1 SUPPLEMENT TO THE CURRENTLY EFFECTIVE PROSPECTUSES, SUMMARY PROSPECTUSES AND STATEMENTS OF ADDITIONAL INFORMATION OF EACH OF THE LISTED FUNDS Cash Account Trust Tax-Exempt Portfolio Daily Assets Fund Deutsche Money Market Prime Series Deutsche Variable NAV Money Fund In July of 2014, the Securities and Exchange Commission ( SEC ) adopted money market fund reforms that impact the operation of registered money market funds, including the funds. The funds are required to comply with money market fund reforms by the specified compliance dates, with the latest being October 14, 2016 (the Compliance Date). Under the money market fund reforms, registered money market funds that qualify as retail money market funds and government money market funds will be permitted to continue to utilize the amortized cost method of valuation to seek to transact at a stable net asset value per share ( NAV ) on or after the Compliance Date. A retail money market fund is defined under the money market fund reforms as a fund that has policies and procedures reasonably designed to limit all beneficial owners of the fund to natural persons. Registered money market funds that do not qualify as retail money market funds or government money market funds (collectively, institutional money market funds ) would be required to price and transact in their shares at a floating NAV reflecting current market values for their portfolio securities on or before the Compliance Date. The Deutsche Variable NAV Money Fund currently processes and transacts in its shares at a floating NAV calculated at 4 p.m. each day that the fund is open for business. Retail money market funds and institutional money market funds must also implement policies and procedures reasonably designed to ensure the funds will be able to impose liquidity fees on redemptions and/or redemption gates suspending redemptions under certain limited circumstances and subject to the actions of the fund s Board by the Compliance Date. On or prior to the Compliance Date, each fund and all its share classes will qualify as either a retail money market fund or institutional money market fund as follows: June 15, 2016 PRO_SAISTKR-266 Fund Type Stable NAV Permitted Implementation of Liquidity Fees and/or Redemption Gates Deutsche Money Market Prime Series Retail Money Market Fund Yes Yes Cash Account Trust: Tax-Exempt Portfolio Retail Money Market Fund Yes Yes Daily Assets Fund Institutional Money Market Fund No Yes Deutsche Variable NAV Money Fund Institutional Money Market Fund No Yes Deutsche Retail Money Market Funds On or about September 16, 2016, Deutsche Money Market Prime Series and Tax-Exempt Portfolio of Cash Account Trust (the Deutsche Retail MMFs ) will implement policies and procedures that are reasonably designed to limit beneficial ownership of each fund s shares to natural persons. On such date, only accounts beneficially owned by natural persons will be permitted to retain their shares in each Deutsche Retail MMF. Each Deutsche Retail MMF will continue to operate with its existing investment objective and investment strategies and will continue to seek to maintain a $1.00 stable NAV. (Although each fund will seek to maintain a $1.00 NAV,

2 there is no guarantee that it will be able to do so and if the NAV falls below $1.00, you would lose money.) In addition, each Deutsche Retail MMF will be required to be able to implement liquidity fees and/or redemption gates by the Compliance Date. Natural persons may invest, or continue to invest, in a Deutsche Retail MMF directly or through certain taxadvantaged savings accounts, trusts and other retirement accounts, which may include participant directed defined contribution plans, individual retirement accounts, simplified employee pension arrangements, simple retirement accounts, custodial accounts, deferred compensation plans, medical savings accounts, college savings plans, health savings account plans, or certain other accounts where the ultimate decision maker is an institution (e.g., an investment adviser managing discretionary investment accounts for natural persons or a plan sponsor of a retirement account). In order to separate eligible investors within the funds, the Board of each Deutsche Retail MMF, on the recommendation of Deutsche Investment Management Americas Inc. ( DIMA ), approved the closing of each Deutsche Retail MMF to new investors that are not natural persons effective on or about July 1, On or about September 15, 2016, financial intermediaries will be required to take steps to remove any shareholders on behalf of whom they hold shares in a Deutsche Retail MMF that are not eligible to be invested in the fund. Financial intermediaries will also be required to provide the funds a written statement or other representation that they have in place, and operate in compliance with, policies and procedures that are reasonably designed to limit beneficial ownership of the funds to natural persons. Financial intermediaries will not be permitted to submit purchase orders if they have not provided such a written statement or representation. In order to ensure that the Deutsche Retail MMFs are beneficially owned by natural persons, each fund may redeem investors that do not satisfy the eligibility requirements of the Deutsche Retail MMFs. Each Deutsche Retail MMF will provide advanced written notice of its intent to make any such involuntary redemptions. Effective on or about September 15, 2016, the Deutsche Retail MMFs may involuntarily redeem shares in accounts if Deutsche Retail MMF does not believe that the account is beneficially owned by a natural person. In addition, the share class of Tax Exempt Portfolio noted below will change its name effective on or about July 1, 2016 as follows: Current Share Class Name Deutsche Tax-Exempt Cash Institutional Shares New Share Class Name (Effective on or About July 1, 2016) Deutsche Tax-Exempt Cash Premier Shares June 15, 2016 PRO_SAISTKR-266 2

3 A summary of the key dates and events for the Deutsche Retail MMFs is set forth below: Effective on or about July 1, 2016: o o The Deutsche Retail MMFs will not open any new account of which the beneficial owner is not a natural person. The Deutsche Tax-Exempt Cash Institutional Shares class of Tax-Exempt Portfolio will change its name to Deutsche Tax-Exempt Cash Premier Shares. Effective on or about September 15, 2016: o o o o The Deutsche Retail MMFs may involuntarily redeem shares in accounts if the Deutsche Retail MMF does not believe that the account is beneficially owned by a natural person. Financial intermediaries will be required to take steps to remove any shareholders on behalf of whom they hold shares in a Deutsche Retail MMF that are not eligible to be invested in the fund. Financial intermediaries will be required to have provided the Deutsche Retail MMFs with a written statement or other representation that they have in place, and operate in compliance with, policies and procedures that are reasonably designed to limit beneficial ownership of the funds to natural persons. Financial intermediaries will not be permitted to submit purchase orders if they have not provided such a written statement or representation. Effective on or about September 16, 2016: o The Deutsche Retail MMFs will implement policies and procedures that are reasonably designed to limit beneficial ownership of each fund s shares to natural persons. Effective on or about October 14, 2016: o The Deutsche Retail MMFs will implement policies and procedures reasonably designed to ensure the funds will be able to impose liquidity fees on redemptions and/or redemption gates suspending redemptions under certain limited circumstances and subject to the actions of the fund s Board. Deutsche Institutional Money Market Funds Under the money market fund reforms, all investors, including natural persons, that meet the eligibility requirements may purchase shares of Daily Assets Fund and Deutsche Variable NAV Money Fund (the Deutsche Institutional MMFs ), but the funds will be required to price and transact in their shares at a floating NAV to four decimal places in the case of a fund with a $1.00 target share price (e.g., $1.0000) or an equivalent or more precise level of accuracy for funds with a different share price (e.g., a fund that has a target share price of $10.00 could price its share at $10.000) reflecting current market values for their portfolio securities on or before the Compliance Date. Currently, the Deutsche Variable NAV Money Fund transacts in its shares at a floating NAV calculated at 4 p.m. each business day. DIMA currently expects that the Daily Assets Fund will transition to a floating NAV on or about October 10, As a result, Daily Assets Fund will begin to value its portfolio securities using market based factors and will no longer use the amortized cost method of valuation effective on or about October 10, June 15, 2016 PRO_SAISTKR-266 3

4 In order to provide shareholders with liquidity multiple times per day, DIMA recommended, and the Board of each fund approved, that the NAV for each class of the Deutsche Institutional MMFs be calculated, effective on or about October 10, 2016, as of the following times each day that the fund is open for business: Fund Current NAV Calculation Time New NAV Calculation Times (Effective on or about October 10, 2016) Deutsche Variable NAV Money Fund 4:00 p.m. 9:00 a.m.; 12:00 p.m.; 3:00 p.m.; and 5:00 p.m. Daily Assets Fund 5:00 p.m. 9:00 a.m.; 12:00 p.m.; 3:00 p.m.; and 5:00 p.m. Until such date, the Daily Assets Fund will continue to seek to maintain a stable $1.00 NAV using the amortized cost method to value its portfolio securities. (Although the fund will seek to maintain a $1.00 NAV, there is no guarantee that it will be able to do so and if the NAV falls below $1.00, you would lose money.) Additionally, Deutsche Variable NAV Money Fund will continue to process and transact in its shares at a floating NAV calculated once each business day reflecting current market values for its portfolio securities. Processing of Trade Orders All purchase, redemption and exchange orders must be received in good order and will generally be priced at the NAV next calculated after it is received in good order. If a wire transfer purchase order is received in good order for before 9:00 a.m., 12:00 p.m. or 3:00 p.m. Eastern time, it will normally receive the dividend for that day. Purchase orders processed at 5:00 p.m. Eastern time will not receive the dividend for that day. Redemption orders processed at 9:00 a.m., 12:00 p.m. or 3:00 p.m. will not be entitled to that day s dividend. However, redemption orders processed at 5:00 p.m. will be entitled to the same day dividend. A summary of the key dates and events for the Deutsche Institutional MMFs is set forth below: Effective on or about October 10, 2016: o o o Daily Assets Fund will transition it share price from a stable NAV of $1.00 to a floating NAV. Daily Assets Fund will begin to use market based factors and will no longer use the amortized cost method of valuation to value its portfolio securities. Each Deutsche Institutional MMF will calculate its NAV multiple times each day that the fund is open for business (typically, 9:00 a.m., 12:00 p.m., 3:00 p.m., and 5:00 p.m.). Effective on or about October 14, 2016: o The Deutsche Institutional MMFs will implement policies and procedures reasonably designed to ensure the funds will be able to impose liquidity fees on redemptions and/or redemption gates suspending redemptions under certain limited circumstances and subject to the actions of the fund s Board. June 15, 2016 PRO_SAISTKR-266 4

5 Liquidity Fees and Redemption Gates Effective on or about October 14, 2016, if a Deutsche Retail MMF s or Deutsche Institutional MMF s weekly liquid assets fall below 30%, the Board of the fund may, in its discretion, impose a liquidity fee of up to 2% of the value of the shares redeemed and/or put on a gate to temporarily suspend redemptions. In addition, if a Deutsche Retail MMF s or Deutsche Institutional MMF s weekly liquid assets fall below 10%, the fund must impose a liquidity fee of 1% of the value of the shares redeemed, unless the Board of the fund determines that not doing so is in the best interest of the Fund. Weekly liquid assets include (i) cash, (ii) direct obligations of the U.S. Government, (iii) Government securities that are issued by a person controlled or supervised by and acting as an instrumentality of the U.S. Government pursuant to authority granted by Congress that are issued at a discount to the principal amount to be repaid at maturity without provision for the payment of interest and have a remaining maturity date of 60 days or less, (iv) securities that will mature or are subject to a demand feature that is exercisable and payable within five business days, or (v) amounts receivable and due unconditionally within five business days on pending sales of portfolio securities. A liquidity fee or redemption gate must automatically terminate at the beginning of the next business day once a fund s weekly liquid assets reach at least 30% of its total assets. Additionally, redemption gates may only be put in place for up to 10 business days in any 90-day period. In addition, the Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of the fund. To the extent a fund implements a liquidity fee, it is currently expected that the liquidity fee would generally apply to all redemptions at the first net asset value calculation on the next business day following notification to financial intermediaries and shareholders. However, the Board, in its discretion, may elect to impose a liquidity fee on an intra-day basis. A liquidity fee will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. A liquidity fee would reduce the amount you receive upon redemption of your shares. In the event that a fund imposes a redemption gate, the fund or any financial intermediary will not accept a redemption request until the fund provides notice that the redemption gate has been removed. It is also currently expected that a redemption gate would be implemented concurrently with the notification to financial intermediaries and shareholders. Redemption requests that are received when a redemption gate is imposed will be cancelled without further notice. If you wish to redeem once the redemption gate has been lifted, you will need to submit a new redemption request. When a liquidity fee or redemption gate is in place, a fund may elect to continue to permit the purchase of fund shares. The imposition and termination of liquidity fees or redemption gates is required to be reported to the SEC on Form N-CR. In addition, a fund will communicate the decision to impose a liquidity fee or redemption gate to shareholders via the Deutsche Funds websites (dbadvisorsliquidity.com/us or deutschefunds.com) and through a supplement to the affected funds prospectuses.

Such revenue sharing payments are in addition to any distribution or service fees payable under any Rule 12b-1 or service plan of the fund, any record keeping/sub-transfer agency/networking fees payable by the fund (generally through the Distributor or an affiliate) and/or the Distributor or Advisor to certain financial advisors for performing such services and any sales charge, commissions, non-cash compensation arrangements expressly permitted under applicable rules of the Financial Industry Regulatory Authority or other concessions described October 21, 2015 PROSTKR-551

7 in the fee table or elsewhere in this prospectus or the Statement of Additional Information as payable to all financial advisors. For example, the Advisor, the Distributor and/or their affiliates may compensate financial advisors for providing the fund with shelf space or access to a third party platform or fund offering list or other marketing programs, including, without limitation, inclusion of the fund on preferred or recommended sales lists, mutual fund supermarket platforms and other formal sales programs; granting the Distributor access to the financial advisor s sales force; granting the Distributor access to the financial advisor s conferences and meetings; assistance in training and educating the financial advisor s personnel; and obtaining other forms of marketing support. The level of revenue sharing payments made to financial advisors may be a fixed fee or based upon one or more of the following factors: gross sales, current assets and/or number of accounts of the fund attributable to the financial advisor, the particular fund or fund type or other measures as agreed to by the Advisor, the Distributor and/or their affiliates and the financial advisors or any combination thereof. The amount of these revenue sharing payments is determined at the discretion of the Advisor, the Distributor and/or their affiliates from time to time, may be substantial, and may be different for different financial advisors based on, for example, the nature of the services provided by the financial advisor. The Advisor, the Distributor and/or their affiliates currently make revenue sharing payments from their own assets in connection with the sale and/or distribution of Deutsche fund shares or the retention and/or servicing of investors and Deutsche fund shares to financial advisors in amounts that generally range from 0.01% up to 0.52% of assets of the fund serviced and maintained by the financial advisor, 0.05% to 0.25% of sales of the fund attributable to the financial advisor, a flat fee of up to $120,000, or any combination thereof. These amounts are subject to change at the discretion of the Advisor, the Distributor and/or their affiliates. Receipt of, or the prospect of receiving, this additional compensation may influence your financial advisor s recommendation of the fund or of any particular share class of the fund. You should review your financial advisor s compensation disclosure and/or talk to your financial advisor to obtain more information on how this compensation may have influenced your financial advisor s recommendation of the fund. Additional information regarding these revenue sharing payments is included in the fund s Statement of Additional Information, which is available to you on request at no charge (see the back cover of this prospectus for more information on how to request a copy of the Statement of Additional Information). The following paragraph is for all funds except Deutsche Variable NAV Money Fund: The Advisor, the Distributor and/or their affiliates may also make such revenue sharing payments to financial advisors under the terms discussed above in connection with the distribution of both Deutsche funds and non-deutsche funds by financial advisors to retirement plans that obtain record keeping services from ADP, Inc. or to 403(b) plans that obtain record keeping services from ExpertPlan Inc., a subsidiary of Ascensus, Inc., on the DeAWM-branded retirement plan platform (the Platform ). The level of revenue sharing payments are based upon sales of both the Deutsche funds and the non-deutsche funds by the financial advisor on the Platform or current assets of both the Deutsche funds and the non-deutsche funds serviced and maintained by the financial advisor on the Platform. It is likely that broker-dealers that execute portfolio transactions for the fund will include firms that also sell shares of the Deutsche funds to their customers. However, the Advisor will not consider sales of Deutsche fund shares as a factor in the selection of broker-dealers to execute portfolio transactions for the Deutsche funds. Accordingly, the Advisor has implemented policies and procedures reasonably designed to prevent its traders from considering sales of Deutsche fund shares as a factor in the selection of broker-dealers to execute portfolio transactions for the fund. In addition, the Advisor, the Distributor and/or their affiliates will not use fund brokerage to pay for their obligation to provide additional compensation to financial advisors as described above.

10 Tax-Exempt Portfolio INVESTMENT OBJECTIVE The fund seeks to provide maximum current income that is exempt from federal income taxes to the extent consistent with stability of capital. FEES AND EXPENSES OF THE FUND These are the fees and expenses you may pay when you buy and hold shares. SHAREHOLDER FEES (paid directly from your investment) None ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a%ofthevalueofyourinvestment) Management fee 0.07 Distribution/service (12b-1) fees None Other expenses 0.15 Total annual fund operating expenses 0.22 Fee waiver/expense reimbursement 0.02 Total annual fund operating expenses after fee waiver/ expense reimbursement 0.20 The Advisor has contractually agreed through September 30, 2016 to waive its fees and/or reimburse certain operating expenses of the Deutsche Tax-Exempt Cash Institutional Shares of the Tax-Exempt Portfolio to the extent necessary to maintain the total annual operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest expenses) at 0.20%. The agreement may only be terminated with the consent of the fund s Board. EXAMPLE This Example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund s operating expenses (including one year of capped expenses in each period) remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 1 Year 3 Years 5 Years 10 Years $20 $69 $122 $278 PRINCIPAL INVESTMENT STRATEGY The fund normally invests at least 80% of its net assets in municipal securities, the income from which is free from regular federal income tax and alternative minimum tax (AMT). This policy is fundamental and may not be changed without shareholder approval. The fund is a money market fund that is managed in accordance with federal regulations, which govern the quality, maturity, diversity and liquidity of instruments in which a money market fund may invest. The fund may invest in municipal trust securities (MTRs), general obligation and revenue notes and bonds, municipal obligations backed by third parties, obligations of the territories or Commonwealths of the US and other municipal instruments paying a fixed, variable or floating interest rate. The fund is designed for investors in a moderate to high tax bracket who are interested in federal tax-exempt income along with the liquidity and stability that a money market fund is designed to offer. Working in consultation with portfolio management, a credit team screens potential securities and develops a list of those that the fund may buy. Portfolio management, looking for attractive yield and weighing considerations such as credit quality, economic outlooks and possible interest rate movements, then decides which securities on this list to buy. Prospectus August 1, Tax-Exempt Portfolio

11 MAIN RISKS There are several risk factors that could reduce the yield you get from the fund, cause the fund s performance to trail that of other investments, or cause you to lose money. Money market fund risk. An investment in the fund is not insured or guaranteed by the FDIC or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, this share price isn t guaranteed, and if it falls below $1.00 you would lose money. The Advisor is not obligated to take any action to maintain the $1.00 share price. The share price could fall below $1.00 as a result of the actions of one or more large investors in the fund. The credit quality of the fund s holdings can change rapidly in certain markets, and the default of a single holding could cause the fund s share price to fall below $1.00, as could periods of high redemption pressures and/or illiquid markets. Interest rate risk. Rising interest rates could cause the value of the fund s investments and therefore its share price as well to decline. Conversely, any decline in interest rates is likely to cause the fund s yield to decline, and during periods of unusually low interest rates, the fund s yield may approach zero. A low interest rate environment may prevent the fund from providing a positive yield or paying fund expenses out of current income and, at times, could impair the fund s ability to maintain a stable $1.00 share price. Over time, the total return of a money market fund may not keep pace with inflation, which could result in a net loss of purchasing power for long-term investors. Credit risk. The fund s performance could be hurt and the fund s share price could fall below $1.00 if an issuer of a debt security suffers an adverse change in financial condition that results in the issuer not making timely payments of interest or principal, a security downgrade or an inability to meet a financial obligation. Liquidity and transaction risk. The liquidity of portfolio securities can deteriorate rapidly due to credit events affecting issuers or guarantors or due to general market conditions and a lack of willing buyers. When there are no willing buyers and an instrument cannot be readily sold at a desired time or price, the fund may have to accept a lower price or may not be able to sell the instrument at all. An inability to sell one or more portfolio securities can adversely affect the fund s ability to maintain a $1.00 share price or prevent the fund from being able to take advantage of other investment opportunities. Unusual market conditions, an unusually high volume of redemption requests or other similar conditions could cause the fund to be unable to pay redemption proceeds within a short period of time. If the fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the fund s ability to maintain a $1.00 share price. Municipal securities risk. The fund could be impacted by events in the municipal securities market, including the supply and demand for municipal securities. Negative events, such as severe fiscal difficulties, bankruptcy of one or more issuers, an economic downturn, unfavorable legislation, court rulings or political developments, or reduced monetary support from the federal government could hurt fund performance. Security selection risk. Although short-term securities are relatively stable investments, it is possible that the securities in which the fund invests will not perform as expected. This could cause the fund s returns to lag behind those of similar money market funds and could result in a decline in share price. Municipal trust receipts risk. The fund s investment in MTRs is subject to similar risks as other investments in debt obligations, including interest rate risk, credit risk and security selection risk. Additionally, investments in MTRs raise certain tax issues that may not be presented by direct investments in municipal securities. There is some risk that certain issues could be resolved in a manner that could adversely impact the performance of the fund. Tax risk. Any distributions to shareholders that represent income from taxable securities will generally be taxable as ordinary income at both the state and federal levels, while other distributions, such as capital gains, are taxable to the same extent they would be for any mutual fund. New federal or state governmental action could adversely affect the tax-exempt status of securities held by the fund, resulting in a higher tax liability for shareholders and potentially hurting fund performance as well. Counterparty risk. A financial institution or other counterparty with whom the fund does business, or that underwrites, distributes or guarantees any investments or contracts that the fund owns or is otherwise exposed to, may decline in financial health and become unable to honor its commitments. This could cause losses for the fund or could delay the return or delivery of collateral or other assets to the fund. US territory and Commonwealth obligations risk. Adverse political and economic conditions and developments affecting any territory or Commonwealth of the US may, in turn, negatively affect the value of the fund s holdings in such obligations. In recent years, Puerto Rico has experienced a recession and difficult economic conditions, which may negatively affect the value of the fund s holdings in Puerto Rico municipal obligations. Prepayment and extension risk. When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the fund s assets tied up in lower interest debt obligations. Ultimately, any unexpected Prospectus August 1, Tax-Exempt Portfolio

12 behavior in interest rates could increase the volatility of the fund s yield and could hurt fund performance. Prepayments could also create capital gains tax liability in some instances. Regulatory risk. In July 2014, the SEC adopted money market fund reform intended to address potential systemic risks associated with money market funds and to improve transparency for money market fund investors. The fund is required to comply with money market reforms by the specified compliance dates, with the latest being October 14, As a result, the fund may be required to take certain steps that will impact its structure and/or operations, which could impact the return potential of the fund. PAST PERFORMANCE How a fund s returns vary from year to year can give an idea of its risk. Past performance may not indicate future results. All performance figures below assume that dividends were reinvested. The 7-day yield, which is often referred to as the current yield, is the income generated by the fund over a seven-day period. This amount is then annualized, which means that we assume the fund generates the same income every week for a year. For more recent performance figures and the current yield, go to deutscheliquidity.com (the Web site does not form a part of this prospectus) or call the telephone number included in this prospectus. CALENDAR YEAR TOTAL RETURNS (%) (Deutsche Tax-Exempt Cash Institutional Shares) Returns Period ending Best Quarter 0.90% September 30, 2007 Worst Quarter 0.00% March 31, 2014 Year-to-Date 0.00% June 30, 2015 AVERAGE ANNUAL TOTAL RETURNS (For periods ended 12/31/2014 expressed as a %) Class Inception 1 Year 5 Years 10 Years 11/17/ Total returns would have been lower if operating expenses had not been reduced.

The fund normally invests at least 80% of its net assets in municipal securities, the income from which is free from regular federal income tax and alternative minimum tax (AMT). This policy is fundamental and may not be changed without shareholder approval. The fund may invest in municipal securities of various locales, including any territory or Commonwealth of the US. The fund is a money market fund that is managed in accordance with federal regulations, which govern the quality, maturity, diversity and liquidity of instruments in which a money market fund may invest. The fund follows policies designed to seek to maintain a stable $1.00 share price: Fund securities are denominated in US dollars and, at the time of purchase, have remaining maturities of 397 days (about 13 months) or less, or have certain maturity shortening features (such as interest rate resets and demand features) that have the effect of reducing their maturities to 397 days or less. The fund maintains a dollar-weighted average maturity of (i) 60 days or less and (ii) 120 days or less determined without regard to interest rate resets. The fund maintains certain minimum liquidity standards such that: - the fund may not purchase a security other than a security offering weekly liquidity if, immediately after purchase, the fund would have invested less than 30% of its total assets in securities offering weekly liquidity (includes securities that mature or are subject to demand within five business days, cash, direct US government obligations and government agency discount notes with remaining maturities of 60 days or less); and - the fund may not purchase an illiquid security if, immediately after purchase, the fund would have invested more than 5% of its total assets in illiquid securities (securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the market value ascribed to them by the fund). The fund pursues its objective by investing in high quality, short-term municipal obligations. The fund is designed for investors in a moderate to high tax bracket who are interested in federal tax-exempt income along with the liquidity and stability that a money market fund is designed to offer. The fund primarily invests in the following types of investments: Municipal trust receipts (MTRs), also called municipal asset-backed securities, floating rate trust certificates, or municipal securities trust receipts. MTRs are trusts that hold municipal securities and that offer purchasers (such as the fund) a conditional right to sell their interest in the underlying securities to a financial institution at par value plus accrued interest. The fund may invest up to 50% of its net assets in MTRs, as well as an additional 10% of net assets on a temporary basis to manage inflows into the fund. General obligation notes and bonds, which an issuer backs with its full faith and credit (taxing power). Revenue notes and bonds, which are payable from specific revenue sources. These are often tied to the public works projects the bonds are financing, but are not generally backed by the issuer s taxing power. Tax-exempt commercial paper, which is tax-exempt debt of borrowers that typically matures in 270 days or less. Short-term municipal notes, such as tax anticipation notes, that are issued in anticipation of the receipt of tax revenues. Municipal obligations backed by letters of credit (a document issued by a bank guaranteeing the issuer s payments for a stated amount), general bank guarantees or municipal bond insurance.

14 Floating rate bonds, whose interest rates vary with changes in specified market rates or indices. The fund may invest in high quality floating rate bonds with maturities of one year or more if it has the right to sell them back at their face value within 397 days of purchase. Tax-exempt private activity bonds, which are revenue bonds that finance non-governmental activities, such as private industry construction and which meet certain tax law requirements. Securities of other investment companies, including variable rate demand preferred securities of closed-end investment companies that are eligible for purchase by money market funds (generally, because such preferred securities are structured as unconditional demand instruments with a third party demand provider, i.e., guarantor). Obligations of the territories and Commonwealths of the US, such as Puerto Rico, the US Virgin Islands, Guam and their agencies and authorities. Management process. The fund buys short-term municipal obligations that the Advisor determines present minimal credit risks and that at the time of purchase: have received one of the two highest short-term ratings from two nationally recognized statistical rating organizations (NRSROs) or one NRSRO if that NRSRO is the only NRSRO that rates such obligations; or have no short-term rating, but are deemed by the Advisor to be of comparable quality to a security that has received a rating in one of the two highest shortterm categories; provided that, if the security has a longterm rating, it must be rated in one of the top three highest long-term rating categories by two NRSROs or one NRSRO if that NRSRO is the only NRSRO that rates such obligation; and do not result in the fund holding more than 3% of its total assets in second tier securities (which are otherwise eligible securities that do not have the requisite ratings in the highest short-term rating category or, if unrated, are not deemed by the Advisor to be comparable to that category), provided the fund will not purchase a second tier security with a remaining maturity greater than 45 days. Working in consultation with portfolio management, a credit team screens potential securities and develops a list of those that the fund may buy. Portfolio management, looking for attractive yield and weighing considerations such as credit quality, economic outlooks and possible interest rate movements, then decides which securities on this list to buy. Portfolio management may adjust the fund s exposure to interest rate risk, typically seeking to take advantage of possible rises in interest rates and to preserve yield when interest rates appear likely to fall. MAIN RISKS There are several risk factors that could reduce the yield you get from the fund, cause the fund s performance to trail that of other investments, or cause you to lose money. Money market fund risk. An investment in the fund is not insured or guaranteed by the FDIC or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, this share price isn t guaranteed, and if it falls below $1.00 you would lose money. The Advisor is not obligated to take any action to maintain the $1.00 share price. The share price could fall below $1.00 as a result of the actions of one or more large investors in the fund. The credit quality of the fund s holdings can change rapidly in certain markets, and the default of a single holding could cause the fund s share price to fall below $1.00, as could periods of high redemption pressures and/or illiquid markets. Interest rate risk. Rising interest rates could cause the value of the fund s investments and therefore its share price as well to decline. Conversely, any decline in interest rates is likely to cause the fund s yield to decline, and during periods of unusually low interest rates, the fund s yield may approach zero. A low interest rate environment may prevent the fund from providing a positive yield or paying fund expenses out of current income and, at times, could impair the fund s ability to maintain a stable $1.00 share price. Over time, the total return of a money market fund may not keep pace with inflation, which could result in a net loss of purchasing power for long-term investors. Credit risk. The fund s performance could be hurt and the fund s share price could fall below $1.00 if an issuer of a debt security suffers an adverse change in financial condition that results in the issuer not making timely payments of interest or principal, a security downgrade or an inability to meet a financial obligation. For securities that rely on third-party guarantors to support their credit quality, the same risks may apply if the financial condition of the guarantor deteriorates or the guarantor ceases to insure securities. Because guarantors may insure many types of securities, including subprime mortgage bonds and other high-risk bonds, their financial condition could deteriorate as a result of events that have little or no connection to securities owned by the fund. Liquidity and transaction risk. The liquidity of portfolio securities can deteriorate rapidly due to credit events affecting issuers or guarantors or due to general market conditions and a lack of willing buyers. When there are no willing buyers and an instrument cannot be readily sold at a desired time or price, the fund may have to accept a lower price or may not be able to sell the instrument at all. An inability to sell one or more portfolio securities can adversely affect the fund s ability to maintain a $1.00 share price or prevent the fund from being able to take advantage of other investment opportunities.

15 Unusual market conditions, an unusually high volume of redemption requests or other similar conditions could cause the fund to be unable to pay redemption proceeds within a short period of time. If the fund is forced to sell securities at an unfavorable time and/or under unfavorable conditions, such sales may adversely affect the fund s ability to maintain a $1.00 share price. Certain shareholders, including clients or affiliates of the Advisor, may from time to time own or control a significant percentage of the fund s shares. These shareholders may include, for example, institutional investors and other shareholders whose buy-sell decisions are controlled by a single decision maker. Redemptions by these shareholders, or a high volume of redemption requests generally, may further increase the fund s liquidity risk and may impact the fund s ability to maintain a $1.00 share price. Municipal securities risk. The fund could be impacted by events in the municipal securities market, including the supply and demand for municipal securities. Negative events, such as severe fiscal difficulties, bankruptcy of one or more issuers, an economic downturn, unfavorable legislation, court rulings or political developments, or reduced monetary support from the federal government could hurt fund performance. Security selection risk. Although short-term securities are relatively stable investments, it is possible that the securities in which the fund invests will not perform as expected. This could cause the fund s returns to lag behind those of similar money market funds and could result in a decline in share price. Municipal trust receipts risk. The fund s investment in MTRs is subject to similar risks as other investments in debt obligations, including interest rate risk, credit risk and security selection risk. Additionally, investments in MTRs raise certain tax issues that may not be presented by direct investments in municipal securities. There is some risk that certain issues could be resolved in a manner that could adversely impact the performance of the fund. Tax risk. Any distributions to shareholders that represent income from taxable securities will generally be taxable as ordinary income at both the state and federal levels, while other distributions, such as capital gains, are taxable to the same extent they would be for any mutual fund. New federal or state governmental action could adversely affect the tax-exempt status of securities held by the fund, resulting in a higher tax liability for shareholders and potentially hurting fund performance as well. Counterparty risk. A financial institution or other counterparty with whom the fund does business, or that underwrites, distributes or guarantees any investments or contracts that the fund owns or is otherwise exposed to, may decline in financial health and become unable to honor its commitments. This could cause losses for the fund or could delay the return or delivery of collateral or other assets to the fund. US territory and Commonwealth obligations risk. Adverse political and economic conditions and developments affecting any territory or Commonwealth of the US may, in turn, negatively affect the value of the fund s holdings in such obligations. In recent years, Puerto Rico has experienced a recession and difficult economic conditions, which may negatively affect the value of the fund s holdings in Puerto Rico municipal obligations. Prepayment and extension risk. When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the fund s assets tied up in lower interest debt obligations. Ultimately, any unexpected behavior in interest rates could increase the volatility of the fund s yield and could hurt fund performance. Prepayments could also create capital gains tax liability in some instances. Regulatory risk. In July 2014, the SEC adopted money market fund reform intended to address potential systemic risks associated with money market funds and to improve transparency for money market fund investors. The fund is required to comply with money market reforms by the specified compliance dates, with the latest being October 14, As a result, the fund may be required to take certain steps that will impact its structure and/or operations, which could impact the return potential of the fund. OTHER POLICIES While the previous pages describe the main points of the fund s strategy and risks, there are a few other matters to know about: Although major changes tend to be infrequent, the fund s Board could change the fund s investment objective without shareholder approval. For temporary defensive purposes, or when acceptable short-term municipal securities are not available, more than 20% of the fund s net assets may be held in cash or invested in short-term taxable instruments, including obligations of the US government, its agencies or instrumentalities, other short-term high quality rated debt securities or, if unrated, determined to be of comparable quality in the opinion of the Advisor, commercial paper, bank obligations, including negotiable certificates of deposit, time deposits and bankers acceptances, and repurchase agreements. Short-term investments may also include shares of money market funds. To the extent the fund invests in such instruments, the fund will not be pursuing its investment objective. However, portfolio management may choose not to use these strategies for various reasons, even in volatile market conditions. Prospectus August 1, Fund Details

FINANCIAL INTERMEDIARY SUPPORT PAYMENTS The Advisor, the Distributor and/or their affiliates may pay additional compensation, out of their own assets and not as an additional charge to the fund, to selected affiliated and unaffiliated brokers, dealers, participating insurance companies or other financial intermediaries ( financial advisors ) in connection with the sale and/or distribution of fund shares or the retention and/or servicing of fund investors and fund shares ( revenue sharing ). Such revenue sharing payments are in addition to any distribution or service fees payable under any Rule 12b-1 or service plan of the fund, any record keeping/sub-transfer agency/networking fees payable by the fund (generally through the Distributor or an affiliate) and/or the Distributor or Advisor to certain financial advisors for performing such services and any sales charge, commissions, non-cash compensation arrangements expressly permitted under applicable rules of the Financial Industry Regulatory Authority or other concessions described in the fee table or elsewhere in this prospectus or the Statement of Additional Information as payable to all financial advisors. For example, the Advisor, the Distributor and/or their affiliates may compensate financial advisors for providing the fund with shelf space or access to a third party platform or fund offering list or other marketing programs, including, without limitation, inclusion of the fund on preferred or recommended sales lists, mutual fund supermarket platforms and other formal sales programs; granting the Distributor access to the financial advisor s sales force; granting the Distributor access to the financial advisor s conferences and meetings; assistance in training and educating the financial advisor s personnel; and obtaining other forms of marketing support. The level of revenue sharing payments made to financial advisors may be a fixed fee or based upon one or more of the following factors: gross sales, current assets and/or number of accounts of the fund attributable to the financial advisor, the particular fund or fund type or other measures as agreed to by the Advisor, the Distributor and/or their affiliates and the financial advisors or any combination thereof. The amount of these revenue sharing payments is determined at the discretion of the Advisor, the Distributor and/or their affiliates from time to time, may be substantial, and may be different for different financial advisors based on, for example, the nature of the services provided by the financial advisor. The Advisor, the Distributor and/or their affiliates currently make revenue sharing payments from their own assets in connection with the sale and/or distribution of Deutsche fund shares or the retention and/or servicing of investors and Deutsche fund shares to financial advisors in amounts that generally range from 0.01% up to 0.57% of assets of the fund serviced and maintained by the financial advisor, 0.05% to 0.25% of sales of the fund attributable to the financial advisor, a flat fee of up to $120,000, or any Prospectus August 1, Investing in the Fund

20 combination thereof. These amounts are subject to change at the discretion of the Advisor, the Distributor and/or their affiliates. Receipt of, or the prospect of receiving, this additional compensation may influence your financial advisor s recommendation of the fund or of any particular share class of the fund. You should review your financial advisor s compensation disclosure and/or talk to your financial advisor to obtain more information on how this compensation may have influenced your financial advisor s recommendation of the fund. Additional information regarding these revenue sharing payments is included in the fund s Statement of Additional Information, which is available to you on request at no charge (see the back cover of this prospectus for more information on how to request a copy of the Statement of Additional Information). The Advisor, the Distributor and/or their affiliates may also make such revenue sharing payments to financial advisors under the terms discussed above in connection with the distribution of both Deutsche funds and non-deutsche funds by financial advisors to retirement plans that obtain record keeping services from ADP, Inc. or to 403(b) plans that obtain record keeping services from ExpertPlan Inc., a subsidiary of Ascensus, Inc., on the DeAWM-branded retirement plan platform (the Platform ). The level of revenue sharing payments are based upon sales of both the Deutsche funds and the non-deutsche funds by the financial advisor on the Platform or current assets of both the Deutsche funds and the non-deutsche funds serviced and maintained by the financial advisor on the Platform. It is likely that broker-dealers that execute portfolio transactions for the fund will include firms that also sell shares of the Deutsche funds to their customers. However, the Advisor will not consider sales of Deutsche fund shares as a factor in the selection of broker-dealers to execute portfolio transactions for the Deutsche funds. Accordingly, the Advisor has implemented policies and procedures reasonably designed to prevent its traders from considering sales of Deutsche fund shares as a factor in the selection of broker-dealers to execute portfolio transactions for the fund. In addition, the Advisor, the Distributor and/or their affiliates will not use fund brokerage to pay for their obligation to provide additional compensation to financial advisors as described above. POLICIES YOU SHOULD KNOW ABOUT Along with the information on the previous pages, the policies below may affect you as a shareholder. Some of this information, such as the section on distributions and taxes, applies to all investors, including those investing through a financial advisor. If you are investing through a financial advisor or through a retirement plan, check the materials you received from them about how to buy and sell shares because particular financial advisors or other intermediaries may adopt policies, procedures or limitations that are separate from those described in this prospectus. Please note that a financial advisor or other intermediary may charge fees separate from those charged by the fund and may be compensated by the fund. Keep in mind that the information in this prospectus applies only to the shares offered herein. Other share classes are described in separate prospectuses and have different fees, requirements and services. POLICIES ABOUT TRANSACTIONS To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. When you open an account, we will ask for your name, address, date of birth and other information that will allow us to identify you. Some or all of this information will be used to verify the identity of all persons opening an account. We might request additional information about you (which may include certain documents, such as articles of incorporation for companies) to help us verify your identity and, in some cases, more information and/or documents may be required to conduct the verification. The information and documents will be used solely to verify your identity. We will attempt to collect any missing required and requested information by contacting you or your financial advisor. If we are unable to obtain this information within the time frames established by the fund, then we may reject your application and order. The fund will not invest your purchase until all required and requested identification information has been provided and your application has been submitted in good order. After we receive all the information, your application is deemed to be in good order and we accept your purchase, you will receive the share price next calculated. If we are unable to verify your identity within time frames established by the fund, after a reasonable effort to do so, you will receive written notification. With certain limited exceptions, only US residents may invest in the fund. Because orders placed through a financial advisor must be forwarded to the transfer agent before they can be processed, you ll need to allow extra time. Your financial advisor should be able to tell you approximately when your order will be processed. It is the responsibility of your financial advisor to forward your order to the transfer agent in a timely manner. Transaction Processing. Orders for the purchase of shares by wire transfer will normally be effective at the share price next computed after receipt of the wire transfer of the amount to be invested. If a wire transfer purchase order is received in good order before 3:00 p.m. Eastern time, it will normally receive the dividend for that day. Prospectus August 1, Investing in the Fund
