A contingent deferred sales charge may apply in some cases. See "Shareholder Account Information-Contingent Deferred Sales Charges (CDSCs)."

Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive a portion of the Fund's management fee in an amount equal to the net management fee that Invesco earns on the Fund's investments in certain affiliated funds, which will have the effect of reducing the Acquired Fund Fees and Expenses. Unless Invesco continues the fee waiver agreement, it will terminate on June 30, 2024. During its term, the fee waiver agreement cannot be terminated or amended to reduce the advisory fee waiver without approval of the Board of Trustees.

**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. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

**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 rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 88% of the average value of its portfolio.

**Principal Investment Strategies of the Fund**

The Fund invests mainly in debt securities, including foreign and U.S. government bonds and notes, mortgage-related securities, corporate debt obligations, including lower-grade, high-yield domestic and foreign corporate debt obligations, "structured" notes, participation interests in loans, investments in pooled investment entities (including those that invest in loans), asset-backed securities and "zero coupon" and "stripped" securities.

Under normal market conditions, the Fund invests a substantial portion of its assets in a number of different countries, including the U.S. The Fund is not required to allocate its investments in any set percentages in any particular countries. The Fund's foreign investments may include debt securities of issuers in both developed and emerging markets. The Fund has no limitations regarding the range of maturities of the debt securities it can buy or the market capitalization of the issuers of those securities.

The Fund can invest in investment grade or lower-grade, high-yield debt securities. "Investment grade" debt securities are rated in one of the top four rating categories by nationally recognized statistical rating organizations such as Moody's Investors Service or S&P Global Ratings (S&P). The Fund may also invest in unrated securities, in which case the investment adviser may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the investment adviser's credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization. Although the Fund normally invests a substantial portion of its assets in lower-grade, high-yield debt securities, it can buy investment-grade debt securities without limit. The Fund may also invest in certain restricted securities and securities exempt from registration under the Securities Act of 1933 (Securities Act) including securities that are only eligible for resale pursuant to Rule 144A under the Securities Act (referred to as Rule 144A Securities).

The Fund can enter into "forward roll" transactions (also referred to as "mortgage dollar rolls") with respect to mortgage-related securities. A substantial portion of the Fund's assets may be subject to forward roll transactions at any given time.

The Fund may also use derivatives for investment purposes or hedging, including options, futures, forward contracts, swaps and "structured" notes. The Fund actively manages foreign currency exposure, both to reduce risk and to seek to enhance return. To do so, the Fund may invest in foreign exchange derivatives, including forwards and options that reference foreign currencies, including currencies of developing and emerging market countries.

The portfolio managers analyze the overall investment opportunities and risks across global fixed income markets in which the Fund invests and seek to moderate the special risks of investing in lower-grade, high-yield debt instruments and foreign securities by building a broadly diversified portfolio. The Fund's diversification strategies are intended to help reduce share price volatility while seeking current income. The portfolio managers currently focus on securities offering a balance of income and total return, securities whose market prices tend to move in different directions (to seek overall portfolio diversification), and relative values across global fixed income markets. These factors may vary in particular cases and may change over time. The Fund may sell securities that the portfolio managers believe are no longer favorable with regard to these factors.

The Fund may invest up to 25% of its total assets in a Cayman Islands exempted company that is wholly-owned and controlled by the Fund (the Subsidiary). The Subsidiary invests in Regulation S securities. Regulation S securities are securities of U.S. and non-U.S. issuers that are issued through private offerings without registration with the Securities and Exchange Commission pursuant to Regulation S under the Securities Act of 1933. The Fund applies its investment restrictions and compliance policies and procedures, on a look-through basis, to the Subsidiary. Since the Fund may invest a substantial portion of its assets in the Subsidiary, which may hold certain of the investments described in this prospectus, the Fund may be considered to be investing indirectly in those investments through its Subsidiary. Therefore, references in this prospectus to investments by the Fund also may be deemed to include the Fund's indirect investments through the Subsidiary.

**Principal Risks of Investing in the Fund** 

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

***Market Risk****.* The market values of the Fund's investments, and therefore the value of the Fund's shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund's investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

***Debt Securities Risk****.* The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities.

**2 Invesco Global Strategic Income Fund**

**invesco.com/us**O-GLSI-SUMPRO-1

------

Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund's distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer's financial strength, the market's perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser's credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.

***Changing Fixed Income Market Conditions Risk****.* Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund's investments and share price may decline. Changes in central bank policies could also result in higher than normal redemptions by shareholders, which could potentially increase the Fund's portfolio turnover rate and transaction costs.

***High Yield Debt Securities (Junk Bond) Risk****.* Investments in high yield debt securities ("junk bonds") and other lower-rated securities will subject the Fund to substantial risk of loss. These securities are considered to be speculative with respect to the issuer's ability to pay interest and principal when due, are more susceptible to default or decline in market value and are less liquid than investment grade debt securities. Prices of high yield debt securities tend to be very volatile.

***Foreign Government Debt Risk****.* Investments in foreign government debt securities (sometimes referred to as sovereign debt securities) involve certain risks in addition to those relating to foreign securities or debt securities generally. The issuer of the debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due in accordance with the terms of such debt, and the Fund may have limited recourse in the event of a default against the defaulting government. Without the approval of debt holders, some governmental debtors have in the past been able to reschedule or restructure their debt payments or declare moratoria on payments.

***Mortgage- and Asset-Backed Securities Risk****.* Mortgage- and asset-backed securities, including collateralized debt obligations and collateralized mortgage obligations, are subject to prepayment or call risk, which is the risk that a borrower's payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. This could result in the Fund reinvesting these early payments at lower interest rates, thereby reducing the Fund's income. Mortgage- and asset-backed securities also are subject to extension risk, which is the risk that an unexpected rise in interest rates could reduce the rate of prepayments, causing the price of the mortgage- and asset-backed securities and the Fund's share price to fall. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of mortgage-backed securities and could result in losses to the Fund. Privately-issued mortgage-backed securities and asset-backed securities may be less liquid than other types of securities and the Fund may be unable to sell these securities at the time or price it desires. During periods of market stress or high redemptions, the Fund may be forced to sell these securities at significantly reduced prices, resulting in losses. Liquid privately-issued mortgage-backed securities and asset-backed securities can become illiquid during periods of market stress. Privately-issued mortgage-related securities are not subject to the same underwriting requirements as those with government or government-sponsored entity guarantees and, therefore, mortgage loans underlying privately-issued

mortgage-related securities may have less favorable collateral, credit risk, liquidity risk or other underwriting characteristics, and wider variances in interest rate, term, size, purpose and borrower characteristics. The Fund may invest in mortgage pools that include subprime mortgages, which are loans made to borrowers with weakened credit histories or with lower capacity to make timely payments on their mortgages. Liquidity risk is even greater for mortgage pools that include subprime mortgages.

***Foreign Securities Risk****.* The Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls, and may therefore be more susceptible to fraud or corruption. There may be less public information available about foreign companies than U.S. companies, making it difficult to evaluate those foreign companies. Unless the Fund has hedged its foreign currency exposure, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful.

***Emerging Market Securities Risk****.* Emerging markets (also referred to as developing markets) are generally subject to greater market volatility, political, social and economic instability, uncertain trading markets and more governmental limitations on foreign investment than more developed markets. In addition, companies operating in emerging markets may be subject to lower trading volume and greater price fluctuations than companies in more developed markets. Such countries' economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund's ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions (including bankruptcy, confiscatory taxation, expropriation, nationalization of a company's assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures and practices such as share blocking), or to obtain information needed to pursue or enforce such actions, may be limited. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

***Geographic Focus Risk****.* The Fund may from time to time have a substantial amount of its assets invested in securities of issuers located in a single country or a limited number of countries. Adverse economic, political or social conditions in those countries may therefore have a significant negative impact on the Fund's investment performance.

***LIBOR Transition Risk****.* The Fund may have investments in financial instruments that utilize the London Interbank Offered Rate ("LIBOR") as the reference or benchmark rate for variable interest rate calculations. LIBOR is intended to measure the rate generally at which banks can lend and borrow from one another in the relevant currency on an unsecured basis.

**3 Invesco Global Strategic Income Fund**

**invesco.com/us**O-GLSI-SUMPRO-1

------

Regulators and financial industry working groups in several jurisdictions have worked over the past several years to identify alternative reference rates ("ARRs") to replace LIBOR and to assist with the transition to the new ARRs. For example, the Federal Reserve Bank of New York has identified the Secured Overnight Financing Rate ("SOFR") as the intended replacement to USD LIBOR and foreign regulators have proposed other interbank offered rates, such as the Sterling Overnight Index Average ("SONIA") and other replacement rates, which could also be adopted. Consequently, the publication of most LIBOR rates ceased at the end of 2021, but a selection of widely used USD LIBOR rates continues to be published until June 2023 to allow for an orderly transition away from these rates. Additionally, key regulators have instructed banking institutions to cease entering into new contracts that reference these USD LIBOR settings after December 31, 2021, subject to certain limited exceptions.

There remains uncertainty and risks relating to the continuing LIBOR transition and its effects on the Fund and the instruments in which the Fund invests. For example, there can be no assurance that the composition or characteristics of any ARRs or financial instruments in which the Fund invests that utilize ARRs will be similar to or produce the same value or economic equivalence as LIBOR or that these instruments will have the same volume or liquidity. Additionally, although regulators have generally prohibited banking institutions from entering into new contracts that reference those USD LIBOR settings that continue to exist, there remains uncertainty and risks relating to certain "legacy" USD LIBOR instruments that were issued or entered into before December 31, 2021 and the process by which a replacement interest rate will be identified and implemented into these instruments when USD LIBOR is ultimately discontinued. The effects of such uncertainty and risks in "legacy" USD LIBOR instruments held by the Fund could result in losses to the Fund.

***U.S. Government Obligations Risk****.* Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund's ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

***Small- and Mid-Capitalization Companies Risk****.* Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Stocks of small- and mid-capitalization companies tend to be

more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies' securities may be more volatile and less liquid than those of more established companies. They may be more sensitive to changes in a company's earnings expectations and may experience more abrupt and erratic price movements. Smaller companies' securities often trade in lower volumes and in many instances, are traded over-the-counter or on a regional securities exchange, where the frequency and volume of trading is substantially less than is typical for securities of larger companies traded on national securities exchanges. Therefore, the securities of smaller companies may be subject to wider price fluctuations and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. It may take a substantial period of time to realize a gain on an investment in a small- or mid-cap company, if any gain is realized at all.

***Subsidiary Risk****.* By investing in the Subsidiary, the Fund is indirectly exposed to risks associated with the Subsidiary's investments. The Subsidiary is not registered under the Investment Company Act of 1940, as amended (1940 Act), and, except as otherwise noted in this prospectus, is not subject to the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary, respectively, are organized, could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the SAI, and could negatively affect the Fund and its shareholders.

***Regulation S Securities Risk***. Regulation S securities may be less liquid than publicly traded securities and may not be subject to the disclosure and other investor protection requirements that would be applicable if they were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

***Rule 144A Securities and Other Exempt Securities Risk***. The market for Rule 144A and other securities exempt from certain registration requirements typically is less active than the market for publicly-traded securities. Rule 144A and other exempt securities, which are also known as privately issued securities, carry the risk that their liquidity may become impaired and the Fund may be unable to dispose of the securities at a desirable time or price.

***Exchange-Traded Funds Risk****.* In addition to the risks associated with the underlying assets held by the exchange-traded fund, investments in exchange-traded funds are subject to the following additional risks: (1) an exchange-traded fund's shares may trade above or below its net asset value; (2) an active trading market for the exchange-traded fund's shares may not develop or be maintained; (3) trading an exchange-traded fund's shares may be halted by the listing exchange; (4) a passively managed exchange-traded fund may not track the performance of the reference asset; and (5) a passively managed exchange-traded fund may hold troubled securities. Investment in exchange-traded funds may involve duplication of management fees and certain other expenses, as the Fund indirectly bears its proportionate share of any expenses paid by the exchange-traded funds in which it invests. Further, certain exchange-traded funds in which the Fund may invest are leveraged, which may result in economic leverage, permitting the Fund to gain exposure that is greater than would be the case in an unlevered instrument and potentially resulting in greater volatility.

***Investment Companies Risk****.* Investing in other investment companies could result in the duplication of certain fees, including management and administrative fees, and may expose the Fund to the risks of owning the underlying investments that the other investment company holds.

------

***Senior Loans and Other Loans Risk***. Risks associated with an investment in Senior Loans include credit risk, interest rate risk, liquidity risk, valuation risk and prepayment risk. These risks are typically associated with debt securities but may be heightened in part because of the limited public information regarding Senior Loans. Senior Loans generally are floating rate loans, which are subject to interest rate risk as the interest paid on the floating rate loans adjusts periodically based on changes in widely accepted reference rates. Lack of an active trading market, restrictions on resale, irregular trading activity, wide bid/ask spreads and extended trade settlement periods may impair the Fund's ability to sell Senior Loans within its desired time frame or at an acceptable price and its ability to accurately value existing and prospective investments. Extended trade settlement periods may result in cash not being immediately available to the Fund. As a result, the Fund may have to sell other investments or engage in borrowing transactions to raise cash to meet its obligations. The risk of holding Senior Loans is also directly tied to the risk of insolvency or bankruptcy of the issuing banks. The value of Senior Loans can be affected by and sensitive to changes in government regulation and to economic downturns in the United States and abroad. Senior loans are also subject to the risk that a court could subordinate a senior loan or take other action detrimental to the holders of senior loans. Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. Loan investments are often issued in connection with highly leveraged transactions which are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy. Highly leveraged loans also may be less liquid than other loans. These risks could cause the Fund to lose income or principal on a particular investment, which in turn could affect the Fund's returns.

***Financial Markets Regulatory Risk***. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund's operations, universe of potential investment options, and return potential.

***Money Market Fund Risk****.* Although money market funds generally seek to preserve the value of an investment at $1.00 per share, the Fund may lose money by investing in money market funds. A money market fund's sponsor has no legal obligation to provide financial support to the money market fund. The credit quality of a money market fund's holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the money market fund's share price. A money market fund's share price can also be negatively affected during periods of high redemption pressures, illiquid markets and/or significant market volatility.

***Management Risk****.* The Fund is actively managed and depends heavily on the Adviser's judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund's portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

**Performance Information**

The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Global Strategic Income Fund (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the "Reorganization"). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the predecessor fund and the Fund from year to year as of December 31.

The performance table compares the predecessor fund's and the Fund's performance to that of a broad measure of market performance.

The Fund's (and the predecessor fund's) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. The returns shown for periods ending on or prior to May 24, 2019 are those of the Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund. Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund were reorganized into Class A, Class C, Class R, Class Y and Class R6 shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C, Class R, Class Y and Class R6 shares' returns of the Fund will be different from the returns of the predecessor fund as they have different expenses. Performance for Class A shares has been restated to reflect the Fund's applicable sales charge. Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable-fee waivers and expense reimbursements.

Updated performance information is available on the Fund's website at www.invesco.com/us.

Performance shown prior to the inception date is that of the predecessor fund's Class A shares at net asset value and includes the 12b-1 fees applicable to that class. Although invested in the same portfolio of securities, Class R5 shares' returns of the Fund will be different from Class A shares' returns of the predecessor fund as they have different expenses.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans, 529 college savings plans or individual retirement accounts. After-tax returns are shown for Class A shares only and after-tax returns for other classes will vary.

With respect to Class R5 and Class R6 shares, there is no minimum initial investment for Employer Sponsored Retirement and Benefit Plans investing through a retirement platform that administers at least $2.5 billion in retirement plan assets. All other Employer Sponsored Retirement and Benefit Plans must meet a minimum initial investment of at least $1 million in each Fund in which it invests.

For all other institutional investors purchasing Class R5 or Class R6 shares, the minimum initial investment in each share class is $1 million, unless such investment is made by (i) an investment company, as defined under the Investment Company Act of 1940, as amended (1940 Act), that is part of a family of investment companies which own in the aggregate at least $100 million in securities, or (ii) an account established with a 529 college savings plan managed by Invesco, in which case there is no minimum initial investment.

There are no minimum investment amounts for Class R6 shares held through retail omnibus accounts maintained by an intermediary, such as a broker, that (i) generally charges an asset-based fee or commission in addition to those described in this prospectus, and (ii) maintains Class R6 shares and makes them available to retail investors.

**Tax Information** 

The Fund's distributions generally are taxable to you as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan, 529 college savings plan or individual retirement account. Any distributions from a 401(k) plan or individual retirement account may be taxed as ordinary income when withdrawn from such plan or account.

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund, the Fund's distributor or its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the

broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary's website for more information.
