Institutional Class Exchange Privilege. The following persons may, subject to certain limitations, exchange Institutional Class shares for Deutsche Money Market Fund shares of Deutsche Money Market Prime Series: (1) a current or former director or trustee of Deutsche mutual funds; and (2) an employee, the employee s spouse or life partner and children or stepchildren age 21 or younger of Deutsche Bank or its affiliates or a subadvisor to any fund in the Deutsche mutual fund family or a broker-dealer authorized to sell shares of the Deutsche mutual funds. PART III The following information replaces the existing disclosure in the Investing in the Funds Financial Intermediary Support Payments section of each fund s/portfolio s Prospectus: FINANCIAL INTERMEDIARY SUPPORT PAYMENTS (NOT APPLICABLE TO CLASS R6) 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 charges, 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. In addition, revenue sharing payments may consist of the Distributor s and/or its affiliates payment or reimbursement of ticket charges that would otherwise be assessed by a financial advisor on an investor s fund transactions. 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 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 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 $143,750, or any combination thereof. These amounts are annual figures typically paid on a quarterly basis and 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). September 26, 2017 PROSTKR-942 2
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 Ascensus, Inc. on the Deutsche AM-branded retirement plan platform (the Platform ). The level of revenue sharing payments is 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.

Deutsche Limited Maturity Quality Income Fund INVESTMENT OBJECTIVE The fund seeks to provide current income consistent with the preservation of capital and liquidity. 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 % of the value of your investment) Management fee 0.15 Distribution/service (12b-1) fees None Other expenses 1.23 Total annual fund operating expenses 1.38 Fee waiver/expense reimbursement 0.78 Total annual fund operating expenses after fee waiver/ expense reimbursement 0.60 The Advisor has contractually agreed through November 30, 2017 to waive its fees and/or reimburse fund expenses to the extent necessary to maintain the fund s total annual operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest expenses) at a ratio no higher than 0.60% for Investment Class. 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 $61 $360 $681 $1,590 PORTFOLIO TURNOVER The fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover may indicate higher transaction costs and may mean higher taxes if you are investing in a taxable account. These costs are not reflected in annual fund operating expenses or in the expense example, and can affect the fund s performance. Portfolio turnover rate for the period from October 5, 2015 (commencement of operations) through August 31, 2016: 161%. PRINCIPAL INVESTMENT STRATEGY Main investments. The fund seeks to achieve its objective by investing mainly in high quality, short-term, US dollar denominated fixed-income instruments, including obligations of US and foreign banks and financial institutions, corporate obligations, US government securities, municipal securities, repurchase agreements and asset-backed securities paying a fixed, variable or floating interest rate. Under normal circumstances, the fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, determined at the time of purchase, in high quality, short-term, US dollar denominated fixed-income instruments. For this purpose, high quality shall include short-term fixed-income instruments that are within the fund s credit quality guidelines below. All instruments will be US dollar denominated, although they may be issued by a foreign bank or corporation, or a US affiliate of a foreign bank or corporation, or a foreign government or its agencies. The fund may have significant exposure to obligations of banks and other financial institutions. Prospectus December 1, 2016 1 Deutsche Limited Maturity Quality Income Fund
The fund may invest no more than 5% of its total assets in any single issuer (other than cash and cash items, US government securities, repurchase agreements collateralized by these same securities, or securities of other investment companies). Credit Quality Guidelines. The short-term securities purchased by the fund (i) will have 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 security; or (ii) may 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 short-term categories; provided that, if the security has a long-term 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. The credit quality guidelines shall be applied at the time of purchase. Maturity Guidelines. The dollar-weighted average effective portfolio maturity of the fund normally will be 90 days or less. A fund s dollar-weighted average effective portfolio maturity is a dollar-weighted average measure of the maturity of a fund s portfolio securities, taking into account maturity-shortening provisions, such as the date of an instrument s next interest rate reset date or demand features. In determining the dollar-weighted average effective portfolio maturity, portfolio management will generally take into account the earlier of the period remaining until the date on which, in accordance with the terms of the fixed-income instrument, the principal amount must unconditionally be paid, or in the case of a fixed-income instrument called for redemption, the date on which the redemption payment must be made, or the interest rate reset date for variable or floating rate obligations. In addition, the fund will buy individual securities with final maturities of 13 months or less, or that have features with the effect of reducing their maturities to 13 months or less at the time of purchase. Management process. Portfolio management will screen potential securities and develop a list of those securities that the fund may purchase based on its investment policies. Portfolio management will weigh such factors as credit quality, economic outlook, market liquidity, and possible interest rate movements in selecting securities to purchase. Portfolio management will buy and hold or sell securities if there is a change in credit quality, economic outlook or market liquidity. Portfolio management may also buy and hold or sell securities to adjust the fund s exposure to interest rate risk, typically seeking to take advantage of a possible rise in interest rates and to preserve yield when interest rates appear likely to fall. Securities Lending. The fund may lend securities (up to one-third of total assets) to approved institutions. THE FUND IS NOT A MONEY MARKET FUND, DOES NOT ATTEMPT TO MAINTAIN A STABLE NET ASSET VALUE, DOES NOT FOLLOW THE PORTFOLIO QUALITY AND RISK DIVERSIFICATION OR OTHER RISK LIMITING PROVISIONS REQUIRED OF MONEY MARKET FUNDS PURSUANT TO RULE 2A-7 AND DOES NOT QUALIFY FOR THE TAX RELIEF AFFORDED TO MONEY MARKET FUNDS BY THE U.S. TREASURY. Unlike a money market fund, the fund is not subject to the risk-limiting conditions of Rule 2a-7 under the Investment Company Act of 1940 with respect to portfolio maturity, quality, diversification and liquidity. For example, the fund may: (1) maintain a dollar-weighted average portfolio maturity of greater than 60 calendar days; (2) invest more than 5% of its total assets in illiquid securities; and (3) invest without any minimum daily or weekly liquidity requirements. Therefore, the fund may be subject to greater credit risk, interest rate risk and liquidity risk than a money market fund (see the Main Risks section). Some of the fund s portfolio securities may not qualify as an eligible investment for a money market fund. MAIN RISKS There are several risk factors that could hurt the fund s performance, cause you to lose money or cause the fund s performance to trail that of other investments. The fund may not achieve its investment objective, and is not intended to be a complete investment program. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. Interest rate risk. When interest rates rise, prices of debt securities generally decline. The fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates. The longer the duration of the fund s debt securities, the more sensitive it will be to interest rate changes. (As a general rule, a 1% rise in interest rates means a 1% fall in value for every year of duration.) A low interest rate environment may prevent the fund from providing a positive yield or paying fund expenses out of current income. Credit risk. The fund s performance could be hurt 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. Prospectus December 1, 2016 2 Deutsche Limited Maturity Quality Income Fund
Some securities issued by US government agencies or instrumentalities are backed by the full faith and credit of the US government. Other securities that are supported only by the credit of the issuing agency or instrumentality are subject to greater credit risk than securities backed by the full faith and credit of the US government. This is because the US government might provide financial support, but has no obligation to do so, if there is a potential or actual loss of principal or failure to make interest payments. Market Risk. Although individual securities may outperform the market, the entire market may decline as a result of rising interest rates, regulatory developments or deteriorating economic conditions. Repurchase agreement risk. If the party that sells the securities to the fund defaults on its obligation to repurchase them at the agreed-upon time and price, the fund could lose money. Liquidity risk. In certain situations, it may be difficult or impossible to sell an investment and/or the fund may sell certain investments at a price or time that is not advantageous in order to meet redemption requests or other cash needs. Unusual market conditions, such as an unusually high volume of redemptions or other similar conditions could increase liquidity risk for the fund. 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 share price and yield and could hurt fund performance. Prepayments could also create capital gains tax liability in some instances. Security selection risk. The securities in the fund s portfolio may decline in value. Portfolio management could be wrong in its analysis of industries, companies, economic trends, the relative attractiveness of different securities or other matters. Focus risk. To the extent that the fund focuses its investments in particular industries, asset classes or sectors of the economy, any market price movements, regulatory or technological changes, or economic conditions affecting companies in those industries, asset classes or sectors may have a significant impact on the fund s performance. The fund may have significant exposure to obligations of banks and other financial institutions and market price movements, regulatory or technological changes, or economic conditions affecting such issuers could significantly impact the fund s performance. 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. 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. Foreign investment risk. The fund faces the risks inherent in foreign investing. Adverse political, economic or social developments could undermine the value of the fund s investments or prevent the fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the US. Additionally, foreign securities markets generally are smaller and less liquid than US markets. Pricing risk. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different from the value realized upon such investment s sale. As a result, you could pay more than the market value when buying fund shares or receive less than the market value when selling fund shares. Securities lending risk. Any decline in the value of a portfolio security that occurs while the security is out on loan is borne by the fund and will adversely affect performance. Also, there may be delays in recovery of securities loaned or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the security. Operational and technology risk. Cyber-attacks, disruptions, or failures that affect the fund s service providers or counterparties, issuers of securities held by the fund, or other market participants may adversely affect the fund and its shareholders, including by causing losses for the fund or impairing fund operations. Active trading risk. Active securities trading could raise transaction costs (thus lowering returns) and could mean increased taxable distributions to shareholders and distributions that will be taxable to shareholders at higher federal income tax rates. PAST PERFORMANCE Since the fund commenced operations on October 5, 2015, performance information is not available for a full calendar year.

Fund Details ADDITIONAL INFORMATION ABOUT FUND STRATEGIES AND RISKS INVESTMENT OBJECTIVE The fund seeks to provide current income consistent with the preservation of capital and liquidity. PRINCIPAL INVESTMENT STRATEGY Main investments. The fund seeks to achieve its objective by investing mainly in high quality, short-term, US dollar denominated fixed-income instruments paying a fixed, variable or floating interest rate. These include: Debt obligations issued by US and foreign banks, financial institutions, corporations, municipalities or other entities, including certificates of deposit, euro-time deposits, commercial paper (including asset-backed commercial paper), notes and funding agreements. US government securities that are issued or guaranteed by the US Treasury, or by agencies or instrumentalities of the US government. Repurchase agreements, which are agreements to buy securities at one price, with a simultaneous agreement to sell back the securities at a future date at an agreedupon price. Asset-backed securities, which are generally participations in a pool of assets whose payment is derived from the payments generated by the underlying assets. Payments on asset-backed securities generally consist of interest and/or principal. Under normal circumstances, the fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, determined at the time of purchase, in high quality, short-term, US dollar denominated fixed-income instruments. For this purpose, high quality shall include short-term fixed-income instruments that are within the fund s credit quality guidelines. All instruments will be US dollar denominated, although they may be issued by a foreign bank or corporation, or a U.S. affiliate of a foreign bank or corporation, or a foreign government or its agencies. The fund may have significant exposure to obligations of banks and other financial institutions. The fund may invest no more than 5% of its total assets in any single issuer (other than cash and cash items, US government securities, repurchase agreements collateralized by these same securities, or securities of other investment companies). Credit Quality Guidelines. The short-term securities purchased by the fund (i) will have 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 security; or (ii) may 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 short-term categories; provided that, if the security has a long-term 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.

In certain situations, it may be difficult or impossible to sell an investment and/or the fund may sell certain investments at a price or time that is not advantageous in order to meet redemption requests or other cash needs. Unusual market conditions, such as an unusually high volume of redemptions or other similar conditions could increase liquidity risk for the fund. This risk can be ongoing for any security that does not trade actively or in large volumes, for any security that trades primarily on smaller markets, and for investments that typically trade only among a limited number of large investors (such as restricted securities). In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). This may affect only certain securities or an overall securities market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed-income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity. If dealer capacity in fixed-income markets is insufficient for market Prospectus December 1, 2016 6 Fund Details
conditions, it may further inhibit liquidity and increase volatility in the fixed-income markets. Additionally, market participants, other than the fund, may attempt to sell fixed income holdings at the same time as the fund, which could cause downward pricing pressure and contribute to illiquidity. 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 share price and yield and could hurt fund performance. Prepayments could also create capital gains tax liability in some instances. Security selection risk. The securities in the fund s portfolio may decline in value. Portfolio management could be wrong in its analysis of industries, companies, economic trends, the relative attractiveness of different securities or other matters. Focus risk. To the extent that the fund focuses its investments in particular industries, asset classes or sectors of the economy, any market price movements, regulatory or technological changes, or economic conditions affecting companies in those industries, asset classes or sectors may have a significant impact on the fund s performance. The fund may have significant exposure to obligations of banks and other financial institutions and market price movements, regulatory or technological changes, or economic conditions affecting such issuers could significantly impact the fund s performance. 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. 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. Foreign investment risk. The fund faces the risks inherent in foreign investing. Adverse political, economic or social developments could undermine the value of the fund s investments or prevent the fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the US. Additionally, foreign securities markets generally are smaller and less liquid than US markets. Pricing risk. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different from the value realized upon such investment s sale. As a result, you could pay more than the market value when buying fund shares or receive less than the market value when selling fund shares. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may prevent the fund from being able to realize full value and thus sell a security for its full valuation. This could cause a material decline in the fund s net asset value. Securities lending risk. Any decline in the value of a portfolio security that occurs while the security is out on loan is borne by the fund and will adversely affect performance. Also, there may be delays in recovery of securities loaned or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the security. Operational and technology risk. Cyber-attacks, disruptions, or failures that affect the fund s service providers or counterparties, issuers of securities held by the fund, or other market participants may adversely affect the fund and its shareholders, including by causing losses for the fund or impairing fund operations. Cyber-attacks may include unauthorized attempts by third parties to improperly access, modify, disrupt the operations of, or prevent access to the systems of the fund s service providers or counterparties, issuers of securities held by the fund or other market participants or data within them. In addition, power or communications outages, acts of god, information technology equipment malfunctions, operational errors, and inaccuracies within software or data processing systems may also disrupt business operations or impact critical data. Market events also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the fund s operations. Cyber-attacks, disruptions, or failures may adversely affect the fund and its shareholders or cause reputational damage and subject the fund to regulatory fines, litigation costs, penalties or financial losses, reimbursement or other compensation costs, and/or additional compliance costs. For example, the fund s or its service providers assets or sensitive or confidential information may be misappropriated, data may be corrupted, and operations may be disrupted (e.g., cyber-attacks or operational failures may cause the release of private shareholder information or confidential fund information, interfere with the processing of shareholder transactions, impact the ability Prospectus December 1, 2016 7 Fund Details
to calculate the fund s NAV, and impede trading). In addition, cyber-attacks, disruptions, or failures involving a fund counterparty could affect such counterparty s ability to meet its obligations to the fund, which may result in losses to the fund and its shareholders. Similar types of operational and technology risks are also present for issuers of securities held by the fund, which could have material adverse consequences for such issuers, and may cause the fund s investments to lose value. Furthermore, as a result of cyber-attacks, disruptions, or failures, an exchange or market may close or issue trading halts on specific securities or the entire market, which may result in the fund being, among other things, unable to buy or sell certain securities or financial instruments or unable to accurately price its investments. While the fund and its service providers may establish business continuity and other plans and processes that seek to address the possibility of and fallout from cyberattacks, disruptions, or failures, there are inherent limitations in such plans and systems, including that they do not apply to third parties, such as fund counterparties, issuers of securities held by the fund, or other market participants, as well as the possibility that certain risks have not been identified or that unknown threats may emerge in the future and there is no assurance that such plans and processes will address the possibility of and fallout from cyber-attacks, disruptions, or failures. In addition, the fund cannot directly control any cybersecurity plans and systems put in place by its service providers, fund counterparties, issuers of securities held by the fund, or other market participants. Active trading risk. Active securities trading could raise transaction costs (thus lowering returns) and could mean increased taxable distributions to shareholders and distributions that will be taxable to shareholders at higher federal income tax rates. OTHER POLICIES AND RISKS Although major changes tend to be infrequent, the fund s Board could change the fund s investment objective without seeking shareholder approval. However, the Board will provide shareholders with at least 60 days notice prior to making any changes to the fund s 80% investment policy as described herein. Portfolio management measures credit quality at the time it buys securities, using independent rating agencies or, for unrated securities, its own judgment. All securities must meet the credit quality standards applied by portfolio management at the time they are purchased. If a security s credit quality changes, portfolio management will decide what to do with the security, based on its assessment of what would most benefit the fund. The fund may trade actively. This could raise transaction costs (thus lowering return) and could mean increased taxable distributions to shareholders and distributions that will be taxable to shareholders at higher federal income tax rates.
