for at least the most recent five years, although not necessarily in the same capacity; and (ii) the address            of each Independent Board Member is c/o Dawn-Marie Driscoll, PO Box 100176, Cape Coral, FL 33904. Except as otherwise noted below, the term of office for each Board Member is until the election and qualification of a successor, or until such Board Member sooner dies, resigns, is removed or as otherwise provided in the governing documents of the fund. Because the fund does not hold an annual meeting of shareholders, each Board Member will hold office for an indeterminate period.            The Board Members may also serve in similar capacities with other funds in the fund complex. The Length of Time Served represents the year in which the Board Member joined the board of one or more DWS funds now overseen by the Board.

|        | The 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. |

PwC advised the Fund's Audit Committee that PwC has identified two matters that it determined to be inconsistent with the SEC's auditor independence rules. In the first instance, an employee of PwC had power of attorney over an account which included DWS funds. The employee did not perform any audit services for the DWS Funds, but did work on a non audit project for Deutsche Bank AG. In the second            instance, an employee of PwC served as a nominee shareholder (effectively equivalent to a Trustee) of various companies/trusts since 2001. Some of these companies held shares of Aberdeen, a sub advisor to certain DWS Funds, and of certain funds sponsored by subsidiaries of Deutsche Bank AG.

----

The trustee relationship has ceased. PwC informed the Audit Committee that these matters could have constituted an investment in an affiliate of an audit client in violation of the Rule 2-01(c)(1) of Regulation S-X. PwC advised the Audit Committee that PwC believes its independence had not been impacted as it related to the audits of the Fund. In reaching this conclusion, PwC noted that during the time            of its audit, the engagement team was not aware of the investment and that PwC does not believe these situations affected PwC's ability to act objectively and impartially and to issue a report on financial statements as the funds' independent auditor.
