Invesco High Yield Municipal Fund

(formerly known as Invesco Van Kampen High Yield Municipal Fund)

 

Invesco High Yield Municipal Fund’s investment objective is to seek federal tax-exempt current income and taxable capital appreciation.

 

As with all other mutual fund securities, the Securities and Exchange Commission (SEC) has not approved or disapproved these securities or determined whether the information in this prospectus is adequate or accurate. Anyone who tells you otherwise is committing a crime.

 

An investment in the Fund:

n   is not FDIC insured;

n   may lose value; and

n   is not guaranteed by a bank.

 

 

 

        Invesco High Yield Municipal Fund

 

 

assets in industrial development bonds issued for companies in the same industry.

 

The Fund has no policy limiting its investments in municipal securities whose issuers are located in the same state. However, it is not the present intention of the Fund to invest more than 25% of the value of its net assets in issuers located in the same state.

 

The Fund may from time to time invest temporarily up to 20% of its net assets in taxable securities of at least comparable quality to the municipal securities in which the Fund invests. Under normal market conditions, the Fund may invest all or a substantial portion of its assets in municipal securities that are subject to the federal alternative minimum tax.

 

The Fund may invest up to 15% of its net assets in illiquid or thinly traded securities. The Fund may also invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933. The Fund’s investments may include securities that do not produce immediate cash income, such as zero coupon securities and payment-in-kind securities.

 

The Fund may purchase and sell securities on a when-issued and delayed delivery basis, which means that a Fund buys or sells a security with payment and delivery taking place in the future.

 

The Fund can invest in derivative instruments, including inverse floating rate municipal obligations, futures contracts and swap contracts.

 

The Fund can use inverse floating rate municipal obligations issued in connection with tender option bond programs to generate leverage.

 

The Fund can use futures contracts, including treasury futures, to gain or reduce exposure to certain asset classes.

 

The Fund can use swap contracts, including interest rate swaps, to hedge its exposure to interest rates.

 

The Adviser buys and sells securities for the Fund’s portfolio with a view towards seeking a high level of interest income exempt from federal income tax and selects securities that the Adviser believes entail reasonable credit risk considered in relation to the investment policies of the Fund. As a result, the Fund will not necessarily invest in the highest yielding municipal securities permitted by its investment policies if the Adviser determines that market risks or credit risks associated with such investments would subject the Fund’s portfolio to undue risk.

 

Decisions to purchase or sell securities are determined by the relative value considerations of the investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund’s macro risk exposure (such as duration, yield, curve positioning, sector exposure), a need to limit or reduce the Fund’s exposure to a particular security or issuer, degradation of an issuer’s credit quality, or general liquidity needs of the Fund. The potential for realization of capital gains or losses resulting from possible changes in interest rates will not be a major consideration and frequency of portfolio turnover generally will not be a limiting factor if the Adviser considers it advantageous to purchase or sell securities.

 

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 government 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:

 

Alternative Minimum Tax Risk. All or a portion of the Fund’s otherwise tax-exempt income may be taxable to those shareholders subject to the federal alternative minimum tax.

 

Call Risk. If interest rates fall, it is possible that issuers of debt securities with high interest rates will prepay or call their securities before their maturity dates. In this event, the proceeds from the called securities would likely be reinvested in securities bearing the new, lower interest rates, resulting in a possible decline in the Fund’s income and distributions to shareholders.

 

Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer’s credit rating.

 

Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index, commodity or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the Adviser elects not to do so due to availability, cost, market conditions or other factors.

 

High Yield Bond (Junk Bond) Risk. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time.

 

Income Risk. The income you receive from the Fund is based primarily on prevailing interest rates, which can vary widely over the short- and long-term. If interest rates drop, your income from the Fund may drop as well.

 

Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration.

 

Inverse Floating Rate Obligations Risk. Inverse floating rate obligations, including tender option bonds, may be subject to greater price volatility than a fixed income security with similar qualities. When short-term interest rates rise, they may decrease in value and produce less or no income. Additionally, these securities may lose principal. Similar to derivatives, inverse floating rate obligations have the following risks: counterparty, leverage, correlation, liquidity, market, interest rate, and management risks.

 

Leverage Risk. Leverage exists when the Fund purchases or sells an instrument or enters into a transaction without investing cash in an amount equal to the full economic exposure of the instrument or transaction and the Fund could lose more than it invested. Leverage created from borrowing or certain types of transactions or instruments may impair the Fund’s liquidity, cause it to liquidate positions at an unfavorable time, increase volatility or otherwise not achieve its intended objective.

 

Liquidity Risk. The Fund may hold illiquid securities that it is unable to sell at the preferred time or price and could lose its entire investment in such securities.

 

Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.

 

Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations.

 

Medium- and Lower-Grade Municipal Securities Risk. Securities which are in the medium- and lower-grade categories generally offer higher yields than are offered by higher-grade securities of similar maturity, but they also generally involve more volatility and greater risks, such as greater credit risk, market risk, liquidity risk, management risk, and regulatory risk. Furthermore, many medium- and lower-grade securities

 

2        Invesco High Yield Municipal Fund

are not listed for trading on any national securities exchange and many issuers of medium- and lower-grade securities choose not to have a rating assigned to their obligations by any nationally recognized statistical rating organization. As a result, the Fund’s portfolio may consist of a higher portion of unlisted or unrated securities as compared with an investment company that invests solely in higher-grade securities. Unrated securities are usually not as attractive to as many buyers as are rated securities, a factor which may make unrated securities less marketable. These factors may have the effect of limiting the availability of the securities for purchase by the Fund and may also limit the ability of the Fund to sell such securities at their fair value either to meet redemption requests or in response to changes in the economy or the financial markets.

 

Municipal Issuer Focus Risk. The Fund generally considers investments in municipal securities not to be subject to industry concentration policies (issuers of municipal securities as a group is not an industry) and the Fund may invest in municipal securities issued by entities having similar characteristics. The issuers may be located in the same geographic area or may pay their interest obligations from revenue of similar projects, such as hospitals, airports, utility systems and housing finance agencies. This may make the Fund’s investments more susceptible to similar social, economic, political or regulatory occurrences. As the similarity in issuers increases, the potential for fluctuation in the Fund’s net asset value also increases.

 

Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

 

Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond.

 

Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.

 

When-Issued and Delayed Delivery Risks. When-issued and delayed delivery transactions are subject to market risk as the value or yield of a security at delivery may be more or less than the purchase price or the yield generally available on securities when delivery occurs. In addition, the Fund is subject to counterparty risk because it relies on the buyer or seller, as the case may be, to consummate the transaction, and failure by the other party to complete the transaction may result in the Fund missing the opportunity of obtaining a price or yield considered to be advantageous.

 

Zero Coupon or Pay-In-Kind Securities Risk. The value, interest rates, and liquidity of non-cash paying instruments, such as zero coupon and pay-in-kind securities, are subject to greater fluctuation than other types of securities.

Tax Information

The Fund’s distributions primarily are exempt from regular federal income tax. A portion of these distributions, however, may be subject to the federal alternative minimum tax and state and local taxes. The Fund may also make distributions that are taxable to you as ordinary income or capital gains.

 

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 and 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 Web site for more information.

Investment Objective(s), Strategies, Risks and Portfolio Holdings

 

 

The Fund may purchase and sell securities on a when-issued and delayed delivery basis, which means that a Fund buys or sells a security with payment and delivery taking place in the future. The payment obligation and the interest rate are fixed at the time a Fund enters into the commitment. No income accrues on such securities until the date a Fund actually takes delivery of the securities.

 

The Fund can invest in derivative instruments, including inverse floating rate municipal obligations, futures contracts and swap contracts.

 

Inverse floating rate obligations are variable rate debt instruments that pay interest at rates that move in the opposite direction of prevailing interest rates. Because the interest rate paid to holders of such obligations is generally determined by subtracting a variable or floating rate from a predetermined amount, the interest rate paid to holders of such obligations will decrease as such variable or floating rate increases and increase as such variable or floating rate decreases. The Fund can use inverse floating rate municipal obligations issued in connection with tender option bond programs to generate leverage.

 

A futures contract is a standardized agreement between two parties to buy or sell a specific quantity of an underlying instrument or commodity at a specific price at a specific future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying instrument or commodity. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled by purchasing an offsetting contract, by physically delivering of the underlying instrument or commodity on the settlement date or paying a cash settlement amount on the settlement date. The Fund can use futures contracts, including treasury futures, to gain or reduce exposure to certain asset classes.

 

A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, commodities, currencies or other instruments. The notional amount of a swap is based on the nominal or face amount of a referenced asset that is used to calculate payments made on that swap; the notional amount typically is not exchanged between counterparties. The parties to the swap use variations in the value of the underlying asset to calculate payments between them through the life of the swap. The Fund can use swap contracts, including interest rate swaps, to hedge its exposure to interest rates.

 

The Adviser buys and sells securities for the Fund’s portfolio with a view towards seeking a high level of interest income exempt from federal income tax and selects securities that the Adviser believes entail reasonable credit risk considered in relation to the investment policies of the Fund. As a result, the Fund will not necessarily invest in the highest yielding municipal securities permitted by its investment policies if the Adviser determines that market risks or credit risks associated with such investments would subject the Fund’s portfolio to undue risk.

 

Decisions to purchase or sell securities are determined by the relative value considerations of the investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund’s macro risk exposure (such as duration, yield, curve positioning, sector exposure), a need to limit or reduce the Fund’s exposure to a particular security or issuer, degradation of an issuer’s credit quality, or general liquidity needs of the Fund. The potential for realization of capital gains or losses resulting from possible changes in interest rates will not be a major consideration and frequency of portfolio turnover generally will not be a limiting factor if the Adviser considers it advantageous to purchase or sell securities.

 

In anticipation of or in response to market, economic, political, or other conditions, the Adviser may temporarily use a different investment strategy for defensive purposes. If the Adviser does so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.

 

The Fund’s investments in the types of securities described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

 

For more information, see “Description of the Funds and Their Investments and Risks” in the SAI.

 

Risks

The principal risks of investing in the Fund are:

 

Alternative Minimum Tax Risk. Although the interest received from municipal securities general is exempt from federal income tax, the Fund may invest all or a substantial portion of its total assets in municipal securities subject to the federal alternative minimum tax. Accordingly, investment in the Fund could cause shareholders to be subject to (or result in an increased liability under) the federal alternative minimum tax.

 

Call Risk. If interest rates fall, it is possible that issuers of debt securities with high interest rates will prepay or call their securities before their maturity dates. In this event, the proceeds from the called securities would likely be reinvested by the Fund in securities bearing the new, lower interest rates, resulting in a possible decline in the Fund’s income and distributions to shareholders.

 

Credit Risk. The issuers of instruments in which the Fund invests may be unable to meet interest and/or principal payments. This risk is increased to the extent the Fund invests in junk bonds which may cause the Fund to incur higher expenses to protect its interests. The credit risks and market prices of lower-grade securities generally are more sensitive to negative issuer developments, such as reduced revenues or increased expenditures, or adverse economic conditions, such as a recession, than are higher-grade securities. An issuer’s securities may increase in value if its financial strength weakens, which may reduce its credit rating and possibly its ability to meet its contractual obligations. In the event that an issuer of securities held by the Fund experiences difficulties in the timely payment of principal and interest and such issuer seeks to restructure the terms of its borrowings, the Fund may incur additional expenses and may determine to invest additional assets with respect to such issuer or the project or projects to which the Fund’s securities relate. Further, the Fund may incur additional expenses to the extent that it is required to seek recovery upon a default in the payment of interest or the repayment of principal on its portfolio holdings and the Fund may be unable to obtain full recovery on such amounts.

 

Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index, commodity or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives.

 

5        Invesco High Yield Municipal Fund

 

Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the Adviser elects not to do so due to availability, cost, market conditions or other factors.

 

High Yield Bond (Junk Bond) Risk. Compared to higher quality debt securities, high yield bonds (commonly referred to as junk bonds) involve a greater risk of default or price changes due to changes in the credit quality of the issuer because they are generally unsecured and may be subordinated to other creditors’ claims. The values of junk bonds often fluctuate more in response to company, political, regulatory or economic developments than higher quality bonds. Their values can decline significantly over short periods of time or during periods of economic difficulty when the bonds could be difficult to value or sell at a fair price. Credit ratings on junk bonds do not necessarily reflect their actual market value.

 

Income Risk. The income you receive from the Fund is based primarily on prevailing interest rates, which can vary widely over the short- and long-term. If interest rates drop, your income from the Fund may drop as well.

 

Interest Rate Risk. Interest rate risk refers to the risk that municipal securities prices generally fall as interest rates rise; conversely, the prices generally rise as interest rates fall. Specific municipal securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. One measure of this sensitivity is called duration. The longer the duration of a particular municipal security, the greater its price sensitivity is to interest rates. Similarly, a longer duration portfolio of securities has greater price sensitivity. Falling interest rates may also prompt some issuers to refinance existing debt, which could affect the Fund’s performance. Volatility may be greater during periods of general economic uncertainty. A significant increase in interest rates or a general economic downturn could severely disrupt the market for medium- and lower-grade securities and adversely affect the market value of such securities.

 

Inverse Floating Rate Obligations Risk. The value of inverse floating rate obligations, including tender option bonds, will decrease as interest rates increase. Furthermore, the coupon rate on an inverse floating rate obligation typically changes at a multiple of the change in the relevant index rate. Thus, the Fund also has correlation risk. Some inverse floating rate obligations may also increase or decrease substantially because of changes in the rate of prepayments. Inverse floating rate obligations have varying degrees of liquidity based on the underlying securities in the special purpose trust. Additionally, these securities may lose principal. Therefore, inverse floating rate obligations may be more volatile than other fixed income securities. The Fund generally invests in inverse floating rate obligations that include embedded leverage, thus exposing the Fund to greater risks and increased costs. The market value of a “leveraged” inverse floating rate obligations generally will fluctuate in response to changes in market rates of interest to a greater extent than the value of an unleveraged investment. The use of short-term floating rate obligations may require the Fund to segregate or earmark cash or liquid assets to cover its obligations. Securities so segregated or earmarked will be unavailable for sale be the Fund (unless replaced by other securities qualifying for segregation requirements), which may limit the Fund’s flexibility and may require that the Fund sell other portfolio investments at a time when it may be disadvantageous to sell such assets.

 

Leverage Risk. Borrowing money to buy securities exposes the Fund to leverage because the Fund can achieve a return on a capital base larger than the assets that shareholders have contributed to the Fund. Certain other transactions may give rise to a form of leverage. Leverage also exists when the Fund purchases or sells an instrument or enters into a transaction without investing cash in an amount equal to the full economic exposure of the instrument or transaction and the Fund could lose more than it invested. Except in the case of borrowing, the Fund mitigates leverage risk by segregating or earmarking liquid assets or otherwise covers transactions that may give rise to such risk. To the extent that the Fund is not able to close out a leveraged position because of market illiquidity, the Fund’s liquidity may be impaired to the extent that it has a substantial portion of liquid assets segregated or earmarked to cover obligations and may liquidate portfolio positions when it may not be advantageous to do so. Leveraging may cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. There can be no assurance that the Fund’s leverage strategy will be successful.

 

Liquidity Risk. The markets for medium- and lower-grade securities may be less liquid than the markets for higher-grade securities. Certain municipal securities, in which the Fund may invest, such as special obligation bonds, lease obligations, participation certificates and variable

 

6        Invesco High Yield Municipal Fund

rate instruments, may be particularly less liquid. A security is considered to be illiquid if the Fund is unable to sell such security at a fair price within a reasonable amount of time. A security may be deemed illiquid due to a lack of sufficient trading volume in the security or if the security is privately placed and not traded in any public market or is otherwise restricted from trading. The Fund may be unable to sell illiquid securities at the time or price it desires and could lose its entire investment in such securities or may have to sell other securities instead to obtain cash or forego other investment opportunities. Further, to the extent the Fund owns or may acquire illiquid or restricted medium- and lower-grade securities, these securities may involve special registration responsibilities, liabilities and costs, and liquidity and valuation difficulties.

 

Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results.

 

Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations.

 

Medium- and Lower-Grade Municipal Securities Risk. Securities which are in the medium- and lower-grade categories generally offer higher yields than are offered by higher-grade securities of similar maturity, but they also generally involve more volatility and greater risks, such as greater credit risk, market risk, liquidity risk, management risk, and regulatory risk. Furthermore, many medium- and lower-grade securities are not listed for trading on any national securities exchange and many issuers of medium- and lower-grade securities choose not to have a rating assigned to their obligations by any nationally recognized statistical rating organization. As a result, the Fund’s portfolio may consist of a higher portion of unlisted or unrated securities as compared with an investment company that invests solely in higher-grade securities. Unrated securities are usually not as attractive to as many buyers as are rated securities, a factor which may make unrated securities less marketable. These factors may have the effect of limiting the availability of the securities for purchase by the Fund and may also limit the ability of the Fund to sell such securities at their fair value either to meet redemption requests or in response to changes in the economy or the financial markets.

 

Municipal Issuer Focus Risk. The Fund generally considers investments in municipal securities not to be subject to industry concentration policies (issuers of municipal securities as a group is not an industry) and the Fund may invest in municipal securities issued by entities having similar characteristics. The issuers may be located in the same geographic area or may pay their interest obligations from revenue of similar projects, such as hospitals, airports, utility systems and housing finance agencies. This may make the Fund’s investments more susceptible to similar social, economic, political or regulatory occurrences. As the similarity in issuers increases, the potential for fluctuation in the Fund’s net asset value also increases. From time to time, the Fund’s investments may include securities as to which the Fund, by itself or together with other funds or accounts managed by the Adviser, holds a major portion or all of an issue of municipal securities. Because there may be relatively few potential purchasers for such investments and, in some cases, there may be contractual restrictions on resales, the Fund may find it more difficult to sell such securities at a time when the Adviser believes it is advisable to do so.

 

Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Revenue bonds are generally not backed by the taxing power of the issuing municipality. To the extent that a municipal security is not heavily followed by the investment community or such security issue is relatively small, the security may be difficult to value or sell at a desirable price. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

 

Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. If interest rates decline, the underlying bond may rise in value, but the cash flows received from that bond may have to be reinvested at a lower interest rate.

 

Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.

 

When-Issued and Delayed Delivery Risks. When-issued and delayed delivery transactions are subject to market risk as the value or yield of a security at delivery may be more or less than the purchase price or the yield generally available on securities when delivery occurs. In addition, the Fund is subject to counterparty risk because it relies on the buyer or seller, as the case may be, to consummate the transaction, and failure by the other party to complete the transaction may result in the Fund missing the opportunity of obtaining a price or yield considered to be advantageous.

 

Zero Coupon or Pay-In-Kind Securities Risk. Zero coupon and pay-in-kind securities may be subject to greater fluctuation in value and less liquidity in the event of adverse market conditions than comparably rated securities paying cash interest at regular interest payment periods. Prices on non-cash-paying instruments may be more sensitive to changes in the issuer’s financial condition, fluctuation in interest rates and market demand/supply imbalances than cash-paying securities with similar credit ratings, and thus may be more speculative. Investors may purchase zero coupon and pay-in-kind securities at a price below the amount payable at maturity. Because such securities do not entitle the holder to any periodic payments of interest prior to maturity, this prevents any reinvestment of interest payments at prevailing interest rates if prevailing interest rates rise. On the other hand, because there are no periodic interest payments to be reinvested prior to maturity, zero coupon securities eliminate the reinvestment risk and may lock in a favorable rate of return to maturity if interest rates drop. Special tax considerations are associated with investing in certain lower-grade securities, such as zero coupon or pay-in-kind securities.

9        Invesco High Yield Municipal Fund

 

In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s returns over a 10-year period. The example reflects the following:

 

There is no assurance that the annual expense ratio will be the expense ratio for the Fund classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

In addition to the Fund(s), the Adviser serves as investment adviser to many other Invesco mutual funds that are offered to retail investors (Invesco Funds or Funds). The following information is about all of the Invesco Funds that offer retail share classes.

 

Some investments in the Funds are made through accounts that are maintained by intermediaries (and not in the name of an individual investor) and some investments are made indirectly through products that use the Funds as underlying investments, such as Retirement and Benefit Plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the Funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the name of an individual investor), the intermediary or conduit investment vehicle may impose rules that differ from, and/or charge a transaction or other fee in addition to, those described in this prospectus. Please consult your financial adviser or other financial intermediary for details.

 

Unless otherwise provided, the following are certain defined terms used throughout this prospectus:

Go to the tab for “Accounts & Services,” then click on “Service Center,” or consult the Fund’s prospectus and SAI, which are available on that same Web site or upon request free of charge. The Web site is not part of this prospectus.

 

Choosing a Share Class

Each Fund may offer multiple classes of shares and not all Funds offer all share classes discussed herein. Each class represents an interest in the same portfolio of investments. Certain classes have higher expenses than other classes which may lower the return on your investment when compared to a less expensive class. In deciding which class of shares to purchase, you should consider the following attributes of the various share classes, among other things: (i) the eligibility requirements that apply to purchases of a particular class, (ii) the initial sales charges and contingent deferred sales charges (CDSCs), if any, applicable to the class, (iii) the 12b-1 fee, if any, paid by the class, and (iv) any services you may receive from a financial intermediary. Please contact your financial adviser to assist you in making your decision. Please refer to the prospectus fee table for more information on the fees and expenses of a particular Fund’s share classes.

 

 

 

In addition to the share classes shown in the chart above, the following Funds offer the following additional share classes:

 

A-1        The Invesco Funds

MCF—06/13

 

Share Class Eligibility

 

Class A, B, C and Invesco Cash Reserve Shares

Class A, C and Invesco Cash Reserve Shares are available to all retail investors, including individuals, trusts, corporations, business and charitable organizations and Retirement and Benefit Plans. The share classes offer different fee structures that are intended to compensate financial intermediaries for services provided in connection with the sale of shares and continued maintenance of the customer relationship. You should consider the services provided by your financial adviser and any other financial intermediaries who will be involved in the servicing of your account when choosing a share class.

 

Class B shares are closed to new and to additional investors. Existing shareholders of Class B shares may continue as Class B shareholders, continue to reinvest dividends and capital gains distributions in Class B shares and exchange their Class B shares for Class B shares of other Funds as permitted by the current exchange privileges, until they convert. For Class B shares outstanding on November 29, 2010 and Class B shares acquired upon reinvestment of dividends, all Class B share attributes including the associated Rule 12b-1 fee, CDSC and conversion features, will continue.

 

Class A2 Shares

Class A2 shares, which are offered only on Invesco Limited Maturity Treasury Fund and Invesco Tax-Free Intermediate Fund, are closed to new investors. All references in this prospectus to Class A shares shall include Class A2 shares, unless otherwise noted.

 

Class AX, BX, CX and RX Shares

Class AX, BX, CX and RX shares are closed to new investors. Only investors who have continuously maintained an account in Class AX, CX or RX of a specific Fund may make additional purchases into Class AX, CX and RX, respectively, of such specific Fund. All references in this Prospectus to Class A, B, C or R shares of the Invesco Funds shall include Class AX (excluding Invesco Money Market Fund), BX, CX, or RX shares, respectively, of the Invesco Funds, unless otherwise noted. All references in this Prospectus to Invesco Cash Reserve Shares of Invesco Money Market Fund shall include Class AX shares of Invesco Money Market Fund, unless otherwise noted.

 

Class P Shares

In addition to the other share classes discussed herein, the Invesco Summit Fund offers Class P shares, which were historically sold only through the AIM Summit Investors Plans I and II (each a Plan and, collectively, the Summit Plans). Class P shares are sold with no initial sales charge and have a 12b-1 fee of 0.10%. However, Class P shares are not sold to members of the general public. Only shareholders who had accounts in the Summit Plans at the close of business on December 8, 2006 may purchase Class P shares and only until the total of their combined investments in the Summit Plans and in Class P shares directly equals the face amount of their former Plan under the 30 year extended investment option. The face amount of a Plan is the combined total of all scheduled monthly investments under the Plan. For a Plan with a scheduled monthly investment of $100.00, the face amount would have been $36,000.00 under the 30 year extended investment option.

 

Class R Shares

Class R shares are intended for eligible Employer Sponsored Retirement and Benefit Plans.

 

Class S Shares

Class S shares are limited to investors who purchase shares with the proceeds received from a systematic contractual investment plan redemption within the 12 months prior to purchasing Class S shares, and who purchase through an approved financial intermediary that has an agreement with the distributor to sell Class S shares. Class S shares are not otherwise sold to members of the general public. An investor purchasing Class S shares will not pay an initial sales charge. The investor will no longer be eligible to purchase additional Class S shares at that point where the value of the contributions to the prior systematic contractual investment plan combined with the subsequent Class S share contributions equals the face amount of what would have been the investor’s systematic contractual investment plan under the 30-year investment option. The face amount of a systematic contractual investment plan is the combined total of all scheduled monthly investments under that plan. For a plan with a scheduled monthly investment of $100.00, the face amount would have been $36,000.00 under the 30-year extended investment option.

 

Class Y Shares

Class Y shares are available to (i) investors who purchase through a fee-based advisory account with an approved financial intermediary, (ii) defined contribution plans, defined benefit retirement plans, endowments or foundations, (iii) banks or bank trust departments acting on their own behalf or as trustee or manager for trust accounts, or (iv) any current, former or retired trustee, director, officer or employee (or immediate family members of a current, former or retired trustee, director, officer or employee) of any Invesco Fund or of Invesco Ltd. or any of its subsidiaries. In fee-based advisory programs, a financial intermediary typically charges each investor a fee based on the value of the investor’s account in exchange for servicing that account. Class Y shares are not available for IRAs or Employer Sponsored IRAs.

 

Subject to any conditions or limitations imposed on the servicing of Class Y shares by your financial adviser, if you received Class Y shares as a result of a merger or reorganization of a predecessor fund into any of the Funds, you will be permitted to make additional Class Y share purchases.

 

Investor Class Shares

Some of the Funds offer Investor Class shares.  Investor Class shares are sold with no initial sales charge and have a maximum 12b-1 fee of 0.25%. Only the following persons may purchase Investor Class shares:

 

Distributors to compensate or reimburse, as applicable, Invesco Distributors for its efforts in connection with the sale and distribution of the Fund’s shares and for services provided to shareholders, all or a substantial portion of which are paid to the dealer of record. Because the Funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cause you to pay more than the maximum permitted initial sales charges described in this prospectus.

 

The following Funds and share classes do not have 12b-1 plans:

 

Under the applicable distribution plan or distribution plan and service plan, the Funds may pay distribution and service fees up to the following amounts with respect to each Fund’s average daily net assets with respect to such class:

 

Please refer to the prospectus fee table for more information on a particular Fund’s 12b-1 fees.

 

Initial Sales Charges (Class A Shares Only)

The Funds are grouped into four categories for determining initial sales charges. The “Other Information” section of each Fund’s prospectus will tell you the sales charge category in which the Fund is classified. As used below, the term “offering price” with respect to all categories of Class A shares includes the initial sales charge.

 

If you purchase $1,000,000 or more of Class A shares of Category I or II Funds or $500,000 or more of Class A shares of Category IV Funds (a Large Purchase) the initial sales charge set forth below will be waived; though your shares will be subject to a 1% CDSC if you don’t hold such shares for at least 18 months.

 

 

 

 

 

Class A Shares Sold Without an Initial Sales Charge

The following types of investors may purchase Class A shares without paying an initial sales charge:

 

In addition, investors may acquire Class A shares without paying an initial sales charge in connection with:

 

A-3        The Invesco Funds

 

Invesco Distributors also permits certain other investors to invest in Class A shares without paying an initial charge as a result of the investor’s current or former relationship with the Invesco Funds. For additional information about such eligibility, please reference the Funds’ SAI.

 

In all instances, it is the purchaser’s responsibility to notify Invesco Distributors or the purchaser’s financial intermediary of any relationship or other facts qualifying the purchaser as eligible to purchase Class A shares without paying an initial sales charge and to provide all necessary documentation of such facts.

 

It is possible that a financial intermediary may not, in accordance with its policies and procedures, be able to offer one or more of these waiver categories. If this situation occurs, it is possible that the investor would need to invest directly through Invesco Distributors in order to take advantage of the waiver. The Funds may terminate or amend the terms of these sales charge waivers at any time.

 

Qualifying for Reduced Sales Charges and Sales Charge Exceptions

The following types of accounts qualify for reduced sales charges or sales charge exceptions under Rights of Accumulation (ROAs) and Letters of Intent (LOIs). These types of accounts are referred to as “ROA/LOI Eligible Purchasers”:

 

Alternatively, an Employer Sponsored Retirement and Benefit Plan or Employer Sponsored IRA may be considered a ROA eligible purchaser at the plan level, and receive a reduced applicable initial sales charge for a new purchase based on the total value of the current purchase and the value of other shares owned by the plan’s participants if:

 

Participant accounts in a retirement plan that is a ROA eligible purchaser at the plan level may not also be considered a ROA eligible purchaser for the benefit of an individual account owner.

 

In all instances, it is the purchaser’s responsibility to notify Invesco Distributors or the purchaser’s financial intermediary of any relationship or other facts qualifying the purchaser as eligible for reduced sales charges and/or sales charge exceptions and to provide all necessary documentation of such facts in order to qualify for reduced sales charges or sales charge exceptions. For additional information on linking accounts to qualify for ROA or LOI, please see the Funds’ SAI.

 

Purchases of Class A shares of Invesco Tax-Exempt Cash Fund or Invesco Cash Reserve Shares of Invesco Money Market Fund or Investor Class shares of any Fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to ROAs or LOIs.

 

Rights of Accumulation

Purchasers that qualify for ROA may combine new purchases of Class A shares of a Fund with shares of the Fund or other open-end Invesco Funds currently owned (Class A, B, C, IB, IC, P, R, S or Y) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase will be based on the total of your current purchase and the value of other shares owned based on their current public offering price. The Funds’ transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates.

 

Letters of Intent

Under a LOI, you commit to purchase a specified dollar amount of Class A shares of one or more Funds during a 13-month period. The amount you agree to purchase determines the initial sales charge you pay. If the full amount committed to in the LOI is not invested by the end of the 13-month period, your account will generally be assessed the higher initial sales charge that would normally be applicable to the total amount actually invested.

 

Reinstatement Following Redemption

If you redeem any class of shares of a Fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any Fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B, P and S redemptions may be reinvested into Class A shares without an initial sales charge and Class Y and Class R redemptions may be reinvested into Class A shares without an initial sales charge or Class Y or Class R shares.

 

This reinstatement privilege does not apply to a purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account.

 

This reinstatement privilege shall be suspended for the period of time in which a purchase block is in place on a shareholder’s account. Please see “Purchase Blocking Policy” discussed below.

 

In order to take advantage of this reinstatement privilege, you must inform your financial adviser or the Funds’ transfer agent that you wish to do so at the time of your reinvestment.

 

Contingent Deferred Sales Charges (CDSCs)

 

CDSCs on Class A Shares and Invesco Cash Reserve Shares of Invesco Money Market Fund

Any shares of a Large Purchase of Class A shares redeemed prior to 18 months after the date of purchase will be subject to a CDSC of 1%.

 

If Invesco Distributors pays a concession to a financial intermediary in connection with a Large Purchase of Class A shares by an Employer Sponsored Retirement and Benefit Plan or Employer Sponsored IRA, the Class A shares will be subject to a 1% CDSC if all of the Employer Sponsored Retirement and Benefit Plan’s or Employer Sponsored IRA’s shares are redeemed within one year from the date of initial purchase.

 

If you acquire Invesco Cash Reserve Shares of Invesco Money Market Fund or Class A shares of Invesco Tax-Exempt Cash Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.
