Dear Shareholder,

On June 1, Invesco completed its acquisition of Morgan Stanley’s retail asset management business, including Van Kampen Investments.

The Invesco and Van Kampen/Morgan Stanley retail investment capabilities were highly complementary, enabling Invesco to provide a more balanced product offering to Invesco Funds’ shareholders. As a result of the combination, Invesco gained investment talent for a number of investment strategies, including U.S. Value Equity, U.S. Small Cap Growth Equity, Tax-Free Municipals, Bank Loans and others. With this enhanced expertise and a comprehensive range of diverse investment capabilities, Invesco is better positioned than ever to meet the needs of investors across the U.S. and around the globe.

Since June 1, Invesco has been conducting a comprehensive review of its product line to sharpen its offerings to investors. A key goal of this effort is to reduce overlap and enhance efficiency across the product line for the benefit of Invesco Funds’ shareholders and Invesco.

As the next step in the process of integrating the combined business, the Invesco Funds Boards have approved a realignment of fund offerings, subject to shareholder approval. If approved by shareholders, the proposed realignment will:

	§		Distinguish and emphasize Invesco’s most compelling investment processes and strategies;

	§		Reduce overlap in the product lineup to help lower costs for shareholders; and

	§		Build a solid foundation for further growth to meet client and shareholder needs.

In addition, most Funds will continue to be managed by their existing investment management teams post-reorganization and many shareholders will experience a reduction in total expense ratio, decreasing the cost of their investment. In cases where management fee expenses are scheduled to increase as a result of a proposed reorganization, Invesco has instituted a cap on the total expense ratio of the Acquiring Fund intended to preserve the lowest current expense ratio of all Target Funds in each proposed set of reorganizations for a period of time post reorganization.

The independent trustees of your Board believe that the reorganization proposed in this proxy is in the best interest of your Fund and the attached proxy seeks your vote in favor of the proposed reorganization.

Your vote is important. Please take a moment after reviewing the enclosed materials to sign and return your proxy card in the enclosed postage paid return envelope. If you attend the meeting, you may vote your shares in person. If you expect to attend the meeting in person, or have questions, please notify us by calling 1-800-959-4226. You may also vote your shares by telephone or through a website established for that purpose by following the instructions that appear on the enclosed proxy card.

PROXY STATEMENT/PROSPECTUS
_____________, 2011

Introduction

This Proxy Statement/Prospectus contains information that shareholders of the Invesco Van Kampen High Yield Fund (the “Target Fund”), a series of AIM Investment Securities Funds (Invesco Investment Securities Funds) (the “Trust”) should know before voting on the proposed reorganization that is described herein, and should be retained for future reference. This document is both the proxy statement of the Target Fund and also a prospectus for the Invesco High Yield Fund (the “Acquiring Fund”), which is also a series of the Trust. The Target Fund and the Acquiring Fund are series of a registered open-end management investment company. The Target Fund and the Acquiring Fund together are referred to as the “Funds” and to each fund individually as a “Fund.”

A special meeting of the shareholders of the Target Fund (the “Meeting”) will be held at 11 Greenway Plaza, Suite 2500, Houston, Texas 77046 on April 14, 2011 at 3:00 p.m., Central time. At the Meeting, shareholders of the Target Fund are being asked to consider the following proposal:

To approve an Agreement and Plan of Reorganization between the Target Fund and the Acquiring Fund, providing for: (a) the acquisition of all of the assets and assumption of all of the liabilities of the Target Fund by the Acquiring Fund in exchange for shares of a corresponding class of the Acquiring Fund; (b) the distribution of such shares of the corresponding class to the shareholders of the Target Fund; and (c) the liquidation and termination of the Target Fund (the “Reorganization”).

The total value of the Acquiring Fund shares of each class that shareholders will receive in the Reorganization will be the same as the total value of the shares of each class of the Target Fund that shareholders held immediately prior to the Reorganization. The Reorganization is anticipated to be a tax-free transaction, meaning that shareholders should not be required to pay any federal income tax in connection with the Reorganization. No sales charges or redemption fees will be imposed in connection with the Reorganization.

The Board of Trustees of the Trust (the “Board”) has fixed the close of business on January 14, 2011 as the record date (“Record Date”) for the determination of shareholders entitled to notice of and to vote at the Meeting and at any adjournment thereof. Shareholders of the Target Fund on the Record Date will be entitled to one vote for each share of the Target Fund held (and a proportionate fractional vote for each fractional share). This Proxy Statement/Prospectus, the enclosed Notice of Special Meeting of Shareholders and the enclosed proxy card will be mailed on or about January __, 2011 to all shareholders eligible to vote on the Reorganization.

The Board has approved the Agreement and Plan of Reorganization and has determined that the Reorganization is in the best interest of the Target Fund and the Acquiring Fund and will not dilute the interests of the existing shareholders of the Target Fund or the Acquiring Fund. If shareholders of the Target Fund do not approve the Reorganization, the Board will consider what further action is appropriate for that Fund.

Additional information about the Funds is available in the:

	•		Prospectuses for the Target Fund and the Acquiring Fund;

	•		Annual and semi-annual reports to shareholders of the Target Fund and the Acquiring Fund; and

PROPOSAL: TO APPROVE AN AGREEMENT AND PLAN OF REORGANIZATION

Shareholders of the Target Fund are being asked to consider and approve an Agreement and Plan of Reorganization (the “Agreement”) that will have the effect of reorganizing the Target Fund with and into the Acquiring Fund, as summarized below. The Agreement provides for (a) the acquisition of all of the assets and assumption of all of the liabilities of the Target Fund by the Acquiring Fund in exchange for shares of a corresponding class of the Acquiring Fund; (b) the distribution of such shares of the corresponding class to the shareholders of the Target Fund; and (c) the liquidation and termination of the Target Fund.

SUMMARY OF KEY INFORMATION

The following is a summary of certain information contained elsewhere in this Proxy Statement/Prospectus, in the Agreement, and/or in the prospectuses and SAIs of the Funds. Shareholders should read the entire Proxy Statement/Prospectus and the prospectus of the Acquiring Fund carefully for more complete information.

On what am I being asked to vote?

As a shareholder of the Target Fund, you are being asked to consider and vote to approve the Agreement under which the assets and liabilities of the Target Fund will be transferred to the Acquiring Fund.

If shareholders of the Target Fund approve the Agreement, shares of each class of the Target Fund will be exchanged for Acquiring Fund shares of the corresponding class of equal value, which will result in your holding shares of the Acquiring Fund equal to the value of your shares of the corresponding class of the Target Fund, and the Target Fund will be liquidated and terminated.

Has my Fund’s Board of Trustees approved the Reorganization?

Yes. The Board has carefully reviewed the proposal and unanimously approved the Agreement and the Reorganization. The Board recommends that shareholders of the Target Fund vote in favor of the Agreement.

What are the reasons for the proposed Reorganization?

On June 1, 2010, Invesco Ltd. (“Invesco”), the indirect parent company of Invesco Advisers, Inc., the Funds’ investment adviser (“Invesco Advisers” or “Adviser”), acquired the retail mutual fund business of Morgan Stanley, which included 92 Morgan Stanley and Van Kampen branded funds. This transaction filled gaps in Invesco’s product line-up and has enabled the company to expand its investment offerings to retail customers. The transaction also resulted in significant product overlap. The Reorganization proposed in this Proxy Statement/Prospectus is part of a larger group of reorganizations across Invesco’s mutual fund platform. The reorganizations are designed to put forth Invesco’s most compelling investment processes and strategies, reduce product overlap and create scale in the resulting funds to help reduce the shareholders’ cost of ownership.

In considering the Reorganization and Agreement, the Board considered these and other factors in concluding that the Reorganizations would be in the best interest of the Funds. The Board’s considerations are described in more detail in the “THE PROPOSED REORGANIZATION — Board Considerations in Approving the Reorganizations” section below.

What effect will the Reorganization have on me as a shareholder?

Immediately after the Reorganization, you will hold shares of a class of the Acquiring Fund that are equal in value to the shares of the corresponding class of the Target Fund that you held immediately prior to the closing of the Reorganization. The principal differences between the Target Fund and the Acquiring Fund are described in this Proxy Statement/Prospectus. The prospectus of the Acquiring Fund that accompanies this Proxy Statement/Prospectus contains additional information about the Acquiring Fund that you will hold shares of following the Reorganization, if approved.

How do the Funds’ investment objectives, principal investment strategies and risks compare?

The Acquiring Fund and the Target Fund have similar investment objectives, as described below. Each Fund’s investment objective is classified as non-fundamental, which means that it can be changed by the Board without shareholder approval, although there is no present intention to do so.

Investment Objectives


Target Fund		Acquiring Fund
The Fund’s primary investment objective is to seek to maximize current income. Capital appreciation is a secondary objective which is sought only when consistent with the Fund’s primary objective.		The Fund’s investment objective is total return, comprised of current income and capital appreciation.

The principal investment strategies of the Acquiring Fund are similar to the principal investment strategies of the Target Fund, although the Acquiring Fund may invest in different types of investments and have different investment policies and limitations than the Target Fund. As a result, the risks of owning shares of the Acquiring Fund are similar to the risks of owning shares of the Target Fund, although the risks of the Funds may not be exactly the same. The sections below entitled “ADDITIONAL INFORMATION ABOUT THE FUNDS — Comparison of Principal Investment Strategies” and “Comparison of the Principal Risks of Investing in the Funds” compare the principal investment strategies and risks of the Target Fund and the Acquiring Fund and highlight certain key differences.

How do the Funds’ expenses compare?

The tables below provide a summary comparison of the expenses of the Target Fund and the Acquiring Fund, as well as estimated expenses on a pro forma basis giving effect to the proposed Reorganization. The pro forma expense ratios show projected estimated expenses but actual expenses may be greater or less than those shown.

*		Expense ratios reflect annual fund operating expenses for the most recent fiscal year (as disclosed in a Funds’ current prospectuses) of the Target Fund (August 31, 2010) and the Acquiring Fund (February 28, 2010). Pro forma numbers are estimated as if the Reorganization had been completed as of August 1, 2009 and do not include the estimated costs of the Reorganization. The Target Fund is not expected to bear any Reorganization costs. For more information on the costs of the Reorganization to be borne by the Funds, see “Costs of the Reorganization” below.

1.		You may be charged a 2.00% fee if you redeem or exchange shares of the Fund within 31 days of purchase.

2.		Based on estimated amounts for the current fiscal year.

3.		The Acquiring Fund’s Adviser has contractually agreed, through at least June 30, 2011, to waive advisory fees and/or reimburse expenses of all shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed below) of Class A shares to 0.99%, Class B shares to 1.74%, Class C shares to 1.74%, and Class Y shares to 0.74% of average daily net assets, respectively. Unless the Board of Trustees and Invesco Advisers, Inc. mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2011.

4.		Effective upon the closing of the Reorganization, Invesco Advisers has contractually agreed, through at least June 30, 2013, to waive advisory fees and/or reimburse expenses of all shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed below) of Class A shares to 0.89%, Class B shares to 1.64%, Class C shares to 1.64% and Class Y shares to 0.64% of average daily net assets. In determining the Adviser’s obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to exceed the limit reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items; and (v) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Unless the Board and Invesco Advisers mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2013.

Expense Example

This Example is intended to help you compare the costs of investing in different classes of the Target Fund and the Acquiring Fund with the cost of investing in other mutual funds. Pro forma combined costs of investing in different classes of the Acquiring Fund after giving effect to the reorganization of the Target Fund into the Acquiring Fund are also provided. All costs are based upon the information set forth in the Fee Table above.

The Example assumes that you invest $10,000 for the time periods indicated and shows the expenses that you would pay if you redeem all of your shares at the end of those time periods. The Example also assumes that your investment has a 5% return each year and that the operating expenses remain the same. The Example reflects fee waivers and/or expense reimbursements that are contractual, if any, but does not reflect voluntary fee waivers and/or expense reimbursements. To the extent fees are waived and/or expenses are reimbursed on a voluntary basis, your expenses will be lower. Although your actual returns and costs may be higher or lower, based on these assumptions your costs would be:

The Example is not a representation of past or future expenses. The Target Fund’s and Acquiring Fund’s actual expenses, and an investor’s direct and indirect expenses, may be more or less than those shown. The table and the assumption in the Example of a 5% annual return are required by regulations of the SEC applicable to all mutual funds. The 5% annual return is not a prediction of and does not represent the Target Fund’s or Acquiring Fund’s projected or actual performance.

For further discussion regarding the Board’s consideration of the fees and expenses of the Funds in approving the Reorganization, see the section entitled “THE PROPOSED REORGANIZATION - Board Considerations in Approving the Reorganization” in this Proxy Statement/Prospectus.

How do the performance records of the Funds compare?

Fund as of September 30, 2010. Other classes of shares that are not presented would have had substantially similar annual returns because the shares are invested in the same portfolio of securities and the annual returns will differ only to the extent that the classes do not have the same expenses. The prospectuses for the Funds contain additional performance information under the headings “Performance Information” and “Financial Highlights.” Additional performance information and a discussion of performance are also included in each Fund’s most recent annual report to shareholders.

¹		The returns shown for periods prior to June 1, 2010 are those of the Class A shares of a predecessor fund that was advised by Van Kampen Asset Management and was reorganized into the Target Fund on June 1, 2010. The returns shown for periods after June 1, 2010 are those of the Target Fund. The returns of the Target Fund are different from the predecessor fund as they had different expenses and sales charges.

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-deferred arrangements, such as 401(k) plans or individual retirement accounts.

How do the management, investment manager and other service providers of the Funds compare?

Each Fund is overseen by the same Board and officers. In addition, Invesco Advisers, a registered investment adviser, serves as primary investment adviser for each Fund pursuant to an investment advisory agreement that contains substantially identical terms (except for fees) for each Fund. The contractual investment advisory fee of the Acquiring Fund is higher than the contractual investment advisory fee of the Target Fund. See the section of this Proxy Statement/Prospectus entitled “SUMMARY OF KEY INFORMATION — How do the Funds’ expenses compare?” for more information about fees. Invesco Advisers is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. Invesco Advisers has acted as an investment adviser since its organization in 1976. As of September 30, 2010, Invesco Advisers had $300.3 billion under management. Invesco Advisers is an indirect, wholly owned subsidiary of Invesco.

The advisory agreement applicable to the Funds provides that Invesco Advisers may delegate any and all of its rights, duties and obligations to one or more wholly owned affiliates of Invesco as sub-advisers (the “Invesco Sub-Advisers”). Pursuant to Master Intergroup Sub-Advisory Contracts, the Invesco Sub-Advisers may be appointed by Invesco Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to a Fund. The Invesco Sub-Advisers, each of which is an indirect, wholly owned subsidiary of Invesco and a registered investment adviser under the Investment Advisers Act of 1940, are:


•	Invesco Asset Management Deutschland GmbH;	•	Invesco Hong Kong Limited;
•	Invesco Asset Management Limited;	•	Invesco Asset Management (Japan) Limited;
•	Invesco Australia Limited;	•	Invesco Senior Secured Management, Inc.; and
•	Invesco Trimark Ltd.

Other key service providers to the Target Fund, including the administrator, transfer agent, custodian, distributor and auditor, provide the same or substantially the same services to the Acquiring Fund. The Acquiring Fund’s prospectus and SAI describe the services and other arrangements with these service providers.

How do the Funds’ purchase and redemption procedures, distribution policies and exchange policies compare?

The sales charges, sales charge exemptions, distribution and servicing arrangements, purchase and redemption procedures, redemption fees, and exchange policies are generally similar. For more information see the section entitled “Comparison of Share Classes and Distribution Arrangements.”

Will the Acquiring Fund have different portfolio managers than the Target Fund?

Yes. The portfolio management teams of the Target Fund and the Acquiring Fund are similar but the Acquiring Fund has an additional member of its portfolio management team who is not a member of the portfolio management team of the Target Fund. The Acquiring Fund prospectus that accompanies this Proxy Statement/Prospectus provides biographical information about the key individuals that comprise the portfolio management team for the Acquiring Fund.

Will there be any tax consequences resulting from the proposal?

The Reorganization is designed to qualify as a tax-free reorganization for federal income tax purposes and the Target Fund anticipates receiving a legal opinion to that effect. Thus, while there can be no guarantee that the Internal Revenue Service (“IRS”) will adopt a similar position, it is expected that shareholders will have no adverse federal income tax consequences as a result of the Reorganization. Shareholders should consult their tax adviser about state and local tax consequences of the Reorganization, if any, because the information about tax consequences in the Proxy Statement/Prospectus relates to the federal income tax consequences of the Reorganization only.

When is the Reorganization expected to occur?

If shareholders of the Target Fund approve the Reorganization, it is anticipated that such Reorganization will occur on or about May 2, 2011.

How do I vote on the Reorganization?

There are several ways you can vote your shares, including in person at the Meeting by mail, by telephone or via the Internet. The proxy card that accompanies this Proxy Statement/Prospectus provides detailed instructions on how you may vote your shares. If you properly fill in and sign your proxy card and send it to us in time to vote at the Meeting, your “proxy” (the individuals named on your proxy card) will vote your shares as you have directed. If you sign your proxy card but do not make specific choices, your proxy will vote your shares FOR the proposal, as recommended by the Board, and in their best judgment on other matters.

What will happen if shareholders of a Target Fund do not approve the Reorganization?

If the shareholders of the Target Fund do not approve the Reorganization, the Target Fund’s Board will consider other possible courses of action for the Target Fund.

What if I do not wish to participate in the Reorganization?

If you do not wish to have your shares of your Target Fund exchanged for shares of the Acquiring Fund as part of the Reorganization that is approved by shareholders, you may redeem your shares prior to the consummation of the Reorganization. If you redeem your shares, you will incur any applicable deferred sales charge and if you hold shares in a taxable account, you will recognize a taxable gain or loss based on the difference between your tax basis in the shares and the amount you receive for them.

Why are you sending me the Proxy Statement/Prospectus?

ADDITIONAL INFORMATION ABOUT THE FUNDS

Comparison of Principal Investment Strategies

The following section compares the principal investment strategies of the Target Fund with the principal investment strategies of the Acquiring Fund and highlights any key differences. In addition to the principal investment strategies described below, each Fund is also subject to certain additional investment policies and limitations, which are described in each Fund’s prospectus and SAI. The cover page of this Proxy Statement/Prospectus describes how you can obtain copies of these documents. A comparison of the principal risks associated with the Funds’ investment strategies is described below under “Comparison of Principal Risks of Investing in the Funds.”

The investment strategies of the Acquiring Fund and the Target Fund are similar. The Acquiring Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for investment purposes) in debt securities that are determined to be below investment grade quality. Under normal market conditions, the Target Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in high yield, high risk corporate bonds at the time of investment.

The Acquiring Fund considers debt securities to be below investment grade quality if they are rated BB/Ba or lower by Standard & Poor’s Ratings Services, Moody’s Investors Service, Inc., or any other nationally recognized statistical rating organization (NRSRO), or are determined by the portfolio managers to be of comparable quality to such rated securities. These types of securities are commonly known as “junk bonds.” The Acquiring Fund will principally invest in junk bonds rated B or above by an NRSRO or deemed to be of comparable quality by the portfolio managers. The Target Fund buys and sells medium- and lower-grade securities with a view towards seeking a high level of current income and capital appreciation over the long-term. In addition to high-yielding, high-risk bonds, the Target Fund may invest in other income securities, such as convertible securities and preferred stock.

The Acquiring Fund may invest up to 25% of its total assets in foreign securities. The Acquiring Fund may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. The Acquiring Fund may also invest up to 15% of its total assets in securities of issuers located in developing markets. The Target Fund may invest a portion or all of its total assets in securities issued by foreign governments or foreign corporations; provided, however, that the Fund may not invest more than 30% of its total assets in non-U.S. dollar denominated securities.

In attempting to meet its investment objective, the Acquiring Fund may engage in active and frequent trading of portfolio securities.

In selecting securities for the Acquiring Fund’s portfolio, the portfolio managers focus on junk bonds that they believe have favorable prospects for high current income and the possibility of growth of capital. Before purchasing securities for the Fund, the portfolio managers conduct a bottom-up fundamental analysis of an issuer that involves an evaluation by a team of credit analysts of an issuer’s financial condition. The fundamental analysis is supplemented by (i) an ongoing review of the securities’ relative value compared with other junk bonds, and (ii) a top-down analysis of sector and macro-economic trends.

The portfolio managers attempt to control the Acquiring Fund’s risk by (i) limiting the portfolio’s assets that are invested in any one security, and (ii) diversifying the portfolio’s holdings over a number of different industries. The Target Fund also invests in a broad range of income securities represented by various companies and industries and traded on various markets. In selecting securities for investment for the Target Fund, the Adviser seeks to identify securities which entail reasonable credit risk considered in relation to the Fund’s investment policies. The Adviser uses an investment strategy of fundamental credit analysis and emphasizes issuers that they believe will remain financially sound and perform well in a range of market conditions.

Under normal market conditions, the Target Fund invests at least 65% of its total assets in corporate bonds and other income securities, such as convertible securities and preferred stock, with maturities greater than one year.

The Target Fund may purchase and sell options, futures contracts, options on futures contracts, swaps and structured products, which are derivative instruments, for various portfolio management purposes and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index.

Comparison of Principal Risks of Investing in the Funds

The table below describes the principal risks that may affect each Fund’s investment portfolio. For more information on the risks associated with the Acquiring Fund, see the “Investment Strategies and Risks” section of the Acquiring Fund’s SAI.


Principal Risk		Funds Subject to Risk
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.		Acquiring Fund Target Fund

Active Trading Risk. The Fund may engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.		Acquiring Fund

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.		Acquiring Fund Target Fund

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

Call Risk. If interest rates fall, it is possible that issuers of income securities with high interest rates will prepay or “call” their securities before their maturity dates. In this event, the proceeds from these 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.		Target Fund

Foreign Securities Risk. The value of the Fund’s foreign investments may be adversely affected by changes in the foreign country’s exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.		Acquiring Fund Target Fund


Principal Risk		Funds Subject to Risk
Developing Markets Securities Risk. Securities issued by foreign companies and governments located in developing countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.		Acquiring Fund

Risks of Using Derivative Instruments. Risks of derivatives include imperfect correlation between the value of the instruments and the underlying assets; risks of default by the other party to certain transactions; risks that the transactions may result in losses that partially or completely offset gains in portfolio positions; and risks that the transactions may not be liquid.		Target Fund

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.		Acquiring Fund Target Fund

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.		Acquiring Fund Target Fund

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

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.		Acquiring Fund Target Fund

Comparison of Fundamental and Non-Fundamental Investment Restrictions

Each Fund has adopted fundamental investment restrictions concerning, among other things, diversification of the Fund’s investment portfolio, concentration in particular industries, borrowing and loaning money, and investing in real estate and commodities. Fundamental investment restrictions of a Fund cannot be changed without shareholder approval. The fundamental and non-fundamental investment restrictions of the Target Fund and those of the Acquiring Fund are the same. Non-fundamental investment restrictions of a Fund can be changed by a Fund’s Board.

Both the Target Fund and the Acquiring Fund may be subject to other investment restrictions that are not identified above. A full description of the Target Fund’s and the Acquiring Fund’s investment policies and restrictions may be found in their respective SAIs.

Comparison of Share Classes and Distribution Arrangements

Each share class of the Target Fund will be reorganized into a specific share class of the Acquiring Fund. The following sub-sections identify the Acquiring Fund share class that corresponds with the Target Fund share class as well as the different distribution arrangements among the various share classes.

Class Structure. The Funds each offer multiple share classes. Each such class offers a distinct structure of sales charges, distribution and/or service fees, and reductions and waivers thereto, which are designed to address a variety of shareholder servicing needs. In addition, some share classes have certain eligibility requirements that must be met to invest in that class of shares. The eligibility requirements are the same for each Fund and are described in the Funds’ prospectuses.

The share classes offered by the Target Fund and the corresponding share classes of the Acquiring Fund that Target Fund shareholders will receive in connection with the Reorganization are as follows:


Target Fund Share Classes		Acquiring Fund Share Classes
Class A		Class A
Class B		Class B
Class C		Class C
Class Y		Class Y
Institutional Class		Institutional Class

Neither Fund currently offers Class B shares to new investors. Existing investors of the Target Fund that owned Class B shares before their closure will continue to receive reinvested dividends in the form of new Class B shares but may no longer add to their existing positions in Class B shares. Shareholders who receive Class B shares in connection with the Reorganization may continue to hold those shares and reinvest dividends until the scheduled conversion date of the Class B shares to Class A shares but may not purchase new Class B shares.

Sales Charges. The sales charge schedule (if any) of each share classes of the Target Fund are substantially the same as the sales charge schedule (if any) of the corresponding share classes of the Acquiring Fund. Class A shares of each Fund are sold with an initial sales charge that ranges from 4.75% to zero depending on the amount of your investment. Class B and Class C shares of each Fund are sold with a contingent deferred sales charge that may be imposed when the shares are sold. Class A shares may also be subject to a contingent deferred sales charge on purchases of $1 million or more if redeemed prior to 18 months after the date of purchase. Each Fund offers reductions and waivers of the initial sales charge and contingent deferred sale charge to certain eligible investors or under certain circumstances, which are substantially the same between the Funds. Class Y shares are sold without any initial sales charge or contingent deferred sales charge. Each share class except Class Y and Institutional Class imposes an asset based sales charge or service fee under one or more planss adopted by the Board, which are described in the following section. The Funds’ prospectuses describe the sales charge schedules and applicable waivers and exemptions of each such share class.

You will not pay an initial sales charge on Acquiring Fund Class A shares that you receive in connection with the Reorganization. In addition, the exchange of Class A shares, Class B shares or Class C shares of the Target Fund for corresponding classes of the Acquiring Fund at the consummation of the Reorganization will not result in the imposition of any contingent deferred sales charge that applies to those share classes. Upon consummation of the Reorganization, former Target Fund shareholders of Class A shares, Class B shares or Class C shares will be credited for the period of time from their original date of purchase of the Target Fund Class A shares, Class B shares or Class C shares for purposes of determining the amount of any contingent deferred sales charge that may be due upon subsequent redemption, if any. In addition, the CDSC schedule that applies to the Class B shares of the Target Fund that you own will continue to apply to the Class B shares of the Acquiring Fund that you receive in the Reorganization. The Acquiring Fund initial sales charges for Class A shares and contingent deferred sales charges that apply to Class A shares and Class C shares will apply to any Class A shares or Class C shares of the Acquiring Fund purchased after the Reorganization, unless you are eligible for a reduction or waiver of the initial sales charge or contingent deferred sales charge.

Distribution Fees. The Funds have adopted distribution plans and service plans (together, the “Distribution Plans”) pursuant to Rule 12b-1 under the Investment Company Act of 1940, as amended, (the “1940 Act”) with respect to each of their Class A, Class B and Class C shares. Class Y and Institutional Class shares of the Funds are not subject to the Distribution Plans.

Pursuant to the Target Fund’s Distribution Plan, a Target Fund is authorized to make payments to Invesco Distributors, Inc., (“IDI”), the Funds’ principal underwriter in connection with the distribution of Target Fund shares and providing shareholder services at the annual rate of up to 0.25% of the Target Fund’s average daily net assets attributable to Class A shares, and at the annual rate of up to 1.00% of the Target Fund’s average daily net assets attributable to Class B and Class C shares. Notwithstanding the foregoing expense limits, however, IDI may be reimbursed from a Target Fund only up to the amount it has spent on activities or expenses primarily intended to result in the sale of shares or the servicing of shareholders. This type of Distribution Plan is sometimes referred to as a “reimbursement-type” plan because the underwriter is only entitled to be reimbursed for its plan-related expenses.

The Distribution Plans for the Acquiring Fund and the Target Fund are similar, except that the IDI is entitled to be paid by an Acquiring Fund the maximum amounts described above (i.e., 0.25% for Class A shares and

1.00% for Class B and Class C shares) regardless of the amount IDI has spent on activities or expenses intended to result in the sale of shares or the servicing of shareholders. This type of Distribution Plan is sometimes referred to as a “compensation-type” plan because the underwriter is compensated at a fixed rate, regardless of its actual distribution and service-related expenditures. Thus it is possible that under the Acquiring Fund’s Distribution Plan the underwriter could, in practice, receive payments in excess of the amounts actually paid under the Target Fund’s “reimbursement type” Distribution Plan.

The fee table under the “SUMMARY OF KEY INFORMATION — How do the Funds’ expenses compare” section of this Proxy Statement/Prospectus describes the fees paid under each Fund’s Distribution Plan for a recent period as well as the fees to be paid under the Acquiring Fund’s Distribution Plan following the Reorganization.

Comparison of Purchase and Redemption Procedures

The purchase procedures employed by the Target Fund and the Acquiring Fund are substantially the same. Each Fund offers shares through its distributor on a continuous basis. Shares of the Funds may be purchased directly through the transfer agent and through other authorized financial intermediaries. Investors may purchase both initial and additional shares by mail, wire, telephone or the internet. The Acquiring Fund prospectus enclosed with this Proxy Statement/Prospectus describes in detail how shareholders can purchase Acquiring Fund shares. Class A, Class B (closed to new investments, except dividend reinvestments), Class C, Class Y and Investor Class shares of the Funds require a minimum investment of $1,000 ($250 for IRA, Roth IRA, and Coverdell Education Savings Accounts). Institutional Class shares of the Target Fund and the Acquiring Fund each require a minimum initial investment that ranges from $0 to $10 million, depending on the type of account making the investment. The Acquiring Fund’s prospectus describes the types of accounts to which the minimum initial investment applies. For accounts participating in a systematic investment program, the minimum investment is $50 ($25 for IRA, Roth IRA, and Coverdell Education Savings Accounts). Certain exemptions apply as set forth in the Funds’ prospectuses. The foregoing investment minimums will not apply to shares received in connection with the Reorganization. However, investors may be charged a small-account fee if account balances remain below the required investment minimum for certain periods. See the Funds’ prospectuses for details.

Redemption Fees

The Target Fund and the Acquiring Fund each charge a 2% redemption fee on shares that are redeemed within 31 days of purchase. The redemption fee for a Fund is intended to compensate the Fund for the increased expenses to longer-term shareholders and the disruptive effect on the Fund’s portfolio caused by short-term investments in a Fund. This redemption fee is retained by the Fund.

The exchange of Target Fund shares for Acquiring Fund shares at the consummation of the Reorganization will not result in the imposition of any redemption fee that applies to Target Fund shares. Acquiring Fund shares received in the Reorganization may be subject to a redemption fee if redeemed within 31 days of purchase of the Target Fund shares that were exchanged for such Acquiring Fund shares. New shares of the Acquiring Fund purchased after the Reorganization will be subject to the Acquiring Fund’s redemption fee. The redemption fee will be waived on sales or exchanges of the Target Fund and the Acquiring Fund shares under certain circumstances, which are described in the Target Fund’s and Acquiring Fund’s prospectus. Additional information relating to redemption fees is available in the Target Fund’s and Acquiring Fund’s prospectuses.

Comparison of Distribution Policies

The Target Fund declares dividends of net investment income, if any, daily, and pays them monthly. The Acquiring Fund declares and pays dividends of net investment income, if any, monthly. Each Fund declares and pays capital gains distributions, if any, at least annually. Each Fund may also declare and pay capital gains distributions more than once per year as permitted by law. Each Fund automatically reinvests any dividends from net investment income or capital gains distributions, unless otherwise instructed by a shareholder to pay dividends and distributions in cash.

Forms of Organization and Securities to be Issued

The Target Fund and the Acquiring Fund are each a series of the same Delaware statutory trust with the same governing instruments, including the declaration of trust and bylaws. As a result, there are no material differences between the rights of shareholders under the governing state laws of the Target Fund and the Acquiring Fund. Each share of the Acquiring Fund represents an equal proportionate interest with each other share of the Fund, and each such share is entitled to equal dividend, liquidation, redemption and voting rights, except where class voting is required by the Trust’s governing instruments, the Board or applicable law, in which case shareholders of a class will have exclusive voting rights on matters affecting only that class. The assets and liabilities of each Fund are legally separate from the assets and liabilities of any other fund that is a series of the Trust. More information about the voting, dividend and other rights associated with shares of the Funds can be found in the Funds’ SAI.

Pending Litigation

Civil lawsuits, including a regulatory proceeding and purported class action and shareholder derivative suits, have been filed against certain Invesco Funds, INVESCO Funds Group, Inc. (“IFG”) (the former investment adviser to certain Funds), a predecessor to Invesco Advisers, IDI and/or related entities and individuals, depending on the lawsuit, alleging among other things: (i) that the defendants permitted improper market timing and related activity in the funds; and (ii) that certain funds inadequately employed fair value pricing. You can find more detailed information concerning all of the above matters, including the parties to the civil lawsuits and summaries of the various allegations and remedies sought in such lawsuits, in the Acquiring Fund’s SAI.

Where to Find More Information

For more information with respect to each Fund concerning the following topics, please refer to the following sections of the Funds’ prospectuses: (i) see “Fund Management” for more information about the management of a Fund; (ii) see “Other Information” for more information about a Fund’s policy with respect to dividends and distributions; and (iii) see “Shareholder Account Information” for more information about the pricing, purchase, redemption and repurchase of shares of a Fund, tax consequences to shareholders of various transactions in shares of a Fund, and distribution arrangements of a Fund.

THE PROPOSED REORGANIZATION

Summary of Agreement and Plan of Reorganization

The terms and conditions under which the Reorganization may be consummated are set forth in the Agreement. Significant provisions of the Agreement are summarized below; however, this summary is qualified in its entirety by reference to the form of Agreement, a copy of which is attached as Exhibit D to this Proxy Statement/Prospectus.

With respect to the Reorganization, if shareholders of the Target Fund approve the Agreement and other closing conditions are satisfied, the assets of the Target Fund will be delivered to the Acquiring Fund’s custodian for the account of the Acquiring Fund in exchange for the assumption by the Acquiring Fund of liabilities of the Target Fund and delivery by the Acquiring Fund to the holders of record as of the Effective Time (as defined below) of the issued and outstanding shares of the Target Fund of a number of shares of the Acquiring Fund (including, if applicable, fractional shares rounded to the nearest thousandth), having an aggregate net asset value equal to the value of the net assets of the Target Fund so transferred, all determined and adjusted as provided in the Agreement. The value of your account with the Acquiring Fund immediately after the Reorganization will be the same as the value of your account with the Target Fund immediately prior to the Reorganization.

The class or classes of Acquiring Fund shares that shareholders will receive in connection with the Reorganization will depend on the class or classes of Target Fund shares that shareholders hold as described above under “Comparison of Share Classes and Distribution Arrangements.”

The Target Fund and Acquiring Fund have made representations and warranties in the form of Agreement that are customary in matters such as the Reorganization.

If shareholders approve the Reorganization and if all of the closing conditions set forth in the Agreement are satisfied or waived, consummation of the Reorganization (the “Closing”) is expected to occur on or about May 2, 2011, (the “Closing Date”) immediately prior to the opening of regular trading on the New York Stock Exchange on the Closing Date (the “Effective Time”). Following receipt of the requisite shareholder vote in favor of the Reorganization and as soon as reasonably practicable after the Closing, the outstanding shares of the Target Fund will be terminated in accordance with its governing documents and applicable law.

The Agreement may be terminated and the Reorganization may be abandoned at any time by mutual agreement of the parties. The Agreement may be amended or modified in a writing signed by the parties to the Agreement.

Board Considerations in Approving the Reorganization

As discussed above, on June 1, 2010, Invesco acquired the retail mutual fund business of Morgan Stanley, which included 92 Morgan Stanley and Van Kampen branded funds. This transaction filled gaps in Invesco’s product line-up and has enabled Invesco to expand its investment offerings to retail customers. The transaction also resulted in significant product overlap. The Reorganization proposed in this Joint Proxy Statement/Prospectus are part of a larger group of reorganizations across Invesco’s mutual fund platform. The reorganizations are designed to put forth Invesco’s most compelling investment processes and strategies, reduce product overlap and create scale in the resulting funds.

Because of the large number of proposed reorganizations, each Board of Trustees of the Invesco Funds created an ad hoc committee comprised of both Invesco Fund trustees and Van Kampen legacy trustees (the “Ad Hoc Merger Committees”). The Ad Hoc Merger Committee of the Board met separately three times, from September 2, 2010 through October 13, 2010 to discuss the proposed Reorganizations. Two separate meetings of the full Board were also held to review and consider the Reorganizations, including presentations by the Ad Hoc Merger Committee. The trustees who are not “interested persons,” as that term is defined in the 1940 Act, of the Trust (the “Independent Trustees”) held a separate meeting prior to the meeting of the full Board to consider these matters. The Independent Trustees have been advised on this matter by independent counsel to the Independent Trustees and by the independent Senior Officer, an officer of the Trust who reports directly to the Independent Trustees. The Board requested and received from Invesco Advisers and IDI written materials containing relevant information about the Funds and the proposed Reorganizations, including fee and expense information on an actual and pro forma estimated basis, and comparative portfolio composition and performance data.

The Board considered the potential benefits and costs of the Reorganization to the Target Fund, the Acquiring Fund and their respective shareholders. The Board reviewed detailed information comparing the following information for the Target Fund and the Acquiring Fund: (1) investment objectives, policies and restrictions; (2) portfolio management; (3) portfolio composition; (4) the comparative short-term and long-term investment performance; (5) the current expense ratios and expense structures, including contractual investment advisory fees; (6) the expected federal income tax consequences to the Funds, including any impact on capital loss carry forwards; and (7) relative asset size and net purchase (redemption) trends. The Board also considered the benefits to the Target Fund of (i) combining with a similar Fund to create a larger fund with a more diversified shareholder base that may also achieve certain economies of scale as certain fixed expenses are allocated over a larger asset base, and (ii) Invesco Advisers or one of its affiliates’ paying a portion of the expenses related to the reorganizations for those funds that are currently subject to expense caps; (iii) Invesco Advisers’ agreement for certain acquiring funds to cap expenses for two years after the Closing; and (iv) the expected tax-free nature of the reorganizations for each target fund and its shareholders for federal income tax purposes. The Board also considered the overall goal of the reorganizations to rationalize the Invesco Funds to enable IDI to better focus on the combined funds to promote additional asset growth.

With respect to the proposed Reorganization of the Target Fund into the Acquiring Fund, the Board further considered that (i) the advisory fee of the Acquiring Fund is higher than the advisory fee of the Target Fund; and (ii) Invesco Advisers’ agreement to limit the Acquiring Fund’s total expenses for two years so that expenses, after fee waivers, do not exceed those of the Target Funds as set forth in the fee tables above.

Fund could potentially benefit from the growth in assets realized by the Reorganization, with the potential to achieve certain economies of scale. The Board concluded that the Reorganization is in the best interests of the Target Fund and the Acquiring Fund and that no dilution of value would result to the shareholders of the Target Fund or the Acquiring Fund from the Reorganization. Consequently, the Board approved the Agreement and the Reorganization on October 27, 2010.

Federal Income Tax Considerations

The following is a general summary of the material U.S. federal income tax considerations of the Reorganization and is based upon the current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), the existing U.S. Treasury Regulations thereunder, current administrative rulings of the IRS and published judicial decisions, all of which are subject to change. These considerations are general in nature and individual shareholders should consult their own tax advisors as to the federal, state, local, and foreign tax considerations applicable to them and their individual circumstances. These same considerations generally do not apply to shareholders who hold their shares in a tax-deferred account.

The Reorganization is intended to be a tax-free reorganization pursuant to Section 368(a) of the Code. The principal federal income tax considerations that are expected to result from the Reorganization of the Target Fund into the Acquiring Fund are as follows:

	•		no gain or loss will be recognized by the Target Fund or the shareholders of the Target Fund as a result of the Reorganization;

	•		no gain or loss will be recognized by the Acquiring Fund as a result of the Reorganization;

	•		the aggregate tax basis of the shares of the Acquiring Fund to be received by a shareholder of the Target Fund will be the same as the shareholder’s aggregate tax basis of the shares of the Target Fund; and

	•		the holding period of the shares of the Acquiring Fund received by a shareholder of the Target Fund will include the period that a shareholder held the shares of the Target Fund (provided that such shares of the Target Fund are capital assets in the hands of such shareholder as of the Closing).

Neither the Target Fund nor the Acquiring Fund have requested or will request an advance ruling from the IRS as to the federal tax consequences of the Reorganization. As a condition to Closing, Stradley Ronon Stevens & Young, LLP will render a favorable opinion to the Target Fund and the Acquiring Fund as to the foregoing federal income tax consequences of the Reorganization, which opinion will be conditioned upon, among other things, the accuracy, as of the Effective Time, of certain representations of the Target Fund and the Acquiring Fund upon which Stradley Ronon Stevens & Young, LLP will rely in rendering its opinion. A copy of the opinion will be filed with the Securities and Exchange Commission and will be available for public inspection. See “Where to Find Additional Information.”

Opinions of counsel are not binding upon the IRS or the courts. If the Reorganization is consummated but the IRS or the courts determine that the Reorganization does not qualify as a tax-free reorganization under the Code, and thus is taxable, the Target Fund would recognize gain or loss on the transfer of its assets to the Acquiring Fund and each shareholder of the Target Fund would recognize a taxable gain or loss equal to the difference between its tax basis in its Target Fund shares and the fair market value of the shares of the Acquiring Fund it receives.

Prior to the Closing of the Reorganization, the Target Fund will distribute, and the Acquiring Fund may distribute, to their respective shareholders any undistributed income and gains (net of available capital loss carryovers) to the extent required to avoid entity level tax or as otherwise deemed desirable. Such distributions, if made, are anticipated to be made in the 2011 calendar year and would be taxable to shareholders in such year.

a portion of a Fund’s capital loss carryovers may become unavailable the effect of which may be to accelerate the recognition of taxable gain to the combined Fund and its shareholders post-Closing. First, the capital loss carryovers of the Target Fund, increased by any current year loss or decreased by any current year gain, together with any net unrealized depreciation in the value of its portfolio investments (collectively, its “aggregate capital loss carryovers”), are expected to become subject to an annual limitation. Losses in excess of that limitation may be carried forward to succeeding tax years, subject to an overall eight-year carryover period. The annual limitation will generally equal the net asset value of the Target Fund on the Closing Date multiplied by the “long-term tax-exempt rate” published by the IRS. If the Target Fund has net unrealized built-in gains at the time of Closing the Reorganization (i.e., unrealized appreciation in value of the Fund’s investments), the annual limitation for a taxable year will be increased by the amount of such built-in gains that are recognized in the taxable year. Second, if a Fund has built-in gains at the time of the Reorganization that are realized by the combined Fund in the five-year period following the Reorganization, such built-in gains, when realized, may not be offset by the losses (including any capital loss carryovers and “built in losses”) of the other Fund. Third, the capital losses of the Target Fund that may be used by the Acquiring Fund (including to offset any “built-in gains” of the Target Fund itself) for the first taxable year ending after the Closing Date will be limited to an amount equal to the capital gain net income of the Acquiring Fund for such taxable year (excluding capital loss carryovers) treated as realized post-Closing based on the number of days remaining in such year. Fourth, the Reorganization may result in an earlier expiration of a Fund’s capital loss carryovers because the Reorganization causes the Target Fund’s tax year to close early in the year of the Reorganization. The aggregate capital loss carryovers of the Funds and the approximate annual limitation on the use by the Acquiring Fund, post-Closing, of the Target Fund’s aggregate capital loss carryovers following the Reorganization are as follows:


	Target Fund			Acquiring Fund
	(000,000s)			(000,000s)
	at 2/28/2010			at 2/28/2010
Aggregate capital loss carryovers on a tax basis (1)		($271.6	)		($142.5	)
Unrealized Net Appreciation (Depreciation) in Investments on a Tax Basis	$	4.7		$	3.8
Aggregate Net Asset Value	$	585.2		$	836.5
Approximate annual limitation (2)	$	23.3			N/A


(1)		Includes realized gain, to the extent not offset by expiring capital loss carryovers, or loss for the current fiscal year determined on the basis of generally accepted accounting principles; excludes any excess capital loss carryovers that are anticipated to expire on or prior to Closing.

(2)		Based on the long-term tax-exempt rate for ownership changes during October 2010 of 3.98%.

The annual limitation on the use of the Target Fund’s aggregate capital loss carryovers will likely limit the use of such losses by the Acquiring Fund, post-Closing, to offset capital gains, if any, it realizes. The aggregate capital loss carryovers of the Acquiring Fund may continue to be available, provided the Acquiring Fund is the larger of the two Funds on the Closing Date. In general, the ability of a fixed income fund to utilize capital loss carryovers is limited because fixed income securities do not generally generate significant capital gains. The ability of the Acquiring Fund to absorb its own capital loss carryovers and those of the Target Fund post-Closing depends upon a variety of factors that can not be known in advance. For more information with respect to each Fund’s capital loss carryovers, please refer to the Fund’s shareholder report.

In addition, if the Acquiring Fund following the Reorganization has proportionately greater unrealized appreciation in its portfolio investments as a percentage of its net asset value than the Target Fund, shareholders of the Target Fund, post-Closing, may receive greater amounts of taxable gain as such portfolio investments are sold than they otherwise might have if the Reorganization had not occurred. The Target Fund’s unrealized appreciation (depreciation) in value of investments on a tax basis as a percentage of its net asset value at February 28, 2010 is 1%, compared to the Acquiring Fund at February 28, 2010 of 0%, and on a combined basis of 1%.

After the Reorganization, shareholders will continue to be responsible for tracking the adjusted tax basis and holding period of their shares for federal income tax purposes.

Costs of the Reorganization

The total cost of the Reorganization to be paid by the Acquiring Fund is estimated to be $30,000. The estimated total cost of the Reorganization for the Target Fund, as well as the estimated proxy solicitation costs for the Target Fund, which are a part of the total Reorganization costs, are set forth in the table below.

Where the Target Fund is not paying Reorganization costs, Invesco Advisers will bear these costs. The costs of a Reorganization include legal counsel fees, independent accountant fees, expenses related to the printing and mailing of this Joint Proxy Statement/Prospectus and fees associated with the proxy solicitation but do not include any portfolio transaction costs arising from a Reorganization.

VOTING INFORMATION

Proxy Statement/Prospectus

We are sending you this Proxy Statement/Prospectus and the enclosed proxy card because the Board is soliciting your proxy to vote at the Meeting and at any adjournments of the Meeting. This Proxy Statement/Prospectus gives you information about the business to be conducted at the Meeting. Target Fund shareholders may vote by appearing in person at the Meeting and following the instructions below. You do not need to attend the Meeting to vote, however. Instead, you may simply complete, sign and return the enclosed proxy card or vote by telephone or through a website established for that purpose.

This Proxy Statement/Prospectus, the enclosed Notice of Meeting of Shareholders and the enclosed proxy card are expected to be mailed on or about January __, 2011 to all shareholders entitled to vote. Shareholders of record of the Target Fund as of the close of business on January 14, 2011 (the “Record Date”) are entitled to vote at the Meeting. The number of outstanding shares of each class of the Target Fund on December 15, 2010 can be found at Exhibit A. Each share is entitled to one vote for each full share held, and a proportionate fractional vote for each fractional share held.

Proxies will have the authority to vote and act on behalf of shareholders at any adjournment of the Meeting. If a proxy is authorized to vote for a shareholder, the shareholder may revoke the authorization at any time before it is exercised by sending in another proxy card with a later date or by notifying the Secretary of the Target Fund in writing at the address of the Target Fund set forth on the cover page of the Proxy Statement/Prospectus before the Meeting that the shareholder has revoked its proxy. In addition, although merely attending the Meeting will not revoke your proxy, if a shareholder is present at the Meeting, the shareholder may withdraw the proxy and vote in

person. However, if your shares are held through a broker-dealer or other financial intermediary, you will need to obtain a “legal proxy” from them in order to vote your shares at the Meeting.

Quorum Requirement and Adjournment

A quorum of shareholders is necessary to hold a valid shareholder meeting of the Target Fund. For the Target Fund, a quorum will exist if shareholders representing one-third of the outstanding shares of the Target Fund entitled to vote are present at the Meeting in person or by proxy.

Proxies received prior to the Meeting on which no vote is indicated will be voted “FOR” the Agreement. Because the proposal described in this Proxy Statement/Prospectus is considered “non-routine,” under the rules applicable to broker-dealers, if your broker holds your shares in its name, the broker will not be entitled to vote your shares if it has not received instructions from you.

Abstentions will count as shares present at the Meeting for purposes of establishing a quorum. If a quorum is not present at the Meeting or if a quorum is present but sufficient votes to approve the Agreement are not received, the person(s) presiding over the Meeting or the persons named as proxies may propose one or more adjournments of the Meeting to allow for further solicitation of votes. The persons named as proxies will vote those proxies that they are entitled to vote in favor of such an adjournment, provided that they determine that such an adjournment and additional solicitation is reasonable and in the interest of shareholders based on a consideration of all relevant factors, including, among other things, the percentage of votes then cast, the percentage of negative votes then cast, the nature of the proposed solicitation activities and the nature of the reasons for such further solicitation.

Vote Necessary to Approve the Agreement

The Board has unanimously approved the Agreement, subject to shareholder approval. Shareholder approval of the Agreement requires the affirmative vote of the lesser of (i) 67% or more of the shares present at the Meeting, if the holders of more than 50% of the outstanding shares of the Target Fund are present in person or represented by proxy; or (ii) more than 50% of the outstanding shares of the Target Fund. Abstentions are counted as present but are not considered votes cast at the Meeting. Abstentions therefore will have the same effect as a vote against the Agreement because approval of the Agreement requires the affirmative vote of a percentage of either the shares present at the Meeting or the outstanding shares of the Target Fund.

Proxy Solicitation

The Target Fund has engaged the services of Computershare Fund Services, Inc. (“Solicitor”) to assist in the solicitation of proxies for the Meeting. Solicitor costs are described under the “Costs of the Reorganization” section of this Proxy Statement/Prospectus. Proxies are expected to be solicited principally by mail, but the Target Fund or Solicitor may also solicit proxies by telephone, facsimile or personal interview. The Target Fund’s officers may also solicit proxies but will not receive any additional or special compensation for any such solicitation.

Under the agreement with the Solicitor, the Solicitor will be paid a project management fee as well as telephone solicitation expenses incurred for reminder calls, outbound telephone voting, confirmation of telephone votes, inbound telephone contact, obtaining shareholders’ telephone numbers, and providing additional materials upon shareholder request. The agreement also provides that the Solicitor shall be indemnified against certain liabilities and expenses, including liabilities under the federal securities laws.

Other Meeting Matters

Management is not aware of any matters to be presented at the Meeting other than as is discussed in this Proxy Statement/Prospectus. Under the Target Fund’s bylaws, business transacted at a special meeting such as this Meeting shall be limited to (i) the purpose stated in the notice; and (ii) adjournment of the special meeting with regard to the stated purpose. If any other matters properly come before the Meeting, the shares represented by proxies will be voted with respect thereto in accordance with their best judgment.

Share Ownership by Large Shareholders, Management and Trustees

A list of the name, address and percent ownership of each person who, as of December 15, 2010, to the knowledge of the Target Fund and Acquiring Fund, owned 5% or more of the outstanding shares of a class of such Target Fund or Acquiring Fund, respectively, can be found at Exhibits B and C.

Information regarding the ownership of shares of the Target Fund and the Acquiring Fund by the Trustees and executive officers of the Trusts can be found at Exhibit B and Exhibit C.

OTHER MATTERS

Capitalization

The following table sets forth as of September 30, 2010, for the Reorganization, the total net assets, number of shares outstanding and net asset value per share of each class of each Fund. This information is generally referred to as the “capitalization” of a Fund. The term “pro forma capitalization” means the expected capitalization of the Acquiring Fund after it has combined with the Target Fund. The pro forma capitalization column in the table assumes that the Reorganization has taken place. The capitalizations of the Target Fund, the Acquiring Fund and their classes are likely to be different on the Closing Date as a result of daily share purchase, redemption, and market activity.


					*Pro Forma*			*Acquiring Fund (pro***
	Target		Acquiring Fund		Adjustments			*forma*)
Net assets (all classes)	$	509,070,854	$	898,428,010	$	—		$	1,407,498,864

Institutional Class net asset value per share	$	9.62	$	4.21				$	4.21


1.		Invesco will bear 100% of the Reorganization expenses of the Target Fund. As a result, there are no pro forma adjustments to net assets.

2.		Shares Outstanding have been adjusted for the accumulated change in the number of shares of the Target Funds shareholder accounts based on the relative value of the Target Funds’ and the Acquiring Funds Net Asset Value Per Share assuming the Reorganization would have taken place on September 30, 2010.

Dissenters’ Rights

If the Reorganization is approved at the Meeting, Target Fund shareholders will not have the right to dissent and obtain payment of the fair value of their shares because the exercise of dissenters’ rights is subject to the forward pricing requirements of Rule 22c-1 under the 1940 Act, which supersedes state law. Shareholders of the Target Fund do, however, have the right to redeem their shares at net asset value subject to applicable deferred sales charges and/or redemption fees (if any) until the closing date of the Reorganization. After the Reorganization, Target Fund shareholders will hold shares of the Acquiring Fund, which may also be redeemed at net asset value subject to applicable deferred sales charges and/or redemption fees (if any).

Shareholder Proposals

The Funds do not generally hold annual meetings of shareholders. A shareholder desiring to submit a proposal intended to be presented at any meeting of shareholders of a Target Fund hereafter called should send the proposal to the Target Fund at the Target Fund’s principal offices so that it is received within a reasonable time before the proxy materials are printed and mailed. If the proposed Reorganization is approved and completed for the Target Fund, shareholders of the Target Fund will become shareholders of the Acquiring Fund and, thereafter, will be subject to the notice requirements of the Acquiring Fund. The mere submission of a proposal by a shareholder does not guarantee that such proposal will be included in a proxy statement because compliance with certain rules under the federal securities laws is required before inclusion of the proposal is required. Also, the submission does not mean that the proposal will be presented at a future meeting. For a shareholder proposal to be considered at a future shareholder meeting, it must be a proper matter for consideration under applicable law.

Exhibit D

AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF REORGANIZATION (“Agreement”) is adopted as of this ___ day of __________, 2010 by and among (i) each of the Invesco open-end registered investment companies identified as a Target Entity on Exhibit A hereto (each a “Target Entity”) separately, on behalf of its respective series identified on Exhibit A hereto (each a “Target Fund”); (ii) each of the Invesco open-end registered investment companies identified as an Acquiring Entity on Exhibit A hereto (each an “Acquiring Entity”), separately on behalf of its respective series identified on Exhibit A hereto (each an “Acquiring Fund”); and (iii) Invesco Advisers, Inc. (“IAI”).

WHEREAS, the parties hereto intend for each Acquiring Fund and its corresponding Target Fund (as set forth in Exhibit A hereto) to enter into a transaction pursuant to which: (i) the Acquiring Fund will acquire the assets and assume the liabilities of the Target Fund in exchange for the corresponding class or classes of shares (as applicable) of the Acquiring Fund identified on Exhibit A of equal value to the net assets of the Target Fund being acquired, and (ii) the Target Fund will distribute such shares of the Acquiring Fund to shareholders of the corresponding class of the Target Fund, in connection with the liquidation of the Target Fund, all upon the terms and conditions hereinafter set forth in this Agreement (each such transaction, a “Reorganization” and collectively, the “Reorganizations”);

WHEREAS, each Target Entity and each Acquiring Entity is an open-end, registered investment company of the management type; and

WHEREAS, this Agreement is intended to be and is adopted as a plan of reorganization and liquidation with respect to each Reorganization within the meaning of Section 368(a)(1) of the United States Internal Revenue Code of 1986, as amended (the “Code”).

NOW, THEREFORE, in consideration of the premises and of the covenants and agreements hereinafter set forth, and intending to be legally bound, the parties hereto covenant and agree as follows:

DESCRIPTION OF THE REORGANIZATIONS

1.1. It is the intention of the parties hereto that each Reorganization described herein shall be conducted separately from the others, and a party that is not a party to a Reorganization shall incur no obligations, duties or liabilities with respect to such Reorganization by reason of being a party to this Agreement. If any one or more Reorganizations should fail to be consummated, such failure shall not affect the other Reorganizations in any way.

1.2. Provided that all conditions precedent to a Reorganization set forth herein have been satisfied as of the Closing Date (as defined in Section 3.1), and based on the representations and warranties each party provides to the others, each Target Entity and its corresponding Acquiring Entity agree to take the following steps with respect to their Reorganization(s), the parties to which and classes of shares to be issued in connection with which are set forth in Exhibit A:

(a) The Target Fund shall transfer all of its Assets, as defined and set forth in Section 1.2(b), to the Acquiring Fund, and the Acquiring Fund in exchange therefor shall assume the Liabilities, as defined and set forth in Section 1.2(c), and deliver to the Target Fund the number of full and fractional Acquiring Fund shares determined in the manner set forth in Section 2.

(b) The assets of the Target Fund to be transferred to the Acquiring Fund shall consist of all assets and property, including, without limitation, all cash, securities, commodities and futures interests, claims (whether absolute or contingent, known or unknown, accrued or unaccrued and including, without limitation, any interest in pending or future legal claims in connection with past or present portfolio holdings, whether in the form of class action claims, opt-out or other direct litigation claims, or regulator or government-established investor recovery fund claims, and any and all resulting recoveries) and dividends or interest receivable that are owned by the Target Fund and any deferred or prepaid expenses shown as an asset on the books of the Target Fund on the Closing Date, except for cash, bank deposits or cash equivalent securities in an amount necessary to pay the estimated costs of extinguishing any Excluded Liabilities (as defined in Section 1.2(c)) and cash in an amount necessary to pay any distributions pursuant to Section 7.1(g) (collectively, “Assets”).

(c) The Acquiring Fund shall assume all of the liabilities of the Target Fund, whether accrued or contingent, known or unknown, existing at the Closing Date, except for the Target Fund’s Excluded Liabilities (as defined below), if any, pursuant to this Agreement (collectively, with respect to each Target Fund separately, “Liabilities”). If prior to the Closing Date the Acquiring Entity identifies a liability that the Acquiring Entity and the Target Entity mutually agree should not be assumed by the Acquiring Fund, such liability shall be excluded from the definition of Liabilities hereunder and shall be listed on a Schedule of Excluded Liabilities to be signed by the Acquiring Entity and the Target Entity at Closing and attached to this Agreement as Schedule 1.2(c) (the “Excluded Liabilities”). The Assets minus the Liabilities of a Target Fund shall be referred to herein as the Target Fund’s “Net Assets.”

(d) As soon as is reasonably practicable after the Closing, the Target Fund will distribute to its shareholders of record (“Target Fund Shareholders”) the shares of the Acquiring Fund of the corresponding class received by the Target Fund pursuant to Section 1.2(a), as set forth in Exhibit A, on a pro rata basis within that class, and the Target Fund will as promptly as practicable completely liquidate and dissolve. Such distribution and liquidation will be accomplished, with respect to each class of the Target Fund’s shares, by the transfer of the Acquiring Fund shares of the corresponding class then credited to the account of the Target Fund on the books of the Acquiring Fund to open accounts on the share records of the Acquiring Fund in the names of the Target Fund Shareholders of the class. The aggregate net asset value of the Acquiring Fund shares to be so credited to the corresponding Target Fund Shareholders shall be equal to the aggregate net asset value of the corresponding Target Fund’s shares owned by the Target Fund Shareholders on the Valuation Date. The Acquiring Fund shall not issue certificates representing shares in connection with such exchange.

-2-

(e) Ownership of Acquiring Fund shares will be shown on its books, as such are maintained by the Acquiring Fund’s transfer agent.

VALUATION

2.1. With respect to each Reorganization:

(a) The value of the Target Fund’s Assets shall be the value of such Assets computed as of immediately after the close of regular trading on the New York Stock Exchange (“NYSE”), which shall reflect the declaration of any dividends, on the business day next preceding the Closing Date (the “Valuation Date”), using the Target Fund’s valuation procedures established by the Target Entity’s Board of Trustees.

(b) The net asset value per share of each class of the Acquiring Fund shares issued in connection with the Reorganization shall be the net asset value per share of the corresponding class of each class computed on the Valuation Date using the Acquiring Fund’s valuation procedures established by the Acquiring Entity’s Board of Trustees, which are the same as the Target Fund’s valuation procedures.

(c) The number of shares issued of each class of the Acquiring Fund (including fractional shares, if any, rounded to the nearest thousandth) in exchange for the Target Fund’s Net Assets shall be determined by dividing the value of the Net Assets of the Target Fund attributable to each class of Target Fund shares by the net asset value per share of the corresponding share class of the Acquiring Fund.

(d) All computations of value shall be made by the Target Fund’s and the Acquiring Fund’s designated recordkeeping agent using the valuation procedures described in this Section 2.

CLOSING AND CLOSING DATE

3.1. Each Reorganization shall close on the date identified on Exhibit A or such other date as the parties may agree with respect to any or all Reorganizations (the “Closing Date”). All acts taking place at the closing of a Reorganization (the “Closing”) shall be deemed to take place simultaneously as of immediately prior to the opening of regular trading on the NYSE on the Closing Date of that Reorganization unless otherwise agreed to by the parties (the “Closing Time”).

3.2. With respect to each Reorganization:

(a) The Target Fund’s portfolio securities, investments or other assets that are represented by a certificate or other written instrument shall be transferred and delivered by the Target Fund as of the Closing Date to the Acquiring Fund’s Custodian for the account of the Acquiring Fund, duly endorsed in proper form for transfer and in such condition as to constitute good delivery thereof. The Target Fund shall direct the Target Fund’s custodian (the “Target Custodian”) to deliver to the Acquiring Fund’s Custodian as of the Closing Date by book entry, in accordance with the customary practices of Target Custodian and any securities depository (as defined in Rule 17f-4 under the

-3-

Investment Company Act of 1940, as amended (the “1940 Act”)), in which the Assets are deposited, the Target Fund’s portfolio securities and instruments so held. The cash to be transferred by a Target Fund shall be delivered to the Acquiring Fund’s Custodian by wire transfer of federal funds or other appropriate means on the Closing Date.

(b) The Target Entity shall direct the Target Custodian for each Target Fund to deliver, at the Closing, a certificate of an authorized officer stating that (i) except as permitted by Section 3.2(a), the Assets have been delivered in proper form to the Acquiring Fund no later than the Closing Time on the Closing Date, and (ii) all necessary taxes in connection with the delivery of the Assets, including all applicable Federal, state and foreign stock transfer stamps, if any, have been paid or provision for payment has been made.

(c) At such time prior to the Closing Date as the parties mutually agree, the Target Fund shall provide (i) instructions and related information to the Acquiring Fund or its transfer agent with respect to the Target Fund Shareholders, including names, addresses, dividend reinvestment elections and tax withholding status of the Target Fund Shareholders as of the date agreed upon (such information to be updated as of the Closing Date, as necessary) and (ii) the information and documentation maintained by the Target Fund or its agents relating to the identification and verification of the Target Fund Shareholders under the USA PATRIOT ACT and other applicable anti-money laundering laws, rules and regulations and such other information as the Acquiring Fund may reasonably request. The Acquiring Fund and its transfer agent shall have no obligation to inquire as to the validity, propriety or correctness of any such instruction, information or documentation, but shall, in each case, assume that such instruction, information or documentation is valid, proper, correct and complete.

(d) The Target Entity shall direct each applicable transfer agent for a Target Fund (the “Target Transfer Agent”) to deliver to the Acquiring Fund at the Closing a certificate of an authorized officer stating that its records, as provided to the Acquiring Entity, contain the names and addresses of the Target Fund Shareholders and the number of outstanding shares of each class owned by each such shareholder immediately prior to the Closing.

PROPOSAL: TO APPROVE AN AGREEMENT AND PLAN OF REORGANIZATION

SUMMARY OF KEY INFORMATION

On what am I being asked to vote?

As a shareholder of the Target Fund, you are being asked to consider and vote to approve the Agreement under which the assets and liabilities of the Target Fund you own will be transferred to the Acquiring Fund. (A table showing the Target Fund share classes and the corresponding Acquiring Fund share classes is included in the section entitled “ADDITIONAL INFORMATION ABOUT THE FUNDS — Comparison of Share Classes and Distribution Arrangements” of this Proxy Statement/Prospectus).

Has my Fund’s Board of Trustees approved the Reorganization?

What are the reasons for the proposed Reorganization?

In considering the Reorganization and Agreement, the Board considered these and other factors in concluding that the Reorganization would be in the best interest of the Funds. The Board’s considerations are described in more detail in the section below titled “THE PROPOSED REORGANIZATION — Board Considerations in Approving the Reorganization” section below.

What effect will the Reorganization have on me as a shareholder?

How do the Funds’ investment objectives, principal investment strategies and risks compare?

Investment Objectives


Target Fund		Acquiring Fund
The Fund’s investment objective is total return, comprised of current income and capital appreciation.		The Fund’s primary investment objective is to seek to provide current income with preservation of capital. Capital appreciation is a secondary objective that is sought only when consistent with the Fund’s primary investment objective.

How do the Funds’ expenses compare?

*		Expense ratios reflect annual fund operating expenses for the most recent fiscal year (as disclosed in the Funds’ current prospectuses) of the Target Fund (February 28, 2010) and the Acquiring Fund (August 31, 2010). Pro forma numbers are estimated as if the Reorganization had been completed as of September 1, 2009 and do not include the estimated costs of the Reorganization to be borne by the Acquiring Fund. The estimated Reorganization costs that the Target Fund will bear are $200,000. Invesco Advisers estimates that shareholders will recoup these costs through reduced expenses in 4 months or less. For more information on the costs of the Reorganization to be borne by the Funds, see “Costs of the Reorganization” below.

1.		Based on estimated amounts for the current fiscal year.

2.		Investor Class shareholders will be issued Class A shares as part of the Reorganization.

3.		Effective upon the closing of the Reorganization, the Acquiring Fund’s distributor has agreed, through at least June 30, 2012, to waive 12b-1 fees for Class B and Class C shares to the extent necessary to limit 12b-1 fees to 0.59% and 0.95%, respectively of the Acquiring Fund’s average daily net assets. Unless the Board and Invesco Advisers mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2012.

The Example is not a representation of past or future expenses. Each Fund’s actual expenses, and an investor’s direct and indirect expenses, may be more or less than those shown. The table and the assumption in the Example of a 5% annual return are required by regulations of the SEC applicable to all mutual funds. The 5% annual return is not a prediction of and does not represent the Target Fund’s or Acquiring Fund’s projected or actual performance.

How do the performance records of the Funds compare?

The performance history of each Fund for certain periods as of September 30, 2010 is shown below. The returns below may not be indicative of a Fund’s future performance. The table below compares the performance history of the Acquiring Fund’s oldest share class to the performance history of the comparable class of the Target Fund as of September 30, 2010. Other classes of shares that are not presented would have had substantially similar annual returns because the shares are invested in the same portfolio of securities and the annual returns will differ only to the extent that the classes do not have the same expenses. The prospectuses for the Funds contain additional performance information under the headings “Performance Information” and “Financial Highlights.” Additional performance information and a discussion of performance are also included in each Fund’s most recent annual report to shareholders.

^1.		The above total return figures reflect the maximum front-end sales charge (load) of 4.75% applicable to Class A shares.

^2.		The returns shown for periods prior to June 1, 2010 are those of the Class A shares of a predecessor fund that was advised by Van Kampen Asset Management and was reorganized into the Acquiring Fund on June 1, 2010. The returns shown for periods after June 1, 2010 are those of the Acquiring Fund. The returns of the Acquiring Fund are different from the predecessor fund as they had different expenses and sales charges.

How do the management, investment manager and other service providers of the Funds compare?

Each Fund is overseen by the same Board and officers. In addition, Invesco Advisers, a registered investment adviser, serves as primary investment adviser for each Fund pursuant to an investment advisory agreement that contains substantially identical terms (except for fees) for each Fund. The effective investment advisory fee for the Acquiring Fund is lower than the effective investment advisory fee of the Target Fund at current asset levels but may be higher at higher asset levels. See the section of this Proxy Statement/Prospectus entitled “SUMMARY OF KEY INFORMATION — How do the Funds’ expenses compare?” for more information about fees. Invesco Advisers is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. Invesco Advisers has acted as an investment adviser since its organization in 1976. As of September 30, 2010, Invesco Advisers had $300.3 billion under management. Invesco Advisers is an indirect, wholly owned subsidiary of Invesco.

How do the Funds’ purchase and redemption procedures, distribution policies and exchange policies compare?

The sales charges, sales charge exemptions, distribution and servicing arrangements, purchase and redemption procedures and exchange policies are generally similar. However, as part of the Reorganization, Investor Class shareholders of the Target Fund will receive Class A shares of the Acquiring Fund. Class A shares have a

different sales load structure and distribution and shareholder servicing arrangements. For more information see the section entitled “Comparison of Share Classes and Distribution Arrangements.”

Will the Acquiring Fund have different portfolio managers than the Target Fund?

Yes. The portfolio management team of the Target Fund and the Acquiring Fund are similar but the Target Fund includes two portfolio managers who are not members of the portfolio management team of the Acquiring Fund. The Acquiring Fund prospectus that accompanies this Proxy Statement/Prospectus provides biographical information about the key individuals that comprise the portfolio management team for the Acquiring Fund.

Will there be any tax consequences resulting from the proposal?

When is the Reorganization expected to occur?

If shareholders of the Target Fund approve the Reorganization, it is anticipated that such Reorganization will occur on or about May 2, 2011.

How do I vote on the Reorganization?

There are several ways you can vote your shares, including in person at the Meeting, by mail, by telephone or via the Internet. The proxy card that accompanies this Proxy Statement/Prospectus provides detailed instructions on how you may vote your shares. If you properly fill in and sign your proxy card and send it to us in time to vote at the Meeting, your “proxy” (the individuals named on your proxy card) will vote your shares as you have directed. If you sign your proxy card but do not make specific choices, your proxy will vote your shares FOR the proposal, as recommended by the Board, and in their best judgment on other matters.

What will happen if shareholders of a Target Fund do not approve the Reorganization?

If the shareholders of the Target Fund do not approve the Reorganization, the Target Fund’s Board will consider other possible courses of action for the Target Fund.

What if I do not wish to participate in the Reorganization?

Why are you sending me the Proxy Statement/Prospectus?

Where can I find more information about the Funds and the Reorganization?

ADDITIONAL INFORMATION ABOUT THE FUNDS

Comparison of Principal Investment Strategies

Investment Strategies. The investment strategies of the Acquiring Fund and the Target Fund are similar. The Acquiring Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for investment purposes) in corporate debt securities with original maturities of more than one year. The Target Fund invests primarily in fixed-rate U.S. dollar denominated corporate bonds. In attempting to meet its investment objective, the Target Fund may engage in active and frequent trading of portfolio securities.

In selecting securities for investment for the Acquiring Fund, the Adviser seeks to identify securities which entail reasonable credit risk considered in relation to the Fund’s investment policies, and emphasizes issuers it believes will remain financially sound and perform well in a range of market conditions. The Acquiring Fund may invest up to 20% of its total assets in convertible securities and up to 10% of its total assets in preferred stocks. The Target Fund may also invest in domestic and foreign government obligations, mortgage-backed and asset-backed securities, money market securities and convertible corporate debt.

A portion or all of the Acquiring Fund’s total assets may be invested in securities issued by foreign governments or corporations; provided, however, that the Fund may not invest more than 30% of its total assets in non-U.S. dollar denominated securities. The Target Fund may invest up to 40% of its total assets in foreign securities including bonds and other fixed income securities issued by issuers outside the U.S. The Target Fund may invest up to 10% of its total assets in non-U.S. dollar denominated securities. The Target Fund may also invest in bonds and other fixed income securities, whether or not considered foreign securities, which carry foreign credit exposure. The Target Fund may also invest up to 15% of its total assets in bonds and other fixed income securities of issuers located in developing markets.

The Acquiring Fund may purchase and sell options, futures contracts, options on futures contracts, swaps and structured products, which are derivative instruments, for various portfolio management purposes and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index. The Target Fund may also invest a significant portion of its assets in derivative instruments, such as options, futures (including currency futures), forward currency contracts, and swap agreements (including interest rate, currency, total return and credit default swaps.) The Target Fund may engage in these transactions for hedging or non-hedging purposes. The Target Fund utilizes active duration and yield curve positioning for risk management and for generating alpha versus its benchmark. Duration is a measure of volatility expressed in years and represents the anticipated percent change in a bond’s price at a single point in time for a 1% change in yield. As duration increases, volatility increases as applicable interest rates change.

Under normal market conditions, between 60% to 100% of the Acquiring Fund’s total assets are invested in investment grade securities, which are securities rated Baa or higher by Moody’s Investors Service, Inc. (“Moody’s”) or BBB or higher by Standard & Poor’s (“S&P”) at the time they are purchased, securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, commercial paper rated Prime by Moody’s or A by S&P and cash and cash equivalents. Up to 40% of the Acquiring Fund’s total assets may be invested in

securities rated Ba by Moody’s or BB by S&P at the time of purchase. No more than 20% of the Acquiring Fund’s total assets may be invested in securities rated B or lower by Moody’s or S&P, or which are unrated, although it is the Fund’s current policy not to buy any securities rated below B or unrated securities judged by the Adviser to be of comparable quality. Securities rated Ba or lower by Moody’s or BB or lower by S&P or unrated securities of comparable quality are commonly referred to as “junk bonds” and involve greater risks than investments in higher-grade securities. The Target Fund may invest up to 35% of its total assets in non-investment grade debt securities (“junk bonds”) and unrated debt securities deemed by the portfolio managers to be of comparable credit quality standards, but currently does not intend to invest more than 10% of its total assets in such securities.

Comparison of Principal Risks of Investing in the Funds


Principal Risk		Funds Subject to Risk
Active Trading Risk. The Fund may engage in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability.		Target Fund

Credit Risk. Credit risk refers to an issuer’s ability to make timely payments of interest and principal. To the extent that the Fund invests in securities with medium- or lower-credit qualities, it is subject to a higher level of credit risk than a fund that invests only in investment grade securities. Medium- and lower-grade securities (also sometimes known as junk bonds) may have less liquidity and a higher incidence of default than higher-grade securities. The Fund may incur higher expenses to protect the Fund’s interest in such securities. The credit risks and market prices of lower-grade securities, especially those with longer maturities or those that do not make regular interest payments, generally are more sensitive to negative issuer developments or adverse economic conditions and may be more volatile than are higher-grade securities.		Acquiring Fund Target Fund

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.		Acquiring Fund Target Fund

Risks of Using Derivative Instruments. Risks of derivatives include imperfect correlation between the value of the instruments and the underlying assets; risks of default by the other party to certain transactions; risks that the transactions may result in losses that partially or completely offset gains in portfolio positions; and risks that the transactions may not be liquid.		Acquiring Fund Target Fund

Market Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. Investments in debt securities generally are affected by changes in interest rates and the creditworthiness of the issuer. The prices of such securities tend to fall as interest rates rise, and such declines tend to be greater among debt securities with longer maturities. The value of a convertible security tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying security.		Acquiring Fund Target Fund

Developing Markets Securities Risk. Securities issued by foreign companies and governments located in developing countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.		Target Fund

Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in		Acquiring Fund Target Fund


Principal Risk		Funds Subject to Risk
financial reporting, differences in securities regulation and trading, and foreign taxation issues.

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.		Acquiring Fund Target Fund

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

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.		Acquiring Fund Target Fund

U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default.		Target Fund

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.		Acquiring Fund Target Fund

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.		Acquiring Fund Target Fund

Comparison of Fundamental and Non-Fundamental Investment Restrictions

Each Fund has adopted fundamental investment restrictions concerning, among other things, concentration in particular industries, borrowing and loaning money, and investing in real estate and commodities. In addition, as required by Rule 35d-1 under the 1940 Act, the Acquiring Fund has a non-fundamental investment restriction that requires the Fund to invest, under normal market conditions, at least 80% of its assets in corporate bonds at the time of investment. The Target Fund is not subject to Rule 35d-1 and does not have a similar provision as a non-fundamental investment restriction. Except for the Target Fund’s fundamental investment restriction relating to a minimum percentage of investment in a certain type of security, the fundamental and non-fundamental investment restrictions of the Target Fund and those of the Acquiring Fund are the same. Fundamental investment restrictions of a Fund cannot be changed without shareholder approval. Non-fundamental investment restrictions of a Fund can be changed by a Fund’s Board of Trustees.

Both the Target Fund and the Acquiring Fund may be subject to other investment restrictions that are not fully identified above. A full description of the Target Fund’s and the Acquiring Fund’s investment policies and restrictions may be found in their respective SAIs.

Comparison of Share Classes and Distribution Arrangements

The share classes offered by the Target Fund and the corresponding share classes of the Acquiring Fund that Target Fund shareholders will receive in connection with the Reorganization are as follows:


Target Fund Share Classes		Acquiring Fund Share Classes
Class A		Class A
Class B		Class B
Class C		Class C
Class Y		Class Y
Class R		Class R
Investor Class		Class A
Institutional Class		Institutional Class

Sales Charges. Class A shares of the Acquiring Fund can be purchased at the public offering price, which includes an initial sales charge ranging from 4.75% to zero, depending on the amount of your investment. The Acquiring Fund offers reductions and waivers of the initial sales charge on Class A shares to certain eligible investors or under certain circumstances, which are similar between the Funds. The prospectuses and statements of additional information of the Funds describe in detail these reductions and waivers. Target Fund shareholders who hold Investor Class shares will be reorganized into Class A shares of the Acquiring Fund.

You will not pay an initial sales charge on Acquiring Fund Class A shares that you receive in connection with the Reorganization. In addition, the exchange of Class A shares, Class B shares or Class C shares of the Target Fund for corresponding classes of the Acquiring Fund at the consummation of the Reorganization will not result in the imposition of any contingent deferred sales charge that applies to those share classes. Upon consummation of the Reorganization, former Target Fund shareholders of Class A shares, Class B shares or Class C shares will be credited for the period of time from their original date of purchase of the Target Fund Class A shares, Class B shares or Class C shares for purposes of determining the amount of any contingent deferred sales charge that may be due upon subsequent redemption, if any. In addition, the CDSC schedule that applies to the Class B shares of the Target Fund that you own will continue to apply to the Class B shares of the Acquiring Fund received in connection with the Reorganization. The Acquiring Fund initial sales charge for Class A shares and the contingent deferred sales charge that applies to Class A shares and Class C shares will apply to any Class A shares or Class C shares of the Acquiring Fund purchased after the Reorganization, unless you are eligible for a reduction or waiver of the initial sales charge or contingent deferred sales charge.

The sales charge schedule (if any) of the other share classes of the Target Fund are substantially the same as the sales charge schedule (if any) of the corresponding share classes of the Acquiring Fund. The Funds’ prospectuses describe the principal sales charges applicable to each such share class.

Distribution Fees. The Funds have adopted distribution plans and service plans (together, the “Distribution Plans”) pursuant to Rule 12b-1 under the Investment Company Act of 1940, as amended, (the “1940 Act”) with respect to each of their Class A, Class B, Class C, Class R, and Investor Class shares. Class Y and Institutional Class shares of the Funds are not subject to the Distribution Plans.

Pursuant to the Target Fund’s Distribution Plan, the Target Fund is authorized to make payments to Invesco Distributors, Inc., (“IDI”), the Fund’s principal underwriter in connection with the distribution of Target Fund shares and providing shareholder services at the annual rate of 0.25% of the Target Fund’s average daily net assets attributable to Class A shares, at the annual rate of 1.00% of the Target Fund’s average daily net assets attributable to Class B and Class C shares, and at the annual rate of 0.50% of the Target Fund’s average net assets attributable to Class R shares. Amounts received by IDI may be spent for activities or expenses primarily intended to result in the sale of shares or the servicing of shareholders.

The Target Fund is also authorized to make payments to IDI for activities or expenses primarily intended to result in the sale of Investor Class shares up to 0.25% of the Target Fund’s assets attributable to Investor Class shares. However, IDI may be reimbursed from the Target Fund only up to the amount it has spent on such activities

for Investor Class shares. This type of Distribution Plan is sometimes referred to as a “reimbursement-type” plan because the underwriter is only entitled to be reimbursed for its plan-related expenses.

The Distribution Plans for the Acquiring Fund and the Target Funds are similar, however, IDI may be reimbursed from an Acquiring Fund only up to the amount it has spent on activities or expenses primarily intended to result in the sale of shares or the servicing of shareholders, up to the same limits as the Target Funds’ Distribution Plans (i.e., 0.25% for Class A shares, 1.00% for Class B and Class C shares and 0.50% for Class R shares). Like the Distribution Plan for Investor Class shares of the Target Fund, this Distribution Plan is a “reimbursement-type” plan because IDI is only entitled to be reimbursed for its plan-related expenses.

The fee table under the “SUMMARY OF KEY INFORMATION — How do the Funds’ expenses compare” section of this Proxy Statement/Prospectus describes the fees paid under each Fund’s Distribution Plan for a recent period as well as an estimate of the fees to be paid under the Acquiring Fund’s Distribution Plan following the Reorganization.

Comparison of Purchase and Redemption Procedures

The purchase procedures employed by the Target Fund and the Acquiring Fund are substantially the same. Each Fund offers shares through its distributor on a continuous basis. Shares of the Funds may be purchased directly through the transfer agent and through other authorized financial intermediaries. Investors may purchase both initial and additional shares by mail, wire, telephone or the internet. The Acquiring Fund prospectus enclosed with this Proxy Statement/Prospectus describes in detail how shareholders can purchase Acquiring Fund shares. Class A, Class B (closed to new investments, except dividend reinvestments), Class C, Class Y and Investor Class shares of the Funds require a minimum investment of $1,000 ($250 for IRA, Roth IRA, and Coverdell Education Savings Accounts). Institutional Class shares of the Target Fund and the Acquiring Fund each require a minimum initial investment that ranges from $0 to $10 million, depending on the type of account making the investment. The Acquiring Fund’s prospectus describes the types of accounts to which the minimum initial investment applies. There is no minimum investment required to purchase Class R shares. For accounts participating in a systematic investment program, the minimum investment is $50 ($25 for IRA, Roth IRA, and Coverdell Education Savings Accounts). Certain exemptions apply as set forth in the Funds’ prospectuses. The foregoing investment minimums will not apply to shares received in connection with the Reorganization. However, investors may be charged a small-account fee if account balances remain below the required investment minimum for certain periods. See the Funds’ prospectuses for details.

Comparison of Distribution Policies

Each Fund declares and pays dividends of net investment income, if any, monthly, and capital gains distributions, if any, at least annually. Each Fund may also declare and pay capital gains distributions more than once per year as permitted by law. Each Fund automatically reinvests any dividends from net investment income or capital gains distributions, unless otherwise instructed by a shareholder to pay dividends and distributions in cash.

THE PROPOSED REORGANIZATION

Summary of Agreement and Plan of Reorganization

The class or classes of Acquiring Fund shares that shareholders will receive in connection with the Reorganization will depend on the class or classes of Target Fund shares that shareholders hold as set forth above under “Comparison of Share Classes and Distribution Arrangements.”

The Target Fund and Acquiring Fund have made representations and warranties in the form of Agreement that are customary in matters such as the Reorganization.

Board Considerations in Approving the Reorganization

resulted in significant product overlap. The Reorganization proposed in this Proxy Statement/Prospectus is part of a larger group of reorganizations across Invesco’s mutual fund platform. The reorganizations are designed to put forth Invesco’s most compelling investment processes and strategies, reduce product overlap and create scale in the resulting funds.

Because of the large number of proposed reorganizations, each Board of Trustees of the Invesco Funds created an ad hoc committee comprised of both Invesco Fund trustees and Van Kampen legacy trustees (the “Ad Hoc Merger Committees”). The Ad Hoc Merger Committee of the Board met separately three times, from September 2, 2010 through October 13, 2010 to discuss the proposed Reorganization. Two separate meetings of the full Board were also held to review and consider the Reorganization, including presentations by the Ad Hoc Merger Committee. The trustees who are not “interested persons,” as that term is defined in the 1940 Act, of the Trust (the “Independent Trustees”) held a separate meeting prior to the meeting of the full Board to consider these matters. The Independent Trustees have been advised on this matter by independent counsel to the Independent Trustees and by the independent Senior Officer, an officer of the Trust who reports directly to the Independent Trustees. The Board requested and received from Invesco Advisers and IDI written materials containing relevant information about the Funds and the proposed Reorganization, including fee and expense information on an actual and pro forma estimated basis, and comparative portfolio composition and performance data.

The Board considered the potential benefits and costs of the Reorganization to the Target Fund, the Acquiring Fund and their respective shareholders. The Board reviewed detailed information comparing the following information for the Target Fund and the Acquiring Fund: (1) investment objectives, policies and restrictions; (2) portfolio management; (3) portfolio composition; (4) the comparative short-term and long-term investment performance; (5) the current expense ratios and expense structures, including contractual investment advisory fees; (6) the expected federal income tax consequences to the Funds, including any impact on capital loss carry forwards; and (7) relative asset size and net purchase (redemption) trends. The Board also considered the benefits to the Target Fund of (i) combining with a similar Fund to create a larger fund with a more diversified shareholder base that may also achieve certain economies of scale as certain fixed expenses are allocated over a larger asset base, and (ii) Invesco Advisers or one of its affiliates’ paying a portion of the expenses related to the reorganizations for those funds that are currently subject to expense caps; (iii) Invesco Advisers’ agreement for certain acquiring funds to cap expenses for one year after the Closing; and (iv) the expected tax-free nature of the reorganizations for each target fund and its shareholders for federal income tax purposes. The Board also considered the overall goal of the reorganizations to rationalize the Invesco Funds to enable IDI to better focus on the combined funds to promote additional asset growth.

With respect to the Reorganization of the Target Fund with the Acquiring Fund, the Board further considered that (i) the advisory fee of the Acquiring Fund is lower than the advisory fee of the Target Fund; (ii) Target Fund shareholders would become shareholders of a Fund with lower overall total expense ratio on a pro forma basis; and (3) Investor Class shares of the Target Fund map to Class A shares of the Acquiring Fund, resulting in an increase in 12b-1 expenses, however Target Fund shareholders will benefit from a reduction in total expense ratio.

Based upon the information and considerations described above, the Board, on behalf of the Target Fund and the Acquiring Fund, approved the Reorganization in order to combine the Target Fund with a similar Fund in terms of investment objectives, strategies and risks, portfolio management and portfolio composition to create a larger fund with a relatively more diversified shareholder base. The Board also determined that shareholders of the Funds could potentially benefit from the growth in assets realized by the Reorganizations, with the potential to achieve certain economies of scale. The Board concluded that the Reorganization is in the best interests of the Target Fund and the Acquiring Fund and that no dilution of value would result to the shareholders of the Target Fund or the Acquiring Fund from the Reorganization. Consequently, the Board approved the Agreement and the Reorganization on October 27, 2010.

Federal Income Tax Considerations

applicable to them and their individual circumstances. These same considerations generally do not apply to shareholders who hold their shares in a tax-deferred account.

	•		no gain or loss will be recognized by the Target Fund or the shareholders of the Target Fund as a result of the Reorganization;

	•		no gain or loss will be recognized by the Acquiring Fund as a result of the Reorganization;

	•		the aggregate tax basis of the shares of the Acquiring Fund to be received by a shareholder of the Target Fund will be the same as the shareholder’s aggregate tax basis of the shares of the Target Fund; and

	•		the holding period of the shares of the Acquiring Fund received by a shareholder of the Target Fund will include the period that a shareholder held the shares of the Target Fund (provided that such shares of the Target Fund are capital assets in the hands of such shareholder as of the Closing).

The tax attributes, including capital loss carryovers, of the Target Fund move to the Acquiring Fund in the Reorganization. The capital loss carryovers of the Target Fund and the Acquiring Fund are available to offset future gains recognized by the combined Fund, subject to limitations under the Code. Where these limitations apply, all or a portion of a Fund’s capital loss carryovers may become unavailable the effect of which may be to accelerate the recognition of taxable gain to the combined Fund and its shareholders post-Closing. First, the capital loss carryovers of the Target Fund, increased by any current year loss or decreased by any current year gain, together with any net unrealized depreciation in the value of its portfolio investments (collectively, its “aggregate capital loss carryovers”), are expected to become subject to an annual limitation. Losses in excess of that limitation may be carried forward to succeeding tax years, subject to an overall eight-year carryover period. The annual limitation will generally equal the net asset value of the Target Fund on the Closing Date multiplied by the “long-term tax-exempt rate” published by the IRS. If the Target Fund has net unrealized built-in gains at the time of Closing the Reorganization (i.e., unrealized appreciation in value of the Fund’s investments), the annual limitation for a taxable year will be increased by the amount of such built-in gains that are recognized in the taxable year. Second, if a Fund has built-in gains at the time of the Reorganization that are realized by the combined Fund in the five-year period following the Reorganization, such built-in gains, when realized, may not be offset by the losses (including any capital loss carryovers and “built in losses”) of the other Fund. Third, the capital losses of the Target Fund that may be used by the Acquiring Fund (including to offset any “built-in gains” of the Target Fund itself) for the first taxable

year ending after the Closing Date will be limited to an amount equal to the capital gain net income of the Acquiring Fund for such taxable year (excluding capital loss carryovers) treated as realized post-Closing based on the number of days remaining in such year. Fourth, the Reorganization may result in an earlier expiration of a Fund’s capital loss carryovers because the Reorganization causes the Target Fund’s tax year to close early in the year of the Reorganization. The aggregate capital loss carryovers of the Funds and the approximate annual limitation on the use by the Acquiring Fund, post-Closing, of the Target Fund’s aggregate capital loss carryovers following the Reorganization are as follows:


	Target Fund			Acquiring Fund
	(000,000s)			(000,000s)
	at 2/28/2010			at 2/28/2010

Aggregate capital loss carryovers on a tax basis (1)		($153.9	)		($69.8	)

Unrealized Net Appreciation (Depreciation) in Investments on a Tax Basis	$	15.1		$	52.7

Aggregate Net Asset Value	$	324.1		$	836.0

Approximate annual limitation (2)	$	12.9			N/A


(1)		Includes realized gain, to the extent not offset by expiring capital loss carryovers, or loss for the current fiscal year determined on the basis of generally accepted accounting principles; excludes any excess capital loss carryovers that are anticipated to expire on or prior to Closing.

(2)		Based on the long-term tax-exempt rate for ownership changes during October 2010 of 3.98%.

The annual limitation on the use of the Target Fund’s aggregate capital loss carryovers will likely limit the use of such losses by the Acquiring Fund, post-Closing, to offset capital gains, if any, it realizes. As of February 28, 2010, the Acquiring Fund has unrealized appreciation in the value of its investments which, if realized prior to Closing, would reduce its available capital loss carryovers. In general, the ability of a fixed income fund to utilize capital loss carryovers is limited because fixed income securities do not generally generate significant capital gains. The ability of the Acquiring Fund to absorb its own capital loss carryovers and those of the Target Fund post-Closing depends upon a variety of factors that can not be known in advance. For more information with respect to each Fund’s capital loss carryovers, please refer to the Fund’s shareholder report.

In addition, if the Acquiring Fund following the Reorganization has proportionately greater unrealized appreciation in its portfolio investments as a percentage of its net asset value than the Target Fund, shareholders of the Target Fund, post-Closing, may receive greater amounts of taxable gain as such portfolio investments are sold than they otherwise might have if the Reorganization had not occurred. The Target Fund’s unrealized appreciation (depreciation) in value of investments on a tax basis as a percentage of its net asset value at February 28, 2010 is 5%, compared to the Acquiring Fund at February 28, 2010 of 6%, and on a combined basis of 6%.

After the Reorganization, shareholders will continue to be responsible for tracking the adjusted tax basis and holding period of their shares for federal income tax purposes.

OTHER MATTERS

Capitalization

The following table sets forth as of September 30, 2010, the total net assets, number of shares outstanding and net asset value per share of each class of each Fund. This information is generally referred to as the “capitalization” of a Fund. The term “pro forma capitalization” means the expected capitalization of the Acquiring Fund after it has combined with the Target Fund. The pro forma capitalization column in the table assumes that the Reorganization has taken place. The capitalizations of the Target Fund, the Acquiring Fund and their classes are likely to be different on the Closing Date as a result of daily share purchase, redemption, and market activity.

1.		The Target Fund and the Acquiring Fund currently have Class A, Class, B, Class C, Class Y and Institutional Class shares outstanding. In addition, the Target Fund has Class R shares outstanding.

2.		Net Assets have been adjusted for the allocated portion of the Target Fund’s expenses to be incurred in connection with the Reorganization. The Reorganization costs have been allocated among all classes based on relative net assets of each class of their respective Fund.

3.		Shares Outstanding have been adjusted for the accumulated change in the number of shares of the Target Fund’s shareholder accounts based on the relative value of the Target Fund’s and the Acquiring Fund’s Net Asset Value Per Share assuming the Reorganization would have taken place on September 30, 2010.

4.		As of September 30, 2010, Class R shares of the Acquiring Fund did not exist. Class R shares were added to the Acquiring Fund in connection with the Reorganization. Class R shares will commence operations at the Net Asset Value Per Share of Acquiring Fund’s Class A shares.

5.		Holders of Invesco Income Fund Investor Class shares will receive Class A shares of the Acquiring Fund upon closing of the Reorganization.

Dissenters’ Rights

Target Fund shareholders will hold shares of the Acquiring Fund, which may also be redeemed at net asset value subject to applicable deferred sales charges and/or redemption fees (if any).

Shareholder Proposals

The Funds do not generally hold annual meetings of shareholders. A shareholder desiring to submit a proposal intended to be presented at any meeting of shareholders of a Target Fund hereafter called should send the proposal to the Target Fund at the Target Fund’s principal offices so that it is received within a reasonable time before the proxy materials are printed and mailed. If the proposed Reorganization is approved and completed for the Target Fund, shareholders of the Target Fund will become shareholders of the Acquiring Fund and, thereafter, will be subject to the notice requirements of the Acquiring Fund. The mere submission of a proposal by a shareholder does not guarantee that such proposal will be included in a proxy statement because compliance with certain rules under the federal securities laws must be complied with before inclusion of the proposal is required. Also, the submission does not mean that the proposal will be presented at a future meeting. For a shareholder proposal to be considered at a future shareholder meeting, it must be a proper matter for consideration under applicable law.

Pro Forma Financial Information

Pro Forma Financial Information
Invesco Van Kampen High Yield Fund into Invesco High Yield Fund

The unaudited pro forma financial information set forth below is for informational purposes only and does not purport to be indicative of the financial condition that actually would have resulted if the Reorganization had been consummated. These pro forma numbers have been estimated in good faith based on information regarding each Target Fund and each Acquiring Fund for the twelve month period ended August 31, 2010. The unaudited pro forma financial information should be read in conjunction with the historical financial statements of the Target Fund and Acquiring Fund, which are available in their respective annual and semi-annual shareholder reports.

Narrative Description of the Pro Forma Effects of the Reorganization

Note 1 — Reorganization

The unaudited pro forma information has been prepared to give effect to the proposed reorganization of the Target Fund into the Acquiring Fund pursuant to an Agreement and Plan of Reorganization (the “Plan”) as of the beginning of the period as indicated below in the table.


		12 Month
Target Fund	Acquiring Fund	Period Ended
Invesco Van Kampen High Yield Fund	Invesco High Yield Fund	08/31/2010

Basis of Pro Forma

The reorganization will be accounted for as a tax-free reorganization of investment companies; therefore, no gain or loss will be recognized by the Acquiring Fund or its shareholders as a result of the reorganization. The Target Fund and the Acquiring Fund are both series of a registered open-end management investment company that issues its shares in separate series. The reorganization would be accomplished by the acquisition of all of the assets and the assumption of all of the liabilities by the Acquiring Fund in exchange for shares of the Acquiring Fund and the distribution of such shares to Target Fund shareholders in complete liquidation of the Target Fund. The table below shows the class and shares that Target Fund shareholders would have received if the reorganization were to have taken place on the period ended date in Note 1.


Target Fund Share Class	Shares Exchanged		Acquiring Fund Share Class
Class A		92,234,693	Class A
Class B		7,524,558	Class B
Class C		11,698,595	Class C
Class Y		3,956,484	Class Y
Institutional Class		5,627,620	Institutional Class

Under accounting principles generally accepted in the United States of America, the historical cost of investment securities will be carried forward to the surviving entity, the Acquiring Fund, and the results of operations of the Acquiring Fund for pre-reorganization periods will not be restated. All securities held by the Target Fund comply with investment objectives, strategies and restrictions of the Acquiring Fund at period ended date in Note 1.

Note 2 — Net Assets

The table below shows the net assets of the Target Fund and the Acquiring Fund and Pro Forma combined net assets as of the dates indicated.


Fund	Net Assets		As-of Date
Invesco Van Kampen High Yield Fund (Target Fund)	$	499,874,783		08/31/2010
Invesco High Yield Fund (Acquiring Fund)	$	876,835,298		08/31/2010
Invesco High Yield Fund (Pro Forma Combined)	$	1,376,710,081		08/31/2010

Note 3 — Pro Forma Adjustments

The table below reflects adjustments to expenses needed to the pro forma combined Fund as if the reorganization had taken place on the first day of the period as disclosed in Note 1. The pro forma information has been derived from the books and records used in calculating daily net asset values of the Target Fund and Acquiring Fund and has been prepared in accordance with accounting principles generally accepted in the United States of America which requires management to make estimates and assumptions that affect this information. Actual results could differ from those estimates.


	Increase (decrease)
Expense Category	in expense
Advisory fees (1)	$	270,778
Administrative services fees (2)		(37,942	)
Professional fees (3)		(52,039	)
Trustees’ and officers fees and benefits (4)		(14,600	)
Fee waiver and/or expense reimbursements (1)		(726,643	)


(1)		Under the terms of the investment advisory contract of the Acquiring Fund, the advisory fees have been adjusted to reflect the advisory fee rates in effect for the Acquiring Fund based on pro forma combined net assets. Correspondingly, advisory fee waivers have been adjusted to reflect the contractual agreement by Invesco Advisers, Inc., the Acquiring Fund’s investment adviser (the “Adviser”), to waive advisory fees and/or reimburse expenses through at least June 30, 2013 as part of the contractual expense limitation agreement of the Acquiring Fund. Upon closing of the Reorganization, the Adviser has contractually agreed through at least June 30, 2013, to waive advisory fees and/or reimburse expenses to the extent necessary to limit total annual fund operating expenses (excluding certain items discussed below) of Class A, Class B, Class C, Class Y, Investor Class and Institutional Class shares to 0.99%, 1.74%, 1.74%, 0.74%, 0.99% and 0.74% of average daily net assets, respectively. In determining the Adviser’s obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the total annual fund operating expenses after fee waiver to exceed the numbers reflected above: (1) interest; (2) taxes; (3) dividend expense on short sales; (4) extraordinary or non-routine items; and (5) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Unless the Board of the Trustees and Invesco mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2013.

(2)		Administrative services fees were adjusted to eliminate the duplicative costs of administering two funds pursuant to the master administrative services agreement for the Target Fund and the Acquiring Fund.

(3)		Professional fees were reduced to eliminate the effects of duplicative fees for audit and legal services.

(4)		Trustees’ and officer’s fees and benefits were reduced to eliminate the effects of duplicative fixed costs of retainer and meeting fees.

No significant accounting policies will change as a result of the reorganization, specifically policies regarding security valuation or compliance with Subchapter M of the Internal Revenue Code.

Note 4 — Reorganization Costs

The Target Fund is expected to incur an estimated $340,000 in reorganization costs. These costs represent the estimated non recurring expense of the Target Fund carrying out its obligations under the Plan and consist of management’s estimate of professional services fees, printing costs and mailing charges related to the proposed reorganizations. Invesco will bear 100% of these costs. The Acquiring Fund is expected to incur approximately $30,000 of expenses in connection with the reorganization and will bear all of these costs and expenses. The pro forma financial information has not been adjusted for any costs related to the reorganization.

Note 5 — Accounting Survivor

The Acquiring Fund will be the accounting survivor. The surviving fund will have the portfolio management team, portfolio composition strategies, investment objective, expense structure, and policies/restrictions of the Acquiring Fund.

(1)		Under the terms of the investment advisory contract of the Acquiring Fund, the advisory fees have been adjusted to reflect the advisory fee rates in effect for the Acquiring Fund based on pro forma combined net assets. Correspondingly, advisory fee waivers and distribution fee waivers have been adjusted to reflect the contractual agreement by Invesco Advisers, Inc., the Acquiring Fund’s investment adviser (the “Adviser”) to waive advisory fees and/or reimburse expenses through at least June 30, 2012 as part of the contractual expense limitation agreement of the Acquiring Fund. Upon closing of the Reorganization, the Adviser for the Acquiring Fund has contractually agreed through at least June 30, 2012, to waive advisory fees and/or reimburse expenses to the extent necessary to limit total annual fund operating expenses (excluding certain items discussed below) of Class A, Class B, Class C, Class R, Class Y and Institutional Class shares to 0.95%, 1.70%, 1.70%, 1.20%, 0.70% and 0.70% of average daily net assets, respectively. In determining the Adviser’s obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the total annual fund operating expenses after fee waiver to exceed the numbers reflected above: (1) interest; (2) taxes; (3) dividend expense on short sales; (4) extraordinary or non-routine items; and (5) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. In addition, the Distributor of the Acquiring Fund agreed through at least June 30, 2012, to waive distribution fees for Class B and Class C shares to the extent necessary to limit 12b-1 fees to 0.59% and 0.95%, respectively of average daily net assets. Unless the Board of the Trustees and Invesco mutually agree to amend or continue the fee waiver agreements, both will terminate on June 30, 2012.

(2)		Administrative services fees were adjusted to eliminate the duplicative costs of administering two funds pursuant to the master administrative services agreement for the Target Fund and the Acquiring Fund.

(3)		Professional fees were reduced to eliminate the effects of duplicative fees for audit and legal services.

No significant accounting policies will change as a result of the reorganization, specifically policies regarding security valuation or compliance with Subchapter M of the Internal Revenue Code.

Note 4 — Reorganization Costs

The Target Fund is expected to incur an estimated $200,000 in reorganization costs and will bear 100% of these costs. These costs represent the estimated non recurring expense of the Target Fund carrying out its obligations under the Plan and consist of management’s estimate of professional services fees, printing costs and mailing charges related to the proposed reorganization.

OTHER INFORMATION


Item 15.		Indemnification

		Indemnification provisions for officers, trustees, and employees of the Registrant are set forth in Article VIII of the Registrant’s Amended and Restated Agreement and Declaration of Trust and Article VIII of its Amended and Restated Bylaws, and are hereby incorporated by reference. See Item 16(1) and (2) below. Under the Amended and Restated Agreement and Declaration of Trust dated September 14, 2005, (i) Trustees or officers, when acting in such capacity, shall not be personally liable for any act, omission or obligation of the Registrant or any Trustee or officer except by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office with the Trust; (ii) every Trustee, officer, employee or agent of the Registrant shall be indemnified to the fullest extent permitted under the Delaware Statutory Trust Act, the Registrant’s Bylaws and other applicable law; (iii) in case any shareholder or former shareholder of the Registrant shall be held to be personally liable solely by reason of his being or having been a shareholder of the Registrant or any portfolio or class and not because of his acts or omissions or for some other reason, the shareholder or former shareholder (or his heirs, executors, administrators or other legal representatives, or, in the case of a corporation or other entity, its corporate or general successor) shall be entitled, out of the assets belonging to the applicable portfolio (or allocable to the applicable class), to be held harmless from and indemnified against all loss and expense arising from such liability in accordance with the Bylaws and applicable law. The Registrant, on behalf of the affected portfolio (or class), shall upon request by the shareholder, assume the defense of any such claim made against the shareholder for any act or obligation of that portfolio (or class).

		The Registrant and other investment companies and their respective officers and trustees are insured under a joint Mutual Fund Directors and Officers Liability Policy, issued by ICI Mutual Insurance Company and certain other domestic insurers, with limits up to $80,000,000 (plus an additional $20,000,000 limit that applies to independent directors/trustees only).

		Section 16 of the Master Investment Advisory Agreement between the Registrant and Invesco Advisers, Inc. (“Invesco”) provides that in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of obligations or duties hereunder on the part of Invesco or any of its officers, directors or employees, that Invesco shall not be subject to liability to the Registrant or to any series of the Registrant, or to any shareholder of any series of the Registrant for any act or omission in the course of, or connected with, rendering services hereunder or for any losses that may be sustained in the purchase, holding or sale of any security. Any liability of Invesco to any series of the Registrant shall not automatically impart liability on the part of Invesco to any other series of the Registrant. No series of the Registrant shall be liable for the obligations of any other series of the Registrant.

C-1


	Section 9 of the Master Intergroup Sub-Advisory Contract for Mutual Funds (the “Sub-Advisory Contract”) between Invesco, on behalf of Registrant, and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Ltd., Invesco Asset Management (Japan) Limited, Invesco Australia Limited, Invesco Hong Kong Limited, Invesco Senior Secured Management, Inc. and Invesco Trimark Ltd. (each a “Sub-Adviser”, collectively the “Sub-Advisers”) provides that the Sub-Adviser shall not be liable for any costs or liabilities arising from any error of judgment or mistake of law or any loss, suffered by any series of the Registrant or the Registrant in connection with the matters to which the Sub-Advisory Contract relates except a loss resulting from willful misfeasance, bad faith or gross negligence on the part of the Sub-Adviser in the performance by the Sub-Adviser of its duties or from reckless disregard by the Sub-Adviser of its obligations and duties under the Sub-Advisory Contract.

	Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the “Act”) may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act will be governed by the final adjudication of such issue.
